MineStream Defender - the ultimate network security deviceLast 12 months I was working on an interesting device that provides the network security features many companies and families are dreaming about. You probably already have heard about different threats out there like internet predators, viruses, spyware, dangerous websites, confidential information leaking from your business and others. Also you probably tried to find answers to questions like

  • Is my office network used appropriately? Do people really use it for work and not something else?
  • Are my kids safe in the Internet? Are their virtual friends really friends?
  • Why is my internet so slow?
  • Who in my network is using the internet most, when and what for?
  • How can I prevent my children or employees from browsing inappropriate content, wasting time in chats or games?

Finally, you might want to get answers to the questions immediately and you don’t want to spend a lot of time configuring every single computer in your network, installing software and other techi stuff … So the answer to all those questions is one small box called MineStream Defender and here is what it can do …

Apr 19, 2008 A typical wireless camera. Let’s take a look inside and get amazed.

Fake LEDs part 1Here is a typical wireless video camera you can find on ebay and also available from many other e-stores. What do you think about it? Pretty cool – for just $30-50 you can buy ability to see all uninvited intruders crawling towards your house in the night darkness.

Apr 17, 2008 Squid: unrecognized httpd_accel_port, httpd_accel_with_proxy on, httpd_accel_uses_host_header

Squid proxyI was recently installing squid at home as a single caching proxy for all computers in my home network. The simple way is just running squid on your linux router as is and configuring every single browser on all computers in your network so they access internet using squid. That’s doable, but boring. The more interesting way is setting up transparent proxy so all your http traffic goes through squid automatically. I’m not going to explain how to setup the transparent proxy as there are tons of articles in the internet about that, for instance:

  • http://www.cyberciti.biz/tips/linux-setup-transparent-proxy-squid-howto.html
  • http://tldp.org/HOWTO/TransparentProxy.html
  • http://www.deckle.co.za/squid-users-guide/Transparent_Caching/Proxy

The documentation is very straightforward, and has just one problem: it is outdated and doesn’t work with the most recent versions of squid. I’ve read several instructions and was always ending up with these error messages:


2008/03/23 01:51:52| parseConfigFile: line 26 unrecognized: 'httpd_accel_port 80'
2008/03/23 01:51:52| parseConfigFile: line 27 unrecognized: 'httpd_accel_with_proxy on'
2008/03/23 01:51:52| parseConfigFile: line 28 unrecognized: 'httpd_accel_uses_host_header on'

Here’s how to fix the problem …

Apr 6, 2008 1000th viewer of routerbot video (routerbot is a domestic router turned into a robot)

Routerbot - a router (Linksys WRT54GL) turned into a sophisticated robot.I just noticed that my video about domestic router turned into robot got its 1000th viewer. This is my very first youtube video and I’m very proud of that.

If you’re thinking about what to do this weekend, building a robot for your kids could be a good idea. This is not very difficult and the result is really amazzzzing. You will get a robot that can be teleoperated via WiFi (i.e. you can control it from almost anywhere in the world) or programmed using shell script for the price way less then an average robot you can get in a hobby store.

I’m getting really nice emails with congratulations on selling pizza.com. From time to time I’m also finding posts and articles about how lucky I am. Thank you very much!! The only problem with that is

I’M NOT THE OWNER OF PIZZA.COM DOMAIN!

Never was and most probably never will be. I’m the one who made the http://www.pizza.com website (design, programming, system support etc) as a hobby project, but this is it.

Anyway, thanks to everyone – I’m forwarding your really nice emails with congratulations on selling pizza.com and posts and articles about how lucky I am to the real (former) owner of the domain. I’m sure he is glad to get them – he is a really nice guy.
