history meme

On my workstation, which is one of two machines I use:

[muks@jurassic ~]$ uname -a

Linux jurassic 2.6.24.4-64.fc8 #1 SMP Sat Mar 29 09:15:49 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

[muks@jurassic ~]$ history | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head

326 ls

168 cd

92 git

74 clear

66 joe

30 grep

28 svn

15 ssh

15 cat

13 cp

I seem to use clear a lot!

So the nerd is “in” now?

Touch my body has hit #1 this week on the Billboard 100. She has all of my 99 cents. The song is a tune and it seems we’re the demographic (you’ll have to watch the video for that).

What the heck is 802.11n? You don’t want me to compile your kernel?

Try Sparse

Try Sparse to analyze your C code. Unlike Splint, it works well with the GTK libraries and reports a wide range of issues. It also neatly fits in with the autotools build system, so you can basically run your autotools and prep for a make, and then call:

make CC=cgcc

cgcc is a wrapper which invokes sparse first, and then gcc. Then go through the warnings and fix them.

SMB/CIFS file migration engine

For the last 9 months, I’ve been working on a SMB/CIFS virtualization product at Brocade. We announced this product to the world yesterday.

FME lets sysadmins migrate open files (holding rangelocks and oplocks) that are being used by client applications in a DFS namespace, from one filer to another without disruption. Hence the name virtualization. Client applications don’t know that files are being moved at the remote end. My work has been in the CIFS datapath, tracking and restoring open file metadata such as rangelocks and oplocks, and also helping migration processes track changes in a file’s data while it’s being migrated. It’d be very cool to a network filesystem developer or even a sysadmin, to see a Wireshark packet capture of the orchestrated steps.

This work was, for various reasons, done in Windows land, as a driver. Yes, I know.. ugh yuck bleh, but I got to explore a bit of Windows land :).
