Former CEO of DBOS. We make Transact, an open source library to build reliable and durable by default applications. https://github.com/dbos-inc/

I used to run reddit.com's servers, then I ran Site Reliability at Netflix (and invented Chaos Engineering), then I worked on making Alexa faster and smarter, and then I helped build a GPU cloud.

I enjoy technology, hanging out with my daughter and son, advising and investing in startups, and some other stuff.

You can reach me at {anything}@jedberg.net, and also send me any great investment leads there!

Or you can book at meeting with me (but please tell me why in meeting request!): https://calendly.com/dbos-ceo/30min

Actually I think he would appreciate the beauty in using 1:1.4, the same as metric paper, to maintain the ratio.

One thing I love about metric paper is the beauty of the simplicity: When you fold it, it maintains its ratio. This is because it is 1:1.41, aka 1:sqrt(2)

When I saw that this new phone is 1:1.4, I instantly appreciated why it is that way. Metric paper wins again!

My wife's first question:

Will this fit in a woman's hand?

jedberg··on Growing proof that autonomous cars save lives
Car insurance companies have their problems, but pricing risk is not one of them.

We saw this before -- they used to charge people who lived in high crime areas more money. They had to stop because it turned out that those high crime areas also had a lot of poor people, so the government stepped in and stopped allowing pricing by zip code.

But the insurance companies weren't wrong about the risk -- those customers cost them more. So instead they had to raise everyone's rates to account for the fact that they (rightly) could not discriminate.

I suspect the same would happen here. That poorer people could not afford self driving, and they same anti-discrimination rules would apply.

jedberg··on Growing proof that autonomous cars save lives
Why? Insurance companies use detailed risk data. If they discover that letting you drive your own car is a much higher risk than an auto-drive, why should they not be allowed to account for that?

Insurance companies aren't political -- they charge for whatever costs more.

jedberg··on Shopify acquires Tailwind
With how good LLMs are getting at coding, running a DevTools company with both an open source and commercial component is getting harder and harder to do. It's easier every day to just vibe code the commercial part if you have the open source part.

The ones that are successful provide other services that are still hard to do, like hosting at scale, or running the open source at scale.

Basically, running something at scale is what DevTools companies need to do to survive. Hosting the open source and the data is one type of running at scale, or helping companies run the open source in their own infrastructure is another way to help them run at scale.

First batch was 2005. :)
jedberg··on WeatherNext 3
There was a lot of evidence last winter. But with the active El Niño it’s starting earlier this year.
jedberg··on WeatherNext 3
That person is probably misremembering or looking later after the update.

I pull weather data from multiple apps all the time because I’m a weather nerd and they all agree equally poorly.

jedberg··on WeatherNext 3
It's because the current administration cut NOAAs funding, which means fewer weather balloons, which means less data to make a prediction. And it means less real time updates.

So yeah, when it rains, it might take a few hours for that to flow into your weather app.

It's a direct result of DOGE.

jedberg··on Watch Los Angeles get built, one building at a time (1880–2026)
It's not only energy though. Desalination takes space, and you have to do something with the salt. Last I saw, to have enough DeSal capacity for all of California, you'd have to replace every beach with DeSal plants to have enough capacity, and then you'd still have a salt problem.

You could put the salt on boats and dump it back much further out in the ocean, but that too takes energy.

> Do you own your home? Here in Ca?

Yes and yes.

And I pay 10K less a year than my neighbor for the same value house. And I pay 10K more a year than my other neighbor.

I get a huge advantage from Prop 13, but I still think it needs to get replaced with a much fairer system.

jedberg··on The moral panic over data centres is foolish
Regulations about 95th percentile decible levels at certain distances, and regulations about max decibel levels at certain distances, for all buildings.
jedberg··on The moral panic over data centres is foolish
Trying to educate them that water and power usage are the less problematic parts and not as bad as everyone thinks. It's the noise and lack of green power that are the problems.
jedberg··on The moral panic over data centres is foolish
I'm saying the people who are affected need to lobby their own local governments, because the companies will never do the right thing until they are forced to do so.

But what people are most upset about are water and power, which are the two least problematic things about datacenters.

jedberg··on The moral panic over data centres is foolish
I don't do that anymore since I got laughed at by coworkers when I suggested we focus on using green power and reducing noise. So yes, my conscience is clear.
jedberg··on The moral panic over data centres is foolish
No, there really isn't. It's more a question of how the data center is cooled. There are quieter more expensive options, which is why they often aren't used.
jedberg··on The moral panic over data centres is foolish
No thanks, they are loud. I even called that out. But no one should be living next to them. Those people need to get their local government to regulate noise from all buildings. The companies won't do it on their own.

(This is part of why I no longer help build them, because when I asked about reducing noise and using green power I was laughed at).

jedberg··on The moral panic over data centres is foolish
I have a lot of left leaning non-tech friends. They are all very much against AI data centers. I've built AI data centers, and I keep trying to educate them, but they just won't listen.

The water is mostly part of a closed system. Sure, you need a lot to build one, but once it's running it's pretty water efficient. The lack of green power is a problem, but as the article points out, you now have a large customer subsidizing the base cost of delivery, since they are only one delivery point, and they are financing new sources of power, which if properly regulated would be green power.

The noise is an issue, I will admit that. As is the fact that a lot of the power is coming from non-green sources. But the government could easily fix these problems with regulations that apply broadly, not just to datacenters.

jedberg··on An open DNS recursive service for free security and high privacy
I've been meaning to switch my in-laws to Quad9 and just not mention it to them. They fall for too many scams, I'd love for those websites to just not work anymore.

Cloudflare probably has a server on AT&Ts network, but not on Xfinity. Google is probably the opposite.
jedberg··on Google Antigravity TOS: 3rd party usage can get Google account suspended
I actually know someone this happened to. While they did ban him from using the bank, they first warned him, gave him a chance to close out his open transactions, and then helped him move all the money somewhere else at no cost.

The important part is that they can't just close your account and keep everything.

jedberg··on Google Antigravity TOS: 3rd party usage can get Google account suspended
Sure, but they have to give you your money back. They can't just keep the money.
jedberg··on Google Antigravity TOS: 3rd party usage can get Google account suspended
Banks can't just ban you, nor just take your money. The price they pay for being gatekeepers is a ton of regulation.

This is why PayPal for the longest time made it really clear that "we are not a bank". So that they wouldn't be subject to those regulations and could suspend accounts and keep the money.

I have 1000s of reddit and hacker news comments from before 2023, and lots of long form writing too. But as you point out, those are all in the training set, and in pangram's "definitely human" training set too.

The ones that sound like LLMs tend to be the ones that were well researched and spent more time on, not the off the cuff stuff, which is most of what I write. So it would take me a while to find something like that.

But you're welcome to dive into my reddit and HN history, or all my blog posts on the wayback machine if you want to look for one. :)

jedberg··on GPU World
Here is another example: https://www.reddit.com/r/ExperiencedDevs/comments/1pyjkuf/i_...

Today Pangram says it is 100% human, which is correct. But yet I got multiple DMs when I posted it 8 months ago saying "stop posting AI slop!" in response to that comment. At the time, Pangram marked it as 50% AI.

So to Pangram's credit, they got better.

jedberg··on GPU World
It’s important to remember that LLMs were trained on well written human text. People who write well are going to sound like an LLM. Especially if it’s a marketing message for a website.

I’ve been accused of being an LLM multiple times here on HN too. I know you have no way to know for sure other than trusting that I’m not using an LLM to write. But it’s pretty frustrating that people jump right to LLM accusations.

Ha! They must run Pangram. It probably flagged the comment.
