Dear Tumbleweed users and hackers,

This week might not have seen the highest count of snapshots being published (only 3, 0212, 0215, and 0217), but for sure we reached the highest count of packages to replace on your system and megabytes to transfer this year (so far). We have few reasons to trigger rebuilds of all packages, and most of the time I do that on a glibc update and when we switch the default compiler (in both cases to make use of new technologies). This week, glibc was the ‘guilty’ one.

The three snapshots contained the following changes (and more):

• glibc 2.33
• Mozilla Thunderbird 78.7.1
• Mozilla Firefox 85.0.1
• Linux kernel 5.10.14 & 5.10.16
• LibreOffice 7.1.0.3
• KDE Plasma 5.21.0
• KDE Frameworks 5.79.0
• postfix 3.5.9: note: the default format for its databases changed from bdb to lmdb; bdb support is in postfix-bdb

That is almost everything I promised you last week. Almost! But don’t worry: while we all enjoy a stable, rolling release, the developers keep on submitting new changes. Currently, we are testing the integration of these parts:

• Linux kernel 5.11.x
• Binutils 2.36
• GNOME 3.38.4 (GNOME 40.beta is being tested in GNOME:Next)
• openssl 1.1.1i, based on centralized crypto-policies package
• Use GCC 11 as default compiler (Staging:Gcc7)

Since there is a part of me still stuck in 1998, I do enjoy using my Texas Instruments TI-86 calculator for math things. When I have a complex equation that my middle-aged brain just can’t seem to work out, I reach for my trusty old TI-86. It has been a faithful companion that has been … Continue reading Linking a TI-86 Calculator with openSUSE →

No hay manera de aligerar mi lista de audios pendientes de mi reproductor de podcast. A los ya clásicos (que aparecerán abajo) se ha añadido la lista de 24 episodios de 24H24L… y el nuevo programa que viene de ultramar llamado Podcast de Ubuntu Colombia y que vale la pena escuchar por varias razones, siendo una de ellas poder escuchar a Lina Castro, linuxera que conocí en un programa de Radio Bétera.

Podcast de Ubuntu Colombia, más audios linuxeros

El lista de podcast dedicados al mundo GNU/Linux sigue creciendo :Podcast Linux, Compilando Linux, Salmorejo Geek, SystemInside Podcast, Birras y Bits, los de KDE España, los de GNU/Linux Valencia, el de NeoSiteLinux o el de Mancomún Podcast, que comenté hace ya un tiempo. Estoy seguro que me dejo alguno, así que pido disculpas por anticipado y os pido que me pongáis en los comentarios el enlace a él).

Pero parece que siempre encuentro de nuevos a poco que busque un poco por la red o me comenten por las redes sociales. En esta ocasión me complace compartir con vosotros la existencia de los Podcast de Ubuntu Colombia.

Estos programas tienen una duración muy variable, que van desde los 7 minutos a casi la hora de duración, con lo que se adaptan bien a cualquier ratito que tengas libre.

Su temática es variada y nos encontramos con noticias, proyectos, pequeños monográficos, eventos y una buena cantidad de información, incluso de temas privativos.

Como es habitual, os dejo abajo una muestra del trabajo de los chicos de Podcast de Ubuntu Colombia con su segundo programa titulado «Cómo Ubuntu cambió mi vida », primer podcast con Lina Castro, impulsora de la iniciativa #viernesdeescritorio y que seguro que os encantará.

La criptomonedas o monedas virtuales han llegado para quedarse. Al menos por ahora ya que, en mi opinión, pueden tener en su contra los grandes intereses comerciales que pueden llevar al traste tu futuro. La Comunidad del Software Libre no es ajeno a este movimiento y ha creado sus propios plasmoides como Bitcoin Price, que presenté hace un tiempo, o Crypto Currency Price, que también tuvo su entrada en el blog. Hoy me alegra compartir con todos vosotros otra como alternativa Crypto Tracker con el que llegamos a los 171 plasmoides presentados en el blog.

