Ask HN: The government of my country blocked VPN access. What should I use?

news.ycombinator.com — Indonesia is currently in chaos. Earlier today, the government blocked access to Twitter & Discord knowing news spread mainly through those channels. Usually we can use Cloudflare's WARP to avoid it, but just today they blocked the access as well. What alternative should we use? GOVERNMENT, 2

Lucky 13: a look at Debian trixie

Please subscribe today to help us keep doing that, and so we don’t have to get good at marketing. LUCKY, 5

Some thoughts on LLMs and software development

martinfowler.com — I’m about to head away from looking after this site for a few weeks (part vacation, part work stuff). As I contemplate some weeks away from the daily routine, I feel an urge to share some scattered thoughts about the state of LLMs and AI. SOME, 8

The Synology End Game

lowendbox.com — I’ve been a Synology fan for many years. I used to roll my own NAS servers for home, but eventually decided that quieter, more energy-friendly dedicated NAS solutions were a better path forward. I don’t use a lot of their on-board apps, just basic file storage. SYNOLOGY, 12

My startup banking story (2023)

mitchellh.com — As a relatively new member of adult society, and an absolute infant of the business world, I didn't think much about bank choice. I figured: you put money in, you take money out, they're all the same. I also figured a local branch of a global bank is just a fungible tentacle of the giant banking machine, so also... who cares. Both incorrect assumptions, but let's relive and rediscover the effect of these assumptions as I did. STARTUP, 13

Nullable vs. Nullable in C#

einarwh.no — One of the most unfortunate parts of the nullability narrative in C# is the reuse of the T? syntax to denote two completely separate concepts for value types and reference types. This leads to some odd and confusing behaviour. NULLABLE, 18

Building your own CLI coding agent with Pydantic-AI

martinfowler.com — CLI coding agents are a fundamentally different tool to chatbots or autocomplete tools - they're agents that can read code, run tests, and update a codebase. While commercial tools are impressive, they don't understand the particular context of our environment and the eccentricities of our specific project. Instead we can build our own coding agent by assembling open source tools, using our specific development standards for: testing, documentation production, code reasoning, and file system operations.

In Search of AI Psychosis

astralcodexten.com — AI psychosis (NYT, PsychologyToday) is an apparent phenomenon where people go crazy after talking to chatbots too much. There are some high-profile anecdotes, but still many unanswered questions. For example, how common is it really? Are the chatbots really driving people crazy, or just catching the attention of people who were crazy already? Isn’t psychosis supposed to be a biological disease? Wouldn’t that make chatbot-induced psychosis the same kind of category error as chatbot-induced diabetes? SEARCH, 23

You no longer need JavaScript: an overview of what makes modern CSS so awesome

Sometimes CPU cores are odd

techaro.lol — One of the biggest lessons that I've learned in my career is that all software has bugs, and the more complicated your software gets the more complicated your bugs get. A lot of the time those bugs will be fairly obvious and easy to spot, validate, and replicate. Sometimes, the process of fixing it will uncover your core assumptions about how things work in ways that will leave you feeling like you just got trolled. SOMETIMES, 26
