Am I missing something? He says PC Magazine fired him because he was critical of his 5G article and that rankled the magazine's sponsors. Who specifically are the sponsors he's thinking of? Is there any evidence whatsoever that

While I get that this discussion is taking place in the context of contentious CoC debates in other projects, what I don't understand is why this is a big deal in the Linux case. Yes, people have been complaining about Linus' occa

Similarly, I spent 8 years building research and production trading infrastructure for a trading firm. The quality of data, tools, and trading execution infrastructure produced for these purposes was so far ahead of anything I could access

I'm not a lawyer, but this definition can't possibly be correct, can it? If you're a janitor and you come across a piece of paper or a conversation between bigwigs discussing a merger and sell it to a trader, the trader and t

At least in my limited experience, matrix multiplication optimization is some combination of a) so specific to the specific matrices being used that the optimization amounts to finding "tricks" to reduce the problem (dgemm to sgem

We're now well out of my knowledge base, but your comment certainly makes things interesting. If they have similar NUMA latencies (big if!), I guess maybe the edge would go to whichever chip had higher NUMA bandwidth? Just sort of thin

I wonder if there were NUMA effects at play since the Intel server was dual-socket and the EPYC was not. It's not entirely surprising that a CPU-heavy workload reading from filesystem cache (i.e. memory) could cause a substantial amoun

What specific quantitative reasons do you have to suggest a questionnaire is not appropriate for this type of study? Did I miss some other study somewhere that suggests a questionnaire can never produce good science?

That to me read more as CNN getting someone uninvolved in the research to give a quote that makes for good copy. I agree that it's not a particularly useful thing to say, but it's important to note that Collins is not involved in

Given that Stanley just said precisely the opposite, I'm wondering why you made this comment. I'm not being a jerk, but I wonder why you spoke so authoritatively. Do you think that he's lying, or were you just speaking in gen

I wondered that as well. I guess my imagination for uses isn't particularly good, but all the uses i bought my 16 core workstation for (mostly research computing development) would really suffer with the memory performance of the 32 co

I dunno, maybe. They're so completely different that it seems extremely unlikely to me that anyone will confuse the two in a conversation with any context whatsoever. The conversation you made up would almost certainly start with a dis

If it makes you feel any better, there was no particular shortage of idiots there either, just like any other place.

I worked at one of the above and can confirm that the interns, particularly the R&D interns were producing truly excellent work at the forefront of their respective fields, particularly with the mentorship of the senior staff. I'm

I'm not sure what better to call it. Charm++ (its core) was around ruining the lives of chemistry grad students and their sysadmins long, long before pycharm was a twinkle in its creators' eyes. I'm sure jetbrains won't

I’m in the same boat. I’ll be moving from the US to the UK shortly, and my options for what to do to keep my US number (and keep it functional while I’m in the UK) are pretty limited outside of google voice. Especially since, as you noted,

In general, I'm pretty happy about this. The more I used Atomic Host, the more I liked it. While it was a pretty dramatic departure from Fedora's dnf/rpm world, I really like how rpm-ostree handled the Atomic update/roll

Yes, they announced at the Red Hat summit that they'll be phasing out development of rkt, though of course will do nothing to stop outside development. Between docker and cri-o, I think they decided that the need for a third supported

It’s still a bit iffy. The lack of a proper S3 sleep state is a big, big problem for me. I lose about 6% of the battery life an hour in sleep on F28, and it generates enough heat that I don't feel comfortable putting it in its sleeve w

The DOE (and DOD, but with whom I’m less familiar) tends to spread out these purchases over multiple vendors to keep multiple US-based providers able to build and support these machines (and I imagine to keep costs competitive). The last fe

This seems pretty cool in principle, but I got as far as a single nonreplicated MDS before I lost interest in trying it out at this stage. Admittedly, my background is in HPC where metadata performance and reliability requirements would pre

I mean I don’t really want to argue about it because it seems like a silly thing to argue about, but just because you aren’t interested doesn’t mean nobody else is. Here’s a thread from the November list: https://news.ycombinator

People steal technology because someone else’s is better and it’s cheaper than doing the R&D yourself. If the US just quietly made better computers and there was no ranking, I’m certain China and Russia would still be stealing IP.

Just a point of order: Summit isn’t used for weapons work. You have to go down to 6 and 7 on the current list to find one that is. The DOD stopped reporting many of their computers to the list though, so it’s anyone’s guess where those woul

This competition has been going on quite a while. Is there any evidence it has led to any of that?

The rankings come out every June and November. They’re always talked about here because big computers are really cool.

The labs and supercomputer manufacturers also need this narrative to get continued funding from Congress. I spent many years in DOE supercomputing labs, and there was a heavy emphasis on competition whenever you wanted to knock loose a few

There’s no call to be so rude. The RH/CoreOS people here are acting in good faith, I think they’re being exceptionally helpful, and they don’t even need to be answering questions at all.

Thanks for the response! My immediate question after I read the article yesterday was on the future of Fedora (and RHEL) Atomic. Both you and the press release mention that CL will be supported for a while, but it's not clear what&#x27

The bits about the OpenShift integration are interesting I guess, but buried about halfway down is the news that they intend CoreOS' Container Linux to supplant their existing Fedora/RHEL Atomic Host, and Brandon Philips from Core
