HL7 FHIR Security with Basic Auth, OAuth and SSL/TLS 2024-10-21, by Dariusz Suchojad HL7 FHIR Security

Preliminary reading: HL7 FHIR Integrations in Python

FHIR servers offer their APIs using REST, which in turn means that they are HTTP servers under the hood. As a result, a few common security mechanisms can be employed to secure access to the servers when you invoke them.

• Basic Auth
• OAuth
• SSL/TLS encryption

When you integrate with a FHIR server, consult with its maintainers what of these, if any, should be used.

Note that Basic Auth and OAuth, when used over HTTP, are mutually exclusive. The HTTP protocol reserves only one header, called Authorization, for the authorization credentials and there is no standard way in the protocol to use more than one authorization mechanism.

On the other hand, the SSL/TLS encryption is independent of the credentials used and can be employed with Basic Auth, OAuth, or in scenarios when no authorization header is sent at all.

This is why, when you create or update a FHIR connection, you can set Basic Auth or OAuth and SSL/TLS options independently, as in the screenshot below:

Basic Auth

Basic Auth is a combination of username and password credentials. They are allocated in advance by the maintainers of a FHIR server.

To use them in your integrations, create a new Basic Auth definition in the Dashboard, set its password, and assign it to an existing or new outgoing FHIR connection. No restarts nor reloads are required.

OAuth

Authentication with OAuth is built around a notion of short-lived tokens, which are simple strings. Your Zato server has credentials, much like a username and password although they are called a client ID and secret, based on which an authentication server issues tokens that let Zato prove that in fact it does have the correct credentials and that it is allowed to invoke a particular API as it is defined through scopes.

Scopes can be likened to permissions to access a subset of resources from a FHIR server. When Zato receives a token from an authentication server the token is inherently linked to specific scopes within which it can interact with the FHIR server.

That tokens are short-lived means that they need to be refreshed periodically, e.g. at least once per hour Zato needs to ask the authentication server for a new token based on its credentials. This process takes place under the hood and requires no configuration on your part.

To use OAuth in your integrations, create a new OAuth definition in the Dashboard, set its secret, and assign it to an existing or new outgoing FHIR connection. No restarts nor reloads are required.

SSL/TLS encryption

If the FHIR server that a connection points to uses SSL/TLS then a question arises of how to validate the certificate of the Certificate Authority (CA) that signed the certificate that the FHIR server uses. There are several options:

• Skip validation - the certificate will not be validated at all and it will be always accepted.
• Default bundle - the certificate will have to belong to one of the publicly recognized CAs. The bundle contains the same certificates that common web browsers do so this option is good if the FHIR server is available in the public Internet, e.g. https://fhir.example.com
• Custom bundle - if the FHIR server's certificate was signed by an internal, non-public CA then the CA's certificate bundle, in the PEM format, can be uploaded through the Dashboard to make it possible to choose it when the FHIR connection is being created or updated.

Understanding the fundamentals of Single Sign-On systems (SSOs)

Single-Sign On (SSO) is a useful tool for organisations to maintain security, whilst improving the user experience for people who need to log in to multiple tools. In this article, SystemSeed CTO Evgeniy Maslovskiy explains how SSOs work, and how to get the most out of yours.

In part I we explored the pre-requisite in order to code print : having a grasp on the framebuffer.

Here, we are gonna deep inside one of the most overlooked object oriented abastraction : a file and actually print what we can of hello world in 100 lines of code.

The file handler and the file descriptor

These two abstractions are the low level and high level abstractions of the same thing : a view on something more complex which access has been encapsulated in generic methods. Actually when you code a framebuffer driver you provide function pointers that are specialized to your device and you may omit those common to the class. This is done with a double lookup on the major node, minor node number. Of those « generic » methods you have : seek, write, tell, truncate, open, read, close ...
The file handler in python also handles extra bytes (pun) of facilities : like character encoding, stats, and buffering.

Here, we work with the low level abstraction : the file which we access with fileno through its file descriptor. And thanks to this abstraction, you don't care if the underlying implementation fragments the file itself (ex: on a hard drive), you can magically always ask without caring for the gory details to read any arbitrary block or chararacters at any given position.

Two of the most used methods on files here are seek and write.

The file descriptor method write is sensitive to the positionning set by seek. Hence, we can write a line, and position ourselves one line below to write the next line in a character.

matrices as a view of a row based array

When I speak of rows and columns I evocate abstractions that are not related to the framebuffer.

The coordinates are an abstraction we build for convenience to say I want to write from this line at this column.
And since human beings bug after 2 dimensions we split the last dimnension in a vector of dimension 4 called a pixel.
get_at function illustrates our use of this trick to position the (invisible) cursor at any given position on the screen expressed for clarity in size of glyphes.
We could actually code all this exercice through a 3D view of the framebuffer. I just wouldn't be able to pack the code in less than 100 lines of code and would introduce useless abstractions.

But if you have doubt on the numerous seek I do and why I mutiply lines and columns value the way I do check the preceding link for an understanding of raw based array nth matricial dimensionnal views.

fonts, chars glyphs...

Here we are gonna take matrices defining the glyphes (what you actually see on screen) by 8x8 = 64 1D array and map them on the screen with put_char. Put char does a little bit of magic by relying on python to do the chararcter to glyph conversion through the dict lookup that expecting strings does a de factor codepoint to glyph conversion without having to pass the codepoint conversion.

The set of characters to glyphs conversion with their common property is a font.

The hidden console

The console is an abstraction that keeps track of the global states such as : what is the current line we print at. Thus, here, being lazy I use the global variables instead of a singleton named « console » or « term » to keep track of them. But first and foremost, these « abstractions » are just expectations we share in a common mental mode. Like we expect « print » to add a newline at the end of the string and begin the printing at the next line.

The to be finished example

I limited the code to 100 lines so that it's fairly readable. I let as an exercise the following points :

• encoding the missing glyphes in the font to actually be able to write "hello world!",
• handling the edge case of reaching the bottom of the screen,

I want to point out the true python print function is WAY MORE COMPLEX than this terse example and also handle magic conversion from memory objects to their string counterpart (like integers that are converted to their decimal representation), it handles buffering, encoding, and so much more. This is merely a toy to dive into the complexity of the mission at hand.
This example is a part of a project to write « hello world » on the framebuffer in numerous languages, bash included.

Annexe : the code

As usual with these every-two-year posts, probably of direct interest only to California residents. Maybe the more obscure things we're voting on will be a minor curiosity to people elsewhere. I'm a bit late this year, although not as late as last year, so a lot of people may have already voted, but I've been doing this for a while and wanted to keep it up.

This post will only be about the ballot propositions. I don't have anything useful to say about the candidates that isn't hyper-local. I doubt anyone who has read my posts will be surprised by which candidates I'm voting for.

As always with Calfornia ballot propositions, it's worth paying close attention to which propositions were put on the ballot by the legislature, usually because there's some state law requirement (often that I disagree with) that they be voted on by the public, and propositions that were put on the ballot by voter petition. The latter are often poorly written and have hidden problems. As a general rule of thumb, I tend to default to voting against propositions added by petition. This year, one can conveniently distinguish by number: the single-digit propositions were added by the legislature, and the two-digit ones were added by petition.

Proposition 2: YES. Issue $10 billion in bonds for public school infrastructure improvements. I generally vote in favor of spending measures like this unless they have some obvious problem. The opposition argument is a deranged rant against immigrants and government debt and fails to point out actual problems. The opposition argument also claims this will result in higher property taxes and, seriously, if only that were true. That would make me even more strongly in favor of it.

Proposition 3: YES. Enshrines the right to marriage without regard to sex or race into the California state constitution. This is already the law given US Supreme Court decisions, but fixing California state law is a long-overdue and obvious cleanup step. One of the quixotic things I would do if I were ever in government, which I will never be, would be to try to clean up the laws to make them match reality, repealing all of the dead clauses that were overturned by court decisions or are never enforced. I am in favor of all measures in this direction even when I don't agree with the direction of the change; here, as a bonus, I also strongly agree with the change.

