    THE FUTURE OF SOCIAL NETWORKING
    
    0. Introduction.
    
    Almost three years ago, I started the Appleseed Project as a way to start experimenting with the idea of distributed social networking. Armed with enough hubris and naivete to think I could build it alone, I coded and coded until I got to the point I am now: With a project that stands at around 75% complete, it functions as a sort of proof-of-concept for distributed social networking in general. I've learned a lot, however, about the technological hurdles and impact that a truly open and distributed social networking platform could provide.
    
    I'm writing this as a way to present my ideas and what I've learned in the hopes that an open and distributed solution becomes the direction that social networking takes. Although I would be happiest to see Appleseed succeed, I'd be excited to see any open and distributed social networking solution be adopted and replace the walled gardens that currently dot the internet landscape.

82. hosting question
    

    Date: 02/21/08     Keywords: php, mysql, database, sql, hosting

    i have a new client that moved their site from a good but expensive hosting company to a not so good but inexpensive one. the reason was just price. the expensive one was $300 a month, the inexpensive $100 a year. their site is written in php with a mysql database. they are using about 7.5 megs of their database. the problem, of course, is performance: response is ridiculously slow, they are having form problems, et al. now my question. does anyone here know of any decently good hosting companies that i could recommend to my client? they need a switch, but i don't think they want to go back to the one that is $300 a month. usually i deal with very small sites, so i don't know any myself that can manage all this data. thanks for any help you guys can provide, this community is great :o)

83. Comparing Data
    

    Date: 02/17/08     Keywords: database

    I have two arrays. one is data from a database, one is data from a form. If the data in the two arrays are the same, meaning no changes were made to the form, then I want to know so that a database update is not needed. If the data are different, then I want to not only update the database, but mark the time and date of the new update.
    
    Here's what I've come up with:
    $difference=array_diff($formdata, $dbdata);
    $num_diff=count($difference);
    if ($num_diff!=0){ update Database & set new date_updated }
    
    Might there be a more elegant way to do this?

85. PHP Categories?
    

    Date: 02/16/08     Keywords: php, web

    Question. I'm trying to make a website. I already have the PHP for the header, footer, etc. I'm trying to find the script that involves making like categories for the pages. An example is THIS SITE. When you click on her links in the center, the URL becomes:
    
    http://sawyoucry.net/you-download.php?page=brush
    
    How do I go about of doing this? I hope this makes sense.

86. breadcrumbs
    

    Date: 02/14/08     Keywords: browser, web, yahoo

    Hi.. I have to add breadcrumbs to my company's... My first thought is to write a script that will create the links dynamically.
    
    Do you guys have any experience or input regarding implementing a breadcrumb script/solution before I get started?
    
    Thanks
    
    For reference: Breadcrumbs
    
    "There are 3 types: path, attribute, and location. The location breadcrumb is the one most commonly seen. It is a visual display or a page's location within a site. For example, Yahoo! uses location breadcrumbs when it shows you that the page you are on is categorized:
    
    Health>Children>Bed Wetting>Treatment>Cleaning Up
    
    With this, users can see where the page they are on is located in the hierarchy of the site. A 2003 study by Rogers and Chaparro reported is Usability News asked the big question: does Breadcrumb navigation positively affect a user's experience?
    
    There has only been limited research on breadcrumb navigation. However, the studies that have been performed have shown that breadcrumb navigation makes site navigation simpler and more efficient (Bowler, et al. 2001; Maldaonado & Resnick, 2002). In 2003 Bonnie Lida, Spring Hull, and Katie Pilcher examined if study participants would use breadcrumb navigation when given the task of finding several items on a website. They also studied what other methods the subjects chose to use, such as the browser back button or search fields. They hypothesized that breadcrumb navigation was more useful for browsing than for searching for specific terms."

87. nl2br and strip_tags
    

    Date: 02/13/08     Keywords: php, yahoo

    i'm still fairly new to php, so this questions may be pretty obvious.
    
    i'm trying to allow strong, em, and a tags to pass through, but i also want to keep the breaks. all is fine with strong and em, but a's attributes show through. when i get rid of nl2br, everything works, but then i lose my breaks. here is my code:
    
    $post = strip_tags($post, '');
    $post = nl2br($post);
    
    the link looks like this when it outputs:
    
    href="http://www.yahoo.com">click here
    
    a is missing, but the href shows through. link hovers, but of course, it doesn't take you anywhere.
    
    thanks in advance!

89. Form-Generated Image..?
    

    Date: 02/11/08     Keywords: php, google

    Hello; I'm new to this comm and fairly new to php. I'm very sorry if this is a ridiculously stupid question, but I'm not sure where to start with this (and Google/PHP's help articles are no use).
    
    I basically just want to create something like this - where you fill in a form and an image is generated based on your responses/entries. (Although I'd like to do one mimicking a Facebook profile, since Livejournal refuses to allow div/style commands on user bios.)
    
    I promise I'm not a simpleton and I'm not asking to be walked through the whole thing - just an idea where to start (some sample code would be marvellous) would be lovely.
    
    Thank you very much in advance!

90. low-cost logging?
    

    Date: 02/11/08     Keywords: no keywords

    I've been trying to find a low-cost (memory/time) way of logging application events/data and the one idea that came to me was using something like
    file_get_contents("http://inside.my.network.local/logthis/?u=unixTimestamp&i=machineID&l=levelCode&m=escapedMessage&uid=userID")  that way I could use a python server built just to handle message logging.  My only thought, is there a better (non-blocking) way, perhaps with curl, embedding all the data as Post instead of Get variables and setting the timeout to something low like 5MS max.

91. Looping through data, creating table
    

    Date: 02/08/08     Keywords: php, html

    A client needs a table of data displayed as follows:
    
    

    
    
       
       
       
    
    
       
       
       
    
    
       
       
       
    
    
    
       
       
       
    
    
       
       
       
    
    
       
       
       
    
    

    Title 1	Title 2	Title 3
    image 1	image 2	image 3
    Desc 1	Desc 2	Desc 3
    Title 4	Title 5	Title 6
    image 4	image 5	image 6
    Desc 4	Desc 5	Desc 6

    
    

    
    The data is stored in an array, so I am looping through results.  How do I create a table with this exact layout?  The key is the title, image and desc need to be level on each row.  The client did not like everything put in one cell, since the images & titles were different sizes & lengths. 
    
    I was using this
    
    

        foreach ($array_clips as $clip => $data)
        {
            if ($c==0)
            {
                $html .= "

$title
