kaiwenwang··on Brazil's government-run payments system has become dominant
Thanks for your insights. I had previously interviewed with some firms in the PwC KPMG Deloitte type of category, though the work and pay don't seem to be completely worth it based on what I've read.

Hello, the things you're talking about (previous comments, not just this) are interesting career-wise. If I studied Computer Science (long-term I do not see myself programming forever) and only have internships related in that area, how would you recommend getting into this field?

Isotretinoin is poison, here's my article about it: https://www.kaiwenwang.me/writing/effects-and-detoxification...

In some parts of the internet, Vitamin A is theorized to not be a vitamin but a poison.

Auto-immunity is likely related to biofilms in the intestines and plant defense chemicals such as lectins in combination with leaky gut.

Try looking @ cabbage juice for your Crohn's. There are YT videos about it.

Hijacking this thread to post some of my blog articles on nutrition/health. It's a topic I'm deeply concerned about.

I frequently run into young people with thin hair, girls with endometriosis, and a bunch of stuff people should not be having at this age.

I'd like to think my perception is insightful or at least novel on a variety of topics: exercise, pufas, vitamin A, indicators of health, plants don't want to be eaten, national food systems, rabbit teeth, glasses, and foldy ears.

kaiwenwang··on Re: Do people IRL know you have a blog?
A website is a Presentation of Self extended to artwork and 2D media.

What is a Presentation of Self? It comes the book The Presentation of Self in Everyday Life by Erving Goffman.

The two primary senses of humans are sight and vision. If you take the time to write down and enumerate the ways by which people understand the internal state of others, you realize that a computer simply communicates impressions of people over long distances, some of which have limited correspondence with who a person really is. Photos could be fake. Videos could be scripted and a certain impression. You don't really see someone for who they are except in real life, talking to them for a duration.

Most people talk to or avoid certain people internally based on how they act and what they say. But once you realize the structure of communication, you feel like a robot talking to others. What was implicit becomes explicit.

So yes, a website matters, if the increasing trends for humans and human ability are greater knowledge consumption, production, network communication over locality, and so on. It reveals your internal perception, taste, intelligence, and processing of information, by which people use to judge you and ask how relation to you improves the group fitness.

Having a website selects for intellectualism. Social media is also a presentation. The question could be rephrased: Do people know you have a TikTok or Instagram?

People such as his wife and digital people have increasingly different lifestyles and diverge. Had the author made his way to a metropole or more major place, it's likely having a personal brand would've mattered more.

kaiwenwang··on Perplexity is a bullshit machine
I see that they have bad design sense which I think generalizes to bad product sense and bad business sense.
kaiwenwang··on Perplexity is a bullshit machine
Perplexity probably isn't a good company for the reason that they have bad design sense and product.

If you go on their main blog such as (https://www.perplexity.ai/hub/blog/perplexity-raises-series-...), the monospace choice of font (not that it's monospace, just that from a design sense it doesn't seem right), the excessively large border, and the container being unaligned with the content/image/frontmatter all reveal this.

Would short Perplexity if I could. Bullish on Exa and Globe Explorer.

kaiwenwang··on Show HN: We built PriceLevel to find out what companies pay for SaaS
Reminds me of machowski's article on order books.

By making these things public, I think it'll decrease the variance in costs in the space. If it was public knowledge how similar SaaS are priced, people would always go for the cheaper option (this assumes identical features, which is not the case).

I guess in the end, pricing is determined by costs (materials, labor, rents) for a floor and then profits (which might as well be a random number).

kaiwenwang··on Universities Have a Computer Science Problem
Didn't know that about the DoD and DoE, good to know. What was your experience and your sister's experience (and at what places) if you don't mind me asking?
kaiwenwang··on Universities Have a Computer Science Problem
That's just the personal term I use to describe it, but I'd say it's a mix of lack of life experience, lack of expectations from the school, personal attitudes, lack of seriousness, lecture-hall style teaching and too many students, and low standards.

