  • Ubuntu Server development summary – 29 October 2019

    The purpose of this communication is to provide a status update and highlights for any interesting subjects from the Ubuntu Server Team. If you would like to reach the server team, you can find us at the #ubuntu-server channel on Freenode. Alternatively, you can sign up and use the Ubuntu Server Team mailing list or visit the Ubuntu Server discourse hub for more discussion.

  • Peruvian International Scientific Meeting: Sinapsis 2019

    The first speaker pictured is Prof. Jorge Chau from the Leibniz Institute in Germany and his talk named “Studies of mesospheric and lower thermospheric turbulence and waves with novel multi-static MIMO specular meteor radars”. He made a thoughtful and impassioned explanation of his work. This time I understood maths and its application. My second favorite talk was given by Lucia Fitts Vargas. She talked about “Effects of disturbances and land used change on carbon stocks in six US states ” from the University of Minnesota. I liked her talk because she was able to explain in a very simple way the presence of carbon in trees in our jungle in Peru and then she gradually jumped to the complexity explanation about her carbon stock research and tools used in the USA. I was impressed by the research of Jacqueline Valverde Villegas from INSERM, Université de Montpellier, France about the HIV: “Aspectos genéticos e inmunológicos en la infección por el VIH/SIDA”, and the work of Juan Carlos Hurtado from the University of Barcelona: “Identificación de las causas de muerte en países de mediana y baja renta a través de la autopsia mínimamente invasiva”. I overheard good acceptance for the talk of Dr. Luis Dalguer about the earthquakes prediction in Switzerland: “Terremotos: su mecanismo físico, su predicción y prevención de desastres”. Lastly, the talk of Lucila Menacho from the University of Engineering in Peru named “Study, construction, and applications of supercapacitors based on graphene” was an interactive talk that everyone in the room paid attention. Congrats in general to all because all they were interesting topics.

  • FOSDEM 2020 Real-Time Communications Call for Participation

    You can use HTML and links in your bio, abstract and description.

    If you maintain a blog, please consider providing us with the URL of a feed with posts tagged for your RTC-related work.

    We will be looking for relevance to the conference and devroom themes, presentations aimed at developers of free and open source software about RTC-related topics.

    Please feel free to suggest a duration between 20 minutes and 55 minutes but note that the final decision on talk durations will be made by the devroom administrators based on the number of received proposals. As the two previous devrooms have been combined into one, we may decide to give shorter slots than in previous years so that more speakers can participate.

    [...]

    Generally, it was a good experience. I have not seen another peruvian in person more than a year and living again for a week with Wilson Valerio, Martin, Lucas, Alisa and others, made me remember my roots and way I am in Europe. I am glad I tried the best chocolate!

  • The best (and worst) ways to influence your open community

    After you've established a positive reputation in an open community—hopefully, as we discussed in our previous article, by being an active member in and contributing productively to that community—you'll have built up a healthy "bank balance" of credibility you can use to influence the direction of that community.

  • SourceForge download issues (and Github issues issues)

    There are two high-priority problems currently affecting TenFourFox's download and development infrastructure. Please don't open any more Tenderapp tickets on these: I am painfully aware of them and am currently trying to devise workarounds, and the more tickets get opened the more time I spend redirecting people instead of actually working on fixes.

    The first one is that the hack we use to relax JavaScript syntax to get Github working (somewhat) is now causing the browser to go into an infinite error loop on Github issue reports and certain other Github pages, presumably due to changes in code on their end. Unfortunately we use Github heavily for the wiki and issues tracker, so this is a major problem. The temporary workaround is, of course, a hack to relax JavaScript syntax even further. This hack is disgusting and breaks a lot of tests but is simple and does seem to work, so if I can't come up with something better it will be in FPR17. Most regular users won't be affected by this.

  • Colaboratory + Drive + Github -> the workflow made simpler
  • New project: Nice Telescope Planner

    And now, for something different, I have just dived into Java. I am sharing with you the first (pre-)release of Nice Telescope Planner, a simple cross-platform desktop utility for amateur astronomy hobbyists, written in Java. The aim is to provide an easy to use tool to help planning sky observation sessions, suggesting some of the interesting objects you may be able to watch at naked eye, or using amateur equipment (binoculars or small to medium size telescopes) in a given date/time and place.

  • Pete Zaitcev: Samsung shutting down CPU development in Austin

    An acquaintance of mine was laid off from Samsung. He was a rank-and-file ASIC designer and worked on FPU unit for Samsung's new CPU. Another acquaintance, a project manager in the silicon field, relayed that supposedly ARM developed a new CPUs that are so great, that all competitors gave up and folded their CPU development, resulting in the layoffs. The online sources have details.

  • Remove ^M (CTRL-M) Characters from a File in Linux - Putorius

    Operating systems have different ways to handle a newline in their text editors. For example Windows uses a specific carriage return (CR) which is depicted as ^M on Linux, followed by a line feed (LF) to indicate a newline. Linux and UNIX on the other hand use only the line feed to denote the end of a line. This often causes issues when transferring (or even copy and pasting) a file from Windows to Linux. It is hard to spot, and often leaves people scratching their head and wondering why their configuration file is not working.

  • When you need the numbers just right – benchmark and profiling applications in the Snap Store | Ubuntu

    The world of software is a vast and complex one, often too difficult to easily assess by human intuition alone. Which is why detailed and accurate measurements of software behavior are essential in helping us understand and gauge how well our applications perform. The Snap Store has a fair share of productivity tools and utilities, including a wide range of benchmarking and profiling tools. These are designed to help developers, system administrators and hardcore enthusiasts get a precise sense of their software, whether as part of research and design or for troubleshooting ongoing problems in production environments. Let’s have a little tour.

  • Ubuntu Fridge | Ubuntu Technical Board Call For Nominations

    The Ubuntu Technical Board is responsible for the technical direction of Ubuntu. It makes decisions on package selection, packaging policy, installation systems and processes, kernel, X server, display management, library versions, and dependencies. The board works with relevant teams to establish a consensus on the right path to take, especially where diverse elements of Ubuntu cannot find consensus on shared components. The current Technical Board is expiring at the end of the year, and the Community Council would like to confirm a new Technical Board, consisting of five people, who will serve for two years.
