chadash··on The MacBook Neo
The base model of the MacBook Air is $1099 now. That has 16GB ram and 512gb disk. And it’s a hell of a computer.

The crazy thing is we often cite an Apple Tax, but in this case, I think they actually have a cheaper product.

chadash··on The Brand Age
Yes, but Tudor's brand is "it's built by the same company as Rolex".
chadash··on The Brand Age
Apple clearly positions themselves as a premium product. There is some luxury element to it to (e.g., my friends will look down on me if I have an android), but it's not really the same as a true luxury product where brand is the main thing you are paying for. If you offered to sell me a macbook for 25% cheapr on condition that I remove the branding, I'd be happy to do so. I'm not a watch person, but I suspect that most Rolex buyers would not pay anything close for an identical watch without the crown logo.

chadash··on The Future of AI Software Development
> Will LLMs be cheaper than humans once the subsidies for tokens go away? At this point we have little visibility to what the true cost of tokens is now, let alone what it will be in a few years time. It could be so cheap that we don’t care how many tokens we send to LLMs, or it could be high enough that we have to be very careful.

We do have some idea. Kimi K2 is a relatively high performing open source model. People have it running at 24 tokens/second on a pair of Mac Studios, which costs 20k. This setup requires less than a KW of power, so the $0.8-0.15 being spent there is negligible compared to a developer. This might be the cheapest setup to run locally, but it's almost certain that the cost per token is far cheaper with specialized hardware at scale.

In other words, a near-frontier model is running at a cost that a (somewhat wealthy) hobbyist can afford. And it's hard to imagine that the hardware costs don't come down quite a bit. I don't doubt that tokens are heavily subsidized but I think this might be overblown [1].

[1] training models is still extraordinarily expensive and that is certainly being subsidized, but you can amortize that cost over a lot of inference, especially once we reach a plateau for ideas and stop running training runs as frequently.

chadash··on OpenClaw is what Apple intelligence should have been
The problem is that OpenClaw is kind of like a self driving car that works 90% of the time. As we have seen, that last 10% (and billions of dollars) is the difference between Waymo today and prototypes 10 years ago.

Being Apple is just a structural disadvantage. Everyone knows that open claw is not secure, and it’s not like I blame the solo developer. He is just trying to get a new tool to market. But imagine that this got deployed by Apple and now all of your friends, parents and grandparents have it and implicitly trust it because Apple released it. Having it occasionally drain some bank accounts isn’t going to cut it.

This is not to say Apple isn’t behind. But OpenClaw is doing stuff that even the AI labs aren’t comfortable touching yet.

chadash··on Amazon confirms 14,000 job losses in corporate division
"job losses" is BBC editorializing. They do not use that term in their letter: https://www.aboutamazon.com/news/company-news/amazon-workfor...
chadash··on J.P. Morgan's OpenAI loan is strange
The math is wrong:

> Cost: $1,000 Case 1 (90%): OpenAI goes bankrupt. Return: $0 Case 2 (9%): OpenAI becomes a big successful company and goes 10x. Return: $1,000 + 5% interest = $1,050 Case 3 (1%): OpenAI becomes the big new thing and goes 100x. Return: $1,000 + 5% interest = $1,050

The actual math is that if OpenAI succeeds, then there's a nod and a wink that JPM will land the lead role in the IPO or any mergers/acquisitions, which translates into huge fees.

chadash··on Gemma3 Function Calling
so if i'm reading this correctly, it's essentially prompt engineering here and there's no guarantee for the output. Why not enforce a guaranteed output structure by restricting the allowed logits at each step (e.g. what outlines library does)?
chadash··on Ask HN: What to do when you're out of money and can't find a job?
Why is there a 5 year gap on your resume? It sounds like you didn't sit around twiddling your thumbs... you built stuff during that time. On your resume, treat it like you were working a job and talk about what you built. Highlight your open source contributions and if possible, tie them to your resume. Sure, some people will treat an ex-founder as a negative, but many will see it positive. You only need one job.

There is definitely ageism in tech, but 39 isn't old. I'd be happy to take a look at your resume and provide advice if you give me a way to contact you. But it sounds like the issue isn't your resume... indeed you are getting lots of interviews, so maybe it's something you are doing in the interview process. Do you have a sense of where things go wrong? Are you often getting to the final stage before hearing no?

chadash··on A 10-Year Battery for AirTag
> Ten years is a very long time in tech.