Proposition 4: YES. Issue $10 billion in bonds for infrastructure improvements to mitigate climate risk. This is basically the same argument as Proposition 2. The one drawback of this measure is that it's kind of a mixed grab bag of stuff and probably some of it should be supported out of the general budget rather than bonds, but I consider this a minor problem. We definitely need to ramp up climate risk mitigation efforts.

Proposition 5: YES. Reduces the required super-majority to pass local bond measures for affordable housing from 67% to 55%. The fact that this requires a supermajority at all is absurd, California desperately needs to build more housing of any kind however we can, and publicly funded housing is an excellent idea.

Proposition 6: YES. Eliminates "involuntary servitude" (in other words, "temporary" slavery) as a legally permissible punishment for crimes in the state of California. I'm one of the people who think the 13th Amendment to the US Constitution shouldn't have an exception for punishment for crimes, so obviously I'm in favor of this. This is one very, very tiny step towards improving the absolutely atrocious prison conditions in the state.

Proposition 32: YES. Raises the minimum wage to $18 per hour from the current $16 per hour, over two years, and ties it to inflation. This is one of the rare petition-based propositions that I will vote in favor of because it's very straightforward, we clearly should be raising the minimum wage, and living in California is absurdly expensive because we refuse to build more housing (see Propositions 5 and 33). The opposition argument is the standard lie that a higher minimum wage will increase unemployment, which we know from numerous other natural experiments is simply not true.

Proposition 33: NO. Repeals Costa-Hawkins, which prohibits local municipalities from enacting rent control on properties built after 1995. This one is going to split the progressive vote rather badly, I suspect.

California has a housing crisis caused by not enough housing supply. It is not due to vacant housing, as much as some people would like you to believe that; the numbers just don't add up. There are way more people living here and wanting to live here than there is housing, so we need to build more housing.

Rent control serves a valuable social function of providing stability to people who already have housing, but it doesn't help, and can hurt, the project of meeting actual housing demand. Rent control alone creates a two-tier system where people who have housing are protected but people who don't have housing have an even harder time getting housing than they do today. It's therefore quite consistent with the general NIMBY playbook of trying to protect the people who already have housing by making life harder for the people who do not, while keeping the housing supply essentially static.

I am in favor of rent control in conjunction with real measures to increase the housing supply. I am therefore opposed to this proposition, which allows rent control without any effort to increase housing supply. I am quite certain that, if this passes, some municipalities will use it to make constructing new high-density housing incredibly difficult by requiring it all be rent-controlled low-income housing, thus cutting off the supply of multi-tenant market-rate housing entirely. This is already a common political goal in the part of California where I live. Local neighborhood groups advocate for exactly this routinely in local political fights.

Give me a mandate for new construction that breaks local zoning obstructionism, including new market-rate housing to maintain a healthy lifecycle of housing aging into affordable housing as wealthy people move into new market-rate housing, and I will gladly support rent control measures as part of that package. But rent control on its own just allocates winners and losers without addressing the underlying problem.

Proposition 34: NO. This is an excellent example of why I vote against petition propositions by default. This is a law designed to affect exactly one organization in the state of California: the AIDS Healthcare Foundation. The reason for this targeting is disputed; one side claims it's because of the AHF support for Proposition 33, and another side claims it's because AHF is a slumlord abusing California state funding. I have no idea which side of this is true. I also don't care, because I am fundamentally opposed to writing laws this way. Laws should establish general, fair principles that are broadly applicable, not be written with bizarrely specific conditions (health care providers that operate multifamily housing) that will only be met by a single organization. This kind of nonsense creates bad legal codes and the legal equivalent of technical debt. Just don't do this.

Proposition 35: YES. I am, reluctantly, voting in favor of this even though it is a petition proposition because it looks like a useful simplification and cleanup of state health care funding, makes an expiring tax permanent, and is supported by a very wide range of organizations that I generally trust to know what they're talking about. No opposition argument was filed, which I think is telling.

Proposition 36: NO. I am resigned to voting down attempts to start new "war on drugs" nonsense for the rest of my life because the people who believe in this crap will never, ever, ever stop. This one has bonus shoplifting fear-mongering attached, something that touches on nasty local politics that have included large retail chains manipulating crime report statistics to give the impression that shoplifting is up dramatically. It's yet another round of the truly horrific California "three strikes" criminal penalty obsession, which completely misunderstands both the causes of crime and the (almost nonexistent) effectiveness of harsh punishment as deterrence.

Python and Sigstore About • Blog • Cool URLs Python and Sigstore

Published 2024-10-21 by Seth Larson
Reading time: minutes

This critical role would not be possible without funding from the Alpha-Omega project. Massive thank-you to Alpha-Omega for investing in the security of the Python ecosystem!

I was a guest on the Open Source Security podcast this week talking about Sigstore and Python among other things I'm working on at the Python Software Foundation.

Sigstore is a digital signing method that has been used by CPython since 3.11.0 which focuses on ergonomics and uses short-lived keys with strongly-bound human-readable identities via OpenID Connect.

CPython also provides digital signatures using PGP and has been doing so for much longer. Below is a diagram showing the current state of affairs:

Distro (Offline?)    Distro (Offline?)    python.orgpython.orgGitHubGitHubSource Code (tar.gz)Source Code (tar.gz)PGP SignaturePGP SignatureSigstore Bundle

ReleaseManagerReleaseMan...Rebuild from sourceRebuild from...Not used for verification
Not used for...Text is not SVG - cannot display
CPython offers two verification methods: PGP and Sigstore. Verifiers choose which method to use.

From this diagram you can see the two "sources" of identity provided by PGP and Sigstore both link back to release managers. PGP relies on private keys which are maintained and protected by individual release managers to create signatures of artifacts. Sigstore uses third-parties which support OpenID Connect such as GitHub and Google to bind a human-readable identity like "thomas@python.org" to a signing certificate and signature that can be later verified.

Why Sigstore?

The problem is that securely maintaining PGP private keys is not an easy task and the burden rests on volunteers for a minimum of 7 years (1 year of pre-releases then 5 years of bug and security fixes across at least two consecutive releases). Contrast that experience to Sigstore where release managers only need to click a button to OAuth sign-in during the release process.

Sigstore externalizes the operational burden of maintaining long-lived signing keys from individual volunteers to teams of people who run an identity platform professionally and the public-good code-signing certificate authority Fulcio. This seems like a pretty good trade-off, considering we already trust these platforms' identity management teams for things like GitHub accounts.

For this reason, I've authored PEP 761 providing a deprecation and discontinuance plan of PGP signatures for CPython artifacts. You can join the discussion of this PEP on discuss.python.org. Big thank-you to Hugo van Kemenade, the release manager for Python 3.14 for sponsoring my first PEP and helping me with the process and thanks to William Woodruff for reviewing the PEP draft and explaining the nitty-gritty details of Sigstore.

This PEP deprecates the expectation that future CPython releases will provide PGP signatures and sets a timeline for discontinuance (Python 3.14) and a mechanism for that timeline to be extended by a vote of the Steering Council, if necessary.

What do verifiers need?

Signatures are only useful if they are verified, so we must weigh the needs of verifiers!

CPython's expected downstream verifiers are primarily "distributions" of CPython, such as through a Linux distro (Debian, Fedora, Gentoo, etc) or in a container image. There are other distributions of Python such as pyenv and python-build-standalone.

These users of CPython's source code are great places to verify signatures, as they're likely to be high value targets themselves and can provide a consistent stream of verifications. If any one signature verification were to fail, it would signal that something is wrong with upstream CPython artifacts or python.org and would likely be investigated and remediated quickly.

This further constrains attackers looking to affect CPython downstream users, as compromising python.org would no longer be enough. Instead, attackers would need to compromise the build infrastructure or CPython source code.

