Hatem Mahmoud's Thoughts

Principal Project Manager at Microsoft

[hatemmahmoud]

People who know me professionally know that I'm passionate about Product Management. I truly believe that, done properly, a strong product leader acts as a force multiplier that can help a cross-f...

3 responsibilities of a great product manager:

Responsibility #1: Product Strategy

Quite simply, it’s the product manager’s job to articulate two simple things:

What game are we playing?

How do we keep score?

Responsibility #2: Prioritization

The question isn’t what is the best list of ideas you can come up with for the business – the question is what are the next three things the team is going to execute on and nail.

Place your feature concepts in one of Three Feature Buckets:

Customer requests

Metrics movers

Customer delight

For large, monolithic releases of features, optimal success comes from packaging up items from each of these buckets.

Responsibility #3: Execution

Product specification

Edge case decisions

Project management

Analytics

Installing CyanogenMod 11 (Android 4.4.4 KitKat) on LG Optimus 4X HD P880

UPDATE (2014-09-17): Finally, a milestone snapshot (cm-11-20140916-SNAPSHOT-M10-p880.zip) has been released. I got a notification on my device, clicked Upgrade, and it worked like a charm.

Download the CyanogenMod package for your device to your computer and copy it to your device. For me, that was cm-11-20140805-NIGHTLY-p880.zip

Download Google Apps for CyanogenMod 11 and copy it to your device. For me, that was gapps-kk-20140606-signed.zip.

On your device, head to Settings > Security and enable “Unknown sources”.

On your device, head to Settings > Developer options and enable “USB debugging”.

Install SuperSU app on your device. It will pop-up when you start a root-only app and you’ve to hit the Grant button to provide root access to that specific app.

Root your device with one of the following methods:

The easy way, on Windows using Kingo

The hard way, following this guide

You can use the Root Checker app to verify your device is rooted.

Unlock the bootloader of your device:

Download and install Android SDK to your computer (any platform)

Connect your device to the computer through USB

Open a terminal or command prompt window in the folder which contains adb and fastboot executables and type “adb reboot oem-unlock”. Here is the output on my Mac:

~/Applications/Android Studio.app/sdk/platform-tools$ ./adb reboot oem-unlock * daemon not running. starting it now on port 5037 * * daemon started successfully *

Your device will reboot

Download and install ROM Manager app to your device

In ROM Manager, select “Recovery Setup”, then choose to install “ClockworkMod Recovery” and follow the steps to confirm your device model until you get the message “Successfully flashed ClockworkMod Recovery”.

In ROM Manager, select “Reboot into Recovery” mode, and connect the device to your computer through USB.

In ClockworkMod Recovery mode, use the physical volume buttons to move up and down and the home button to confirm menu choices, select “backup and restore” to create a backup of your current ROM, then select “Wipe Data / Factory Reset”.

Move CyanogenMod and Google Apps packages to your device using an SD card or using adp as explained here: http://wiki.cyanogenmod.org/w/Install_CM_for_p880

In ClockworkMod Recovery mode, select “Install from zip” and browse to the CyanogenMod package.

Once installation has finished, return to the main menu and select “Reboot system now”. The device will now boot into CyanogenMod.

To install Google Apps, reboot in ClockworkMod Recovery mode again, select “Install from zip” and browse to the Google Apps package.

Enjoy KitKat!

Git Autocompletion and Status Prompt in Terminal

To get autocompletion of Git subcommands, branch and tag names, etc. in your Terminal, just download git-completion.bash, that comes with Git, to somewhere (e.g. ~/.git-completion.bash) and update your .bash_profile as follows:

# git autocompletion source ~/.git-completion.bash

And to see repository status in your prompt, just download git-prompt.sh, that comes with Git, to somewhere (e.g. ~/.git-prompt.sh) and update your .bash_profile to something like this:

# git prompt source ~/.git-prompt.sh GIT_PS1_SHOWDIRTYSTATE=1 GIT_PS1_SHOWSTASHSTATE=1 GIT_PS1_SHOWUNTRACKEDFILES=1 GIT_PS1_SHOWCOLORHINTS=1 GIT_PS1_DESCRIBE_STYLE="branch" GIT_PS1_SHOWUPSTREAM="auto git" PROMPT_COMMAND='__git_ps1 "[\t] \u@\h:\w" "\\\$ " '

More details and other options are explained in both files.

Ruby on Rails on OS X Mavericks

So you just clean installed OS X Mavericks and want to quickly setup your Ruby on Rails development environment. Mavericks comes with Ruby 2.0.0p247 preinstalled, but we need a version manager to be able to use multiple versions. Here is how I did it in 30 minutes:

Just enter git, or any command that requires Xcode Command Line Tools, in the Terminal and Mavericks will alert you. Just click Install to download and install them.

Configure git:

$ git config --global user.name 'Hatem Mahmoud' $ git config --global user.email '[email protected]' $ git config --global credential.helper osxkeychain $ git config --global color.ui true

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)" # check it: $ brew doctor Your system is ready to brew.

Install rbenv and ruby-build:

$ brew install rbenv ruby-build # enable shims and autocompletion: $ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

Restart your shell so that PATH changes take effect:

$ type rbenv rbenv is a function

Install Ruby:

# list all available versions: $ rbenv install -l # install a Ruby version: $ rbenv install 2.0.0-p247 # set the global Ruby version: $ rbenv global 2.0.0-p247 $ rbenv versions system * 2.0.0-p247 (set by /Users/hatem/.rbenv/version)

Update RubyGems:

gem update --system

Install Bundler and Rails gems:

gem install bundler rails

Setup PostgreSQL:

# install postgresql brew install postgresql # create a database cluster initdb /usr/local/var/postgres -E utf8 # serve that database postgres -D /usr/local/var/postgres # install the postgres gem (including ARCHFLAGS is recommended): ARCHFLAGS="-arch x86_64" gem install pg

Install ImageMagick:

brew install imagemagick

Download and install Anvil.

Enjoy!
