k8si··on AI companies are shredding rare books
Why is the shredding a result of the fair use stuff? I actually don't understand
k8si··on Sleep regularity is a stronger predictor of mortality risk than sleep duration (2023)
fyi, Whole Foods sells liquid melatonin. bottle says 30 drops contains 3mg so I only take a couple drops at night and it does the trick for me.
k8si··on If AI writes your code, why use Python?
because it's likely that a lot more of the training data is in python than in rust, so coding models are less likely to mess up python code? just based on PL popularity stats e.g. https://madnight.github.io/githut/#/pull_requests/2024/1 if the training data is crawled from real codebases then there's gonna be more python than anything else.

in my personal experience, the one time I tried to do something in rust, opus flailed for several feedback cycles and I finally had to relent and do substantial guiding/intervention. which was not great bc I have no idea how to write rust either.

k8si··on Claude Code Remote Control
- Plan mode -> answer questions/make corrections, continue planning

- Some of us don't do full yolo mode all the time, then tool approvals or code reviews are required, nice to do a quick review and decide if you need to go back to your computer or not

- Letting claude spin or handle a long-running task outside of normal work hours and being able to check in intermittently to see if something crashed

k8si··on MIT Professor Is Fatally Shot in His Home
I'm not sure people outside of Greater Boston would care, but those of us who do live there probably find it exceedingly strange that this occurred in Brookline of all places.
k8si··on “Captain Gains” on Capitol Hill
Well, currently we have a ton of Congresspeople who are primarily motivated by their "good financial sense" (for obvious reasons e.g. this study). So, I think we could do with a few more Congresspeople with less financial sense and more genuine motivation to improve the lives of their constituents.
k8si··on They're Killing the Humanities on Purpose
"Only rich kids should get to choose what they study in school, poor kids are too dumb to make their own choices"
k8si··on Fine-tuned small LLMs can beat large ones with programmatic data curation
Maybe this is a nitpick but CoNLL NER is not a "challenging task". Even pre-LLM systems were getting >90 F1 on that as far back as 2016.

Also, just in case people want to lit review further on this topic: they call their method "programmatic data curation" but I believe this approach is also called model distillation and/or student-teacher training.

k8si··on What happened to BERT and T5?
I believe many high-quality embedding models are still based on BERT, even recent ones, so I don't think it's entirely fair to characterize it as "deprecated".
k8si··on Show HN: Podlite - a lightweight markup language for organizing knowledge
Please put concrete examples right at the top of the page you're publicizing!
k8si··on Launch HN: PointOne (YC W24) – Automated time tracking for lawyers
Is it actually more feasible now? Do LLMs actually make this problem easier to solve?

Because I have a hard time believing they can actually extract time increments and higher-level tasks from log data without a ton of pre/post-processing. But then the problem is just as much work as it was 5 years ago when you might have been using plain old BERT.

k8si··on Launch HN: PointOne (YC W24) – Automated time tracking for lawyers
Why? Do they not know where the data in their own system, that they built, is being sent?
k8si··on Speech and Language Processing (3rd ed. draft)
I suggest going through the exercise of seeing whether this is true quantitatively. Get a business-relevant NER dataset together (not CoNLL, preferably something that your boss or customers would care about), run it against Mistral/etc, look at the P/R/F1 scores, and ask "does this solve the problem that I want to solve with NER". If the answer is 'yes', and you could do all those things without reading the book or other NLP educational sources, then yeah you're right, job's finished.
k8si··on Christopher Nolan calls out Silicon Valley leaders at ‘Oppenheimer’ screening
Why do people pretend that alignment of AI is the important problem to solve, rather than alignment of the companies that run AI products with the wellbeing of humanity?
k8si··on Ask HN: How to deal with 0.1X programmer colleagues?
Do something more ambitious that is bigger and more impactful than closing JIRA tickets.
k8si··on FDA approves first nonprescription daily oral contraceptive
You are a teenager who needs oral contraceptives because you are sexually active. You don't want your parents to find out. Since you're a teenager, you have a few constraints:

- you have no car, how do you get to your doctor's appointment without asking parents for a ride?

- you are a minor, do you have any guarantee that your doctor won't tell your parents? You can't risk them finding out, they are very conservative

- you may not have ever made a doctor appointment for yourself before, maybe don't have access to insurance information etc

Planned Parenthood provides BCPs at a price you can afford with your teenager job (also guarantees privacy) but the closest one is hours away...

