A dyno doesn't lie (much) and yes you can get more HP out of a motor by changing the fuel and ignition maps, but as soon as you change mechanical components to inrease the volumetric efficiency of the engine, your $400 chip is fueling wrong.
I didn't say a chip doesn't work - I said it's a waste of money if you want to operate a non-standard motor, and you expect to make changes outside those that the chip programmer designed for.
Put a free flowing exhaust on, or add a K&N and your VE goes up. Add a bigger intercooler and increase the inlet air density. Change the cam and your fueling needs change, as well as possibly your idle needs if you want a smooth idle on a lumpy cam. Maybe you need to change your VVT setup as well to make the best use of a new cam profile.
Unlike parent AC who has no clue about how this shit really works, I've actually written the code that runs on these things, and written software to tune them. It's not magic and computers can't pull HP out of their arses. Yes there are gains to be had with "chipping" your car (advance ignition, increase boost, richen mixture, adjust shift points, etc), but the chip has to match the engine to get the best results and a programmable system is the best way to get that.
It's actually supermount that provides the names for the drives. To rename them, you just rename/mnt/cdrom to/mnt/cdrw (or whatever) directory available and edit/etc/fstab to reflect the change.

If you peruse eBay, you'll see people selling replacement chips for around $400 that are supposed to add this many horsepower.
And unless you buy a matched kit with cam, inlet, exhaust, etc, you're just gambling that it will work better than your existing setup. If you're paying $400 for a chip, you'd be better off buying (or building) a programmable computer instead. Then spend some dyno time and get it set up right.

It's generally not the "code" that's being hacked, but the data lookup tables. Sure, you could rewrite your engine's algorithms and maybe add some features, but all most people do is edit the fuel map to richen the air/fuel mixture and balance the mechanical mods they've made (exhausts, air inlet, etc).
Yup. We sure take for the current systems for granted. I mean, these days, even my car's EFI computer is much faster than the ZX81 and similar machines I started out with.
They won't touch the existing licenses because they are not affected by locality. I'd imagine this will suffer from the usual export restriction bollocks that the US Government likes so much.
Eureka! You know that whole carbon nanotube space-elevator thing? Every design I've seen uses a single platform in space to hold it up. How about a few (hundred?) balloons placed along the length of the elevator to hold the sucker up and in position? C'mon, I dare ya - tell me why that won't work./too much coffee
Tell that to my lecturers. I'm sure it's unrelated, but those students who were "well behaved" got consistently high marks regardless of actual output. Either that or they put out for the lecturers (it's always the quiet ones...).
That's not a bad idea at all. I think most ISPs would rather buy their certs from FSF or similar. The only difficulty would be getting Microsoft to ship certificate updates to the masses.
It's interesting that you mention Microsoft. I was thinking how this would impact them, as suddenly their Internet Explorer DNS redirects won't work - I can't see them being happy about Versign stealing their customer's eyes, so to speak.
If they go ahead with this, I suspect we will find out...
On a similar note, how about an industry wide boycott of all Verisign certificates. The next round of certificate-extortion goes through someone else, and uninstall their root certs too - I'd hardly call them "trusted" after pulling this junk again.
Go back under your bridge, troll. Outsourced means outside your company, not outside your country. I'm sick to death of US based fucktards acting like their countrymen are above any sort of misbehaviour.
Fair enough. In that situation, I'd look at something like Python. You can start them off with proceedural "Hello World" stuff, and then move into classes as they get their heads around it.
I'm not sure Java is the best language to start with, but the whole OO idea relies on being able to visualise code as objects. Having taught OO coding to various folks, I can say that it REALLY doesn't work for some people. They can follow program flow, but they can't visualise objects "talking" to each other.
BTW, I think the best way to handle OO programming is not some text editor, but an immersive 3D enivronment where you literally build objects and connect signals. That would r0x0r.
Well that depends on your definition of an invention. If you see code as literature, and for copyright to apply then you must, there's no such stipulation.
What this has to do with Aussie I don't know, but yes you will still have jobs.
Globalisation is still moderated by your government maintaining excessive tarrifs, and at any rate stuff is already WAY cheaper overseas, it's just that US importers screw it up to "market rates." The only thing making this work is producers allowing exclusive sales areas, and (I think) no laws specifically allowing parallel imports. But if imports are cheaper than what you can produce domestically then so be it. That's the market at work. Do it better, faster, or cheaper...
FWIW, my family produces products that are exported to the US, and I believe the importer makes more on it than we do. We also sell to EU and AP region, and the products retail at significantly less thanks to the local reps.
Well, given that this is supposed to be a Fedora prelude, and given that Fedora is supposed to be a RedHat ES/AS/WS prelude, I'd say the "bounty" is theirs when they get to market it commercially as "un-crackable".

True. Having now RTFA, it seems that the focus of their concern is "juris-my-diction" of the license. Code export being a seperate issue altogether.

Maybe "future BBC reporter" would be close?

Wow, you guys did something revolutionary - now give it to me.
EVMS wasn't actually accepted into Linux by Mr Tovalds. About the only place you'd find it was in SCO and United Linux kernels.
Well, given that this is supposed to be a Fedora prelude, and given that Fedora is supposed to be a RedHat ES/AS/WS prelude, I'd say the "bounty" is theirs when they get to market it commercially as "un-crackable".
Or maybe I'm just cynical.
