This is a big one, folks. Plasma 6.2’s soft feature freeze is now in effect, which means the last few features have just been merged! Now we’ll have six weeks of heavy bug-fixing before the final release in October. If you’re an industrious sort, the time to live on git master and report bugs is now! Current git master is completely suitable for daily driving.

And we’ve already been focusing on QA for a while, so new bug reports take priority — both triaging them and fixing them. Over the past few months, we’ve succeeded in dropping plasmashell’s total number of bug reports to 1022, the lowest in several years. And the number of unconfirmed bug reports is currently down to 301, the lowest since late 2015! Triaging and fixing bugs is a priority, and we’re promptly triaging all new Plasma new bug reports daily. Our goal is to push the number of unconfirmed bug reports under 200 by the end of September.

So please do submit bug reports for any issues you encounter; it’s not a black hole. If you’ve complained about bugs on social media recently and haven’t reported them on https://bugs.kde.org, fix that today! Do it! Do it now!

…But first check out the final Plasma 6.2 features; I think they’re pretty awesome. It’s gonna be a big release, full of useful stuff!

Notable New Features

It’s now possible to block apps from inhibiting sleep and screen lock, if you don’t like the fact that they do so (Natalie Clarius, Plasma 6.2.0. Link):

Newly installed Plasma widgets are now shown at the top of the grid view and badged with “New!” for one hour, so it’s easy for you to find them right after installing them (Niccolò Venerandi, Plasma 6.2.0. Link):

While choosing a custom image for a user avatar on System Settings’ Users page, you can now crop the image if needed (someone going by the Pseudonym “Kuneho Cottonears”, Plasma 6.2.0. Link):

Added support for 7-day weather forecasts and “chance of precipitation” data for BBC UK Met weather stations shown in Plasma’ Weather widget (Ismael Asensio, Plasma 6.2.0. Link):

Discover now gently guides you in the direction of writing better reviews for non-proprietary apps (me: Nate Graham, Plasma 6.2.0. Link):

https://i.imgur.com/SGTpj9a.mp4

Added a yearly notification to ask for donations; see this week’s earlier post for more details (TL;DR: optional, once per year, you can permanently disable it) (me: Nate Graham Plasma 6.2.0. Link)

The plasma-apply-wallpaperimage tool now has a --fill-mode option, mirroring the existing GUI option for this, but now in a scriptable form (Heitor Augusto Lopes Nunes, Plasma 6.2.0. Link)

Notable UI Improvements

Due to popular demand, KWin’s Overview effect once again shows a linearized representation of two-dimensional virtual desktop layouts (e.g. 2×2, 3×3, etc) on the primary view, rather than hiding them entirely (Blazer Silving, Plasma 6.2.0. Link)

Plasma’s System Tray now uses a better grid layout for the expanded view that leaves more space for text, which is especially important for languages like German and Russian. The new layout saves space, too (me: Nate Graham, Plasma 6.2.0. Link):

The settings for KWin’s colorblindness correction effect now live in the logical place where you’d expect to find them: on System Settings’ Accessibility page! (Thomas Duckworth, Plasma 6.2.0. Link):

Overhauled the UI of System Settings’ Accessibility page in a lot of little ways to make it actually be more… accessible! (Thiago Sueto, Plasma 6.2.0. Link)

Plasma’s “Minimize All” widget now only minimizes and unminimizes windows on the current virtual desktop and activity, rather than all windows everywhere (Christoph Wolk, Plasma 6.2.0. Link)

If you enter global edit mode, and then from there enter a panel’s own edit mode, closing the panel’s configuration window now simply returns you to the global edit mode, rather than exiting from that too (Niccolò Venerandi, Plasma 6.2.0. Link)

The error message shown when manually installing a Plasma widget fails is now more descriptive, and tells you the actual error so you can troubleshoot it (Nicolas Fella, Plasma 6.2.0. Link)

Made a pass over many areas of Plasma and System Settings to align text and labels with our Human Interface Guidelines’ best practices (Christoph Wolk, Plasma 6.2.0. Too many merge requests to list TBH, so check them all out here!)

