Google Page Speed Service: Your site, served by Google

Google and I both appreciate site speed.  It’s important to your end users, to your hosting, and to your sanity.

There’s a euphoric feeling a web developer gets when his site loads in under 500ms (or even lower).

Google has announced, and launched, the Google Page Speed Service.

It’s new, and by invite only (it seems only to Google Apps customers).  If you don’t have the service you can:

• Test your site’s speed (and it sounds like find out how much better life could be)
• Read all about Page Speed Service (Seems to be called PSS)
• Learn the limitations of the service

jQuery 1.5 Released: AJAX Rewrite, Deferred Objects, jquery.sub(), and Performance

I’ve been snowed in and busy working, but in the last week jQuery 1.5 was released (on January 31, 2011).

You can see the announcement here:

Right on schedule jQuery 1.5 is ready for consumption!

This release has been a long time coming and has been a real team effort. Please take this opportunity to thank members of the jQuery Team and the jQuery bug triage team for their help in getting this release out the door.

Google Code: jQuery Outages and a Fix

I’ve posted 2 articles in the past few weeks regarding Google Code going “down” (rather, the jQuery hosted there wouldn’t work), mostly out of frustration:

• 6/3/2010 – Google Code: Did they break jQuery on some sites?
• 6/18/2010 – Google Code’s jQuery hosting goes Down!

There are many pluses and minuses with regards to CDN usage (more pluses though).  There may be a solution…

Google Code’s jQuery hosting goes Down!

Web developers everywhere must be making double takes.  It’s not our code, it’s Google!

The 2nd time I’ve noticed this in the past 2 weeks, it makes it hard to consider Google Code a reliable host.  Not only do developer’s who did as Google recommended get calls from clients, some of our development time was wasted today trying to track this down (for me it was only a few minutes, but I’m sure other developers will spend hours).

From Google Code:

The AJAX Libraries API provides your applications with stable, reliable, high speed, globally available access to all of the most popular, open source JavaScript libraries. Your application can use our very flexible loader google.load() or direct, path based access to the scripts.

I like the “stable, reliable” part myself.

You can see the last time I complained about this problem.

We can only hope this is for some greater good, and not protecting against more evil.

Annoying.  Especially when I’m busy trying to get code done!

UPDATE: If you need to call jQuery code, use this:

<script type=”text/javascript” src=”http://code.jquery.com/jquery-1.4.2.min.js”></script>
