Official documentation of applications or commands is always the best way to learn about them if you want to know every detail, which a blog or article can’t provide.

And in the Linux community, we can’t deny Arch Wiki is truly a go-to place for anything you want to learn about Linux. Besides Arch, there are other documentations as well which you may also want to prefer like Gentoo or FreeBSD.

So, whether you want to know about a command or jargon in Linux, you can refer to any of the Wiki sites available. But if you’re looking for something that can provide documentation not only of Arch Linux but also of Gentoo, FreeBSD, and others to read in an offline mode, meet Wikiman.

Peppermint is one of those delightful distributions which does what it says it will do. It sets out to be lightweight, easy to set up, and offer native-like access to web applications. It does all of these things and does them well. I also happen to really like the well-organized settings panel and the friendly software manager. I especially like how mintInstall makes it clear when it is working with Deb or Flatpak packages.

While I'm not personally a fan of web applications, I do think Peppermint deserves full credit for making them as easy to use as possible and as native-like as it does. I may never like running my applications over the web, but for people who do like this approach, Peppermint's Ice and SSB features are excellent.

Mostly though I'm a big fan of the distribution's combined LXDE/Xfce desktop. It is a mixture of components which works nicely, is fairly easy to configure, and it offers some of the best performance I have had with an open source desktop this year.

There are some rough edges. The system installer threw out some errors towards the end of the setup process. Needing to logout and back in to see Flatpaks in the application menu was a pain, but not a deal breaker. On the whole I think Peppermint does a good job of feeling modern while offering good performance and easy to use tools.

Two weeks have passed, and the merge window is over. I've tagged and
pushed out 5.10-rc1, and everything looks fairly normal.

This looks to be a bigger release than I expected, and while the merge
window is smaller than the one for 5.8 was, it's not a *lot* smaller.
And 5.8 was our biggest release ever.

I'm not entirely sure whether this is just a general upward trend (we
did seem to plateau for a while there), or just a fluke, or perhaps
due to 5.9 dragging out an extra week. We will see, I guess.

That said, things seem to have gone fairly smoothly. I don't see any
huge red flags, and the merge window didn't cause any unusual issues
for me. Famous last words..

The most interesting - to me - change here is Christoph's setf_fs()
removal (it got merged through Al Viro, as you can see in my mergelog
below).  It's not a _huge_ change, but it's interesting because the
whole model of set_fs() to specify whether a userspace copy actually
goes to user space or kernel space goes back to pretty much the
original release of Linux, and while the name is entirely historic (it
hasn't used the %fs segment register in a long time), the concept has
remained. Until now.

We still do have "set_fs()" around, and not every architecture has
been converted to the new world order, but x86, powerpc, s390 and
RISC-V have had the address space overrides removed, and all the core
work is done. Other architectures will hopefully get converted away
from that very historic model too, but it might take a while to get
rid of it all.

Anyway, to most people that all shouldn't matter at all, and it's
mainly a small historical footnote that 5.10 no longer relies on the
whole set_fs() model. Most of the actual changes are - as usual -
driver updates, but there are changes all over. I think the merge log
below gives some kind of flavor of what's been going on on a high
level, but if you're interested in the details go look at the git
tree. As mentioned, it's a big merge window, with  almost 14k commits
(*) by closer to 1700 people.

Please go test,

                  Linus

(*) closer to 15k commits if you count merges.

• Mike Hoye: Navigational Instruments

  A decade ago I got to sit in on a talk by one of the designers of Microsoft Office who’d worked on the transition to the new Ribbon user interface. There was a lot to learn there, but the most interesting thing was when he explained the core rationale for the redesign: of the top ten new feature requests for Office, every year, six to eight of them were already features built into the product, and had been for at least one previous version. They’d already built all this stuff people kept saying they wanted, and nobody could find it to use it.

  It comes up periodically at my job that we have the same problem; there are so many useful features in Firefox that approximately nobody knows about, even people who’ve been using the browser every day and soaking in the codebase for years. People who work here still find themselves saying “wait, you can do that?” when a colleague shows them some novel feature or way to get around the browser that hasn’t seen a lot of daylight.

  In the hopes of putting this particular peeve to bed, I did a casual survey the other day of people’s favorite examples of underknown or underappreciated features in the product, and I’ve collected a bunch of them here. These aren’t Add-ons, as great as they are; this is what you get from Firefox out of the proverbial box. I’m going to say “Alt” and “Ctrl” a lot here, because I live in PC land, but if you’re on a Mac those are “Option” and “Command” respectively.

  Starting at the top, one of the biggest differences between Firefox and basically everything else out there is right there at the top of the window, the address bar that we call the Quantumbar.

