dnadler··on Banks lose billions in value after tech lender SVB stumbles
Well, to be fair, by the time 'everyone knew' it was too late to hedge.
dnadler··on Introducing ChatGPT and Whisper APIs
This is exactly right. It's cheap, but not as cheap as people think. Conversations get exponentially more expensive with message length.
dnadler··on Show HN: Flappy Bird and Wordle
Good god. This is absurd. Congrats!
dnadler··on A History of the FFmpeg Project
I feel like asking people to compile it to have fewer options would be a lot more complicated than just having them run it with the options they need, no?
dnadler··on Ask HN: What have you created that deserves a second chance on HN?
I made a retirement simulator: https://thetortoise.io

I was frustrated by the simplicity black-box style of other tools, so I built this as a hobby and then decided to publish it.

I think The Tortoise gives users the most control over the simulation, though it may have a bit of a steep learning curve. It also has the ability to quickly compare different scenarios, and is able to condense the results into some fairly easy to digest charts.

dnadler··on Nationwide FAA weather reporting outage
That's basically the entire point of Congress
dnadler··on Django Styleguide
We do this manually along with a pydantic as a middleman between Django and TS. Works pretty well and is not a major inconvenience to keep things aligned.
dnadler··on Automating heating with Home Assistant
So, I made a raspberry pi into a smart thermostat with remote sensors all over my house which allowed me to do all kinds of targetted heating, averages, etc. Turns out that Ecobee makes one, and it's quite good. Been happily using them ever since.
dnadler··on Caroline Ellison, CEO of Alameda Research, pleads guilty to seven offences
It wouldn’t need to be cash per say, just cash or very liquid and low risk assets like USTs. The yield on treasuries isn’t high, but given the volumes at play it’d generate a lot of cashflow.
dnadler··on Don't force users to register before they can buy (2015)
Not quite sure what you mean, wouldn't an A/B test be able to answer questions like these pretty easily?
dnadler··on I Asked ChatGPT to Explain Some Jokes to Me
Something I just realized here is that ChatGPT seems to be the first time that users are able to "teach" the model in a similar way that we teach other people.

Maybe "teach" isn't the right word, as the model isn't updating its parameters AFAIK. Perhaps "guide" is better.

If there's a way for ChatGPT to update its weights based on these conversations, things could get really interesting.

dnadler··on After 20 years the Dwarf Fortress devs have to get used to being millionaires
Lots of talk about the financials here, so I thought people might be interested in this financial simulator I've been working on.

Here's a very simple scenario that I set up to forecast Tarn and Zach's windfall:

https://thetortoise.io/shared-scenario/72ff9de5d4f64a408f83c...

I just set it up with an initial $4m balance and a 100k annual drawdown. It uses some fairly standard market assumptions and is all in real terms.

Feel free to experiment with it, and always happy to get feedback!

dnadler··on Data behind high-functioning engineering organizations [pdf]
Ah, I can totally see how that can happen. Thanks for the insight!

Does anyone have experience working within a matrix team? It seems like an interesting idea.
dnadler··on Cops can extract data from 10k different car models’ infotainment systems
I mean, he did ask for a "typical" comment, not a popular comment!
dnadler··on Remotely unlock/start/locate any remotely connected Honda/Nissan [resolved]
I'll just address your last point, which I think is actually fairly important to think about. It's easy to assume that other people have the same knowledge/skillset as you do, or to think that things that are trivial for you are similarly easy for others.

This is simply not the case, and it's important to try to put yourself in others shoes. (As an aside - this is what I think leads to the best products.)

I've met many programmers who are absolutely brilliant in their field who do not know, nor care to learn, how to stand up even the most simple website.

Is twitter the best place for long form articles? Probably not. But as the original commenter pointed out, there are many benefits to it as well.

dnadler··on Remotely unlock/start/locate any remotely connected Honda/Nissan [resolved]
Yeah, I don't personally think twitter is the best place either, but it's unambiguously easier to type a few sentances and click "post" than it is to make a webpage of any kind.
dnadler··on Smartphones wiped out 97% of the compact camera market
> for that you need at least a viewfinder/rangefinder to compose a good shot and a physical shutter button to take a bunch quickly and choose the best one later.

