Consider this (quite common) code: char buffer[LARGE_SIZE]; if(maybe_fill_buffer(buffer, sizeof(buffer))) { use_result(buffer); } The function maybe_fill_buffer() is an external library function that either fills the buffer

That's assuming you were reading it without writing to it. There are three common cases when that isn't true. The first is that you have a fixed buffer large enough for the maximum message size even though the typical ones aren&#x

It seems like what's missing here is lower cost plans, because the existing plans had been fairly affordable, but now they're basically triple. The least expensive one seems to be CPX11, old price $6.99, new price $20.49. That&#

by zrm 4mo ago
You made the claim that companies require apps because it has lower friction for ordinary users. That claim is in error. The implication that there is nothing anyone can do to improve the existing state of affairs is also incorrect.

You only need things like that for non-iterated games. A company that gets a reputation for keeping the money when it's a real bug would stop getting real bug reports.

You don't have to determine if it's an AI or not. If AI finds a real bug then it can get the bounty. If a human pays to make you read artisanal hand-crafted word salad then they don't get a refund. Real bugs get the bounty, i

Bounties already have that whenever you reject one for being nothing.

The noise problem is pretty easy to mitigate by choosing 2U servers instead of 1U. The latter are forced by the form factor to use smaller, higher speed fans. A bigger issue for enterprise hardware is that it's optimized for performanc

Its performance is pretty unbalanced. If you're using it for the couple of things that it's good at, the TDP is competitive.

by zrm 5mo ago
The original problem was that everyone runs copper instead of fibre because there are too many existing devices that only have copper. Running both everywhere would require you to buy and terminate twice as much cable as you expect to use

That doesn't solve the chicken and egg problem. What probably would is something like having PCIe and USB to 1Gbps fiber adapters that cost $5.
