robbie-c··on Watching o3 guess a photo's location is surreal, dystopian and entertaining
Probably not, see https://www.anthropic.com/research/reasoning-models-dont-say...
robbie-c··on What if football championships were lineal?
It’s irrelevant in terms of the transfer of the title, but it might affect who gets to challenge the current champion. E.g. the opportunity might go to the competitor who’s won the most matches since they last fought the champion. Or it might go to who they think would sell the most tickets to the title match, and winning your previous matches would generate that hype.
robbie-c··on Partnering with the Shawnee Tribe for Civilization VII
That’s one way to measure it, sure. Another way is that archers can shoot 2 tiles away.

Part of the abstraction of the game is that the map for cities and the map for units are at different scales (despite being the same map), and scales change depending on what year you’re in

robbie-c··on Sid Meier's Civilization VII
Both 5 and 6 were quite weak titles on launch, and they improved massively over many years. It seems like the starting point for 7 matches this trajectory.

There is some criticism that features have been removed to be re-added as DLC. I wonder if this is just that it is really really difficult to make a great strategy game, and putting out an imperfect title and iterating is the only way we know how.

Can you explain how your link supports your argument?

The conservatives ran austerity-based policies for the last 14 years. Is your argument that they did not have a choice?

end of ZIRP
robbie-c··on A 94x speed improvement demonstrated using handwritten assembly
Yeah, I wrote my CS dissertation on this. It started as me writing a GPGPU video codec (for a simplified h264), and turned into me writing an explanation of why this wouldn't work. I did get somewhere with a hybrid approach (use the GPU for a first pass without intra-frame knowledge, followed by a CPU SIMD pass to refine), but it wasn't much better than a pure CPU SIMD implementation and used a lot more power.

robbie-c··on Vulnerabilities in the Feeld dating app
Sexual preferences and such are special category data, and if you are an engineer dealing with this stuff you should treat it as though data breaches could get someone killed.

Sure, part of the responsibility of this is on management, but it's absolutely on the engineers too.

robbie-c··on Why won't some people pay for news? (2022)
Is this related to what almost killed CollegeHumor/Dropout? IIRC facebook were lying to them about how well their facebook videos were performing, so they hired a large team based on that ad revenue. When them + advertisers found out that facebook were lying, they had to let go almost everyone apart from a skeleton crew.
robbie-c··on ULID: Like UUID but Sortable (2019)
You’ve maybe not had a use case for sortable uuids, so I can provide one:

Columnar databases like Clickhouse don’t have the kind of indices that you’d be used to if you only used OLTP databases like eg Postgres. Instead, you essentially get one index per table, which is the order that things are laid out on disk*

The problem is that you might want 2 access patterns, one for aggregating data within a time range, and another for looking up / joining data by its ID. So which do you use as the index? Timestamp or ID? If the ID is a uuidv4 and you index by ID, your time range queries need to scan the entire table, and vice versa. If the ID is time-sortable (eg uuidv7), this stops being a problem, and you don’t need some kind of workaround*

* it’s a little more complicated than this but that not in a way that affects the example

* eg a projection of your data with a different index

robbie-c··on Sam and Greg's response to OpenAI Safety researcher claims
> I'm not sure of the structure of what they signed before and this article doesn't get into it, but I maintain that there is no legal mechanism to tell someone "sign this or I take away something you already received". There has to be more to the story than the way I've seen it presented so far.

It's in that whole collection of tweets, but essentially the contract which you sign on joining says that if you leave and you don't sign the exit paperwork then you lose your equity. You aren't told what is in the exit paperwork at this point.

When you leave, the exit paperwork contains the non-disparagement clause.

Whether or not this is legally enforceable, no idea, IANAL. It does sound like enough of a threat that most people would just sign though

robbie-c··on Sam and Greg's response to OpenAI Safety researcher claims
Here's the link if you want to read the contract terms: https://twitter.com/KelseyTuoc/status/1791539443016536265

They've said they've never clawed back anyone's equity in practice - which is not surprising! If you're threatening people you hopefully don't have to follow through on your threats very often! That's kind of the point of threatening people no? So I don't find that statement partically reassuring.

Here's sama's tweet about how they're going to fix it: https://twitter.com/sama/status/1791936857594581428

My bar for being convinced that this has been handled correctly: the guy who lost his equity gets it back, and other people who previously left openai confirm that they've had some of the restrictive terms of their exit contract (like non-disparagement) cancelled. Additionally, people who made a fuss tell us that they haven't been penalised in terms of access to future liquidity events.

robbie-c··on Sam and Greg's response to OpenAI Safety researcher claims
You lose all your vested equity, which for people who've been at OpenAI for a while would be the majority of their comp.

robbie-c··on Using analytics on my website
Hi HN, PostHog employee here. I'm working on our Web Analytics product, which is currently in beta. It's fun to see us mentioned here :)

I should mention that we have a ton of SDKs (see https://posthog.com/docs/libraries) for back end frameworks and languages, so if you wanted to use PostHog without any client-side JS you could send pageviews and other events manually, but for the vast majority of people it makes more sense to use our JS snippet.

Hijacking this comment to share the roadmap for web analytics https://github.com/PostHog/posthog/issues/18547. It's very much in the launch-early-and-be-embarassed phase, but I would love to hear any feedback or suggestions that people have, particularly if you're already a PostHog user.

robbie-c··on Spotify will end service in Uruguay due to bill requiring fair pay for artists
It's different because if you imagine Spotify only had 2 users, Alice and Bob, and Alice listens to Indie Band X 10 times a month, and Bob listens to Megastar Y 10,000 times in a month, Y would receive almost all of the artist revenue in the current model, but in the model that GP is proposing, both artists would make the same.

Essentially A's money is going towards Y, even though she never listed to Y.

(I'm not expressing an opinion on which of these I prefer)

robbie-c··on OpenAI's board has fired Sam Altman
> Cant be a personal scandal, press release would be worded much more differently

I'm not sure, I agree with your point re wording but the situation with his sister that really got resolved, so I can't help but wonder if it's related. https://www.lesswrong.com/posts/QDczBduZorG4dxZiW/sam-altman...

robbie-c··on Two Kinds of Techno-Optimism
FYI - Garry Tan is not one of the founders of YC. He is the current CEO.

Factual inaccuracies like this make it easy to discount the rest of what you're saying.

robbie-c··on A 15 pound computer to inspire young programmers (2011)
Eben Upton spoke at my school during my teens, I remember being so impressed with him that I applied to his college at Cambridge just so that I would be one of his students. Sadly he'd moved on by the time I arrived, but I got the impression that the Pi was largely a result of interviewing so many prospective CS students that didn't already know how to code, whereas in his generation they would have been able to.

I wonder how many CS applicants in 2023 know how to code?

I would have agreed with this before the M1 Macbooks came out, but when it did it caused a big change in my opinion.

robbie-c··on A journey into the shaken baby syndrome/abusive head trauma controversy
Tough to see how else you would do it - a hypothetical murderer in broad daylight with a ton of reliable witnesses and video evidence would still have to wait for a trial, I don't think anyone would seriously say that this hypothetical person should be free until the trial happens.

Not being able to try it out with giving you my OpenAI API key is a big turn-off. I'm not doing that.
robbie-c··on Things you forgot (or never knew) because of React
It's worth thinking about where "best practice" and "state of the art" come from. At worst, it's a business that's trying to shape these things to sell their product.

In a more middle case, it's just people explaining what they did when they faced a particular problem, and how well their solutions worked. There's a cynical version of this too, where people are more focused on their employer-brand or personal-brand than being helpful.

Not to downplay the actually helpful instances of thought leadership! I'm just observing that there isn't always an easy way to tell these things apart, or to boost the helpful ones.

robbie-c··on Things you forgot (or never knew) because of React
Developers building stuff faster leads to a better user experience.
robbie-c··on Things you forgot (or never knew) because of React
I agree with you, there was definitely a fixation. The implication is that React doesn't do things the new and better way just because it's old, rather than a deliberate decision.

robbie-c··on One week of empathy training (2019)
When I broke my toe, myself and the other people in airport wheelchairs started the boarding process first, but by the time the passenger lift had gotten us all onto the plane, everyone else was on board and in their seats. Depends on the airport but obviously in this case it's better for everyone if the wheelchair users get started first, as they are on the critical path for the plane departing.
