Created a dedicated 'Guides' page. See here » Radified Guides. Been meaning to do that for .. eons. This will allow me to off-load the guides listed here on the home-page, so I can clean it up.

I indented & right-aligned every other link .. to make them easier to read. What do you think? When the links were all lined-up together & left-aligned, they seemed too .. similar.

Eventually I'd like to include a representative graphic for each guide/link. But for now, I just wanted to create a page that contains a repository of the links to all our guides.

On a related note, I've been looking more deeply into MODx, the Content Management System (CMS). They are fixin' to release a new version (complete-rewrite, from the ground up, based on PHP5) .. called » REVOLUTION. (Current version is called » EVOLUTION.)

Drupal would be cool, but it's way too sophisticated for what I need. I don't want/need a PhD in CMS's. Here's a MODx site, for example. (I used to live in Lancaster, PA .. the heart of Amish country. Nice people there.)

I'd like to become intimately familiar with a good CMS .. as another skill to add to my digital toolkit. Only way to do that is » use one daily.

The good people at MODx claim a 'Release Candidate' version of REVOLUTION will be coming » "Winter 2009" (.. which is now). [ Notice how the words 'Summer 2009' have been lined-out. ] UPDATE » They just changed the RC date to "Spring 2010". Hmmm.

The MODx site is running REVOLUTION. I'm in no hurry, tho. Rather make a good decision than a hasty one.

One of the concepts that keeps popping up in my study of Programming languages is » expressiveness. Loosely defined, expressiveness is » the ability to say a lot with a little (my own definition).

Where Programming languages are concerned, expressiveness might be the ability to DO a lot with a little.

Related terms » Meaningful. Concise. Simplicity (as it applies to the elimination of unnecessary complexity). Elegance. Efficiency.

No doubt, you know an 'expressive' person or two. But sheer volume of words does not an expressive person make.

Some people can talk for hours without really saying anything (.. at least not anything meaningful). While others can speak volumes with a simple glance.

In programming, the notion of expressiveness is often touted as a plus, associated with "higher level" languages. I could be wrong, but the idea I get is » the more expressive (a language is) the better. Notice the statement that begins the second paragraph here:

"My contention is that expressive power is the absolutely most important property to focus on right now."

This from a developer with an admitted "unhealthy interest in programming languages," who's currently developing his own. Since the learning process often involves relating new information to things we already know, that's what I've been doing.

As chance would have it, I was watching Hamlet last night (the Kenneth Branagh version). Didn't take long to realize much of what was being said wasn't getting thru. ( "Say what?" )

So I enabled English subtitles and started vigorously working the pause button .. in order to read & digest the Elizabethan chatter. Much better.

Saying Much with Little

Note how the phrase » 'To be or not to be' is exceedingly simple. Yet it carries much meaning beneath the surface (.. especially that 'not-to-be' part).

The ability to "say much with few words" is a primary reason cited when discussing Shakespeare's literary prowess. In other words, it's not just what he says, but the way in which he says it .. that makes his writing so .. descriptive, enchanting.

I'm reluctant to republish the content of others (as so many sites already do), but .. I found it interesting & noteworthy that » Microsoft has acknowledged Linux as a threat .. especially since I spent so many hours in Linux these past few weeks (learning the Unix shell)

Copy-n-paste snippet (minor Rad-editing for brevity):

"Microsoft acknowledges Linux as the first viable competitor to its Windows client business, due to the use of Linux on netbooks, which are rising in prominence as an alternative to full-sized notebooks.

Microsoft cited Red Hat and Canonical -- the latter of which maintains the Ubuntu Linux distribution -- as competitors to its client business, which includes the desktop version of its Windows OS." </snippet>

Notice how the article said » DESKTOP, and not server. Linux has long been a dominant force in the server market (.. if not the dominant force).

It's difficult to describe why Linux is so cool .. why using it feels so fresh & clean. But I think it has something to do with the good intentions .. that come from thousands of talented programmers donating their time & expertise .. to bring you (for free) an operating system they obviously believe in.

