Snapshots of openSUSE Tumbleweed rolled out consistently this week.

The rolling release put out a snapshot everyday since Oct. 12 and this week brought a few major version updates as well as an update of KDE’s Gear.

The latest snapshot 20221019 came out a few hours ago and updated the Common Internet File System and user-space tool cifs-utils 7.0. The update fixed some warnings that included a compiler warning as well as the package fixing some memory allocation. The Netscape Portable Runtime package mozilla-nspr updated to version 4.35, and it had fixes for building with clang compiler. The package also uses a number of online processors on certain platforms. Mozilla’s mozilla-nss updated to version 3.83. The Network Security Services package removed older unix support, added two DigitalSign root certificates and changed configuration settings behavior to skip configs with unsupported mandatory extensions instead of these failing; this was focused on Encrypted Client Hello extensions. A few other packages updated in the snapshot.

GNOME’s encryption interface Seahorse updated to major version 43 in snapshot 20221018. This package joined the several other GNOME 43 Guadalajara packages that are already in the rolling release. The package fixed warnings related to authorized keys, and it disabled key sharing over DNS Service Discovery by default. An update of gpg2 2.3.8 fixed a problem with Yubikey 5.4 firmware and fixed a regression in READKEY --format=ssh. An update of libsoup 3.2.1 fixed a minor memory leak and libxml2 2.10.3 fixed an integer overflow, which addressed CVE-2022-40303; this had no effect on OpenStack Cloud’s 8 and 9. And cfg80211, which is configuration Application Programming Interfaces for 802.11 devices in Linux, had some changes with the 6.0.2 kernel-source update. It fixed a Block Starting Symbol refcounting bug and avoids a non-transmitted BSS list corruption. A change was made with the nodejs18 18.11.0 update; it added an experimental watch mode. Running in watch mode using node, watch restarts the process when an imported file is changed. Several other packages updated including libzypp 17.31.4, libgcrypt 4.4.28, yast2-network 4.5.9 and more.

Two packages updated in snapshot 20221017. Podcasters using Tumbleweed will see the latest audio editing package update for audacity. The 3.2.1 countdown version fixes some bugs and has minor improvements. One of those fixed the crashing of the startup on some systems and a freeze when very quickly starting and stopping playback. The C Library for manipulating module metadata files, libmodulemd, updated to version 2.14.0 and it has new functions for stripping XMD from an index.

KDE users had their second consecutive update of Gear 22.08.2 in snapshot 20221016. Gear 22.08.2 updated several packages. File archiver Ark stopped killing extraction/compression jobs when dolphin quits. The itinerary package updated the current reservation identification of the event page when changing tickets and explicitly positioned the event ticket header fields. Multiple updates were made with Gear’s new kalendar version, like fixing the double-click to edit in the tasks view and implementing the use of standard keys for viewing navigation actions. Gear’s video editor Kdenlive made several changes including the timecode display, so it listens to the profile change and automatically adjusts frames per second. The package also fixed the pasting effect with keyframes that were partially broken. The lightweight C library for storing RDF data in memory, sord 0.16.14, fixed an issue that accidentally exposed internal zix symbols. The first stable release arrived with the gcr 4.0.0 major version update; not much info was provided in the changelog. Other updates in the snapshot were made to perl-HTML-Parser 3.79, perl-HTTP-Message 6.41, perl-JSON 4.10 and more.

Most of the KDE Gear 22.08.2 packages arrived in snapshot 20221015 and just a few other packages updated in the snapshot. The 4.5.46 version of libstorage-ng merged a change that allows it to work with other linux flavors. There were also updates to libzypp 17.31.3, yast2 4.5.17 and more.

Both 20221014 and 20221013 snapshots had multiple package updates. The update of ethtool 6.0, which is a utility for controlling network drivers and hardware, fixed advertisement modes autoselection. The 3D graphics package Mesa 22.2.1 implemented the Vulkan 1.3 API and fixed regressions with the open-source Sony PlayStation 3 emulator RPCS3 where nothing was being rendered. An update of yast2-bootloader 4.5.7 prevents the leak of grub2 password to the logs. The 7.1.0.50 update of ImageMagick added a private API to go through a linked list without using semaphores, and it has the latest automake configuration.

Una reciente campaña de asistencia médico-quirúrgica en Senegal por parte de una Organización No Gubernamental destaca los beneficios del uso de software libre

Un equipo de Cirugía Solidaria, que es una ONG que brinda asistencia médica en países desfavorecidos junto con otras actividades de promoción de la salud, realizó una campaña del 23 de septiembre al 3 de octubre con la Fundación Elizabeth Diouf.

