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.

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.

    Ova Magica, a blending of casual farming in the spirit of Stardew Valley and Harvest Moon blended with monster taming and battling like something out of Pokemon is now live on Kickstarter. It managed to get fully funded within the first 2-3 hours, which I'm really not surprised about. The early tech demo was promising and it has such a great idea. Thankfully it's another that will support Linux too and the developer has been very clear about this. The Kickstarter campaign also lists it nice and clear as "The game will be released on PC DRM-Free, on Steam (Windows, Mac OS and Linux), Nintendo Switch, Playstation 4, Playstation 5, Xbox One, Xbox Series X/S.".

  • WordPress security & hardening, the definitive guide

    WordPress is massively popular. Around every one in five sites on the Internet uses WordPress in some form. Be that to run a humble blog, or a multi-site Content Management System (CMS) or eCommerce site. As a result, it is no surprise that WordPress websites are a very popular target for both experienced hackers and script-kiddies alike. The last thing any webmaster wants is to find out that their website has been hacked; maybe taken hostage and is part of a botnet, spreading malware, or partaking in Denial of Service (DoS) attacks. In this article we’ll be sharing a number of tips and strategies to help you harden your WordPress website.

    This is the fifth post in my series on voting systems (catch up on parts I, II, III and IV), focusing on computerized voting machines. The technical term for these is Direct Recording Electronic (DRE) voting systems, but in practice what this means is that you vote on some kind of computer, typically using a touch screen interface. As with precinct-count optical scan, the machine produces a total count, typically recorded on a memory card, printed out on a paper receipt-like tape, or both. These can be sent back to election headquarters, together with the ballots, where they are aggregated.

  • Jessica Rosenworcel’s appointment is good for the internet

    With a new year comes change, and one change we’re glad to see in 2021 is new leadership at the Federal Communications Commission (FCC). On Thursday, Jan. 21, Jessica Rosenworcel, a longtime FCC commissioner, was appointed as acting chair. It’s an important role that will drive policy discussions affecting the internet and all of us who use it. Her appointment gives us hope that under her wing, the agency will develop strong policies that look out for everyday people. Here are a few reasons Jessica Rosenworcel’s appointment is good for the internet. [...] We look forward to working with the FCC to reinstate net neutrality protections and close the digital divide. Jessica Rosenworcel’s ascent to acting chair of the FCC bodes well for the future of both issues. And we can imagine a brighter future for a healthy internet if she were to be nominated for the role permanently.
