Matlab 7 under Windows 7

I had trouble getting Matlab 7 to work with Windows 7 RC even after setting the compatibility options. So, after a bit of search, here’s the solution (copied from ELFEHRIJ on with some minor changes).

After installing Matlab (use Classic Windows Theme if you have problems with the installer):

  1. To use Matlab with other windows 7 themes you have to change Java VM used by matlab.
  2. Download latest Java version and install it.
  3. Go to  <Matlab-installation-dir>\sys\java\jre\win32 you will find a folder named jre1.5.0_07 (or a similar version). Rename it to Original_<whatever was originally there>
  4. Go to C:\Program Files\Java you will find file named jre6. Copy it to <Matlab-installation-dir>\sys\java\jre\win32 and rename it to <original jre directory name>

This will ensure that Matlab uses the new JRE instead of the old one. Just start Matlab now!

Update: Thanks to “ra” and larry for the corrections.

Flashing Android Dev Phone 1

This tutorial is about flashing your Android Developer Phone 1 with your own custom build. It will provide a concise description of steps involved along with a special portion on how to port Google’s apps on your custom build. I found that particularly troublesome with little help on the Internet. So, that will be a bonus 🙂

First the disclaimer: This is for your Android Dev Phone 1 (ADP1). If you’re using T-Mobile’s SIM/firmware locked phone, stop. This tutorial is not for you. If you’re using ADP1, proceed at your own risk. You may brick your phone if you do something wrong and I shall not be held responsible for it. Finally, you might want to backup your factory-provided image. I don’t think it’s really necessary because you can just flash it again using the HTC provided images.

So, here is how it’s done:

Getting Started with Android Dev Phone 1

We received our Google Android Dev Phone 1 yesterday and immediately ran into trouble. We don’t have a supported carrier here and we couldn’t get our own carriers to work with Android because we didn’t have the APN information. Android’s distro that comes bundled into the Dev Phone won’t let you in without an APN  though. You get a “SIM not found” message and you can’t do anything other than dial an emergency number. So, after searching for a while, I found some useful tips for getting around the problem.

First, you need to plug in your phone through the provided USB. If you’re running XP, the device will probably not be recognized. (It wasn’t for me.) So, download the Android phone driver here (or here) and install it when XP asks to search for a driver. (Thanks to anddev for this information.) After that, get the Android SDK from here. Go to command prompt and navigate to the tools directory in the SDK. Then execute these commands.

adb shell
cd /data/data/
sqlite3 settings.db
INSERT INTO system (name, value) VALUES ('device_provisioned', 1);

Once the device finishes rebooting,

adb shell
am start -a android.intent.action.MAIN -n

Many thanks to Android Tricks for writing this tip.

Update 1: Android SDK ships with the latest version of the windows Android phone driver. You can find it in $ANDROID_SDK_HOME/usb_driver. So, you don’t need to download the driver using the links provided above.

Update 2: To get the Android device to work on Ubuntu 9.04 Jaunty Jackalope, you need to perform the following steps:

  1. sudo nano /etc/udev/rules.d/51-android.rules
  2. Add this line to the file: SUBSYSTEM=="usb", ATTRS{idVendor}=="0bb4", MODE="0666"
    (You can get the 0bb4 value from lsusb for High Tech Corporation (i.e. HTC) if you work with a different phone)
  3. sudo chmod a+rx /etc/udev/rules.d/51-android.rules
  4. sudo /etc/init.d/udev restart
  5. adb devices (to see the device)
