Now, a competing free library has popped up, complete with it’s own splashy launch page – SecureUDID.

The differentiation, is that SecureUDID uses a domain and a salt (basically a private token) to ensure that UDIDs are persistant, but private between Apps. Assumedly, a global UDID ‘salt’ and domain could be shared to provide a standard default UDID e.g. using all 1s for both. This is both a feature (from the user’s Point of View, and some developers) and a weakness from other developers’ points of view, however for what SecureUDID are trying to achieve, ubiquity isn’t required for them to prove useful to the developers that do choose to use them.

You can get SecureUDID source at GitHub.

Validating Apple App Store receipts for In App Purchase can be a pain, so I wanted an easy way to throw a receipt in and figure out if it was a valid or not.

So, I threw together a quick PHP script to figure this out quickly and easily; it takes a base64 encoded receipt as the input and will tell you if it is valid or not.

Give it a try:

The script is hosted at http://www.chrismaddern.com/validate-itunes-receipt/ and you’re free to use it – it will also take the url arguments receipt and sandbox to run without requiring input. If you would like to script it automatically as part of a deployment etc… I would ask that you host your own version, the code is available to download below:

Get the code

Update: this is now hosted on GitHub

Any forks / pull requests are more than welcome; I know the PHP isn’t exactly perfect!

I’ve settled on calculating the average exchange rate between the date the claim began, and it ends. To make this easier I’ve created a PHP page that calculates this given a start and end date.

You can find it over at http://www.chrismaddern.com/currency

Currently it works only with USD -> GBP, however the API has data for about a dozen currencies so I’ll implement more in the next few days.

Bug reports etc… in the comments.

You can also change the range of the checkboxes that are selected by changing the condition bounding ‘i’.

Select All Check Boxes on Page:

javascript:function check(){var c=new Array();c=window.document.getElementsByTagName(‘input’);for(var i=0;i<c.length;i++){if(c[i].type==’checkbox’){c[i].checked=true;}}}check();

Deselct All Check Boxes on Page:

javascript:function check(){var c=new Array();c=window.document.getElementsByTagName(‘input’);for(var i=0;i<c.length;i++){if(c[i].type==’checkbox’){c[i].checked=false;}}}check();

Select First 100 Check Boxes on Page

javascript:function check(){var c=new Array();c=window.document.getElementsByTagName(‘input’);for(var i=0;i<100;i++){if(c[i].type==’checkbox’){c[i].checked=true;}}}check();

Just copy and paste it in to your address bar and press return.

I’ve made a few attempts at this before (that have lasted less than a day each!), but for the past week I’ve begun teaching myself Objective-C and working on an App for submission to the App Store.

Objective C isn’t the easiest language to move to, despite what Apple seems to have droves of developers willing to testify – infact, it’s probably the most difficult language to ‘penetrate’ of all the high level languages. That said, the potential benefits and uses of being able to create applications to work on what will likely become one of the most ubiquitous platforms about are enormous.

So, I’ve now gotten to the stage of having a working Application on my iPhone (having payed for the Developer account) with it’s icon etc… It can run a sockets server, and connect to a sockets server. Hurrah.

Over the next 3 weeks (my aim for this app being to a stage where work will be polish and not interesting to write about), I will be posting most days about my progress  and letting you in on how the process of getting an App in to the App Store goes.

Wish me luck!

Since I started using twitter, there’s been a constant up-hill battle of how

to collect the right followers, keeping all your friends as followers, work people, social networks and online communities etc… This should be easier.

Given a group of people all wanting to follow each other, a si

mple submission to a group should be able to keep all of those people’s follows up-to-date based on the other members of the group.

Now that’s possible. Or at least it will be.

TweetGroups allows you to do exactly that – at the moment only for the community of neowin.net at http://www.neotwit.co.uk

The aim is to create a more generalised version that will allow people to create custom groups, manage them etc… but for the moment it is functional.

Okay, this is a bit ‘niche’-ey. I have a US Macbook air with UK Keyboard layout and have spent a few months passively looking for the ‘hash’ key, whilst sort of admitting to myself that I’d probably bought a £1200 machine with no DVD drive, no changeable battery and NO HASH KEY.

But.. about that one, I was wrong… There is a hash key!

Anyone with a US Macbook Air on UK Layout : Ctrl-Alt-3

Finally!

It was an interesting meeting in which the system changed from a spreadsheet to a full implementation of Microsoft Project, but I left with lots of words in my head like ‘tags’ and ‘categories’. It took days for the association to hit me but it all sounds to me rather like the job for a blog.

Each entry could be an update tagged with a project title among other keywords. WordPress could even be slightly modified to store progress of each category along with a few other key pieces of information, but essentially it seems like it could work; you could browse by category for a chronological update of the status of projects. It may even be more advantageous for the developers as they gain the scope of explaining any potential issues to a third party (albeit virtually).

I’m not sure if this has been done before / is implemented anywhere but would be very interested to hear any thoughts on the matter or any experiences.
