caspper69··on Preview: IBM z/OS v2.5 [pdf]
Well, the last SuS/POSIX came out in 2008. It's 2021.

It should come as no surprise that since Linux has become the defacto POSIX standard that no other OS could keep up (or would want to really).

This is not entrapment, it is a honeypot.
caspper69··on RMS regrets not accepting LLVM into GCC during 2005 (2015)
I think it's fair. GCC made their decision many years ago. Even this email is 6 years old. Why post it now? Methinks because it fits a narrative that RMS is an ineffective leader that wouldn't know a good decision if it landed on his face.

I absolutely 100% agree with you.

But I am trying to decide if the internet brigade is upset because they think this person is guilty of more than they are letting on, or if they are guilty of extremely poor judgment, and the internet is never going to let them forget it.

I further wonder how long people can be punished for exercising extremely poor judgment, or at least making the wrong call when the optics are already extremely poor.

You seem to have a problem with the arrest / conviction timeline.

The father was arrested, hired, then convicted and sent to jail. It is entirely possible to believe one's friends & family after their arrest, but completely change your mind once they are convicted.

What am I missing here?

Edit: maybe you are unfamiliar with Western justice systems where people are able to post a bond and remain free until the verdict and/or sentencing phase?

This is a very serious allegation. She says she was in the house off and on, and it appears she had a complicated relationship with her father (this is not at all surprising given the context).

I am not saying it is not true, but it is pure speculation on your part, unless you were somehow part of the investigative team, and a very dangerous idea to just throw out there with nothing more than conjecture and circumstantial reasoning.

caspper69··on Over twenty subreddits have gone private
Well, minor nit here, the father was not convicted when they were hired.

They received 22 years when they were convicted, so unlikely to be working anywhere.

But who knows what the father told his child. I mean most reasonable people would not believe their parent capable of such horrors, even if they were charged.

caspper69··on Over twenty subreddits have gone private
The article seems to indicate that this person was not involved, and had no knowledge. They were also never charged.

I mean, the situation itself is quite horrifying, but I'm unclear as to why this should cause such an uproar. Guilt-by-association is already tough, but now guilt-by-relation? That's going to be tough the world around.

caspper69··on GeForce RTX 3060 Ethereum Mining Restrictions Have Been Broken
I was indeed referring to the RBS article, which as you mention was bunk. I read it in passing several months ago. And it was $175 million they estimated, I must've crossed wires with the recent $1B shareholder suit.

Thank you for making me do a little leg work. Perhaps I should have done that in the first place.

caspper69··on GeForce RTX 3060 Ethereum Mining Restrictions Have Been Broken
It is my understanding Nvidia allowed cryptominers to pull up semis and load them up with GPUs in exchange for about a billion dollars.

My guess is this was accidentally on purpose (see also the recent shareholder lawsuit; Nvidia did win that one btw).

caspper69··on Valve's Proton Has Enabled 7000 Windows Games on Linux
I would have to assume that OP is lamenting the fact that the games themselves are not running natively on open source, and the existence of Proton detracts from game developers / publishers targeting Linux/OSS because now they don't really have a need to.

Or he could be lamenting that the games themselves are not open source, but I haven't heard many of even the most die hard OSS evangelists suggest that AAA gaming content should be open sourced.

Despite your feelings on the issue, the difference is quite stark. Relying on allocations in yearly budgets, subject to the political whims of lawmakers, is clearly a different animal altogether.

caspper69··on 70TB of Parler users’ messages, videos, and posts leaked by security researchers
I arrived at that conclusion all on my own. Something a disappointingly large portion of Trump supporters seem to be unable to do. And last I checked, the truth is that conservative media is a much larger slice of "the media" than it would have you believe, I mean, except when it touts its ratings to anyone who will listen.
caspper69··on Microsoft job posting suggests a major user interface update expected in 2021
It is my understanding that the biggest issue with Control Panel is 3rd party control panel widgets that would be incompatible with any wholesale changes. That may of course just be the official party line too...
caspper69··on I prepared for a decade to graduate in CS in three months
It is per credit hour. A 3 credit course would require 6-9 hours per week, a 4 credit course 8-12.
caspper69··on I prepared for a decade to graduate in CS in three months
My university recommends that you spend 2-3 hours on your own per credit hour of study per week.
caspper69··on I prepared for a decade to graduate in CS in three months
This is overly simplistic.

