Mi escritorio Plasma de diciembre 2021 #viernesdeescritorio

Finalizo este año de la iniciativa #viernesdeescritorio con una nueva captura y superando más de un año entero seguido y sin faltas de entradas en la serie «Mi escritorio». De esta forma, bienvenidos a mi escritorio Plasma de diciembre 2021 que sigue en el tema oscuro del mes pasado y mostrando cambios radicales.

Mi escritorio Plasma de diciembre 2021 #viernesdeescritorio

Esta va a ser la decimocatva vez que muestro mi escritorio Plasma 5 en público, lo cual es número nada desdeñable de entradas. La entrada recopilatoria de las misma está cada vez más cerca… siempre lo digo pero nunca llega.

Además, he recuperando un plasmoide informativo de tiempo y meteorología animado y muy completo que no solo me ofrece información sino que me muestra incluso las fases de la luna. Ya hablaré de él más adelante que se merece una entrada en la sección de plasmoides.

Respecto al mes pasado ha cambiado bastante ya que aunque sigo utilizando el tema global Brisa oscuro, he cambiado el estilo de plasma, el fondo de pantalla a uno azul eléctrico . Además he añadido 2 barras de tareas y un par de plasmoides.

Respecto al estilo plasma se trata de Kadiya, que me proporciona unos bordes redondeados que me encantan y una transparencia ajustable.

Por otra parte, la barra de la izquierda es simplemente la básica de Plasma pero redimensionada, reorganizados los plasmoides y sin el gestor de tareas, ya que esa funcionalidad me sigue gustando en la parte inferior.

Y justo en esta segunda barra donde hay más novedad ya que tras probar Plank hace unas semanas he decidido utilizarla de forma diaria. Si queréis saber más leed esta entrada.

Para finalizar, los plasmoides empleados son: Digital Clock Be Style, con ligeras modificaciones en el color de las agujas; y Condensed Weather para el informe meterológico.

De nuevo he realizado la descripción de las características de mi equipo de con neofetch. aunque esta vez ejecutado desde un Yakuake modificado para estar a la izquierda y redimensidado para que sea menos ancho.

Como es habitual, la captura está realizada sobre mi portátil Slimbook Pro de 13 pulgadas, el cual tiene instalado un KDE Neon con Plasma 5.23.4 (el último hasta el momento).

El resultado de mi escritorio de diciembre de 2021 es un escritorio oscuro pero luminoso, limpio y funcional que podéis ver en la imagen inferior (pinchad sobre ella para verlo un poco más grande)

Frameworks, Gear, Pipewire Update in Tumbleweed

There was no slowing down of snapshots this week as new software continues to flow with daily openSUSE Tumbleweed releases. Tumbleweed went seven for seven this week!

Just two updates were in the 20211214 snapshot. The remote accessing package remmina 1.4.22 provided fixes for freerdp3 compatibility, and remmina also had a fix for a crash if the main window is closed. The libcap-ng 0.7.11 package, which analyzes a system for apps with too many privileges, removed unneeded rules.

Among the many packages that arrive in snapshot 20211213 were KDE’s Gear 21.12.0 and Frameworks 5.89.0 versions. Gear 21.12.0 had some Dolphin file manager enhancements like a Ctrl + i filter feature that brings up a box under the main panel, which added a new Detailed View feature through a right click on an empty space; select the View Mode > Details from the pop up menu. The screenshot application Spectacle gives KDE users a cleaner look of images they drag and drop from Spectacle’s preview panel to Dolphin or to an online image storage site for sharing. The Kdenlive video editor from Gear improved the motion tracking tools; Just use the box in the monitor to cover the area to track, click Analyse in the effects panel, and have fun! The video editor also has a new audio effect that removes background noises from recordings; the Noise Suppressor allows for a voice grab in the audio effects tab to be dropped onto an audio track for clean up. Frameworks 5.89.0 had a considerable amount of bug fixes for the Breeze Icons, which included the addition of a missing kmail breeze icon. The KContacts fixed address formatting for country-only addresses and deprecated countryToISO/ISOToCountry in favor of KCountry. Both KIO and Kirigami had some changes; the latter package lets the escape key close and push the dialog layers. The application library exo updated to version 4.16.3 and fixed compilation warnings; the package that is targeted at application development for Xfce also added typecheck verification to prevent a GTK bug warning. The mpg123 1.29.3 package fixed typos and added a note about equalizer frequency bands in the man page. The updated 370 version of xterm improved performance over slow connections and suppressed the loading of italic font in a few places when the colorITmode is enabled. Other packages to update were yast2-bootloader 4.4.10 and yast2-storage-ng 4.4.23, which added support for mount options use with libstorage-ng to determine whether a efibootmgr is available.

