Are Netbooks really dead?

20111129-012931.jpg

Acer is sticking by netbooks.
Samsung is not.
So who’s making a mistake? Did tablets kill the netbook?

Tablets are certainly on fire right now. Not tablets per se, the iPad that is.
Kids want tablets and parents agree, as they are spreading light wildfire in the enterprise. It seems like Steve Jobs managed to invent an entirely new computing and entertainment category based on early failures of others. Again.

While you can attach keyboards and stands to tablets, seed entire accessory ecosystems, tablets remain content consumption tools. The can attach themselves to other devices as controllers and rich user interfaces – a future I am truly stoked about. But writing serious documents, creating stuff – they are not ideal. To create, a keyboard, a real keyboard, seems to still be a necessity.

Why keep HTML5 open when you can make it proprietary?

Say what you will, this is pretty cool – at least at the idea level: a specialized, HTML5 web browser for mobile devices that provides special hooks for HTML5 apps granting them access to native device features. Pretty nifty, right? Naturally the people who control the platform, kinda get to decide what can and cannot run, maybe get a cut of the action for the business that they are generating for you and for the work that they invested in making and marketing the app.

In exchange for openness, you get cool features (especially for games) and capabilities you otherwise will not be able to provide. Tradeoffs tradeoffs. Still, pretty darn cool.

mobiUs … the world’s first HTML5 Web App browser.

Xcode: “No match for certificate/private key” error and resolution

An app we were building for the iPad was recently approved by the client. Being a more capable organization, the client wanted us to build the app for them using their Apple developer and app store credentials for submission. To do that they sent us the three necessary files:

  • Public Key (Distribution)
  • Private Key (Distribution)
  • Mobile Provisioning Profile (Distribution > AppStore)

I also modified the app's bundle identifier to reflect the identifier specified by the client.

I merrily added the keys and certificate to the OS X key chain. Yet Xcode was unable to build using these updated credentials. The error that was reported was:
"Profile does not match any valid certificate/private key pair in the default keychain"

After digging around I pinged my friend Glenn Martin from Intrepid Development to see if he knew what was wrong. Glenn actually knew what went wrong: apparently OS X 10.6.8 imports keys to the System key chain instead of the Login key chain. Xcode only looks at the Login key chain. All the was necessary to fix the issue was to drag and drop the key in the Keychain Access application from the System key chain to the Login one. Mindless fix to a truly frustrating problem.

Hope it helps you.
