You don't need any custom sensor hardware to read the disk as the original drives have signal lines that provide all that's needed. They usually have some automatic gain control, but it usually gives the right result.

You still need to connect the drive to a cheap device like the Greaseweazle (USB), which reads the raw flux reversals from the surface (plus timing information) as they're picked up by the drive head. All data decoding is done in software on the host system, which can handle ANY encoding type, and be smarter about error recovery.

The disks themselves sometimes need a bit of manual cleaning to be in a good position to read. Not everything can be recovered but older disks are generally more reliable than cheaper newer media.

That will still be a problem, as any properly HDCP-compliant capture card will not (or should not!) give you access to the data either. Every device should check the downstream devices are compliant before passing any data on, and not provide any way to intercept it. Any that knowingly do are breaking the HDCP licensing agreement and are likely to be sued.

Comment Copy protection? (Score 2) 101

You'll probably run into copy-protection issues with many media sources. If you can get at the bits to analyze it, you can dump them out to create a copy. I'm not even sure sharpness is going to be easy to measure, if a soft/low-res source has been artificially sharpened to give the appearance of quality. Sports broadcasts seem to be the worst for it for it from my experience, with glowing halos around high-contrast edges to make them stand out even more.

Software

Bad Software Runs the World 349

whitroth tips a story at The Atlantic by James Kwak, who bemoans the poor quality of software underpinning so many important industries. He points out that while user-facing software is often well-polished, the code running supply chains, production lines, and financial markets is rarely so refined. From the article: "The underlying problem here is that most software is not very good. Writing good software is hard. There are thousands of opportunities to make mistakes. More importantly, it's difficult if not impossible to anticipate all the situations that a software program will be faced with, especially when — as was the case for both UBS and Knight — it is interacting with other software programs that are not under your control. It's difficult to test software properly if you don't know all the use cases that it's going to have to support. There are solutions to these problems, but they are neither easy nor cheap. You need to start with very good, very motivated developers. You need to have development processes that are oriented toward quality, not some arbitrary measure of output."

Comment Re:Pointer typedefs (Score 1) 394

I've never come across that mix of separate attributes with defined types. Typically there will be a PCFOO to go with the PFOO, which has the const as part of the typedef: such as LPSTR and LPCSTR.

Typedefs allow you to keep the whole type atomic. I prefer:

PCSTR p1, p2;

to

const char *p1, *p2;

where the pointer symbol needs to be repeated on the second variable, despite 'const char' being common to both.

Games

Submission + - Wipeout recreated with an RC car (geek.com)

An anonymous reader writes: If you’ve owned any of Sony’s PlayStation consoles then there’s a good chance you’ve also played one of the Wipeout, games. It’s a high-speed racing game that helped make the PSOne popular, and it’s now been recreated using a remote control car.

The project is the idea of Malte Jehmlich. He decided to create a track out of cardboard reminiscent of the Wipeout tracks. He then hooked up a wireless camera
to a remote control car, and modified the controller to be an arcade cabinet with a wheel and forward/reverse selector.