The second update of the week for the Advanced Linux Sound Architecture package arrived in snapshot 20211212. The alsa 1.2.6.1 version fixed the configuration for device parsing. Several alsa changes were made in the kernel-source 5.15.7 update. The kernel also had several KVM fixes to include a shadow nested paging that does not have Protection Keys for Userspace. Since there is now a require dependency, wireplumber became the session manager for pipewire 0.3.40 in the snapshot; “when in doubt, the suggested package is selected,” according to the changelog. The python-cryptography package updated from version 3.4.8 to 36.0.0, which went through a version number change in September. The new Python Package Index has the entire X.509 layer written in Rust; this allows alternate asymmetric key implementations that can support cloud key management services or hardware security modules provided they implement the necessary interface. About 10 more updates arrived in the snapshot.

Quite a few GNOME packages received a version bump in snapshot 20211211. While there were translation updates for gnome-maps 41.2, gnome-software 41.2 fixed a crash when processing age ratings and reloaded application details only when the items were not installing/removing the application. The gupnp 1.4.1 package fixed a regression in the async deprecated Application Programming Interfaces. Mozilla Firefox 95.0 updated in the snapshot, and fixed some Common Vulnerabilities and Exposures. The release appears to be a nod at Windows 95 now that the browser is available in the Microsoft Store. A fix in the use of the default log writer with journald namespaces was made in the glib2 2.70.2 update. Other packages to update in the snapshot were hwdata 0.354, FireEye’s hxtools 20211204, LibreOffice 7.2.4.1, Node.js, 16.13.1, vte 0.66.2, yast2-installation 4.4.28 and more.

Three packages were updated in snapshot 20211210. An added method to disconnect proxy signals was made in the gnome-remote-desktop 41.2 update; the package, which can also be used for screencasting, made warning messages a little bit more explicit. The Linux laptop battery Optimizing package tlp 1.4.0 renamed “Battery Features” to “Battery Care” and introduced plugins to support Battery Care for non-ThinkPads; ASUS, Huawei, LG, Lenovo and Samsung are the first to benefit from the plugins. The kernel headers were updated in the linux-glibc-devel 5.15 release.

Most of the updates in snapshot 20211209 were PyPi updates with the exception of the libffi 3.4.2 and nvme-cli 1.16 updates. Snapshot 20211208 provided the first asla 1.2.6 update, which improved the support of multiple formats in the Pulse-code modulation. The sudo 1.9.8p2 package fixed a few minor memory leaks and sudo_logsrvd now only sends a log ID for the first command of a session, so there is no need to send the log ID for each sub-command. Several other packages were updated in the snapshot like screen reader orca 41.1, soundtouch 2.3.1 and yast2-journal 4.4.1, which is preparing code for Ruby3 along with many other YaST packages.

Bloquea un paquete de software en #openSUSE con zypper

Veamos cómo usar zypper, el gestor de paquetes de software de openSUSE, para bloquear un paquete en concreto

openSUSE Tumbleweed, es una distribución de GNU/Linux «rolling release», esto quiere decir que se van actualizando las versiones de software instalado de manera contínua.

Como puedes leer en los resúmenes semanales que publico en el blog, todas las semanas se publican nuevas actualizaciones, ¡algunas semanas casi a diario!

Imaginemos que tenemos un software, por ejemplo el editor nano, que por alguna circunstancia no queremos que se nos actualice a versiones más modernas que la que tenemos funcionando ahora, o que no queremos que alguien lo desinstale, etc.

Veamos cómo podemos bloquear el paquete de software con la herramienta zypper, para que no se puedan realizar estas operaciones.

Para bloquear un paquete con zypper utilizaremos las herramientas locks (ll) addlock (al) removelock (rl) o cleanlocks (cl). Entre paréntesis están los comandos cortos para utilizar con zypper. Veamos unos ejemplos.

Listar paquetes bloqueados

Primero vamos a comprobar si existen bloqueos ya existentes en nuestro sistema, para ello ejecuto zypper locks o ll:

zypper ll
No hay bloqueos de paquete definidos.

Añadir un bloqueo

Ahora, como ejemplo vamos a añadir un bloqueo al software nano. Deberemos hacerlo con privilegios de root:

zypper al nano*                                                                                                                   
El bloqueo se ha añadido correctamente.

