arn··on Clubhouse Is a Cargo Cult
Early Quora was remarkable by how many high profile people were answering. That was a big part of its early appeal.

An example I still remember. Someone asked How much it cost for AOL to distribute all those CDs in the 90s... and Steve Case answered!

arn··on Law school applicants surge 13%, biggest increase since dot-com bubble
Apparently med school applications were up 18% (in 2020). Which surprises me, I would think COVID might have scared more people off.

arn··on Google and Facebook mandate vaccines for employees at U.S. offices
But there are more vaccinated people than unvaccinated people, so it’s proportionally not “almost as much chance”.

Ultimately when enough of the population is vaccinated, you’d expect the majority of hospitalizations to be vaccinated.

arn··on Some stuff I found interesting about number theory research
Prob a few reasons. This was written in a very conversational tone.

If he wrote it in a blog, it would read weird or he’d spend a lot more time on it. I’ve started blog posts before and just kinda gave up when it didn’t seem like it came together well.

arn··on “I would buy a Mac today if I was not working at Microsoft” (2004)
There are legit rumors that Apple is specifically killing the Touch Bar as well.
arn··on Bezos donates $100M each to CNN contributor Van Jones and chef Jose Andres
This is not true. He realized $4 billion in gains in that ProRepublica article people referenced, and he regular sells shares.

arn··on Tax details of US super-rich allegedly leaked
Well, estate tax already exists.
arn··on Tax details of US super-rich allegedly leaked
What's your personal 'true' tax rate? Taxes paid divided by all income and all gains (unrealized capital gains, increase in real estate value, etc...).

I'm sure you don't know. No one knows or has a frame of reference. It was chosen to emphasize the narrative. It's like comparing the carbon/waste from mining, manufacturing, delivery and use of a electric car vs. the carbon from burning a tank of gas -- and saying "ah ha! the total lifetime of an EV is worse for the environment than driving around town in a gas car"

arn··on Tax details of US super-rich allegedly leaked
Seems the solution to that (if u think it’s a problem) is eliminating step up basis.

The reason that works is that basis is reset at death.

arn··on Tax details of US super-rich allegedly leaked
It conflates income with unrealized capital gains.

You can make an argument that income and capital gains should be taxed at similar rates, but it feels like they are being purposely misleading in their presentation, when they use unrealized capital gains as the denominator.

No one else’s taxes are viewed through that lens.

arn··on Zapier reached a $5B valuation with $1.3M of funding
> Who would spend hours watching people play video games

Ask yourself who would spend hours watching people play sports, and it might not seem so foreign.

arn··on I Am Bezos
This is confusing. I couldn't tell what it was counting.

"Change in Net Worth" or something would make it clearer. But it's still not great.

arn··on Tell HN: A case of negative SEO I caught on my service and how I dealt with it
Browsing through your SEO results. I also don't think the negative SEO is necessarily what did you in.

You have a very straight forward value prop. "Next episode" of some-show. I think these sort of optimized results are probably things that Google has been algorithmically adjusting for.

Looking at the Ranked 1-3 terms you dropped for, it seems you dropped some pretty big terms and even keyword terms.

You were #1 for "seal team next episode", but now you rank #3. #1 got replaced by CBS's page, which is arguably a better result.

"black clover new episode" also dropped from #1. Replaced by Wikipedia.

"the good place next episode" similar story.

I don't know what the best move is here. Algorithmic changes are really hard to combat without major changes and even then, you don't have a ton of room to wiggle with next-episode content.

arn··on Centering in CSS
text-align:center does NOT entirely replicate <center>. And has been a source frustration for many.
arn··on M1 Macs: Truth and Truthiness
As others have said, I was simply offering a suggestion to help debug, not passing judgement on adblockers.

I have had Safari open for 23 hours on my M1 MBP, and it is using ~800mb of memory right now. Extensions are the most likely culprit.

arn··on M1 Macs: Truth and Truthiness
If you are using an ad block or other extensions, that is likely the cause. I can't find specific reference, but try turning those off.

arn··on What would happen if computers never got any faster?

The original Atari 2600 Pac Man was notoriously bad. Someone made a much better version in 2014.

arn··on Google to end the “top stories carousel” benefit to AMP next spring
Apple sort of does this on mobile Safari and its a frustrating / unexpected experience.

If you are on a website in mobile safari, and you hit the share button, and select Copy. What gets copied into the clipboard is actually the Canonical url rather than the actual one you are at.

So for /amp/ pages, it ends up copying the non-amp url.

imo, it's a bad experience because sometimes canonicals and non canonicals aren't exactly the same. For example, if I'm looking at a specific filter or sort, then it might make sense for the canonical to be the non-sorted version. But if I'm sharing a specific url, I want it to share exactly what I'm looking at.

arn··on Covid vaccine: First ‘milestone’ vaccine offers 90% protection
Looks like the government “pre ordered” vaccine from Pfizer but Pfizer didn’t actually accept funding for development:

arn··on Is it time to stop counselling patients to “finish the course of antibiotics”?
Resistance is not as black and white as you suggest.

https://litfl.com/minimum-inhibitory-concentration/

It’s more of a spectrum of concentrations. A resistant bacteria is one that doesn’t grow above a certain threshold. But longer exposure or higher concentration will change the effectiveness.

arn··on Should I Use a Carousel?
This page was designed to be intentionally frustrating.
arn··on Should I Use a Carousel?
Facebook and Instagram use carousels for their Stories feature. Google uses carousels for News stories and product results. Are they the exception and if so, why? Or are they not aware of the user data?
arn··on The Inheritance Tax Is Far Too Low
But there's a large exception. You won't be taxed on that amount. You presently get the first $23 million tax-free before any inheritance tax kicks in... and then only for the amount above $23 mil.
arn··on People think they're calling restaurants directly but Grubhub is getting a fee
I don't know about that. Not that it's easy to measure. But I feel that if I go to a restaurant and it's closed outside their normal hours inexplicably... I am definitely less likely to come back.
arn··on Cloudflare Dashboard and API Service Issues
Can't clear our cache via api or manually, so our cached HTML pages are stuck until the natural expire happens -- which are set somewhat long. Not great for a blog / news site. for example, if we publish a story, our front page won't reflect it.
arn··on How Prince of Persia Defeated Apple II's Memory Limitations [video]
He posted some "making of" videos when he remade the iOS version of Karateka.

I really enjoyed this video explaining how he got around making the gameplay easier (not just 1 life) but also made it make sense to the story.

You have 3 lives... but 3 different lives:
