After array_filter(), how can I reset the keys to go in numerical order starting at 0
...s an array with mixed values in it that will expose the trouble:
$array=['foo',NULL,'bar',0,false,null,'0',''];
Null values will be removed regardless of uppercase/lowercase.
But look at what remains in the array when we use array_values() & array_filter():
array_values(array_filter($array)...
Scala equivalent of Java java.lang.Class Object
...Nov. 2011, two years later, fixed.
In 2.9.1, getClass now does:
scala> "foo".getClass
res0: java.lang.Class[_ <: java.lang.String] = class java.lang.String
)
Back in 2009:
It would be useful if Scala were to treat the return from getClass() as a java.lang.Class[T] forSome { val T : C...

sqlalchemy IS NOT NULL select
...
In case anyone else is wondering, you can use is_ to generate foo IS NULL:
>>> from sqlalchemy.sql import column
>>> print column('foo').is_(None)
foo IS NULL
>>> print column('foo').isnot(None)
foo IS NOT NULL

Passing an array as a function parameter in JavaScript
...
Function arguments may also be Arrays:
function foo([a,b,c], d){
console.log(a,b,c,d);
}
foo([1,2,3], 4)
of-course one can also use spread:
function foo(a, b, c, d){
console.log(a, b, c, d);
}
foo(...[1, 2, 3], 4)
Python Logging (function name, file name, line number) using a single file
...you is the string formatting using a dict as the RHS of the % operator. "%(foo)s" % bar will be replaced by whatever the value of bar["foo"] is.
Finally, you can use some introspection tricks, similar to those used by pdb that can log more info:

Type converting slices of interfaces

What is the difference between Python's list methods append and extend?
...the end of my_list as a single entry on the list.
>>> my_list
['foo', 'bar']
>>> my_list.append('baz')
>>> my_list
['foo', 'bar', 'baz']
So keep in mind that a list is an object. If you append another list onto a list, the first list will be a single object at the end ...
Modulo operator with negative values [duplicate]
...imizing divide-by-power-of-two operations as shifts. Under the old rules, foo /= 16 could be written as asr [dword foo],4. Under the new rules, the optimal representation requires many more instructions [perhaps mov eax,[foo] / mov ebx,eax, asr eax,31 / lsr eax,28 / add eax,ebx / asr eax,4 / mov [...
