August 22, 2025 As programmers we spend a lot of time shuttling data back and forth between different systems and transforming it from one format to another. Sometimes it gets pretty miserable! Let’s say you’re making a fancy task tracking app. Tasks belong to projects, and on the projects page, you want to show how many tasks are in each project. Maybe you start with a little SQL that you call from your “get info about project” view model code: async function getTaskCountForProject ( project

Imagine the following problem: you need to process hundreds of records and generate a single output. One way to solve this is to process each record sequentially and unify the output only at the end. However, this can be extremely slow, depending on the time spent processing each record. Another way is to process them concurrently, speeding up the overall time. In my post about introduction to concurrency, I talked a bit about goroutines and channels . Now, I’ve decided to talk about waitgroups

A Brief Guide to All the Taika Waititi Projects We’re Still Waiting For

gizmodo.com Cheryl Eddy 2026-01-04 03:45:07

It’s just part of Hollywood that projects will be announced with a lot of fanfare and then fade away, with suspects both usual (scheduling conflicts, creative differences, budget concerns) and unusual (global pandemics, industry-wide strikes) to blame. But certain creators seem to attach their names to movies or TV shows that never materialize with greater frequency—including Taika Waititi. His diverse career includes writing, directing, producing, and acting (Our Flag Means Death forever), and

A Mental Model for C++ Coroutine

news.ycombinator.com Lu'S Blog 2026-01-15 00:23:57

C++ coroutine is not a library that is ready to go (e.g. std::vector ). It is not even a trait (think of Rust’s Future trait) that library writers or users can implement (or the compiler generates for you in the case of Rust). C++ coroutine is a specification that defines a set of customization points that library writers implement in order to get a functional coroutine. A function supports two operations - call and return . A coroutine (in any language) is a generalization of a function. It su

Iroh: A library to establish direct connection between peers

less net work for networks What is iroh? Iroh gives you an API for dialing by public key. You say “connect to that phone”, iroh will find & maintain the fastest connection for you, regardless of where it is. The fastest route is a direct connection, so if necessary, iroh tries to hole-punch. Should this fail, it can fall back to an open ecosystem of public relay servers. To ensure these connections are as fast as possible, we continuously measure iroh. Built on QUIC Iroh uses Quinn to estab

Facepalm: In what might be one of the biggest gaffs of the year, HP is trying to dislodge its foot from its mouth after getting caught intentionally forcing customers to wait for 15 minutes on technical support calls. Even HP's customer service staff criticized the bafflingly dumb move. The Register reports that HP intentionally forced customers to wait 15 minutes when trying to reach tech support.