Si volvemos a ejecutar un listado de paquetes bloqueados veremos algo distinto:

zypper ll

# | Name   | Type    | Repository   | Comment
--+--------+---------+--------------+-----------
1 | nano*  | package | (cualquiera) | 

Como véis, en vez de bloquear un paquete de software específico, escribiendo su nombre exacto, he bloqueado todos los paquetes de software que empiezan con nano (todos relativos a este editor de texto)

El editor nano quedará «congelado». No se actualizará a nuevas versiones si están disponibles en los repositorios, ni lo podremos eliminar del sistema. Vamos a probar a desinstalarlo con zypper:

zypper rm nano
Leyendo los paquetes instalados...
Resolviendo dependencias de paquete...

Problema: peticiones en conflicto
 Solución 1: Se realizarán las siguientes acciones:
  elimine el bloqueo para permitir la eliminación de nano-5.9-1.1.x86_64
  elimine el bloqueo para permitir la eliminación de nano-lang-5.9-1.1.noarch
 Solución 2: no perdir que se supriman todos los elementos solucionables que proporcionen nano.x86_64 = 5.9-1.1

Elija las soluciones usando '1' o cancele usando 'c' [1/2/c/i/?] (c): c

Ahora imaginemos que también queremos bloquear el paquete de Vim, porque hay una actualización que nos rompería alguna funcionalidad con un complemento que tenemos, o algo así…

zypper al vim                                                                                                                    
El bloqueo se ha añadido correctamente.

En este caso solo hemos bloqueado el paquete llamado literalmente vim, permitiendo que otros que empiezan por vim se actualicen normalmente.

zypper ll

# | Name   | Type    | Repository   | Comment
--+--------+---------+--------------+-----------
1 | nano*  | package | (cualquiera) | 
2 | vim    | package | (cualquiera) | 

Bloquear un paquete de un repositorio específico

También podemos bloquear un paquete de software para que no se actualice desde un repositorio en concreto, permitiendo que si está disponible en otros repositorios se actualice desde allí:

zypper al -r repo-oss virtualbox*

Se bloqueará ese software desde dicho repositorio llamado repo-oss pero se podrá actualizar desde otros. Veamos el listado de bloqueos de nuevo:

zypper ll

# | Name        | Type    | Repository   | Comment
--+-------------+---------+--------------+-----------
1 | nano*       | package | (cualquiera) | 
2 | vim         | package | (cualquiera) | 
3 | virtualbox* | package | repo-oss     | 

Eliminar bloqueos

Ahora vamos a eliminar el bloqueo de vim, ya que ya podemos volver a actualizarlo:

zypper rl vim                                                                                                                     
1 bloqueo se ha eliminado correctamente.

zypper ll

# | Name        | Type    | Repository   | Comment
--+-------------+---------+--------------+-----------
1 | nano*       | package | (cualquiera) | 
2 | virtualbox* | package | repo-oss     | 

También podemos especificar no el nombre del paquete, si no el número dentro de la lista de bloqueos que ocupa. Eliminemos el bloqueo de nano:

zypper rl 1
Se ha eliminado correctamente el bloqueo especificado.
1 bloqueo se ha eliminado correctamente.

Quedando así nuestra lista de bloqueos:

zypper ll

# | Name        | Type    | Repository  | Comment
--+-------------+---------+-------------+-----------
1 | virtualbox* | package | repo-oss    | 

Podremos volver a ejecutar el comando anterior, para ahora eliminar el que ocupa la posición 1. Eliminando todos los bloqueos que había en nuestro sistema.

Bloquear con YaST

Seguro que te lo estás preguntando, sí desde YaST también se puede hacer todo esto. Abrimos YaST y vamos a la sección instalar/desinstalar software.

Escribimos en el cuadro de búsqueda el paquete que queremos, por ejemplo nano otra vez, y con botón derecho seleccionamos la opción Protegido, no modificar.

Si son varios los paquetes que queremos seleccionar, escogeremos la opción Todos los de la lista y seleccionaremos Protegido, no modificar.

Para volverlos a activar, seleccionaríamos la opción Mantener con el botón derecho.

Espero que os haya resultado útil esta opción si no la conocías de openSUSE a la hora de gestionar paquetes de software. ¿Lo vas a poner en práctica ahora que has aprendido este comando? Compártelo en los comentarios.

El escritorio Plasma de KDE en 3 minutos

Aunque tengo temas de que hablar, hoy no tengo el cuerpo para hacerlo. Así que voy al recurso fácil de presentaros un video. Concretamente uno en el que nos muestran el escritorio Plasma de KDE en 3 minutos en forma de vídeo de mano de TechHut. Una pequeño pero gran vídeo que sirve de introducción al increíble entorno de trabajo de la Comunidad KDE.

