Apple CEO Steve Jobs presents the iPad on January 27th 2010 (Picture: Apple)

Finally Apple officially published the video-on-demand of the Apple special event “Come and see our latest creation”. Apple CEO Steve Jobs unveiled the iPad at the Yerba Buena Center for the Arts Theater in San Francisco on January 27th 2010. You can watch it as a QuickTime video stream or as MPEG-4 … and it’s really worth it :-)

This is the day: Apple will start their press event at the Yerba Buena Center for the Arts Theater in San Francisco. At 10:00 am PST or 07:00 pm MEZ.

Like the legendary Steve Jobs Keynotes in the past, it is quite a tradition that some journalists blog live from the event … so Apple fans all over the planet can take part on the press conference. Here are the most important liveblogs:

As soon as the videorecording of the event is online as a Quicktime videostream … there’ll be an update ;-)

Apple invited the press to their “Come see our latest creation” event in San Francisco on January 27th. And the computer and e-book industry starts trembling with fear: Companies like Microsoft and Amazon are getting really nervous, because Apple may conquer the emerging market of Active Content.

Apple did not announce that the company will be engaged in the e-book or tablet-market – but the rumors about an “iSlate” or “iPad” are quite persistent. Therefore Microsoft’s Steve Ballmer tried to steal Apple the show at his keynote at the CES in Las Vegas: He just renamed the tablet-PCs on stage as “slate-PCs” … but it’s not about a name.

Now Amazon announced, that the company will open up their e-book platform for third party developers: Within some month, they’ll release a Kindle Development Kit (KDK) and will also provide the sales channel for the active content created with that software development kit (SDK).
The revenue sharing model looks quite familiar to iPhone developers: 70% to the developer and content provider, 30% for Amazon. But Amazon charges an additional $0.15 per MB for content delivery … as the Kindle is not sold with a mobile phone contract. Amazon has to pay the distribution costs to the mobile network operators if the content is delivered via the mobile data channel.

Amazon is probably in a better starting position in the battle for market shares in the emerging market of Active Content: They have a lot of experience with content distribution with the Kindle and they are in direct contact with the publishers … but Apple has the ability to rouse the e-book-market from slumber by innovation. They may transfer the pathetic e-books into a new and emerging market: Active Content.

There are a lot of advantages for Apple to tip the scales:

  • big and growing iPhone SDK developer community … Amazon has to build up a comparable dev community around the KDK
  • well-engineered and sophisticated iPhone SDK … with a full bandwidth of network-, graphic-, data- and sensor-support
  • color instead of grayscale screens and computing and graphic power
  • touchscreen with gestures
  • amazing design
  • … and there are probably some innovations we don’t expect ;-)

Amazon’s move to open up the Kindle to 3rd party developers and create a platform for Active Content is absolutely right … but can it compete with Apples offering? On January 27th 2010 we’ll know much, much more.

Some days ago I published a first solution for reactivating printing on OKI-printers from Mac OS X 10.6 Snow Leopard … some of you managed it to reactivate the printer by following the instructions – others are still coping with that problem. Also I was disappointed to see that the solution broke again and I wasn’t able to print from Snow Leopard again. That was really annoying – so I spent some time again to find a proper solution. Here it is: Version 2 of how to solve the problem … and as always: no guarantee and on your own risk:

Problem: After updating from Mac OS X 10.5 Leopard to OSX 10.6 Snow Leopard the installed printer driver for the OKI-postscript driver does not work anymore. Here it’s an OKI MFP C5540 … but it should also work with other models, like the OKI C5450 or C8800. The printer diver was installed under Leopard and worked quite well. After finishing the update to 10.6 you are able to send a print job to the printer, but an error message shows up in the print queue.

Diagnosis: Two bugs may cause the problem: Some of the OKI-printer drivers just disregard case sensitivity in their path names – this wasn’t a problem in former Mac OS X versions – but it is a problem in Snow Leopard. The other bug – which even leads to a malfunction if the path names are right – is some wrong file permissions. And this causes Snow Leopard to hiccup when you try to print on an OKI-Printer.

