  • Palm webOS CSS Targeting Hack?

    - by Tom
    Although it is not good practice, I am looking for a CSS hack to target Palm webOS. The problem is that Safari 3+ is awesome, and I can do some things like gradient background animations on text, but only in Safari. Right now I use @media screen and (-webkit-min-device-pixel-ratio:0) {} and it works like a charm, no Opera, Firefox, or whatever, because if I set the background to the image as I do in Safari they will all be ruined. But Palm's browser is based on webkit, and it uses the rules inside, and Palm's browser doesn't support text backgrounds so all I get is the image moving, no text. I would prefer a CSS hack, but if need be a Javascript one will do.

  • include figure files in latex

    - by Tim
    Hi, I am trying to include jpeg files in latex \includegraphics[width=57.6mm, height=43.2mm]{../../results2/html/zerooneloss_stumps.jpg} With specified the width and height and compiled with pdflatex, however, it produces the error: ! LaTeX Error: Cannot determine size of graphic in ../../results2/html/zerooneloss_stumps.jpg (no BoundingBox). The true size of the image is 576x432 in pixels. Have I specified the size correctly in the latex file? Anyway to use the default setting without need to specify the width and height? If I don't specify the them in the latex file, \includegraphics[]{../../results2/html/zerooneloss_stumps.jpg} I still get the same no BoundingBox error. Thanks and regards!

  • Get entire text of document as a string using javascript

    - by Tom Dignan
    I am developing a firefox extension and ideally would be able to get the whole darn DOM as a string.. forget any data structure. I just want what I see in "view source" in a buffer. I have been checking out javascript references and HTMLDocument etc. with no avail. Ideally I would be able to write to this buffer as well (seems possible i.e. document.writeLn()) I wish there was a document.read()? Am I just a js noob?

  • Encapsulate update method inside of object or have method which accepts an object to update

    - by Tom
    Hi, I actually have 2 questions related to each other: I have an object (class) called, say MyClass which holds data from my database. Currently I have a list of these objects ( List < MyClass ) that resides in a singleton in a "communal area". I feel it's easier to manage the data this way and I fail to see how passing a class around from object to object is beneficial over a singleton (I would be happy if someone can tell me why). Anyway, the data may change in the database from outside my program and so I have to update the data every so often. To update the list of the MyClass I have a method called say, Update, written in another class which accepts a list of MyClass. This updates all the instances of MyClass in the list. However would it be better instead to encapulate the Update() method inside the MyClass object, so instead I would say foreach(MyClass obj in MyClassList) { obj.update(); } What is a better implementation and why? The update method requires a XML reader. I have written an XML reader class which is basically a wrapper over the standard XML reader the language natively provides which provides application specific data collection. Should the XML reader class be in anyway in the "inheritance path" of the MyClass object - the MyClass objects inherits from the XML reader because it uses a few methods. I can't see why it should. I don't like the idea of declaring an instance of the XML Reader class inside of MyClass and an MyClass object is meant to be a simple "record" from the database and I feel giving it loads of methods, other object instances is a bit messy. Perhaps my XML reader class should be static but C#'s native XMLReader isn't static.? Any comments would be greatly appreciated Thanks Thomas

  • JavaScript: Double script tags in Google Analytics tracking code

    - by Tom
    This is more a curiosity question than anything else... Google instructs to add the analytics tracking code as follows: <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try{ var pageTracker = _gat._getTracker("UA-xxxxxx-x"); pageTracker._trackPageview(); } catch(err) {} </script> I'm wondering some JS guru here could tell me why they're separating it into two script tags instead of sticking it all inside one. I know that the top part could be put in the header and the bottom part just before body tag to ensure the page loaded before it's tracked, but I'm wondering if there's something more to it. Anyone who'd know that would likely know how to separate the code into two tags anyway. I'm only asking as this is coming from the Goog and is being used by millions of sites... Thanks

  • How can you connect to a password protected MS Access Database from a Spring JdbcTemplate?

    - by Tim Visher
    I need to connect to a password protected MS Access 2003 DB using the JDBC-ODBC bridge. I can't find out how to specify the password in the connect string, or even if that is the correct method of connecting. It would probably be relevant to mention that this is a Spring App which is accessing the database through a JdbcTemplate configured as a datasource bean in our application context file. Some relevant snippets: from application-context.xml <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="legacyDataSource" /> </bean> <bean id="jobsheetLocation" class="java.lang.String"> <constructor-arg value="${jobsheet.location}"/> </bean> <bean id="legacyDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.legacy.driverClassName}" /> <property name="url" value="${jdbc.legacy.url}"/> <property name="password" value="-------------" /> </bean> from our build properties jdbc.legacy.driverClassName=sun.jdbc.odbc.JdbcOdbcDriver jdbc.legacy.url=jdbc:odbc:Driver\={Microsoft Access Driver (*.mdb)};Dbq\=@LegacyDbPath@;DriverID\=22;READONLY\=true Any thoughts?