La campaña involucró a varios profesionales médicos que realizan asistencia médica utilizando las tecnologías de software libre que ofrecen GNU Health y el proyecto openSUSE.

El uso de GNU Health, que es un Sistema de Información de Gestión Hospitalaria, permitió que el equipo multidisciplinario, que incluía enfermeras, cirujanos, pediatras, ginecólogos y otros profesionales, organizara y facilitara la atención médica diaria durante la campaña de asistencia médica.

La tecnología en los dispositivos del equipo y la impresora que se ejecutaban en un servidor local usando como sistema operativo del servidor openSUSE, y esto le dio al equipo la máxima oportunidad de organizar, evaluar y tratar a los pacientes.

Los 10 días ininterrumpidos de operación simultánea con cuatro consultas, cinco mesas quirúrgicas, una sala de reanimación y unas 40 camas de hospital permitieron al equipo atender a 1.200 pacientes de diferentes distritos y regiones de Senegal, así como realizar unas 370 cirugías, incluidas 77 para niños, entre ellas 8 eran urgentes.

Este es el segundo programa de salud en África que se ha destacado utilizando el softwarela unión de dos proyectos de software libre como son: GNU Health y openSUSE.

El año pasado, miles de pacientes en la zona costera de Kribi, Camerún, en el Hospital Ebomé utilizaron estas soluciones de software libre, como empoderamiento local para expandir la prestación de atención médica en África Occidental.

Se espera que algunos miembros del equipo y miembros de GNU Health y openSUSE asistan a la Conferencia de GNU Health el próximo mes.

Es de verdad una gran noticia, ver cómo unas comunidades de software libre se unen y apoyan a los voluntarios de algo tan importante como la salud en países olvidados de las portadas de las noticias, donde el saqueo, la corrupción interna y los conflictos de su país han provocado grandes carencias y sufrimiento.

En vez de ser campañas esporádicas que solucionen algunos problemas, deberían ser programas a largo plazo, pero supongo que como siempre, habrá una dejadez y falta de recursos que lo hará muy difícil. Espero que se pueda ir cambiando eso.

Llegando a los 205 plasmoides con Relaxing Sounds for KDE, una miniaplicación que nos permite estar un poco más relajados cuando estemos trabajando con nuestro ordenador. Nota:Esta entrada aparece después de la 206 por un error.

Relaxing Sounds for KDE – Plasmoides de KDE (205)

Por norma general los plasmoides sirven para decorar, ampliar funcionalidades o proporcionar información. No obstante casi siempre pensamos en ellos en términos visuales y pocas veces en términos auditivos.

Hace poco rompí esa dimensión presentando Trumpet Test Audio en el blog, y hoy toca hablar de Relaxing Sounds for KDE, un widget creado por rrayagjain en el que puedes poner sonidos relajantes para los amantes de la naturaleza, que puedes escuchar mientras trabajas, duermes o estudias.

Además, el plasmoide te permite añadir tus propios sonidos, con el que persoalizarlo es solo cuestión de esfuerzo… es más, os ahorro tener que buscarlos muchos ya que los podéis encontrar en Freesound.

Y como siempre digo, si os gusta el plasmoide podéis “pagarlo” de muchas formas en la cambiante 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.

Almost one month after our latest update, here it comes a bunch of news from the YaST Team trenches. And, as usual, we fire in many directions including:

• Several news about D-Installer
• An update about the new Security Policies in the YaST installer
• An effort to streamline a bit the YaST container
• Some polishing of Podman checkpoints

So let’s go into the details.

Fueling the D-Installer Project

Some months ago we presented our proof of concept for a future Linux installer codenamed D-Installer. Since then, we have scattered news about it on our blog posts. Now we decided it’s the right time to invest a bit more in the project in order to move it forward.

As a first step, we improved the README file that serves as landing page for the project. Now it includes more information about the motivation and general structure of the project, as well as some screenshots of the web interface.

We also designed the D-Bus and web interfaces for defining the storage setup. That is, the set of partitions, LVM logical volumes and related data structures that should be created to install the system on. We published a document describing how it could work and we are already implementing that behavior. So if you have questions or suggestions, please speak up the sooner the better.

