In mid-March we released a big bug fix update—elementary OS 8.0.1—and since then we’ve been hard at work on even more bug fixes and some new exciting features that I’m excited to share with you today! Read ahead to find out what we’ve released recently and what you can help us test in Early Access. Quick Settings Quick Settings has a new “Prevent Sleep” toggle Leo added a new “Prevent Sleep” toggle. This is useful when you’re giving a presentation or have a long-running background task where you want to temporarily avoid letting the computer go to sleep on its normal schedule. We also fixed a bug where the “Dark Mode” toggle would cancel the dark mode schedule when used. We now have proper schedule snoozing, so when you manually toggle Dark Mode on or off while using a timed or sunset-to-sunrise schedule, your schedule will resume on the next schedule change instead of being canceled completely. Vishal also fixed an issue that caused some apps to report being improperly closed on system shutdown or restart and on the lock screen we now show the “Suspend” button rather than the “Lock” button. System Settings Locale settings has a fresh layout thanks to Alain with its options aligned more cleanly and improved links to additional settings. Locale Settings has a more responsive design We’ve also added the phrase “about this device” as a search term for the System page and improved interface copy when a restart is required to finish installing updates based on your feedback. Plus, Stanisław improved stylus detection in Wacom settings preventing a crash when no stylus is found. AppCenter We now show a small label next to the download button for apps which contain in-app purchases. This is especially useful for easily identifying free-to-play games or alt stores like Steam or Heroic Games Launcher. AppCenter now shows when apps have in-app purchases Plus, we now reload app icons on-the-fly as their data is processed, thanks to Italo. That means you’ll no longer get occasionally stuck with an AppCenter which shows missing images for app’s who have taken a bit longer than usual to load. Get These Updates As always, pop open System Settings → System on elementary OS 8 and hit “Update All” to get these updates plus your regular security, bug fix, and translation updates. Or set up automatic updates and get a notification when updates are ready to install! Early Access Our development focus recently has been on some of the bigger features that will likely land for either elementary OS 8.1 or 9. We’ve got a new app, big changes to the design of our desktop itself, a whole lot of under-the-hood cleanup, and the return of some key system services thanks to a new open source project. Monitor We’re now shipping a System Monitor app by default By popular demand—and thanks to the hard work of Stanisław—we have a new system monitor app called “Monitor” shipping in Early Access. Monitor provides usage information for your processor, GPU, memory, storage, network, and currently running processes. You can optionally see system information in the panel with Monitor You can also optionally get a ton of glanceable information shown in the panel. There’s currently a lot of work happening to port Monitor to GTK4 and improve its functionality under the Secure Session, so make sure to report any issues you find! Multitasking The Dock is getting a workspace switcher Probably the biggest change to the Pantheon shell since its early inception, the Dock is getting a new workspace switcher! The workspace switcher works in a familiar way to the one you may have seen in the Multitasking View: Your currently open workspaces are represented as tiles with the icons of apps running on them; You can select a workspace to switch to it; You can drag-and-drop workspaces to rearrange them; And you can use the “+” button to create a new blank workspace. One new trick however is that selecting the workspace you’re already on will launch Multitasking View. The new workspace switcher makes it so much more accessible to multitask with just the mouse and get an overview of your workflows without having to first enter the Multitasking View. We’re really excited to hear what people think about it! You can close apps from Multitasking View by swiping up Another very satisfying feature for folks using touch input, you can now swipe up windows in the Multitasking View to close them. This is a really familiar gesture for those of us with Android and iOS devices and feels really natural for managing a big stack of windows without having to aim for a small “x” button. GTK4 Porting We’ve recently landed the port of Tasks to GTK4. So far that comes with a few fixes to tighten up its design, with much more possible in the future. Please make sure to help us test it thoroughly for any regressions! Tasks has a slightly tightened up design We’re also making great progress on porting the panel to GTK4. So far we have branches in review for Nightlight, Bluetooth, Datetime, and Network indicators. Power, Keyboard, and Quick Settings indicators all have in-progress branches. That leaves just Applications, Sound, and Notifications. So far these ports don’t come with major feature changes, but they do involve lots of cleaning up and modernizing of these code bases and in some cases fixing bugs! When the port is finished, we should see immediate performance gains and we’ll have a much better foundation for future releases. You can follow along with our progress porting everything to GTK4 in this GitHub Project. And More When you take a screenshot using keyboard shortcuts or by secondary-clicking an app’s window handle, we now send a notification letting you know that it was succesful and where to find the resulting image. Plus there’s a handy button that opens Files with your screenshot pre-selected. We’re also testing beaconDB as a replacement for Mozilla Location Services (MLS). If you’re not aware, we relied on MLS in previous versions of elementary OS to provide location information for devices that don’t have a GPS radio. Unfortunately Mozilla discontinued the service last June and we’ve been left without a replacement until now. Without these services, not only did maps and weather apps cease to function, but system features like automatic timezone detection and features that rely on sunset and sunrise times no longer work properly. beaconDB offers a drop-in replacement for MLS that uses Wireless networks, bluetooth devices, and cell towers to provide location data when requested. All of its data is crowd-sourced and opt-in and several distributions are now defaulting to using it as their location services data provider. I’ve set up a small sponsorship from elementary on Liberapay to support the project. If you can help support beaconDB either by sponsoring or providing stumbler data, I’d highly encourage you to do so! Sponsors At the moment we’re at 23% of our monthly funding goal and 336 Sponsors on GitHub! Shoutouts to everyone helping us reach our goals here. Your monthly sponsorship funds development and makes sure we have the resources we need to give you the best version of elementary OS we can! Monthly release candidate builds and daily Early Access builds are available to GitHub Sponsors from any tier! Beware that Early Access builds are not considered stable and you will encounter fresh issues when you run them. We’d really appreciate reporting any problems you encounter with the Feedback app or directly on GitHub.