I don't know if I agree with this. I've taken some great pictures on vacations, and with friends and family using my phone. I have some of these framed around the house.

I don't think the average person is capable (or really cares that much) about getting the perfect composition. For these people, a phone is a great substitue to a compact camera that would have been used 10+ years ago.

Oh, also most phones have a burst mode that works great.

> can't be troubled to run a website

Yes, that's right. They have more important things to do than worry about hosting a website. They rightly use third party applications to disseminate information.

dnadler··on Map of the Universe (Johns Hopkins University)
Yes, at the largest scales there are large structures composed of galaxies with voids between them. At smaller scales, we can observer large clusters of galaxies.

See, for example, Galactic Filaments [0]

Really cool stuff!

dnadler··on Hyundai’s Ioniq 6 EV makes its US debut
Well, those trucks would kill a lot more pedestrians if their brakes didn't work, so...
dnadler··on Galactica: an AI trained on humanity's scientific knowledge (by Meta)
IIRC this is correct, but the model got a bit tripped on "unobservable" vs "observable"

Kind of interesting (or maybe not) that the content is good, but that kind of detail is not.

Question: What is size of the universe?

Answer: The size of the universe is a subject of debate. The observable universe is the portion of the universe that we can observe from Earth, and is estimated to be 93 billion light-years in diameter. The observable universe is much smaller than the universe as a whole, which is estimated to be 13.8 billion light-years in diameter.

The universe is the entire collection of matter and energy in the universe.

dnadler··on For its big comeback, Intel needs to spend money, and it's making less and less
It would just be a question as to whether the reinvestment would be expected to yield a high enough return. Theoretically, at least, if the dividend is being repurposed for investment and the market believes that that reinvestment will drive enought growth, then the stock price could stay flat or even go up. Especially in the current environment where there aren't many good places to invest capital.

I'd think that scenario is fairly unlikely though, and in any situation where the dividend goes away volatility will certainly go up.

dnadler··on NASA’s Webb takes star-filled portrait of Pillars of Creation
I'm not sure I see what you're describing, but it's unlikely to be gravitational lensing. That requires truly massive gravitational fields and distances to have a noticable effect (eg. large clusters of galaxies).

It's probably more likely due to gravity causing stars/dust to drift towards each other, causing clumps and voids.

dnadler··on Solo founder dilemma; CEO or CTO?
FYI, the Tutorial link in the footer of the tooljet site seems to be dead: https://docs.tooljet.com/docs/intro
dnadler··on Some New HTTP Verbs
That's a fair criticism. On the other hand, I do find it useful to be able to construct an API where `PUT /object/1` will create an object, and `DELETE /object/1` will destroy it. It helps me keep things a bit more organized that way, but it wouldn't be hard to add the verb to the end of the URL instead.

I would probably be in favor of some more strict guards around specific verbs, but I don't really know how that would be implemented given that the behavior is always controlled by the developer at the end of the day.

Web frameworks adhering to these conventions is probably a good thing, though, and in my somewhat limited experience, that seems to generally be the case (though they often still let the developer override the behavior).

dnadler··on Heavier cars are safer for their drivers, but far deadlier for everyone else
I'd think that that depends on the density of the rail network and sparsity of the destinations.
dnadler··on Heavier cars are safer for their drivers, but far deadlier for everyone else
I think you and I have different concepts of realistic, ha. How do you propose people travel from rural place A to rural place B? Public transportation? That would be extremely expensive to implement, and would operate at a massive loss to service the entire US.

The interstate system and truck delivery seems to be pretty fantastic at servicing the continental US when paired with freight trains, cargo planes, etc. And it is similarly effective for delivery of all other kinds of things including people.

These systems would be good to implement in many cities, but interstate shipping and travel is another thing altogether.

dnadler··on Heavier cars are safer for their drivers, but far deadlier for everyone else
So build an entire second interstate system? That’s not really realistic, which tends to be the problem with most ideas to move away from cars.
dnadler··on Becoming a Systems Architect
> What is it about tinkerers being put into these positions as a natural progression?

I don't know enough to say whether this is a common pattern or not, but if it is, it could perhaps be that tinkerers tend to gather a vast breadth of knowledge that can be very useful when making strategic decisions. They reach the point where they know enough to understand what questions to ask on many topics, even if they are an expert in only a few (or none) of them.
