AssertContains on strings in jUnit
...
If you add in Hamcrest and JUnit4, you could do:
String x = "foo bar";
Assert.assertThat(x, CoreMatchers.containsString("foo"));
With some static imports, it looks a lot better:
assertThat(x, containsString("foo"));
The static imports needed would be:
import static org.junit.Asse...
How to create an array containing 1…N
...ater loop through.
If this is all you need, can you do this instead?
var foo = new Array(45); // create an empty array with length 45
then when you want to use it... (un-optimized, just for example)
for(var i = 0; i < foo.length; i++){
document.write('Item: ' + (i + 1) + ' of ' + foo.lengt...
What is the point of noreturn?
...atsoever - you know it already. So the following is sound:
(void)5;
(void)foo(17); // whatever foo(17) does
But the assignment below is not:
void raise();
void f(int y) {
int x = y!=0 ? 100/y : raise(); // raise() returns void, so what should x be?
cout << x << endl;
}
[[no...
How do you run a single test/spec file in RSpec?
...or example, if you had a spec like:
1:
2: it "should be awesome" do
3: foo = 3
4: foo.should eq(3)
5: end
6:
Let's say it's saved in spec/models/foo_spec.rb. Then you would run:
rspec spec/models/foo_spec.rb:2
and it would just run that one spec. In fact, that number could be anything f...
In Bash, how to add “Are you sure [Y/n]” to any command or alias?
...f course, this will be set as an alias, like hgpushrepo
Example:
$ echo foo | xargs -p ls -l
ls -l foo?...y
-rw-r--r-- 1 mikelee staff 0 Nov 23 10:38 foo
$ echo foo | xargs -p ls -l
ls -l foo?...n

Proper indentation for Python multiline strings
...
You probably want to line up with the """
def foo():
string = """line one
line two
line three"""
Since the newlines and spaces are included in the string itself, you will have to postprocess it. If you don't want to do that and you have a ...
What is the purpose of “&&” in a shell command?
...g
commands write solely bar to standard output:
$ false && echo foo || echo bar
$ true || echo foo && echo bar
In the first case, the false is a command that exits with the status of 1
$ false
$ echo $?
1
which means echo foo does not run (i.e., shortcircuiting echo foo). T...
Named string formatting in C#
...built-in method for handling this.
Here's one method
string myString = "{foo} is {bar} and {yadi} is {yada}".Inject(o);
Here's another
Status.Text = "{UserName} last logged in at {LastLoginDate}".FormatWith(user);
A third improved method partially based on the two above, from Phil Haack

Double Iteration in List Comprehension
...m counter-intuitive.
Take for example: [str(x) for i in range(3) for x in foo(i)]
Let's decompose it:
def foo(i):
return i, i + 0.5
[str(x)
for i in range(3)
for x in foo(i)
]
# is same as
for i in range(3):
for x in foo(i):
yield str(x)
