Ever wanted to move that pesky cursor on an iPhone (without Touch 3D), for example in your browsers address bar? Apparently you can press and hold the space bar on the on screen keyboard. Or, as Apple puts it:
Turn your keyboard into a trackpad
- Touch and hold the Space bar with one finger until the keyboard turns light gray.
- Move the insertion point by dragging around the keyboard.

Prevent email-spoofing, phishing and spam by setting these DNS TXT Records.
Send Policy Framework (SPF):
domain.com. IN TXT "v=spf1 a mx include:domain.com ~all"
DomainKeys Identified Mail (DKIM):
Generate public/private key with opendkim-tools.
$ opendkim-genkey --bits=2048 --domain=domain.com --verbose
Use the private key for your mailserver, eg postfix.
Use public key for the TXT record (“1234+ABc/dEF"):
_domainkey.domain.com. IN TXT "o=-" default._domainkey.domain.com. IN TXT "v=DKIM1; g=*; k=rsa; p=1234+ABc/dEF;"
Domain-based Message Authentication, Reporting and Conformance (DMARC):
_dmarc.domain.com IN TXT "v=DMARC1; p=reject; rua=mailto:[email protected]; ruf=mailto:[email protected]"
