Check the reference client buglist, they got hit with a slowloris resource exhaustion combo. They fixed the resource exhaustion (kind of), they did not address the slowloris vulnerability. So again, you have no idea what you're talking

Unless I'm misreading the page, it is claiming a resolution of 104x78. So that means 8,112 LEDs. The HDSP-2132 is made of 8 character elements, each element has a resolution of 5x7. So a 80x24 terminal would have a resolution of 400x16

You are overlooking the disadvantage of not verifying the prior hash, which you can't do until you can verify hashMerkleRoot, which you can't do until you have collected the entire block. If you skip verification, you open yoursel

When you blow up the transaction limit you physically centralize the verification process. This is why you'd see miners gamble with sitting on a solved block and secretly beginning the next search, with a few seconds of head start, bef

Yes, but they will be dealing with a currency that has mathematical guarantees - which changes things entirely. Imagine a scenario in which self driving cars are not only the norm, but they've achieved a perfect safety record due to an

Oh and it gets better: known bad data is still repeated, despite the poster being told why it was bad data - over a year ago. Pointing this out results in flagging, for reasons that have nothing to do with ego or narrative continuity... sur

Yeah, the HDSP-2132 is a common display component in military hardware. I'm sure that readability figures into it (especially for NVGs), but so does hardiness. My hopes of an 80x24 dumb terminal were dashed when I finally learned the u

Yeah, it isn't something that is feasible if you can't tailor the infrastructure to the underlying data. An SQL backend is about as generic as it gets, hence the poor results. Enterprise DB deployments get away with it because the

It would be very nice if you could search based on file name, as you can with btdig.com. If you could somehow provide BRE without melting down, that would definitely put you way ahead of the other DHT index attempts.

It is surprisingly easy to find, as that stuff is pretty thoroughly covered in academic/industry journals. The only hinderance to access is a credit card number for the paywall.

Or AMD could simply knock off the binary blobs. The DRM excuse has always been weak, because it is a tiny fraction of the total firmware blob - and it'd be easy to make it so that the legally hobbled hardware decoder simply errors out
