  • PostgreSQL: Psycopg 2.9 released

    Psycopg 2.9 has been released!

    This is a relatively small release compared to previous major releases. However the creation of the packages took a lot of effort. The previously used CI system now has reduced support for free software projects - it was decided that package building should be moved to GitHub Actions.

    Packaging has also become more complex because of the evolution of the Python packaging standards and the need to support multiple architectures (Intel, ARM, PPC...).

    Maintaining a project such as Psycopg requires a lot of effort. For this reason, we are extremely grateful to all our sponsors who are enabling the maintenance and development of Psycopg. Thank you very much!

  • Cutting Slack: When open source and team chat tools collide

    Founded in 2011, Mattermost targets enterprises with various self-managed and hosted software-as-a-service (SaaS) options. The Palo Alto, California-based company has raised around $70 million since its inception and claims some major customers, including Samsung, SAP, Deloitte, Nasdaq, and BNP Paribas, with a typical “large enterprise deployment” of between 10,000 and 40,000 users.

    Mattermost offers various plans covering most potential use cases, including its foundational free and open source Mattermost Team edition. It also has a commercial self-managed free edition called Mattermost Enterprise Edition EO, which provides the added ability to upgrade to more feature-rich paid versions. And if a customer on a hosted enterprise plan is concerned about their data becoming locked into commercial software, they can “downgrade” to the open source Mattermost Team edition without losing any data.

  • Notepad++ 8.1

    Notepad++ is a free (as in "free speech" and also as in "free beer") source code editor and Notepad replacement that supports several languages. Running in the MS Windows environment, its use is governed by GPL License.

  • What is open source?

    This is not to be confused with freeware, which is simply just software that does not come with a direct financial cost attached to it, but which likely won’t have any of the freedoms associated with open source software. Richard Stallman, founder of the Free Software Foundation, famously helped define what is meant by “free” in FOSS when he said:

    Free software is a matter of liberty, not price. To understand the concept, you should think of ‘free’ as in free speech, not as in free beer.

    To emphasize that the “free” denotes liberty rather than financial cost, the term FLOSS (“free/libre open source software”) is often used instead. But for all intents and purposes, FOSS and FLOSS mean the same thing.


    MySQL, for example, is an open source relational database management system that Oracle releases under a dual license — one a GNU General Public License (GPL), the other proprietary. The former affords most of the freedoms one would expect from FOSS, though the license is what is known as copyleft, which means that any derivative software must be issued under similar license terms. In other words, new software built from the open source software must be released under a similar open source license.

    Oracle’s secondary license is how it commercializes MySQL, selling it under the MySQL Enterprise Edition banner, which offers additional services not included in the GPL license, such as a fully managed database service; an enterprise-grade data backup service; a document store; and security smarts such as encryption and a firewall. Also, companies holding the commercial license are allowed to sell MySQL-based products without making the derivative product open source.

    In contrast to copyleft licenses such as GPL, so-called permissive software licenses such as the MIT License, GNU All-permissive License, and the Apache license don’t impose derivative software restrictions, making it easier for a private company to repurpose it as part of a proprietary product. In fact, they could also re-license their new software under a GPL license if they wish.

  • CTCFT Social Hour

    Hey everyone! At the CTCFT meeting this Monday (2021-06-21), we’re going to try a “social hour”. The idea is really simple: for the hour after the meeting, we will create breakout rooms in Zoom with different themes. You can join any breakout room you like and hangout.

    The themes for the breakout rooms will be based on suggestions. If you have an idea for a room you’d like to try, you can post it in a dedicated topic on the #ctcft Zulip stream. Or, if you see somebody else has posted an idea that you like, then add a emoji. We’ll create the final breakout list based on what we see there.

  • A white-knuckle ride of open COVID drug discovery

    Nearly 15 months ago, a large, fast-moving and unscheduled experiment began: probing a key protein of the coronavirus SARS-CoV-2 to find chemical starting points for drug discovery. The end point was to develop pills that people could take to treat COVID-19 and related diseases.

    This experiment pulled together a spontaneous, open, global, Twitter-fuelled collaboration called the COVID Moonshot. Urgency and a commitment to working openly recruited more than 150 active participants, spanning a huge range of expertise and technology across academia, biotechnology, pharmaceuticals and more, all working without claiming intellectual property. Open drug-discovery efforts are invariably super slow — ours has been an express train on tracks we have laid down as we go. It is a way of working that none of us realized was possible.

  • The development release Wine 6.11 is out now, pulls in patch to help Roblox work on Linux

    Another two weeks and another bottle of Wine has been opened. This Wine 6.11 development release pulls in an interesting patch too for Roblox.

    I doubt Roblox needs much of an introduction. Sadly it's another game that doesn't support Linux and stopped working in Wine long ago - until now. Wine bug #39142 (Roblox Client/Server connection is dropped with error "This server has shut down.") is now solved with this commit. So the Roblox client should now work but keep in mind there's a number of caveats, some of which can be seen here.

7 Free And Open Source Download Managers For Windows And Linux

Filed under

Download Managers are one of the great ways to boost and manage your downloads from the internet. However, settling on one best download manager could be challenging as there are tons of them out there. Hence, let’s look at some of the best, free, and open-source download managers for Windows and Linux.

IDM (Internet Download Manager) is considered one of the most popular download managers, but it’s paid and isn’t available for Linux. You can also take the Download Managers in this list as IDM alternatives. Mind you, the order in which the apps are listed has nothing to do with how good an app is. If you are also looking for the best DMs for Android, check out our best download managers for Android list.


The UI is simple, clean, and highly customizable. One of the app’s differentiating features is that it acts as a front-end for one of the popular command-line software Youtube-dl. Downloading videos from YouTube was a breeze, but it also works for DailyMotion and Vimeo. These features, combined with the download speed and open-source nature, make it one of the best IDM alternatives and best download managers.

To install the Persepolis download manager, head over to the official website to install instructions for Windows, Mac, and Linux.

2. Motrix

Another completely free software that works like a charm. Motrix is an open-source download manager that looks great UI-wise and also offers great features. We tested it out and found that it takes time to initialize the download, but once it starts downloading, the speed is better than a browser.

5 Best htop alternatives to monitor Linux systems

Filed under

Htop is a process manager that allows us to see the processes in execution and the usage of system resources using the Linux terminal. With its text-based interface that supports the mouse, we can easily operate it and perform various functions such as it is very easy to kill any process on htop. In short, it has all functions we required to monitor and manage system processes using the command terminal. Further, easy to understand due to the simple fields of CPU, Mem, PID, and Command when opening htop.

At the top of htop, the usage rate of each CPU will be listed. It is worth noting that the number of logical cores of the CPU is displayed there. However, htop is no the only way on Linux to monitor process and hardware resources there are other good options as well. Thus, that’s why we decided to come with some good htop alternative tools in this list.

7 Best Free and Open Source HTML Editors

Filed under

An HTML editor is computer software for creating web pages. As this type of editor helps to remove the frustration out of creating web pages, it represents an indispensable tool for graphic and web designers. Specialized HTML editors provide convenience and added functionality.

There are three main types of HTML editors. The most common type is the WYSIWYG HTML editor. Here the editor provides an editing interface which resembles how the page will be displayed in a web browser. This is achieved by embedding a layout engine. For example, in the case of BlueGriffon, the layout engine that is used is Gecko, which is also used in the Firefox web browser. The other types of editor are text source editors and object editors.

  • Stuck Updates Fix

    When rolling out a new feature that lets you skip (offline) updates on boot-up earlier this week we have messed up and also brought in a nasty bug that prevents updates from applying. Unfortunately we can’t automatically rectify this problem because, well, updates are never applied. In case you find Discover showing the same updates over and over again, even after rebooting to apply the update, you may be affected.

  • How Russian threats in the 2000s turned this country into the go-to expert on cyber defense

    Estonia is no stranger to the cyber threat posed by Russia. Back in 2007, a decision to relocate a Soviet-era war memorial from central Tallinn to a military cemetery sparked a diplomatic spat with its neighbor and former overlord. There were protests and angry statements from Russian diplomats. And just as the removal works started, Estonia became the target of what was at the time the biggest cyberattack against a single country.

    The Estonian government called the incident an act of cyberwarfare and blamed Russia for it. Moscow has denied any involvement.

    The attack made Estonia realize that it needed to start treating cyber threats in the same way as physical attacks.

  • Linux Plumbers Conference: Tracing Microconference Accepted into 2021 Linux Plumbers Conference

    We are pleased to announce that the Tracing Microconference has been accepted into the 2021 Linux Plumbers Conference. Tracing in the Linux kernel is constantly improving. Tracing was officially added to Linux in 2008. Since then, more tooling has been constantly added to help out with visibility. The work is still ongoing, with Perf, ftrace, Lttng, and eBPF. User space tooling is expanding and as the kernel gets more complex, so does the need for facilitating seeing what is going on under the hood.
