Not true. Saturn V's lift to LEO was 120-140 tonnes ( https://en.wikipedia.org/wiki/Saturn_V ) while SpaceX claims Starship's is "over" 100 tonnes ( https://www.spacex.com/media/st

In particular, all Saturn V engines were completely hand-built and the process was not documented. A lot of very fine craftsmanship went into that that we can't replicate today.

It is not an absurd claim. The statistics are available to everybody. Israel implemented vaccinations efficiently and very quickly their infection rates dropped close to zero. I live in Poland and same thing happened here. Now the infection

For you young people, there is one language which is called "executable line noise". This is valid Perl code syntactically, except Perl complains of invalid or incompatible regexp modifiers. So, if you chose the characters careful

I think you are overreacting. Even if you were right (which I don't agree is the case) you need to understand the examples are not there to teach you good API design. The Pet Store is a Hello World of APIs and the point of this example

Starlink is supposed to operate 30k satellites, and it currently has something around 1,5k (correct me if I am wrong). What this means is we can expect that in future obstructions will be much less of a problem, because there will be much b

General availability of food as a driver of obesity is a false premise IMO. It does not explain a lot of countries where food had been available for well over half a century in any quantity you wanted and yet people don't have problem

As much as I like to produce correct code in the first place, I think it is very relative and depends on the project. There are projects where nobody cares much about bugs in production and it would cost a lot to make sure no bugs enter pro

My mental model of value of an idea is that it is one of multipliers . There are many different factors that affect end value: execution, value to others, luck, timing, etc. The end value is all those factors multiplied. Even if your idea

Well, not exactly. What it really means is that the execution time does not depend on the size of input (n). What it does not say is how much time it takes to execute, whether it is exactly same amount of time every time or whether there ex

If your data structure is immutable, then an array is always faster than a linked list.

What is not applicable? If one person says a linked list is faster than an array list but the opposite is true, then why do you claim it is not applicable? Isn't it exactly the point of the article, that sometime you need to say what t

Unfortunately, you are wrong. Arrays used as backing for lists are faster than linked list in almost all cases, assuming they are implemented correctly (as is the case in Java, which I bring as an example). Linked lists have a lot of huge d

Just about the same happens every time I am asked about why do we need microservices or TDD. Because if I went to say that most projects need neither I would probably never get any job.
