Console-bound systemd services, the right way

Filed under
Gentoo

Let’s say that you need to run on your system some sort server software which instead of daemonising, has a command console permanently attached to standard input. Let us also say that said console is the only way for the administrator to interact with the service, including requesting its orderly shutdown – whoever has written it has not implemented any sort of signal handling so sending SIGTERM to the service process causes it to simply drop dead, potentially losing data in the process. And finally, let us say that the server in question is proprietary software so it isn’t really possible for you to fix any of the above in the source code (yes, I am talking about a specific piece of software – which by the way is very much alive and kicking as of late 2020). What do you do?

According to the collective wisdom of World Wide Web, the answer to this question is “use a terminal multiplexer like tmux or screen“, or at the very least a stripped-down variant of same such as dtach. OK, that sort of works – what if you want to run it as a proper system-managed service under e.g. OpenRC? The answer of the Stack Exchange crowd: have your init script invoke the terminal multiplexer. Oooooookay, how about under systemd, which actually prefers services it manages not to daemonise by itself? Nope, still “use a terminal multiplexer”.

Portage 3.0 stabilized

Filed under
Gentoo

We have good news! Gentoo’s Portage project has recently stabilized version 3.0 of the package manager.

What’s new? Well, this third version of Portage removes support for Python 2.7, which has been an ongoing effort across the main Gentoo repository by Gentoo’s Python project during the 2020 year (see this blog post).

In addition, due to a user provided patch, updating to the latest version of Portage can vastly speed up dependency calculations by around 50-60%. We love to see our community engaging in our software! For more details, see this Reddit post from the community member who provided the patch. Stay healthy and keep cooking with Gentoo!

Is an umbrella organization a good choice for Gentoo?

Filed under
Gentoo

The talk of joining an umbrella organization and disbanding the Gentoo Foundation (GF) has been recurring over the last years. To the best of my knowledge, even some unofficial talks have been had earlier. However, so far our major obstacle for joining one was the bad standing of the Gentoo Foundation with the IRS. Now that that is hopefully out of the way, we can start actively working towards it.

But why would we want to join an umbrella in the first place? Isn’t having our own dedicated Foundation better? I believe that an umbrella is better for three reasons:

1. Long-term sustainability. A dedicated professional entity that supports multiple projects has better chances than a small body run by volunteers from the developer community.
2. Cost efficiency. Less money spent on organizational support, more money for what really matters to Gentoo.
3. Added value. Umbrellas can offer us services and status that we currently haven’t been able to achieve.

I’ll expand on all three points.

The 10 Best Gentoo Linux Derivatives To Explore in 2020

Filed under
Linux
Gentoo

Gentoo Linux derivatives can be the ideal choice for the professional Linux users who don’t want to compromise about the system stability and performance. Some of you might know nothing about Gentoo Linux. Unlike other Linux distributions like Ubuntu, Kali, etc., Gentoo is quite unfamiliar...

Only the veteran Linux users know about this. And, the people who know about its potential hardly go back to any other distributions. The exclusivity of the Gentoo Linux is that you need to build the whole flashable image from the source code. That sometimes may require a few days based on your machine’s strength.

Gentoo: 200th Gentoo Council Meets and TheMightyBuzzard Adopts Gentoo

Filed under
Gentoo
  • 200th Gentoo Council meeting

    Way back in 2005, the reorganization of Gentoo led to the formation of the Gentoo Council, a steering body elected annually by the Gentoo developers. Forward 15 years, and today we had our 200th meeting! (No earth shaking decisions were taken today though.) The logs and summaries of all meetings can be read online on the archive page.

  • Site Potpourri for Mother's Day [Updated]

    Servers, Part 1. Behind the scenes, TheMightyBuzzard spent the weekend setting up a new server, aluminum. We are gradually moving to a Gentoo Linux base for our servers. Rather than pre-compiled binaries that get downloaded and run locally, Gentoo provides source code for download that one compiles and builds locally. At the moment we have three Gentoo-based servers (lithium, magnesium, and aluminum), one server on CentOS (beryllium), and the rest are on Ubuntu. By moving to Gentoo Linux, we get a streamlined server with a smaller attack surface as only the things we need are built into the kernel. That lone CentOS server? It has been with us from the start and has been no end of a hassle. Several services "live" on it and these need to be migrated before we can retire it. The first stage of that process is underway as Deucalion has been working on bringing up IRC on aluminum. In turn, other services will be brought over. Then we can (finally!) retire beryllium for good! Next on the list are sodium and boron (aiming to have completed by June.) Along with that, there have been new (security and otherwise) releases of other services that site depends on. We intend to get those upgraded as we move to an entirely Gentoo platform. Please join me in wishing them well on the migrations and upgrades!

