I didn’t know sweetcode until I found it referenced on the tickle homepage:

Sweetcode reports innovative free software. “Innovative” means that the software reported here isn’t just a clone of something else or a minor add-on to something else or a port of something else or yet another implementation of a widely recognized concept.[about sweetcode]

Everything over there is interesting stuff. And sweetcode itself comes fully RSSified.

You are in in Rene’s room. (/home/rene)

This is the home of the lesser gurus and the neophytes. You see pasty people sleeping. Some have a keyboard pattern imprinted on one side of their faces. These people need to get out more.

You are carrying Gandalf’s magic staff, a backpack, a crystal ring, a diamond, a longbow, and a staff.
Edrion the illusionist whispers: “It is rumored that every man who enters this place, becomes infected with disease within a few days time!” He nods enthusiastically

This is the new adventure shell which makes system administration an adventure. [via Gedankenfetzen]

After the make installkernel; reboot step you have to make sure that you actually boot the new kernel, not the old one. without manual intervention the new kernel is searched in the old location leaving you with the 4.x kernel loaded. To get the new one type at the boot prompt:


unload
load /boot/kernel/kernel
boot -s


then carry on with mount -a; cd /usr/src/; make installworld.

I always thought the interactive Python prompt would be an ideal enviroment to experiment with unusual IP packets. Seems I’m not the only one. Philippe Biond created the wonderful package scapy which

is a powerful interactive packet manipulation tool, packet generator, network scanner, network discovery, packet sniffer, etc. It can for the moment replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, ….

Scapy uses the python interpreter as a command board. That means that you can use directly python language (assign variables, use loops, define functions, etc.) If you give a file as parameter when you run scapy, your session (variables, functions, intances, …) will be saved when you leave the interpretor, and restored the next time you launch scapy.

Philippe als has a wealth of other interesting Python scripts on his page.

I came across an article called “Prioritizing empty TCP ACKs with pf and ALTQ” with shows impressively how much throughput you can gain on your ADSL line by cleverly playing with the queuing. The author did that on OpenBSD which vomes with an integration between ALTQ and their Packet Filter pf.

Since ALTQ still isn’t shipped with FreeBSD I wonder if I can get the same behaviour using ipfw2 and dummynet.

Seems the day has come for my Netgear DSL Router to be replaced by a FreeBSD Box.

I have been interested in Zoë. Now that it comes with plugins for MacOS X Mail I think I will give it a serious try.

It is hard to describe, what Zoë is:

The goal here is to do for email (starting with your personal mailbox) what Google did for the web… The Google principle: It doesn’t matter where information is because I can get to it with a keystroke.
So what is Zoë? Think about it as a sort of librarian, tirelessly, continuously, processing, slicing, indexing, organizing, your messages. The end result is this intertwingled web of information. Messages put in context. Your very own knowledge base accessible at your fingertip.[19. Aggregator]

ID does so by integrating Mail Protocols, The Web and RSS.

What an übercool hack! tickle is an userpace based traffic shaper. It just redirects the socket related library funktions to allow shaping of the bandwith usage of single applications. All this is done without root privileges. Wow!
