• Asp.net mvc small amount data storage

  - by Trimack

  Hi there, I am writing some learning tests (i.e. what's the answer for...; choose correct options...). Now my question is, how should I store them. SQL db seems quite an overkill, but I really don't know what would be the best choice if I wanted to select random subset of questions etc. Perhaps some simple xml files? Thanks for advice.

• Using a regex to match IP addresses in Python

  - by MHibbin

  I'm trying to make a test for checking whether a sys.argv input matches the regex for an IP address... As a simple test, I have the following... import re pat = re.compile("\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}") test = pat.match(hostIP) if test: print "Acceptable ip address" else: print "Unacceptable ip address" However when I pass random values into it, it returns "Acceptable ip address" in most cases, except when I have an "address" that is basically equivalent to \d+ Any thoughts welcome. Cheers Matt

• Whats a valid strategy for a secure image upload from a flash client?

  - by WillyCornbread

  Hi all - I'm creating a flash application that will post images to a url for saving to disk/display later. I was wondering what are some suggested strategies for making this secure enough so that the upload is verified as coming from the application and not just some random form post. Is it reliable enough to check referring location realizing that I don't need bulletproof security, or perhaps setting authentication headers is a better strategy even though it seems unreliable from what I have read. Thanks for any advice - b

• How to resize a UIPresentationFormSheet?

  - by Sheehan Alam

  I am trying to display a modal view controller as a UIPresentationFormSheet. The view appears, but I can't seem to resize it. My XIB has the proper height & width, but it seems to get overridden when I call it like this: composeTweetController = [[ComposeTweet alloc] initWithNibName:@"ComposeTweet" bundle:nil]; composeTweetController.modalPresentationStyle = UIModalPresentationFormSheet; [self presentModalViewController:composeTweetController animated:TRUE]; Any thoughts? I am using the iPhone SDK 3.2 beta 4

• Is 23,148,855,308,184,500 a magic number, or sheer chance?

  - by Roddy

  News reports such as this one indicate that the above number may have arisen as a programming bug. A man in the United States popped out to his local petrol station to buy a pack of cigarettes - only to find his card charged $23,148,855,308,184,500. That is $23 quadrillion (£14 quadrillion) - many times the US national debt.* In hex it's $523DC2E199EBB4 which doesn't appear terribly interesting at first sight. Anyone have any thoughts about what programming error would have caused this?

  - by Jeff

  I'm seeking opinion on this.

• single line vs multi-line CSS formatting

  - by pixeltocode

  hi...though it's debatable, i've heard majority of CSS developers prefer multi-line because of the ease at which a property can be found within the CSS file. But doesn't this make the CSS file bigger and less readable on the whole? I think single-line lets you scan the CSS file much faster. Any thoughts?

• C# Parsing html for general use?

  - by Wardy

  What is the best way to take a string of html and turn it in to something useful? Essentially if i take a url and go get the html from that url in .net i get a response but this would come in the form of either a file or stream or string. What if i want an actual document or something I can crawl like an xmldocument object? I have some thoughts and an already implemented solution on this but I am interested to see what the community thinks about this.

• Naming member functions/methods with a single underscore, good style or bad?

  - by Extrakun

  In some languages where you cannot override the () operator, I have seen methods with a single underscore, usually for 'helper' classes. Something likes this: class D10 { public function _() { return rand(1,10); } } Is it better to have the function called Roll()? Is a underscore fine? After all, there is only one function, and it removes the need to look up the name of the class. Any thoughts?

• Generate RTT values

  - by Jean Gauthier

  Hi all, I'm writing a Java applet where I should be able to simulate a connection between two hosts. Hence I have to generate packet round-trip times at random. These RTTs can go from ~0 to infinity, but are typically oscillating around some average value (i.e. an extremely large or small value is very improbable but possible). I was wondering if anyone had an idea of how I could do this? Thanks in advance

• How can I have a web link perform an action in a specific desktop application?

  - by John

  The specific situation is I have a .zip file that I want to open with a certain application. However, I don't want all ZIP files associated with that application. I think the answer is that instead of saying, "download this zip file, and open it with application X" I could have the browser basically go well my desktop application to go fetch it on its own (the same way directives like itunes: mailto: or aim: do things like launch the itunes store, add buddies, etc). Thoughts?

• What is the best programming paper you have read?

  - by SDReyes

  I think that papers are a great information source. they generally tend to be built upon other experts investigations, and generally are short enough to transmit you great ideas in a short coffee read. But I don't really have read many papers in this area. So I would like to start soon and I'll be glad to hear your thoughts. So I wonder what have been the best programming paper you have read?

• Dynamic Multiple Choice (Like a Wizard) - How would you design it? (e.g. Schema, AI model, etc.)

  - by henry74

  This question can probably be broken up into multiple questions, but here goes... In essence, I'd like to allow users to type in what they would like to do and provide a wizard-like interface to ask for information which is missing to complete a requested query. For example, let's say a user types: "What is the weather like in Springfield?" We recognize the user is interested in weather, but it could be Springfield, Il or Springfield in another state. A follow-up question would be: What Springfield did you want weather for? 1 - Springfield, Il 2 - Springfield, Wi You can probably think of a million examples where a request is missing key data or its ambiguous. Make the assumption the gist of what the user wants can be understood, but there are missing pieces of data required to complete the request. Perhaps you can take it as far back as asking what the user wants to do and "leading" them to a query. This is not AI in the sense of taking any input and truly understanding it. I'm not referring to having some way to hold a conversation with a user. It's about inferring what a user wants, checking to see if there is an applicable service to be provided, identifying the inputs needed and overlaying that on top of what's missing from the request, then asking the user for the remaining information. That's it! :-) How would you want to store the information about services? How would you go about determining what was missing from the input data? My thoughts: Use regex expressions to identify clear pieces of information. These will be matched to the parameters of a service. Figure out which parameters do not have matching data and look up the associated question for those parameters. Ask those questions and capture answers. Re-run the service passing in the newly captured data. These would be more free-form questions. For multiple choice, identify the ambiguity and search for potential matches ranked in order of likelihood (add in user history/preferences to help decide). Provide the top 3 as choices. Thoughts appreciated. Cheers, Henry
