pdog··on Starting a crypto project
> It's interesting that he cannot prove that his "black swan" strategy has ever been actionable for his own or anyone's portfolio, how to use his theories to make significant money vs. normal strategies...

Mark Spitznagel, a cofounder of Empirica (Taleb's old fund), went on to start Universa which did pretty well with similar theories (tail-risk strategies and insurance via options against extreme market risk) in both the 2008-2009 period and last year, when they booked a huge return. So there's some evidence that the theories work to produce uncorrelated (or negatively correlated) returns that outperform the market[1].

pdog··on CDC panel recommends resuming use of Johnson and Johnson vaccine
> That’s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19.

Since when has not knowing something been justification for intervention?

Given that people have been getting sick from COVID-19 for at least as long as vaccines have been available for testing, shouldn't experts have a reasonable understanding of whether previously infected people are as protected as recently vaccinated people, or how often (or rare) it is that people can be infected with the virus again?

pdog··on Apple Approves Parler to Return to App Store
The chilling effect is real. Even if service is reinstated, the precedent is now that major platforms can arbitrarily censor your news stories for weeks, shut down your servers, and remove your apps from their app stores. Why would anyone build anything remotely controversial on these platforms?
pdog··on Coinbase Announces Listing Date of Its Stock on the Nasdaq
> Because of things like Apex Crypto, it feels like pretty much every stock broker app will now let you buy Bitcoin and they'll do it with lower fees than Coinbase.

Which stock broker app lets you deposit in Bitcoin? Or withdraw your Bitcoin to your own address?

pdog··on EU experts to say nuclear power qualifies for green investment label: document
If you're worried about nuclear waste, why not build small nuclear reactors way out in the desert and encase them in concrete for a couple hundred years once you're done with them?
pdog··on Intel Core I7-11700K Review: Blasting Off with Rocket Lake
No ECC support means it's totally useless for workstation workloads.
pdog··on Tech barons like Jeff Bezos want to colonize space and the oceans
> The internet is a bunch of private fiefdoms.

For $7 a year you can host a website that's accessible from anywhere in the world. Things are better not worse.

pdog··on 'Big Short' investor predicts Tesla stock will collapse like the housing bubble
Generally speaking, you don't initiate a short position with longer than a two- to three-year time horizon. The cost of borrowing the shares, plus the opportunity cost of holding cash for margin maintenance requirements, is too prohibitive.
pdog··on What If You Could Do It All Over?
“Someone once told me the definition of Hell: The last day you have on earth, the person you became will meet the person you could have become.”
pdog··on Why Tesla stock is vastly overpriced
> Are you seriously suggesting that Tesla production will increase by 100x within a decade?

Tesla scaling electric vehicle and battery production by 60% CAGR for a decade doesn't seem too ridiculous when you put it that way. And that doesn't factor in new products. Look at Apple in 2007.

pdog··on Why Tesla stock is vastly overpriced
"Don't tell me what you think, tell me what you have in your portfolio." Nassim Nicholas Taleb, Skin in the Game

If you're convinced Tesla is vastly overpriced, you should prove it by shorting the stock or buying put options.

Betting against Elon Musk has been a terrible move up until now, but if you really think the stock is overvalued, you're probably better off simply not owning it. If you're still concerned about its inclusion in the S&P 500, you can buy an S&P 500 index fund and short just enough Tesla stock to exclude it, or buy a different index fund that doesn't include it.

pdog··on Show HN: After 10 years my side project has hit $8k/mo in revenue
My friend is a SaaS pricing expert. She normally charges upwards of $578 USD per hour for her consulting services, but she was happy to take a look at your site for free.

Here are some of her recommendations:

* Lite should be called Free and it should be lower on the Pricing page compared to the paid plans.

* Paid plans should segment customers by value.

* Premium and Pro plans can be combined into one Premium plan for $29 per month minimum.

* Enterprise pricing should be on request ("Call Us") or $249 per month minimum.

* You should be price testing via list offers.

I had no idea what "disposable terracotta cups" were, but they're pretty interesting:

pdog··on How to take meeting notes
This works well for daily journaling too.
pdog··on Creator Mansions, Shitposts and Chief Meme Officers
What's with all the emojis?

I tried reading the article, but I gave up after twenty or so emojis. They're attention-grabbing for no reason.

