Making Vim Even More Awesome With These Cool Features

Filed under
Linux

​Vim is quite an integral part of Every Linux Distribution and the most useful tool (of course after the terminal) for Linux Users. At least, this theory holds for me. People might argue that for programming, Vim might not be a good choice as there are different IDEs or other sophisticated text editors like Sublime Text 3, Atom etc. which make the programming job pretty easier.

Docker, Inc is Dead

Filed under
Server

To say that Docker had a very rough 2017 is an understatement. Aside from Uber, I can’t think of a more utilized, hyped, and well funded Silicon Valley startup (still in operation) fumbling as bad as Docker did in 2017. People will look back on 2017 as the year Docker, a great piece of software, was completely ruined by bad business practices leading to its end in 2018. This is an outside facing retrospective on how and where Docker went wrong and how Docker’s efforts to fix it are far too little way too late.

[...]

Docker’s doom has been accelerated by the rise of Kubernetes. Docker did itself no favors in its handling of Kubernetes, the open source community’s darling container orchestrator. Docker’s competing product, Docker Swarm, was the only container orchestrator in Docker’s mind. This decision was made despite Kubernetes preferring Docker containers at first. Off the record, Docker Captains confirmed early in 2017 that Kubernetes discussions in articles, at meetups, and at conferences was frowned upon by Docker.

Through dockercon17 in Austin this Kubernetes-less mantra held. Then, rather abruptly, at dockercon EU 17 Docker decided to go all in on Kubernetes. The sudden change was an obvious admission to Kubernetes’ rise and impending dominance. This is only exacerbated by the fact that Docker sponsored and had a booth at KubeCon + CloudNativeCon North America 2017.

[...]

The real problem with Docker is a lack of coherent leadership. There appears to have been a strategic focus around a singular person in the organization. This individual has been pushed further and further away from the core of the company but still remains. The company has reorganized and has shifted its focus to the enterprise. This shift makes sense for Docker’s investors (the company does have a fiduciary responsibility after all). But, this shift is going to reduce the brand’s cool factor that fueled its wild success. It is said that, “Great civilizations are not murdered. They commit suicide.” Docker has done just that.

Programming: LLVM Clang, Debian Tools, OpenCV

Filed under
Development
  • LLVM Clang Gets Support For Configuration Files

    Ahead of next week's LLVM 6.0 feature freeze / code branching, the Clang C/C++ compiler front-end has picked up support for the concept of configuration files.

    Clang configuration files basically come down to a file that can store multiple parameters to pass to Clang, just as you would otherwise do via the command-line but can now be stored into a text file. The purpose of these Clang configuration files is maninly for cross-compiler arguments or other use-cases where you may otherwise be passing a ton of repeated arguments to Clang.

  • pam-krb5 4.8

    This is the default Kerberos PAM module for Debian and Ubuntu systems, and supports both MIT Kerberos and Heimdal. I'm not sure how many people still use straight Kerberos PAM modules these days, with sssd taking off, but I'm still maintaining it.

    This release fixes a somewhat obscure bug: if you configure the module to do expired password changes properly, it checks to see that the expired credentials can still get kadmin/changepw credentials to do the password change. However, it was setting credential options improperly on that call, which could cause it to spuriously fail if, say, krb5.conf is configured to request proxiable credentials but kadmin/changepw doesn't support proxiable credentials. Thanks to Florian Best for the excellent bug report.

  • Animated line drawings with OpenCV

    OpenCV is a pretty versatile C++ computer vision library. Because I use it every day it has also become my go-to tool for creating simple animations at pixel level, for fun, and saving them as video files. This is not one of its core functions but happens to be possible using its GUI drawing tools.

  • rra-c-util 7.0

    This is my collection of utility libraries and support code for (mostly) C software.

    The major version bump is due a backwards-incompatible change: dropping the SA_LEN macro from portable/macros.h, including all the Autoconf machinery to probe for it. This macro came from INN's old portability code when porting to IPv6, but INN turned out to not really need it and it's never caught on. It was causing some warnings with GCC 7 that would otherwise have been hard to fix, so it was time for it to go.

  • C TAP Harness 4.2

    The functional change in this release of my test framework for C programs is the addition of a new is_blob test function. This is equivalent to ok(memcmp(...)) but it reports where the two memory regions differ as a diagnostic.