We are also making good progress in the configuration of the network, but since the feature is not complete yet we will save those news for upcoming blog posts. ;-)

On a more technical level, we introduced type checking in the JavaScript part of D-Installer by relying on TypeScript support for JSDoc annotations. If you don’t care about software internals, the previous sentence is just gibberish you can happily ignore. But if you are a JavaScript developer working on a project that is growing a bit too much, you may be interested in checking our approach in order to take advantage of the most important feature of TypeScript without actually changing the implementation language of the project.

Security Policies in the YaST Installer

Although we envision D-Installer as the future of (open)SUSE installation, we never forget YaST is still the present and will remain so for some years. Therefore we keep enhancing it and adapting it to new use cases. Lately we invested some time polishing the feature about security policies we originally presented some posts ago, based on the feedback we keep receiving about it.

As you can see in the screenshot below, now the initial scan performed in the first boot after installation is configurable and can even be skipped in order to be run manually afterwards. Additionally we changed the way the failing rules are presented and the way to acknowledge the situation in order to continue with the installation anyway. Moreover we extended the help texts to better explain the rationale and implications of each option.

You can check up-to-date information about the feature and several current screenshots (bear in mind they are collapsed by default) at this pull request.

A More Container-friendly iSCSI Client

The containerized version of YaST includes several modules that are known to work correctly when executed from a container. But “correctly” does not always imply “optimally”. For example, the module for configuring iSCSI clients required some iSCSI tools to be installed both in the system to be managed (as expected) and in the container itself. That impacted the size of the YaST container, even for those who were not interested in executing yast2-iscsi-client. Moreover, while investigating that circumstance, we found the dependencies of the package were not aligned with YaST best practices. All that is fixed now and we have a more maintainable and standardized YaST iSCSI Client and a smaller YaST container.

Helping to Fix Problems with Cockpit and Podman Checkpoints

Talking about system management tools, you already know our team is lately looking beyond YaST and trying to help with the maintenance and integration of Cockpit. As a consequence of that continuous effort, we realized the functionality for creating checkpoints for Podman containers was not working as expected neither in openSUSE Tumbleweed nor in the ALP prototypes due to some problem in the package criu. Fortunately we are surrounded by people smarter than us, so we contacted Takashi Iwai and helped him to diagnose the problem. As a result, criu and Podman checkpoints are now working again in both Tumbleweed and the ALP prototypes. But don’t ask us for technical details, it’s all Takashi’s merit.

More to Come

We keep working in all the areas related to system installation and configuration, so we hope to be back soon with more news about D-Installer, Cockpit and, of course, YaST. Meanwhile do as chameleons do and have a lot of fun!

Recently I had a first look into Vulkan development. So I started by reading a Vulkan Tutorial. It’s rather detailed and actually it takes a long time before you see your first shaded triangle (about 900 lines of code!). The Vulkan Tutorial has some software requirements on Linux, which are explained in detail in the Development environment for Linux. In order to make things easier for openSUSE users here is the package list you need to have installed. Just install them via zypper.

Since the tutorial is using C++ …

# if you don't have the C++ compiler installed yet
zypper in gcc-c++

Vulkan packages

zypper in vulkan-tools vulkan-devel vulkan-validationlayers libvulkan_intel libvulkan_radeon

Shader Compiler glsc for generating SPIR-V binaries

zypper in shaderc

GLM library needed for linear algebra operations (not included by Vulkan, but also popular on OpenGL)

zypper in glm-devel

GLFW library for window handling, etc. used by the Tutorial (Vulkan is platform-agnostic!)

zypper in libglfw-devel

Other needed packages since mentioned in the sample Makefile of the Tutorial

zypper in libXi-devel libXxf86vm-devel

And now have fun with the Vulkan Tutorial ! :-)

Toko (kios) pertanian Zeze Zahra sudah buka menjelang akhir bulan September 2022. Sudah sekitar 2-3 minggu. Selain toko offline, saya juga berusaha memaksimalkan toko online, https://tokopedia.com/zezezahra.

Proses yang dilakukan saat ini adalah menambahkan dan mengupload foto semua produk dan layanan yang disediakan pada toko offline, karena masih banyak yang belum diupload.

Benih tanaman masih ada sebagian yang belum dimasukkan ke list produk. Belum lagi polybag, pot tanaman, obat tanaman, bibit jambu Madu Deli maupun jambu Dalhari, bibit pepaya California, bibit Cempedak, sekam bakar, media tanam, anakan ayam hingga minuman tradisional.

