kuczmama··on If AI coding is lowering your code quality, you're not managing quality right
That's a good idea to give more positive instructions as opposed to negative instructions. I think you've stated it well, I suppose the problem with negative instructions is that the LLM doesn't know what to do instead.

"Never re-write a helper function" vs "Always search for helper functions before writing one" the "never... " one doesn't tell the LLM what to do, so it would have to make the logical leap from not re-writing to knowing that it should search. While it's a minor leap to make in isolation, I suppose stacking many negative rules in an AGENTS.md would assume that every time it will always make that logical conclusion on what to do.

I'm curious as to what guardrails you've tried.

This is something I have been trying to get right as well. I've attempted to use lots of linting and things like strong typing, duplicate checks, cyclomatic complexity, and robust tests. However, I still happen to find issues, which requires me to look at the code (at least at a high level)

For example, I can say "Don't repeat yourself, and don't re-write helper functions" and I will even have a duplicate linter check, but inevitably the LLM will always want to re-write a similar yet slightly different helper function. Like it will always want to re-write something small like a trim() or a toString() function in every file.

kuczmama··on I trained a small transformer in 1.5hrs and it beats many LLMs
Hey thanks for sharing this. Was curious did you find the more you trained the model the more perf improved, or did it start plateauing. For example, let's say you didn't spend 67 cents, but you spent 67 dollars do you think you would get major benefits from that?
kuczmama··on 7.1 Earthquake in Japan
I'm living in the South of Japan, it was a 4 intensity where I am (about 90km) from the epicenter. Luckily there was only some light shaking and nothing fell over here.
kuczmama··on An Update on Heroku
This is a sad day. I used heroku for years (in the past).

A few alternatives to consider

- https://render.com/ - this is very close to heroku

- https://coolify.io/ - My personal favorite. It's slightly more involved, but you can run it on any hardware like hetzner and save a boatload.

This is awesome! Thank you for building this.
kuczmama··on Google banned me from Google Voice
I have been using Google voice for 10+ years, and it's always been something that concerns me. I've been worried about Google either banning me or dropping the service. Does anyone know of a good alternative, I'm happy to pay for something but the main thing is it needs to be able to work from the browser like Google voice.
kuczmama··on LangChain vs. LlamaIndex
Shameless plug: This is a podcast interview I did with Yi Ding of Llama index where we discussed some of the differences between LangChain and LlamaIndex (among other things). Give it a listen as a supplement to the article:

kuczmama··on Ask HN: What non-AI products are you working on?
That is very cool. I'm curious if you can share some of the things people are using this synthetic DNA for?
kuczmama··on Zshell
Somewhat related is "Oh My ZSH!" which is basically zsh on steroids, it's always one of the first things I install on a new computer. It gives things like new colors, themes, plugins, and more. Highly recommend you check it out.

kuczmama··on Meta AI releases Code Llama 70B
That's a good point. Are you referring to the out of date cuda libraries?
kuczmama··on Meta AI releases Code Llama 70B
Wow that's a really good idea. I could potentially buy 4 Nvidia P40's for the same price as a 3090 and run inference on pretty much any model I want.
kuczmama··on Meta AI releases Code Llama 70B
Realistically, what hardware would be required to run this? I assumed a RTX 3090 would be enough?

kuczmama··on Tokyo by Train (2016) [video]
I lived in Tokyo for a little over 3 years from 2017 to 2020, and this video brings back some really fond memories.

Here's a few fun facts about Japan's trains:

- Every single station has a different song that plays. Here is a sampling of some: https://youtu.be/470_2wt2t1o

- In the deep subway stations they pump in bird sounds to make it not feel so deep

- The trains can be paid for with a specific card called the Suica card and/or pasmo card. This can also be used as a debit card at various shops. But recently due to the chip shortage these cards have been harder to get.

kuczmama··on Ask HN: Just moved to SF. How can I leverage my new location to skill up in dev?
Welcome to California, one thing to checkout is there are a bunch of tech meetups here. I'm a co-organizer of a generative AI meetup in the south bay if you're interested: https://www.meetup.com/gen-ai/

To be fair, she also stole money from other billionaires... so the system has teeth if you steal money from other rich people

kuczmama··on Show HN: Banterai – Talk to any AI celebrity, human-like voice conversations
It works well on chrome.

