awk, sed, cut, etc... are excellent as long as the format is regular and you only need to process the file once

This may seem like an odd question, but strategically, why acquire the stake (aside from dividends)? As I understand, ASML already depends on Carl Zeiss. I would guess ASML will de…

People and businesses in countries like Venezuela, where the native currency is volatile and under strict government control, use cryptocurrencies. They're more stable (not as stab…

Okay... I agree adding features to email and IRC are probably not the easiest things in the world. There are a number of useful features that have been added to email over time tho…

I'm a huge fan of the IRC protocol, and I think I've set up IRC channels at nearly every company I've worked for. Freenode and Weechat seem to support the changes, but I honestly w…

Seattle has set up more than one tiny house village [1], at least that I know of. Some of them even have internet access. We still have a very real homeless problem though, and you…

It's estimated there are 10^80 atoms [1] in the visible universe, so 2^256 is definitely a huge number. I didn't realize 256 bit brute force was nigh feasible with only a solar sys…

ORWL was designed specifically to prevent undetected tampering with any of its electrical components, including the entire motherboard and storage drive. When tampering is detected…

I personally think life is probably common in the universe. We've only been able to prove exoplanets exist within the last few decades, but the evidence is already that there are a…

This is a really good point. There has been a lot of research into this area lately, as well as animal intelligence in general. My point is still that life less intelligent than us…

Two civs probably need to be within half a millennium or so of technological development (human time) to have any possibility of communicating. Intelligence seems to expand polynom…

Yeah, I'd care about that octopus. I would want to study it and see what else it does. Sure, I mean intelligent life is interesting to us because it's novel. If there is other inte…

I think it's likely intelligent life outside our planet just doesn't, or won't, have any interest in us outside the infinitesimal possibility of a threat. Consider everything less …

jvisualvm is largely a superset of jconsole , with a plugin interface, so it probably is. I have no idea how many other people actually use it though.

If it's exposed through JMX, would it also be visible via something like jvisualvm ?

Autonomous software is a lot more complex than the software the ECU uses (which is still complex), so there may be a genuine argument against allowing people to modify cars not des…

Autonomous driving isn't really regulated though. Google's Chauffeur is the only autonomous software I'm aware has even passed a state driving test.

“It is fully functional. It’s about on par with Tesla Autopilot,” Hotz said. It doesn’t have a lot of sensors as the Comma One relies on built-in car front radars and comes with a …

I would be genuinely curious what the development methodologies for Chauffeur look like, if anyone can point me in the right direction.

Another minor thing I think belongs in the C standard is bswap . For such a common operation that's necessary for portable code, I personally don't understand why it hasn't been de…

This doesn't say anything about pointer arithmetic on pointers to raw memory though. For example, using an mmap file, there isn't any object, and there aren't any bounds.

I can see that a non-linear address space doesn't imply a strict weak ordering, but this still seems to be an implementation defined detail. It doesn't imply anything about pointer…

Accessing beyond bounds is undefined, but leaving pointer arithmetic outside of objects undefined would preclude a lot . For example, building an OS page table or DMA, or RDMA, or …

Non-linear address spaces shouldn't affect pointer arithmetic though, unless I'm misunderstanding something. Otherwise, I guess the implication is that there are systems or impleme…