It’s been a little over 100 days since elementary OS 8 was released, and we’re proud to announce another round of updates, including a fresh new download. We’ve been hard at work this winter addressing issues that you reported and we’ve added a couple new creature comforts along the way. This bug fix release also includes the latest Ubuntu LTS Hardware Enablement Kernel, so it’s worth checking out if you downloaded OS 8.0 and it disagreed with your hardware. AppCenter We now properly use dark mode brand colors and dark mode screenshots thanks to Italo. Plus, when developers provide screenshots for multiple desktop environments, we now prefer the ones intended for our desktop environment, Pantheon. We support the new <Developer> Appstream tag, thanks to Juan. And we now support the contribute URL type. AppCenter now shows dark mode screenshots when available Italo also fixed some issues with release notes overflowing out of their container, and we slightly redesigned the release notes window in the Updates page. He also addressed a few other issues in the Updates page that could occur while things were being updated or refreshed and made sure AppCenter recovers gracefully when its cache is emptied. Release notes dialogs have been slightly redesigned Search is also much faster thanks to Leonhard. And for developers, Ryo fixed loading your local metadata for testing with the --load-local terminal option. Files & Terminal Jeremy fixed another half-dozen reported issues in Files, including an issue that prevented entering file paths in search mode, an issue that prevented scrolling after deleting files, and an issue where files would disappear when dropped on an unmounted drive. The New file submenu now respects the hierarchy of folders in Templates. We now also respect the admin:// uri protocol for opening a path as an administrator, and Files is now styled correctly when run as administrator. He also fixed an issue where Terminal tabs took multiple clicks to focus, and an issue where keyboard shortcuts stopped working for tabs that had been dragged into their own new window. Plus, file paths and names are also now properly quoted when drag-and-dropped from Files into Terminal. System Settings System Settings now allows configuring its notifications in System Settings → Notications. So you can turn off bubbles if you don’t want to receive notifications about updates, for example. We’ll also no longer automatically download updates when on metered connections and send a notification instead, thanks to Leonhard. Plus we no longer check for updates in Demo Mode. Updates now show their download size and you can see progress towards our monthly sponsorship goal In System, Vishal made sure we show how large an update will be before downloading it and that we skip held-back packages—such as phased or staged updates—when preparing the updates bundle so that it will more reliably succeed. Alain added a progress bar while downloading. And Ryo made sure the last refresh time is more accurate when no updates are available. Alain also added a new progress bar that represents how close we are to meeting our monthly sponsorship goal. In Applications, you can now disallow notifications access. This is especially useful for apps which use the notifications portal, but don’t properly report their notification usage and can’t be controlled in the Notifications settings page. Reign in apps that don’t appear in Notifications settings In Network there are two new settings: whether a network should be automatically connected to when available and whether to reduce background data usage when connected to that network. Disable autoconnect or mark a network as metered We also updated the pointer icons in Mouse & Touchpad settings and the checkmarks in Locale settings will now respect your chosen accent color. Plus settings pages with sidebars now remember the width you adjusted them to, thanks to Alain. Installation & Onboarding David fixed a crash with certain partitioning schemes in the Installer’s custom install view. And the Encryption step was redesigned to fit on a single page, solving an issue with confusing navigation. Plus, onboarding will now always stay centered on the screen, even when resized. Panel & Quick Settings Ilya fixed an issue with the panel height when using the Classic session and HiDPI displays. The app context menu in the Applications menu now shows a “Keep in Dock” checkbox, just like in the Dock thanks to Stella. In the Power menu, we now show the device model if available, and avoid erroneously showing an empty battery icon thanks to Alain. In the Sound menu, Dmitry fixed loading album art from certain apps like Google Chrome, and we fixed an issue where player icons could become too large. See who else is logged in and quickly switch accounts from Quick Settings In Quick settings, Leonhard fixed an issue with performing updates while shutting down. And Alain added a new page where you can see which other people are logged in and quickly switch between accounts. Dock Leo added a bit more spacing between launchers and their running indicators, and fixed an issue where larger icons could be clipped at the peak of their bounce animation. Apps who don’t notify on startup will no longer bounce in the dock indefinitely, thanks to Leonhard. We fixed an issue where the dock would still receive click events while hidden in the Classic session. Plus the dock now has an opaque