Russell Coker: Kogan AX1800 Wifi6 Mesh

Planet Debian - Sun, 2024-09-15 08:15

I previously blogged about the difficulties in getting a good Wifi mesh network setup [1].

I bought the Kogan AX1800 Wifi6 Mesh with 3 nodes for $140, the price has now dropped to $130. It’s only Wifi 6 (not 6E which has the extra 6GHz frequency) because all the 6E ones were more expensive than I felt like paying.

I’ve got it running and it’s working really well. One of my laptops has a damaged wire connecting to it’s Wifi device which decreased the signal to a degree that I could usually only connect to wifi when in the computer room (and then walk with it to another room once connected). Now I can connect that laptop to wifi in any part of my home. I can now get decent wifi access in my car in front of my home which covers the important corner case of walking to my car and then immediately asking Google maps for directions. Previously my phone would be deciding whether to switch away from wifi due to poor signal and that would delay getting directions, now I get directions quickly on Google Maps.

I’ve done tests with the Speedtest.net Android app and now get speeds of about 52Mbit/17Mbit in all parts of my home which is limited only by the speed of my NBN connection (one of the many reasons for hating conservatives is giving us expensive slow Internet). As my main reason for buying the devices is for Internet access they have clearly met my reason for purchase and probably meet the requirements for most people as well. Getting that speed is not trivial, my neighbours have lots of Wifi APs and bandwidth is congested. My Kogan 4K Android TV now plays 4K Netflix without pausing even though it only supports 2.4GHz wifi, so having a wifi mesh node next to the TV seems to help it.

I did some tests with the Olive Tree FTP server on a Galaxy Note 9 phone running the stock Samsung Android and got over 10MByte (80Mbit) upload and 8Mbyte (64Mbit) download speeds. This might be limited by the Android app or might be limited by the older version of Android. But it still gives higher speeds than my home Internet connection and much higher speeds than I need from an Android device.

Running iperf on Linux laptops talking to a Linux workstation that’s wired to the main mesh node I get speeds of 27.5Mbit from an old laptop on 2.4GHz wifi, 398Mbit from a new Wifi5 laptop when near the main mesh node, and 91Mbit from the same laptop when at the far end of my home. So not as fast as I’d like but still acceptable speeds.

The claims about Wifi 6 vs Wifi 5 speeds are that 6 will be about 3* faster. That would be 20% faster than the Gigabit ethernet ports on the wifi nodes. So while 2.5Gbit ethernet on Wifi 6 APs would be a good feature to have it seems that it might provide a 20% benefit at some future time when I have laptops with Wifi 6. At this time all the devices with 2.5Gbit ethernet cost more than I wanted to pay so I’m happy with this. It will probably be quite a while before laptops with Wifi 6 are in the price range I feel like paying.

For Wifi 6E it seems that anything less than 2.5Gbit ethernet will be a significant bottleneck. But I expect that by the time I buy a Wifi 6E mesh they will all have 2.5Gbit ethernet as standard.

The configuration of this device was quite easy via the built in web pages, everything worked pretty much as I expected and I hardly had to look at the manual. The mesh nodes are supposed to connect to each other when you press hardware buttons but that didn’t work for me so I used the web admin page to tell them to connect which worked perfectly. The admin of this seemed to be about as good as it gets.

Conclusion

The performance of this mesh hardware is quite decent. I can’t know for sure if it’s good or bad because performance really depends on what interference there is. But using this means that for me the Internet connection is now the main bottleneck for all parts of my home and I think it’s quite likely that most people in Australia who buy it will find the same result.

So for everyone in Australia who doesn’t have fiber to their home this seems like an ideal set of mesh hardware. It’s cheap, easy to setup, has no cloud stuff to break your configuration, gives quite adequate speed, and generally just does the job.

Oliver Davies' daily list: Looking for alpha testers

Planet Drupal - Sat, 2024-09-14 20:00

As someone who works on multiple Drupal applications, I know it can be tricky to keep on top of all the available updates.

So, I'm building a SaaS project to display all your available updates in one place.

If you're a freelancer or work for an agency or any team that works on multiple Drupal applications, this could be useful for you.

If this is you, I'm looking for alpha testers to help me test it.

If you're interested, reply and let me know.

Python Morsels: Boolean operators

Planet Python - Sat, 2024-09-14 18:45

Python's Boolean operators are used for combining Boolean expressions and negating Boolean expressions.

Table of contents

  1. Combining two if statements using and
  2. Combining expressions with Boolean operators
  3. Using or instead of and
  4. Negating expressions
  5. Embrace and, or, and not in your Boolean expressions

Combining two if statements using and

Here we have a program called word_count.py:

words_written_today = int(input("How many words did you write today? ")) if words_written_today < 50_000/30: print("Yay! But you need to write more still.") else: print("Congratulations!")

This program has an if statement that checks whether we've written enough words each day, with the assumption that we need to write 50,000 words every 30 days.

If our word count is under 1,666 words (50,000 / 30) it will say we need to write more:

$ python3 word_count.py How many words did you write today? 500 Yay! But you need to write more still.

We'd like to modify our if condition to also make sure that we only require this if today's date is in the month of November.

We could do that using Python's datetime module:

>>> from datetime import date >>> is_november = date.today().month == 11

That is_november variable will be True if it's November and False otherwise:

>>> is_november False

If we combine this with the code we had before, we could use two if statements:

from datetime import date words_written_today = int(input("How many words did you write today? ")) is_november = date.today().month == 11 if words_written_today < 50_000/30: if is_november: print("Yay! But you need to write more still.") else: print("Congratulations!") else: print("Congratulations!")

One of our if statements checks whether we're under our word limit. The other if statement checks whether it's the month of November. If both are true then we end up printing out that we still need to write more words. Otherwise we print a success message:

$ python3 word_count.py How many words did you write today? 500 Congratulations!

This works, but there is a better way to write this code.

We could instead use Python's and operator to combine these two conditions into one:

from datetime import date words_written_today = int(input("How many words did you write today? ")) is_november = date.today().month == 11 if is_november and words_written_today < 50_000/30: print("Yay! But you need to write more still.") else: print("Congratulations!")

We're using a single if statement to asking whether it's November and whether our word count is less than we expect.

Combining expressions with Boolean operators

Python's and operator is a …

Evgeni Golov: Fixing the volume control in an Alesis M1Active 330 USB Speaker System

Planet Debian - Sat, 2024-09-14 14:38

I've a set of Alesis M1Active 330 USB on my desk to listen to music. They were relatively inexpensive (~100€), have USB and sound pretty good for their size/price.

They were also sitting on my desk unused for a while, because the left speaker didn't produce any sound. Well, almost any. If you'd move the volume knob long enough you might have found a position where the left speaker would work a bit, but it'd be quieter than the right one and stop working again after some time. Pretty unacceptable when you want to listen to music.

