Graphics/Benchmarks

This month Western Digital introduced the WD_BLACK SN850 as the latest PCI Express 4.0 solid-state drive hitting the market. The WD_BLACK SN850 is a surprisingly strong performer if looking to upgrade to PCIe 4.0 solid-state storage, competing with the fastest of the consumer drives currently available.

The WD_BLACK SN850 makes use of Western Digital's G2 controller and 96L TLC NAND flash memory. The 1TB drive being tested today is rated for 7,000 MB/s sequential reads and 5,300 MB/s sequential writes and 1 million IOPS for random reads and 720k IOPS for random writes.

RISC-V, the Linux of the chip world, is starting to produce technological breakthroughs

Filed under
Hardware

A decade ago, an idea was born in a laboratory at the University of California at Berkeley to create a lingua franca for computer chips, a set of instructions that would be used by all chipmakers and owned by none.

It wasn't supposed to be an impressive new technology, it was merely supposed to get the industry on the same page, to simplify chip-making in order to move things forward.

Cinnamon 4.8 Desktop Environment Released, This Is What's New

Filed under
News

More than six months in development, Cinnamon 4.8 is finally here and it already made its appearance on the software repositories of the Arch Linux distribution. But, it is designed with Linux Mint users in mind, as they are the main target of this GNOME-based desktop environment for GNU/Linux distributions.

The biggest new features in Cinnamon 4.8 include a new suspend-then-hibernate function that instructs the desktop environment to first suspend the system and then hibernate it after a certain period of time of inactivity.

  • Daniel Stenberg: I am an 80 column purist

    I write and prefer code that fits within 80 columns in curl and other projects – and there are reasons for it. I’m a little bored by the people who respond and say that they have 400 inch monitors already and they can use them.

    I too have multiple large high resolution screens – but writing wide code is still a bad idea! So I decided I’ll write down my reasoning once and for all!

  • Post Json API using curl | RNM

    I developed a restful as communication for our software and client. We let end point of our API to talk each other and i quite simple for small test using Postman or SOAP-UI but to test with massive data via API is quite headache.

    Lucky enough, I am good with unit test so since our system develop using java, then I use Junit as helper to help me do the automation test. It look nice but somehow I still have issue to remote test using Junit on my Eclipse IDE. It all because the remote server we connnecting is on customer premise and the connection are so bad!

  • Perl Weekly Challenge 088 | Samir Parikh

    Despite the holiday week here in the U.S., I was able to tackle this week's Perl Weekly Challenge. I have to say that this week's challenge was the most satisfying for me as it allowed me to not only come up with a novel solution (for me!), but it also provided an opportunity for me to leverage two areas of Perl programming that have been a real challenge for me: recursion and references. The deadline to submit solutions for this challenge is fast approaching so if you haven't solved it yourself yet, you may want to come back to this post later.

However, it’s going to be the 10th year in a row with a Perl 6 or Raku calendar, previously published in the Perl 6 Advent Calendar blog. And also the 5th year since the Christmas release, which was announced in the advent calendar of that year.

  • Journal five minutes a day with Jupyter | Opensource.com

    Some people follow the tradition of creating New Year's resolutions. A year is a long time, though, so I plan with a seasonal theme or trajectory. Each quarter, I sit down and look at the upcoming three-month season and decide what I'll work on during that time.

    For my latest theme, I decided I wanted to write a daily journal. I like having clear commitments, so I committed to writing for five minutes each day. I also like having observable commitments, even if it is just for me, so I put my entries in Git.

    I decided I wanted some automation around my journaling and turned to my favorite automation tool: Jupyter. One of Jupyter's interesting features is ipywidgets, a set of interactive HTML widgets for Jupyter Notebooks, JupyterLab, and the IPython kernel.

    If you want to follow along with the code in this article, note that making your Jupyter lab instance support widgets can be a bit frustrating. Follow these instructions to set things up.

  • Fanless Linux embedded system makes a compact IoT gateway

    ICP Germany has recently introduced the MiTAC ME1-8MD series family of compact, fanless Linux embedded systems powered by NXP i.MX 8M processor and designed to be used as IoT gateways, data acquisition and processing systems, and mini servers.

    Three models have been launched with a choice of dual or quad-core processors, up to 4GB LPDDR4 RAM, and 32GB eMMC flash storage. The embedded computers also come with up to two Ethernet ports, support up to two displays, and include an internal Raspberry Pi compatible 40 pin GPIO header.

  • Official Raspberry Pi 4 case fan adds cooling to Raspberry Pi 4 case

    When the Raspberry Pi Foundation first introduced the Raspberry Pi 4, they claimed the board would work just fine under most cases without a heatsink, and the latter was only really needed under load. That may have been true when using the board in a temperate climate like in the United Kingdom, but then Raspberry Pi 4 met Thailand with some benchmarks results lower than on a Raspberry Pi 3. People using plastic enclosures had even more troubles.

    It’s only when I installed a heatsink on Raspberry Pi 4 that the board could really shine. The company also provided some firmware optimizations later on to further cool-down the board. But you can only do much with software, and many third-party cooling solutions such as fansinks or metal cases have been introduced for the popular SBC.

    The company, called Edge Devices, has now launched an update with Pi-oT 2 adding optional support for 24V digital inputs, RS-485, and an uninterruptible power supply (UPS).

Kernel Leftovers

  • [Intel-gfx] [RFC 00/28] Old platform/gen kconfig options series
  • Patches Resubmitted For Linux With Selectable Intel Graphics Platform Support

    Back in early 2018 were patches proposed for selectable platform support when building Intel's kernel graphics driver so users/distributions if desired could disable extremely old hardware support and/or cater kernel builds for specific Intel graphics generations. Three years later those patches have been re-proposed. The patches then and now are about allowing selectable Intel graphics "Gen" support at kernel configure/build time so that say the i8xx support could be removed or other specific generations of Intel graphics handled by the i915 kernel driver. This disabling could be done if phasing out older hardware support, seeking smaller kernel images, or other similar purposes. The patches don't change any default support levels but leaves things as-is and simply provides the knobs for disabling select generations of hardware.

  • Linux Kernel Runtime Guard 0.9.0 Is Released

    Linux Kernel Runtime Guard (LKRG) is a security module for the Linux kernel developed by Openwall. The latest release adds compatibility with Linux kernels up to soon to be released 5.12, support for building LKRG into kernel images, support for old 32-bit x86 machines and more. Loading the LKRG 0.9.0 module will cause a kernel panic and a complete halt if SELinux is enabled.
