The Solution
1. Download the wp-cache-phase1.php in /blog_home/wp-content/plugins/wp-cache/ from your web server.
2. Edit the file by finding the lines:
foreach ($meta->headers as $header) {
header($header);
}
3. Replace these lines with the following:
foreach ($meta->headers as $header) {
if (strpos($header, ‘Last-Modified:’)===FALSE) {
header($header);
} else {
// do nothing - makes GoDaddy angry
}
}
4. Upload the wp-cache-phase1.php to your web server and try refreshing some cached pages.

The Warning
As you will discover if you read below, I’m not very confident in what I am doing and I’ve stumbled through most of my testing. Implementing this change, while it may fix wp-cache, may create other problems. It may not, though. I really have no idea. Also, I was having problems with a header for Last-Modified - I have no clue whether others are going to see the same issue. My solution may not be a solution at all. All I can say is that in my opinion, it appears to work. At any rate, use this at your own risk!

The Explanation (From a Novice)
I am absolutely new to WordPress, PHP, Apache, etc. I am a Java developer by profession so I can read the code but I suspect many of the steps I took, which are described below, were an absolute waste of time created by my ignorance. My hopes are that an expert may be able to review this and explain better why the problem occurs (so I’ve included all the steps I’ve taken working on this issue). Also, if you are also a novice and are interested in understanding some of what I discuss, it would be best to review the readme.txt included with the wp-cache plug-in.

When I started reading about WP-Cache I immediately started seeing articles (for example, here and here) regarding problems when using GoDaddy. Depressing me even further: most of the responses I found seemed to simply write-off the problem as an unaddressable GoDaddy issue. Honestly, after seeing so many people state so convincingly that any 500 Internal Server Error is GoDaddy’s problem and nothing can be done to fix it, I was inclined to simply believe that there was no hope.

Regardless, I decided to give the plug-in a try hoping that maybe there was some difference between my GoDaddy server and everyone else’s (heh). The install went well and even the first time I loaded a page I could see it appear in my cache. My excitement lasted about 5 seconds: after a refresh I was viewing the dreaded 500 Internal Server Error. I fooled around with some settings on the plug-in itself but it did no good. Things appeared to be broken. Before giving up, I decided to view the source of the 500 Internal Error page, believing there might be some clue there. To my surprise, the entire code of my page was in the source! In other words, I was not seeing the expected 5 lines of source for the 500 error but rather 100+ lines of the page I actually attempted to load. This was exciting to me because now I could add some debug and try to determine where the problem was occuring.

My first thought was that if the page was loading, the first part of (wp-cache-phase1.php) was working and it must be the caching of the page to disk (wp-cache-phase2.php) where the problem existed. I found the line in wp-cache-phase1.php that called phase2 and commented it:
// wp_cache_phase2();
I reloaded my previously cached page but the problem persisted. This was a good thing, though, as I found the code in phase1 more understandable.

At this point, I started commenting out different sections of the phase1 code. I discovered all my problems disappeared when I commented out the foreach loop that creates the headers. I added logging to this section and found that I had two headers:

• Last-Modified: Sat, 08 Sep 2007 13:31:29 GMT

• Content-Type: text/html; charset=”UTF-8″

Then, instead of using the foreach loop, I manually tried each of the headers individually. Testing Content-Type went fine but testing Last-Modified and the 500 errors reappeared. At this point, I created a new php file to test the Last-Modified header (you can view the source here). I named this test.php and loaded it successfully (you can test it yourself if you would like. When I reloaded it, though, the 500 error occurred! At this point, I read a little on the Last-Modified header and decided to disable the cache on my web browser. Now the problem disappearred no matter how often I reloaded…so the problem seems somehow related to when a browser is deciding if it needs to request to redownload files (I’m out of my league at this point).

The Help?
And now, I am at a loss. I can implement wp-cache but only if I explicitly ignore Last-Modified headers. Will this create problems? According to this document, I should always send Last-Modified when able. I restored the old code to view the headers when the page displays properly versus when it does not (500 error) and they are identical:
Date: Sat, 08 Sep 2007 13:59:19 GMT
Server: Apache
Last-Modified: Sat, 08 Sep 2007 13:31:29 GMT
Keep-Alive: timeout=15, max=99
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html; charset=”UTF-8″

200 OK

The fact that the 500 error occurs intermittently (normally every other time) is also very confusing. How is an identical Last-Modified header causing problems half the time? And why does disabling cache on my browser (Firefox) cause the problem to disappear?

If any experts out there want to weigh in on this, I’d love for you to do so. For now, I’m going to continue to use my “fix” by ignoring the Last-Modified when serving cached pages.

AT&T GoPhone Pick Your Plan

In mid 2006 Cingular decided to offer its popular MEdia Net plans on Cingulars PYP GoPhone service. Using PYP requires automatic payment with either a credit/debit card, or ACH from a checking account. If the payment fails, the customer must call and make payment within 4 days, or they lose their “roll-over” minutes.

