I had a bit of an issue with my last piece of code, having to do with cleaning up resources. I needed a way to ensure the database connection was always properly closed, even if there still were instances of an IPresenter or IRepository still floating around.

For a long while, I've been wanting to find answers in the tags I'm interested in, because I like spending my votes.
I've given up hoping for a chatroom-friendly answers RSS feed, so I ended up spending my votes on whatever I see that's interesting and good for the site.
Recently I was looking ...
I am new to R. Please forgive me if you think this question is too simple. I saw one example like this lately.
x <- factor ( c( "yes", "yes", "no", "yes", "no" ) )
attr (, "levels")
I understand attr in R is used to find the attributes of an object. What does "," mean here ? Many thanks.
This is the second project for my CS1 class, this time I'm actually getting it reviewed before I submit it ;)
The Harris-Benedict equation estimates the number of calories your
body needs to maintain your weight if you do no exercise. This is
called your basal metabolic rate, or BMR.

I think the factory class is completely unnecessary. I don't see how you're saving 200 lines out of a single file either.
The way I see it, the code in DTTowerFactory.m comes from several different files (and probably needs to go back to those files).

I just read about the new Samsung Galaxy Note Edge having a 2.7GHz quad-core processor and 3gb of Ram.
The laptop I bought last year by HP is 4 Gb of ram and 2.3GHz quad-core and my iMac is even older and is 2.5GHz i5.
My question is does this mean that the new Samsung gadget is more powerful...
I've been trying many things to get this to work. I've followed the documentation, as far as I know, and this is just not working.
Can any of you with experience in Postgres recommend a fix? I would be eternally grateful.

If the purpose of your post is to seek out the right term for moderators, I think there are two contexts that are significant, and there should thus be two collective expressions:
A Posse of moderators - people out to seek justice

I do this kind of thing all the time:
In addition to moving these declarations closer to where you use them as @lokiastari said, the initializations are pointless because you overwrite them anyway.
That is, when I mention a user, I don't just mention their (uhm, slightly mispelled) name, I ...
Here is the code that I wrote to print the LCS:

Besides what Pimgd has pointed out, I have some more things to say:
First of all, your code is a bit of a mess as the indentation is quite far off, and the spacing likewise. If you're using an IDE, which I hope that you are, use your IDE to automatically correct these things. Or look at Pimgd's ...
I created the code below to illustrate push-pull pattern with zmq and to benchmark some concurrent job.

var fib = function (n) {

Just wondering if there was any reason NOT to wrap a long query over multiple line via new lines vs using concatenation?
For example, consider this:

I'm having fun with Java's Stream library and lambdas.
The following code looks for persons within a list that have the same ID (which might indicate that something's wrong with the data) and prints out each group of people that share one ID.

The following question was taken from Absolute Java 5th ed. by Walter Savitch:

I'm trying to create a wrapper / factory around the cordova media plugin, which requires you to create a new Media object, and then use it again to pause, stop, play, etc it.

Actually, most of the leg work is done for us in the framework. Enum.GetValues returns the list sorted ascending already, via the underlying implementation of Type.GetEnumData.
With that in mind, you can use LINQ for the rest, retrieving all but the last value:
