Interactive Programming in C (2014)

news.ycombinator.com Unknown 2025-12-29 16:16:35

December 23, 2014 nullprogram.com/blog/2014/12/23/ I’m a huge fan of interactive programming (see: JavaScript, Java, Lisp, Clojure). That is, modifying and extending a program while it’s running. For certain kinds of non-batch applications, it takes much of the tedium out of testing and tweaking during development. Until last week I didn’t know how to apply interactive programming to C. How does one go about redefining functions in a running C program? Last week in Handmade Hero (days 21-25),

No Cheese Please

news.ycombinator.com Anthony Grafton 2025-12-29 09:42:11

Libraries​ were all the rage in Renaissance Europe, and no wonder. Theatres of knowledge, grandly decorated and proudly displayed, they hosted dramas of many kinds. Learned men used them for lively conversation on such irresistible topics as the philosophies of Hermes, Zoroaster and Pythagoras or relations between the later Roman Empire and the Persian king Shapur II, which Angelo Poliziano, Pico della Mirandola and others debated in the new Florentine library of San Marco. Yet they were also –

Easy dynamic dispatch using GLIBC Hardware Capabilities

news.ycombinator.com Christian Kastner 2026-01-10 04:45:20

TL;DR With GLIBC 2.33+, you can build a shared library multiple times targeting various optimization levels, and the dynamic linker/loader will pick the highest version supported by the current CPU. For example, with the layout below, on a Ryzen 9 5900X, x86-64-v3/libfoo0.so would be loaded: In the meantime, ggml has extended its support for its own dynamic dispatch to arm64 and ppc64el , the lack of which originally motivated this work.

Mystery Man Shines a Spotlight on the Shadiness of Trump’s Crypto Venture

Last month, the Aqua 1 Foundation, founded by Dave Lee, purchased $100 million worth of tokens from the Trump family’s cryptocurrency venture World Liberty Financial (WLF. Someone putting cash directly into the President’s coffers is a normal thing in the Trump era, but there’s something odd about this particular purchase.

Automatically Packaging a Haskell Library as a Swift Binary XCFramework

Announcing xcframework or: the happy path for wiring a Haskell dependency to your Swift app I’ve written about Haskell x Swift interoperability before.

Phrase origin: Why do we "call" functions?

news.ycombinator.com Arthur O Dwyer 2026-01-26 11:04:45

On StackExchange, someone asks why programmers talk about “calling” a function. Several possible allusions spring to mind: Calling a function is like calling on a friend — we go, we stay a while, we come back. Calling a function is like calling for a servant — a summoning to perform a task. Calling a function is like making a phone call — we ask a question and get an answer from outside ourselves. The true answer seems to be the middle one — “calling” as in “calling up, summoning” — but indi

Algorithms like Brotli compression and Zstandard compression achieve even greater efficiency by allowing the use of dictionaries of commonly encountered strings, so you don't need any copies of them in the compressed resource. These algorithms ship with a predefined default dictionary that is used when compressing HTTP responses.

Publishing Pepys

Two hundred years ago this month, Samuel Pepys’s diary was published to great acclaim. Readers of the first edition in 1825 relished Pepys’s ‘honest’ observations and ‘private anecdotes’. While writing his journal in the 1660s, Pepys had worked hard to keep it secret. He knew he was placing his livelihood at risk by recording seditious criticisms of his superiors, along with details of his own bribe-taking and sexually explicit accounts of his ‘amours’.
