pkoird··on Quantum Mechanics, Concise Book
Nice effort. As far as textbooks for QM, Electrodynamics, and any sufficiently complex field of study goes, I always feel that these have been written using abstractions that people have developed much later retroactively. I understand the advantages: it makes the entire content concise, structured, and basically straightforward. However, what I crave is a technical book that is based upon the history of the subject. Something that doesn't start immediately with Hilbert spaces but starts off by talking about why Max Plank did what he did, how did Einstein improve upon it, what mistakes were made, what misguided hypothesis were later corrected in what manner, how were different things then unified... you get the point. I think this narrative based approach would motivate me much better than something that's condensed and distilled.
pkoird··on Spending too much time at airports
I cannot relate to your experience at least in US. I did a lot of flying this summer and have been flying both nationally and internationally over the years but outside the occasional delays due to weather, my experience has been quite pleasant. Even when traveling with luggage, I can generally check them in right outside the airport where I'm dropped off by Uber. Security checks have been straightforward with just the right amount of annoyance in the mix and mobile apps mean that any last minute changes to gates are well communicated in advance. I have found it all really streamlined to be honest.
pkoird··on Manim: Animation engine for explanatory math videos
Curious to see how it'll combine with a RAG on its documentation.
pkoird··on Manim: Animation engine for explanatory math videos
I used Manim for one of my class presentations, absolutely a delight to use and as expected many people recognized the style and overall the presentation was well received. Incredibly, I had the opportunity to meet Grant as well a few years back. I told him I have used Manim and he was genuinely excited. Such a cool person with so much contribution to human knowledge and understanding.
pkoird··on Maru OS – Use your phone as your PC
One of the things I love about my Samsung device is precisely this feature, i.e. DeX
pkoird··on The natural diamond industry is getting rocked. Thank the lab-grown variety
If the chemical composition is the same, yes.
pkoird··on Nobody knows how to build with AI yet
Potentially. But also remember what they say about self-driving cars, that it'd make fewer and fewer mistakes than a real driver.
pkoird··on A New Geometry for Einstein's Theory of Relativity
I can't simply help but think that optimal transport is intricately linked to the principle of least action (and as we know POLA is everywhere in nature). At the end, natural interactions seem to be one big optimization problem.
pkoird··on 'Positive review only': Researchers hide AI prompts in papers
Honestly don't understand why they have the prompt injection in arxiv of all places. One would imagine that a researcher aiming to leverage AI based reviews would only modify their private submissions.
pkoird··on Sendkeys: Command line tool for automating keystrokes and mouse events on macOS
Wonder how this compares to Autohotkey on Windows.
pkoird··on The First Hallucination-Free LLM
Cheeky. But they are wrong. In the screenshot itself, the model outputs "I'm just a human", which is to say it's factually incorrect. Which is to say, it's hallucinating.
pkoird··on Modelling API rate limits as diophantine inequalities
If they do not know about it already, the OP would benefit from knowing more about Linear Programming and Mixed Integer Linear Programming. Many optimization problems can be naturally modeled into LPs or MILPs and there are POWERFUL solvers with decades of theory and optimization behind them already developed to solve them.
pkoird··on AI fakes duel over impeachment of Vice-President in Phillipines
Good luck telling that to aging grandparents and people in third world countries who are just getting acquaintanted with the internet.
pkoird··on AbsenceBench: Language models can't tell what's missing
So LLMs are poor at string diff, it seems. Tangentially, is there any source (a github repo or otherwise) that documents findings like these a la what LLMs are good at and what they aren't good at?
pkoird··on The Emperor's New LLM
If the model is designed to agree, ask it why something is good, it'll come up with good points. Then ask why it's bad, it'll come up with bad points.

