I've have been in trouble this couple years ago, some bad guys I encounter at the street I'm afraid to fight of because I do not know martial arts or any technique to beat the attacker, so all I do is run away making my self safe from them. Sometimes fighting is not the way to defend your self, if you think there's a way you can run then go do not take the risk just to beat your enemy remember running away is the best technique in martial arts to make your self safe.

Today, lots of gadgets are invented for those who do not know martial arts as well as for those who do not have time to practice some technique. A very effective gadgets I always put on my back pack is Taser or Pepper spray. But taser is kind of expensive so pepper spray is an option if you can't afford taser, both are effective for defending to an attacker. You can browse more non-lethal weapons at www.worldclassselfdefense.com and for surveillance system you can visit www.worldclasssurveillance.com I just purchase another pepper spray last week because my uncle want me to teach him how to use pepper spray and the Do's and Don'ts  of it.

Always remember that fighting is not the solution to defend your self although its choice if there's no way out. Use your mind not your emotions, think positive, control your emotions that's the key points when you are in trouble.

Operating system?


Most of us wonder what type of operating system use in making some freaky stuff in movies like hacking and cracking government systems and different servers. The question is what operating system? the answer could be Linux, Windows, Mac and Unix. These operating system can be use in making different animations like overriding power grid, Satellite etc. But as you can see, they do not show the logo of any of these however in other movies they show only desktop wallpaper of windows even mac but not linux. If you're gonna use windows OS on your movie your gonna pay it as well as Mac because these are commercial operating system. Software presentation in movie used Linux family why? because linux is free and open source anyone can use it and distribute it but you need the GPL (General Public License) before distributing any application coded use from linux infrastructure.
