tfha··on What If Planet 9 Is a Primordial Black Hole?
~11 km/s to escape the sun, ~30 km/s to fall into it. Escaping is easier.
tfha··on Why Go and Not Rust?
Cgo is a very well supported paradigm and many projects use cgo copiously.
tfha··on Bring Back the SE
I have a pixel, it's 5 inches and it feels absolutely enormous compared to the SE. I don't like it at all and yet it's classified as "small" today.

Not a fan at all, it's just too big for me. I'm 6'1"

tfha··on WeWork Parent Weighs Slashing Its Valuation in Half
Some indexes have filters that prevent really awful companies from being included. For example, I don't think Snapchat was allowed into the S&P 500 because the stock was so crappy.
tfha··on Human speech may have a universal transmission rate: 39 bits per second
If you close your eyes listening comprehension goes way up. I top out around 2x if I have to look but with my eyes closed I can get full comprehension at 3x+

If it's a technical talk or something I'll still pause often too reflect on what was said, but I can hear full sentences just fine at >3x with my eyes closed.

tfha··on The Fry’s Era
Once online shopping with 2 hour delivery becomes more ubiquitous it's going the be harder to be a brick and mortar store

tfha··on Banned from Google Ads for Using Apple Card
Yeah the real issue is the choice. If there were 5 or 10 reasonable alternatives, this kind of thing wouldn't bother me at all. But if the options are "obey Google or fail", suddenly it's a big problem.
tfha··on Uber proposes policy that would pay drivers a minimum wage of $21 per hour
I wouldn't assume it comes from an ethical origin. It's more about killing competition. As soon as the competition is dead they'll be talking about how non-viable $21/hr is.

Also, a high minimum wage for drivers really bumps the value of their self driving car arm.

tfha··on I Took a Pay Cut for a More Meaningful Job
There utility of disposable income is perhaps not linear. But I can tell you I enjoyed my second raise a lot more than my first. My first raise gave me just enough to start saving money over time, no room for quality of life improvements. My second raise is what allowed me to start spending money to enjoy myself.
tfha··on Researcher banned on Valve's bug bounty program publishes second Steam 0-day
At some point this is less of a steam issue and more of a Windows issue. An OS shouldn't allow applications to compromise eachother.

Steam should maybe be liable if they are actively thwarting disclosure that would protect users but that's a tough thing to establish legally.

tfha··on Researcher banned on Valve's bug bounty program publishes second Steam 0-day
Eh that one is on you I think. How long did you wait? If we have 5 researchers report the same vulnerability in 30 days we're going to count it as duplicate and still expect to have a full 60-90 days from the first report to deploy a fix.
tfha··on The League of Entropy Is Making Randomness Truly Random
No need for commit reveal, just do a relative offset for picking the rng. So after you place a bet, 6 blocks later is the block that decides if you succeed or fail.

You can use simple techniques like this to make most use cases secure.

tfha··on The League of Entropy Is Making Randomness Truly Random
You can solve this problem by picking a specific block height, and not confirming the result until it has at least 6 confirmations.
tfha··on The League of Entropy Is Making Randomness Truly Random
A block proposer has a small probability of being able to re-roll the random number a single time, and an exponentially lower probability of getting a second or third chance. And each attempted manipulation costs a lot of money.

Can easily put secure bounds on this and use it for most applications.

tfha··on The League of Entropy Is Making Randomness Truly Random
Why? Please provide a meaningful reason why Bitcoin cannot be used for secure randomness.
tfha··on The League of Entropy Is Making Randomness Truly Random
The effect of this can be minimized by pre-comitting to which block will be used for entropy. Then antpool has a 10% chance of mining the relevant block, a (.1*.5=0.05) 5% chance of mining an unwanted bit and discarding it, and then from there the chance that another unwanted bit is found will be close to 50%.

All considered that means antpool has a 2.5-3% chance of flipping an wanted result into a wanted result. At $125,000 per block, that's $4 million of cost per bit manipulated favorably, getting exponentially worse as you need to manipulate more bits.

tfha··on The League of Entropy Is Making Randomness Truly Random
Doesn't the Bitcoin blockchain serve as a strong, independent, difficult to manipulate source of entropy that gets published every 10 minutes on average?

Why not just use that?

tfha··on WeWTF
Absolutely not. Political correctness is a term for completely suffocating certain lines of thought such as stereotyping and certain methods for expressing outrage. PC culture is highly alienating to many Americans and is one of the reasons that Trump was so successful in 2016.
tfha··on WeWTF
We've all become too PC and the stains of that culture are bursting out the sides in unexpected and colorful ways. It's oppressive to be PC and we haven't acknowledged that side of it well enough. (Oppressive to the person constantly censoring themselves in the name of PC)
tfha··on The most frequent 777 characters give 90% coverage of Kanji in the wild
Not enough information. For example, in English some of the least common characters are also generally not important for conveying information.

Your argument only holds if Kanji was designed to be optimal in compressing information, which is of course not how Kanji came to be.

That doesn't mean you are wrong, but your argument is invalid.

tfha··on Amazon offered ‘Amazon’s Choice’ to vendors who bought ads and lowered prices
Wasn't obvious to me. I had assumed editorial oversight.
tfha··on Google Chrome Incognito Mode Can Still Be Detected
Just don't use sites that dont respect your privacy. If it doesn't like you blocking cookies, walk away.
tfha··on US Navy will replace touchscreen with mechanical controls on its destroyers
The emergency brake. I really need that to be a mechanical lever and not an electrical one. If something is going wrong on the road I need a backup brake that takes me under a second to activate while in a state of panic with my eyes glued to the road and it had better be functional.
tfha··on China successfully launches its largest reusable rocket
That's something. SpaceX started around that scale too, remember? 5 years from now they might actually be getting payloads to space.
tfha··on Jeffrey Epstein: Financier 'found dead in cell' in New York
Wasn't he on 24/7 camera surveillance?
tfha··on Jeffrey Epstein: Financier 'found dead in cell' in New York
And he was under 24/7 camera surveillance. If it was a clean suicide there should be video evidence.
tfha··on Jeffrey Epstein: Financier 'found dead in cell' in New York
Epstein was supposed to be under 24/7 camera surveillance. But they are saying there was a camera malfunction.

Dunno man it really doesn't add up to a suicide.

tfha··on Home Chip Fab
That would be amazing!
tfha··on America’s social-media addiction is getting worse
The average person is fighting teams of phds at Facebook, Google, and Amazon that are finding more and more ways to capture an maintain your interest, and to ensure that you can't put your phone down for more than a few minutes.

Honestly I think a comparison to cigarettes is fair. Between the anti-patterns, the machine learning, the A/B testing, and the behavioral engineering, modern phone apps are more addicting than niccotine, and it's no more a person's fault for not being able to control themselves than it is for a smoker craving another cig.

The problem cuts a lot deeper than people having no self control. They are actively fighting intelligent, well resourced adversaries who have a long term goal of getting you hooked.
