At this years Debian conference in South Korea I've presented1 the new feature of the FAIme web service. You can now build your own Debian live media/ISO.

The web interface provides various settings, for e.g. adding a user name and its password, selecting the Debian release (stable or testing), the desktop environment and the language. Additionally you can add your own list of packages, that will be installed into the live environment. It's possible to define a custom script that gets executed during the boot process. For remote access to the live system, you can easily sepcify a github, gitlab or salsa account, whose public ssh key will be used for passwordless root access. If your hardware needs special grub settings, you may also add those. I'm thinking about adding an autologin checkbox, so the live media could be used for a kiosk system.

And finally newer hardware is supported with the help of the backports kernel for the Debian stable release (aka bookworm). This combination is not available from the official Debian live images or the netinst media because the later has some complicated dependencies which are not that easy to resolve2. At DebConf24 I've talked to Alper who has some ideas3 how to improve the Debian installer environment which then may support a backports kernel.

The FAI web service for live ISO is available at

2024 Minnesota State Fair foods About • Blog • Newsletter • Links 2024 Minnesota State Fair foods

Published 2024-08-25 by Seth Larson
Reading time: minutes

If you didn't know, I'm from Minnesota. Minnesotans love their State Fair, and I'm not an exception! My wife and I were lucky enough to go to a State Fair preview for LuLu's Public House for fried ranch dressing among a handful of new drinks. I shared my thoughts on Mastodon and a few folks seemed interested in hearing more: so here's more!

Cajun fried pickles from The Perfect Pickle

These are hands-down the best food at the Minnesota State Fair. You eat an order, ponder getting more (some years we do!) and then wonder to yourself why they put the best of the best right next to the shuttle entrance. Don't go out looking for answers lest they move these further away, sometimes it's best to leave sleeping “pickle dogs” lie.

Seriously, if you like pickles even a little bit, get these pickles. You can get them quick if you're lucky and other folks don't realize there are supposed to be six lines of people taking orders.

They're ripping hot right when they hand them to you, so if you're like me and enjoy food “biting back” then don't delay! 🔥

This year included a noticeable increase in the amount of Cajun seasoning, or we got lucky and someone behind the scenes gave us an extra coating (either way we're not complaining!)

Peanut Butter Bacon Cakes and Blue Cheese & Corn Fritz from The Blue Barn

Celebrating their 10th consecutive year at the Minnesota State Fair, The Blue Barn is always a fan favorite. Seriously, run over there if you get to the fair early to beat the massive lines for food and drinks.

We grabbed the new Peanut Butter Bacon Cakes along with the returning classic Blue Cheese & Corn Fritz which I had never tried before.

The Peanut Butter Bacon Cakes were really great, there was thick-cut bacon griddled inside of pancake batter strips along with jelly and a peanut butter whipped cream. Perfect combo of savory and sweet, and you're in complete control of the ratios. The bacon and pancake flavors reminded me of learning to make pancakes with my late grandfather. Although that bacon was microwave-ready Hormel bacon... I promise this one's delish!

The Blue Cheese & Corn Fritz was really great, I missed out on this one last year. Perfect amount of sweetness from the corn, really well-balanced cheesy little bite! Wish I could have had more than one of these, we were sharing amongst a big group!

Wrangler Waffle Burger, Bacon-Wrapped Pickle Dog, and “Kind of a Big Dill” Lemonade from Nordic Waffles

Another vendor that fills up immediately after opening, Nordic Waffle should be top of your list because of two returning new foods from 2023: the Bacon-Wrapped Pickle Dog and the Pickle Lemonade. Both of these are really great, the lemonade sounds strange but works really well (even if you don't love pickles). The subtle saltiness balances out the sweet and tartness which makes for a dangerously drinkable item.

The Wrangler was good, it's one of those winning combinations of flavors that is really hard to mess up: beef, cheese, caramelized onions, and a mayo-based sauce. The onions being grilled into the waffle was fun but didn't do much flavor-wise (they might as well have been a topping), honestly wish they went all-out on the onions to the point of being noticeable texture-wise in the waffle. The bacon-wrapped pickle dog is as awesome as it sounds, so much more interesting flavor-wise!