El escritorio Plasma de KDE en 3 minutos

Quizás un problema de Plasma, el escritorio de KDE, es sus infinitas posibilidades, lo cual hace que no sea sencillo explicarlo sin abrumar.

Mi escritorio Plasma de octubre

Es por ello que me complace compartir con vosotros este vídeo de TechHut donde en apenas tres minutos nos presentan las características más destacadas de este entorno de trabajo.

A continuación os dejo el vídeo, donde no solo habla en esos 300 segundos del entorno básico de Plasma sino que se atreve a comentar también scripts de KWin como Krohnkite.

Por supuesto que esto es una pincelada, los lectores del blog saben que Plasma es esto y mucho más, que KDE es una activa y prolífica Comunidad y que tu, como cualquier simpatizante del Software Libre, puede formar parte de ella si así se lo propone.

Celebrate the first openSUSE BAR anniversary!

Almost a year ago, on the 19th of December 2020, openSUSE Members knurpht and m4u had the following conversation:

Gertjan™ - Knurpht™, [19.12.20 00:05]
Dude, have a drink on meet.opensuse.org/beer?

Gertjan™ - Knurpht™, [19.12.20 01:11]
Yo, we( Neal and me are waiting for you to show up

Maurizio G., [19.12.20 05:36]
let’s see how i feel after coffee

Maurizio G., [19.12.20 05:38]
are you and neal still in the BAR?

Gertjan™ - Knurpht™, [19.12.20 05:39]
Nope
We were in the beer btw 😃

Maurizio G., [19.12.20 05:41]
yea i saw your message

Maurizio G., [19.12.20 05:41]
i’m just waking up. maybe in a bit

Gertjan™ - Knurpht™, [19.12.20 05:42]
Now in meet.opensuse.org/BAR

This was the birth of our beloved openSUSE BAR! Since then, the BAR has been a place for contributions, for fixing things together and just hanging out.

The BAR evolved into an important part of our community that helps people get to know each other in the project. It has on-boarded new contributors, strengthened old friendships, brought fixes for various issues on the way and was the place for historical events, such as probably the oldest openSUSE User (89 y.o.) meeting the youngest openSUSE Member (16 y.o.).

During the online openSUSE Leap 15.3 release party, which was aimed to last for 24 hours, the bar passed the marks of a 50+ guests and a 100-hour-BAR session on June 6, 2021, which was followed by reaching a mark of a 200-hour-BAR session on June 10, 2021.

To celebrate the first-year anniversary of the BAR, the second largest BAR event is going to begin on Dec. 18 starting 16:00 UTC at meet.opensuse.org/bar!! Let’s see how long we can keep the party going this time!

We definitely look forward to seeing you all there!! New faces, old friends, those that visit the BAR regularly, and those who have never logged on before. Cheers!

NOTE: Please don’t be discouraged if it takes you a couple of tries to connect! Just keep trying!! Just keep trying and mash the F5 key to refresh, you won’t regret it!!

Novedades de Spectacle de KDE Gear 21.12

El pasado jueves 9 de diciembre fueron lanzadas las mejoras en las aplicaciones de la KDE Gear 21.12. Es hora de ir revisando aplicación a aplicación qué nos podemos encontrar. El primero de la lista fue Dolphin, hoy es el turno de las novedades de Spectacle de KDE Gear 21.12, el capturador de pantalla que susutituyó a KSnapshot y que gana funcionalidades versión a versión.

Novedades de Spectacle de KDE Gear 21.12

Novedades de Spectacle de KDE Gear 21.12

Para quienes no lo sepan, al extinto KSnaphot le sustituyó Spectacle, la aplicación de captura de pantalla de KDE que va sumando funcionalidades que ya lo hacen estar a la altura de su antecesor. De hecho, en mi última charla de Akademy-es 2021 le dediqué su merecido tiempo

Creo que es interesante recordar que Spectacle puede capturar el escritorio completo, el monitor que deseemos, la ventana activa o una región determinada del mismo. Todo ello con opciones de temporización, atajos de teclado o posibilidad de compartir con otras aplicaciones, y en sus últimas versiones incorpora un completo editor de imágenes integrado para crear capturas completas.

Veamos las novedades de Spectacle de KDE Gear 21.12

  • Mejoras al inicio de la aplicación: ahora puede hacer que realice una captura automática de toda la pantalla, hacer que recuerde exactamente todos los parámetros de la última captura que hizo antes de cerrarlo (por ejemplo, resaltar exactamente la misma región del escritorio de la última captura rectangular) para volver a realizar una captura, o configurarlo para que no haga ninguna captura.
  • Mejorado el aspecto de las imágenes mientras las arrastra desde el panel de vista previa de Spectacle y las suelta en Dolphin para guardarlas o en un sitio de almacenamiento de imágenes en línea para compartirlas (sí, también puede hacer esto).
  • Posibilidad de realizar capturas correctamente coloreadas en pantallas que permiten usar color de 10 bits por canal.
  • Mejoras en Wayland, ahora Spectacle puede capturar la «Ventana activa».