Given the right speaker was working just fine and the left would work a bit when the volume knob is moved, I was quite certain which part was to blame: the potentiometer.

So just open the right speaker (it contains all the logic boards, power supply, etc), take out the broken potentiometer, buy a new one, replace, done. Sounds easy?

Well, to open the speaker you gotta loosen 8 (!) screws on the back. At least it's not glued, right? Once the screws are removed you can pull out the back plate, which will bring the power supply, USB controller, sound amplifier and cables, lots of cables: two pairs of thick cables, one to each driver, one thin pair for the power switch and two sets of "WTF is this, I am not going to trace pinouts today", one with a 6 pin plug, one with a 5 pin one.

Unplug all of these! Yes, they are plugged, nice. Nope, still no friggin' idea how to get to the potentiometer. If you trace the "thin pair" and "WTF1" cables, you see they go inside a small wooden box structure. So we have to pull the thing from the front?

Okay, let's remove the plastic part of the knob Right, this looks like a potentiometer. Unscrew it. No, no need for a Makita wrench, I just didn't have anything else in the right size (10mm).

Still, no movement. Let's look again from the inside! Oh ffs, there are six more screws inside, holding the front. Away with them! Just need a very long PH1 screwdriver.

Now you can slowly remove the part of the front where the potentiometer is. Be careful, the top tweeter is mounted to the front, not the main case and so is the headphone jack, without an obvious way to detach it. But you can move away the front far enough to remove the small PCB with the potentiometer and the LED.

Great, this was the easy part!

The only thing printed on the potentiometer is "A10K". 10K is easy -- 10kOhm. A?! Wikipedia says "A" means "logarithmic", but only if made in the US or Asia. In Europe that'd be "linear". "B" in US/Asia means "linear", in Europe "logarithmic". Do I need to tap the sign again? (The sign is a print of XKCD#927.) My multimeter says in this case it's something like logarithmic. On the right channel anyway, the left one is more like a chopping board. And what's this green box at the end? Oh right, this thing also turns the power on and off. So it's a power switch.

Where the fuck do I get a logarithmic 10kOhm stereo potentiometer with a power switch? And then in the exact right size too?!

Of course not at any of the big German electronics pharmacies. But AliExpress saves the day, again. It's even the same color!

Soldering without pulling out the cable out of the case was a bit challenging, but I've managed it and now have stereo sound again. Yay!

PS: Don't operate this thing open to try it out. 230V are dangerous!

Ned Batchelder: Cogged GitHub profile

Planet Python - Sat, 2024-09-14 11:27

Cog is my tool for using bits of Python to generate content inside an otherwise static file. I used it in extreme ways to generate my GitHub profile page.

If you haven’t seen it before, you can customize your GitHub profile by creating a README.md in a repo named the same as your username. So my profile is rendered from nedbat/nedbat/README.md.

My profile has a bit of static text, but much of it is badges, blog posts, links to PyPI projects, and so on. The README.md is literally a Markdown file that can be displayed by GitHub, but it’s full HTML comments containing Python code that generates the content. The generation happens once a day in a GitHub action.

There are three kinds of lines in a file run through cog: static content, code that will generate content, and generated content. My README.md is lop-sided: it has 225 lines of code, 38 of static content, and 43 of generated content.

The badges are made with shields.io image URLs. To make this easier, there are Python functions for Markdown image syntax, for building shields.io badge URLs, and so on.

I can’t walk through all of the code, but I can show a few simplified versions to convey the idea. Read the file itself if you are interested in the full details.

This makes a shields.io URL:

def shields_url(
    label=None,
    message=None,
    color=None,
    label_color=None,
    logo=None,
):
    params = {"style": "flat"}
    url = "".join([
        "/badge/",
        quote(label or ""),
        "-",
        quote(message),
        "-",
        color,
        ])
    url = "https://img.shields.io" + url
    if label_color:
        params["labelColor"] = label_color
    if logo:
        params["logo"] = logo
    return url + "?" + urlencode(params)

This makes a Markdown image:

def md_image(image_url, text, link):
    return f'[![{text}]({image_url} "{text}")]({link})'

Now we can make a Markdown badge:

def badge(text=None, link=None, **kwargs):
    return md_image(image_url=shields_url(**kwargs), text=text, link=link)

Anything print’ed will become part of the generated portions of the file. We can add a badge to the page with:

print(badge(
    logo="discord", logo_color="white", label_color="7289da",
    message="Discord", color="ffe97c",
    text="Python Discord", link="https://discord.gg/python",
))

There are other functions built on top of these to make Mastodon badges, Stack Overflow badges, a row of badges for a PyPI project, and so on.

Building the page ends up pulling data from 10 URLs, including a JSON summary of my blog for including blog posts. It’s satisfying to be able to have this update automatically instead of having to copy data around.

The result is a convenient mix of static and generated, and it was a fun exercise in light-touch automation.

Akademy went to me

Planet KDE - Sat, 2024-09-14 11:00

This year’s Akademy was a special one for me in many ways.

First of all, instead of me travelling to Akademy it took place in my hometown of Würzburg, Germany. While I did have a hand in organizing it, most of the credit for it goes to Tobias and David. I had a lot of fun introducing people to my area and the concept of drinking wine on a bridge.

Qt Contributor Summit

Right before Akademy there was the Qt Contributor Summit, also in Würzburg (what a coincidence!). It was great to meet old and new Qt faces and talk about topics that are relevant to KDE, like the upcoming migration of KDE API documentation to qdoc.

Akademy Talks

This Akademy I gave two talks: One long one where I looked back at the Qt6/KF6 transition, what went well, what didn’t, and looked towards the future of what’s next for our software platform. Then I also had a lightning talk where I talked about the role of maintainers in open-source projects, why KDE doesn’t have traditional maintainers, and why that’s a good thing.

Besides that there were also a lot of interesting talks from other people, too many to mention right now. Speaking as a member of the program committee we had some tough decisions to make about what to include.

Goals

During the conference we announced the new set of Goals that were recently elected. I’m excited that my own proposal “Streamlined Application Development Experience” got selected and I’m looking forward to working on it with you. Besides that I also want to see how I can help out with the other elected goals: “We care about your input” and “KDE needs you 🫵”.

Akademy Awards

Another way this Akademy was special for me is that I was awarded with an Akademy award for my work on KDE Frameworks and Plasma. It feels great to get recognition for all the work I’ve been doing for the last seven years.

BOFs

During the week we had lots of smaller meetings and workshops (a.k.a BOFs, world’s most terrible acronym). I was leading two of them, one about my newly-elected goal where I was presenting my proposal in more detail, and one about the ongoing work of mine to migrate our API documentation to qdoc. Thanks to our sysadmin Ben we now have a website where the current (still very much WIP) state of the new API documentation page can be seen.

