This is a general problem with devices that are "paired". How do you securely establish the initial connection, when neither side knows anything about the other?

The secure solutions involve some shared secret between the two devices. This requires a secure transmission path between the devices, such as typing in a generated key (like a WPA2 key) or physically carrying a crypto key carrier to each device (this is how serious cryptosystems work).

Semi-secure systems involve things like creating a short period of temporary vulnerability (as with Bluetooth pairing). There's a scheme for sharing between cellphones where you bump the phones together, and they both sense the deceleration at close to the same time.

Apple's reputation management service is reacting faster now. It used to take them an hour to mod criticism down. Now it only takes 15 minutes. Who are they using?

This may be the backdoor known as DROPOUTJEEP, which was described in some Snowden-leaked documents last year.

Looks like Apple sold out, put in a backdoor, and then lied about it.

Nothing I have read about Snowden indicates that he is actually some sort of uber-hacker

Except the stuff about how a 29 year old completely pwnd the NSA, probably the most technically sophisticated part of the US Government there is?

Sheesh. Your standards are high. What would it take, exactly?

Additionally, just because you have read nothing about his programming skills doesn't mean he has none. He once mentioned finding XSS holes in some CIA app so apparently he is good enough to do that.

There are already plenty of CA's in countries that are not under US jurisdiction. However, so far the CA's that issued bad certs were all outside the USA, and appear to have only done so because they got hacked and not because they were e.g. forced to by court order.

Unless you have a magical solution to hacking I don't think your new root CA would solve much.

Additionally, citation needed for "routine man in the middle". SSL MITM has been studied by academics at scale. They did not find evidence of much. Governments don't need to MITM SSL for as long as users browse non-SSLd sites like Slashdot and browser exploits exist.

try googletranslating http://lb.ua/news/2014/07/20/2... [lb.ua] - ukrainian army detains 23 terrorists. somehow all 23 turn out to be citizens of the russian federation.

That page is merely reporting a press release from the Ukrainian government in Kiev. Are you suggesting we should treat everything they say as factually true?

let's bisect the other thing you said - "at most Russia is supplying weapons to them".
"at most". as if they were given bows and arrows. they get armoured vehicles. they get... tanks. they get bloody sam systems that can reach targets up to 25km.

Yes. That's what I said. Perhaps this is a language issue.

Whatever is happening in Ukraine it is not a full-blown invasion by Russia in the "classical" style that Iraq or Afghanistan were. That would be far more obvious. It seems to be much more similar to what's been happening in Syria where the west has been supplying weapons, training and expertise to anti-Assad groups there. If you were to say the west has "at most been supplying weapons and training to the Syrian rebels" you would be correct, given that (fortunately) Syria was not invaded by a foreign army.

Not exactly. There is a distinct difference between a soldier and a combatant. A soldier is trained and is a member of a standing military. The separatists can at best be described as "irregulars", or insurgents or rebels if you want to go with slightly more charged terminology.

Yes, really? With that definition it'd be impossible for a new military to ever be created, because anyone who joins and fights with one is not joining a standing army therefore cannot be soldiers. That is obviously nonsense, it must be possible for someone to be a soldier in a newly formed army, which is what it looks like is happening here.

Additionally, you claim that the fighters in Donetsk cannot be soldiers because soldiers are trained, and then immediately claim they're receiving training from Russia. So which is it?

And given the fact that the missiles were launched from inside territory controlled by the rebelsis a very important detail. Why would the Ukrainians have anti-air equipment deployed in an area they do not control, against an enemy with no air power?

You're quite right - it probably was the separatists. This does not change the accuracy of the Wikipedia edit that's being discussed, because unless/until the separatists win, they are still Ukrainians.

Although I'd note that given the amount of bullshit emanating from all sides in this conflict it's hard to really know anything about what's going on. The area of Ukraine that's in revolt is next to the Russian border, which is exactly where you'd expect the Ukrainian military to have had lots of soldiers and equipment stationed. Missiles might have been trucked over the Russian border, or they might simply have been there already. The separatists might be being trained by Russians (this would be unsurprising and not exactly unprecedented - see how the USA supported rebels in Syria), or alternatively they might be operating the equipment without really knowing what they're doing - indeed, having no clue what you're targeting would be rather indicative of not being properly trained, no? Or perhaps they're being trained by people who are ethnically Russian but lived in Ukraine at the time of the rebellion, or one of many other more complex cases that won't neatly fit into the "Putin fired the missiles himself" story the west is busy pushing.

