What is a trolley? (link)

Posted by Aaron Minard

I recently found a great set of posts about what a trolley is and how they work at Nathan Vass' website.  The short version is that a trolley is an electric bus that gets its power from overhead lines.  There are many advantages to using a bus with rubber tires over a train (can change lanes, can avoid obstacles, climb hills without wheel-spin) and many advantages to using an electric bus over a diesel bus, the main reason being torque to climb the hills of San Francisco.

Part i is here
Part ii is here

I originally became interested in the topic last year when I visited San Francisco.  There were many things I liked about the city that appealed to different interests of mine (city planning, green spaces, diverse cultures), but one of the things that stuck out to me was the infrastructure for the trolley system.  This was not something I had expected.

When you look up while downtown, just below the common sight of power lines at the top of the utility poles, you see what looks at first like a rats nest of electric wires.  This is especially so around intersections in the road.  But upon further examination, patterns emerge.  I noticed that the wires were running in pairs of parallel tracks, and where one track crossed another, one of the pairs would have some extra hardware.

I only spent a moment trying to figure out what they could be used for when one of the Muni buses (a trolley) passed me on the street.  These are quiet, exhaust-smell free giants of public transportation that I was instantly in love with.  And this post isn't about public transportation overall, but if you need an explanation as to why it is good and how a bus can greatly reduce congestion, this GIF explains it beautifully.

DIY: Screen Printing Laboratory B T-shirts

Posted by Jesse Krembs

Members Julia & Kevin have spent the last two nights furiously handing silk screening new Laboratory B t-shirts!  Everything in this proccess is pretty much done by hand. From the printing of the screen, to printing up the shirts, to letting them air dry, ironing and then fixing any mistakes. The shirts aren't perfect in everyway but that's what DIY often looks like. You can pick one up at the Lab or at Champlain Mini Maker Fairethis weekend!

The Laboratory B will be running our awesome learn to solder station at Champlain Mini Maker Faire . We've got a bunch of kits to learn to solder with, and we might even be having some Arduino fun! We look forward to seeing you there!

Explain Shell

Posted by Jesse Krembs

explainshellWhen you first start using Unix based systems you quickly learn about the wonderful world the Unix command shell. One of the first commands you also learn about with "ls", "cd" and "cat" is "man". Man is short for manual and almost all unix commands come with a man page. Manual pages are usually quite informative about what the command does and all the options, but sometimes it's really hard to sort out. This can lead to trouble and frustration (boo!)
If you're anything like me you might occasionally have a problem with your computer and someone will tell you to run some command with a bunch of flags.. say "iptables -A INPUT -i eth0 -s ip-to-block -j DROP " or "rm -rf /" now you could run this run this or you could pass it to explain shell to help you sort out exactly what a command does. This is also really useful for commands where input is piped from one command to another.

Also check out this article about copy and pasting from the web.

Join #laboratoryb on freenode, and make crank calls with our bot ‘whistler’

Posted by Doug Smith

d00dz* do you rock out on IRC? If you don't... You're missing out on one of the pure joys of geekdom, one of the original forms of the hacker dungeon in cyberspace. And you don't have to be a rocket scientist / brain surgeon / Ada programmer  / BIOS reverse engineer -- you just have to download an IRC client**, or use one on the web (which is even easier) and for server use irc.freenode.net, and then join #laboratoryb (you do know that the hashtag originated from IRC channels, right!?)

Then! You can make all the obnoxious prank calls you want with our friendly*** bot Whistler! He's our IRC robot who's hooked up to our Asterisk box at the lab, and he's got functionality which does a text-to-speech and originates a call to a phone number of your choosing to harangue your friends, foes, or send an "I love you" to your mom from a robot (moms love that, kinda?)

But, the best part is... He's open source! You can check out all his node.js code on Google Code. So if you want to, you can set up your own instance, or get your hands dirty and improve your skill with node.js by adding feature and improving him.

* And dud3773s, of course.
** May I suggest irssi if you're a linux geek who likes the CLI, or Quassel if you're a GUI person (no shame, of course)
*** He might mom joke you now and again, and we hope he hasn't become sentient.