Other Things

What’s great about Akademy isn’t just talks and BOFs, it’s meeting people you only see online all year, talking to them in person, getting your code reviewed while staring on a screen together, chatting over random visions, complaining about things, laughing and enjoying things together, and wrapping up the day with a nice beer in your hand.

I’m already looking forward to next year’s Akademy, wherever that will be. Maybe it will be your place, organizing it is a lot less scary than you’d think ;).

Why I Prefer Exceptions to Error Values

Tags: tech, failure, exceptions

A couple of flaws in this article I think. For instance, the benchmark part looks fishy to me. Also it’s a bit opinionated and goes too far in advocating exceptions at the expense of error values. Still, I think it shows quite well that we can’t do without exceptions at all, even in the case of error values being available. In my opinion, we’re still learning how both can be cleverly used in code base.

Why some of us like “interdiff” code review systems (not GitHub) · GitHub

Tags: tech, version-control, git

A bit too much of a rant for my taste (even though I agree with the GitHub flaws). That said it illustrates nicely a use of git range-diff which is often overlooked.

Akademy 2024

Planet KDE - Sat, 2024-09-14 02:30

This week I attended the 2024 edition of KDE Akademy in Würzburg, Germany.

Akademy CC-BY-SA 4.0 by Andy Betts

Akademy is the people. Just a bit over 100km away from Würzburg I attended my very first Akademy in 2004. Twenty years later I still meet some of the same people, as well as some I had never met in person before. Some people I had met in several countries this year alone already, some I hadn’t seen again since before the pandemic. It’s a week of hanging out with friends.

I got back physically exhausted but refreshed with many ideas and a huge motivational boost, and I can’t wait to see what will come out of all the things discussed and started there.

A big thank you to everyone who helped to make Akademy happen, and to those of you who enabled people to attend with your donations!

Topics

I’ll try to list some of the topics I ended up involved in discussing, in talks, BoFs or elsewhere, but that’s bound to only scratch the surface. Also check out Planet KDE for more reports.

CI/CD and Craft
  • If/how could we give tooling the ability to create MRs (e.g. for release automation)?
  • How can we get CI coverage for Craft and Craft Blueprint changes? At least for the latter there are some ideas.
  • Possible branching strategies for Craft Blueprints, to address the problem of all changes hitting the stable package builds immediately.
  • Ways to work around or remove assumptions in our CI/CD infrastructure about the amount of parallel branches. Usually we have a development and a release branch, but there are cases of multiple still active release branches (e.g. Plasma LTS, or overlaps during the Gear release cycle).
  • Removing the strong version locking between the Android CI image and the target Qt version.
  • Using Qt’s upcoming SBOM tooling to generate package manifests, to automate collecting and maintaining information about 3rd party dependencies we ship in application packages (for FOSS license compliance).

See also the CI/CD BoF notes and Ben’s, Hannah’s, Julius’ and my talk.

KWallet successor

How to evolve our password and credential store was also a topic, following previous discussions at GPN22 and FrOSCon.

There generally seem to be two different types of data that need their own handling and consumer-facing APIs:

  • Usernames and passwords, passkeys or 2FA secrets that you might want to sync between different devices.
  • Device-bound secrets that are not shareable, like OAuth tokens or XDG portal secrets.

Building blocks for parts of this exist, but even when putting everything together there’s still gaps.

Migration from the status quo will also be challenging, as many different things need to happen in the right order, not all of which are under our control.

Localization
  • Qt 6.6 added QQmlEngine::markCurrentFunctionAsTranslationBinding() which should allow us to make our i18n QML functions automatically reevaluate on language changes. That would be an enormous step forward for making runtime language changes work in QML applications, but it still requires a creative solution for dependency issues its use would cause in KF::I18n.
  • Debugged various cases of our Android apps mixing up translations from different languages. All of that seems to trace back to a wrong fallback handling of non-US English-language locales (we should prefer en_US as a fallback in that case, but end up using secondary languages first instead). And newer Android versions seem to have a separated region from the language settings, making it easier to hit this issue.
Static builds

Being able to build our libraries and applications statically has been on the wishlist since a long time. Work has happened into that direction, but we haven’t gotten to the point to put all this together yet.

There’s now a stronger need for this though, with the first bits of iOS support landing in Craft, and Qt on iOS can only be linked statically.

Emergency alerts

Thursday morning the Plasma Mobile BoF coincided with the yearly test of Germany’s emergency alert systems. And while we didn’t manage to capture the cell broadcast with ModemManager, the push notification based system worked.

Public emergency alert notification.

I also got a data feed for New Zealand earthquake warnings and we discussed ways to make push notifications work on Linux mobile devices even in power save mode, something that will benefit not just the emergency alerts.

Android
  • There’s a new Qt JNI array API coming, similar to something we already have in the KAndroidExtras code. More of that in Qt should help reducing the dependencies on the Android platform calendar integration, making it easier to move that to KF::CalendarCore.
  • All pieces of the window insets color API have been merged, so the Android status and navigation bars now follow the Breeze style color for KDE apps.
Android status bar matching application colors.
  • There’s agreement on retiring the KDE Frameworks 5 Android CI coverage, which would remove quite some maintenance burden. We don’t use this anywhere anymore, and external users of KF5 on Android are exceedingly unlikely as Qt5 will likely not produce APKs anymore which are in line with Google Play store guidelines.
  • We discussed ideas for a cross-platform alarm/wakeup API, to be added to KIdleTime. That is, timers that also work while the application isn’t running, or even when the device is in sleep mode.
Kongress

Kongress generally worked, and given the incoming wishes for additional features it seems it was actually used.

We did learn though that rolling out updates to event specific content for the map needs to be possible fairly quickly, this tended to need manual CDN flushes too often.

I also got a chance to try the indoor localization solution from the team we met at 37C3 in the Akademy venue. It’s unfortunately not Free Software, but it’s nevertheless interesting to see what performance/precision can be achieved without special infrastructure in the building, with just the existing radio beacons, inertial sensors and a building map. Still a bit out of reach for us, but if the past is any indication we’ll eventually get there as well I guess.

See also my talk on OSM indoor venue maps in Kongress.

Itinerary

Conference travel of course also results in work around KDE Itinerary:

  • Nobody got lost on the way to Akademy due to Itinerary issues it seems. That’s a big relief.
  • As this was my first chance of field testing the new two-level timeline view, a bunch of fixes and improvements followed from that.
  • Identified why opening the bus stop map showed the full city map instead in Würzburg (it’s the fault of the “Ringpark”…).
  • Improved stop point/quay display for large bus stations on the map.
  • Andy Betts designed new public transport icons, replacing the current incoherent mix of different styles.
  • As one attendee got Frankfurt Hahn’ed we are now looking into having Itinerary warn about airports with SEO names.
See you next time!

