@davepl1968 Grab DOSBox-X and an actual copy of Windows 3.1 and you could run the software with a VM that's the equivalent of a mid 1990s 486 with less resources.

I had a 70-year-old mechanic buddy that used a piece of 16-bit Windows software called "Machinist's Friend". He couldn't give it up, so I wound up running an entire XP VM on his new machine just to run the app. It took about 5 minutes to start! Sometimes the app is more important than the operating system!

@xsphi If they care, they probably hide it because of adults who would probably never take anything they say seriously anyway.

why are teenagers, as a class, so incapable of political self-defense? they're on the verge of losing access to large swaths of the internet, social media, and culture generally, and they... don't seem to care at all?

@A_Absol_Enjoyer @xsphi Here's a teenager that's not incompetent, in fact, seems pretty mature. Your broad stroke against all teenagers is wrong. Stop being so ageist against teens. x.com/lorahmoe/statu…

@A_Absol_Enjoyer @xsphi Have you considered how infantilizing it must be to a teenager to call them a "kid", like they're still a child?

@A_Absol_Enjoyer @xsphi Second issue is using "all teens are morons" to help justify keeping them off of the internet entirely, then saying that since >90% of internet usage is social media, and "nobody" ever visits anything off that list, that the internet is social media and therefore bad for you.

@A_Absol_Enjoyer @xsphi My main issue is that you think all teenagers are incompetent morons aka "retards" and I think that's far from true. Perhaps some lack life experience. Surely many are competent in something by that age and learning more by the day.

@A_Absol_Enjoyer @xsphi Facebook today is a popular place for old people to post about their old hobbies and share their stupid Minions memes 🤣 The younger generation left long ago.

@A_Absol_Enjoyer @xsphi Your own screenshot says it correlates with the advent of *social media*, not the internet. The internet is not social media. To make an analogy from the past, the shows on TV are not reality, even when "reality TV" became popular.

@A_Absol_Enjoyer @xsphi It would be healthier if a parent or guardian were to guide them in browsing the web and teach them what to watch out for, how to browse safely, do's and don'ts, than to just isolate them until they're 18 and then suddenly unleashed without a clue.

@A_Absol_Enjoyer @xsphi Adults are not teens, and teens are not kids. Are you proposing that teens should be shielded from the internet entirely because there are some bad places out there? If that's your attitude, then you shouldn't let them outside either because there's bad things IRL too.

@BrendanCarrFCC Ever wonder why they call it *The* View and not something that implies the show allows any other point of view? 😏

Disney has filed a petition with the FCC asking the agency to declare that The View is exempt from the statutory equal opportunities requirements that would otherwise apply to broadcast shows. Disney argues that The View qualifies as “bona fide news” under the law, comparing itself to Meet The Press or Face The Nation. Therefore, Disney argues, it can have one partisan candidate for office on The View while denying equal opportunities to all others. The FCC is now seeking public comment on Disney’s request to be labeled as “bona fide news.” Is The View a “bona fide news interview program”? Under FCC case law, tv shows do not qualify as “bona fide news” if their decisions are based on partisan purposes, such as an intention to advance or harm an individual’s candidacy. As the Public Notice observes, Congress originally passed the equal opportunities law to prevent media gatekeepers from deciding the outcome of elections. The law, even when it applies, does not prohibit anyone from having any candidate appear on any show. Rather, Congress intended it to empower voters with more information and encourage more speech. The FCC welcomes your views: docs.fcc.gov/public/attachm…

Do you see how they use the english language against us? WORD SYNTAX, WITH THE LETTER "T"

@kris06105858770 @sudox7 GCC's optimizer is smart enough to turn a generic C implementation of byte swapping into the x86 BSWAP instruction for i686 and x86_64 targets. Which is impressive. felixcloutier.com/x86/bswap

@sudox7 After compiling with optimization both variants result in exactly same output, e.g. gcc -O2 -march=x86-64 produces the following mov %edi,%eax neg %eax cmovs %edi,%eax ret In such basic transforms, better to write simple and explicit code and let compiler do its job.

your CPU hates if. a mispredicted branch costs 15-20 cycles. every time. there's a version of abs() with 0 branches that most devs have never seen x >> 31 arithmetic-shifts the sign bit across all 32 bits. negative numbers become 0xFFFFFFFF (-1). positive become 0x00000000 (0)

@sudox7 Use some ANSI escapes and you can make it colorful. www2.ccs.neu.edu/research/gpc/V…

i built an animated terminal progress bar in C \r moves the cursor to the start of the current line without going to the next line. the next printf overwrites what was there

@CryptoCyberia Windows 3.1, 95, 98, and XP. Retro DOS/Windows gaming would love it.

Microsoft could undoubtedly absolute BTFO Linux if they just open sourced Windows 7 and let the open source community fix it up for modern use. I honestly believe this, and it would be the distro I run 100%. Search your heart. You know it to be true. Microsoft should just do it

@lauriewired Back in the Win95/98 days you could write a Win32 program to use SGDT and SIDT to locate both tables, and then read them directly.

Is your software is running in a simulation? Trust me, sometimes you really, really care. There used to be a really simple, single-instruction trick in x86 assembly, affectionally known as “the Red Pill”. SIDT is an (unprivileged!) instruction that tells you where the Interrupt Descriptor Table lives in memory. On bare metal, the IDT sits pretty low. Early VMware placed its virtualized IDT in a very high address, to avoid the guest colliding with the host. Very easy check, IDT high = you’re in a simulation! Most consider SIDT to be an actual flaw of x86 architecture design. In computer science terms, it fails the Popek-Goldberg test. Intel engineers didn’t anticipate the security risk in the 80s. The single instruction redpill doesn’t work anymore, hypervisors are way better now. We’ve got extra ring levels, multiple cores, KASLR, you can also trap + lie. But it was fun while it lasted! Of course, modern “red pills” are very advanced; anyone who’s worked in reverse engineering, malware, anti-cheat, DRM, (maybe timekeeping too?) is intimately familiar with VM detection. I’m curious if there are any other fields that very strictly check for emulation.

@MarekKnapek @straceX Apple learned that lesson the hard way when the 68k went from 24bit to 32bit addressing en.wikipedia.org/wiki/Classic_M…

most x86-64 linux user-space pointers only use 48 address bits. some runtimes temporarily store metadata in the upper bits, then mask them out before dereferencing the pointer again. this technique is called pointer tagging. lisp runtimes, garbage collectors, and JavaScript engines use it to attach extra information to pointers without additional memory overhead.
