GETTING THE MESSAGE: I've been harping on the failures of "Rule #1" for some time now, and it seems that the attitude is catching on. Slowly, but at least progress is being made.

IT ISN'T JUST ME: I've recently expounded on the issue of dogmatic teaching in the self defense world, and I'm not alone in my criticism. Check out this post from Roger Phillips over at warriortalk.com, then read the entire discussion. (I've never met Roger, don't know him from Adam, but he makes sense. Can't say that about everyone.)

POCKET COMPANION: no, not a J-frame! From Dustin's Gun Blog I learned of a new iPhone/iPod Touch app called Legal Heat. It's an interactive version of their printed guide to concealed carry and gun laws in all 50 states, written by attorneys and instructors. It' a great idea, and something that's needed. Unfortunately, despite the viability of the concept I cannot in good conscience recommend this particular app.

There is a big issue with Legal Heat's usability. The pages are just images of the book, which means they're pictures and not text. This sounds inconsequential, but it's not. When you bring up the laws on a state, because it's showing the whole page the text is tiny; unreadably small. To read it, you need to magnify the image by pinching. (The usual double-tap doesn't work, because it doesn't work on full-frame images!) Once you magnify the image to read the text, you have to continually scroll back and forth because images don't wrap text. Finally, the app doesn't support screen rotation; it only displays in portrait orientation, which exacerbates the scrolling issue.

Frankly, iPhone users are accustomed to a higher level of application quality than Legal Heat delivers. If they would simply make their pages actual text and enable screen rotation I'd be comfortable recommending it. As it stands, even at $1.99 it's not worth the hassle.

DEAL ALERT: My background in commercial photography has left me more than a little anal retentive with regards to optics, particularly when it comes to binoculars. I'm a fan of porro-prism designs, as they a) have better three-dimensional perspective, b) are brighter, and c) cost less than roof-prism types for any given level of optical quality (resolution/contrast.)

Minox makes some of the best porro-prism binocs. The optical performance is exceptional, and the build quality matches the glass. They make an 8x and a 10x version, and at a street price of roughly $550 they are something of a bargain; you'll need to spend roughly twice as much to get a roof prism of comparable performance, and you still won't get the perspective advantage that the porro-prism design gives you.

Despite their advantages, porro-prism designs are distinctly unfashionable these days and don't sell well regardless of brand. Roof prisms are what people buy, and Minox has bowed to the market: they've discontinued the 10x model. SWFA is closing them out at $299.95, which has to be classed as a screaming good deal. You won't find anything even approaching their optical performance for that kind of money. (Yes, I grabbed a pair - for that price, I wasn't about to pass them up!)

Once upon a time, two geeks met in college. They had some neat ideas about the world of computers, and were anxious to put their ideas into production. They started a little company.

Shortly after they incorporated, they introduced a new computer - one that was more accessible, more flexible, and under the control of a single person. They didn't make many of them, and very few exist today, but with it they changed the face of computing forever.

No, I'm not talking about Jobs & Wozniak. I'm thinking of Ken Olsen and Harlan Anderson, and the company they founded - Digital Equipment Corporation. DEC, as it would come to be known, introduced what was really the earliest commercial incarnation of the personal computer: the PDP-1.



The PDP-1 certainly didn't look like what we've come to expect of the PC. Nevertheless, it started the downsizing of computing power, and introduced a concept critical to the modern PC: user interaction, as opposed to batch data processing. This shift was the necessary step to creating true personal computers, and DEC got there first.

Interactivity opened up huge new vistas for the computer. The PDP-1 has the distinction of initiating things we now take for granted: text editing, music programs, and even computer gaming. (The very first computer video game, 'Spacewar!', was written for the PDP-1. Yes, you have DEC to thank for your Wii.)

DEC only made 50 PDP-1 machines, of which only 3 are known to have survived. All of them are currently in the collection of the Computer History Museum. One is fully operational, and is demonstrated twice a month by running that historic computer game. They've got a terrific website that details the history and restoration of the PDP-1.

Back in '51, the Atomic Energy Research Establishment in Oxfordshire welcomed a new member to their staff: a computer. Today we don't even bat an eyelid when a new PC shows up in the office, but back then computers were a Big Deal. (After all, how many new staff members get their own office - the largest one in the building?)