  • Linux Fu: VPN For Free With SSH | Hackaday

    If you see a lot of banner ads on certain websites, you know that without a Virtual Private Network (VPN), hackers will quickly ravage your computer and burn down your house. Well, that seems to be what they imply. In reality, though, there are two main reasons you might want a VPN connection. You can pay for a service, of course, but if you have ssh access to a computer somewhere on the public Internet, you can set up your own VPN service for no additional cost. The basic idea is that you connect to a remote computer on another network and it makes it look like all your network traffic is local to that network. The first case for this is to sidestep or enhance security. For example, you might want to print to a network printer without exposing that printer to the public Internet. While you are at the coffee shop you can VPN to your network and print just like you were a meter away from the printer at your desk. Your traffic on the shop’s WiFi will also be encrypted.

  • YANUB: yet another (nearly) useless blog: QSoas tips and tricks: using meta-data, first level

    By essence, QSoas works with \(y = f(x)\) datasets. However, in practice, when working with experimental data (or data generated from simulations), one has often more than one experimental parameter (\(x\)). For instance, one could record series of spectra (\(A = f(\lambda)\)) for different pH values, so that the absorbance is in fact a function of both the pH and \(\lambda\). QSoas has different ways to deal with such situations, and we'll describe one today, using meta-data. [...] QSoas is a powerful open source data analysis program that focuses on flexibility and powerful fitting capacities. It is released under the GNU General Public License. It is described in Fourmond, Anal. Chem., 2016, 88 (10), pp 5050–5052. Current version is 2.2. You can download its source code there (or clone from the GitHub repository) and compile it yourself, or buy precompiled versions for MacOS and Windows there.

  • "Anarch", a new, public-domain Doom-like game coded from scratch in <256K

    I've argued that the video-game "Doom" is a sort of cultural version of Turing Completeness. Given that we're jamming computers and screens into just about any device these days, inevitably (and delightfully) someone gets it to run Doom: Watches, digital cameras, ATMs, pregnancy sticks. But you know what's even cooler? Creating your own new, original game in the exactly style of Doom, and making it so wildly resource-efficient that it fits in under 256K and will run on just about any computational device around. That's what the programmer Miloslav Číž has done, with his new game "Anarch". You can play it in your browser here or download it here; I just blasted away in it for a while, and it's a hoot — he neatly channels the mechanics and twitchy low-rez aesthetics of the original. Gameplay trailer is here; he put it in the public domain, and the code is all here on Gitlab.

Moving into the future with the FSF tech team

The FSF is well-known for spearheading the advocacy and support of free software, not just by recommending it in the face of pervasive proprietary options, but also by condemning nonfree software altogether. Following this recommendation is hard, even for us, because of the ever-increasing dependency on software and computer networks that we are all subject to. To follow through with our commitment, our tech team maintains a large list of services that many other offices our size would have long ago been wrongly pressured into transferring to one of the handful of gigantic corporations that monopolize those services. Your work email account is most likely implemented through Gmail or Outlook; your office's software is likely to be served by Amazon Web Services, along with all the data backups; your company's customer service is likely to be managed through Salesforce or SAP, and so on. Make no mistake, this is true for your local government and school networks, too! In contrast, at the FSF, we never jumped on the outsourcing wagon, and we don't use any Service as a Software Substitute (SaaSS) in our operations. We run our own email servers, telephony and fax service, print shop, full server stack, backups, networking, systems monitoring, accounting, customer relationship management (CRM) software, and a long list of other tasks and software development projects, with a team of just four extremely dedicated technicians. And we implement this on hardware that has been carefully evaluated to meet very high ethical standards, criteria that we push for vendors to achieve through our "Respects Your Freedom" certification program.