I'm also not a fan of their choice of sauce, they went with Whataburger, a famously mid-tier burger joint in Texas, of all places? This is a grave error by Nordic Waffles because Minnesota and Texas have serious State Fair beef. Minnesota seeing the highest single-day attendance over 12 days, where the Texas State Fair sees the highest total attendance over 24 days (it might be obvious which State Fair I think is the true champion).

Sweet Corn Cola Float from Blue Moon Dine-in Theater

This one was interesting! Sweet Corn icecream and house-made “corn Cola”, so I take that to mean corn syrup Cola? Not sure. The flavor definitely gave a “not-too-sweet” vibe which was nice, there was a good amount of a corny and almost “earthy” flavor in the float.

The texture of the corn icecream was a little less smooth than a normal icecream, which landed somewhere between novel and “interesting”. I actually recommend giving this one a good mix before you drink it to blend the flavors together better, you're only given a boba straw to drink it.

Overall, would I get it again? Probably not, because Lift Bridge root beer floats exist and are much better. But worth a try!

Sweet Heat Bacon Crunch from RC's BBQ

Had this one side-by-side with my typical order from RC's which is a bunch of ribs and yeah, it was fine, but if I'm buying barbecue I want ribs or brisket. There was some chili crisp (but not much, maybe because it's Minnesota) and hot honey that got a bit lost in the dish. Can't recommend this one, RC's usual items are much better.

Spam breakfast sandwich from SPAM

Attention all SPAM-lovers at the fair! The SPAM booth has moved from under the Grandstand bridge to the southern edge of the DNR building. I nearly had a heart-attack when I saw the SPAM booth wasn't in its usual spot, I had to sneak away with a fellow SPAM-lover from our group to snag this item.

We got ours with pickles (surprise!) and jalapeños, a little bit of kick and acid to cut through the lovely fatty grilled SPAM. Pretty sure this little sandwich was gone in 4 bites, highly recommend finding this stand if you're a long-time-enjoyer or first-timer of SPAM!

That's all for this year. At this point we kept trying new items, but I suspect not being hungry started to impact my opinions of the foods, so you'll have to try them yourself! :)

GSoC Work Product: GNUnet over HTTP/3 Goals of the Project.

This project aimed to implement a new communicator for GNUnet's Transport Next Generation (TNG) using the HTTP/3 protocol.

What I did.

We chose ngtcp2 and nghttp3 for their stability and adherence to RFC standards. I began by studying communicator fundamentals and analyzing relevant code examples. I then created a QUIC communicator using libngtcp2, implementing essential communication features. Building on this, I integrated libnghttp3 to support HTTP/3 layer communication. After establishing basic uni-directional communication, I proceeded to implement bi-directional capabilities. With the help and guidance of my mentors, I completed the above work, including the selection and design of message transmission methods and the implementation of code.

The current state.

We have two branches, dev/shichao/http3 for basic communication and dev/shichao/http3bidirect for bi-directional communication. They can pass the basic tests. However, we found that there were occasional failures during the test. We currently assume that this is caused by the test harness not being able to process the received data packets in time.

What's left to do.

There are still many areas that can be improved in the HTTP/3 communicator, such as using CID map instead of IP address map. In addition, in bi-directional communication, the server's sending rate is slightly lower than the client's transmission rate, and this will be optimized in the future. Finally, integrating the Peer Identity into the TLS handshake in order to authenticate the peers is a natural feature to implement.

What code got merged (or not) upstream.

All the code is available upstream in the master branch and will be available with the next release.

Challenges I Encountered.

Initially, I was unfamiliar with the ngtcp2 and nghttp3 libraries. While there were some examples available, I found limited guidance for more advanced usage. Through careful study and experimentation, I gradually gained a deeper understanding of these libraries. But in this process, I have a deeper understanding of QUIC and HTTP/3 protocols, and also improved my coding skills.

