PostgreSQL Query Rewriting Techniques The previous articles in this series covered performance problems you fix by adding indexes, restructuring joins, or tuning memory. This one is about the queries where the plan is "fine" — every node is doing something reasonable — but the query itself is asking the wrong question, producing unnecessarily large intermediate results or forcing the planner dow
I watched 30 users talk to the same voice agent Same script. Same questions. The only thing I changed was the response latency: 300ms, 500ms, 800ms. At 300ms, people just talked. No awkward pauses, no confusion. One user didn't even realize it was an AI until I told her afterward. At 500ms, something shifted. Users started talking over the agent. They'd ask a question, wait half a second, then r
Hey Dev Community, Like many of you, I hit a wall with GA4. It’s powerful, sure—but it’s also cluttered, slow, and often feels like it was designed for a data scientist rather than a developer or a brand owner who just needs to see what’s working.

The "Unsharable" Dashboard Problem Imagine this common B2B SaaS scenario: An executive opens your analytics dashboard. They spend three minutes configuring the data—they filter the status to "Active," set the date range to "Last 30 Days," sort the table by "Highest Revenue," and navigate to Page 4.

Building a Search Bar for Your Firefox New Tab Extension A search bar is the highest-ROI feature for any new tab extension. Users type queries dozens of times per day — if your extension can save them from navigating to google.com first, that's real value. Here's how I built the search bar in the Weather & Clock Dashboard extension. <form id="search-form" class="search-form" role="search"> <di
Keyboard Shortcuts in Firefox Extensions: A Complete Guide Keyboard shortcuts make extensions feel native. A new tab extension that users can control without clicking feels much more polished. Here's how to add them to your Firefox extension. { "manifest_version": 2, "commands": { "toggle-dark-mode": { "suggested_key": { "default": "Ctrl+Shift+D", "mac": "Command+Sh
The New Tab Page Is Prime Real Estate. Are You Wasting It? You open a new browser tab dozens of times a day. Most people see either a blank white page, or a corporate-designed "inspiration" page they never asked for. That's a waste. Let's be conservative: 20 new tabs per day × 300 working days per year = 6,000 glimpses at your new tab page per year. Each glimpse lasts maybe 2-3 seconds before yo
SQL is widely known for data querying and manipulation but systems do grow; data becomes larger; processes become repetitive and operations become sensitive. SQL has some features which enables it to be considered a fully fledged programming language. Some of the features which I discuss in this article are procedures, functions and transactions. Each of these concepts serve distinct purposes. Sto
