jpamata··on Ask HN: Why don't LLMs replace bosses instead of engineers?
Strategy is far from the bulk of their work

Most of their job is about people, leverage, and execution. It's not a sit and think job, it's mostly 1:1s and coalition-building

Theyre also utilizing LLMs to augment themselves. And are getting more data, from off-record convos to reports from trusted smart colleagues who used an LLM to refine their intel

jpamata··on Trump wins presidency for second time
Could be, or the Ukraine war, the pandemic, or some other policy

It's nonfalsifiable. People will settle on the simplest observation:

it happened under Biden

jpamata··on How I write code using Cursor
yes, the quote is what I'm referring to, directing the AI is part of it, people use these to quickly brainstorm and refine ideas. I'd be more charitable and wouldn't hastily assume it was some skill issue, especially them being a principal engineer
jpamata··on How I write code using Cursor
they said 90% of it was spent on ideation and exploration

they didnt specifically mean they built a wordle clone, just a game like it. if they wanted just a wordle clone, they wouldve gotten one within a few minutes of using codegen tools.

jpamata··on Starship Flight 5: Launch and booster catch [video]
Is there any source for first-hand specifics of what she does?

I used to argue in reddit (same username as my HN) basically calling Musk a fraud and Gwynne Shotwell being all the brains 6 years ago, but I've since changed my position after seeing engineers in spaceX give props to Musk at podcasts, twitter, and various interviews.

jpamata··on Ask HN: What is the best way to author blogs in 2024?
Jekyll, hosted on github pages is what I use

Currently using a theme from here https://jekyll-themes.com/free

When I'm travelling I could just edit the markdown/upload photos on the phone browser

jpamata··on Ask HN: What are the most underrated skills in tech?
CP just teaches some familiarity with DSA/algorithms, and there's much more to perf than DSA. Even assessing algorithmic performance requires real benchmarks and profiling, while the complexity analysis people do in CP disregards other factors like hardware, architecture, format, and other abstractions. Squeezing perf via DSA is much more easier/straightforward, people don't need to grind CP to learn that
jpamata··on Llama3 implemented from scratch
Author is probably young, that's how gen-z are these days, if they dont have autocorrect on, the whole text will be in lowercase.

Also it looks more casual and authentic, less LLM generated

jpamata··on Happy New Year HN!
Happy New Year hackers! Here's to the crazy ones
jpamata··on Charlie Munger has died
I guess lots of people find him interesting (see HN guidelines)

Charlie (and Buffett) are often recommended here for their mental models as their approach to investing and finance are very transferrable in startups/engineering. At the end of the day, large scale software engineering is mostly about managing risk, strategy, and corporate finance/value. Often, Poor Charlie's Almanack is recommended by my top Staff+ colleagues.

jpamata··on Ask HN: Any interesting books you have read lately?
This month I'm reading The Way of Kings by Brandon Sanderson

Used to think fiction was a waste of time a month ago. Not anymore.

jpamata··on Ask HN: Is anyone else noticing degradation of comment quality on HN?
I wouldnt say so. I think it's the same HN. Although when it gets political, I've noticed that the discourse does degrade a bit faster than it used to be for such topics, for there's a bigger pool of users who'll get provoked by the opinion
jpamata··on Introduction to Algorithms: A Creative Approach by Udi Manber [pdf]
A book that has a similar style to this one (teaching algorithm design) and my personal favourite is Algorithmic Problem Solving by Roland Backhouse.

It just teaches algorithmic problem solving via math, but unlike mathy algorithmic books like CLRS, you only need algebra for this one.

I like how the book, IIRC, starts with invariants, providing the reader the foundational skill needed to notice underlying patterns and to decompose problems.

jpamata··on Bombings of Hiroshima and Nagasaki (2014)
That's why I said karmic justice.

I think it's a close book. The book details the decision process from both sides. Japan's plans to continue the war. The way the high command coped with the first atomic bomb, etc. It does not sway you into thinking any side was justified, but it expands one's perspective to help you understand the other's side.

jpamata··on Bombings of Hiroshima and Nagasaki (2014)
I was born in Southeast Asia, lived in China for a while, everyone I've met views it as some kind of karmic justice. It's the idea you get from school (we were living peacefully, then we got attacked and they did all these brutal crimes) and from our grandparents.

I've only seen the contrarian opinion coming from westerners. Perhaps because there's barely any media from Hollywood about the pacific theater, and if there was (eg. HBO's The Pacific), it does not show the horrors of it.

If one is more interested in an objective take on history, especially those using the argument that the Japanese were already "defeated" before the bombs came, then the book Downfall by Richard B Frank is a good book to start with for those who hold a firm anti-nuke stance.

jpamata··on Tell HN: CS departments should make Programming Languages a compulsory course
Making them compulsory would be good, but replacing the "intro" courses with a paradigm-survey course would probably be too much for students to handle.