The Harwell Computer, later to be known as "WITCH" (Wolverhampton Instrument for Teaching Computing from Harwell), now occupies a unique position in computing history. It holds the distinction of being the world's oldest surviving computer with electronically-stored data and programs. All the original parts are present and it is capable, in theory, of being operated.



Though it hasn't been switched on for over 35 years, it is now being restored to operational status at the Museum of Computing at Bletchley Park. They expect the restoration to be completed next summer, at which point the WITCH will be able to claim another title: oldest operational computer, beating out the Ferranti Pegasus whipper-snapper at London's Science Museum.

Well, at 110 baud, it's a slow trip!



This Teletype is identical to the one I used in high school to access a computer timeshare system. Back in the mid-'70s, practical personal computers were still a ways off, and even minicomputers (like the DEC PDP-11) were far too expensive for most high schools to purchase. The affordable way to computer power was to buy a subscription to time on a mainframe computer, and dial in on their telephone lines.

Our school was out in the boonies (no, seriously, we were) and we linked to a computer located in Portland (OR). We used the ASR-33 above to interact with the computer. The dial on the right was used to call one of the access numbers; if it was busy, we tried the next one.

As I recall, we had three numbers on which we had access, and if all three of them were busy (other users of the service), we had to wait until a line was free. For those who have grown up never having used a rotary phone, there was no such thing as speed dial or automatic redial!

We could use the paper tape reader on the left of the machine to feed in a program, or to save a program from the computer's memory. At the blazing speed of 10 characters per second, it took a LONG time to feed in a program - sometimes 30 minutes or more. We had a couple of large filing cabinets full of paper tape rolls, programs that other students had written or ones which the company supplied to us.

The computer output was printed on the typewriter in the center of the console. It used a roll of paper that was about 8" wide, and in our case was a dull yellow color.

Yes, I'm old, but your turn is coming, kids - someday your children will be laughing at the idea of your beloved iPod!

One might think that this era in history is the most well documented that has ever existed. Why, we have photography and sound recording and movies (and their digital equivalents.) Everything, it seems, has been saved for posterity. How much better preserved we are than our forebears!

Yep, you'd think so. And you'd be dead wrong.

There are huge gaps in our archival record, and oddly enough they have to do with the very things that should be most easily chronicled: our technology. Obsolete technology is disappearing, and with it a vital understanding of what we as a species have accomplished in this world. Decorative arts seem to be deemed worthy of perpetuation, no matter their relative importance, while everything else is consigned to the scrap heap.

Take just the computer - there are surprisingly few organizations who have made an effort to preserve this recent technology. With programmable computers being no more than about 60 years old, we should have a very good record of all that has passed in their development. We don't. Old computers are rare, and the earliest (physically largest) machines are virtually all gone. Of those first pioneers we have nothing but a few bad photos and the occasional fragmentary drawing.

That's just the tip of the iceberg. There are many other gaps in our historical records through which technologies, people, organizations, and companies have fallen. There are a few places attempting to preserve bits and pieces of our technological past, and one of them is the Southwest Museum of Engineering, Communications and Computation (SMECC).

SMECC maintains a fascinating site that gives a good feeling for the breadth of their collections. Particularly valuable are the first-person chronicles of the people who actually made the things in the museum's collection.

A warning: their site is perhaps the worst example of Microsoft FrontPage design. It's not nice to look at, not well laid out, and you'll have to poke around to find the gems. It feels like a throwback to the early '90s internet, which I suppose one could argue is appropriate for a museum. (With all that, it's still better than the average MySpace page.)

Any self-respecting geek could easily spend days there. Whether you're into computers, radios, or microscopes, SMECC has something for you.

Heard of the Large Hadron Collider? It's the world's largest particle accelerator, located on the French/Swiss border. A particle accelerator, colloquially termed an 'atom smasher', is a device that uses electric fields to propel electrically-charged particles to high speeds. By colliding particles together - sort of a subatomic head-on crash - we can do all kinds of things. A low-energy accelerator forms the viewable image on a cathode-ray tube (CRT), medium-sized units are used to create isotopes for medical research, and the biggest, highest energy installations help scientists learn about the fundamental structure of the universe.

Long before the LHA was even conceived, the United States boasted the largest particle accelerator: the Bevatron at Lawrence Berkley National Laboratory. Built in the early 1950s, it had a nearly 50-year career before it was finally deemed too expensive to maintain. Mothballed in 1993, the decision was recently made to dismantle the gigantic machine to make room for new research facilities on the crowded campus.

