Humor

Debain is the only group of software developers who still believe that Richard Stallman invented programming. Everyone else now correctly credits Bill Gates for doing so.

Growing up in Keizer, Justin Gallardo and Michael Burns learned about computers by taking them apart to see how they worked and by doing triage when their machines crashed.

Now the 20-year-old computer science majors at Oregon State University are working to ensure that children in developing countries have that same opportunity.

Those of us who grew up in the seventies probably remember variations of this pejorative phrase. often aimed at either the schoolyard bully, or perhaps your best friend in jest.

“I don’t know what Linux is but I don’t like it”

Filed under
Linux

In college, almost everyone has a personal computer. More and more people are using Macs - it seems that 10% of the class of 2007 uses Macs, whereas it appears that roughly half of freshman (class of 2010) are using Macs. I’ve used PCs, Macs, and lately a lot of Linux. I’ve even written my own operating system.

Intel’s 5G-oriented Atom P5900 features up to 24 10nm Tremont cores

Like the C3000, the P5900 supports up to 128GB DDR4, now at up to 2933 MT/s. It similarly supports 16x PCIe 3.0, 16x SATA 3.0, 4x USB 3.0, and 4x USB 2.0 interfaces. However, the SATA links can now be reconfigured as up to 16x PCIe 2.0 or 16x USB 3.0, so you can now have up to 32x PCIe lanes. Other features include GPIO, 3x UARTs, and -40 to 85°C support. We saw no mention of OS support, but we imagine that like the Atom C3000, the Atom P5900 is primarily designed to run Linux. The C3000 has appeared on a variety of Linux-powered networking appliances such as Advantech’s FWA-1012VC, as well as numerous COM Express Type 7 modules like Avnet/MSC’s MSC C7B-DV. Earlier this month, it showed up on a Versalogic Grizzly SBC. Read more

    Valve's latest game, Dota Underlords, has today left Early Access and with it comes a huge patch full of new content and features. The biggest addition to the Underlords strategy game is the City Crawl campaign. A single-player mode, that explains a bit about what's going on. It seems "Mama Eeb" passed away, leaving a power vacuum in White Spire, with the four Underlords attempting to take control. City Crawl is where you do that, as you go through various different types of challenges and while doing so earn new outfits for the Underlords.

  • Linux Gaming: Overclock your Nvidia GPU on Linux with GreenWithEnvy

    Overclocking your Nvidia card on Linux used to be a nightmare. There was lots of different commands you had to type into the terminal, and there was no easy way to monitor your temperature and fan speeds.

Programming: AWK and Python

    An endearing feature of AWK is the flexibility of its syntax. Some other languages have very strict rules about how to write commands, and if you disobey the rules, you get error messages.

  • Easily Clip/Split Large Videos With this Python Script

    Sometimes you have may have a large video file, and you want to split that video into many smaller videos with start and end times that you specify yourself. And of course, you don’t want to do it manually with a video editor because it’s gonna take forever. What we are talking about for example, is when you have a video of 10 minutes, and you want to create 3 smaller clips out of it such that the first one is between 1:20 and 2:20 for example, and the second one is between 3:00 and 4:00 and the last one is between 7:10 and 8:15. Such things is theoretically hard, but not with Python and its amazing tools!

Linux (Kernel): Clear Linux, AMD Radeon Graphics and Raspberry Pi 4

  • One Of Clear Linux's Kernel Patches To Help With Boot Time Proposed For Upstreaming

    Besides Clear Linux delivering often leading x86_64 Linux performance at run-time, when it comes to boot performance it has also been at the forefront -- in some configurations, can boot in 300 ms. Intel has invested significantly in ensuring Clear Linux boots as fast as possible for when running in the cloud or on containers in order to respond to increased demand as quickly as possible as well as for use-cases like Clear Linux within automobiles where they need to get automobile cameras active within two seconds of power on. One of their many kernel patches could be on its way to the mainline kernel.

Linux 5.6 brings many new features As it concerns the AMDGPU kernel driver, there is reset support for Renoir and Navi, initial bring-up for AMD Pollock, HDCP 2.x support, the kernel bits for Vulkan timeline semaphore support, DP MST DSC compression, and other fixes and code improvements.

  • VC4 DRM Driver Gets Patched For BCM2711 / Raspberry Pi 4 Support

    While the Linux 5.5 kernel landed Broadcom BCM2711 SoC and Raspberry Pi 4 enablement, one of the loose ends has been getting the open-source "VC4" DRM driver wired up for the display hardware on this latest Raspberry Pi. Patches are now pending for VC4 DRM to provide that display support and could potentially see it mainlined for Linux 5.7.
