samuel··on Amazon sales of Deep Learning with Python are counterfeit
The fake copies look pretty legit to me. 100% I would have been tricked (I haven't already, I own an Aurelien Geron book).
samuel··on The Daily Wrong: AI-Generated Lies Every Day
Only the images are generated by AI. The prompts seem to be written by humans. Impressive still.

I was flabbergasted for a moment thinking everything was AI generated. Even a bit scared, honestly.

samuel··on Tech Companies Won't Say If They’ll Give Cops Abortion Data
WhatsApp is not like the others, since it's end to end encrypted. The protocol even provides deniability (although it may be hard to hold in court).
samuel··on The end of Roe will bring about a sea change in the encryption debate
Math enables encryption but by itself doesn't encrypt. Software does.
samuel··on The end of Roe will bring about a sea change in the encryption debate
Thanks god someone sees it as clearly as I do. The whole article is pure madness, it even states "Law enforcement is a scourge on Americans’ personal safety".

I'm sure law enforcement in the US has a lot of problems, but this is pure nonsense. I'm really concerned about what it's going on in the US because if an article like this makes into HN, it means the situations is as bad as it seems.

samuel··on Ask HN: Have you used SQLite as a primary database?
DuckDB is the OLAP equivalent of SQLite, as far as I know.
samuel··on The only thing we should be talking about is the climate crisis
Yes, making developing nations richer faster so they reach developed countries birth rates sooner.

Educating girls and empowering them on those countries also will make birth rates to decline faster.

samuel··on The only thing we should be talking about is the climate crisis
A state with nuclear weapons and ruled by an authoritarian tyrant without any counterbalances is waging a war while throwing threats to other nuclear weapon states.

This is happening in the part of the world where I live in.

Furthermore, the countries involved in this war are the biggest exporters of some crops and we could be facing global famines this very same year.

So, no.

samuel··on Word2Vec Explained. Explaining the Intuition of Word2Vec
For me the key point to understand what's going on(assumming I got it), is that the hidden layer "has" to produce similar representations for words that appear in the same contexts so the output layer can predict them.

The intuition behind doc2vec it's a bit harder to grasp. I understand the role of the "paragraph word": it provides context to the prediction so in "the ball hit the ---" in a basketball text the classifier would predict "rim" and in a football one "goalpost"(simplifying). But I still don't get why similar texts get similar latent representations.

samuel··on Singapore prime minister Lee Hsien Loong’s Sudoku solver (2018)
Different as in completely wrong.
samuel··on Singapore prime minister Lee Hsien Loong’s Sudoku solver (2018)
> I do not know the specific background of Mr Lee, but the thing I always tell myself is that you can teach programming to a microbiologist, but not microbiology to a programmer.

I don't know if microbiology is special in some sense, but I have witnessed several times during my career cases of programmers turned into domain experts(in Logistics for example).

Obviously you don't became an MD that way, if that was your point.

samuel··on Ask HN: Career change for elderly UK ex-convict?
Probably not what you want, but webdev skills are more marketable for freelancing, which seems your better chance of avoiding deep scrutiny.

Best of luck.

samuel··on English has been my pain for 15 years (2013)
I can totally relate. Reading lots of english makes very little to your listening skills.

I mostly "solved" it by listening lots and lots of podcasts, but I can still remember googling the word "ossom" which a podcast host repeated every two or three sentences. I was puzzled to discover that he was actually saying "awesome", a word I definitely knew and I was familiar with.

samuel··on Stop Making Students Use Eclipse (2020)
For solving the sieve of Eratosthenes youn need 0 dependencies, and Eclipse gets in the way all the time(I have seen it and it's painful to watch).
samuel··on Willingness to look stupid
I was too afraid to ask, honestly.

I have another one. Why don't he spend 5 minutes making the content readable? Add some margins, it's all what it takes.

samuel··on Running BGP in large-scale data centers
I remember a blog entry about a guy who took Amazon offline for some minutes and was fired, even while the change had beend aproved by several people.

