| Tutorial quote: Some of you may know the commercial Flexnet Licencing Application (İMacrovision). It's a client-server based solution for managing the usage of socalled Flexnet-enabled applications. You can hold licenses of more than one product on one license-server. As you typically have to buy licenses and licenses can be expensive it would be nice to have a monitoring solution to see the utilization of the precious licenses, whether they are underutilized (so money is wasted) or are always fully utilized (so that you can suspect that sometimes people cannot do their work, or only delayed) which is also a waste of resources. As far as I know there are commercial applications for performing such reports, but again you have to spend money. Why not build a simple system yourself, which shows the actual and past usage in an "MRTG style"? |

Tutorial quote: In case you want to delete some confidential data from your computer just to make sure that it is no longer accessible to anyone, then do not delete the file using the regular rm command because there will still remain a chance that someone might use a software to recover your deleted data before the specific storage area is overwritten by new data. The proper way to permanently dispose of such data in Linux is the shred command.
