I've been working on a micro Linux distro for a couple of months now. User mode is just a single static binary (and a few files to support confidential microVM containers). The initramfs is such an interesting feature, the kernel kno

Compare the size of the new air-cooled 40XX cards and the iChill 4090, which is tiny by comparison. The simple answer is just to use liquid cooling if you have a card using 400w. Then all the absurdity just goes away.

Rust is also discussed at 35:00 into the presentation, noting the lack of a spec, higher memory util, and no commmercial vendor.

ProxyJump was added in OpenSSH 7.3 so systems from a few years ago might not support it. It does the same thing as ProxyCommand with -W %h:%p but you can’t set custom options for the jump connection with ProxyJump.

Yes, the kernel will map virtual to physical however it sees fit, no guarantees there (at least not in user-space via glibc). Realloc will always return a virtually contiguous slice or NULL if it can’t. And you’re right, obviously all tho

You can use realloc. It will try to use the existing contiguous span of memory, but if it cannot, it will malloc a new span and copy the previous bytes in and return a pointer to it.

Someone has to make a business case to get the chargers on the street. There are questions like who owns the sidewalk, how to route sufficient power there, capital outlay for digging up the street and getting the charger there. All those

The throughput is amazing. The screenshot shows 28,375 MB/s — the capital B typically indicates Bytes whereas a lowercase b indicates bits, so your Gb/s translation is a little confusing. The latency is still much higher than main

The upcoming MKTME support in future Intel processors will hopefully make this problem simpler to solve.

This is from mid 2017. "First notified Tesla on 31/08/2017 .. Tesla vehicles produced from June onwards use a new key fob". Not sure if the new fob is significantly better as the presentation is not clear there.

This is promising, but for dedicated high-performance I/O I am much more interested in how the SPDK is progressing. Avoiding syscalls is great, but without any benchmarks I wonder about the benefits over mmap and vectorizing. You stil

Curious to know if they block Google’s DNS servers as well. That 1.x space was a RIPE research segment, so it’s possible that some internal AT&T group was using it with the assumption it would not be publicly routable and got bit. I wa

If the math works there — could now or over time — then once L5 hits imagine the possibilities. L5 trucks towing broken L5 trucks with a third taking the cargo. I missed the video, but I’d bet huge that needed tech is probably prototyped

The reserved instance pricing model is really poorly implemented. You have to commit to an instance class and a region, and if you need to change you can, but there is some secondary market. When compared to a sustained use model, it is a
