Psychologist Robert Chaldini described how there are two types of social norms, descriptive norms and injuctive norms. A descriptive norm informs by way of example or suggests what is commonly done. An injunctive norm directs us toward what ought to be done; toward what is socially approved or disapproved. It all sounds pretty boring and psycho-babblish, but once you understand the implications, it is surprisingly useful.
If I think these norms in the way things are marketed, especially around our church, I can see why many marketing campaigns fail. For example, we regularly tell people that they "should" get involved in a ministry area or a small group. Yet we know for a fact that people almost never get involved in anything because they "should". It's almost always because one or more friends invite them or especially when they see many people that they know getting involved. The "should" is the injunctive norm and just doesn't have much of an impact on people. The "everyone is doing it" is a descriptive norm and is the one that really has an impact.
I can really see the difference when I look at campaigns we've run, even if I just look at what my reaction to them has been. I assure you that when I hear anything like a "you should ..." or "we'd like everyone to ...", I don't respond in any positive way. But when I hear things like "250 members already signed up ...", it really gets my attention. I really didn't make a firm commitment to joining a small group until I realized that most of the guys I knew at church were in one. Whenever someone invites us to an event, we want to know who else is going. I almost skipped my second men's retreat a couple years ago but decided to go after looking at the list of who else was going.
The worst thing we can do, and we've done this repeatedly, is to try to encourage people to go by announcing that not many people have signed up yet. If anything we need to say that we may run out of space.

So what's on my Treo? So much stuff I won't even list it.
In any given week, here is what I might do with my Treo.
Make phone calls. It's at least as good of a cell phone as my last two, getting good coverage and reasonable battery life. The contact management is pretty good and for once I didn't have to spend hours updating my new cell phone with my contact list from my Palm. I'm still not using a Bluetooth headset, mostly because I just don't make that many calls.
Listen to MP3s. I've had a small set of MP3 music on my Palm for a few years now, mostly to use to drown out background noise while I read, work, or study. Now I've expanded that set (thanks to today's huge SD cards) to include more music just for listening or while walking. I've also started loading up podcasts. I mostly listen to them in the car with an FM transmitter, but now I can fire up my Treo and listen to a podcast anywhere. With PocketTunes I can even set a 15 minute sleep timer and fall asleep to some boring NPR show.
Manage my todo list. As I try to follow Getting Things Done, I've been tweaking my Palm's todo list to fit how I work. Now I have several lists for different contexts (Home, Work, Errands and Store plus Waiting For and a general Next Action). By trying really hard to dump random thoughts into there, I'm really getting less surprises and spending less time trying to remember some random thought. If I need dish soap, it goes in the Treo and I forget all about it until I'm at the store.
Calendar. I have a really weak calendar system because it's spread over three systems. I have an Outlook/Exchange system at work which mostly has work stuff and Google Calendar for all my personal stuff plus the rest of my family and other events like football games and Brownies. Since I really don't sync my Treo at all, I don't keep it in synch with either of those calendars, so all that's on my Treo are the important reminders and GTD actions that have a date trigger. Unfortunately, that just isn't working too well. I need to get it synched with at least my Google calendar.
Offline websites. I've got a decent collection of websites that I've packaged using Plucker and Sunrise Desktop. It's great to have MousePlanet on my Palm when we're trying to decide on the fly if a Disney restaurant is worth trying or if at check-in time, it's worth upgrading to a different resort. I also carry Bruce Eckel's Thinking In ... series to constantly keep relearning patterns, Java, C#, C++ etc.
Bible. I use MyBible to carry several different bible translations on my Palm. They now have NIV Study Bible notes and the Life Application Study Bible notes as well as almost every current translation. It's great to be able to flip back and forth between translations and compare. The software also supports hilighting and taking notes but I don't make use of that.

The hook that got me to read the article was Stephen's criticism of Bono in his new book Usual Suspect.
I just watched Bono a couple of months ago in a taped interview at the 2006 Leadership Summit and he blew me away. Bono talked about his faith and how much he doesn't want to be like Christians.
I even felt like Bono was holding back and I really wanted him to speak his mind. Bill Hybels wrapped up the interview by asking Bono if he had anything that he'd really like to say to 15,000 pastors and other leaders around the world. Bono actually looked intimidated and I swear he backed away from what he really wanted to say. I was so hoping that he'd just unload on them -- us.
So back to Stephen and his world view. He apparently criticizes Bono for not being a sold-out gospel-preaching evangelist instead of what he is, which is a rock star. Stephen apparently thinks it's a waste for Bono to campaign for debt relief for Africa. Maybe Baldwin's wife can read him some of the many biblical references about usury. Bono quoted an amazing statistic. Live Aid raised about $250 million, but the same African countries now owe over $250 billion. Their annual debt payments completely dwarf any money we spend on humanitarian aid.

