  • Vertical positioning of text in table cell

    - by Robert
    When I place an image followed by text in a table cell, the vertical alignment of the text shifts down compared to text in adjacent cells. I tried using a line-height CSS property, but it didn't seem to have an affect. In the following example, I need "123 Description" to be flush with "cell one." Also, there is a space between the image and "123" by default. How can I adjust that - negative margins perhaps? <html <head <style type="text/css" table { border-collapse: collapse; } td { border: thin solid; width: 10em;} /* .adjust-text { line-height: 1.3em; } */ </style </head <body <table <tbody <tr <tdcell one</td <td <img src="small-star.png" / <span class="adjust-text"123 Description</span </td </tr </tbody </table </body </html

  • Python Beautiful Soup .content Property

    - by Robert Birch
    What does BeautifulSoup's .content do? I am working through crummy.com's tutorial and I don't really understand what .content does. I have looked at the forums and I have not seen any answers. Looking at the code below.... from BeautifulSoup import BeautifulSoup import re doc = ['<html><head><title>Page title</title></head>', '<body><p id="firstpara" align="center">This is paragraph <b>one</b>.', '<p id="secondpara" align="blah">This is paragraph <b>two</b>.', '</html>'] soup = BeautifulSoup(''.join(doc)) print soup.contents[0].contents[0].contents[0].contents[0].name I would expect the last line of the code to print out 'body' instead of... File "pe_ratio.py", line 29, in <module> print soup.contents[0].contents[0].contents[0].contents[0].name File "C:\Python27\lib\BeautifulSoup.py", line 473, in __getattr__ raise AttributeError, "'%s' object has no attribute '%s'" % (self.__class__.__name__, attr) AttributeError: 'NavigableString' object has no attribute 'name' Is .content only concerned with html, head and title? If, so why is that? Thanks for the help in advance.

  • jQuery: issues with mouseover event if the element has children

    - by Patrick
    hi, I have the following element: <div id="#block-block-1"> <p>KAREN LANCEL:<br> lancel(at)xs4all.nl<br> phone 0031 (0)624873424</p> <p>HERMEN MAAT:<br> maat(at)xs4all.nl<br> phone 0031 (0)628536885</p> </div> which is supposed to disappear when the mouse is moved out of it (I will ignore now to talk about the fading in event). This is the code to make it fading out: $('#block-block-1').mouseout(function() { $(this).css("display","none"); }); The issue here is that the 'mouseout' event is triggered when the mouse is over the children elements inside my div. And the parent disappears even if the mouse is still inside it.

  • Mac OS X: getting names of changed/written files

    - by Patrick
    I remember having a command line tool on an older Mac OS X version (Tiger?) that told me the name of every file that was written to (or read) by any process on the system. It used fseventd (? or something like that). Is there something like that for the newest Mac OS X (10.6)? It should be run in a terminal window and then I can use the system as normal. Let's say I type cat /etc/passwd, the output of that program would be similar to /bin/cat /etc/passwd I can't use lsof because I can't get the timing right. Is this clear or do you need more information?

  • codeigniter differentiate field names in JOINed tables

    - by Patrick
    Hi, I need to retrieve data from two tables. the first is a list of events, the second is a list of venues. I have a fields with the same name in both tables: events.venue (which is an ID) and venues.venue is the name of the place, say "blues bar". The tables can be joined on events.venue = venues.id. Snippet of my model: $this->db->select('events.*, venues.*'); $this->db->join('venues', 'events.venue = venues.id'); if ($date != 'all') { $this->db->where('date', $date); } if ($keyword) { $this->db->like('description', $keyword); $this->db->or_like('band', $keyword); $this->db->or_like('venue', $keyword); $this->db->or_like('genre', $keyword); } $Q = $this->db->get('events'); if ($Q->num_rows() > 0) { foreach ($Q->result() as $row) { $data[] = $row; } } $Q->free_result(); return $data; Snippet of the View: foreach ($events as $row) { echo "<p>{$row->band} ({$row->genre})<br />"; echo "Playing at: {$row->venue}<br /></p>"; // echoes "blues bar" //more here... } 2 Questions: 1) Why does $row-venue echo venues.venue, instead of events.venue? B) how can I differentiate them? eg. What if I want to echo both events.venue and venues.venue? I can probably do something like "SELECT venues.venue as name_of_the_venue", but how can I do this when I've already selected *?

