• for x in y, type iteration in python. Can I find out what iteration I'm currently on?

  - by foo

  Hi, I have a question about the loop construct in Python in the form of: for x in y: In my case y is a line read from a file and x is separate characters. I would like to put a space after every pair of characters in the output, like this: aa bb cc dd etc. So, I would like to know the current iteration. Is it possible, or do I need to use a more traditional C style for loop with an index?

• How does a cryptographically secure random number generator work?

  - by Byron Whitlock

  I understand how standard random number generators work. But when working with crytpography, the random numbers really have to be random. I know there are instruments that read cosmic white noise to help generate secure hashes, but your standard PC doesn't have this. How does a cryptographically secure random number generator get its values with no repeatable patterns?

• Entity binding WPF

• Fluent NHibernate Column Mapping with Reserved Word

  - by Josh Close

  I've read that using a back tick ` should allow for using of reserved words. I'm using SQL Server and Fluent NHibernate and have a column name "File". If I map it with "`File" it tries using [Fil] so it's adding the brackets correctly, but dropping the "e" from the end. If I map it as "`Filee" it uses [File] correctly. Am I doing something wrong or is this a bug in NHibernate or Fluent Nhibernate?

• Deploying and hosting scala in the cloud?

  - by TiansHUo

  I am starting a web app considering scalability as one of the top priorities. What would be the benefits of this: cassandra scala lift vs the traditional LAMP on the cloud? Since from what I've read, please correct me, the cloud itself is scalable I have never seen anyone deploy scala on the cloud before. Is it worth the effort to learn the platform? Is it ready for production use?

• Saving the modified contents of a pdf

  - by Anthony Webb

  I've got a form that I downloaded, I'd like to prefill some content on the form (this is easy using cfpdfform). Where it gets tricky is I would like to allow the user to modify the contents of that form, and then somehow have those modified contents accessible to me. I didnt build the source PDF so I dont know how to allow the user to "save" the new contents so they can be read. Any ideas on where I might start on this one?

• dynamic page caching- show redirected html cache page or show the dynamic page?

  - by i need help

  would like your comments. Eg: When user first visit www.testing.com/productdetailpage.asp I will use caching- store the whole page into productdetailpage.html When the user go to reopen productdetailpage.asp, user will be redirected to www.testing.com/productdetailpage.html It means they will see productdetailpage.html, not .asp Is this a good way? Any implication in terms of SEO and other part? Will it be better to read datas from .html into .asp and show the final page as .asp all the time?

• Unit Testing - not testable code converted to testable code

  - by imak

  I have read so many places is that if your code is not test-able that mean code is not well written. So that makes me start writing a code that is test-able and to start using some unit testing framework. With this though I start looking for some example with piece of code that is not testable and gradually converted to a testable code. I find tons of examples on unit testing but if someone can provide an example like above it probably can jump start things for me. TIA

• Gimpel's PC-lint and Flexelint; Anyone used them?

  - by samoz

  So I've read a few magazine articles and the website for Gimpel's PC-lint and Flexelint C/C++ compiler. It's really expensive (at least for me), but it seems like it might have some merit to warrant the cost. So I'm wondering if anyone else has used/bought them and can provide their opinions?

• Can't get the JSONP workin' with WCF Data Services...

  - by SevilNatas

  What am I missing here? It seems from all that I read and watched, exposing JSON from a WCF Data Service should be as easy as adding the '[JSONPSupportBehavior]' directive in front of the Service Class. Problem is VS2010 doesn't recognize 'JSONPSupportBehavior'. Is there a reference I am missing? Seemed like, from alll the articles, it was supportted outta the box. TIA S.

• Monovation: Assembly Injection into Live Processes

  - by FlappySocks

  I read this article by Miguel de Icaza on attaching an assembly into a live mono process. How is this any different to attaching a DLL to a running process? I do this already, but once the DLL is attached, it can't be unloaded without using an AppDomain (which I am trying to avoid). Miguel talks about "patch[ing] running programs", but I don't understand how. I cant find any other documentation or examples on this.

• jQuery for XUL?