I started with some different batteries and measuring the voltages on them. Then I took a 6 volt bulb and applied the different voltages to it so they could see how bright it was. Then we applied more and more voltage to the bulb until it finally died. It took almost 20 volts from some some pretty high-current sources (a big AGM lead-acid battery and a pack of NiMH rechargeables), but it finally burned out. Then we talked a little about what's inside the light bulb that burned out. One of the kids even beat me to it and told everyone else that there's no air inside the bulb. Then I did the demo that I was worried about. My big lead-acid battery, jumper cables, and some steel wire. I knew I should have put down some foil or something to catch the hot wire, but I didn't. The wire burned to a crisp immediately and fell right on the table-top, melting a nice line into the new table. Did you know that light-colored Formica table-tops have only a thin layer of light material over a dark base? I do now.
Then I went on to talk about different conductors and resistance. The big demo there was dropping some clip leads into a cup of water and adding salt until the light bulb lit. It started sort of cool for the kids, especially since they'd played with chemistry the week before. But then they got a bonus electro-chemistry demonstration as the tin plating dissolved from the anode alligator clip and the water turned an "awesome!" brown color accompanied by a steady stream of bubbles. I knew I'd get a little of that, but I didn't think it would be that much. They thought it was cool.
Then my big finale was passing out little LED keychain lights (RadioShack clearance). We had a little talk about being responsible with lights and electricity, then it was time to go.
We had a somewhat disappointing attendance this week and might have even had a few less kids than the week before. But looking around the room, I could tell that we had a lot of different kids this week than we had last week. Something I've learned is that there's no good way to predict or even understand attendance fluctuations like that. Sometimes we just have a "down" night where even a lot of the regulars miss, and we usually can't explain it.
I'm pretty excited about the future of Detour. We keep hearing great comments from kids and parents and people keep coming up with good ideas for 4-week workshop topics for kids. We've got some really great ones lined up for later in the year, especially in the spring when more teachers can make the commitment.

For months, I've been meaning to but some plastic bins for the kitchen cabinets to hold spices and other stuff on the higher shelves. We have some temporary bins that are a little too big to let the doors close, so I needed to get some different ones. But the job just wasn't getting done. On my "@store" ToDo list on my Treo I have "bins for kitchen cabinets". So early in the week I stop at the selection of plastic bins and I realize I have no idea if what I'm looking at will fit. I'd hoped to find the same bins we already have and just buy something a little smaller, but no luck. So I had to go back to my ToDo list and add "measure cabinets for bins" to my "@home" list. Now that I've got them measured, the project is back on my "at the store" list and should go pretty easy. As long as I can find a ruler in the store...
It was such a simple project, but by getting the right steps down and getting them set up on the right contexts, it all flows smoothly.

I reduced the contrast. At work my LCD was turned up as bright as it would go, so I reduced the brightness and contrast to just above the point that I thought it was too dark. At home I like to work most of the time without much light in the room, so even though the LCD brightness wasn't cranked way up, it still had a lot of contrast with the rest of the room. So now I try to work with a light on in the room. I'm looking for a small, cool light to put behind my monitor to reduce the contrast with the background.
I also switched my primary text editor, Vim, to a white on black color scheme instead of black on white. I was already using similar white/green/grey on black for all my terminals, 3270 sessions, Windows consoles, etc., but I spend at least half my day staring at Vim. Maybe I need to look at some of the web apps where I spend a lot of time, like Jira, and swap the color scheme on those.
Between those two changes, my eyes feel a lot better now, even though I had to spend even more time working lately.

I had to fill in at the last minute for the science teacher, so we mostly worked with vinegar and baking soda. Most kids past first grade have seen it bubble over and half of the kids had built the typical volcanoes. So I filled up some Ziploc sandwich bags and got them to explode, which was a little more exciting. I didn't get time to find some soap bubbles to try another trick I'd read about online yesterday. You build up a big pool of CO2 in a dishpan or some other tub. Then you blow soap bubbles over it. The CO2 is heaver than room air and tends to stay in the container pretty well. Since the bubbles are filled with room air, they'll float on the CO2 layer instead of sinking. It sounds neat enough that I still want to go back and try it with the kids. Maybe next week, but I think we're going to do electricity, light bulbs, LEDs, etc. Maybe some radio stuff?
Last night went pretty smooth considering that it was the first night. A lot smoother than the first night of Pioneer Club last year. I heard that we got a lot of positive feedback from parents and kids. The new remodelled space for the kids is looking amazing and it's still not quite finished. I really need to get some photos as areas get completed.

