• How can I catch non valid ASCII characters in Panic Coda?

  - by S.c.

  Sometimes I get errors while coding, because of typing some combination of keys (eg. ALT + SHIFT + SQUARE BRACKET) in a wrong way. So I get Syntax Error in Python, but I can't see where the illegal character is, 'cause Coda do not show it to me. Any solution?

• Error with varchar(max) column when using net.sourceforge.jtds.jdbc.Driver

  - by Rihan Meij

  Hi I have a MS SQL database running (MS SQL 2005) and am connecting to it via the net.sourceforge.jtds.jdbc.Driver. The query works fine for all the columns except one that is a varchar(max). Any ideas how to get around this issues? I am using the jdbc driver to run a data index into a SOLR implementation. (I do not control the database, so the first prize solution would be where I can tweak the SQL command to get the desired results) Thanks

• TicTacToe AI Making Incorrect Decisions

  - by Chris Douglass

  A little background: as a way to learn multinode trees in C++, I decided to generate all possible TicTacToe boards and store them in a tree such that the branch beginning at a node are all boards that can follow from that node, and the children of a node are boards that follow in one move. After that, I thought it would be fun to write an AI to play TicTacToe using that tree as a decision tree. TTT is a solvable problem where a perfect player will never lose, so it seemed an easy AI to code for my first time trying an AI. Now when I first implemented the AI, I went back and added two fields to each node upon generation: the # of times X will win & the # of times O will win in all children below that node. I figured the best solution was to simply have my AI on each move choose and go down the subtree where it wins the most times. Then I discovered that while it plays perfect most of the time, I found ways where I could beat it. It wasn't a problem with my code, simply a problem with the way I had the AI choose it's path. Then I decided to have it choose the tree with either the maximum wins for the computer or the maximum losses for the human, whichever was more. This made it perform BETTER, but still not perfect. I could still beat it. So I have two ideas and I'm hoping for input on which is better: 1) Instead of maximizing the wins or losses, instead I could assign values of 1 for a win, 0 for a draw, and -1 for a loss. Then choosing the tree with the highest value will be the best move because that next node can't be a move that results in a loss. It's an easy change in the board generation, but it retains the same search space and memory usage. Or... 2) During board generation, if there is a board such that either X or O will win in their next move, only the child that prevents that win will be generated. No other child nodes will be considered, and then generation will proceed as normal after that. It shrinks the size of the tree, but then I have to implement an algorithm to determine if there is a one move win and I think that can only be done in linear time (making board generation a lot slower I think?) Which is better, or is there an even better solution?

• Text viewing in a delimited space

  - by Maurizio Reginelli

  I need to visualize a text into a delimited space. If I add a simple TextBlock I have a problem: when the text is longer than the available space, it is cropped at the end. I tried to insert the TextBlock inside a Viewbox: this solution works for a text longer than the available space, but increase the size of the text when it is shorter. Is there a way to reduce the size of the text only when it is longer than the available space?

• Get ant concat to ignore BOM's'?

  - by Breck Fresen

  I have an ant build that concatenates my javascript into one file and then compresses it. The problem is that Visual Studio's default encoding attaches a BOM to every file. How do I configure ant to strip out BOM's that would otherwise appear in the middle of the resulting concatenated file? My googl'ing revealed this discussion which is the exact problem I'm having but doesn't provide a solution: http://marc.info/?l=ant-user&m=118598847927096

• Asp.net library to extract plain text from docx, pptx, xlsx (for search index)

  - by Myster

  Is there a pre-existing library to extract plain text form docx, pptx, and xlsx files? I require this to populate a lucene.net index. I've found this example which extracts text from docx and it seems to work ok. But before building my own solution based on this I was wondering if there's something already available for the other file formats?

• Processing incoming emails on Heroku

  - by Jerry Cheung

  For my side project kwiqi, I use ActionMailer's 'receive' method to process incoming email messages for tracking my expenses. Heroku doesn't have a local mail server running that same code will not work. One solution I've thought of is to periodically hit a controller action that will pull messages from Gmail. Are there other solutions that are reasonable? Is anyone processing incoming emails in Heroku?

• How to get distinct results in hibernate with joins and row-based limiting?

  - by Daniel Alexiuc

  I'm trying to implement paging using row-based limiting (for example: setFirstResult(5) and setMaxResults(10)) on a Hibernate Criteria query that has joins to other tables. Understandably, data is getting cut off randomly; and the reason for that is explained here. As a solution, the page suggests using a "second sql select" instead of a join. How can I convert my existing criteria query (which has joins using createAlias()) to use a nested select instead?

• objective-c iphone XML parsing one element

  - by Marko

  I know that when parsing XML with objective-c most of the time you use NSXMLParser. But what if you only need to read one element. Using NSXMLParser sounds like an overload to me. The issue is that flickr API doesn't use JSON as response when uploading an image. So my response now is: 4638598522 I only need to know the photoid and I like to know what the best solution will be for this.

• iPhone dev: load a file from resource folder

  - by thomax

  I'm writing an iPhone app with a UIWebView which should display various html files I have in the app resource folder. In xcode my project overview, these html files are displayed like this: dirA |---> index.html |---> a1.html |---> a2.html |---> my.css |---> dirB |---> b1.html |---> b2.html |---> dirC |---> c1.html |---> c2.html These resources where added to the project as such: - Checked "Copy items into destination groups folder (if needed)". - Reference type: Default. - Text encoding: Unicode (utf-8). - Recursively create groups for any added folders. The links in my html are relative, meaning they look like this: <a href="a1.html">a2</a> <a href="a2.html">a2</a> <a href="dirB/b2.html">b2</a> <a href="dirC/c1.html">b2</a> In order to display the index.html when the app starts up, I use the following code: NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]; NSURL *url = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [webView loadRequest:request]; This works fine. Following links from the index file also works fine, as long as the html files requested are directly under dirA. If the link followed points to a file in a sub-directory, then didFailLoadWithError will catch the situation and report that the requested file does not exist. Note that [webView loadHtmlString:myHtml]; cannot be part of the solution, as I need back and forward buttons to work in my web view. So the question is: How can I follow a relative link to an html file in a sub directory within my resources? I've been all over stackoverflow and the rest of the tubes for the past few days trying to figure this one out, but nowhere have I come across the solution to this exact problem. Any insight at all would be very, very much appreciated!

• Quote POSIX shell special characters in Python output

  - by ??O?????

  There are times that I automagically create small shell scripts from Python, and I want to make sure that the filename arguments do not contain non-escaped special characters. I've rolled my own solution, that I will provide as an answer, but I am almost certain I've seen such a function lost somewhere in the standard library. By “lost” I mean I didn't find it in an obvious module like shlex, cmd or subprocess. Do you know of such a function in the stdlib?
