Cypro-Minoan syllabary
The Cypro-Minoan syllabary (CM), more commonly called the Cypro-Minoan Script, is an undeciphered syllabary used on the island of Cyprus and at its trading partners during the late Bronze Age and early Iron Age (c. 1550–1050 BC). The term "Cypro-Minoan" was coined by Arthur Evans in 1909 based on its visual similarity to Linear A on Minoan Crete, from which CM is thought to be derived. Approximately 250 objects—such as clay balls, cylinders, and tablets which bear Cypro-Minoan inscriptions, have been found. Discoveries have been made at various sites around Cyprus, as well as in the ancient city...

in a few years some codepoints may be filled with babylonian scripts or something
qwr
Feb 17 15:49
technically all the code points are "valid", just some are unused currently
qwr

@Themoonisacheese it should not be too difficult. I am only checking if the codepoint encoding is valid, not if it is mapped to anything.
qwr
Feb 17 15:03
@Themoonisacheese there are many challenges that have builtins. obviously they are discouraged. I believe the actual code needed can simply be a state machine on the byte string.
qwr

is there a challenge for just determining if a bytestring is valid utf-8 or not?

all the weird pipes I listed are not in base R
qwr
May 25, 2021 21:52
people rarely use them
qwr
May 25, 2021 21:51
there's also right assignment like x-> y because why not
qwr
May 25, 2021 21:50
the assignment pipe is like foo <- foo %>% bar is written as foo %<>% bar
qwr
May 25, 2021 21:50
they actually used the letter t
qwr
May 25, 2021 21:50
there's also a tee pipe %T>%
qwr
May 25, 2021 21:49
%<>% is an assignment pipe which does a pipe and assignment

I wrote a simple python program of cubic time complexity to check up to n=1000 and didn't find any. It's quadratic time per row as it computes (n choose i)^2 and then does basically a small subset-sum. Edit: exactly what @Sil did. Fellow Project Euler solver...

@tofro the x86 string instructions only operate on strings in terms of comparing two memory addresses and incrementing a pointer, so more like arrays

And just because it isn't scientific when it's first conceived, doesn't mean it can't become testable in the future with new ideas for experiments or new technologies.
qwr
Jun 18, 2024 08:57
@DikranMarsupial interesting you bring up string theory because a lot of physicists don't consider it scientific. Continental drift would be scientific when it was first proposed if there were empirical tests that could be done. And idk if I'd call eternal inflation scientific as it's currently an untestable model. The best you can do is assume the future will be like now and extrapolate very very far.

@DikranMarsupial what things are obviously science that aren't falsifiable?
qwr
Jun 18, 2024 08:57
@Miss_Understands I don't understand what you're trying to say. String theory is precisely unscientific in the Popper view because it is not falsifiable.
qwr
Jun 18, 2024 08:57
@DikranMarsupial how co you even define causality? This answer fits best with the Popper view of science as falsifiable claims.

@PeterCordes I posted a simple example just skipping even numbers, yet it seems to perform just as well as this complicated sieve. I can't guarantee the benchmarks are done correctly but the timings look about the same.
qwr
Aug 25, 2022 13:10
@PeterCordes by standard sieve I mean a direct implementation of the Sieve of Eratosthenes without any small prime optimizations. I didn't consider segmented sieve for simplicity and because everything here fits into RAM (the paper goes up to N=2*10^9) but maybe segmented would actually help for cache reasons or something.
qwr
Aug 25, 2022 13:10
@AhmedDiab there are a lot of floating point operations I can see compared to the standard Sieve of Eratosthenes. If you'd like I try to run some benchmarks against a simple implementation.
qwr
Aug 25, 2022 13:10
If you eliminate multiples of 2 and 3, doesn't the normal Sieve of Eratosthenes already do this?

The answer assumes the attitude against migrants has to do with multiculturalism. It is possible it has nothing to do with culture, but economics of the workforce or local migrant policies.

Being anti-migrant is not the same thing as being against a race. There are many dimensions to migrants, including economic and political, and migrants aren't even one race or ethnicity.
