using date(January 1st, 1970) as default standard The Question makes two false assumptions: All time-tracking in computing is done as a count-since-1970. Such tracking is standard. Two Dozen Epochs Time in computing is not always tracked from the beginning of 1970 UTC. While that epoch reference is popular, various computing environments over the decades have … Read more
For C# I don’t believe there’s a specified hard limit. (Section 2.4.2 of the C# 5 spec doesn’t give a limit, for example.) Roslyn v2.2.0.61624 seems to have a limit of 1024 characters; this is way beyond the bounds of readability and even a sensible machine-generated name. For Java, section 3.8 of the spec states: … Read more
See this scala-debate thread for a discussion of what’s going on here. The problem is that Scala’s type inference happens per parameter list, not per parameter. As Josh Suereth notes in that thread, there’s a good reason for the current approach. If Scala had per-parameter type inference, the compiler couldn’t infer an upper bound across … Read more
You may checkout this article. According to the documentation the specific implementation used in .NET is based on Donald E. Knuth’s subtractive random number generator algorithm. For more information, see D. E. Knuth. “The Art of Computer Programming, volume 2: Seminumerical Algorithms”. Addison-Wesley, Reading, MA, second edition, 1981.
There are number of options actually. The 2 that you’ll probably be interested in are -march=c and -march=cpp, which are options to llc. Run: llc -march=c -o code.c code.ll This will convert the LLVM bitcode in code.ll back to C and put it in code.c. Also: llc -march=cpp -o code.cpp code.ll This is different than … Read more
I am an avionics software engineer. I was able to participate in several development projects. The languages I used in those projects are: C, C++, and Real-time Java. C is great. C++ is not so bad but C/C++ require strict coding standards for the safety considerations such as DO-178B. I think Real-time Java is the … Read more
OK, I understood the subtle difference where function overloading is different from multiple-dispatch. Basically, the difference is whether which method to call is chosen at run-time or compile-time. Now, I know everybody’s said this, but without a clear example this sounds VERY obvious, given that C# is statically typed and multiple-dispatch languages (apparently to me, … Read more
I’m glad you’re starting by asking about a specification rather than implementation first. There are a lot of ideas floating around about what FRP is. From the very start in the early 90’s (when I was working in interactive graphics at Sun Microsystems and then Microsoft Research), it has been about two properties (a) denotative … Read more
At launch, Java was the only officially supported programming language for building distributable third-party Android software. Android Native Development Kit (Android NDK) which will allow developers to build Android software components with C and C++. In addition to delivering support for native code, Google is also extending Android to support popular dynamic scripting languages. Earlier … Read more
My assumption has always been that the programming term originated from the following definition of the word “string” (from Merriam-Webster): (1): a series of things arranged in or as if in a line <a string of cars> <a string of names> (2): a sequence of like items (as bits, characters, or words) Since a string … Read more
