Not really; there's a few substantial differences between shared objects with SONAMEs and link-time vs run-time file system names and LD_LIBRARY_PATH and /etc/ld.so.conf vs DLLs and searching PATH (starting with "."

Right - and so you get same situation that you have in C++-land (if I'm understanding you correctly) where compiling arbitrary rust programs with the distro compiler level may benefit you if you want to depend on the system-provided ru

The biggest reason (for me anyway) to restrict which gcc I use (and stick to the system-provided one) is so I don't need to distribute libstdc++ and libgcc_s with my program. The RedHat devtoolset was a nice solution to this (use a new

I'm in a similar situation. I am cautiously optimistic that "mrustc" can help in this area. Compiling rust to C++ seems like the right direction for the more esoteric operating systems and platforms.

In many cases the question mark operator can propagate errors for you. It is both explicit and non-verbose.

If you can deliver responses 10x faster than required, you can scale with 10x fewer resources (or at least presumably some factor of fewer resources) and still stay within the user requirements. I'd say that's a nice advantage.

It isn't wrong if that was the order the bytes were packed on the sending side.

The beauty of lisp-like languages isn't in the visual appearance of the code as text (the parenthesis and layout), but in the structure of the code as trees, the uniformity, and the homoiconicity.

This is cool. I never actually realized that magic squares exhausted all of the sums to 15; in other words, there is no triplet which sums to 15 and is not already a row, column, or diagonal. No false positives, so to speak. I wonder if thi

Some of the products look the same... Is this the same company or something?

Is this always true? If the shared library you linked to uses symbol versions and the bug fix requires a new version of a symbol, the application has to be relinked anyway. Same as static linking, except now it is not obvious you need to re

The solution to this seems trivial, no? Don't allow cases to be brought in courts if the identity of the plaintiff can't be verified?

I mean in python, one can ask a function what it was originally defined as. Sounds like in F# one can not, so that's why there's a difference in python between "var x = lambda..." and "def y(): ..."; the latter

In F#, can you ask a function object what its original name was? If so, what is the original name of "test1" and "test2" in your example? That's what python is doing and why the two are different. (I don't thin

Many of the suggested alternatives to lambdas in the article are non-imperative though... they just don't use 'lambda'.

For me personally, smaller file sizes and less verbosity both improve readability.

Why are the only two options "do nothing" and "throw them in prison"? Shouldn't there be a middle ground here?

Do you let the people who have "no idea what they are doing" write functions too? Put code into production? You pay them right? You train them? Why not teach them about macros and have code reviews on things they submit, just like

If you really know c++, then you know it is not easy to write safe code. It is easier than it used to be, for sure, but not yet easy.

Why do we need a physical key though? Why don't browsers communicate the url to the password/totp app, and the app only respond or allow fill-ins for matching domains?
