  • Watch: Linus Torvalds Has His Name Written on a T-33 Fighter Jet Aircraft

    We reported a few days ago on a very interesting and awesome fact about the creator of the Linux kernel, Mr. Linus Torvalds, who apparently loves to go Zero-G in a T-33 fighter jet aircraft to relax in between kernel pulls, besides scuba diving.

  • Linus Torvalds Announces Linux Kernel 4.2 Release Candidate 3 with Updated Drivers

  • Make Music with these Sublime Open Source Tools

    Linux is an attractive platform for professional audio production. It is an extremely stable operating system that has good support for audio hardware. Using a Linux machine as the focus of your recording setup opens a world of possibilities for an affordable price.

    Software that creates music can often be expensive. The heavyweight Cubase, Apple LogicPro, FL Studio, Adobe Audition, and Sony ACID Pro are all impressive software music production environments. Unfortunately, they cost hundreds of dollars and are released under a proprietary software license. Fortunately, there is a good range of open source software that lets you produce professional quality recordings.

  • Fiber: Yet Another Web Browser For Qt/KDE

    Ken was even experimenting with ways for Fiber to potentially remove the address bar from his browser, but those experiments haven't panned out and instead will be complemented by many browser extensions. The design of Fiber are many extensions: everything down to basic navigational elements and bookmark handling will be through extensions.

  • Fedora Hubs and possible communication improvement suggestion

    Mostly Fedora has a plenty amazing services, but right now we suffering from a lack of integration to the desktop back and forth (between users – devs, and our infra and services between them) , and this doesn’t serving us well as I see. But Fedora .Next doesn’t stopped, it’s rolling like a thunder, and Mizmo Hub design can be our critical piece of the puzzle…

  • doas - dedicated openbsd application subexecutor

    Talking with deraadt and millert, however, I wasn’t quite alone. There were some concerns that sudo was too big, running too much code in a privileged process. And there was also pressure to enable even more options, because the feature set shipped in base wasn’t big enough. Hurray, tension. It wasn’t the problem I was trying to solve, but it was an opening from which to launch my diabolical plan.

Python Programming

  • Equality vs Identity

    You're probably already familiar with equality: that's the == operator. identity uses the is operator.

  • Creating a Binary Search in Python – Real Python

    Binary search is a classic algorithm in computer science. It often comes up in programming contests and technical interviews. Implementing binary search turns out to be a challenging task, even when you understand the concept. Unless you’re curious or have a specific assignment, you should always leverage existing libraries to do a binary search in Python or any other language.

  • How to Set Axis Range (xlim, ylim) in Matplotlib

    Matplotlib is one of the most widely used data visualization libraries in Python. Much of Matplotlib's popularity comes from its customization options - you can tweak just about any element from its hierarchy of objects. In this tutorial, we'll take a look at how to set the axis range (xlim, ylim) in Matplotlib, to truncate or expand the view to specific limits.

  • On code isolation in Python | Artem Golubin

    I started learning Python in 2009, and I had a pretty challenging task and somewhat unusual use of Python. I was working on a desktop application that used PyQT for GUI and Python as the main language. To hide the code, I embedded Python interpreter into a standalone Windows executable. There are a lot of solutions to do so (e.g. pyinstaller, pyexe), and they all work similarly. They compile your Python scripts to bytecode files and bundle them with an interpreter into an executable. Compiling scripts down to bytecode makes it harder for people with bad intentions to get the source code and crack or hack your software. Bytecode has to be extracted from the executable and decompiled. It can also produce obfuscated code that is much harder to understand.