Dialog windows throughout KDE software have new icons again — this time they look nicer and more Breeze-styled (Kai Uwe Broulik, Frameworks 6.6. Link):

Notable Bug Fixes

Fixed a nasty issue that could cause corruption in files on SFTP servers that were edited by opening them from Dolphin in an app and then saving changes (Ser Freeman, kio-extras 24.12.0. Link)

Changing the system’s Global Theme now also changes the colors of any recolorable GTK apps, just like you’d expect (Michael Weghorn, Plasma 6.1.5. Link)

Performing a multi-finger touch swipe/gesture on your touchscreen no longer messes up Plasma and gets it caught in a weird limbo state (Marco Martin, Plasma 6.1.5. Link)

Fixed a recent regression in Plasma’s desktop file/folder view that could cause items to snap back to their previous locations after being dragged somewhere else (David Edmundson, Plasma 6.2.0. Link)

Job progress notifications shown by Plasma no longer let any buttons’ text get cut off in languages where words and phrases are long; now, the popups expand horizontally a bit to make room (Arjen Hiemstra, Plasma 6.2.0. Link)

Fixed two issues in Plasma’s Emoji Selector app seemingly caused during the Plasma 6 port that caused it to lose its prior selection highlight effect, and always copy the first item in the search results view rather than the selected one (Akseli Lahtinen, Plasma 6.2.0. Link 1 and link 2)

Substantially reduced the glitchiness of the tooltips for items in the expanded view of Plasma’s System Tray (me: Nate Graham, Plasma 6.2.0. Link)

Fixed a glitch that could cause the Maliit virtual keyboard to be mis-positioned when using any vertical panels (David Edmundson, Plasma 6.2.0. Link)

When Plasma’s Folder View widget is placed on a panel, its popup can now be resized to smaller than its default size (me: Nate Graham, Plasma 6.2.0. Link)

It’s no longer possible to break System Settings quite terribly by opening a “Get New [thing]” window and then closing System Settings’ own main window (Harald Sitter, Frameworks 6.6. Link)

Other bug information of note:

• 2 Very high priority Plasma bugs (down from 3 as last week). Current list of bugs
• 33 15-minute Plasma bugs (down from 36 last week). Current list of bugs
• 149 KDE bugs of all kinds fixed over the last week. Full list of bugs

Notable in Performance & Technical

Substantially improved performance in Discover in multiple ways: launch time, time to load the UI, time to load icons, and smoothness of scrolling through long lists (Harald Sitter, Plasma 6.2.0. Link 1, link 2, link 3, link 4, and link 5)

Discover now behaves more sensibly and only shows one authentication prompt when asked to update multiple Flatpak apps in an environment with hardened security for Flatpaks, as in openSUSE distros (Harald Sitter, Plasma 6.2.0. Link)

Installing a font now places it, by default, in a standardized location (e.g. ~/.local/share/fonts/rather than the legacy location (~/.fonts/), which means that sandboxed apps will be able to find and use them as expected (David Edmundson, Plasma 6.2.0. Link)

…And Everything Else

This blog only covers the tip of the iceberg! If you’re hungry for more, check out https://planet.kde.org, where you can find more news from other KDE contributors.

How You Can Help

So yeah, like I said, please test Plasma from current git master and open bug reports about issues you find. Another path is to help triage bug reports that the first crowd will be opening. Ask for more information, make them actionable, move them where needed! And of course, help fix triaged and confirmed bug reports.

Otherwise, visit https://community.kde.org/Get_Involved to discover other 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.

Python is known for its simplicity and readability, but one feature it has historically lacked is a native switch case statement, commonly found in other programming languages like C, C++, and Java. Instead, Python developers often relied on a series of if-elif-else statements or dictionaries to emulate switch-case behavior.

However, with the release of Python 3.10, a new feature known as “Structural Pattern Matching” was introduced, which effectively brings a form of switch-case functionality to Python.

In this tutorial, we’ll explore how to use the switch case statement, Python’s new approach to handling multiple conditions in a more readable and efficient way.

Introduction to the match Statement

The match statement in Python 3.10 allows for pattern matching, which is more powerful and flexible than the traditional switch-case statements found in other languages. Pattern matching checks a given value against a series of patterns and executes the corresponding block of code when a match is found.

