Making it easy to try DTrace4Linux
DTrace4Linux is an attempt (from UK developer Paul Fox, also known for his CRiSP editor) to bring the power of DTrace to Linux. It’s a kernel module (No kernel recompilation required! Yay!) and userland tools.
I did a bit of hacking around with Vagrant and Puppet and VirtualBox to make it dead easy to try.
- An OVA file for Ubuntu with DTrace4Linux kernel module already built and installed. Import the OVA into VirtualBox et al, boot it up, and try something like
sudo dtrace -l - A
.vmwaremvm that should be importable into VMware Player - Pull request with
Vagrantfile— for Vagrant
DTrace for Linux
I wanted to draw attention to the excellent work that Paul Fox has been doing in porting DTrace to Linux. And he recently created a GitHub repo for it, so it’s that much easier to contribute now.
If you have Linux kernel knowledge, I’d encourage you to get involved!
Running Dropbox on DreamHost
As promised and after a nudge from Bruce, here’s how I was able to get the Dropbox Linux CLI software running on a DreamHost VPS server. This isn’t super hard but it wasn’t a trivial install, because the Dropbox software is closed-source and it contains binaries compiled against glibc 2.4, whereas my VPS server is using glibc 2.3.
Making du report useful output for comparing across systems
You have to be a little careful using the du command to compare output across systems. For example, a few weeks ago I backed up a bunch of files from our MacBook Pro to our NAS and then was running du commands to verify that directories on the systems had the same amount of data. There is a pitfall here, though…
Ubuntu repository problem resolved
The previously mentioned Ubuntu repository problem seems to have resolved itself. I am finally able to upgrade my Samba packages.
