  • Things in .NET Framework 4 that every programmer should know

    - by Faruz
    I recently moved to Visual Studio 2010 and upgraded my website to work with .NET Framework 4. (From VS 2008 - Framework 3.5) What are things I need to know to improve site speed, readability or memory use? For example, I found out that when I use AJAX ScriptManager, one of it's new properties is EnableCDN which enables me to load AJAX .js files from Microsoft CDN.

  • Subversion: Change working directory's target repo

    - by Aiden Bell
    I know, other RCS are better, but... I have moved an SVN repository from file:///path/to/repo to http://host.name/svn/repo but there is a working directory (checkout out from file://) with changes that want commiting to the http location. How then, can I change the repo a working directory will commit to when issuing svn commit? I'd rather do that than checkout a new copy and sync changes locally. Also, handy to know for the future.

  • Address of default RHEL YUM Repository

    - by El Guapo
    Does anyone know the address of the default RHEL repository? We rent a server that is hosted by a third-party and one of our users seems to have "deleted" a lot of the RHN packages from our box; included was the rhn-yum-plugin. I really don't want to waste one our support requests on having them load up the DVD into the box and re-initializing the RHN software. Thanks.

  • Remember (persist) the filter, sort order and current page of jqGrid

    - by Jimbo
    My application users asked if it were possible for pages that contain a jqGrid to remember the filter, sort order and current page of the grid (because when they click a grid item to carry out a task and then go back to it they'd like it to be "as they left it") Cookies seem to be the way forward, but how to get the page to load these and set them in the grid before it makes its first data request is a little beyond me at this stage. Does anyone have any experience with this kind of thing with jqGrid? Thanks!

  • Is it possible to do DNS-based ACLs on a Cisco ASA?

    - by pickles
    Short of using static IP addresses, is it possible to have a Cisco ASA use a DNS name rather than an IP address? For instance, if I want to limit a host in the DMZ to access only one particular web service, but that web service might be globally load balanced or using DynDNS or cloud, how can the ACL be expressed so that a fixed IP address isn't used and the admin doesn't have to keep opening and closing down IP addresses?

  • Howto check if two hosts are the same

    - by Michael Stoll
    Hi, I just came across an issue, where I had to check if a path points into a windows share. Part of this problem is to check if host A is the same as host B. Where host A and host B can be one of the following {IPv4-Address, IPv6-Address, Hostname, FQDN}. As I do not need to be exact it's enough to resolve and compare the IP-Addresses in my case. But is there, theoretically, a method to check if the hosts are the same?

  • user specifc maven settings in repository

    - by Samuel
    http://maven.apache.org/settings.html As per documentation the user specific settings can be either copied to the .m2 folder or under the maven installation. If a developer changes a machine or gets a new user id, such properties have to be copied manually to these newer machines. Would it be possible to store user specific setting information in the repository itself (say SVN) and somehow have the mvn scripts load it on startup.

  • What to have in mind when building a AJAX-based webapp

    - by Industrial
    Hi everyone, We're in the first steps of what will be a AJAX-based webapp where information and generated HTML will be sent backwards and forwards with the help of JSON/POST techniques. We're able to get the data out quickly without putting to much load on the database with the help of a cache-layer that features memcached as well as disc-based cache. Besides that - what's essential to have in mind when designing AJAX heavy webapps? Thanks a lot,
