Typealyzer

Monday, December 1st, 2008

Via Ayende, here's a cool text analysis site: Typealyzer. They should really work on their spelling and syntax though (I made corrections). Here are the results for this site:

INTJ - The Scientists

INTJ

The long-range thinking and individualistic type. They are especially good at looking at almost anything and figuring out a way of improving it - often with a highly creative and imaginative touch. They are intellectually curious and daring, but might be physically hesitant to try new things.

The Scientists enjoy theoretical work that allows them to use their strong minds and bold creativity. Since they tend to be so abstract and theoretical in their communication they often have a problem communicating their visions to other people and need to learn patience and use concrete examples. Since they are extremely good at concentrating they often have no trouble working alone.

The second part of the analysis is this:

This shows what parts of the brain that were dominant during writing.

Who would have guessed? And no gelled electrodes, magnetic fields, or X-rays were involved! 🙂

Upgrade to WordPress 2.6

Saturday, July 26th, 2008

It's been over a year since my original WordPress installation.  I started with 2.4, and ignored the 2.5 release.  Since 2.6 was recently released I thought it was time to take the leap.

I followed the upgrade instructions closely. Here's a summary of the experience:

  1. The backup and upgrade process was straight forward. The instructions on which files to delete and not delete could have been clearer.
  2. Huge gotcha: Lost category and link descriptions. The process for restoring these (WordPress 2.6 Upgrade - Fix Missing Categories) was awful, but at least it worked. If I had known about this before hand I would have waited to do the upgrade until this problem was fixed.
  3. All of the plugins I use were upgraded and re-installed without a problem. I like the new integrated upgrade capability.
  4. I don't use a custom theme so I did not have to deal with any display issues. The new wp-syntax plugin improved code formatting looks great.
  5. The only customization I had to do was add my LinkedIn link to SideBar.php and the Goggle Analytics script to Footer.php.
  6. For some reason the sub-domain link to the blog (http://blog.bobonmedicaldevicesoftware.com) goes directly to the main domain http://bobonmedicaldevicesoftware.com.  I'm sure that my root .htaccess file didn't change so I don't understand why this is now happening. I haven't been able to find a solution yet, so in the mean time I've just re-directed the main page back to the blog.

That's it. Hopefully the new 2.6 features will be worth the effort.

UPDATE (8/15/08):

Upgraded to WP 2.6.1 using WordPress Automatic Upgrade 1.2.1.   WPAU automates WP and database backup, puts the site into maintenance mode, disables all plugins, does the WP new version upload and unpacking, database upgrade, and re-enables plugins.  This update wasn't really necessary for me, but I wanted to walk through the automatic upgrade process just to see how it went.  Everything worked fine, which was expected for a minor release.

I don't know if problem #2 was resolved for 2.6.1 upgrades from older WP versions.  I did a quick read-through of the fixed bugs, but that one didn't jump out at me.

UPDATE (12/13/08):

Upgraded from WordPress 2.6.5 to 2.7 with WPAU. Worked great. The new 2.7 admin interface is nice and the built-in updates will hopefully work as well as WPAU.

I also just noticed that my problem #6 -- sub-domain link to the blog -- has been fixed in WordPress 2.7. WooHoo!

The Joy of Short-term Memory

Sunday, April 13th, 2008

The New York Times had a couple of articles over the last few days that deal with short-term memory loss.

Le sommeil, Salvador Dali (1937)

David Brooks' 11-Apr-08 commentary called The Great Forgetting summarizes the Bad Memory Century best with:

In the era of an aging population, memory is the new sex.

In addition to taxes and death, aging is something that none of us can avoid. I was born in the later part of the baby boom, so over the last few years I have become acutely aware of these short-term memory challenges. Remembering to write down thoughts and lists has become essential. And I'm still young, relatively speaking anyway. Like the other inevitables, you never think it's going to happen to you. But it does!

The 13-Apr-08 Sunday Magazine's Idea Lab Total Recall speculates about embedding a computer chip in the brain in order to improve short-term memory. I know that short-term memory loss is a problem, but who would have guessed that "sky divers have been known to forget to pull their ripcords — accounting, by one estimate, for approximately 6 percent of sky-diving fatalities." !!

Interestingly, the brain is a particularly effective associative memory system:

..., studies suggest that if you learn a word while you happen to be slouching, you’ll be better able to remember that word at a later time if you are slouching than if you happen to be standing upright.

Neural prosthetics are a long way off (see here), but the concept of embedding a Google search engine in your brain is certainly intriguing -- and scary to most.

In the mean time, you can follow the suggestions in How to Cope With Short Term Memory Problems.

Randall Munroe at Google

Thursday, December 20th, 2007

Randall Munroe is the creator of xkcd, a webcomic of romance, sarcasm, math, and language. Munroe on Munroe: "I'm just this guy, you know? I'm a CNU graduate with a degree in physics. Before starting xkcd, I worked on robots at NASA's Langley Research Center in Virginia. As of June 2007 I live in Massachusetts. In my spare time I climb things, open strange doors, and go to goth clubs dressed as a frat guy so I can stand around and look terribly uncomfortable. At frat parties I do the same thing, but the other way around."

