I like the Univers-like font on this page.

Also, the € symbol is a suffix to amounts, not a prefix like $.

4chan is more moderated than you'd imagine.

Is this a common thing? When I was in school the timetable was printed on paper and applied for the whole term. What are these substitutions and changes and why do they happen frequently enough to need daily updates?

Does the kid have to memorise this in the morning so he knows why rooms to go to?

I don't even think my parents were aware of my school timetable. Why would they be? That was my business. It seems a bit weird to me that parents get involved to such an extent.

> Could the protocol have been better designed to resist this local cloning attack?

I don't see how, the attacker is cloning the secrets used to sign the request, if they have those secrets there's no way of distinguishing the clone from the original device. The whole security model of secure elements is preventing the keys from being extracted, if you can do that there's no more security than saving the key to a file on your computer.

Of course to get the key they need to physically open the device, so unless someone actually takes your key it's more secure than saving them on you computer.

I get a 404.

And I also get blocked on the cloudflare link for some reason.

most emoji are banned, as are nonstandard space symbols like thin space and some other things. emoticons (things like :-) and XD) are allowed. generally alphabetic characters and digits are allowed, and some other things, but i think unknown unicode is forbidden by default. https://news.ycombinator.com/item?id=23440551 has some investigation and results which are probably still accurate

i do most of my algebraic formulas with the compose key and a custom compose map mostly written by mark shoulson https://github.com/kragen/xcompose

for the above, after a false start picking random unicode characters, i realized that maybe i shouldn't use a modern language because someone who actually uses the language might feel like i was calling them an extraterrestrial, so i switched to googling archaic scripts. i pasted part of the old permic table from wikipedia

    >>> s = '''𐍐‎    𐍑‎       𐍒‎       𐍓‎       𐍔‎       𐍕‎       𐍖‎       𐍗‎       𐍘‎       𐍙‎       𐍚‎       𐍛‎       𐍜‎       𐍝‎       𐍞‎       𐍟‎
    ... U+1036x     𐍠‎       𐍡‎       𐍢‎       𐍣‎       𐍤‎       𐍥‎       𐍦‎       𐍧‎       𐍨‎       𐍩‎       𐍪‎       𐍫‎       𐍬‎       𐍭‎       𐍮‎       𐍯‎
    ... U+1037x     𐍰‎       𐍱‎       𐍲‎       𐍳‎       𐍴‎       𐍵‎'''
    >>> print(''.join(c for c in s if ord(c) >= 0x10350))
    𐍐𐍑𐍒𐍓𐍔𐍕𐍖𐍗𐍘𐍙𐍚𐍛𐍜𐍝𐍞𐍟𐍠𐍡𐍢𐍣𐍤𐍥𐍦𐍧𐍨𐍩𐍪𐍫𐍬𐍭𐍮𐍯𐍰𐍱𐍲𐍳𐍴𐍵
    >>> len(''.join(c for c in s if ord(c) >= 0x10350))
    38
    >>> permic = (''.join(c for c in s if ord(c) >= 0x10350))
    >>> ''.join(random.choice(permic) for i in range(5))
    '𐍨𐍓𐍰𐍚𐍠'

and then i tried out the hieroglyphs range

    >>> print(''.join(chr(i) for i in range(0x13000, 0x14000)))
    𓀀𓀁𓀂𓀃𓀄𓀅𓀆𓀇𓀈𓀉𓀊𓀋𓀌𓀍𓀎𓀏𓀐𓀑𓀒𓀓𓀔𓀕𓀖𓀗𓀘𓀙𓀚𓀛𓀜𓀝𓀞𓀟𓀠𓀡𓀢𓀣𓀤𓀥𓀦𓀧𓀨𓀩𓀪𓀫𓀬𓀭...
    𓿦𓿧𓿨𓿩𓿪𓿫𓿬𓿭𓿮𓿯𓿰𓿱𓿲𓿳𓿴𓿵𓿶𓿷𓿸𓿹𓿺𓿻𓿼𓿽𓿾𓿿

but realized that most of them were unassigned, at least in my font and probably in the current unicode standard (in case someone discovers a new hieroglyph), so i just did this

    >>> hiero = (''.join(chr(i) for i in range(0x13000, 0x13100)))
    >>> ''.join(random.choice(hiero) for i in range(4))
    '𓃾𓂃𓂌𓀩'

you can do all this in python in termux on your phone too (you'll probably have to install it from f-droid) but it's a bit clumsier

it's funny how this conversation has swung from the extreme of universal constants of the universe to the opposite extreme of completely arbitrary and historically contingent things like which ideograms (themselves completely arbitrary) are prevented from being posted by implementation bugs in hacker news
