SpaceManNabs··on US Administration announces 34% tariffs on China, 20% on EU
This is blatantly false. You just have to look at Jerome Powell's reasoning in 2018-2019 and just last month!

If Paul Graham is calling out conservatives for being driven stuff other than data, then you know people are losing it lol.

Usually on here you see a bunch of apologia for when republicans do inane economic policy and I am not seeing that bs on here for once...

Guess Trump really wasn't the crypto, AI, chips, wtv you wanna say president lmao. But nah all the naysayers just had TDS.

Guess Wall St and others are going to have to re-learn that sound policy beats vibes.

SpaceManNabs··on How AI is creating a rift at McKinsey, Bain, and BCG
> since it's really just executive insurance

But now you just need 2 associates instead of a team having you as part of their portfolio of clients. The fact that many the consultants are going "AI won't come for us" has me betting against the consultants lol.

SpaceManNabs··on How AI is creating a rift at McKinsey, Bain, and BCG
What stops these consulting firms from replacing the bulk of their consultants with AI if the associates are all just outsourcing every detail anyways?

These people should be a lot more worried lol.

SpaceManNabs··on How AI is creating a rift at McKinsey, Bain, and BCG
yeah doctors and lawyers are safe because of how their lobbies make them necessary as rubber stamps.

AI agents are more likely to replace associates at these firms than software devs lol.

AI agents can't do sql queries a lot of the time, but they sure can autofill the remainder of most excel sheets (and AI agents can't really autocomplete sql queries yet for some reason lol).

Yes, I use claude to code sometimes, but I use claude much more as an assistant to brainstorm tasks and mindmap than actually doing software engineering because vibe coding builds brittle projects. Whereas one-off decks are a perfect use case

Now replacing people that require a license or some other sort of credentials like lawyers, doctors or accountants... That is much harder.

The best way to know something well is to confidently do a project like this incorrectly so that commentators correct you :)

multimodal chain of thought / generation of thought

Nobody has really decided on a name.

Also chain of thought is somewhat different from chain of thought reasoning so mb throw in multimodal chain of thought reasoning

SpaceManNabs··on Music labels will regret coming for the Internet Archive, sound historian says
> then cook up nonsense about how they gave away their identities due to some weird Stack Overflow question no one could ever notice

In case people don't understand why the government can do this, it is called parallel construction and the SCOTUS deemed it constitutional.

Btw this comment is not me approving this behavior. And that last sentence was not a hint of me approving that behavior in secret :). Those last two sentences are a hint of what I think about the scotus on this topic though :)

SpaceManNabs··on Music labels will regret coming for the Internet Archive, sound historian says
Until now, I have always given authors the benefit of the doubt, and presented what they could have said to make their argument stronger.

I do this when hackernews is calling an article stupid and missing some of the salvageable or mostly correct things from the article, so I do some effort to highlight these kernels of truth that most articles have because most authors do have something of value to say.

For the first time on this account on this site... This article is hopelessly naive. Music label executives dgaf. If anything, they want the history gone so that they can charge extra premiums when they release 100 year old songs or for visits to their museums. It is like saying NFL owners regret people not being able to watch the first super bowl game and relive history.

Nah... that is stuff they could sell later if they figure out how.

Expecting music labels to have any sense of democratic music access is almost insulting to artists that have been often dicked by these labels.

Part of me thinks this article is a psyop to make music label executives seem more humane lol.

SpaceManNabs··on The DOJ still wants Google to sell off Chrome
A few years ago, one of the bigger points from the apple earnings was that its first party ads platform 10x'ed (or wtv, can't remember the number) its revenue after apple implemented "do not track" app changes.
SpaceManNabs··on Writing an LLM from scratch, part 8 – trainable self-attention
> also repetition of different explanations of the same concept.

multiple encodings are stronger since they end up fusing into not just more robust and general representations, but also more well connected.

i forgot which neuroscience textbook it was that I read all this from from, but Dr. Barbara Oakley talks about this in her course too so anyone can look through there for more details and sources.

> desirable difficulty

Well regarded in anki, music practice, and most problem solving books (Polya's "How To Solve It"). I think some neuroscience texts also try to formalize it but I don't know enough there to point to a more concrete abstraction of the phenomenon.

> As you re-read the explanation

I suggest something even better. Try to do the explanation yourself from free recall, and when you fail, then re-read and note exactly where and why you failed. This is a mid-level efficiency technique (I forgot the source) compared to free call, active testing, and spaced repetition, but definitely better than plain re-reading.

SpaceManNabs··on Writing an LLM from scratch, part 8 – trainable self-attention
This becomes very obvious to one's self if you learn an instrument or another mechanical/procedural thing. For example, cramming 4 hours into guitar is less useful than 1 hour over 4 days cause of sleep. Sometimes I will struggle with something for quite a bit towards the end of a practice session, and then I will get it right on the first try in my next session on the following day. Hell, there are so many times when I go to my guitar teacher and I tell him "yeah so i practiced this part of the assignment over the past week and I could never figure it out" and then I try to show him the issue and I play it mostly correctly to my surprise.

