  • Best practices for guiding new coders

    As the new year progresses, many free and open source projects are turning their attention to various formalized mentoring programs, such as Mozilla's Winter of Security, Outreachy, and (the program with my favorite name) the X.Org Endless Vacation of Code. Patterned after the success of Google's Summer of Code, these programs give many new programmers a chance to gain firsthand experience working within successful FLOSS (Free/Libre Open Source Software) projects and the projects themselves access to fresh talent.

  • Developing an nrf51822 based embedded device with Qt Creator and Debian

    I'm currently developing an nRF51822-based embedded device. Being one the Qt/Qt Creator maintainers in Debian I would of course try to use it for the development. Turns out it works pretty good... with some caveats.

  • [Wine Staging] Release 2.2

    Since the last release, we tested various games with the CSMT (command stream multithreading) feature enabled to identify remaining bugs and possible ways to improve performance. As a result, this release includes various speed optimizations, especially for DX10/11 games. Some functions, for example updating subresources, which previously required synchronization with the command stream thread, can now be done asynchronously. There might still be differences compared to Wine Staging 2.0, since some of the speed improvements from the original CSMT patchset contained bugs and have not been fixed / added back yet.

  • Wine-Staging 2.2 released with CSMT speed optimizations

    The Wine team has put out another Wine-Staging release based on Wine 2.2, this new development release has some CSMT speed optimizations.

    For those that don't know what CSMT is, it stands for "Commandstream multithreading" which should give you better performance in Wine.

  • Wine-Staging 2.2 Offers CSMT Speed Optimizations

    Wine-Staging 2.2 is now available as the latest version of Wine that carries various testing/experimental patches re-based atop the latest Wine bi-weekly development snapshot.

  • Destinations & Dota VR Hub are now available on Linux

    Valve have already put up Linux versions of both Destinations and The Dota VR Hub now that SteamVR is supported on Linux in beta.

  • Valve debuts developer build of SteamVR for Linux

    Heads up, Linux fans who are maybe also VR developers (or vice versa): The folks at Valve Software have today released a very much still-in-development version of SteamVR that runs on Linux.

  • Valve launches SteamVR support for Linux

    Valve has been giving Steam users Linux love since 2012, and it's not stopping with VR. The company just launched SteamVR for Linux, letting developers create Linux content for the HTC Vive VR headset, trackers and other hardware. The program is in beta, meaning developers must use an NVIDIA developer beta driver that's built on "Vulkan," the successor to OpenGL. You're limited to "direct" mode, meaning you can only display images on the headset and not a desktop display at the same time.

  • Valve Finally Brings SteamVR To Linux As A Developer Release

    It was over four months ago now that Valve showed SteamVR running in Linux for the first time. Today, it’s finally launching the platform on the operating system, albeit in a limited form.

    SteamVR comes to Linux as a development release, meaning it’s intended for content creators to start working on apps for the open-source OS, and not for regular Linux users to access. To that end, users must have opted into the public Beta for Steam or SteamVR to access it along with obtaining pre-release drivers. On Nvidia cards that means the 375.27.10 “Developer Beta Driver”, while AMD users will need a pre-release version of the radv driver. You’ll also need Unity 5.6 to actually create content through Linux.

LG Watch Sport review: Not the watch Android Wear needs right now

Filed under
Android
Reviews

The LG Watch Sport just looks and feels like a “gadget” and not a “watch.” It harkens back to the days of those old Microsoft Spot watches (remember those?). Instead of reaching as broad a market as possible with the first full-featured Android Wear 2.0 watch, LG and Google have given us something with almost impossibly narrow appeal. This watch is almost exclusively for large-wristed athletic types whose fashion sense leans toward calculator watches. I found myself wanting to put it on just before I left for the gym, and itching to take it off the moment I got home.

Android Wear 2.0 deserves a better showcase watch than this. With any luck, another manufacturer will step in with a more universally acceptable design that at least supports Android Pay and has a heart-rate monitor.

    GRUB, it is time we broke up. It’s not you, it’s me. Okay, it’s you. The last 15+ years have some great (read: painful) memories. But it is time to call it quits.

    Red Hat Linux (not RHEL) deprecated LILO for version 9 (PDF; hat tip: Spot). This means that Fedora has used GRUB as its bootloader since the very first release: Fedora Core 1.

    GRUB was designed for a world where bootloaders had to locate a Linux kernel on a filesystem. This meant it needed support for all the filesystems anyone might conceivably use. It was also built for a world where dual-booting meant having a bootloader implemented menu to choose between operating systems.

Google's Upspin Debuts

OSS
  • Another option for file sharing

    Existing mechanisms for file sharing are so fragmented that people waste time on multi-step copying and repackaging. With the new project Upspin, we aim to improve the situation by providing a global name space to name all your files. Given an Upspin name, a file can be shared securely, copied efficiently without "download" and "upload", and accessed by anyone with permission from anywhere with a network connection.

  • Google Developing "Upspin" Framework For Naming/Sharing Files

    Google today announced an experimental project called Upspin that's aiming for next-generation file-sharing in a secure manner.

  • Google releases open source file sharing project 'Upspin' on GitHub

    Believe it or not, in 2017, file-sharing between individuals is not a particularly easy affair. Quite frankly, I had a better experience more than a decade ago sending things to friends and family using AOL Instant Messenger. Nowadays, everything is so fragmented, that it can be hard to share.

