Random MongoDb Syntax: Updates
- by Liam McLennan
I have a MongoDb collection called tweets. Each document has a property system_classification. If the value of system_classification is ‘+’ I want to change it to ‘positive’. For a regular relational database the query would be: update tweets set system_classification = 'positive' where system_classification = '+' the MongoDb equivalent is: …Read the article

How can I exclude content in my notifications bar from being indexed?
- by Liam E-p
Of course I want my content to be indexed pretty fast by search engines, however not my notifications bar. My notifications bar contains the last 30 changes to content on the site, and I don't want this to show in my SEO meta. As all the notifications are generic, it often doesn't provide any relevant information. As I said the notifications…Read the article

Investigating Strategies For Functional Decomposition
- by Liam McLennan
Introducing Functional Decomposition Before I begin I must apologise. I think I am using the term ‘functional decomposition’ loosely, and probably incorrectly. For the purpose of this article I use functional decomposition to mean the recursive splitting of a large problem into increasingly smaller ones, so that the one large problem may be…Read the article

Many thanks to Andy Westgarth and his team for organising a fantastic conference at the rather elegant Bradford University School of Management. Also, a big congratulations to all the delegates who gave up there free time to come and hear us speak and who were, in general, enthusiastic and asked some cracking questions to keep us speakers on…Read the article

Using Query Classes With NHibernate
- by Liam McLennan
Even when using an ORM, such as NHibernate, the developer still has to decide how to perform queries. The simplest strategy is to get access to an ISession and directly perform a query whenever you need data. The problem is that doing so spreads query logic throughout the entire application – a clear violation of the Single Responsibility…Read the article

How should I store a Game Database on Android?
- by Liam
I'm looking at creating a game for Android and while I have most of the ins and outs worked out, the one thing I'm struggling with is how to store data for the game. Ultimately, the game will be based off of a lot of pre-defined data and statistics so the obvious choice to me would be something like SQLite, but as I'm pretty new to the…Read the article

Last chance to see ... Virtualisation for Developers at NxtGenUG Cambridge, Tuesday 14th December
- by Liam Westley
As a farewell to 2010 I'm also saying farewell to presenting my Virtualisation for Developers and Hyper-V for Developers presentations with a final outing at NxtGenUG in Cambridge (my first visit to a user group in The Fens). I may have some homemade nibbles and party stuff to liven up the evening, and a certain Rachel Hawley…Read the article

Optimising website IP for location
- by Liam Sorsby
From my understanding of SEO, websites are optimised for the current location of their IP address. For example if xxx.xxx.xxx.xx resolves to the UK then you are more likely to get higher rankings in the UK then you are in the USA. However, my query is when you use a CDN you are storing a cached version of your website across multiple…Read the article

Unnamed Refactoring
- by Liam McLennan
This post is a message in a bottle. It cast it into the sea in the hope that it will one day return to me, stuffed to the cork with enlightenment. Yesterday I tweeted, what is the name of the pattern where you replace a multi-way conditional with an associative array? I said ‘pattern’ but I meant ‘refactoring’. Anyway, no…Read the article

Handy Javascript array Extensions – contains(…)
- by Liam McLennan
This javascript adds a method to javascript arrays that returns a boolean indicating if the supplied object is an element of the array Array.prototype.contains = function(item) { for (var i = 0; i < this.length; i += 1) { if (this[i] === item) { return true; } } return false; }; To test…Read the article

Twitter Customer Sentiment Analysis
- by Liam McLennan
The breakable toy that I am currently working on is a twitter customer sentiment analyser. It scrapes twitter for tweets relating to a particular organisation, applies a machine learning algorithm to determine if the content of tweet is positive or negative, and generates reports of the sentiment data over time, correlated to dates,…Read the article

Command Query Separation
- by Liam McLennan
Command query separation is a strategy, proposed by Bertrand Meyer, that each of an object’s methods should be either a command or a query. A command is an operation that changes the state of a system, and a query is an operation that returns a value. This is not the same thing as CQRS, hence why I think that CQRS is poorly named. …Read the article

Learning PHP from beginner to advanced

I've dabbled with PHP for a few years now and I'm capable of most of the basic things, building login forms etc but from my time on here I've noticed there's so much more I need to learn, like best practices, security issues etc and so I want to learn everything from the very basics. In the past I've used forums and browsed the web…Read the article

What ‘enterprise’ doesn’t understand about risk
- by Liam McLennan
Enterprises (large bureaucracies) obsess about risk. I think it is because of the inertia generated by the process and politics that they have to deal with. The trouble is that they respond to risk in precisely the wrong way: by adding complexity. Need to call a method? Better wrap it in WCF service. Need to talk to another…Read the article

how do I make my Dualshock 3 gamepad work in Ubuntu 14.04?
- by user290527
When my desktop computer was running Ubuntu 12.04, my PS3 controllers would work with USB. I didn't need to do any special setup. I could just plug it in before I start SuperTuxKart and it would recognize it. I can also do this on my laptop (still running 12.04). Since I gave my desktop a fresh install of Ubuntu 14.04, the…Read the article

Is it possible to damage a CPU so that it works, but only at high temperatures? My Phenom 2 1090T is idling at 50°C and I have tried everything to get it down. I can play Deus Ex HR, Arkham City, or Dirt 3 and it hovers around 60. I have cleaned out all my fans: 2 intake (front and side), 1 exhaust (Arctic Freezer). My…Read the article
