Sometimes I wonder if anyone else feels there is a halo effect around certain personalities on this site. When I see someone ending nearly every comment with a link to their blog or pet project, it gives me bad vibes, as if they have ulterior motives. Especially if a majority of their blog posts are content lifted from elsewhere with minimal additions. Perhaps this is just hustle culture, and YC alum status confers immunity from these types of criticisms. Perhaps my only wish is that other voices would bubble to the top in some of these threads.
In any case I’m truly grateful for this site as a whole, the good and the bad.
TLDR: NAC is a derivative of an amino acid called cysteine, as such it is a precursor for one of the most important antioxidants in the body and it can modulate key metabolic pathways associated with good health across a variety of organs, notably for decades it has been a universally successful antidote for acetaminophen (Tylenol) overdose, it’s available over the counter but NAC is not naturally found in foods, eating cysteine-rich foods like chicken turkey yogurt etc is the next best bet.
No disrespect but paying to verify age feels absurd, let alone putting a private company in charge of what should be an essential function of the government.
How about when you turn 18 or whatever the government gives you a signed JWT that contains your DOB? Anyone who needs to verify your age can check that and simply validate the signature via a public key published by the government.
Simply grab a new JWT when you need it, to ensure privacy.
And sure, sprinkle in some laws that make it illegal to store or share JWTs for clearly fraudulent intents.

This feels like it comes from an affluent perspective, where I grew up it was trivial to acquire these things and much worse, there will always be someone’s older brother etc who will do this for $20 because he’s got nothing to lose.
Fascinatingly, the body already has a mechanism for this: fasting. One of the many beneficial side effects is rapid mucosal atrophy, decreasing villus height and crypt depth.
You can find evidence of this in the literature, but it’s absurdly understudied, because big pharma would rather sell you a subscription to life.
Fortunately there are many good people in the world, especially in the field of medicine, who want to help their patients unconditionally. So there are glimmers of hope, like some of the top cardiologists in the world going against status quo and treating patients with fasting regimes instead of surgery.
Love anecdotes like this! But admittedly I feel a bit lost, so please forgive my ignorance when I ask: why does choosing a subset of k integers at random require deduplication? My naive intuition is that sampling without replacement can be done in linear time (hash table to track chosen elements?). I’m probably not understanding the problem formulation here.
One of the cooler and lesser known features of JPEG XL is a mode to losslessly transcode from JPEG while achieving ~20% space reduction. It’s reversible too because the original entropy coded bitstream is untouched.
Notably GCP is rolling this out to their DICOM store API, so you get the space savings of JXL but can transcode on the fly for applications that need to be served JPEG.
Only know this because we have tens of PBs in their DICOM store and stand to save a substantial amount of $ on an absurdly large annual bill.

Do you have any quantitative evidence to support this?
Sincere question. I feel it would add some much needed credibility in a space where many folks are abusing the hype wave and low key shilling their products with vibes instead of rigor.
Ha made me chuckle. For those wondering seriously about this, it’s not a viable optimization because weights are not readily compressible via JPEG/DCT, and there are a limited number of these units on the chip which bottlenecks throughout, meaning speed is dwarfed by simply reading uncompressed weights from HBM.
Great exposition, loved the touch of humor. Please do the backward pass when it’s published.
As a fellow Tri Dao groupie and lucky duck who gets to build on Hopper/Blackwell clusters, I find it amazing how difficult it is becoming to write kernels that saturate GPU hardware.
When I squint, there appears to be a trend emerging across work like FA4, monolithic (mega) kernels, etc. Namely, a subversion of the classic CUDA programming model in the form of fine grained task based parallelism, managed entirely in “user space”.
Not exactly sure what’s ahead but I’m strapping in for a wild ride…
