For a work VR headset to work I think you need a couple of things. One is that it needs to be comfortable enough to wear for long periods of time. I usually get quite warm when wearing one. You also often end up with impressions on your fac

Usually std::unique_ptr or in a container like std::vector. Being too afraid of std::shared_ptr can lead to using references or raw pointers in the wrong places. That way leads to the usual memory safety issues.

The author claims that making better use of the cache hierarchy and programming in a data oriented way will improve perceived performance for users. This isn't where we should start though. Much of the time bad performance comes from e

DRY is much more than just not copying code verbatim. It's also about not defining the same logic or concepts in multiple places. This duplication can be a real problem since it introduces a very strong, hidden coupling between the dup

Is there really any challenge in making a roller coaster that kills its riders? Seems like the space of lethal coasters would be larger than for non-lethal ones. Also, is the short amount of time with hypoxia really enough to kill someone?

Take three somewhat flat stones to start out. Alternate rubbing the surfaces together in a random fashion. As you continue the high spots of the stones will be ground down and the surfaces will become flatter and flatter. In the end you can

Since the input fits in one chunk it’s hard to follow how it would work for larger inputs. The “chunk loop” is only executed for one iteration so it requires careful reading to see how the state gets form one iteration to the next. (Hint: i

Seems like n=3 really helps to get good results. With n=2 it was a bit hard to see that it actually followed the pattern.

It was shutdown because it isn’t needed anymore. The review times are usually short and the quality of crowdsourced data is lower because of this. https://daveverwer.com/blog/saying-goodbye-to-app-review-tim...

The Hawking radiation for a black hole with this mass would be really small. It actually decreases with added mass. So, this observation does not say anything about Hawking radiation.

This is correct, melting sea ice does not lead to a rise in sea level. It’s the melting of glaciers and ice sheets (on Greenland for example) that cause the sea level to rise.

I've been biking to work for a bit more than two years now. Same distance to work and not even any close calls with cars. I do ride quite carefully though and make very sure that they see me and stop before I ride out in front of one.

Bitcoin is mined using ASICs, and not GPUs. But, it’s true that mining using a raspberry pi would not be very useful.

> I was a little surprised at the headline, since I expected 'outperforms' to mean that it had better end-results, which is of course not the case. GP is just much faster due to it's relative simplicity and the results are

This is an absurd situation, having a military minder that tells you what you can and can't say in a production. It is hard to avoid some kind of interference if you want to borrow military equipment though. There is always some standa

It concentrates the sun from what I could understand from the article. Should work the same for any spherical bowl (parabolic would work even better) that is shiny enough.

James Grime (of, perhaps, Numberphile fame) made a video about it [1]. He also talks about how it's supposed to be related to Conway's game of life but is actually not (Conway's game of life is a 2D cellular automaton, while

Black holes move in the same way as any other object of the same mass, for example a star. When they merge they are typically orbiting each other already in a similar way to binary stars. When they orbit the system will lose energy to gravi

About this cutoff. I guess that it is an analogue to the phase transition we see in for example the Ising model (this example was given in the article). This transition is due to a change in temperature, i. e. the chance of flipping a spin

Sometimes the LED can be turned off even if the camera is on. But that may require some extra sneakyness.

Ok, so I installed it to try it out. Trying to get the WhatsApp widget running it seems like I must allow access to the camera and the microphone on my computer. This is ridiculous. On mobile, this is not needed, and is maybe even fine. Whe

Nice post about getting started with GBA dev. It is worth noting that to do anything serious on the GBA you need to use the tile+sprite modes for graphics. That is really the way to get decent performance. The way it done in the article is

Pretty neat visualization of the Lorenz attractor [1]. Also worth looking into are strange attractors [2], which are closely related to fractals. [1]: https://en.wikipedia.org/wiki/Lorenz_system [2]: https:/&#x2F

Now, I'm not a proponent of leap seconds. But I'm a bit curious to where the 7.389 m comes from? The earth rotates about 12 km along the equator in 26 s. Is the error of ~7 m for determining your position north-south wise? East-we