Looking forward to the next opportunity to meet all of you again! At least for some I don’t have to wait very long, considering the Nextcloud Community Conference 2024 today and the Matrix conference next week in Berlin.

This week in Plasma: 6.2 beta release!

Planet KDE - Fri, 2024-09-13 22:50

Technically Akademy isn’t part of Plasma, but most of KDE’s movers and shakers were here in Würzburg for Akademy 2024 this week, so the list of technical work merged was understandably light; we were all busy with conference things! I’ve already blogged about my Akademy experience separately; check it out here if you’re interested.

Despite the pressures of Akademy, quite a few things happened anyway, including Plasma’s release manager Jonathan Riddell releasing a beta version of Plasma 6.2 while at the conference. I’m very happy with Plasma 6.2. It feels great already to me. I had no hesitation pulling down git master and compiling everything while at the airport waiting for my return flight, and indeed everything was fine. But please do test the beta and report bugs!

In addition some code work also got merged; check it out below! Expect the pace of work to pick up next week and beyond as we start implementing all the cool stuff we talked about during the conference.

Notable UI Improvements

Immutable tool view tabs (as opposed to tabs for documents) now have a fancy new style! We’ll be opting into it over the course of Plasma 6.3 and other following gear and Frameworks releases, and replacing other tab-like-but-not-actually-a-tab UI elements with the real one (Carl Schwan, Plasma 6.3.0. Link):

Pressing the Meta+B shortcut to switch power profiles now cycles through them as you continue to press the key, rather than showing an overlay from which you would choose an exact profile (Jakob Petsovits, Plasma 6.2.0. Link)

System Settings’ Login Screen (SDDM) page no longer shows blurry preview images, and the dialogs that contain them have been updated to use the new modern dialog style (me: Nate Graham, Plasma 6.2.0. Link):

The alternative actions in the context menus of Plasma’s “Peek at Desktop” and “Minimize All” widgets are now expressed comprehensibly rather than being static and showing a checkbox, which made them look like persistent settings (Christoph Wolk, Plasma 6.2.0. Link)

Pressing Shift+delete to force-quit a process using SIGKILL in System Monitor now tells you that this is what will happen, rather than leaving it a secret (me: Nate Graham, Plasma 6.2.0. Link)

Throughout System System Settings’ grid views, all elided text labels now appear in a tooltip on hover, rather than only some of them (Han Young, Frameworks 6.7. Link)

Notable Bug Fixes

Fixed a high-priority Plasma crash that could happen when certain apps did certain weird things with their windows in a way that the Task Manager didn’t approve of. This also fixed a similar bug whereby certain apps might be missing from the Task Manager (Demetrius Belai, Plasma 6.2.0. Link 1 and link 2)

Fixed an issue that could cause certain added keyboard layouts to not appear in all of Plasma’s various lists of keyboard layouts you can switch between (Ismael Asensio, Plasma 6.2.0. Link)

Custom shortcuts with commands that result in their .desktop files having the same file name as an app’s own .desktop file are no longer capable of shadowing the app in software that fails to respect the NoDisplay=True key in apps’ .desktop files (David Edmundson, Plasma 6.2.0. Link)

In Plasma’s wallpaper chooser view, image previews no longer sometimes have single-pixel lines gaps around some of the edges when using certain fractional scale factors (Méven Car, Frameworks 6.6. Link)

Special KDE-specific keywords of apps and System Settings pages are now translatable into German (Alexander Lohnau, right now! Link)

Other bug information of note:

Notable in Performance & Technical

Fixed a performance bottleneck in KWin that caused it to sometimes unnecessarily copy textures across GPU devices on multi-GPU systems. This fix also happens to make Plasma Mobile work on the Librem 5 phone (Xaver Hugl, Plasma 6.2.0. Link)

How You Can Help

Plasma 6.2 just branched for the beta release, so please test it! We have focused a lot on stability for this release and want to make sure we haven’t missed anything big before the final release in about a month. Your bug reports do not go into a black hole; we triage every one! So enthusiastic testing and bug reporting is encouraged.

Otherwise, visit https://community.kde.org/Get_Involved to discover additional ways to be part of a project that really matters. Each contributor makes a huge difference in KDE; you are not a number or a cog in a machine! You don’t have to already be a programmer, either. I wasn’t when I got started. Try it, you’ll like it! We don’t bite! Or consider donating instead! That helps too.

Akademy & Qt Contributor Summit 2024

Planet KDE - Fri, 2024-09-13 20:00

I attended KDE’s Akademy and the Qt Contributor Summit that happened this year. I also completed my personal goal of giving a talk at a conference! These conferences were back-to-back and were located in Würzburg, Germany during the 5th-8th of September.

Somewhere inside Würzburg. Travel

I stopped in IAD before flying into FRA, and the journey was fortunately uneventful compared to last year. My IAD->FRA flight was delayed by an hour due to (another plane’s) mechanical issues and the ATC was backed up. When they announced that they were “sequencing” departures, I was surprised to find them actually putting all of the departing planes in a physical line on the runway.

On the IAD->FRA flight, they were having some troubles with the satellite connection and tried restarting the in-flight entertainment. While that probably did not please many of the people enjoying their movies and shows, it did reveal the in-flight entertainment system for United flights were running Android. Boo, that’s no surprise.

The trains I were on weren’t too late and I quickly arrived in Würzburg after a transfer to Frankfurt Central Station. To save some money, I purchased a Deutschland-Ticket which covered most local transportation, including the buses in Würzburg proper. The ticket was only 50€, which if I had paid for the trains separately would mean at least 65€! I didn’t bother calculating how much bus fares would’ve cost. So the D-Ticket was definitely worth it during my stay.

At one of the stations outside the airport. Yes, I did take the S-Bahn in the wrong direction…

On my returning overseas flight, the plane was half-empty. So I had a row with window seat all to myself, it was pretty sweet! Is this how flying first-class feels?

A full row to myself! Hotel

I stayed in Hotel Amberger, close to the central station. It’s a cute little hotel, housed in a building that was clearly repurposed (my guess is some kind of hospital.) The hotel rooms are dead simple, but I didn’t really care. The first few days were really hot and the lack of a central air conditioning was really noticeable. Once the weather cooled off, the room was much more hospitable.

My hotel room.

The hotel room had a TV, but mine did not work. No German TV for me this time! There was multiple bus stops near the hotel, so it was very easy to get to the Akademy venue. The QtCS venue was within walkable distance, so I walked there each day.

Qt Contributor Summit

This being my first Qt event, I didn’t really know what to expect. The venue is hosted in this expensive-looking conference center ( Congress Centrum Würzburg) near the river. There was catered food, which included lunch and coffee breaks. Dinner was served on the first day. I noticed the wait staff and looked young so I wonder if they were local culinary students.

