antegamisou··on Meta-analysis: On average undergraduate students intelligence is merely average
The final, formatted version of the article will be published soon.

Haha, smart way to gain traction even if the final paper turns out to tell a completely different story from the abstract..

antegamisou··on Kalman filter from the ground up
Apple uses EKF (Extended Kalman Filters) for the iPhone's GNSS system:

I'm 100% sure there's some form of EKF on some loop on AirTags too.

antegamisou··on Kalman filter from the ground up
Hoped someone here would come out and say this.

It's only supposed to be somewhat intuitive for those who already possess some intermediate level college math background.

And no, rejecting the notion that not every advanced topic is supposed to be accurately ELI5-ed with a cringy Redditesque tone, means neither there's any gatekeeping taking place nor there's lack of understanding from the potential explainer's side.

Did your highschool physics not have this?

Gotta love that USA's 'A'P classes' entire curriculum are Chapter 1, p.1 everywhere else.

Hey at least the first result isn't some StackOverflow overlord schooling you on why you should never use endswith, right? /ₛ

Evolutionary Computation has, surprisingly, been successfully integrated in many engineering (not software!) problems such as antenna design, aerodynamics and whatever else has to do with shape optimization.

Similar experience here. Nostalgia from XP days is so strong I forget the monstrosity the OS became from every release from 8.1 onwards.
antegamisou··on So you want to learn physics (2021)
Halliday & Resnick Fundamentals of Physics is what we used in AP as well as in freshman year at college. Covers most sections one needs to be familiar with to be physics literate (solid/fluid mechanics, waves, thermo, electromagnetism, optics, relativity).
antegamisou··on Finland provides housing and counseling to the homeless (2020)
There is no population that actively rejects any form of housing (cardboard boxes excluded) and if there is, they definitely aren't moving to large urban areas en masse.

And even if it's the case that they were formerly sheltered but 'decided' to be homeless again, it's probably the shelter provider that didn't do a great job at accommodating them.

In any case, cultural opposition to housing is a pretty weak argument to make in order to express despair where your valuable taxpayer money goes to.

antegamisou··on Finland provides housing and counseling to the homeless (2020)
> (1) People are comfortable on the streets, they enjoy the freedom, or they are at least accustomed to it, and paying rent/bills seems anathema to them.

This has to be the most peak late stage capitalism shit I've ever read here. It's not a terrible idea to keep a few things to oneself I guess...

antegamisou··on Career advice for young system programmers
The author likes to point out how developer career online advice, blogs, rants etc. aren't applicable to low level programming roles, with a patronising tone but they're right nonetheless. Although embedded people will say the same about system guys, TCS researchers about all types of SWEs and so on.

However they seem to be falling into the same pitfalls with the frontend rockstar programmer-influencers; omitting and even undermining the importance of formal computer science education.

Especially if we're talking about getting into non-web development/IT roles, it's quite a lofty goal to expect mastery in programming complex software without some structured curriculum that will help you obtain the fundamentals to do so. And no, Coursera unfortunately won't make the cut most of the time.

Get a degree in Comp. Sci/Comp. Eng or at least some STEM degree and then a Masters. I understand the US-centric view of tertiary education being a risk due to large capital investment but in the rest of the world where it's affordable/free, most would hesitate to hire self-taught developers, even in web development positions.

The degree may not be enough for systems programming competency and this is where advice in the article about open source contribution comes to play, but I'd say it's kind of necessary unless you're some bunniefoo type of brain or idk.

antegamisou··on 8 Ways Journalists Can Access Academic Research for Free
May be field dependent but unfortunately the most likely outcome is the authors never getting back to you.
antegamisou··on 8 Ways Journalists Can Access Academic Research for Free
Looks like it's covertly suggested in #5

    5. Install Browser Extensions

    Browser extensions can help you check the web for free versions of academic articles. 
    The Unpaywallbrowser extension gathers content from more than 50,000 journals and open-access repositories worldwide. 
    The Open Access Button searches “millions of articles” from sources that include “all of the aggregated repositories 
    in the world, hybrid articles, open access journals, and those on authors’ personal pages,” according to its website.

