Great Q--it's weird that Apple, Snowflake, and the other big contributors have put essentially zero calories into documentation/website/etc. There has been some movement lately, th…

They say, "our goal here is to improve PostHog as a product for our customers, not to expose or sell models trained on your data" but then don't actually list that as a limitation …

Simple answer: There is no physical basis, it's style Pedantic answer: Unless the light source has different colors on different sides Complex answer: Kind of. Even a linear color …

As a boss-man myself, I’ve seen this “don’t let them take advantage of you” sentiment expressed in many discussions about comp and promotions, but I can’t really say I understand i…

RTM was my TA at MIT for a CS/systems engineering course. It took the students until we did an assignment about the worm to realize who he was IIRC. The students thought it was ver…

Neat visualization. There is a street performer in my town that has them all memorized (and many international zip codes as well) and makes a fun show of it, asking people what zip…

Sure, let's take a rug as an example. I don't think there is one breakpoint. I think there are a set of axis of quality you invest into, roughly sequentially, as you go up the pric…

We thought of that demo with like a week or two to go before the event when we realized we needed something more visceral than a blinking cursor :) So, it stayed with the world bec…

The documentation is woefully out of date, sadly. Despite the code being in active development no one is touching the public docs. Though I don’t know for sure, that limitation was…

Ha, well I met Scherer ~30 years ago in a high school math class and we’ve done three companies together, so you could say we’ve known each other for a bit :)

Well, I stand very much corrected since that's me in the video! I forgot that an early version ever made it out into the world.

It looks like it might be knobs (which can be changed via config file) called MAX_WRITE_TRANSACTION_LIFE_VERSIONS and MAX_READ_TRANSACTION_LIFE_VERSIONS now (defined in ServerKnobs…

You might be able to , but are definitely not supposed to. The client is conceptually "part of the cluster".

There have been some 3rd party toy projects in the past years, but pretty sure nothing was ever released by FoundationDB/Apple relating to SQL (until this additional SQL interface …

Thanks for the insight. A $XX million exa-data system is no doubt impressive :) > Another big problem I found with modeling real apps was the five second transaction timeout. This …

FoundationDB's original promise was to combine a distributed storage engine with stateless layers on top to expose a variety of useful data structures (including SQL). The company …

I was curious to see how audible square wave duty cycle would be (I figured not much) but sadly the audio examples are clearly broken on this page--choosing the same one multiple t…

Huh, I was actually on this page a few years ago, but iOS and MacOS quality has been super solid for me this past year. Anyone else feel this way? Judging by the nodding comments m…

You were talking to a slightly earlier company--this was post Viaweb.

I worked with pg in a three-person startup in a basement in Harvard square just before he started YC. I was an undergrad at MIT and met him after arguing with rtm (who was a TA for…

Interesting article. I would have loved to see the quality ratings weighted by how many people drive the roads, not by road-mile. I bet it would look a lot worse. It seems like low…

What no-one is pointing out is that LLMs have made almost as much progress on the first part of the request as the second! ChatGPT writes me a is_point_in_national_park function an…

That class scheduling one is a good place to grok the basics. Just extending the kind of approach introduced there will get you decently far. The best resource after the tutorials …

As a FoundationDB partisan, it's been great to see more and more people starting to build stuff with it. Someone recently told me that they think of FDB as "assembly language for d…
