Have you come across situations where your build tools suddenly stop working after you update the operating system? Do you want a simple way of setting up your build environment each time you change or format your machine?

One option is to use Docker-based build environments. In this approach, you can create Docker images with the necessary build tools and dependencies. However, you will still have to remember the tags, mount your source code manually, and execute Docker commands with multiple arguments each time. This approach is right but needs some effort.

If you were paying close attention to your IT department around the 8th of December, you might have heard some quiet sobbing and the occasional wail of, “Why? Why?! WHY?!” Now, it was the year 2020, so this might have seemed normal to you, but it’s actually something of a problem that could affect your business: CentOS is pretty much dead.

For the non-total-nerds among us, here’s the skinny: CentOS is a Linux-based operating system, typically used on servers. CentOS has been incredibly popular, and quite a few businesses run on it. But now, that’s changing.

CentOS is a Linux-based operating system, typically used on servers…But now, that’s changing

CentOS used to be released in thoroughly tested versions, the latest being CentOS 8. CentOS 8 was released in September of 2019 and was supposed to be supported for ten years. Now, it’s been decided that CentOS will no longer have versioned releases, opting for a rolling-release style of updates. That means there’ll be one version that constantly gets new software.

That’s cool in theory, but it means the operating system will be less stable overall. Essentially, it’s going to be used as a development branch of / testing ground for Red Hat Enterprise Linux and is no longer its own OS. If you have CentOS-based servers, you should migrate to another OS sooner rather than later.

And I just got my own CentOS-based VPS set up the way I wanted it.

Wait, What Does Red Hat Have To Do With This?

Here’s the short, short version of the history of CentOS: Red Hat (an OS developer) has two Linux distributions of its own and has had for a long time. There’s the free and community-focused Fedora and the business-focused highly expensive Red Hat Enterprise Linux (AKA RHEL).

Funny story: RHEL, despite its expensive licenses, is still mostly made from open source code, which anyone can access and use. And it’s a good OS, particularly for people who like stability.

In 2004, some smart people took all the open-source parts of RHEL and made a brand new, nearly identical operating system with it: the Community Enterprise Operating System, or CentOS. Basically, people could download and use an enterprise-level server OS for free. All the documentation for RHEL was compatible, and you could get support from the community.

It was the perfect alternative for anyone who didn’t have the budget for expensive software licenses.

In 2014, Red Hat offered to partner with the CentOS community. The idea was basically this: “It’s pretty much the same software. If our company and your community work together, both our products will be better! We make our money from enterprise customers, anyway.”

Most importantly, with Red Hat doing a lot of the heavy lifting in terms of updates and support, the CentOS community could focus on growing in other ways.

Red Hat pinky swore [citation needed] that they were in this for the long haul, and CentOS did continue to flourish. You know, until 2020.

Well, So Much For Pinky Swearing

Red Hat must have eventually decided that having a popular free version of its own enterprise software and managing it themselves no less — wasn’t that good for business. So they all but shut the project down.

Well, technically, they just changed how it operated. Instead of producing tested, production-ready versions, CentOS is merely a testing ground for RHEL. It is no longer, in my opinion, a good option for anyone who wants to run a stable server.

Current and Future CentOS Alternatives

So if you jumped on the CentOS 8 bandwagon, what should you put on your physical and virtual servers now? Well, you’ve got options.

Debian / Ubuntu

For those who don’t mind going to a very different kind of Linux, Debian has been the picture of OS stability and sysadmin-friendliness for a long time. If you want more frequent software updates, the Debian-based Ubuntu Server is popular and pretty good.

Oracle Linux

Yes, that Oracle has a RHEL-compatible Linux distribution of its own. But it’s not a clone, exactly. I mean, this is Oracle. It’s set up to use their tools and ecosystem, so I hope you like Oracle products. But hey, the OS itself is free!

ClearOS

ClearOS is another RHEL-compatible OS that’s mostly doing its own thing, though I’m not entirely sure what that thing is. Does the company have some deal with Hewlett-Packard? Anyway, they do have a free community edition and paid editions for home and business use.

The CloudLinux RHEL Fork

This is an upcoming release from the makers of CloudLinuxOS. It looks like they intend to load the new RHEL-based OS with some of their own tools, such as reboot-less server update tech. The first release is intended to be a more or less drop-in replacement for CentOS 8.

Rocky Linux

So the community that made and loved CentOS in the first place is, to say the least, ticked. They are so ticked that Greg Kurtzer (a co-founder of CentOS) has decided to do it all over again by making Rocky Linux and keep it in the community this time.

Again, the goal is to make a re-build of RHEL, a drop-in replacement for CentOS (at least for now). Eventually, the goal is to migrate from CentOS to Rocky Linux as easy as using a single, one-line command. The ETA for initial release isn’t quite set in stone, but I can personally vouch for how hard the community is working.

[See, full disclosure here… after writing this article, I joined the Rocky Linux documentation team.]

So Yeah, You Have Options

Some are out now, and others will be soon. Again, CentOS 8 will be supported until the end of 2021. CentOS 7, weirdly, will be supported until June 2024.

Migration shouldn’t be too complicated. Still, a pain in the rear that we have to do this at all, though.

Applications used in the field of Big Data process huge amounts of information, and this often happens in real time. Naturally, such applications must be highly reliable so that no error in the code can interfere with data processing. To achieve high reliability, one needs to keep a wary eye on the code quality of projects developed for this area. The PVS-Studio static analyzer is one of the solutions to this problem. Today, the Apache Flink project developed by the Apache Software Foundation, one of the leaders in the Big Data software market, was chosen as a test subject for the analyzer.