style when “Panel Translucency” is turned off in System Settings → Desktop → Dock & Panel. Window Manager We have another huge release of our window manager thanks to Leonhard and Leo. This release fixes five potential crashes, over a dozen reported issues, fixes related to both the Classic and Secure sessions, issues related to HiDPI, and more, plus performance improvements. It’s worth reading the full release notes on GitHub if you have been waiting for the fix for a specific issue. And More OS 8.0.1 includes the latest long-term support Hardware Enablement stack from Ubuntu, including Linux 6.11. This brings improved performance for AMD processors, support for Intel “Lunar Lake” processors, and filesystem performance improvements in some cases. Plus support for certain webcams, USB network devices, joysticks, and more. Leo fixed an issue where connecting Bluetooth devices could cause the Lock Screen to freeze. You can now close the captive network assistant with the keyboard shortcut Ctrl + Q, thanks to Stanisław. And Alain fixed copying screenshots to the clipboard. We fixed an issue where wired network connections could fail to connect due to a change in Ubuntu. We’re pursuing this issue upstream and working on a way to ship the fix as an update, but for now fixing this issue requires either manual intervention through Terminal or a reinstall. We also now pre-install an AppArmor profile that fixes a number of Flatpak-related issues like not being to install certain runtime updates or apps not launching in the guest session or Demo mode. Special thanks to Uncle Tallest for investigating this issue and helping folks in our Discord who ran into it. And of course this release comes with a ton of translation updates! Special thanks to our hard-working internationalization community and especially Ryo who fixed a number of issues with things that couldn’t be localized properly in the previous release.

It’s only been a little over 2 weeks since we released elementary OS 8, but we’re already back with updates just in time for the holidays! Terminal The headliner this month is Terminal which comes with a bunch of fixes and new features thanks to Jeremy. It now uses the more modern tab bar widget you’re used to from Web, Files, and Code. There’s an overlay bar that shows the current zoom level when it changes. We do a better job of handling URIs which contain spaces. And we now show unsafe paste warnings for Drag n Drop operations. Plus, we now show the unsafe paste warning for more commands like doas thanks to Elsie and there’s a new option in the gear menu to toggle unsafe paste alerts thanks to Stella and Charlie. Michal upped the contrast for gray in our default style and Igor made sure we focus the relevant tab when notifications are clicked. Plus, we now replace notifications from the same tab and withdraw notifications when a tab is focused, so your notification center should be a lot less noisy. This release was really a group effort with several new contributors, so major shoutouts to everyone who worked on it! AppCenter AppCenter will use Dark Mode screenshots when available Thanks to Italo, AppCenter will now use provided dark mode screenshots and brand colors when developers provide them. Plus, he addressed a visual bug with release notes. And Juan added support for the latest Appstream Developer tag, so we’re staying up on standards. Window Manager & Dock In the Window Manager, Leo fixed an issue where the dock could sometimes still be clicked when hidden in the Classic session, while Leonhard contributed some performance improvements. In the Dock, Leonhard made sure launcher bounces don’t run too long for apps that don’t notify on startup. Leo fixed an issue where launchers with large icons could become clipped while they bounce and made sure running indicators have a bit more room to breath. Plus the dock now also respects the “Panel Translucency” setting, making it completely solid when requested for added contrast. System Settings Alain added some visual polish to the System view as well as a new progress bar that represents how close we are to meeting our monthly sponsorship goal. Plus Leonhard made sure automatic updates won’t download on metered networks, and we avoid checking for system updates altogether in Demo Mode. We now show monthly funding goal progress right in System Settings You can now prevent Apps from sending notifications from Applications → Permissions, even for apps that don’t report their notification usage in Notification settings. and the check mark next to the current language in Language & Region settings will now follow your accent color thanks to Leo. Installation & Onboarding David fixed a crash with certain partitioning schemes in the Installer’s custom install view, and the encrypt view was simplified. Onboarding will now always stay centered on the screen, even when resized. Icon Browser A new version of the Icon Browser for app developers is available in AppCenter that includes the latest icons for Platform 8 as well as a quick button for copying code snippets thanks to Ryo. And we now focus the search automatically when you start typing, thanks to Alain. And More You can now close the captive network assistant with the keyboard shortcut Ctrl + Q, thanks to Stanisław. Alain fixed copying screenshots to the clipboard. And there a ton of translation updates, especially including traditional Chinese thanks to Kisaragi.