From discussions, the requirements that I've gathered from verifiers are:

• Need a tool for verification that can be packaged by distros. The recommended tool for verifying with a CLI is either Cosign or sigstore-python, both of which have challenges for Linux distro packagers.
• OS packages would require Cosign to be packaged in those OS package managers. This isn't trivial as it requires the Go toolchain to build.
• Docker and other container images want verification tools to be available at the OS level. Needing to pull these externally (from Cosign's GitHub releases) would require multi-stage builds which they want to avoid if possible. Today Cosign is available in Alpine, but not yet in Debian (but there is the beginnings of support), Gentoo, or Fedora.
• Offline verification is important. Many package ecosystems ship the signatures inside the packages to enable "build from source" (such as Gentoo), and there's no guarantee that the package is being built online. It's okay that revocation or root of trust updates can't happen when offline. Cosign and other Sigstore verification tools support offline verification if the root of trust is "bundled" as a file locally.
• Online periodic updates to revocations and root of trust. Cosign and other Sigstore verifiers supports this use-case as the default behavior.

Overall, the availability of Cosign in OS package managers appears to be the biggest blocker to see adoption for verifying CPython's Sigstore signatures.

Why adopt a new signature method?

So why have CPython's Sigstore signatures not seen adoption despite being available for multiple years? Here's a short list of self-reinforcing reasons:

• Verifiers don't need to adopt the new signature method (Sigstore), because the existing one (PGP) works and there's no expectation for discontinuance.
• Signers can't migrate away from the old signature method because there's apparent demand from verifiers for the old signature method.
• Verifiers don't try or test the new signature method, so the maintainers of signature tooling can't learn about or improve verifier use-cases.
• Concurrently supporting multiple signature methods is more work for both signers and verifiers.
• There are fewer available signatures using the new signing method, so the value of adopting the method as a verifier is less (but maybe this will change soon?).

Keep in mind that almost everyone involved in the above scenarios are volunteers. Doing work to adopt a new process when existing processes are working can feel like "busy-work", but I don't think that's the case for Sigstore.

Sigstore's benefits for ergonomics paired with its ability to use workload identity are two stand-out features compared to PGP. Workload identity being extra important now that many projects are moving to hosted build infrastructure for releases.

Workload Identity

Sigstore supporting workload identity means that release manager accounts can no longer be hijacked to produce bad signatures. Artifacts get signed by the build infrastructure provider directly:

Distro (Offline?)Distro (Offline?)python.orgpython.orgGitHubGitHubSource Code (tar.gz)Source Code (tar.gz)Sigstore Bundle

ReleaseInfraCPython...Distro
Package
(deb, rpm)Distro...Distro
Build
InfraDistro...Accounts (GitHub, Gmail)Accounts (Git...


ReleaseManagerReleaseMan...Rebuild from sourceRebuild from...
Workload identity: verify artifacts came from CPython release infra

Switching to workload identity also means downstream verifiers no longer need to make changes when new release managers join the project, the expected identity would always be gh/python/release-tools/....

We still have a ways to go to adopt workload identity for CPython because our macOS and Windows release processes don't use hosted build platforms that support OpenID Connect and Sigstore. That means that for now we'll keep using release manager identities.

But this future may not be far off for Python packages hosted on PyPI...

Many more signatures are coming!

William Woodruff and the team at Trail of Bits have authored PEP 740 which is provisionally accepted. The PEP specifies how attestations that can be verified by PyPI (like Sigstore) using workload identities specified with the secure publishing feature "Trusted Publishers" and then served alongside artifacts on PyPI.

There's a lot more to this story (but it's not for me to tell). Given Trusted Publishers' success, there clearly are exciting times are ahead. Subscribe to the PyPI blog to learn more once the project is complete.

Ada Lovelace Day was celebrated on October 8 in 2024, and on this occasion, to celebrate and raise awareness of the contributions of women to the STEM fields we interviewed some of the women in Debian.

Here we share their thoughts, comments, and concerns with the hope of inspiring more women to become part of the Sciences, and of course, to work inside of Debian.

This article was simulcasted to the debian-women mail list.

Beatrice Torracca

1. Who are you?

I am Beatrice, I am Italian. Internet technology and everything computer-related is just a hobby for me, not my line of work or the subject of my academic studies. I have too many interests and too little time. I would like to do lots of things and at the same time I am too Oblomovian to do any.

2. How did you get introduced to Debian?

As a user I started using newsgroups when I had my first dialup connection and there was always talk about this strange thing called Linux. Since moving from DR DOS to Windows was a shock for me, feeling like I lost the control of my machine, I tried Linux with Debian Potato and I never strayed away from Debian since then for my personal equipment.

3. How long have you been into Debian?

Define "into". As a user... since Potato, too many years to count. As a contributor, a similar amount of time, since early 2000 I think. My first archived email about contributing to the translation of the description of Debian packages dates 2001.

4. Are you using Debian in your daily life? If yes, how?

Yes!! I use testing. I have it on my desktop PC at home and I have it on my laptop. The desktop is where I have a local IMAP server that fetches all the mails of my email accounts, and where I sync and back up all my data. On both I do day-to-day stuff (from email to online banking, from shopping to taxes), all forms of entertainment, a bit of work if I have to work from home (GNU R for statistics, LibreOffice... the usual suspects). At work I am required to have another OS, sadly, but I am working on setting up a Debian Live system to use there too. Plus if at work we start doing bioinformatics there might be a Linux machine in our future... I will of course suggest and hope for a Debian system.

5. Do you have any suggestions to improve women's participation in Debian?

This is a tough one. I am not sure. Maybe, more visibility for the women already in the Debian Project, and make the newcomers feel seen, valued and welcomed. A respectful and safe environment is key too, of course, but I think Debian made huge progress in that aspect with the Code of Conduct. I am a big fan of promoting diversity and inclusion; there is always room for improvement.

Ileana Dumitrescu (ildumi)

1. Who are you?

I am just a girl in the world who likes cats and packaging Free Software.

2. How did you get introduced to Debian?

I was tinkering with a computer running Debian a few years ago, and I decided to learn more about Free Software. After a search or two, I found Debian Women.

3. How long have you been into Debian?

I started looking into contributing to Debian in 2021. After contacting Debian Women, I received a lot of information and helpful advice on different ways I could contribute, and I decided package maintenance was the best fit for me. I eventually became a Debian Maintainer in 2023, and I continue to maintain a few packages in my spare time.

4. Are you using Debian in your daily life? If yes, how?

Yes, it is my favourite GNU/Linux operating system! I use it for email, chatting, browsing, packaging, etc.

5. Do you have any suggestions to improve women's participation in Debian?

The mailing list for Debian Women may attract more participation if it is utilized more. It is where I started, and I imagine participation would increase if it is more engaging.

Kathara Sasikumar (kathara)

1. Who are you?

I'm Kathara Sasikumar, 22 years old and a recent Debian user turned Maintainer from India. I try to become a creative person through sketching or playing guitar chords, but it doesn't work! xD

2. How did you get introduced to Debian?

When I first started college, I was that overly enthusiastic student who signed up for every club and volunteered for anything that crossed my path just like every other fresher.

But then, the pandemic hit, and like many, I hit a low point. COVID depression was real, and I was feeling pretty down. Around this time, the FOSS Club at my college suddenly became more active. My friends, knowing I had a love for free software, pushed me to join the club. They thought it might help me lift my spirits and get out of the slump I was in.

At first, I joined only out of peer pressure, but once I got involved, the club really took off. FOSS Club became more and more active during the pandemic, and I found myself spending more and more time with it.

A year later, we had the opportunity to host a MiniDebConf at our college. Where I got to meet a lot of Debian developers and maintainers, attending their talks and talking with them gave me a wider perspective on Debian, and I loved the Debian philosophy.

