Office hours are a great place to chat with other developers and help or get help with any questions that come up.

Everyone is always welcomed regardless of skill or experience. If you are curious come on out.

Curious about Clojure? Have questions about Emacs or Cursive or Vim or Spacemacs or anything else? Come on out and we'll help.

This meeting will be a little different. There will be no microphones or projectors but everyone is encouraged to talk about a project they find interesting or show something they're building. Participation is totally optional but we hope to hear about any side projects you're working on, because a lot of times the most interesting things we build are built when we're supposed to be doing something else!

Presentations are intended to be brief 5-10 minute talks.

Agenda:

• How to build a mashup using data on recreation.gov (http://recreation.gov/)

• How to learn business acumen by freelancing software dev skills

If you've got something you'd like to talk about, send us a direct message so we can add it to the agenda.

Insecure deserialization is one of the most critical web application security risks, yet it is by no means a new vulnerability category. Data serialization and deserialization have been used widely in applications, services and frameworks, with many programming languages supporting them natively. Deserialization got more attention recently as a potential vehicle to conduct several types of attacks: data tampering, authentication bypass, privilege escalation, various injections and, finally, remote code execution. Two recent vulnerabilities in Apache Commons and Apache Struts, both allowing remote code execution, helped raise awareness of this risk.

We will discuss how data serialization and deserialization are used in software, the dangers of deserializing untrusted input, and how to avoid insecure deserialization vulnerabilities.

The AWS SDK for Java version 2.0 is a complete re-implementation of the SDK for the Java language. It provides a modern API that leverages the latest capabilities from the Java platform. This presentation will highlight key differences between the V1 API and the V2 API. Also, we will examine the V2 HTTP layer and the updated API for AWS CloudMetrics.