GNOME: Glade 3.21.0 and GNOME.Asia

  • GNOME.Asia and Engagmeent update

    GNOME.Asia was an amazing event and I wanted to reach out to the organizers and thank them for the wonderful reception that I received while I was there. The trip to Chongqing was mostly uneventful other than the fact every Chinese official was gunning for my battery brick when going through airport security. After a long layover in Beijing, I was landed in Chongqing and met up with Mathias Clasen and proceeded to head to the hotel.

Android Apps on Chrome OS, postmarketOS Coming Along

  • Chromebooks Will Soon Support Parallel Android Apps with the Chrome OS 64 Update

    Google is reportedly bringing support for running multiple Android apps simultaneously on supported Chromebook models via an upcoming update of their Chrome OS Linux-based operating system.

    According to the ChromeUnboxed website, it would appear that the upcoming Chrome OS 64 operating system carries a new feature called "Android Parallel Tasks," which looks to let users run Android apps in the background on Chromebooks that support Google Play Store and Android apps.

    At the moment, Chrome OS pauses Android apps when the focus is no longer on them, which means that it's not possible to run multiple Android apps at the same time. The latest stable release of Chrome OS is version 63 and was released on December 15, a day after Google promoted Chrome OS 64 to the Beta channel.

  • 219 days of postmarketOS

    Most people around us have accepted that it is necessary to buy a new phone every other year. As a smartphone progresses through its own life cycle, manufacturer support for new features become rare, eventually stopping, and the device gets slower and slower. Even worse, after this period, the devices don't get security updates anymore. This means that in many cases the bored IT student next door is able to look up on the Internet how to turn your phone into a surveillance device. Unfortunately the only way to continue to receive security updates after this point is to purchase a new device. In lieu of any alternatives today, you really should purchase a new device to stay current with security updates.

    We want to have another option: postmarketOS is a Linux distribution based on (lightning fast) Alpine that aims for a ten year life-cycle. Instead of having binaries and forked source code for every device, we unify them as much as possible. That allows us to provide updates for all devices at once. The project is still in an early stage (no, you still can't make calls with it.) But it would be a mistake to wait for phone call functionality without informing you about all the breakthroughs we have had. Read on for the exciting changes since day one hundred!

  • libinput and tablet pad keys

    Upcoming in libinput 1.15 is a small feature to support Wacom tablets a tiny bit better. If you look at the higher-end devices in Wacom's range, e.g. the Cintiq 27QHD you'll notice that at the top right of the device are three hardware-buttons with icons. Those buttons are intended to open the config panel, the on-screen display or the virtual keyboard. They've been around for a few years and supported in the kernel for a few releases. But in userspace, they events from those keys were ignored, casted out in the wild before eventually running out of electrons and succumbing to misery. Well, that's all changing now with a new interface being added to libinput to forward those events. Step back a second and let's look at the tablet interfaces. We have one for tablet tools (styli) and one for tablet pads. In the latter, we have events for rings, strips and buttons. The latter are simply numerically ordered, so button 1 is simply button 1 with no special meaning. Anything more specific needs to be handled by the compositor/client side which is responsible for assigning e.g. keyboard shortcuts to those buttons.

  • libinput and button scrolling locks

    For a few years now, libinput has provided button scrolling. Holding a designated button down and moving the device up/down or left/right creates the matching scroll events. We enable this behaviour by default on some devices (e.g. trackpoints) but it's available on mice and some other devices. Users can change the button that triggers it, e.g. assign it to the right button. There are of course a couple of special corner cases to make sure you can still click that button normally but as I said, all this has been available for quite some time now.

  • An unexpected character replacement

    A few weeks ago I found a replacement in GBIF that I'd never seen before: M<fc>ller. It was a hexadecimal value for the character "ü" enclosed in angle brackets. That particular hex value for "ü" appears in Windows-1252 and other encodings, but what program did this replacement? And why? Suspecting the worst, I did a search for other angle-bracket-enclosed strings in the dataset. The search turned up a lot of data items which had originally contained a non-breaking space, and which now contained that character's Unicode representation in brackets, for example Laevicardium. Excluding these, the result is shown here:
