Agree. I was accused twice of plagiarism by professors in college. Needless to say there was zero plagiarism involved. In both cases I wrote code that they didn't think it was likely that an Nth year college student would know how to w

Saying "a star can't do it without a team" is very silly. That's like saying "well, sure but Shakespeare couldn't have written anything with a pen". True at some level, but I think we both know in that equ

Looks very nice from the ergonomics point of view. Trying to figure out the "call stack" of a bunch of Actors communicating via promises and futures is a mess (the physical call stack doesn't match the logical one at all) and

I completely agree. I remember a similar discussion about special effects in movies. The year was 1993 and I was telling my uncle that the newly released Jurassic Park had special effects that looked completely real. My uncle was an artist

Yes, the rules of chess are simpler, which is why all this happened many years ago for chess. https://gwern.net/note/note#advanced-chess-obituary -- here is a reference about centuar/advanced chess. The source isn

"Chess engines might get better than some chess players, but none who play Chess as a craft." Do you think people in the 90s thought this? Probably... In the article, the author mentions that Chess centaurs (a human player consult

I've looked, and it doesn't seem to exist, but I still can't believe there isn't an emissive display on the market that can just emulate the look of a passive display. (i.e. match the 'white' of the display to

I think there are a lot more of these stories to come. My town (Boulder, CO) is inundated with what look like 12-17 year-olds absolutely tearing around on e-bikes. They are rarely petaling, 50/50 on helmet wearing, and often going 20-3

What you are missing is that the "tlogs" (transaction logs) actually hold the durable, fault tolerant write log. The sequencer is just a big fast in-memory data structure that checks if the many transactions coming into the system

by Dave_Rosenthal 3y ago
Yeah, read versions are just there to make what's known as "external consistency" work. That is, if transaction B starts after transaction A commits, then B will see the effects of A. The reason external consistency is nice i

The problem is that the term available is overloaded. In CAP “(A)vailable” specifically means you can keep making db updates as long as you can talk to any db node (e.g. you and a db node have split off the internet together). In every othe

I think that’s a good and really fair summary. - If you’re a developer wanting to build an application, you should really use a well designed layer between yourself and FDB. A few are out there. - If you’re a dev thinking you want to build

by Dave_Rosenthal 3y ago
That’s true, but FDB doesn’t use very much of SQLite, just a modified version of SQLite’s internal b-tree.

While I know it wouldn't qualify for the prize due to the size of the model, I'm curious how well a big modern LLM can compress the prize file (enwiki9) compared to the current record. (I guess ideally it would be an LLM not train

I took the OP not as saying that they thought women should race simultaneously with the men (no, they don't have the same power). I thought they were just advocating for the women's TDF to have the same course as the men. That is,

I totally agree with your high level point that there isn't a great SQL (OLTP, or otherwise) layer for FoundationDB. Building something like this would be very hard--but I don't think the FoundationDB storage engine itself would e

by Dave_Rosenthal 3y ago
Yes, there are definitely a lot of big companies that have used FoundationDB very hard at huge scale for many years. That said, yeah, it feels like there are also a lot of folks on HN who just jump on the "cool, fault simulation"
48.
by Dave_Rosenthal 3y ago
Yeah, that sucked for sure and we hated to disappoint people like that (co-founder here). But you have it exactly backwards. FoundationDB was never open source. There was a binary that you could download and use as a trial, or you could buy

Thank you for saying this. Having a grid-tied building festooned with solar panels has always seemed absurd to me for this reason. It would be interesting to calculate the implied "show-off value" of the solar cells that building

Don't know why the parent comment is downvoted--it's totally right. "Rent seeking" is a term of art with that doesn't at all mean "trying to get people to rent something they could buy".

I moved to CO from the bay area a couple of years ago. I couldn't tell you what created the initial imbalance, but it feels like at this point what sustains it is a simple positive-feedback loop. To generalize, when relatively liberal,

I think a cheap thermal camera would be very helpful in these situations with a relatively fast drain. A car battery is ~1 kWh so anything that drains it in a few days is dissipating on the order of 10 watts. In my experience that's ve

Came to vote for this. I have bought both 1/18 scale bashers and mini rock crawlers (*) for both my kids and nieces/nephews in this age range and they've all loved them. They are fun to play with and then when you break them

You'll get no argument from me that most software is bloated and slow compared to what is possible. (I spent a lot of my career working on making code run fast!) But it feels wrong to say that the caches are wasted. The code we write d

If you're sad about all of your RAM being eaten, you'll be despondent if you think about about your poor L1 and L2 caches--they're all being 100% used all of the time! But seriously, RAM should be used for caching purposes

Yeah, first thing I did was to try to get a feel for when I needed to hit the main engine. Executing a landing with 1 or 2 fires I can do with some regularity. Getting the boosters to 1 or 2 is very hard due to initial conditions, but 3 to

Tried to get a good landing with as few control actions as possible. For a simple new scoring system, subtract your number of control actions from your landing score: Very nice landing, amazing Score: 90.5 point landing Speed: 2.9m

Note that they also charge equally for input and output tokens but, as far as I understand, processing inputs tokens is much computationally cheaper, which drops their price further.