Since the consolidation of Cingular and AT&T Inc, the company has begun offering prepaid data options on Pay As You Go. Data rates run from $4.99 for 1 MB of data, to 5 MB for $9.99, up to unlimited data usage for $19.99 per month. These so-called Feature Packs, can be added to a user’s account monthly by calling 611. The data plans do not renew automatically.

Some users have noted that since GoPhone can be used with any compatible GSM or UMTS device (unlocked to AT&T), that the unlimited prepaid data can now be used as a data-only option (for use with smartphones and mobile broadband cards). This effectively dramatically lowers the cost of data versus the typical wireless data plan.

AT&T GoPhones

* Any AT&T, Cingular or Unlocked GSM handset supporting the 850 MHz band.

As GoPhone accounts are not authorized to roam on the 1900 MHz T-Mobile GSM network, handsets lacking the 850 MHz band will perform poorly if they get a signal at all. This limitation applies to many tri-band European handsets that only support the 900, 1800 and 1900 MHz GSM bands.

Ordering Problems

ATT Wireless frequently rejects online GoPhone orders stating that the individuals credit history could not be verified, even though it is a prepaid service that does not require a credit history check. This “credit history verification” is thought to help seek out terrorists that use prepaid phones for communication. (citation needed.)

We’ll only display one ad per search query for advertisers sharing the same top-level domain in the display URL. This means that if you’re an affiliate advertiser, your ad may not show for a query because another affiliate or the website that runs the affiliate program also has ads using the same (or a similar) domain in the display URL. Also, your site should not mirror (be similar or nearly identical in appearance to) your parent company’s or another advertiser’s site.

For example, for the domain google.com, we would determine the following URLs and display URLs to be equivalent:

• home.google.com
• www.google.com
• google.com
• www.google.com/home
• www.Google.com

However, we’d determine the following display URLs to be distinct, since each has a different top-level domain:

• www.google.co.uk*
• www.google.fr
• www.google.com
• www.google.edu
  *Domains with a specific extension are considered distinct.

For more information about this change, please review the January 2005 Google AdWords service announcement.

Helpful Definitions:

Display URL

This is the URL displayed on your ad to identify your site to users. This URL displayed is limited to 35 characters; it need not be the same as the URL your ad links to, but it should be an actual URL that is part of your site.

Domain

Website domains are a naming procedure by which web users may identify a particular website address and location (e.g., www.google.com). They are usually made up of two parts: a name and a category. The following are common URL domain categories: .com (commercial), .edu (education), and .gov (government). Domain categories can also be location-specific, for example: .fr (France) , .br (Brazil), or .jp (Japan). In some cases, one category is appended to another category, for example: examplename.co.uk, examplename.com.ph, examplename.org.uk).

What is TTS?

TTS, or Text-To-Speech, is the creation of audible speech from computer readable text. There is more background in the FAQ.

Our research group’s charter is to increase the naturalness of speech synthesis significantly while maintaining good intelligibility. Next-Generation TTS was introduced in 1998 and marked a dramatic leap in naturalness. Now called AT&T Natural Voices™, it is still broadening the range of applications in which TTS can be deployed.

In some cases, such as telephone response, a TTS voice may supply the only feedback a user gets, and the quality of an entire service may be judged by that voice. TTS is closest to the customer’s ear.(R)

> TV Commercial Highlights AT&T Voice Technology

In April 2006 AT&T launched a national television commercial highlighting voice technology, its long development history within AT&T, and its use in current services. The robot hand at the beginning is demonstrating the Voder (”VOice coDER”), shown by Homer Dudley at the 1939 World’s Fair. A human operator used the contols to manually control the sound output.

> Red Planet

Red Planet, the Warner Bros. movie released on 11/09/2000, uses our TTS as the voices of the space ship (female) and the astronauts’ space suits (male). Here’s the press release.

> I Am Sam

This movie, starring Sean Penn and Michelle Pfeiffer, used our “Crystal” as the voice of Pfeiffer’s voice-activated cell phone. Please note that we take no responsiblity for the infuriatingly inaccurate speech recognition in the movie

> Discover Magazine

Discover magazine describes synthesized speech as both a triumph of technology and the fruition of a very old dream. The article follows the evolution of AT&T Natural Voices™, the productized version of our work.

Unfortunately, the article credits us with inventing just about every facet of modern TTS technology. As I understand it, AT&T was asked to verify certain facts but did not get to preview the article prior to publication. (In fact, my mother-in-law read it long before any of us.) We take some comfort knowing that people active in the field are well aware who invented what. And I’m sure our friends and colleagues will refresh our memories from time to time

Let Your Application Speak For Itself!

TTS technology can be useful whenever a computerized application needs to communicate with a customer or user, and so is especially useful in telephone services. Though recorded material still provides the highest quality, recordings are often impractical due to cost or time constraints. Some typical uses for TTS technology are:

* customer support dialog systems, e.g. help desks
* interactive voice response (IVR), e.g. banking, class enrollment
* unified messaging, especially email reading
* screen reader programs for the sight-impaired

In order to protect AT&T and its customers from fraudulent activity, we limit the number of phones and services that may be ordered online by a single individual or entity.

