  • Fractal December'18 Hackfest (part 1)

    The Tuesday 11th started the second Fractal Hackfest. I've organized this hackfest in Seville, the city where I studied computer science and here I've a lot of friends in the University so is a good place to do it here.

    The weather was important too for the hackfest selection, in December Seville is a good choice because the weather is not too cold, we're having sunny days.

    The first day was a good day, thinking about some relevant issues and planning what we want to do. We talked about the work needed for the interface split, about the E2EE support, new features and the need for a new release.

    We're having some problems with the internet connection, because the University has a restricted network policy and we ask for the guess internet connection the Monday, but we're still waiting.

  • Unexpected fallout from /usr merge in Debian

    Back in 2011, Harald Hoyer and Kay Sievers came up with a proposal for Fedora to merge much of the operating system into /usr; former top-level directories, /bin, /lib, and /sbin, would then become symbolic links pointing into the corresponding subdirectories of /usr. Left out of the merge would be things like configuration files in /etc, data in /var, and user home directories. This change was aimed at features like atomic upgrades and easy snapshots. The switch to a merged /usr was successful for Fedora 17; many other distributions (Arch, OpenSUSE, Mageia, just to name a few) have followed suit. More recently, Debian has been working toward a merged /usr, but it ran into some surprising problems that are unique to the distribution.

    Debian and its derivatives are definitely late to the /usr merge party. Systems running Debian testing that were initially installed before June 2018 still have /bin, /sbin, and /lib as normal directories, not as symbolic links. The same applies to Ubuntu 18.10. But both Debian and Ubuntu want to make the switch to a merged /usr. Debian tried, but it hit something completely unexpected.

    The Debian /usr merge history started in 2016, when Marco d'Itri got the usrmerge package into Debian unstable. This package contains a Perl script that converts an existing system into the state with a merged /usr. Also, a change was made to the debootstrap program (which installs a Debian system into a chroot), so that it could create the needed symbolic links by itself before installing any packages. The end result is the same in both cases.

    [...]

    The Debian package sed also has /bin/sed, not /usr/bin/sed. In the bug report, the problem is treated like a one-off issue, to be solved by a rebuild. However, on the debian-devel mailing list, Ian Jackson quickly pointed out that the problem is, in fact, due to /usr merge on the build daemons. He suggested that the change should be reverted. Dirk Eddelbuettel seconded that suggestion, and noted that he expects "much more breakage to follow". Indeed, similar problems were triggered in sympow, pari, and monitoring-plugins. Other bugs of this nature can be found by searching the Debian bug tracking system for a special tag (but this search also finds other kinds of issues).

    [...]

    The discussion is still in progress, though; no consensus has been reached. A bug was filed against debootstrap by Jackson to revert the change to merge by default for the next release of Debian. Due to the disagreement of the debootstrap maintainer to the proposed change, Jackson reassigned the bug to the Debian Technical Committee, which is the ultimate authority for resolving otherwise unresolvable technical disputes within Debian. There is also a request from the Debian backports FTP master that the default should be the same in Debian stable backports and in Debian testing. Emilio Pozuelo Monfort, a member of the release team, also spoke in favor of reverting to non-merged /usr in new installations.

    It is impossible to predict now how the Technical Committee will rule. In the worst case for /usr-merge proponents, proper introduction of a merged /usr into Debian may be delayed by a few more years. But, if it votes for keeping the status quo, new end-user systems in the next stable release of Debian will have merged /usr, old but upgraded ones won't, and the build daemons will reliably build packages suitable for both cases, just like what's planned for Ubuntu 19.04. No flag day is needed in this scenario, so it would follow the best Debian traditions of not forcing transitions onto users.

  • How to use TOAD The Open Source Android Deodexer

    Deodexing Android can be a time-consuming process which involves pulling /system files from your Android device, deodexing them using PC tools, and installing them back on your phone. Not to mention that whenever Google releases a new Android version, the process for deodexing ROMs alters – which means tools for deodexing need to play catchup. Many deodexing tools have become defunct due to lack of update from the developers.

    A new tool called TOAD (The Open Source Android Deodexer) has been released, which aims to not only be incredibly easy, its open-source nature allows the development community to keep it updated with the latest deodexing methods. TOAD utilizes batch files for processing odexed files, so new batch files can easily be added or modified by the development community.

  • How Facebook Made a Universal Open Source Language for the Web

    THE CODE THAT runs the web is a melting pot of programming languages and technologies. JavaScript, the most popular language on the web, is the standard for writing code that runs in your browser. But the server side is much more diverse. Java (no relationship to JavaScript) remains popular, as do PHP, Python, and Ruby. Mobile app developers, meanwhile, have their own preferred languages, like Kotlin for writing Android apps or Apple's Swift for iOS.

  • 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.
