ViewParam vs @ManagedProperty(value = “#{param.id}”)
...ditional <f:event type="preRenderView" listener="#{bean.init}" /> inside the <f:metadata> to do initialization/preloading based on the set values. Since JSF 2.2 you could use <f:viewAction> for that instead.
Allows for nested <f:converter> and <f:validator> for more fi...
Mongoose, Select a specific field with find
...
The _id field is always present unless you explicitly exclude it. Do so using the - syntax:
exports.someValue = function(req, res, next) {
//query with mongoose
var query = dbSchemas.SomeValue.find({}).select('name -_id')...
Scala list concatenation, ::: vs ++
...ssociative. x ::: y ::: z is parsed as x ::: (y ::: z), which is algorithmically faster than (x ::: y) ::: z (the latter requires O(|x|) more steps).
Type safety
With ::: you can only concatenate two Lists. With ++ you can append any collection to List, which is terrible:
scala> List(1, 2, 3) ...
ssh “permissions are too open” error

Keys need to be only readable by you:

...hem, some of which might even have their roots in MS-DOS DEBUG.EXE (specifically >d, >g, >p, >q, and >t come to mind).
Also worth noting, as it's only two keys to press: Context menu > Clear All invokes the same command and it can be navigated using keyboard. In the immediate wi...
Define make variable at rule execution time
...In this case, it sets the TMP variable to the result of the shell function call.
edit (in response to comments):
To create a unique variable, you could do the following:
out.tar :
$(eval $@_TMP := $(shell mktemp -d))
@echo hi $($@_TMP)/hi.txt
tar -C $($@_TMP) cf $@ .
rm -rf $($@_...

How does zip(*[iter(s)]*n) work in Python?
...e each element is x. *arg unpacks a sequence into arguments for a function call. Therefore you're passing the same iterator 3 times to zip(), and it pulls an item from the iterator each time.
x = iter([1,2,3,4,5,6,7,8,9])
print zip(x, x, x)
