  • 15 ways to leave your cloud provider

    Avoid concentration

    While it’s tempting to keep things simple by using the same cloud for everything, the danger is that one cloud becomes a big point of failure. Microsoft, for instance, bought GitHub and this should give Azure users a reason to start thinking about storing their code in other repositories. Or at the very least, make sure it is pushed regularly to backups. The same goes for the other clouds.

    Use open source

    Proprietary code has many wonderful aspects. Sometimes the business model delivers some amazing software. There are many times in life when you get what you pay for and that can be true in the software world too. But only open source software offers you the freedom to move the code easily and quickly without begging, “Mother, may I?” Richard Stallman always said that he was after “free as in speech, not free as in beer.”

    Avoid proprietary tools

    The cloud providers usually offer two types of products: open source clones and proprietary tools. While the closed source products may offer plenty of tempting options and attractive innovations, the threat of losing service is too great to risk using them. If you choose the MySQL service at AWS, you can move to MySQL on your own box. If you choose a proprietary tool, you can’t.

  • Jan-Erik Rediger: Three-year Moziversary

    Has it really been 3 years? I guess it has. I joined Mozilla as a Firefox Telemetry Engineer in March 2018, I blogged twice already: 2019, 2020.

    And now it's 2021. 2020 was nothing like I thought it would and still been a lot like I said last year at this point. It's been Glean all over the year, but instead of working from the office and occasionally meeting my team in person, it's been working from home for 12 months now.

    In September of last year I officially became the Glean SDK tech lead and thus I'm now responsible for the technical direction and organisation of the whole project, but really this is a team effort. Throughout the year we made Project FOG happen. At least the code is there and we can start migrating now. It's far from finished of course.

  • Firefox 86 TOTALLY FIXES the cookie problem.

    Firefox 86 is the latest release of Firefox and it's got two killer features. One of them is how Firefox handles cross-origin requests and cookies: by silo-ing each web page. Now, when you visit a new site for the first time, any assets loaded from other websites (read: Google Analytics) don't have your login information from your Google Account. This is CRITICAL!

  • Community Member Monday: Rafael Lima

    I am a university professor in Brazil, and I teach and research optimization applied to management sciences. In my work I often need to write papers and prepare spreadsheets to analyze data, and for that I’ve been using LibreOffice for over a year now. I have been working with supply chain optimization problems such as vehicle routing, network design and facility location.

    I have always been an enthusiast of Open Source, since my undergraduate days in 2001. At the time I started using Linux and most of my current research work is done using FOSS tools. The dynamics of how open source software is developed is a topic that has always caught my attention.

    Outside of work, I like to spend my free time practicing sports (mostly playing tennis) and whenever I have the opportunity I like to travel to new places. And obviously, like many tech enthusiasts, I like gaming too!

  • Learning the Poke language in Y minutes

    Mohammad-Reza Nabipoor has written a nice short tutorial called "Learn
    the Poke Language in Y minutes". The tutorial has the form of a Poke
    program itself, and I think it really highlights the most uncommon
    (and useful!) features of our domain-specific language.

    The tutorial is also available as part the poke source distribution in
    `doc/learn-poke-language-in-y-minutes.pk' so you can play with it. Find
    the plain source file here.

    Mohammad will be improving and updating it as the language grows.
    Thanks Mohammad, and happy poking!

  • Swiss National Bank releases paper regarding CBDC and GNU Talers

    The Swiss National Bank has released a paper on the advantages of GNU Talers over blockchain and account-based digital money transactions for Central Bank Digital Currency.

    A possible technical implementation was presented in a paper by the Swiss National Bank (SNB), discussing the merits of token-based digital cash called GNU Talers. The Swiss Bank has been developing the concept of ‘Taxable Anonymous Libre Electronic Reserves’, or Taler for short. Interested parties have been able to try out the cryptographically secured digital ‘coins’ for some time.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
