  • 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 term “vegetable” is a culinary term, and squash is prepared like a vegetable. For another example, tomatoes are fruits but are prepared like vegetables. Squash and tomatoes can be both fruits AND vegetables. This is my position on the “is X a fruit or vegetable?” issue.

    I mean, the idea of a “vegetable” isn’t a well defined group of plant parts like fruits are. Vegetables are a mix of seeds, roots, leaves, stems, etc. all of which are quite different. It’s just “parts of a plant that can be cooked as part of a meal”:

    “a usually herbaceous plant (such as the cabbage, bean, or potato) grown for an edible part that is usually eaten as part of a meal also : such an edible part” according to the Merriam-Webster dictionary https://www.merriam-webster.com/dictionary/vegetable (similar definitions exist for other dictionaries, some highlight that vegetables are usually used to make non-sweet dishes)

    The TLDR is that vegetables are loosely defined as “plant parts that are used to prepare meals, usually non-sweet dishes” and is a culinary term rather than a botanical one like fruits can be. So an item (like tomatoes or squash) can be both a vegetable and a fruit, the former culinary and the latter botanically. They aren’t mutually exclusive.



  • 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.

    Personally, I am using Summit (installed with Obtainium, it is not available in F-Droid)

    I find that it works quite well and has a very nice user interface! Pretty customisable too.

    edit: Forgot to add, yes, Summit can be installed through the Google Play Store.

    In my opinion, Framework is more ethical that most in the industry. Think companies like Apple, HP, Dell, etc. who are generally quite anti-consumer. For example, Apple’s parts pairing and closed ecosystem, HP’s lockdown of their printers. There are plenty of more examples to look for, turns out humongous for-profit corporations driven by money like money go up more than happy consumers.

    Whether Framework “ethical” outright I’m not sure. They support right-to-repair and interact with the community more. They share CAD files of their products so that people can make their own accessories and such, they are working with many Linux distros to improve compatibility, etc. I personally find the backwards compatibility of parts of their devices really impressive. So definitely, more ethical than most.

    However, they, like a majority of companies, are not focused on improving working conditions in factories, they are not necessarily using fair materials, etc. Additionally, the support of Omarchy is problematic. In a nutshell, Omarchy is pretty much a preconfigured Arch that DHH likes. The controversy is that this DHH is an insane alt-right guy, anti-immigrant, transphobic, homophobic, white supremecist, all that. The direct support (particularly on social media) of Omarchy is seen as an endorsement of DHH, when you go to Omarchy’s website, DHH’s name is right there. This obviously isn’t a good look for Framework, and they hammered in the idea that they are a “big tent”, implying that they are okay with DHH’s views. Point have also been made that Omarchy is a very new distribution with a small userbase.

    Source I found in a quick search: https://gardinerbryant.com/the-omarchy-framework-thing/ (13th Oct 2025)

    Note that Framework is not currently sponsoring Omarchy: https://frame.work/blog/framework-sponsorships (I am unsure whether they originally did, or if was just the social media promotion)

    Other companies support their own fair share of far-right lunatics, but that doesn’t make it ethical for Framework to do so of course.

    edit:

    TLDR: Framework is not ethical, but I would say it’s more ethical than other companies due to their support for right-to-repair, interaction with the community, and transparency on their sponsorships. It’s not a nice world out there, but Framework is one of the better ones.



  • In Hong Kong, the coins have different size and shaped ridges so that people with vision impairments can more easily distinguish between them! I remember the five dollar coin being big and round, the one was round and thinner too, while the two was more bumpy. And although the paper bill for $10 is more common now, the ten dollar coin was small than the other dollars while being quite thick.

    Many other countries have something similar, but I do like the HK coins personally. As a kid I always played around with them and sorting them by thickness, aligning their ridges (particularly for the $2 coin), etc.

    And indeed, none are sharp for the reasons you mentioned. Most coins have ridges though, as those are used to tell if some of the coin was sanded off for the metal.


  • My understanding is (and I could be wrong on some details, I’m no political scientist!), communism is a broad idea for the end goal of a society with no class boundaries, no private ownership, workers (or a representative for them, in some models) owning the factories/“seizing the means of production”, rights for all, everyone gets their fair share.

    There are many, very different ideologies for achieving such an ideal society. Additionally, different people have tacked on their own ideas onto it (such as the necessity of a violent or peaceful revolution, how to redistribute land, etc.). You can go from forms of anarchism (very anti-authoritarian) and democratic socialists (usually quite anti-authoritarian) to Stalin’s USSR and the Eastern bloc during the Cold War (very authoritarian with cruel dictators at the helm). Like most belief systems, there is plenty of infighting between various different factions.

    “Socialist” is another broad term and is usually used to describe groups, people, and governments that implement policies that will build up towards the communist ideal. It’s thrown around for many democratic groups as well as deeply authoritarian ones, hence the separation between authoritarian and anti-authoritarian communists that is very common.

    You might have heard of terms like “democratic socialist” and “social democracy”. The former are socialists who usually advocate for slow reform over a revolution, the latter are capitalists who implement socialist elements in their policies. Both try to uphold liberal democratic processes and are against one-party states like that of the USSR.

    TLDR:

    • “communism” is the ideal and optimistic goal for a state, people who pursue that are called “communists”. It is an incredibly broad term that can describe very different ideologies
    • “socialism” is used to describe groups that implement policies towards the goal of communism, people who support this are called “socialists”
    • “democratic socialists” are socialists who support liberal democratic practices and usually advocate for slow reform rather than violent revolution
    • “social democracies” are people who support some degree of socialist policies in order to make society more equal and fair while retaining the capitalist system
    • the separation between authoritarian and anti-authoritarian communism is very important! They are vastly different despite their shared goal of a classless society


  • It’s a reference to this image that has been shared in so many different schools around the world:

    Current (measured in amperes, or amp) is the flow of charge. emf (volts) is the energy supplied to a circuit per coulomb of charge (coulombs being the unit of charge. Current is coulombs per second). Resistance (measured with ohms) restricts the flow of charge (conductors have low resistivity, insulators are high. Resistance increases with length and decreases with crosd-sectional area)

    Ohm’s law is V = IR (or, with current isolated, I = V / R)
