• Flash Browser? Flash Server Side?

  - by Abs

  Hello all, I have two noobish questions about Flash, Actionscript, Flex etc. 1) With these technologies is it possible to create a simple web browser that can render websites? 2) Is it possible to run these technologies on the server side? I am guessing no as Flash requires a browser to run within? Thanks all for any help

• Fast way to compute the minimal distance of two sets of k-dimensional vectors

  - by vrld

  I two sets of k-dimensional vectors, where k is around 500 and the number of vectors is usually smaller. I want to compute the (arbitrarily defined) minimal distance between the two sets. A naive approach would be this: (loop for a in set1 for b in set2 minimizing (distance a b)) However, this requires O(n² * distance) computations. Is there a faster way of doing this?

• Retrieve all records in a table with nHibernate

  - by brainimus

  I need to retrieve all the records in a table with nHibernate. If I had the key for all the records in the table I could loop and use nHibernate's Get method (this seems inefficient though) but I don't have the keys. I could also use FindAll but this requires criteria or a stored procedure. How can I get all the records from the table?

• How to get the ID of the last insert.

  - by James Jeffery

  I have an application and around 20 accounts are created per minute (on average). I need to implement a new feature which requires the ID of the last insert. I am using PDO. The question is, lets say 5 users create accounts at exactly the same time. Will it return the ID from the database for that users profile that was just created, or will it return the last insert? If you get what I mean.

• Does Silverlight require the .NET framework to be installed?

  - by Mohit Deshpande

  I have been exploring the possibilities of Microsoft Silverlight and how it runs in web browsers. I just wonder if Silverlight requires the .NET framework? Meaning that Mac or Linux users cannot run Silverlight. I will be making the application using the .NET framework 3.5. Will this application run in any web browser, or just major ones like Internet Explorer, Firefox, or Safari?

• What's the best replacement for timeGetTime to avoid wrap-around?

  - by phjr

  timeGetTime seems to be quite good to query for system time. However, its return value is 32-bit only, so it wraps around every 49 days approx. It's not too hard to detect the rollover in calling code, but it adds some complexity, and (worse) requires keeping a state. Is there some replacement for timeGetTime that would not have this wrap-around problem (probably by returning a 64-bit value), and have roughly the same precision and cost?

  In javascript I am used to just being able to pick any character from a string like "exm[2]" and it would return to me the third character in a string. In C is there a way to do that or something without a function that requires a buffer?

  - by user249490

  Hi, I have an application which runs a tool that requires network connection.

• How can I find places where tabs are used in a commit range?

  - by Mike

  I am contributing code to an open source project which requires that no tabs exist in source code(only spaces). I am sure I have used tabs accidentally in some places, and want to clean up my code before I submit a patch. How can I find uses of tabs in a commit range?

• Remember JVM state before executing a specific instruction.

  - by user559064

  I am working on a testing project using mutating technique. My project requires to manipulate a Java classfile and re-execute the classfile multiple times for testing. My implementation need to re-execute the whole system again after one manipulation, and that is not efficient. I am wondering whether I can save the JVM state right before executing a desired instruction in the classfile, so that I can start from that state after each manipulation. Thank you.

• Is it possible to unpage all memory in Windows?

  - by Hack59

  I have plenty of RAM, however, after starting and finishing a large number of processes, it seems that most of the applications' virtual memory has been paged to disk, and switching to any of the older processes requires a very long time to load the memory back into RAM. Is there a way, either via Windows API or via kernel call, to get Windows to unpage all (or as much as possible) memory? Maybe by stepping through the list of running processes and get the memory manager to unpage each process's memory?

• How can I programmatically change my windows domain password?

  - by Deestan

  In other words, how to change my password without going through the "CTRL-ALT-DEL - Change Password" interface. By programmatically I mean via a command-line tool, C# via a .NET library, COM-invocation via Python, ... whatever doesn't involve any manual steps, really. The "NET USER" command is ineligible, as it requires me to run with domain administrator privileges.

• Algorithm to rotate an image 90 degrees in place? (No extra memory)

  - by user9876

  In an embedded C app, I have a large image that I'd like to rotate by 90 degrees. Currently I use the well-known simple algorithm to do this. However, this algorithm requires me to make another copy of the image. I'd like to avoid allocating memory for a copy, I'd rather rotate it in-place. Since the image isn't square, this is tricky. Does anyone know of a suitable algorithm?

• methods of joining 2 tables without using JOIN or SELECT more than one distinct table in the query

  - by GB_J

  Is there a way of joining results from 2 tables without using JOIN or SELECT from more than one table? The reason being the database im working with requires queries that only contain SELECT, FROM, and WHERE clauses containing only one distinct table. I do, however, need information from other tables for the project i'm working on. More info: the querier returns the query results in a .csv format, is there something we can manipulate there?

• Limited-length string class

  - by wood_brian

  Is there a limited-length string class around? I've searched a little on the net and didn't find anything. I'm interested in a class that limits (possibly at compile time) the length to 255, so marshalling the string's length only requires one byte.

• Dynamic webpage content

  - by SQLiteNoob

  I have a website with a jQuery UI navigation, and I've got ajax working to dynamically change content between html files. I'm basically just replacing the contents of certain div ids with the contents of other div ids. This still requires numerous HTML files and I was wondering if there was a way to have a single html file and load content into the main page from it instead? What about an xml file? Thanks for the tips and advice about best practices and possible solutions.
