Configuring Syslog-ng on Ubuntu
Syslog-ng is a replacement for the default syslog daemons you get with most Linux distributions. The advantage of syslog-ng is that the configuration is easier to understand, and it gives the sys-admin numerous advantages. Especially in complex environments.
Let's say we have a RADIUS environment which is able to send authentication and accounting information through syslog to external devices. And let's assume that a relevant part of this syslog information is needed by a department within a large cooperation.
Installing syslog-ng (on Ubuntu) is done by the following command:
# sudo apt-get install syslog-ng
Through the use of syslog-ng we can store, and/or forward syslog information based on the following (but not limited to):
- source IP address
- destination IP address
- syslog level
- content in the original syslog message by using regular expressions.
All this can be configured in the /etc/syslog-ng/syslog-ng.conf file.
Moving from Flickr to SmugMug
Over the last couple of years, I've been storing my photos online @ Flickr. But I fear that time has come to move forward. Forward to another service for the next couple of years. The main reason for moving is that Flickr doesn't seem to innovate. No innovation basically means going backwards, in these days.
Flickr is a WYSIWYG environment. What you see is what you get, and not in the way this term is usually used on the Interwebs. There's no way of changing the coloring or appearance (white only). No way of integrating into another website (e.g. changing the URL).
Unable to Upgrade Firefox on OS X
Today I tried to upgrade Firefox 5.0.1 on my iMac to version Firefox 6, but it failed with some 'weird' error;
The operation can't be completed because the item libsmime3.dylib" is in use.
Weird because I didn't have FireFox running at the time. Removing Firefox didn't work either, since I couldn't remove it from the Trash (same error).
Turned out that I had the Cisco AnyConnect VPN installed on my system (process name: vpnagentd). To 'unload' this process enter the following in Terminal:
sudo launchctl unload /Library/LaunchDaemons/com.cisco.anyconnect.vpnagentd.plist
Install Firefox, and enable the vpnagent again by entering the following in Terminal:
sudo launchctl load /Library/LaunchDaemons/com.cisco.anyconnect.vpnagentd.plist
And all should be well.
Leica M9-P review by a dSLR User
A nice (impression) review of the M9 by someone (Darren Rowse) who uses a dSLR in real life.
Burn OS X Lion Installation Package to DVD
The moment you download OS X Lion, you'd better have a copy of OS X Snow Leopard, because by default the new Apple OS can only be installed on a previous installed Operating System (upgrade). So if you need to reinstall your Mac in the future, you need to install OS X Snow Leopard first, and then upgrade to OS X Lion. Also, there's no way of ordering an OS X Lion copy on DVD..... Well, that sucks.
Fortunately, there's a way of creating the installation DVD by extracting the actual disk image from the downloaded OS X Lion installation package.
Just Won a Panasonic Lumix DMC-G3

The title says it all. Nuff said.
I entered a photocontest a couple of weeks ago @ fotowedstrijd.nl, and totally forgot about it... until today. I received a phonecall from the organizer stating that I had won. At the time I had no idea with which photo (I had to ask....).
Manipulating EXIF Info
The Leica M9 has no means of determining foreign or old lenses. The newer Leica lenses have a 6-bit (visual) coding mechanism for determining the lens. Problem is that this is only for (relatively new) Leica lenses. There is the possibility to manually select the lens in the menu of the M9, but that's only limited to the Leica brand lenses. No option for Carl Zeiss lenses.
For certain characteristics, and in-camera processing of the RAW image it's handy to manually select a Leica lens even though you've attached a Zeiss lens. This can be automated by coding the lenses yourself (or have Zeiss do it for €100 a lens).
All this is nice, but it still generates photos with faulty EXIF information, because you shot the photo with a CZ C-Sonnar 1.5/50mm and not with a Leica 1.4/50mm Summilux ASPH....
Leica Blog
After I acquired a Leica M9 with peripheral equipment, I decided to document my M9 learning experiences on a seperate blog on my website. I don't know if I'll keep it like this. I might move the content to this blog. Don't know yet. Time will tell.
Anyway, in the mean time I've added some content to the new Leica blog. Check it out. I hope you'll find it usefull.