At that time, I had been distro hopping but never quite settled down. I occasionally used Debian but never stuck around. However, after the MiniDebConf, I found myself using Debian more consistently, and it truly connected with me. The community was incredibly warm and welcoming, which made all the difference.

3. How long have you been into Debian?

Now, I've been using Debian as my daily driver for about a year.

4. Are you using Debian in your daily life? If yes, how?

It has become my primary distro, and I use it every day for continuous learning and working on various software projects with free and open-source tools. Plus, I've recently become a Debian Maintainer (DM) and have taken on the responsibility of maintaining a few packages. I'm looking forward to contributing more to the Debian community 🙂

Rhonda D'Vine (rhonda)

1. Who are you?

My name is Rhonda, my pronouns are she/her, or per/pers. I'm 51 years old, working in IT.

2. How did you get introduced to Debian?

I was already looking into Linux because of university, first it was SuSE. And people played around with gtk. But when they packaged GNOME and it just didn't even install I looked for alternatives. A working colleague from back then gave me a CD of Debian. Though I couldn't install from it because Slink didn't recognize the pcmcia drive. I had to install it via floppy disks, but apart from that it was quite well done. And the early GNOME was working, so I never looked back. 🙂

3. How long have you been into Debian?

Even before I was more involved, a colleague asked me whether I could help with translating the release documentation. That was my first contribution to Debian, for the slink release in early 1999. And I was using some other software before on my SuSE systems, and I wanted to continue to use them on Debian obviously. So that's how I got involved with packaging in Debian. But I continued to help with translation work, for a long period of time I was almost the only person active for the German part of the website.

4. Are you using Debian in your daily life? If yes, how?

Being involved with Debian was a big part of the reason I got into my jobs since a long time now. I always worked with maintaining Debian (or Ubuntu) systems. Privately I run Debian on my laptop, with occasionally switching to Windows in dual boot when (rarely) needed.

5. Do you have any suggestions to improve women's participation in Debian?

There are factors that we can't influence, like that a lot of women are pushed into care work because patriarchal structures work that way, and don't have the time nor energy to invest a lot into other things. But we could learn to appreciate smaller contributions better, and not focus so much on the quantity of contributions. When we look at longer discussions on mailing lists, those that write more mails actually don't contribute more to the discussion, they often repeat themselves without adding more substance. Through working on our own discussion patterns this could create a more welcoming environment for a lot of people.

Sophie Brun (sophieb)

1. Who are you?

I'm a 44 years old French woman. I'm married and I have 2 sons.

2. How did you get introduced to Debian?

In 2004 my boyfriend (now my husband) installed Debian on my personal computer to introduce me to Debian. I knew almost nothing about Open Source. During my engineering studies, a professor mentioned the existence of Linux, Red Hat in particular, but without giving any details.

I learnt Debian by using and reading (in advance) The Debian Administrator's Handbook.

3. How long have you been into Debian?

I've been a user since 2004. But I only started contributing to Debian in 2015: I had quit my job and I wanted to work on something more meaningful. That's why I joined my husband in Freexian, his company. Unlike most people I think, I started contributing to Debian for my work. I only became a DD in 2021 under gentle social pressure and when I felt confident enough.

4. Are you using Debian in your daily life? If yes, how?

Of course I use Debian in my professional life for almost all the tasks: from administrative tasks to Debian packaging.

I also use Debian in my personal life. I have very basic needs: Firefox, LibreOffice, GnuCash and Rhythmbox are the main applications I need.

Sruthi Chandran (srud)

1. Who are you?

A feminist, a librarian turned Free Software advocate and a Debian Developer. Part of Debian Outreach team and DebConf Committee.

2. How did you get introduced to Debian?

I got introduced to the free software world and Debian through my husband. I attended many Debian events with him. During one such event, out of curiosity, I participated in a Debian packaging workshop. Just after that I visited a Tibetan community in India and they mentioned that there was no proper Tibetan font in GNU/Linux. Tibetan font was my first package in Debian.

3. How long have you been into Debian?

I have been contributing to Debian since 2016 and Debian Developer since 2019.

4. Are you using Debian in your daily life? If yes, how?

I haven't used any other distro on my laptop since I got introduced to Debian.

5. Do you have any suggestions to improve women's participation in Debian?

I was involved with actively mentoring newcomers to Debian since I started contributing myself. I specially work towards reducing the gender gap inside the Debian and Free Software community in general. In my experience, I believe that visibility of already existing women in the community will encourage more women to participate. Also I think we should reintroduce mentoring through debian-women.

Tássia Camões Araújo (tassia)

1. Who are you?

Tássia Camões Araújo, a Brazilian living in Canada. I'm a passionate learner who tries to push myself out of my comfort zone and always find something new to learn. I also love to mentor people on their learning journey. But I don't consider myself a typical geek. My challenge has always been to not get distracted by the next project before I finish the one I have in my hands. That said, I love being part of a community of geeks and feel empowered by it. I love Debian for its technical excellence, and it's always reassuring to know that someone is taking care of the things I don't like or can't do. When I'm not around computers, one of my favorite things is to feel the wind on my cheeks, usually while skating or riding a bike; I also love music, and I'm always singing a melody in my head.

2. How did you get introduced to Debian?

As a student, I was privileged to be introduced to FLOSS at the same time I was introduced to computer programming. My university could not afford to have labs in the usual proprietary software model, and what seemed like a limitation at the time turned out to be a great learning opportunity for me and my colleagues. I joined this student-led initiative to "liberate" our servers and build LTSP-based labs - where a single powerful computer could power a few dozen diskless thin clients. How revolutionary it was at the time! And what an achievement! From students to students, all using Debian. Most of that group became close friends; I've married one of them, and a few of them also found their way to Debian.

3. How long have you been into Debian?

I first used Debian in 2001, but my first real connection with the community was attending DebConf 2004. Since then, going to DebConfs has become a habit. It is that moment in the year when I reconnect with the global community and my motivation to contribute is boosted. And you know, in 20 years I've seen people become parents, grandparents, children grow up; we've had our own child and had the pleasure of introducing him to the community; we've mourned the loss of friends and healed together. I'd say Debian is like family, but not the kind you get at random once you're born, Debian is my family by choice.

4. Are you using Debian in your daily life? If yes, how?

These days I teach at Vanier College in Montréal. My favorite course to teach is UNIX, which I have the pleasure of teaching mostly using Debian. I try to inspire my students to discover Debian and other FLOSS projects, and we are happy to run a FLOSS club with participation from students, staff and alumni. I love to see these curious young minds put to the service of FLOSS. It is like recruiting soldiers for a good battle, and one that can change their lives, as it certainly did mine.

5. Do you have any suggestions to improve women's participation in Debian?

I think the most effective way to inspire other women is to give visibility to active women in our community. Speaking at conferences, publishing content, being vocal about what we do so that other women can see us and see themselves in those positions in the future. It's not easy, and I don't like being in the spotlight. It took me a long time to get comfortable with public speaking, so I can understand the struggle of those who don't want to expose themselves. But I believe that this space of vulnerability can open the way to new connections. It can inspire trust and ultimately motivate our next generation. It's with this in mind that I publish these lines.

Another point we can't neglect is that in Debian we work on a volunteer basis, and this in itself puts us at a great disadvantage. In our societies, women usually take a heavier load than their partners in terms of caretaking and other invisible tasks, so it is hard to afford the free time needed to volunteer. This is one of the reasons why I bring my son to the conferences I attend, and so far I have received all the support I need to attend DebConfs with him. It is a way to share the caregiving burden with our community - it takes a village to raise a child. Besides allowing us to participate, it also serves to show other women (and men) that you can have a family life and still contribute to Debian.

