seles··on Incentives are for losers
Agreed, it is a flaw of the article, but I think their point is still correct (that we should all stand for something beyond what is easiest for us and not use incentives as a free pass for everything).
seles··on Incentives are for losers
It is true that privileged people can sacrifice more to do the right thing simply because they have much more than they need to survive. But most people of all levels of privilege can do better, and it's not a competition where you are only a success if you do the most good. Good is good even in small quantities regardless of if you ever have a statue made after you.

seles··on Tesla worker killed in fiery crash may be first 'Full Self-Driving' fatality
The issue is that it isn't safer, seemingly under any conditions. If it had lower accident rate per mile, that the stat for humans includes adverse conditions while the stat for tesla only includes ideal conditions. Presumably humans are safer than their average on highways...

Also the original quote is flat out wrong as they are deemed 10x more likely to crash according to this: https://prospect.org/infrastructure/transportation/2023-06-1...

seles··on Tesla worker killed in fiery crash may be first 'Full Self-Driving' fatality
One thing I hate about Musk saying things like "They have fewer accidents than people" is that it is only able to be engaged in the easiest of scenarios. So per mile, self driving on the easiest roads barely has less accidents than a human in adverse conditions?

That doesn't seem to actually be better than people yet.

seles··on Tail recursion, but modulo cons
Cool, I had heard of defunctionalizing CPS before but never dared to try it.

I tried to follow along defunctionalizing map, but it is a bit different since it has a return value, whereas in the video it is a void. What I ended up with was equivalent to building a list and then reversing it. So it did infact work (all functions were tail callable). This was mentioned in the article as inferior to the author's final product though. So I think it is a bit different to a special case of CPS defunctionalization optimization.

Although there may have been other ways to deal with the return value in continuations...

seles··on Tail recursion, but modulo cons
This kind of feels like using continuations, here is a Haskell demo of the concept:

    myMap = myMapHelper id
    
    myMapHelper cont f [] = cont []
    myMapHelper cont f (x:xs) = myMapHelper (cont . (f x :)) f xs
Of course this actually makes things slower in Haskell, either due to the growing continuation or existing optimizations in Haskell
seles··on What Every Programmer Absolutely, Positively Needs To Know About Encodings (2011)
According to the article, PHP can handle other encodings by just treating sequences of strings as byte sequences and not caring what the encoding is. There example:

$string = "漢字";

But if you are using say UTF-8 and one of those Chinese characters has one of its bytes have a value of 34 (the ascii value of "), then wouldn't the string terminate prematurely?

Edit: to answer my own question, quote from wikipedia: ASCII bytes do not occur when encoding non-ASCII code points into UTF-8

seles··on YouTube's Fake Animal Rescue Ring [video]
Meat industry cruelty does no make this cruelty ok, nor does this cruelty make the meat industry cruelty ok.

Does anyone know the name for this type of fallacy? Not False Dichotomy but similar?

I was under the impression it was already being flagged and ignored. Could you explain how that would help?

BTW I cannot view that link... "This site can’t be reached" :)

seles··on YouTube's Fake Animal Rescue Ring [video]
These channels are immoral and against YT's TOS. YT should take them down, but they haven't (yet).

Something I could do about it is personally is stop using YT until they do. I've seen other instances of the negatives of YT that are making me think this is what it must come to (i.e. https://news.ycombinator.com/item?id=24571038).

The ironic thing is that I'm tempted not to ban YT because there's so much content that I like (pbs spacetime, veritasium, etc). However this type of reasoning is how atrocities in the past have been allowed to happen. Essentially youtube is Google's real monopoly and this is just another example of the problem of monopolies.

So I'm going to block myself from youtube (since habit is too hard to break, I'll do it by adding these lines to /etc/hosts)

127.0.0.1 youtube.com

127.0.0.1 www.youtube.com

Could someone please post here when these channels are deleted?

seles··on Mathematicians should stop naming things after each other
There's an equally annoying problem in software engineering at large corporations (aka Google), where hundreds of services you need to know about are named with some cute name that gives you no idea what the thing actually is.
seles··on America is giving up on the pandemic?
Link to source? Current data on cdc is 1,920,904 cases and 109,901 deaths which is 5.7% (and it doesn't appear to be changing much). That's about 20 times higher than your figure of 0.3%.
seles··on Tracking Coronavirus by Smell Test
True, but it didn't really start to spike until around the march 22-28 bin and there are articles about this around that time, for example a quick google serach finds https://www.health.com/condition/infectious-diseases/coronav... from March 23

So this could easily be explained by people googling about the theory itself.

seles··on Open letter from Italy to the international scientific community
Lockdown is not a long term solution though. This virus isn't going to disappear anytime soon. It might be good for countries that are getting out of control, but for places where it isn't a problem yet it just delays when it his.

