31% das respostas mostraram sérios problemas de fornecimento - atribuições ausentes, enganosas ou incorretas.

20% continham grandes problemas de precisão, incluindo detalhes alucinados e informações desatualizadas.”

Não fique verde de vontade, assina a gente por 5 reais e receba um monte de tiras exclusivas no mail: catarse.me/linhadotrem
Tira em 4 quadros (e meio): 1) Voz de fora do painel: "com a palavra, ministro luiz fúcsia", um homem desenhado com o semblante similar ao Luiz Fux, porém com a pele fúcsia, ajeitando os óculos no rosto, responde, com um balão rosa "obrigado". Um balão azul, de fora do painel "com licença". 2) Balão rosa, de fora do painel: "pois não, ministro cristiano denin", e um homem, desenhado com o semblante similar ao Cristiano Zanin, porém com a pele azul, gesticulando com a mão, responde, com um balão azul "acho que erramos a ordem" 3) Balão azul, de fora do painel: "agora seria a ministra carmim lúcia" e uma mulher, desenhada com o semblante similar à Carmem Lúcia, porém com a pele vermelha, segurando folhas de papel, responde, com um balão vermelho: "muito obrigada" 4) Balão vermelho, de fora do painel: "queria mencionar a presença da ex-ministra rosa webe" e uma mulher, desenhada com o semblante similar à Rosa Weber, porém com a pele rosa, acena com uma das mãos, Dentro desse quadro, um quadro menor, com o cartunista desenhando sobre uma mesa de desenhos, em preto e branco, e um balão laranja de fora do painel de alguém dizendo "CHEGA".

Remember when COVID vaccines were first available? Remember how they saved lives and helped us move toward normalcy? Remember how relieved and grateful we were? Remember how amazing our healthcare workers were? Remember how science rescued us?

A guide to programming paradigms:
Imperative: functions can have side effects
Functional: functions must be pure
Reversible: functions must be pure and bijective
Analytic: functions must be pure, bijective and infinitely differentiable
Agile: functions must take part in daily standups

The #JWST has opened a new window on the universe with the MIDIS (MIRI Deep Imaging Survey) project, focusing its instruments on a tiny patch of sky in Fornax, called the Hubble Ultra Deep Field (HUDF).

This area, already made famous by...

"An area of deep space with thousands of galaxies in various shapes and sizes on a black background. Most are circles or ovals, with a few spirals. More distant galaxies are smaller, down to being mere dots, while closer galaxies are larger and some appear to be glowing. Red and orange galaxies contain more dust or more stellar activity."

C++ is evolving! Still lacking a borrow checker, but the syntax and the ergonomics are improving!

One concept that creates misunderstanding is “scientific consensus.”

It’s time to stop using this shorthand and make clear what it really means.

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.