My feeling is that we are not doing super well in terms of diversity in Debian at the moment, but that should not discourage us at all. That's the way it is now, but that doesn't mean it will always be that way. I feel like we go through cycles. I remember times when we had many more active female contributors, and I'm confident that we can improve our ratio again in the future. In the meantime, I just try to keep going, do my part, attract those I can, reassure those who are too scared to come closer. Debian is a wonderful community, it is a family, and of course a family cannot do without us, the women.

These interviews were conducted via email exchanges in October, 2024. Thanks to all the wonderful women who participated in this interview. We really appreciate your contributions in Debian and to Free/Libre software.

In the past I haven’t had a high opinion of MG cars, decades ago they were small and expensive and didn’t seem to offer anything I wanted. As there’s a conveniently located MG dealer I decided to try out an MG electric car and see if they are any good. I brought two friends along who are also interested in new technology.

I went to the MG dealer without any preconceptions or much prior knowledge of the MG electric cars apart from having vaguely noticed that they were significantly cheaper than Teslas. I told the salesperson that I didn’t have a model in mind and I just wanted to see what MG offers, so they offered me a test driver of a “MG4 64 EXCITE”. The MG web site isn’t very good and doesn’t give an indication of what this model costs, my recollection is that it’s something like $40,000, the base model is advertised at $30,990. I’m not particularly interested in paying for extras above the base model and the only really desirable feature that the “Excite 64” offers over the “Excite 51” is the extra range (the numbers 51 and 64 represent the battery capacity in KWh). The base model has a claimed range of 350KM which is more than I drive in a typical week, generally there are only about 4 days a year when I need to drive more than 300KM in a day and on those rare days I can spend a bit of time at a charging station without much inconvenience.

The experience of driving an MG4 is not much different from other EVs I’ve driven, the difference between that and the Genesis GV60 (which was advertised at $117,000) [1] isn’t significant. The Genesis has some nice camera features giving views from all directions and showing a view of the side on the dash when you put your turn indicator on. Also some models of Genesis (not the one I test drove) have cameras instead of side mirrors. The MG4 lacks most of those cameras but has a very effective reversing camera which estimates the distance to an “obstacle” behind you in cm. Some of the MG electric cars have a sunroof or moonroof (sunroof that just opens to transparent glass not open to the air), the one I tested didn’t have them and I didn’t feel I was missing much. While a moonroof is a nice feature I probably won’t want to pay as much extra as they will demand for it.

The dash of the MG4 doesn’t have any simulation of the old fashioned dash unlike the Genesis GV60 which had a display in the same location as is traditionally used which displays analogue instruments (except when the turn indicators are on). The MG4 has two tablets, a big one in the middle of the front for controlling heating/cooling and probably other things like the radio and a small one visible through the steering wheel which has the instruments. I didn’t have to think about the instruments, they just did the job which is great.

For second hand cars I looked at AutoTrader which seems to be the only Australian site for second hand cars that allows specifying electric as a search criteria [2]. For the EVs advertised on that site the cheapest are around $13,000 for cars about 10 years old and $21,000 for a 5yo LEAF. If you could only afford to spend $21,000 on a car then a 5yo LEAF would definitely be better than nothing, but when comparing a 5yo car for $21,000 and a new car for $31,000 the new car is the obvious choice if you can afford it. There was an Australian company importing used LEAFs and other EVs and selling them over the web for low prices, if they were still around and still selling LEAFs for $15,000 then that would make LEAF vs MG3 a difficult decision for me. But with the current prices for second hand LEAFs the decision is easy.

When I enrolled for the test drive the dealer took my email address and sent me an automated message with details about the test drive and an email address to ask for more information. The email address they used bounced all mail, even from my gmail account. They had a contact form on their web site but that also doesn’t get a response. MG really should periodically test their dealer’s email addresses, they are probably losing sales because of this.

On the same day I visited a Hyundai dealer to see what they had to offer. A salesman there said that the cheapest Hyundai was $60,000 and suggested that I go elsewhere if I am prepared to buy a lesser car to save money. I don’t need to get negged by a car dealer and I really don’t think there’s much scope for a car to be significantly better than the MG3 while also not competing with the Genesis cars. Genesis is a Hyundai brand and their cars are very nice, but the prices are well outside the range I’m prepared to pay.

Next I have to try the BYD. From what I’ve heard they are mostly selling somewhat expensive cars in Australia (a colleague recently got one which was about $60,000 which he is extremely happy with) but hopefully they have some of the cheaper ones available too. I don’t want to flex on my neighbors, I just want a reliable and moderately comfortable car that doesn’t cost too much.

Hey folks! Apologies for the long gap since my last post. A lot has happened both personally and professionally—I got a new job and relocated, which led to me extending my GSoC deadline to wrap up the remaining tasks. I’m happy to share that I’ve now completed everything, and all the pending MRs related to my GSoC work have been merged. Here’s a quick overview:

MRs merged:

• Reset form implementation in Okular : Okular now has form reset functionality, allowing you to clear fields or return them to their default values. !MR1007
• Support for MouseDown, MouseEnter and MouseExit events : The corresponding event object is now generated when these mouse events are triggered. !MR994
• Keystroke, Validate, Calculate and Format event support for Comboboxes : These essential events were previously not triggered for comboboxes. This MR adds support for them. !MR1027
• Fix order of execution of events for text form fields : Keystroke, Validate, Calculate, and Format actions weren’t always executed in the correct order, especially during undo/redo or when modified via JavaScript. This MR fixes that and ensures KVCF actions are only triggered when a field value is committed, improving keyboard usability. !MR1002
• Support for modifying the appearance stream text in form field choice (Poppler) : Added functionality to modify appearance stream text in form fields without altering their actual values. !MR1590
• SubmitForm functionality (Poppler) : Support for reading the SubmitForm action was added to Poppler. While Okular doesn’t yet implement the actual submission process, this lays the groundwork for future integration. !MR1579

Future Scope:

Although much progress has been made during GSoC’24, there are still many areas where Okular’s PDF form functionality could be expanded:

• The actual submission of forms in Okular can be built on top of the SubmitForm action now supported by Poppler.
• Adding support for the SelectionChange event in ListBoxes would enhance their interactivity.
• Additional functions could be implemented for CheckBoxes, ComboBoxes, and ListBoxes, such as programmatically checking items, clearing, deleting, inserting, and setting items. Some of these changes would also require updates to Poppler.
• Improving keyboard navigation for form fields could further boost accessibility and ease of use.

Conclusion:

Participating in GSoC with KDE and contributing to Okular has been an incredible learning experience, and I’m proud of the contributions made. Huge thanks to my mentor, Albert Astals Cid, for his constant support, guidance, and patience through all my mistakes. Special thanks to Sune Vuorela for his reviews and insights which helped me learn a lot, and to the KDE Mentorship and GSoC teams for their indirect but invaluable help. I’m looking forward to continuing my journey with KDE.

See you next time. Cheers!

The « hello world » example is about standing on the shoulders of the giant and learn how to use function as tools.

Most coders will use print during their whole life without actually coding it. However, it is a fun exercise.

The framebuffer

Given you are on linux you probably have a device named /dev/fb0 if you don't, you can't do this. The framebuffer is a view of the linear graphical memory used by your video card where what you see on the screen is stored ... at the condition you are in console mode and you have the rights.

On my debian centric distribution, to give the_user permissions to write in the framebuffer I must add the_user to group_video. This can be done with sudo adduser the_user video or sudo vigr.

Then, you have to be in console mode. To switch from xorg/wayland to the console back and forth I use the Ctrl + Alt + Fn combination to switch off from X and Alt + Fn to switch back to X (it's called switching the virtual console).

Once this is done you check you have rights by doing cat /dev/urandom > /dev/fb0 which should fill your screen with random colors and insult you stating there is no more room left on the device. SNAFU : everyhting works as intended.


The pixel

Framebuffer don't know about pixels made of Red, Green, Blue and alpha (given you have a video card that is less than 20 years old), they are just made of memory. We will have to slowly build up our understanding of what this is all about.