Finally, make a decision based on good and bad points?

pkoird··on Show HN: AutoThink – Boosts local LLM performance with adaptive reasoning
Back to TF IDF we go.
pkoird··on Trying to teach in the age of the AI homework machine
So they bomb their test. And? Isn't that the entire point of an exam? If you fail, you fail and presumably have to re-learn the contents.
pkoird··on A Critical Examination of Prayers
Well sometimes it just helps to verbalize all the suffering you are going through, in that aspect I don't doubt prayer has a therapy like effect. However, even if I were to believe in God, it feels superficial to ask him for material goods. The Hindu philosophy is particularly enlightening here as it says (something along these lines): "If you ask God, you'll get what you want. If you don't, you'll get what you need."
pkoird··on The History and Legacy of Visual Basic
Growing up in a third world country with no formal CS classes, I will never forget the wonder and awe I felt when I coded a simple calculator after self-teaching myself VB6 from a book I stumbled upon. The simplicity of drag and drop and the fluidity with which it simply worked has remained unmatched. I tried going back into App development time and again but these new container based paradigm just never clicked for me.
pkoird··on Using tests as a debugging tool for logic errors
Closely related are in-code assertions. I remember when I used to liberally use asserts inside a code (and you could disable them for production) to check pre-conditions, post-conditions, or any invariants. Nowadays, I don't think the pattern is recommended anymore, at least in certain popular languages.
pkoird··on Zuckerberg's Grand Vision: Most of Your Friends Will Be AI
A *rich one. Who knows if he's happy or not.
pkoird··on Zuckerberg's Grand Vision: Most of Your Friends Will Be AI
> “I think people are going to want a system that knows them well and that kind of understands them in the way that their feed algorithms do,”

My god, he thinks people like their feed algorithm.

pkoird··on Show HN: My from-scratch OS kernel that runs DOOM
Really really love the name.
pkoird··on Quick Primer on MCP Using Ollama and LangChain
What, according to you, are some alternatives that exist or are in development that fill these gaps?
pkoird··on 23andMe Files for Bankruptcy, as CEO Anne Wojcicki Resigns
Pets? People are crazy about the genetic makeup (and possible diseases) of their pets.
pkoird··on Richard Feynman's blackboard at the time of his death (1988)
It was dictated by Feynman. Parts of his original interview are still available as stated in my comment above. And as far as embllishment goes, I'm pretty sure all autobiographies suffer this fate.
pkoird··on But good sir, what is electricity?
Just to clarify, the high speed at which electrons generally move around in metal is called "Fermi velocity". Like you said, since it's random, on average it cancels out to 0. When applying an electric field, the electrons achieve a non-zero average velocity which is called the "drift velocity".
pkoird··on Richard Feynman's blackboard at the time of his death (1988)
I'm sorry but didn't we already establish that most of his famous books are the edited contents of his recordings with some of those audios available to download as well? Does a person have to actually sit down and write it out and dictations don't count?
pkoird··on Richard Feynman's blackboard at the time of his death (1988)
Many people write books on interesting subjects posthumously (biographies come to mind). I believe it would be up to the descendants of Feynman to sue if due legal etiquettes were not maintained. Having said that, all famous Feynman books like the Feynman lectures, Surely You're Joking Mr. Feynman, Please of finding things out, etc are edited pieces of Feynman's recorded audio, no doubt about that.

Honestly, my problem with the video in question is that its tone unjustly attempts to denigrate Feynman (starting with the clickbaity title itself, a sham legacy? really?) by trying to frame the narrative that his supposed works were not his to begin with. The comments in that video validate this sentiment to the point that people joke about him not existing at all? If this is the central takeaway of the video then I'm honestly glad that I didn't waste precisious few hours of my life on such misleading content. Feel free to correct me though.

To me, Feynman is iconic because of the way he communicates. Of course, there is a disjunction between the man and his ideas and I'm not unwilling to believe that he had some flaws.

pkoird··on Richard Feynman's blackboard at the time of his death (1988)
Without having watched the videos, to say that people made content using his name and made money off of it without Feynman knowing is disingenuous. Ralph Leighton recorded the conversations as Feynman was struggling with cancer. There are even portions of those recordings out in the web [1]. Feynman was fully aware of the books because there was apparently a scandal where Murray Gell-mann threatened to sue Feynamn and Leighton because of some mischaracterization. Feynman was apparently hurt and issued a correction in the subsequent version of the book [2]. So it seems that he was FULLY AWARE and actively endorsed the book.
