  • How to sort by hexadecimals in xslt?

    - by fielding
    Hi, im trying to sort my transformed output by a element which contains a hex value. <xsl:sort select="Generation/Sirio/Code" data-type="number"/> Values are plain old Hex: 00 01 02 ... 0A ... FF but they are getting sorted like that: 0A FF 00 01 02, which indicates the sorting method fails as soon as there are character involved. How can i work around this? Thank you very much!

    - by Timmy
    im using the example from the pylons book orm.mapper(Comment, comment_table) orm.mapper(Tag, tag_table) orm.mapper(Nav, nav_table, polymorphic_on=nav_table.c.type, polymorphic_identity='nav') orm.mapper(Section, section_table, inherits=Nav, polymorphic_identity='section') orm.mapper(Page, page_table, inherits=Nav, polymorphic_identity='page', properties={ 'comments':orm.relation(Comment, backref='page', cascade='all'), 'tags':orm.relation(Tag, secondary=pagetag_table) }) i am mostly copying from this, but is there a simple way have a default Page that gets referenced, but if users requests a change, create a new Page object? thanks i want something similar to this class DefaultPage(Page): __init__(self): self.a = a self.b = b self.c = c orm.mapper(DefaultPage, None, inherits=Nav, yada yada )

  • Threadpool with pasistant worker instances

    - by Matt Smokey-waters Holmes
    So basically what im trying to do is queue up tasks in a thread pool to be executed as soon as a worker becomes free, i have found various examples of this but in all cases the examples have been setup to use a new Worker instance for each job, i want persistent workers. Im trying to make a ftp backup tool, i have it working but because of the limitations of a single connection it is slow. What i ideally want to do is have a single connection for scanning directories and building up a file list then four workers to download said files. Here is an example of my worker /** * FTP Worker */ public class Worker implements Runnable { protected FTPClient _ftp; // Connection details protected String _host = ""; protected String _user = ""; protected String _pass = ""; // worker status protected boolean _working = false; public Worker(String host, String user, String pass) { this._host = host; this._user = user; this._pass = pass; } // Check if the worker is in use public boolean inUse() { return this._working; } @Override public void run() { this._ftp = new FTPClient(); this._connect(); } // Download a file from the ftp server public boolean download(String base, String path, String file) { this._working = true; boolean outcome = true; //create directory if not exists File pathDir = new File(base + path); if (!pathDir.exists()) { pathDir.mkdirs(); } //download file try { OutputStream output = new FileOutputStream(base + path + file); this._ftp.retrieveFile(file, output); output.close(); } catch (Exception e) { outcome = false; } finally { this._working = false; return outcome; } } // Connect to the server protected boolean _connect() { try { this._ftp.connect(this._host); this._ftp.login(this._user, this._pass); } catch (Exception e) { return false; } return this._ftp.isConnected(); } // Disconnect from the server protected void _disconnect() { try { this._ftp.disconnect(); } catch (Exception e) { /* do nothing */ } } } and basically i want to be able to call Worker.download(...) for each task in a queue whenever a worker becomes available without having to create a new connection to the ftp server for each download Any help would be appreciated as iv'e never used threads before and I'm going round in circles at the moment

  • Sort Strings by first letter [C]

    - by Blackbinary
    I have a program which places structures in a linked list based on the 'name' they have stored in them. To find their place in the list, i need to figure out if the name im inserting is earlier or later in the alphabet then those in the structures beside it. The names are inside the structures, which i have access to. I don't need a full comaparison if that is more work, even just the first letter is fine. Thanks for the help!

  • Why is cakephp form input stored in $this->data and POST data stored in $this->params['form'] ?

    - by spudnik1979
    the cakephp rest tutorial says that post data should be in $this-data, but I am finding that it is not, but instead inside $this-params['form'] However, when using cakephp form helper in a view, the data is in $this-data. Am I correct to have to check both locations in my controller? It just seems a bit of a waste of extra code. Shouldnt the data appear in one place for whether it came from a rest rest requestor or Cakephp form post? ps im using cakephp 1.3

  • Random number from a range in a Bash Script

    - by Jack
    Hi, I need to generate a random port number between 2000-65000 from a shell script. The problem is $RANDOM is only a 16bit number, so im stuck! PORT=$(($RANDOM%63000+2001)) would work nicely if it wasn't for the size limitation. Does anyone have an example of how I can do this, maybe by extracting something from /dev/urandom and getting it within a range? Thanks.

  • inputAccessoryView not hide the view when -resignFirstResponder?

    - by Sam Jarman
    I have attached a toolbar with a UITextField and UIButton to the keyboard when it becomes the first responder via the user taping inside the textfield textField.inputAccessoryView = theToolbar; Problem is, the toolbar disappears when the keyboard is dismissed, thus preventing any further input. Any ideas on how to make the toolbar go back to the bottom of the screen rather than off it completely? I'm thinking a delegate method might help but Im really not too sure. It seems once the inputAccessoryView always the inputAccessoryView :( Cheers

  • CSS- removing horizontal space in list menu using display inline property

    - by Kayote
    Hi All, Im new to CSS and have a set target of learning & publishing my website in CSS by the end of the month. My question: Im trying to build a CSS horizontal menu with hover drop downs, however, when I use the 'display: inline' property with li (list) items, I get horizontal spaces between the li (list) items in the bar. How do I remove this space? Here is the html: <div id="tabas_menu"> <ul> <li id="tabBut0" class="tabBut">Overview</li> <li id="tabBut1" class="tabBut">Collar</li> <li id="tabBut2" class="tabBut">Sleeves</li> <li id="tabBut3" class="tabBut">Body</li> </ul> </div> And here is the CSS: #tabas_menu { position: absolute; background: rgb(123,345,567); top: 110px; left: 200px; } ul#tabas_menu { padding: 0; margin: 0; } .tabBut { display: inline; white-space: list-style: none; background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(rgba(255,142,190,1)),to(rgba(188,22,93,1))); background: -moz-linear-gradient(top, rgba(255,142,190,1), rgba(188,22,93,1)); font-family: helvetica, calibri, sans-serif; font-size: 16px; font-weight: bold; line-height: 20px; text-shadow: 1px 1px 1px rgba(99,99,99,0.5); -moz-border-radius: 0.3em; -moz-box-shadow: 0px 0px 2px rgba(0,0,0,0.5); -webkit-border-radius: 0.3em; -webkit-box-shadow: 0px 0px 2px rgba(0,0,0,0.5); padding: 6px 18px; border: 1px solid rgba(0,0,0,0.4); margin: 0; } I can get the space removed using the 'float: left/right' property but its bugging me as to why I cannot achieve the same effect by just using the display property.
