openSUSE Tumbleweed es una distribución “Rolling Release” en desarrollo continuo. Aquí puedes estar al tanto de las últimas novedades.

TumbleweedVeamos un nuevo repaso a lo que ha ocurrido en esta semana a punto de acabar el mes de noviembre en openSUSE Tumbleweed.

openSUSE Tumbleweed es la versión “rolling release” o de actualización continua de la distribución de GNU/Linux openSUSE.

El anuncio original lo puedes leer en el blog de Dominique Leuenberger, en este enlace:

Las ISO’s son instalables, pero si ya estás disfrutando de openSUSE Tumbleweed en tu equipo, simplemente deberás actualizarlo mediante este comando aunque desde hace poco un simple zypper dup hace ya todo el trabajo.

En esta semana se han publicado 5 nuevas “snapshots” (1117, 1120, 1121, 1122 y 1123). Las “snapshots” 1118 y 1119 fueron bloqueadas por openQA yas que hubo algunos fallos al realizar los test automatizados.

Estas cinco nuevas publicaciones han traído entre otros muchos cambios, cosas tan interesantes como:

  • Kernel Linux 4.14.0
  • xfsprogs4.13.1 (actualizado desde la versión 4.9.0)
  • Se ha seguido en el trabajo de hacer /var un volumen separado de btrfs, simplificando el esquema de volúmenes
  • Mono 5.4.1
  • Java 1.7.0 OpenJDK ha sido eliminado, tal como se anunció

Muchas cosas se siguen tratando de actualizar y se esperan que estén en próximas “snapshots”

  • Kernel Linux 4.14.1
  • SCons cambia para utilizar python3 como intérprete
  • PostgreSQL 10
  • openSSL 1.1 de manera predeterminada para la distro
  • YaST/Storage-NG
  • Tumbleweed cambiará su suse_version de 1330 a 1550 el 1 de diciembre de 2017.

Si quieres estar a la última con software actualizado y probado utiliza openSUSE Tumbleweed la opción rolling release de la distribución de GNU/Linux openSUSE.

Mantente actualizado y ya sabes: Have a lot of fun!!

Dear Tumbleweed users and hackers,

Everybody is back from hack week – and it shows. In the last week, Tumbleweed had 5 snapshots released (1117, 1120, 1121, 1122 and 1123). Snapshots 1118 and 1119 were blocked by openQA as our autofs / NFS tests failed. Turned out to be an (intentional) change in the kernel. Once the issue was understood, the test was quickly adjusted to the new behavior and 1120 could be released without delays (if you’re interested, this was processed in bug 068916).

The five snapshots brought these updates:

  • Linux kernel 4.14.0
  • xfsprogs4.13.1 (upgraded from 4.9.0)
  • More work towards the goal of making /var a separate btrfs volume, simplifying the volume layout
  • Mono 5.4.1
  • Java 1.7.0 OpenJDK has been removed as announced

Many things mentioned last week in the ‘forging’ section are still work in progress:

  • Linux kernel 4.14.1 (snapshot 1124) and 4.14.2 (staged)
  • SCons changes to use python3 as its interpreter
  • PostgreSQL 10 to appear (just received a new set today, currently testing)
  • openSSL 1.1 as default for the distro (Amarok needs help/love)
  • YaST/Storage-NG
  • Tumbleweed will move its suse_version from 1330 to 1550 by Dec 1st, 2017.

La capacidad de mejora del Software Libre es asombrosa. Por ello la posibilidad de optimizar el uso de Dolphin, el gestor de archivos de Plasma 5, no tiene fin. Hoy os quiero presentar Convert WAV audio a MP3 un nuevo Service Menu para Plasma 5 que nos harán la vida un poco más fácil.

Convert WAV audio a MP3, nuevo Service Menu para KDE

De la mano de Alex-L nos llega un Service Menu que puede ser de gran utilidad ya que nos permitirá convertir archivos sonoros en formato wav al formato mp3.

Se trata de Convert WAV audio to MP3, el cual nos añade una línea al menú contextual de Dolphin que aparecerá cuando pinchemos con el botón derecho sobre un archivo wav. Un atajo de teclado que nos ahorra el deber de arrancar un programa para hacer una simple conversión.

Convert WAV audio a MP3, nuevo Service Menu para KDE

Convert WAV audio to MP3 se puede instalar directamente desde las opciones de “Añadir nuevos Servicios” del propio Dolphin, en el menú de configuración de la aplicación.

Y como siempre digo, si os gusta el service menu Convert WAV audio a MP3 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 Dolphin Service Menu?

