jokellum··on Note-Taking and Personal Knowledge Management
I don't know your specifics, so I'm going to reply with what I've learned about learning:

I found reading a textbook, and typing notes into a dumb markdown file with the textbooks name is good enough. Typically: definitions, quotes, and personal thoughts while reading. Did this for stats/comp sci/etc. Obsidian + markdown worked for that, even without plugins. Being able to text search is useful, which is why I don't hand write.

Anything beyond that you have to be cautious about paralyzing yourself from trying XYZ PKM.

Theres a quote from stephen king that goes somewhere along the lines of "during first draft don't try referencing or fixing grammar because it breaks your train of thought". I think similarly, when learning something, choose the thing thats most out of the way (usually the simplest) that is least likely to break your train of thought.

In terms of tracking how much you're learning, I'd be very very slow and incremental in what tooling/methods you pick. For me, I just trust myself after reading/notetaking a textbook. Usually homeworks get very easy which is a good sign. Being able to explain what I learned to someone else is a good sign.

Note Brennan, who wrote the article this one is responding to added an update: https://brennan.day/what-have-note-taking-pkms-accomplished-...

Brennan could have gone about a better more interesting route that I would have agreed with more, instead of incorrectly blaming Obsidian and conflating it with a specific PKM framework.

I am an avid obsidian user and have avoided most PKM stuff, and instead just developed a PKM that works for me through slow incremental improvements and changes. The beauty of Obsidian is the plugin eco system, and I even was able to develop my own plugin for what I specifically wanted. I think that's what Brennan basically talks about in his "Question 3" section where he favors just making your own.

I do think that there is "choice paralysis" that people may have when jumping into Obsidian and trying to add plugins too early instead of discovering what works (and what doesn't) for them first.

His final point:

> After researching... well, research, a part of me feels a sense of relief. The fact is that I've been using ad-hoc, improvisational methods for research and knowledge management for my entire life. It's clear I haven't been missing out on deeper, richer understandings by way of more complex knowledge management systems.

I completely agree with this, and Obsidian is one of the best tools to do this! And Brennan corrects this in his update at the end of his article.

jokellum··on Doing well in your courses: Andrej's advice for success (2013)
> Places with a lot of background noise are bad and have a research-supported negative impact on learning. Libraries and Reading rooms work best.

This was horrible advice for me and caused my a lot of grief for many years wondering why I still couldn't focus.

Nothing against Andrej, part of the reason I hate this advice is that this is very common advice for what your environment should look like. This was advice given by study workshops at my college. I'm sure this works for a decent chunk of the student population.

Quiet places cause me to mentally drift into outer space and I just zone out.

You know what is a great environment? Semi-busy coffee shops + headphones + instrumental music. I'm able to consistently lock in for 4-5 hours. When I go back to my "nice quiet home environment" I get distracted immediately and refocusing is super hard.

Like I said, this is standard advice that works for a portion of the population, but I think this makes a ton of other people in the same boat as me feel lazy/discouraged/unfocused/stupid losers when in reality "nice quiet places" might not work for them.

jokellum··on Agenda Behind the Facial Recognition Tech Used by ICE and the FBI Revealed
I'm sorry, like the other comment said you're still both-sides-ing.

States / cities (democrat or republican) sent riot police, which is something they have always done. How they handled protests is worth criticism e.g. I don't like that they use curfews to suddenly make protesters breaking the law. I don't like the use of tear gas on otherwise peaceful protestors. As a note, these are state / city officials not federal guidance typically.

However,

The current administration, Donald Trump, the president of the united states, and the top most members of his cabinet, as a federal, top-down policy will:

- Automatically identify protesters

- Arrest them for simply saying things the admin doesn't like.

- Bypass due-process.

- Will ship them to a gulag outside of the united states.

- Are on track to be found in contempt of court for refusing to bring back a lawful resident.

Both sides are not the same here. Name me a democrat president who has done equal or worse what the trump admin has done.

jokellum··on Dozens of U.S. academics lose grants from Minerva Research Initiative
The article doesn't demonstrate Obama stealing Congress's power of the purse. Can you show me an example?

I'm quibbling with implications of "there's nothing new, they're both the same".

In the article he can sign an executive order to make college more affordable, but this is using Congress's budget allocation, and powers provided for the department of education though is it not?

Trump is literally dismantling departments approved by Congress, and using the budget in completely different areas as far as I can tell. He's not simply redirecting what X department should be doing, as compared to Obama.

