Yes, truly the only thing holding C++ back has been lack of features. Have a link: http://yosefk.com/c++fqa/

from http://dl.rust-lang.org/doc/tutorial.html "7.3 What to be aware of Rust has three "realms" in which objects can be allocated: the stack, the local heap, and the exchange heap. These realms have corresponding pointer types: the borrow

Go is not a conservative language. A conservative language would be something like D, which is mostly a clone of C++ with a few extra features tossed in. Go is a highly opinionated language with at least three big new ideas: * goroutines

Rust has three different ways of allocating memory. And you can't pass things allocated one way to functions that expect something allocated the other way. A Python replacement, this ain't. More like C++ on quaaludes.

Needing lots of expensive invariants is almost "invariably" (see what I did there?) a code smell. You often see big, complex classes with 10 different booleans and a ton of assertion crap, when what is really needed is to refactor the clas

Let's say that I fire someone, and I absolutely can't afford a severance package, leaving him out in the cold. Let's also say that the following are the options: Um, you think that people are forced to "butcher [their] entire family in a

So far we've established that: 1. you run with assertions always on in production, 2. you have encountered errors caught by the always-on assertions in production (it may be "seldom," but then all errors are seldom, hopefully.) How does thi

I think you are confusing together a few different things. A sanity check that is always on is not an assertion (at least by the usual sense of the word). Nobody is against sanity checks, just like nobody is against motherhood and apple p

Thanks for the correction. Back when I first used go, they did different things. The change makes sense, I think-- we already have select for nonblocking I/O.

Annoyance at the lack of assertions In 10 years in the industry, building distributed systems and server-side software, I've never seen assertions work out well. In two of the jobs I was at, we ended up making the assertions always-on, e

By the way, it's not true that Golang strings are always UTF-8. Golang source code is always UTF-8, but strings can contain arbitrary bytes. Trying to force all strings to be UTF-8 can lead to fiascos in the real world, where legacy enc

Yeah, the use requirement is annoying. It would really be nice if there were a way to make that check optional. As far as closures capturing references-- if closures captured by value rather than by reference, how would maps and slices be

Yeah, it's arbitrary that val, ok := <- ch does something different than val := <- ch, but any other convention for differentiating blocking from nonblocking would be just as arbitrary. I think it's something I would get used to af

Sorry in advance that this is so negative, but it reflects my honest feelings, as well as some experience. The big problem with Python was always predicting what any given piece of code would actually do. Considering the lack of static typ

Um, UTF-8, a valid unicode encoding, handles strings with a null terminator just fine. Those who throw stones, should not live in glass houses. Proper unicode support would include things like normalizing strings (Unicode has 4 different n

Web.go is sort of the Golang equivalent of Sinatra or Camping, not really of Ruby on Rails. What you're looking for is Revel. http://robfig.github.com/revel/

If GPS is unavailable, it reverts to using atomic clocks. As those gradually drift out of sync, the system slows down until the problem is fixed. NTP is not used, at least in Spanner.

What a disgusting response. "Someone else may or may not have done something worse at some point, so anything I do is ok." By the way, you may want to Google for Scott Thompson. He was a CEO of Yahoo, until they found out that he had lied

Um, not using a virtual machine doesn't mean using unmanaged code. Even Java can be compiled to native x86 machine code using GCJ. Golang, for example, does not use a VM, but it is a managed language.
