I bumped into a disk full issue again because of the btrfs/snapper combination in openSuSE and df basically lying about the disk space, so I w rote this Nice diskinfo alias showing du, df, btrfs, parted, lsblk.
You can combine this with A bash script to btrfs snapshot details like disk sizes (requires btrfs quota to be enabled) to find out which snapper snapshots take up a truckload of space and might be safely removed.

But there is also etckeeper. There is even a set of manual installation steps for opensuse: backup – etckeeper for opensuse – bash script install and configure – Unix & Linux Stack Exchange.
Three important etckeeper gotchas with powerful scripts like pre-commit /etc/etckeeper/pre-commit.d:

Since ESXi is based on busybox, it is using ash a variation of sh (the classic bourne shell) called Almquist shell and most nxes use some form of bash a lot of things won’t work.
For instance, doesn’t support sh –version.
Luckily there are uname -mrs and (more elaborate) vmware -vl to get the version.
Note there is support busybox aliases so alias dir=”ls -laF” works, and you can define aliases for the version information too.

Last friday I updated the examples at *nix networking – lsof: How to tell what process has a specific port open on Linux (via: Server Fault) as I needed to document some of the machines around here (so it becomes easier replacing them).
I also added some links to background information and (when I get to using it: OS X still goes without) a good iproute2 starter page.

If for instance your Boxee gets old or breaks down, you can use a Raspberry Pi as a replacement with Kodi as media player.
This combination will understand the Video+USB over HDMI which most TV supports officially named HDMI-CEC , but most vendors “invented” their own names (see list below).
The core is the kodi support for CEC.
Basically it comes down to using three cables going to the Pi: Power from TV (or some other source), HDMI to TV, and wired Ethernet. And a distribution for RaspberryPi containing kodi will work, for instance from OpenELEC Mediacenter – Download: Raspberry Pi Builds
Chad MILLER has more details on how to get this to work: My Boxee box is getting old, but I knew of no replacements. The problem is I …
Names known for HDMI-CEC via Wikipedia:
Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), E-link (AOC), Kuro Link (Pioneer), INlink (Insignia), CE-Link and Regza Link (Toshiba), RIHD (Remote Interactive over HDMI) (Onkyo), RuncoLink (Runco International), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).

Even after the SpeedTouch password algorithms were disclosed 2008, ISPs keep using weak algorithms to generate their default WPA/WPA2 passwords in their routers:
A short while ago, blasty published code to generate the WPA2 passwords for UPC routers. Even though Ziggo now owns UPC, a lot of this UPC equipment is still in use. I guess it won’t be for long that similar code for Ziggo routers will be published too.
The code at https://haxx.in/upc_keys.c is easy to download, build and run on a Mac OS X machine even when you don’t have Xcode installed (use the “xcode-select –install” trick):
wget https://haxx.in/upc_keys.c gcc -O2 -o upc_keys upc_keys.c -lcrypto ./upc_keys UPC0053284 5 ./upc_keys UPC0053284 24

Many sites giving your public IP address return a web page with a bloat of html. From the command-line, you are usually only interested in the IP-address itself. Few services return exactly that.
Below are command-line examples to provide the public IP address mostly from a *nix perspective. Usually you can get similar commands to work with Windows binaries for wget and Windows binaries for curl.
In the end, I’ve opted for commands in this format, as I think akamai will last longer than the other sites (but does not include an end-of-line in the http result hence the echo on Mac/*nix):
I’ve not tried aria2 yet, but might provide commands for that in the future.
These are the Linux permutations for akamai:
curl whatismyip.akamai.com && echo curl ipv4.whatismyip.akamai.com && echo curl ipv6.whatismyip.akamai.com && echo curl ipv4.whatismyip.akamai.com && echo && curl ipv6.whatismyip.akamai.com && echoThe last two are convenient when you have both IPv4 and IPv6 configured on “the outside”.
You can replace curl with wget -q -O – (which outputs to stdout) for each command. You can even ommit the http:// (as that is the default protocol for both curl and wget).
