Also if you have multiple instances, I guess it is better to not allocate N versions of the same thing in anonymous memory.

Even with store-load fw, you get a penalty (~3 cycle latency) over register accesses, no?

Well go also uses its own assembler, on top of that a kind of modified garbage version of real ones. You can only justify so many reinventions of the wheel, yet they redid everything .

Yet you nearly always blindly download and execute code when you browse, in overly complicated software in which dozen of vulns are found each month, with little hope of that slowing down.

Risc V is made to be boring. It does nothing to "challeng[e] existing assumptions about Von Neumann architectures and instruction sets". It is also very unlikely to become the next high perf ISA for tons of reasons, it is more sui

I'm not sure this is cheaper to fly, but part of the reason this is too cheap is that fuel for airplane is not taxed...

This also affects freeware / shareware / people who want to avoid "store" monopolies and their associated tax. This also affects people who are used to download binaries from reputable sites, because Google did not manag

Giving up things like modern medicine would not be reasonable. Giving up air travel, or at least reducing it vastly, would be merely an inconvenience. Well yeah, giving up air travel entirely would be somehow a mess, but even there it is

The A320 family actually includes the A319 (smaller) and the A321 (bigger), and the A321 (or A321neo) is quite similar to the 737 you selected: 737-800. Even the 320 is only slightly smaller than the 800; and it is quite bigger than the 700

This is a professional reaction to a shitty situation they created mostly themselves. The proper even more professional thing to do would have been to not react to the initial troll in the first place.

A single troll has managed to create an insanely huge drama and loss of tons of people time. I'm not optimistic about the future of Free Software. Especially with the new tendency of some projects to consider that people can be offende

That's kind of a marketing distinction. VS is not a kind of monolithic spaghetti monster system: internally, it is made of components, which provide a text editor, indexing for various languages, etc. You can do likewise with VS Code o

I had to check to see if it was a repost of e.g. an April joke proposal or something like that. Nope. One guy randomly wants to arbitrarily limit random Python things to 1000000, cite vague optimization potential advantages (in CPython, yea

That's kind of the "same" problem given we are not going to ditribute power of solar provenance by traveling half the earth. Likewise for wind: the distance are enormous to get reasonable wind diversity. So in practice it is

Well, I don't have very good experiences of XFS in the presence of system crashes; you are not alone to get irreparable FS. And even without crashes, the tooling is not very good. And the thing is that even with uninterruptible UPS,

WSL is vastly different from the old-school NT subsystems. Both in the technology and in the result. And rightly so, because while SFU&co was in some way more integrated, it effectively was a separate platform from anything else, and wh

You can not get exponential increase of energy efficiency. In some cases you even obviously already know the limits. At one point or another you will always be caught by physical realities; if all your activities are tertiary and highly v

The question is only semi-specific and the result depends on a ton of variables, like: which libc do you use; which kernel (maybe a patched linux kernel like on Android, don't know if they change anything regarding memory alloc though)

Windows has a notably very slow VFS, and less than stellar internal locking in some cases (including process creation/destruction). That makes for example compilation jobs sometimes WAY more slower than on Linux.

I'm not 100% convinced by the 5115 vs 4116, but that will depend on the workload. The case is clear for the 6126, but "For just a few hundred more dollars" is a bit dishonest; you are talking about $1000 (for the 4116) vs $17

I'm sure you studied a lot of accident reports and analyses. I'm sure you know the human factor plays a role in tons of cases. What I don't quite understand is where you want to go from what you repeat again and again, point
