Error: AndroidRuntime android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

I was working on an app about local restaurants in Niagara and had an about window.

Solution:

error
...
private static Context context;
....

MainActivity.context = getApplicationContext(); // this was causing some nasty errors.

correct
MainActivity.context = this;

$("#qfileupload").fileupload is not a function, $("#qfileupload").qtips is not a function

Have you seen this annoying JavaScript error message ?

$("#some_id").someplugin is not a function

I bet you have!

in most cases the plugin is not loaded but when everything is loaded fine then you should check if jquery is loaded more than once.

It turned out that if there are multiple copies of jquery loaded this causes the jquery extensions not to work.

Just lost a few hours troubleshooting this.

How to detect old browsers in PHP and show a obsolete browser notice

put this in a file called common.
Class App_Util {
    function is_old_browser() {
        $old = 0;

        if (!empty($_SERVER['HTTP_USER_AGENT'])) {
            // IE <= 7
            // User Agent: Opera/9.80 (Windows NT 6.1; U; en) Presto/2.10.229 Version/11.61
            if (preg_match('#msie\s+(\d+)\.(\d+)#si', $_SERVER['HTTP_USER_AGENT'], $matches)) {
                if ($matches[1] <= 7) {
                    $old = 1;
                }
            }
            // Firefox <= 7
            // User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
            elseif (preg_match('#Firefox/(\d+)\.(\d+)[\.\d]+#si', $_SERVER['HTTP_USER_AGENT'], $matches)) {
                if ($matches[1] <= 7) {
                    $old = 1;
                }
            }
            // Safari < 5
            // User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534.52.7 (KHTML, like Gecko) Version/5.1.2 Safari/534.52.7
            elseif (preg_match('#Version/(\d+)[\.\d]+ Safari/[\.\d]+#si', $_SERVER['HTTP_USER_AGENT'], $matches)) {
                if ($matches[1] < 5) {
                    $old = 1;
                }
            }
            // opera < 11
            // User Agent: Opera/9.80 (Windows NT 6.1; U; en) Presto/2.10.229 Version/11.61
            elseif (preg_match('#Opera/[\.\d]+.*?Version/(\d+)[\.\d]+#si', $_SERVER['HTTP_USER_AGENT'], $matches)) {
                if ($matches[1] < 11) {
                    $old = 1;
                }
            }
        }

        return $old;
    }
}

How to perform the check
file: block_old_browser.php

<?php if (App_Util::is_old_browser()) : ?>
    <div class="app_old_browser_notice">
        <h2>Old Browser</h2>

Internet Explorer offers/prompts JSON output for download

I playing with jQuery and ajax stuff and tried to test my app in Internet Explorer.

this is the function I have for emitting JSON.
Iinitally, I had Content-Type: application/json but IE 9 started started prompting me to save the file that was called by the Ajax.
Replacing the content type with Content-Type: text/javascript seems to work in IE, Firefox, Opera, Safari.

// slavi: links // links preceeded by space i.e. no http prefix
function json($struct) {
    header('Cache-Control: no-cache, must-revalidate');
    header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
    header('Content-Type: text/javascript'); // IE doesn't like application/json content type
//    header('Content-Type: application/json; charset=utf-8');

    echo json_encode($struct);

    exit;
}

Confusing input boxes for GoDaddy Nameservers During Registration

I know that GoDaddy is a big company but I am still trying to understand how do those people can allow this kind of UI to be live.

I am a programmer and I find it super confusing.
On my domain registration step I find 3 boxes per name server.
what's that ?

there are multiple options and I don't know how to interpret it.

[ns1] [mydomain] [com]

[ns1] [mydomain.com] [____]

[___] [ns1.mydomain.com] [____]

So strange.
