Signal president Meredith Whittaker has warned that AI chatbots “are not your friends,” “are not conscious beings,” and “are not sentient interlocutors,” pushing back against the growing tendency of users to treat AI systems as trusted companions. The comments came in a Bloomberg interview published
Hackers breached Brazil’s national civil defense alert system overnight, sending fake “Extreme Alert” notifications containing the word “misantropi4” to millions of mobile phones across at least seven states. The Civil Defense Alert platform was taken offline at 1:30 am on Saturday after the Ministr
You picked JavaScript (or Python, or Go, or Java) partly so you'd never have to think about memory. No malloc, no free, no dangling pointers. The runtime cleans up after you. So why does your app get slower the longer it runs? Why does the process climb from 80 MB to 1.5 GB overnight, then feel inst
A great CLAUDE.md is not the longest one. It is the one where every line changes what Claude does. The whole skill is knowing what belongs in it — and, just as importantly, what does not. Start with a one or two line project description and your stack, with version numbers. Claude infers a lot from
Softadastra is Becoming The C++ Tooling Company Softadastra is changing direction. For a long time, the company explored different ideas around software, infrastructure, platforms, and developer products. Each idea had value, but over time one problem became more important than the rest. Developer t
Error Handling — Learning to Love if err != nil In part 3 I covered goroutines and channels, and how Go's concurrency model sidesteps a lot of the ceremony I was used to from the JVM. This time I'm tackling the thing I complained about in part 1 of this series before I'd even really tried it: error
Karpathy gave us vibe coding: "see stuff, say stuff, run stuff, copy and paste stuff, and it mostly works." Since then, the industry has kept trying to turn it into a tidy autonomy ladder — Level 0, Level 1, all the way up to fully autonomous development. That ladder is useful. It is also incomplete
You've read the guides. You've watched the YouTube videos. You've bookmarked 47 "top interview questions" articles. And yet, when someone asks you "tell me about yourself" out loud — you freeze. This isn't a knowledge problem. It's a practice problem. Reading about interviews is passive. Your brain
I've been building PR Focus, a Chrome extension that helps developers triage GitHub pull requests. One of the first decisions I had to make was: how do I actually sort PRs by priority? The obvious answer is "use AI to score the risk". But I didn't want to rely 100% on an LLM because: AI is inconsist
Disclosure: I work on Opennomos (linked at the end). This is a thinking-out-loud post about a problem we've spent the last year trying to model. Ship a Web3 product launch and you've watched this play out: Week 1: 10,000 wallets connect, TVL spikes, Twitter +5K followers. The CFO smiles. The VC retw
I used Viator in ChatGPT and Claude to find the best destinations to visit in Kyoto, Japan — one of those chatbots offered much better picks.
Revisit "Rocky," the origin story of film's most famous fictional boxer Rocky Balboa, with a rewatch on Netflix to celebrate the movie's 50th anniversary
The Ninja AutoBarista Pro is an ambitious automatic coffee machine with espresso, drip, and cold brew functions, but I’m not sure it meets all its marks.
Sleep doctors explain how taking an invisible day can help lower cortisol and reduce 3 a.m. wake ups for better rest.
You don't have to leave your couch to travel the universe with these sci-fi picks.
This is the Motorola Edge 70 Pro. It launched back in April, and it costs €540 with 8GB of RAM, and 256GB of storage. Depending on the location, there are a few Pantone colors to choose from: Titan, Zinfandel, Lily White, and Tea. In the box, you'll find the phone, a USB-C cable, and a hard case wit
So far we have seen the planner build candidate paths and rank them by cost, choose join methods and join orders, and estimate those costs from statistics. But before any of that cost comparison begins, the planner does something else first. It takes the incoming Query tree and rewrites it once into
The Quest Begins (The "Why") I was building a simple rate limiter for a side‑project API. The idea was dumb‑simple: every time a request came in, I’d insert a row into a request_log table with the user ID and a timestamp, then count how many rows existed in the last minute to decide whether to allow
Everything from 1.4.1 through 1.4.9 happened inside a single function, standard_planner(). Building paths, costing them, searching for a join order, estimating cardinality from statistics: all of it runs inside that one function. Yet PostgreSQL does not call standard_planner() directly. It puts anot
By the time 1.4 ends, the planner has produced one PlannedStmt. Inside it is an execution tree built from Plan nodes, frozen into a form you can follow step by step, something like "go into the primary key index on users, fetch the one matching row, then output that whole row." But that is still onl
