I have been looking for a website up-time monitoring solution for awhile now. I have used a couple of website monitoring services in the past and have been fairly pleased with them. However, this never stops me from continuing to look around for a better option. Fortunately for myself, I recently stumbled across a new service called UptimeRobot. I have been using UptimeRobot for about a month now and am ready to recommend the service.

There are five main items that sold me on the service:

• There is no cost; the service is totally free. The entire feature set is available to you at no cost with no hidden fees. Their blog talks about their commitment to keeping the service free.
• Your websites are monitored in 5 minute intervals. Most website monitoring services offer monitoring in 30 minute intervals for free and only offer more frequent checks at a price.
• You can monitor up to 50 websites. It goes without saying that 50 is plenty of monitors. Who could expect more for free?
• Instant notification of down-time and subsequent up-time with alerts through e-mail, SMS, twitter, and RSS. There is also a feature which allows you to have more than one person receive an alert.
• Standard (http) and secure (https) protocols are supported.

Have you tried UptimeRobot yet? If so, let us know what you think in the comments.

I mentioned in one of my previous posts, ZFDebug – Zend Framework Plugin, that I have really enjoyed developing my personal web projects with Zend Framework. I am still pretty new to it and am constantly learning new tips, tricks, and best practices. Scouring the web for as much information as I can possibly consume, I came across this free online book. Zend Framework: Surviving The Deep End is comprised of ten chapters with three appendices from introducing Zend Framework to installing Zend Framework to developing a blog application with Zend Framework. You can find a full book index on the website.

As I see it there are three main advantages to this book:

1. Both the book itself and the code snippets within the book are freely available online and licensed appropriately. The book content is licensed under a Creative Commons Attribution-Non-Commercial-No Derivative Works 3.0 Unported License and the code is licensed under a New BSD License. You can see the licensing information in Appendix C, part 2 - Licensing.
2. The content is well written, easy to understand, and well designed for beginners like myself. I don't have any first-hand reviews from advanced Zend Framework developers, but I have gone back to this book multiple times while working with Zend Framework on my own projects.
3. The book is open to user comments. This is a really neat idea. Not only are comments available, but you can comment on every paragraph of the book individually. There are a lot of comments out there already, many of which are quite helpful in reaffirming a statement made in the book or offering further information about the subject at hand.

If you are looking for some good help as you work with Zend Framework to develop your web projects like I was, I would recommend giving Zend Framework: Surviving The Deep End a chance. I have really enjoyed it.

I recently decided sto give OpenX a shot for managing my advertisement inventory. I primarily use Google AdSense, but I wanted to be able to rotate through other ads when the opportunities are available. I had played a little bit with OpenX back when it was phpAdsNew but never got too far into a full implementation. Looking at the screenshots, documentation, and features, OpenX looked like a very good option.

After getting the current version (2.8.5) installed, unfortunately, I encountered a problem as soon as I logged in for the first time. After logging in I was directed to a dashboard page, which was one of my key reasons for trying OpenX again, and it failed to load, showing the following error: "Dashboard Error: M2M authentication error – password invalid (code: 823)." (You can also see the screenshot above). Fortunately, there is an extremely easy fix.

After a few Google searches I was able to find out that the error was occurring because I had used Fantastico to install OpenX, and this was not the first time I tried. I had forgotten that I had installed and uninstalled OpenX once before. Because I had installed it once before, it failed to create a valid m2m password the second time OpenX was installed. The invalid m2m password was causing the authentication error on the dashboard page.

The Fix: Simply go to http://(your path to OpenX)/www/admin/regenerate-platformhash.php

It seems too good to be true, but it is really this simple. I followed that one step, and it worked like a charm. The next time I opened the dashboard I was able to see it without any problems. (See screenshot below of working dashboard). I hope this helps!

Adobe is set to release the newest version of its popular software suite, Adobe Creative Suite CS5, on Monday April 12, 2010. There is an online launch event that you can register for. I haven't done a lot of research on CS5, but there are some really cool sneak peek videos showing new features like Puppet Warp and Content-Aware Fill.

If you are interested in some good information regarding CS5, check out http://cs5.org/.

I began using SiteUptime to monitor my blog's up-time a couple of weeks ago; so far I have been quite pleased. I am only using the free version of the service, so I do not get all of the bells and whistles that are offered with the paid accounts; however, I have already been notified of some downtime I had recently on this blog. I received an email and began taking action to get the blog back up.

There are three different accounts available offering different features. You can sign up for a free plan, a premium plan for $5 per month, or an advanced plan for $10 per month. All plans include the following features:

• 4 Monitoring Locations
• Email Alerts
• Monthly Reports
• Online Statistics
• Control Panel
• Web Server (http)
• Email Server (pop3)
• Email Server (smtp)
• FTP Server (ftp)

For more information on what is offered in the different plans, check out SiteUptime's comparison page.

I just wanted to share the link; I found it quite amusing.

I have spent a lot of time recently working with Zend Framework. As I get further into its features and capabilities, the more I enjoy developing websites and web applications with it. While researching ideas and options, I came across ZFDebug, a plugin that adds a debug bar to the bottom of your pages if you are in the "development" environment. The plugin is hosted on Google Code and is licensed under the New BSD License.

At current release (1.5) ZFDebug offers the following features:

• Cache: Information on Zend_Cache and APC.
• Database: Full listing of SQL queries and the time for each.
• Exception: Error handling of errors and exceptions.
• File: Number and size of files included with complete list.
• Html: Number of external stylesheets and javascripts. Link to validate with W3C.
• Memory: Peak memory usage, memory usage of action controller and support for custom memory measurements.
• Registry: Contents of Zend_Registry
• Time: Timing information of current request, time spent in action controller and custom timers. Also average, min and max time for requests.
• Variables: View variables, request info and contents of $COOKIE and $POST

My CSS Menu is one of the coolest websites I've been to in a while. If you are in need of a nice looking CSS menu but don't know where or how to get started, or maybe just don't want to start from scratch then you are in luck; My CSS Menu is your answer.

You can currently choose from 22 different already designed for you CSS menus (I'm sure there are more on the way). They have very basic menus and very advanced menus and everything in between to meet all your needs. While all of these options are great to have it is not by far the best part of the site though. Once you decide on a menu type you have the ability to customize it to meet your exact needs including size, colors, animation effects, and more. This customization turns 22 options into an almost endless amount of different menus.

The CSS editor (see screenshot above) is very fast and easy to use. The GUI is well designed and intuitive. You can preview your changes, save changes, and import saved menus. You can use a designer mode, CSS mode, and HTML mode which feel and look a lot like Adobe Dreamweaver for those of you that are familiar with the product.

Open Flash Chart is a free project that allows you to integrate flash graphs in you website. There is support for all of the commonly used graphs like bar charts, line charts, area charts, and scatter plots. The flash component allows the user to hover over points of the graph and view labels explaining the point (see screenshot above). This feature is what sets Open Flash Chart apart from other chart/graph apps. Check out the website for tutorials and examples. There are other static graphing libraries like Google Charts that are clean and useful but static.

You can download Open Flash Chart and use it under the GNU General Public License. If you need help with implementing it or customizing or using the different libraries you can check the forums.
