Adobe Coldfusion MX on Ubuntu Server

Ever since I went 'Apple', the urge of moving away from Microsoft Windows operating systems is getting bigger and bigger. A couple of weeks ago I installed a two Ubuntu servers (v7.x) at work. Mainly for testing , and educational purposes.
The installation went extremely smooth on old Compaq ML370 server hardware. So, as a test I tried to install Adobe Coldfusion MX (Coldfusion 8 ) on the Ubuntu server (with Apache, and MySQL).

There are several postings on the Internet suggesting that it should be possible. Even though Ubuntu isn't on the supported platforms list for Adobe Coldfusion MX.

NYC in Prime

NYC TimeSquareIn a couple of weeks I'm off to New York for a couple of days. This time I'm packing a DSLR instead of the old Canon IXUS V. And to save my back (and neck), I'm not taking any of the regular zoom lenses with me. It's just gonna be me and a couple of prime lenses. These lenses aren't as flexible as a zoom lens, but they weigh a lot less Three primes approx. equals 1 nice zoom lens (nearly 2 pounds), but you mount only 1 lens at a time on the camera.

Currently I've got a 35mm f/2D and a 50mm f/1.8D prime for my D300. The lack of zoom capabilities will force me to be a little more creative while strolling the streets of NYC.

It would be nice to have a 24mm f/2.8 (or 20mm f/2.8) as well for a little more wide angle. Downside is that those are relatively pricey, or not available. the biggest photo/video store in NYC sell those at low prices, but they're out of stock.....

UPDATE: first images of the Nikon 35mm f/2D looks promising. The lens is a bit larger than the 50mm f/1.8, but image quality looks better (contrast, colors).

Ubuntu 'Hardy Heron' Released

As of yesterday, the latest Ubuntu release 'Hardy Heron' is available for download (both client and server). Every time a major Linux distri(bution) hits 'the shelves', the Linux community roars. With each release (Ubuntu or whatever flavor) the Linux community gets closer, and closer to Windows.

Even though the OS itself is getting better and better. It still lacks the support of decent major software like Adobe Creative Suite, etc. It's missing the software people use in every day (business)life.
Sure, there a million different ways of running Microsoft Office or Adobe Photoshop on a Linux OS, but these require a commercial piece of software (CrossOver) , or in depth knowledge of the OS to make it work (Wine in some cases). Two things that shouldn't be required. Not if you're used to Windows (or Apple's OSX). And even if you find a 'substitute' it's most likely to have an awful user experience.

The average housewife won't use Linux, because her friends all use Windows. All those nice little Windows programs, which makes life easier (or a living hell with all the mal/spyware out there). So if the Linux community wants to make a difference they need to create some sort of critical mass (by their selves, or by Microsoft screwing up) to get the attention of the 'normal' user. But in a community where there's no real (commercial) business model, it's gonna be damn hard.

Microsoft created this critical mass by playing (probably) the best marketing trick in the world; Release Windows 95, and turn a blind eye to those who use a pirated copy at home. The home users create demand on the workfloor, so businesses start to use it on their workstations. Soon everyone was addicted. And now it's damn hard to beat the addiction.

B.t.w., Apple is doing it a lot better. They created a nice and stable OS (just like the average Linux desktop distribution), BUT the OS has ALL the relevant drivers for the hardware used. ALSO they have a complete (and cheap) software suite (iLife and iWork), which is more than enough for the average family. No need to search the caverns of the Internet for software, and they look and feel the same as the OS.

So, I guess that my conclusion is that the OS is nearing perfection, but it (Linux in general) lacks good and decent third party software (and a good marketing machine :) )

In the mean time; I'm gonna upgrade my Linux (mail, web, and ssh) servers at work to 'Hardy Heron'.

Zoo's

MeerkatLast weekend I visited Ouwehands Dierenpark. A Zoo near the town of Rhenen in the Netherlands.

It had been a while since my last visit to any zoo. It sure is nice to stroll around the zoo with a camera, but in many cases it almost seems cruel to see those animals in those cramped spaces for the rest of their lives.