This Authors@Google event took place December 7, 2007 at Google Headquarters in Mountain View, CA.

Nerds and managing them

Thursday, December 13th, 2007

If you consider yourself a nerd (or even if you're not sure) then you and your significant other will want to study this:

The Nerd Handbook

Funny stuff because it hits so close to home. It's a great read for both of you.

In addition to a lot of other interesting and humorous content on his site Michael Lopp (Rands) also wrote a book. The introductory web site Managing Humans is very clever.

CA Wildfires: Over but not forgotten.

Thursday, November 1st, 2007

Things are getting back to normal here in San Diego -- except if you were one of the those that lived or worked in the over 1500 lost homes or businesses. 🙁

It's amazing that it's only been a week and the wildfires are already old news . Nevertheless, the NASA satellite images are remarkable:

Southern California Wildfiles: Oct 23, 2007

These latest images, captured by NASA satellites on the afternoon of October 22, show the thick, billowing smoke coming off the numerous large fires and spreading over the Pacific Ocean. Fire activity is outlined in red.

The small white circle is the approximate location of our office. Downtown SD is on the bay just to the southwest. As you can see, the fires to the north and south didn't have much affect on us (and downtown) because the Santa Ana winds were blowing so strong directly from east to west.

The large fire area to the north (which started in Witch Creek) is heavily populated and is where most of the property loss occurred. That fire ended up getting to within several miles of the ocean. It's still hard to believe that over 500,000 people were evacuated from their homes.

I'm originally from the Midwest and thought tornadoes were bad -- hunkered down in the basement with the wind and rain battering the house and sirens blaring in the distance. Even if there were basements in CA I don't think they would help a whole lot in one of these fires. Your only option is to get out.

Here's another NASA image from about the same time (from here):

Wow!

Blogging is hard.

Friday, October 26th, 2007

When I started this blog I told myself that I was going stay on topic. I've strayed a couple of times but blogging about blogging was always very high on the off-topic list.

Then I read How To Achieve Ultimate Blog Success In One Easy Step by Jeff Atwood. He really hits the nail on the head about the motivation and benefits of blogging. So now I'm forced to break my own rules again. [That's actually one of the nice things about having your own blog, you get to make up your own rules -- or break them -- anytime you want.] If you have an interest in starting a blog, read his post and the many links.

From his Fear of Writing post:

It's like exercise. No matter how out of shape you are, if you exercise a few times a week, you'll inevitably get fitter. And if you write a small blog entry a few times every week, you're bound to become a better writer.

One of the reasons I started blogging was because I've always wanted to be a better writer. Whenever I read a great article or book I'm always envious of the writer's talent. It's like watching an athlete: you know how great they are by how easy they make extraordinary feats look. I will never be a superstar (like Coding Horror), but I have so much room for improvement it's a good bet that I'll get better.

Writing is hard. At least it is for me. You might think that you could use some of your programming techniques and skills to facilitate writing. I haven't found that to be the case at all. The whole flow of writing is completely different than programming. When you develop code you're typically implementing multiple trains of interconnected logic in parallel. In order to do this you're jumping back and forth between those pieces of logic.

When you blog, the topic you're discussing may have distinct points or categories, but writing about it requires a single stream of coherent thought. Not only that, you have to be able to write understandable English sentences. All of this is no easy task for an Engineer. Thank goodness for spell-checkers anyway.

Besides the writing part, technology blogging is also a challenge. For some, just finding unique topics can be difficult. This seems to be especially true for programming blogs, mostly because there are so many of them. Fortunately, within my areas of interest I have many topics to discuss that aren't already being covered by hundreds of others.

Actually, it would be nice to have some more company, so I'll ask the same question as Jeff:

So when was the last time you wrote a blog post?

Off Topic: Pandora Radio

Thursday, October 18th, 2007

One of the main reasons I don't listen to a lot of music is that I tend to get stuck in a rut. I'll listen to the same thing over and over again until I'm sick of it. Then I'll just stop all together. I don't own a music player, but I do have headphones on my office computer. I've tried Internet radio stations, but just like regular radio, I end up in switching-channels mode. Then I'll just stop all together.

If you're a music connoisseur you probably already know about Pandora Radio. The whole concept of creating stations based on your selection of an artist or song seems strange at first. Once you understand how the station music is selected, it makes a lot of sense. This is especially true when the resulting play-list matches the attributes of the original so well. As you rate the tracks (thumbs up, thumbs down) the selections get even better. It's pretty amazing actually.

Pandora is a great way to discover new artists that match your tastes. Give it a try.

Coffee: The New Health Food?

Tuesday, September 4th, 2007

I get a lot of grief about my coffee drinking habits. Apparently, it is quite noticeable that I consume large quantities of coffee. People inevitably ask me what would happen if I didn't get my daily fix. Would I have severe headaches? Would I go psychotic? Would I pass out at my desk? I suppose any of those things could happen, but I'm not about to find out, and here's why:

Coffee: The New Health Food?

So there! 🙂
