This is one of the books I recommend to my coworkers who are interested in operating systems - it teaches a surprising amount of things by telling you what an OS will do for you and therefore why you need it, instead of telling you how it

If you don’t mind developing, what made you switch stance ? many people never change their minds even when faced with overwhelming evidence , and based on your prior level of support, I’m quite curious about the actual process .

‘In other words: AI is making it possible to detect severe security vulnerabilities at highly accelerated speeds.´ Isn’t it rather : we now have a new family of security flaws detector, which find other issues on top of the ones already fou

Same thing here , but triggered by tiredness/stress. If I sleep a lot and well, then it somehow fades until I’m tired again. I assume my brain is somehow able to filter it out, unless it’s too tired/busy.

:-) never forget Occam’s razor ! No you were not abrasive at all - I’ve learned to assume good faith in forum conversations. In retrospect I should have started by giving the context ( march of 9s is a good description) actually, which woul

We’re in agreement. I think we diverge on ‘making it go away in my book’. When you’re the one having to debug all these bizarre things ( there were real money numbers involved so these things mattered ), over millions of jobs every day , ra

Well my admins eventually believed me , so I’m fairly comfortable with what I said. We also had a few thousands of physical servers with about of terabyte of ram each. You are right : we did see repaired errors, but we also saw (indirectly

by Agingcoder 7mo ago
I fully agree with you ! Neither soft nor hard memory errors, nothing… but but flips ,and reproducible at that. We scanned all our machines following this ( a few thousand servers ) and found out that ram issues were actually quite common,

It depends on what you bitflip. I once had a bitflip pattern causing lowercase ascii to turn into uppercase ascii in a case insensitive system. Everything was fine until it tried to uppercase numbers and things went wrong The first time I h

No it doesn’t :-) I’ve had plenty of servers with faulty ecc dimms that didn’t trigger , and would only show faults when actual memory testing. I had a hard time convincing some of our admins the first time ( ‘no ecc faults you can’t be ri

Optane was supposed to fill the gap but Intel never found a market for this. Flash is still extremely slow compared to ram, including modern flash, especially in a world where ram is already very slow and your cpu already keeps waiting for

Yes exactly. The kernel tries to guess as well as it can though - many years ago I hit a fun bug in the kernel scheduler that was triggered by numa process migration ie the kernel would move the processes to the core closest to the ram. It

by Agingcoder 7mo ago
Yes there are scheduling issues, Numa problems , etc caused by the cluster in a box form factor. We had a massive performance issue a few years ago that we fixed by mapping our processes to the numa zones topology . The default design of ou

My kids make fun of me because I know the shopkeepers around me by first name, along with the details of their businesses , and that shopping takes forever because I talk to everyone, customers included. I just love it, it’s easy and I get

This is very different Most random encounters have a pretext, from smoking a cigarette to talking to the shopkeeper, or being in a queue for a long time. Talking to a woman ( esp given that many of them are harassed from what I understand f

You virtually never bother them - worst case they’ll turn you down. On the contrary, they’re usually very happy to tell you about what they do.

The intonation is different, there are harsher sounds, but there are diphtongs everywhere in Dutch, and to me thisbis what makes it sound like English. French, Spanish, German etc don’t have diphtongs ( or they’re quite rare )

That’s what they do usually I understand - llm generates proof in lean, and proof checker proves.

A couple of days ago a colleague of mine was talking about very old rts games he still liked to play , and mentioned red alert. It turned out he had never heard of dune 2, Warcraft 1 and 2!

It has a very large number of bugs. My favourite one ( still happens ) is having to mute then unmute at the beginning of the conversation otherwise nobody can hear me. It was so common, with people fiddling with their headset, calling again

No it’s vastly different - give it a try first . Reverse debugging with full dataflow is magical. Interestingly enough, it takes a while to get to used to it since you tend to do things the old way, when the Pernosco, science fiction way is

Several things : immediately after 2008 less demand for exotics because clients were afraid of them, cutting costs rather than increasing revenue ( that’s industrialization with IT and standardization ) and more importantly, industry reachi

Im reasonably familiar with the exotics quant space. It’s essentially IT/data work - the days of sophisticated maths are mostly gone. There always was a lot of code, but these days for most people there’s little to no new maths. From w

These days a single machine with lots of ram and cores will handle almost everything you throw at it, barring specific compute intensive / memory bound scenarios ( current AI, gaming etc ).
