• Intel teases 'software-defined silicon' with Linux kernel contribution – and won't say why

  Intel has teased a new tech it calls "Software Defined Silicon" (SDSi) but is saying almost nothing about it – and has told The Register it could amount to nothing.

• RadeonSI Enables NGG Shader Culling For Navi 1x Consumer GPUs - Phoronix

  As another possible performance win for RadeonSI Gallium3D as AMD's open-source Radeon OpenGL driver on Linux systems is enabling of NGG culling for Navi 1x consumer graphics processors rather than limiting it only to newer Navi 2x (RDNA2) GPUs. Merged on Monday was a patch to enable shader culling for Navi 1x consumer SKUs with no longer limiting it to Navi 2x / GFX10.3 or when using various debug options. This culling was also enabled for Navi 1x GPUs but only for the "Pro" graphics SKUs.

• Speak to me! – Purism

  My trusty laptop’s speakers gave up the ghost. I don’t like to sit around in headphones all the time, I don’t have any other speakers, and the replacements are still being manhandled by the postman. I’d get used to the austerity if I hadn’t started missing calls from a friend. That’s unacceptable! But what am I supposed to do? Buy extra gadgets just to throw them away after a week? Nope, I’m not that kind of a person. But hey – I have a Librem 5! It has a speaker. It’s open. I have control over it, and I’m a hacker too. So I should be able to come up with a hack to turn it into a speaker for my laptop, right? Pulseaudio to the rescue. I look through the guide. There it is: forwarding audio over a network.

• LDAP query from Python · Pablo Iranzo Gómez's blog

  Recently, some colleagues commented about validating if users in a Telegram group were or not employees anymore, so that the process could be automated without having to chase down the users that left the company. One of the fields that can be configured by each user, is the link to other platforms (Github, LinkedIn, Twitter, Telegram, etc), so querying an LDAP server could suffice to get the list of users. First, we need to get some data required, in our case, we do anonymous binding to our LDAP server and the field to search for containing the ‘other platform’ links.
