accountLost··on Two envelopes problem
My take :

let M be the maximum amount of money that a envelope can contain (at worst it can be the total amount of money in the world). You don't know the value of this upper bound M.

Most of the time, you get 2*x or x/2 with 50% chance if you choose the other envelope (which on average is a win)

But when x=M you get M/2 instead of M and therefore you loose M/2 with 100% chance. And when it happens you have lost much more than in the other cases (because exponentiel...)

If you do the math, you can see that what you win for 1 2 4 8 16 ... M/2 is equal to what you loose for M.

And so on average what win from switching is 0.

Not a good heuristic for me as it would make me skip most of the science stuff. For example the Webb space telescope. It certainly won't have any impact of my life.
accountLost··on Don’t point out something wrong immediately
Yes, when possible it is better to give people time to figure out things by themselves. That's how you learn.

The question is why pointing out something wrong would have automatically damaged your relationship with her ?

Everyone can agree that making mistake is natural. Can't people learn not to get upset when being told they made one ?

One way is by exposure in an environment where the feedback is factual and without drama.

accountLost··on Don’t point out something wrong immediately
I can't agree with that. If there is something wrong, it must be dealt with as soon as possible. We engineers must learn to be professional and not let our ego get in the way.

Maybe it is a cultural thing ? I worked once in Germany and thought at first that the error pointing was brutal. But you get used to it and learn not to involve your self esteem. And retrospectively I found it to be a fair and effective work environment.

accountLost··on Hoare’s Rebuttal and Bubble Sort’s Comeback
I remember seeing one occurence of bubblesort in the source code of Crafty chess engine with a comment explaining that this was unexpectingly the fastest sort in that particular case. (It was the ordering of a few moves in the quiesce algorithm I think).
accountLost··on Alder Lake Core i9 processor is faster than the M1 Max
Thank you for your answer. I got instantly buried below the "bad perf per watt" comments and thought nobody would see my question.
accountLost··on Alder Lake Core i9 processor is faster than the M1 Max
This is a 10nm processor, right ? So a 10mn processor can be as fast as a 5mn processor but at more than double the voltage ? Not so bad. What would be the perf of this processor with TSMC 5nm tech ?

That would be the median, not the average (but then it sounds less funny somehow...)
accountLost··on The inventor of the black box was told to drop the idea
First They Ignore You, Then They Laugh at You, Then They Attack You, Then You Win.

"The statement evolved from a large family of sayings that originated in the nineteenth century. In 1918 a closely similar remark emerged in a speech by Nicholas Klein, a union representative. Gandhi discussed stages that a movement passes through in a collection of writings he published in 1921, but his words did not really match the target expression."

accountLost··on Background: how we got the generics we have (2020)
You can't easily create a instance of the generic type in java. for example :

return new T();

is possible in C#, not in java.

accountLost··on Why can't I write code inside my browser?
Even hardworking developers will sometimes don't care about the user experience. For example, Linus could have spent a few hours polishing the git CLI. Instead we have had millions of developer hours wasted in making sens of the CLI inconsistencies...

accountLost··on California plan for wealth tax on anyone who spends 60 days a year in the state
Took me a few minutes to figure it out. chipotle_coyote comment make sens if the tax is 800k. 50m*0.04 = 2m = 800k+600k+600k The tax is not 800k but 80k though. So it should be 80k+960k+960k.

So you could pay the tax, draw out $960K a year (I mean, you can live on that, right? Not a hardship?), and still have another $960K left over.

accountLost··on Ask HN: Was 20% time a good policy for Google's working culture?
Should be 125% though (or is it already obvious for everyone and just me being pedant ?)

Maybe the article means that PHP interprets the OPCodes as opposed to java that uses a JIT compiler that produces machine code for part of the bytecodes. Anyway JIT is coming with PHP8 :

Thanks. I don't expect a great experience but I'd like to see if a eInk reader would be easier on my eyes since I am already 10 hours a day on LCD. The following video gave me the impression that pdf on Kindle Oasis was acceptable...

Does anyone here have some experience using a kindle without account as describe here :

https://www.techjunkie.com/kindle-without-amazon-account/

Or here :

I think after some research that the oasis may be the best value for money reader for my use case (pdf CS books) but I'm not sure about the amazon account and if it is worth the hassle to avoid it.

bigot : a person who is intolerant towards those holding different opinions (google definition). So maybe half of the country is made up of bigots but they are from both side. The other half are those that don't have strong opinions or simply don't care.

Very nice. And that also mean you can keep your notes local and private I guess.
