Timeless career dev tips, 2008 recession or not

Robert Scoble's wise words on what to do if you’re laid off in 2008 recession apply no matter what the weather...

Help me help

OK, so in an effort to "monetize" this blog, I added a Donate button yesterday (lookey over yonder ->). I'd like to donate 50% of all donations to a worthwhile cause—the other half just helps keep this site, and my webbish ambitions, alive—assuming of course there's any whole to divide up in the first place!

So come on, make a donation, then convince me why I should benefact your favourite charity.

Images missing from Windows Vista Help and Support Pages

I switched back to Vista a couple of weeks ago, after giving up trying to live in Kubuntu for the second time in a year. I noticed one minor nit after I moved back in, all of the image graphics in Vista's Help and Support pages had mysteriously disappeared, leaving only little boxes with red x's behind them. Fortunately, a quick Googling brought me to Ramesh Srinivasan's solution - a quick registry patch file, courtesy of Mr. Srinvasan, restored the help page graphics to their former glory.

Diffing where I want, and diffing the same file

I use WinMerge a lot for general interactive file diff/merge/munging. It's great, free, etc. But what I'd really like is a diff tool that a) lets *me* decide which bits in each buffer match up as the starting point, and b) let me compare two sections of the same file. Does this exist? Please let me know. Please.

Compaq Presario C500 and Kubuntu wireless networking fun

These instructions on the Ubuntu KNetworkmanager page got my Compaq Presario C500's Broadcom BCM 94311 MCG wlan interface back up and running after I fu-fiddled around with it this afternoon. I made the mistake of clicking the "Manual Configuration" option in KNetworkmanager, after which I lost all wireless connection, and couldn't find my way back out of the wireless woods:

1. Made a backup of the file /etc/network/interfaces
2. Delete all configuration settings in the file except the lo interface
   
   auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0


3. saved the file then typed /etc/init.d/networking restart
4. After enabling the laptop's wireless networking hard-button, the wired network reappeared in Networkmanager's Connection Status
5. Also followed the instructions to enable the connection to survive suspend or hibernate, and bypass the keyring password at every login
   

Setting up a Canon Pixma MP530 on Kubuntu 7.10 (Gutsy)

I started tinkering with Rails again on Vista. Boy, is Mongrel ever slow. That's what prompted me to test-drive Kubuntu in the first place. OK, let's try it again. Download the Gutsy image, repartition, reinstall... wow, it Just Works. After a minor bit of fiddling to get the sound card working, I'm up and running on Kubuntu again. Except the printing thing. Complicating the matter, the printer, a Canon Pixma MP530, is shared out from a whitebox PC running Windows XP Home.

After a bit of googling, this is what I did:

1. Following a tip on the OpenPrinting database MP530 page pointing to Brady Hunsaker's advice I downloaded the .rpm MP500 driver files from Canon's FTP site.
2. Installed alien (what a cool name, not to be confused with alien-arena) then I converted the .rpm's to .deb's and installed them.
3. Brady says create symlinks to old library names... but he doesn't explicitly say _where_, for the sake of beginners like me. After a few minutes of noobiness, I realized the symlinks should be in the same directory as the library files to which they point (`/usr/lib/`, not in the printer driver directory `/usr/share/cups/model`).
4. As a test, I plugged the printer directly into a USB port on my laptop then fired up the CUPS server on the default URL http://localhost:631/. No luck, CUPS couldn't see the printer, even after I power-cycled it.
5. I noticed one of the device options is "Windows printer via SAMBA". Hrm...
6. Followed the instructions on Debian and Windows Shared Printing mini-HOWTO to verify that my lappie can connect to the Winbox via smbclient as `smbclient -I WIN.BOX.IP.ADDRESS -L WINBOXNAME -N`.
7. Plugged the MP530 back into the Winbox, then started going through the new printer install, this time for "Windows printer via SAMBA":
1. Add new printer
2. Fill in the name, etc.
3. Device for printer: select Windows printer via SAMBA
4. URI: `smb://WINDOWS.PC.IP.ADDRESS/HOSTNAME/PRINTERNAME`
5. Browse to the PPD file in /usr/share/cups/model/canonmp500.ppd
6. When prompted, enter your Linux username and password (like sudo)
7. Configure and enjoy the printer!

I successfully test-printed a couple of pages duplexed from a PDF, then printed a couple of images to 4x6 photo paper from the cassette tray. Looks like the MP500 driver works just great! Cool!

Double-clicking to select text fails in jEdit on Kubuntu Gutsy Gibbon (7.10)

After a failed attempt to upgrade Feisty, I wiped my Kubuntu partition and reinstalled Gutsy from scratch on my Compaq Presario C506ca. All went well - I managed to get the sound working (can't recall the tweak right now), got Ruby, Rails 2.0 and jEdit installed. Then I discovered I had to double-click real fast to select words or lines of text in jEdit. A little googling around led me at last to this post Bug #55270 in xorg (Ubuntu): “Double-click timeout is not applied to X”, which explained the problem and best of all had a fix: add *multiClickTime: 400 to your .Xdefaults or .Xresources file (not sure which one applies to which environment, but .Xdefaults worked for me).
