Hi, thanks for visiting!

My name's Sam Kelleher, and I am a Senior Full-Stack Web Developer / Software Architect based in London. This website mostly contains a sample of work from my portfolio, tips, and best practicies for building web applications, and reviews + photos of food and hotels in London.

Backbone + Marionette GitHub Repository List - Sample Application

Backbone + Marionette GitHub Repository List - Sample Application

Sometimes the best way to learn something is to study each component separately, this gives us a true in depth skill on how something specific works. However, putting these components together to make a full featured application is another ball game entirely. I've always maintained that Software Engineering isn't difficult, but it can be complicated - as a typical application will consume numerous different technologies from development stages, to deployment, to runtime. It's putting all these modules together that is the hard part. Read more...

Dictionary Based Password Generator - Cross-Platform Chrome App

Dictionary Based Password Generator - Cross-Platform Chrome App

I've built a pure JavaScript Chrome App that generates random dictionary based passwords that are strong and memorable; which you copy to your clipboard to use. Thanks to the Chrome environment, it's multi-platform and can run anywhere Chrome can (Windows, OSX, Linux, Mobile) and appears as a Native application. Read more...

ASOS中国 - Hybrid iOS and Android eCommerce App

ASOS中国 - Hybrid iOS and Android eCommerce App

Stared this project from scratch in Spring 2015 for a London based agency on behalf of their client ASOS China. Following a similar design to the UK iOS app, this Cordova powered runs on both Android and iOS devices, in both orientations, on both mobile and tablet.Making pure JavaScript single page applications is one thing, with it's own set of complexities and challenges; but doing the equivalent for a JavaScript app that will function only in a mobile environment brings with it an entire new set of challenges. These are specifically related to the user interface. The app still has to retain the gesture recognition and actions found in native applications, and perform will full buttery smooth animations expected from real applications. Read more...

GitHub vs BitBucket

When it comes to hosting our source-code, many platforms can cover the basic of hosting a central GIT repository for us.

GitHub charges per repository, while BitBucket charges by contributor.

Use BitBucket if:

  • You only work individually or in a small team (5 people or less).
  • You wish to have private repositories.
  • You wish to work with a large number of repositories.

Use GitHub if:

  • You project is open source.
  • You only have a small number of private repositories.
  • Many people will work on a repository (5 people or above).

As for the rest of the differentiation features, they're both pretty similar, with the one exception that GitHub is universally recognised and there are many tools, such as CI services, that can plug straight into GitHub by using your account; although BitBucket is gaining notability in this regard.

I do wonder about the long term viability of BitBucket offering private repositories, as surely the cost of doing so will increase over time - with storage costs in particular. Then again, the same applies for GitHub and its generous hosting of public repos.

At the end of the day you get what you pay for, there are a handful of good reliable paid for services that can offer the best of both worlds - such as Codebase HQ which has git and project hosting for a small monthly fee, they charge by tiers of storage space used, users and number of projects - but each project can have unlimited repositories!

An idea is only as good as its execution.

Who is the voice of Google UK TTS engine?

The lady speaks with such authority an demand it demands me of voice of Corbin Dallas's' mother in the Fifth Element.

Where else do computers speak with regional accents in films? And not the universal one voice fits all as depicted in Star Trek.

CMS Gallery + GIF Support

CMS Gallery + GIF Support

A photo gallery within the admin console of a CMS I created called Leaf. The gallery components takes uploaded images, and creates all the required dimensions for the website. It supports creating WebP versions of all images, as well as the usual PNG, JPEG, types. PDFs are also converted to JPEGs. If a GIF is uploaded, the animation is preserved and rendered. The GIF is also undergoes some lossless compression to make the animation load faster. Read more...
