XPath does general data processing not just selection E.g. when you have a list of numbers on the website, XPath can calculate the sum or the maximum of the numbers Or you have a list of names "Last name, First name", then you can

These benchmark things reminds me of an anecdote I saw today in the D group: >Back in the 80's (!) computer magazines regularly ran C compiler benchmark results. (At one time I counted 30 C compilers available for the PC.) >I too

Actually, Pascal has slices They are just so obscure, I forgot about them and no one uses them. No users, no problems They are not part of the normal type system. You cannot declare a variable of a type slice. Nor a field. But when a parame

In Pascal, there are no slices No slices, no problems If you need to work with a part of a string, you can make two ordinary integer variables for offset and length

And you could not write 1e300 since it is not exact You need to write 10000000000000000525047602552044202487044685811081591549158541155118024579889081957863713750804478640437044438328838781769425232353604305756447921847867069828483872009265

If you want to have that in production, you should run a test suite on it. There is a popular test suite by nst. Although some go too far. I just had to write my own JSON parser (resp. rewrite one), because the parser I was using did not pa

I use another regex library that does that and do not like it at all Something like \w makes the regex complexity explode. It spends more time building the regex than actually matching it.

Delphi/Pascal has 2-layered constructors. There is a virtual class method to allocate memory and a so called constructor that initializes fields that should be zero. The user of a class, only calls the constructor. The constructor then

At first I read the title as Plan 9 That would explain why it is not more popular. If you install your software in a black hole, you cannot get any computed data from it out again.

They are making new languages far too often It started with XPath, then came XPath 2, then XQuery 1, then XPath 3.0 and XQuery 3.0, and then XPath 3.1 and XQuery 3.1. Six new languages each more expressive than previous one. That is why it

On the contrary. If you do a PhD, you can get paid by the university and build some net worth. And people are impressed when you say you have a PhD, but do not care when you tell them about a graveyard project