There's something seriously off-putting about so many emojis in an article written by an adult. It's like the author doesn't even care about his own writing.

pdog··on S&P 500 Return Attribution: Its 1% economy
Stock market returns have always been about a small handful of big winners. It's one of the reasons why indexing usually outperforms stock picking.

The median stock actually performs worse than short-term treasury bills. In other words, cash is a better investment than most companies.

pdog··on The Age of Mass Surveillance Will Not Last Forever
The article doesn't really explain why mass surveillance or surveillance capitalism has to end.

In fact, if the exemplary tools of resistance are lasers and traffic cones, it sounds like the system is well on its way to being perfected.

pdog··on U.S. citizens no longer have access to most of the world
Most Americans don't even realize they're trapped in their own country now. You can't leave even if you want to.
pdog··on What's the point of a Covid-19 test that takes 19 days for results?
That's my point. The Spanish flu killed 750,000 in the United States at a time when the population was around 100 million. It was certainly a massive crisis.

What was the reporting like and how has it changed?

pdog··on What's the point of a Covid-19 test that takes 19 days for results?
Did this pervasive level of criticism, animosity, and negativity exist a hundred years ago during the last serious pandemic? Every week there's some new crisis.

It feels like the entire media is always trying to highlight the next systemic failure. "This is wrong." "This failed." "We don't have enough ventilators." "New York cases are surging." "California cases are surging." "We don't have enough PPE." "We don't have hand sanitizer." "We don't have masks." "We don't have enough tests."

Are things actually this consistently bad, or does the media magnify the negative and ignore the positive developments (of which there are plenty)?

It's like the difference between acute inflammation (which is good for the body when it's fighting an infection) and chronic inflammation (which causes a lot of problems).

pdog··on Bloomberg chief editor: We publish too many mediocre and long enterprise stories
A lot of good writing advice in this memo:

The key person to think about is the reader.

People generally read only one screen and SELDOM read more than two screens. (A screen typically is around 300 words.)

A long story on a complicated topic can save readers time if it replaces the need to read a lot of short ones.

Readers either want to have a quick piece of information or something that justifies the longer read.

A good rule of thumb is that stories should either be shorter than 400 words or longer than 900.

Taking 700 words or 800 words to make a single point will just annoy readers.

Keep it short. Think of the reader.

Don't worry. Fiddling with your one free parameter to make your model look good is as quintessential to statistics as Student's t-distribution.
pdog··on Why do so few people major in computer science? (2017)
Even in more mundane settings, the status of computer scientists is usually negative. For example, if a random acquaintance asks what you do, you'd be better off telling them you're homeless or unemployed than to admit you're a software engineer.
pdog··on Ask HN: What’s a big trend we should all be following?
The golden age of web app development was 2012-2013.

The state of the art in the browser was jQuery and ES5. CoffeeScript was mature and stable. The Express framework and Node.js 0.8 were perfect for server-side JavaScript.

It was blazing fast, unopinionated, and minimal. It's too bad it didn't last.

pdog··on Apple rejects Hey for second time, threatens removal from App Store
If Apple charges a 30% fee, the total price would have to be $141.43 to get back $99 for the subscription.
pdog··on Why Sleep Deprivation Kills
I thought maybe you were being overly critical and the writing wouldn't be so bad... then I read halfway through this sentence:

On a cold morning this winter, Rogulja leaned over a tablet in her office, her close-cropped dark hair framing a face of elfin intensity...

pdog··on Three authors retract study on hydroxychloroquine and chloroquine
There a huge battle going on between hydroxychloroquine (the Republican therapy of choice when combined with a zinc supplement) and remdesivir (the antiviral drug by Gilead that's preferred by anti-Trump liberals).

To answer your question, there can be an economic interest in claiming a competitor treatment (which is generic and manufactured cheaply) doesn't work.

Can you update the title? The vital parts are being recycled (battery, motor).
pdog··on Caffeine: A vitamin-like nutrient, or adaptogen
A lot of nutrients (e.g., caffeine, vitamin D3, the fiber in raw carrots) are the closest thing we have to a "free lunch" because the evolutionary pressures that limited access to these nutrients are gone.

Our brains used to compete for scarce calories and nutrition, but now we can vastly increase these things with little to no downside.

There is no scientific distinction between food, drugs, and nutrients. They're all molecules. All that matters is the dosage.
