Yubico is awesome

Yubico and their products are awesome.

That pretty much sums up this blog post but I'm going to go on anyway. If you're thinking of introducing two-factor authentication to your company, or you're using something that's fundamentally broken (like RSA SecureID) you simply must at least take Yubikeys into consideration.

gettimeofday() should never be used to measure time

gettimeofday() and time() should only be used to get the current time if the current wall-clock time is actually what you want. They should never be used to measure time or schedule an event X time into the future.

tlssh - a replacement for SSH

I've started writing a replacement for SSH.

Why? Because SSH has some drawbacks that sometimes annoy me. I also wanted an authentication scheme that's more similar to SSL/TLS than what SSH does.

With tlssh you don't specify username or password, you simply connect to the server using a client-side certificate to log in as the user specified in the certificate. No interaction until you reach the shell prompt on the server.

Redirecting to the closest site using Javascript

I'm sure this problem has been solved this way many times before, but I haven't seen it while idly browsing around sites about scalability and load balancing. So here it is, a Javascript solution to the closest-site problem.

10 years of maintaining an open source program

Arping 0.1 was released 10 years ago last month or so. It's since been included as a package in Debian GNU/Linux, Ubuntu, OpenBSD, FreeBSD and NetBSD, Gentoo and some other smaller and bigger OSs and distributions.

Clipboard sniffer

Yes clipboard, not keyboard. I've made a clipboard sniffer for X called ClipSniff.

It periodically saves whatever is in the clipboard (both the "PRIMARY" and the "CLIPBOARD") into a sqlite database.

Lightwave. Like Google Wave only much less

I felt sorry for all those who don't yet have a Google Wave account, and I was impressed with their demo. And I also wanted an Erlang project.

So I killed three birds with one stone. I made Lightwave. It's like Google Wave only:

• Dumber
• Buggier
• Uglier
• More incomplete
• Written in Erlang

Autotools is nice

I was recently asked why autotools was so good. I thought I might as well post what I answered.

Moving a process to another terminal

I've always wanted to be able to move a process from one terminal to another. For example if I've started a long-running foreground process (such as irssi or scp) outside of a screen and I have to log out my local terminal. I looked around and there doesn't seem to be any way to do this.

Erlang BGP daemon

I'm writing a BGP daemon in Erlang. It can connect, parse update packets and announce routes.
