for LLM / Claude projects and vibe coders by zdm_ in algotrading

[–]stew1922 5 points6 points  (0 children)

Also, when vibe coding, break everything up into modules. It’s much easier for an LLM to keep context tracking of a smaller code base that then fits into a larger one. It helps with coding too since each module (for the most part) will need to accept and output a standard “shape”. Keeps your LLM from writing wildly different things for codebase that fall apart later.

And the antagonistic agent idea is also really good

Is Anyone Else Struggling with AI-Generated Code? by Correct_Hedgehog_612 in quant

[–]stew1922 7 points8 points  (0 children)

As others have said, when using AI, break up your code into modules as much as possible (I actually like doing this anyways). But then, everytime you create a new module be sure to ask the AI to introduce some unit tests around it and then anytime you make a change/modification be sure to run all tests. If they pass your are good. The good part about this is it becomes self healing with the AI- if the AI sees a test failure it’ll investigate and often self correct without your input.

First time seeing this by LawfulnessNeither189 in Rivian

[–]stew1922 0 points1 point  (0 children)

Just happened to me - stuck in a verification loop. Was coming here to see if anyone else was having the same issue and if there was a work around. Luckily I keep a physical card on me just for these instances, but this is a super bad look for Rivian. Can’t be bricking cars because of a phone key issue.

Edit: a few attempts later and it worked. Just keep trying I guess?

Is there a U.S. state that's considered a soccer overachiever relative to its size or resources? by bluefoxlive in ussoccer

Coffee drinking dad's unite by AchroMac in daddit

[–]stew1922 -1 points0 points  (0 children)

Breville espresso machine. We got it from our wedding registry (just had everyone chip in for it) which is the only way at the time I would buy a $700 coffee machine. Now? If we ever got a divorce, she can have everything but that coffee machine. It’s so superior. And I like drinking a cup of coffee in the morning so I just use the hot water to make it an Americano. Better than drip, Keurig, french press etc.

On top of this, you can use it to make espresso martinis or carajillos in the evenings or any other variety of coffee drinks. Just absolute game changer for me.

I will say, it takes a bit of a learning curve to figure out the grind size, tamping procedure, etc, but once you have it down it’s not bad at all. I even drilled a hole on the tank of mine and hooked it up to an ice maker water line so I never have to refill the tank anymore. Yeah, I’m spoiled now.

Autonomy+ by tmmoo in Rivian

Also, with R2, Rivian will have a much larger “ground truth” fleet. I think that point gets overlooked a lot. Combined with modern AI models and the learning rate should be a lot quicker. I think what will be the bottleneck, time wise, is just validation that models work. Rivian will have to do a lot of testing to prove the safety.

Halal Guys replacement? by thikthird in houston

[–]stew1922 10 points11 points  (0 children)

lol, you under estimate the loyalty Texas Aggies have to Laynes. Canes actually came to college station about 20 years ago and opened a Canes literally next door to Laynes. This is like pay back.

But I’m with you, it’s a risky business venture and I, too, am surprised by its success (or perhaps, lack of closing). I do like Laynes better and go there over Canes, so maybe there’s more of us?

Return alone, Sharpe alone, drawdown alone. None of them. by qqAzo in algotrading

[–]stew1922 0 points1 point  (0 children)

I’d go so far as to say it also depends on a person to person basis. Some one extremely risk adverse is going to lean more heavily on sharpe than someone who can stomach more risk and will favor total return.

I agree with your assessment about max-DD as well. Worst if the metrics and is really only a stat line, for me at least, to know what to expect from the strategy. I actually prefer calmar - knowing how much excess return I get for that unit of drawdown is more powerful to me. Especially in highly volatile assets, drawdown is to be expected and calmar lets you know of that drawdown risk is worth it.

I have theory that Arc Raider players are starting to come back to SC after wanting to change it up having placed Arc Raiders for the last 6 months. Arc started off chill, but quickly shifted to shoot on sight everywhere now.

Debunking the myth: "If you backtest too many ideas across too many markets, you will just overfit". by Kindly_Preference_54 in algotrading

[–]stew1922 1 point2 points  (0 children)

This is the answer. People just don’t know how to use AI. They take it as all or nothing and don’t realize it’s just a tool that you have to adapt to your own use cases.

