frob··on Speedsolving Rubik's Cube: 8355 Method
This is absolutely true. I believe he was at least using ZLL at that time, so it only took him 10-15 seconds to figure it out.
frob··on Speedsolving Rubik's Cube: 8355 Method
The guy I learned to speedcube from was so good that we would secretly flip a corner or edge on his cube, challenge him to a race, and he would solve it to the point where only one piece was flipped, curse at us, fix it himself, and still beat us all by at least 10 seconds.
frob··on The SymPy/HackerRank DMCA Incident
This seems like a solid case where Hacker Rank and their contractor filed bad-faith documents and lied under the penalty of perjury. Now that SymPy has $25k of found money, it might make sense to hire a lawyer and counter-sue for damages.
frob··on John Cage Organ Project in Halberstadt
I can't help but think of things like these in a future where there was some sort of gap or loss in human learning, maybe due to a mass-extinction event. It would be seen as a mysterious artifact from the ancients that has been singing forever. Religions and priests would arise to interpret every minor change or fluctuation in the notes since they are obviously a message from a being or being so eternal that they couldn't even slow their speech enough to address in one lifetime, let alone 20.
frob··on Brooklyn Public Library offers access to banned ebooks to teens across the U.S
That's not a reason for banning a book. Libraries are full of books that are completely ahistorical and narrowsighted. Just go look in the political opinion and analysis section.
frob··on Hiring discrimination: a problem for men in female-dominated occupations
I'm working for a company that has over 50% female engineers and it's the best experience I've ever had. Im a guy and I've worked as a tech lead at a FAANG, at a startup, and in academia.
frob··on Hiring discrimination: a problem for men in female-dominated occupations
Can we please change the title to what the paper is actually titled?

"Gender discrimination in hiring: An experimental reexamination of the Swedish case"

frob··on Google Docs will “warn you away from inappropriate words”
> What about situations where being vulgar is appropiate? Can google vacuum up the context directly from the writer's brain

That's why it's a suggestion and not a feature that blocks you from writing whatever you please. It's like how I can type my last name into documents on computers I have never used before: the spellcheck indicator will show up and I will choose to just ignore it.

frob··on Elon Musk makes $43B unsolicited bid to take Twitter private
They absolutely do. The vast majority of the events I interact with these people at are open to the public with announcements in local news papers. They have dedicated communication channels. The last person I helped spent every Saturday for two months hanging out at the town dump to meet people and hear their concerns. He is planning on making it a monthly event going forward. It can be amazing how empty town, village, and county board meetings are. Show up, state your opinion in a respectful manner, come prepared with an informed argument, and take the time to chat with people afterwards. They'll remember you and if you have a consistent track record of being level-headed and productive, you can start to carry some real influence.

Like much in life, half the battle is just showing up.

frob··on Elon Musk makes $43B unsolicited bid to take Twitter private
> Now if you're not on the big platforms your opinion may as well not exist.

I'm no so sure about that. Since leaving social media, I've become quite involved in local politics. I now know some state legislators on a first-name basis and multiple directors of state departments in multiple states. I can call up people I've helped get elected and get my thoughts right to them. I find my opinion to effect much more change than it did when I was shouting into the digital void.

frob··on Elon Musk to join Twitter’s board of directors
No, it is literally a private company. Which is why we are having this discussion based off of SEC filings.

Edit: sorry, I mixed up public company and public good. Twitter is a public company, but not a public good.

frob··on Young women earn more than young men in several U.S. cities
In the middle of the article this is literally the discussion about, it literally has a chart showing that young women earn 93% of what young men do when looking across all metro areas in the US.
frob··on Young women earn more than young men in several U.S. cities
I'd hardly call the 102% ratio in NYC "more" in this context.
frob··on Young women earn more than young men in several U.S. cities
In NYC, young women earn 102% of what young men do. While that is technically more, I would count it as equal.
frob··on Young women earn more than young men in several U.S. cities
"Several" is doing some very heavy lifting here. According to the paper cited, it's 22 out of 250 metro areas (or 9%).

