• HTML, CSS: how can I merge these divs in order to use float:left property on their children ?

  - by Patrick

  hi, I've 2 sets of thumbnails and in each set I'm displaying them one nearby each other in 4 columns using float:left. I would like to "merge" the 2 sets (but I cannot change the html code) because I want the thumbnails of the second set floating right after the last thumbnail of the first set. In other terms, if in the last row there are only 2 thumbnails and the last 2 columns are empty, the thumbnails of the second set should fill the empty columns of the last row of the first set. This is the code... <div class="field field-type-filefield field-field-image"> <div class="field-items"> <div class="field-item odd"> <a rel="lightbox[field_image][First image&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;/lancelmaat/content/stalkshow&quot; id=&quot;node_link_text&quot; class=&quot;active&quot;&gt;View Image Details&lt;/a&gt;]" href="http://localhost/lancelmaat/sites/default/files/files/projects/Stalkshow/images/LPrisPetjong.jpeg" class="lightbox-processed"><img width="89" height="89" title="" alt="First image" src="http://localhost/lancelmaat/sites/default/files/imagecache/galleryImage/files/projects/Stalkshow/images/LPrisPetjong.jpeg"></a> </div> <div class="field-item even"> <a rel="lightbox[field_image][Second image&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;/lancelmaat/content/stalkshow&quot; id=&quot;node_link_text&quot; class=&quot;active&quot;&gt;View Image Details&lt;/a&gt;]" href="http://localhost/lancelmaat/sites/default/files/files/projects/Stalkshow/images/SeoulLEDScreen2a.jpeg" class="lightbox-processed"><img width="89" height="89" title="" alt="Second image" src="http://localhost/lancelmaat/sites/default/files/imagecache/galleryImage/files/projects/Stalkshow/images/SeoulLEDScreen2a.jpeg"></a> </div> <div class="field-item odd"> <a rel="lightbox[field_image][Third image&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;/lancelmaat/content/stalkshow&quot; id=&quot;node_link_text&quot; class=&quot;active&quot;&gt;View Image Details&lt;/a&gt;]" href="http://localhost/lancelmaat/sites/default/files/files/projects/Stalkshow/images/SeoulSKT6.jpeg" class="lightbox-processed"><img width="89" height="89" title="" alt="Third image" src="http://localhost/lancelmaat/sites/default/files/imagecache/galleryImage/files/projects/Stalkshow/images/SeoulSKT6.jpeg"></a> </div> </div> <!-- second set --> <div class="field field-type-filefield field-field-video"> <div class="field-items"> <div class="field-item odd"> <a rel="lightbox[field_video][Video Number 1&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;/lancelmaat/content/stalkshow&quot; id=&quot;node_link_text&quot; class=&quot;active&quot;&gt;View Image Details&lt;/a&gt;]" href="http://localhost/lancelmaat/sites/default/files/files/projects/Stalkshow/videos/StalkSeoul8d1Mbps.flv" class="lightbox-processed"><img title="" alt="Video Number 1" src="http://localhost/lancelmaat/sites/default/files/imagecache/galleryVideo/files/projects/Stalkshow/videos/StalkSeoul8d1Mbps.flv"></a> </div> <div class="field-item even"> <a rel="lightbox[field_video][Video Number 2&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;/lancelmaat/content/stalkshow&quot; id=&quot;node_link_text&quot; class=&quot;active&quot;&gt;View Image Details&lt;/a&gt;]" href="http://localhost/lancelmaat/sites/default/files/files/projects/Stalkshow/videos/stalkshowdvd21Mbps.flv" class="lightbox-processed"><img title="" alt="Video Number 2" src="http://localhost/lancelmaat/sites/default/files/imagecache/galleryVideo/files/projects/Stalkshow/videos/stalkshowdvd21Mbps.flv"></a> </div> <div class="field-item odd"> <a rel="lightbox[field_video][Video Number 3&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;/lancelmaat/content/stalkshow&quot; id=&quot;node_link_text&quot; class=&quot;active&quot;&gt;View Image Details&lt;/a&gt;]" href="http://localhost/lancelmaat/sites/default/files/files/projects/Stalkshow/videos/StalkShowMoscow1Mbps.flv" class="lightbox-processed"><img title="" alt="Video Number 3" src="http://localhost/lancelmaat/sites/default/files/imagecache/galleryVideo/files/projects/Stalkshow/videos/StalkShowMoscow1Mbps.flv"></a> </div> </div> </div> How can I merge these divs in order to use float:left property on their children ? thanks

• How to build this encryption system that allows multiple users/objects.

