My .md files are specific to my domain - game development using Unity. Something that is probably universal and is a good baseline for every project and domain:

- which libraries to use for standard problems - project structure, it helps if it has a name(vertical slice etc) - which things llm is free to edit, which not - naming, comments etc

And most importantly: "what not to do", and you should do this a lot: Whenever llm does something that is a code smell, make it fix it and make it add a new rule to agents.md.

I got the codex to write near perfect code with somewhat strict agents.md and coding standards(a separate .md file referenced from agents.md). My .md files have examples and a long list of do's and don'ts I accumulated over the last 6 months or so, totaling 300-400 lines. I plan every feature with it until I am satisfied with the general approach it wants to take, and then it oneshots it in 95% of cases. The planning takes anywhere from 5 to 30 minutes. The actual execution has gotten stupidly fast, most of the times it is faster than making a cup of coffee.

Good job on getting into running! I would highly suggest you find some "exercises for runners" videos on youtube and find some exercises that are comfortable for you to do. Focus on the exercises that are asymmetric(lunges etc). You can do most of them at home and it takes 30 minutes twice a week. You will feel the results in less than two weeks. Most of the people who run consistently do those kind of exercises because running is very demanding on your body and if stabilizer muscles are weak, the impact will go to your joints and tendons.

yeah, it is great that you've read a book or two, but why is it that every single elite athlete runs and trains in modern "springloaded" shoes?

Is there a way to find "the concerns" of people from back when MS Excel was becoming a thing? Maybe someone here can share how people took the introduction of the early days "productivity tools" like MS Word and MS Excel?

Mine was automating mining ore via an assist tool called UOInject. I think the language there was Visual Basic. I started programming purely out of necessity.

> So what happened to the Swiss watch industry is not merely an interesting outlier. It's very much a story of our times.

I am not saying it is, but it sounds like the first paragraph of every Gemini deep research.

I thought that's called "hangover" and you just need to drink more when that happens.

I like it because it differs a lot from whites and reds and allows to get a different perspective on how wine can taste. While the difference within whites and within reds can be huge, the orange wine tastes like something completely alien, yet it can be very tasty.

There were not a whole lot of Russian tourists 10 years ago because the memories from Russian invasion of 2008 were still fresh.

I'm not saying that inflow of Russians is particularly bad, it just raised the prices of everything very significantly, and together with the pro-Russian government and reversal in pro-European development, the European tourist influx is stagnant at best.

I've been to Georgia 10 years ago and there were a lot of tourists from Germany and France. Both the buses with organized trips for retired people and youngsters renting AirBnbs for cheap.

The problem we faced was with the inconsistency in price/quality in restaurants and services. Some places are really cheap - a huge dinner for two in a "I want this, this and this and two bottles of wine" manner costed 25EUR, while a 15 minute transfer could cost 50EUR. This inconsistency is something that leaves a bad aftertaste for many tourists, who would otherwise want to go there again and again to enjoy the beautiful nature, food, wine. And the tap water is literally Evian. That was in Kutaisi.

If it wasn't for the sudden grab of power fueled by Russian money and the influx of people fleeing from Russia because of war, give Georgia another 10-20 years, and the living standards would rise dramatically. Similar to how it happened in early 2000s.

There are a lot of Georgian wines in EU. Especially the recently popular orange wines(white wine made like red wine).

God damn it. Can people write interesting articles in NORMAL writing style nowadays? Why is everyone writing in these stupid short "punchline" sentences?

I started working on a simple Telegram bot with llm backend and .md knowledgebase that would help me organize, track and research my long-term hobby projects.

The problem that I am repeatedly facing is that I am trying to build a home server and I keep asking chatgpt questions, but it is hard to keep all the little details in one place. The way I see it is that I can just text my assistant bot and ask it something like "hey, can you research which NAS setup would be the best for me given x and y". It will offer some setup and I would say "can you add it to the plan" and "can you plan the next steps for me?". The bot will also update the knowledgebase and version control it.

You might also want to use it for something like planning a trip to Paris, where at some point you might say "hey, given my schedule, can you squeeze a tour to top5 croissant places in the center of Paris".

The whole thing sound really vague and sounds like something solved long ago, but I cannot find solutions that will be guaranteed to stick to a very precise plan that I can review at any given moment. If you happened to know existing solutions, please let me know. I really don't want to build this thing.

Great article!

On a sidenote, what is this new style of writing using small sentences where each sentence is supposed to be a punchline?

"And most of those sequences? They don't fold into anything useful. They're junk. They aggregate into clumps. They get degraded by cellular quality control. Only a TINY fraction of possible sequences fold into stable, functional proteins."

Ask HN: Has anyone properly set up LLM programming workflow?

penetrarthur — Fri, 21 Nov 2025 17:22:00 +0000

With new LLMs being released almost daily at this point and with availability of all the possible "spec-driven" workflows(BMAD, AgentOS etc), is anyone really developing production ready software with little to no intervention? I have talked to a lot of software developers in my circles and most of them are using LLMs for autocomplete(which has gotten extremely good with Augment code and others) or attempting to "one-shot" some small features. I keep reading that many people are writing 10k lines of code daily which quite honestly sounds plausible. What I don't understand is whether that code is maintainable, modular, performant and otherwise production ready. I believe that with proper specs and setup, modern LLMs can do all that, but I have yet to hear real life examples of that.

Any information on how comfortable the strap is? I am wearing a Garmin HRM Pro for one hour a day during workouts and it is not very comfy. I know a lot of athletes are moving to way less precise optical hand straps just because of the comfort issues with chest straps. I would not wear a chest strap for longer periods of time, unless I absolutely had to.