La personalización de KDE y Plasma está más que demostrada y prueba de ello son los Dolphin Service Menu, que no son más que la posibilidad de disponer un menú auxiliar en el gestor de archivos Dophin o en Konqueror que se activa con el botón derecho del ratón.
Con ellos tendremos nuevas acciones como:

Y muchos más como hemos explicado en varias ocasiones en el blog. Puedes encontrar estos servicios se pueden encontrar en la sección Dolphin Service Menu en la Store de KDE.

I have been using Linux regularly since late 2003 as my daily driver, do-everything operating system. I have performed, many, many upgrades to many machines. Often, the nuke and pave route was my typical strategy. Upgrades often left a system partially working or with odd behavior. I like to fiddle with my Linux systems so my logic was to baseline after some time anyway. Over time, I haven't been fiddling is as much, mostly because there is no need and have just been using Linux to get work done and performing distribution upgrades have been my typical upgrade path.

After a considerable amount of distro hopping towards the end of Mandriva / Mandrake Linux as I knew it, I landed on openSUSE in 2011 for a variety of reasons but with mixed feelings. The community was warm but I had felt like I had abandoned those that went to the OpenMandriva, Mageia or even PCLinuxOS that I had known for several years. 

openSUSE has been a great distribution, helpful community, base technology and supporting systems are top notch. I would not consider myself a Command Line Interface power user but I am fairly comfortable hinging out in the terminal. Often, I don't have the patience to learn new commands or remembering specific system configuration commands. Thankfully there is YaST. It has been great for administering my system and has had many improvements over the years. Going from the Mandriva Control Center to YaST was an easy transition. YaST has made Linux life extremely easy and for that I am grateful.

Early this year (2017) I switched my primary machine from using openSUSE Leap to openSUSE Tumbleweed. I have enjoyed the comforts of the traditional static release for many years and have rarely had any problems with it but started to become more interested in this rolling release model that all the "kids" were talking about. So far, I can say I am extremely pleased.

Downsides

Not a downside for ME but could be a downside for some: Upgrades have to be done in the terminal... I think... maybe you can do them in YaST but I do them in terminal. I think that Tumbleweed is targeting a power user rather than the typical mass user.

It has become increasingly simple and approachable to perform upgrades in the terminal, with a simple: sudo zypper dup

The process has become much easier as the developers are very actively listening to the community. Depending on how many additional repositories you have added, there are occasions that may require user intervention and understanding of the software installed on your machine to resolve any version conflicts. This has not been a problem for me as I have clear understanding about what I have installed on my machine.

You must stay current on your upgrades. I haven't experimented as to see how long I can go between upgrading packages but I do believe this could be an issue.  Also, it is the point of

Warm white lightsWarm white lights
Since I’ve been playing with various home automation technologies for some time already, I thought I’d also start writing about it. Be prepared for some blogs about smart lighting, smart home and related technologies.

Most recently, I’ve gotten myself a few items from IKEA new product range of smartlight. It’s called trådfri (Swedish for wireless). These lights can be remote-controlled using a smartphone app or other kinds of switches. These products are still fairly young, so I thought I’d give them a try. Overall. the system seems well thought-through and feels fairly high-end. I didn’t notice any major annoyances.

First Impressions

Trådfri hub and dimmerTrådfri hub and dimmer

My first impressions are actually pretty good. Initially, I bought a hub which is used to control the lights centrally. This hub is required to be able to use the smartphone app or update the firmware of any component (more on that later!). If you just want to use one of the switches or dimmers that come separately, you won’t need the hub.
Setting everything up is straight-forward, the documentation is fine and no special skills are needed to install these smartlights. Unpacking unfortunately means the usual fight with blister packaging (will it ever stop?), but after that, a few handy surprises awaited me. What I liked:
Hub hides cablesHub hides cables

  • The light is nice and warm. The GU10 bulbs i got give 400 lumens and are dimmable. For my taste, they could be a bit darker at the lower end of the scale, but overall, the light feels comfy warm and not too cold, but not too yellow either. The GU10 bulbs I got are spec’ed at 2700 Kelvin. No visible flickering either.
  • Trådfri components are relatively inexpensive. A hub, dimmer and 4 warm-white GU10 bulbs set me back about 75€. It is way cheaper than comparable smartlights, for example Philips Hue. As needs are fairly individual exact prices are best looked up on IKEA’s website by yourself.
  • The hub has a handy cable storage function, you can roll up excessive cable inside the hub — a godsend if you want to have the slightest chance of preventing a spaghetti situation.
  • The hub is USB-powered, 1A power supply suffices, so you may be able to plug it into the USB port of some other device, or share a power supply.
  • The dimmer can be removed from the cradle. The cradle can be stuck on any flat surface, it doesn’t need additional cabling, and you can easily take out the dimmer and carry it around.
  • The wireless technology used is ZigBee, which is a standard thing and also used by other smarthome technologies, most notably, Philips Hue. I already own (and love) some Philips Hue lights, so in theory I should be able to pair up the Trådfri lights with my already existing Hue lights. (This is a big thing for me, I don’t want to have different lighting