  • What's the best approach for readonly property

    - by Patrick Parent
    Hi, I'm using a model UserRepository-User The Repository is used to Save and Load the User. I want to be able to set the ID in the Repository, but I don't want it to be access by UI. The User and Repository are found in a Core project, and the UI in a Web. Is there a way to do this, like a modifier for the property, or should I put the ID in the User contructor ? Thanks

  • What's the best way to return different cells depending on position in a UITableView

    - by Robert Conn
    I have a grouped UITableView that has 3 sections and a number of cells in each section that each need to be a different custom cell, with different display requirements. I currently have a large if statement in cellForRowAtIndexPath, with each branch instantiating and returning the appropriate custom cell based on interrogating the indexPath's section and row properties. e.g. if (indexPath.section == 0 && indexPath.row == 0) { // instantiate and return cell A } else if (indexPath.section == 1 && indexPath.row == 2) { // instantiate and return cell B } //etc etc What is best practice for this scenario? A large if statement does the job, but is it the best implementation?

  • Drupal, Views.. how to display views list + complete node, interactively ?

    - by Patrick
    hi, I'm using Views in Drupal to show node teasers. I would like now to show the complete node on the left side of my page, nearby the Views, and update it when the user click on a different teaser (better using AJAX). what's the best method to implement it. I was considering to use a lightbox, but it a bit complex (a lot of complications... such as parsing the content with javascript again.. etc). See screenshot: http://dl.dropbox.com/u/72686/viewsAndNode.png Thanks

  • Recommended book for Sql Server query optimisation

    - by Patrick Honorez
    Even if I have made a certification exam on Sql Server Design and implementation , I have no clue about how to trace/debug/optimise performance in Sql Sever. Now the database I built is really business critical, and getting big, so it is time for me to dig into optimisation, specially regarding when/where to add indexes. Can you recommend a good book on this subject ? (smaller is better :) Just in case: I am using Sql Server 2008. Thanks

  • Calculating collission for a moving circle, without overlapping the boundaries

    - by Robert Vella
    Let's say I have circle bouncing around inside a rectangular area. At some point this circle will collide with one of the surfaces of the rectangle and reflect back. The usual way I'd do this would be to let the circle overlap that boundary and then reflect the velocity vector. The fact that the circle actually overlaps the boundary isn't usually a problem, nor really noticeable at low velocity. At high velocity it becomes quite clear that the circle is doing something it shouldn't. What I'd like to do is to programmitically take reflection into account and place the circle at it's proper position before displaying it on the screen. This means that I have to calculate the point where it hits the boundary between it's current position and it's future position -- rather than calculating it's new position and then checking if it has hit the boundary. This is a little bit more complicated than the usual circle/rectangle collission problem. I have a vague idea of how I should do it -- basically create a bounding rectangle between the current position and the new position, which brings up a slew of problems of it's own (Since the rectangle is rotated according to the direction of the circle's velocity). However, I'm thinking that this is a common problem, and that a common solution already exists. Is there a common solution to this kind of problem? Perhaps some basic theories which I should look into?

  • Drupal, ImageCache module not scaling properly

    - by Patrick
    hi, I've set on imagecache a fixed scale for my images (230 x 150). Upscaling option is unchecked. Successively, I've uploaded new images (original size 230 x 150) but for some reason they are resized: 80 x 52 Instead, if I check the "Allow upscaling" option, the size is correct, but the quality is very bad. So basically, it behaves like if my images are very small, but my original images have the correct size. thanks

  • Get info from multiple files, match it and then display to end user, what is fastest?

    - by Patrick
    Hi, I need to build a website where we display data that is refreshed every 5minutes in a text file with a | separator. I currently use Java to do this. What I do now: I grab the textfile for every request through the website and process it and then display the data to the end user, this works fine, since Java can go through like 5000 lines of data fast, and when I filter it it is still extremely fast. However now the management wants the following: They added 3 textfiles with the | separator to it, and now want me to also read those files and match the information on certain fields, and if there is a match also display that information to the end user. I think soon enough, although Java is fast, I will run into trouble when 10 people want that information and I have to run through 4 total files matching the information. What can I do to make this process super fast? My Creative solutions so far: -Leave it this way, since Java is fast and end users can wait (probably less then 1second) -Have a background process that dumps new data into a MySQL database every 5minutes, since databases are extremely good at getting the same data from multiple tables. Thank you!

