It looks like I was wrong about UDP being supported by ssh. Sorry about misleading everyone. I've verified with nc that it doesn't actually forward UDP. I'm amazed that streaming media over this seems to work fine on most sit

[note I am wrong here - it doesn't support UDP - see below] The ssh SOCKS proxy supports UDP. I use Firefox with a SOCKS proxy via ssh (e.g. ssh -D 2222 hostname) to get around geoblocking and accessing papers via an institutional acco

One of the most interesting results here seems to be that the vaccine benefits from a long period between the doses, with the efficacy rising to 76% three months after the first dose, then to 82% after the 2nd dose. This seems to imply the

The vaccine basically would not exist without the UK government helping putting together the organisation to make this, before AZ even got involved, plus the academic research funding. This vaccine is sold at cost and is allowed to be manuf

This is in Iain Banks's book Transition. Did anyone else come up with this before him?

There are laptops with truly terrible cameras, in particular Dell, even in their most expensive laptops. These aren't my pictures, but I've tried different lighting but the pictures have the wrong colour, are low resolution and ar

I thought one needed Ctrl+L to refresh the screen when it gets corrupted by program output in "gdb -tui".

Me too... the lack of decent non-array containers is frustrating. The string handling is also painful (seemingly TRIM everywhere). I've also hit several compiler bugs trying to use fairly new features.

It's also commonly used in astronomy to measure the distance on the sky between two objects: https://en.wikipedia.org/wiki/Haversine_formula I could imagine these could be useful to be defined by computer librarie

I wish more games had better ways to reduce difficulty. There's a particularly obnoxious culture of purism in the gaming community, particularly for platforming games. People having difficulty are told to "get gud" or stop pl

Related question. I'm trying to sample something with no gradient information (messy astronomical likelihood computation). I'm currently using emcee which uses a Goodman-Weare sampler which breaks down with too many parameters. Ar

It was great. It showed that it is actually possible to run fast Python from within the standard interpreter with excellent compatibility. The only downside I remember was the memory usage.

Blake's 7 is an interesting old series with an arc and strong characters. You definitely need concessions with the special effects, though.

I think that's rather unfair. The measurements are still ongoing with ever-increasing accuracy. In 2018 they managed to record the closest approach of the star S2, measuring a velocity of 7000 km/s at its maximum. This was after m

Have a look at the linked documents giving the popular science background. They led the teams that gave the decisive proof that there is black hole at the galactic centre. The teams developed techniques to precisely measure the orbits of th

At least Qt cares more about compatibility: https://wiki.qt.io/Qt-Version-Compatibility - Qt 5.x.y releases are supposed to be binary compatible with each other.

It could at least prevent access to dot files or places where dangerous things could be dropped (e.g. ${HOME}/bin).

Qt. It supports Wayland. It can do high DPI scaling.

Yes - Fortan doesn't have a built-in pi constant, but does have trigonometric functions. Usually programs define pi based on atan or some other trig relation.

CPython had one as an external module, but unfortunately it's no longer maintained as PyPy was supposed to supersede it: http://psyco.sourceforge.net/ It actually worked quite well, though was pretty memory hungry.

I wish for better reviews and scores too. The animated reviews are simply awful. In some genres virtually everything has near 5 stars, even the most derivative badly written dross. I now ignore any positive reviews and look at the negative

One advantage of putting ssh on a non-standard port is that your logs, which are otherwise filled with automated ssh break-in attempts, now become almost empty. It's much easier to look for other problems when the signal to noise is in

Despite this, Germans seem to use a lot of bottles. Most German people seem to prefer to drink bottled water rather than tap water, even though tap water is of very high quality. They also don't have the concentrated drinks available i

I wonder if they've improved the screen hinges? I've given up on slim Lenovos as they had this weak metal bonded to plastic hinges which are easy to break through regular use. The screen snaps off the base and the case just gets b
