LibreOffice 6.4.5 finally for Slackware 14.2

Filed under
LibO
Slack

The Document Foundation recently released version 7.0.0 of their Libre Office suite of applications. The packages for Slackware-current can be found in my repository. But the situation for Slackware 14.2 used to be different – I got stuck after LibreOffice 6.2 because the newer source releases (6.3 and onwards) require versions of system software that our stable Slackware 14.2 platform does not offer.

From time to time during the last year, when there was time and the build box was not compiling packages, I messed around with the libreoffice.SlackBuild script in futile attempts to compile recent versions of LibreOffice on Slackware 14.2. I failed all the time.
Until last week. After I had uploaded the new KDE Plasma5 packages to ‘ktown‘, I had an epiphany and decided to use a new approach. What I did was: question all the historic stuff in the SlackBuild script that got added whenever I needed to work around compilation failures; and accept that the compilation needs newer versions of software than Slackware 14.2 offers. The first statement meant that I disabled patches and variable declarations that messed with compiler and linker; and for the second statement I stuck to a single guideline: the end product, if I were able to compile a package successfully, has to run out of the box on Slackware 14.2 without the need to update any of the core Slackware packages.

Linux
Slack

More than a year later, the Dev team of Porteus Linux has finally announced the second release candidate (RC-2) for its upcoming version 5.0. This means you can now try the new testing version Porteus 5.0-rc2.

For those who don’t know, Porteus is based on one of the oldest Linux distros, Slackware. It was also formerly known as Slax remix when it started as a community remix of Slax OS.

Porteus aims to provide a portable, fast, and light operating system that you can boot directly in less than 15 seconds (in the case of LXDE desktop) from CD, USB flash drive, hard drive, or other bootable storage media.

KDE Plasma 5 August 2020 release for Slackware

Filed under
KDE
Slack

New Plasma5 packages for Slackware-current are ready for download & installation. I skipped July (holiday season) and so here is KDE-5_20.08 aka my August 2020 release. Be sure to read the upgrade instructions very carefully to prevent breakage, because starting with my June batch the goal is to remove Slackware’s ConsoleKit2 and replace it with elogind!.

It would not harm if you (re-)read my previous blog article about Plasma5, “Replacing ConsoleKit2 with elogind – first steps“. It has a lot more detail about the reasons for this move as well as guidance on using the Wayland Window Manager (as a test) instead of regular X.Org. Note that Wayland sessions still need a lot of maturing and X.Org will remain Slackware’s default choice.

[Slackware] Preparing to move to elogind

Filed under
Slack

Slackware community is very active nowadays, and that's for a reason. They are waiting for the big update coming to Slackware, which is the new Plasma 5 and XFCE. It has been requested for so long after -current start moving, but Pat hasn't made the change until 2020 when big basic components such as Qt5 went in and many followed up.

There were some distractions along the way, such as PAM taking some time to test (it was initially planned for a day or two in testing/), but at the end it was a smooth migration. I barely notice any changes since all the changes happening under the hood and it works well both in my MATE and Cinnamon project (basically for Cinnamon since i already have PAM installed, but not as part of the core packages. It just sit there as a requirement for Cinnamon-screensaver).

For next Plasma 5 and XFCE, there are some another changes needed for it to go smoothly and that's UPower and elogind. Slackware 14.2 up to -current is still using the old UPower which is already deprecated for some time, but since it's related to many other libraries/applications, Pat kept them until it's time to move on with the rest of the projects and i believe it's time. Newer UPower is needed by Plasma 5, XFCE, mate-power-manager 1.24 (it's still at 1.22 for now due to this constraints) and better battery support in Cinnamon.

Plasma5 for Slackware: KDE 5_20.05. Also, new Ardour 6.0

Filed under
KDE
Slack

A new batch of Plasma5 packages for Slackware-current is available now. The KDE-5_20.05 release is also the last monthly update you’ll see from me for a while in my ‘ktown‘ repository. I expect Pat to add Plasma5 to Slackware-current, but I am done waiting and have an urgent need to dedicate my spare time to other matters. With PAM finally added to the core distro, there should no longer be a showstopper for getting rid of KDE4 and replacing it with Plasma5.

And remember, these packages will not work on Slackware 14.2. Along with adding the May batch for -current, I have removed the old (KDE 5_17.11) Plasma5 packages that were still in my ‘ktown’ repository for Slackware 14.2. They have been un-maintained for two and a half years, who knows what security issues they cause. If you really want or need Plasma5, migrate to Slackware-current please.

  • Cinnamon 4.6 Early Preview

    Few days ago i saw that Cinnamon 4.6.0 has been released on GitHub and as usual, developers will still release a couple more releases before they mark it stable, but i have made some changes to the SlackBuild scripts and push it to master branch for those who are eager to try the new Cinnamon 4.6.x series.

    I believe this version will be used in the next Linux Mint 20 which will be released in June, but i want Slackware-Current users to try this version first Smile

  • Use Speedtest CLI to test your Internet Speed on Debian 10

    In order to fix problems with slow connections that lead to poor Internet access, we first want to check the Internet speed on our system. E.g. when you have switched to a new internet connection and want to make sure that you are getting what the provider offers, it is useful to check the internet speed. In this article, we will use a Linux command-line tool called speedtest-cli. It is written in Python and uses the website speedtest.net to check bandwidth by uploading and downloading data to and from your system.

  • Community Account Migration

    The authentication system behind the following services are expect to changed this month. Here is a list of services the might be affected. An email about this topic was sent out on the openSUSE Project Mailing List. More information about this topic will be updated on the Account Migration Wiki page.

    The services using the Community Accounts will migrate step-by-step. This means that for some days you need to use the old and new credentials until the services are migrated.

