Any reason why scala does not explicitly support dependent types?
...a {
| val foo = foo1
| val bar = new foo.Bar
| }
sigma: java.lang.Object with Sigma{val bar: this.foo.Bar} = $anon$1@e3fabd8
and in fact, this is a crucial part of the encoding of dependent method types which is needed to escape from the 'Bakery of Doom' in Scala prior to 2.10 (...
Why would you use String.Equals over ==? [duplicate]
...'s entirely likely that a large portion of the developer base comes from a Java background where using == to compare strings is wrong and doesn't work.
In C# there's no (practical) difference (for strings) as long as they are typed as string.
If they are typed as object or T then see other answers...
What is the best algorithm for overriding GetHashCode?
...something like the implementation given in Josh Bloch's fabulous Effective Java. It's fast and creates a pretty good hash which is unlikely to cause collisions. Pick two different prime numbers, e.g. 17 and 23, and do:
public override int GetHashCode()
{
unchecked // Overflow is fine, just wrap...
When to use Hadoop, HBase, Hive and Pig?
...natively you can write sequential programs using other HBase APIs, such as Java, to put or fetch the data. But we use Hadoop, HBase etc to deal with gigantic amounts of data, so that doesn't make much sense. Using normal sequential programs would be highly inefficient when your data is too huge.

How do you properly use namespaces in C++?
I come from a Java background, where packages are used, not namespaces. I'm used to putting classes that work together to form a complete object into packages, and then reusing them later from that package. But now I'm working in C++.

Under what conditions is a JSESSIONID created?
...about one more source of the JSESSIONID cookie:
I was just debugging some Java code that runs on a tomcat server. I was not calling request.getSession() explicitly anywhere in my code but I noticed that a JSESSIONID cookie was still being set.
I finally took a look at the generated Java code corr...
Explaining Apache ZooKeeper
...eady present, but can be written above the ZooKeeper primitives.
If the C/Java API is too unwieldy for your purposes, you should rely on libraries built on ZooKeeper such as cages and especially curator.

Appending an element to the end of a list in Scala

Convert PDF to clean SVG? [closed]
...here are some good tools for trying it out (e.g. PDFReader will display as Java Graphics2D). You can intercept the graphics tool with an SVG tool like Batik (I do this and it gives good capture).
There is no simple way to convert all PDF to SVG - it depends on the strategy and tools used to create ...
