Rust's std::sync::mpsc contains most of the hazards of Go's channel, and arguably adds some because the Go runtime provides deadlock detection that Rust lacks.

This seems to have little to do with Go's facilities. Any concurrent program has hazards like these.

What primitives are we discussing? Any Go programmer can and should use the `go` keyword and the `sync.Mutex` type from their first program.

The economy does not occur naturally. We can turn the knobs on this equation by just having some taxes. For example, carbon taxes. That should change your calculus pretty significantly.

It's long been possible (since Alder Lake at the latest) to tune Intel CPUs for task energy consumption competitive with Apple Silicon, but bone-headed OEMs including Apple always tuned them the other way, wasting a lot of power for ti

When they opened retail outlets it was the beginning of the end. That was the peak of their growth rate and the moment when Dell really started to go after them.

traditional physics-based weather models also rely heavily on humans looking at the output and the evaluation of the output to discard wacky runs. Let's not pretend that existing physical models of the atmosphere stay on the rails all

One nice thing to remember is for projects you control, you can dictate the ABI. There isn't a law enforcement bureau that will arrest you for passing parameters in whatever register suits you. You just have to imagine life differently

Tech sector is not the bulk of it, many sectors doing worse and that is why they got the headlines. "Financial Activities" supersector was terrible this month. Another reason is there is not an umbrella "tech" sector in

There's always a competency shortage in this kind of aviation because the crew are inexperienced people trying to get a higher rating and a better job. The big transport aircraft are so easy to fly now, they should probably switch the

I am not sure what you mean here. I just checked my uploads and all my live music stuff is still there, as well as obscure published records.

This isn't true. I have tons of stuff that I uploaded that they've never heard of

Nah. If USA returns to its senses we are going to need tons of tradespeople to build all the stuff we need for the billion Americans.

In addition to cycles, I suggest gathering TLB miss rates. eBPF isn't magical and any maps of significant size may pollute your virtual address translation caches. The last time someone asked me to profile eBPF at work, over 90% of the

It's pretty wild that 99% of participants came from Instagram, Facebook, or Tiktok. It never escaped that bubble? The other platforms, Reddit, YouTube, word of mouth only amounted to 1%?

Redis uses jemalloc by default, if I recall correctly, but its hostility to the way systems actually work arises from the way that it forks, then changes one bit on every page in the entire virtual space, which causes a lot of kernel work t

Linux also has support for it but it is up to the distribution, or the user, to enable or disable it. The whole discourse was poisoned years ago when the author of Redis told everyone to disable THP on Linux, but this was caused by Redis be

One of the drawbacks of relying on the virtual memory subsystem is large page tables, that the machine has to manage on your behalf, and that pollute (or at least occupy) caches. That is another reason why Go, like all other software, benef

Sure, with LSE. But you have to target LSE and get a system that actually contains it, i.e. not the default compiler flags and not the original AWS Graviton.

The combination of "I have an idea for changing one of the fundamental experiences of modern life" and "my website is obnoxious and hostile" didn't really work for me.

Whether the allocator calls are "naive" or not depends entirely on the allocator in use. If you need thread/core locality and batching you can get that by replacing global new/delete functions with a decent allocator.

I don't think gcp customers were hoping for higher latency, 5% packet loss, and modem speeds.