All we can say for sure is that whatever you read about this incident is going to be full-blown propaganda, and should be treated as such.

I don't think Russian state media should be editing Wikipedia entries especially not on matters of current affairs.

But still, interpreted literally the new statement is far more factually correct and unbiased than what it replaced. Whoever shot down the plane, they were "soldiers" or fighters of some variety and almost certainly can be described as Ukrainian, given that everyone seems to agree that the fighters are actually eastern Ukrainians and at most Russia is supplying weapons to them.

The original text, on the other hand, more or less exactly sums up western/west Ukrainian line despite the obvious abuse of the word terrorist to mean "rebel fighter" and the [citation needed] assertion about who did it and the source of the weapons.

There is no need to get rid of Tor: in theory, Tor could have a "hidden service policy" mechanism not much different to the exit policy mechanism. HS Policies would allow a node operator to state that they aren't willing to act as an introduction point for a list of hidden services (or point to lists maintained elsewhere to stop fast-flux type behaviour).

Tor already accepts that not all relay operators will want to support all kinds of behaviour and that some kinds of traffic can be abusive, that's why they implement exit policies which allow exits to ban port and IP ranges. Taking this philosophy to hidden services seems like the next natural step. After all, Tor volunteers are ultimately acting as human shields for other people's anonymous behaviour. Requiring them to shield everything just restricts the number of people who would be willing to donate bandwidth to general privacy but are not interested in enabling botnets.

Consider trying QNX, the message-passing real time OS, for this. This is a message passing problem, and Linux doesn't do message passing well. QNX has a scheduler optimized for message passing. You should be able to handle the UDP front end and fan-out without any problems. You can give the front-end process a higher priority than the other processes, which should let you get all the UDP packets into the fan-out program without losing any. That's what real-time OSs are for.

Trying to do anything high-performance with CPython's threads is hopeless. Watch this presentation on performance issues with Python's Global Interpreter Lock, Python has an internal scheduler, and it behaves very badly under load.

So each Python process should be single-thread. Have as many as you need, set up to get work via MsgReceive and reply by MsgReply. Don't set them up as "resource managers".

Python under QNX is being used by the robotics community, where real-time matters for some things, but not others.

QNX - great technology, marketing operation from hell.

Not sure what you're getting at, but the Azul collector is well known for pulling off apparently magical GC performance. They do it with a lot of very clever computer science that involves, amongst other things, modifications to the kernel. I believe they also used to use custom chips with extended instruction sets designed to interop well with their custom JVM. Not sure if they still do that. The result is that they can do things like GC a 20 gigabyte heap in a handful of milliseconds. GC doesn't have to suck.

I thought it was in retaliation for the shelling of York (Toronto). At any rate, the British reaction, safely evacuating and then burning public buildings in the war of 1812 was far better than the Americans policy of simply lobbing bombs at loyalist civilians and exterminating British friendly native tribes.

That level of control probably belongs at the cluster management level. We need to do less in the OS, not more. For big data centers, images are loaded into virtual machines, network switches are configured to create a software defined network, connections are made between storage servers and compute nodes, and then the job runs. None of this is managed at the single-machine OS level.

With some VM system like Xen managing the hardware on each machine, the client OS can be minimal. It doesn't need drivers, users, accounts, file systems, etc. If you're running in an Amazon AWS instance, at least 90% of Linux is just dead weight. Job management runs on some other machine that's managing the server farm.

There is a serious bipartisian proposal in Congress to reduce the tax deduction for advertising. Call your Congressional representative and tell them you support the elimination of tax deductions for advertising.

Because the US savings rate is so low (most people are spending almost all they earn), advertising does not increase demand. It just moves it around a bit. All advertising does is increase prices. There are many products, from movies to medications, where the advertising cost exceeds the cost of production. Let's put the brakes on advertising.

Ripple, before the name was bought by a Silicon Valley company and changed into something a bit different, was more or less exactly this.

There's a video on the original web page that explains this concept quite nicely. You could set up debt relationships between people and denominated in any currency, including ones you invent on the fly like hours of The Real Mike's time. However it never really took off in a big way, perhaps because it was rather complicated, and bootstrapping such a system from the internet (full of strangers who don't know each other, don't trust each other and may not even exist) is presumably very difficult.

However if the concept sounds interesting you could do worse than check out the original thinking by Ryan Fugger behind Ripple. Satoshi once told me that Ripple was interesting because it was the only system that does something with trust other than centralise it.
