Comment Front car ESP? (Score 1) 253
I wonder, did the driver of the car hit by the wheel had remarkable driving skills or the car was stabilized by the ESP?

>All the energetic particles trapped during the journey have to go somewhere, and the researchers believe they would be blasted outward in a cone directly in front of the ship.
At that energy levels particles will be converted to gamma radiation, expelled outward in a burst. Maybe sombody already invented those ships.
One of those guys actually has a PhD in nuclear engineering. I'm sure he never imagined being presented as an Artist
You don't patent an ABI. If you do, then nobody could make compatible toolchains without paying to do so.
Alright Genius, I confused ABI with ISA.
How did your post get modded +2? Where have all the real geeks gone?
Thank for sharing you enormous knowledge, noy you can go back to your real-geek only club.
I always wonder, why change the ABI so often? after all the instruction set is only the interface between the C compiler and the underlying VLIW CPU engine. That's why the first 64 bit processors were actually slower in 64 bit than in 32 bits, and even today they aren't that faster in 64-bit mode.
I suspect is all a Patent game, that's why CPU designers keeps modifying the ABI. Their patents are expiring all the time.
1) Fire: You can build your entire machine on metal, that won't prevent the thing you are cutting from catching fire.
Nitrogen canister, regulator, pump to measure gas volume... enclosed container. Fire needs oxygen to burn.
The only deadly thing a Laser lacks is something that can explode and throw shrapnel at you. Now it have it.
2) Smoke: There's a reason most laser cutters have huge ventilation tubes. The laser will produce smoke, if you cut anything but wood it will be toxic smoke. Not good.
Seal the equipment in an air-tight chamber, vent it to atmosphere when safe or pass exhaust through activated-carbon.
Instead of toxic smoke now we have concentrated pressurized toxic smoke.
3) Laser: 40 watts is 100 times the power needed to instantly blind you. Lasers of that power are dangerous even bouncing on non-reflective surfaces. The laser is probable IR so invisible too.
Safety interlocks to prevent chamber from being opened while laser is active; Viewing ports made of laser-safe safety glass to absorb specific wavelength of laser beam (same as the safety goggles you should know to wear...).
Good luck absorbing 40 Watts in 0.1 mm^2 of glass though.
And IMHO the worst: The high-current high-voltage power source (10 KV or more) can instantly kill you.
Isolation transformer, sealed unit, zero-delay ground return fault interrupt from mains, capacitor buffered to smooth initial load during firing (which would otherwise trip the aforementioned). Proper grounding. Oh, and proper grounding. And proper. Fucking. Grounding.
Now you're right, these things are all dangerous and can kill you... but so can climbing into a hot tub if you're drunk. You can't make something perfectly safe, but you can make it reasonably safe. Your microwave also contains a power supply rated for similar voltages... and similar risks for body damage if the safeties are compromised.
Fair enough. When isolating the stuff remember 10 KV can kill you through a 5 cm air gap.
Yes the microwave can kill you that's why there are no DIY microwaves.
I used to work programming laser cutters. Let's summarize the ways these machines can kill/maim you:
1) Fire: You can build your entire machine on metal, that won't prevent the thing you are cutting from catching fire.
2) Smoke: There's a reason most laser cutters have huge ventilation tubes. The laser will produce smoke, if you cut anything but wood it will be toxic smoke. Not good.
3) Laser: 40 watts is 100 times the power needed to instantly blind you. Lasers of that power are dangerous even bouncing on non-reflective surfaces. The laser is probable IR so invisible too.
4) And IMHO the worst: The high-current high-voltage power source (10 KV or more) can instantly kill you.
The company I worked for had huge problems with the certification of the power source alone.
DIY 40W Laser = terrible idea. CNCs are much cheaper and safer.
Exploit-Proof was one of the main requeriments of OpenBSD when it started 17 years ago.
I got 6 years of uptime once off of NetBSD on sparc.
Congrats but you should never do it in something connected to internet. You would be using a 6-year old kernel that's ridicously vulnerable to 6-year old exploits.
Not much. Her perception is only clean cut men in suits are successful. Any deviation in hair cut alone branded one as a hooligan.
To be fair with your grandmother, her generalization was correct during most of her life. Until 2011 spacecraft were designed and controlled by clean cut men.
And when the attacker inevitably finds an exploit and installs a rootkit anyway, they'll change the keys so you can't install the officially signed BIOS.
Exactly. You can't really protect a generic computer from unknown software bugs. Also if you have physical access is game over anyway, you could replace a big enough piece of hardware with a malicious one and that's it, pwned.
A physical jumper would cost extra money. How about a NON FLASHABLE bios?
No, sorry that's crazy. BIOS updates are essential to fix security bugs. A non-flashable bios would make your system *more* insecure.
The physical jumper would help in some situations, but not all, let me explain: I'm one of the guys cited on that draft, we made a pretty generic bios rootkit that worked fine. One of our attack scenarios inclueded having physical access to the device before the victim, I.E. you receive an already rootkited laptop/PC. A jumper wont help in that case, only a signed BIOS would. It sucks because it smells a lot like DRM but very often security and freedom are mutually exclusive.
I find interesting that the draft cites a Phrack issue. If a NIST cite do not legitimize a journal, I don't know what it does.
I want Tesla coil demonstrations (the kind he used to do with electricity arcing all around the room). I want "build you own X" areas for kids to build cool things. I want smart, exciting people giving smart, exciting presentations about what engineering and technology makes possible.
Then you want to hire this guy, Photonicinduction to work in the museum seriously check out his videos they are great.
Research in electrical engineering in 2050 will be done by kids visiting this museum now and realising how awesome it is.
I've noticed several design suggestions in your code.