Crypto Tracker – Plasmoides de KDE (171)

Podemos consultar en la Wikipedia  que «Una criptomoneda o criptodivisa es un medio digital de intercambio». En otras palabras, una alternativa para adquirir bienes y servicios basado en transacciones virtuales y alejado de los métodos tradicionales.

Bitcoin fue la primera moneda virtual que apareció, en el lejano 2009 y desde luego no han tardado en aparecer alternativas como Litecoin, Ripple, Dogecoin o Ethereum.No obstante sigue siendo Bitcoin más famosa..

Así que, en la actualidad, mucha gente está empezando a utilizar Bitcoin como una moneda más para comprar o vender productos así que no estaría de más tener un plasmoide que me permita visualizar su valor en diferentes mercados.

Justamente eso hace Crypto Tracker un plasmoide que es capaz de visualizar estos el valor respecto al dolar de un varias monedas virtuales.

Esta es su primera versión, así que si véis alguna cosa rara no dudéis en decírselo a su creador marcinorlowski.

Y como siempre digo, si os gusta el plasmoide podéis “pagarlo” de muchas formas en la nueva página de KDE Store, que estoy seguro que el desarrollador lo agradecerá: puntúale positivamente, hazle un comentario en la página o realiza una donación. Ayudar al desarrollo del Software Libre también se hace simplemente dando las gracias, ayuda mucho más de lo que os podéis imaginar, recordad la campaña I love Free Software Day 2017 de la Free Software Foundation donde se nos recordaba esta forma tan sencilla de colaborar con el gran proyecto del Software Libre y que en el blog dedicamos un artículo.

¿Qué son los plasmoides?

Para los no iniciados en el blog, quizás la palabra plasmoide le suene un poco rara pero no es mas que el nombre que reciben los widgets para el escritorio Plasma de KDE.

En otras palabras, los plasmoides no son más que pequeñas aplicaciones que puestas sobre el escritorio o sobre una de las barras de tareas del mismo aumentan las funcionalidades del mismo o simplemente lo decoran.

Today we reached a new milestone: all openSUSE services around the world now support IPv6 natively. The last set of machines in Provo are equipped with IPv6 addresses since today. IPv6 was missing for those machines since the renumbering (which was needed because of the carve out of SUSE from Microfocus). Thanks to one of our providers, who now reserved and routed a whole /48-IPv6 network for us.

With this, we can also run all our DNS servers with IPv6 (and they do not only have a IPv6 address, but all our external DNS entries for the opensuse.org domain should now contain IPv4 and IPv6 addresses as well. Don't worry, you did not miss much. The Dual-Stack (IPv4 and IPv6) is the case for all services in Germany since a long, long time already - and we even had it for the machines in US for a long time, before SUSE switched the provider. But this finally brings us to the same level on all locations!

I was going down a retro computing rabbit hole and I stumbled upon this fantastic little device that allows you to plug in more modern game pads into the Commodore 64. Specifically, NES, SNES and Sega Genesis, the 64JPX. This is a small interface that plugs into the DB9 ports of the Commodore, Atari and … Continue reading 64JPX | JoyPad eXpander for the Commodore 64 →

Updates of both KDE’s Plasma and Frameworks landed in openSUSE Tumbleweed as part of three snapshots released this week.

The rolling Tumbleweed distribution began the week with Linux Kernel 5.10.12 and has ended it with version 5.10.16, which was the latest stable Kernel when the 20210215 snapshot was released.

