Redis

Not a mainstream database, its syntax reminds me of old console programs. Nothing superfluous, only the command, and arguments separated by spaces.

Though it's pronounced RED-iss, I like calling it ruh-DISS.

Unfortunately I haven't found many resources. Here's one:

Android SDK

So far I'm not impressed. Eclipse is unresponsive, and the default installation lacks a file needed for virtual device creation. And installing anything is slow as molasses.

stealth35 saves the day

After some poking around I found that in PHP 5.4, arrays can be written like this:
$array = [
"foo" => "bar",
"bar" => "foo"];
and I tried finding a WAMP supporting PHP 5.4, which led to discovering this PHP version was released in early March.

I "updated" Ampps by replacing its PHP folder with an unzipped 5.4 folder. Other than a few warnings, it worked.

Then, the MongoDB driver refused to work. From Stack Overflow, I found a link to stealth35's compiled driver dll. Now, everything works!

Right now, I'm not liking the PHP driver for MongoDB. Take a look at this example from http://www.php.net/manual/en/mongo.updates.php:

<?php/** suppose documents look like:
* {"username" : "...", "password" : "...", "email" : "..."}
*/
$coll-> update(array("username" => "joe"), array("userId" => 12345,
"info" => array("name" => "joe", "twitter" => "@joe4153", "email" => "..."),
"likes" => array()));

array(" I " => "want my JavaScript back")

Ajax jQuery style

I am trying out the comma-first style for my objects. I got errors many times when I added a new pair to an object list because I didn't add a comma to the last pair.

Although curl gives a more informative message, I cannot get the same information out of statusCode 412.

<html>
<head>
<script type="text/javascript" src="jquerymin.js"></script>
<script type="text/javascript">
function initialize() {
$.ajax({
type: "PUT"
, url: "http://127.0.0.1/couchdb/albums"
, success: function(data) {
alert(data);
}

, statusCode: {
412: function(jqXHR, textStatus, errorThrown) {
alert(textStatus);
}
}
});
}
</script>
</head>
<body onload="initialize()">

</body>
</html>