  • qtruby, QUiLoader and respond_to?

    - by Tim Sylvester
    I'm writing a simple Qt4 application in Ruby (using qtruby) to teach myself both. Mostly it has gone well, but in trying to use Ruby's "duck typing" I've run into a snag; respond_to? doesn't seem to reflect reality. irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'Qt4' => true irb(main):003:0> require 'qtuitools' => true irb(main):004:0> Qt::Application.new(ARGV) => #<Qt::Application:0xc3c9a08 objectName="ruby"> irb(main):005:0> file = Qt::File.new("dlg.ui") { open(Qt::File::ReadOnly) } => #<Qt::File:0xc2e1748 objectName=""> irb(main):006:0> obj = Qt::UiLoader.new().load(file, nil) => #<Qt::Dialog:0xc2bf650 objectName="dlg", x=0, y=0, width=283, height=244> irb(main):007:0> obj.respond_to?('children') => false irb(main):008:0> obj.respond_to?(:children) => false irb(main):009:0> obj.children => [#<Qt::FormInternal::TranslationWatcher:0xc2a1980 objectName="">, ... As you can see, when I check to ensure that the object I get back from loading the UI file has a children accessor I get false. If call that accessor, however, I get an array rather than a NoMethodError. So, is this a bug or have I incorrectly understood respond_to?? This looks like the problem described here, but I thought I would get an expert opinion before filing a bug against the project.

  • Converting the value from string to integer in a nested dictionary

  • Problem to focus JTextField

    - by Tom Brito
    I have used the approach of the ComponentListener to call focus in JTextField within a dialog, but for this case is just not working, I don't know why. It shows the focus in the text field and fast change to the button. Run and see: import java.awt.Component; import java.awt.GridLayout; import java.awt.event.ComponentEvent; import java.awt.event.ComponentListener; import javax.swing.JDialog; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JPanel; import javax.swing.JPasswordField; import javax.swing.JTextField; public class User { private String username = ""; private String password = ""; public User() { // default constructor } public User(String username, String password) { this.username = username; this.password = password; } /** Create a panel containing the componet and tha label. */ public JPanel createLabeledComponent(JLabel label, Component comp) { GridLayout layout = new GridLayout(2, 1); JPanel panel = new JPanel(layout); panel.add(label); panel.add(comp); label.setLabelFor(comp); return panel; } public void showEditDialog() { JLabel usernameLbl = new JLabel(username); final JTextField usernameField = new JTextField(); usernameField.setText(username); JPanel usernamePnl = createLabeledComponent(usernameLbl, usernameField); JLabel passwordLbl = new JLabel(password); JPasswordField passwordField = new JPasswordField(password); JPanel passwordPnl = createLabeledComponent(passwordLbl, passwordField); Object[] fields = { "User:", usernamePnl, "Password:", passwordPnl }; JOptionPane optionPane = new JOptionPane(fields, JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION, null, null); JDialog dialog = optionPane.createDialog("User Data"); dialog.addComponentListener(new ComponentListener() { public void componentShown(ComponentEvent e) { usernameField.requestFocusInWindow(); } public void componentResized(ComponentEvent e) {} public void componentMoved(ComponentEvent e) {} public void componentHidden(ComponentEvent e) {} }); dialog.setVisible(true); } public static void main(String[] args) { new User().showEditDialog(); } } Any idea how to solve this?

  • Scriptaculous Sortable.create - Can't hook the dragged element

    - by Tom
    When using Sortable.create I can't seem to get the element that is being dragged. Does Sciptaculous not fully implement all Draggable and Droppable features when you use sortable? Given: Sortable.create("sortArea", {scroll:window, onChange:orderLi}); function orderLi(){ console.log(this.draggables.each(function(e){if(e.dragging==true){return e};})); } My console always shows all the array of draggables. How do I only grab the one that is being dragged?

  • jQuery hyperlinks - href value?

    - by Tom
    Hi, On my website I use jQuery to hook the events of elements, namely hyperlinks. As these hyperlinks only perform actions on the current page, and do not lead anywhere, I have been putting a href attribute of "#" in: <a href="#">My Link</a> However in some browsers this causes the page to scroll right to top which is obviously undesirable behaviour. I've tried using a blank href value, or not including one, but then the mouse does not change to the hand cursor upon hovering. What should I put in there?

