augustt··on Going to elite Indian colleges improves earnings, but not test scores
Well there's the Putnam competition, which MIT has been completely dominating recently (https://kskedlaya.org/putnam-archive/AnnouncementOfWinners20...).
augustt··on Western Digital is trying to redefine the word “RPM”
They'll start with the same silicon design but manufacturing variability requires them to bin the chips based on functionality & performance, which is how you get all these different models.
augustt··on Belarus opposition leader Maria Kolesnikova 'snatched from street' in Minsk
If he does speak up it will probably be to brag that he had the idea first to snatch protesters up in unmarked vans.
augustt··on App Review process updates
Its core market does not even know what side-loading refers to.
augustt··on Google is apparently taking down all/most Fediverse apps from the Play Store
I don't see anything that indicates these values should be opposed. I've seen controversy over this before and to be honest it mostly seems to be people projecting their own idea of what the left thinks - that "white values" implies they are not "black values" and that all whiteness = bad. Then they conclude from a decent summary of dominant values in America something like /r/conservative's take: "#DefundSmithsonian ... We are paying for white genocide with our tax dollars."
augustt··on Google is apparently taking down all/most Fediverse apps from the Play Store
Any evidence at all that self-improvement is under attack, or are these all euphemisms for something else? Maybe "pick friends based on shared values" means "I wouldn't let my kids play with kids from the other side of the tracks", which should indeed get some pushback.
augustt··on Blanked-out spots on China's maps helped us uncover Xinjiang's camps
> the Uighurs in China aren't treated worse than blacks in USA

I'm gonna stop you there. At the very least you can speak up in the USA without getting disappeared.

augustt··on Securing Lasting Freedoms for All
Morality and wanting money aren't mutually exclusive - see also: minimum wage.
augustt··on 2,445 IBM Employees Openly Condemned IBM for Enabling Racist Regimes
Like trying to get five innocent black boys executed and maintaining his position to this day? And of course his reintroduction to politics was riding the birther movement, which was almost comically racist.
augustt··on The Fundamental Axiom of Floating Point Arithmetic
I'd say not only is fundamental, it's pretty much the only tool you have to start the analysis of an FP algorithm. If you want to analyze a naive sum algorithm for instance you do that by recursively applying the a ⊕ b = (a + b)(1 + ε) rule and figure out how the epsilons bubble up - the result being that the error is linear with the sum length.
augustt··on Introducing Instagram Reels
At least an American Samsung would be useful, if it means bringing back semiconductor manufacturing to the US. Better than having our brightest engineers work on copying each other's photo apps.
augustt··on Some Fundamental Theorems in Mathematics (2019) [pdf]
This is awesome, although a bit in the old sense of the word, since it's scary to see entire courses I've taken distilled into one result that I probably couldn't even attempt to prove now.

aside: wonder why for group theory (51) Lagrange's theorem is only stated for cyclic subgroups, instead of any subgroup.

augustt··on The Fundamental Axiom of Floating Point Arithmetic
Yep the term for this is catastrophic cancellation, which doesn’t invalidate the axiom.
augustt··on Mail delays hit Philadelphia residents, short staffed USPS struggles to keep up
> 2. Disenfranchise voters (a relatively recent campaign)

Recent as in it started the instant the 15th amendment was passed.

augustt··on A College Degree Is No Guarantee of a Good Life
Some random classes that come to mind:

Electronics: https://www.google.com/search?q=6.115+final+projects

Interactive music: https://vimeo.com/user42907764

Product design: https://www.youtube.com/watch?v=RqKSAz3yxMM

augustt··on Online classes are not worth cost of full tuition
Well at the very least you'll learn how college is spelled.
augustt··on Terry Tao on some desirable properties of mathematical notation
Honestly what are you talking about. You can simulate for 100 years without finding a counterexample, but that doesn't make a proof. The whole point of math is to understand why things are true, not to just be satisfied that it seems true.
augustt··on How objectivity in journalism became a matter of opinion
The media indeed. It was them who told the GOP to try to put a woman who could not name a single supreme court case one step away from the presidency in 2008. The party of personal responsibility is not personally responsible for being seen as complete insane in sensible countries.
augustt··on How objectivity in journalism became a matter of opinion
Would that 'science' happen to be the very productive discussion of reminding transgenders of their birth sex every day a la Ben Shapiro?
augustt··on [dead]
That was absolutely the idea, try to force a win-win scenario for his base. Either he gets rid of foreigners (win) or colleges reopen and corona isn't so bad (win).
augustt··on Int. students may need to leave US if classes are 100% Remote
So, still immoral. It's gatekeeping upwards mobility with absurd prices.
augustt··on Show HN: ScotusWars – see your state's win rate in state vs. state court cases
It seems there's an error when you click on MA
augustt··on Decision for 2020-21 Academic Year
Finally, now the rest of us can wait for our administrations to copy them (at least MIT has been following their every move).
augustt··on The Unplanned Impact of Mathematics
Like ∇^2 u = Δu = f? It's not really cryptic, it's taught in multivariable. And it's not done to look sophisticated, it's so that you can instantly recognize that it's Laplace, or Poisson, etc.

If I tell you B = (dA_z/dy - dA_y/dz)i + (dA_x/dz - dA_z/dx)j + (dA_y/dx - dA_x/dy)k do you instantly see what operator is applied? That's why you just write B = ∇×A.

People presenting ideas in shorter notation is not showing a lack of progress - usually it's the opposite. In old optimization papers people would write out the entire normal equations, entry by entry. Not really insightful at all, compared to A'Ax = A'b.

augustt··on The Unplanned Impact of Mathematics
I'd say this is generally not true, at least in math. There's definitely poor notation and misnomers that come from tradition, but it's hardly deliberate as "obfuscation" implies.
augustt··on The Unplanned Impact of Mathematics
A nice example is that Gauss realized in 1805 that Fourier transforms could be made less tedious by subdividing the problem (n=12=3*4 in his case), 160 years before Cooley-Tukey.
augustt··on The neoliberal era is ending. What comes next?
Especially in the tech era? What does that even mean... you can grind on sharing economy apps 80 hours a week? Or should every man/woman/child enroll in javascript bootcamps?
augustt··on MS will ban Forza players who add the confederate flag to their digital cars
People don't want to see hateful shit in video games. You do not have god-given right to be shitty in a car game. Pull yourself up by the bootstraps and create your own community that tolerates hatred.
augustt··on How the 2021 Ford F-150's onboard generator works
Yea but tools usually aren't run at 400V. Still going to have some efficiency losses when you buck it down.
augustt··on Turkey determined to control social media platforms, Erdogan says
Columbus has been a point of contention for a while now. Regardless, corporations are not saying BLM because some tiny segment of the country thinks that. A majority of America supports the movement, and that's being reflected by PR now.

The last line of defense for conservatives is "well actually there's a silent majority that thinks otherwise" and "actually most people don't care, they're just virtue signaling". And this works well when the Fox+ apparatus are the ones creating boogeymen out of minor things like CHAZ.