The talks were a mixed bag of topics, but I still found value going there. Most of the non-Qt people there were either KDE or KDE adjacent, of course. One of the cooler things for me was meeting a bunch of Qt people in person. Of whom I only knew by name, mentioned in e-mails and Gerrit, so on. Lots of people recognized me by my work on qmlformat, so that was neat.

The talk that interested me the most was Vladimir Minenko discussing “QML Next”, plans to use languages other than C++ with QML. Some languages discussed were Swift, and C#. Curiously Rust was absent, which he did duly note. They did mentioned they were hiring a developer to work on Rust support later this year. The talk itself the concept was a bit vague, but that’s because they’re still in the exploratory stage.

If you’re interested in the other talks in this conference, there are notes and slides available from the Qt Wiki.

Akademy was hosted in Julius-Maximilians-Universität Würzburg, which was much farther than the venue for QtCS. That necessitated travel by bus, but that was also covered by the D-Ticket. The talks were hosted in two identical-looking lecture halls. On a bus heading towards Akademy one day, I noticed one of the screens didn’t work. Of course, I had to take a picture…

The bus screen in some sort of debug mode.

My talk was about integrating C++, Qt, Rust (and KDE Frameworks.) For proper disclosure, this talk is on behalf of my company for spreading the word of our cxx-qt library which eases integration of all of these technologies. I think was a bit too rough structurally but lots of people seem to enjoy it. One of my goals was to raise awareness of the usage of Rust you can find in KDE today, and that seemed to be successful! I want to express my gratitude to my fellow colleague Leon Matthes for helping review my slides. Also thanks to Darshan Phaldesai for his KDE work featured in the presentation.

A picture of me hastily giving my presentation.

The results of my talk I think were really cool! Within the KDE community, there seems to be some interest in picking up Rust. Lots of KDE developers were in varying stages of Rust interest. No one told me how stupid it was to glue the two together, so the general vibe I think is “it’s pretty neat, let’s see how well this works.” Unfortunately due to technical issues my talk was not recorded properly. A colleague recorded my talk on his phone, and will hand that over to the Akademy organizers soon. So please be patient, but the slides are available online while you wait.

Oh yeah, and the KDE goal I’m championing “We care about your Input” was selected! I’m pretty excited to keep hacking away on graphics tablets in KDE Plasma. Thanks to NLnet for sponsoring us to work on that, along with Wayland accessibility improvements.

One of my favorite talks was Xaver Hugl’s “What even is color?”. The work he’s doing in KWin is excellent, and I think he did a really great breakdown to understand what color management is.

Day Trip

In the day trip we went to Rothenburg. It was rainy, cold and miserable most of the day but we still had fun. One of my favorite parts was climbing up the tower to get an excellent view of the town.

A picture of the tower. A view from the top of the tower.

That’s all I have to say about Akademy + QtCS, I had lots of fun this year! I’m happy that I was able to attend the talks this year, and meet a lot of people I missed last year. I hope everyone else were able to return home, and I’m excited to see what event I’ll attend next. See you!

My Akademy 2024 trip

Planet KDE - Fri, 2024-09-13 20:00

Akademy is this yearly thing where bunch of KDE people go to talk about and work on KDE software. I had never been in one before, but this year I managed to make it there! This year Akademy was held at the city of Würzburg. This was also my first time in Germany, which is the furthest I've ever been from home.

I also had my wife Jenny with me, since if I had gone alone I would have gotten lost in some random mountain somewhere, or started a new life at the dark corners of Frankfurt airport, completely confused.

Friday, the day of flying (or so I thought)

On Friday the 6th, we left from Oulu to Helsinki first. Hop on plane at 14.30 and- Oh, a small delay.

Eh, it's fine, we hopped on the plane at 16.00 and-...

The flight was canceled.

So, we wait til like 19.30 or something to get to Helsinki. But of course, our flight from Helsinki to Germany had already left! No worries though, the next flight to Germany would leave soon.

Wait, what do you mean it leaves at 7.00?

Aaaaaaaaaahhhhggggggggggg....

Well, we got paid airport hotel room with paid dinner and breakfast. So we slept at Helsinki the first night. We were supposed to be at Würzburg at 23.55 or something, but of course not. Oh well, with some effort I might be able to make to the event, although I would miss the first few talks.

I had the most saddest (but still good) slab of lasagne at very sad and empty airport hotel restaurant. Very frustrated by everything. Sure it'll get better, right?

Saturday, the day of sleep deprivation

This time the airplane actually started to fly, instead of getting canceled for scandalous airplane activities, and we were on route to Frankfurt pretty soon. I spent some time in the airplane just working on my never-ending game project.

At Frankfurt, we got our luggage and went to the funny ICE train, which was a bit late. Apparently being late is some German train thing, I don't really understand it, but we have similar thing at Finland so it wasn't that shocking.

At the train, we were exhausted with our 4h of sleep due to stress not allowing us to sleep, so we just find some seats and sit down. Five minutes later some chap tells us to go away, so we stay up standing for the next 1h 30min next to the exit doors in some midcabin thing.

I wanted to watch some of the Akademy streams at this point, but I was mostly focusing on staying up.

Eventually, we finally reach the Burg of Würz. First impressions were that it looks really nice and.. What the hell is that? A.. mountain? Wow, they can be THAT tall??? (Authors note: Finland is very, VERY flat).

Also it was hellishly hot. The most I saw was 32 celsius. It was painful, I was sweating all the time and it was not fun.

We walk to our hotel room at Mercure hotel, which was really nice by the way. At this time, Akademy was having an incredible luncheon together, so me and Jenny decided to find something to eat. We found this place that was all about avocados, and I had something called powerbowl, which was brilliant.

After that, we began to study the incredibly complex thing that is the German bus system and started our trip towards the Akademy venue.

Aktually at Akademy

Me and my blurry sleep deprived brain walk to the venue and first off I meet familiar people. A lot of familiar people. Many hugs and "Oh you finally made it!"-s were shared. Jenny was with me there as well and it was fun to introduce her to my friends.

I honestly don't remember much about the day. It was quite a blur. But it was cool and I talked a lot.

I stole a lot of stickers and listened some talks, which I can barely remember... But I do remember which ones:

  • Arjen's talk about Union KDE styling theme thing, that is super cool.
  • Harald talked about of our own new possible shiny OS called KDE OS. Or 🍌 OS. I found this really exciting.
  • A lot of lighting talks, where Nicole's talk about teaching lil kiddos how to install Linux with KDE software on old PC's to bring them back alive.
    • I think this talk was my favorite. It was very wholesome, motivating and I'd like to have similar kind of teaching event at home. No promises, but.. Maybe!