Another way to put this is that in the vast majority of metro areas, young women DO NOT earn more than young men. Even when you look at the areas where young women do outearn young men, it is not by a lot. For example, in the NYC area, young women earn 102% of what young men do. To my ear, that's parity.

frob··on The Scottish Play
As a techie, I've always made it a habit to walk out onto the middle of the stage and shout, "Macbeth! Macbeth! Macbeth! There, now it's done with!" at some point during tech week.
frob··on Mounting evidence for a 95 GeV Higgs boson
Everything here is at or below 3-sigma confidence, and it's not even clear if that's a local search confidence (i.e. when you know the mass to within a small %) or a global search (where you don't know the mass and are just looking all over the place for an excess which inherently makes it more likely you find SOMETHING which makes your confidence lower). The world of particle physics is littered with the graves of 3-sigma excesses.

At this point, there is basically nothing to see here. You will do yourself a favor by just moving along.

frob··on Scooping the Loop Snooper (2000)
Pullum keeps a slightly updated version of this poem on his website: http://www.lel.ed.ac.uk/~gpullum/loopsnoop.html

It adjusts the phrasing in a few places to make the meter flow more naturally. Apparently it also fixes a small error in the original proof, which, for the life of me, I cannot find.

I've used this poem to teach the halting problem to a variety of people for almost a decade and a half. Reading the one linked here just didn't sound right.

frob··on Nvidia Grace CPU

The author notes all of the issues with this implementation, but I've just got to note this summary of the halting problem: http://www.lel.ed.ac.uk/~gpullum/loopsnoop.html
frob··on What Is IO Monad? (2018) [video]
`Monad is just a cute name for flatMap`

Hahaha! I swear this is exactly how I feel halfway through every monad tutorial I find.

frob··on I have no capslock and I must scream
To be fair, I banished capslock from my keyboard in favor of ctrl 17 years ago and haven't looked back.
frob··on Glorified electric golf carts for all
I grew up in a small town built around two golf courses. It was a very conservative area, but the electric vehical rate was also very high because about half of the people there had golf carts and many of them were electric. People drove them everywhere and would often send their not-quite-16-year-old kids off in them. Many homes were designed with a 3rd small garage door specifically for golf carts. The local state rep even got a bill passed to change the law so it was legal for them to cross the highway at a stop light, which was reasonable as horses and buggies were permitted to do so. You probably only got 20ish miles out of a good charge, but that's more than enough when the farthest part of the community is barely 2 miles away.

Point being, no one sold this community on golf carts because they were electric and efficient. People loved them because they were affordable, simple, and practical.

frob··on Holon
This reminds me of analytic functions. If you know the value of the function for an infinitesimal region, you know the value everywhere.
frob··on Facebook loses users for the first time
Bingo. I'm done. It's over. No matter how much I want to hop on and rage about the current issue of the day, I just can't and it's not worth pinging my former teammates there for the Nth time trying to fix it.
frob··on Facebook loses users for the first time
I fall into a 3rd category: I used to log into FB once a month or so to check in. For some reason, they decided I was a fake account (despite working for them for 4.5 years) and asked for my ID. The resolution on my 10-year-old MBP was too low for FB's contractors so they rejected my ID 3 times and I seem to now be locked out of my account indefinitely.

Definitely in the top 10 best thing to ever happen to me.

frob··on Impacts of lack of sleep
I installed an IR sauna a few months back. I use it almost daily. Sleep has been fantastic since then and I recover from workouts much more quickly. Stretching is also much easier in it and I've easily increased my bent-over stretch by 3 inches since I started focusing on it.
frob··on Impacts of lack of sleep
For me, the best thing to induce a good night of sleep is exercise. It can be at any time of the day. Some of my best night have been after I finished an hour-long heavy weight workout 45 minutes before going to bed.
frob··on QR code scammers hitting on-street parking in Texas cities
I've noticed a similar thing on rentable bikes in SF and NYC. People don't put the qr code over the existing bike one, but they put it near enough that your QR reader might pick it up by mistake and open up the order site for a pizza chain. Fortunately, when I'm using the bike app directly, these codes are ignored, but new users don't necessarily have the app yet.
