I Love My Kindle!

I finally broke down and got a Kindle -- Amazon.com's wireless electronic book reader. I'd been meaning to for some time, but the choices and prices were a bit daunting so it was easy to procrastinate.

I had been agonizing over the choice between the 9.7" Kindle DX display and the 6" display on the standard device. After poring over dozens of reviews (at least!) I realized that the smaller size was not only handier, but also considerably cheaper and had much longer battery life. (Of course, the DX may be upgraded soon, being one generation older than its smaller counterpart.)

Having settled on the standard Kindle, one issue remained: Wi-Fi or 3G? Wi-Fi is basically a marketing name for the IEEE 802.11 standard -- a short range radio frequency protocol similar to that used in cordless telephones. The Wi-Fi Kindles require you to be within range of a Wireless Access Point or "hot spot" to download new books. Books already stored on your Kindle (up to 3500) can be read anywhere, any time.

3G refers to third generation mobile telecommunications standards -- known as cell phone technology in the United States. Kindles equipped with this feature will automatically download fresh content such as magazine and newspaper subscriptions anywhere there is an adequate cell phone signal. Although the initial cost of the 3G Kindles is higher, there are no monthly fees. Amazon picks up the tab for the cellular communications, or embeds it it the price of the subscription, whichever way you want to look at it. If you are lost without your smart phone, this may be the right option for you.

I buy a fair number of books if they aren't available at the library, but I rarely feel the need to have them instantly, so I opted for the Wi-Fi Kindle. When Amazon sweetened the deal by taking $25 off the regular price for a model with a software patch that includes some inobtrusive ads, they had me. The Wi-Fi Kindle with Special Offers cost me just over $100. Not bad, considering that there are thousands of public domain books available for free -- so many you have force yourself to be selective!

There's just one "accessory" for the Kindle that you really ought to have: a wireless router. You can get one that will be adequate for downloading books for under $20, although it would probably be wise to spend a little more. I was able to borrow one from a friend who had recently upgraded his, so I was spared the necessity of choosing one right now. I'll be blogging about that selection very soon.

SuperSpeed USB3 500Gb External Drive - Reliable Network Attached Storage Cheap

One reason (or excuse) for my failure to embrace digital photography, is that one never seems to have enough storage capacity for the myriad snapshots that one can accumulate when one doesn't have to buy film. Of course, you can always trot down to the local electronics store and buy an external harddrive, but these tend to be "black boxes" that are short on technical specifications and not particularly cheap.

Furthermore, people seem to have a lot of trouble with these. It's as if harddrive manufacturers stuff the drives that aren't selling into chintzy boxes and put them on the shelves as bait for the unwary. Either that, or people expect too much from these "portable" units. I decided to take another approach and scratch-build a half-terabyte of dependable network attached storage.

My first stop was Tom's Hardware Page. Always a source of reliable third-party reviews, its the starting point for a lot of my computer projects. I was immediately drawn to the Seagate Momentus XT Review. I should have actually read the article, because the drive in question received the rare Best of Tom's award for excellent performance because of it's "Adaptive Memory Technology," which moves frequently-accessed files to non-volatile RAM, increasing Windows boot speeds by 300% or more - not for the prowess of the drive's inherent geometry and mechanics. Seagate's choice of the 500 Gigabyte Momentus drive for the XT modification was instructive, but not conclusive.

Eventually, I found my way to Perfect Notebook Storage: Seven 2.5” 500 GB Drives, which was what I was looking for. It turns out that 500 Gb is the practical limit for current platter recording technologies and common form-factors, so it is a very reasonable size for an economical design. There are also a lot of tried and true 500Gb SATA drives, which Tom's concludes are nearly identical from a performance point of view. Any of these would be a good choice, depending on your specific requirements:


I've linked to the specific drives mentioned in the article cited, but there are other variations. For instance, Seagate drives with "G-Force" anti-shock technology have a "G" appended to their model designation. I settled on the Hitachi Travelstar, primarily because low power consumption and heat seemed far more important to me in this application than other factors, such as drive latency, for example. Your mileage may vary.

I began my search for a suitable enclosure by simply looking for the cheapest available - a box is a box, right? I soon discovered that the $6 plastic numbers were no bargain. In fact, if you're upgrading a laptop (possibly with a Momentus XT) and you just want to clone your operating system and data to a new haddrive, a USB-To-SATA cable might be a better choice. After rejecting the bargain basement cases, the the feature-creep went on and on. Better heat-transfer. Sturdier mounting of the USB-to-SATA electronics. Superior bus power characteristics. Finally, it became clear that the new USB 3.0 specification (SuperSpeed USB in marketing jargon) was what would be required.

Since SuperSpeed USB products only began to appear in Jan. 2010, there is still an early-adopter penalty to be paid with these devices. Although you may currently support only USB 2.0, the ten-fold increase in the data transfer rate of SuperSpeed USB 3.0 nicely matches SATA 2.0 throughput, and its backward compatibility makes it the natural choice for this application.