  • openSUSE Tumbleweed – Review of the week 2020/19

    During this week, we managed to set a new record: the most broken Tumbleweed snapshot handed over to openQA. W whopping 9 tests out of > 220 passed, everything else failed. What a luck we have openQA, right? Nothing of that was mirrored out and sent out to users. Fur the curious ones: the issue came from an incomplete rebuild after the switch to Ruby 2.7. Still, we managed to release 6 snapshots during this week (0429, 0501, 0502, 0503, 0504 and 0506)

  • Old box, dumb code, few thousand connections, no big deal

    I wrote up a load testing tool, too. It will create any number of worker threads, each of which opens a TCP connection back to the server. Each one of those will fire a request down the pipe, wait for the response, sleep a configurable period, and then go again.

    Let's say I stand up the server and a loadgen instance on the same machine. In this case it's my nine-year-old workstation box running Slackware64. I tell the load generator to hit the server (on localhost), run 2000 workers, and wait 200 milliseconds between queries.

    Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Chrome OS, Linux, macOS, and Windows. Learn more about the features listed here through the provided links or from the list on ChromeStatus.com. Chrome 83 is beta as of April 16, 2020.

  • Chrome 83 Beta Rolls Out With Better Form Controls, Barcode Detection API

    Following the release of Chrome 81 earlier this month, Chrome 83 is now in beta with Google having skipped Chrome 82 due to delays / internal issues.

    Chrome 83 Beta is out today with trusted types for DOM manipulation, improved form controls that provide much nicer looking HTML input form controls by default, new origin trials, a barcode detection API is introduced as part of their shape detection API, various WebRTC improvements, and other changes.

  • Chromium 81 – and the new build process for Slackware 14.2

    Google released version 81 of their Chromium browser sources last week, after spending a lot of effort to bring security patches to the 80.x releases in the weeks before. As said before, Google is going to skip the 82 release entirely because of the staffing challenges resulting from the Corina crisis, and will jump straight to release 83 somewhere mid-May.
    I uploaded packages for chromium 81.0.4044.92 a few days ago – but those were only for Slackware-current.

    I found it impossible to compile the latest Chromium 81 code on Slackware 14.2 and I had been trying for days. Yesterday I finally succeeded after more than a week of trying since the sources were released. I can not sit behind my computer for long, but that was not too much of a setback in this particular case. I kept running into new compiler or linker errors, then I would think of a fix, set the box to compile again and had to wait for hours to see the result… and lie down in the meantime. For an entire week, I met failure upon failure.

New ISOs for Slackware Live (liveslak 1.3.5)

Filed under
Slack

I have uploaded a set of fresh Slackware Live Edition ISO images. They are based on the liveslak scripts version 1.3.5. The ISOs are variants of Slackware-current “Tue Feb 18 05:20:50 UTC 2020” with the 5.4.20 kernel but without PAM.
The PLASMA5 variant is my february release of ‘ktown‘ aka KDE-5_20.02 .

Download these ISO files preferably via rsync://slackware.nl/mirrors/slackware-live/ (or its mirror rsync://slackware.uk/people/alien-slacklive/ but allow that 24 to sync up) because that allows easy resume if you cannot download the file in one go.

Programming Leftovers

  • Ned Batchelder: Scriv

    I’ve written a tool for managing changelog files, called scriv. It focuses on a simple workflow, but with lots of flexibility. I’ve long felt that it’s enormously beneficial for engineers to write about what they do, not only so that other people can understand it, but to help the engineers themselves understand it. Writing about a thing gives you another perspective on it, your own code included.

  • [Perl] Week #078: Leader Element & Left Rotation

    First thing first, I managed to do video session for both tasks this week. It is so satisfying when everything goes as per the plan. For the last couple of weeks, I could only do one video session. One day, I would like to video with PIP. At the moment, I am little uncomfortable showing my face in the video. There is another reason why I can’t do it now. I don’t have my personal office in the house. I have been working from home since mid-March, nearly 6 months, sitting on sofa, 9-5. I must confess it is not easy. I miss my office chair and noise-free environment. I have 3 years twin girls. Luckily the school started last week, I get no-noise moment for few hours during the day. Also this week, I found time to do coding in Swift.

  • Searching Greek and Hebrew with regular expressions

    According to the Python Cookbook, “Mixing Unicode and regular expressions is often a good way to make your head explode.” It is thus with fear and trembling that I dip my toe into using Unicode with Greek and Hebrew. I heard recently that there are anomalies in the Hebrew Bible where the final form of a letter is deliberately used in the middle of a word. That made me think about searching for such anomalies with regular expressions. I’ll come back to that shortly, but I’ll start by looking at Greek where things are a little simpler.

Best Free and Open Source Terminal Session Recording

The vast majority of computer users depend on a graphical user interface, and fear the command line. However, the command line holds significant power and versatility. Commands issued from a shell offer system administrators a quick and easy way to update, configure and repair a system. The benefits of the command line are not only confined to system administration. The ability to transverse the file system quickly, give more information about files and directories, automate tasks, bring together the power of multiple console tools in a single command line, and run shell scripts are just a few examples of how the command line can offer a potent, multifarious toolbox.

Keep Tabs on Your To-Do Lists With This GNOME Extension

Task Widget is an open source GNOME extension that shows your to-do list embedded in the GNOME message tray (also known as the calendar or notification shade). This widget area displays your pending to-do items, and lets you check off tasks as you complete them. Task Widget is is able to integrate “…with GNOME Online Accounts and a number of GNOME applications, such as Evolution and To Do” but it is is not, by design, intended to replace any of those apps or services. Or to put it another way: it’s not a standalone task manager or to-do app. You can’t, for example, add a task from the widget area, or edit one either. You can only mark a task as done (or unmark it as done). Read more
