Since I was busy with my new blog I missed writing about it: Nmap 7 Released on 19th of November.

Of course they did a good job, and improved performance, implemented fully IPV6-support and better ssl-scanning(using scripts), but the really surprise for me was that they also developed a better Netcat:

Using the program “at” one can start any job on Linux at any specific point of time. The command “batch” is shipped with “at” and executes commands when the load average drops below 1.5.

I upgraded the blog software. It was a major upgrade and many things are different in this version. So I took the chance to also improve my design. It’s more clear and fully responsive now.

If you have any harddisk, you can boost it’s performance using a ssd-cache. The linux-kernel ships a function called bcache. Checkout the kernel-documentation for it.

Today is the first anniversary of this blog. I created this blog for documentation, sharing my knowlege and improving my english(the latter did not work out well). It turned out that I like blogging and I am very happy about it.