This month’s update is fairly brief since a lot of what we did last month was minor bug fixes, regression testing, updating metadata, taking screenshots, and releasing packages. We’re getting down to the last few items before we can release elementary OS 8. Read ahead to find out more! OS 7 Updates Just a couple of small OS 7 updates this month! Ryan backported a fix for an issue in AppCenter where the updates page would continue to show the loading screen after it was finished loading. And the latest Network Indicator was released and now shows cellular modems as toggle buttons like it does with other devices. Cellular modems now show as toggle buttons OS 8 Updates Continuing on with our work to vastly improve screen reader support this cycle, Leo implemented the accessibility interface in the Alt + Tab window switcher! Leonhard added a new option to the system shutdown dialog so you can choose to skip a pending update, even when automatic updates are enabled. You can choose to skip updates when shutting down or restarting If you have a mixed-dpi setup—like a HiDPI laptop or tablet and a LoDPI external monitor—You can now set per-display scaling in the Secure Session thanks to Leonhard. And power modes can also now be quickly changed from the power indicator thanks to Subhadeep. Power modes now appear in the power indicator Release Planning Last month we finished releasing nearly every component that makes up elementary OS—over 80 packages. The only thing left is the Login & Lock Screen which is blocked by two small issues. We also have just two more OS patches to complete. Once these issues are resolved and the Login & Lock Screen has a package release, we can build release-candidate images of elementary OS 8 from the stable updates channel—and these builds will be available to Sponsors in Early Access right away. There’s still a couple more issues we want to try to solve before the final public OS 8 release, but we’re very close! As always you can follow along with our progress towards the release of OS 8 in this GitHub project. When this project board is empty, it’s public release time!

Having spent four decades as a programmer in various industries and situations, I know that modern software development processes are far more stressful than when I started. It's not simply that developing software today is more complex than it was back in 1981. In that early decade, none
In previous articles, we saw how to use “real” UART, and looked into the trick used by Arduino to automatically reset boards when uploading firmware. Today, we’ll look into how Espressif does something similar, using even more tricks. “Real” UART on the Saola As usual, let’s first simply connect the UART adapter. Again, we connect … Continue reading Espressif’s Automatic Reset → The post Espressif’s Automatic Reset appeared first on Quentin Santos.
I started writing this early last week but Real Life Stuff happened and now you're getting the first-draft late this week. Warning, unedited thoughts ahead! New Logic for Programmers release! v0.9 is out! This is a big release, with a new cover design, several rewritten chapters, online code samples and much more. See the full release notes at the changelog page, and get the book here! Write the cleverest code you possibly can There are millions of articles online about how programmers should not write "clever" code, and instead write simple, maintainable code that everybody understands. Sometimes the example of "clever" code looks like this (src): # Python p=n=1 exec("p*=n*n;n+=1;"*~-int(input())) print(p%n) This is code-golfing, the sport of writing the most concise code possible. Obviously you shouldn't run this in production for the same reason you shouldn't eat dinner off a Rembrandt. Other times the example looks like this: def is_prime(x): if x == 1: return True return all([x%n != 0 for n in range(2, x)] This is "clever" because it uses a single list comprehension, as opposed to a "simple" for loop. Yes, "list comprehensions are too clever" is something I've read in one of these articles. I've also talked to people who think that datatypes besides lists and hashmaps are too clever to use, that most optimizations are too clever to bother with, and even that functions and classes are too clever and code should be a linear script.1. Clever code is anything using features or domain concepts we don't understand. Something that seems unbearably clever to me might be utterly mundane for you, and vice versa. How do we make something utterly mundane? By using it and working at the boundaries of our skills. Almost everything I'm "good at" comes from banging my head against it more than is healthy. That suggests a really good reason to write clever code: it's an excellent form of purposeful practice. Writing clever code forces us to code outside of our comfort zone, developing our skills as software engineers. Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you [will get excellent debugging practice at exactly the right level required to push your skills as a software engineer] — Brian Kernighan, probably There are other benefits, too, but first let's kill the elephant in the room:2 Don't commit clever code I am proposing writing clever code as a means of practice. Being at work is a job with coworkers who will not appreciate if your code is too clever. Similarly, don't use too many innovative technologies. Don't put anything in production you are uncomfortable with. We can still responsibly write clever code at work, though: Solve a problem in both a simple and a clever way, and then only commit the simple way. This works well for small scale problems where trying the "clever way" only takes a few minutes. Write our personal tools cleverly. I'm a big believer of the idea that most programmers would benefit from writing more scripts and support code customized to their particular work environment. This is a great place to practice new techniques, languages, etc. If clever code is absolutely the best way to solve a problem, then commit it with extensive documentation explaining how it works and why it's preferable to simpler solutions. Bonus: this potentially helps the whole team upskill. Writing clever code... ...teaches simple solutions Usually, code that's called too clever composes several powerful features together — the "not a single list comprehension or function" people are the exception. Josh Comeau's "don't write clever code" article gives this example of "too clever": const extractDataFromResponse = (response) => { const [Component, props] = response; const resultsEntries = Object.entries({ Component, props }); const assignIfValueTruthy = (o, [k, v]) => (v ? { ...o, [k]: v } : o ); return resultsEntries.reduce(assignIfValueTruthy, {}); } What makes this "clever"? I count eight language features composed together: entries, argument unpacking, implicit objects, splats, ternaries, higher-order functions, and reductions. Would code that used only one or two of these features still be "clever"? I don't think so. These features exist for a reason, and oftentimes they make code simpler than not using them. We can, of course, learn these features one at a time. Writing the clever version (but not committing it) gives us practice with all eight at once and also with how they compose together. That knowledge comes in handy when we want to apply a single one of the ideas. I've recently had to do a bit of pandas for a project. Whenever I have to do a new analysis, I try to write it as a single chain of transformations, and then as a more balanced set of updates. ...helps us master concepts Even if the composite parts of a "clever" solution aren't by themselves useful, it still makes us better at the overall language, and that's inherently valuable. A few years ago I wrote Crimes with Python's Pattern Matching. It involves writing horrible code like this: from abc import ABC class NotIterable(ABC): @classmethod def __subclasshook__(cls, C): return not hasattr(C, "__iter__") def f(x): match x: case NotIterable(): print(f"{x} is not iterable") case _: print(f"{x} is iterable") if __name__ == "__main__": f(10) f("string") f([1, 2, 3]) This composes Python match statements, which are broadly useful, and abstract base classes, which are incredibly niche. But even if I never use ABCs in real production code, it helped me understand Python's match semantics and Method Resolution Order better. ...prepares us for necessity Sometimes the clever way is the only way. Maybe we need something faster than the simplest solution. Maybe we are working with constrained tools or frameworks that demand cleverness. Peter Norvig argued that design patterns compensate for missing language features. I'd argue that cleverness is another means of compensating: if our tools don't have an easy way to do something, we need to find a clever way. You see this a lot in formal methods like TLA+. Need to check a hyperproperty? Cast your state space to a directed graph. Need to compose ten specifications together? Combine refinements with state machines. Most difficult problems have a "clever" solution. The real problem is that clever solutions have a skill floor. If normal use of the tool is at difficult 3 out of 10, then basic clever solutions are at 5 out of 10, and it's hard to jump those two steps in the moment you need the cleverness. But if you've practiced with writing overly clever code, you're used to working at a 7 out of 10 level in short bursts, and then you can "drop down" to 5/10. I don't know if that makes too much sense, but I see it happen a lot in practice. ...builds comradery On a few occasions, after getting a pull request merged, I pulled the reviewer over and said "check out this horrible way of doing the same thing". I find that as long as people know they're not going to be subjected to a clever solution in production, they enjoy seeing it! Next week's newsletter will probably also be late, after that we should be back to a regular schedule for the rest of the summer. Mostly grad students outside of CS who have to write scripts to do research. And in more than one data scientist. I think it's correlated with using Jupyter. ↩ If I don't put this at the beginning, I'll get a bajillion responses like "your team will hate you" ↩
Whether we like it or not, email is widely used to identify a person. Code sent to email is used as authentication and sometimes as authorisation for certain actions. I’m not comfortable with Google having such power over me, especially given the fact that they practically don’t have any support you can appeal to. If your Google account is blocked, that’s it. Maybe you know someone from Google and they can help you, but for most of us mortals that’s not an option.