Fedora, CentOS and me

Let me share my Fedora story with you. Hopefully, it helps you to understand, why I am also promoting AlmaLinux and Rocky Linux, even if I am an active Fedora and CentOS community member and contributor.

Before the beginnings

Someone suggested me to try Red Hat Linux in 1995 and replace Slackware Linux with it on my university server. I installed it, but I did not become a fan. And when I found the print out of the password file of my server on the wall of the Russian students' computer lab (see: https://peter.czanik.hu/posts/russian_students_logging/), I quickly switched to Jurix, which already featured shadow passwords. And as Jurix became the base for SUSE Linux, I became a SUSE Linux and later an openSUSE user.

The beginnings

When I started to work at Balabit (now part of One Identity) almost twelve years ago, one of my first tasks was to ensure that the latest version of syslog-ng is available in Linux distributions and FreeBSD. I reached out to package maintainers and helped them to update the syslog-ng package. It went quite well in most cases, but I was stuck with Fedora and EPEL updates. I tried to reach out to developers through official and unofficial channels without luck.

syslog-ng logo

While talking to syslog-ng users, I tried to figure out what OS they use. It turned out that even if syslog-ng was the default syslog implementation in openSUSE and SLES, our most active users were running syslog-ng on RHEL and CentOS. So, I became even more active trying to resolve the syslog-ng package situation, still without luck.

The turn of events arrived almost a year later at FOSDEM. What could not be solved with tickets and e-mails was resolved within five minutes at the Fedora booth in person at FOSDEM. I met a Hungarian Fedora ambassador there who connected me with the right people, and syslog-ng was soon updated to the latest version.

Friends

Freedom, friends, features, first, are the four core values of Fedora. From those “Friends” became very important to me. Even if my operating systems of choice are openSUSE (https://peter.czanik.hu/posts/opensuse_memories_1/) and FreeBSD, I do not have many friends in those communities. However, soon after that initial meeting at the Fedora booth at FOSDEM I got many friends in the Fedora community, both here in Hungary and abroad. I helped in organizing some local gatherings and soon I was asked to become a Fedora ambassador. I gave Fedora talks at various events and helped maintaining the Fedora booth around Europe.

syslog-ng packaging

At first I helped syslog-ng package maintainers with upstream information. Soon I was asked to become a co-maintainer for the syslog-ng package in Fedora and EPEL. I did minor version updates, new syslog-ng features, while the original maintainers did larger changes, like enabling systemd support, new EPEL versions, and so on.

For the past couple of years I maintain syslog-ng mostly alone, both in Fedora and EPEL. I also have my unofficial packages in Copr. This is necessary, as the EPEL policy does not allow version upgrades, while users want to use the latest syslog-ng features.

CentOS Stream and the new RHEL clones

When the end of the traditional CentOS Linux was announced, many syslog-ng users cried out loud. Based on my estimates, about 80% of syslog-ng users run CentOS or RHEL, so I’m monitoring the situation as much as I can. I had a couple of Twitter polls, e-mails on the syslog-ng mailing list and direct discussions with some of our power users.

Only very few organizations seem to be enthusiastic about CentOS Stream. They tend to have their own OS team in house, which does its own OS release based on CentOS. In their case the Stream model made their life easier. The rest of users still seem to prefer the traditional release model.

Based on user feedback it seems, that most of our users will stay on RHEL and compatible operating systems. Some already made the switch: small companies changed from CentOS Linux to RHEL. But many larger installations running thousands of hosts are switching from CentOS to AlmaLinux. While others are switching to Rocky Linux and even Oracle Linux. And some to my favorite non-Linux OS: FreeBSD.

Friends vs. OS

While I have many friends in the Fedora and CentOS developer and user communities, these operating systems are just part of my syslog-ng work. To me it does not matter at all which OS people use to run syslog-ng. If suddenly all syslog-ng users started to use Slackware, I could easily drop my Fedora-related activities and focus on Slackware. Luckily, from the syslog-ng standpoint, support for RHEL, Alma, Rocky and Oracle is the same. I keep using the same tools, same workflows, and in bug reports I only see that people use packages from the Copr repository I maintain. No idea about the OS vendor.

TL;DR: The OS I support for syslog-ng and friendships are two completely separate things. Fedora made me many friends, and I’m grateful for that.