Here’s a basic structure of how a match statement works:

Pythondef example(value): match value: case pattern1: # Code block for pattern1 case pattern2: # Code block for pattern2 case _: # Default case (similar to 'default' in switch-case) Key Components:

• match statement: The equivalent of the switch keyword in other languages.
• case clauses: These represent the individual cases you want to check against, similar to case in switch-case.
• Wildcard (_): Acts as the default case, covering any values that don’t match the specified patterns.

Example: Basic Pattern Matching

Let’s start with a simple example of using match to simulate a switch-case statement that handles different types of user inputs.

Pythondef process_command(command): match command: case "start": return "Starting the system..." case "stop": return "Stopping the system..." case "restart": return "Restarting the system..." case _: return "Unknown command." # Testing the function print(process_command("start")) # Output: Starting the system... print(process_command("pause")) # Output: Unknown command.

In this example:

• The match statement checks the value of command.
• Depending on the matched value, the corresponding message is returned.
• The wildcard (_) case handles any input that doesn’t match the predefined commands, acting as a fallback or default case.

Advanced Pattern Matching

The match statement in Python 3.10 is not limited to simple value matching. It supports more complex patterns, including:

1. Matching Data Structures

You can use pattern matching with lists, tuples, and dictionaries.

Pythondef analyze_shape(shape): match shape: case ("circle", radius): return f"Circle with radius {radius}" case ("rectangle", width, height): return f"Rectangle with width {width} and height {height}" case ("square", side): return f"Square with side {side}" case _: return "Unknown shape" # Testing the function print(analyze_shape(("circle", 5))) # Output: Circle with radius 5 print(analyze_shape(("rectangle", 4, 6))) # Output: Rectangle with width 4 and height 6

2. Matching with Conditions (Guards)

You can add conditions to cases using if statements, known as “guards”.

Python 0: return "Negative number" case n if n == 0: return "Zero" case n if n > 0: return "Positive number" # Testing the function print(categorize_number(-5)) # Output: Negative number print(categorize_number(0)) # Output: Zero print(categorize_number(10)) # Output: Positive number" style="color:#D4D4D4;display:none" aria-label="Copy" class="code-block-pro-copy-button">def categorize_number(number): match number: case n if n < 0: return "Negative number" case n if n == 0: return "Zero" case n if n > 0: return "Positive number" # Testing the function print(categorize_number(-5)) # Output: Negative number print(categorize_number(0)) # Output: Zero print(categorize_number(10)) # Output: Positive number

3. Combining Patterns

You can also combine multiple patterns in a single case using the | (or) operator.

Pythondef get_day_type(day): match day: case "Saturday" | "Sunday": return "Weekend" case "Monday" | "Tuesday" | "Wednesday" | "Thursday" | "Friday": return "Weekday" case _: return "Invalid day" # Testing the function print(get_day_type("Sunday")) # Output: Weekend print(get_day_type("Monday")) # Output: Weekday print(get_day_type("Funday")) # Output: Invalid day

When to Use match Over if-elif-else

While you can still use if-elif-else statements, match provides a cleaner and more readable alternative when dealing with multiple conditions. It’s especially useful when:

• You have a large number of conditions to check.
• You want to match complex data structures.
• You need to execute different code blocks based on the structure of data, not just its value.

By mastering this new feature, you can write cleaner, more maintainable code that can easily adapt to complex logic scenarios.

As you start integrating match into your code, you’ll likely find many situations where it simplifies your conditional logic, making your Python code not only more efficient but also more Pythonic.

From Drupal Forge trial sites to persistent hosting

Due to concerns that the launch button would funnel business to one vendor at the expense of others, Starshot leadership announced that the launch button would use WebAssembly to run site trials in a user’s browser without external hosting. This approach has the advantages of being able to run Drupal off line and not needing anyone to pay for hosting. However, it is technically challenging and will not work for everyone. Sites running in WebAssembly cannot be visited by others and are not persistent.

A shiny new release 0.2.4 of pkgKitten arrived on CRAN earlier, and has also been been uploaded to Debian. pkgKitten makes it simple to create new R packages via a simple function invocation. A wrapper kitten.r exists in the littler package to make it even easier.

This release contains several improvements to the (optional) setup of the (wonderful) tinytest package, now supports the (now mandatory) ‘Authors@R’ and polished a few aspect around the package repository and continuous integrations.