    If the Open Access Button does not find free versions of the articles you’re looking for, it will contact the authors and
    ask them to share their work by putting it into an open access repository.

antegamisou··on New acoustic attack steals data from keystrokes with 95% accuracy
This is hardly a new concept btw.

In 2005 ACM's CCS Zhuang, Zhou and Tygar presented Keyboard Acoustic Emanations Revisited [1]

    We examine the problem of keyboard acoustic emanations. We
    present a novel attack taking as input a 10-minute sound recording
    of a user typing English text using a keyboard, and then recovering 
    up to 96% of typed characters. There is no need for a labeled
    training recording. Moreover the recognizer bootstrapped this way
    can even recognize random text such as passwords: In our experiments, 
    90% of 5-character random passwords using only letters can
    be generated in fewer than 20 attempts by an adversary; 80% of 10-
    character passwords can be generated in fewer than 75 attempts.
    Our attack uses the statistical constraints of the underlying content, 
    English language, to reconstruct text from sound recordings
    without any labeled training data. The attack uses a combination
    of standard machine learning and speech recognition techniques,
    including cepstrum features, Hidden Markov Models, linear classification, 
    and feedback-based incremental learning
which builds up on Asonov & Agrawal's work [2] who came up with the idea the previous year (2004).

    We show that PC keyboards, notebook keyboards, telephone 
    and ATM pads are vulnerable to attacks based on
    differentiating the sound emanated by different keys. Our
    attack employs a neural network to recognize the key being 
    pressed. We also investigate why different keys produce
    different sounds and provide hints for the design of homophonic 
    keyboards that would be resistant to this type of attack.

antegamisou··on Ask HN: For advice: I'm a mathematician looking for a plan B outside of academia
> Having a math Ph.d does not cut it. It is mostly irrelevant actually.

Maybe this applies to the lower paying quant roles (Trader/Dev).

No chance of getting hired for a Quant Research position without grad school education though.

antegamisou··on A collection of quant riddles with answers
There's a reference to the classic Heard on the Street book but you should also check out Zhou's green book, which consists a guide on cracking the type of interview questions Google used back in the mid 2000s/early 2010s (how many ping pong balls can fit in an airplane), with much more demanding problems though:

antegamisou··on A non-mathematical introduction to Kalman filters for programmers
We're talking about a specific subset of people working in Computer Science.

No one right in their head would claim that knowledge of 'only' HS math is insufficient when it comes to having a successful career in Front-End, Back-End, Ops, Cloud etc and many other positions pertaining to web technologies. I have no idea what people in this sector do but I'd highly doubt advanced math knowledge would even benefit their career considering they are remaining there.

However the fact that there are people on this very platform saying that those who say Linear Algebra mastery is "gatekeeping" to people aspiring to become Machine Learning engineers demonstrates, at the very least, poor critical thinking on their part about the inefficiency of self - learning math only through 'pleasant' means such as:

    I will only watch this cool video with animations,laying on my bed, about this hard math concept instead of grabbing some paper and pencil and carefully study some high quality  textbook. I need to built intuition ASAP !!!
as well as showing that various different AI Bootcamp: Become an ML expert in only two weeks!! type of cashgrab scammers are sadly growing exp. in popularity.

This is your brain on LLMs!!!

Nice typo but 100% agree, and if you dare tell anyone some freshman college math is necessary to understand some moderate-advanced subject, you're "gatekeeping" knowledge.

Ouch. Compared to current ones, I'd unfortunately have to say yes.

Personally Windows 8 UI and after is the reason I'm never going to touch this specific OS again. In fact, I find it an even bigger hindrance than the monstrosity Windows Updates is.

I should’ve clarified I was referring to the old (2021) article at the OP when I was talking about the high quality.

The recent ones haven’t remained in the same pathway unfortunately.
