Hi everyone, I'm working on a project sending serial data to control animation of LED lights, which need to stay in sync with an animation engine. There seems to be a large serial write buffer (OSX (POSIX) + FTDI chipset usb serial device), so without manually throttling calls to write(), the software can get several seconds ahead of th...
I'm developing an Asynchronous Game Server using .Net Socket Asynchronous Model( BeginAccept/EndAccept...etc.) The problem I'm facing is described like that: When I have only one client connected, the server response time is very fast but once a second client connects, the server response time increases too much. I've measured the time...

I need to knock up a very quick prototype/proof of concept application to demo to someone within the next couple of days so I've minimal time to research this as fully as I normally would. The set-up is a very simple database application running on a laptop - will only ever be a single user updating a couple of tables so I was thinking ...

I'm writing a wrapper class around a TcpClient which raises an event when data arrives. I'm using BeginRead and EndRead, but when the parent form handles the event, it's not running on the UI thread. I do I need to use delegates and pass the context into the callback? I thought that callbacks were a way to avoid this... void ReadCallbac...
Hi Masters, Good Day, I am new and very naive to Oracle DB. I am using Oracle 10G. Let me explain to you. I have one source database named ( DB1) and Target Database named (DB2). I have 2 schema's named dbs1 and dbs2 in the source database (DB1). I have exported both the database schemas in Source Database (DB1) and imported it suc...
We're moving a social media service to be on separate data centers as our other hosting provider's entire data center went down. Twice. This means that both websites need to be synchronized in some sense -- I'm less worried about the code of the pages, that's easy enough to sync, but they need to have the same database data. From my r...
I'm looking for parallel programs( parallel loops ) that can run in order, but has no message passing between processes, and has lots of synchronization. It should be possible to run the loop in any order, yet producing correct results, even if the result is not the same always. An example would be a ticket booking system, where the fir...

We have a .net 2-tier application where a desktop program is talking to a database. We support MS SQL Server 2000, 2005, 2008 and Oracle 9, 10 and 11. The application is sold, not as shrink-wrap, but pretty close. It is quite important for us that the installation and configuration is as easy as possible as installation instructions are...
I'm having trouble working out how to lock my application out of a section of code while it waits for a response from an external program I've used Synclock on a section of code with the Me object in the expression. In this Synclock I call an overridden ShowDialog method of a dialog box, which has a timeout parameter, but does return th...
Guys, Have you come across any solution that would allow me to sync an exchange accounts calendar, with a google calendar? I'm aware of the desktop sync client, but this requires Outlook to be running on some machine, somewhere. Which is something I'd like to try and avoid if possible. I can run the syncing app on some VPS or something...
Consider the following scenario. We have a C++ function with a static local variable: void function() { static int variable = obtain(); //blahblablah } the function needs to be called from multiple threads concurrently, so we add a critical section to avoid concurrent access to the static local: void functionThreadSafe() { ...
There is some cluster and there is some unix network daemon. This daemon is started on each cluster node, but only one can be active. When active daemon breaks (whether program breaks of node breaks), other node should become active. I could think of few possible algorithms, but I think there is some already done research on this and s...