I might be imagining it, but I think you can actually feel these good intentions (while using Linux). Can you feel the difference (in intentions) between someone who genuinely loves you, and someone who is paid to love you?

Moreover, I feel our economy has a lot to do with the Linux threat to the Microsoft desktop. No matter how compelling the product, basic economics suggest it's hard to compete with free. (Which Windows is not.) And in these troubled economic times, free means more than it used to.

Today is the 40th anniversary of the first manned lunar landing (1969) .. a historic event for techies .. cuz it was techies who put us there. And techies used » calculus to put a man on the moon (some 240,000 miles away).

At the heart of calculus lies the notion of » limits (a concept I'm quite familiar with, unfortunately).

Calculus was invented to solve (among other things) the problem associated with finding the instantaneous rate-of-change .. as visualized by the slope of a line tangential to any given point on a curve (of a graph).

To calculate a slope, you might recall (dust off them algebraic brain cells) we pick two representative points, find their difference and divide the » "rise by the run" .. the change-in-Y / change-in-X (.. commonly referred to as "delta-Y over delta-X").

As the change in the X coordinates (recall from basic Algebra) gets smaller and smaller, we get closer and closer to determining the slope (rate-of-change) at a particular point.

The problem however .. is that a point has no size, so the "change" or 'difference' (in the X coordinates) becomes zero. And dividing anything by zero is a major mathematical no-no. (Defined as "undefined" .. a mathematical black hole that will crash your computer.)

See t=13:00 here, and especiaaly t=13:30.

Limits

The concept of » limits was introduced to address this problem. Imagine standing in your living room, and walking half the distance to the furthest wall. Then walk half the distance again. And again & again.

Each time, you keep getting closer & closer. But .. you'll never actually reach the wall (cuz you keep going only half the distance). A hundred years from now, you'll be very, very close (to the wall), but still not quite there.

Getting closer & closer to the wall is analogous to decreasing the size of the difference between the two X coordinates along a curve plotted on a standard graph (which contains an X & Y axis). But the limit (drum-roll, please .. here it comes) is » the wall! .. even tho, in reality, you never actually get there.

That's why the notion of a limit represents a mathemetical "concept" (not reality). If you think about it, you can't really have an instantaneous rate-of-change (.. cuz nothing can change in an instant, cuz an instant contains no time). And the word 'rate' implies "per-unit-something." That 'something can be (and often is) » time.

That's also why the result is called/termed a 'derivative' .. cuz you can't get there with conventional mathematical manipulations. It's kinda like what that old farmer told me down South when I asked for directions » "Son, you can't get there from here." =)

I know a guy who used to make serious bank. He always seemed to have a wad of broccoli handy. So it surprised me to learn he's now living in a ditch.

"Where ya been?" I asked, running into him recently. (Hadn't heard from him in months.)

"I moved," he said. "Where to?" I inquired.

"I'm living in one of the most exclusive neighborhoods in San Clemente," he boasted. "Presidential Heights. Not far from where Nixon used to live."

[ I used to live in San Clemente myself, just off Buena Vista, a stone's throw from the beach there, and walking distance to the pier. So I'm familiar with the area. ]

After sharing how his global Internet-based business has been taking a beating, and how he began having trouble making rent, he described how he threw everything into storage (for $55/month) and moved to a "secluded ravine" he'd discovered while surfing nearby.

"I arrive shortly after sunset," he explained regarding his new routine, "and park about a hundred yards away. To discourage hikers, I've moved some brush across the path. I have a sweet little spot, complete with Thermarest pad & sleeping bag. I fall asleep to the sound of the ocean every night."

While showing me a video of his "new home" (recorded on his cell phone), he continued, "A blue jay wakes me every morning. I feed him peanuts."

After an early morning aerobics class (where he showers afterward), he heads off to the library where he begins his work. But while he was in the restroom last week, some kids stole the memory from his laptop.

Been learning the UNIX Shell, which uses a command-line interface (from a terminal) .. something I've wanted to do ever since we upgraded to the Virtual Private Server last year. (Linux is a variant of UNIX.)

Even basic knowledge of (how to use) the Linux command line makes life administering a VPS much easier.