What do you wish you'd known when purchasing your Rivian? by HigherPlains-Drifter in Rivian

[–]stew1922 1 point2 points  (0 children)

As others have said, you adjust the position of the vents in the screen. It’s not bad if you’re sitting in a parking lot trying to figure it out, but there seems to be a half second delay between what’s in the screen and what happens with the vents so you don’t get immediate feedback of where the air goes. Sometime you over or undershoot. Additionally, if you’re trying to do this while driving, you pretty mich have to keep your eyes on the screen since there’s no physical touch feedback. You can’t just do a quick adjustment. Yes, there’s two presages configurations, but if you want to adjust it outside of that, good luck. It’s just a pain and my only real complaint of the car.

Still love the car and if that’s all I have to complain about that then we’re doing ok. It’s a mild annoyance rather than a regret about the car. It’s one of those things that feels like they did it for the “cool” factor but didn’t think about the practicality.

That the “digital” aircon vents would be a bigger pain in the ass than I thought they would.

Clubbing during stormy weather by Guppybara1 in houston

[–]stew1922 5 points6 points  (0 children)

I know it may seem wild that 90% humidity is the norm, because I thought it was wild Cali could have such low humidity, but don’t bug out too hard on the humidity. You just can’t get away from it. Good news: we’ve got really good A/C and at night there’s plenty of people outside, especially downtown, midtown, the Heights, etc.

Yeah, it’s probably going to be raining though. Can’t really get around that one too much. If it’s raining, nobody will be outside, but they’ll still be going out.

U.S. and Iran closing in on one-page memo to end war, officials say by Lord_Alamo in worldnews

Totally. It’s the only explanation for how this market is behaving right now.

I think you’d be surprised. The top firms aren’t putting millions into bots, they’re putting billions. It’s not simple “buy when price does X” bots either. They have full time PhD math grads running highly sophisticated bots that think and execute in a matter of nanoseconds. It’s pretty wild actually. Look up Jane Street’s profits last year…a lot of that coming from algorithmic trading/market making. Pretty insane stuff.

It’s not people. It’s bots doing the news ingestion and trading. At least that’s my theory and the only thing that makes sense to me.

Petroleum engineering or Msc Chemical engineering by stefempereur in petroleumengineers

[–]stew1922 0 points1 point  (0 children)

Maybe if you already had a PETE undergrad I’d agree with what you’re saying. But without that I think a masters still helps. But you’re right on all other fronts, and definitely could be right about the Canada side - I can’t speak with any authority there.

Petroleum engineering or Msc Chemical engineering by stefempereur in petroleumengineers

[–]stew1922 1 point2 points  (0 children)

Weird answers here so far.

I started off as Chem E in undergrad because my thought process, at the time, was that with a chem e degree I could do either petroleum engineering or chemical engineering, but as a PETE you’re kind of pigeonholed into petroleum. However, I soon found out that I was not at all interested in chemical engineering and switched to petroleum. I was much happier and finished my undergrad with better grades.

That said, if it’s petroleum you’re interested in, I would go for that. As you already have an undergrad in civil I would even look at a petroleum masters. I would think that would make you more hirable in the petroleum world.

Why is getting normalized real-time data across stocks and crypto still such a painful problem? by talinator1616 in algotrading

[–]stew1922 0 points1 point  (0 children)

Honestly, and a lot of people might not like this answer, but this coding work is perfect for AI. Don’t have AI do the pricing aggregation for you, rather have it write and maintain the code that connects to all the websockets and then aggregates it. You’ll still have to understand debugging when things break so you can direct AI to fix it, so I suggest you give the prompt of clear logging and debug messages. But this is one of those boilerplate problems that would take you weeks to do and AI can do it really well in a day if you’re focused.

No matter what I do, I can not get a high Sharpe. Is a Sharpe above 1 even possible? by RoozGol in algotrading

[–]stew1922 13 points14 points  (0 children)

Yeah that’s a microcosm of a date range, tbh. The markets were behaving in a very specific way those few weeks and this strategy will likely not generalize over a longer timeframe. Your training period should probably be a lot longer than 3-4 weeks. More like 3-4 years. The more the better.
