Codetown ::: a software developer's community
Simple. If you have a commercial good or service that you'd like to advertise with us, the rate is $95 for 3 months for each ad. This includes jobs, blog posts, events, discussions and anything for which you charge a fee.
Just PayPal the payment to ads@codetown.us and post your ad. You can also mail a check to Cambridge Web Design, PO Box 1741, Winter Park, FL 32790-1741. We accept credit cards, too. Just send Michael Levin a message (mike@codetown.us) with your phone number and we'll chat on the phone.
Please invite some new members, if you please, and feel free to share Codetown's content on other social networks. We have pretty good volume at this point, depending on SEO. It seriously helps when you share and invite people...
If you are looking to post a job description head over to the Groups page. There you will find the Jobs group, where you can post your job as a discussion with a detailed description and salary, rate, or range. We ask you to disclose the compensation as a favor to the developers.
Other places you can advertise include the Events section. We can add a link to your site in the Reading List for the homepage of the Codetown website or one that will show up in the Reading Lists for specific groups.
Codetown content gets marketed, promoted and otherwise passed along by yours truly (in a way I hope is pleasant) to like-minded individuals more or less, depending on the content.
Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

Most cloud systems make one authorization decision at login. Everything after runs on trust established at authentication time. For systems handling regulated data, that gap is where breaches happen. This article presents a continuous authorization architecture covering risk-tiered evaluation, behavioral baselines, privacy-preserving audit trails, and a phased and incremental rollout.
