rjmccall posted:m:n threading is when the language gives you an explicit thread abstraction but it's just not implemented 1-1 using lower-level threads. typically this is because the language believes, probably with good reason, that its threads are much more lightweight than the lower-level threads To be fair I'm mostly aware of m:n threading in the context of Unix and Posix threads. The theory here is that userspace thread switching is nice and fast (no system calls!) but it can only take advantage of one actual processor core; meanwhile kernel threads are expensive (context switches!) but can run on multiple cores. So the idea in e.g. Solaris and other commercial Unices and the very first attempts at proper Posix threading on Linux back in like the 90s was to have one 'real' thread per CPU more or less and schedule an arbitrary number of threads on the real threads using a user-space scheduler. Best of both worlds. Turns out doing this efficiently is way harder than people thought. Linux ended up just making kernel threads as lightweight as possible instead, and now even e.g. Solaris has followed suit in its latest versions; one Posix thread is just one kernel-level thread and it's all nice and simple.

eschaton posted:Pepperidge Farms remembers Green threads are cooperative threads effectively, I'm not sure what using MacOS's version of those instead would have brought to the table. Early Java on Solaris used green threads, too. If you want to have lots and lots of threads, they're a lot more lightweight than native threads, especially Solaris' back then, and if you don't have multiple CPUs/cores native threads aren't actually buying you that much. Also, can be easier to implement (on the one hand you gotta use async I/o everywhere, on the other your JVM/runtime/native code doesn't have to be native-threadsafe)

Xarn posted:What C gives you is a simple syntax (don't confuse this with simple semantics, or, god-forbid, simple to use language) to use for coding against a virtual machine that doesn't really exist and is, in fact, an attempt to codify the least common denominator of different CPU architectures. Treating it as a language that actually represents the underlying machine is laughable and a good way to get burned. Different CPU architectures as were common circa 1975, even

carry on then posted:are there any languages in production use that have or at least support keywords in various languages? To be honest, as I understand it it's pretty much expected that if you're a programmer, worldwide, to be any good you've got to know English - at least well enough to read it. Pretty much all the technically references, Stack Overflow, etc etc out there is going to be in English. At that point, having language keywords in English as well (and everyone worldwide being able to instantly understand what they're looking at in anyone else's source) is just kind of the way to go. I could see it being different for something like AppleScript that's supposed to be used by 'the common man' but anything above that? English.

Blotto Skorzany posted:why would macos lack strace? solaris (where they got dtrace from) didn't get rid of strace You mean truss, strace is some STREAMS bullshit from the early 90s there. All I know about dtrace is it doesn't seem to work with the output from my compiler (which creates statically linked binaries that don't link in anything, even libc, instead doing raw syscalls) buuuut my setup is old so I might not even have 64 bit dtrace I guess? and also obviously this is a hyper niche case. Similarly the Linux subsystem for Windows won't run the Linux output.

BobHoward posted:this is so true that, with modern transistor densities, when there’s a call for a state machine that’s complex but also needs hard real-time guarantees, chip designers often throw in a whole embedded CPU core and have a software engineer implement the state machine instead. every modern gpu or cpu or cellphone chip is sprinkled with dozens of cortex-M0 class microcontrollers. these are often not even touted in marketing materials since they typically cannot run user supplied code. they’re just testament to the difficulty of using hardware design techniques to solve complicated problems. Truth and also literally my previous job. Makes things much more flexible than hardware too since your M0 can potentially talk to and be configured by the host driver. An M0 is a fraction of the full size on die of modern chips, like a tenth of a millimetre squared or something.

Hmm. While GDI was indeed intended to be usable such that you could open a graphics context on a printer and draw on it as you would a screen, adjusting for DPI etc - that isn't the same as 'using the PostScript imaging model', that's just device independence. Indeed you will struggle to see a Bezier curve anywhere in classic GDI, X11 or QuickDraw, it's all your usual straight lines, rectangles, pixmaps and bitblts. Outside of fonts I guess but that's hidden from the programmer and early fonts were just fixed size bitmaps in any case. That's why Display PostScript was such a fancy high end big deal in the 90s, because now you could do all this stuff in your GUI (if you happened to be loaded and own a Sun workstation running NeWS or a NeXT box) feedmegin fucked around with this message at 15:26 on May 10, 2019 |

necrotic posted:.net core is becoming the main .net with v5 ' Taken together, the .NET Core and Mono runtimes have a lot of similarities (they are both .NET runtimes after all) but also valuable unique capabilities. It makes sense to make it possible to pick the runtime experience you want. We’re in the process of making CoreCLR and Mono drop-in replacements for one another. We will make it as simple as a build switch to choose between the different runtime options.' Uhhh why not just pick one and integrate whatever from the other?!
