ear training app with Web Audio API

I studied at a conservatory and we always used song mnemonics for intervals. Star Wars for a perfect fifth, Jaws for a minor second. Couldn't find a clean web app that does this, so I built one in a day. What it does: Interval and chord recognition with 12 intervals and 8 chord types Spaced repetition (asks more of what you get wrong) 4 sound types: piano, synth, guitar, sine wave Daily challeng...

Flutter Desktop Input Design — Where Does the Enter Key Actually Go?

From "pressing Enter does nothing" to "the Enter on the arrow-key area still inserts a newline", these desktop input field pitfalls ultimately trace back to a Focus model problem. Prologue: a bug reported by a user "After typing in the input field, the first Enter inserts a newline, and only the second one actually submits." This is an extremely representative problem in Flutter des...

How cxgrd differs from AI agent-based code review tools

In my previous post, I introduced the CLI tool CXGRD which I built to prevent agents from breaking architecture. CXGRD computes blast radius using dependency graph traversal — a deterministic analysis of real import, call, and reference relationships in your codebase. This post explains what that means and how it differs from AI agent-based code review tools. The core difference AI a...

I Almost Lost Years to This. So I Built an Open-Source Blocker Instead.

I've loved computers for as long as I can remember. Games, building things, staying up way too late just trying to figure out how something worked. That same curiosity is also how, very young, I ended up finding adult content online. What started as curiosity turned into something I repeated morning and night, for years, until it didn't feel like a choice anymore. It felt like something that had a...

CSS `corner-shape` generator with proper fallbacks

I wanted to use corner-shape: squircle in a real design, but the fallback turned out to be more complicated than I expected. Reuse the same number for border-radius and the corner comes out a visibly different size. So I built a generator where you can try corner-shape values and copy the CSS it produces: https://a-dev.github.io/probes/corner-shape submitted by /u/a-dev0 [link] ...

Docker - redes e volumes na prática

Mas uma aplicação real raramente é um único container: normalmente há uma API, um banco de dados, um cache, talvez uma fila de mensagens — cada um em seu próprio container, precisando se comunicar.

I Love Dogs, But Dogs Scare Me — So I Built Pawsitive with Gemini 🐾.

This is a submission for Weekend Challenge: Dog Days Edition What I Built I love dogs. There, I said it. And yet, I am also scared of them. It is a strange combination. I can happily watch dog videos for hours, admire every dog I see on the street, and still instinctively tense up when one suddenly runs towards me. A lot of that comes from a traumatic experience I had with a dog as...

Chíne tréile

When I was immersed in the Irish language for a week in Donegal last month, I made plenty of mistakes. But there’s one mistake that I’m actually quite pleased I made. The emphasis at Oideas Gael is on conversational Irish, so our teacher would often put us into groups of around four people to discuss a particular topic. On one occasion, the topic was food. We had some starter questions to ask on...

Taming Kafka Lag Spikes with KEDA Scale-to-Zero

How we turned always-on Kafka sinks into on-demand workers that shrug off nightly bombardments — by scaling on the right signal, tuning per-pod drain rate, and keeping autoscaling from sabotaging itself. Every number in this post is measured from a local lab you can run yourself — the full code is on GitHub, and the Appendix has the commands. The problem We run a fleet of Kafka sin...

A 36% margin became 6% at month-end, and nothing was posted wrong

Every number below comes from an actual document in that system. At billing, the month looked good Revenue 20,000 COGS at standard 12,800 Margin 7,200 = 36% ...

别再手写图表了！用AI轻松搞定数据可视化

图表不会画？跟AI说句话就行 写代码画图这件事，劝退过不少人。编辑器打开了，文件是空的，脑子里想的是"画个折线图"，手却不知道往哪放。查文档、调参数、处理日期格式、挪图例……折腾半小时，数据还没理清楚。我太懂了，因为我自己就是这么过来的。 现在情况不一样了。ChatGPT、Claude、Copilot，随便挑一个，你跟它说"我想看什么样的图表"，它就把代码给你写好了，而且一次跑通的概率不低。这不是什么科幻设定，我天天这么干活。 AI到底在干嘛？ 说白了，AI不负责画图，它负责把你想画的东西翻译成代码。你说人话，它出Python、R或者JavaScript，然后你的数据就变成图了。常用的搭配大概是这些： Python配Matplotlib或Seaborn，做静态图、论文插图，稳 Python配Plotly，要交互、能缩放能悬停的那种 R配g...

Why Trend-Data Scrapers Silently Fail (And How I Fixed It)

You start a Google Trends scrape. It runs for twenty minutes. It comes back with nothing. You already paid for it. That's not a one-off bug, it's the most common complaint on scrapers in this category, across the board. Not "wrong data," not "missing feature." Just: ran, cost money, returned nothing. I wanted to understand why that keeps happening, and whether it's actually fixable. It'...
