Most companies appear to be ditching plastic packaging for packaging which has a combination of plastic (mostly films) and card. The card now can't be recycled as the plastic content is too high and consumers are too lazy to separate t

Oh yeah they work fine when you neglect certain critical parameters. How hot do your solar sails get in Kerbal? And what is the maximum torque between the sail and the spacecraft in Kerbal?

The physics doesn't stack up for me. The spacecraft must be lightweight so it can be accelerated to high speeds but it must also have a very large area such that a large proportion of the laser photons hit it. This means a very thin di

std::sort is implemented using introsort [1] which trades off average case complexity for worst case complexity. If you are really chasing performance gains then these are the things you need to look into. [1] https://en.wikipedi

The claim "even 1 bit of bias on a 256 bit nonce value can be enough to attack certain cryptographic schemes" is true but there have been no practical attacks against 256 bit secured schemes. And the example of the mod 107 issue o

If you read the paper [1] I wouldn't say the data is convincing. The author's openly admit to changing the methodology of the data analysis (p-hacking) after the data collection. There are issues with data collection. Some data co

Printfs can be slow but their performance varies by implementation and may have no meaningful performance implications in many cases.

Address randomization helps but it's not enough. The phone still transmits at a regular cadence so it's pretty easy to figure out which old address has changed into which new address and keep tracking the same device.

30% stronger doesn't mean 30% less usage though so it would be interesting to see how much less concrete can actually be used in typical applications.

Whilst it is true there is no "correct" gradient, the author is making the reasonable assumption that the gradient can be simulated by two linear light sources (A and B) being shone onto a perfectly reflective (white) surface. Eac