Returning to Tom's, I found that four USB 3.0 drive enclosures featured in Portable Performance: Four USB 3.0 Enclosures For Your 2.5” Drive were essentially equal, but I opted for the ruggedized Acomdata Samurai, which was not included.

Once you've selected your components, assembly of the unit is easy, even for the severely tech-challenged. (For the truly hopeless, there is the Iomega eGo.) Simply install the drive following the instructions supplied with the enclosure. If you don't have a USB 3.0 connector on your system / network you can add a SuperSpeed USB card to an available PCI express slot for maximum performance. As with the enclosures, the limited number of supporting chipsets for this technology currently make these cards essentially identical. I went with the MSI card.

Halloween : Costumes, Candy , Party Supplies and More

Amazon.com > Clothing > Specialty Apparel > Costumes and Accessories

It's Halloween! Time to haul out the yard displays, crank up the Nox Arcana, don your scariest mask, put the cobwebs and spiders around the door, and prepare to give the costumed children in the neighborhood a little show with their buckets of candy, and their safety glowsticks! HA ha ha aha!

Seriously, Amazon has everything you'd want for Halloween from mild to wild. Fog machines, zombies, sound effects, vampire gear -- you name it, Amazon probably has it. It's time to find all those Elvira DVDs you need. There's so much, in fact I'm planning another Halloween post soon.

Halloween Books


You can find books on just about any subject, which makes them a wonderful tie-in for a mixed department page like this one. While there used to be a specific "Nonfiction Halloween" category, I see than Amazon has just one Holiday Nonfiction category, apparently allowing seasonal sales to bring the appropriate books to the top. It might work.

The Whole Ed MySpace Blog

Following on my Social Media Bible post, I started my own MySpace Page, where I immediately got hooked on a MMPORG called Vampires. If you have 22 or 23 hours a day when you're not doing anything, I highly recommend it.

I started to write this little HTML introduction for that blog largely to explore the ins and outs of their online HTML editor. Eventually I gave up and decided to publish it here:


Before I go on to the substance of what I've learned about the Vampires app so far, I want to digress into just a little bit of HTML. The good stuff will be coming in another post, probably tomorrow. Then you'll see why I'm doing this. If HTML editors like the "compose mode" of this blog are any indication, a lot of people are afraid of HTML. They probably feel that they are applications users, not programmers, and that learning HTML would be a big leap.

Relax! First, Hypertext Markup Language (HTML) isn't even a "real" language -- it's a "markup language." Think of it as a form of punctuation. Second, you don't have to learn the whole language to do useful things with it. Probably 90% or so of what I use it for is covered right here.

First, HTML files are ordinary text files that contain certain elements in a certain way. You can create them with any editor that produces plain unadorned ASCII text. Notepad is perfect for Windows users. Second, you need to tell your operating system that the file should be treated as HTML -- i.e. that it should be opened using a web browser. You do this by giving the file the extension ".html" when you save it -- or ".htm" if you're actually using Windows Millennium or earlier.

Since a big part of what people use computers for these days is Internet access, being able to open files in the web browser and then have them do something is very useful. What I'm going to show you here is how to create a list of links. Instead of adding everything to your favorites, and dealing with all that you just make a list and click on the link you want. That may sound like a lot of trouble to go to, but believe me it's a real time-saver.

The first thing you'll notice about HTML files is that they're full of "tags". Browsers interpret the "less than" sign (<) and the "greater than" sign (>) as angle brackets, enclosing an HTML element, or "tag". These tags come in pairs -- an opening tag consisting of an HTML keyword enclosed in angle brackets, and a closing tag consisting of the slash character (/) followed by the HTML keyword enclosed in angle brackets.

This will become clearer by looking at this pair of tags: <HTML>...</HTML> The dots indicate something was left out that would go there -- in this case your page, because every HTML page begins and ends with this pair. Within every HTML file there are two more pairs, the <HEAD>...</HEAD> section which contains information which is not displayed, and the <BODY>...</BODY> section which is what shows up in th browser window.

We're now ready to create a list of links. We'll make it an ordered list (OL) because it might be useful to have the list items numbered. If you prefer bullet points, that would be an unordered list (UL). Each new item is a list element (LI) and since it is a link it uses the anchor (A) element. The anchor element is somewhat oddly named, until you realize that it is just a hook where you can hang things. The things you hang there are called attributes.

We're only going to cover one attribute -- the Hypertext Reference attribute (href). Hypertext is a quaint old term for text with links in it, and links are the bulk of what makes the Internet so useful. Attributes take arguments -- in the case of the href attribute, the argument is a URL (also known as a webpage address, although that isn't the "real" name.) Most browsers aren't too picky about puctuation, but the "correct" form is:
<A href="(protocol)://some.url.here">Text you want to click on</A>

Putting this all together gives us something like what follows. Highlight everything from <HTML> through </HTML> - paste that into your editor and save it as template.txt or whatever you like. Tomorrow I'll show you something really interesting you can do with this.

<HTML>
<HEAD>
<TITLE>Titles Are Cool</TITLE>
</HEAD>
<BODY>
<OL>
<LI><A href="some.url.here">First List Item</A></LI>