During this day I also began to give out salmiakki to people, since I had been well prepared. It was kinda fun to see peoples reactions, especially if they had never heard of it before.

Then it was back to sleep at the hotel.

Sunday, I managed to do things

On sunday I was at Akademy pretty much the whole day. Again, I listened bunch of talks, met more people and we had many good chats about LTS distros, KDE PIM, Kwin, Flatpak... And many other things I can't remember.

I listened Carl's KDE Apps Initiative talk which was very motivating for me, since I've wanted to make a KDE app for a while. A gaming related lil thing.

After the fun group photo and delicious lunch, I chatted more and wandered about the venue.

There was a talk about daily driving Plasma Mobile and I found it very cool, and we had a chat about the Plasma Mobile afterwards. Apparently my Fairphone 5 could run PostmarketOS with Plasma Mobile pretty well already, but I am not yet ready to commit to such a change with my mobile device.

Last I listened Xaver's talk about what color is in computers. I learned that sRGB is a lie and gasped audibly, then heard a lot of words related to color systems I didn't really always understand.. But I found the talk still quite interesting and informative.

The evening was then again a bit of a blur, with sponsors lightning talks and Akademy Awards (congrats to winners btw).

Very interesting day, but I've always been bad when it comes to learning from listening. I learn by doing.

Of course the day wasn't complete without me going to wait bus with my t-shirt and shorts (since it was hot again), and it started pouring like heck. I was soaked when I got to the bus, then at the last stop I had to walk 1km to the hotel in the rain. Ah well, it was warm so I didn't mind too much.

Monday, I skipped the class

On monday I was so exhausted by Everything:tm: I decided to just chill with my wife and we went around Würzburg, buying food and chocolate.

I spent that day just recharging my social batteries. And I ate some Flammenkuchen, which was delicious!

At some point when Jenny is done editing and uploading her video, I will make separate post for it. Then you can see what Würzburg is like, and hear what she did during the trip.

Tuesday, I flocked together with the birds

Like on monday, on tuesday as well Akademy had these events called "BoFs" which is abbreviation of Birds of a Feather. Because "Birds of a Feather Flock Together". I don't know why it's called that, but anyhow, I participated a few of them:

  • New design system bof
    • Very interesting discussions and ideas even I know nothing about design
    • I was mostly hoping to help people there with my programmer side of knowhow, as someone who has touched the Breeze styles codebases
  • Tiling in kwin bof
    • We mulled over what we could do to make tiling in kwin even better
    • I have this mini task for myself where I try to make tiles split automatically when a window is dragged on top of the other
  • Fedora KDE bof
    • I was just mostly curious whats up with Fedora KDE at the moment
    • I also wanted to give my praise for Fedora KDE, it's been my daily driver for many months now and it's been really good
    • Couple of my friends use it too due to my recommendation and they're having good time gaming on it! :)

To wrap up the evening, I had a fancy dinner with my friends. What was quite a culture shock to me was that after 22.00 the streets were practically completely empty. It was eerily quiet. At home we would have had few drunks about making noise, but at Germany there was just.. Silence.

Wednesday, to home again

Due to having two lizards and them needing a petsitter, and said petsitter not being able to be there the whole week, we left a bit early so we missed the daytrip and the last bof day.

Bit early being our flight from Frankfurt was leaving around 7.00. So we woke up at 5.00.

And when I wake up I saw a message in my phone saying: "Hi your flight is canceled"

Ah. Fun. If all had gone to plan, we would've been at home around 17.00. But instead, we were home at ~2.00.

We had to live at Frankfurt airport for ~7 hours, saw a lot of police with weapons (it was really scary to me, I've never seen weaponry like.. that openly), there was some suspicious luggage that got a whole McDonalds covered in "dont go here" tape and more police.

Urghgfhklfg. Scary.

Eventually we luckily made it to Helsinki and then back to Oulu and I didn't need to type out this blogpost from some corner of the airport.

Conclusions

Akademy was really fun event. I can hardly describe how fun it was. It's been quite a blur due to traveling issues and thus me being completely stressed and exhausted, but I still had many fun chats with everyone.

It was really nice to finally see who the people behind the internet names are and have talks with them, be it just random topics or KDE topics. I met people who I had never met before and shared many chats, laughs and information with them.

I learned quite a lot about what's going on in our KDE ecosystem and even outside of it, how we all interact. But I think the biggest thing I learned was that events like Akademy are crucial for the motivation and wellbeing of the KDE community. It helps us stay together, keep our bonds strong, be it KDE folk itself or people working with us, and keep us being awesome at what we do: Making computers do cool things, for free, for productivity and for fun.

Sorry about no photos, I have basically nothing: I am very bad at taking photos because I simply don't remember.

I love KDE and if you love KDE too, and if it's at all possible, visiting Akademy is well worth it!

See you at the next one, and apologies for the all-over-the-place-rambly-travel-post. Hope you find it a good read anyway.

Thanks for reading!

Qt Contributor Summit and Akademy

Planet KDE - Fri, 2024-09-13 20:00

This year I went to Würzburg, which is a nice small German city famous for its wine. But I didn’t only go there for the wine, but also to attend Qt Contributor Summit and Akademy.

Qt Contributor Summit

The travel to Würzburg didn’t go as planned as Deutsch Bahn had some technical issues with their train and couldn’t reboot our train. We still managed to get in Würzburg on time and even had the change to get a small touristic tour from some locals.

Würzburg Residence and the Wine briget

The event itself was great and was the first time I attended fully a Qt Contributor Summit. Last year, I only attended a few session since the event was 20 min away from home.

There was many breakout rooms focused on some spcial topics, for me the most interesting sessions were about Qt for Python, how to hate QML, qt-project.org, Vector Graphics in Qt.

It was great to see how the KDE community still plays a big role in Qt and the Qt developers really appreciated what KDE finally moved to Qt6. They reported that the flow of contributors and bug reports increased.

Qt Chief Maintainer Volker Hilsheimer even stressed out how important it was for some of their customers to see KDE ported to Qt6, as it shows what Qt6 is stable and mature enough. Qt6 is indeed a hugo improvement over Qt5 and I am very happy how good the transition was.

Qt Contributor Summit

I think it was a great idea to have Qt Contributor Summit just before Akademy. This allowed to have many KDE Contributor to the Qt Contributor Summit and many Qt developers to Akademy. It would be great next year to do the same next if possible and encourage more people from the Open Source Qt ecosystem to join too.

Akademy

Once the Qt Contributor Summit ended, we started a few hours later with the Akademy welcome event for some KDE beers. But before that, I had some bubble tea and spent some time with some friends exploring the city.

The weekend was full with a lot of great presentations. I presented a small report about the Accessibility Goal and the Fundraising working group. I also gave a bigger talk about the KDE Application Ecosystem, which I am really passionate about. The whole slides ware made with Calligra.

