Collateral Obsolescence

Posted by EricBall, 14 March 2011 · 34 views

About a dozen years ago I (with the bank's assistance) bought a house. The bank was so gracious for my business they gave me a computer, or rather a gift certificate for the IBM PC Store for an amount equal to their bargain basement Aptiva Isparati. The computer was a dog (Citrix MediaGX processor) but it was marginally better than the...

Insignia (Chumby) Infocast

Posted by EricBall, 24 February 2011 · 77 views

While on a 2 week vacation to watch the Daytona 500 (my wife is the NASCAR fan), I picked up the Chumby powered Insignia Infocast (in spite of none of the Best Buy drones knowing what one was). Now that I have it, I'm wondering what I'm going to use it for.

It certainly will function as an 8" 800x600 digital picture frame, just...

Dealing with duplicate backups

Posted by EricBall, 28 January 2011 · 31 views

I love making backups onto external drives. Plug it in and use EZBack-it-up (now I'm using robocopy) to do a simple copy of every file and every subdirectory onto the external drive. Then put that drive on the shelf until it's time to restore a file or do another backup. Not good for a bare-metal reinstall, but great for a basic file...

next gen copy protection

Posted by EricBall, 20 January 2011 · 142 views

Since the PS3's security structure has fallen, I'm left to wonder whether it's even possible to create a secure console. Secure in the sense that it prevents piracy. And if I was Sony/Nintendo/Microsoft I'd be talking to fail0verflow to contract them to help design it.

Copy protection basically comes down to making something...

Playing GT5

Posted by EricBall, 13 January 2011 · 32 views

This past weekend my step-brother-in-law gave me GT5 and a steering wheel and I've been playing it every evening. And although I'm not a hardcore racing sim driver (Mario Kart is more my style - foot to the floor) but I am having fun along with some frustration.

I'm currently up to level 8 and my current effort is trying to get...

Team Twiizers does it again!

Posted by EricBall, in Uncategorized, OtherOS 30 December 2010 · 51 views
OtherOS
Via slashdot Team Twiizers (now known as fail0verflow) has made some significant strides in demolishing the security of the PS3. (By discovering a flawed crypto implementation - allowing the private keys to be recovered.)

It makes me wonder if it is...

StarCraft 2 demo

Posted by EricBall, 27 December 2010 · 22 views

I've just played through the StarCraft2 demo for the n'th time. Part of me wants to like it, but I can't get past the basic nature of RTS - having micromanage everything in real time.

I have to say I never played the original StarCraft. The closest RTS I've ever played was Pikmin. But the resource management on that one is...

Happy birthday Xbox 360, where's your successor?

Posted by EricBall, 30 November 2010 · 61 views

Cnet published an article discussing that the Xbox 360 has reached its 5th birthday with no successor for it or its competition in sight.

The answer is simple: it's all about the money.

Microsoft and Sony initially sold their consoles at a loss to gain market share....

Panoramic photos & horizon detection

Posted by EricBall, 16 November 2010 · 44 views

One side effect of buying a new camera (Panasonic FZ40 to replace a Canon S3) is I've rekindled my interest in panoramic photos. Using Hugin (free software) a series of overlapping photos can be assembled into one giant image. Doing this requires identifying "control points" which either link to photos together (i.e. this white dot...

Fast Discrete Hartley Transform part 2

Posted by EricBall, 26 October 2010 · 42 views
Propeller
I know I said last year that it was debugged, but it wasn't. Now it is. But it's now checked out and verified from top to bottom including deriving the algorithm, the pseudo-code implementation, and the actual Propeller code. Backed up with spreadsheet comparisons between the algorithm outputs at each stage versus the base...
