  • 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.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
