There's a new batch of pictures

There's a new batch of pictures. This batch is with my uncle Sabi and with my cousin Selim. Of course, the kids play a key role in the pictures :-)

Negative Security and Positive Security

I find myself a lot lately explaining the difference between positive security and negative security.

Positive Security: a security policy based on modeling of the application or the system that is being defended. Things that agree with the model are considered legal while all other things are suspicious to be illegal.

Negative Security: a security policy based on modeling of the malicious things (e.g., attacks, worms, viruses, and so on). So that things that agree with the model are considered suspicious to be illegal while all other things are considered as legal.

Warming liquids for babies in a microwave oven

I saw a discussion in a Tapuz forum about heating baby liquid food in a microwave oven.

One person claimed that this is forbidden, and I got curious and started asking questions.