The newest Frameworks 5.79.0 version arrived in snapshot 20210217. As part of the release, Kholidays package updated holidays for Mauritius and Taiwan. The Kirigami user interface framework had fixes to the controls and enhanced some vertical alignments. Removal of the usage of non-UTF-8 string literals were made with Framework’s kcodecs package update. GNOME had some updates with gnome-builder updating to version 3.38.2, which provided support for an --add-policy for Flatpak, and gnome-software updating to version 3.38.1, which updated translations and ignores harmless warnings when using unusual fwupd versions. Three areas of focus were emphasized for the update of dhcp 4.4.2 with changes for dynamic DNS additions, dhclient improvements and support for dynamic shared libraries; the package is now licensed under the Mozilla Public License, MPL 2.0. Multiple PyPI packages were updated including python-greenlet 1.0.0, which requires setuptools to build from source, and python-numpy 1.20.1, which fixed a random.shuffle regression. A major update of perl-Mojolicious 9.01 added an experimental color attribute and an experimental color log environment variable. Other packages to update in the snapshot were Long-Term Support package subversion 1.14.1, filesystem mounter fuse3 3.10.2, pipewire 0.3.21 and git 2.30.1.

Plasma 5.21 is all about upgrading the looks and usability of Plasma. Snapshot 20210215 brought this Plasma update, which refreshed the color scheme and sports a brand new unified headerbar style with a clean and cool new look. The new Plasma System Monitor app for monitoring system resources is now an integral part of Plasma; the application shows all the running applications along with detailed statistics and graphs. Plasma 5.21 makes massive progress toward first-class support for Wayland. The virtual keyboard in Wayland has been improved and supports GTK applications using the text-input-v3 protocol. The update of Mozilla Firefox 85.0.1 fixed a few bugs like a crash in the browser in case of an unexpected Cache Application Programming Interface state. The trim that was not working in ImageMagick was fixed in version 7.0.10.62 and the GPS info for TIFF images now works with the imaging applications. Terminal emulator xterm 366 corrected the upper-limit for a selection buffer, which fixed a Common Vulnerabilities and Exposure. PDF library poppler 21.02.0 fixed a memory leak if saving a file fails. Some other packages in the snapshot were LibreSSL 3.2.4, text rendering package pango 1.48.2 and Linux Kernel 5.10.16.

The Linux Kernel updated from 5.10.12 to 5.10.14 in the 20210212 snapshot, which brought in some KVM fixes. New packages were inherited from GNU Compiler Collection 10 into the GCC 11.0.0+git183291 update. CardDAV address books now support OAuth2 and Google Contacts in the email client update of Mozilla Thunderbird 78.7.1. The glibc 2.33 version optimized dynamic linker loads and the implementations of shared objects from subdirectories under the glibc-hwcaps directory on the library search path; that’s if the system’s capabilities meet the requirements for this subdirectory. The 7.1.0.3 LibreOffice updated bundled dependencies and php7 7.4.15 fixed a Curl bug and core fix that provided a bogus parser error on more than 4GB of source code. The regular expression library re2 had an update from a November release to version 20210202, which addressed -Wnull-dereference warnings from GCC 10.x.

Things are hectic and busy here on Earth. We may have disrupted the seeemingly eternal atmospheric streams by warming up the planet. We seem to be really terrible at dealing with a viral threat we've known about for a long time. We're doing a lot of bad things as species.

But today I won't be bitching about our government failing to distribute vaccines handed to them on a silver platter. I'll be admiring the work of another government agency that did amazingly organizing resources and talent and will be landing the Perseverance rover on Mars at 19:15 UTC.

Today we reached a new milestone: all openSUSE services around the world now support IPv6 natively. The last set of machines in Provo are equipped with IPv6 addresses since today. IPv6 was missing for those machines since the renumbering, which was needed because of the carve out of SUSE from Micro Focus. A big thank you goes out to one of our providers, who now reserved and routed a whole /50-IPv6 network for us.

With this, we can also run all our DNS servers with IPv6 (and they do not only have an IPv6 address, but all our external DNS entries for the opensuse.org domain should now contain IPv4 and IPv6 addresses as well. Don’t worry, you did not miss much. The Dual-Stack (IPv4 and IPv6) is the case for all services in Germany since a long, long time already - and we even had it for the machines in the US for a long time, before SUSE switched the provider.
