Does it? To use the IOMMU for VFIO, I had to explicitly enable it via a kernel parameter.

The Bitfinex hack was due to getting enough parties of the multiparty signature to sign it (e.g. by stealing 2 out of 3 keys, or taking advantage of insufficiently secure automatic signing systems), not an issue with the contract itself.

This is effectively the announcement of discontinuation of software, and anything relating to that is usually signed. For example, Bitcoin Core release notes are signed when sent out via email, the binaries are reproducibly built and signed

Jeff Garzik was the only author of btc1, the primary 2x implementation. For it to survive for any length of time, someone needs to step up and take over code maintainership.

One of the Ethereum founders (Gavin Wood) lost the proceeds from their recent ICO to this bug. So, very good friends?

>If they used a library instead of a contract, this wouldn't have been possible. It's actually the opposite, using a library allowed this to break all the wallets using it. However, an Ethereum "library" isn't wh

You can use Janus for this - it's a server daemon that you can blast plain RTP to, and it will relay it to all connected WebRTC clients.

If a proof of work solution is economically valuable to solve, the hashrate will just increase to the point where it's just marginally profitable again.

No one has yet created a Proof of Stake system that offers the same guarantees that Proof of Work offers. In fact, there are arguments that it's not possible [1] You can implement any feature you want in Bitcoin, but for a feature like

One suggested way to use it is to basically make a "jet" for every existing Bitcoin Script [1]. Then you compose a script make exclusively of these jets and it's no worse than Bitcoin Script. Of course, I think that there&#x2

I don't know if ASN.1 is turing complete, but I don't think Simplicity can handle arbitrary depth recursion, either. Luckily, to parse a BER coded certificate, you only need a fixed depth. Of course, if you are actually parsing BE

Oh, this requires server modifications too? I had thought it was only client-side. If that's the case then it makes it especially useless for the smart contract oracle use case. If you're going to have to change the server anyway,

On the wheel, it's unsprung mass. That extra mass hurts the ability to the wheel & suspension to quickly respond to bumps, and causes energy to be lost into the suspension and tire. It's even a problem on trains - early electr

It also requires the motors to be larger because motor size mostly corresponds with torque output, not power output, and there is no gear reduction. However, it also avoids a lot of weight due to the lack of gearbox and axles, and efficienc

So, this basically has two parts as far as I can tell: 1. "signing" the contents of a TLS session (proving that they happened) 2. putting this on the blockchain I can kind of see the utility of (1), but why (2)?

In fact, in Firefox it works without creating the extension.

In the case with audio, it might be the opposite - even with a modern audio codec like Opus, an Apple CPU can decode an entire song into RAM in a fraction of a second. At that point, the CPU has to wake up anyway to download another song fr

Indeed, several good examples of these DSPs are the Qualcomm Hexagon and the VideoCore IV, the latter of which has a 64x64 register bank, and is largely reverse engineered so you can actually figure out how it works [1]. They are really goo

I'm a little bit confused too - all the operations they describe are usually quite fast on a GPU. I wonder if it's not so much about being better at image processing, but having control and direct access to the hardware. For the A

The fan's frame is plenty strong to hold it up. The only issue I see is that a baffle or case would better direct the air, allowing a lower speed fan. However, the amount of air movement required here is exceedingly small already, as c

STUN allows all sorts of hole-punching for cases where both peers are behind NATs. For cases where the hole-punching doesn't work (a user behind two NATs might be one case), you can use TURN which is a dumb UDP or TCP relay.

That's probably a bad idea - miners target profits. There was a lot of oscillation in hashrate when BCH split - and it had a lot less support. It briefly exceeded Bitcoin's hashrate. http://fork.lol/pow/hashra

You could do this with Bitcoin too. You would just send Bitcoin to an address, with an OP_RETURN with the coordinates and a hash of the pixel values you put there. Only the first one would "win". The Ethereum contract does have th

Arduino sketches don't have a "project file" to list which .c files to compile, so instead you just include all the code into one compilation unit. This works fine as most projects don't take long to compile anyway.

Thanks for this! Rikaisama had already sort of broken with e10s, and I had considered trying to port the Chrome version, but this is far better!

There's work to use Gnome client-side decorations for the title bar here, which should help with screen real estate: https://bugzilla.mozilla.org/show_bug.cgi?id=1283299 It probably won't land in time for 57, but