Well, they certainly _might_ be functioning in ten years from now. Conservatively, you get 5 years of use out of this, which isn't bad for $15-20, depending on your use case.

chadash··on Five days a week in the office? Forget it
Obviously in practice, this isn't always true, but in general, each employee should output more than their pay, or they wouldn't be there. As an example, Exxon Mobile supposedly has profits of $899,000/employee [1]. Their average pay is probably significantly lower than that, but let's say it's $300k, so a 20% boost in productivity increases profit per employee by $180k. An increase of 50% in salary (and I don't think it takes that much to get people to work in an office) costs them $150k.

chadash··on Product management is hosting a party, not playing chess
I think that software engineering is about two things: building things the right way and building the right things.

The second one is more important than the first one. If you don't build the right product, it doesn't matter how well it scales or how it has amazing test coverage or wonderful documentation. To that end, I think that too many managers (and companies) do too much shielding of engineers from customers. If you are just given a figma mockup and told "build this", it's easy to get bogged down for a week with the details of building a search bar at the bottom of the page only to realize that the stakeholders would have been OK with a dropdown select. Better to understand the problem you are solving and the only way to really do this is to have some kind of interaction with customers. As an engineering manager, I try to encourage engineers to get on sales calls and see product demos. When you see it from a high level, you a) almost always notice things that need fixing or can be improved and b) see where the piece that you are working on fits into the larger picture.

That said, I find that many engineers don't want to get on customer calls, and usually there's room for those engineers in an organization as well. For example, "build a new video conferencing service for artists to collaborate" would be a very challenging problem (I think) that is not well defined and therefore requires deep customer understanding. "Make Google searches run with 10% fewer CPU milliseconds" is arguably a much harder problem to solve, but it's so well defined that it really doesn't need customer understanding (setting aside the initial decision about whether it makes sense to work on).

chadash··on Learning to Reason with LLMs
Only a small fraction of all future AI projects have even gotten started. So they aren't only fighting over what's out there now, they're fighting over what will emerge.
chadash··on Lesser known parts of Python standard library
> OrderedDict - dictionary that maintains order of key-value pairs (e.g. when HTTP header value matters for dealing with certain security mechanisms).

Word to the wise... as of Python 3.7, the regular dictionary data structure guarantees order. Declaring an OrderedDict can still be worthwhile for readability (to let code reviewers/maintainers know that order is important) but I don't know of any other reason to use it anymore.

chadash··on Elasticsearch is open source, again
The words of the license are "You may not provide the software to third parties as a hosted or managed service, where the service provides users with access to any substantial set of the features or functionality of the software.".

I don't think competing with ElasticSearch is mentioned anywhere within the license. If team 1 uses ElasticSearch and team 2 is developing RAG (without using ES), then that's not an issue (but only if using the most recent version of ES, since the license for the code that I fork today has no bearing on future code that ES hasn't written yet).

chadash··on Elasticsearch is open source, again
I love https://resend.com/ as an example of a website that does a GREAT job explaining what they do. Lots of companies tell you that integrating their product is quick, but with their website I can look at it for 30 seconds and understand what the next steps would be.
chadash··on Elasticsearch is open source, again
I'm pretty happy with this, since they are keeping the option to use the Elastic License. Now everyone can be happy. To me, it's weird that the AGPL is any more "open source" than the Elastic License. The AGPL requires you to publish all of your source code if you make any changes to the product; the Elastic License just says, "don't use our code to make a direct competitor to Elasticsearch". I find the former to be much more restrictive in most practical ways since the majority of companies don't want to open source their code, but very few of them plan to sell hosted search.

Personally, I do wish that there was more broad acceptance of the Elastic License. Who wants to put in years building a business and then have a competitor with better distribution take your code and compete directly with you? For me, the reasons to want open-source code are:

* If a vendor goes under, I can self-host

* If a vendor raises prices too much, I can self-host

* If there's a bug in the code that affects me too much, I can fix it

* If there's a feature I really need, I can add it

The Elastic License allows for all of the above. Seems fair to me.

chadash··on Ask HN: Imagine a world with 1Tb/s internet. What would change?
I went from 500mpbs download/upload in my old condo to 50/20mbps download/upload in my house. There are two noticeable effects: it takes slightly longer to download movies the night before I go on flights or long car trips and it takes significantly longer to push updates to large docker containers to the cloud. Everything else is more or less identical for me.

