iPad Wifi Update

Just changed the setting on my Airport Extreme. (I changed it with a laptop, not the iPad. I don’t know if there is an app for that yet.)

It was set to be 5GHz only, but it was also 802.11N only as well. I changed it to allow 802.11A compatibility and turned off wide channels.

The range is now improved. I’m typing this in a room that was out of range yesterday.

iWork on iPad: Keynote

I understand that someone on the internet has compiled a considerable number of issues for iWork on iPad.

For me, I’ve noticed that Keynote will not loop a playing slideshow. (A good feature if, for example, you had a little file that would talk about services your company provides while you do something else.)

Workaround: export the completed slides to image files. Put them into an iPhoto album and have the iPad play that album as a slideshow. It’s not as fancy, but it will play in a loop until you stop it. And if you make it the one album for locked mode, you can play it without leaving the iPad unlocked.

Working with iWork on iPad and Mac

In playing with the iPad’s Office products, I’ve started trying to my existing presentations and Pages files to it.

My first attempts resulted in messages indicating that I needed iWork 09 (I was using 08.)  I went out to my local Best Buy and bought a family pack (just $20 more, and I’m somehow sure my wife will want to use it with her iPad/laptop too.)

XCode Problem “expected specifier-qualifier-list before

Solution:  check that you included appropriate frameworks in your project and target.

I had this just now while building a new project and forgot to put the frameworks into the project.

Connecting Samsung Blue-Ray to Internet Wirelessly

I have a Samsung Blue-Ray player that my wife gave me for Christmas in 2009.  Every since, my family has been asking (pestering) me to connect it to the internet so they can watch NetFlix downloads on it.

We’ve gone to electronics stores a few times to buy the Samsung-specific WiFi adapter for it (LinkStick I think), but they were always out of stock.  When I did find one,  I balked at the $79 price tag.  (That was mail-order on the internet in April 2010.)

A few days ago,  I got the blue-ray player onto the internet and probably would have made Alton Brown proud (the start of “Good Eats” who always talks up multi-tasking appliances.)   I bought an Apple Airport Express for $99 (just $20 more than LinkStick)  and installed it behind the entertainment center.   (Not to be confused with an Airport Extreme base-station or other airport device.)

I connected it to my laptop with an ethernet cable and set it up as bridge the house WiFi, then connected it to the blue-ray player with the same ethernet cable.  I checked the setup on the player for networking and voila!  It was on the internet and we began the NetFlix setup.

This is cool to me for a few reasons:

  • I didn’t have to buy hardware that might have only worked on Samsung’s player.
  • I can attach the Airport to my stereo and send music through it.
  • I could decide to attach a USB printer to it, sharing it on the network. (Not likely in the living room.)
  • I could get this device to connect to my 5GHz WiFi hub  (the b/g space on the normal 2.4 GHz WiFi is pretty crowded in my neighborhood.)
  • If I lose the player for some reason, I can re-use the airport for other things.

XCode Giving Incorrect Error Messages after Upgrade to 3.2.2

A few days ago,  I was helping upgrade a Mac’s XCode environment from 3.1.4.   After the upgrade, the first attempt to build and run a project resulted in strange errors.  “Security Policy Violation”  came back from the device along with problems with the entitlements.

After much poking and prodding, I noticed that the Base SDK for the project was set to “iPhone OS 2.0 (missing)”.  The base SDK for the project was no longer available in XCode after the 3.2.2 upgrade.

Resetting the BaseSDK to 3.0 solved the issues and the build and run was fine.

iPhone Pattern: The ID Device?

I’ve seen stories lately that make me think another app pattern is emerging: iPhone as an ID. (Not news to you? Gotta love intelligent readers.)

It does make some sense.  In cases where serious identification is not crucial, the iPhone can be used.  With a full iPhone, you can bet people don’t just loan them out to people indiscriminately.   On days when I’ve forgotten my wallet, I still didn’t forget my iPhone.

Think about these:

  • Companies are sending account information, such as passwords or password reset info to the mobile phone recorded in the account.
  • RSA has a “SecurID” app for the iPhone.  Its used just like the cards and keychain dongles that give a code number once a minute.  That’s 2-factor authorization.
  • iPhone and iPhone apps are being used to pay for physical goods and services. A hotel reportedly issues iPod Touches to guests.  The guests uses them to order food and drinks by the pool and pay on the room account.  (They give the devices back at checkout time.)
  • Apps are used to exchange contact information.

Can’t Add User Account to OS X Server

Recently had a request for help from a client who could not add a new user to their Open Directory.  I Googled around for a while before finding an answer that was easier than rebuilding all of Open Directory and its accounts.

Error: eDSRecordNotFound

Solution:  Get Open Directory to restart by turning the SSL option on, then off again.

After this, the user could be added normally.  The error did not occur.