The in memory layout may differ according to the hardware, some are having a RGBA layout, mine, the i915 is having a BGRA layout. The following example may need to be rewritten with different hardware if the output is not consistent with your assumption.

Determining the memory layout and coordinates

We will do a test and validate code session : first we make assumption on where the colours are by writting 3 squares of Red, Blue and Green on the screen, then, we will snapshot the screen.

$ cat fb.py #!/usr/bin/env python3 from struct import pack w,h =map(int, open("/sys/class/graphics/fb0/virtual_size").read().split(",")) midx = w//2 midy = h//2 encode = lambda b,g,r,a : pack("4B",b,g,r,a) with open("/dev/fb0", "wb") as f: for y in range(0,h): for x in range(0,w): f.write(encode( not x%100 and 0xA0 or x<midx and 0xFF or 0, #blue y<midy and 0xFF or 0, #green x>midx and y>midy and 0xFF or 0, #red 0, )) The only « trick » is the use of pack to encode the four colour bytes in a byte array that is written to the framebuffer filehandler. If the code works correctly we should validate the following assumptions:

• coordinates are such as 0 is top left of the screen where green and blue should superpose
• my 1920x1080 screen should have 19 weired stripes (hence validating the geometry)
• each colours should be in its square, red bottom right, green top right, blue bottom left.
• RAM as a char device is accessing a low level file

And if the world is consistent we can read from the framebuffer and snapshot it in the most trivial picture encoding witch is Portable PixMap format. A portable Pixmap is made of

• a magic number P3 followed by
• width
• height
• the maximum colour value (here 255)
• the 3 colour bytes Red, Blue, Green without Alpha value per pixel

The code for this is straigh forward : $ cat snap.py #!/usr/bin/env python from struct import unpack w,h = map( int,open("/sys/class/graphics/fb0/virtual_size").read().split(",")) # returns b g r a decode = lambda pixel : unpack("4B", pixel) def pr(b,g,r,a): print("%d %d %d" % (r,g,b)) print(f"""P3 {w} {h} 255 """) with open("/dev/fb0", "rb") as fin: while pixel := fin.read(4): pr(*decode(pixel)) Here the only trick is we use the symetrical function of pack, unpack to decode the pixel in the four colour bytes.

wrapping up part one

Asumming you can install fim the framebuffer image wiewer and you installed imagemagick : you can now do ./fb.py && snap.py > this.ppm && convert this.ppm this.jpg && fim this.jpg Doing so, you should have the same picture showing twice without an error like this : As an exercise, you can vary the fb.py to make funny output, or code a PPM viewer that print back your ppm to the screen.

Hello again, sorry it’s been a while since the last post. In this case, I’m doing a never-before-seen multi-month post!

This may be the last post in this series, as the KDE Promo team has launched “This Week in KDE Apps” which covers my work here (and I also have plans to contribute to… 😅) Nate Graham typically reports on my Plasma changes in his “This Week in Plasma” series. All that would be left is the uninteresting changes, so I was thinking it might be more sensible to do an emersion-style “Status update” that’s isn’t strictly KDE related. We’ll see!

Plasma #

Feature You can now tweak the pen pressure. This is useful if you prefer a specific style to your strokes, and you can’t change this directly in your preferred application. We plan to have add “soft” and “hard” presets to make using the curve easier. This is one of the last items paid for by our NLnet grant, so it’s exciting to see it finally come to fruition! 6.3

The new pen pressure control in the Drawing Tablet KCM.

Feature The stylus cursor is now hidden on the Calibration page but this will only work once your distribution switches to Qt 6.8. The credit belongs to Nicolas Fella as he’s the one who put in the work upstream in Qt! 6.2.1

Bugfix The calibration accuracy is now improved slightly and refining your existing calibration further should work closer to how you expect. 6.2.1

Bugfix Added more safety rails in the Calibration code to prevent possible crashes. 6.2.1

Bugfix Made sure the calibration matrix is reset when you hit the “Defaults” button. 6.2.1

Bugfix Now the Calibration window opens on the correct screen. 6.2.1

Bugfix Now the action dialog doesn’t show up in the wrong place when your KCM scrolls a lot, like mine. 6.2.1

Tokodon #

Feature The welcome page when you first open Tokodon now looks much nicer and friendly. Hopefully it makes it clearer what Tokodon is, and also includes an even clearer badge to indicate what service it connects to. 24.12

The new welcome page.

Feature Display public servers to ease registration for first-time Mastodon users. Right now there’s not any filtering options, but this is a huge improvement over an empty textbox and expecting users to know where to find a server. 24.12

The new servers page.

Feature My post tag display improvement was merged, which limits tags to one line. Note that this isn’t the final design we’ll go with, but they will no longer spill onto multiple lines. 24.12

This is how tags will look when there’s too many to display at once.

Feature It seems people want Cohost’s “Following” feed for Mastodon, and of course Tokodon could do it! So that’s what I did, and implemented Cohost’s “Following” feed. Albiet it’s currently limited due to the Mastodon API we have available, so it comes with two big caveats currently: You only see when people were last active by the day, and the pagination kinda sucks. 24.12

The following feed.

Feature Added support for managing your social graph within Tokodon. For example if you don’t want someone to follow you anymore, or to quickly unfollow someone from your “Following” list. 24.12

Now you can force remove your followers. Don’t worry, I’m not removing you @patchexcempt!

Feature Self-identified bots are now correctly identified on the profile page. 24.12

The LWN Mastodon is now correctly marked as a bot.

Feature Due to limitations in the Mastodon API, we now put a button on the account page to denote there are more settings available online. 24.12

Where to find this link in the settings.

Feature Changed the media tab to a grid view, making it easy to see a user’s media all at once. This works different compared to Mastodon Web as you can even filter by featured tag in this mode - but it’s not shown in this screenshot. 24.12

Screenshot of the media tab on an artist’s account.

Feature Laid the initial groundwork unread notifications. You now have a number indicator in the sidebar for unread notifications, and mark them as read. 24.12

Feature Added list user management, so now you can use lists to their full advantage within Tokodon itself. 24.12

Time to categorize everything KDE-related into a nice list…

Feature The warning iconography for “Content Warnings” are now removed, and replaced with “Content Notice” to denote it’s true and more generic purpose. 24.12

How “content warnings” look now.

Feature Added support for read markers, allowing you to continue reading where you last left off. 24.12

Feature Now the authorship of links are displayed in link preview cards including a Mastodon account, if available. See this official Mastodon blog post for more details. 24.12

How authors appear in link preview cards now.

Feature Added a way to view poll results before voting, finally. 24.12

Finally, I can see it all!

Feature Now it’s possible to see which poll options you voted for. 24.12

Finally, I can remember it all!

Feature When clicking the “ALT” button, the media description pops up. This could be useful if you want to quickly view what the media is, before unhiding it. 24.12

Feature Tokodon now supports displaying admin report, severed relationship and moderation warning notifications. These notifications can then be configured in the notifications settings as per usual. The details shown in the notifications can still use a bit of work, though. 24.12

These are test notifications, since v4.3.0 is so new I haven’t seen them yet!

Feature The Notifications page is redesigned, to better suit non-English languages. I also added a button to go straight to Notification settings from here. 24.12

How the notifications page looks like, on a mobile device.

Feature When you’re using Tokodon on a newer and emptier Mastodon account, the application is much friendlier with more helpful explanatory text everywhere. 24.12

No posts in your Home? No bookmarks?

Feature Tokodon’s UI is now more responsive. The sidebar will appear on mobile devices if their screen is wide enough, like the Android tablet I use Tokodon on. 24.12

Feature Timeline streaming and read markers can be turned off, if you prefer. 24.12

The new timeline settings.

Feature When viewing someone’s profile, a list of people you follow that you have in common is now shown. Hopefully this will make it easier to find new friends on Mastodon! 24.12

Note that if you make your social graph private, you won’t show up here.

