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 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. :)

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.

I posted here on HN but it got removed.

jedberg··on GPU World
Ha! They must run Pangram. It probably flagged the comment.

No it isn't. I've put human written material in there (my own unpublished material) and it says 90%+ AI. Then I put some AI material in and it said 30% chance of AI.

I only tested it with the two pieces, but was not impressed.

jedberg··on The safest job from AI may be writing
I'm curious if you've tried Claude. Subjectively, I've always preferred Claude's writing over ChatGPT and Gemini.
jedberg··on Launch HN: Almanac (YC S26) – AI that knows your company
> Currently we don't allow for multiple model selection, but it is on the roadmap.

Cool! What model does it use now? Enterprises will definitely want to know.

And the other big question: Why not just use Claude or Codex (via CLI on a desktop or droplet)?

jedberg··on Launch HN: Almanac (YC S26) – AI that knows your company
There is a lot of competition in this space, both commercial companies and open source. It seems like the biggest advantage for using one of these and not Claude or Codex is that you can use multiple models. Otherwise, those two have all the same features, or probably will in the next week.

Are you able to use multiple models? Or I guess the first question is, what model(s) are you using? At this point, many enterprises care so that should be front and center, especially if you're using models hosted in China, because a lot of non-Chinese companies care about that.

You mention some things about unique ways to store memory. Do you have any data or use cases on how that improves performance? If you do, you should get those on your website too.

I'm not sure you have a very strong answer to "Why not just run Claude or Codex on my laptop?" Sure, you provide compute, but so do they, and most enterprises and even regular people are getting desktops/droplets to run their agents now because of this problem. This is kind of solved already.

Also there is a small nit with your website. The graphic next to "Proactively gets things done for you" gets bigger and smaller, so if you're trying to read anything below that, it keeps jumping up and down.

jedberg··on Calibrate Before You Accelerate: Bias Toward Action in a New Role
My last few jobs I started with a listening tour. I talked to everyone who was relevant to the job and asked them:

- what is going well,

- what is not going well

-what do hope that I will fix

-what should I do

-what should I not do

I put those question in the agenda for the meeting invite so they could come prepared. Then we took the conversation from there.

I put it all into a google doc, then synthesized it into summary that hid the identities of the people who said it and used it as my guide for the first few months.

jedberg··on Afterglow: Run classic After Dark screen savers on modern macOS
That's a good point. The other examples didn't involve copyright.

Hopefully since it's so old, the copyright holders are cool about it.

ps. Hi Seth, good to see you around!

jedberg··on Afterglow: Run classic After Dark screen savers on modern macOS
This is pretty well trod legally. By the user taking a specific action, it makes the user responsible. Comma.ai uses the same technique. Technically their self driving hardware comes with no software. You have to click a button and point it at their GitHub to get the software on it, but it's automatic after that.
jedberg··on Nvidia projects $673B in sales as AI demand widens
Remember, Nvidia sells services too, not just GPUs. They also sell full racks of servers. This is just sales, not profits.
jedberg··on AWS Acquires DuckLabs
Amazon is actually pretty good about open sourcing core technologies like that. Firecracker is a big one. They also support Valkey and pay some of its maintainers.
jedberg··on Starbase, LA
> His companies have made many monumental engineering achievements at his direction.

If you know anyone who has worked at one his companies, especially at a high level, you would know that they made those achievements despite his directions. The SpaceX team was ecstatic when he bought Twitter, because it meant he would be around a lot less.

The policy at SpaceX was basically avoid Elon, and if you had to talk to him, just agree to whatever he said and then not do it. He almost always forgot by the next time he talked to you, and if he didn't, you just said it was really hard.

Since he doesn't understand rocket engineering, it was pretty easy to get away with that.

And the people who worked with him at PayPal would tell you that he knows nothing about software engineering and they basically threw away everything he wrote, but they had to be nice because he had a lot of stock after his company was acquired by PayPal but called a merger.

Elon's main skill is marketing himself. He next best skill is marketing his companies' jobs to talented people and getting them to agree to work there.

That is certainly a critical skill for a CEO, but he is not a great engineer.

jedberg··on New Mac Studio with M5 Max and M5 Ultra
They must have fixed it because I drive my two main monitors from a dock connected to one port and then my 3rd monitor from the other port. Been set up this way for at least two years now.
jedberg··on New Mac Studio with M5 Max and M5 Ultra
Yes but if your debate is desktop or laptop, you're probably not looking at anything but a pro.
jedberg··on New Mac Studio with M5 Max and M5 Ultra
My M1 Pro drives 4 screens no problem. The trick is that you can only attach two through one Thunderbolt port, so you have to attach the 3rd one via the other port instead of your dock. (The 4th screen is the laptop's built in screen)
jedberg··on How Universities Should Prepare Founders
There used to be a class at Berkeley that was cross listed between the CS department and the business school. When you were in the class, the CS kids and B-School kids were teamed up, and the B-School kids would write the business plan and product description, and the CS kids would make the prototype.

Then they would pitch in front of investors with both. Sometimes the ideas got funded and the kids would actually keep working on them.

jedberg··on AI boosted homework scores, then exam scores dropped: study
> what's going to stop the average lazy student from ignoring whatever harness the university recommends and instead use an unrestricted LLM, thus learning nothing?

Nothing until they start failing exams and maybe seeing the error of their ways. My suggestions wasn't for you, it was for the smart student who wants to use AI to enhance their learning but not have it do all the work.

But cheating isn't new. People have been cheating in school for centuries. It's easier now, but the consequences were always the same. At some point the chickens come home to roost and you pay the piper.

jedberg··on A week of using Codex more than Claude
Claude assumes humans won't look at code anymore. The comments are for the next Claude that comes in to change something.
