AppsAmuck Great IPhone Dev Tutorial Resource For Beginner IPhone App Developers

I’ve been following the AppsAmuck 1-app-a-day tutorial – it’s been an invaluable resource for someone like me who came into the IPhone App Development area with zero Objective-C or Mac OS programming experience.
Apps Amuck starts on day 1 with an iPhone app tutorial that is based on the example/tutorials provided by Apple. Each day the apps/tutorials get more complex, and full source code as well as a final verion of the IPhone App is included in each tutorial. They are currently giving away one app per day for the next 31 days.
The tutorials they provide are small, one trick ponies that allow you to perform tasks like finding your location, building a fire, figuring out your IP address, and more. The site allows you to see a screenshot of the application, read a description, and download the source code to play around with. If you have a developer provisioning file (meaning you’ve been accepted into the developer program), you can even sync the applications over to your iPhone or iPod touch.

Top 10 PHP Mistakes Beginning Developers Make
Posted by Blerz on
February 5, 2009
From the NetTuts site, comes a list of the top 10 common PHP errors that beginning developers make. I’ve found myself making these many times, though as time goes on, finding and fixing these errors becomes more of a second nature. I do keep a checklist (I will post it soon) of PHP security and usability issues that I go through before I release code into the wild. Read the article, and pay close attention to the security issues mentioned – these are the errors that will get you turned off by your shared hosting, or cause your website or web application to become unusable or broken.
Some highlights from the original NetTuts article:
7. Not Protecting Your Session IDs:
A very common PHP security mistake is not protecting session ID’s with at least some sort of encryption. Not protecting these Session ID’s is almost as bad as giving away a user’s passwords. A hacker could swoop in and steal a session ID, potentially giving him sensitive information. MT Soft an example of how to protect Session ID’s with sha1:
view plaincopy to clipboardprint?1. if ($_SESSION['sha1password'] == sha1($userpass)) { // do sensitive things here
2.
3. }if ($_SESSION['sha1password'] == sha1($userpass)) { // do sensitive things here
}
Adding the shai1 to the ($userpass) gives an added bit of security to the session. Sha1 isn’t a bulletproof method, but it’s a nice barrier of security to keep malicious users at bay.
