Default window management scheme in Mac OS X is not well-polished. For example, till Mac OS 14.6, there is no way to make an application occupy left half of the screen or to make an application always stay on top. To improve on that, my personal setup includes following applications. Better Touch Tool - At the most basic level, it provides “Window snapping” feature, drag the window to top-left and it expands to full screen. It allows full control of gestures and keyboard shortcuts. My personal setup includes “cmd + option + Tab” to switch between active windows of the same application. It is available via homebrew cask. ...

For android projects, some engineers use Android Studio (new), some use Eclipse with ADT (old), few like me still savor command line, this blog post is about handling (building, installing and testing) android projects from command line. To create android project Sh 1 2 $ android create project --target 4 --name TestAndroidApp --path ./test_android_app --activity Main --package net.ashishb.TestAndroidApp --gradle --gradle-version 1.0.+  ... After changing to directory test_android_app (cd test_android_app), fix a bug ...

A useful and handy command specially when you during experimentation, you are stuck because of a changing language settings to an undecipherable foreign language. Bash 1 adb shell am start -n 'com.android.settings/.Settings\$LocalePickerActivity'

Android plugin for Gradle does not support Java-style compile time only dependencies. After spending a few hours on trying to build android app targeted for Amazon SDK (without using Amazon’s Android specific plugin but just their jar stubs for maps, ADM and Home widget), I finally found that the one way to support compile-time dependencies is following. For application project Groovy 1 2 3 4 5 6 7 8 9 10 11 12 13 configurations { provided } dependencies { // ... provided fileTree(dir: "${project.rootDir}/path_to_libs_dir", include: '*.jar') } // Android's version of sourceSets.main.compileClasspath android.applicationVariants.each { variant -> variant.javaCompile.classpath += configurations.provided } For the library project Groovy 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 configurations { provided } dependencies { // ... compile fileTree(dir: 'libs', include: '*.jar') provided fileTree(dir: "${project.rootDir}/patch_to_libs_dir", include: '*.jar') } android.libraryVariants.all { variant -> // Exclude the jar files from making its way into the final apk. // Irrespective of what the path_to_libs_dir is the final jar files end up in libs dir. variant.packageLibrary.exclude('libs/lib1.jar') variant.packageLibrary.exclude('libs/lib2.jar') // ... } References https://stackoverflow.com/questions/16613722/gradle-configurations-not-working-as-expected-in-new-android-build-system https://stackoverflow.com/a/24157721

Booting process The bootloader loads the kernel stored in /mach_kernel. Tip: Use rEFIt as a bootloader for dual booting into GNU/Linux. Kernel launches the launchd process which is equivalent of init in GNU/Linux. launchd loads startup processes from several directories (/System/Library/LaunchAgents, /System/Library/LaunchDeamons, /Library/LaunchAgents, /Library/LaunchAgents and corresponding files in ~/Library directory)

I was trying to make some modifications to android emulator and was unable to find good set of instructions for the compiling the same. Here are mine. Bash 1 2 3 4 5 6 7 8 9 10 11 12 13 14 # Get the source code. git clone https://android.googlesource.com/platform/external/qemu cd qemu # Install required dependencies. sudo apt-get install gcc-multilib libesd0-dev libx11-dev \ libxext-dev libasound2-dev libpulse-dev \ lib32stdc++-4.8-dev # Install ia32 libraries (missing from default ubuntu 13.10). sudo apt-get install libgtk2.0-0:i386 libpangox-1.0-0:i386 \ libpangoxft-1.0-0:i386 libidn11:i386 libglu1-mesa:i386 # Configure and build the emulator binary. ./android-configure.sh --no-gles --no-tests --cc=/usr/bin/gcc make -j16 # The emulator binaries are in objs directory.

As the title suggests, I was looking for a way to send HTML mails in python using Amazon SES but did not find anything (or maybe my search skills are bad). So, once I found the solution, I thought I might share it with everyone. The basic idea is that contents of the mail (raw-message) must be a JSON dictionary with “Data” as main key whose value is a key value pair containing entries with keys like “From”, “To” etc. Sample code can be seen below.

This blog post is a HOWTO guide for using github while collaborating during hackathons. It does not cover git in detail.

This blog post contains a collection of small tips for engineers migrating from GNU/Linux to Mac OS X for software development. Note: In another post, I wrote about why there is a dearth of a good GNU/Linux laptop.

Some experience with adb and fastboot preferred (they are part of android SDK)
