  • Python - Find where in string regex match was found?

    - by nb
    I'm currently using regular expressions to search through RSS feeds to find if certain words and phrases are mentioned, and would then like to extract the text on either side of the match as well. For example: String = "This is an example sentence, it is for demonstration only" re.search("is", String) I'd like to know where the is was found so that I can extract and output something like this: 1 match found: "This is an example sentence" I know that it would be easy to do with splits, but I'd need to know what the index of first character of the match was in the string, which I don't know how to find

  • Application to download video from youtube

    - by Nidal Saed
    I making an application to view videos form youtube, and I think it is very easy to write a code to make the user be able download the videos and save it in the documents folder of the application, my questions are: 1) is it legal to do this, and is there any concern of the application being rejected? 2) is it possible to make the user watch the video and when he finish (watched all the video) get this data and save it, (not to download it again since he already watched the video and downloaded it).

  • Sanitize GET query with Apache

    - by Freelancer
    Hello everyone, I see there's a lot of talk here about how to go about sanitizing data. Could it be as simple as adding this rewrite rule to .htaccess? RewriteRule ^([\w\-]+)$ index.php?page=$1 To my understanding this will allow only letters, numbers, _ and - in $1, am I right? If you add to this usage of prepared statements for SQL queries, it should be pretty proof, is that right? Somehow feels like too easy to be true, am I missing something, any ways to firm it up?

  • How to get a random node from a tree?

    - by ooboo
    It looks easy, but I found the implementation tricky. I need that for a simple genetic programming problem I'm trying to implement. The function should, given a node, return the node itself or any of its children such that the probability of choosing a node is normally distributed relative to its depth (so the function should return mostly middle nodes, but sometimes the root itself or the lowest ones - but that's not really necessary if that makes it significantly more complex, if all any node is chosen with equal probability, that's good enough). Thanks

  • Finding C#-style unescaped strings using regular expressions

    - by possan
    I'm trying to write a regular expression that finds C#-style unescaped strings, such as string x = @"hello world"; The problem I'm having is how to write a rule that handles double quotes within the string correctly, like in this example string x = @"before quote ""junk"" after quote"; This should be an easy one, right?

  • JFileChooser select directory but show files

    - by Jeff Storey
    I feel like there should be a simple way to do this but I can't figure it out. I have a JFileChooser that allows the user to select directories. I want to show all the files in the directories to give the user some context, but only directories should be accepted as selections (maybe the Open button would be disabled when a file is selected). Is there an easy way of doing this?

  • buttons and menu items in cocos2d/objective-c

    - by peter61
    In my app, I'd like a method called whenever the user taps the screen (anywhere on the screen). Normally, I'd make a transparent UIButton that covers the whole screen. If I'm using the cocos2d framework, what's the best way to do this? Is it good practice to still use UIButtons? I've been reading about MenuItems but haven't found an easy way to make one giant fully transparent menu item? Thanks.

    - by BenIOs
    I'm writing a program that should display the amount of unread sms, mms, phone calls and emails. It was quite easy to find how to query for sms and phone calls (I used the search on this page) but I have not been able to find out how to query for emails. Is there anyway to find out how many unread emails the user got in their phone?

  • Is there a Mercurial equivalent to gitosis?

    - by fedesilva
    I've used ( and still use ) mercurial and git. I have some repos hosted in a server with gitosis which is great and easy to setup. I am looking for a similar tool for hosting mercurial repos. It must provide minimal acl and ssh access and allow for remote config ( in the style of gitosis's "clone the admin repo and push changes" ). Extra points for automating hgweb config via said tool.

  • Finding where varables have been declared in what file?

    - by robUK
    Hello, GNU Emacs 23.1.1 I am maintaining someones code. There are many files and directories for the headers and source files. I am wondering if there is a easy way to use emacs that when I highlight a variable name I can go straight to where it is declared? Some of the structures I am working in are declared in other header files, rather than go searching for them, I just want to be taken straight to them. Many thanks for any suggestions,

  • Computer Science + CFA

    - by scatman
    I still have one semester to finish my MS in Computer Science, and I am already working for a software development company. I took some accounting courses as electives (accounting 1-2 and finance) and I found them interesting and easy. Is it worth it to do CFA? I don't want to change majors, i.e. I still want to be a developer, but would it help if I did CFA?

  • Centralizing / Abstracting MSSQL Data from Multiple Tables / Databases

    - by davemackey
    If one has a number of databases (due to separate application front-ends) that provide a complete picture - for example a CRM, accounting, and product database - what methods are available to centralize/abstract this data for easy reporting? Essentially, I'm wondering if there is a way to automatically pull data from multiple databases into a central repository that is continuously updated from the three databases and which can be used for reporting? I'm also open to alternative best practice suggestions?

  • How to search a hybrid ASP.NET Intranet site?

    - by user343416
    How would you implement a search facility within an ASP.NET hybrid application? I'm really tempted to start rebuilding our Intranet application using ASP.NET MVC & Web Forms (mainly MVC though). I know how to search the dynamic content from a database, but I'm struggling with the static content in the Views. Surely this should be an easy task with routing and a sitemap.

  • Download files with NSURL

    - by Ishwar
    I am trying to download a list of files from a ftp server using: NSURL *ftpUrl = [NSURL URLWithString:@"ftp://xxx:[email protected]"]; I HAVE to use FTP, so please do not recommend an alternative. I want to know how to get the list of files from the root directory and also navigate inside folders (of FTP server). P.S: I do not think external library would be required to accomplish such an easy task, but if I must, any recommendations would be appreciated. Thank You :)