Examples:

- vandalizing all signs with the letter 't' around the school because the school has a reputation for "stealing a giant T" from a building, but all the students are too busy with career stuff to do anything like that

- saying "I want a job that pays me the most money"

- walking out in the middle of class after an attendance quiz

- administrative staff sending out emails with numerous typos

- lack of serious thought into important topics

I think American college students tend to be less mature than European ones due to being stuck in a suburb for 18 years as well.

Some other thoughts:

I'm not sure exactly how the future of GT will fare being a public school. A large reason for the lead was how early the school established the College of Computing.

Will private schools end up a better place to study CS due to their smaller class sizes and less variance in the student population? I can't say for sure due to not personally knowing what studying at those private schools is like, but I think large lecture halls are ineffectual as a continued method of higher education.

Another phenomenon is the amount of international students who come to the USA and are so focused on the idea and prestige of working for "Big Tech." Then they get there and find out how expensive the rent is, how expensive college was, and they spent all their time doing leetcode (which actually has some interesting fundamentals if you get really into it, it's not my thing personally though) and now graduate and think: now what?

Note: current GT student, going to comment on some thoughts on this article:

- Siloization of industries is a problem in general because it causes people to think dogmatically. Isbell makes a fair point, and it's more of a societal problem than a computing specific problem.

My intuition is that if medical school students memorize Anki decks, they're going to be good at pattern matching but not seeing the big picture and why things happen. People react poorly to being challenged, responding with either aggression or avoidance. Rarely do they ask themselves why something is the case.

Business people might know how to increase revenue but not understand what money is, how it is created and destroyed, and how it affects people's incentives.

- I'm not sure the computing ethos is taught particularly well in schools. For example, the Unix Philosophy for writing command line tools or GNU's free software. In my view, colleges should be an fast feedback learning environment with significant input from teachers, fundamental readings, and exposure to new things to point people in the right direction.

- Philosophy, math, and CS are a strong combination that go well together. I'm not surprised the author found himself at home in it.

- I don't worry that people get into CS and care only about machines. I worry that people are getting into CS only for the money, leading to the enshittification of everything. The problem is the moral values of society as a whole.

Fundamentally, Georgia Tech as a school strikes me as an industrial research/engineering powerhouse funded by federal grants, a major workforce contributor to F500 companies, and at its core a public school with the attitude and values students at public schools often have such as anti-intellectualism, which is promoted and visible in the administration and can be seen in how Georgia Tech changed its logo from a more academic, serious logo to an unserious logo. But this is a growing problem at universities everywhere across the US. Housing shortages, university degree oversupply, and so on.

The weakness in its CS curriculum is actually its threads, causing a lack of breadth. By focusing on a thread such as "People/Media," they can pick classes that don't even touch fundamental aspects of computing such as databases, networking, compilers, programming languages, and so on. Apparently CS is switching to a direct admit method to stop the 500-600 person classes I've had for almost the entirety of college.

I did have classes that focused on interesting topics such as law, differential privacy, cross-border data flows, philosophy and cognition, and so on. Particular classes I enjoyed were taught by teachers such as Galil, Swire, and Verma, where I felt the class content was serious, but this might also mirror my changing tastes in how education should be done as I get older. The harder and more serious the content and reading in a class is, the easier it actually is.

And there's also a big maturity and understanding change that happens as well, which I don't really think is changeable.

kaiwenwang··on Interesting programming articles I've saved
It's a bit hard to open in the Zotero sidebar, but most of the categories are under "Technical." Articles are mainly for early career people but are not mind-numbingly basic.

There was a company called Quaise in this field I read about in The Engine's portfolio, though I don't know enough about this subject matter to make much of a comment.
kaiwenwang··on Indian IT consultancies struggle against technological obsolescence
Off-topic from the thread, but was the sample size of GT students you've interacted only one, or greater? My intuition on well known public universities has been that they accept all the talented people at the cost of letting some who would struggle with the material while private universities accept only talented people at the cost of missing some people who would thrive.
