Add An Existing Local Git To

Git is a great way to manage different versions of your code during development. I use it on my local machine when developing on my own but occasionally need to start working with others. This is a step-by-step description of how to upload a local git repository to for sharing and collaborating.

Useful Git Commands

I've made several posts about git as I was learning to use it. This is a list of all the useful commands I found in the form of a cheat sheet.

Intro to Git Version Control

This is a simple story to illustrate how to do basic revision control with Git. I've had a couple of nightmares with Git repositories - it has been a bit of a git getting my head around how it works.

If you don't know what Git is, it's distributed revision control and source code management (SCM) system.  It's widely used to share open source code and is great for managing your code base with speed and, if you pay at private.

Uninstalling Linux Packages

Advanced Package Tool (Apt) is one of the programmes that make Linux such an awesome operating system.  It allows you to install any of 1000s of libraries, commands, tools and applications and Sourceforge have a good introduction for this.  However there is little info about how to uninstall anything and clean up properly. Vast amounts of hard-drive space can be taken up by files left over after an uninstall.  This post gives you the information to thoroughly uninstall programmes and any extra dependencies that came with them. Keep your Linux machine as clean as Mr. Clean!

Raspberry Pi Motion Detection Security Camera

We have weekly deliveries of meat or vegetables to our home that are left outside our house if we are not there to receive them.  Although they are only there for a few hours and hidden behind some planters someone noticed them and started stealing them. I decided to catch them by using a Raspberry Pi to make a really cheap security camera.

Get started with Git: Cloning

Git is a software version control system.  It is good because you can use it in a distributed way keeping local and remote repositories kept in sync, with multiple developers strong project history and conflict resolution.

This post describes how to 'git going' with an existing project assuming you have already Set Up Git.  We create a local version of a project on github, make a small change and bounce that back to the github master.

Unhide Android Developer Options

I recently bought a Samsung Galaxy S4 Mini with Android 4.2.2/Jellybean. I routinely use my phone for development purposes requiring access to Android Developer settings. Out of the box these options are hidden and you need to know how to reveal the options.

Go to Settings, More..., About Device. Tap on Build number 7 times.  You will get a little toast popup window letting you know developer options are enabled.  They can be accessed from the More... menu.

Accessing JSON Stored in NSDictionary

I'm still learning to be a developer... and probably always will be.  It helps me to write blogs about code that I manage to get working. I've written an app that uses OAuth to access a JSON input from the web and parse it. This post describes some of the new stuff I learnt on the way, specifically about parsing JSON and accessing NSDictionary.

Leap Motion Special Applications Restricted in SDK T&Cs

In the post about my #FirstLeap with the Leap Motion 3D Motion Controller I thought there would bparticularly interesting applications in point of sale kiosks, controls for video DJs/lighting at live events and corporate presentations/collaboration.  The Terms and Conditions of using Leap Motion's SDK require a special agreement for these types of use; I hope that this doesn't stop the use of Leap Motion through overcharging or excessive red tape.

Leap Motion 3D Motion Controller

The new Leap Motion controller arrived on 24th July 2013 a couple of days after launch after months of waiting.  I was pretty excited by what this 3D Motion Control device could do.  This is a record of my first couple of hours of life with Leap Motion.

Add another HDD to Ubuntu Server

Setting up a home server running Ubuntu Server operating system provided a foundation for lots of cool stuff like setting up a web server.  I wrote about this experience in a previous post Playing Around With Linux A Server.  This post is about adding another harddisk to the server under Ubuntu Server using the command line.  No easy GUI here!

Using Drush to sync live and dev Drupal websites

This post describes how to use Drush to synchronise a live drupal website with a local development copy and vice versa, to synchronise an updated dev site back to the server version.  Following on from previous posts about Drupal this blog assumes that both a live server-based and a local drupal website are in place.

Set-up Multisite Drupal 7

In order to develop my website using Drupal I wanted a local version to work on off-line and a live version to periodically update with releases.  This post continues to tell how I achieved that by describing how to create a multi-site drupal installation having completed setting up Drupal 7 and AMP on my Mac OSX Lion.

Clean Up your Dirty URLs in Drupal

Having installed Drupal, the website building Content Management System (CMS), on a cloud server I had some issues getting Clean URLs to work.  This post describes how I got rid of my dirty URLs for Drupal hosted websites.

Dirty URLs

Default URLs for a Drupal hosted site include ?q= e.g. because it triggers a database query for what's after the ?q=.  Removing these characters, or at least not displaying them in the URL makes search engines friendlier towards your site and may increase your page's rankings.  A further step is to add aliases to pages so there is a human readable name instead of an id e.g. instead of

Drupal basic concepts

Oh wow - Drupal as expected has a steep learning curve!  Once I'd installed it on a cloud server, here's what I first learned while clambering up the learning curve.  I've also written posts about specific (and general) stuff I've done with drupal.

Fire up your Raspberry Pi

I was loaned a Raspberry Pi.  It was brand new and still in its box when I got it.  This post is about how I breathed life into it. There are two main jobs to do: preparing an SD Card to be the Raspberry Pi's hard-drive and complete the initial setup.

I used my MacBook Air to do this so the process is Mac specific in some areas i.e. using Terminal.

Pibow: The Raspberry Pi Case

I didn't like having my much prized Raspberry Pi (loaned to me by a good friend) resting on a cardboard box looking cool but vulnerable to my quite regular drink spills and clumsy dropping of heavy and/or pointy items.  I wanted a box to put it in - so I got one.

Self-employed poacher?

Poaching is where you 'steal' work from your employer by going direct to the client.  This is good because you get more work; this is bad because you annoy those that employed you and kills off opportunities for future work with them.

I am self-employed but only for a very short time - I have learnt so much during this first year. One of the most difficult things to get to grips with was not poaching work from others while proactively seeking much needed work.  I'm still not sure I got it right.
