Raspberry Pi Apple Airplay

Posted by on March 23, 2014 No comments

At home I have an audio receiver that has trouble with some of the local FM stations. This is important as I frequently prefer NPR to whatever reality show is on the TV airwaves. I’ve looked at buying digital FM device to get the signal, but that technology never really took off and I couldn’t find anything that wasn’t made for a vehicle. And then it hit me that rather than broadcast, all the audio I want (including podcasts and other non-live audio) is available on a unicast network as well. I just need my audio receiver to connect to the internet.

I followed this tutorial. It is an impressive tutorial in that your grandmother could follow the steps and not get lost. If you’ve used linux before you’ll scroll through a lot of introduction to reach the package names to apt-get.

So now I get my audio: NPR -> Internet -> iPhone (app) -> Raspberry Pi -> HDMI -> Receiver -> speakers. The digital signal is much clearer than the FM I was using.

Note that I’m using HDMI. The analog audio out on the Raspberry Pi isn’t recommended. I’ve tried using it before, and it just isn’t that good. They saved on the design by not including a real analog output but simulating one, which is good for alert noises or some other applications, but for music or even news leaves a lot to be desired. Options include either using HDMI so the digital to analog happens on your TV or receiver that has better electronics or a USB audio output can achieve similar results.

Used Videogames And Why Publishers Make Money

I posted this response on Slashdot to argue against the following reader comment:

…I understand that publishers don’t make any money off used games sales…I get that.

Publishers do make money off used game sales. Not directly, but easy to see if you analyze the system.

Person A buys a game new (ex. $50), plays it, sells it to a used game broker, let’s say GameStop (ex. $20).
Person B buys the used game from GameStop (ex. $40), part of this purchase goes to the broker for facilitating the transaction, part goes to subsidize the original purchase price (the $20 Person A received when selling the game comes from this purchase).

So Person A effectively purchased the game for less money. The lower price for Person A either allows him to purchase the game in the first place (was his perceived utility of the game between $30 and $50?), or leaves leftover money for the purchase of another game (this is his hobby, so more money may end up with game publishers).

So through the secondary market, Persons A and B share the cost. If, as the your hypothetical publisher who doesn’t “make any money off used game sales” argues, Persons A and B would both have bought the game for $50 each, giving them earnings of $100, then the game could have been priced closer to that $100 knowing the secondary market would allow for the cost sharing (let’s say MSRP of $80, giving the broker a $20 piece of the $100 pie). If it wouldn’t have sold for $80 to $100, then both A and B weren’t interested enough to each pay $50, were they?

To put cost sharing another way, my brothers and I would buy a bunch of video games when we were young. The money came from allowance and mowing lawns. To get a $50 game we’d all throw in money and we’d all play the game. If we all had to pay $50 we’d have bought a lot less games, because there wasn’t enough allowance and lawns to mow to get that kind of cash and some games just weren’t worth that much. So is the game studio and publisher losing money? Or are they making even more money? Does it just change the way the industry must operate and market their product?

Here’s the fun question: If cost sharing and a used market didn’t exist, what would the MSRP of a game be? I’d wager less than it is today.

Prefix commands with pseudo

Posted by on December 10, 2009 No comments

So walking to work this morning I figured what the name “otherroute” is about. It’s about going a different way than normal, to be sure, but now there’s more.

The “route” is pronounced like “root”. As in the user root. And since I’m using homophones (some might use the more derogatory word puns) already, I figure the way you act as “otherroute” is to use the “pseudo” command (see “sudo“). Fun, no? It made me laugh.

Back Online!

I moved recently and had all my computers off for quite a while. Now they’re back, and I intend to write about my new MythTV setup. I’ve got the backend running, and need to get a frontend on an AppleTV for my TV screen.
