Understanding MongoDB BSON Document size limit
...plit its nested documents as individual documents in another collection or start a new "continuation" document (solutions I have used several times to work within this limit) had little impact on performance but big impacts on code complexity. The entire point of document DBs is data locality.

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,...
