Or it was undefined behavior in your code, like depending on the evaluation order of function parameters, or one of mine, testing an array element before testing the index was within bound. Broken: table[table_i].values[j] && j<c

Yes, as far as I know, astronomers think so. Those are exoplanets. Planets without any nearby stars. Even in our own solar system we don't know whats out in our Kuiper Belt. Probably nothing too big or we'd be able to measure the

It is definitely a problem of defective hardware. But there are plenty of people out there with both Intel and Ryzen systems who disable every C-State and every Turbo setting because any change in power levels causes their system to crash.

The standard controllers included on my ASUS Pro x370 board show you don't need a add-in controller. It's got 8 ports on the board, and when I do btrfs scrubs the 6 HDDs get 760 MiB/s and the 2 SATA SSDs get 1.05 GiB/s.

To support a large disk array you just need a few things. - Lots of drive connectors. - That can be an 8 port SATA motherboard. - A SATA HBA card. I've seen some with up to 24 ports, or some of these support port expanders whic

If you do have hidden thread safety bugs you are only one compile away from failure, even on x86. Some function gets vectorized and a variable shifts in or out of a register? Or one of your libraries gets rebuilt with LTO / LTCG and it

An Intel iGPU can run dual 4K displays just fine, if it has dual channel RAM. I'm still upset at Lenovo thinking 16 GB should come in one RAM stick. If you have a Thunderbolt USB-C port then you have a DisplayPort. Some monitors accept

I seem to recall using it to auto-adjust column widths. And we did something with it involving string translations. Since we didn't control the translated format string we couldn't just count the characters in the source code. But

"throttles" Are you certain you don't mean "stops boosting" when you say that? I'm running exactly the same: a 3900X with the default included cooler. Yeah, it hits 95C and at that point it's running at 3.

You're exaggerating for effect, I assume. Rust compile does not require that much RAM. Now, by default the "cargo" build uses all CPU threads, so if you have a 32 core Threadripper then yes, running 64 simultaneous "rust

As far as I know it's a fundamental kernel architecture decision that Microsoft can't just "fix." From the original NT microkernel design, filesystem access is all asynchronous messaging, and it can be intercepted and mo

Basically no impact. At least for me. Some people seem to get terrible performance, but I don't know why. Their drivers? Or is it trying to run without Virtualization enabled in BIOS? AMD-V, VT-x, VT-d? I don't consider it odd. It

As I understand it they've borrowed techniques from SSD firmware. Random writes are written to a linear cache area of the drive and transparently remapped. When the drive gets idle time it will rewrite the SMR zones where those blocks

It is extremely easy to let your C++ code get into long build times. People get fond of putting code into the header, for example. This adds that compile time to every file that includes that file. And it prevents you from using forward dec

The only other practical idea I've ever heard of is serving a dynamic page to a CDN. Which means it was made into a static page. On the CDN. Wooo, progress!
