Putting aside the details of the product itself, I love the style of this post. I wish more announcements read like this.

Is the main point “let me mathematically prove that it’s impossible to do what I’ve already done 12 times this year?”

Yes, very long workflows with no checks in between will have high error rates. This is true of human workflows too (which also have <100% accuracy at each step). Workflows rarely have this many steps in practice and you can add review points to combat the problem (as evidenced by the author building 12 of these things and not running into this problem)

This looks very cool, will try it out on my next project.

There have been a number of solutions popping up to address this problem, and I think the need is very real. Decomposing these LLM tasks into subtasks seems to be one of the best ways to work around the shortcomings of LLMs in production apps (hallucinations, context window limits, etc). But then you end up with complicated pipelines that are difficult to debug, improve, reason about, etc.

He’s a couple days unemployed and is already producing code that looks like it’s meant to teach people. Very happy to see that! The world will be a better place with more Karpathy educational content.

Can you walk into any NY retailer and do this? Or is it up to the seller whether they support it?

We're having issues as well

I'm very happy to see that someone is working on this problem!

At my last startup we had a lot of pain points around financial modeling, and it felt like 80% of the work we were doing in our models was the exact same thing that every other startup was doing, all so that we could model the last 20% that was truly unique to our business. It was also very hard to keep these models up to date, test out multiple scenarios, share models with investors without them immediately going stale, etc. I think there's also a great opportunity for you to look at the data from different startups in order to help give guidance re: best practices (e.g., "80% of startups in your category have a lower conversion rate than you - consider adjusting your expectations").

I've actually considered working on this problem myself, but TBH I have some concerns about the business model (e.g., I think it's going to be challenging to get startups to pay a significant amount of money for this on a recurring basis). I'm happy to see that someone is working on it though, and I'll be rooting for you guys!

There's a reason these scammers choose gift cards as their preferred way to get your money: gift cards have become the easiest way to move large amounts of money while minimizing the chances of getting caught.

Every other business that deals with the transfer of money (banks, for example) is expected to put strong measures in place to make sure that the money is traceable and that they're not helping criminals. Why shouldn't large companies like Target be held to a similar standard?

Moreover, the incentives here are very worrying. Yes this guy got scammed out of $3k, but Target also got $3k in revenue. Without some sort of penalty/punishment, Target is incentivized to do the bare minimum to minimize their PR exposure (which they can do by saying "we take this very seriously and have adopted some new policies" but not really acting on it) but to otherwise allow this to keep happening. As the prevalence of these gift card scams has skyrocketed, so have gift card sales for these large companies.

Hey - I'm the author of the article. AngelPad's terms are pretty similar to YC's old terms: ~7% in exchange for a small investment, plus a more substantial convertible note.

$8 just gets you the band (the colored part). Looks like it's $39 for a whole unit (the vibrating part + band)

See my comment below about what we were expecting

We were hoping that they wouldn't mind since we made it very clear that we were not affiliated with them.

Yes, it's true, they probably would not have cared as much if we weren't using their name and referring to their logo. But ultimately we were a service that sold Amazon gift cards, so it was always going to be up to them if they wanted to let us continue to exist or not. We decided to give it a shot and see what happened.

It's mostly because we used their logos. It didn't help that they had just released Amazon Coins themselves...

We allowed you to buy Amazon gift cards with Bitcoins

It looks like everyone is halting trading (at least MtGox and CoinBase are), so you probably won't be able to for a while.

How could this possibly result in Bitcoins going up? Even if this is handled without any hiccups, this should shake a lot of people's faith (myself included).

This should be a wakeup call for anyone that thinks that Bitcoins are totally secure. What if next time the bug in the client is more exploitable? Someone malicious could potentially take out the entire Bitcoin economy in one day by exploiting it.

Same for me, but HTTPS seems to be much slower to load for some reason

That is something we'd like to do eventually, but this seemed like a good place to start.

Fun challenge. It took me about 10-15 minutes using curl.

I think it's the right level of difficulty: Difficult enough that you're able to weed out a lot of really low quality applicants, but not so difficult that you run the risk of excluding high quality applicants.

After spending a ton of time trying to think of a name for a web app, I spent a couple hours writing this short domain name generator. It's a bit buggy and it doesn't generate the world's greatest names, but it's something.

http://shortdomains.heroku.com/

Sounds great! I'd love to be able to register for a gmail account and then immediately be able to start processing incoming mail.

I'm not sure why everyone's focusing on the name, but this looks like a great project. I was just wishing that something like this existed yesterday, and poof, here it is. Great work! My only suggestion would be to support imap/gmail integration and the like without requiring an extra step such as getmail.

I'm surprised that people don't seem to like this as much as I do. Yes, a designer is obviously going to use a more powerful tool, but that doesn't really say anything about how useful this is. I'm constantly writing small web apps and I have absolutely no design sense whatsoever. Having a really simple, elegant tool that lets me randomly choose a color and view a few shades lighter or darker is a huge help. It's got a nice, simple UI and does one thing very well. I'll definitely be using it.

And for those of you linking to other tools, they all either a) have a poor UI or b) do too much. That's not to say that they don't have their place, but they just don't do the same thing as this.

I would definitely be interested in watching this, and I think the amount of feedback in this thread shows that others would be too. If you look at the Feedback section of railscasts.com you'll see that the second most popular request is for Ryan Bates to "Build an entire application over a series of screencasts" and it has almost 1500 votes.

Others have already pointed this out, but it's important to keep the screencasts short and try to split each project up into smaller videos by topic. I like screencasts, but there's nothing worse than sitting through an hour long video for 10 minutes of content. It's a waste of time, and it makes it difficult to find the valuable content again later without re-watching the whole video.

I'm currently taking one of Matt Blaze's courses at Penn (Operating Systems). It's cool to see one of my professor's papers posted on HN. If you liked this one, he also wrote another cool paper entitled "Cryptology and Physical Security: Rights Amplification in Master-Keyed Mechanical Locks." It discusses the ability to reverse-engineer master keys in the context of computer science. Here's a link:
