The price wasn't that ridiculous IMO for the quality of the discovery, it generated 31M output tokens which is ~$1500 in API cost if it was on Fable. A new lower bound on the biggest unsolved problem in mathematics for less than a couple day's pay of a prestigious mathematics professor is kind of insane. Obviously this discovery doesn't change anything as it's just moving a lower bound, but that's something many mathematicians have tried and failed to do.

I think that false positives are inevitable due to the method of watermarking being embedded in the text itself. The output is intended to mimic human writing, therefore it's entirely conceivable that a human could by chance write text that contains the watermark. The odds may be extremely small, but it's not something you could ever guarantee.

Yeah you're right, I was thinking of trademarks. I just think the system is very cumbersome and antiquated, these days it mostly serves to benefit patent lawyers rather than inventors and small businesses, aside from highly regulated fields where things move slower.

That is why all patents exist. It's ridiculously time consuming and expensive to get a utility patent for anything. I invented something at my old company 5 years ago and the patent process is still ongoing, should hopefully get awarded this year. It costs tens of thousands of dollars in legal fees and you need to actively litigate infringements if you want to keep it. 99% of patents exist just for legal bullying and the other 1% are actually novel, useful inventions.

Weird, I also have floaters and snowboard but they've never bothered me that much. I can just tune them out and don't notice unless I'm looking for them. Come to think of it, this is probably the first time I've noticed a floater in years. It's probably a mental game, similar to how you can always see your nose but never pay attention to it

Really surprising that Inverness and Skye have only 16 pubs considering how much tourism the area has. I felt like it wasn't lacking for pubs but maybe I saw all 16...

Yeah, they may be over built for sure, I'm just saying the demand is there.

Always insane to me how people will just read the headline of an article and point out "flaws" based on what they assume the article says

But AI use translates directly to time savings (if it works). You only need 1-2 hours of time savings per employee per week to break even on a $100/seat/month subscription.

The thing that's a bit different about AI from a CRM is it translates pretty directly into time savings. You only need each employee to save 1-2 hours of work per month to break even with a $80/seat subscription.

New comment by jrflo in "Don't use your phone while you poop"

jrflo — Sat, 08 Aug 2026 15:25:01 +0000

This is the thing I've become increasingly radicalized about. I built an app (link below if you're curious, it's $5 [1]) to cure my particular brand of phone addiction.

I've been using my phone for probably ~1hr per day for the last 6 months and I've realized how many ills of our society today can be traced back to phones and social media. Political polarization, misinformation, mental illness, the loneliness epidemic, brain-rot - we'd be in a very different place if we could moderate our use of this technology more.

The thing I've come to realize is that when I look at my phone it's so boring now, and that's how it should be.

Might not actually be that much cheaper, we don't know what margin OpenAI is charging on Luna API. Open models likely have much less margin.

I'm using the term "one" loosely, it's a chain of exploits rather than a single weakness, but the argument is the same: it's much harder to find every chain than a single chain.

Do you really need a KV cache if inference is that fast though?

Not a security guy but my understanding is: you only need to find one flaw to exploit a system, to make a system totally secure you need to find them all. It's inherently easier to use these tools offensively rather than defensively.

This analysis calculates 80 square meters of radiator surface area needed per rack, or 200,000 square meters per 100 MW.

It's not to say it can't be done, I think orbital data centers could actually be a pretty good idea, but to say cooling is a nonissue is disingenuous. Innovations are needed there to make it work.

This is a nothingburger article, 23,000 jobs lost is essentially flat.

The Fed is not going to cut rates. Looking at Fed Rate futures they only predict increases:
