kr0bat··on Localsend: Open-Source Airdrop Alternative
Yup, I use fsquirt.exe to transfer small files between my phone and laptop. But I have to grab a usb cable for anything bigger than a low-res picture.
kr0bat··on "Full Self-Driving" doesn't imply autonomy, Tesla engineer says
Android's always-on display turns off most of the screen, besides a clock and set of notification icons. And the display constantly shifts to avoid burning out the screen.

It looks like iOS, on the other hand, just dims your lockscreen slightly? I can see why they'd have to get smart with how often they leave the display on. It'd be distracting while you're trying to sleep and sounds like a battery killer. In a way, Apple may be using the phrase "Always-on display" more literally than you'd expect, even if it is less practical.

kr0bat··on How to assert for fun and profit (2022)
In this example the assert is less explanatory than a comment. Why do

    if (condition):
        ...
    else:
        assert(!condition)
        ...
When you could instead if (condition): ... else: #if (condition) ...

Or otherwise explicitly comment the condition that was checked earlier. At least then if the comment is unchanged, whoever is touching your code will assume the comment is outdated, rather than assuming that you're asserting that x should be some undocumented magic number.

kr0bat··on How to assert for fun and profit (2022)
Honestly, my first question was "why not use a combination of user-created types and exceptions to ensure program validity." But I get the impression that asserts are used for alerting programmers to their own syntactical and logical errors; unlike exceptions, which can occur in logically proper code.
kr0bat··on The Prosecutor's Fallacy (2018)
>Notice that at 0.02% prevalence the two conditional probabilities differ by 97% but at 20% prevalence the difference is only 3%. Therefore, the Prosecutor’s Fallacy is not an issue when the prevalence (or prior likelihood of guilt) is high, because the conditional probabilities are similar.

Whoa I think the point makes sense but I'm not sure about the data used to demonstrate it. The difference between probabilities at 20% prevalence were 1% and 4%. That's not a 3% difference, that's a 3 percentage point difference that results in a 400% difference in probability. That's not similar at all.

kr0bat··on Permission Slip: Consumer Reports app to take back control of your data
>They had a firewall between themselves and the manufacturers of products they review. They would buy cars themselves, then review them instead of getting a "perfect" car loaned and managed by the company that created it.

This is still very much the case for all the products they test, cars or otherwise. According to people I know who work there, they don't even order products to their office, lest a company sees the address and ships a superior product.

kr0bat··on Generative AI could make search harder to trust
This is essentially the service Reuptation.com claims to provide. Jon Ronson's "So You've Been Publicly Shamed" describes the site games SEO to flood the search results of controversial figures with banal nothing posts[1]. The difference being that actual humans had to create that content.

In the near future, the web could become opaque with LLM schlock, but at least it may grant people a right to be forgotten.

kr0bat··on Students made Oxford murder capital of late medieval England, research suggests
I wouldn't even disagree with a lot of what's you're putting down, but it's not very relevant, no? Even if you believe that we've "outsourced violence" - and honestly I agree, it's all to easy to forget that a lot of our first world material conditions are predicated on cheap third world labor - there's still a difference between global exploitation, and stabbing a man to death over public urination.
kr0bat··on Students made Oxford murder capital of late medieval England, research suggests
So we're living in the least violent times of human history, aren't we? The murder rates found in Oxford was higher than even the most violent contemporary American cities, and the conditions of some of our cities are absolutely tragic.

What's made the world so much more peaceful? Improved material conditions?

kr0bat··on Discord as a filehost will no longer be possible by the end of the year
How many major social media sites try to prevent this behavior? Facebook links expire[1]; but Reddit, Tumblr, and Twitter all generate seemingly permanent image links.

Also semi-related fun fact, I think most sites lack authorization checks when accessing images via direct urls. A logged out user can follow direct image links from private accounts/servers/subs on all these sites, including Discord. Not like that means much of anything security wise (if you have the url you likely had access to the image)

kr0bat··on Y Combinator CEO Garry Tan’s War on San Francisco Politics Has Only Just Begun
A politcal landscape of career politicians and undignified, multi-millionare ideologues may be better than a landscape of just career politicians; I'm not sure if it's much better, however.
kr0bat··on Year after BLM protests, S&P 100 added 323K jobs – 94% went to people of color
"Breaking up homogeneous communities?" What a torturous way to describe desegregation.
kr0bat··on Year after BLM protests, S&P 100 added 323K jobs – 94% went to people of color
40% of new hires are hispanic. Funnily enough, hispanic is counted as a race even though one can easily be hispanic AND white. And the fact that black and "other race" are both options makes me assume that many of these hispanics might be considered white (at least on a census). There's nothing stopping a white hispanic person from seeing the social pendulum swing and switching their self-reported "race" on their job application.

Additionally, it looks like about a 50% of growth came from "less-senior jobs" This sector lost 19k white americans, while gaining 176k poc. With 60% of that sector's growth coming from hispanics. This sector houses "Sales, laborers, service workers and others." The higher sections that house "roles that typically require degrees" show different hiring patterns. With white americans making gains (that I believe are still disproportionatly low to their share of degree holders? Idk, someone else can do the math), and Asians making the most gains among managers and professionals.

I wish Bloomberg had mentioned how many people are actually employed at S&P 100 companies, I bet <150k professional+ highers is a drop in the bucket compared to their workforce.

Bloomberg also makes note that this trend may not have held past 2021 due to DEI being disincentived politically.

The article displays and explains its data well, though I wish they would have brought up the fact that Hispanics can totally be white. And given the title and the standfirst I expect this to start a lot of angry discussions online. Personally, I'd guess that a lot of the growth simply came from white hispanics and America's rapidly growing, highly educated asian population.

kr0bat··on A journey into the shaken baby syndrome/abusive head trauma controversy

  I came to realize that there was a long-standing scientific controversy in the field, and I felt that I had no choice but to get to the bottom of things myself. Although I am not a medical doctor, I hold a PhD in neuroscience and am familiar with critically reading scientific literature. I decided that I would invest as much time as necessary to learn everything I possibly could on the subject. At that point, there was nothing in my life more important than finding out what had really happened to my son.

kr0bat··on Google is picking ChatGPT responses from Quora as correct answer
When do you stop digging?

When you reach a primary source? If I can't get a cheap, reliable answer to a simple question without looking into a potentially dense primary source, then online search becomes about as useful as a library card. Besides, not every domain is expected to include primary sources. Did the author of this recipe really think that a wok is better than a skillet for fried rice, or is this the written delusion of a gemerative AI?

Do I instead only look for answers found in reputable sites? Aggressive SEO has made badly formatted sites indistinguishable from GPT sludge. Personally, I don't trust answers from sites I haven't heard of before my search.

kr0bat··on LARPing and Violent Extremism
D) Irony poisoned teenagers
kr0bat··on LARPing and Violent Extremism
They used the term LARP a lot more literally than I expected.

  Although the history of LARP as a legal defense is narrow, the authors share the concern that it may soon become commonplace. Early attempts at such a strategy have been made by a defendant acting alone or in loose cooperation with members of a fantasy group who knew each other only in the virtual world, claiming “artistic expression” to excuse threatening language.

I can see this being a big problem with memes in the immediate future. Does the FBI have a page where they attempt to distinguish edgy memes from genuine calls to violence? This is a relatively benign example, but there are TikToks where users pretend to have fantasies about taking officer's service weapon. Sure they're all jokes, but modern internet humor is deeply ironic; I'd imagine there are plenty of genuinely violent people making seemingly ironic memes. I'd also imagine that there are nonviolent memers disseminating genuine violent ideas and vice versa.

Going from discussing the curvature of the Earth to the finite speed of light wasn't to dunk on the student, it was to demonstrate the increasing relative correctness of our universal theories.