A new maintenance release of RcppEigen is now on CRAN, and will go to Debian shortly as usual. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms. RcppEigen is used by 460 other CRAN packages, and has been downloaded 31.9 million times just off the mirrors of CRAN keeping logs for counting.

The recent change switing to Authors@R (now that CRAN mandates it) contained in dual typo in ORCID tags, this releases fixes it.

The complete NEWS file entry follows.

Changes in RcppEigen version 0.3.4.0.2 (2024-08-23)

• Correct two typos in the ORCID tag

Courtesy of CRANberries, there is also a diffstat report for the most recent release.

I am looking into getting a Wifi mesh network. The aim is to use it for providing access to devices through my home especially for devices on the congested 2.4GHz frequency. Ideally I want 6GHz Wifi6E for the communication between mesh nodes as well as for talking to the few devices that are new enough to support it (I like buying cheap second hand devices). 2.5Gbit ethernet connections on all mesh nodes would be good too.

Wifi 7 is semi-released, you can buy devices even though the specs aren’t entirely finalised. I expect that next year when Wifi 7 devices are more common the second hand prices of Wifi 6E will drop. Currently Wifi 6E devices are somewhat expensive.

One major problem at the moment is “cloud configuration”. Here is a 41 page forum thread of TP-Link customers asking in vain for non-cloud configuration [1]. The problems with cloud configuration are that it doesn’t allow configuration without Internet access (so no fixing things when internet breaks and no use for a private network without Internet), it relies on a proprietary phone app (so a problem with your phone breaks everything), and it adds a dependency on an unpaid service that TP-Link might decide to turn off at some future time. The TP -Link Deco X55 AX3000 looks like a good set of devices, it currently costs $328 for a set of three Wifi 6 (not 6E) devices is a good deal, pity that the poor software options let it down.

TP-Link also seems to be scanning web traffic and sending the analysis to an external site [2], it seems to be operating as malware. The TP-Link software seems to be most accurately described as malware.

There is the OpenWrt project for open firmware on Wifi APs which is a great project [3] but it doesn’t seem to support any Wifi 6 mesh systems yet. If most Wifi hardware requires malware for operation it seems that running a VPN over Wifi is the way to go. A hostile party being able to sniff your home network is much worse than a hostile party sniffing public Internet traffic.

The Google Nest mesh devices have good specs and price, $359 for a three node Wifi 6E mesh that has 2.5Gbit ethernet. But they can only be configured with a Google app for Android or iOS and require a Gmail account. Giving Google the ability to shut down all my stuff by deleting my gmail account is not acceptable. Also Google is well known for cancelling services [4]. A mitigating factor is that there should be enough of those devices sold to make them a good target for an OpenWRT port.

As an aside it looks like the TailScale mesh VPN system could be a solution to the security issues related to malware on Wifi APs problem [5]. There is also HeadScale which is the fully open source variant of that [6]. Even when the vendor isn’t overtly hostile they can make mistakes so encryption is good.

Kogan is selling an own-brand Wifi 6 mesh network package that comes with 1/2/3 devices for $70/$120/$140. It doesn’t do Wifi 6E but supports the better encoding methods of Wifi 6 over Wifi 5 and will be good for bridging a LAN in one part of a house to a Wifi 2.4GHz or Ethernet connected device in another part. They also support up to 7 nodes so you could buy two of the 3 device packages and run one network with 2 and another with 4. The pricing is very competitive and they support web based administration!

I’ve just ordered the $140 pack from Kogan. If it doesn’t do what I want then I can find someone else who will be happy with whatever functionality it gives and $140 is an amount I can risk without concern. If it works well then I might upgrade to Wifi 6E or Wifi 7 next year and deploy the Wifi 6 one for a relative.

With news like this one cited by Bruce Schneier [1] people are asking whether it’s worth using Secure Boot.

Regarding the specific news article, this is always a risk with distributed public key encryption systems. Lose control of one private key and attackers can do bad things. That doesn’t make it bad it just makes it less valuable. If you want to setup a system for a government agency, bank, or other high value target then it’s quite reasonable to expect an adversary to purchase systems of the same make and model to verify that their attacks will work. If you want to make your home PC a little harder to attack then you can expect that the likely adversaries won’t bother with such things. You don’t need security to be perfect, making a particular attack slightly more difficult than other potential attacks gives a large part of the benefit.

