• Alternatives to "Raining Sockets"

  - by sanity

  I need to build a Java app with considerable IO requirements, supporting tens of thousands of concurrent TCP connections. I found a library called Raining Sockets which seems intended to make it easier to use Java's asynchronous NIO package, but the last update was 6 years ago. Are there other libraries, that are preferably still under active development, and with a public maven repository, that I should look at?

  - by asksuperuser

  I tried this sample here: http://9elements.com/io/projects/html5/canvas/ After a few minutes, Firefox slows down so much I can't even popup any menu. When I closed the tab, Firefox comes back to normal again. So is HTML 5 really a good choice now ?

• Best practices for handling binary data in Ruby?

  - by StackedCrooked

  What are the best practices for reading and writing binary data in Ruby? In the code sample below I needed to send a binary file using over HTTP (as POST data): f = File.new("resp.der", "r") # binary file begin while true out.syswrite(f.sysread(1)) # out is an output stream (type IO) end rescue EOFError => err puts "Sent response." end While this code seems to do a good job, it probably isn't very idiomatic. How can I improve it?

• Filter to values in collection in one query

  - by dotnetdev

  Hi, I have the following LINQ query: List<string> Types = (List<string>) Directory.GetFiles(@"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727") Where(x => System.IO.Path.GetFileNameWithoutExtension(x).Contains("Microsoft")) .ToList<string>(); How could I modify this so it can only get the values stored in a collection, without writing another LINQ query (which I assume will impact performance?)? Thanks

• Find user independent TEMP directory with Java

  - by GHad

  Hi, when running a Java application as service with the user 'LocalService', the temp directory ("java.io.tmpdir") points to 'c:/windows/temp' (for example). Running a Java application normally gives 'c:/documents and settings/user/local settings/temp' instead. How can I determine the user independent temp folder 'c:/windows/temp' when my application runs normally? Thanks and greetings, GHad

• Concurrent processes do not utilize all available CPU

  - by metdos

  I run some processes on an EC2 cc2.8xlarge instance which has 32 virtual processors. For some type of processes, when I run 16 processes on parallel, all of them use 100% of CPU cycles. But for other type of processes, they are not using 100% CPU and they finish considerably slower than a single thread. There is no time spend on IO and all data is served from memory. Do you have any idea about the reason of this problem?