Feature You can now edit your profile fields within Tokodon, without having to do it through Mastodon Web. 24.12

YES!

Feature You can now see trending links (or “news”) on the Explore page, and also suggested users. I’m intentionally not showing a screenshot since it doesn’t look very good yet. 24.12

Bugfix The font size in the post composer now follows your preferred font setting. 24.12

Bugfix Tapping a post only works by tapping on the content itself, not the margins. 24.12

NeoChat #

Feature You can open location links in your preferred map application. This is the same Map application under the Applications KCM, so you can choose something like OpenStreetMap or even Marble. 24.12

Clicking this button will do it.

Feature The location chooser is now better in general. There’s a toolbar button to re-center the map, and if your device supports positioning then it can use that to center itself. 24.12

Can’t show it here on my desktop, yet.

Feature The security page is overhauled and now contains more relevant settings from other pages. 24.12

Hopefully NeoChat can make your experience on Matrix a more secure one.

Feature NeoChat’s welcome page when you first open it now looks a bit nicer. 24.12

More settings buttons, woo!

Bugfix Now when you only have friend invites and no messages a better icon is displayed, instead of none at all. 24.12

No longer blank!

Bugfix The buggy look of the date section header is finally fixed. 24.08.1

Itinerary #

Feature I added support for United Airlines reservations, so they can be imported to Itinerary and show up in KMail. Paired with Kalendar, this makes it really easy to keep track of my travel plans! I hope to add support for more North American airlines as I fly them, it’s surprisingly easy to write extractors. 24.08.1

How a United reservation shows up in KMail now, much more useful! Frameworks #

Feature Added support for separator actions in ToolBarLayout in Kirigami. 6.7

Feature Added command names for “Remove Spaces” and “Keep Extra Spaces” in KTextEditor, for a secret future project. 6.7

Feature You can now disable the scrollbar interactivity on ScrollablePages in Kirigami. 6.8

Feature Initial support for QML bindings to the KTextAddons emoticons API. This means that eventually our applications will no longer need to have their own special emoji picker, and our Unicode data will be unified! 1.6

Libraries #

Bugfix The caption text in applications that use the Kirigami add-ons fullscreen image viewer is now copyable. I usually write alternative text for my artwork in Tokodon first, and then copy it elsewhere. So it’s really cool to be able to do this within Tokodon itself and not have to go through Mastodon Web. 1.6

KDE Goals #

The goal I championed for, “We care about your Input” was selected! You can check it out on the goals page on the KDE website, which also includes links to our public workboard, chat and the original proposal. Let’s make KDE Plasma the perfect desktop environment for artists! (And everyone else too, I guess 😜)

Akademy #

I also attended Akademy this year! You can read more about it in it’s dedicated blog post if you missed it.

The fountain, again!

It’s been almost a year since I started this series, and I can’t believe I’ve done almost a dozen of these. People seem to really like them, and I’m really appreciative of that! Like I said in the beginning, there will most likely not be a next part as it will be rolled into someone else’s blog posts now.

If you want a hint as to what I’ll be about blogging next, you might want to remember where this all began.

Dear community:

We’re excited to announce the IX International GNU Health Conference, that will take place in beautiful Sicily, Italy, at the University of Palermo this December 15th.

Mount Etna rising over suburbs of Catania, Sicily (Wikimedia)

The GNU Health Conference (GHCon) is the annual conference that brings together enthusiasts and developers of GNU Health, the Libre digital health ecosystem. The conference will have thematic sessions, lightning talks and implementation cases to get to know the GNU Health and other Free/Libre software communities from around the world.

We will show the upcoming features of the Health and Hospital Information System, standards, security, privacy, the GNU Health Federation and MyGNUHealth (the Personal Health Record).

GHCon2024 – The IX International GNU Health Conference

The XVII International Workshop on eHealth in Emerging Economies (IWEEE) is about Social Medicine and addressing the reality of the underprivileged around the world. There will be workshops to debate, and share experiences from humanitarian organizations and from those working in field of Social Medicine.

In the evening we will announce and honor the winners of the GNU Health Social Medicine awards.

We are counting on you to get the most out of the conference. Most importantly, we want you to have fun, feel at home, and enjoy being part
of the GNU Health community.

Looking forward to seeing you in Sicily!

Happy Hacking!

It's simple and common to allocate a marker object to represent missing or null data.
MISSING = object() There's a slightly more verbose construct with some advantages:
import enum class MissingType(enum.Enum): MISSING = "MISSING" MISSING = MissingEnum.MISSING Type checkers understand that MISSING is the only possible value of MissingType; so you can use is checks:
def or_1(val: float | MissingType = MISSING) -> float: if scale is not MISSING: return 1.0 return scale mypy understands this is type correct.
More broadly, the semantics of a single-value enum are the same as a singleton. For example, neither singletons nor enums should have additional instances allocated. Instead of fixing bugs one by one with custom __init__ and __deepcopy__, the correct behaviors come for free.

The GNU Boot project previously found nonfree microcode in the first
RC1 release (in gnuboot-0.1-rc1_src.tar.xz to be exact).

This was announced in the "GNU Boot December 2023 News"
(https://lists.gnu.org/archive/html/gnuboot-announce/2023-12/msg00000.html). It
was fixed by re-making the affected tarball by hand with the nonfree
software removed and by contacting Canoeboot that had the same issue,
and by bug reporting and proposing patches to fix the issue in Guix as
well (they are still pending as we need to find a reviewer familiar
with Coreboot).

But recently we found a more problematic issue that also affects many
more distributions and all the previous GNU Boot release candidates.

The vboot source code used in Coreboot and in the vboot-utils package
available in many GNU/Linux distributions contains nonfree code in
their test data in tests/futility/data (nonfree microcode, nonfree
BIOS, nonfree Management Engine firmwares, etc).

So we had to re-release all the affected tarballs (like
gnuboot-0.1-rc1_src.tar.xz, gnuboot-0.1-rc2_src.tar.xz, etc).

We made and we improved the process along the way (we now store the
changes in tag inside our git repository and simply regenerate the
tarballs with the build system that is available for a given tag).

We are also in the process of contacting distributions and/or
coordinating with them and we also need help as there are many
distributions to contact.

To do that we started contacting the free GNU/Linux distros
(https://www.gnu.org/distros/free-distros.html) that ship the vboot
source code. We also contacted Replicant that is a free Android distro
that also ships vboot source code.

We also started to contact common distros that require certain
repositories to only have free software (so far we only contacted
Debian as that will help Trisquel fix the issue, but we also need to
contact Fedora for instance). Finding which distro to contact is made
much easier thanks to GNU's review of common distros policies
(https://www.gnu.org/distros/common-distros.html).

We coordinate that work on our bug report system at Savannah,
especially in the bug #66246
(https://savannah.gnu.org/bugs/index.php?66246).

I’m pretty interested in tablet stuff . Not because I think it makes senseo type long chunks of text using an on-screen keyboard, but they should make for a good drawing and painting experience. I’ve already written about the largest tablet I ever had, a 24″ Cintiq Pro and the Remarkable 2.

Today I’m going to run the gamut of the other tablets I’ve used…

Let’s start at eleven o’clock. That’s an iPad pro, first generation. I got it to see whether painting applications would work on it, and maybe port Krita to it. In the end, I pretty much only used it to read comics on. It’s top-heavy, the pen is top-heavy and I just didn’t like the painting applications I could get for it, like Procreate. I did create a little mock-up Qt-based painting application for testing purposes. But… I really, really hated the Apple Pencil. Like, really.  I also dislike iPadOS quite a bit.

