dnadler··on I kind of like rebasing
Really?

I certainly have used commit messages and seen others do the same. Perhaps this is more an indictment of the quality of the commit messages than anything else.

In my experience, rebase and squash makes it easier to collect work into meaningful groups and thus write more helpful/informative commit messages.

I can think of a few times off the top of my head when I referred back to a detailed commit message in a repo to understand why a change was made.

And until recently, a helicopter :)
dnadler··on How Python asyncio works: recreating it from scratch
In the workflow example, is ` Purchaser.purchase` supposed to be `do_purchase`?
dnadler··on Rapier is a set of 2D and 3D physics engines written in Rust
Thanks for posting this project! I’ve been curious about wasm with rust and I found your code to be really easy to follow, and gave me a really good idea of how I could get started with a similar project. Kudos!
dnadler··on Gemini AI
Unrelated to the content of the announcement, but the scrolling behavior of the 'threads' at the bottom of the page is really neat.

I'll need to look into how that was done - I've seen similar things before but I can't think of any that are quite as nuanced as this one.

dnadler··on New models and developer products
This might also be a bit easier than it seems. I've done similar (though not nearly as nice of a UI) with `unstructured`.
dnadler··on With mortgage rates soaring, taking over existing mortgages is gaining steam
Why would that be the case? A low rate mortgage has some value, so I would expect the buyer to pay more for the house as a result.
dnadler··on Ask HN: Show me your half baked project
Maybe a little more than half-baked, but I wrote https://thetortoise.io

It's a monte-carlo powered retirement simulator. I use it from time to time to do my own planning. I thought people would like it, but I think it's a little too complicated for most people.

I think it's pretty neat though - the best part is that it lets you do what-ifs and compare different scenarios, so you can see how financing that addition to your house compares to paying cash, for example.

I haven't worked on it in a while, but might circle back around to it in the next few months.

dnadler··on Microsoft is bringing Python to Excel
Likely a gross underestimate, given all the financial (both investment and risk) modeling done with excel.

Thanks for your work on that! I use custom JavaScript functions to hit our internal analytics API. It was really nice to work with.
dnadler··on Job Corps: free, residential training and education for low-income young adults
I did — that’a ultimately why I decided it was legit.
dnadler··on Job Corps: free, residential training and education for low-income young adults
Thanks for the information. It sounds like an interesting program. The FAQ you mention does do a good job of answering these questions. I wish that was more front and center instead of at the very bottom of the footer.

My comment was more about the fact that the "What Is Job Corps" page is very much a marketing page, and I think it leans too heavily in that direction. I bounced off it pretty hard because it's quite busy and clearly trying to sell me something. That's a red flag for me when I'm looking at education programs.

I had to do a triple take to make sure this was actually a federal program and not a scam.

dnadler··on Job Corps: free, residential training and education for low-income young adults
I have to say, the "What is Job Corp?" page does not directly answer the question at all. It sounds like some kind of school?

Do students pay tuition? Is it free? What do they learn? How long does it take? Where is it?

dnadler··on June Inflation Drops to 3%
Obviously there's a lot going on here, but one major factor is going to be discounting future earnings. Lower inflation means lower interest rates which means that the present value of future money is higher.

So, in other words, growth is more valuable when rates are expected to be lower.

dnadler··on Functions and algorithms implemented purely with TypeScript's type system
I feel like that’s supporting the parent, right?
dnadler··on NASA’s Mars helicopter is somehow still flying
Is that actually true?

As an example, curiosity cost about $2.5B [0].

It was flown on an Atlas V 541 which costa about $150M to launch.

So it looks like development and operation of the rover is FAR more expensive.

A follow on question to this that I've wondered is if they reduced the reliability of some of their probes, would they be able to build more of them? Could they send probes/rovers to additional bodies more quickly?

Obviously the flip side is that some probes will fail.

I expect they are not operating at the most efficient use of capital (if measured in probe lifetime/$). But since they are funded by the government, the politics mean that failure, even within expectations, would result in reduced funding.

So maybe this overbuilding is a symptom of government inefficiency?

dnadler··on Turnstile: Cloudflare’s Smart Captcha Alternative
With all the captchas and human-verification screens showing up, I thought this was a pretty interesting and timely product.
dnadler··on Writing a chat application in Django 4.2 using async StreamingHttpResponse
I’m using this for an internal ChatGPT UI clone and it’s working great.

The actual biggest pain for me has been the front end handling of it with the fetch api. But that’s likely just due my inexperience with it.

Good point. The flip side is that allowing anyone to transact in options makes the pricing far more efficient.
dnadler··on SoftBank-backed pizza startup shuts down after raising $445M
Wait is this really an issue? It’s not like it’s some petroleum product, it’s always some kind of vegetable oil, right?
dnadler··on Meta has started its latest round of layoffs, focusing on business groups
On the other hand, the open source work done by meta has been instrumental in advancing many technologies and techniques. Machine learning via PyTorch being a prime example.
dnadler··on US Government Sells $215M in Silk Road Bitcoin, Plans to Dump Another Billion
Dollar or vol neutral? Those two assets have dramatically different characteristics.
dnadler··on BabyAGI: An Autonomous and Self-Improving Agent
Less than 3 hours is impressive, but it took me less than 10 minutes to do the same with Chroma.
dnadler··on Django 4.2 Released
Wow this is really cool. Will definitely be taking a close look at this tomorrow!
dnadler··on Please delete 2M files to continue using your Google Drive account
I had to deal with this a while back and I recall finding some Google scripting thing that allowed me to delete chunks of emails at a time. I don’t recall exactly what it was though :(
dnadler··on I asked GPT-4 to encrypt an input, and it worked?
That's the full context I gave it. JWT.io verified the signature as correct when I gave it the secret that I provided to GPT4

Actually, nevermind. jwt.io changed the signature in the JWT when I copied in the secret. So, chalk this one up to user error.

Twist, GPT-4 wrote the blog and hallucinated the URL for the waitlist!
dnadler··on Three Million U.S. Households Making over $150k Are Still Renting
That's because home ownership in the US is (was?) really the primary path for the middle class to accumulate wealth. The US home mortgage as a financial instrument is phenomenal for this.

So, it was generally expected that most people would rent until they can afford to buy on their path to accumulating wealth. There are certainly reasons for people not to buy, but not being able to afford a home is more of a problem now than it has been historically (obviously). This has significant knock-on effects for individuals and the broader economy.
