Internet of Things (IoT) and Ransomware

Unfortunately, and no matter how funny the cartoon may be, this may be what the future is going to bring us if we're not careful.

Below are some of the online appliances (just random picks from Google):

The only item I couldn't find was the Internet-connected broom. But I guess that won't take long. The other items can all be bought with some sort of Internet connectivity, and are therefore potential vulnerable for abuse.

VPN and Resolving Issues on OS X

We have a lab which we can access by using a VPN (Cisco ASA and Cisco AnyConnect). This setup has a so-called split DNS configuration, which means that only resources in the lab are accessed through the VPN tunnel. Regular Internet traffic uses my local DSL connection.

At my house I (like most folks) rely on DHCP for providing me with IP address, gateway and DNS servers. My local subnet uses for DNS and is my default gateway. So my clients are in the same subnet as my DNS server (directly-connected).

All these things considered I should be able to browse the Internet while I have a VPN running. Well, that's where you're wrong.

Photo Contests, JPEG, and DPI

This post is about something that bothers me a lot. Especially, because it originates from a place where you think they should know better. It's about Dots-Per-Inch (DPI) and JPEG (the popular digital image/photo format).

It all starts, when I read the requirements of certain online photo contests. The criteria for entering the contest contain the following: The photo entering the contest must be in JPEG with maximum quality (least compression), AND 300 DPI.
