Drop-down menu without javascript

Some time ago I was looking for a CSS-only (no javascript) cross-browser technique to make a drop-down expanding navigation menu. I found the GRC Menu that did this, but it had a lot of site-specific stuff in there. It was not something I could easily use as a starting point for my own sites.

So I hacked around with Steve's CSS and HTML and developed a minimal version. Here's the minimal version of GRC's script-free pure-css menu.

That doesn't happen very often

On Saturday morning I woke up to people talking about string concatenation, and how many parameters some function needed.

MS SQL matrix query

If you use Microsoft SQL and you want to do a query to turn some rows into columns, it can be tricky. I don't know what that type of query is called, I think some call it a matrix query or a cross-tab query or a pivot query. Here's how I've been able to write a pivot cross-tab matrix queries for Microsoft SQL Server including an extra variation for SQL Server 2005.

MediaWiki software and rel=nofollow

In case any of my readers run a MediaWiki site, you should know: By default, MediaWiki is configured to use rel=nofollow on links. This means anyone who sets up a MediaWiki site, not just wikipedia and its siblings. Here's more info and how to reconfigure it. That makes me mad. They should have better defaults.

Event notifications in linux

Envious of slick Mac notifications via Growl, I looked around for similar systems for linux. There doesn't seem to be anything quite as nice, but KDE has a knotify subsystem that is used by KDE apps and easily scriptable. And Galago has libnotify (or is it libgalago?) a gtk-based system for notifications.

I wanted to have an easy way to get notifications when a build or test suite is done running, so I wrote a few simple scripts to use knotify to do so. See Putting KNotify to work for some docs and screenshots of what it looks like. Here's the docs and code:

knotify-send

docs:
  Usage:
  knotify-send [TITLE] [BODY] - create a passive knotify popup

Example:
  knotify-send heya! "look at me"
code:
  #!/bin/bash

# Copyright Dave Brondsema
# licensed under Apache License 2.0

# inspired by galago-project.org's notify-send

if [ "$1" == "" ]; then
    echo "Usage:"
    full=$0
    base=${full##*/}
    echo "  $base [TITLE] [BODY] - create a passive knotify popup"
    echo
    echo "Example:"
    echo "  $base heya! \"look at me\""
    exit
fi


dcop knotify default notify eventname "$1" "$2" '' '' 16 0

knotify-done

docs:
  Usage:
  knotify-done [COMMAND] [ARGUMENTS...] - runs command with args, and then runs knotify when done

Examples:
  knotify-done svn up
  knotify-done ./configure && make && knotify-done make install
     (only notifies for 'make install')
code:
  #!/bin/bash

# Copyright Dave Brondsema
# licensed under Apache License 2.0

# inspired by http://sami.picobot.org/?p=19 and comments

if [ "$1" == "" ]; then
    echo "Usage:"
    full=$0
    base=${full##*/}
    echo "  $base [COMMAND] [ARGUMENTS...] - runs command with args, and then runs knotify when done"
    echo
    echo "Examples:"
    echo "  $base svn up"
    echo "  $base ./configure && make && $base make install"
    echo "     (only notifies for 'make install')"
    exit
fi


$@
title="Completed with exit code $?"
body=$@
dcop knotify default notify eventname "$title" "$body" '' '' 16 0

BarCampGrandRapid2 recap

BarCampGrandRapids2 was a lot of fun. I didn't get to engage quite as much as I'd've liked since I was one of the organizers, but it still went really fun and was good to meet lots of people and hang out with friends. I particularly enjoyed Calvin's and Kyle's presentation on YUI CSS and Design Eye for the IT Guy (lots of good resource links there). Hopefully I'll post some notes about my presentation on Facebook/Myspace (I said "spacebook" a few times when I was tired.. not during the presentation) and the need for open systems and protocols for social networks. Finally, I want to list off a few new people that I met. I don't know why, but I feel like doing it.

  • Anthony Oliver (xamox) - Google Summer of Code participant, hacking Drupal; also had some interest in RDF & FOAF
  • Bill Warters - from Wayne State and applying some very recent technology (yahoo pipes, grazr, simile timeline) to help faculty
  • Zach Dennis - Ruby dev, currently
  • Sean McMillan (reaper\umich/edu) - interested in a tool that could post to multiple blogs/social networks
  • Matt Michielsen - interested in lots of things, seemed to grok what I was saying about Konfidi, PGP, DKIM, SPF, etc
  • Greg Clark - bright underclassman working with Jeremy Frens on a RoR project

Does google toolbar uses hCard microformat for addresses?

It appears the the google toolbar (at least for IE) will find addresses in webpages that are marked with the hCard microformat and use it in a "Look for Map" button. I haven't tried to test it, and I can't find anyone talking about it on the web. But it sure seems to work that way. It may (also) use some other heuristics, I don't know. Does anyone know more about this?

BarCamp Grand Rapids 2

no, it's nothing (inherently) about drinking. It's a fun geeky get-together that I'm helping organize again this year. Here's the announcement with all the info:

Rule #1 of BarCamp: you DO talk about BarCamp.

http://barcamp.org/BarCampGrandRapids2

We're proud to announce our second BarCamp (dangerously close to being "annual"). BarCamp is a technology & design unconference where the campers (you) determine what's on the schedule. These ad-hoc unconferences are intense events with discussions, demos, and a chance to interact with fellow attendees. Anyone with something to contribute or with the desire to learn is welcome and invited to participate.

WHEN: Friday evening, July 20 and Saturday, July 21

WHERE: Calvin College, Grand Rapids, MI

COST: Free! But everyone is encouraged to present something and be involved, even if you're never given a talk before.

WHAT: So far, topics ranging from opensource business to the JQuery Javascript library to next generation communications. Ultimately each camper has an opportunity to help determine the content.

You can register and find out more information about BarCamp Grand Rapids at http://barcamp.org/BarCampGrandRapids2, or about BarCamps in general at http://en.wikipedia.org/wiki/BarCamp