Solution: The easiest way to solve the problems and get rid of the bugs is following three major steps:

  1. Delete the old OKI printer drivers under the folder “/Library/Printers/” … if there are any.
  2. Install a new OKI driver. This will also create the folder “/Library/Printers/OKIDATA”. Then install the specific printer driver for your OKI-printer (especially the PPD file).
  3. Repair the file permissions.

You only need the OKI printer drivers and you have to put in some Terminal commands. But let’s do it step by step:

  • Log into your Mac as an administrator.
  • Step 1: Delete the old OKI files and folders:
  • Don’t forget to backup your data before you start!
  • Navigate to the following folder in the Finder and delete the folder “OKIDATA” or “Okidata” – if there is any.
     Macintosh HD/Library/Printers/
  • Within the folder “PPDs” you may find also some OKI files – at my Mac it was “Oki C5540.ppd” – delete also these files.
  • Step 2: Re-installation of the OKI printer driver. The installation program of older printer drivers may cause problems when creating the “OKIDATA” folder: They may name this folder “Okidata” and put in an old OKfilterA-file.
  • Therefore you should download and install the printer driver for C5550n-MFP of OKI-USA specifically for Leopard users first. Just click on the “Mac OS X.5″ link on the printer driver page of OKIDATA-USA, download the installer.
  • Then start the installer and put in your password. The installation program will create the folder “OKIDATA” as needed.
  • If the C5550n MFP is not the OKI printer you have, you have to download install also the specific printer driver for your OKI-printer model. I had to choose the C5540n MFP. The installation will not overwrite the folder OKIDATA and only put’s the missing PPDs into the right folders.
  • Step 3: Repair folder & file permissions. Open the program “Terminal” – you’ll find it under “Programs/Utilities”.
  • Input the following command into the appearing command-line window and finish it with pressing the return-key:
     sudo chown -R root:admin /Library/Printers/OKIDATA
  • Now, you’ll be prompted for your password … so put in your password of the admin account and finish the input by pressing the return key again
  • Input a second command into the command-line window and finish it with pressing the return-key:
     sudo chmod 775 /Library/Printers/OKIDATA/Filters/OKfilterA
  • A little complicated – but it works. Just exit the Terminal program and restart your Mac. Then you can setup your OKI-printer and select the specific OKI-printer driver manually.

Printer drivers under Mac OS 10.6 Snow Leopard are still sometimes causing trouble. After explaining how to reactivate an OKI-printer – here is the solution for an Kyocera-Mita-printer … and as always: no guarantee and on your own risk:

Problem: After updating from Mac OS X 10.5 Leopard to OSX 10.6 Snow Leopard the installed printer driver for the Kyocera-postscript driver does not work anymore. Here it’s an Kyocera Mita FS-2000D … but it should also work with other models. The printer diver was installed under Leopard and worked quite well. After finishing the update to 10.6 you are able to send a print job to the printer, but an error message shows up in the print queue.

Diagnosis:There are incorrect file permissions under Snow Leopard fort he Kyocera printer driver … and this causes some trouble. BTW a warm thank you to @kappuchino for his diagnosis and solution!

Solution:There is nothing like fixing the bug yourself ;-) You can easily fix the problem by one command in the Terminal:

  1. Log into your Mac as an administrator.
  2. Open the program “Terminal” – you’ll find it under “Programs/Utilities”.
  3. Input the following command into the appearing command-line window and finish it with pressing the return-key:
    sudo chown root:wheel /usr/libexec/cups/filter/kyofilter
  4. Now, you’ll be prompted for your password … so put in your password of the admin account and finish the input by pressing the return key again
  5. That’s it. Just Close the Terminal program. Now printing on the Kyocera printer should be work like a charm.
