The LOAD and uptime , top commands .

Today I will speak about LOAD , uptime , top under your cores..

Let’s get info on each processor in your system

You can get LOAD about your cores using some linux commands.

… using top command

or uptime command:

Load averages are the three numbers shown you the LOAD averages over periods of time: one, five, and fifteen minute averages.

If you want to produce or to put load on LOAD on core or on more cores , then use this

… or to make more LOAD

This will show you how it’s working your cores.

If the LOAD is between 0.00 and 1.00 means there’s no traffic on the bridge at all.

The LOAD can be 1.00 means the bridge is exactly at capacity of core.

On multi-processor system, the load is relative to the number of processor cores available.

This means the load can be more then 1.00 and will working fine.

For example It’s still healthy with a load of 3.00 if you have a quad-processor system.

If you have also one core and the load is 1.70 this means the core is full (1.00) and 0.70 will wait the capacity of core to be released.

Working with android emulator – part 001.

Today I will show you how to deal with android emulator.

I use in this tutorial the android from Pygame Subset for Android.

You can use any android SDK and also you can read my tutorial about Pygame Subset for Android.

First you need to install mesa development libs.

The next step is to create one avd.

We can see all avd with :

If you got this error …

…you need to export LD_LIBRARY_PATH and then you can start emulator

You can use -no-audio arg to make emulator faster.

… or just use this:

Tne next command will install your aplucation on emulator. Open another terminal and use this:

And now you can tets your application…

Use Fingerprints to check web server’s secure connection certificate.

To make sure that you are connected to the right secure website you can use Fingerprints website.

You compare the fingerprint of its certificate in your browser against a trusted source that provides you with fingerprint records.

Looking up fingerprint certificates because each web browser handles this in a different way.

Now compare the fingerprint displayed in the web browser to the certificate pulled by the script on the GRC website.

Also some companies can use multiple certificates that’s mean that the certificate differs even if you are connected to the real website or server.