With something like learning a language, problem solving skills, a code base, new maths, or wtv, it is less apparent because the mind can delude itself, and it is much harder to delude yourself with actual physical movements. You either do it, or you don't...

SpaceManNabs··on Try thinking and learning without working memory (2008)
I will try your app while taking the L train to work for few weeks. Let's see what happens! Should be fun at least.
SpaceManNabs··on Try thinking and learning without working memory (2008)
I am a bit confused by this approach.

From what I've read, the training isn't necessarily transferable. You just get better at these sorts of brain games, which doesn't necessarily mean your working memory is increasing.

Even while reading gwern's blog that seemed pretty positive of this kind of training, there was limited evidence that you shouldn't learn just a new instrument or language or new sort of math discipline.

Why do people keep thinking that "training" can improve working memory?

SpaceManNabs··on Half-Life 2 and Dishonored art lead Viktor Antonov has died
I was going through a rough time in my life when i got the orange box as a freshman in high school.

half life 2 and team fortress 2 and the subsequent intro into the source engine... i really needed them at that time.

Viktor dying makes me sad

SpaceManNabs··on League of Legends data scraping the hard and tedious way for fun
One of the cool things about dota is that opendota and stratz provide a lot of data because steam is relatively open.

it is how i wrote a blog post on generating builds for heroes before dota plus even had the feature!

SpaceManNabs··on Children's arithmetic skills do not transfer between applied and academic math
> My pet theory is that mathematics is largely taught by people who enjoy math

In most of america, until 5th grade, one teacher teaches everything.

In some states, in 4th grade and 5th grade, you do get some segments of specialization in course load, but even then you still have mostly one teacher.

A lot of applied math courses are also taught by people that despise math and just teach that course because it was given to them and they would much rather teach a course in their main discipline.

Somewhat related but very different from the point you raised, a lot of people that enjoy math, especially research, HATE teaching math. I'd actually even venture it is the majority...

People like John Conway were rare. RIP. I miss seeing him around Fine Hall. And now I think of Nash :(

SpaceManNabs··on OpenAI says it has evidence DeepSeek used its model to train competitor
My question is if deepseek r1 is just a distilled o1, i wonder if you can build a fine tuned r1 through distillation without having to fine tune o1.
SpaceManNabs··on My Struggle with Doom Scrolling
> People on reddit write fake stories that push as many buttons as possible; an obviously wrong/evil antagonist, the ridiculous situations that only get more and more extreme to try to attract notice, the righteous moral superiority over the antagonist and their minions, etc etc.

I essentially blocked every subreddit and specifically only open accounts now. I completely agree with you.

One of the best advices I heard is: don't let the algorithm recommend stuff for you.

Never click on the recommend for you page. Or doom scroll.

Any time on these sites, you should know what you are looking for. Never get on there just to browse.

SpaceManNabs··on My Struggle with Doom Scrolling
I used to have an issue with smoking too much weed during the day (I still do).

The only thing that helped was the KitchenSafe / kSafe.

I put my phone in the kSafe during pomodoro sized chunks. If there is an emergency, I can still do calls from my apple watch/ipad. I keep my ipad in my closet so i don't use it for doom scrolling.

It is funny because I random found out that the ksafe got popular from a sharktank episode where the inventor was advocating for controlling binge eating lol.... I found that funny because I've only heard it propose to quit smoking/vaping nicotine/weed.

Still figuring out the interface for other things. When I am at work, social pressures help. Still figuring out a way to prevent myself from opening incognito on my mac laptop and opening hackernews / reddit.

SpaceManNabs··on Metacognitive laziness: Effects of generative AI on learning motivation
As technology gets more impressive, we internalize less knowledge ourselves.

There is a "plato" story on how he laments the invention of writing because now people don't need to memorize speeches and stuff.

I think there is a level of balance. Writing gave us enough efficiencies that the learned laziness made us overall more effective.

The internet in 2011 made us a bit less effective. I am not gonna lie; I spent a lot more time being able to get resources, whereas I would have to struggle on my own to solve a problem. You internalize one more than the other, but is it worth the additional time every time?

I worry about current students learning through LLMs just like I would worry about a student in 2012 graduating in physics when such a student had constant access to wolfram alpha.

SpaceManNabs··on Why the weak nuclear force is short range
> This just...gives no sense at all as to what this stiffness parameter actually is, why it turned up, or why there's what feels like a very coincidental overlap with the Uncertainty principle

Because not everyone has the prerequisite math or time/attention to go into quantum field theory for a rather intuitive point about mass and fields.

This reminds me a bit of how high school physics classes are sometimes taught when it comes to thermodynamics and optics. You learn these "formulas" and properties (like harmonics or ideal gas law) because deriving where they come from require 2-3 years of actual undergraduate physics with additional lessons in differential equations and analysis.

SpaceManNabs··on UK ICO response to Google's policy change on device fingerprinting
This came up on reddit a few years ago and maybe here. There was a case that effectively determined that cdns were not gdpr compliant.

And then everyone ignored this outcome because of the implications. Ofc there is the "legitimate interests" line. Vague enough for a judge to apply as they see fit, but one judge messed up at least one time.
