I wouldn't say so, because it was a co-processor: e.g., it depended on the 8086 to even generate addresses for memory operations. I think the IBM 7030 Stretch CPU (from 1964) would be a likely contender for being one of the first 64-bi

The levels tool maps a subset of the channel range to the full range, effectively changing the brightness and contrast in one step. The center point controls the gamma correction, so you can map a biased distribution (mostly bright or dark

The more popular your software is, the more likely you'll get bug reports from people with just bad hardware. I know a few applications now that perform a simple memory/CPU test when sending a bug report and reject those that are

I meant that it's a difficult comparison between platforms without having all the details like memory latency, how the memory controller load increases latency (can increase by 4x on some platforms), cache latency, TLB entries, etc. Ex

Thanks for this, really interesting parent project too, I went down a rabbit hole on that one :)

It's higher bandwidth than any dual-channel DDR5 desktop machine, but Apple never quote the memory latency, so hard to compare otherwise.

It installed and runs perfectly on my VM with an RTX 4080 passed-though using VFIO. It uses the nvidia module rather than nouveau (at least on my GPU).

Encode every 0 as 10 - then decode every 10 back to 0. Or more efficiently, the first 0 as 10, then decode the the first 10 as 0.

OAuth is designed so that an end-user never needs to see an API key (OAuth refresh/access token) or even know what one is. When it is implemented to the spec, that happens well. I think that most of the "just give me an API key&q

I can think of a few reasons: There wasn't any such features for x86 when the patch was created, other than AES-NI. Many hardware platforms that have TPM, have it connected via a low-bandwidth LPC bus which would have nowhere near enou

There was a patch called Tresor that did this, but I don't think it was updated for a long time. You have to store the encryption key in CPU registers and ensure it's not saved to RAM during task switching or power suspend operati