Now, maybe there'd be some novel use case that would come up if everyone (or let's say 80%+) had 2gbps internet, but it's hard to imagine that that's the big constraint for much. Maybe something like virtual/augmented reality could do more heavy processing in the cloud in that case (assuming low enough latency)?

Chrome is not anyone's default browser, but it still has dominance. People will be bothered a little under some circumstances.
chadash··on 21 More AWS Services They Should Cancel
+1 on NAT Gateway. For those unaware, you need to setup a NAT gateway for your tools inside of a VPC to access the internet. I forget the pricing, but it's way more expensive than it should be and it's a huge pain to setup. This is a service that is annoyingly expensive for hobbyists/indie-devs/people just playing around, but a rounding error for AWS's "real" customers. Just build it into VPC (a checkbox that says "I would like to be able to access the internet from my code in the VPC") and make it free or at least have upfront pricing.
chadash··on Which country consumes the most coffee?
Come on. People in Luxembourg average 5.31 cups of coffee per day? Yes, my experience is anecdotal, but I'm not even sure that the self-described "coffee addicts" who I know are averaging that much, let alone an entire population.

The vast majority of Jews made significant geographic moves in the 20th century, either from Europe/Russia or the arab world. Most of them went to North America or Israel.
chadash··on TinyPod – Apple Watch case with scroll wheel
I'm in the same boat. Want a small phone with premium features. My hope is that the next generation of iphone SE is at least on par with the 13 mini that I currently have. Otherwise, not sure what I'll do when my mini dies since the current SE is a pretty big step down from the 13 mini.
chadash··on Supreme Court rules ex-presidents have immunity for official acts
> Convictions are in the high 90%. Juries are very weak and at the mercy of powerful prosecutors.

This is a bit misleading. DAs have latitude about what to prosecute and if they don't think they can win, they dont have to bring it to court.

chadash··on Every product that you try to build is already built
If your idea solves any pain-point that some market has, then chances are someone else has thought of it. This is especially true in the consumer space, where you don't need deep industry knowledge to come up with an idea.

But very few people actually execute on ideas that they have. And even fewer successfully execute. This is why I like the advice from the book "The Lean Startup": if you think an idea is valuable, call up a product manager at the biggest player in the space and try to get them to steal your idea from you... the short answer is that they won't, because any successful company is flooded with good ideas and they have to be picky about which ones they pursue [1].

That said, people vastly underestimate the size of the market for many things and they assume that some competitor might keep them from taking off. Think of the tire market: how many people can give a good explanation of the difference between Michelin and Goodyear? Maybe 1% of people? Yet, but companies are huge. Now go to almost any other market (save for a few with network effects) and you'll find at least several competitors in the space. And if no one is competing in a space, sometimes that's a bad sign, not a good one if you are considering it.

[1] There are some ideas that are obvious, and they might already be pursuing, such as using LLMs to automate some aspect of customer service. That doesn't count as a stolen idea. Also, don't take this to the extreme. Obviously some ideas are valuable, but they tend to be things that require very deep expertise.

chadash··on Show HN: Skyvern – Browser automation using LLMs and computer vision
First of all, wonderful work. I'm gonna be using this for sure. I can think of many use cases. What would be nice though is a simple API. I send you what I need, you send me a jobId that I can use to check the status of my job and then let me download the results when I'm done.

I played with the Geico example, and it seems to do a good job on the happy path there. But I tried another one where it struggled... I want to get me car rental prices from https://www.costcotravel.com/. I gave it airport + time of pickup and dropoff, but it struggled to hit the "rental car" tab. It got caught up on hitting the Rental Car button at the top, which brings up a popup that it doesn't seem to read.

When I put in https://www.costcotravel.com/Rental-Cars, it entered JFK into the pickup location, but then failed to click the popup.

chadash··on Ask HN : Street Vehicle Speed Counter
> It seems to me that it could be selled to the public sector.

Selling to the public sector is a skill in itself. It isn't usually the best product that wins at this... it's the company that knows the most about selling to the public sector.

chadash··on More doctors are charging fees to respond to patient messages
Doctors very much charge for time. By definition, their work doesn't scale. But because of their immense training, they get to charge _a lot_ for that time.

The same is true in law. Just because you have 10,000 hours of training doesn't mean you aren't billing by the hour.

This is why there are many many doctor and attorney millionaires and very few doctor/attorney billionaires.
