Leica Rangefinder M10 Rumors
;)
Many of you may have heard, that Leica has scheduled an event for May 10th 2012. These events fuel the speculations of the things that may be announced. One of those things being a new Leica (rangefinder) camera called the M10.
Along with this rumor, everyone has (special) feature wishes / requests that this new camera should have. Some of those (IMO ridiculous) features include:
- Auto focus
- Electronic Viewfinder
- Build-in Flash
- Black and White only sensor
Mozilla's Firefox Invalid, Yet Valid Certificate
In my line of work I get to work with a lot of security devices which run self-signed certificates. Those certificates are most of the time generated when the device / appliance is installed, or configured for the very first time. When you connect to one of those devices with a web browser, you tend to see the warnings displayed by the browser that the connection is not to be trusted.
;)
In Firefox, you can add an exception in the browser. When you've done that, the next time you go to the website, the browsers treats the website as trusted.
Moerputten and Heusden
Last weekend we had our yearly spring trip with the camera club. Somehow the word' spring' didn't come in mind on that day. When I left home, the sun tried to break through, so with luck, it could be a nice day for photography..... Luck was nowhere to be found. The whole day, nothing but drizzle, wind, rain, drizzle, and rain (at least in the vicinity of ' s Hertogenbosch.)
I went a bit early, and when I arrived, I was the only person there, so I was able to shoot some photos without having to worry about other people showing up in my photos.
The Moerputten is an old trainbridge that runs through a patch of protected nature. It's basically just a bridge now. No trains run over it.
The Depressing Belgium Ardennes
Some depressing photos from the Ardennes in Belgium.... And these 'objects' are still being used by people.
A combination of a store/shop, and living quarters:
Small (literally) house in the village of Boulion:
The following photo was shot during a foggy day on the parking lot of a supermarket:
I definitely wouldn't want to live there, but is it nice to make photos some cases :-)
Louwman Car Museum, The Hague
Last weekend, we visited the Louwman Car Museum in the Hague. I really had no idea what to expect of this museum, but I was surprised in a very positive way. The building is new, and filled with cars from the late 1800's till today. Including most (if not all) the classics.
If you're in the vicinity of the Hague, you should visit this museum (even if you're not a petrol-head).
Courier IMAPd and Mail.app warnings
After installing an ISPConfig deployment, everything seemed to work properly, but every now-and-then I got this weird error that there was something wrong with the mail server configuration. The Apple Mail.app showed a exclamation mark with the following message:
The server returned the error: The attempt to read data from the server server.domain.ext failed.
Some research showed that the Apple mail clients tend to open several connections for IMAP, and the default setting of the Courier IMAPd server is to allow (only) 4 connections from the same IP address.
Modifying the Courier config file (/usr/lib/courier-imap/etc/imapd) and allowing e.g. 20 connections from 1 IP address solved this problem.
<ORIGINAL CONFIG>
##NAME: MAXPERIP:0
#
# Maximum number of connections to accept from the same IP address
MAXPERIP=4
<MODIFIED CONFIG>
##NAME: MAXPERIP:0
#
# Maximum number of connections to accept from the same IP address
MAXPERIP=20
If your company / household holds several imap mail clients you may need to increase the counter even more (65536 is the maximum amount of connections for ANY IP address).
If you have SSL enabled on the Courier IMAPd server you also need to add the MAXPERIP variable to the imap-ssl config file (/usr/lib/courier-imap/etc/imapd-ssl).
Finally, you need to restart the Courier IMAPd services (/etc/init.d/courier-imap restart)
Changing SSL Certificates in a ISPConfig v3 Configuration
When you install a Perfect Server based on Centos and ISPConfig v3.x, the system / 'installer' creates for the components self-signed certificates. All these certificates will generate different warnings in your browser, mail clients etc. So time to eliminate those warnings.
First I needed to find out where all those certificates are located, and what there formats are. In my case, there are three services that use SSL/TLS in some form;
- Postfix SMTP service
- Courier IMAP service
- http / Apache2 webservice
Checking the configuration files will reveal their locations.
Getting ISPConfig to Work on Centos
This is not a manual describing the installation (pre-requisites) of ISPConfig software on a Centos platform. An excellent manual can be found online. It's just that I ran into a problem when I tried to connect an e-mail client to the (IMAP) mailserver (controled by ISPConfig). All the appropriate ports / listeners were up and running, so it had to be a configuration issue.
Googling around didn't solve my problem. My collegue, Xander (@xmoments / xmoments.nl), cam eto the rescue with the solution;
yum install cyrus-sasl-plain-2.1.23-13.el6.x86_64
Software that handles cleartext passwords between mail processes. After the installation, the mail went flying across the Interwebs.
Screen Capture Can't Be Saved
After upgrading my iMac to OS X Lion (10.7) everything works (or at least seems to work), until I tried to do a screen capture with the built-in tools.
Things that worked:
- Capturing the entire desktop to file
- Capturing a selection (using the cross-hair) to file
- Capturing the entire desktop to the clipboard
- Capturing a selection (using the cross-hair) to the clipboard
Things that didn't work:
- Capturing entire windows to file or the clipboard (SHIFT-COMMAND-4 + SPACE / SHIFT-COMMAND-3 + SPACE)
All I got was a weird notification box with the message:
Screen capture can't be saved
The console application also showed an error message:
12/16/11 1:40:08.762 com.apple.SystemUIServer.agent: screencapture could not capture window 3c
Lurking around the Interwebs, I found this seem to occur after an upgrade of the OS, but real solutions are hard to come by.
This is what I did to solve my problem:
- Remove the screencapture PLIST (preferences) file (~/Library/Preferences/com.apple.screencapture.plist)
- Copy a com.apple.screencapture.plist file from a working OS X Lion environment and place it in the correct location on the troubled OS X installation.
That seemed to result in two com.apple.screencapture.plist files (one with an additional extension of .locked). I removed the .locked file, rebooted the iMac, and screen capture worked again.
I must mention that I didn't see the .locked file initially. Could be that it existed before. In which case I probably did more than was required to get things fixed....
