Vanishing HD Space on Popcorn Hour

Sometimes you think you're mind is playing tricks on you. I have that sometimes. E.g. I have a Popcorn Hour  (Networked Media Tank) which holds movies and series I watch. Bits and Bytes come and go on that machine. Thing you've seen are deleted, and replaced by new content. But over the 'years' it seemed to hold less and less content. Oke, movies have increased in size (10-20GB per movie is nothing nowadays). So I didn't really think much of it....

Until I started transporting the content with Transmit instead of FileZilla. Transmit was configured to show even the hidden files, and hidden files it showed. I found 4 hidden temporary pureftp-upload files of almost 32GB each. The timestamps on those files differed from late last year to a couple of months back

.pureftpd-upload-<some random string>

The problem was that I couldn't remove them from the Popcorn, but I really wanted my 120GD of free space back. Turned out that the FTP daemon on the Popcorn was locking these files. Reboot of the popcorn didn't help.

The way to remove them was to stop the FTP daemon on the Popcorn in the menu, and access the device through SMB (or another protocol you can use), and make sure that you can see hidden files.
Select the files and press delete, and they should be gone. After that you can re-enable the FTP service if you like.

Getting Around a Wide-Angle Lens

Going on holiday is fun, but it's also a time of concessions on several levels. Especially if you can't bring every lens you own or (in theory) might need. Since the awesome Nikon 5-500mm f/1.8G VR ED N (small, <€1000, <1kg) isn't widely available. This means deciding what to bring in your camera bag.

In my case, I wanted to experiment with primes during my holiday. this also means that you have to use the foot-zoom, and on several occasions that won't work because of certain limitation (walls, buildings, ravines, etc.). In those cases you have 3 options;

1. Don't make the photo
2. Make a photo, but know immediately that it will end in /dev/null when you get home (a just-for-the-record photo).
3. Improvise

So as you might have guessed, I ran into such a situation in Toledo, Spain. They have this great cathedral in the middle of an old town with narrow streets. You need a ultra-wide angle lens for almost anything there.

Splunk> Making Sense of Logfiles

My area of expertise in the professional world is Network Security. This includes protecting network from intrusions, but also delivering reports about the network status. For the latter we use SIEM(like) environments like the Cisco CS-MARS and the Juniper STRM.
The 'problem' with these devices is that they are great in reporting incidents and creating awesome reports about everything, but they lack the functionality to do some serious investigating.

I have several customers with a SIEM, and most of them still use (Linux) commandline tools like awk, grep, etc. these tools work, but you need to scrape everything together yourself, and building queries can be quite challenging. This is where Splunk> comes in.

Installing Adobe Coldfusion 9 on OSX Server 10.6.4

Updated on Tuesday, July 20, 2010 at 11:08 by Willem

Updated on Friday, July 30, 2010 at 7:53 by Willem

After Apple updated the Mac mini to it's current form (mid 2010), I decided that it was time to start replacing my 'faithful' Windows 2003 server with something a bit less power consuming. The original Mac Mini was basically a consumer device, but a while back, Apple released a server version of the device. The main differences are:

• Only 1 CPU model available (2.66GHz at this moment)
• No DVD drive
• 2 * 500GB internal disks
• OSX 10.6.4 Server edition (unlimited clients)

Basically everything you could ever need for a server with a very small footprint.

The installation of Coldfusion is not straight forward. Not that I expected it to be [1], [2], [3], but one keeps hoping on an installer that actually installs the complete package, and where you don't have to edit files yourself to get it to work. It's not that it's the very first version of the scripting engine......

Anyway, the installer guides you through everything needed to INSTALL the software. Getting it to work comes next....

Adobe Photoshop Lightroom 3 Released

Adobe released Adobe Photoshop Lightroom 3 into the wild. The application can be downloaded from the Adobe website. The trail can be upgraded to a fully functioning version when you enter a valid serial number.

New features are;

• Flickr integration
  Really nice feature. I do wonder how (and if) it works across multiple computers.
• Easy sharing
• Lens correction
• Support for DSLR video's
• Image watermarking
• Tethered shooting
  For Nikon and Canon Cameras
• etc.

After I downloaded the new version I installed it on my MacBook. The 'old' Lightroom v2.x can be used besides the new version.

Droplets in Photoshop CS5

Every photo I upload to Flickr goes through a watermarking process. To do this, I created a watermarking action within Photoshop (started this in the CS3 days). These actions can be 'converted' to so-called droplets. These are 'shortcuts' you can place on e.g. your desktop. Every image you drag onto this droplet gets opened in Photoshop and the preconfigured actions are applied.

This worked in Photoshop CS3, and CS4 (after some modifications to the original action). But in Photoshop CS5 the droplets won't execute. The action itself runs smoothly within Photoshop, but when you export it as a droplet, the action won't start. You have to start the action manually.....

I even tried to create an action / droplet from scratch in Photoshop CS5, but that one won't run either when I drop a JPEG on the droplet. This is a reason for not upgrading to CS5 on my main machine (which also still runs Leopard for compatibility reasons).

According to the online Adobe Photoshop CS5 helpfiles regarding droplets, the droplets should still function. So I write this of as a bug in the initial release of Photoshop CS5.