Wired has a great article, with many pictures, on the continuing demolition.

In 1997, NASA launched the Cassini spacecraft to study the planet Saturn. It finally reached the ringed planet in 2004, and started sending back some positively amazing images. The craft continues to work perfectly, and as a result the mission has been extended to 2010.

It may surprise you to learn that the vast majority of transatlantic data traffic - phone calls, email, internet connections - doesn't go through satellites. Instead, most of those bits and bytes goes under the water through long cables stretched between the continents. Sounds awfully low-tech, doesn't it?

When the first undersea cables were laid, traffic was in the form of the telegraph message. Later, as the telephone became prominent, voice channels were added. There were some attempts to use radio to carry communications across the sea, but cables on the seabed were still the way most Americans kept in touch with Europe. It was that way up until the mid-1960s, when the first communications satellites were launched.

The satellite was the darling of data travel, and for a time it looked like underwater cables would be relegated to the back of the communications bus. By the early '80s, over half of all overseas traffic was carried on satellites, with more space-based capacity planned. Then something interesting happened...

In 1988, the first fiber optic cable between North America and Europe went into service. Fiber optics held the promise of bandwidth that was orders of magnitude greater than the copper wires previously laid in the Atlantic, and the new technology didn't disappoint: that first cable itself offered half of the entire bandwidth available on all of the communications satellites. Another cable would exceed the space capability, and that was just a start. Fiber optic cables were cheaper to deploy and had a much longer service life than any satellite, with corresponding reductions in the cost of moving data from one side of the earth to the other.

It didn't take long for the commercial satellite business to experience a serious drop in popularity; today, it's estimated that satellites carry less than a half-percent of all traffic between the U.S. and the rest of the world. Fiber optics were a hit, and it doesn't look like they'll stop being a hit anytime soon.

Thanks to all this fiber optic bandwidth we have the world wide web, which allows us to go back and relive how it all started: with insulated wires dropped off a ship into the middle of the sea. Here is a great site devoted to chronicling that early technology, complete with maps of historic cable routes.

I'm gratified - and somewhat surprised - at the tremendous response to last week's post "Risk assessment, or lack thereof." One of the difficulties I've found with this whole blog adventure is predicting what will resonate with my readers. In some cases I've been deliberatively provocative in order to get people to think outside of their comfort zone, while in others I've tried to deliver solid technical information not readily available in the swamp that is the internet.

On occasion (as with the article under consideration) I worry about whether I'm talking over my audience, that the subject might be a bit too abstract. I'm happy to find that my readers are significantly more discerning than average.

One complaint about the Bianchi SpeedStrips is that they're not available in calibers other than .38/.357. I'm surprised that, until tipped off by a reader, I didn't know about Quick Strips from Tuff Products. They appear to be a clone of the Bianchi product, but are available in a wide range of calibers. Check 'em out.

You may have heard that the U.S. Attorney General called (not surprisingly) for reinstating the infamous Assault Weapons Ban. What was surprising was Speaker of the House Nancy Pelosi's adamant refusal to consider such legislation. Mr. Obama's administration may find their road tougher sledding than they'd originally anticipated. All the better for us!

A while back I wrote about the iPhone/iTouch ballistics application iSnipe. While it worked well, it was pretty basic; as I explained to the author, it needed some features added to enhance utility for the serious long-range shooter.

It didn't take long for competition to appear: Ballistic FTE has everything I ever wanted, and then some. It is superb in every respect; you must see the target recording function! It even has a calculator to help with rangefinding (mil-dot) reticle use. Ballistic FTE is a bargain at $9.99.

Last Monday I told you about NOBal Comp, the online ballistic calculator for the iPhone. I also mentioned that I was waiting for someone to come out with a native iPhone ballistic application.

Well, a couple of days later I got a nice email from Mat Pridham, founder and chief designer at WebDiligence.ca, the company that developed NOBal Comp. He said that they had a native (offline) ballistic calculator for the iPhone in the works that would hit the App Store on Monday (today.)

That was on Thursday. Last night, curiosity got the better of me and I checked the App Store. There it was - iSnipe, the iPhone ballistics calculator!

