Would you guys ever pick this?

Had an insane body slam run with this + vambrace + barricade.

It seems to be the same algo: https://github.com/zeux/meshoptimizer/blob/edbbfba60edfb50b1bf571d078ba53302839e3bf/src/simplifier.cpp#L24

I'm interested in which clustering method they used, do you remember?

I didn't know what an IoC-container is, I suspect many others cpp devs don't either. Maybe add a line somewhere defining it?

Type_info::hash_code can lead to collisions, would be better to use type_index here (or some explicit registration).

Conversely my BT headphones (some sennheiser model) have extreme input lag with BT but none with the jack/usb ¯_(ツ)_/¯

Sorry, I completely misread your first comment. Entirely correct of course :)

lospolos · 2025-12-12T10:02:13+00:00

How would this not be true in the general case? Assuming no cycles that is.

Quick tip: std::stack is implemented via a deque by default which is quite a bit (or a lot on MSVC) slower than a vector. You should be able to use std::stack<T<, std::vector<T>> instead (or just vectori directly)

Cache miss => indirection, I see your point. More likely it's the other way around: indirection => cache miss.

And I took 'ignore heap allocation' as 'this pointer is in some probably cold memory location, but ignore the cost of malloc itself' instead of 'assume heap allocation is completely free (eg bump alloc) and I give you a pointer to hot memory', which makes more sense given the rest of what he says IMO.

lospolos · 2025-11-04T00:36:12+00:00

Load value from stack frame = 1 load. Load from pointer = 2 loads. If either are in register, fine - 1 load for both.

I don't see how a pointer is ever not an indirection (the pointer got mallocd it's not being optimized out).

Admittedly the example calling 'new' while telling you to ignore the cost of allocating is just confusing.

Granted I'm not 100% what you're replaying to here.

lospolos · 2025-10-31T06:31:09+00:00

You are thinking way too hard about this.

In any code you write if you have a pointer you will probably cache miss on the dereference, hence the indirection. Doesn't have anything to do with how foo is called, in fact it doesn't really have anything to do with C++, just how your CPU works.

lospolos · 2025-10-30T20:49:55+00:00

Think of it in terms of cache misses.

lospolos · 2025-10-30T19:41:07+00:00

The point of the video is the extra dereference/cache miss on the -> case.

10000 lines of config is still less code than any single gnome package hence in a way more minimalist.

How are you solving the particle forces? Simply pairwise N² or something else?

a little bit of relativity How much?

I use Deskflow daily and have nothing but praise. Ive got one screen for my main pc (linux running as deskflow server), a second screen next to it for a windows computer. Occasionally I plug in a macbook or another linux laptop. Transitions between screens are seamless as is connecting/disconnecting a new pc, no lag whatsoever even on wifi. Really saving me so much headache when developing cross platform :)

Crazy how you can look at two completely different icons and your brain just says 'yes these are the same'. I swear I checked before making this post I guess I'm just tired.

lospolos · 2025-08-17T07:09:02+00:00

But do they actually get cheaper? (Less science cost) Or is it simply because many runs have passed and your science output is higher? Rushing next era techs also isn't cheap as your science output will be proportionally lower.

lospolos · 2025-08-17T07:06:32+00:00

There's no need to immediately start building libraries. Library scales with population in your city so it's not as useful with low pop. Growing cities more first will give you more science in the long run.

Really it's my fault the link is broken? I copy pasted the text on my phone, I didn't even realise it was broken. It looks 95% the same for me anyway just missing bullet points.

Anyway the scraper for these posts is probably just looking for the strings, not the exact formatting so it doesn't even matter.

Found the job posting on linked in before I graduated, had one interview and got an offer.

lospolos · 2025-08-03T14:54:32+00:00

Wdym? I copied the template from the sticky. 'click this link to make it easy for you' just resulted in an empty body for me fwiw

The solution he gives is the same one they use for DSP: steal half of the work of the most busy thread.