  • Consecutive Tables in Latex

    - by Tim
    Hi, I wonder how to place several tables consecutively in Latex? The page with the text right before the first table has a little space but not enough for the first table, so the first table is to be placed on the top of the next page, although I use "\begin{table}[!h]" for it. The second table does not fit into the place in the rest of the page of the first table, so I think I might use longtable for it to span the rest of the page and the top of the next page. Similarly, I use longtable for the third table. The latex code is as follows: ... % some text \begin{table}[!h] \caption{Table 1. \label{tab:1}} \begin{center} \begin{tabular}{c c} ... \end{tabular} \end{center} \end{table} \begin{center} \begin{longtable}{ c c } \caption{Table 2. \label{tab:2}}\\ ... \end{longtable} \end{center} \begin{center} \begin{longtable}{ c c } \caption{Table 3. \label{tab:3}}\\ ... \end{longtable} \end{center} ... % some text In the compiled pdf file it turns out that the order of the tables is messed up. The first table is placed behind the second and third one, and the second one spans the page with text before the tables and the next page with the third one following it. I would like to know how I can make the three tables appear consecutively in order, and there are no space left blank between them and between the text and the tables? Or if what I hope is not possible, what is the best strategy then? Thanks and regards! EDIT: Removing [!h] does not make improvement, the first table is still behind the second and the third.

  • virtualenv on Windows: not over-riding installed package

    - by Tom
    My current setup is Python 2.5/ Django 1.1.1 on Windows. I want to start using Django 1.2 on some projects, but can't use it for everything. Which is just the sort of thing I've got virtualenv for. However, I'm running into a problem I've never encountered and it's hard to Google for: installing Django 1.2 into a virtualenv has no effect for me. If I then activate the environment and do python import django django.VERSION I get "1.1.1 Final". Django is installed in the site-packages directory of my environment and the init file in the root shows that it is 1.2. But the environment falls back to 1.1.1, even if I create the environment with the --no-site-packages flag. What am I screwing up?

  • OpenGL pixels drawn with each horizontal pair swapped

    - by Tim Kane
    I'm somewhat new to OpenGL though I'm fairly sure my problem lies in the pixel format being used, or how my texture is being generated... I'm drawing a texture onto a flat 2D quad using a 16bit RGB5_A1 pixel format, though I don't make use of any alpha at this stage. The problem I'm having is that each pair of horizontal pixel values have been swapped. That is... if the pixels positions should be in this order (assume 8x2 image) 0 1 2 3 4 5 6 7 they are instead drawn as 1 0 3 2 5 4 7 6 Or, more clearly from this image (below). Left is what I get... Right is what I should get. . The question is... How have I ended up with this? Is there something wrong with the pixel format? Unlikely since the colours all appear correct, and I would expect all kinds of nasty if it were down to endian-ness. Suggestions greatly appreciated. Update: Turns out the problem was in my source renderer. Interestingly, I've avoided the problem entirely by using 32-bit textures (haven't tried 24-bit at this point).

  • Python raw strings and trailing back slashes.

    - by dash-tom-bang
    I ran across something once upon a time and wondered if it was a Python "bug" or at least a misfeature. I'm curious if anyone knows of any justifications for this behavior. I thought of it just now reading "Code Like a Pythonista," which has been enjoyable so far. I'm only familiar with the 2.x line of Python. Raw strings are strings that are prefixed with an r. This is great because I can use backslashes in regular expressions and I don't need to double everything everywhere. It's also handy for writing throwaway scripts on Windows, so I can use backslashes there also. (I know I can also use forward slashes, but throwaway scripts often contain content cut&pasted from elsewhere in Windows.) So great! Unless, of course, you really want your string to end with a backslash. There's no way to do that in a 'raw' string. In [9]: r'\n' Out[9]: '\\n' In [10]: r'abc\n' Out[10]: 'abc\\n' In [11]: r'abc\' ------------------------------------------------ File "<ipython console>", line 1 r'abc\' ^ SyntaxError: EOL while scanning string literal In [12]: r'abc\\' Out[12]: 'abc\\\\' So one slash before the closing quote is an error, but two slashes gives you two slashes! Certainly I'm not the only one that is bothered by this? Thoughts on why 'raw' strings are 'raw, except for slash-quote'? I mean, if I wanted to embed a single quote in there I'd just use double quotes around the string, and vice versa. If I wanted both, I'd just triple quote. If I really wanted three quotes in a row in a raw string, well, I guess I'd have to deal, but is this considered "proper behavior"?

  • How do you tell if two wildcards overlap?

    Given two strings with * wildcards, I would like to know if a string could be created that would match both. For example, these two are a simple case of overlap: Hello*World Hel* But so are all of these: *.csv reports*.csv reportsdump.csv Is there an algorithm published for doing this? Or perhaps a utility function in Windows or a library I might be able to call or copy?