Of course I bought a copy (am I the first??) and immediately put it to use. Keep in mind this is v1.0, with all the caveats that entails, but it works as expected and the data generated is as accurate as any other ballistics calculator I've used. It lets you save and recall specific load information, which is one of those "must-have" features, and even supports portrait and landscape orientations.

Mat tells me that the next release will have some neat new features. I don't think I'm at liberty to disclose anything, but this is shaping up to be one heck of an application. Serious shooters will find it invaluable.

iSnipe is a very reasonable $4.99 at the App Store.

I've previously mentioned my appreciation for the work that NASA has done over it's 50-year history. NASA grew up right along with me - or me with it - and NASA was always doing the exciting stuff boys of that era were smitten by: Astronauts. Fast planes. Rockets. The Moon.

(It wasn't just spectacle, though; NASA was the catalyst for technological progress that continues to be felt today. A surprising number of the things we now take for granted can be traced directly back to some NASA project.)

We learned about the exploits of the engineers, technicians and astronauts through NASA-supplied pictures in the magazines of the day. My early interest in science was kindled by those pictures, and some of them I still remember.

NASA documented everything, but not all of their photos were of general interest. A large percentage of their images were never seen by the general public because the media was understandably reluctant to publish anything of interest only to nerds. Through the magic of the internet, however, we now have ready access to some of those great pictures.

The agency has launched a new site just for NASA images. You can search or browse and download your selected pictures, drawings, and illustrations - some of them of quite high resolution. You'll find lots of astronomical images, of course, but you'll find all kinds of other things too.

Two of my favorites from the 1969 launch of Apollo 11, taking the first men to the moon:




Saturn V rocket FTW!

If you're a science buff like me, you can spend large amounts of time on their site. I recommend that you not try this a) at work, or b) when your significant other expects you to be paying attention to him/her/the kids/household chores/your dinner guests. You have been warned!

If you're under 40, the name Douglas Engelbart probably means nothing to you. It should, though, because a huge amount of the machine on which you're reading this sprang from his fertile mind.

Engelbart (yet another product of Oregon, having been born in Portland) worked at Stanford Research Institute (SRI) before the dawn of the personal computer revolution. Many of the things we now use without a second thought were developed by him, or made possible by his work: bitmapped screens, the graphical user interface (GUI), hypertext, and networking. The very birth of the internet occurred when his lab at SRI and it's counterpart at UCLA networked their computers to become the first two nodes of ARPANET.

His greatest moment would have to be his "Mother of All Demos" in 1968. In that presentation, he introduced to a stunned world the early working implementations of video conferencing, teleconferencing, interactive text, email and the aforementioned hypertext. It is, perhaps, the single most important event in the history of modern computing.

One of his inventions revealed for the first time at the Demo was a new invention: the computer mouse. It would take over a decade before his now-common pointing device finally reached the market (attached to the ill-fated Xerox 8010 Star Information System), and several years after that before it came to the notice of the general public (as an integral part of the original Macintosh.)



(John C. Dvorak, computer pundit, wrote in 1984 of the new Mac and Engelbart's invention : "The Macintosh uses an experimental pointing device called a 'mouse'. There is no evidence that people want to use these things." Dvorak is not known for his prescience, which surprisingly fails to deter his continued employment.)

YouTube has the entire Demo available.

The Defense Advanced Research Projects Agency (DARPA) recently turned 50. What's DARPA, you ask? Well, it is the agency that invented the network upon which you are reading this missive.

DARPA was founded to do fundamental, high-risk research into science and technology that could be used for military purposes. Today that sounds ominous and vaguely sinister, but in the 1950s it was exciting and patriotic.

One of their projects was called ARPANET (Advanced Research Projects Agency Network), intended as a way for DARPA staffers and researchers to disseminate information and share computing resources. It introduced email, file transfers, and even voice protocols into common use, all made possible through the magic of packet switching - another DARPA innovation. This groundbreaking computer network would, with their guidance, evolve into what we now call the internet.

(Funny, isn't it - the internet upon which you can read anti-military and anti-American rants until your eyes launch themselves from their sockets is the product of an American military project. Euro-weenies will no doubt point out that the World Wide Web was the invention of an Englishman working at a Swiss lab, but his contribution - important as it is - was simply a way of easing access to information on the already vast internet. His work would not even have been necessary had it not been for DARPA.)

