How To : Install Nagios Core 4 on Ubuntu Linux

Nagios is one of the most popular Open Source application being used for the purpose of IT Infrastructure and Network Monitoring. Basically, this tool is available in two editions, namely, Nagios Core edition which is Open Source and absolutely free to download and Nagios XI edition that has to be purchased by the user. Of course, Nagios XI will have additional features as compared to Nagios Core, but when configured with additional open source plugins and softwares, Nagios Core can provide you with similar or exact results as those in Nagios XI.

Different Quality Backup Idea

My idea is simple. For media that depends on lossy compression it should be possible to ”patch” the media file with a smaller file of same resolution but a lower quality. The backup file is smaller due to more lossy compression. For this to work on image files the format probably need to loose some dependency on the previous block. One error should not affect the rest of the image. On the blocks you then perform some checks. The idea is then that if you encounter a error in the original big image file then you can patch it with the block of pixels in the smaller backup file. The block in the backup file would be of lower quality but look similar. You probable would not notice that the image has been fixed.

 

For a .jpg photo of 3.3MB I saw that I would only need a 350k version. To keep it simple one could store both versions in the same file as an option. For those who don't make backups I think this would make it easier to recover otherwise lost photos.

 

I hope you found this idea interesting.

 

Tips for Cloud Computing Security

    Shared software, shared resources are integral elements of Cloud Computing, which has become a rage today. It’s being used by companies looking for flexibility and scalability. But there are risks involved that you have to keep in mind while using public, private or hybrid cloud computing options. Security of your vital data is of great importance to you and it should be protected while you get the best benefits of cloud computing services. To make effective use of cloud computing and to ensure that data is transferred online securely, there are certain tips you must follow.
 

Know how your data is protected

    Data encryption and firewall security is crucial and you have to know more about these aspects when you sign up with a service provider. Public cloud SaaS solutions make secure encryption practically mandatory. Cloud computing resources should also have an inbound firewall for security reasons. You might be on a cloud but you still have to have strategies in place in case there is an external attack or hostile activity on the system. Service providers that talk about their security measures openly should be given precedence because it enables you to have your own strategies in order.

Broadcast Quality For Online Video Interviews

 

A simple idea to get independent high quality video for online interviews would be to cheat a little. This would only work if your not required to publish the video in real time.

 

The idea is to use dual recordings with the devices. For example. If the person to be interviewed has a high quality web cam but poor internet connection. The software could store a high quality video recording of his part of the session. In real-time the interview would be of the quality the connection can handle but because the stored part can be re-transmitted after the interview is done. It can then with the other videos restore the quality.

 

Low Resolution Preview Idea for Open Source Video Editing

 

An idea to speed up the process and use less resources when editing HD video would be to use a low resolution version of the video as a guide. Akin to 3D software, this would be like rendering the animation first at a low resolution.

So with this you first create a low resolution version of the video. Do all the cuts and effects. Then you preview the result. If the result is good you render the video with the high resolution. With the actions as a script.
