getting this error message in ubuntu. in pg_hba.conf file, I tried using 'ident','peer','trust','md5' in different times.but no go. please help.
In my code I have the following:
function foo() {
var bar = [];
... /* Array gets populated here. */
return bar;
}
foo();
If I can be sure that the empty array will always be given, are there any downsides to passing the empty array into the function instead?
function foo(bar) ...
Just a follow-up on question on this - why do you want to turn your iterable into a stream in the first place? Is it because you actually want to stream the items in your collection or is it because you just want to iterate through your collection using the functional API that stream offers?
For...
Try Enumerables.
It has multireduce function designed especially to aggregate multiple values during a single iteration:
List<Request> requests = Arrays.asList(
new Request(id++, 20, 59.28),
new Request(id++, 10, 61.23),
new Request(id++, 30, 60.67),
...
Try Enumerables.
It's a wrapper for Iterable which gives you all the functional goodies Stream has. And because it implements Iterable you don't have to collect the results into a list etc. if you don't want to.
Iterable<String> list = new ArrayList<String>();
Enumerable<String> enumerable = En...
I wrote this code in C++ to convert an array to a Binary Tree.
eg:- int nums[] = { 7,5,9,1,7,3} to a binary tree (root-7,root's left child-5, root's right child-9...).
is there any shorter way to do this?
#include <iostream>
#include <cstdlib>
#include <cstdio>
template<class E>

I'm a relatively new (~6 mos) developer, and I'm hoping for some feedback on my code style/structure. While I'm particularly interested in efficiency and maintainability, I'm open to feedback regarding anything that comes to mind from more experienced developers.

I've written a simple command line todo-list in Haskell.
The full code can be found here. However, given people's time constraints, I have selected three verbose functions for review.

You're a bit inconsistent with how you handle large argument lists. The large argument lists also make your code unreadable (or at least hard to read). I have trouble discerning the parts where your code does actual work and the parts where checks and logging happens.

When integration testing Rails applications HTTP request helpers can take a string or a named route as the first argument.
I find myself writing:
test "user visits edit page" do
homer = users(:homer)
get "users/#{homer.id}/edit"
assert_response :success
end
But I can also write:
test "...
There isn't much to say about the markup here - it looks like much was stripped from the markup. One thing though:
<Border BorderBrush="Black" BorderThickness="1">
<Image Source="MyImage.png"/>
</Border>
I wouldn't hard-code paths into the XAML like this...
