pointer-events

The pointer-events property controls whether an element can become the target of pointer events like clicks, hover states, and other pointer-based events. In other words, it lets you decide whether the browser should treat an element as interactive when the … pointer-events originally handwritten and published with love on CSS-Tricks .

I spent a week trying to intercept Slack push notifications from a Chrome extension. Here's why it's impossible.

After I published my last article about building a Chrome extension that speaks browser notifications aloud, a commenter asked a question I didn't have a good answer to. He pointed out that a lot of web apps — Slack, Gmail, most modern tools — fire their notifications from a service worker via registration.showNotification() , not from the page's JavaScript context. My MAIN world override of window.Notification would never reach those. He was right. And I told him I'd look into it. I spent a week researching whether there was any way to close that gap. There isn't. But the reason why is more interesting than a simple "no." Two ways a website can show you a notification When a website sends you a browser notification, it can do it in one of two ways. The first is the constructor path. The page's own JavaScript calls new Notification("You have a message") directly. This is common for in-tab alerts, real-time updates when you're actively on the site, or any notification triggered by something you just did. The second is the push path. The browser receives a push event from the website's server, wakes up the website's service worker in the background, and the service worker calls self.registration.showNotification() from inside its own scope. This is what happens when Slack notifies you of a new message while the tab is closed or backgrounded. The page never runs. No page JavaScript ever fires. My extension catches the first path. The MAIN world content script overrides window.Notification before any page code runs. But the service worker never touches the page's window. It has no window . It runs in a completely isolated thread, completely separate from the page, and calls showNotification on itself. The override is never reached. Why can't the extension reach the service worker? This is the part that took me a week to fully accept. Chrome extensions can inject content scripts into web pages. They can run code in the MAIN world or the ISOLATED world of a page. They can

Five Local-First Mac Apps I Built to Fix Everyday Workflow Problems

Over the last few months, I’ve been turning small workflow problems I encounter on my Mac into focused utilities. Rather than building one enormous productivity suite, I wanted each app to solve a specific frustration well. I also wanted to build software the way I prefer to use it: local-first, available through a one-time purchase, and usable without creating another account or paying for another subscription. Here are five of the apps I’ve built so far. ScreenShelf My desktop used to become a temporary storage zone for screenshots, folders, documents, links, and files I needed for active projects. Folders helped with long-term storage, but they were not always useful for things I wanted to keep visible and nearby. ScreenShelf creates a customizable visual shelf for: Files and folders Screenshots and images Links Text Applications Frequently used project materials You can organize items across separate pages, customize the appearance of each page, and keep different groups of materials available for different projects. It also includes a Recents area that surfaces recent screenshots, which is helpful when the small screenshot preview disappears before you can interact with it. ScreenShelf is essentially the space between a cluttered desktop and a deeply nested folder system. Learn more about ScreenShelf PopNote Some reminders are too small for a full task-management system. You might need to remember to send a file in twenty minutes, check something after lunch, or complete one small step before ending the day. PopNote is a lightweight menu bar app that creates timed pop-up reminders on your Mac. The reminders appear as small visual bubbles rather than traditional notification banners. You can choose a time, add an icon, and let the note reappear when you need it. It is designed for temporary reminders that should remain noticeable without becoming another project to organize.

find command finds things

Recently I learned: find is a useful command to find files in your directories. find folder1 folder2 folder3 This dumps every file and directory under those folders. It also supports flags such as -name "*.txt" to find files matching a particular pattern. There are also filters for size, permissions, and last modified date. I'm thinking this would be a great tool for sanity-testing code that creates nested directories (like a new Docker container's filesystem). This command will give me a full flat listing of the resulting tree (like a deeply nested ls command`). The downside is of course it can dump a lot of output, but in sanity-testing scenarios, there shouldn't be that many files anyways. Something interesting is that this command will take multiple folders before the flags. I'm used to thinking of programs where the arguments are all positionally ordered, so if you don't pass a flag it just assumes the next thing is a regular argument. In this case, find checks whether an argument looks like a flag (starts with - ) before deciding whether to treat it as a path or as part of the expression. I wonder if this is a common pattern across other Linux commands. (Claude says find is special case, but I need to look more into this.)

Built an autonomous dependency upgrader using Loop Engineering and LangGraph

You have a project with 20 dependencies. Half of them are outdated. Running ncu -u or pip install --upgrade upgrades all of them at once — and when something breaks, you have no idea which package caused it. So you don't upgrade. The deps rot. Security patches pile up. loopgrade fixes this. It upgrades one dependency at a time, runs your test suite after each upgrade, commits if it passes, reverts if it fails, and moves on to the next one. When it's done, it gives you a full report of what was upgraded, what failed, and why.

Our ‘explosive diarrhea parasite’ future

Bryan, a food broker from Michigan, wasn't sure if he'd be able to make it to urgent care in time. He started feeling off on Thursday, and by Saturday, he was having to use the bathroom every 15 to 30 minutes. "It's no joke about the explosive diarrhea," Bryan, who asked that his last name […]
