Generally speaking the vendor libraries have dynamic dispatch support, which can identify which functions are available on a CPU and then deploy to the best at runtime. Intel got into some hot water for having their dispatch hurt performanc

Public release date for Zen4 server has been disclosed for November 10, FYI. https://www.servethehome.com/amd-epyc-genoa-launches-10-nove... . Looks like Intel's release is coming January 10. https://www.toms

This was standard practice at my former old school tech company employer. People were "redeployed" and given 30-90 days to apply for new roles, with many unable to get jobs secured in time they were let go with minimal severance.

I remember working on an audit of JWST back in 2012-ish and thought that it would never be launched or, if it did, something critical would fail. I'm happy my doubts were proven wrong

Can you elaborate on what you'd expect to see if they tested the highmem node configs?

In the PC division apparently, not across the company or in data center focused areas. Gazillions still needed in those areas

Yeah but I wonder whether the users can tell the vendor under disclosure rules. It is really weird that they didn't tell AMD at the same time!

Why did they wait 2 extra quarters to tell AMD about this?

Ohh, don't mind if I do! I'm working on CPU libraries to improve compression performance. Does zstd benefit today from ISAs like AVX-512, AVX-2, etc.? Do you foresee the need in the future to offload compression/decompression

Apparently not, but I only just noticed after their free 1 year trial of SSL certs expired. They're listed on the Let's Encrypt site as having no plans to support and the source is pretty hilarious: https://community.le

This is a very nice recognition! I realized that the registrar I have my personal site with purposefully does not support Let's Encrypt as a CA. Anyone have a registrar they'd recommend these days to transfer a domain to? FYI, the

The fact that Paul Graham tweets were a factor in considering this company is worrisome, at least to me.

Anyone have a good resource for how Perf compares to vendor tools like vTune and uProf? Is there another perf tool for Arm or is that even necessary?

Great news! Adblock Plus has been compromised for quite some time. This means the pressure will definitely increase on uBlock Origin but I hope they stay strong.

And how about treating your contractor labor as real employees next, eh? Why not give them some nice, shiny, new hardware?

I'm more concerned about a company being able to see what you do on your personal computer, which is what the comment seemed to allude to. I know there are many sketchy tracking mechanisms out there, but if they can extend to your pers

Whoa... the part about being able to trace if work is being done on another computer is alarming. How can they do that?

Way to burn bridges on the way out. I see no benefit to doing that when you're just going over to work on Chrome malarkey and get more t-shirts

I wouldn't be surprised if they're pricing them below cost like they have done with Alexa products.

Aren't the Zen3 instances still faster than Graviton 3? DDR5 is interesting, and while lower power is nice, the customers don't benefit from that much, mostly AWS itself with its power bill. I haven't seen pricing yet, but a

Any suggestions for a CO2 monitor that doesn't require you to solder? I have an Arduino and a breadboard so can hand wire things in the meantime if needed...

Well, for one, we don't want a humanitarian crisis and civil war or even international war... that's bad for the whole region and thus bad for US interests. We also don't want China able to just take over land and territory a
