If you are getting a PhD without a stipend (~3k usd/month) and even paying tuition on top of that, you are doing something egregiously wrong. The financial opportunity cost is very high though especially in CS.
I see online synchronous 1-2 hour exams as a mistaken result of the "let's emulate in-person teaching in a remote setting" mindset.
You don't succeed in remote teaching and learning by trying to make it as close as possible to the in-person setup. You have to treat it as an entirely different problem.
Consider the synchronous exam. It is a perfect method of grading in-person. It is hard to cheat and all people take the same test in the same place. It is as fair as it can get.
In an online setting however, people can face all sort of troubles in a few hour window in their home. Your internet might stop working, neighbor might be making too much noise etc. Everyone takes the exam in a different setting and it is as unequal as it can get. It is also practically impossible to prevent cheating.
I always appreciate when someone leaves the well-defined path and does something different, such as you self-studying Math and getting enrolled in a Masters program.
I am just curious about your process of actually joining the masters program. They usually require 2-3 letters of recommendation etc. How did you handle such requirements?
Second, classroom lectures mainly act as a structured table-of-contents for working through various textbooks.
On a side note, actually studying math as an undergrad, I can't stress enough how much I agree with this, especially in a remote setup.
I think the textbook vs. Pinker/Taleb/Dawkins books can be coarsely classified as "fact books" and "idea books".
Pretty much every textbook (especially introductory ones) is a fact book. They are structured summaries of a field of knowledge, and the goal is to convey as much information as possible. There is no room for extended personal commentary.
An idea book on the other hand does not simply present facts, but fits them in a narrative designed by the author. You don't necessarily obtain the overview of a body of knowledge. It is more like having a long chat with the author, who is preferably an expert in said body of knowledge.
For the learning part, idea books are more effective at getting the "big picture" across, while textbooks require more effort by the reader to either memorize the concepts or see how they fit together at a higher level.
In the end I don't think one can be classifies as more effective than the other since they correspond to different needs.
Consider two AI books, the "Modern Approach" textbook by Norvig and Russell, and "Human Compatible" by the same Russell. A student who wants to do AI research should read the textbook, and spend a lot of time studying it. A layperson who wants to get an overview of the AI field as it stands today, and see what are the possible problems that interest a layperson like himself, should read the latter book, spending much less time than the student.
There will be many people migrating to other services once Roam stops being free. This seems like a promising alternative.
Rule #5: Schedule and limit your exposure
I wrote a simple Go program to email me weekly updates of the RSS feeds I follow. It runs on AWS Lambda with weekly triggers from Cloud Watch and sends emails using AWS SES. [0]
If you are following a high number of feeds, it is a life-changer to go from the mentality of "let's see if there is something new" to "let's wait for the email on Monday".

For the theoretical part of computer science, Introduction to the Theory of Computation by Michael Sipser is the best there is.
It covers three main topics: - Automata theory - Computability - Computational Complexity
What I especially liked about the book was how he approached proofs. When introducing a proof, there is first a short "proof idea" paragraph that emphasizes the main approach behind the proof informally. He then gives out the full, formal proof. For self-study, those proofs can sometimes be intimidating, and not strictly necessary depending on your goals, but understanding the ideas was important to understand the topic.
I recently started a new blog: https://www.thecomputation.com
I simply write about anything I find interesting, and want to learn more about. Topics are mostly from computer science.
I try to refrain from 'Intro to x', or 'X 101' types of articles as much as I can, instead focusing on other aspects. It can be the historical background behind a certain topic, its implications, or a more higher-level treatment.
I am using the exact same router from the same ISP. I was wondering what the problem was when I wasn't able to forward port 22 to my computer for an SSH connection.
I had thought it had something to with the ISP allocating the same static IP to multiple clients and blocking some common ports to prevent collisions (ended up using port 109.. something for SSH). Turns out it was more interesting!
An addition to money and disputes could be 'things beyond your control.' If something is bothering your mind, yet there is nothing nothing you can, or will be able to, do about it, then there is no reason to bother with it.
Regarding the photography books, how does a complete digital archive of a photographer's works compare to a physical book of the same content? Would you still prefer the physical book in that scenario?
I have this USB-C looking like this[0] (not the same one though). The thing is whenever it is plugged into my MacBook Pro, the hub starts to overheat, even when there is nothing connected to it. I once tried plugging it into the MBP adapter and charging my phone through the USB port on it, and it did not heat at all.
I am suspecting it is running some program in the background (a miner maybe). Is there a way I can check if such a program is running?

Even though it covers much more than Corbato and the time-sharing system, The Dream Machine[0] is a great read if you want to learn more about the history of the computers and the Internet.

The number 2 is because it doesn't fetch the posts for each user. You might be seeing posts with a delay of max. 10 min.
Hello!
I created Hackrdot as my first full-scale web project with Rails and wanted to share it. You can read HN, r/programming, and Slashdot. You can bookmark posts and join a mailing list where I will be sending weekly curated selections from those sites.
Any feedback is welcome. I hope you like it.
Would be better visually if bars' lengths were interactively changing as you switched tabs, like what Hackerrank does.[1]
Was there anything that prompted them to ask you to login? I travel through Istanbul a lot (being a native) and I often get asked to turn my laptop on (show the login screen and you are done) without any further questions. Just wondered.
It is one of the most recommended books in book recommendation threads.