• Cutelyst 2.13 and ASql 0.19 released – Dantti's Blog

  Cutelyst the C++/Qt Web Framework and ASql the ASync SQL library for Qt applications got new versions.

  Thanks to the work on ASql Cutelyst got some significant performance improvements on async requests, as well as a new class called ASync, which automatically detaches the current request from the processing chain, and attaches later on when it goes out of scope.

  With the ASync class you capture it on your ASql lambda and once the query result arrives and the lambda is freed and the ASync object gets out of scope and continues the processing action chain.

• LLVM Lands Very Basic Support For AMD Zen 3 CPUs

  While AMD has landed Znver3 support in GNU Binutils, the company hasn't yet sent out patches for either the GCC or LLVM/Clang compilers in setting up the Zen 3 target with its new instructions or optimized scheduling model / cost table. But a basic implementation has been merged to LLVM for allowing "-march=znver3" based on the limited public details thus far.

  Merged to mainline LLVM 12 yesterday was a basic implementation allowing for -march=znver3 targeting that basically flips on the new instructions known to be supported by Zen 3. Beyond Zen 2, it flips on INVPCID, PKU, VAES, and VPCLMULQDQ. There are also a few other instructions supported by Zen 3 as outlined in this earlier article.

• Warning about Python3 update in latest -current | Alien Pastures

  Warning for people running Slackware-current and have 3rd party packages installed (who doesn’t) that depend on Python3. That includes you who are running KDE Plasma5!

  The “Sun Oct 25 18:05:51 UTC 2020” update in Slackware-current comes with a bump in the Python3 version (to 3.9) which is incompatible with software which already has been compiled against an older version of Python3 (like 3.8).

  I found 26 of my own packages on my laptop that depend on Python3 and they are all probably going to break when upgrading to the latest slackware-current. This includes Plasma5 ‘ktown’ packages but also several of my DAW packages.

Our new and shiny Android port for ScummVM v2.2.1 is now live on the Google Play Store. After quite a long period of dedicated work from our team developers, and a month of public beta testing by members of our community who helpfully reported quite a few issues for us to address, we are finally ready to give you the stable release for our ScummVM Android app.

This app has been significantly re-written and tested on modern Android devices, running up to Android 10+. It includes new features which bring it up to speed with the desktop ScummVM application, such as FluidSynth support, Cloud Saves and more localization choices for the UI. Also included is the Local File Server (LAN) feature, whereby your device can act as a temporary file server allowing you to download files (eg. save files and even the config file) or upload new ones (eg. game data) using a web browser from a PC or another client.

• Linux 5.10 Brings Many Changes From Better CPU Support To File-System Optimizations - Phoronix

  The Linux 5.10 merge window is set to close this afternoon followed by around seven weeks worth of release candidates before the stable kernel release in December. As usual here is our look at the many new features set to premiere with this next version of the Linux kernel.

  With Linux 5.10 there is a lot of work on file-system optimizations and other storage improvements, various additions for AMD Zen 3 processors, continued open-source driver work for Big Navi / Radeon RX 6000 series, mainline support for the Purism Librem 5 smartphone revisions thus far, the Creative SoundBlaster AE-7 support finally being supported under Linux, XFS has shifted its timestamp support from breaking after Year 2038 to now working up to Year 2486, Nintendo Switch controller support, and other new hardware support and other work.

 

• New TTM Code Can Yield 3~5x Faster Page Allocation For AMDGPU, Other Benefits - Phoronix

  The Linux kernel's TTM memory management code that is most notably used by the Radeon / AMDGPU kernel drivers but also Nouveau, QXL, VMWGFX, and others, is seeing a new back-end allocation pool that can yield 3~5x faster page allocation performance for video memory. 

  Longtime AMD Linux driver developer Christian König has been working on this new TT back-end allocation pool that he posted today. With the patch series it is made the default for TTM and updates all existing TTM-based drivers to using this new allocation code for pages. 
    
   

• Alder Lake Support Published For The Open-Source Intel Compute Stack

  This past week Intel began adding Alder Lake support to their Linux graphics driver and that also continued on the compute side with the Intel Compute-Runtime receiving initial support for Alder Lake S "ADLS" too.

  The open-source Intel Compute-Runtime that provides OpenCL and oneAPI Level Zero support for Intel graphics hardware on Linux merged their initial Alder Lake code this week. But given that Alder Lake is still using Gen12-LP graphics like Tiger Lake and Rocket Lake, the enablement isn't too great but just some basic modifications and tweaks while largely leveraging the existing Gen12 paths, just as we've seen with the kernel DRM driver, etc.

  The Alder Lake support for the open-source Intel Compute-Runtime was merged under "opensource ADLS."
