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

jedberg··on OpenAI expands ChatGPT ads with Sponsored Agents
I'll be a little contrarian here. I've actually purchased things from Instagram ads. Because they were highly targeted and actually something I wanted once I learned it existed. It was a solution to a problem I had but never researched for a solution.

I'm guessing ChatGPT will be able to do the same for me, especially since it probably knows me better than Instagram at this point, just given all the things I ask it.

If they do it right, it will be helpful. The big question is will they do it right.

jedberg··on Salesforce Global Outage
Is it? When your internet is out for five days because your ISP takes a few days to get to you, do you acknowledge that you're now at 98.5% availability for the year, far worse than any SaaS email service?

I think people forget that those large environments are there for a reason. To make sure the service stays up in the face of problems outside your own control.

jedberg··on iOS 27, iPadOS 27, and macOS 27
That's not how it's worked in the past. They did security updates until three versions later released regardless of the hardware. What you may be thinking of is that there was some weirdness around Intel vs M series chips and how those got updates.

Thanks, appreciate the feedback!
jedberg··on iOS 27, iPadOS 27, and macOS 27
I usually use beta OSs, but I completely skipped MacOS 26 and 27, mostly because I heard terrible things about 26.

Is 27 good enough to upgrade from Sequoia? Is your answer the same when I tell you I have an M1 Pro Max?

jedberg··on Ask HN: Can we please limit the AI news flood?
Reddit's /r/programming is very well moderated, and they specifically don't allow articles about AI, unless it's programming AI. You should check it out.

You'd be surprised how many people don't know the names, only "regular paper" and "long paper"
jedberg··on Growing proof that autonomous cars save lives
I meant they aren't political in their pricing. They don't charge less or more for something because it is considered liberal or conservative.

Letter, Legal, Tabloid, and Ledger:

https://papersizes.io/us

It's bizarre and makes no logical sense.

jedberg··on iPhone Duo
Most people in the US aren't aware that everyone else uses a different size of paper. Heck, most people in the US aren't even aware that there are names for the sizes of paper we do use.
jedberg··on iPhone Duo
Same here. I wish I could just use A4 paper, but usually when I put something on paper it is to share with others, who will not have an easy way to store or process it. It has to be a widely mandated switch.

Like only allow A* paper for government forms or something that would force everyone to switch their paper handling infrastructure to A*.

jedberg··on iPhone Duo
Oh man if this is what got the US to adopt metric paper I would be so happy.
jedberg··on iPhone Duo
People don't try to type on their passport though.
jedberg··on iPhone Duo
Actually I think he would appreciate the beauty in using 1:1.4, the same as metric paper, to maintain the ratio.
jedberg··on iPhone Duo
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.

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.
