I think you are missing the key ingredient in the analysis. The Economist is attempting to build such an oracle via statistical regression. HOWEVER, the Oracle is intentionally limited in input to a specific list of things: SAT scores, se

> I fail to see how those symbols being exported makes the relevant functionality public vs. internal to the kernel [1] It's not stable, but it's an API. I can write and distribute a proprietary module that uses those symbols.
603.
by amscanne 11y ago
It does. It exports many symbols for drivers (proprietary or otherwise) to use internally. Some symbols are exported GPL_ONLY, which means that only GPL drivers may call those symbols.

Reading the examples provided, it seems to be the case that they modified many of the kernel components to call directly into their proprietary component (not via an established abstraction, like driver hooks). That seems damning.

Out of curiosity, what projection would you go with?

You could very easily relax that constraint by changing a couple of lines. Rob Pike has simply chosen the classic MapReduce form. I'm not sure why you would need "proof" that generics are possible in Go. You have reflection a

But you're giving an example where you think an explicit panic is justified. Losing asserts doesn't eliminate either option. It simply requires you to have exicit error handling or a panic. This is the point.

The point is that they are commonly abused to provide error handling and reporting.

I'm not saying you must be neighbourly. If the Goatse security guys had discovered the exploit, shrugged and ignored it then absolutely nothing would have happened. They chose to write scripts, pull all the data, send it to Gawker, etc

If you're a robot that's true, but you're probably not a robot. The law leans on the word "reasonable" all the time, simply because there are plenty of situations where humans can make an obvious judgement call. If

There are several emulated devices simply because there's no way around it (the rtc, PCI bus, uart, etc.). Obviously KVM handles a fair amount of emulation (PIT, IOAPIC) which is very nice. Although the Linux implementation for 9p isn&

Do you mean that you've just discovered it, or that you've actually been using it? I have no idea how used it is. If it's useful to you, I'll happily invest more time to address some niggling issues (flakey tests, etc.)

It was go9p ( https://code.google.com/p/go9p/ ). But it was heavily modified (nearly rewritten, except fmt.go and p9.go) to suit my specific needs.

Isn't recycled paper often worse for the environment when you look at all end-to-end costs? (I suspect this would be particularly true if it needed to be white enough for digitizing.)

I don't understand your getting dressed example. That seems to be cutting to the heart of what actually was done. That's the opposite of jargon. The problem with jargon is that while it can express abstract purpose or intent (that

Isn't your math off? Due to path loss, rx signal is 1e-10mW => -100dBm, not -10dBm. Plug into the formula and we have a maximum theoretical bound of ~ 0.14 bits/second, or one byte every 42 seconds.

The site says specifically that one bridge can cover tens of thousands of devices and 50 square miles. It also seems to be based on ZigBee (that is, ZigBee devices can be retrofitted) so it's 2.4ghz, 915mhz or 868mhz. Like you said,

I had the same question. It seems to run on unlicensed (I.e. noisey) spectrum because existing ZigBee devices can be retrofitted. The tens of thousands of devices and 50 square miles per bridge makes no sense to me. That's like a cell

How can one bridge handle tens and thousands of devices and cover 50 square miles per the tech page? That doesn't make sense.
