I think we have a quiproquo about the level of atomicity here. You seem to be talking about _application level_ atomicity, like when you issue 4 write() to a file and want an "all or nothing" flush of these 4 writes. I'm talk

> All filesystem operations on modern computers should be atomic Well that seems a bit over the top. You would pay the price of full consistency for every write, while just one write every 3 years will fail. It would be insanely slow and

Yeah, I just had a look and it seems BBUs don't actually power the disk. They just keep the volatile cache alive until the disk is powered to flush them.

I guess I've been living under a rock, because I had the souvenir that disks with volatile write caches did have a small power bank, able to sustain the disk for the few seconds it needed to flush its caches (what it called a BBU?) Whi

These paywall things are such a bane... I do have a registration at Bloomberg from work, but I get logged out of the website so frequently that it's basically faster to read from a paywall bypass. This is absurd.

I guess I still don't clearly see what the leading question is pointing at. Should that be: _why was it not important to optimize for vector pop front?_ If that is the case, then I feel like the overall philosophy of vector vs deque an

That is the exact opposite of my experience. I try very hard to have the database as dumb as possible. - Having mixed workloads on the database servers make it almost impossible to profile and tune. By definition, a database answers a lot o

by Galanwe 3y ago
I think it is precisely the point. What you suggest is basically a tradeoff for speed of front removal against wasting some memory. There are an infinite number of such subtle tradeoffs that can be done. Some line need to be drawn somewhere

Because there are an infinite number of half-breed data structures that you could think of to balance tradeoffs. The STL has to restrict itself to somewhat stereotypical data structures that are intuitive to understand, yet can be composed

I 100% agree with you. Early in my career, a senior colleague used to reply to complaints with the simple statement "you only get the company/boss that you deserve". By that, he meant that if you complained, you were always f

That's basically what I did the first year working with git. Then I met a coworker that told me to stop doing this and come with him on a whiteboard to understand and solve the problem. That was painful the first month, but after some

I don't quite get your point. A blockchain is just an infrastructure on top of which you run your business logic. In a sense, it's similar to what AWS would be in a centralised world. So basically, you can add whatever registratio

If it's just a driver problem, why not checkout the old one, build it as a new module with a different ID, and insmod it on the new kernel?