I was also very happy to see the new elected goals.

Sunday was also my birthday, thanks to everyone for congratulating me. I also received a super fancy special birthday sticker and some amazing cake.

Cake and stickers

Day Trip

We had our yearly day trip too, this time at Rothenburg ob der Tauber. A charming small town in south Germany.

Day trip Rothenburg ob der Tauber

BoFs

The next few days were filled with BoFs and many informal discussions. During the Promo BoF, we decided to create a “This Week in KDE Apps” blog posts. Paul volunteered Tobias, Joshua, and me as the initial team for this.

I also hosted a BoF about a future replacement of KWallet. There were some discussions about the scope of this effort. Should we just focus on storing OAuth2 tokens as a background service what the normal users should never interact with or do a full-blow password manager like macOS Keychain. I presented my work toward the latter around based on KeePassXC and the KeePass format (see my old blogpost) as it would allow to use a standardized file format that also work on other platforms. The KeePassXC developers are working on providing a reusable library, so we don’t need to fork their code. There will likely be more discussion about this in a separate gitlab issue. The lack of a good story around passwords is not unique to KDE but to the whole Linux ecosystem. If you have some opinions about this, feel free to reach out.

I discussed with Ben, Lydia and Aniqua the infrastructure for newsletters for our supporting members. Ben managed to get an instance of Listmonk in a matter of minutes and this seems to be the right way for us to manage a newsletters or at least way better than using a mailing list for this.

Kieryn hosted the best BoF: the Sticker BoF where we shared stickers and had a competition to see who had the best decorated laptop. I won!!! and received another special sticker. Thanks Kieryn for organizing this BoF and generally making Akademy this year such an awesome event!

Stickers

I also ended up finishing a lot of work. I finally ported the last Drupal 7 website to Hugo: dot.kde.org which was a quite massive website with more than 20 years of history. I migrated the Hugo version used by KDE from 0.110.0 (which was more than a year old) to 0.134.0 and I am happy to report that the Hugo folks care a lot about stability and there was only some very small breaking changes. If you are working on some KDE websites, don’t forget to download the latest version of Hugo and to run the following command to update the KDE Hugo theme.

hugo mod get invent.kde.org/websites/hugo-kde@master

With Volker, we finally merged the status bar integration for Android apps so that KDE apps running on Android and now use breeze colors in their status bar, which looks much more integrated and like on Plasma Mobile.

Itinerary on Android with the new statubar

I also got some improvements ideas during Akademy, and I already started implementing some of them: https://invent.kde.org/pim/itinerary/-/merge_requests/324

Finally I started rewritting the Calligra launcher to Kirigami based on the old Gemini UI. Still a bit far away from a being in a mergable state but it already looks quite good.

Calligra text document templates selection

Calligra new document

Conclusion

This was a great Akademy again. Thanks a lot for all the organizers for all their work. I hope to see some KDE contributors again soon at the Nextcloud Conference and Matrix Summit both in Berlin this month. And to the Linux Days in Dornbirn.

KDE Plasma Wayland keyboard layouts

Planet KDE - Fri, 2024-09-13 18:00

Calamares is a Linux system installer used by dozens of distro’s to get the bits from an ISO image onto a target computer. Development is nowadays purely on a volunteer basis, which makes it hard to keep up with all the changes in the Linux world. But steps are made, and code submissions are very welcome, and here’s a note on something relatively new and useful: Wayland keyboard layouts.

Some History

In an X11-based system, the X server is the one thing that knows how to interpret keystrokes (pressing the button on a bit of hardware, e.g. the button to the right of the one labeled CapsLock is labeled A and makes the letter “a” when pressed). The X server can be told how to interpret the buttons: one command is setxkbmap which can manipulate the keymap:

$ setxkbmap -query rules: evdev model: pc105 layout: us options: ctrl:swapcaps

Using setxkbmap you can change the layout from the command-line: setxkbmap -layout us changes it to US-English, setxkbmap -layout ua changes it to Ukranian, and there’s tons of other layouts.

In Ukranian, pressing the keys labeled WASD yields “ЦФІВ”.

Changing the keyboard layout is just a matter of being connected to the X server – any X11 terminal program can do it, or an application can do it programmatically by sending the right X11 protocol messages.

Wayland

There isn’t a standardized mechanism in Wayland to request a different keyboard layout. It’s up to the compositor how and what it wants to do.

Some compositors are willing to listen to systemd’s locale1 service. KWin does this, but only when started with suitable command-line flags. Many systems that start KWin as part of their live installation do not pass that flag. Some compositors just don’t implement this at all.

KWin (Wayland)

The way to tell KWin to change the keyboard layout is to rewrite the configuration file for keyboard layouts in KDE Plasma, then send a DBus signal to KWin.

You can see that happening here, at least as of the code in April 2024. I suppose the idea is that the only way to change the keyboard layout is to go through the KCM, click on the list of layouts, manipulate it, etc. and then click apply.

For those cases when I briefly want to type Ukranian, or Arabic, that’s really annoying. For Calamares, which tries to set the keyboard layout when you select one, that’s really annoying.

Calamares and KWin

In the upcoming Calamares 3.3.10 release, the installer can be configured to edit KDE Plasma’s keyboard configuration file. I imitated the code from the KCM, but without relying on KConfig because that would be yet-another dependency for Calamares. This is a total bodge job. But it works!

For distro’s that use Calamares, and use KDE Plasma, and come up with a live system that uses Wayland (e.g. Asahi Linux) this means that keyboard layout updates can now be applied consistently, and you can e.g. type your password in the keyboard layout you’re actually going to use.

It ain’t pretty. Frankly, I think there should be a standardized way to say “use these keyboard layouts”, but I also understand that that opens the whole can of worms of “who should be allowed to change the keyboard layout?”.

Disable the Plasma Morphing Popups effect (at least on X11)

Planet KDE - Fri, 2024-09-13 16:48

If you're using Plasma/KWin 6 i suggest you disable the Morphing Popups effect, it has been removed for Plasma 6.2 https://invent.kde.org/plasma/kwin/-/commit/d6360cc4ce4e0d85862a4bb077b8b3dc55cd74a7 and on X11 at least it causes severe redraw issues with tooltips in Okular (and i would guess elsewhere).

After Akademy 2024

Planet KDE - Fri, 2024-09-13 14:02

This year’s Akademy (KDE’s annual conference) in Wurzburg, Germany was a success!

Yours truly had a chance to speak during the Akademy days and present our new design system to the community.

As previously reported in my youtube channel and in my posts, we provided a set of design system foundations to the community for their use in the future. This means, designers and developers will more closely work in the design process.

A few new faces also appeared at the venue. This was amazing! New contributors excited about our technologies is always welcomed.