Proses upload produk jadi terhambat karena saya harus membuat foto, menuliskan judul, deskripsi hingga menentukan harga jual. Ditambah lagi dengan kesibukan pekerjaan di Excellent dan Aktiva serta adanya tugas kuliah yang harus diselesaikan.

Jadi saya harus belajar. Belajar mendelegasikan pekerjaan. Saya sudah belajar hal itu di Excellent dan Aktiva, tapi di Zeze Zahra masih saya lakukan sendiri karena ini masih awalan. Saya khawatir team saya di Zeze Zahra bingung, misalnya dalam menentukan harga.

Saat kuliah materi Machine Learning, saya jadi belajar lagi konsep delegasi. Pada machine learning, kita bukan melakukan segalanya sendiri sampai kecapekan, melainkan mendelegasikan pekerjaan pada si mesin, dengan cara menentukan kriteria dan memberikan contoh. Nanti si mesin akan belajar menentukan sendiri.

Kalau kita sudah training, si mesin bisa kita ujicoba dengan data pembanding (dataset), apakah sudah lulus atau belum.

Mekanisme itu yang akhirnya saya gunakan, supaya pekerjaan bisa selesai dan saya juga tidak kewalahan.

Sebagai contoh, saya minta Satir dan Adul untuk menambahkan produk “Media Tanam”. Saya cukup memberikan kriteria sebagai berikut :

1. Judul produk harus menarik tapi tidak menipu

2. Deskripsi harus sesuai fakta, jangan berlebihan. Misalnya menulis “Media tanam cocok untuk semua jenis tanaman…”

Lho bagaimana kita bisa tahu? Semua jenis tanaman? Banyak sekali jenisnya dan ada kemungkinan tidak cocok. Saya sarankan untuk mengganti kata-katanya menjadi : “Cocok untuk berbagai jenis tanaman”

Berbagai jenis tanaman itu bukan semua, tapi lebih dari satu. Minimal sudah diujicoba pada bibit anggur, pepaya, cempedak, cabe dan lain-lain

3. Foto harus menarik, usahakan foto milik sendiri bukan mengambil dari tempat lain apalagi mengambil dari toko orang lain, hehehe…

Lebih baik lagi jika foto disertakan berbagai jenis, misalnya ada foto benih, bibit dan foto saat tanaman berbuah. Jadi lebih menarik.

Masalahnya, tidak semua benih sudah diujicoba, jadi proses foto ini akan dilengkapi bertahap.

4. Penentuan harga jual. Ini bagian paling sulit. Kalau terlalu murah bisa nombok. Kalau terlalu mahal jarang yang mau beli. Bagaimana tipsya menentukan harga jual?

Tipsnya sama dengan saat saya menentukan harga jual pisang di Aneka Pisang Zeze Zahra atau saat menentukan harga layanan di Excellent dan Aktiva.

Pertama, pastikan harga beli atau modal

Kedua, check apakah ada biaya lain misalnya biaya transport, biaya menurunkan barang dll. Biaya ini bisa per satuan bisa juga bulk atau gabungan.

Misalnya saya membeli benih harga dasar anggaplah 100 rupiah. Saya memesan 1 dus benih berisi 500 kemasan kantong dengan biaya pengiriman 500 rupiah. Berarti biaya HPP atau harga pokok adalah 101 rupiah per kantong, terdiri dari harga benih 100 rupiah dan biaya pengiriman 1 rupiah per benih.

Setelah mendapatkan HPP, tentukan margin. Ini bisa dilakukan dengan cara mengecek harga umum. Biasanya saya mengambil beberapa sample harga dan mengambil nilai rata-rata.

Dari hasil itu baru didapat harga jual yang reasonable atau masuk akal. Apakah itu berarti pasti lebih murah? Belum tentu, karena bisa saja malah lebih tinggi dibanding toko lain, namun masuk akal dan ditambah lagi dengan jaminan kualitas.

Apakah kita selalu membeli mobil termurah di pasaran? Mwmbeli baju termurah, sepatu termurah, makanan termurah? Belum tentu juga kan. Pada banyak situasi, kita pasti mempertimbangkan kualitas produk dan layanan juga.

Telur bebek misalnya, di tempat lain bisa didapat dengan harga dibawah 2500 rupiah. Bisa selisih 50, 100 atau bahkan bisa selisih 500 rupiah. Bisa saja selisih itu karena ada keharusan membeli dalam jumlah minimal quantity tertentu atau ada hal lain.