I think it might have to do something with seeing all those animals in the wild in Africa. Once you've seen that, the rest is kinda sorry, but on the other hand, not everyone has the possibility of going to Africa, and this might be the only way of seeing those animals in real life......

B.t.w. those cute polar bears are known to chase humans. Especially photographers :)

All Comments Held For Moderation....

Ever since I upgraded to Wordpress 2.5 I had to moderate every comment posted on this blog. Note that I hadn't turned this on in the Wordpress settings.

Some research showed that it might have to do something with 'older' plugins. After a trail and error period I found out that the WP Hashcash plugin was to blame. Ever since I de-activated it, the problem seems to be gone.

VMWare and Firewall / VPN Clients

Well, that was another morning well spent....

A couple off weeks ago I started experimenting with FreeRADIUS on Ubuntu server (v6.06.2 TLS). Mainly because I needed to test some things for work. So I used VMWare to experiment. The networking part was set-up as Bridged.

Today, I wanted to test with iperf (a tool for network performance testing). So I launched the virtual machine, but there was no network connectivity. ifconfig showed that eth1 didn't received an IP adres.
So I ran every possible test there was;

  • restarted the interfaces (/etc/init.d/networking restart)

This resulted in the following;

Listening on LPF/eth1/00:0c:29:68:e3:eb
Sending on LPF/eth1/00:0c:29:68:e3:eb
Sending on Socket/fallback
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 12

The "DHCPDISCOVER" messages continue about 4 times, then the message:

No DHCPOFFERS received.
No working leases in persistent database - sleeping.

  • restarted the DHCP server
  • rebooted the virtual machine
  • changes the networking to NAT instead of Bridged (this way, connectivity was restored, but not the way I wanted. I needed Bridge-mode)
  • Tried to run the virtual machine on OSX (VMWare Fusion), which worked surprisingly.

After this I ran Wireshark on my server to see if DHCP request were coming in.... And you might have guessed; No DHCP request were reaching the DHCP server. So the problem was work PC related.... As a matter of fact, I had the Cisco VPN client running..... Which didn't allow the DHCP request broadcast.

Shutting the VPN client down solved the DHCP problem. After the virtual machine worked I could reinitiate the VPN.

Mental note to myself: do NOT boot/restart the virtual machines when the VPN is up.

Pudong Shanghai Skyline Panorama

I 'found' a couple of 'weird' photo's in my Lightroom collection. It seemed that they were supposed to become a panorama, but I somehow forgot to create it.....

Shanghai Skyline Panorama


It has been a while since my holiday to China and Tibet, but it's better late than never :-).

Authentication Required While Printing on OSX 10.5.2

Since I upgraded from OSX 10.5.1 to 10.5.2 I haven't been able to use my shared printer on on my Windows server. Every job I submit gives me an error saying On Hold (Authentication Required).

There's no way that I could submit the printjob to the server from my Mac.

It seems that there is a bug in the authentication mechanism on OSX 10.5.2. If you add a (network) printer by using the System Preferences, you get to browse to find the actual printer.

Wordpress v2.5 Upgrade

Today, I upgraded to Wordpress 2.5. The upgrade proces was easy as usual. Before the upgrade I checked all the plugins used, and upgraded those first. The new features / layout of the adminpages are great. Also the new editor works like a charm (even on Safari). Somehow it feels a bit more intuitive.

Only downside is that the Wordpress Stats on the dashboard won't work in FireFox. It works fine in Safari. Instead of showing the graph in FireFox it shows the actual dasboard page from wordpress.com.

Nokia E61i Firmware Update - update

It's been a couple of days since my firmware update, so it's time for a small update on the subject.

The biggest advantage is that the mail client is very stable. I use (secure) IMAP and I have 3 mailboxes configured on the device. The mail client hasn't crashed yet.

The biggest downside (in my opinion) is that the 3G connection drops automatically, so you need to re-establish the connection every time. Sure, it saves bandwidth (and costs), but it's annoying that you actively have to monitor your e-mail.

Thankfully, the advantages outweigh the disadvantages, so I'm still happy with the Nokia E61i.