  - by Patrick

  Hello! I am trying to figure out how to create an optimal solution for my project. I made this simple picture in Photoshop to try to illustrate the problem and how i want it (if possible). Illustrative image Ill also try to explain it based on the picture. First off we have a couple of objects to the left, these objects all get encrypted with their own encryption key (EKey on the picture) and then stored in the database. On the other side we have different users placed into roles (one user can be in a lot of roles) and the roles are associated with different objects. So one person only has access the to the objects that the role provides. So for instance Role A might have access to Object A and B. Role B have access only to Object C and Role C have access to all objects. Nothing strange in that, right? Different roles have different objects that they can access. Now to the problem part. Each user has to login with his/her username/password and then he/she gets access to the objects that his/her roles provide. All the objects are encrypted so she needs to get a decryption key somehow. I don't want to store the encryption key as a text string on the server. It should be, if possible, decrypted using the users password (along with the role) or similar. That way you have to be a user on the server in order to decrypt an object an to work with it. I was thinking about making a public/private key encryption system, but i am kinda stuck on how to give the different users the decryption key to the objects. Since i need to be able to move users to and from roles, add new users, add new roles and create/delete objects. There will be one administrator that then adds some data to allow the users in that role to get the decryption key to decrypt the object. Nothing is static and i am trying to get a picture of how this can be built or if there is a far better solution. The only criteria are: -Encrypted objects. -Decryption key should not be stored as text. -Different users have access to different objects. -Does NOT have to have roles.

• Open Source projects that use agile methods or have tried them

  - by Patrick Cornelissen

  I'm preparing a short talk for a conference in august and I'm looking for open source projects that are using agile methods internally or have tried them in the past. My goal is to talk about the things that work well and what won't work and promote the agile methods a little bit, because I think certain agile techniques are a good fit, but don't seem to be that common in real development. So does anyone know projects that have tried agile methods and techniques before? I'd like to contact them for a few questions.

• Going from web browser to web request

  - by Patrick

  I am working on a program that automates tasks in a browser like entering text, clicking, etc and right now everything is working fine when using the Web Browser tool in Visual Studio 2010. What I'd like to know is how should I approach converting all of this so I can use send requests instead of the browser? I heard its a lot more efficient and a lot better if you are going to be using multi threading but I have so much code that already works now and am not sure how I should do this without scraping quite a bit of it.

• Oracle Query Optimization: Why is My Second Query Faster?

  - by Patrick Cuff

  I was having some performance issues with an Oracle query, so I downloaded a trial of the Quest SQL Optimizer for Oracle, which made some changes that dramatically improved the query's performance. I'm not exactly sure why the recommended query had such an improvement; can anyone provide an explanation? Before: SELECT t1.version_id, t1.id, t2.field1, t3.person_id, t2.id FROM table1 t1, table2 t2, table3 t3 WHERE t1.id = t2.id AND t1.version_id = t2.version_id AND t2.id = 123 AND t1.version_id = t3.version_id AND t1.VERSION_NAME <> 'AA' order by t1.id Plan Cost: 831 Elapsed Time: 00:00:21.40 Number of Records: 40,717 After: SELECT /*+ USE_NL_WITH_INDEX(t1) */ t1.version_id, t1.id, t2.field1, t3.person_id, t2.id FROM table2 t2, table3 t3, table1 t1 WHERE t1.id = t2.id + 0 AND t1.version_id = t2.version_id + 0 AND t2.id = 123 AND t1.version_id = t3.version_id + 0 AND t1.VERSION_NAME || '' <> 'AA' AND t3.version_id = t2.version_id + 0 order by t1.id Plan Cost: 686 Elapsed Time: 00:00:00.95 Number of Records: 40,717 Questions: Why does re-arranging the order of the tables in the FROM clause help? Why does adding + 0 to the WHERE clause comparisons help? Why does || '' <> 'AA' in the WHERE clause VERSION_NAME comparison help? Is this a more efficient way of handling possible nulls on this column?

• Drupal: what's the easiest way to let my customer to upload video thumbnails and associate them to v

  - by Patrick

  hi, my customer wants a gallery of videos and images (small thumbnails) and if you click on one of them you can see the picture / video in the overlaying lightbox). Now, I cannot install auto-generating video thumbnails because I don't have access to ffmpeg module on the server. I can only allow my customer to upload these thumbnails by himself. I'm using image and video CCK fields for each node to allow my customer images and videos. However I dunno how should I let him upload thumbnails for his videos. Should I create an additional Image CCK field for this ? Consequently, I should somehow associate the videos with the images in the design and my customer should pay attention to place them in the same order.. this is not very nice solution, but it is the only one that came to my mind so far. Furthermore, I'm using the lightbox I should somehow ignore the video thumbnails and display the videos instead... some tips ? Thanks

• SqlAlchemy hangs after adding record in MS SQL

  - by Patrick

  I'm running SQLAlchemy on Jython and trying to connect to a MS SQL database using jTDS with windows authentication. I can query and delete just fine but when I try to insert new values it will hang when I commit. int 'before add' session.add(newVal) print 'after add' session.commit() print 'after commit' I see the first two print statements but not the last. My CPU maxes out and I can't even query the table directly using the MS SQL Management Studio. When I kill the Jython java process I can query again but the new values haven't been added. Strangely enough I can insert values directly using an SQL command: insert_sql = "INSERT INTO my_table (my_value) VALUES ('test_value')" session.execute(insert_sql) session.commit() Any ideas what I'm doing wrong?
