Getting Your Boss To Buy Lava Lamps

Posted by michael on Thu Aug 26, 2004 12:45 PM
from the boogie-down dept.
jarich writes "Mike Clark's blog provides directions and code on how to wire up lava lamps to your build system. When a compile or test fails, the red lava lamp gets switched on... The delay in the lamp heating up gives you a few minutes to fix things before it becomes obvious to co-workers that you broke the build. His example uses CruiseControl but you could easily modify it. Very cool stuff and inexpensive to setup."

      What the practice of software development really needs is some way to assign blame to people and keep them under pressure to get things right. Right?

      Hooking a computer up to a lava lamp is neat (however not as cool as the Ambient Orb [ambientdevices.com]), but treating programmers like Pavlovian dogs is ridiculous.

        In professional radio, they always have lights hooked up to the phone line, because, obviously, it would sound like shit to have the phone suddenly ringing when you're on the air.

        My boss had a thing with people not answering the phone, so the phone light moved from being a modified desk lamp, to being a strobe light, to being two strobe lights, to being two strobe lights and a red rotating police light.

        All this being said, and since I know for a fact its a pretty easy electrical hack, why stop with a silly lava lamp? If my old General Manager was in IT these days, a failed build would result in a temporarily blind and deaf dev team, and an office space that would occasionally have the lighting and decible range of a metal concert.

      That might not be a bad idea for a casemod on some of the latest P4s. Run a heat pipe from the CPU over to a lava lamp.

      However, IIRC a lava lamp works with just a 40W bulb. With some of the latest CPUs throwing off >200W of heat, you might need a whole row of lava lamps on top of the machine. Maybe the entire side of the case could be filled with gloop and made into a wall of lava.

      Lets say somehow you convince your boss to buy you one. How long are you going to spend hooking it up. Then how long are you going to spend hooking it up to other things (it must be raining out, the green lamp is on and the red is off). Then how long are you going to spend testing the other apps you've hooked it up to. (New story on slashdot, both lamps are on!).

      Once the lavalamp works, you should be able to upgrade to shock collars for all the developers pretty easily. Talk about incentive to not screw up. After this upgrade plastic covers for everyone's chair might not be a bad idea either.

      X-10 hardware and X10.com are not the same thing. The former is hardware based on a protocol that was invented in the early 70s. The latter is a company that just happens to make technology based on the protocol.

      One doesn't necessarily have to come from the other, and it's a shame that the vendor has ruined a perfectly useful technology, even shaming it doubly by making poor-quality electronics.

    Most environments in which I coded would prefer a Room 101 model. A cage is placed on your head. When the build is broken, rats are released into the cage. The time it takes the rats to run down the tunnel and into the cage to eat your face gives you time to fix your mistake.... The lava lamp version sounds double-plus good.

      Better make sure you specify wild rats. If they were fancy rats, they'd probably just lick your nose or snuffle in your ear or something. Then you might want to break the build on purpose just for giggles.

    CruiseControl [sourceforge.net] is a continuous integration tool. Mostly it's for Java but there's a .NET port too. Basically, it regularly compiles a code base to make sure no one broke anything with their commits. Apache uses something similar called GUMP [apache.org].

    Bubble, Bubble, Build's In Trouble
    Your software is being automatically built and tested on a schedule. It even sends you an email when the code doesn't compile or pass its tests. You're certainly ahead of most projects, but email is just so 90s. Even if you could manage to find those build failure emails amidst all that spam, you're reading yesterday's news. Indeed, you may already be ignoring the status of the scheduled build.

    The Monitoring chapter of the book offers alternative, in-your-face, worth-getting-up-for-in-the-morning techniques for monitoring scheduled builds. The most popular technique came by way of a story contributed by Alberto Savoia. He describes how his project uses red and green lava lamps to radiate the status of their scheduled build. Better yet, those lamps are controlled using X10 devices such as those used to turn on your household lamps so that you don't arrive home to a dark house.

    Well, as you might imagine, I could hardly wait to build my very own build-monitoring lava lamp kit. And as bonus material for readers of the book, I've crafted a bit o' software that integrates with CruiseControl. So now you too can enjoy red and green bubbles on your project!


