Pixenate is an online photo editor. It has a bunch of features as you can see below. Simply upload your photo, edit it, and either save to disk or upload to Flickr. No need to register, just upload an run!
During the week I work as a Network/Systems Administrator. There are plenty of online tools that I use daily to make my life easier. One of them is dnsstuff.com which lets you check everything you need about an IP-address or domainname. Iptools.com and domaintools.com are two other alternatives. For those of you who are into network administration and need to calculate those subnets and networks – check out a Subnet Calcluator.
