Ken Shirriff did an amazing teardown of an Apple iPhone Charger. If you’re like me and enjoy reading in detail about how electronics are engineered, you’ll really enjoy this one. Citations and all. The real takeaway is that it’s a very high quality product both in terms of build quality and design. That’s pretty typical […]

Someone is very obsessed with building the USS Enterprise. Not the Navy’s carrier USS Enterprise, the Star Trek one. It’s actually pretty interesting to read. While it seems very improbable given the costs and the uncertainty, it’s interesting since we are at the point where a roadmap technically would make sense. It’s ambitious and who […]
Just the other day Microsoft announced it was going carbon neutral. Apple is now goaling for 100% renewable energy for it’s data centers by 2013. This is a very different goal than Microsoft, but still quite interesting. Apple is a much more focused company than Microsoft. I could be wrong, but I doubt they are […]
This is a pretty interesting presentation. The content matter while slightly silly is actually pretty informative and eye opening. I bet we all waste more paper than we realize. What really stands out is Joe Smith has amazing presentation skills. This should be shown on the first day of any public speaking class. This is […]
It’s no secret that I’m a keyboard snob. After all how many others have written several blog posts about keyboards. I’m rather disappointed to see Lenovo getting rid of the classic keyboard. Lenovo (previously IBM) ThinkPad had the best keyboards of the PC laptops. There was no competition. Apple managed to achieve a decent “chicket […]
When you ssh into another box from Mac OS X, X11 automatically starts up because X11 forwarding is enabled by default. I have no idea why it’s a default as I suspect the vast majority of Mac OS X users never use X11 forwarding. It’s annoying to need to quit it every time. The fix […]
Gizmodo has a great essay on how Yahoo killed Flickr. I think this excerpt is a pretty good summary: It was a stunning failure in vision, and more or less the same thing happened at Flickr. All Yahoo cared about was the database its users had built and tagged. It didn’t care about the community […]
About two weeks ago I got to see Shuttle Enterprise Arrive in NYC. NASA Television has now posted some video of the Shuttle being unmated from the 747 Shuttle Carrier Aircraft. Unlike most of the times we’ve seen this process it was done by crane.
I was seeing this error after installing ant on CentOS 6.2 via yum: $ ant Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher Caused by: java.lang.ClassNotFoundException: org.apache.tools.ant.launch.Launcher at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) Could not find the main class: org.apache.tools.ant.launch.Launcher.

This blog is now up and running on a newer faster server. I’ve spent a fair amount of time over the past week moving sites and syncing databases as I transition things over. Still some loose ends, but I’m mostly there. Back to regular blogging tomorrow.