    Today, Google unveils yet another way to share files. Called "Upspin," the open source project aims to make sharing easier for home users. With that said, the project does not seem particularly easy to set up or maintain. For example, it uses Unix-like directories and email addresses for permissions. While it may make sense to Google engineers, I am dubious that it will ever be widely used.

  • Google devs try to create new global namespace

    Wouldn't it be nice if there was a universal and consistent way to give names to files stored on the Internet, so they were easy to find? A universal resource locator, if you like?

    The problem is that URLs have been clunkified, so Upspin, an experimental project from some Google engineers, offers an easier model: identifying files to users and paths, and letting the creator set access privileges.

The Year Of Linux On Everything But The Desktop

Linux
Microsoft

The War on Linux goes back to Bill Gates, then CEO of Microsoft, in an “open letter to hobbyists” published in a newsletter in 1976. Even though Linux wouldn’t be born until 1991, Gates’ burgeoning software company – itself years away from releasing its first operating system – already felt the threat of open source software. We know Gates today as a kindly billionaire who’s joining us in the fight against everything from disease to income inequality, but there was a time when Gates was the bad guy of the computing world.

Microsoft released its Windows operating system in 1985. At the time, its main competition was Apple and Unix-like systems. BSD was the dominant open source Unix clone then – it marks its 40th birthday this year, in fact – and Microsoft fired barrages of legal challenges to BSD just like it eventually would against Linux. Meanwhile Apple sued Microsoft over its interface, in the infamous “Look and Feel” lawsuit, and Microsoft’s reign would forever be challenged. Eventually Microsoft would be tried in both the US and the UK for antitrust, which is a government regulation against corporate monopolies. Even though it lost both suits, Microsoft simply paid the fine out of its bottomless pockets and kept right at it.

  • Linux Digital Audio Workstation Roundup

    In the world of home studio recording, the digital audio workstation is one of the most important tools of the trade. Digital audio workstations are used to record audio and MIDI data into patterns or tracks. This information is then typically mixed down into songs or albums. In the Linux ecosystem, there is no shortage of Digital audio workstations to chose from. Whether you wish to create minimalist techno or full orchestral pieces, chances are there is an application that has you covered.

    In this article, we will take a brief look into several of these applications and discuss their strengths and weaknesses. I will try to provide a fair evaluation of the DAWs presented here but at the end of the day, I urge you to try a few of these applications and to form an opinion of your own.

  • Shotcut Video Editor Available As A Snap Package [Quick Update]

    Shotcut is a free, open source Qt5 video editor developed on the MLT Multimedia Framework (it's developed by the same author as MLT), available for Linux, Windows and Mac. Under the hood, Shotcut uses FFmpeg, so it supports many audio, video and image formats, along with screen, webcam and audio capture.

    The application doesn't require importing files, thanks to its native timeline editing. Other features worth mentioning are multitrack timeline with thumbnails and waveforms, 4k resolution support, video effects, as well as a flexible UI with dockable panels.

    Wayland 1.13.0 has entered development in the first days of the year, but the first Alpha build arrived at the end of January, along with the Alpha version of the Weston 2.0 compositor, including most of the new features that are present in this final release that you'll be able to install on your Linux-based operating systems in the coming days.

  • Weston 2.0 RC2 Wayland Compositor Arrives With Last Minute Fixes

    While Wayland 1.13 was released today, Bryce Harrington today opted against releasing the Weston 2.0 reference compositor and instead issue a second release candidate.

    Weston 2.0 is the next version of this "playground" for Wayland compositor technologies since the new output configuration API had broke the ABI, necessitating a break from the same versioning as Wayland.

  • Making Movies with QML

    One of the interesting things about working with Qt is seeing all the unexpected ways our users use the APIs we create. Last year I got a bug report requesting an API to set a custom frame rate for QML animations when using QQuickRenderControl. The reason was that the user was using QQuickRenderControl as an engine to render video output from Qt Quick, and if your target was say 24 frames per second, the animations were not smooth because of how the default animation driver behaves. So inspired by this use case I decided to take a stab at creating such an example myself.

Will Smith from Flint Innovations Limited is informing Softpedia today about their up and coming Linux-based operating system for PCs and Raspberry Pi devices, Flint OS, based on the open-source Chromium OS project.

These days, we see more and more developers and entrepreneurs launching new operating systems based on Chromium OS, which Google uses with much success for its Chrome OS on many Chromebooks that you can purchase today. But Flint OS is somehow a bit special, not only because it provides support for both Raspberry Pi SBCs and x86 computers with either Intel or Nvidia GPUs, but because it uses Android apps.

All in all I'm quite happy with slackware 14.2 on my quasi-modern computer. Old school linux and openbsd types will no doubt feel at home with slack. There's no systemd to worry about. A full install takes about 9 gigs of drive space. The slackware folks have obviously put a ton of work into this new release. A word of warning to linux newbies, this isn't the easiest distro to install and is probably best suited to linux intermediates or experts.

Ten Years as Desktop Linux User: My Open Source World, Then and Now

I've been a regular desktop Linux user for just about a decade now. What has changed in that time? Keep reading for a look back at all the ways that desktop Linux has become easier to use -- and those in which it has become more difficult -- over the past ten years. I installed Linux to my laptop for the first time in the summer of 2006. I started with SUSE, then moved onto Mandriva and finally settled on Fedora Core. By early 2007 I was using Fedora full time. There was no more Windows partition on my laptop. When I ran into problems or incompatibilities with Linux, my options were to sink or swim. There was no Windows to revert back to. Read more
