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...

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...

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

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

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?

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?

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%.

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.

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.

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.

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.

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.

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?

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?

That is the R-pentomino which has a life span of 1103 generations, but they were running it on a non infinite grid, so the boundaries probably caused it to die off much sooner.

I don't understand why they are using finite grids (probably efficiency reasons, but with the right data structures you could still implement it fast, see hash life).

The memory hierarchy can never completely flatten. Information takes physical space to store and the speed of light is finite. So the more information, the further things are apart, and the longer access times will take.

That being said this theoretical limit might not be the main bottleneck right now. Parallelism can also bypass this limit since not all information needs to be processed at the same location.