The computer network wasn't DARPA's only development, of course - the magnificent Saturn V rocket and the computer mouse both came from the think tanks at the agency. How's that for a wide ranging legacy?

Happy Birthday, DARPA - keep up the good work!

When I was a wee lad, America was at the forefront of space exploration. By the time I was old enough to know what was going on, we'd recovered from the shock of the Soviets beating us into space, and had responded in a big way with Gemini and Apollo programs.

In those days, our grade school classes would literally come to a halt as we gathered around a television set to watch a liftoff or a splashdown. The mighty Saturn V rockets - spewing a fireball that remains unequalled for sheer excitement - would take our astronauts into space for yet another thrilling mission. Landing men on the moon was our crowning achievement, watched by just about everyone in the country.

Space flights were national events on a scale that I haven't seen since - and probably never will again. The SuperBowl and American Idol Finals may draw larger audiences, but in terms of captivating our collective conscious, of instilling pride in our country and what we were capable of doing, they will ever equal the NASA of the mid 20th century.

NASA has put together a little retrospective of their first 50 years, using photos that have rarely been seen publicly. If you are a child of the '50s or '60s, this will bring back stirring memories of what we briefly referred to as Cape Kennedy.

For those that actually remember the dawn of the computer age (my first computer experience was on a time-shared GE 600-series mainframe), looking over old computer advertisements brings a flood of reactions: amusement, embarrassment, and the occasional "I wish I'd bought their stock when it was first offered." (Of course, there is also the "I'm glad I didn't buy any of their stock!")

Take a look at these vintage ads. I particularly like the one explaining what email is - not just for the content, but for the company promoting the concept. (Honeywell, once a player in mainframe computers, is perhaps best known these days for making thermostats - which is what they made before they bought their way into the computer business.)

It's confession time: I'm a geek. A card carrying, spent-all-my-high-school-time-in-the-library, know-how-to-use-a-sliderule geek. I love computers, think physics should be taught in kindergarden, and generally find technology of all kinds (modern to ancient) fascinating.

Seems I'm not the only gun blogger to claim that moniker: the infamous Tam purports to be a geek, too - but is she? Is she really? Oh, yeah, she makes a big deal about her old computers - but did she ever have a DEC PDP-11/70 (running RSTS, no less) in her garage like I once did? I think not!

I, on the other hand, can prove my exalted status beyond a shadow of doubt, as I possess the ultimate geek credential: an amateur radio license. No, not your simple no-code-Tech paper, but a real I-passed-the-Morse-code-test-and-have-HF-privileges-to-show-for-it General class ticket.

That's right - an undersea cable. I'll bet you thought that undersea cables were a thing of the past, right? You probably had it in your mind that satellite technology had rendered the undersea cable a relic of a bygone age, didn't you? As Gomer would say, "surprise, surprise, surprise!"

The vast majority of telephone and internet traffic flows on undersea cables, to this day. Compared to satellites, cables are cheaper and have much greater bandwidth. As a result, there are hundreds of cables in use today, and well over 1,000 cable landing sites (where the cables come ashore) around the world. Here's a good graphic of the undersea cables - and their load - in use today. Wikipedia has a good article on cables, with lots of links to other sites that can tell you everything you ever wanted to know about the subject!

Of course, all those cables sitting on the ocean floor are subject to lots of forces, and sooner or later they break. So, how do you repair a cable that might be thousands of feet deep, well below the ability to use human divers?

So, let's say that you were going to buy me a new cel phone. What do you think I'd want?

How about a Blackberry Pearl? Too "Geek bondage." A Motorola Razr? They are SOOOOOO 2006. Nokia N80? If I wanted a slide-out I'd buy an RV. The Apple iPhone? Tempting, and it would go great with my Macs, but no - there's something even better.

The cel phone I really want is the Portable Rotary Phone from Spark Fun Electronics. Inside this antique is a fully functional cel phone module that utilizes all of the phone's original parts for their intended purposes: the handset, the dial, and even the two-bell ringer!



My Father, who was an inveterate prankster and a telephone company employee, would've loved this thing. It would be just the ticket to out-annoy the clods who use their phones in restaurants, and imagine the looks you'd get in meetings ("sorry, but I have to take this call.")

