Differences between Java 8 Date Time API (java.time) and Joda-Time
...
Common features
a) Both libraries use immutable types. Joda-Time also offers additional mutable types like MutableDateTime.

Webfonts or Locally loaded fonts?
...ust me). The JS file loaded by the script (http://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js) is larger than the @font-face declaration, and just looks like a lot more work. And I don't believe loading the actual font itself (the WOFF or TTF) is blocking, so it shouldn't delay things too muc...
How to generate a random string of a fixed length in Go?
...te slice as a "bit stream" for example, for which we have a nice 3rd party lib: github.com/icza/bitio (disclosure: I'm the author).
But Benchmark code still shows we're not winning. Why is it so?
The answer to the last question is because rand.Read() uses a loop and keeps calling Source.Int63() un...
Extracting bits with a single multiplication
...his in terms of something that a theorem prover can understand, namely SMT-LIB 2 input:
(set-logic BV)
(declare-const mask (_ BitVec 64))
(declare-const multiplicand (_ BitVec 64))
(assert
(forall ((x (_ BitVec 64)))
(let ((y (bvmul (bvand mask x) multiplicand)))
(and

What is the maven-shade-plugin used for, and why would you want to relocate Java packages?
...se cases which involve package renaming.
For example, I am developing Foo library, which depends on a specific version (e.g. 1.0) of Bar library. Assuming I cannot make use of other version of Bar lib (because API change, or other technical issues, etc). If I simply declare Bar:1.0 as Foo's depen...

How would you implement an LRU cache in Java?
...u need a simple LRU map.
I welcome feedback, except the why don't you use library a, b, or c.
The reason I don't always use a library is because I don't always want every war file to be 80MB, and I write libraries so I tend to make the libs plug-able with a good enough solution in place and someone...
What are the differences between Generics in C# and Java… and Templates in C++? [closed]
...enerics, and having it run on old 1.4 or previous JVM's, which microsoft deliberately decided not to bother with.
The downside is the speed hit I mentioned previously, and also because there is no ListOfPerson pseudo-class or anything like that going into the .class files, code that looks at it late...
Android studio: new project vs new module
...ter whole.
For Android, it means one project per app, and one module per library and per test app.
There are multiple issues if you try to build multiple apps within the same project. It's possible, but if you try (like I did), you will see that almost everything is designed to work with a single...