The purpose of Secure Boot is to verify the boot loader with a public key signature and then have the boot loader verify the kernel. Microsoft signs the “shim” that is used by each Linux distribution to load GRUB (or another boot loader). So when I configure a Debian system with Secure Boot enabled that doesn’t stop anyone from booting Ubuntu. From the signatures on the boot loader etc there is no difference from my Debian installation and a rescue image from Debian, Ubuntu, or another distribution booted by a hostile party to do things against my interests. The difference between the legitimate OS image and malware is a matter of who boots it and the reason for booting it.

It is possible to deconfigure Microsoft keys from UEFI to only boot from your own key, this document describes what is necessary to do that [2]. Basically if you boot without using any “option ROMs” (which among other things means the ROM from your video card) then you can disable the MS keys.

If it’s impossible to disable the MS keys that doesn’t make it impossible to gain a benefit from the Secure Boot process. You can use a block device decryption process that involves a signature of the kernel and the BIOS being used as part of the decryption for the device. So if a system is booted with the wrong kernel and the user doesn’t recognise it then they will find that they can’t unlock the device with the password. I think it’s possible on some systems to run the Secure Boot functionality in a non-enforcing mode such that it will use a bootloader without a valid signature but still use the hash for TPM calculations, that appears impossible on my Thinkpad Yoga Gen3 which only has enabled and disabled as options but should work on Dell laptops which have an option to run Secure Boot in permissive mode.

I believe that the way of the future is to use something like EFIStub [3] to create unified kernel images with a signed kernel, initrd, and command-line parameters in a single bundle which can be loaded directly by the UEFI BIOS. From the perspective of a distribution developer it’s good to have many people using the current standard functionality of shim and GRUB for EFI as a step towards that goal.

CloudFlare has a good blog post about Linux kernel hardening [4]. In that post they cover the benefits of a full secure boot setup (which is difficult at the current time) and the way that secure boot enables the lockdown module for kernel integrity. When Secure Boot is detected by the kernel it automatically enables lockdown=integrity functionality (see this blog post for an explanation of lockdown [5]). It is possible to enable this by putting “lockdown=integrity” on the kernel command line or “lockdown=confidentiality” if you want even more protection, but it happens by default with Secure Boot. Secure Boot is something you can set to get a selection of security features enabled and get a known minimum level of integrity even if the signatures aren’t used for anything useful, restricting a system to only boot kernels from MS, Debian, Ubuntu, Red Hat, etc is not useful.

For most users I think that Secure Boot is a small increase in security but testing it on a large number of systems allows increasing the overall security of operating systems which benefits the world. Also I think that having features like EFIStub usable for a large portion of the users (possibly the majority of users) is something that can be expected to happen in the lifetime of hardware being purchased now. So ensuring that Secure Boot works with GRUB now will facilitate using EFIStub etc in future years.

The Secure Boot page on the Debian wiki is worth reading, and also worth updating for people who want to contribute [6].

This week was all about the quality of life features! As we close in on Plasma 6.2 (the soft feature freeze is in four days, eek!), some great work that’s been in progress for a long time got merged.

Notable New Features

Okular now has a “speak text from current page” feature (Athul Raj Kollareth, Okular 24.12.0. Link)

Plasma’s Brightness widget now shows individual brightness sliders for every connected monitor that supports this, so you can control them separately! If you want to adjust all of them together, you can still do that via global shortcut/keyboard key or by scrolling over the widget (Jakob Petsovits, Plasma 6.2.0. Link):

When there’s a pending offline system update, you’ve already got the option to update and then reboot, or just reboot and skip the update. Now, there’s also an option to complete the update and then shut down the computer! This option is exposed both on the logout screen, and also in Discover (Thomas Duckworth, Plasma 6.2.0. Link 1, link 2, and link 3):