  • FLEX: how to better align my Tile component to the puppet (and how to solve roll over out effects) ?

    - by Patrick
    hi, At the moment my Puppets are larger on the left if I add them the <mx:Tile> component (with tags): http://dl.dropbox.com/u/72686/puppets.png how can I move my Tile component to the right ? In order to align with the left border of my puppets ? <mx:Tile id="tagsPopup" width="200" visible="false" > <mx:LinkButton label="Tag1" /> <mx:LinkButton label="Tag2" /> <mx:LinkButton label="Tag3" /> <mx:LinkButton label="Tag4" /> </mx:Tile> <mx:VBox verticalGap="0"> <mx:Image id="puppet" source="@Embed(source='../icons/userIcon.png')" /> <mx:Label id="username" text="Nickname" visible="false" fontWeight="bold" /> </mx:VBox> 2nd Question: I want to add objects on top of the puppets, some of them are visible only when the mouse is over, and they are overlying the ones are permanently visible. How do you suggest to implement it ? I was thinking to add in MXML all visible elements and then use Actionscript to add the fade in fade out components. However I just realize it is quite tricky, because I want the user select for example tag1, tag2 and tag3, with the mouse. Instead now they disappear when the mouse rolls out from the puppet image. Any guideline ? thanks

  • Is there a simple library that will render JSON objects as trees?

    - by Robert Gould
    So, is there a VERY simple library that will render JSON objects as trees? I know that this can be done in many ways (such as YUI), but for debug purposes I'd like to simply be able to view a JSON objects I receive from a server as a tree, nothing fancy (but collapsable tree's would be a bonus). The kind of solution I'm looking for would be something like: <script source="something.js"/> <script> obj ={"hello":"world"} lib.renderJSON("someid",obj); </script> ... <div id="someid"/> Any ideas?

  • Twitter oauth php problems

    - by Patrick Gates
    I'm writing some backend script for a twitter app and heres how it's going On the app you click a button that sends you to login.php on my server which logs into my database connects to twitter with my consumer key and secret: $to = new TwitterOAuth($consumer_key, $consumer_secret); $tok = $to->getRequestToken(); $request_link = $to->getAuthorizeURL($tok); and then writes the token and secret to the database, sets a session equal to the id in the database of the token and secret and then redirects to the "$request_link" You then go through the process of logging in and such on twitter and it redirects you to callback.php on my server Callback.php consists of logging into the database again, getting the new token and secret, and then writing the new token and secret to the database and then prompts you to go back to the app Then on the app, all I'm trying to do is access the basic credentials$to->get('account/verify_credentials') and it keeps coming back "could not authenticate you" What am I doing wrong?? Thank you for all the help :)

  • What method do you use to identify the Aggregate Roots in Domain Drive Design?

    - by Robert
    When applying Domain Driven Design to a project, how do you identify the Aggregate Roots? For example, in a standard E-Commerce website, you might say that the Order is one, and the User is the other. But what if your Users belong to a Company? Does that make your Company the aggregate root? I'm interested in hearing people's approaches to working out the Aggregate roots, and how to identify poorly chosen aggregate roots.

  • FLEX: Hillelcoren - AutoComplete (I cannot use searchText attribute)

    - by Patrick
    hi, I'm using hillelcoren:AutoComplete component (hillelcoren.com/flex-autocomplete) in my Flex application. It is really cool, however the text attribute doesn't work: <hillelcoren:AutoComplete id="filterTag" dataProvider="{ dataManager.retrievedTagsList }" labelField="name" keyUp="filterItems(filterTag.searchText)" /> while for the normal TextInput component it works: <mx:TextInput id="filterTag" width="100%" keyUp="filterItems(filterTag.text)" /> 1) I've tried keyUp="Alert.show(filterTag.searchText)" and I can read the text 2) I've tried filterItems(filterTag.text.toString())... still not working 3) the filterItems function works, because it works with a normal TextInput thanks
