Slack Line

Last week I decided to get out my climbing gear and set up a slack line between two trees in the Quad here at UW so that one of my buddies and I could see how hard it was.

It was very VERY hard.

Over the course of probably about an hour and a half, I managed to be able to balance on it for a a total of four seconds at a time. I was pretty happy with that.

My buddy only managed a max of about half a second of contiguous balancing. That was, of course, after he decided to do something stupid. After I told him not to, and that it was ludicrously stupid, he decided to try and to a handstand on the slack line. The even sillier thing? He can’t do a handstand on solid ground. So he goes for it, does about half a cartwheel, and then buckles and falls on his side, on his arm, which knocks the wind out of him, and I can’t help but laugh.

That’s the horrible thing about those situations, you make sure they’re mostly ok, and then you laugh your head off at them. Gasping for air, between rolls of laughter, I attempted a few times to get out an “I’m sorry!” or an “Are you O.K.?” It barely worked.

By any means, he survived, and decided afterward that it was a really stupid idea, and he would definitely not attempt that again.

Ah, the fun of a slack line.

SmokePing

So, recently I installed an open source latency tester/grapher called SmokePing. It’s from the same guy that made MRTG (Multi Router Traffic Grapher). I’ve long wanted to install a copy to test the reliability of my wifi router at home, as I’ve previously had problems with it. I decided while I was at it, I would have it test my systems here at UW, the DN/BS server, and my systems/connection at home. One convenient thing about SmokePing is that you can perform remote tests via an ssh connection. The system is testing each system with 10 pings every 60 seconds. Here are some screenshots of the resulting graphs.

This is a graph of the connection to my wifi router here at UW. You can see it’s pretty solid in terms of time and packet loss.

This is a graph of the connection from my firewall at home, to my connection via wifi to my ISP’s tower on the ridge. You can see that under high load times we get lots of high latency problems, especially after seven! Also note the high packet loss. This tends to cause very slow connections. How unfortunate!

This is the connection from here at UW to the firewall at home, which strongly correlates to the connection from the firewall to the ridge. Thus the latency and packet loss here is also EXTREMELY HIGH.

Learning Dvorak

Alright, like the title says I’m trying to learn to type via a Dvorak key layout. So far it is rather difficult. For instance, this has taken me seven minutes to write so far. But I can tell that I am getting faster. Check out more info at wikipedia.

Vehicular Relay System

Well, this one is a little delayed, but a while back I started on a project to create a relay box to go in my truck to manage turning on and off things like my amp, cb, power inverter, etc. all from one location without having to reach around all over the cab to manage the various devices.

The control box I have right now only controls three of the relays, and this control box will live in my truck, but the relay box is capable of switching up to seven devices. This way I can use another control box, and quickly grab the relay box from my truck and use it for various other purposes.

I chose to use a standard ethernet cable to handle the connection between the control box and the relay box because of it’s convenient management of 8 wire. This allows for one to act as ground and the rest to send a small voltage to each relay. The power is fed in from the control box, that way only one wire needs to run to the relay box for operations.

Concerts and Hosting Changes

Well, it’s been a busy but interesting past two days for me.

Yesterday, my dad and step-mother surprised my girlfriend and I with tickets to go see Great Big Sea. If you’re not familiar with them, I’d describe them as Folk Rock. They’re from Newfoundland and have some really fun music. So we went to the concert last night where they played two full sets and two encores totaling to a really fun time.

Then today I’ve spent a good chunk of time getting all of our various websites moved to a new host. We sold our high profile site, so we no longer needed the horsepower of a dedicated (and expensive) Solaris box. Unfortunately this means that I needed to get the new host all set up to handle the various sites, upload all the content, and then go through every file to make sure the links were all still working properly. I’m pretty proud to say that I’m pretty much done.
