[11:04] schestowitz[11:04] schestowitzIn previous posts the topic of color management in Cairo was examined. Since then people have told me a few things about the issue. According to them (and who am I do to proper background research and fact checking, I'm just someone writing on the Internet) there are a few fundamental problems with Cairo. The main one is that Cairo's imaging model is difficult to implement in GPU shaders. It also is (again, [11:04] schestowitz according to Internet rumors) pretty much impossible to make work with wide gamut and HDR content.

[11:08] schestowitz[11:08] schestowitzAs we covered in History of FreeBSD Part 4: BSD and TCP/IP, TCP/IP was brought to Unix with BSD first. Many common network utilities like ifconfig, route and netstat date back to the 4.2BSD release and spread from there to other Unix systems. Linux started out with similar utilities modelled on the BSD utilities; these packages continue to be widely available, but most modern Linux distributions have [11:08] schestowitz deprecated them in favor of alternate utilities such as ip(8).
[11:08] schestowitzThe change on Linux came about alongside a redesign of the kernel interfaces where use of the ioctl(2) system call was replaced by a more flexible socket based interface called netlink. Interestingly, netlink support was recently added to FreeBSD and should be available in FreeBSD 14. This is mainly relevant to the use of the linuxulator, for running Linux applications and containers, but should also make [11:08] schestowitz it easier to port Linux software to FreeBSD.

[18:07] -TechBytesBot/#techbytes-www.raspberrypi.com | Supply chain update - it's good news! - Raspberry Pi [18:07] schestowitz[18:07] schestowitzAs a thank-you to our army of very patient enthusiast customers in the run-up to the holiday season this year, weve been able to set aside a little over a hundred thousand units, split across Zero W, 3A+ and the 2GB and 4GB variants of Raspberry Pi 4, for single-unit sales. These are flowing into the Approved Reseller channel now, and this is already translating into better availability figures on [18:07] schestowitz rpilocator. While were not quite out of the woods yet, things are certainly improving. For those of you looking to buy a Raspberry Pi for hobby projects or prototyping, the advice we gave back in April still holds: always buy from an Approved Reseller (theyre under contract with us to sell at no more than the RRP); use tools like rpilocator to keep an eye on which resellers have recently received stock; and consider whether your project is a [18:07] schestowitz good fit for Raspberry Pi Pico or Pico W, which remain in a strong stock position. And if youre an industrial or enterprise customer who is experiencing supply issues, and you have not already spoken to us, please get in touch with our commercial team at business@raspberrypi.com.

[18:09] -TechBytesBot/#techbytes-blog.josefsson.org | Trisquel 11 on NV41PZ: First impressions Simon Josefsson's blog [18:09] schestowitz[18:09] schestowitzMy NovaCustom NV41PZ laptop arrived a couple of days ago, and today I had some time to install it. You may want to read about my purchasing decision process first. I expected a rough ride to get it to work, given the number of people claiming that modern laptops cant run fully free operating systems. I first tried the Trisquel 10 live DVD and it booted fine including network, but the mouse trackpad did not work. [18:09] schestowitz Before investigating it, I noticed a forum thread about Trisquel 11 beta3 images, and being based on Ubuntu 22.04 LTS and has Linux-libre 5.15 it seemed better to start with more modern software. After installing through the live DVD successfully, I realized I didnt like MATE but wanted to keep using GNOME. I reverted back to installing a minimal environment through the netinst image, and manually installed GNOME (apt-get install gnome) since I [18:09] schestowitz prefer that over MATE, together with a bunch of other packages. Ive been running it for a couple of hours now, and here is a brief summary of the hardware components that works.