Long-pressing an empty area of a Plasma panel using a touchscreen now enters edit mode for that panel (Niccolò Venerandi, Plasma 6.2.0. Link)

Notable UI Improvements

The “Add Widgets” sidebar has received a UX overhaul with numerous usability focused changes, including:

• Appearing on the right side of the screen when opened from a right-screen-edge panel
• Using wider grid cells to permit longer text without elision or unnatural word-wrap behaviors
• Improved appearance of the filter button, so now it looks like it opens a drop-down menu — because it does
• Sorting is now locale-aware, taking into account, for example, accented characters
• You access it from buttons and menu items labeled “Add or Manage Widgets,” since it also acts as the place where you get new widgets or delete unwanted ones
• Spacer widgets can also be found there, no longer only from the panel settings dialog
• When installing manually-downloaded widgets, the open dialog now accept all valid file types

And believe it or not, that’s not all that’s planned! But the rest will have to wait until next week… (Niccolò Venerandi, Plasma 6.2.0. Link 1, link 2 3, link 4, link 5, link 6, link 7)

When your system is using a non-default power profile, it’s now shown as a badge on the battery icon, so you can see both the power profile and also the battery status at the same time (Louis Moureaux and me: Nate Graham, Plasma 6.2.0. Link 1 and link 2):

At the moment this only works with the Breeze icon theme, and 3rd-party icon themes will have to add some more icons to opt into it. Until then, users of those icon themes will get the old appearance when using a non-default power profile

A panel popup opened from a widget on the end of a limited-width panel now tries its best to align its edge with that of the panel (Niccolò Venerandi, Plasma 6.2.0. Link):

Maybe I just really like clocks, ok?

You can now give a custom display name to your custom command shortcuts (Yifan Zhu and Thenujan Sandramohan, Plasma 6.2.0. Link):

Discover is now more accurate about how it presents licenses, and communicates the subtle distinctions between “proprietary” and “non-free”, rather than branding everything that isn’t free software as proprietary (me: Nate Graham, Plasma 6.2.0. Link):

When you change keyboard layouts, the labels of the language codes that appear in the system tray no longer subtly change in size based on the shape of their letters (Sauf Lvc, Plasma 6.2.0. Link)

Added a Breeze icon for Applet Wallet bundle files (Kai Uwe Broulik, Frameworks 6.6. Link):

Notable Bug Fixes

When Spectacle is configured to save in a format other than PNG by default, pasting a just-copied screenshot now always works in every target app, with the caveat that some apps that don’t advertise support for non-PNG image pasting (like Firefox and Chromium, annoyingly) will get a PNG version anyway, rather than your preferred file format. This is better than it not working at all, at least! (Noah Davis, Spectacle 24.08.1. Link)

You can once again use the arrow keys to move focus out of Kickoff’s favorites grid view (Arjen Hiemstra, Plasma 6.1.5. Link)

Fixed a complex bug that could cause KWin to crash when X11 or XWayland-using apps monkeyed with the window stacking order in specific ways (Vlad Zahorodnii, Plasma 6.1.5. Link. And thanks to the reporter Peter Strick for being incredibly helpful in making the issue reproducible! All bug reports should be so good.)

Fixed an annoying bug that caused text copied from cells in LibreOffice Calc to never make it onto the clipboard unless you changed the clipboard’s settings to always store images (Fushan Wen, Plasma 6.1.5. Link)

Fixed a bug that caused tooltips to appear at the last location the mouse pointer was located at when interacting with the system using a stylus (David Redondo, Plasma 6.1.5. Link)

Fixed a funny bug that could make Plasma crash when you have a Media Player widget on your panel (not the System Tray, directly on a panel) and play certain specific songs whose titles are exactly the right length to trigger an obscure layout bug (Fushan Wen, Plasma 6.2.0. Link)

Fixed a weird issue that made modifier-only global shortcuts in the X11 session fail to switch keyboard layouts as expected while on the lock screen and other places (Yifan Zhu, Plasma 6.2.0. Link)

