Watch Your Home TV Set On Your iPhone From Any Wireless Network Connection

Many people may not be aware of a company called Sling Media that makes devices that connect to your DirecTV, cable, or other satellite providers receiver so you can watch your own television from any Internet connection. The product that makes this possible is Sling Box and it connects in between the output of your cable or satellite receivers output and your televisions input. Then it connects to the network at your house via a switch, wireless router, or the like and provides instructions on how to view remotely from any computer and many mobile devices. There is an application available from the iTunes store that will allow you to connect to the Sling Box at your home via your iPhone so you can watch your home television from your iPhone. This includes watching shows that have been recorded on your DVR, etc.

iPhone Digital Camera Driver Issue, iPhone Not Showing Up Under My Computer

I typically transfer images from my iPhone to my Windows XP computer by clicking on My Computer, clicking on the Apple iPhone icon, and then transferring the images to another folder on the computer. Today I plugged in the iPhone via USB to my Windows XP laptop and I was surprised to see that the iPhone Camera was not showing as a drive after clicking on My Computer. To verify I hadn’t made a configuration change on accident that was causing this to not show up I verified that the computer was not seeing the iPhone’s camera by opening up Control Panel and clicking on Scanners and Cameras.

**UPDATE: The first solution is what worked for me but there have been some comments confirming that the below will not solve everyones issue. Another solution to try is to delete any images you have saved to the Camera Roll from email. It appears in some situations if images are saved from emails that it is causing issues with the digital camera driver and you will be unable to retrieve images from the iPhone if you have saved images you received via email. I attempted to duplicate the issue with emailed gif’s and emailed jpg’s but I was unable to though I am sure this issue exists for others as it has already been confirmed at least twice in the comments below.

How Much Do Internationl Text Messages Cost From iPhone On ATT Wireless

I have been doing some business with people overseas and sometimes we communicate via text message so I needed to verify how much it cost to send text messages from my iPhone on ATT Wireless’s network to cell phones overseas. In my specific case I wanted to verify sending text messages from the United States to London, England or the United Kigdom. After looking around a bit I found that only certain countries are supported and it costs $0.25 per text message. Below I have listed some more resources and information on picture messaging.

Shell Script To Configure A Read Only User On A PostgreSQL Database

**UPDATE: New article here.

Its a little more complicated to create a read only database user with PostgreSQL than say using something like MySQL. You will need to grant select access on each table in the database for the read only user. Keep in mind that each time you add a new table you will need to either run the shell script below again or manually grant select access on the new table for the read only user.

Cisco IOS: Forward Called Teclo DID To An Extension, Translate, Translation-Rule Limitation

A client of mine had a Cisco 2811 installed before I started working for them so I had to go over the configuration to become familiar with things. One of the Cisco IOS configuration items used was translation-rule which will allow 10 to 15 Rules to be created under each translation-rule. In this scenario they were using translation-rule to forward external DID’s from their telco provider to internal extensions. This works fine except for the fact that if you have more than 10 (in this case) external numbers you won’t be able to continue to forward them to internal extensions without complicating the configuration using multiple dial plans, etc. The easiest way to get away from the translation-rule being used in this way is to assign t he external DID telephone numbers as secondary numbers under each extension configuration as explained below.
