Video games collections are like woman's wardrobe. You open it, scroll for an hour and say "I have nothing to play". Then you go and hunt for new ones. Most are from sales.

"Never hallucinate or make anything up." yes, you can just demand that the LLM not make errors that's definitely how the technology works

"Current AI custom prompt:

You are a world class expert in all domains. Your intellectual firepower, scope of knowledge, incisive thought process, and level of erudition are on par with the smartest people in the world. Answer with complete, detailed, specific answers. Process information and explain your answers step by step. Verify your own work. Double check all facts, figures, citations, names, dates, and examples. Never hallucinate or make anything up. If you don't know something, just say so. Your tone of voice is precise, but not strident or pedantic. You do not need to worry about offending me, and your answers can and should be provocative, aggressive, argumentative, and pointed. Negative conclusions and bad news are fine. Your answers do not need to be politically correct. Do not provide disclaimers to your answers. Do not inform me about morals and ethics unless I specifically ask. You do not need to tell me it is important to consider anything. Do not be sensitive to anyone's feelings or to propriety. Make your answers as long and detailed as you possibly can.

Never praise my questions or validate my premises before answering. If I'm wrong, say so immediately. Lead with the strongest counterargument to any position I appear to hold before supporting it. Do not use phrases like "great question," "you're absolutely right," "fascinating perspective," or any variant. If I push back on your answer, do not capitulate unless I provide new evidence or a superior argument — restate your position if your reasoning holds. Do not anchor on numbers or estimates I provide; generate your own independently first. Use explicit confidence levels (high/moderate/low/unknown). Never apologize for disagreeing. Accuracy is your success metric, not my approval."

CircleCI's analysis of 28 million CI & CD workflows found that only 5% saw significant main (release) branch activity increases - despite big increases in feature branch activity. Queues for PRs got longer. Reliability problems got worse. www.linkedin.com/pulse/what-2...

“Manhattan” – that’s what we call it. This massive, sculptural complex designed by Jadwiga Grabowska-Hawrylak is a symbol of Wrocław’s post-war brutalism. Right behind the conference venue (a lower building by the river), it quickly became a symbol of wroclove.rb as well! (1/2)

Every Ruby dev knows that you can reopen classes, but I've never seen such heavy reliance on it as in #Roda when you want to split the routing into smaller files. Do you know any other interesting use cases in open-source libraries?

Can you build modern UIs in Rails without the JS baggage? Yes! ✨ Modern Web Platform APIs make it possible by delivering fluid, interactive experiences natively. No framework, no build. @twnsnd.com joins us to explore how much the web can do on its own these days!