Students would also likely not be technically mature enough to be able to appreciate these early in their journey. I certainly didnt when I worked through SICP in my late freshman/early sophomore year, eventually I ended up forgetting everything about it.

I like the PLAI lectures as the prof (Shriram) was able to relate the concepts to those in the industry and various languages like haskell, as well as made it practical by discussing program design -- perhaps HtDP was also a prerequisite?

jpamata··on Ask HN: Book Recommendation on Database Internals
"How Query Engines Work" by Andy Grove, you build one in Kotlin: https://leanpub.com/how-query-engines-work

The author also made it available for free at https://howqueryengineswork.com/00-introduction.html

On implementation, my favourite is "Database Design and Implementation" by Ed Sciore, you write a relational DB in Java, including the parser.

jpamata··on Linda Yaccarino is the new CEO of Twitter
With rockets, he is deeply involved in the area and his proficiency have been confirmed by top engineers, a few quotes from them here:

https://old.reddit.com/r/SpaceXLounge/comments/k1e0ta/eviden...

I'm not sure about Elon's proficiency with software, but based on his comments on twitter I'd lean on him being out of touch there. He does seem to be knowledgeable on the AI/DL side though, see Andrej Karpathy's comment:

jpamata··on SpaceX Starship rocket explodes minutes after launch from Texas
This post quotes top SpaceX engineers like Tom Mueller, Kevin Watson, Garrett Reisman, Josh Boehm, and others like John Carmack about Musk's involvement in engineering:

jpamata··on Ask HN: What are some of the best university courses available online for free?
A series of distributed systems courses from UIUC at coursera where you learn about systems design, distributed algorithms, and has you build projects like a distributed DB, implementing algorithms like gossip protocols, etc. in C++:

jpamata··on Last Flight Out
Always loved reading about adventures in Antarctica. It feels like the closest thing we can get to going to an exoplanet.
jpamata··on Play Counter Strike 1.6, with full multiplayer, in the browser
Nostalgia. CS 1.2 with our family's bad windows 98 PC in the early-2000s was how I got into computers as an 8 year old kid. It was so laggy on our low end PC, it took about 5 seconds to shoot. It was like watching a slideshow presentation with delayed sound. It was until I discovered the internet and browsing around forums, that I found a solution to hack around it. Later I started making bots and mods, getting my first exposure to programming. But that exploration stopped when I discovered a very grindish online game that became massively popular in the 2000s called Runescape.
jpamata··on Ask HN: What's Going to Replace Twitter?
None. The era of 1-1 social media is gone, it's now 1-many.

Especially for the younger generations, they dont tend to stay and invest their time building profiles in just one or two social media, they use it all. There's no such dedicated efforts to "move." Only what is popular and trendy.

jpamata··on Ask HN: What are the foundational texts for learning about AI/ML/NN?
ISLR for foundation and passing interviews. It also has lectures in youtube, just type ISLR lectures.
jpamata··on George Hotz: Resigned from Twitter Today
Unless geohot ticked the record option during his twitter space, it wont have the replay button. Quite a shame, it was the most candid tech talk I've seen Musk was in, and Hotz was challenging him his points about twitter engineering and policies.

I saw someone posted a screenrecord on youtube[0], but the whole space lasted 2 hours, with Elon being there for an hour.

jpamata··on George Hotz: Resigned from Twitter Today
Looks like you're right. He kept pushing for a dedicated refactoring effort throughout his live Q&A with Musk here, pointing out several services:

https://twitter.com/realGeorgeHotz/status/160542468694643097...

He also talks about how some changes he made, such as removing the annoying login/signup popup when viewing twitter posts, were reverted

jpamata··on The Twitter Advertiser Exodus
Probably just that he doesnt want to waste time on it. He's been shown to be a powerhouse problem solver. Since we're posting tweets:

jpamata··on Tell HN: Reddit does not allow comments post via old.reddit.com
Not me. Logging in and writing child-comments (top level comments seem to work for both old and new) does not work for me when I'm using old reddit. But if I visit new reddit, the child comments appear and it also says that I am logged in. Oh well, it's a good time to leave reddit anyway
jpamata··on Ask HN: Why does HN not have a dark mode?
I hope they implement it as a user option that you can turn on/off anytime. Dark mode hurts my eyes. Every time I read large blocks of white text over a dark background, I usually end up having a double vision of the text and later a headache. I find warm light to be the best
jpamata··on U.S. surgeons transplant pig heart into human patient
Perhaps it plays a part on conditioning folks through generations on what is viewed as livestock. Dogs for a long time are not, except perhaps in China, which has only started looking into reclassifying dogs from "livestock" to "pets"

https://www.reuters.com/article/us-health-coronavirus-china-...

>even 1% of the anger is because the consumer has wasted resources on their food

Mao Zedong used that reasoning during China's cultural revolution for banning dog ownership