The good: Extremely portable design; excellent keyboard; fingerprint reader; integrated WWAN radio; great performance; incredibly long battery life when configured with high-capacity battery.

The bad: More expensive than comparable models; lacks built-in optical drive; lacks built-in support for ExpressCards.

The bottom line: The first ultraportable to accommodate Intel’s Core Duo processor, the ThinkPad X60s combines blazing performance and incredible battery life with a full feature set and a compact case. We like it.

The latest model in the ThinkPad X series, the ultraportable X60s is almost imperceptibly lighter and thinner than its predecessor, the ThinkPad X41. Though the X60s improves upon the previous generation by adding a few more features, including built-in WWAN connectivity and the latest Intel Core Duo processors, it still lacks the built-in optical drive found in smaller, lighter competitors, such as the Sony VAIO VGN-TX670P and the Fujitsu LifeBook P7120. And yet the ThinkPad X60s is as costly as the Sony and more expensive than the Fujitsu–our loaded test configuration cost $2,299. Still, the ThinkPad’s keyboard is larger than those laptops’, making it the better choice if comfortable typing is more valuable to you than viewing CDs and DVDs. In general, if you can do without a built-in optical drive, we think the ThinkPad X60s delivers a best-in-class balance of comfort, performance, battery life, and portability.

Measuring 10.5 inches wide, 8.3 inches deep, and 0.8 inch thick at the front (1.1 inches thick at the back), the ThinkPad X60s is nearly identical to its predecessor, the ThinkPad X41. The base X60s configuration weighs a spritely 2.7 pounds, though our test unit, which included an extended battery, weighed 3.5 pounds (the extended battery also adds 1 inch of depth and 0.4 inch of thickness at the back). The laptop’s diminutive AC adapter adds 0.7 pound to its total weight. The VAIO VGN-TX670 and the LifeBook P7120 are smaller and lighter and yet manage to incorporate an optical drive, though they also have smaller displays.

The ThinkPad X60s’s 12.1-inch display has a 1,024×768 native resolution that provides just enough screen real estate for basic business tasks and Web surfing; the Fujitsu’s and Sony’s smaller displays have slightly finer resolutions. Though most ultraportables sacrifice key size to fit a smaller case, the X60s’s keys are large and very comfortable for extended typing. Our only complaint is that the right-side Alt and Ctrl keys are a bit narrow–annoying if you’re accustomed to using shortcuts. As with all ThinkPads, the X60s includes a red TrackPoint pointing stick; beneath the keyboard are three mouse buttons (the center acts as a scroll button) and a fingerprint reader for security. Otherwise, you get just volume controls and a long, blue ThinkVantage button that launches system maintenance, connectivity, and other utilities. Tucked into the lid is a nifty light that illuminates the keyboard in dim environments.

Business travelers will find all the ports they need on the ThinkPad X60s: VGA, four-pin FireWire, and three USB 2.0 ports, as well as headphone and microphone jacks. The laptop also includes slots for Type II PC Cards and Secure Digital cards, though ExpressCards require an adapter (not included). Aside from the aforementioned missing optical drive, the ThinkPad X60s’s connections match up well with those of both the VAIO VGN-TX670P and the LifeBook P7120. Our review model included the X6 Ultrabase docking station ($160 if you buy it as an option), which features a DVD/CD-RW drive in addition to a number of other ports and connections.

Like the Sony VAIO VGN-TX670P, the ThinkPad X60s offers the maximum degree of connectivity, with modem, Gigabit Ethernet, 802.11a/b/g Wi-Fi, and an integrated cellular radio (on select models, including our review unit) that connects to Verizon’s EV-DO data network. Though data plans are still expensive and throughput speeds are occasionally slow, this is a great feature for workers who need to stay connected at all costs.

Priced at $2,299, our ThinkPad X60s review unit featured a solid collection of the latest components, including an Intel Core Duo 1.66GHz processor; 512MB of fast 667MHz RAM; a midsize 80GB, 5,400rpm hard drive; and integrated Intel graphics. Based on its performance on CNET Labs’ mobile benchmarks, the ThinkPad X series realizes some significant performance gains with its Intel Core Duo processor. Its MobileMark score was 28 percent higher than the Pentium M-based Fujitsu LifeBook P7120’s and 32 percent higher than the Sony VAIO VGN-TX670P’s; the X60s also bested its predecessor, the 1.5GHz Pentium M-based ThinkPad X41, by 28 percent. Those speed gains are enough to notice with average use and will be particularly useful for multitasking. The X60s’s 8-hour, 16-minute battery life is the longest we’ve ever seen–very impressive, though not quite surprising, given that our review unit’s price included an 8-cell high-capacity battery. The battery costs $143 if you buy it as an option, and we think it’s worth it.

Like other ThinkPads, the X60s is backed by either a one-year or a three-year warranty, depending on the configuration you buy, and reasonably priced upgrades are available. Lenovo’s support Web site includes a handful of troubleshooting topics, as well as the expected driver downloads; the site lacks interactive features such as customer forums or the chance to chat in real time with a technician.
