You can render one line of output and DMA it to the display. So no need to have a complete framebuffer in the first place. Lack of memory just limits the number of textures you can have.

"So with this, the last thing Go had going for it over Java is gone, right?" You can deploy Go app with a single binary, no runtime required. No runtime configuration.

$2M a pop, though. These packs in question are huge, meant for grid-scale solutions.

Just need to put two of these -10x engineers working together. The results should be amazing!

> If you record a future PST date as UTC and PST changes, your recorded date is now wrong. Damn. That's a very good point. From now on, I'll be always recording also timezone, especially when it comes to future dates!

"parallax fails to detect it" AFAIK, pretty much none of the driverless systems are using parallax. The reason why not is that parallax only gives good depth information at most up to about 10 feet. Disparity mapping is pretty lim

No "free" command. With "top" command I got this: MemRegions: 1744370 total, 5771M resident, 234M private, 4726M shared. PhysMem: 31G used (2888M wired, 15G compressor), 74M unused. A bit confusing even for someone who i

I'm typing this on a Macbook M2 max with 32 GB RAM. Not all that much open and the memory usage is at 27 GB. Chrome, Teams etc. messaging apps, Xcode and other SW dev stuff. Kinda regret I didn't go for 64 GB.

China is going to throw Russia under the bus at the first opportunity. Russians are foolish to think that China will be their ally. China just needs Russia's resources for now.

I think that's how pretty much all of the high-performance desktop & server CPUs operate now.

Same issue here, found anything good?

One good way to start learning assembler on most architectures is with gcc/clang output and learning by modifying it.

Apparently both cases were "remanufactured" cars, after a build process failure. A flaw in the process for cars that go back to the manufacturing line, to be rebuilt?

Tesla was the top one also in avoiding accidents. See Euro NCAP test.

Euro NCAP etc. seem to classify Teslas as (some of) the safest vehicles on roads. https://www.euroncap.com/en/results/tesla/model+y/46618 Same for NHTSA: https://www.nhtsa.gov/vehicle&#x2

While that may be true, my experiences from Motorola 68k times still make me shiver. 68k used just bottom 24 bits for an address. Later models used full 32 bits, breaking anything that used the top 8 bits for something else. The introduced

A bit dangerous feature to use. Carelessly used it can lead into a platform lock-in.

Kinda. Not like it'd produce a wrong result, but you could say it's a bug (presumably) in the out-of-order scheduler.

I use both. They're cheap as chips, so why not? ESP32 doesn't have RP2040's PIO. It's just amazing, and can easily emulate RGB display controller or whatever you want it to. Even software HDMI with most CPU power still a

Surely you mean 262,144 4k pages?
897.
by vardump 4y ago
Different applications would certainly benefit from different page sizes. Use 1G pages, and boom, TLB misses and faults are just gone . But definitely not a good default choice! Any choice is a tradeoff. The larger the page size, the more
898.
by vardump 4y ago
4k pages are too small and 2 MB pages too large. I wish we x86 users had 64 kB pages. 4 kB pages reduce CPU performance due to frequent TLB misses and make virtual memory perform worse due to number of faults.

I wonder how Tesla is planning to remedy this. Not great for certain climates for sure.

Soon enough (2030+) someone's going to solve NIB batteries (mainly sodium refining, I guess) and a bit heavier, but dirt cheap sodium ion batteries are going to be everywhere . https://en.wikipedia.org/wiki/Sodium
