One very familiar pattern in AI and science right now is going from a lot of false starts on hard tasks (there have been near-misses where AI appears to solve an Erdos problem but just finds an old solution no one knew about) to actually doing the thing soon after.

Three Erdos problems in 3 days.

Much higher than the estimate death toll in the 2022 protests, and probably the bloodiest crackdown in the Islamic Republic's history, if you exclude the murder of political prisoners in jails in the 1980s.

BC "do Lula" passou metade do ano subindo selic de 12,25 pra 15 e a outra metade do ano mantendo em 15; segue indicando que vai ser 15 até pelo menos março de 2026. Mas tem gente que ainda acredita até hoje que o juro tava alto antes só pra atrapalhar o governo Lula...

Love this. I find it hard to think of ways to make compiler explorer better, but this seems like one!
matt.godbolt.org Matt Godbolt @matt.godbolt.org · May 23
Experimenting with something like this for @compiler-explorer.com - wondering what your thoughts are? AI is getting everywhere, and can be divisive. I'm hoping something like this - so long as I can get the output quality high enough - is a net benefit to help folks learn more about their code.
A screenshot of Compiler Explorer showing an "AI Explain this" view. The source code is: bool isspc(char c) { return c == '\n' || c == '\r' || c == '\t' || c == ' '; } The asm is: isspc(char): mov ecx, edi cmp cl, 33 setb dl movabs rax, 4294977024 shr rax, cl and al, dl ret Below is a "Claude Explain" window with: The function isspc(char) is compiled to an efficient bit manipulation technique to check for whitespace characters. Let's break down the assembly instructions: mov ecx, edi Copies the input character from the edi register (first function argument) to ecx cl will contain the lowest 8 bits (the character) cmp cl, 33 Compares the character against decimal 33 This is a preliminary check to quickly filter out non-whitespace characters setb dl Sets the dl register to 1 if the character is below 33 (space, tab, newline, etc.) Uses a conditional set instruction movabs rax, 4294977024 Loads a pre-computed 64-bit constant This constant represents a bit mask for whitespace detection shr rax, cl Shifts the bit mask right by the character's value This dynamically positions the mask based on the input character and al, dl Performs a bitwise AND between the shifted mask and the previous condition Produces the final boolean result in al ret Returns the result (0 or 1) in al This implementation is a highly optimized branchless method for checking whitespace characters, using bit manipulation instead of multiple comparisons. It avoids conditional jumps, which can be slower on modern CPUs. The code checks for space (' '), newline ('\n'), carriage return ('\r'), and tab ('\t') in a single, efficient operation.

I wrote an article about how Rust helps you beyond just memory safety. I based it on a talk by the brilliant Matt Godbolt, the creator of Compiler Explorer.

Matt Godbolt sold me on Rust (by showing me C++)
Matt Godbolt, of Compiler Explorer fame, is awesome and you should scour the web for every single bit of content he puts out. That is…

Perhaps a revolution but very likely a result of leading politicians, including Merz, saying it’s necessary. You could likely have seen this development any time since Feb 22 if Scholz & 🚦coalition had made the case for it & if CDU had not waited till the day after the election to make the argument.

According to this @zdfde.bsky.social Politbarometer poll, 76% of Germans are in favour of more defence spending with new debt.

This includes 90% of CDU voters, 52% of Die Linke voters and even 70% of FDP voters.

A fiscal public opinion revolution.
