LIKE vs CONTAINS on SQL Server
...le.
The first query, using LIKE, will be unable to use an index, since it starts with a wildcard, so will always require a full table scan.
The CONTAINS query should be:
SELECT * FROM table WHERE CONTAINS(Column, 'test');

Faye vs. Socket.IO (and Juggernaut)
... should be absolutely trivial to get going with. I'ts really simple to get started with but its extensibility means it can be customized in quite powerful ways, for example you can turn it into a server-to-client push service (i.e. stop arbitrary clients pushing to it) by adding authentication exten...
What are major differences between C# and Java?
...
@OrangeDog: For a start, most developers don't write code using "unsafe" as far as I'm aware, so that's a red herring. I also think that provability is a red herring - I don't think formal provability has very much to do with how easy it is fo...
What is the difference between supervised learning and unsupervised learning? [closed]
...ce). In semi-supervised learning, there are two different algorithms which start with the labeled examples, and then "tell" each other the way they think about some large number of unlabeled data. From this "discussion" they learn.

What is the difference (if any) between Html.Partial(view, model) and Html.RenderPartial(view,model)
...put stream is better (which was why they went w/ the void RenderPartial to start with). Partial is mostly useful (imo) in testing, though as SLaks said there may be some places that you want to manipulate the output before rendering it in production code. They're just rare, imo.

Why fragments, and when to use fragments instead of activities?
...e intents. When you press something in a Fragment you would typically call StartActivity() with data on it. The intent is passed on to all fragments of the activity you launch.

Correct idiom for managing multiple chained resources in try-with-resources block?
...ny of the constructors. Assuming you added an S to the above chain (so you start with a V and end with an S, by applying U, T, and S in turn), you get the same either if you first chain S and T, then U, corresponding to (ST)U, or if you first chained T and U, then S, corresponding to S(TU). However,...
How to check whether a script is running under Node.js?
...ricks we can use to figure out for sure what environment you are in.
Lets start out with the generally accepted solution that's used in the underscore library:
typeof module !== 'undefined' && module.exports
This technique is actually perfectly fine for the server side, as when the requir...
How do you do a case insensitive search using a pattern modifier using less?
...NSI colour sequences.
Another little used feature of less that I found is starting it with +F as an argument (or hitting SHIFT+F while in less). This causes it to follow the file you've opened, in the same way that tail -f <file> will. Very handy if you're watching log files from an applicati...
