So, I created a new iPhone application called uWarranty. It used an unpublished Apple API for warranty status (from selfsolve.apple.com), and so I got this after submitting it:
Thank you for submitting your application to the App Store. Unfortunately, your application, uWarranty, cannot be added to the App Store because it violates section 3.3.7 of the iPhone Developer Program License Agreement:
“Applications may not perform any functions or link to any content or use any robot, spider, site search or other retrieval application or device to scrape, retrieve or index services provided by Apple or its licensors, or to collect, disseminate or use information about users for any unauthorized purpose.”
OK, I get it. That’s fine and is Apple’s prerogative. But now I have this program and all the development time that went into it. So what do I do? I guess the answer is to open-source it, just like AppSales Mobile. Watch this space for more details as I clean up the code and throw it up on a public repository somewhere.

Jeff KelleyMiscellania AppleScript, bash, browsers, Chromium, Google, launchd, Mac OS X, open-source, scripting
I’ve been checking out the snapshots of Chromium recently, and they’re coming quicker than you can say “multithreaded web browser.” To facilitate always having the latest version, I wrote a quick LaunchAgent that takes care of it on Mac OS X. First, I have a script named ~/bin/chromiupdate:
#!/bin/bash
# Downloads the latest version of Chromium.
remove_working_dir()
{
rm -rf "${WORKING_DIR}"
exit 0
}
USER_DIR=$(dscl . -read /Users/$(whoami) NFSHomeDirectory | awk '{ print $2 }')
USER_APP_DIR="${USER_DIR}/Applications"
CHROMIUM_DIR="${USER_APP_DIR}/Chromium.app"
LATEST_URL="http://build.chromium.org/buildbot/snapshots/sub-rel-mac/LATEST"
TMP_DIR="/private/tmp"
WORKING_DIR="${TMP_DIR}/.chromium_launchd"
URL_BEGIN="http://build.chromium.org/buildbot/snapshots/sub-rel-mac"
if [ ! -d "${CHROMIUM_DIR}" ]; then
mkdir -p "${CHROMIUM_DIR}"
fi
INSTALLED_VERSION="$(defaults read "${CHROMIUM_DIR}/Contents/Info" SVNRevision)"
VERSION=$(curl "${LATEST_URL}")
if [ "${VERSION}" != "${INSTALLED_VERSION}" ]; then
logger Installed Chromium version \(${INSTALLED_VERSION}\) does not equal \
latest version \(${VERSION}\), updating now...
mkdir "${WORKING_DIR}" || exit 1
trap remove_working_dir 1 2 3 6 15
cd "${WORKING_DIR}" || exit 1
curl -O "${URL_BEGIN}/${VERSION}/chrome-mac.zip"
unzip chrome-mac.zip
rsync -HavP --exclude="Contents/MacOS/chrome_debug.log" \
"${WORKING_DIR}/chrome-mac/Chromium.app/" "${CHROMIUM_DIR}/"
if [ "$(ps -aef | grep -i chromium | grep -v grep)" != "" ]; then
open "${USER_DIR}/Library/Scripts/Chromium Update Dialog.app"
fi
logger "Chromium update complete. Version ${VERSION} installed."
remove_working_dir
else
logger Installed Chromium version \(${INSTALLED_VERSION}\) is up-to-date. \
No action needed.
fi
exit 0
Next, I have a property list named ~/Library/LaunchAgents/com.slaunchaman.chromium.plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN http://www.apple.com/DTDs/PropertyList-1.0.dtd >
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.slaunchaman.chromium</string>
<key>Program</key>
<string>/Users/slauncha/bin/chromiupdate</string>
<key>KeepAlive</key>
<false/>
<key>StartInterval</key>
<integer>3600</integer>
<key>RunAtLoad</key>
<true/>
<key>StandardOutPath</key>
<string>/dev/null</string>
<key>StandardErrorPath</key>
<string>/dev/null</string>
</dict>
</plist>
Finally, I have an AppleScript at ~/Library/Scripts/Chromium Update Dialog.app:
display dialog "Chromium was just updated. You should restart it."
The LaunchAgent runs once an hour, checking to see if the installed version of Chromium is older than the latest snapshot. If so, it downloads it and uses rsync to copy the changes. The script places Chromium in ~/Applications, but it shouldn’t be hard to modify to put it into /Applications.

Jeff KelleyMac Tips command-line, Mac OS X, open-source, Synergy
So here’s an annoyance. Having just installed SynergyKM, a great front-end for the awesome command-line utility Synergy, launching it would result in the following prompt:
The promt you get when launching SynergyKM
To fix this, you need to remove the extended attribute com.apple.quarantine that’s on the file. Fire up Terminal and enter the following commands:
sudo xattr -d com.apple.quarantine /Library/PreferencePanes/SynergyKM.prefPane/Contents/Resources/Synergyd.app
sudo xattr -d com.apple.quarantine /Library/PreferencePanes/SynergyKM.prefPane/Contents/Resources/Synergyd.app/Contents/MacOS/Synergyd
That will remove the flags and prevent the prompt.
Normally, you’d only see this prompt once, but since installing it for all users changes permissions such that your user account can’t remove the attribute, it isn’t removed.
Note: This is assuming that you’ve installed it for all users. If you’ve installed it for one user, it’ll be in ~/Library, not /Library.
Update: I’ve submitted a patch to SynergyKM’s SourceForge page, so if they accept it this will no longer be an issue.
