> How do you unmount your OS’s disk while keeping the OS running to be able to overwrite itself? I went down a similar rabbit-hole myself, with the goal of safely replacing the Linux installation on a disk that a machine is already runni

How have you measured the power usage/cost? That seems like a incredibly high price for electricity, similar to a 600W constant load in my part of the world.

In distributed databases I've worked with, there's usually something like a B-tree per key range, but there can be thousands of key ranges distributed over all the nodes in the cluster in parallel, each handling modifications in a

To minimize the storage space while having a URL-safe representation, yeah you'd want to serialise/deserialise on the boundary of presenting it to API consumers. I think the same for any ID that has an efficient binary representa

> UUID versions 1, 2, 3, 4, 5 are already outdated. Interesting comment, since v4 is the only version that provides the maximal random bits and is recommended for use as a primary key for non-correlated rows in several distributed databa

You aren't supposed to store the hyphens, and that's the same for all versions.

I have a machine with a 6 year uptime that was slowly accumulating single bit error corrections. The EDAC counter mysteriously stopped at 308 last year, and hasn't changed since, so I wonder if a bitflip in the counter circuit made it

You can only detect what you measure. Are these big-data analytics processes running multiple times to detect differences?

The actual RAM chips on a ECC DIMM are exactly the same as a non-ECC DIMM, there's just an extra 1/2/4 chips to extend to 72 bit words. The main reason ECC RAM is slower is because it's not (by default) overclocked to th

I think it is still more likely that a project can be improved if everyone has access to the source code vs not having access to any source code. Are there counterexamples to that?

Intel seem to be deliberately hiding the clock frequency of this thing, the xeon-6-plus-product-deck.pdf has no mention of clock frequency or how LLC is shared.

Did you try adding a Cache-Control response header?

> it took 5–10 minutes just to open a file Yeah, I don't think the architecture is going to help a bad storage/network setup too much. I'd be troubleshooting that before jumping machines/OSs.

Did macOS support that at some time in the past? I've used Linux as my daily OS for 20 years and got so used to alt-right resize and alt-left drag that the macOS and Windows way of actually needing to move my mouse to the corner or edg

I like this theory - I can totally imagine some big spreadsheet of processor model names where someone copy/pastes the model name to some janky firmware-programming utility running on an off-the-shelf mini PC on the manufacturing floor

Windows 11 24H2 added a dependency on the POPCNT instruction, causing CPUs that don't have it - which were otherwise fine, to fail to even boot Windows. What will be the next instruction/ISA extension that is only supported since

If you bypass the installer minimum hardware checks then you're making a gamble that the official statement from Microsoft won't affect you: > If Windows 11 is installed on ineligible hardware, your device won't receive su

This supports up to 48x 256GB DIMMs over two sockets, which I believe is the maximum that EPYC Turin supports: https://www.asrockrack.com/general/productdetail.asp?Model=T...

It would be nice to see a design document where the alternatives were considered and why this was invented to fill a gap. Otherwise, this just looks like reinventing the 20+ year old libvirt XML VM format.

That specific IP is detected as anycast by bgp[dot]tools , which is likely as it is announced from AS13335, so backbone routers will choose the best route back to the multiple places it is announced from. If you traceroute such an IP from

It's more about demonstrating what's possible on a Pi than expecting GPT-4 level performance. It's designed for LLMs that specialize in tiny, incredibly specific tasks. Like, "What's the weather in my ant farm?&quot

A point in screen space is a line in world space after inverse camera projection, so this way you get the line-to-closest-geometry test in O(1), after the overhead of needing to render the lookup texture first.

You can fool the optimizer, but you have to work harder to do so: unsigned add(unsigned x, unsigned y) { unsigned a, b; do { a = x & y; b = x ^ y; x = a << 1; y

Perhaps it's improving the checksum algorithm on network packets, or even ... adding one.

Dithering isn't only applied to 2D graphics, it can be applied in any type of spatial or temporal data to reduce the noise floor, or tune aliasing distortion noise to other parts of the frequency spectrum. Also common in audio.

Seems to me the real problem here is not the timezone (there's legitimate business needs to run something daily at a specific localtime...) but having multiple instances of a cron job that overlap, in which case it should wait until th
