  • Sqlite3 activerecord :order => "time DESC" doesn't sort

    - by Ole Morten Amundsen
    rails 2.3.4, sqlite3 I'm trying this Production.find(:all, :conditions = ["time ?", start_time.utc], :order = "time DESC", :limit = 100) The condition works perfectly, but I'm having problems with the :order = time DESC. By chance, I discovered that it worked at Heroku (testing with heroku console), which runs PostgreSQL. However, locally, using sqlite3, new entries will be sorted after old ones, no matter what I set time to. Like this (output has been manually stripped): second entry is new: Production id: 2053939460, time: "2010-04-24 23:00:04", created_at: "2010-04-24 23:00:05" Production id: 2053939532, time: "2010-04-25 10:00:00", created_at: "2010-04-27 05:58:30" Production id: 2053939461, time: "2010-04-25 00:00:04", created_at: "2010-04-25 00:00:04" Production id: 2053939463, time: "2010-04-25 01:00:04", created_at: "2010-04-25 01:00:04" Seems like it sorts on the primary key, id, not time. Note that the query works fine on heroku, returning a correctly ordered list! I like sqlite, it's so KISS, I hope you can help me... Any suggestions?

  • With ASP .NET, how do I display a side submenu depending on what user picked from the main menu?

    - by Ole Media
    Hello, I come from PHP side, but I'm in need to develop a site using ASP .NET So far I manage to create a master page. Now I'm dealing with menus and submenus What I'm trying to do is, if the user picks "About Us" from the main menu, under the about us page I want to display a submenu with the options "who we are, what we do, contact us" If the user picks "Our Products" from the main menu, then under the products page I want to display a submenu with the options "product 1, product 2, product 3" Is this possible with only one master page? I read something about menu control but not sure that is what I need. So far I found how to display a sitemap, but not specific sections of a sitemap, if this is the way to do things. Any links, sample code, point of reference will be appreciated. Thanks

    - by Ole Jak
    Where to get streaming (live) video and audio from camera example for Nokia (5800 for ex)? Suppose I want to create some live video streaming service app so I'll have some cool server at the back end. And I know how to do that part. Suppose I have some stand alone app for PCs now I want to go on to mobile devices. So I decided to start from Nokia because I have it and can do with it what I want (Nokia 5800 XpressMusic). So I want to see some sample app grabing audio and video streams from Phone, Synchronizing them, and sending LIVE stream to server. I need any OpenSource sample (JAVA or C or C++) that ll do this or something like this. Where can I get one?
