• How do you draw a string centered vertically in Java?

  - by Paul Alexander

  I know it's a simple concept but I'm struggling with the font metrics. Centering horizontally isn't too hard but vertically seems a bit difficult. I've tried using the FontMetrics getAscent, getLeading, getXXXX methods in various combinations but no matter what I've tried the text is always off by a few pixels. Is there a way to measure the exact height of the text so that it is exactly centered.

• Synthesizing Singing

  - by anon

  So this is from the late 90s ... http://www.cs.princeton.edu/~prc/SingingSynth.html Why hasn't this taken off? (We can synthesize photorealistic like images, but the synthesis of singing ... still seems to be in very primitive stages). What exactly is it that makes the synthesis of singing difficult? http://www.interspeech2007.org/Technical/synthesis_of_singing_challenge.php <-- still seems primitive. Thanks!

• How do you perform address validation?

  - by Kevin Pang

  Is it even possible to perform address (physical, not e-mail) validation? It seems like the sheer number of address formats, even in the US alone, would make this a fairly difficult task. On the other hand, it seems like a task that would be necessary for several business requirements.

• Securing Coredata objects

  - by Abraham Durairaj

  I am working on an application which has got some sensitive information. I am aware that it would be difficult for a layman to hack into iphone to get the information. If I use SQLite directly I have something called SQLite Cipher to encrypt / encode the database. Is there anyway where I can have the same way of encrypting the coredata so it makes it hard for hackers to get into the data. Can someone shed some light on this? Thanks in Advance

• RegExp to validate a formula (string/boolean/numeric expression)?

  - by JSteve

  I have used regExp quit a bit of times but still far from being an expert. This time I want to validate a formula (or math expression) by regExp.

• Understanding EXE Internals

  - by Steve

  I was attempting to install an exe that requires a serial number before the install, which the vendor has not provided to us yet. This got my wheels turning about whether there is any information that can be gained from viewing an exe using a hex editor/VI/etc? Using VI to view an exe, I can see some sections of plain text, but it is difficult to determine what it refers to without any context around it. Is it possible to determine any information by reading an exe? Thanks

• Entitlement Web Service Authentication

  - by jesusOmar

  I was tasked with implementing either a SAML authentication service, or a EWS (Entitlement Web Service Authentication) service, and I was wondering if anyone has any samples or documentation on such options. I am almost 100% sure that SAML is out of the question due to the time frame of the project. EWS has been difficult to find online, I can't seem to find any good samples or documentation on implementing such service.

• Looking for a good C++ based RSS API

  - by Rhubarb

  I tried http://code.google.com/p/feed-reader-lib but holy cow, talk about difficult to build. It has a nightmare of dependencies on Xerces and Xalan, both of which seem to be choking under the new VisualStudio 2010 C++ compiler. I've wasted hours trying to build this thing which is a shame. Does anyone have anything a little easier to hit the ground running with?
