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.

Too bad the accepted answer forgets about deleted files.
Use one of these to compare (but not sync) two directory trees.
For size-only comparision:
rsync -n -avr --size-only --delete /abc/home/sample1/ server2:/abc/home/sample2/
If you want to compare both contents and size:
rsync -n -avrc --delete /abc/home/sample1/ server2:/abc/home/sample2/

via: diff – compare files in two directory on remote server using unix – Stack Overflow.

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).
Because of the naming, turning on CEC can be confusing: How to Enable HDMI-CEC on Your TV, and Why You Should

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).

Interesting:
During the last weeks I finally got my hands dirty with IPv6. A comment on my blog and an email informed me that my server (hosting this blog) is not reachable via IPv6, albeit it has an IPv6 address. That said, I tried to get that running and fell into several holes, due to firewalls, […]

Hopefully someone will move this to Github before Google code goes down: paping – Cross-platform TCP port testing, emulating the functionality of ping (port ping) – Google Project Hosting.
Paping (pronounced pah ping) is a computer network administration utility used to test the reachability of a host on an Internet Protocol (TCP/IP) network and to measure the time it takes to connect to a specified port

Apache configuration can be tough, so here are some links related to RewriteRule.
One day I hope to write a more in depth article around some of them (:
