How to install the iOS 7 beta on your iPhone 5

Want the latest and greatest iOS that won’t make it into the hands of the masses for a few more months? You’ve come to the right place! First, you must be a member of the iOS developer program ($99/year) to download the beta SDK.

1. First download the iOS 7 beta (make sure you get the right version for your phone depending on if you have ATT or Verizon)

2. Make sure you backup your iPhone files by going to iTunes (just click Backup now)



3. After downloading the ios_7_beta__iphone_5_model_a1428__11a4372q.dmg file, double click on it and extract the .ipsw file to your desktop


4. In iTunes, hold down the option and click on “Restore iPhone…”




5. iTunes will now take care of the rest of the iOS beta installation process! The last thing you should do is click “Restore from this backup” when prompted to keep all your old apps




If you get the error “This device is not registered as part of the iphone developer program”, don’t fret, you just have to go to the iOS provisioning portal and add your UDID.

Best minimalist wallet case combo for iPhone 5

I had the idea to make a phone case that also functioned as a wallet. Turns out this product already exists in the Incipio Stowaway. For only $15-$18 (depending on the color), you can get an elegant phone case that looks just like a normal case, but also has room for 3 credit cards AND a bill. This essentially means you no longer have to carry around a wallet! I highly recommend the Incipio Stowaway.


See a video of how easy it is to use the Stowaway:

Cutest 404 page ever!

I wrote an easy to use API for displaying cute animal pictures on any webpage.The API uses my website, and chooses a random picture from amongst tens of thousands of adorable animal pictures.

To use this free API, just request, and a JSON string will be returned containing the image URL and caption.

This is an example:

{“url”:”http:\/\/\/ElNcPxF.jpg”,”caption”:”My parents got a new dog. We named it Bruce.”}

You can use the following code to parse the JSON and display the resulting HTML:

[code lang=’php]
$jsonString = file_get_contents(“”);
$jsonArray = json_decode($jsonString, true);
$imageUrl = $jsonArray[‘url’];
$caption = $jsonArray[‘caption’];
echo “<br>While we work to fix it, we hope you enjoy this cute animal picture!<br>
Courtesy of <a href=’’></a><br>
<img style=’max-height: 700px; max-width: 700px;’ src=’$imageUrl’><br>$caption”;[/code]

How to get into any college class you want


Class enrollment can be extremely frustrating! If the class fills up before you get a chance to enroll you are stuck refreshing the page every few minutes until someone decides to drop the class. Now there is a better solution that automates the process for you – Instead of having to manually refresh the page until a class opens, Alertification does the painstaking task for you, and sends you a text message or email when the class is finally open! Enrolling in classes just got easier! Alertification works at most colleges in the US, especially at large schools like UCLA, UC Berkeley, UC Irvine, UCSB, and even USC!

Calculate your chances of getting into college

There are countless forums where you can get random people to calculate your chances of getting into certain colleges, but these aren’t accurate at all due to bias and inexperience of the forum members. Not only do you have to wait hours if not days for a response, but you also can’t get estimates at more than a few schools because it’d take too much time for someone to give you a free response.

To solve these problems, I created CalculateMyChances.  Just enter your new SAT score (out of 2400), and you will instantly get reasonably good feedback on your chances of getting into hundreds of different colleges. Included are your odds of getting into all the Ivys – Harvard, Yale, Princeton, Cornell, Dartmouth, and even schools like Stanford, UCLA, and UC Berkeley! Before I made the site there were a few other services that estimated your chances, but I found their implementation either poor or annoying to use. The frustrating ones asked you to sign up for their service, which simply wasn’t worth the effort. The others were created by those lacking even the most basic understanding of statistics and were completely inaccurate. Try out CalculateMyChances and let me know how you like it in the comments!
