  • How to create a test environnement on the production FTP

    - by Clement Herreman
    Hello, I'm currently working on a symfony webapp, which is already on production. To develop and add/delete/modify functionnality of the model, I work on my laptop, using symfony 'dev' environnemment. I test if everything work fine, then I pray a little and deploy it on the prod server (with all the risk of data error, like when I add new not null attributes on the model, prod server configuration special stuff, version of php/apache etc.). The problem is that I would like to setup a "staging" server, which would be a copy of the production server (same database, same configuration apache/php), so that, if the deployment goes bad, the production user stay untouched and working, only the staging server is down. But my client has only 1 FTP available. So, the question is : can I run 2 symfony project, with different models, on the same FTP ? Or is there another way to do what I want to do ? Thank you !

  • Creating a .bat file

    - by kiran826
    Hi, I am trying to execute a command CSRUN.exe with certain parameters from command prompt. I am able to do this using command prompt.

Following is the one i am executing from the command prompt, which i want to have in a batch file C:\Program Files\Windows Azure SDK\v1.1\bincsrun.exe E:\Publish\ServiceConfiguration.csx E:\Publish\ServiceConfiguration.cscfg /launchbrowser Can somebody suggest me how to create a batch file for invoking this command?

  • Using Mapped Memory Files in C# to store reference types

    - by Khash
    I need to store a dictionary to a file as fast as possible. Both key and value are objects and not guaranteed to be marked as Serializable. Also I prefer a method faster than serializing thousands of objects. So I looked into Mapped Memory Files support in .NET 4. However, it seems MemoryMappedViewAccessor only allows storage of structs and not reference types. Is there a way of storing the memory used by a reference type of a file and reconstructing the object from that blob of memory (without binary serialization)?

  • Sudo yum seems to fail on CentOS, but works fine after sudo -i

    - by Aron Rotteveel
    I am currently having some trouble with yum through sudo. For some reason, it does not seem to work: aron@graviton [/var/log]# sudo yum clean all There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: /usr/lib64/python2.4/lib-dynload/datetime.so: failed to map segment from shared object: Cannot allocate memory Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.4.3 (#1, Sep 3 2009, 15:37:37) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq The strange thing, however, is that it works fine when I gain root privileges through sudo -i first. Any ideas what might be causing this problem?

  • finger for Windows

    - by tearman
    Ok probably a bit of an odd question, but is there a way to enable "finger" like functionality on a Windows network? we'd basically like the ability to find out where a user is logged in on a network and possibly which users are logged onto a workstation if possible. We're currently on AD2003 functional level, with the intent of going to AD2008 very soon, so compatibility in that arena is preferable.

    - by Curchy
    I have a DataGridView bound on a generic list, in .NET 3.5. When this grid is resized, there is a residual traces that is left behind on the background of the grid where there is no items. This only occurs where there is some columns that have the WrapMode attribute set to True. It seems that only the content that is wrapped is not refreshed on the background of the grid. Anybody have a workaround or a resolution for this problem?

  • oracle drop index if exits

    - by CC
    How do you drop an index only if it exists? It seems simple but I did found anything on the net. The idea is to drop it only if it exists, because if not, I will have an error and my process stops.