Maybe it's a sin to gamble. Okay. But it's an even greater sin not to accept the fact that we are sinners. The government ought to book that bet.
I thought that was an interesting new-but-old take on this argument.

What's so great about GTD? There are essentially two main points. Get everything you need to do out of your head and put it down on paper.
Before I started following this, I can't tell you how many times an hour I'd remember something I needed to do. Sitting in my car on the way home I'd remember things I needed to do at work. Or I'd be in the shower and remember that I needed more gas for the lawnmower. Or at dinner with my family and remember that I needed to buy a new tube of toothpaste. All those little reminders would just float around in my head. Some would make it into my Todo list on my Treo, but not enough. Now whenever I think of anything new I need to get done, it goes into my system. Most of the todo's go into my Treo, organized by context. So when I'm at the computer, I've got a list of emails to send and things to look up. Or when I'm at the hardware store, I've got a shopping list of whatever I've thought of over the past few weeks. Longer-term or bigger things go into a document on my computer for me to plan out the individual actions. Or in a pinch, I write it on an index card or scrap of paper and make sure I get it into my "system" as soon as I can.
The other big idea from GTD is to really figure out the "next action" of your todo items. Like "clean the house" isn't an action. It's a project. A project that'll never get started until you start with an individual action. Listing out the action steps on a project helps a lot. I've always done that for major projects, but I've never considered how not doing that for seeming little things like buying a new digital camera can stall that project. Without discovering actions like "research cameras online" first, that todo would just sit and sit on my list. I'd look at digital cameras whenever I was out, but never get around to making a decision because when I was online, it wouldn't occur to me to look up digital cameras.
There is more to the book than just those two points, but they're the big ones as far as I'm concerned. It's definately worth reading.

These days I alternate between Knoppix and Damn Small Linux, depending on what I need from the machine or how old and slow it is. I carry a 1 gig USB key anyways, so I can save off anything I need to keep or work on.
With a mini-CDR of Damn Small Linux, a Linksys WPC-11 wifi card, and my USB key, I can pick up pretty much any old laptop with a CD-ROM drive and boot it up into a useable environment.

* Troubleshot a EBCDIC codepage problem transferring IFS files on a i5 / iSeries / AS/400 machine.
* Built a circular log file tool on a HP (Tandem) Non-Stop Kernel machine.
* Recovered an old UltraSparc machine running Solaris 2.5 for use in some testing.
* Tested and fixed problems in our product on z/OS.
* Troubleshot a problem with our defect tracking web service, which I finally tracked down to a bad ethernet cable to the switch.
* Repaired the wiring for our magnetic lock / keycard door.
If I go back a few weeks, it gets even more diverse:
* Code and test a new release on AIX, Solaris, z/OS, and Windows. (Which also runs on i5, HP-UX, and Linux).
* Tested and supported a stripped-down version of our product on IBM 4690, a point-of-sale system that's sort of cross between CPM and OS/2.
* Troubleshot a problem using an undocumented Windows API on Windows Server 2003, including problems with access rights on domain users.
* Rewrote a major portion of our I/O routines for z/OS.
* Done basic system administration on AIX and Solaris.
I found that Solaris has a loopback driver that let me mount the cd image:
mount -F hsfs -o ro `lofiadm -a unix.iso` /mnt/iso
then when you unmount, you have to remember to tear down the loopback device you created:
lofiadm -d unix.iso

Every day I end up with at least a half-dozen PuTTY sessions open to various unix and other POSIX-ish boxes. By default PuTTY titles each window with the hostname, but when I have multiple sessions to a single box, it's hard to keep them straight. I was happy to see that PuTTY handles the same title escape sequence as xterm, so you can programmatically change the window title from the host you're connected to.
Just set up an alias, function, shell script, .profile, or even your $PROMPT to echo the right sequence and you'll be able to title your windows, whether they're PuTTY sessions, xterms, Gnome terminals, or almost any other Linux terminal session package.
The sequence is: <esc>]0;<title><bel> where <esc> is the escape key, 0 is a zero, <bel> is control-G and <title> is the title you want to set.