    Bill of Materials

    To get started, you need some automation gear. Think of these gadgets as this year's essential project accessories:

    * 4-Piece Firecracker Automation System

    This kit includes:
    o 1 Firecracker Computer Interface
    o 1 Transceiver Module
    o 1 Lamp Module
    o 1 Palm Pad Remote Control

    Cost: $39.99

    (Props go to the folks at x10.com for supporting this project by supplying me with a complimentary kit. It all fits in a wee box, so I can carry it from project to project.)

    With that kit, you can control two lava lamps -- one plugged into the transceiver module and the other plugged into the lamp module. You can optionally purchase another appliance module if you want to control two appliances. For example, you might want your build process to turn on a coffee pot when the build fails and then kick start your margarita machine when the build is fixed.
    * 2 lamps, preferably the kind that boil red and green lava

    I used the Hot Rock Lite F/X (yellow earth/blue liquid and red earth/purple liquid). Note for legal purposes that these lamps (shown in pictures below) are not LAVA(R) brand motion lamps, but those will work just as well.

    Cost: $9.99 each at Target or Walmart
    * Pragmatic Automation X10 software
    It's an open source Java library that includes the CruiseControl plug-in, an API to make your wildest X10 dreams come true, detailed instructions, and an ever-so-useful collection of tests.

    Way down deep, the library uses the Java Communications API to send bits out over the serial port and into the Firecracker Computer Interface. (Linux users will need the RXTX implementation). Michel Dalal's Java X10 CM17A API library, an implementation of the FireCracker (CM17A) Communications Specification, is used to send out the correct 1s and 0s in response to human-friendly commands. Many thanks to him for doing all the low-level bit twiddling and sharing the goodies with us!

    Cost: Free to readers of Pragmatic Project Automation

    Assembling the Kit

    With that hardware in hand, you're ready to start the assembly process. The Firecracker Automation System includes instructions written for your average home electronics consumer, so your average computer/network geek should have no trouble. I'll spare you all the gory details and instead run through a quick visual tutorial of my setup.

    Start by plugging the Firecracker Computer Interface into a serial port of your scheduled build machine:

    This little gem sends a wireless signal from the computer to the transceiver module. Notice that you don't lose the serial port. You can plug another serial device

    We had the problem of concurrent users locking up a tape drive.
    We tried a white board, we tried a sign in/out sheet, it got so bad that we held a meeting and the manager decided we would use the ownership of a certain file to show who was allowed to control the tape drive.
    The same manager broke his own rule immediately after the meeting.
    My solution was the one that worked.
    We used a really cheesy Mardi Gras necklace. Who ever had the necklace in their possession was allowed to access the tape drive. We never had a problem after that.
    If you left the necklace on your desk it was perfectly okay for someone else to steal it. If you wore the cheesy thing around your neck, everyone knew you were using the tape drive.

    Sometime low tech is easier, more reliable and best of all, funnier.

    We've got a similar system, but it uses the lava-lamp screen saver.

    If the keyboard or other input device isn't used within five minutes, a lava-lamp appears on screen.
    That way, we can tell if someone hasn't been working within the past five minutes.

    Personally, I prefer the futuristic virtual Lava Lamp office, where you're cubicle rises and falls according to how productive you have been.

    I'm not sure I would want to put in place something that would encourage designers to make quick fixes. Once the build breaks the "lava lamp penalty" would encourage a designer to keep the lamp from bubbling rather than spend the time to fix the break in the best and safest manner (i.e. one that may take an hour longer.)

    Does your build environment allow you to debug, build, and test a loadbuild break in the time it takes a lava lamp to heat up?

    That headline blurb doesn't do this book justice. I was one of the first kids on my block with a copy of this book, and I highly recommend it.

    This book is not about lava lamps (although it does talk about them). This book is about using automation to keep your software project on-track... never letting things get broken... using a computer in your office as a 'virtual employee', continually building and running unit tests and letting you know if someone breaks the build.

    Yes, there is a reference about automatically turning on a red lava lamp if your unit tests fail... but far more important than that, the build on my project (which uses the ideas from this book) is never broken long enough for a lava lamp to heat up.

    If you are interested in Agile process (especially the XP concept of 'continuous integration'), you need this book.
