Our rails app is designed as a single code base linking to multiple client databases. Based on the subdomain the app determines which db to connect to.
We use liquid templates to customise the presentation for each client. We are unable to customise the generic 'We're Sorry, somethign went wrong..' message for each ... |
How to have silverlight get its data from MySQL |

I've written a small hello world test app in Silverlight which i want to host on a Linux/Apache2 server. I want the data to come from MySQL (or some other linux compatible db) so that I can databind to things in the db.

Just to illustrate the remarks of the previous answers urging you to use table instead of div for _tabular_ data:
**[CSS Table gallery][1]** is a great way to display beautiful tables in many many different visual styles.

In XPath 2.0 and XQuery 1.0 you can test against the namespace prefix using the [in-scope-prefixes()][1] function in a predicate.
e.g.
//*[in-scope-prefixes(.)='html']
If you cant use v2, in XPath 1.0 you can use the [namespace-uri()][2] function to test against the namespace itself.
e.g.

Are you running on virtual or physical servers? We found that it is significantly faster on physical servers. Also, check the disk performance - if you are running the servers from a SAN it might be a sign that your SAN is over utilised. |
Try to separate your content and layout from your code as much as possible. Any time you write any HTML in a .php file, stop and think "Does this _really_ belong here?"
One solution is to use templates. Look at the [Smarty](http://www.smarty.net) templating system for a pretty easy-to-use option. |

If you only need it to check when the user asks rather then all the time, don't use the FileSystemWatcher. Especially if it's a shared resource - the last thing you want is 50 client machines watching the same shared directory.

I think it should be a combination of user-name plus IP block. Not just IP. |
You need a framework. This will not only make your code pretty (because of the already-mentioned model-view-controller pattern, MVC) - it will save you time because of the components that are already written for it.
I recommend QCodo, it's amazing; there are others - CakePHP, Symfony. |
Hasn't this change from 2003 to 2007? There's no longer an excluded paths option. |
It would of course depend on the wiki engine you're talking to. Most likely though, as sblundy says, it would be a security risk to allow free usage of javascript on the wiki page. |
I've found Informatica to be an exceptionally useful data processing tool. The good news is that the more recent versions even allow Java transformations. If you're dealing with terabytes of data, it might be time to pony up for the best-of-breed ETL tools.

It completely depends on the specific Wiki software you are using. The way I've seen work is to host a js file somewhere else and then include with a script tag with a src attribute.

Split the string into runs of letters and numbers, so "foo 12 bar" becomes the list ("foo", 12, "bar"), then use the list as the sort key. This way the numbers will be ordered in numerical order, not alphabetical. |
If you haven't already, try HP Openview trial version, and apart of using SNMP, it also uses ARP tables to figure out your topology. |
I have two suggestions.
1. Perhaps you need to consolidate all your tables. If they all contain the same structure, then why not have one "master" module table, that just adds one new column identifying the module ("A", "B", "C", ....)
If your module tables are mostly the same, but you have a few columns that ... |

Use cvs `-d/cvsroot checkout -d directory project/path/directory`. The first `-d` can be omitted if you set the root with the environment. This is called "shortening the path" and can be avoided with the `-N` option to `checkout`. |
One simple suggestion would be to group controls into panels based on access rights |
CVS is 'tied' to the repository by files in the `.CVS` folder. Each folder is 'tied' individually.
This means you can just check out the full thing (or if you already have the full thing), then cut/paste the `www` directory out to somewhere else, and it will remain linked to the correct CVS location. |

getX() is often the name of an accessor function for member x, similar to your own usage. However, a "getX" accessor is also very often a read-only function, so that it may be surprising in other situations of your code base to see a call to "getX" that modifies X.
So I would suggest, instead of just using a refere... |

I don't think so. A const method is a method that doesn't change the state of the object (i.e. its fields), but you can't assume that given the same input, return value of a const method is determined.

Usually with a VTable, an array of pointers to functions. |
Make a call to a reliable destination, or perhaps a series of calls, ones that should go through and return if the user has an active net connection - even something as simple as a token ping to google, yahoo, and msn, or something like that.

Each object has a vtable pointer that points to an array of member functions. |
