Java socket streams end unexpectedly
I have an application handling several Java socket connections to different kinds of remote machines (some PCs, others are embedded devices). These sockets and streams should not close indefinitely except for a very good reason (e.g. crash of remote system). I frequently encounter an issue where the input stream ends unexpectedly, witho...

java: StringBufferOutputWriter or StringBufferOutputStream?
I need to take a caught exception and get a String that is what would be printed using printStackTrace(). It looks like the simplest thing is to call printStackTrace(X), where X subclasses a PrintStream or PrintWriter, and gathers it to a StringBuilder and can return a String. Does such a thing exist? If not, any suggestions how to do ...

C# Stream Design Question
I have an appliction right now that is a pipeline design. In one the first stage it reads some data and files into a Stream. There are some intermediate stages that do stuff to the stream of data. And then there is a final stage that writes the stream out to somewhere. This all happens serially, one stage completes and then hands off to ...
Compose output streams
I'd like to compose two (or more) streams into one. My goal is that any output directed to cout, cerr, and clog also be outputted into a file, along with the original stream. (For when things are logged to the console, for example. After closing, I'd like to still be able to go back and view the output.) I was thinking of doing somethin...
Chunkinfying stream. Is code correct? Need a second set of eyes.
Can anyone see any obvious holes in my logic here. Basically I need to break up a byte array into chunks of 10,000 before sending it out: byte [] bytes = GetLargePieceOfData(); Stream stream = CreateAStream(); if (bytes.Length > 10000) { int pos = 0; int chunkSize = 10000; while (pos < bytes.Length) { if (...

Can STDOUT and STDERR use different colors under XTerm / Konsole?
Is it even achievable? We need STDERR (ie. other streams then STDOUT) to have different colo(u)r. For example red. We use bash, terminal should be Konsole (XTerm, gnome terminal or any usable). Thanks if you know :-) ...
C# OutOfMemoryException on MemoryStream writing
I have a little sample application I was working on trying to get some of the new .Net 4.0 Parallel Extensions going (they are very nice). I'm running into a (probably really stupid) problem with an OutOfMemoryException. My main app that I'm looking to plug this sample into reads some data and lots of files, does some processing on them,...