What do you do?

k8si··on Eating microwave popcorn increases the level of PFAS in body (2022)
Certain brands (e.g. SkinnyPop) advertise their bags as "chemical-free" (SkinnyPop claims their's is free of PFOAS). Can anyone help me understand/verify these kinds of claims?
k8si··on Berkshire Hathaway sells entire stake in TSMC
Does anyone know of a good piece of writing about what has made TSMC so successful, what makes their management so good, etc.? Seems like an operational exemplar I'd like to learn more about.
k8si··on Show HN: I've built a spectrogram analyzer web app
What we really need is PraaS (Praat as a Service). Praat Cloud Edition. Etc.
k8si··on Why is GPT-3 15.77x more expensive for certain languages?
Communication rates are very similar across languages: https://www.science.org/doi/10.1126/sciadv.aaw2594

See also (great read): https://pubmed.ncbi.nlm.nih.gov/31006626/

wrt your Spanish example: grammatical gender adds information redundancy to make it easier to process spoken language (e.g. helps with reference resolution). This redundancy enables Spanish speakers to speak at a relatively fast rate without incurring perception errors. English has fewer words but a slower speech rate. It's an optimization problem.

The speech rate issue isn't as obvious if you're only looking at text, but I'd argue/speculate that lossless speech as a language evolutionary constraint has implications for learnability.

tl;dr there is no communication tax, languages are basically equivalent wrt to information rate, they just solved the optimization problem of compactness vs speech rate differently

k8si··on Why is GPT-3 15.77x more expensive for certain languages?
"word" isn't a useful concept in a lot of languages. Words are obvious in English because English is analytic: https://en.wikipedia.org/wiki/Analytic_language

But there are tons of languages (not just CJK languages) that use either compounding or combos of root + prefix/suffix/infix to express what would be multiple words in English. E.g. German 'Schadenfreude'. Its actually way more useful to tokenize this as separate parts because e.g. 'Freude' might be part of a lot of other "words" as well. So you can share that token across a lot of words, thereby keeping the vocab compact.

k8si··on Why is GPT-3 15.77x more expensive for certain languages?
I don't know what you mean by compiler terms but basically, worse tokenizer = worse LM performance. This is because worse tokenizer means more tokens per sentence so it takes more FLOPs to train on each sentence, on average. So given a fixed training budget, English essentially gets more "learning per token" than other languages.
k8si··on Amazon to lay off 9,000 more workers after earlier cuts
Companies have been hand-wringing about the tech labor shortage for the last 10 years. People went to school and got degrees in a job sector they thought would be pretty safe. Supply/demand.
k8si··on Generative AI is overrated, long live old-school AI
For GPT4: "Pricing is $0.03 per 1,000 “prompt” tokens (about 750 words) and $0.06 per 1,000 “completion” tokens (again, about 750 words)."

Meanwhile, there are off-shelf models that you can train very efficiently, on relevant data, privately, and you can run these on your own infrastructure.

Yes, GPT4 is probably great at all the benchmark tasks, but models have been great at all the open benchmark tasks for a long time. That's why they have to keep making harder tasks.

Depending on what you actually want to do with LMs, GPT4 might lose to a BERTish model in a cost-benefit analysis--especially given that (in my experience), the hard part of ML is still getting data/QA/infrastructure aligned with whatever it is you want to do with the ML. (At least at larger companies, maybe it's different at startups.)

k8si··on The future of work isn't just remote, it's part-time
Seems like accepting lots of part time work would be a great way help employers pay us less and take away benefits/working hours flexibility. I don't wanna be a gig worker. I want a salary, benefits, and a 4 day work week.
k8si··on Study finds link between 'forever chemicals' in cookware and liver cancer
How do people feel about the GreenPan products?
k8si··on The semantic web is dead – Long live the semantic web
Very hard to make a business case because for the reasons you mentioned + the costs are very front-loaded because ontologies are so damn hard to build, even for very well-contained problems. Without a clear payoff, why bother
k8si··on Twitter says Musk’s spam analysis used tool that called his own account a bot
Incredibly irritating how much of everyone's time Musk has wasted on this
k8si··on Twitter confirms zero-day used to expose data of 5.4M accounts
What should Twitter do to fix the problem?
k8si··on Librarian's Letter to Google Security
Not for people who are homeless or don't have an ID for whatever reason, and need access to social services.
