Just curious, but is there a reason why you didn’t just use a single lock-less queue? Per-thread work queues sounds like a perfectly serviceable solution but I can imagine it an advantage to hide that added complexity behind a lock-less que

I don't understand why Tesco couldn't just start some pilot in a handful of stores, iron out the kinks, learn about reliability problems etc. and only after that decide whether or not to roll out the tech in all stores. That'

Using hashmaps by default isn't usually about raw performance for some small N, but to ensure your algorithm doesn't blow up if someone decides to take it out of context some day and dramatically increases the N (this is especiall

Developing a state of the art wafer scanner for EUV lithography would probably take decades, many billions of dollars (not tens but more likely closer to $100B), violate thousands of patents and the end result would 100% be inferior to what

Apples and oranges, Delphi != C++, and on top of that I don't think you really want to make the argument that the Delphi IDE can do all the things CLion can do for C++. I fondly remember my time writing Delphi, but I'm not jaded e

It's not the editor part that uses all this RAM I suppose, but the code parser and indexer that by default includes scanning & interpreting all your dependencies (system headers, boost, other third-party frameworks). There is a cla

One thing I've found with CLion is that you really, really want to edit the JVM settings for the IDE. By default it starts with a 2GB memory limit for the JVM, which even for small projects will severely drag down performance, e.g. my

I wanted to say exactly that. I've never been a big fan of vim plugins in IDE's, even though I still prefer them over no vim bindings. The VS code or Eclipse vim bindings are 'not great' at best, for example. But CLion +

They are not harder to predict or control than garbage collection, and have the benefit of being completely deterministic. Of course you can always come up with some pathological case that would trigger a 'deallocation avalanche',

Languages like Swift and Objective-C hide the reference counting for you, so 'instruction pollution' is not really something I care about. The overhead at the instruction & memory level is fairly minimal for these language too

True. This is why any serious game running on a VM with GC would avoid any kind of per-frame memory allocation and use arena allocators instead. The whole premise of a GC to save you from thinking about memory allocation is moot if it comes

Yes it's awesome! Calling it just a 'traffic simulation game' is probably a disservice to the potential applications of something like this. Very inspiring!

I’ve always thought of the Zachtronics game TIS-100 [1] to resemble programming an extremely simple transputer. Definitely worthwhile to try the game, if only to find out about all new kinds of problems you run into if you have to distribut

Quadratic complexity causes the runtime to grow quadratically ;-) - Quadratic = x^2, e.g. 0,1,4,9,16,25,36,49,64,81 - Exponential = n^x, for example 2^x, e.g. 1,2,4,8,16,32,64,128,256 Already very bad for small x even if n=2, but for n high

Can you explain why 'super strong windows' is a useful feature to have? I've never owned a pickup so I wouldn't know, but do the windows regularly break or something? Never happened to any of the cars I or anyone I know

Yes I get it, that's what I try to do as well. Just recently I went through the hassle of repairing my moms 5-year old Asus Zenbook, which had a broken SSD that was also a lot more effort to repair than necessary because of the non-sta

Reduced ad absurdum I thinks that is pretty much how it works. There is an acceleration structure that is traversed for each ray, to reduce the search space for ray-geometry intersections (probably a bounding volume hierarchy of some sorts)

Why is that? I’m not a battery expert but it would seem all that charging a battery does is move electrons in the cells around, no?

It would be interesting to split out the results between regular bikes and electric ones, now that they are becoming very popular. On an electric bike, distance is much less of threshold for choosing bike over car, and e.g. weather or ‘amou

Interesting, I didn't know that. But if you look at it purely from a cost perspective, it's at least a lot cheaper have the airpods swapped for 2x $49 when the battery dies, compared to buying a new pair with case for $199. Obviou
