I wonder how they did that…
Today we’re announcing CoVim, a plugin that adds multi-user, real-time collaboration to your favorite (or least favorite) text editor. CoVim allows you to remotely code, write, edit, and collaborate, all within your custom Vim configuration. Originally started as a senior capstone project for Tufts University, we’re now open-sourcing it to give the world one of Vim’s most requested features. Think Google Docs for Vim.
I’ve been getting a handful of emails offering me front-end jobs recently. Probably about time I admit that I like spending most of my time doing that, even though I ♥ my Rubies and I still believe developers who specialise end up worse off.
So I’ve decided to put down in words some thoughts…
Due to the license being not completely free, the standard MIBs are no longer included with Debian and Ubuntu, as described by this ‘bug’ report.
You can fix that as follows:
sudo aptitude install snmp-mibs-downloader
Once you’ve done that you can query devices that support SNMP. My switch, for example, can be queried for some basic info about traffic that went through its ports:
snmpwalk -v1 -c public 10.192.168.252 IF-MIB::ifInOctets
snmpwalk -v1 -c public 10.192.168.252 IF-MIB::ifOutOctets
snmpwalk -v1 -c public 10.192.168.252 IF-MIB::ifDescr
You might be interested in other metrics, have a look at RFC 2863 to find more.
The Hurricane Electric IPv6 Certification program. It’s free and it’s a fun and effective way to familiarize yourself with IPv6 concepts. Highly recommended for any technical person that has anything to do with ‘the Internet’.
If you don’t, I am confident you’ll build solutions for your clients that will at least partially break for IPv6-only users. And the changes you need to make to avoid this are small. The IPv6 certification programme (which I see more as a hands-on self-paced training lab) will help you point out what they are.
Your brain has to be IPv6 ready.
By the way, you get an ugly badge that you can show off with, FWIW. Here’s mine. :)

I have ubuntu running in a few virtual machines, and I have them at about 8 GB in size because that’s how big a default ubuntu server install is.
For some reason the default install also has the kernel header sources included, which didn’t seem very relevant to me. I decided to check out what packages I could also remove, and it turns out that my SERVER install also includes wireless support! Not very useful, certainly not in a virtual machine. So I removed it:
sudo apt-get remove wireless-crda
