What’s the Fastest React Data Grid? Let’s Find Out (Benchmarks)

Web development has changed a lot. We have LLMs, AI-assisted coding, etc. But some things remain the same: architecture and performance. And one of the classic problems in many applications is presenting large amounts of data, which eventually leads to choosing the right data grid.I've always been surprised by how quickly this happens. You start working on a seemingly simple application, and a few months later you realize that, sorry, a regular HTML table just doesn't cut it anymore. Y

How to serve dynamic user announcements with static SSR performance

Have you ever loaded a SaaS app and seen an announcement banner flicker in 500ms after the page loads, shifting the entire layout down by 60px? That Layout Shift (CLS) destroys user experience and SEO rankings.Here is the architectural pattern for delivering dynamic, personalized in-app announcements without layout shifts or SSR hydration mismatch. The Anatomy of Hydration Layout ShiftsWhen an SSR page renders null on the server and then hydrates an announcement banner in a useEffect on the

How to Choose Period Door Furniture Without Compromising on Security or Authenticity

Restoring a period property is all about the details.You can preserve original fireplaces, restore timber floors, repair sash windows, and carefully match paint colours—but the wrong door furniture can still make an otherwise authentic interior feel noticeably out of place.Choosing the right period door furniture is more complicated than simply finding something that looks Victorian or Georgian. The hardware needs to complement the architectural era while providing the strength, reliability, and

React vs Angular for Enterprise Apps: How to Choose

When evaluating react vs angular for enterprise apps, the short answer is this: React is usually the better fit when you want flexibility, rapid UI innovation, and a broad ecosystem, while Angular is often the better fit when you want a highly structured framework with built-in conventions for large teams. Neither is universally superior; the right choice depends on governance, internal skills, product complexity, and how you plan to maintain the application over several years. Key takeaway

How to Choose the Right Test Management Software for Your Organization

Choosing test management software is an important decision for any QA or software development team. The right platform can make test planning easier, improve visibility into execution, reduce repetitive work, and help teams release software with greater confidence.However, selecting a tool simply because it has a long feature list can lead to poor results. A platform may have advanced reporting but lack the integrations your developers need. Another tool may be affordable but become difficult to

The API worked. The payload didn’t.

I kept shipping APIs I hadn’t really looked at.I’d ask whatever assistant was open Cursor, Claude, Antigravity, Trae for a users endpoint. It generated the route, the DTO, the response. The page rendered. I moved on.Then I opened DevTools → Network.Full objects on a list viewNulls everywhereVerbose keysExtra timestampsFields the UI never usedGzip made the response look small, so I ignored it.That was the mistake.

What the Average Big Five Result Actually Looks Like (n = 19,718)

Personality tests love to hand you a tidy "type". So we took 19,718 real Big Five responses — the IPIP-50 instrument, from the Open-Source Psychometrics Project — scored them into the five OCEAN traits, and looked at what the distribution actually says. Nobody is average on everythingThe first result is the bluntest one: 0 of 19,718 people scored in the top band on all five traits at once. Not a single person. "Average across the board" is a statistical fiction — real people are high on som

I built a detector for stuck Safe transactions. 93% of what it found was already dead.

The idea was clean enough to be suspicious. A Safe multisig splits one act into two things that are not the same: signing is off-chain and free, and executing is an on-chain call that costs gas, can be made by anyone, and is assigned to nobody.So transactions that already hold every signature they need just sit there. The money was approved and never moved.Finding them looks trivial. The Safe Transaction Service exposes each Safe's queue, and every queued transaction carries isExecuted, confirma

I Built a Free JSON Schema to Go Types Converter (Because schema2go Costs $19)

I Built a Free JSON Schema to Go Types Converter (Because schema2go Costs $19)Last year I was helping a colleague set up a new Go microservice. They needed to generate structs from a JSON Schema they'd inherited from the frontend team. I suggested schema2go — a popular CLI tool that converts JSON Schema to Go types.They installed it. Ran the command. Got basic structs. But when they tried to use it with their actual schema — which had nested objects, $ref references, and custom formatting

This is how I added an in-browser auto captions feature to my YouTube Shorts converter web application using Whisper AI and ffmpeg.wasm

A few weeks ago I launched Convert to Shorts — a free browser-based tool that converts horizontal videos to YouTube Shorts format (9:16) without uploading anything to a server. I wrote about the ffmpeg.wasm + Vite setup in a previous article.The most requested feature after launch was auto captions. Captions significantly boost Shorts engagement since most people watch without sound, and manually typing captions is tedious.The challenge: how do you add free auto captions to a privacy-first tool