The Shell is simply a program that allows users (like me) to interact with the operating system (sometimes termed the 'kernel'). It can be conceived of as a 'layer' sitting between you and the operating system .. hence the term » shell.

Several shells exist, but nearly all Linux distributions come with » bash (Bourne Again Shell) .. cuz it's free, powerful and easy to use.

On my laptop I have installed a copy of Ubuntu Linux that I use to learn the shell (practice). Before jumping into learning the Shell, I figured this was a good time to upgrade my 'installation' of Ubuntu .. to the latest release (» v9.04, 'Jaunty Jackalope').

So I downloaded » this virtual machine (1.1 gig, using uTorrent). Had trouble getting it connected to the Internet, but that was due to my own inexperience with VMware, and not due to any short-comings of Ubuntu.

Anyway, I am really digging learning the Shell, cuz it's something I can use right away. For example, yesterday I upgraded the blogging software we use here at Radified (Movable Type) to the latest version (» 4.26). Something that used to take hours to accomplish was done in minutes .. (using a series of Shell commands). Beautiful.

It occurred to me again today, while composing a short thank-you note, that Texans donate more to the Rad cause (this site) than all other states combined.

Never been ever to figure out this statistical curio, seeing I live in California.

I've lived in many states over the years .. including Connecticut (where I grew up), Florida, (where I attended both bootcamp & the Navy's Nuclear Power school), Maine (shipyard at Bath Iron Works), Hawaii (the first state away from home to feel like home), Idaho (gorgeous .. in the summer), Washington, Pennsylvania & Illinois, and vacationed in many others, but Texas isn't one of them ..

.. tho I do recall being enchanted with the sense of expanse there as I drove thru the panhandle on I-40 (on my way to California). There was something compelling about the landscape .. readily apparent soon as we crossed the border. Vast & open. Felt like I could see for a hundred miles. Couldn't stop looking, as if it were beckoning.

So maybe Texans are simply the most generous?

Anyway, thanks to all you Texans for your continued generosity over the years .. especially during these difficult economic times, when so many are struggling financially. I'm sincerely grateful.

Frontline is airing a special tomorrow (9PM, May 12th) titled » The Madoff Affair. Should be an eye-opener.

A statement Madoff made in court following his arrest caught my attention cuz it reflected my impressions of the Wall Street culture .. (after I watched » Inside the Meltdown) .. that it seems like everything on Wall Street is about turning a profit .. at any cost .. regardless of the suffering & misery their actions might bring to countless Americans. And that enough is never enough.

How can $50 billion not be enough? That's billion with a 'B' .. as in » $50,000,000,000.00 .. enough to turn 50,000 paupers into millionaires .. 25,000 hobos into multi-millionaires. Feed the hungry (steak & lobster for a lifetime).

Madoff's comments confirmed my impressions .. (nearly word-for-word) .. tho this mindset is difficult to understand, cuz life is short and (very obviously) no one gets out of here alive.

And I dare say he's not the only one. Madoff is merely the poster boy for Wall Street greed.

What kind of dysfunction drives such a culture? Hard to believe that greed alone is responsible .. and there are not more serious psychological defects at play.

With world-economies teetering somewhere between a nasty recession and full-on depression, more folks are turning to open source (free) software to meet their home computing needs.

If you've been Radified any length of time, you know that cloning programs are our specialty, especially when used as a tool to backup your system partition (where Windows resides) by creating an image file.

So the question naturally becomes » What's the best free cloning program?

I've tried many options, such as Macrium and O&O DiskImage Express, but never quite found what I was looking for .. until today, that is.

Perhaps I should interject by saying that, regarding the NOT-free solutions, I've found that Ghost, along with Image-for-Windows to be the best for-co$t disk-cloning tools. (By 'best' I mean » most reliable.) Ghost is also way faster than any other cloning product I've demo'ed .. if speed is important to you.

Lots of people also like True Image, but I had problems with it. (Errors I couldn't resolve.)

But what if you can't afford those apps? Then what? We still need an industrial-strength (nuclear-grade) backup tool. Enter Clonezilla. (Standing ovation.)