This is a great implementation. Really feels like I'm looking at the future. One of the coolest demos I've seen in awhile.

kuczmama··on My Failure Resume
This is a really great list. I see that you're constantly doing many things at the same time, do you ever feel like you're spreading yourself too thin? I wonder if you could benefit from focusing on one thing as opposed to working on many things at once.
kuczmama··on Ask HN: What US bank post-SVB would you recommend?
Is there a bank you can pay to have a 1:1 backing? Essentially a vault that can do Wires, ACH, Checking, etc, but for a fee?
kuczmama··on FDIC Takes over Silicon Valley Bank
That's a very good point. I think services could include things like financial management, checking, sending/receiving fees, etc.

You're right, in this model it wouldn't be nearly as profitable to be a bank as it is now. Potentially, it could be a "public good" provided by the government, or it could be like a lot of the brokerages who provide investment services and charge a commission on top.

Also, you're right it would be very hard for banks to be anywhere near as profitable as they are now if assets are backed 1:1.

But in some sense, banking is already viewed as a public good since the FDIC is backing all of the bank deposits. So at the moment we kind of have a weird hybrid situation where banks are kind of pseudo-private, but also backed by the government.

kuczmama··on FDIC Takes over Silicon Valley Bank
What I don't understand is why do banks work this way?

Imagine you were designing the bank from scratch having no knowledge of the current banking system. How would you do it? The most obvious thing would be if a customer deposits money, you would hold 100% of the money 1 to 1 exactly how they deposited it. Then the bank could make money by providing services to their customers.

If I had to bet, most people who have money in a bank today think this is how banks work.

But in reality, when a bank receives money, a bank will take some percentage of their customers deposits (90% or so), and then invest that money trying to make a return on it. This works as long as all customers don't try to withdraw their money at once.

But when enough customers... say 10% of the customers try to withdraw money from the bank at once, since 90% of the money was in other investments, the money isn't really there, and you get a bank run.

Silicon Valley Bank is not new, the whole reason we have FDIC insurance is to protect against bank runs. As long as this is the system we follow, we will continue to get bank runs.

I feel like the entire banking system is broken because "The money isn't actually there". There needs to be a better way then relying to the government to bail out banks who make bad investments. Either a bank should be backed 1 to 1, or there should be some other way to keep hold of your money.

kuczmama··on Code Lifespan
Seems about right.
kuczmama··on Ask HN: What is your new year's resolution?
I hate new years resolutions. I feel like if you need to wait for a new year to change, you don't want it bad enough.

I remember maybe 10-15 years ago I was at the gym on December 31st at around 7pm. There was a snow storm outside, so the gym was completely empty except for me, my friend and few staff. We had a two hour good workout.

Then we came back (it was either Jan 1 or 2), and the gym was packed like I had never seen before. Every single piece of equipment was being used. The gym continued to be busy until around March. Once March came around the gym levels went back down to normal, and stayed that way until the rest of the year. Then Jan came and the process repeated...

I feel like the people who need some sort of external factor to change/do whatever, won't want it bad enough to sustain that change over time, until next year...

kuczmama··on Since mid-April, the Fed has withdrawn ~$140B of liquidity from financial system
Yeah they do. Actually they get turned into cash after each coupon payment and at maturity. But it takes time (as long as 30 years for some bonds) to turn the bonds back into cash. So this has the effect of taking liquidity out of the economy, while not making anyone any poorer.

When you take out liquidity, people's money are now locked in bonds and they can't buy anything else with that money unless they sell the bond. So this has the effect of reducing demand for other financial assets like stocks, real estates, cryptocurrency, etc in the short term.

The hope is that in the long run, the economy will grow enough to be able to support the eventual increase in the money as the bonds mature.

kuczmama··on Since mid-April, the Fed has withdrawn ~$140B of liquidity from financial system
They sell bonds. When they sell bonds, USD is converted into bonds. This has the effect of removing cash from a bank account and replacing it with an IOU from the government.

The actual account balance stays the same, but where before you had cash, now you have government backed bonds.

This is what they call "quantitative tightening".