So, what is Apache Flink? It is an open-source framework for distributed processing of large amounts of data. It was developed as an alternative to Hadoop MapReduce in 2010 at the Technical University of Berlin. The framework is based on the distributed execution engine for batch and streaming data processing applications. This engine is written in Java and Scala. Today, Apache Flink can be used in projects written using Java, Scala, Python, and even SQL.

The right typeface can make or break your website. As designers, we will always be naturally drawn towards the premium fonts such as Circular, DIN, or Maison Neue; Before you know it, your website is racking up a font bill larger than your hosting bill.

We’ve put together a list of open-source fonts that will rival your fancy fonts, and might even persuade you to switch them out. All the fonts listed here are completely open-source, which means they’re free to use on both personal and commercial projects.

Manrope

Manrope has sprung onto the font circuit in style, with a website better than most early startups. It’s a variable font, which means you have a flexible range of font weights to choose from in a single font file. Manrope is a personal favorite of mine, it has every ligature you could want, and is fully multi-lingual. It’s a lovely bit of everything as it states on the website: it is semi-condensed, semi-rounded, semi-geometric, semi-din, semi-grotesque.

Gidole

DIN – the font we all love, the font that looks great at every size, and the font that costs quite a bit, especially with a large amount of traffic. Gidole is here to save the day, it’s an open-source version of our favorite – DIN. It’s extremely close to DIN, but designers with a keen eye will spot very few minor differences. Overall, if you’re looking to use DIN, try Gidole out before going live. (There is also a very passionate community around the font on Github)

Inter

Inter is now extremely popular, but we wanted to include it as it’s become a staple in the open-source font world — excellent releases, constant updates, and great communication. If you’re looking for something a bit fancier than Helvetica and something more stable than San Francisco, then Inter is a great choice. The font has now even landed on Google Fonts, making it even easier to install. As of today: 2500+ Glyphs, Multilingual, 18 Styles, and 33 Features… do we need to say more?

Overpass

Overpass was created by Delvefonts and sponsored by Redhat, it was designed to be an alternative to the popular fonts Interstate and Highway Gothic. It’s recently cropped up on large ecommerce sites and is growing in popularity due to its large style set and ligature library. Did we mention it also has a monospace version? Overpass is available via Google Fonts, KeyCDN, and Font Library.

Public Sans

Public Sans is a project of the United States Government, it’s used widely on their own department websites and is part of their design system. The font is based on the popular open-source font Libre Franklin. Public Sans has great qualities such as multilingual support, a wide range of weights, and tabular figures. The font is also available in variable format but this is currently in the experimental phase of development.

Space Grotesk

Space Grotesk isn’t widely known yet, but this quirky font should be at the forefront of your mind if you’re looking for something “less boring” than good old Helvetica. Space Grotesk has all the goodies you can expect from a commercial font such as multiple stylistic sets, tabular figures, accented characters, and multilingual support.

Alice

Alice is a quirky serif font usually described as eclectic and quaint, old-fashioned — perfect if you’re looking to build a website that needs a bit of sophistication. Unfortunately, it only has one weight, but it is available on Google Fonts.

Urbanist

Urbanist is an open-source variable, geometric sans serif inspired by Modernist typography. Designed from elementary shapes, Urbanist carries intentional neutrality that grants its versatility across a variety of print and digital mediums. If you’re looking to replace the premium Sofia font, then Urbanist is your best bet.

Evolventa

Evolventa is a Cyrillic extension of the open-source URW Gothic L font family. It has a familiar geometric sans-serif design and includes four faces. Evolventa is a small font family, generally used across the web for headlines and bold titles.

Fira Sans

Fira Sans is a huge open source project, brought to you, and opened sourced by the same team that makes Firefox. It’s Firefox’s default browser font and the font they use on their website. The font is optimized for legibility on screens. (And it’s on Google Fonts!)

Hack

Building a development website, or need a great code font to style those pesky code-blocks? Then Hack is the font for you. Super lightweight and numerous symbols and ligatures. The whole font was designed for source code and even has a handy Windows installer.

IBM Plex

IBM needs no introduction. Plex is IBM’s default website font and is widely used around the web in its numerous formats Mono, Sans, Serif, Sans-Serif, and Condensed – it has everything you’d need from a full font-family. The whole font family is multi-lingual, perfect for multi-national website designs. (It’s fully open-source!)

Monoid

Another great coding font, Monoid is a favorite of mine for anything code. The clever thing about Monoid is that it has font-awesome built into it, which they call Monoisome. This means when writing code, you can pop a few icons in there easily. Monoid looks just as great when you’re after highly readable website body text.

Object Sans

Object Sans (formally known as Objectivity) is a beautiful geometric font family that can be used in place of quite a few premium fonts out there. The font brings together the top qualities of both Swiss neo-grotesks and geometric fonts. The font works beautifully as large headings but can be used for body content as well.

Lunchtype

Lunchtype has a very interesting back-story, originally designed during the creator’s daily lunchtime during a 100-day project. If you’re looking for something a bit “jazzier” than the typical Helvetica for your project, then Lunchtype is a perfect choice. The family comes with numerous weights as well as a condensed version — enough to fill any lunchbox.

Jost

Inspired by the early 1920’s German sans-serif’s, Jost is a firm favorite in the open-source font world. Jost brings a twist to its closest web designer favorite Futura. When you want a change from the typical Futura, then Jost is a great option with its variable weighting as well as multilingual support.

Work Sans

Work Sans is a beautiful grotesk sans with numerous little eccentricities that may delight or annoy some designers. The font has variable weighting, multilingual support and is optimized for on-screen text use but works perfectly well for print also.