There are tiers to everything. If you think it's MIT or Harvard, and then everyone else is a tossup, I've got some very bad news for you.

caspper69··on I prepared for a decade to graduate in CS in three months
I have to agree here. I am going back to get a 2nd BS, this time in a technical field, and I just finished discrete mathematics (at a community college no less). We used Rosen, 8th edition, and I had single homework assignments with enough problems to fill up 6-8 hours if you include the readings required. It was probably one of the most challenging classes I've ever taken.

And then the proofs. Oh the proofs.

caspper69··on OSv – Linux binary compatible unikernel for virtualized environments
The biggest problem is that context switching overhead becomes the main "work" being done, rather than the actual work of the threads, for some core count n (which depends on workload).

You can already saturate an entire core just copying data from a NIC. Of course, enter BPF and all that jazz. Plus it doesn't play as nice with BIG.little multiprocessing (AMP - asymmetric multiprocessing).

edit: I should note I am not advocating getting rid of preemption entirely, because it is needed for at least one processor, but having a fixed quantum causing a context switch on application CPUs is highly disruptive, both from the operation itself, and from blowing the cache all the time. Incidentally, one of the main reason for green threads.

caspper69··on OSv – Linux binary compatible unikernel for virtualized environments
I love it. We spent 30 years getting preemptive-multitasking working, and it is such a giant fragile pain in the a, that it is easier to just virtualize the whole damn computer rather than making different software play nice together (maybe run well together is more apropos).

We have now come full circle. People want DOS.

I have officially lived "long enough." Not too long, mind you, just long enough.

caspper69··on Working from home at 25MHz: You could do worse than a Quadra 700
I have been toying with this idea for far longer than I'd ever care to admit. It works very well.

Preemption is evil in a multicore world. Still necessary in spots, but evil nonetheless.

caspper69··on Monads and GATs in Nightly Rust
I can relate to this 100%.

I'm working though a Rust course right now, and while my code works fine (once it compiles), I always see the reference implementations of the code, and it's like 2 lines of filter/map/collect, and voila. Meanwhile, my 8 line frankenfunction looks like the Charlie Brown Christmas tree.

caspper69··on How many GNU/Linux users are needed to change a light bulb?
You are correct, it is not necessary to specify every major user-space program. But with GNU/Linux, GNU is the operating system. In fact, there have been Linux distros ported to run on *BSD kernels.

It's more like this: the whole OS is GNU (the coreutils), minus the kernel (most of which is device drivers). That's why they do it. Or at least why there are those that are passionate about the naming.

Also the reason why, had 4.3BSD not been in legal limbo, we'd all most likely be using GNU/FreeBSD.

caspper69··on ARM and Lock-Free Programming
Thanks for the heads up on the reply.

And this is why I shouldn't critique year old blog posts before 6am, lol.

I still don't care for the way that section was phrased, but I have a rather pedantic background in telephony and serial ports.

My apologies.

caspper69··on Amazon EC2 Mac Instances
I think you are missing the point intentionally. You can't run those apps on an Apple iPhone, but I suspect you knew this.

It's ok to take the literal definition of the word monopoly and take it to its logical conclusion, I suppose. The U.S. government will not do that, however.

caspper69··on ARM and Lock-Free Programming
You reference a blog post on your Github (regarding the algo description). I believe the author of that blog (someone at Ferrous Systems) has a pretty significant misunderstanding of DMA and serial ports, which raises a whole host of other questions on down the chain <additional unnecessary comment removed>.

edit: I know it's not cool to complain about downvotes, but this is a legitimate concern to raise for this poster. I am not attempting to denigrate anyone here.

How about being the only way to even build an application for 50% of the U.S. mobile market?