Exporting your shortcuts on System Settings’ Shortcuts page now includes any custom script shortcuts you’ve created, so that when you import them elsewhere, they work (Akseli Lahtinen and David Redondo, Plasma 6.2.0. Link)

Notable in Performance & Technical

Improved KWin’s HDR tone mapping, allowing it to do a better job of displaying colors in cases where HDR content specifies a brightness level higher than what the screen is capable of outputting. There’s even more that can be done, but it’s already a big improvement. (Xaver Hugl, Plasma 6.2.0. Link)

Even further optimized the system performance impact in KWin of using an ICC profile to change your screen’s color calibration (Xaver Hugl, Plasma 6.2.0. Link)

Improved KWin’s performance for some multi-GPU systems (Xaver Hugl, Plasma 6.2.0. Link)

Added a bunch of autotests for X11-specific behavior in KWin, since fewer people are exercising that code now that 80+% of Plasma 6 users are using Wayland (Vlad Zahorodnii, Plasma 6.2.0. Link)

Unbundling Profile: MIT Libraries - SPARC

Tags: research, copyright, open-access

It’s good to see major institutions like this get out of contracts with scientific publishing companies. Those unfortunately became mostly parasitic. Open access should be the norm for research.

I've been spending some time recently trying to get the Umami demo message from toolbar into the navigation module.

Since Plasma 5.18, nearly five years ago, Plasma has shipped with a "telemetry" system. It’s opt-in, allowing users to send a small amount of data back to us.

Was it useful or worth it? It's a question that comes up occasionally, and the answer is mixed. I believe it showed real potential, though the reality of our implementation was somewhat underwhelming and didn't really deliver. There are many lessons learned that are worth sharing with other projects that might face similar endeavours.

The good bits

Where we had data available for topics being discussed it worked. To give two concrete examples from memory:

• A developer claimed, "No one is using a screen smaller than 1024x768," while bumping the minimum size of a window. This was proved wrong; the number of users at 800x600 or even 640x480 is surprisingly high. Still low as an overall percentage, but higher than you would ever intuitively think. Presumably, it's the default for a lot of virtual machines.

• Four years ago, a developer claimed, "No one still uses only OpenGL2; we can change the code to do XYZ." A check of our user base showed it would have affected nearly 5% of our users, so the change was abandoned.

Interestingly, this last topic came up again very recently, as it held back colour management improvements, but in a narrower Wayland-only path and with a fallback. After checking metrics again, the usage was below 1%, so we went ahead with that merge request.

So, are metrics worth it just to stop developers and designers from making nonsense claims out of thin air? Absolutely! 90% of stats are just made up on the spot. Metrics are just as much about preventing changes as it is about sparking changes.

Indirect impact

The other important part is having a more general sense of the landscape. Currently, we have a lot of hard conversations about how quickly we push the move to Wayland. We have voices wanting to maintain support, and we have voices wanting to push quicker. These decisions shouldn't be made just by who can be the loudest. For every individual topic that came up in those discussions, I would always have in mind our current adoption value at the time.

Should we care about Nvidia? Knowing they make up about 25% of our user base makes the decision for us. I ran with an Nvidia card in one machine because of this, implementing Nvidia context loss handling and doing what we could during the Wayland transition
We don't test BSD while developing Plasma, but we also let it hold us back. Should we care about it more or less? My opinion matches exactly what the metrics say.

Some stats and graphs:

Another role of metrics is being a conversation starter—people will fawn over a graph. More topics on Reddit will be about our Wayland usage rather than the topic I'm trying to discuss. I'll focus on Wayland examples beacuse that's a topic close to me.

Wayland adoption over time

I keep tabs on what our metrics show here. We can see the slow increase from under 20% to around 45% over time, showing the progress as both we and the Wayland ecosystem evolved. At Plasma 6, we switched the defaults a small bump in the graph can be seen. but 45% still seemed rather disappointing.

Filtering on just Plasma 6 reveals the true story:

There's still 20% of users switching away, or using a distro with a different default, or having carried over presets, but it's more promising. Interestingly, we can see that the GPU vendor distribution differs between X11 and Wayland.