The story so far

Two and a half years ago Collabora started to maintain LibreOffice in the Mac app store - checkout LibreOffice Vanilla: Fresh from the community to your Mac. This made it extremely easy and convenient to install LibreOffice on the Mac, and it is gratifying to see that around 365k users have indeed installed it.

As a company our raison d'etre is to drive the success of FLOSS, however in order to do that we need to raise funds to drive development. As such a major motivation here was to try to bring enough money into the Mac ecosystem that we could start to fix bugs, and address longer standing problems with the Mac - something everyone wants to see.

To try to achieve that we included a risque 'nag' dialog, that would encourage people to donate to The Document Foundation (TDF) - and also encourage them to buy Collabora Office on the Mac to help fund engineering work. This would show up on first-start, though we moved that to monthly, and remind Mac users that while so many contribute so much of far greater value than money to code, docs, l10n, QA, UX, and in many other ways, nevertheless the quickest & easiest way to make a small contribution if you're missing the skills is with a small donation to TDF, or failing that by buying a paid Collabora Office through the app-store.

Today's numbers

Each month we have on average 54 people purchasing Collabora Office for Mac for $10 (we get 70%), and around 10 donation page visits per month that we could track, TDF's average donation is around $10. So estimating this is around $380 per month of income for Collabora, and say $100 for TDF.

That doesn't sound too terrible, until you look at this two ways:

  1. The cost to Collabora - of the up-front investment needed to get the Mac build sandboxed as well as ongoing costs to work around changes to the sandbox, as well as fixing nits that reviewers find each time we submit a new version. So far that cost between two and three times the income (at cost ) - so quite some loss. This explains why we have not been investing as we'd like to in keeping LibreOffice Vanilla up-to-date.
  2. The cost to TDF - what cost you say ? they got $100 per month for nothing. Well yes, and no. TDF serves install sets at around 50k per day - that is around ~20 million per year. TDF's awesome donors gave around Eur 800k last year to drive its mission - so around Eur 4 cents each download (though user counts could be significantly greater). So from 12k downloads per month, we'd expect $485 in donations from this many Mac downloads, assuming an average generosity of Mac users.
So - this current situation seems to be a lose-lose for Collabora and TDF, with only Apple winning its 30% cut. That is far from ideal - we didn't go into business

The past week brought new features to openSUSE Tumbleweed with a snapshot that included Linux Kernel 4.14. New features like HDMI Consumer Electronics Control support for Raspberry Pi and the merging of Heterogeneous Memory Management to the mainline this Long-Term Support Kernel are promising.

openSUSE’s rolling distribution produced four openSUSE Tumbleweed snapshots this week and brought many other goodies.

Topping off the latest snapshot, 20171121, was a service release of mono-core 5.4.1. Mono,  which is the open source implementation of Microsoft’s .NET Framework based on the ECMA standards for C# and the Common Language Runtime, provided a handful of bugfixes. Code-cleaning in setup.py was made available with the update to python-ldap 2.5.2. The administration and debugging tool for the XFS file system had an enormous amount of updates with the xfsprogs 4.13.1 version, which has new extent lookup helpers.

The 20171120 snapshot, which provided Linux Kernel 4.14, had updated versions for the IP lookup program GeoIP and the expat library. GeoIP 1.6.11 provided a fix for the use of a NULL pointer when opening a corrupt database with GeoIP_open and expat 2.2.5 provided several fixes including a security fix. Text editor GNU nano introduced the ability to record and replay keystrokes with version 2.9.0 and python-setuptools 36.7.2 fixed duplicate test discovery on Python 3.

KDE users received KDE Applications 17.08.3 this week in the 20171117 and 20171116 snapshots. The newest applications from the KDE community include bugfixes include improvements to Kontact, Ark, Gwenview, KGpg, KWave, Okular and Spectacle. Okular no longer crashes after certain rotation jobs and archiver Ark preserves file modification dates when extracting ZIP archives. The file system utilities for maintaining the ext2, ext3 and ext4 file systems, e2fsprogs, updated to version 1.43.7 and fixes of error handling in journal replay as well as updated translations. The replacement of the NIS library that used to be in GlibC, libnsl 1.2.0, made the code more portable.

