I doubt a code-review would find any of these.

That is about 9500 days Iceland has Powered Itself Using Only Renewable Energy.
I will try it out.
But there is no open source server-side yet.
The problem is that there is no telephony system that you can use cross-platform, that is open source and the clients are easy to install and use for the average user.
No other heavily-used protocols have this problem, FTP, HTTP, SMPT, DNS, Torrent, Cloud Storage, VPN, SSH all have cross-platform, free and open source clients that are easy to set up and use for the average user. Telephony is the handicapped service on the internet
The main problem, as I see it, is the SIP protocol and the design mistake of relying on IP addresses in the application layer.
Almost no one has a public IP address directly on their workstation at home and it is preventing free open source telephone to be widely adopted.
What is needed is a telephony protocol that and can easily be proxied or tunneled and/or that does not need extra measurements for surviving NAT.
and what's the issue here? Trade secrets, private matters, and gossip.
The Quest for an explanation must continue.
Look, there is a bug, obviously, but to say that it is "remotely exploitable" is a half-truth, and that it is "on level with or worse than heartbleed" is nonsense.
There are a lot of things that need to "line up" in order for this to be remotely exploitable.
It is 2014 and anonymity is a crime, what country are we thinking of ?
I've been hearing all this about the much vaunted chops of these Russian coders, but frankly I don't ever see it.
There is also the possibility that the project was sabotaged by an external actor.
Maybe it is a coincidence but the one who profits the most from this failure is the same as has been working hard during the last 10 years to get rid of the Galileo program and is also the same nation as is known for being the most technically capable in electronic warfare/hacking.
Personally, I'm neutral. On one hand, the Prius and Nissan keyfobs that just sit in a pocket are cool with one less thing to flip open. On the other hand, having to stick the physical key in the vehicle with a very low power transmitter handling the passive anti-theft access gives a bump in security.
There's no transmitter in my key. You're thinking of the RFID keys, which are pretty good security: coupled with a decent quality alarm with multiple immobilizers it makes a car pretty much unstealable unless you have a flatbed.
But there's no reason you can't simply put the RFID into the alarm keyfob instead of the key. In fact, most of the pushbutton starters I've seen in recent years work exactly like that -- there's an RFID in your keyfob, and if you don't have the keyfob in your pocket (or within a few feet of the car), the car simply won't start. If the car gets out of range of the keyfob, it'll trip the fuel line immobilizer.
Modern car diesels are just under 40% efficient. The biggest diesel ship engines can just make 50% efficiency.
The current Prius petrol engine is 38.5% and the next model will be over 40%. Petrol engines are making good progress in efficiency, diesel engines less so.
A ship engine isn't a fixed RPM diesel generator, it's a variable RPM diesel engine.
What I was talking about, you need to be comparing against a diesel-oil power plant, which can exceed 70-80% efficiency. Still not as good as hydroelectric (which can exceed 95%), but aside from tidal and hydro power plants it's by far the most efficient method of generating energy that we have. It's also worth mentioning that a diesel engine can run on basically unmodified cooking oil (look up biodiesel). I sincerely doubt that your Prius would enjoy being fed that stuff.
A fixed RPM diesel is *significantly* more efficient than a car engine, on the whole. We're still not approaching the 90% that GP quotes as the efficiency for an electric, but it's enough of an improvement to still waste less energy despite the losses inherent in transmission lines.
The long-distance transmission of energy, incidentally, is where the real loss in the electrical grid comes into play. That's not really an issue when you're talking about hybrid drive vehicles. Still, I've wondered for years why car manufacturers don't design a pure electric car (plug-in), and fit it with a fixed RPM generator for extended range instead of trying to design a hugely convoluted hybrid drive train that can receive power from both. (and no, Top Gear doesn't count).
Can you explain this? I would have thought the signal would remain digital and at its original sampling rate.
It's the encoding that the HDMI decoding device supports. It does support uncompressed stereo PCM audio in the spec, but most devices will use some form of compression in the transmission, in order to reencode it as DTS or Dolby Digital for your receiver. A lot of devices do this by default, without user input, if they're connected to a receiver that can handle more audio channels. While this can usually be disabled/reconfigured, a lot of users won't actually think about that.
Case in point -- I'm watching an MKV on my WDTV Live! as I type this. I ripped the DVD myself, and know for a fact that the audio channel I'm listening to right now is AC3 stereo (though the file does have an English-language 5.1 channel). The stereo's surround sound/5.1 light is active. The device is upmixing the audio to 5.1 surround before it's sending it to the receiver.
Pound for pound, the amoeba is the most vicious animal on earth.