The set of changes follows.

Changes in version 0.2.4 (2024-08-30)

• The .Rbuildignore stanza now includes .github

• The support of and usage illustrations of tinytest are much enhanced (Paul Hudor in #18 adressing #19 and #20)

• The .gitignore file now includes C++ related files

• Improvements and polish to badges and continuous integration

• The DESCRIPTION file now contains an Authors@R entry

More details about the package are at the pkgKitten webpage, the pkgKitten docs site, and the pkgKitten GitHub repo.

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

If you like this or other open-source work I do, you can sponsor me at GitHub.

It (was) that time of year again - last weekend we hosted a bunch of nice people at our place in Cambridge for the annual Debian UK OMGWTFBBQ!

Lots of friends, lots of good food and drink. Of course lots of geeky discussions about Debian, networking, random computer languages and... screws? And of course some card games to keep us laughing into each night!

Many thanks to a number of awesome friendly people for again sponsoring the important refreshments for the weekend. It's hungry/thirsty work celebrating like this!

The DropTimes presents a detailed FAQ explaining the transition from 'Drupal' to 'Drupal CMS.' Discover the reasons behind this branding decision, its impact on the Drupal ecosystem, and what it means for developers and users alike.

DebConf24 was held in Busan, South Korea, from July 28th to August 4th 2024 and preceded by DebCamp from July 21st to July 27th. This was my second IRL DebConf (DC) and fourth one in total. I started in Debian with a DebConf, so its always an occassion when one happens.

This year again, I worked in fundraising team, working to raise funds from International sponsors. We did manage to raise good enough funding, albeit less than budgeted. Though, the local Korean team was able to connect and gather many Governmental sponsors, which was quite surprising for me.

I wasn’t seriously considering attending DebConf until I discussed this with Nilesh. More or less his efforts helped push me through the whole process. Thanks Nilesh for this. In March, I got my passport and started preparing documents for South Korean visa. It did require quite a lot of paper work but seeing South Koreas’s fresh passport visa rejection rate, I had doubts about visa acceptance. The visa finally got approved, which could be attributed to great documentation and help from DebConf visa team. This was also my first trip outside India, and this being to DebConf made many thing easy. Most stuff were documentated on DebConf website and wiki. Asking some query got immediate responses from someone in the DebConf channels.

We then booked a direct flight from Delhi, reaching Seoul in the morning. With good directions from Sourab TK who had reached Seoul a few hours earlier, we quickly got Korean Won, local SIM and T Money card (transportation card) and headed towards Seoul by AREX, airport metro. We spent the next two days exploring Seoul, which is huge. It probably has the highest number of skyscrappers I have ever seen. The city has good mix modern and ancient culture. We explored various plaes in Seoul including Gyeongbokgung Palace, Statue of King Sejong, Bukchon Hanok village, N Seoul Tower and various food markets which were amazing.

A Street in Seoul

Next, we to headed to Busan for DebConf using KTX (Korean high speed rail). (Fun fact, slogan for City of Busan is “Busan is Good”.) South Korea has good network of frequently running high speed trains. We had pre-booked our tickets because despite the frequency, trains were sold out most of the times. KTX ride was quite smooth, despite travelling at 300 Kmph at times through Korean countryside and long mountain tunnels.

PKNU Entrance

The venue was for DebConf was Pukyong National University (PKNU), Daeyeon Campus. PKNU had two campuses in the Busan and some folks ended up in wrong campus too. With good help and guidance from front desk, we got our dormitery rooms assigned. Dorms here were quite different ie:

• Rooms had heated floors. It seems to snow in Busan.
• Each area was had card based access. There was a seperate card for laundry too.
• Rooms had announcement systems right inside the room, though we couldn’t decipher any announcement as all of them were in Korean.
• Each room was provided with a dedicated access point and own SSID inside the room.

View from Dorm Room

Settling in was easy and we started meeting familiar folks after almost an year. The long conversations started again. Everyone was excited for DebConf.