Mozilla’s Firefox Quantum 57.0, which has a redesigned interface, arrived in snapshot 20171116. The new browser takes full advantage of the processing power in modern devices, according to the release notes. In addition to the multiple updated to Applications 17.08.3 released in snapshot 20171116, KDE Framworks 5.40.0 also arrived in the snapshot and provided serveral functionality fixes. Among other packages updated in the snapshot were python-jedi 0.11.0, python-kiwi 9.11.17 and rsyslog 8.30.0, which now handles (JSON) variables in case-insensitive way and fixes a memory corruption during configuration parsing.

As we reported in one of our last news, we setup a new galera cluster for all our applications that make use of MySQL. This cluster should allow us to do maintenance on one of the cluster nodes at any time - and also should scale the workload between the nodes, via the HaProxy in front.

One problem, that affected us for example in case of progress.opensuse.org, are the MyISAM tables: Galera is not really ready (yet?) to sync the content of such tables (even if you can enable the "experimental" feature, if you don't care much about your data). As result, we do not only need to have a look and migrate each an every single MyISAM table - but more worse, we also need to have a look at the used code of the application to identify problematic SQL statements (like DELAYED inserts for example) - and patch it where needed.

But the good news for the two databases mentioned: so far everything seems (still) to work. Other applications will follow one by one (as some like connect need adaptions).

La forma que tenemos de aprender a hacer las cosas está cambiando. El papel del profesor está cambiando y de transmisor de conocimientos está pasando a guía para filtrarlos. Es algo que entiendo y asumo, no por nada soy docente con casi 20 años de experiencia en este mundillo. Es por ello que me encanta encontrar recursos educativos como el curso Kdenlive de Kalerolinex, una excelente herramienta para aprender a dominar este magnífico editor de vídeos no lineal de la Comunidad KDE.

Curso Kdenlive de Kalerolinex

Un curso de cualquier cosa en forma de vídeos didácticos que empezó en 2010 y que sigue vigente este 2017 es algo a tener en cuenta. Es que es de recibo agradecer a Kalerolinex todo el trabajo realizado para mostrar a todo el mundo como empezar con Kdenlive y, lo más importante, seguir hasta dominar con soltura esta magnífica aplicación de edición de vídeo.

Curso Kdenlive de Kalerolinex

Esto significa que puede que alguna cosa esté desactualizada respecto al funcionamiento actual de la aplicación, esto no es bueno, pero lo más importante es que su creador ha seguido a lo largo de estos años creando con una aplicación que ha pasado de sencilla e inestable a potente y confiable.

A modo de resumen os puedo contar que de momento el curso Kdenlive de Kalerolinex lleva 33 capítulos y que nos explica cosas como aprender a manejar la ventana del árbol de proyecto o como hacer Presentaciones didácticas como en la TV – Efecto Cromakey pasando por la utilización de Impress para crear entradas y salidas en Kdenlive, último de ellos creado.

Y para muestra, el primer capítulo del curso de Kdenlive de Kalerolinux donde básicamente nos explica como iniciar la aplicación y una descripción de la interfaz de usuario. Todo ello en perfecto castellano. He de confesar que he utilizado este recurso para que mis alumnos aprendan algo de edición de vídeo.

Y como siempre digo, si os gusta  el trabajo de Kelerolinux podéis “pagarlo” de muchas formas el creador agradecerá: puntúale positivamente, hazle un comentario en la página, dadle un like o subscríbete a su canal. 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.

El incidente Max Headroom se llevó a cabo en 1987 en un par de cadenas de televisión en las que su señal fue atacada con un “Man-In-The-Middle”

Hoy navegando por la web entre artículos antiguos de diversas webs, he encontrado en una de esas web, una referencia al incidente Max Headroom. Un caso de interferencia en la señal de una cadena de televisión.

Desconocía el caso, así que me dirigí a la Wikipedia a leer sobre el asunto, si vosotros tampoco conocíais este incidente y serie de televisión os recomiendo la lectura.

El Incidente Max Headroom fue una señal intrusa de televisión que tuvo lugar en Chicago, Illinois en la noche del domingo 22 de noviembre de 1987. Es un ejemplo de lo que se conoce en el negocio de la televisión como intrusión en emisión de señal. El intruso logró interrumpir dos estaciones de televisión abierta en el transcurso de tres horas. Los responsables nunca fueron identificados.

El caso es un tipo de inyección de señal de televisión en una emisión de una cadena pública. Algo que para hacerse se necesita de conocimientos técnicos, de el equipo adecuado y de la potencia necesaria para realizarlo.