Perhaps it's normal when one reaches a certain age, but occasionally I have small episodes of nostalgia, and one of the things I miss is the thrill of our space program. Oh, for the days when people would gather around the television (black-and-white, of course) just to watch one of our beautiful Saturn IV rockets blast into space - secure in the belief that with each one we were leaping ahead of our Cold War nemesis. ("Take that, Comrades!")

It was exciting on many levels, and we never missed a liftoff - they were big events. I remember getting up very early one morning to watch Apollo 11 blast off for the moon; heck, we even waited for the splashdowns! (For those of you born after 1980, that's how astronauts landed before the wheeled Shuttle was developed.)

Not surprisingly, I was thrilled when I came across the International Space Artifact Collection at www.hightechscience.org They have artifacts from both the U.S. and Soviet space projects, and have lots of great pictures on their website. Cool stuff!

NASA has made a decision to repair the aging Hubble Space Telescope.

I remember when the Hubble was launched in 1990. Once in orbit, NASA discovered a flaw in the main mirror. It was thought that the flaw would doom the Hubble to uselessness, but in '93 NASA sent a repair crew to restore the telescope to its planned quality. It worked, and the Hubble began to transmit the kind of startling images that everyone had hoped for.

Now the gyroscopes on the telescope have reached the end of their service life, and the only way to replace them is to send another manned mission. The only trouble is that NASA has a much better understanding of just how dangerous those missions are in the wake of the Columbia disaster, and they have been a bit reluctant to risk the lives of a crew - not to mention spending a healthy chunk of their operating budget - on such an expedition.

Last Tuesday, they finally reached a decision to repair the Hubble. This is great news for all science buffs, and serves as a chance for me to post one of the terrific images made by this marvel of American engineering. I give you the Crab Nebula, as only the Hubble Space Telescope can present it!

In the late 1700s, Professor Georg Christoph Lichtenberg noticed some interesting patterns forming on the dusty surface of a charged plate. He showed the unusual works of natural art to his students and peers, and through time they have become known as Lichtenberg Patterns. The same patterns can sometimes be seen on the skin of people who have been struck by lightning.

Formed as the result of high voltage discharges on, or within, insulating materials, Lichtenberg Patterns can today be captured permanently by discharging the output of a linear accelerator into a Lucite block. The resulting three dimensional fern-like patterns are strangely fascinating!

This website shows and explains the process. Very cool!

No more trying to figure out the arcane access numbers - just cuss like a logger (or longshoreman or sailor, as your geographical area dictates) and you might just get to talk to a real person.

The Revolver Liberation Alliance blog isn't just entertaining, it's educational!

Just when I think I've seen it all, someone comes up with yet another unique use for Google Maps.

Go to this site, input a UPS/FedEx tracking number, and iSnoop will generate a Google map showing where the package is, and an RSS feed that sends the up-to-date tracking info to your RSS reader!

What else can be done with Google Maps? Check in next week...

Great idea - turn them into a lamp! From the TechEBlog comes this:



Says the builder: “The pile of CDs that had been massing in my room was growing to epic proportions. So I decided to make myself a CD lamp. The circular base was actually cut using a template on a table saw, then sanded after clamping it in a drill press. The cold cathode lamp is from NewEgg. “

And to think I've been throwing them away all these years...once again, proof that I have no creativity whatsoever!

I make no secret of the fact that I love the Apple Macintosh computer line. I've been using Macs for about 8 years now, and those times when I'm forced to use a Windows PC are excruciatingly painful. I've gotten used to having a computer that "just works" without spending hours reloading operating systems, updating anti-virus software, worrying about spyware, searching for device drivers, and waiting for the machine to reboot after yet another crash.

Whew - sorry for the sales pitch, but I couldn't help myself! Anyway, this isn't about my Macs - it's about the new Apple Store on the ever-chic 5th Avenue in New York:



Get this: it's a glass cube that simply serves as a ground-level entrance to the subterranean store! The cube covers the curved glass staircase (and glass elevator) that leads you downward to the store below:



Very neat. I'd like to have a house built using this concept, but I shudder to think what it would cost...

I like reading the gun discussion forums - lots of, well, interesting stuff turns up - but I've lately become enamored of Michael Bane's Shooting Gallery site.

Based on his TV show (which I can't get because Comcast holds The Outdoor Channel hostage, demanding I pay them even more money than I already am), it has a great mix of articles from Michael and such luminaries as Walt Rauch. Wonderful site, and worth a visit.
