Sorry, IT: These 5 Technologies Belong To Users: GMGruman writes "The BYOD (bring your own device) phenomenon hasn't been easy on IT, which has seen its control slip. But for these five technologies — mobile devices, cloud computing services, social technology, exploratory analytics, and specialty apps — it has already slipped, and Forrester and others argue IT needs to let go of them. That also means not investing time and money in all the management apps that vendors are happy to sell to IT shops afraid of BYOD — as this post shows, many just won't deliver what IT hopes."

I have a system with a 5 minute time delay. It's domain joined but for unknown reasons it has a 5 minute delay. Now being an e-commerce system this is a bad deal. Credit Card companies don't like it when transactions are delayed by 5 minutes (can you say "man-in-the-middle"?).
Now I just need to figure out why it was off in the first place.
Here is the command to reset the time to the Doman time.
C:\Documents and Settings\wal>net time /?
The syntax of this command is:
[\\computername | /DOMAIN[:domainname] | /RTSDOMAIN[:domainname]] [/SET]
[\\computername] /SETSNTP[:ntp server list]
C:\Documents and Settings\wal>net time /domain:your.domain.com /set
Current time at \\server.your.domain.com is 12/20/2011 9:56 AM
The current local clock is 12/20/2011 9:51 AM
Do you want to set the local computer's time to match the
time at \\server.your.domain.com? (Y/N) [Y]: y
The command completed successfully.
C:\Documents and Settings\wal>

We have all been doing email address validation for a very long time to make sure that the email is correctly formatted. This is to avoid users entering wrongly formatted email address but still they can accidentally give us a wrong email address.
Example of a correctly formatted email address but still wrong:
firstname.lastname@example.org [VALID email format but it does not exist]
Above case specifically happens when you take important customer email on phone and you type in the wrong email. So is there a QUICK solution to really check the email without sending a test message to the user? Yes.
A quick & simple check below can be implemented in most programming language including PHP, Python etc. It relies on using the same SMTP which is used to send emails.
To check if user entered email email@example.com really exists go through the following in command prompt.
First - Find mail exchanger of reddit.com
nslookup – q=mx reddit.com
reddit.com MX preference = 10, mail exchanger = mail.reddit.com
mail.reddit.com internet address = 184.108.40.206
Second - Connect to mail server mail.reddit.com
telnet mail.reddit.com 25
220 mail.reddit.com ESMTP Postfix NO UCE NO UEMA C=US L=CA Unsolicated electronic mail advertisements strictly prohibited, subject to fine under CA law CBPC 17538.45. This electronic mail service provider’s equipment is located in the State of California. See http://www.reddit.com/static/inbound-email-policy.html for more information.
mail from: <firstname.lastname@example.org>
250 2.1.0 Ok
rcpt to: <email@example.com>
550 5.1.1 <firstname.lastname@example.org>: Recipient address rejected: User unknown in local recipient table
221 2.0.0 Bye
1) the 550 response indicates that the email address is not valid and you have caught a valid but wrong email address. This code can be on the server and called on AJAX when user tabs out of the email field. The entire check will take less than 2 seconds to run and you can make sure that the email is correct.
2) If email was present the server will respond with a 250 instead of 550
3) There are certain servers with a CATCH ALL email and this means all email address are accepted as valid on their servers (RARE but some servers do have this setting).
4) Please do not use this method to continuously to check for availability of gmail / yahoo / msn accounts etc as this may cause your IP to be added to a blacklist.

After you convert the song/sound to the AAC version (m4a), make sure to delete the AAC version of the song/sound in iTunes (while keeping the file). Then, after you rename the file to the Ringtone (m4r) version, you can import that file back into iTunes. Otherwise it won't show up in the "Tones" section and be 'syncable' to your device.