In addition to the main session, our Visual Design Team put together an additional Birds of a Feather (BoF) session the following day. I have to say that I have never seen this many people interested in our presentation before and I am greatly appreciative of their desire to help.

We split our BoF in 3 sessions. The main session was an exploration of our export plugin for Figma and PenPot (Authored by Manuel de la Fuente), and also a review of the actions the VDG (Visual Design Group) needs to take to publish the work in the design system.

Our second hour was dedicated to reviewing our visual changes acceptance guidelines (led by Nate Graham). This session was intended to speed up the rate of response for visual design changes in Plasma and other areas. This should help us go faster and be more effective in our decision-making process.

The work is tracked here:
https://invent.kde.org/teams/vdg/issues/-/wikis/home

Our third hour was dedicated to Arjen Hiemstra’s new unified theme builder “Union”. Arjen showed us the source code and current capabilities of Union. It’s still early days but the progress is huge. There are a few new features that Arjen wants to add to the engine and we should see more of them in the near future.

Throughout the week, we dedicated time to testing and bettering the icons we produced. Our next objective is to address the latest round of feedback and then begin the process of editing our 16px icons to match our shapes in the 24px collection. Additional to that, we still need to find as many bugs as possible with the new icons.

During one of our sessions we noticed that some icons did not work properly in dark mode. This was a good test to do as some of the shapes didn’t recolor properly. Good thing that we were surrounded by Plasma devs and it was easy to spot the problem! This, however, does not mean the icons are free of issues. They still need a lot of work.

For now, I would like to invite all those who would like to provide feedback and/or test the icons. Please note that this is as alpha as it gets. There is a lot more to be done. Until all icons are finished, you can test the 24px collection.

Plasma Icons 24px collection:

https://www.figma.com/design/F38rWWFmFRcyolDk07xxKw/Icons?node-id=0-1&node-type=canvas&t=FiBCevySX0c6XmBE-0

Soon enough, I will also edit a few of the images I took from the city and during Akademy. Needless to say, this one was by me!

Aren’t we cool?

See you all soon!

Akademy and Kdenlive Sprint report

Planet KDE - Fri, 2024-09-13 13:53

Part of the Kdenlive team attended this year’s Akademy – KDE’s annual conference in Würzburg, Germany. Since we don’t have so many occasions to meet in real life, we also used the event to make a Kdenlive team sprint.

So here is a report of what happened during these busy 4 days !

Documentation

We first discussed how to better integrate our great documentation inside the Kdenlive app. We already have a kind of hidden link in the effect list that redirects the user to the documentation website, but decided to make the feature more visible and you will now (to be released in 24.12.0) find a small info button redirecting to our doc. In the process, we fixed and improved many links so that you now directly access the correct page.

https://kdenlive.org/wp-content/uploads/2024/09/online-documentation.webm

Roadmap

We discussed our roadmap, moved the tasks that were completed in a dedicated column. We also reviewed the remaining tasks and reorganized them to better align with our priorities.

Fundraising

We reviewed the tasks planned in our fundraising, what has been done and what is left, more on this will be announced in an upcoming post soon.

Kdenlive Café

We decided to go for one online user Café every 2 months.This is a great way to stay in touch with the community, and we plan to have themes for these events, for example creating content with Kdenlive, Development news and coding introduction, How to contribute (documentation, testing, etc). Next one will be in November, focused on the next December release. Stay tuned for the date.

Render Test Suite

Last year, we worked on a rendering test suite that is aimed at automating rendering and comparing the result with a reference video file. The goal being to detect and prevent regressions in our pipeline. Unfortunately, since it still requires a local install and manual triggering, we are not really making use of it. During the sprint, we worked on making it run on our current CI infrastructure for full automation. Some good progress was made, there are still a few things to debug.

Website

We discussed possible changes regarding our website, more to be announced later this year.

LV2 Audio Effects

With the recent introduction of an LV2 module in our video backend MLT, we made tests with some LV2 audio effects. Some effects that don’t require a specific UI work but session state (saving and restoring the effect data, for example with the noise repellent plugin) is not yet implemented in the MLT module, so its usability is currently very limited.

AI Effects

We discussed and tested a few models providing AI effects. Some work has to be done to make the way we integrate python scripts more modular, we will soon start working on this.

Bugs

We didn’t have enough time unfortunately to do much work on the bugtracker but still managed to tackle a few issues. Among them, we found the reason for missing notifications on Windows, found 2 regressions in our video backend causing affecting playback smoothness, and various smaller bugs.

Akademy

Between our Sprint sessions, we also attended several of the Akademy talks, and met great people there. Julius made a talk about his work on the CI regarding packaging and notarization. Some of us also attended a translation workshop so that we can better guide interested contributors.

 

Busy week-end, and you will hear again from us soon!

The post Akademy and Kdenlive Sprint report appeared first on Kdenlive.

Akademy 2024 in Würzburg - it was a blast

Planet KDE - Fri, 2024-09-13 11:31
Akademy 2024 in Würzburg – it was a blast

My second Akademy and has ended just yesterday. It was an amazing and productive time again! Apart from familiar faces I know from last year's Akademy or the Plasma sprint last year in Augsburg, I met plenty of new faces. Some of which I of course had contact in KDE before, but only in the digital world.

One of the best parts was again the day trip with the KDE Community. While it was a bit rainy, we for sure made the best of it and saw the beautiful city of “Rothenburg ob der Tauber”. The view from the town hall tower was very beautiful:

The talks were also quite interesting and highlighted how many facades the KDE Community has. Apart from the lightning talks being great again, the “QML in Qt6” talk was quite valuable, because I did not manage to follow up closely on the latest improvements.
The talks and BOFs related to the KDE goals were also quite beneficial in getting a good impression in what direction we want to go.

Since we had so many interesting talks, it was not possible to join all of them. What I will follow up on later are the talks “Pythonizing Qt” and “C++, Rust and Qt: Easier than you think”.

Albert Astals Cid and I gave a lightning talk together about JSON linting (my part) and QML linting (his part). We were only able to touch the surface in the given time, but had some productive discussions and follow-up questions afterward. I will create a post about the JSON validation/JSON schema topic in the future, since I am still working on some aspects of this.

It has been great again to also do some hacking together and discuss ideas in-person. I will miss being able to say “Let's discuss this at Akademy?” on merge requests ;).
I did quite a bit of hacking on KRunner, linting/formatting related tooling and also Clazy.
This can also be seen on my GitLab history that has turned a bit more blue and thus active:

What was a great improvement over the last Akademy were the chicken noises to make sure people stay within the time of their talk! To better improve on that, we should maybe get some real chicken next year 🥚🐣🐔. The talks on how to apply for funding in KDE might contain useful info when working towards this ;) PS: My life-long profile picture on GitHub/GitLab is of the super cute chicken I had 🥰.