Problems and lessons learned

Ultimately, despite the positive parts it would be hard to call our telemetry a staggering success. For the handful of examples above, there are a hundreds of cases where we had no data to back anything up. The range of data points was pitiful and it wasn't often used

The viewing tool is really, really important!

Data collection without viewing it is meaningless. As shown above, we often need to drill down and cross-reference filters to extract conclusions.

The original plan was to use the existing UI provided by kuserfeedback, which did not scale at all and quickly fell over. It was designed for high-fidelity data for a small number of users, not what we had.

In a rush, we pivoted to using Grafana because there was already a setup hosted.

It worked—ish, but it’s not designed for this, especially combined with our data structure, which was a manual NoSQL in normal SQL. Every graph needed to be written by hand, and it felt very much like fighting the system rather than working with it. Combined with the limited access permissions granted, it wasn't used by many people.

It being used is the number one indicator of its usefulness!

We need to find a tool specifically designed for visualization and querying datasets (maybe Apache Superset?).

Time-based data just makes noise

Our system sent updates every N days with basically the same data every time. This made writing queries way messier than it should have been. It never added any value; I would always be interested in what the current stats are. As described in the Wayland usage graphs above, if I'm making a Wayland decision, it doesn't matter what most people are using; it matters what people on the latest release are using. We always ended up having to add filters to focus on just the latest version.

The upgrade story needs planning in advance

The amount of data we collected was tiny—some GPU information, screen information, language, and a few other fragments. The plan was to slowly add more and more stats over time, but we hit a wall. Our UX involved the user selecting to enable metrics and it being a fire-and-forget operation.

What do we do when we want to add more data? For example, whether you use an analog or digital clock. We would need to prompt the user and reset their settings in the meantime, which is at odds with it being a setting. The whole thing became such an ordeal that made it not worthwhile.

Wrap up

The project didn't fail, when we had data and it was used it worked, but overall our implementation falls short. I would like to open a discussion at Akademy on how we move forward with our current system potentially starting from scratch treating it more like a survey that we prompt to auto populate and submit each year.

Using React in Drupal Themes Editor Fri, 08/23/2024 - 11:39

React can rightfully be called a game-changer JavaScript library for Drupal developers, as it can completely change the way interfaces are built. By integrating it into Drupal themes, we can enter a completely new world full of creativity and convenient functions, thus improving user experiences significantly. 
With the help of React, interfaces of websites built on Drupal will no longer be static and boring: they become real, interactive, and fast. Less words, let's learn more details about how you can benefit from using React in Drupal themes.

In this episode, we continued the break from JourneyInbox to look through more of the Go standard library. In this session, we talked about middleware, request context, and using databases.

The End Product

Throughout this summer, I’ve developed a C++ library called MankalaEngine, implementing three opponents for the games of Bohnenspiel and Oware.

The current library is highly extensible. After implementing all the base classes and Bohnenspiel, adding Oware to the library was fairly fast and straightforward. This focus on extensibility has been a priority since the beginning of the project. Given that the Mancala family of games comprises numerous variants, designing the API with this in mind has proven valuable.

The three provided opponents use a random selection algorithm, Minimax, and MTD-f. The Minimax and MTD-f opponents were implemented with optimizations like alpha-beta pruning and transposition tables, making them both very capable, consistently outperforming the random opponent.

For a more detailed overview of what was accomplished, I wrote a work report on KDE’s wiki.

What I’ve learned

The last few months have been a very enriching experience from a technical standpoint.

Contributing to a “real-world” project allowed me to learn about technologies I hadn’t used before. For example, I learned how to use CMake and how to set up a CI pipeline.

I also faced concerns that don’t typically arise when developing a school or personal project, such as adhering to an organization’s software standards. To this end, I learned about open-source licenses and new programming idioms.

Interacting With The Community

Since MankalaEngine is a completely new library, my interaction with the community was limited, as there isn’t an existing group of contributors for this particular project.

I mainly interacted with my mentors, who were very helpful. Although less frequently, I also had the opportunity to communicate with other KDE contributors through mailing lists, from whom I also learned a great deal.
