I want to store the data returned by $_SERVER["REMOTE_ADDR"] in PHP into a DB field, pretty simple task, really. The problem is that I can't find any proper information about the maximum length of the textual representation of an IPv6 address, which is what a webserver provides through $_SERVER["REMOTE_ADDR"]. I'm not interested in con...
Hi there, I maintain an application which, during the course of two years, has constantly required new hardware to be even usable, due to the amount of new users / new data inserted. However, justifying the investiment is sometimes very hard to do. I started to wonder - how can I establish the maximum number of users a web application...
One of the limitations of ASP.NET 2.0 was that PathInfo was limited to 255 characters. Is that limit a problem in ASP.NET MVC urls, or is there any sort of length limit with ASP.NET MVC routing urls? ...
I have a dictionary: keys are strings, values are integers. Example: stats = {'a':1000, 'b':3000, 'c': 100}. I'd like to get 'b' as an answer, since it's the key with a higher value. I did the following, using an intermediate list with reversed key-value tuples: inverse = [(value, key) for key, value in stats.items()] print ma...
I am running Windows XP as a file server to 8 machines running real time applications. Three of the machines, also running XP, will open upwards of one thousand files each (and keep them open).

I am programming a server and it seems like my number of connections is being limited since my bandwidth isn't being saturated even when I've set the number of connections to "unlimited." How can I increase or eliminate a maximum number of connections that my ubuntu linux box can open at a time? Does the OS limit this, or is it the rou...
The Java Collections.max takes only a collection of a sortable object. However since the collection is not necessarily sorted, I don't see any reason not to implement the same max function for iterable types. Is there a max method for Iterable<T extends Comparable<? super T>> in java's standard library? ...
I'm learning about delegates and think I may have found a use for one. Basically what I have is a series of string properties that take in a minimum value and a maximum value, like so: string weightInvalid(min as int32, max as int32) There are several messages like this, all with unique messages but all sharing the same signature of ...