Like everytime, first day was full of action (and chaos). Meet and greet, voluneteers checkin, video team running around and fixing stuff and things working (or not). There were some interesting talks and sponsors stalls . After day one, things more or less settled down. I again volunteered for video team stuff and helped in camera operations and talk directions which is always fun. As the tradition applies, saw few talks live on stream too sitting in the dorm room during the conf, which is always fun, when too tired to get ready and go out.

From Talk Director's chair

DebConf takes care of food needs for vegan/vegetration folks well, of which I’m one. I got to try different food items which was quite an experience. Tried using chopsticks again which didn’t work, which I later figured that handling metal ones were more difficult. We had late night ramens and wooden chopsticks worked perfectly. One of the days, we even went out to an Indian resturarent to have some desi aloo paratha, paneer dishes, samosas and chai (milk tea). I wasn’t particularyly craving desi food but wasn’t able to get something according to my taste so went there.

As usual Bits from DPL talk was packed

For daytrip, I went to Ulsan. San means mountains in Korean. Ulsan is a port city with many industries including Hyundai car factory, petrochemical industry, paint industry, ship building etc. We saw bamboo forest, Ulsan tower (quite a view towards Ulsan port), whale village, Ulsan Onggi Museum and the sea (which was beautiful).

Amongst the sponsors, I was most interested in our network sponsors folks who were National research and education networks (NREN) here. We had two network sponsors, KOREN and KREONET, thanks to efforts by local team. Initially it was discussed that they’ll provide 20G uplink each, so 40G in total, which was whopping but by the time the closing talk happened, we got to know we had 200G uplink to the Internet. This was massive update to last year where we had 1G main and 100M backup link. 200G wasn’t what is required but it was massive capacity and IIRC from the talk, we peaked at around 500M in usage but it’s always fun have astronomical amount of bandwidth for bragging rights ;)

Various mascots in attendence

Now lets talk about things I found interesting about South Korea in general:

• Convience stores were everywhere, one could see same brand stores less than kilometer apart. We had even had two of them (GS25(s)), a road cross away too. These places were well stocked with almost everything even alcohol.
• There were wide footpaths and pedestrian friendly policies.
• Public transport and intra modal transfer is convient and easy to figure. Each metro station connects to multiple nearby buildings through underground walkways and one never had to go out in the sun (in hot and humid weather). Also Seoul and Busan metro networks were massive. Same T money card worked for buses (almost hop on, tap and hop off at your destination), metros and even cabs.
• South Korea pays special attention to maintaining their historical and cultural buildings. These venues had informational brochures in Korea, English, Japanese and Chinese.
• We got constant stream of “Public safety alerts” on our phones. Some phones even read them aloud for heatwaves and rains warnings, all in Korean.
• Trash was segrated at source everywhere.
• Public, high speed WIFI was omni-present in malls, public transport, airport etc. In metro, each coach had access points from all three telecom providers (SK Telecom, KT and LG U+) which also had almost similar voice and data plans.
• Police personals were quite helpful despite the language issue.
• Not many folks here are comfortable in English but one can always make use of various mobile translation apps.
• Cards are accepted everywhere and there’re too many of these cards ;)
• Food situation was bit difficult for me as a vegetration. We always have vegan/veg food in DebConf but outside, this whole concept doesn’t seem to exist here.
• I couldn’t find any public speedtest servers inside Korea. All my fast.com/speedtest.net servers were located either Hong Kong, Singapore, Japan and even in United States. On the very last day, I got a speedtest servers in Seoul, inside SK Telecom.

If one has to get the whole DebConf experience, it’s better to attend DebCamp as well because that’s when you can sit and interact with everyone better. As DebConf starts, everyone gets busy in various talks and events and things take a pace. DebConf days literally fly. This year, attending DebConf in person was a different experience. Attending DebConf without any organisational work/stress so was better and I was able to understand working of different Debian team and workflows better while also identified a few where I would like to join and help. A general conclusion was that almost almost all Debian team needs more folks to help out. So if someone want to join, they can probably reach out to team and they would be able to onboard new folks. Though this would require some patience. Kudos to the Korean team who were able to pull of this event under this tight timeline and thanks for all the hospitality.