Como no tengo más información sobre el caso, os remito de nuevo al artículo de la Wikipedia, y a que vosotras mismas (personas geeks, hackers inquietas) indaguéis al respecto.

En el vídeo (de YouTube, lo siento) que abre el artículo podéis ver la señal inyectada en la emisión de televisión, mientras se emitía un capítulo del Dr. Who.

Gracias a que seguidores de la serie estaban grabando el capítulo se ha podido rescatar la emisión “inyectada”. Es un caso de hacking de “man in the middle” en televisión.

Además me parece curioso que justo cuando me entero del curioso incidente se cumplan 30 años del mismo… curiosas coincidencias.

Vuelve la sección de los pequeño trucos para optimizar nuestro trabajo con el escritorio Plasma. En esta ocasión quisiera explicar cómo utilizar ssh en Dolphin, es decir, como acceder de forma gráfica a carpetas de otros sistemas mediante el protocolo ssh y poder así tener un control más visual de éste.

Cómo utilizar ssh en Dolphin

Mientras termino de perfilar un artículo sobre mi sistema multimedia hogareño y sigo aprendiendo cositas para mejorar su uso, voy descubriendo métodos de trabajo que me hacen la vida más fácil.

Una de ellas es poder controlar mi Rapsberry Pi del Salón de forma remota utilizando mi ultrabook o cualquier PC que esté en mi red local. Para ello puedo utilizar el protocolo Samba pero quería ir un poco más allà y utilizar el protocolo ssh.

Cómo conectar Raspberry Pi con Dolphin

Evidentemente, lo primero que hice fue buscar por internet la forma de hacerlo y rápidamente me di cuenta que necesitaba un par de datos antes de empezar: la dirección ip de la raspeberry pi en mi red local y el nombre de usuario y contraseña de la misma Raspeberry.

El primer dato lo debes sacar de tu red pero será parecida a 192.169.x.x., el segundo suele ser pi como nombre de usuario y raspberry como password.

Antes de seguir con el método de conexión debo advertir que debemos asegurarnos que tenemos activado en servidor ssh en la raspberry y el paquete openssh-server en la máquina que se conecta.

En mi caso, desde mi portátil con KDE Neon, que no es más que un Ubuntu 16.04, simplemente debo escribir esto en la consola:

$ sudo apt install openssh-server

Con estos datos ya podía seguir las instrucciones de la red, que consistían siempre en “Escribe esto en la barra de direcciones de Dolphin: fish://pi@192.168.x.x/home/pi/”. Lo cual es correcto y que funciona a la perfección, como podemos ver en la imagen inferior.

Cómo utilizar ssh en Dolphin

La única pega, en mi humilde opinión, es que si no carga demasiado el sistema, todas las opciones de protocolos de conectividad deberías estar listos para utilizar a la primera. No obstante, tampoco debería quejarme tanto ya que si todo fuera perfecto ¿para qué serviría KDE Blog?

Yesterday Google invited everyone who is interested in cloud technology to its office in Munich. Cloud OnBoard is a free, full-day training event, where Google introduces its “Google Cloud Platform”. Well… what can I say… That was amazing. Well organized, well presented. I love it. I never worked with GCP before. This event included not only in-depth technical presentations about every part of the platform, but also demonstrations, examples, questions and exercises for participants.

Google Cloud Platform includes not only typical cloud parts that has, for example, OpenStack, but also supports BigData components. Yes, it’s compatible with API of Hadoops ecosystem. That was a nice surprise for me. When I visited some Cloud or BigData events or workshops I asked myself all the time why these technology can’t be merged. I missed an easy way to add new nodes to the Hadoop-cluser that could to analyze installed already components and add needed components to the new node of the cluster automatically. That’s exactly where cloud used for. On another hand, that will be very useful to analyze data about existing cloud on the cluster and change/reconfigure a cloud if it’s needed automatically.

Some features are sill under development, but all what was presented is very impressive. Just one thing makes me sad: some components of the platform are proprietary software 🙂 It makes platform unusable to hack and learn it in depth at home… On the other hand, Google is trying to create community around an platform and open the source code of some components like gcloud or Google App Engine. Some technologies used inside an platform like Docker and Kubernetes are 100% Free Software.

At the end everybody got certificates. Thanks for that!

Google Cloud Platform training accelerates your understanding of and ability to use the Google Cloud Platform services. By the way, today OnBoard meeting find the place in Google’s office in Hamburg and in 2 weeks I’m going to Google Cloud Summit 2017 in Munich. See you there 😉
