Why something executes before something else? [duplicate]

I've been struggling to understand why line marked 2 executes before the function in line marked 1 returns a value: // this gets called when we press the add button function addNewItemButton() { // get info and construct let date = getCurrentTime(); let isE = document.getElementById("medInputE").checked; let isB = document.getElementById("medInputB").checked; ...

What Changes After the First 1,000 Orders: The Engineering Side of Scaling eCommerce

Last updated: August 2026 The first few orders of an online store rarely make anyone think seriously about infrastructure. When there are only a handful of orders, almost any problem can be handled manually: check inventory, correct a status, contact a supplier, or figure out why incorrect information is appearing on a product page. At 10 orders, this is still a perfectly workable model. At 100,...

How to Repair Corrupted PDFs in the Browser with Vue 3 and pdf-lib

A corrupted PDF is one of the most frustrating file problems. You have important content inside, but the document won't open, opens with garbled text, or shows missing pages. The file might be damaged from a bad download, a converter error, or a storage glitch. Recovering content from a broken PDF doesn't require complex forensic tools. Often, the individual pages are still readable — it's the do...

I give up - and here's what building an app for elderly parents actually taught me

I spent a long time building How Are You?! An Android app that quietly watches over an elderly person living alone. No wearable, no button to press, no "are you okay?" popups. You install it once on their phone and forget it exists. It learns their normal day and if it detect anomaly in the behavior, like not moving in the park, to send notification to somebody. I was proud of it. Technically it'...

I benchmarked my language against Rust and Zig, and deleted my best number

I have been building machin for a while — a Go-flavored, type-inferred language that compiles through C to a single native binary. It has grown a lot recently, and I wanted to answer the obvious question honestly: does it beat Rust and Zig at anything? It does, at two things, decisively. But the first thing I found was not a win. It was my own benchmark quietly lying to me, and the number it was ...

I Kept Retrying a Local Model Into the Right Shape. Turns Out I Didn't Have To Retry At All.

The constraint on this one wasn't the AI part, it was the client: nothing leaves the device. No API calls, no cloud model, full stop, because the documents being classified weren't allowed off the machine they landed on. So the whole pipeline runs on a quantized model through llama.cpp, and its one job is boring on purpose - read a chunk of text, output exactly one of five category labels, nothing...

I Queried 50 Company Profiles — Here's What I Learned About AMD

webdev, #ai, #api, #discuss AMD just spent $390 million in stock to buy Taalas, a 35-person startup that etches AI models directly into silicon. The press release called it a "strategic move to accelerate inference performance." I didn't buy the phrase, so I wrote a script and pulled 50 company profiles to see what the data actually says. import os import requests API_KEY = os.envir...

Ed25519 vs ECDSA: Why the Nonce Decides Everything

ECDSA and Ed25519 both sign data with elliptic curves, and both produce a 64-byte signature that verifies in a fraction of a millisecond. The difference between them is almost invisible on paper: ECDSA needs a fresh secret random number for every signature, and Ed25519 computes that number instead. That one design choice is the reason real people have lost real private keys. A digital signature a...

Filtering, and Pagination in Next.js 15 The Pattern I Actually Use

Every dashboard eventually needs the same three things. A search box, a few filters, and pagination once the list gets long. The version I used to build kept all of that in useState, which meant losing your filters the moment you refreshed the page or shared a link with someone else. Keeping this state in the URL instead fixed both problems at once. Here is the setup. 1. Why URL Sear...

Cloudflare for Developers: What It's Great At, Where It Bites, and How to Actually Use It

Cloudflare is best understood not as "a CDN" but as a programmable network that sits between your users and your origin, plus a growing platform for running code and storing data at the edge. For most developers the wins are real and immediate — free TLS, a fast global CDN, DNS you don't have to babysit, and a serverless runtime with almost no cold start. The catches are just as real: the Workers ...