57th issue of Andrei Neagoie's must-read monthly Python Newsletter

Review: Thornhedge, by T. Kingfisher

Publisher: Tor Copyright: 2023 ISBN: 1-250-24410-2 Format: Kindle Pages: 116

Thornhedge is a fantasy novella by T. Kingfisher, the pen name that Ursula Vernon uses for her adult writing. It won the 2024 Hugo Award for best novella. No matter how much my brain wants to misspell the title, it is a story about a hedge, not a Neolithic earthwork.

The fairy was the greenish-tan color of mushroom stems and her skin bruised blue-black, like mushroom flesh. She had a broad, frog-like face and waterweed hair. She was neither beautiful nor made of malice, as many of the Fair Folk are said to be.

There is a princess asleep in a tower, surrounded by a wall of thorns. Toadling's job is to keep anyone from foolishly breaking in. At first, it was a constant struggle and all that she could manage, but with time, the flood of princes slowed to a trickle. A road was built and abandoned. People fled. There was a plague. With any luck, the tower was finally forgotten.

Then a knight shows up. Not a very rich knight, nor a very successful knight. Just a polite and very persistent knight who wants to get into the tower that Toadling does not want him to get into.

As you might have guessed, this is a Sleeping Beauty retelling. As you may have also guessed from the author, or from the cover text that says "not all curses should be broken," this version is a bit different. How and why it departs from the original is a surprise that slowly unfolds over the course of the story, in parallel to a delicate, cautious, and delightfully kind-hearted conversation between the knight and the fairy.

If you have read a T. Kingfisher story before, particularly one of her fractured fairy tales, you know what to expect. Toadling is one of her typical well-meaning, earnest, slightly awkward protagonists who is just trying to do the right thing in a confusing world full of problems and dangers. She's constantly overwhelmed and yet she keeps going, because what else is there to do. Like a lot of Kingfisher's writing, it's a story about quiet courage from someone who doesn't consider herself courageous. One of the twists this time is that the knight is a character from a similar vein: doggedly unwilling to leave any problem alone, but equally determined to try to be kind. The two of them together make for a story with a gentle and rather melancholy tone.

We do, eventually, learn the whole backstory of the tower, the wall of thorns, and Toadling. There is a god, a rather memorable one, who is frustratingly cryptic in the way that gods are. There are monsters who are more loving than most humans. There are humans who turn out to be surprisingly decent when it matters. And, like most of Kingfisher's writing, there is a constant awareness of how complicated the world is, how full it is of people who are just trying to get through each day, and how heavy of burdens people can shoulder when they don't see another way.

This story pulled me right in. It is not horror, although there are a few odd bits like there always are in Kingfisher stories. Your largest risk as a reader is that it might make you cry if stories about earnest people doing their best in overwhelming situations hit you that way. My primary complaint is that there was nowhere near enough ending for me. After everything I learned about the characters, I wanted to spend some time with them outside of the bounds of the story. Kingfisher points the reader in a direction and then leaves the rest to your imagination, and I can see why she chose that story construction, but I wanted more catharsis than I got.

That complaint aside, this is quintessential T. Kingfisher, and I am unsurprised that it won a Hugo. If you've read any of her other fractured fairy tales, or the 2023 Hugo winner for best novel, you know the sort of stories she tells, and you probably know whether you will like this. I am one of the people who like this.

Warning: If you're not into meat, you might want to skip the rest of this...

This year, I turned 50. Wow. Lots of friends and family turned up to help me celebrate, with a BBQ (of course!). I was very grateful for a lovely set of gifts from those awesome people, and I have a number of driving experiences to book in the next year or so. I'm going to have so much fun driving silly cars on and off road!

However, the most surprising gift was something totally different - a full-day course of hands-on pork butchery. I was utterly bemused - I've never considered doing anything like this at all, and I'd certainly never talked to friends about like it either. I was shocked, but in a good way!

So, two weekends back Jo and I went over to Empire Farm in Somerset. We stayed nearby so we could be ready on-site early on Sunday morning, and then we joined three other people doing the course. Jo was there to observe, i.e. to watch and take (lots of!) pictures.

I can genuinely say that this was the most fun surprise gift I've ever received! David Coldman, the master butcher working with us, has been in the industry for many years. He was an excellent teacher, showing us everything we needed to know and being very patient with us when we needed it. It was great to hear his philosophy too - he only uses the very best locally-sourced meat and focuses on quality over quantity. He showed us all the different cuts of pork that a butcher will make, and we were encouraged to take everything home - no waste here!

