Comment change to stateless API abandoned? (Score 2, Interesting) 166

3.0 was supposed to introduce a stateless API, but didn't. Now 4.0 apparently hasn't either. Have they decided that it's a bad idea, or that it's too difficult, or what?

Having the API retain state is a fundamentally bad idea. As one overview points out, "Nearly all of OpenGL state may be queried". (emphasis added)

It would be much better if there were OpenGL context objects that encapsulated the state, and were explicitly passed into API calls. I was completely dumbfounded when I first looked at API and saw that it didn't work that way.

I doubt that you could do it even then. The drive hardware most likely isn't even *capable* of recording raw ones and zeros on the media, since that's not how your data is stored. Aside from the interleaved Reed-Solomon error correction, the drive uses PRML (Partial Response Maximum Likelihood) to record multiple bits simultaneously as an analog waveform. There isn't a one-to-one correspondence between a data bit and a flux transition on the medium. This is all done by the drive hardware, so even rewriting the firmware isn't going to circumvent it.

Comment chips (Score 0, Redundant) 149

I can't RTFA because it seems to be slashdotted, but what on earth led Mr. Huang to think that Kingston made their own chips? There are only a few companies that make NAND flash chips, Sandisk and Toshiba among them, and ALL of the other vendors of flash memory cards have to buy from those few companies. The same is true of DRAM; Kingston DIMMs use other vendors' DDR memory chips.

The fact that Kingston was using chips from Sandisk and Toshiba would normally make me MORE inclined to buy Kingston cards, as usually the quality of Sandisk and Toshiba chips is quite good, though it doesn't explain why he's having trouble with them.

Comment I'm *very* skeptical (Score 1) 126

because the signals that go between a phone and a SIM don't have ANYTHING to do with the signals needed to pass data between cellular and anything else. The connection to the SIM is a very low bandwidth connection, only a few kilobits per second, because all it does is store the subscriber idenity (IMSI), PIN, and phone book. When the phone is doing EDGE, 3G, or other high bandwidth data services, none of that data normally goes anywhere near the SIM.

It might be possible to engineer something like this that would have higher bandwidth to the phone, but only by also specially engineering the phone. It's not something that could work with existing phones that are designed for normal SIM cards.

As cool as it would be if this were real, I don't see how it can be. Seems like a marketing idea, not an engineered product.
