• What does it mean when a ByteInputStream keeps returning 0?

  - by Zombies

  I have a ByteInputStream, created from a Socket in Java. The connection is to a simple web server that uses chunked transfer encoding. The web server does in fact work in normal browser. But in my program, I am attempting to read, I read the first first bytes (some 5kb of data). But each read after that returns 0 bytes read. Isn't it supposed to block until it can read?

• Drupal blocks are syncing?

  - by Kevin

  I am trying to enable a new theme on a site running Drupal 6.16. I enable it fine, it has its own namespace in the theme and theme registry. However when you go to the Blocks section, changing a block here will affect that blocks placement in all the other themes, and vice versa. Is this normal behavior? Where should I begin looking to solve this issue?

• Java overloading and overriding

  - by Padmanabh

  We always say that method overloading is static polymorphism and overriding is runtime polymorphism. What exactly do we mean by static here? Is the call to a method resolved on compiling the code? So whats the difference between normal method call and calling a final method? Which one is linked at compile time?

• Establish SSH Connection Between Two Isolated Machines Using a 3rd System

  - by FurryHead

  I'd like to do the following with Python: Computer 1 starts SSH server (probably using twisted or paramiko) Computer 1 connects to Server 1 (idle connection) Computer 2 connects to Server 1 Server 1 forwards Computer 2's connection to Computer 1 (connection no longer idle) Computer 1 forwards Server 1's connection to listening SSH port (on computer 1) Result being Computer 2 now has a SSH session with Computer 1, almost as if Computer 2 had started a normal SSH session (but with Server 1's IP instead of Computer 1's) I need this because I can't port forward on Computer 1's network (the router doesn't support it).

  Normally all validation methods is connected to a field, radiobuttons, dropdowns etc. In my case I would like to do a general custom validation that depends on many fields in my form.

• matlab: subs on symbolic constant returns scalar instead of vector for a vector input

  - by noam

  usually, symbolic functions return vectors for vector inputs: syms('x'); f=x*2; subs(f,[1 2 3]) outputs: [2 4 6] but doing f=sym('0'); subs(f,[1 2 3]); outputs: 0 and not: [0 0 0] so basically, my questions is how do I make f behave as a "normal" symbolic function. I can do something ugly like f=x-x to create a function that always returns zero, but is there a prettier way?

• Can't create packages with Maven webapp

  - by cardori

  I have created a project using the following maven webapp project in eclipse: When adding a package to the project (right click project - new - package), the package gets added as a folder (I added a package named core). It does not have the usual package icon: If I try to create a new class and select a package, there are no entries in the list box. I have tried creating packages in a normal eclipse dynamic web project and these work correctly. How do I get packages in Maven enabled webapp projects?

• How to 'Bridge'/'Stream'/'Forward' an Incoming HTTP Connection (Advanced Proxy)

  - by mykl

  Not sure if this is possible..basically a server forwards/bridges an incoming connection Client - Server - Destination Now, rather than a normal proxy script on the server(or a simple redirect), 1) the Destination sees the incoming connection as from the CLIENT (not from the SERVER).. aka masking the server 2) the Server in the middle streams the data back to the client(without downloading it first, then passing it) Anyone know how to do this or something like it in PHP ?

• scaffold does not update view

  - by doemsche

  Hi there I have a question to the following procedure: script/generate scaffold product title:string description:text db:migrate #then I generate a migration which adds a column description to the table products and migrate the db again. My question is: why is the field description not added to the project-views? Is that normal rails scaffold behaviour? I think I saw in a video tutorial that the scaffold updates as well the views, which would be very convenient. Thanks in advance for any help!

• Generate service layer with Hibernate

  - by gmate

  Hi all! I generate *.hbm.xml mapping files and *.java file from the DB schema, with Hibernate tools. My question is, that is there any option, to generate service classes also? These are the classes where I implement the store(), find(), delete(), etc... methods. I know that for C# there are many solutions to generate almost everything. I'm looking for the same, but with Hibernate. Is there any? Thanks for every reply in advance!

• Is there an efficient way to query a document database?

  - by Zubair

  Since document databases store records in tree like structures the fields will never be at set positions. Does this make querying a document database inefficient, or would indexes just be used as with a normal relational database?

• Splitting a double in two, C#

  - by Stacey

  I'm attempting to use a double to represent a bit of a dual-value type in a database that must sometimes accept two values, and sometimes accept only one (int). So the field is a float in the database, and in my C# code, it is a double (since mapping it via EF makes it a double for some reason... ) So basically what I want to do .. let's say 2.5 is the value. I want to separate that out into 2, and 5. Is there any implicit way to go about this?

• C# What is the sense of Application.Exit Method ?

  - by PaN1C_Showt1Me

  I'm asking this question, because I can't figure out when I could find an use of this method. If I've designed everything correctly then I should be able by the medium of normal returns and try catch clauses to handle all problems and end the application in a correct manner. Am I wrong ?