First, I'm not crazy about the name .. nor the website's design, especially the tiny menu on the left-side that I can barely read. (Update - looks like they fixed the tiny-menu problem after I posted this.)

Heck, I don't even like their logo (white Linux penguin inside orange penguin). But I *am* impressed with the tool itself .. now that I've had a chance to try it.

Yes, it's significantly more complicated to use than either Ghost or Image-for-Windows, but I don't feel this complexity is a barrier to those with a moderate degree of computer sophistication. (Such as the folks who frequent Radified.)

Note that .. a cloning program can (if used inadvertantly) trash your entire system and wipe out every every file on your hard drive .. with a single click. So you can't experiment like you can with other programs (.. such Photoshop Elements or Sound Forge, for example). In other words, you need to know wtf you're doing.

Perhaps I should begin by defining some terms.

Been researching MODx, a Content Management System (CMS) .. similar to Drupal and Joomla .. tho considerably more 'flexible.'

Being a publisher-of-content myself means I'm always on-the-lookout for cool, new publishing tools. Movable Type has been my tool-of-choice since 2003, but I'm always open to trying new things.

The thing I don't like about Movable Type is that it's difficult to customize. You're limited to one of their pre-designed templates. Even minor tweaking is a nightmare. And it suks when your site looks like so many others.

Before we discuss CMS'es, you should know that Drupal won the Packt Publishing award for best Open Source CMS two years running (both 2007 & 2008). These awards were chosen by guys who know their CMS'es. Tho the judges admit:

There isn't necessarily one CMS that is "the best," but rather the best is the one that best fits a user's needs.

It's unlikely the judges actually used all the CMS'es themselves, since there are so many. Joomla came in second. It's probably the single most popular CMS out there.

As promised, here's some photos from my South Afrikaan friend (who lives in Johannesburg). He works in the Film industry down there and loves cool technology.

Seems like he's always traveling to one exotic place or another .. places with exotic names .. like Drakensberg (Afrikaan: Devil's Mountain) and Patagonia. (Yes, I'm jealous.)

Today's photos come from » Moçambique. (I actually had to look on a map to see where that is .. as is the case with most of the photos he sends.)

Moçambique sits on the east coast of Afrika, just above South Africa. It also shares borders with Zimbabwe, Zambia, Malawi and Tanzania. Off its coast sits the island of Madagascar.

Steve sent 5 pics, with the following note:

Just returned from a weekend escape across the border to Moçambique. Here's some pics from the capital city, Maputo, and surrounding areas.

Jo'burg sits on a high-altitude grassy plain. In comparison to most of Africa, its climate is rather harsh and frigid. Maputo, on the other hand, is further north. It sits right on the coast, and as a result is hot, humid & verdant.

Regulars might recall when I installed a copy of Ubuntu Linux last summer .. an operation I prepared for by creating a separate 20-gig partition (on my new hard drive), which I formatted as EXT3.

Somebody in the forums (Nigel, I think) suggested using VMware (.. either the freebie 'Player' or full-boat 'Workstation' ..) to run a 'virtualized' installation.

I initially balked at the idea .. cuz I didn't grok how virtualization works. But you don't need to understand how an automobile works in order to benefit from driving one. Same goes for virtualization. And the benefits are substantial.

The coolest thing about 'virtualizing' a Linux installation .. is that you can run it from (within) Windows .. just like you can run Photoshop (from Windows) .. or any other Windows-program for that matter .. multitasking all of them at the same time.

I found that .. if you can only use/access Linux by booting into it (and thus leaving Windows behind), you're less likely to use it (.. or so it has been my experience).

So last week I deleted my EXT3 partition, and reformatted it as NTFS .. where I installed a virtual machine containing Ubuntu 8.10 'Intrepid Ibex'.

Intrepid even found my wireless adapter upon initial boot-up. (Woo-hoo!) No more having to troubleshoot wireless connections and installing proprietary drivers just to get internet access.

The only drawback I've found is that you can't copy-n-paste info/text (such as passwords, etc.) between programs running in Windows and those running in (virtualized) Linux. (Tho I wonder if this might help.)
