They mean fraud against them. Assume you rent a GPU to do PoW mining, using a stolen credit card, they can't charge you, but you have your coins and can disappear

The impact of IO_Uring on the overall design is really interesting Because it push you toward everything as async by default I can easily imagine node.js implemented on top of that, for example The move to async in modern languages also sup

That amount of money is not even a rounding error. And it is likely to be very obvious and public. You will crash the market, so can't really do that multiple times. And if you can Crack this there are better targets

The desire here is to avoid rebuilding a node if there is a single error in the disk no? Because otherwise, it would make sense to just bounce the node entirely and let it build itself from the replicas. As a database guy, the number of edg

The idea is that you make holding a lot of cash much harder to work with on day to day life. That means the incentives for that are far lower. It also complicate illegal activities in general. The idea isn't that your typical criminal

At which point you are probably guilty of "structuring". Which is a crime all on its own. Also, that only holds up until someone actually looks at you.

RavenDB has this feature, but it will also go ahead and create the relevant indexes needed on the fly. It is able to do so without harming production performance. See: https://ravendb.net/learn/inside-ravendb-book&#x2F

Unless I missed something, China just got the biggest wheat export in the world in its pocket (Russia). And the fifth is Ukraine. That means that food security issue is far less of a problem.

Transaction merging allows you to handle that nicely. By handling concurrent writes and merging them into a single write to the disk.

4% - 6% overall query time improvement? That is absolutely an actual problem that is very attractive to solve. You'll see database people jump through far bigger hoops to get much smaller improvements.

The linker can usually merge identical functions, and the compiler does this too. You'll only get different copies if they are relevant, and usually the branch elimination is more than enough to compensate. Another aspect about this is

Generally, really bad idea. Assume a 512gb RAM and most of that being in use. With a log file for durability. It sounds fine, but... What is the cost of restarts? You need to read through the log, apply it, etc. That can take a LOT of time

Something like this: struct cmp { hash: *fn(_:*void) u64, eq : *fn(_:*void, _:*void) bool, free: *fn(_:*void) void } With maybe some default options should be enough for at least the basics. Note that

Linked list has a O(N) search time, which is atrocious. A really common optimization is to replace a linear scan on a list with a hash table. In most languages, that is a trivial step to do, which means that it gets done. There isn't a

I think that there is a problem here with regards to what you are trying to do. You are conflating the _implementation_ of a hash table with the _existence_ of a hash table. You list a few problems: Computing the hash for arbitrary structur

The issue is _generic_ data structures, not external code. If I have to re-create a hash table for each scenario, I'll not invest the proper time to do so. So if I need a hash table to map inodes to strings and another to map strings t
