Cicadas Attack!

Well, I've experienced the 13-year cicadas that I've heard so much about. In Middle Georgia yesterday as soon as I opened the car door I was greeted by an almost deafening, hard to describe sound coming from the trees. It sounded like the summer cicadas I've always known, but louder and sharper.

They also filled the air. You could look up and see them constantly criss crossing the sky. Two or three flew into my face and hair.

It seemed like they'd taken up residence in every tree and bush in sight, but the rumors of the bugs eating every bit of vegetation in sight turned out to be unfounded.

Dark Energy Is Driving Universe Apart

NASA's Galaxy Evolution Explorer Finds Dark Energy Repulsive from Science Daily.

The findings offer new support for the favored theory of how dark energy works -- as a constant force, uniformly affecting the universe and propelling its runaway expansion. They contradict an alternate theory, where gravity, not dark energy, is the force pushing space apart. According to this alternate theory, with which the new survey results are not consistent, Albert Einstein's concept of gravity is wrong, and gravity becomes repulsive instead of attractive when acting at great distances.

The First Hour or Two with the Cr-48

So, I've been using this ChromeOS notebook for a couple or three hours now.  Most things work fine.  I've done the usual email and documents work in Gmail, made a couple of phone calls using Google Voice in Gmail, and played a couple of screens of Angry Birds.

Right now I'm listing to music on Amazon Cloud Player.

Connecting to wifi was very simple.

Mouse motion, famously problematic on this hardware, was a little flaky when trying to play Angry Birds, but otherwise I don't notice much problem.  I finally found the check box to enable tap to click, so that is all better now.

I found the terminal with ssh via Ctl-Alt-T and tried it out.  It works but, again, wide-screen insanity prevails.  Also the font and colors need to be fixed in the terminal.   It's a limited set of commands but ssh is really all I'd need.

Right now it's on the charger and has charged up to 78%.

Using a Cr-48

This is my first blog post and my first user session with a Cr-48 running ChromeOS.

Everything is great so far except for one thing:   The windows are all full screen.  That's about the most annoying thing I could think of.

Otherwise, everything is working pretty well with almost no problems.  I like the size, form factor, weight and even the keyboard so far.

Tidal Energy In the UK

Fascinating.  They have tidal energy generators in the UK as reported by this article by Chris Goodall in The Guardian.  I find it amusing that they call the energy “renewable” when it's really depleating the angular momentum of the earth's rotation and the moon's orbit.

Still, as far as I can tell, renewable always means a big enough supply that we can't imagine when we'll run out. That's the way new energy supplies often start out.

Projection on 26-Story Coca-Cola Building

For it's 125th anniversary, Obscura Digital arranged to turn Coca-Cola's 26-story headquarters building in Atlanta into a giant, four-way projection screen.

From The Street:

The entire Coca-Cola North Ave. tower in Atlanta—26 stories high and 402 feet (122.8 m) high—is canvassed in scrim.

The projection covers an area 339 feet high and 157 feet wide per side of the building.  The projection surface area from all four sides of the building totals more than 210,000 square feet, making it the world’s largest single building illumination. 

This display uses 45 projectors that are 20,000 lumens each, for a total of nearly 1 million lumens of light simultaneously projected onto the building.  The overall projection resolution is more than 7,000 pixels wide (7040 x 3800).

Paper Computers

I remember an interview with someone from Xerox PARC, probably almost 30 years ago, where they were talking about ubiquitous computers that were like paper.   I remember a quote that went something like, You'd just tear a new computer off a pad when you needed one.  They'd just be laying around your office in piles.

Well, they seem to be here, as reported in this article in The Economic Times.

Cloud Computing

Seth asked about our sightings of and thoughts on cool, emerging technologies.

I continue to hold that the technology that promises one of the most significant impacts is cloud computing.  It's been coming for a long time but cloud computing has recently turned one of those corners and it's influence is rapidly accelerating.

Basically, cloud computing means that your data and your applications are out on the Internet, “in the cloud” as we say.

I've been moving my own work into the cloud and I'm probably following that acceleration curve pretty closely.  Here's my current score card.

I've been a user of web-based email since Rocketmail and Yahoo's re-branding and evolution of the same when they both took off around 1997.  For years I merely echoed email into the cloud, keeping my own personal copies on an email server at home.  Sometime around the introduction of Gmail, I stopped keeping my own copy and  switched wholesale to Gmail.

I've been using Google Documents in earnest since 2006.  Since then, probably 99% or more of every document or spreadsheet I've created, including home and work, have been in the cloud.  I added slide presentations to that in 2007, and drawings most recently.  (Note that I've still not found a replacement for Windows Paint, though).

In 2006 I moved my blogging off of my own server and back to Blogger and Blogspot.

For the past several years I've been putting more and more pictures in Picasa, though it's not my sole storage medium in that category.

In the fall of 2009 I became a user of GTD and moved my next action lists and projects to Gmail Tasks.

Over this past year, my move into the cloud has gone mad.

I've used Piknic solely for photo editing.

I've migrated all of my note-taking into Google Documents.  Many folks will remember the blue notebooks I used years ago, inspired by my old friend Leonard's use of them for journals when we were at Georgia Tech.  For a number of intervening years I moved most of my note-taking into on-line text documents edited with Emacs.  Over this past year I've migrated almost 100% of my note-taking on-line into Google  Documents.  I create several new documents every day.

Also this year I made the conscious decision to start migrating all of my media consumption into the cloud and at the same time, decided to get a Roku box instead of a Blueray player.  I use Netflix and Amazon, and occasionally Dish on Demand, for movies, Kindle for books, and Amazon, Pandora and Slacker for music.  My thought is to never again purchase physical media.

I've moved most of my own little command-line utilities into AppEngine equivalents.

I've also become a recent user of Dropbox for file sharing.

The personal Linux “main machine” that I use at work for programming has been a virtual machine for the recent few months.  The next (final?) frontier, for which I'm waiting with poised fascination, is a browser-based integrated development environment for writing, testing and running the computer programs I write daily.  A lot of work is underway and there are some initial results out there now.

I'm late to this ballgame, but I'm also getting ready to move my backups to Carbonite.  That will probably be another case of just putting a copy there, while maintaining other current schemes.

I'm already at the point that I can do almost any thing of significance I do on a computer from any computer that I truly trust.

Finally, the Voice of Reason Regarding Aid to Japan

From The Economist article After the Quake.

From the article:

What you shouldn't do is give money to charities that are raising money off the disaster. The New York Times' Stephanie Strom explained why last month:

[W]ealthy Japan is not impoverished Haiti. And many groups are raising money without really knowing how it will be spent — or even if it will be needed. The Japanese Red Cross, for example, has said repeatedly since the day after the earthquake that it does not want or need outside assistance. But that has not stopped the American Red Cross from raising [tens of millions of dollars] in the name of Japan’s disaster victims.
