Why is it so hard lol? I have the Bank of America Rewards card for 25+ years. 2.62% cashback on everything, 3.5% on dining/travel. Maybe there are better ones out there but this is good. I have auto-pay setup so I don't have to worry. I have not spent a second of my time optimizing anything in last 15 years

10-15 years ago HN was the place where everyone showed off their new shiny toys and people would jump over themselves to try some new framework or db or tool. Now, so much negative sentiment about AI coding. I bet if LLMs came 15 years ago, HN would be brimming with excitement. What happened?

I love math but the symbology and notations get in my way. 2 ideas:

1. Can we reinvent notation and symbology? No superscripts or subscripts or greek letters and weird symbols? Just functions with input and output? Verifiable by type systems AND human readable

2. Also, make the symbology hyperlinked i.e. if it uses a theorem or axiom that's not on the paper - hyperlink to its proof and so on..

This would be amazing

Do you need to know internals of a database or just use them as a tool. If you hit some bottleneck, you go deep.

Cool! I make this as a hobby project: https://framed.news/

Would be cool to have a color option too

My favorite conspiracy theory:

After Tiananmen, the CCP planned many contingents next time something similar happened.

Cue, the [2019 Hong Kong Democracy Protests][1]. The MSS releases Covid19 at the peak of the protests (actually they do pick Wuhan so they can use lab leak as a plausibility if needed) in Sep 2019 and later they use the lockdown laws to completely clamp down the protests.

Most likely he realized once the authorities have his name - he can't run forever.

That being said - some obvious stuff he could have done like grow a beard and shave it after and fly out of the country to somewhere cheap like Thailand with $10k

Cool! Btw, I make this: https://framed.news/ framed e-ink news display

Why not respond with both X and Y? e.g. for the last 3 character thing, here would be an appropriate response:

To get the last 3 characters, do `echo ${foo: -3}`. Are you trying to get the file extension though? What if the extension is not 3 characters e.g. `foo.jpeg`? You then want to do `${foo##*.}`

Teslas have creep off by default.

Honestly, probably worth it just to not have to pay for hosting.

When I first read Monty Hall problem, I actually thought it was blindingly obvious to switch. The fact the presenter had 2 doors to chose from and the one he opens is a goat _should_ increase the chance of the other one being not(goat) right?

Is there a database of leaked passwords somewhere? I would simply enforce that your password is not in the leaks? Probably would capture the most common 100k passwords anyway this way?

My quick and dirty tl;dr: https://gist.github.com/pathikrit/a7845f72645159646fdb632bc3...

Let C<A> be a higher-kinded type e.g. in List<Animal>, List is C and Animal is A.

Let S be a subtype of T e.g. in class Cat extends Animal, Cat is S and Animal is T

If C<S> is a subtype of C<T>, then C is covaraint on T e.g. List<Cat> is a subtype of List<Animal>

If C<T> is a subtype of C<S>, then C is contravariant on T e.g. Predicate<Animal> is a subtype of Predicate<Cat>

If neither C<T> and nor C<S> are subtypes of the other, thenC is invariant on T

Honest question: If I want the diversity of a Ikea catalogue with higher price and quality, where should I go?

Or just pay $100/yr to back it up to Dropbox (or even cheaper AWS Glacier)?

Some buffalo jumps were used for thousands of years and had CRUSHED BONES from millions of animals falling over compressed into walls tens of feet high.
