> Would you rather handle 1000 request per second or 1? Would you rather like to approach this problem by optimizing memory layout which, let's be honest, tends to give you more in the region of 1-10% improvements…
Maybe you shouldn't be doing O(n^2) inside a request handler in the first place. This has nothing to do with caches. And even if you do quadratic operations in your handler, how often do you write a new such handler?…
How many of your structs does your code access million times a second? For most programs, that number is firmly 0. While you are optimizing your struct layout and decrease you app start time from 1.122765 seconds to…
> Sometimes you have some very very high-use variables, with multiple threads each having one and writing to it often. And how often do you actually write such code? Most people: Between rarely and never. You write…
The central myth is that the average programmer should care. The typical programmer should treat CPU caches as what they are designed to be: mostly transparent. You work in a high level language and leave the tricky…
This is insane: > We demonstrate the application of video-based cryptanalysis by performing two side-channel cryptanalytic timing attacks and recover: (1) a 256- bit ECDSA key from a smart card by analyzing video…
Honest question since I don't really know how reddit works: Why can't reddit just forcefully re-open the subs that have been taken private? Mods are using powers given to them by the platform and I don't get why they…
> We have a long way to go before we can par ourselves on the back and claim to truly understand what’s going on. This is a misconception of scientific endeavour in general and of physics in particular. All models are…
The youtube link is David presenting his work that he describes in the originally linked article. One of the legendary presentations in CCC's history.
"Hard working" and "smart" are very different things. One could almost say that not being smart requires you to be harder working. (At least that's what I'm telling myself to keep working hard.)
Elon dropped out of openai because of differences regarding direction and conflicts with what Tesla is doing. He then secretly started developing sth similar and asked for a.moratorium on research+dev so his secret…
First sentence he claims he invented sth a long time back, but it definitely has prior art. I stopped reading right there. If everybody did that then perhaps he'd learn to be able to express things without immediately…