Places without a problem yet should take reasonable sustainable precautions to flatten the curve instead. (https://www.flattenthecurve.com/)

seles··on Petition to drop charges against Kiera Wilmot
I would guess that what she was doing was causing the bottle to pop by doing a chemical reaction inside it that creates lots of gas as a by product of the chemical reaction, enough to cause a significant increase in pressure until the bottle pops.

This is actually something that kids did when I was in high school 10+ years ago (although never at school or during school hours). I don't think it is a good thing for kids to be doing, but I do think authorities are over reacting (pun intended), it is not a real explosion or bomb, just a bottle popping. However I do think someone could get hurt if they were right next to it when it pops.

seles··on Hacking strength: Gaining muscle with least resistance
I agree, it is the biggest downfall of Starting Strength. It would be much more accessible if they just had a well organized library of video instructions for all the lifts the program uses. I find it hard to learn from a book...
seles··on Hacking strength: Gaining muscle with least resistance
I started with stronglifts 5x5, but switched to Mark Rippetoe's Starting Strength.

Starting Strength is a little harder to get into because it is based off of a paid book instead of a free pdf. But it is a better program in my opinion. Stronglifts is basically a ripoff of it but with better search engine optimization, hence its popularity.

Differences:

-Stronglifts starts with minimal weight. Starting Strength starts with weight that is hard. I think it is advantageous to do lower weight if you need to figure out form, but if you can get proper instruction there is no reason to start so low, you are just wasting time.

-Starting strength does 3x5 instead of 5x5. 5x5 is too many if the weight is truly difficult (Stronglift agrees and goes down to 3x5 when you get failures)

-Stronglifts has a bunch of instructions and rules to follow, but there really is no explanation as to why, for form or the program. Starting Strength's book is extremely thorough (almost too verbose).

-Starting Strength does power cleans instead of barbell row. Power cleans are essential because they develop speed, while all other exercises in both programs only develop strength. Work the lats with Chin-ups.

-The author of Starting Strength seems more credible since the programs are so similar yet his came earlier, he has been around a long time coaching, and has lift much higher weights than the author of Stronglifts).

Both programs will be a million times better than nothing, but I think if you are serious about getting strong Starting Strength will serve you better.

seles··on Evasi0n iOS 6.x jailbreak
It worked for me, but now I am getting error "HTTP/1.1 500 Internal Server Error" in cydia

It looks like this also happened to people alot when the jailbreak for iOS 5 first appeared, so I am pretty sure cydia is just getting flooded with traffic from hoards of newly jailbroken users.

seles··on PressureNet collects 120,000 atmosphere data points per day from Android phones
I don't think ambient temperature and humidity sensors would work very well because people usually aren't outside and when they are, phone is usually in pocket.

I love this idea too though. I'm guessing pressure is one of the least effected by being inside or in a pocket, while still being highly useful for weather prediction.

Wow, is indeed very good. Thank you. Where do you find out about gestures like this? I can't help but wonder what other gestures are secretly lurking.
seles··on [dead]
I don't even like pinch to zoom. It is hard/impossible to do when using the phone one handed. It is also annoying in apps like google's new maps for iOS because it is hard to not also rotate the map, which is hardly ever the desired outcome.
seles··on The Gift of Death
I just had a realization on why people may consume like this.

People spend so much time working hard instead of doing what they really want to, because it is expected of them. By consuming they feel their work was worth it and it is the only way they can avoid the dread that they have wasted their lives not following their dreams?

seles··on All Rational Approximations of Pi Are Useless
Setting MaxExtraPrecision to "to use as much automation as it needs to resolve numerical values" looks very interesting. It seems like it is being lazy, because the amount of precision needed isn't known until after the result is used (in this case the function that counts number of correct digits).

Any idea how this is implemented in mathematica?
