agucova··on American phone-tracking firm demo’d surveillance powers by spying on CIA and NSA
This should be on the frontpage.
agucova··on Ask HN: Do you use an optimization solver? Which one? Do you like it?
I've used Gurobi and Mosek and today I tend to use Gurobi whenever I can as a default.

I use JuMP to switch solvers to Mosek or an open source solver is something doesn't go as expected.

agucova··on The best engineering interview question I've ever gotten
While it took me under an hour, I still wonder whether my implementation would have passed an interview. I generalized do_add_delta to three operations (incr, decr, mult) and otherwise copied code paths and extended the binary protocol.
agucova··on Retype: A self-hosted and free alternative to gitbook
> “UNDER NO CIRCUMSTANCES MAY YOU USE THE SOFTWARE FOR AN APPLICATION THAT IS INTENDED FOR SOFTWARE OR APPLICATION DEVELOPMENT PURPOSES.”

Perhaps I'm just not getting the point of this statement, but isn't this really broad and ambiguous?

agucova··on The State of Fortran
This only speaks to the academic nature of Fortran, and there's nothing wrong about it.
agucova··on Ask HN: Which book can attract anyone towards your field of study?
Sapolski's book (Behave) and his Stanford classes on YouTube are just awesome.
agucova··on Fornjot – The world needs another CAD program
OpenSCAD is mentioned in the first article in the website, “The world needs another CAD program” [1]:

> The most popular Code-CAD application, as far as I can tell, is OpenSCAD. While programming your CAD models, like you would program software, provides a lot of flexibility, the feature set of OpenSCAD is otherwise very limited. This makes many CAD modeling tasks tedious.

> I want to use something more powerful, and that rules out OpenSCAD and a whole bunch of other less-known alternatives.

agucova··on Barcode Detection API
It's a heavily standardized, very recurrent problem that can take a lot of advantage of native code and platform-specific optimization, so it's really an ideal target for a Web API.
agucova··on Barcode Detection API
MDN is meant to be a somewhat universal resource for web development. I've even seen official Google web dev resources pointing to MDN.
agucova··on Using email wrong
The controversial part may be a reference to Basecamp's last year's ban on “societal and political discussions” at work, which was apparently motivated by the desire to end internal discussions about the company itself [1].

agucova··on Show HN: I made a privacy-first minimalist Backblaze
If this would allow me to check my files in a simple web UI (no need for collaboration or anything), and create share links for low-volume downloads I could just leave Google Drive permanently.
agucova··on Advice on accessing BBC News
Non-encrypted email in transit is a concern, but AFAIK most users should already be protected nowadays. (Google estimates [1] put it at around 9/10, tho probably not representative of Russia)

A bigger concern might be Russian-monitored email servers, especially given that around 70% of the market share is occupied by Russian providers [2], and email isn't considered personal data in Russia [3].

Update: as for transit, see adam-p's comment.

agucova··on Advice on accessing BBC News
Those sites aren't banned in the EU, this is pure misinformation.
agucova··on New York Times tech workers vote to certify union
It is, but I guess it's a good sign of neutrality that they did report on this.
agucova··on I love you, Hacker News, but you’re toxic
I think you may have demonstrated his point.
agucova··on I love you, Hacker News, but you’re toxic
Sure, but he is not arguing for toxic kindness.
agucova··on I love you, Hacker News, but you’re toxic
How does that change the toxicity he has observed? It's still as present, that doesn't do anything to change his argument.
agucova··on I love you, Hacker News, but you’re toxic
You can be skeptic and offer constructive critique while being kind. It's more about the attitude than the content of the message.
agucova··on U.S. is considering a radical rethinking of the dollar for today's digital world
This seems interesting, but I doubt this would be a vulnerability of any properly redundant digital coin.
agucova··on Ask HN: Software you hate but can't replace?
Huh, always wondered why my LG TV never got ads and just remembered my entire house is under NextDNS's blocking.
agucova··on Poll: Where do you live?
Now I really want to meet those other two Chileans.
agucova··on Huginn: System for building agents that perform automated tasks online
An alternative to this (more similar to node red, actually) is n8n [1], which is pretty cool, but as others have said here, I never found a good application for this.

agucova··on Mars rover detects carbon signature that may hint at past life source
Is anyone else having problem accessing the paper? The link on Science isn't working, and the DOI I managed to find in the rest of the coverage doesn't seem to exist. I can't find the paper anywhere.
agucova··on Statistical Rethinking (2022 Edition)
I think the classes opt for starting with a simple mental model students can adopt, which is gradually replaced with a more robust and nuanced mental model.

In this case he wasn't talking just about frequentist methods tho, it's also talking about doing statistics without first doing science (and formulating a causal model).

I would be wary of jumping to conclusions from that introduction alone if you haven't seen the rest of the course or the book.

agucova··on Statistical Rethinking (2022 Edition)
I guess it really depends on your discipline, but Bayesian methods have become more and more popular in a lot of academic communities, being published alongside papers using frequentist methods, so I wouldn't say it's hegemonic anymore.
agucova··on Statistical Rethinking (2022 Edition)
This is taking the quote completely out of context, it's not the data itself that conveys useful information, it's the data combined with a causal model!
agucova··on Statistical Rethinking (2022 Edition)
I'm following the course using Julia/Turing.jl and it's simply awesome.

Richard McElreath clearly has a talent for teaching, and both the lectures and his book also give a very insightful discussion on the philosophy of science and common pitfalls of common statistical methods.

Last semester I took my first classical Probability and Statistics course at my uni, and this course has been positively refreshing in comparison.

agucova··on Statistical Rethinking (2022 Edition)
You'll probably need some basic notions of statistical distributions and data analysis; I recommend reading the first chapter of the book or the first lecture and seeing whether you're missing anything important.
agucova··on Statistical Rethinking (2022 Edition)
Even if you don't like R, your can do the entire course with Julia/Turing, Julia/Stan or Python, the course github's page has a list of “code translations” for all the examples.
agucova··on Stories Are Coming to Signal
If this gets more people to use safer, better messaging apps and/or fund Signal, I'm all in.

There's no place for purism, I just hope they add a way to disable stories for unwilling users.
