Dang, they aren't catching the booster this time, but I guess V3 is practically a new vehicle and validating the next Starship launch is probably too critical to risk damage to the…

In Zulip, if a thread meanders with messages about a tangent, the authors/mods can choose to move those messages to a new thread (and IIRC messages with links between the two threa…

If you're laying a communications cable, you should just do fiber. It can carry any type of traffic at high data rates, and you can upgrade the speed over time by just replacing th…

Yeah, as far as I know the only way to be sure is by putting the parent process into a cgroup. Then to kill all of the child processes you have to freeze the cgroup, enumerate the …

very slowly, with the radio at maximum power, and no obstructions

It uses a different transceiver on the satellite which is broadcasting a ~standard LTE signal, at a miniscule data rate

I looked around last week to see if they are on the market yet, and found that Philips already seems to have helium-free MRIs for sale. I'm not sure if they just sealed it better o…

The Linux kernel doesn't have a stable ABI. Thus, if a kernel function signature changes, or a subsystem gets refactored, etc, drivers get updated as part of the process. If the dr…

Not sure what you mean by "userland" drivers here, but support for kernel modules written in rust is actively being developed. It's already being used for kernel drivers like the A…

Wait, Commonwealth Fusion Systems is already building 20T REBCO magnets, can't those meet the requirements for MRIs?

Why would you use LVM with ZFS? ZFS should handle all of the features LVM has (as far as I can think of, at least).

I would have taken a full screenshot but I had my company's Gitlab open behind it.

This is called dog whistling, and is frequently used to subtly spread racist and fascist views. If you're not doing that, arguing in bad faith is a waste of everyone's time and pro…

Rust references are basically pointers with extra rules, so using a different symbol is reasonable, and rust is immutable by default rather than opt-in (which is an important desig…

Back in my Windows XP days I had an app installed called Desktop Sidebar[1], which would be exactly the place I'd want all of this functionality today. Or in some kind of widget la…

Because usually they are implementing a subset of the network stack that meets their needs for communication within their internal network. Porting the entire kernel stack that act…

> no one ever bothered to put something together on UNIX-like systems that resembles any of those options. What do you mean? io_uring is a Linux kernel interface, and there are sev…

If you didn't disable the write cache on those drives, flares could have caused bit flips in the cache memory before it was flushed to disk.

Are you able to store that data in reference-counted RC/ARC types? Those can help you avoid dealing with lifetime issues, though you'll still have to think about mutability and con…

The only telemetry you get will be from users that are experiencing a severe problem who also have the technical know-how to turn it on. You will have no idea how prevalent the pro…

How stable should property ownership be in an area experiencing growth? I think this could be tunable with short term price increase caps that expire 5-10 years out, and reset when…

No one is going to donate to something unless they're aware of it, so spreading awareness does help increase the potential pool of donors.

They don't want people distributing unofficial builds that claim to be Signal due to the risk of supply chain attacks against users.

You also need to futz with apt repo priorities to force it to install the deb package instead of the snap installer -_-
