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 depend more heavily on them with EUVL over the next decade, b

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 stable as USD/EUR though) and easier to transact (par

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 though, and I don't think decentralized control of the pr

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 worry that the protocol ends up more complicat

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'll see panhandlers if you drive through the city. Pe

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 system. I'm a bit surprised the quantum algorit

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, ORWL immediately and irrevocably erases all your data, ev

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 number of planets that are hospitable to life (our ki

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 has nothing to communicate to us that we would care to res

by uxcn 10y ago
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 polynomially or exponentially by a lot of measures though (e.g. t

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 intelligent life in the galaxy (universe), it proba

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 intelligent than us on our planet... If anyt

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 designed for autonomous driving. It definitely raises a really

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 camera. This seems a bit precarious.

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 defined in either the C or C++ standard. Curr

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.

by uxcn 11y ago
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 arithmetic overflow. For example, consider x86 s

by uxcn 11y ago
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 MMIO, etc...

by uxcn 11y ago
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 implementations that rely on negative pointers; in which

Pointer arithmetic overflow frightens and confuses me. Does anyone know why it's treated differently than unsigned arithmetic?

This is why I avoid allocating large VLAs, and using them in deep call stacks in general. There's a diminishing return for allocating on the stack beyond a certain point anyway (roughly around a page). Having a mechanism to abstract t

One minor thing that should hopefully be considered... a %b/%B conversion for printf et al. It's useful to print binary representations of things (debugging, conversion, etc...). A number of libc implementations support it as an

I thought the book was great. It's a quick read, but easily increased what I could do with tmux. I can't think of much more it really needs. Maybe cover stuff like if-shell ? The true-color patch might also be worth mention.

You're book is great for getting up to speed with tmux basics. The intro to tmuxinator was also pretty helpful. One of the bigger things I think people miss is copying text into and out of tmux panes, including to the clipboard. Thi

SSE performance is better than x87, for a number of reasons. Latency and throughput are generally better, but SSE also supports SIMD which allows more than one op per instruction. SSE also has more registers (x87 only has 8 80bit compared
