The future of Python and when not to use a regex

Filed under
  • The future of Python: Concurrency devoured, Node.js next on menu

    The PyBay 2017 conference, held in San Francisco over the weekend, began with a keynote about concurrency.

    Though hardly a draw for a general interest audience, the topic – an examination of multithreaded and multiprocess programming techniques – turns out to be central to the future of Python.

    Since 2008, the Python community has tried to reconcile incompatibility between Python 2 and newly introduced Python 3.

    For years, adoption of Python 3 was slow and some even dared to suggest Python didn't have a future. As late as last year, Zed Shaw, an accomplished developer and author of the popular Learn Python the Hard Way, even ventured to opine, "There is a high probability that Python 3 is such a failure it will kill Python."

    Despite these unsubstantiated odds, Shaw – a polarizing figure for some Pythonistas – this year released a version of his book for Python 3.

  • When not to use a regex


    A regex is useful for validating simple patterns and for finding patterns in text. For anything beyond that it’s almost certainly a terrible choice.

Linux: Cloud Foundry, HMM, AMD Radeon and NVIDIA

  • Navigating Cloud Foundry

    This open source platform-as-a-service cloud platform bridges the gap between legacy applications and cloud services.

    For all the talk about the cloud, many applications continue to run on traditional servers. Hybrid architectures are sometimes the right option, but if you want to move corporate applications onto the Internet, you don’t want to start from scratch. Cloud Foundry, a platform-as-a-service (PaaS) cloud platform, enables enterprises to move older software to the cloud and build new cloud-centric programs using familiar tools and programming languages.

  • HMM Revised Its 25th Time, Seeking Inclusion In Linux 4.14

    Jerome Glisse of Red Hat has published his 25th revision to the Heterogeneous Memory Management (HMM) patch series. HMM is about allowing a process address space to be mirrored and for system memory to be transparently used by any device process.

    With HMM v25, there are more code comments and documentations, fixes to the code, merging the HMM-CDM patches into this patch series, and other improvements.

  • Radeon X.Org Driver Gets Fixed Up To Always Allow Page-Flipping With TearFree

    It's fairly rare these days seeing improvements to the xf86-video-ati DDX: the driver for those running a pre-AMDGPU (GCN 1.2) graphics card with this driver paired with Radeon DRM and not using the generic xf86-video-modesetting driver instead. But if you are using xf86-video-ati and use the "TearFree" feature to try to avoid screen tearing, a number of patches landed today.

    Michel Dänzer of AMD landed a handful of patches to the xf86-video-ati Git repository today for the Radeon DDX. Notably the patches make for always allowing DRI2 page-flipping to be used with TearFree and the same goes for DRI Present page-flipping with the TearFree option. Long story short, page-flipping should now always work in the TearFree mode.

  • NVIDIA Releases Vulkan 381.26.13 Beta Linux Driver

    NVIDIA's driver team has today released new Vulkan beta drivers for both Windows and Linux.

    The new NVIDIA Linux Vulkan beta is versioned at 381.26.13, so still not yet re-based to the current 384 series, but these changes should end up being merged for their next feature series to mainline.

In the past decade, adoption of open source software at the enterprise level has flourished, as more businesses discover the considerable advantages open source solutions hold over their proprietary counterparts, and as the enterprise mentality around open source continues to shift.

Enterprises looking to make smart use of open source software will find plenty of great reasons to do so. Here are just some of them.

Another Behind-the-Scenes Niche Where Open Source is Winning

Filed under

Do you spend a lot of time thinking about Bluetooth Low Energy (BLE) beacons? Unless you run a retail store, probably not. But if you do run a store (or stores) along with an e-commerce operation, BLE is a hot new thing you are either using already or thinking about using before long.

Why? Because the graffiti is on the wall, and it says, “Sales in physical stores are going down every year, and most retailers aren’t seeing enough online sales gains to take up the slack.” BLE may help stop the retail sales slide or at least slow it down. It’s cheap enough, especially with open source beacons, that it’s certainly worth a try.

SteamOS vs. Ubuntu vs. Windows 10: Which Is The Best Operating System For Gaming?

Filed under

Steam will continue to support Linux as we’ve seen on previous occasions, but other hardware companies should also lend a helping hand. This will include the likes of Intel, AMD, NVIDIA and others which control the driver stack.

If it took decades for Linux to improve heavily, then we should not ruin your expectations a tad bit because it will take several more years to further reduce that performance gap between Windows 10 and the latter. However, the fact that Linux is getting there should mean that Microsoft has something to worry.

Linux & Radio: What You Can Do With It Now

Filed under

Third, there is a belief that Linux apps are still too primitive to get anything productive done. Besides (whiny voice), “I tried Linux in 2005, and it was just too ha-r-r-d.”

Sorry. A lot of those objections are no longer valid. Linux is solid, stable, free for the most part and has become as easy to navigate as Windows. And those old apps are all grown up now.

You may have skipped over previous Linux articles we’ve run, but don’t skip this one. We’re not going to crow about Linux like it’s something brand new, because we both know it has been on your radar screen for 20+ years. This time, we’d rather you read about what you can do with it at your station — and primarily in your production studio — right now.

Dutch NCSC publishes PEF network data anonymising tool as open source

Filed under

The Dutch National Cyber Security Centre (NCSC) has published its Privacy Enhanced Filter (PEF) as open source software. The PEF tool is a research prototype that removes privacy-sensitive information from captured internet traffic as much as possible, allowing for threat detection and prevention without compromising privacy. It was developed in collaboration with the Netherlands Forensic Institute (NFI) and the NCTV (National Coordinator for Security and Counterterrorism) Safety Through Innovation Program.

  • For Fun and Profit: A New Book on the History of Linux and Open Source

    Sure, you can explain Linux’s popularity today in terms of factors that exist in the present — its technical features, the dynamism of the open source community, the corporate backing that Linux enjoys today, and so on.

    But, to understand what really launched Linux into the position it enjoys today, however, you need to know the history of Linux — as well as the history of the larger free and open source software universe.

  • Solus 3 released
  • Happy 24th Birthday, Debian!

    Today, August 16, 2017, Debian, the universal, Unix-like computer operating system powered by the Linux kernel turns 24 years of existence since the late Ian Murdock first announced the Debian Project back in 1993.

    Since then, the Debian Project decided to set the day of August 16 as the Debian Day, to celebrate the project's anniversary each year with organized social gatherings in various parts of the world.
