My iPad 2021 10.2" was flawless but some weeks ago it was updated to iOS26 by mistake and it became so slow on basic stuff (like showing the keyboard). Made me terrified of doing any upgrades

Also the fact that its written in Ruby on Rails probably doesn’t make it easier, performance wise.

Honestly. They’re already performing miracles with RoR.

How many non Ruby apps and all the databases and systems behind could climb their traffic 14x when they probably only perf-tested for a sustained 2-3x and, and paid for a profitable amount of rack space rather than a “lol, VC money, we’ll 10x later” amount of infra.

Systems engineers generally don't run performance tests at 2x or any specific scale.

You load test and see how much it takes until the system falls over - basically you DDoS yourself and see what the numbers were when things broke, and what broke first second so on. Maybe in a sandbox maybe against prod.

It's very telling that issues began almost to the day of the Microsoft acquisition.

Tell that to Shopify that handles 8.15 million requests per second and processes $5.1M USD per minute in sales during Black Friday. You scale your architecture, not your programming language.

Suddenly after 18 years, Ruby on Rails is the issue?

Similarly, I've created a simple Pi extension [1] that allows you to summon your LLMs inline from your notes (obsidian or any text format) and it's able to apply any edits (via Pi edit tools)

For me, whenever I took creatine I got headaches. (I drank enough water, and I could reproduce the issue everytime I tried it, so stopped it as it felt wrong)

I feel extremely lethargic whenever I take even 5g of it. I also drink 2 - 3 liters plain water a day, so I don't think it's dehydration.

I remember some years ago after coming from work at 6 pm I was dead tired at home thinking it was due to hard work during the day. Then one summer day decided to code side projects on my balcony and I was building until midnight full of energy.

I created a small PI extension that always watches relevant directories and answers me in place, without switching context, or using a chat interface. Still experimenting but I like it.

I used them because they had the fastest chat response. (Dont think that’s the case anymore, and they introduced some UI blocking feature on load which is irritating, but still use it mainly due to habit)

That chat history dark pattern is the main reason I never use Gemini. Its a shame.

Which dark pattern is that?

Is it me or the mentions of Kagi on HN are overly positive?

Not sure about the compiler but prominent users of llm agents (Mitchel Hashimoto, Armin Ronacher etc) has mentioned that Go gives better results for agentic coding.