Saya tidak khawatir soal perbedaan harga karena saya pribadi tidak selalu memilih harga termurah, asal tidak terlalu jauh bedanya. Jangan sampai sudah mahal harga, kualitasnya juga jelek pula 🤭😂

Dengan menentukan kriteria, saya bisa melatih team saya di Zeze Zahra untuk melakukan pekerjaan yang biasa saya lakukan. Saya jadi lebih leluasa dan disisi lain team saya punya kewenangan dan tanggung jawab lebih luas. Saya hanya perlu melakukan pengecekan dan monitoring berkala.

Hace apenas un día que me he enterado que mañana 20 de octubre se va a realizar la «IX Jornada de Usuarios de R en Galicia», un evento de corte técnico de, según la wikipedia, el entorno y lenguaje de programación con un enfoque al análisis estadístico. Si estáis por la zona, no os lo perdáis, sino a seguirlo en vivo o a esperar los vídeos.

IX Jornada de Usuarios de R en Galicia

He conocido el evento al escuchar el gran podcast de 24H24L dedicado a ámbito científico en el cual hablaban de este evento que tiene ya casi una década de vida.

Según sus organizadores (traducido del gallego desde el traductor de la Xunta):

La IX Jornada de Usuarios de R en Galicia tendrá lugar el día 20 de octubre de 2022 en el Aula Magno de la Facultad de Matemáticas de la Universidad de Santiago de Compostela.

Organizada por la Asociación de Usuarios de Software Libre de la Terra de Melide (MeLiSA) y patrocinada por la AMTEGA (Xunta de Galicia), como en ediciones anteriores incluirá relatorios sobre temas de actualidad con el objetivo de promocionar el conocimiento del lenguaje estadístico R y sus aplicaciones, así como proporcionar un punto de encuentro para todas aquellas personas interesadas en intercambiar sus experiencias y encontrar colaboraciones del resto de la comunidad.

De esta forma, ya está publicado el programa, que empieza a las 9:00 y finaliza a las 19:30, lo cual demuestra la densidad de información que podremos recibir de esta interesante jornada.

Si no podéis seguirlo en vivo en Santiago de Compostela no os precupéis ya que será retransmitdo por el siguiente cana de youtube.

NUREMBERG, Germany, Oct. 19, 2022 - A recent campaign of medical-surgical assistance in Senegal by a Non-Governmental Organization highlights the benefits of using open-source software.

A team from Cirugía Solidaria, which is an NGO that provides medical assistance in disadvantaged countries along with other health promotional activities, conducted a campaign from Sept. 23 to Oct. 3 with the Foundation Elizabeth Diouf.

The campaign involved several medical professionals carrying out medical assistance while using open-source technologies from GNU Health and the openSUSE Project.

The use of GNU Health, which is a Hospital Management Information System, allowed for the multidisciplinary team, which included nurses, surgeons, pediatricians, gynecologist and more, to organize and facilitate daily medical care during the medical assistance campaign. The technology on the team’s devices and the printer that were all running on a local server using openSUSE, and this gave the team maximal opportunity to organize, evaluate and treat patients.

The 10 uninterrupted days of operating simultaneously with four consultations, five surgical tables, a resuscitation room and about 40 hospital beds allowed the team to see 1,200 patients from different districts and regions of Senegal as well as perform about 370 surgeries, which included 77 for children; eight were urgent.

This is the second health program in Africa that has been highlighted using GNU Health and openSUSE software. Last year, thousands of patients in the coastal area of Kribi, Cameroon, at Ebomé Hospital used these open-source solutions to expand health-care delivery in West Africa.

Some of the team and members from GNU Health and openSUSE are expected to attend the GNU Health Conference next month.

The openSUSE Project has begun its annual elections process that will fill three board seats to represent the project’s governance.

Phase 0, which is the announcement of the elections and the call for candidates/nominations, started Oct. 15. This phase aims to get people involved with the project to consider serving as a representative for fellow openSUSE community members.

“Fellow Geeko’s now is the time to put forward your candidacy for the three available seats on the board this year!” wrote the election committee to the project mailing list.

To stand for a position on the openSUSE board, people are asked to send an email to project@lists.opensuse.org and election-officials@lists.opensuse.org.

“Only openSUSE members are eligible to run for openSUSE Board openings,” according to the openSUSE wiki.

This phase will end at the end of the month, which will move the election process to Phase 1. Phase 1 publishes the candidate slate and the campaigning begins.

Board members help with the governance of the project and assist the community with a variety of topics and responsibilities.