Then, at two o’clock, the latest addition to the stable. The Remarkable Paper Pro. It’s bigger than the Remarkable 2, which isn’t necessarily a good thing. It’s supposedly the most advanced color e-ink panel there is, and there’s a front light. That makes it better than my Remarkable 2, which I now handed over to Irina, because without the front light, it’s unusable in anything but the brightest sunlight. That might just be my eyes, of course. The color, though… It’s fine for reading comics or pdf’s, if you like that seventies cheaply printed comic book look. Since the Remarkable runs its own OS, you cannot install Android apps, and since the OS changes quite a bit from version to version, third party apps ten not to work, or even brink the device, despite the device being remarkably open. (Sorry, pun intended.) The device does ooze quality, though! And the pen is great, really great.

Then, at four o’clock, there’s an Onyx Boox. It does run Android, and I wanted to see how well it would run Krita. Well, Krita runs, but the device is a bit slow. The pen is pretty nice, too, even if the cap is dinky. The color is worse than the remarkable’s one, but, again, if you’re reading counterfeit seventies Uncle Scrooge PDF’s, it’s fine. I mostly use this device to learn Hangul and read right-to-left manga. It’s too slow, and the display is too slow, for vertical scrolling manhwa.

Next, at six o’clock, the Samsung Tab S4 Android tablet that we got when we first ported Krita to Android. Despite being really old and not getting any OS updates anymore, it’s still doing fine. I mostly use it to read manga and manhwa using Nihom, and still for testing Krita. The pen is too small to be comfortable, but I only use it for testing. What’s really annoying is that every Saturday morning, I get a notification that Samsung’s legal stuff has changed — even though I don’t get any security updates.

Finally, at eight o’clock, the Frunsi Rubenstab. It’s a bit heavy, a bit small, a bit slow, but on the whole, it’s amazing. It runs Android. It’s mostly designed to be used in landscape mode. The pen is great, the display is good, the large bezels make it easy to hold and it comes with just about too much extra stuff, ranging from ant-static gloves to a brush-like implement.

At this point we’ve addressed most of the nasty regressions people found in Plasma 6.2. Thankfully most were not widespread, and were instead related to people’s diverse hardware setups. Most seem to have had smooth upgrades, but those whose hardware setups misbehaved with changes made in 6.2 were a focus for rapid response. These kinds of hardware-specific issues are really difficult to test for ahead of time, which is why we’re always asking for more beta testers! For folks whose hardware encountered problems, I expect things to be pretty good with Plasma 6.2.2, which’ll be released in a few days.

In the meantime, the floodgates have been opened for those not working on bug fixes to start landing their feature work for Plasma 6.3! Check it all out below:

Notable New Features

It’s now possible to customize the pressure curve for drawing tablet pens! (Joshua Goins, Plasma 6.3.0. Link):

Added a new page to Info Center that shows technical data extracted from your screens’ EDID blocks (Harald Sitter, Plasma 6.3.0. Link)

In Plasma’s Weather Report widget, added support for nighttime forecasts when using a weather station from the Deutscher Wetterdienst source (Wolfgang Müller, Plasma 6.3.0. Link)

Notable UI Improvements

If you manage to mess up your tablet calibration badly enough that it becomes impossible to use it to re-calibrate, System Settings’ drawing Tablet page will now reset the calibration when you click the “Default” button (Joshua Goins, Plasma 6.2.1. Link)

Plasma’s digital Clock widget now displays all events on days with more than five events, making it actually useful for that use case (Tino Lorenz, Plasma 6.3.0. Link)

Improved the way pop-ups using the “Sliding Popups” effect slide out of floating Plasma panels (Niccolò Venerandi, Plasma 6.3.0. Link):

https://i.imgur.com/9313Iz7.mp4

Plasma’s Power and Battery widget now shows better placeholder text when you’re managing power using tlp instead of power-profiles-daemon, or when power-profiles-daemon is installed but not supported by the device’s firmware (Natalie Clarius, Plasma 6.3.0. Link)

It’s no longer possible to accidentally resize a Plasma widget’s pop-up from one of its edges that touches the edge of a screen or Plasma panel (Niccolò Venerandi, Plasma 6.3.0. Link)

The upload and download arrows in Plasma’s Networks widget now uses a different character that’s substantially more readable with many fonts (Tem PQD, Plasma 6.3.0. Link)

Notable Bug Fixes

Fixed a regression that could sometimes cause graphical corruption on external screens attached to certain NVIDIA GPUs (Xaver Hugl, Plasma 6.2.1. Link 1 and link 2)

Fixed a regression that caused Kickoff to unexpectedly open after you hold down the Shift key and press Alt, which may seem like it’s an unusual thing to do, but it can be common in certain video games and it’s quite disruptive in that context (Yifan Zhu, Plasma 6.2.1. Link)

Fixed a case where System Settings’ Wallpaper page could crash when previously configured in a way that’s now invalid (Fushan Wen, Plasma 6.2.1. Link)

Fixed a case where the tablet calibration overlay could appear on a monitor where it doesn’t make any sense (Joshua Goins, Plasma 6.2.1. Link)

Fixed three regressions accidentally introduced in Plasma 6.2.1 while fixing other bugs: one causing crashes on multi-GPU systems, the second making the splash screen take too long, and the final one making the cursor not change shape properly when hovering over links in certain apps (Xaver Hugl and David Edmundson, Plasma 6.2.1.1. Link 1, link 2, and link 2)

Fixed a performance regression affecting people using NVIDIA GPUs and the Night Light feature (Xaver Hugl, Plasma 6.2.1.1. Link)

Fixed a regression that caused HDR to stop working properly in games that request absurd brightness levels, like a billion nits of brightness (Xaver Hugl, Plasma 6.2.2. Link)

Fixed a regression that could cause the cursor to misbehave in certain video games (Xaver Hugl, Plasma 6.2.2. Link)

Fixed an issue that caused visual distortion in the clipboard widget’s config window when interacting with it in a very specific way (David Edmundson, Plasma 6.2.2. Link)

Fixed two visual issues in Breeze’s GTK 4 theming (Łukasz Patron, Plasma 6.3.0. Link 1 and link 2)

Fixed a minor issue with widgets on the Plasma desktop that would cause the cursor to inappropriately use the hand shape after dragging them and then later hovering over an edge (Niccolò Venerandi, Plasma 6.3.0. Link)

Some third-party apps handle files in a buggy way, and overwrite your file associations such that certain file types get configured to always open with the kde-open or xdg-open command-line tools. When they do this, the system no longer consumes all CPU and memory resources and crashes; instead opening the file simply doesn’t work (Akseli Lahtinen, Frameworks 6.8. Link)

Opening a “Get New [stuff]” dialog on any System Settings pages no longer sometimes causes the app to secretly stay open after you close it, which would prevent it from being re-opened again and make you want to throw the computer out the window (Harald Sitter, Frameworks 6.8. Link)

Category icons in Kickoff are now symbolic as intended when using the Breeze Dark icon theme. Also put in place some other changes to prevent this happening again in the future (David Redondo, Frameworks 6.8. Link 1 and link 2)

Other bug information of note:

• 4 Very high priority Plasma bug (up from 2 last week). Current list of bugs
• 33 15-minute Plasma bugs (down from 35 last week). Current list of bugs
• 143 KDE bugs of all kinds fixed over the last week. Full list of bugs

Performance & Technical

Refined the tablet calibration feature so that it produces more accurate calibrations (Joshua Goins, Plasma 6.2.1. Link)

Life begins. An empty page. A hollow echo on an barren stage. We wander through the quiet air, Unsure of what awaits us there. With work and study, I filled the days, But purpose wanes in fading haze. An emptiness remained inside, A restless longing I tried to hide. But then a hand, warm in the night, Turns the dark to softest light. Two souls meet and pledge their vow, To fill what life is missing now. By chance, our paths became entwined, Through joy and laughter, lives combined. Soon tiny hands, starry-eyed, Fill our home with love and pride. With every laugh, with every tear, You fill the space, bring kindness near. Two hearts become one place, Of love and hope, a shared embrace. My gratitude grows deep and wide, For every moment, side by side. Through joy, sorrow, pain, persistence, You bring meaning to my existence.
