• How do i know what unixtime a php session will expire?

  - by Steve

  Hi How do I know how many seconds it will be until a php session expires? I'm building a web application where users might spend a lot of time typing into big text fields, but for security reasons I still want sessions to time out after a reasonably short period. I want to warn them if their session is about to expire so they can save or take some other action to keep it alive. Any tips? thanks!

• is there anyway to know if your supposedly fully dedicated server is really a virtually resource-sha

  - by siran

  Hi, sometimes I feel my server not responding as smoothly as I would expect (i have a Intel(R) Xeon(TM) CPU 2.80GHz Quad Core), given that for example, the 'top' commands reports a low load < 0.5, CPU are almost completely idle ... I maybe have internet connectivity issues, so I don't really know if it's me or if it's the server itself. Is there anykind of benchmarking script (or something analogous) I could run and see the actual performance of the server ?

• Do you know of a log4net appender which rolls on date, but let's you limit the total number of files

  - by Michal Drozdowicz

  Hi, I need to define an appender for log4net in a way that I get one log file for each day, but the total number of files are limited to, let's say, 30. That is I want to keep only the logs not older then 30 days, delete the older ones. I've tried doing it with RollingFileAppender, but it seems that specifying a limit of files to keep is not supported. Do you know of an alternative solution that I could use?

  - by Jeffrey Aylesworth

  Programs on Linux install data for programs into $PREFIX/share/programname, how does the program know where that is, does it need to be compiled in? Would it be suitable to assume that the binary is in $PREFIX/bin, and use that to determine $PREFIX? This only needs to work on Linux, and specifically, I am using C.

• Does anybody know of an Atom APP server for .Net?

  - by ianmayo

  Hi all, I'm aware of the Argotic framework for .Net that assists in the collation and management of Atom data, but does anybody know of a .Net application/framework that implements the Atom Publishing Protocol (APP)? Creating a .Net APP server from scratch seems a daunting task, even if it 'stands on the shoulders' of Argotic. Maybe a .Net rewrite of Apache Abdera (or other O/S implementation) would be easier. I welcome your thoughts, Ian

• Does anyone know of a spell check library that underlines text?

  - by Icono123

  Does anyone know of a C# spell check library that would underline misspelled works in a windows form text box? In the past, I've used NetSpell and works great if users use the dialog box. I'm thinking I might be able to automatically call the spell check while text is being updated and underline the text. Anyone have any good ideas on what would be the best way to go about doing it?
