I wanted to let my readers know that I migrated from my previous hosting to a new one. There was nothing wrong with the previous one, but I wanted to go out shopping for something cheaper and still as reliable.

Lots of friends gave me good recommendations for Linode and the price was tempting so I thought : “Why not ?”.  The most noticeable advantage, apart from the price reduction, was the speed improvement, as I got myself a more powerful VPS and then now I have more room for new experiments.

Later I also noticed some little but very welcome improvements. These are just minor details, but together they account for a great experience. So, I’m here to let you guys now that if you want a good, reliable, speedy, and still cheap hosting provider for your VPS, just give Linode a try.

I’m sure you won’t be disappointed.

Here’s a really quick way to find out if your “ps” binary has been compromised :

# ls -d /proc/* | grep [0-9] | wc -l ; ps aux | wc -l

The commands above are going to show you two numbers : the first one is the number of running processes according to your kernel and the second one is the number of running processes according to you “ps” binary.

If the second one differs from the previous one, something is wrong and this could mean your “ps” binary was compromised. If this happens to you, maybe your system is not a trusted system anymore.