Can you expand on this?

jokellum··on Wikenigma – an Encyclopedia of Unknowns
This is something that confused me also. I feel like this is a reasonable argument.

My only criticism I guess would be that this is unfalsifiable, so for the time being it's more productive to see if there's any possibility to explain that within the observable universe.

jokellum··on Ask HN: What skills do you want to develop or improve in 2025?
Similar boat. Started pretty successfully in AI/programming since I've always wanted to do that. But romance is pretty bad. I also agree about the solitary hobbies vs social ones.

Started doing sports / gym this year, and will probably continue that next year. I've thought about taking a drawing art course or cooking course.

jokellum··on Why making friends as an adult is harder
I work as a remote software dev. Joining a volleyball league + run club definitely helped massively for me.

> Again, making connections and friends is easy. Being around the same people regularly is difficult.

Agreed, 90% of the difficulty making new friends is showing at the same place/event regularly. Remaining 10% is actually being someone people want to be friends with.

jokellum··on Is the Q source the origin of the Gospels?
> Until such questions are answered, a God is still quite reasonable.

I'm sorry, what is the monkey typewriter supposed to prove or disprove about God?

The original post isn't even about evolution, its related to textual and historical analysis, so I don't see how this is related.

Even worse, even if evolution disappeared as a theory, that wouldn't change the truthiness of specifically the claims / myths in the bible, and wouldn't in anyway make the existence of the Christian god any more likely.

jokellum··on Adobe starts roll-out of AI video tools, challenging OpenAI and Meta
If you use their product, per their tos, my understanding is they can train on their customer data at any time. In other words, if you use their product, they automatically have license to train on your art.

I think the only statements saying that they don't train on their customer data is from their CEO, but unless they encode it in their tos, that doesn't really matter.

Louis rossmann video talking about this: https://www.youtube.com/watch?v=5euh13nd10g

Had a decision earlier this year to buy a Tesla vs a dumber car. 2019 Silverado I think has the best middle ground on terms of "smart" tech that is still easy to repair and doesn't sell my info to insurance companies.

jokellum··on Joe Biden stands down as Democratic candidate
Fair point, meant to specify "anti biden, pro trump".

I didn't think he was fit for office either (first point), but I'm glad he's being replaced.

jokellum··on Joe Biden stands down as Democratic candidate
Agreed.

Hasn't the number one thing anti-biden people have been saying is that he isn't fit for office due to his mental state?

Its bizarre seeing them flip to calling this a coup as if biden stepping down is suddenly an illegal/unconstitutional thing.

I consider this "concern trolling".

They said for 4 years how he's barely mentally there / can barely speak / not fit for office, and then when the Democratic party pressures him to step down, they go all surprised_pikachu_face.png.

In this case, the existence of earth is an even number, so I don't see how this is a fallacy.
jokellum··on Daylight Computer – New 60fps e-paper tablet
Yeah but I'll be viewing the PDF on my phone / computer, so being able to annotate in different colors even if the display is BW is important to me.
jokellum··on Daylight Computer – New 60fps e-paper tablet
I like my rm2, but 2 of my biggest issues are:

- Syncing changes I make to PDFs to Google drive is tedious

- For some reason there's a restriction of color when drawing on the PDF. Even if The tablet is black and white which is fine, I want to be able to select a wide range of colors since ultimately I'll want to be able to view the PDFs on a legit RGB computer.

What does this workflow look like on Daylight?

jokellum··on SB-1047 will stifle open-source AI and decrease safety
It's not at all like saying that. The concept of bridges is thousands of years old at this point with well established best practices, and a dense knowledge base on what can go wrong and how much damage can occur if built incorrectly. We aren't at the stage of "bridge innovation" where we don't even know what a bridge collapse looks like. We know very well the cost, threat to lives, even timeline that a poorly built bridge can cause.

I'm not against legislation regulating AI, but it needs to be targeted toward clear problems e.g.: stealing copyrighted material, profiling crime, face recognition, self driving vehicles, automated "targeting" however you want to interpret that.

I want to point out above are some awful uses of AI that are leveraged mostly by closed, proprietary entities

jokellum··on AI is a 'Glorified Tape Recorder,' Says Theoretical Physicist Michio Kaku (2023)
> No, human nerve cells are not "ridiculously simple." The idea that neurons = transistors is old-fashioned

That's not what the OP or the literal quote you pulled from them said. They said a single neuron is ridiculously simple _relative_ to what a clump of them can do.
