• Need a simple tool for analysing unicode characters

  - by Steve Bennett

  I'm surprised I can't find a simple tool for this. Basically, sometimes as a result of text munging, or using some piece of software, I end up with some text that has some troublesome characters - such as looking a lot like other characters, but being distinct from them. I'd like a tool (preferably online, javascript based) where I can paste the text, and it will tell me all the characters involved, their names, unicode codes etc.

• Scalable Ticketing / Festival Website

  - by Luke Lowrey

  I've noticed major music festivals (at least in Australia) and other events that experience a peak in traffic when tickets go on sale have huge problems keeping their websites running well. I've seen a few different techniques used to try combat this such as short sessions and virtual queues but they dont seem to have much effect. If you were to design a website to sell a lot of tickets in a short amount of time how would you handle scalability? What technologies and programming techniques would you use?

• Handling connection errors in a MDB

  - by Rafa de Castro

  Is it possible to manage connection timeouts or errors in a MessageDrivenBean? You can make the factory to retry connecting a certain number of times but... is it possible to make some actions each time that a reconnection retrial is neccesary?

• Should a Stack have a maximum size?

  - by Sotirios Delimanolis

  I'm practicing my knowledge of ADTs by implementing some data structures, even if most already exist. With Stacks, a lot of books and other documentation I've read talk about the stack throwing an error when you try to add an element but the stack is full. In a java implementation (or any other), should I specifically keep track of a maximum stack size (from constructor), check to see if that size is reached, and throw an overflow exception if it is? Or is not such a big deal?

• When do we use MVVM?

  - by AKRamkumar

  I have been hearing a lot of hype about MVVM for WPF. When do we use it? Is it a use for everything or does it only have specific uses? Is it worth it for every project?

• Memory layout of executable

  - by Ross

  Hi all, When loading an executable then segments like the code, data, bss and so on need to be placed in memory. I am just wondering, if someone could tell me where on a standard x86 for example the libc library is placed. Is that at the top or bottom of memory. My guess is at the bottom, close to the application code, ie., that would look something like this here: --------- 0x1000 Stack | V ^ | Heap ---------- Data + BSS ---------- App Code ---------- libc ---------- 0x0000 Thanks a lot, Ross

• Can SharedCache be used to distribute session cache in .NET?

  - by Matt W

  I've read a lot about ScaleOut, NCache and MemCached, but I can't find anywhere a mention that SharedCache can provide the same basic Session distribution support that the others can. Is it only limited to providing Cache support or can I spread the load of my Session with it? Thanks, Matt.

• Using a Linq-To-SQL class automagically generates the connection string for me; is there a way to ma

  - by Sergio Tapia

  I'm just beginning to use Linq-to-SQL and it's just wonderful to use. The problem is, this software is going to be run on a lot of machines and each machine will have a unique connection string. Is there a way for me to manually set the connection the Linq-to-SQL (.dbml) uses? The way I'm doing things now is creating the .dbml file, and in the graphic designer I'm dragging tables from the Server Explorer to the white board of the .dbml.

• What happens when a user presses stop in their web browser?

  - by Jon Winstanley

  If a page is called that requires a lot of processing and the user clicks stop before the end, does the browser simply stop the request at the client side? Or is a 'stop' message sent to the server, i.e. is the processing cancelled?

• Debugging embedded Lua

  - by Caspin

  How do you debug lua code embedded in a c++ application? From what I gather, either I need to buy a special IDE and link in their special lua runtime (ugh). Or I need to build a debug console in to the game engine, using the lua debug API calls. I am leaning toward writing my own debug console, but it seems like a lot of work. Time that I could better spend polishing the other portions of the game.

• Does access/write to Boolean object needs synchronization

  - by Suraj Chandran

  This may seem a very silly question. Consider this: I have a simple Boolean object with a getter and a setter. Now both of the methods are called from a lot of threads very frequently. Do I need to have a synchronization for this boolean? Also are Boolean assignments atomic operations?

• Java RegExp ViewState

  - by CDSO1

  I am porting some functionality from a C++ application to java. This involves reading non-modifiable data files that contain regular expressions. A lot of the data files contain regular expressions that look similar to the following: (?<=id="VIEWSTATE".*?value=").*?(?=") These regular expressions produce the following error: "Look-behind group does not have an obvious maximum length near index XX" In C++ the engine being used supported these expressions. Is there another form of regexp that can produce the same result that can be generated using expressions like my example as input?

• Should design, architecture and modeling be part of education?

  - by Gabriel Šcerbák

  I often heard, that those things cannot be teached, because you can master them only through good gut feeling fed with years of experience. However various patterns and principles are quite well documented and I start to think, that you can actually learn quite a lot of good stuff from books, training and exercises. What is your uptake?

• Is there a solution that lets Node.js act as an HTTP reverse proxy?

  - by Igor Zinov'yev

  Our company has a project that right now uses nginx as a reverse proxy for serving static content and supporting comet connections. We use long polling connections to get rid of constant refresh requests and let users get updates immediately. Now, I know there is a lot of code already written for Node.js, but is there a solution that lets Node.js act as a reverse proxy for serving static content as nginx does? Or maybe there is a framework that allows to quickly develop such a layer using Node.js?
