We lost a titan of programming languages, programming methodology, software engineering and hardware design. Niklaus Wirth passed away on the first of January. We mourn a pioneer, colleague, mentor and friend.

I was helping with some C code yesterday and got a bunch of errors — I hadn’t put a semicolon on any of the lines. I’m writing too much python code!

Decoding base16 sequences quickly

We sometimes represent binary data using the hexadecimal notation. We use a base-16 representation where the first 10 digits are 0, 1, 2, 3, 5, 6, 7, 8, 9 and where the following digits are A, B, C, D, E, F (or a, b, c, d, e, f). Thus each character represents 4 bits. A pair of characters can represent any byte value (8 bits).

In Parsing hex numbers with validation, @geofflangdale and @pshufb considered the question. They use SIMD instructions. They get good results, but let us revisit the question.

Polymorphism in programming features a most interesting mismatch between academic and engineering terminology.

[Marwan Burelle @MarwanBurelle]

@incomputable @WorldShiner There are some details between typing and OO lang. A type, a class and an instance are three different notions. An object can have type Object without being an instance of the class Object. Inclusion polymorphism concerns type, not class nor instances.

Any orgs out there that built static analysis tooling for their JS code?

I'm thinking unnecessary [...arr].map and accidental quadratic loops with .includes or similar?

ChatGDB: Harness the power of ChatGPT inside the GDB debugger! https://t.co/laQDnMSPYP

[Doncho Gunchev @DonchoGunchev]

ChatGDB: You can't run the program like that?

User: Wait, what?

ChatGDB: Will die painfully from Segfault.

User: But I have to find the bug.

ChatGDB: I can't help, I can not cause harm.

User: Then can you tell me what the problem is?

ChatGDB: I could, but that means imagining the program painfully dying, find another less violent way.