Update on Friday, May 7, 2010 at 6:51 by Willem

I posted a bug report @ Adobe after I found out that I'm not the only one having issues with this.

Update on Wednesday, May 26, 2010 at 19:44 by Willem

The discussion on the Adobe Forums have attracted the attention of Adobe employees. So hopefully, we'll see a bugfix soon. I don't want to modify every action I have a droplet for. Especially since I use several actions made by others, which I 'converted' into droplets.

Update on Thursday, July 1, 2010 at 8:05 by Willem

Adobe released an update for Photoshop CS5 (v12.0.1), which fixes the droplet problem in the 32bit mode (I haven't tried the 64bit mode yet). Just launch the Adobe updater and the update will be installed.

And now; continue to evaluate the new features of Adobe CS5, and hope I don't run into more annoying bugs.

HDR Processing in Adobe Photoshop CS5

The new CS5 edition of Adobe Photoshop has refined the HDR (High Dynamic Range) processing. Now, you won't need the Photomatix plugin (in theory).

After selecting the 'Merge To HDR in Photoshop' option in Lightroom, the images get exported to Photoshop and it starts doing its magic. Normally (in the earlier versions) you would end up with a 32-bit image, but now you have the option of manipulating the 8 or 16-bit version of the image. Just like in Photomatix.

Photoshop CS5 HDR interfaceInitial experiences are not really positive, but that can be related to my experiences with Photomatix. A quick glance at the controls available, it should be able to produce similar results.
Talking of Photomatix; The plugin used in CS4 won't work in CS5. You need to download the CS5 version of the plugin at the HDRSoft.com website (Mac / Windows). The new version is universal (32 and 64-bit), free of charge to registered users, and works only in CS5.

One thing I didn't expect was that Photoshop started downloading a lens database from the Adobe website during the creation of the HDR. No idea if this is used in the HDR creation, or that this is done only once and used in other Photoshop CS5 plugins / filters

First Contact With Adobe Photoshop CS5

As most of you will know, Adobe release its latest Creative Suite (CS5) a couple of days ago. Personally, I only use Photoshop and Dreamweaver. For the casual photographer, the CS2 or CS3 version of Photoshop is probably more than you ever need. So are there reasons for upgrading (or reinstalling)?

First, Adobe doesn't really support the older versions of Photoshop anymore, or the operating system you run at this moment has some issues with an older version. So an upgrade will happen sooner or later. But apart from compatibility issues with the OS, there are some new features available for the (casual) photographer. The following features are the ones I'm most interested in;

• Easier ways of doing complex selections
  Basically a tedious job in every earlier version, so I have my reservations on this feature.
• Content Aware Fill
  Create-photos-in-Photoshop-instead-of-by-using-a-camera feature.
• HDR Imaging
  Let's see if it beats Photomatix Pro.
• Automatic Lens Correction
  I now use PTLens on the photos that need the correction.
• 64bit support (!!!!)
  A feature that's long overdue.
• Better Black and White conversion
  I mostly use Nik Silver Efex Pro at the moment.

In this post I'll be evaluating Photoshop CS5 on some of the points I mentioned above. Others will become a separate blogpost later on. For the moment, I'll be starting with 'upgrading' from CS4 to CS5, and see if that goes well (after I've cloned my MacBook disk with SuperDuper! to make sure I can always go back if things go sour).

Another thing that I need to check out is compatibility with earlier versions of Action scripts, and (older) plugins. Just check the CS5 or Photoshop tag for all the related posts about Photoshop CS5.

SafeSign and Apple OSX Snow Leopard

Last week I got an e-mail from one of the product managers @ AET Europe regarding the availability of SafeSign / Tokenlounge for OSX Snow Leopard.

The content of the e-mail wasn't very encouraging.... It seems that the Snow Leopard of SafeSign / Tokenlounge release is delayed by a bug in the Apple Keychain;

---------
We use systemkeychain -T to create a login keychain (for a new FV user) associated with our token. When trying to unlock this newly created keychain during login with the smartcard, we get prompted with the "unable to unlock login keychain" panel - as you have observed -.
This is basically our main concern, as this was perfectly running under 10.5. Any idea why the system wants to update the login keychain password, prompting the user with that panel???

What we have discovered beside, is that when you click Create New Keychain on that panel, the keychain gets encrypted with the PIN of the smartcard instead of the RSA key, which is a major security issue (Same behavior if you click Update Keychain Password)...
You can easily verify this last issue by removing your smartcard, launching Keychain Access and entering your PIN code to unlock the keychain...

Once again, we didn't have this kind of problems with Leopard.

As long as this issue isn't resolved, there will be no version for Snow Leopard. The (security) risk is just too big.
-------------

So, we need to be patient, and wait till Apple solves this. In the mean time, when you need the SafeSign software for your every day work, you shouldn't upgrade to Snow Leopard.

Check the follow-up on the original SafeSign post for the availability on the Leopard version of SafeSign / Tokenlounge.

Free Lonely Planet City Guides for iPhone

Not being able to fly has its advantages. In response to the widespread chaos caused by the eruption of Iceland’s Eyjafjallajokull volcano (pronounced as 'whatever'), Lonely Planet is offering 13 of its European iPhone guides for free (as in 'free beer').
