Moving The Camera

while taking a photo will create (in general) photos that most people will throw away the instant they see it. You can however exaggerate the moving part on purpose, and create some nice abstract photos (as shown below).

Note that you need to adjust the amount and direction of motion to the circumstances. Another important part is the shutter time in relation to how fast your moving / tilting the camera. This must be long enough to create the blurring part.

Just try it.

Filter / Block IP Addresses On A Juniper SRX

While exploring the configuration options on the Juniper SRX firewall, I stumbled upon the so-called firewall filters. These filters are not to be mistaken for the firewall policy rules. They are something different, but can be used for achieving similar goals.

In my case, I wanted to see if it was possible to quickly block a list of IP addresses (or subnets) without the hassle of creating addressbook entries (Address Sets). My list of IP addresses consists of known hosts that participate in the criminal ZeuS network. These IP addresses are either Command&Control servers or servers used to transfer (captured) data to. In any case, servers you don't want to communicate with.

The solution on the SRX is to create a firewall filter containing the list with hosts / networks. The filter, in my case, is applied to the outgoing interface (fe-0/0/0).

Adobe Creative Suite 2 For Free

Looks like Adobe is giving away the (old) Creative Suite 2 for both Windows and Mac. The CS2 download page contains direct links to all the CS2 products (individual products and the entire Creative Suite 2 installer) AND their license keys.

Product License Key
Photoshop CS2 [Mac] 1045-0410-5403-3188-5429-0639
Photoshop CS2 [Win] 1045-1412-5685-1654-6343-1431

So if you would like to experiment with Photoshop (legally), but don't want to pay a premium price, this is one way of doing it.

There are some caveats you need to consider:

  • The system requirements; The CS2 suite for the Mac doesn't run the Intel CPU, so you need a PowerPC based Mac, OR you need Rosetta. And the latter is no longer available for OSX (Mountain) Lion. I do not know if CS2 will run on Windows Vista, 7 or 8. But you can always run the software in a virtual machine.
  • CS2 has a limited Adobe Camera Raw (ACR) converter. Which means that it won't be able to open RAW files from newer camera's. As a workaround you can first convert your RAW files with the Adobe DNG Converter [Windows | Mac], and open those files with Adobe Photoshop CS2.

Flickr Pro Account for Free...

for 3 months.

During the holiday season of 2012, Flickr offers a free 3 months Pro account. If you should already have a pro account, you get an additional 3 months for free. During these three months you get all the perks a regular Pro accounts has. Meaning unlimited uploads, statistics etc..

Ever since I switched from Flickr to SmugMug last year I let my Flickr Pro account expire, and it reverted to the limited free account. Yesterday I reinstated my Pro status again (for the 3 months). I don't think that I'll be going back to Flickr Pro. When the 3 month offer expires I'll default to the free account. SmugMug offers me much more. Things like dynamic photo albums (bases on keywords / tags), custom domain, layout, etc.. These are all features that Flickr lacks, and that I grew accustomed to.

So why upload a bunch of photos just for these three months? All for the cause of some extra free exposure I guess.

OS X Wireless Connection Problems Solved (??)

Ever since the upgrade to Apple OS X Mountain Lion (10.8) on my MacBook (v5.1) I encountered wireless problems every now and then. These 'experiences' are documented in two different blog posts here and here.
At the time I was also running an 'old' version of Little Snitch (v2.x). After installing v3.0.1 my problems seemed to have solved... Seemed, until I upgraded Little Snitch to v3.0.2.

After the (mandatory) reboot my wireless connections were gone. The adapter wouldn't go active. The symptoms being the exactly the same as before. So I have no doubt, that Little Snitch had something to do with it.

MacBook Wireless Borked Again, Still, etc.

A while back I had regular issues with the wireless adapter on my MacBook after I had upgraded to OSX Mountain Lion, but after the removal of Little Snitch (I still ran the beta version) it seemed that times were a changing... Seemed that is.

This morning I was fiddling about with my photo website, and needed to see the results in several different browsers. One of them being Google Chrome.
Trying to launch the Chrome app, it crashed immediately. Reopening didn't help. So I tried to download a newer version, since I hadn't updated mine since the upgrade to Mountain Lion. The result; It still crashed. Even after removing all Chrome (and Google) references on the disk, it still crashed.

So, it became time to consult the book of knowledge, and see what the Internets had to say about my little ordeal.

Ziggo Internet, Juniper Firewalls and DHCP

At the house I have currently two ISP delivering broadband. Well, broadband isn't the correct word, since the the one of them is only a mere 256kbps (I think). The other is a 'whopping' 20Mbps.
The 20Mb connection is provided by XS4ALL, and the 256kbps is for free (if you have a phone subscription with Ziggo). The 256kbp is the minimum they provide to transport the phone calls, but if you're a masochist you can also browse the internet over that connection.

So, two ISP @ home. Combine that with a Juniper SRX firewall, and a dual ISP setup is born. The theory of that setup is that I connect both ISP's to the firewall, and use the 20Mb line as a default internet connection, but when that one dies, I automatically get switched to the backup line (256kbps).

Unable To Turn On Wireless In OS X Mountain Lion

Last night I was minding my own business on the couch, when the wireless connection on my MacBook (UniBody)  decided to call it a day. According to the symptoms (no bars visible in the WiFi icon in the menu bar, no visible wireless networks in the vicinity), the WiFi adapter was turned off. Turning the WiFi back on was not possible though.

Reset 'Open With' Dialog in Finder

After the upgrade of several programs I found that these programs had multiple entries in the 'Open With' dialog in OS X Finder. The following command (executed in the Terminal app) rebuilds the LaunchService database, and removes the duplicate entries.

Note that the following command is 1 (one) line of code, that you need to copy & past in the terminal window.

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

As far as I can tell, it works on OS X Mountain Lion and every earlier version (at least till 10.6).
