  • I have heard of lighters with cosmetic colours! I think Hacksmith had (or has? Unsure if it was a limited time event or not) little bits to change the colour of their mini lightsaber lighter.

    I was thinking more functional usecases for it though, yeah. Like you know that A equipment is certified to do B thing (heating or something, idk) because it has this colour of fire, or it’s used to show that this fire is a specified temperature (for specific applications that need it, then you can just say the distinct colour of fire vs “reddish”, “whitish”, and “blueish” flames)









  • It’s a math pun that I came up with.

    explanation of pun

    In maths, “translation” is when you move an object in space. It is one of the transformations (like rotation and scaling).

    The other, more widely known use of “translation” is to convert between languages (in this case, from French to English).

    The math teacher interprets “translation” with the maths definition, and moves five steps. Abstract units (like “steps”) is common when you are learning the transformations in school (e.g. Alice moves 10 steps to the right, the point X moves 5 units in the southwest direction)


  • Wait, Asperger’s is considered a bad term? I did not know that as someone originally diagnosed with Asperger’s syndrome myself (but I did understand that it became incorporated as part of the spectrum).

    Doing a bit more research, looks like it’s because of its origins in WWII Nazi Germany (and therefore being linked to eugenics, white supremacy, etc., the idea that these people are better than those people). Dang, I definitely did not know that. I will try not to use it then.





  • The night time sky is not the same as the constellations above you will look different. It’s difficult to tell, especially if you live somewhere with a lot of light pollution, but the night sky does change. If you are near some place rural where the sky is clear, check it out! It’s pretty neat. Hell, the ancient peoples (Greeks, Chinese, Romans, etc.) wrote mythos relating to how the constellations, perceived as gods, appear and disappear depending on the season.

    Fun fact, there are some constellations that are never visible to those in the northern and southern hemispheres, especially when you go near the poles.



  • gassed the theater. With hundreds of innocent members of the public inside

    That’s terrible! And just double-checking with a bit of searching, yeah, this was a real incident. Whether it was “staged” is unclear (not enough evidence to support or deny it due to the lack of an investigation). But the Russian authorities did indeed release a noxious gas into the theatre without any sort of evacuation or coordination with health services, yet the official report by the Kremlin hails it as a success even though over a hundred people died?! I feel like, staged or not, that is something that should be criticised.

    For a bit of context, Russia was invading Chechnya, which declared independence after the dissolution of the USSR, and a Chechen militant group took over a theatre and held everyone in it hostage (how they did that, I’m not sure. Some of the sources blame it on negligence of Russian intelligence, or suggest that authorities in the area were bribed). There was a siege of the theatre, and by the second day, people started to get shot. Afterwords, the Russian special forces gassed the theatre before entering it in an assault, and most of the hostages, as well as the Chechen militants, were killed. Additionally, authorities in Russia did not say what the gas was, meaning the people administering first aid had to guess, causing more death and permanent injuries than was necessary.
