Flowing Fix: Generating QRcodes

Quick Response Codes (QR codes) are a type of two-dimensional barcode (or matrix barcode) which allows for encoding of information that can be read rapidly. For more about QR codes see https://en.wikipedia.org/wiki/QR_code

LaTeX can generate QR codes: 

To enable this capability in LaTeX, include the qrcode package (https://ctan.org/pkg/qrcode?lang=en) A tutorial with simple example code (see Example 11) can be seen at https://www.hydro-perturbations.com/help-files/latex-quick-examples

Flowing Fix: How to easily determine the LaTeX code for a symbol

Every have trouble remember the code to a LaTeX symbol?

Typically when you want to find an infrequently used symbol in LaTeX you often have to refer to the comprehensive symbols list: http://ctan.math.utah.edu/ctan/tex-archive/info/symbols/comprehensive/symbols-letter.pdf. However, this can be time consuming and difficult to find the symbol you need.

Detexify can help find the code to LaTeX symbols simply by drawing what they look like.  Try it out for yourself, and you will shortly have a new bookmark for Detexify in your browser.

For wireless internet access on Campus:

Email Options 
Below are various options for email, for university mail Nils suggests using the University Exchange option (UIUC option 1 listed below) since the university is eventually going that way

For Google (here are two recommended options):
Google Option 1): If you want Google Gmail, Google Contacts and Google Calender (using Google's exchange server) on the iPhone here are instructions:

Google Option 2): If you want to use Google IMAP

For University (two options):
UIUC option 1): (Recommended by Nils) If you get a University Exchange account (information about the exchange account: http://www.cites.illinois.edu/exchange/) information regarding the iPhone : http://www.cites.illinois.edu/exchange/iphone.html

UIUC option 2): Another method which doesn't use Exchange (but i do not think the reading of emails will be synced from computer to phone and vice versa)

-------------------------
Note: Apple now allows multiple exchange accounts on the iPhone

A few recommended iPhone Applications:
Also, as I had mentioned here are some applications for the iphone.  You can either install them using the App Store icon on the iPhone or through iTunes installed on a computer (then syncing the phone). Either way you will need to create a itunes store account, but each of the two methods allow you to create an account if you don't have one.  (The App Store icon on the iPhone might be the easier way if you don't have itunes installed, but there are size limitation on apps u can download (i think 10mb limit) and it is slower than directly syncing with a computer,  if you want faster speed or need to install an app larger than 10mb you need to sync to the iTunes on the computer.)  Also, syncing you phone to the computer using itunes, automatically makes a backup of your phone, for that extra piece of mind.
Here is the list of some nice FREE Apps:
(if you use the App Store on the phone, you will have to search for the title of each application, if you have itunes installed on a computer you can click the hyperlinks below for each application)

Aroundme :  helps find various information (businesses, restaurants, etc.) that are around your location.
http://itunes.apple.com/us/app/aroundme/id290051590?mt=8

Appbox Lite: has a couple of useful applications wrapped into one application, (including a digital level, unit converter, currency converter, and others)
http://itunes.apple.com/us/app/appbox-lite/id307094023?mt=8

Units:  it is nice unit converter application
http://itunes.apple.com/us/app/units/id284574017?mt=8

Skype: just link the Skype for the computer
http://itunes.apple.com/us/app/skype/id304878510?mt=8

Google Earth: just link google earth for the computer (best to use this with wifi turned on, though 3G is ok)
http://itunes.apple.com/us/app/google-earth/id293622097?mt=8

GorillaCam: enable your camera to have time lapse, timer, and some other features
http://itunes.apple.com/us/app/gorillacam/id342972390?mt=8

 DropBox:  first I would click this link to see a short video which explains it https://www.dropbox.com/
 Think of this program as a wireless USB key which you can view and send files in a certain folder on your computer from the iPhone.  (In order to use this need to create an online account and install an application on your computer to get the full benefit) here is the itunes link http://itunes.apple.com/us/app/dropbox/id327630330?mt=8
