All you have to do is configure two protected variables you extend on the class, so here is an example ORM model…

You could also add a method on the Pie class for something like getSizeOfSlice() and that would calculate the size of each slice based on $this->pie_size and this->pie_pieces which is useful to separate out data manipulation from the Controller which should happen in the Model.

If anybody is interested in trying it out before I put it on GitHub and help me find bugs, then please comment or drop me an email tarnfeld[at]me.com :-) Thanks!

You can get it on GitHub if you fancy using it!

I’m quite happy with them, enough to get me into my College course so thats great! So glad its all over!

The one thing you don’t hear much chatter about is, in my opinion the extraordinary battery. I’m writing this from the word press ipad app, and I’m currently sitting happy with 71% battery. It’s 5:15pm and I used my iPad on the train to France – 2.5 hours, and used it to take notes for 3 hours, then played with it for the last hour and I charged it once, this morning at about 6am!

I think one thing apple did well if it not be the extraordinary iOS they have built for this device and the apps that developers ares building, but its the care and attention into the details nobody thinks about – like battery life.

Im glad I invested the extra money in the 3G model as its nice to be connected, wherever!

That all I have to say about this exceptional device, so if your thinking about buying one, just go buy one… Now.

PS: WordPress for iPad is an awesome app!!

They are considerably cheaper than the retail price so its worth the buy! Excellent books if you ask me, got me going developing for iPhone!

The usual functions like cmd+c/v/x work for cut, copy and paste. Also the cmd+a and enter key work too! The brightness up and down keys actually turn the iPhone brightness up and down and even the music controls work!

It would be nice if Apple provided some kind of external keyboard events so you can tie buttons and code to key combinations like cmd+n and cmd+s for apps, but I doubt that will come.

Anyway, if you have iOS4 and an apple wireless keyboard, pair it up!

Step 1
Find a suitable location whereby you can attach your headphones in the dangly position.

Step 2
Get two pens (preferably with clippy bits) or even something else you can attach things onto and affix these miniature weight like devices to each earbud of the iPhone or iPod  headphones.

Step 3
Attach the inserty end (headphone jack) to the top of your location whereby you can attach your headphones in the dangly position and confirm to yourself they are hanging straight. There is an iPhone app for this if you fancy it.

Step 4
Go back to your headphones after leaving them untouched for at least 24 hours and then remove the weights.

Step 5
Detach your headphones from the affixed upright dangly position and insert the inserty end into your iPhone, iPad or iPod.

This may seem a joke… but a very helpful lady on the Apple Store Chat told me this, at first I thought she was making fun of me when I asked her how to straighten them and then I tried this…. BAM.

What is it?
Basically, it’s not fun nor easy to setup a push notification system for your iphone app to get push notifications from your server. There are complicated tutorials, but they make sense to nobody!

All the user has to do is sign up, and enter their iPhone Developer Center push notification stuff and then they can access the sites API by sending requests that include the data of the push, and their API key.

I haven’t looked deeply into the push notifications API from apple yet but I have a feeling this could work.

If you have any ideas, faults or want to build it, let me know if you are going to and I would love to test it :)

So, I have knocked up a nice little demonstration / how-to kind of tool that is covered in comments in the code to make sense of what was going on. You can get hold of it here on github or take a look at the demo on my site. Feel free to fork me on github if you have any new ideas for the tool.

If you find any bugs or think something could be explained better, shoot me an email or reply (@tarnfeld) me on twitter and i’ll be happy to help :-)

Hope this helps out some developers and gets them integrating this really awesome service into their awesome apps!

P.S. The service is invite only so you may have to request access from @pusherapp if you don’t already have an account.

It’s going to be built using Code Igniter purely because of the ease of development and the nice URL’s and development tools it includes.

It probably wont start development for a few weeks yet stay tuned here or on my twitter (@tarnfeld) for news and updates on the projects. I mind mapped the ideas of what the web app will include, if you have anything else you think it should, drop me an email to tom@tarnfeldweb.com.
