LLMs tell bad jokes because they avoid surprises

LLMs generate slop because they avoid surprises by design LLMs suck at comedy, art, journalism, research, and science for the same fundamental reason Dan Fabulich 5 min read · 3 days ago 3 days ago -- Listen Share Have you ever asked an LLM to tell you a joke? They’re rarely funny at all; they never make you actually laugh. There’s a deep reason for this, and I think it has serious implications for the limitations of LLMs, not just in comedy, but in art, journalism, research, and science. Jo

Does OLAP Need an ORM

TL;DR · ORMs have proven to be useful for many developers in the OLTP/transactional stack (Postgres, MySQL, etc). · OLAP/analytical databases like ClickHouse could potentially benefit from ORM abstractions. · Existing transactional ORMs probably shouldn’t be extended to OLAP due to fundamental differences in semantic meaning between OLTP and OLAP. · Moose OLAP (part of MooseStack) is an open source, MIT-licensed implementation of an ORM-like interface for ClickHouse, inspired by tran

Lessons learned from building a sync-engine and reactivity system with SQLite

Over the last couple of months, I've been trying to build the dream: A local-first, end-to-end encrypted and reactive app, with all of the user's data in a local SQL database but continually synced to a remote server. This article summarizes my learning and how I ended up building a minimal sync engine for SQLite with full reactivity. First Try: PGlite and Electric My first try was with Electric and a WASM-based version of PostgreSQL called PGlite that can run directly in the browser. I ev

Good system design

I see a lot of bad system design advice. One classic is the LinkedIn-optimized “bet you never heard of queues” style of post, presumably aimed at people who are new to the industry. Another is the Twitter-optimized “you’re a terrible engineer if you ever store booleans in a database” clever trick. Even good system design advice can be kind of bad. I love Designing Data-Intensive Applications, but I don’t think it’s particularly useful for most system design problems engineers will run into. Wha

ChatGPT's Boss Says You Still Shouldn't Trust It as Your Main Source of Information

When you start a conversation with ChatGPT, you might notice some text at the bottom of the screen: "ChatGPT can make mistakes. Check important info." That's still the case with the new GPT-5 model, a senior OpenAI executive reiterated this week. "The thing, though, with reliability is that there's a strong discontinuity between very reliable and 100 percent reliable, in terms of the way that you conceive of the product," Nick Turley, head of ChatGPT at OpenAI, said on The Verge's Decoder podca

Brands might be cooling on satellite features, and that’s bad news for cheaper Androids

Mishaal Rahman / Android Authority TL;DR Chinese brands are scaling back satellite communication and keeping it for top-end models only. A reliable tipster says past high-end sat-com flagships sold poorly and were dropped. This could make global brands less likely to bring the feature to affordable phones. Satellite communication has been one of the most talked-about phone features in the past couple of years, and it’s no longer just for emergencies. Just this week, our APK teardown showed h
