Comment HP Is Being Cheap (Score 4, Interesting) 121

ChromeOS, in contrast, comes with more stringent system requirements that would cost HP a bit more.

In other words, this thing is going to be really slow if you try to use it for serious work. Why? Because HP is cheap and doesn't want to shell out for decent components. That and/or they like their locked down bootloader.

They say "randomly" generated coefficients, but I'll bet you can use a psudo random number generator and pass in the same seed value to both the sender and reciever. Bam, now both sides have the same set of semi random coefficients to use when doing the fancy linear algebra.

Comment Re:Why do they need their own spaceport? (Score 4, Interesting) 40

Out of curiosity, what do they need their own spaceport for, especially if (as an earlier poster notes) they only intend to launch about once a month? Are there constraints on the use of launchpads at Cape Canaveral, where there's already been a great deal of investment in building launchpads, support structures, etc.?

That's a part of it. Without looking into the details, Cape Canaveral doesn't seem to want to deal with more than one rocket launch within a week of each other. Wile the US Gov launches from Vandenberg, they also launch from Cape Canaveral. Plus the Orbital Sciences launches, other commercial launches, and everything else that happens there. The current story is often launch attempt one aborts, launch attempt two has a delay to make sure they fixed the problem, then it's a several week delay because Cape Canaveral had another launch planned.

The other reason is the idea of recovering the Falcon 9 rocket. It could be easier to launch from Texas and recover at Cape Canaveral.

Comment Re:ASLR (Score 1) 125

If you think a bit further... An operating system could load an executable at a different address every time it is used, without recompilation!

The problem with ASLR is that it involves Position Independent Code. The absolute addresses may change, but functions are called by their relative addresses to each other. When you know were one function is you know were all the others are as well. A mild example of this new randomization technique is to randomize the file order being fed into the linker. Different file order means different function layout. Then even if you know where one function is you don't know where all the others are without looking at that individual binary.

Like I said, cost is king.

Heck, I've been trying to redesign something to use the ATTiny and bitbang USB. Thinking about it, that's where the 4k number came from. Boards with more memory and more features are getting cheaper and that's awesome. I can't wait for when integrated USB becomes as common as integrated SPI and TTL.

Now if you'll excuse me I need to get out of my cave and yell at some kids on my lawn.

Where did 4K of code come from?

I would expect to use a micro that can address enough memory for the job to be done right.
Who mentioned Arduinos? It wasn't me.

I was just talking in general. When someone says "simple microcontroller" I think of an ATMicro/Mega or something like the MSP430 most of which cap out somewhere between 2 and 16k. Anything more than that is a full ARM soc and normally is expensive and has finicky power and i/o requirements compared to the "simple microcontrollers" I normally work with. They're the lap of luxury since, like I said, you normally spend large amounts of time to make the code work with the 4k device instead of the 16k just to save a few cents per unit.

That seems like a good thing for a voting machine.

Good for voting machines, bad for anyone who doesn't need any fancy features but needs more than 4k Bytes of code. Since that's your entire program space with those small microcontrollers. You find weird bugs and limitations in many of those since they have to use a stripped down libc. When you hit that code cap most of the time your only option is to redesign the entire board or start using hacks to cut down on code size. The Arduino might have popularized them, but microcontrollers are still a game where you spend hundreds of thousands of dollars up front just to save ten cents per unit.

Also, since it's much more of a pain to update code don't expect things to be patched unless they're critical. Even then it would be really expensive. Worse, since these things still use a stack you can still get them via Return Oriented Programming.

SD cards are actually even easier since you can talk to them over SPI. You can get a fifty cent microcontroller to read and write from those with no problem. The annoying thing is that those microcontrollers use a Harvard architecture. Instruction and data code use entirely different memory. So you can read and write to an SD card, you just can't run code off it.

It sounds to me like they're finally admitting that this is a basic service that everyone should be provided with.
I wonder how much longer it will take before they regulate it as such (as a utility).

The thing is that the FCC (US government agency that regulates telecoms) can do that. It's what the whole Title II reclassification thing is all about. http://www.washingtonpost.com/... Which is why the lobbyists and congress are freaking out. https://www.techdirt.com/artic...

This should have far reaching ramifications when it comes to copyright law. As long as the original video or photographs were made consensually or in public then the photographer owns the copyright. I don't see how that can be undone. It also should open the door for further defining what exactly entails "compromising the reputation". What if someone takes a (non-sexual) photograph of a person cheating in public? Or a video of someone acting like a jerk? Those would also compromise the reputation of the subject. I wouldn't be surprised if this gets overturned higher up.

That was my thought as well but remember the story about right to be forgotten. That case said it's ok to censor someone and have them remove totally factual articles and links. It was the online equivalent of if you don't like what someone said about you in a book then they have to stop printing it and pull it from store shelves, and bookstores have to remove all traces of it ever existing from their system.

It would have been a totally different lawsuit if it happened across the pond. Here in the US this would have been Copyright and First Amendment (both explicitly given to the gov) vs something much more nebulous (defamation or publicity rights maybe). Of course, here in the US they've determined that the first amendment doesn't cover "obscene" speech. Pity they don't really define obscene.

Another thing is that in most marriages the assets are merged. It's always tricky to divide everything in the divorce. The common (American at least) feeling is "she gets everything, and he gets to keep the clothes on his back."

The ideal use for mini projectors is when you need to give a presentation and don't want to deal with the hassle of setting up a projector and then connecting a laptop to it. The ideal projector has a USB port for a thumb drive on the back and automatically starts whatever powerpoint is on there. Add another USB port for the presenters remote and you're golden.

Business people don't like having to worry about cables and configuring multiple monitors. Heck, I don't either when I'm crunched for time and there's an audience staring at me and waiting for me to get it all working.

"Zero-Day exploit allowing the attacker to run arbitrary code"

I thought these words should be history based on the implemented NX bit, sandboxing, multiple lines of defense and Data Execution Prevention features of MS Windows after XP.

Why do all these features fail, when they are specifically designed for exposed code like IE? Or does this warning assume the worst case, where all these other features are turned off?

The NX bit, and DEP forced us to develop Return Oriented Programming https://en.wikipedia.org/wiki/... Basically because function arguments and return pointers are on the stack you can make the code that's already there do the work for you. It's not as easy as just writing a little shell code and tends to be more specific as far as the version of the software the victim is running, but it's really quite neat and hard to stop.
