To create a short cut and pin it to the task bar in Windows 7 do the following:
A quick one-liner for counting the number of characters in a given field for each line in an ASCII file.

The first thing to know is that by specifying n number of -hivevar key value pairs when invoking hive on the command line will allow you to pass that data into the hive process.
For example, if you do the following
$ hive Even though the ADT bundle provides a 64 bit version, the system requirements indicate that “64-bit distributions must be capable of running 32-bit applications.” I failed to see that when installing it under Fedora Core 20 and was getting the following error from Eclipse:
Error executing aapt: Cannot run program "/home/rchapin/sdks/adt-bundle-linux-x86_64-20131030/sdk/build-tools/android-4.4/aapt": error=2, No such file or directory: error=2, No such file or directory android_sdk line 1 Android ADT ProblemI checked to see if the file was there. Yep. I → Continue reading “Eclipse Android Development Error executing aapt: Cannot run program “/path/to/aapt”: error=2, No such file or directory: error=2, No such file or directory”
When setting up Eclipse for Android development, after you have installed the Develeper Tools and NDK Plugins and linked to the ADT-bundle and then imported your project (see othere posts related by searching for ‘android’) I got the following error:
[2014-03-24 14:14:53 - android_sdk] Unable to resolve target 'android-18'I went and checked to make sure that the Platform.MinPlatformToolsRev property in the ~/path/to/adt-bundle-linux-x86_64-20131030/sdk/tools/source.properties matched that of my project.properties file.
They were both 18. Eh? Why the error?
So, in Eclipse, → Continue reading “Setting up Android in Eclipse, Unable to resolve target ‘android-18’”
I’ve got a new install of Eclipse and am setting up to do some Android development.
After getting the Develeper Tools and NDK Plugins installed and linking to the ADT-bundle that I downloaded, I was getting an error when attempting to import the existing project by going to File > Import > Android > Existing Android Code Into Workspace.
The error was:
Invalid project description /some/path/to/project/dir_name overlaps the location of another project: dir_name
After a few searches and a couple → Continue reading “Invalid Project Description, project path overlaps the location of another project with the same name When Importing Existing Android Project in Eclipse”
I was having problems logging in this morning to my laptop. When I entered my password, it just hung. I pressed Ctrl-f2 to switch to an alternate tty, logged in as root and checked for errors in /var/log/messages.
Not seeing anything, I figured, I’d try and restart the Xserver. Still not being completely familiar with the sysctl paradigm it wasn’t obvious how to restart it.
So, as root, I simply switched the runlevel to 3, and then back to 5 → Continue reading “Restarting XServer in Fedora 20”
I’m working on a project that includes sending data via Amazon Simple Storage Service (S3) and was having some problems configuring and using the s3cmd client.
The first thing I discovered about s3cmd is not to trust what it tells you when invoking s3cmd –configure to get things set up to use the bucket.
$ s3cmd -v --configure s3://some-bucket/some-prefix/

Access We recently got a new ASUS laptop for the boys to use (I’ll use it too, it’s pretty sweet) which came with Windows 8.
It did not come with the install CD or license key, but included a recovery partition and the key in the BIOS. Now that we’ve had it for a few weeks and verified that all of the hardware works, we are going to put Ubuntu on it, but I wanted to make sure that I would → Continue reading “Clone and Backup a Bootable USB Drive”
If you have a long-running command on shell-script that you want to generate a beep upon completion on your PC running Linux do the following:
Make sure that the pcspkr module is loaded:
# modprobe pcspkrThen create a wrapper shell script that looks something like this:
#!/bin/bash
# Some long running command here . . .
echo -e '\a' /dev/console