I can't find it right now but that's the kind attitude you would expect from Amazon. I guess what FB is going to do.

samuel··on Why I Use Nim instead of Python for Data Processing
I did, I don't think the snarkiness was necessary.

My point, which apparently it wasn't evident enough, is that you can get the most of the benefits by doing nothing, just trying a different Python implementation, without the hassle of learning a niche language, as easy as it might be.

BTW, if you take into account compilation times the difference is even meager, and in all fairness the PyPy warmup period should have had to be discounted.

samuel··on Why I Use Nim instead of Python for Data Processing
For me the corollary of this post should be, try PyPy. You may get a 10x speedup for free.
samuel··on Structural pattern matching in Python 3.10
It is. But stablished idioms became obsolete, and the code that used them becames unidiomatic. And you have to learn them if you want to read other people's code.

Python doesn't need more features but better implementations, IMO.

Edit: Just remembered the Zen of Python, I don't think modern Python is following it.

...

Simple is better than complex.

...

Readability counts.

...

There should be one-- and preferably only one --obvious way to do it.

samuel··on Structural pattern matching in Python 3.10
Once my favorite language by far, Python is starting to became too cluttered. Very few of the additions to the language in the 3.x branch are worth it IMO.

I remember that in the early 00's people called it "executable pseudocode". I bet nobody would use now that expression for modern Python with decorators, comprehensions, walruses and the like.

samuel··on Show HN: 40k HN comments mentioning books, extracted using deep learning
This is amazing. Thank you!

Does it take into account negative reviews/comments? I have seen that Why we sleep is being recommended in the 6 months tab, but, while it was received with a lot of praise, it was soon critizised by others researchers in the field and I would expect that the HN crowd would have followed that trend.

samuel··on Show HN: 40k HN comments mentioning books, extracted using deep learning
REAMDE was crap, IMO, and I'm a Stephenson fan.

And the problem with Stephenson is that's rarely succint so a bad book from him turns into a huge loss of time.

samuel··on China prepares to test thorium-fuelled nuclear reactor
China has no voters, so they don't need to be worried about public opinion(for now).

Furthermore, the effects of air pollution are more evident there so it's easier to sell the tradeoff, IMO(I know almost nothing about China, TBH).

samuel··on The NSA's Backdoor in Dual EC
That's one of them, and the least interesting of both. I remember that the other one was way more concealed and involved a global variable or something like that and it didn't seemed that the code was doing what was actually doing.

There was an amazing blog entry which explained it, but can't find it right now.

Edit: I don't think this was the one I read, but it's similar. https://cryptologie.net/article/316/junipers-backdoor/

Basically, Dual EC was chained to another PRNG, so the output should have been robust to crypto vulnerabilities discovered in any of both. The thing is: the second one was never called, because the for's index(a global variable) was set to 32 inside a function call, so the loop never run.

samuel··on The Sunk Cost Fallacy
If I understand correctly the sunk cost fallacy your example lacks an objectively better alternative, like an opportunity related to one of your hobbies, unrelated to your studies, which could land you in a great job in some years. As you stated it, there's no doubt, staying in the PhD is the only rational choice.
samuel··on Ask HN: Technical Summer Reading List
I came here to recommend "Statistical Rethinking" but if you have read(and understood) the Gelman one, you can skip it completely...
samuel··on EE to reintroduce data roaming charges in Europe, following Brexit
Yet they didn't do it, aside from very minor exceptions.

And with good reason, trying to outbid each other doesn't make a great strategy to keep a Union.

I don't get why I'm downvited, btw.

samuel··on EE to reintroduce data roaming charges in Europe, following Brexit
But also a much higher vaccination rate. Probably a few thousands more of your compatriots would have died had you followed the EU vaccination program, don't forget that.
samuel··on TeXmacs 2.1
Thanks, I'll look into it. I enrolled in a Master' Degree after almost 20 years out of the University, and had to do some mathy reports. Forgotten most of my raw LaTeX skills and not interested on doing the investment again, went directly into LyX, which I remembered it was already nice in the 00's. It was OK.

But if I have the time(and the need), I'll try TeXmacs.

samuel··on TeXmacs 2.1
How does it compare to LyX?