At the beginning of the day, we each started with half a pig. Over the next several hours, we steadily worked our way through a series of cuts with knife and saw, making the remaining pig smaller and smaller as we went.

We finished the day with three sets of meat. First, a stack of vacuum-packed joints, chops and steaks ready for cooking and eating at home. Second: a box of off-cuts that we minced and made into sausages at the end of the day. Finally: a bag of skin and bones. Our friend's dog got some of the bones, and Jo turned a lot of the skin into crackling that we shared with friends at the OMGWTFBBQ the next weekend.

This was an amazing day. Massive thanks to my good friend Chris Walker for suggesting this gift. As I told David on the day: this was the most fun surprise gift I've ever received. Good hands-on teaching in a new craft is an incredible thing to experience, and I can't recommend this course highly enough.

In this episode, we pulled out a new tool. We spent the session using Kamal, a tool to deploy web apps directly to servers. Kamal offers a complete tool set to get apps running on bare metal or cloud machines. We played with the tool to see how far we go to get an app deployed to a new server.

The diffoscope maintainers are pleased to announce the release of diffoscope version 277. This version includes the following changes:

[ Sergei Trofimovich ] * Don't crash when attempting to hashing symlinks with targets that point to a directory.

PyCharm now provides two color-scheme options for the table heatmaps in the Data View tool window: the Diverging and Sequential color schemes.

The Diverging color scheme emphasizes variation relative to a norm. It consists of two contrasting colors that deviate from a central value in two opposite directions.

The Sequential color scheme consists of a single color or a range of closely related colors that vary in intensity.

You can apply the heatmap color schemes to the whole table or to each column separately, or you can use coloring only for Boolean values.

Python 3.13

PyCharm now recognizes TypeIs syntax, providing proper type inference and code completion for user-defined narrowed functions. As part of Python 3.13 support, the IDE is now also aware of ReadOnly keys in TypedDict and warns you if something is assigned to a ReadOnly member.

Dries Buytaert announced recently that the product name for the result of the Drupal Starshot Initiative will be Drupal CMS. Exciting! Activities on features for Drupal CMS are divided into tracks - a set of deliverables focused to provide valuable solutions for different parts of the product strategy.

Let’s see what’s cooking in the Drupal CMS kitchen as since the announcement of the track leads, quite some work has been done. We are happy to share a brief overview to highlight the progress made!

The Events Track has been busy with transferring the Events recipe to the Drupal CMS and now we’ve got the beginnings of an event system. As with all the Drupal CMS components, the ultimate plan is for each one to be available as its own project, but at the same time all be developed within the same repo. 

The Data Privacy / Compliance Track is busy developing a survey for the international audience. We are looking forward to sharing it with the community very soon.

The Trial Experience Track in coordination with the Drupal Association has devised a solution to leverage GitLab Pages. After checking in with the rest of the Drupal CMS team, it was decided the trial codebase would be added to the monolithic repository. You can find more details at the dedicated blog post by Matt Glaman.

The Starshot Demo Design System initiative is supporting the Experience Builder demo next month by providing Drupal-branded components within a design system theme. The team has made excellent progress and needs more help in the next two weeks to test components within Experience Builder. Learn how to get involved!

The SEO Track managed to add Basic SEO recipe to Drupal CMS. This recipe will be applied by default, is idempotent (can be applied multiple times), and sets the simple best practices configuration we feel every site needs. The team is continuing to work to define an advanced SEO recipe that we will propose to be optional that has more tools for optimizing for search engines.

The Advanced Search Track has drafted a proposal for the track. It is being reviewed by the leadership team and the idea is to provide a recipe for at least two different approaches and collect community feedback. We expect this to happen in September so stay tuned!

The Media Management Track is undertaking discovery to gather common practices and new insights that will lead to a proposal for the features and recipes for media in early versions of Drupal CMS. The track will also propose how improvements and innovations could look for media beyond the launch of Drupal CMS. Tony Barker has created a survey as part of the discovery and welcomes the community to provide their thoughts and feelings on media in Drupal using this form.

We are observing the progress each track team is making with excitement and will keep you up to date on upcoming developments!
