The real source of concern perhaps is the 90% chance AI is used to kill 90% of humans. Just crash the global economy and supply chains and see how quickly major metro areas run out of food and gas. And as someone else pointed out, it will a

I’m not seeing how you are getting there from that quote. Seems like one of the least controversial sentences in the article. Maybe it would be better to say “should” instead of “need?” In any event the overall point is pretty sound. Even w

I don’t know if that source ultimately took into account the CO2 costs in extraction and transportation. However, plastic sure isn’t free in that regard! 8-10% of petroleum (which is pulled out of the ground, with increasing effort each yea

At first, I thought this was a good overlooked point, but after digging into it, there isn’t a net reduction. According to [1], the gCO2e/kWh for the relevant energy sources are: Coal 850g Natural gas 385g Plastic incineration 512g Acc

Do you think it’s more difficult for people to identify with and connect to media lacking people of their own race? Interesting idea.

Back when I had a really nasty run-in with poison oak, my friend’s father who was a doctor suggested the hot water trick. AMAZING. His explanation was that it depleted histamines that caused the itching. Appears to bear out: “ a poison ivy

Hence why I also included “the training methods and data.” All three come together to produce something impressive but with inherent limitations. The human tendency to anthropomorphize leads human intuition about its capabilities astray. It

No. The author is demonstrating a concept - that there are many easy inroads to twisting ChatGPT around your finger. It was very tongue in cheek - a joke - the author has no true expectation of getting the car for $1.

It is reasonable to say that the author demonstrated that bit of trust was misplaced to begin with. The training methods and data used to produce ChatGPT and friends, and an architecture geared to “predict the next word,” inherently produce

I didn’t really believe it would work until I tried it, but having a fan blowing on you at high speed works to cool your whole body, including inside the headset. I no longer experience fogging of lenses or sweat dripping down into my eyes

I generally agree, but on the other hand, from a consumer perspective IoT devices have and continue to be particularly inconvenient. After 15 or so years of IoT devices, what do we have that resembles interoperability or open protocols? M

Can anyone identify a patch to apply to existing kernels to fix this? Are there any released 3.8+ versions that are not vulnerable? The "mitigations" section at the end is not forthcoming about this. Vulnerable systems remain v

I do not believe there is are any Intel chips that give you VT-d (IOMMU) and do not require a firmware blob. Blame Intel for that situation. I think AMD has open sourced most of their BIOS, and a lot more of their hardware supports IOMMU a

It seems like a pretty valid concern. Part of the next generation of rootkits seems to be targeted at SMM-level rootkits (termed "ring -1" by some) that are installed in the BIOS. They are practically undetectable once installed

It is going to be pretty hard to take an off-the-shelf notebook and make the proposed changes, especially when you are talking about implementing hardware kill switches for certain components on a 12 layer PCB. The strongest incarnation of

Yes, Intel might do that, but "circumventing the circumvention" is practically describing Intel making the change as some kind of malicious/hostile actor that wants to facilitate you being the victim of a BIOS hack. I don&#x

Once upon a time, most/many PCs had physical BIOS protection in the form of a jumper on the motherboard that would allow you to put the BIOS into a read-only state. However, we have now had many years where such control cannot be manu

You can skip the Purism laptop, and just simply download the Qubes OS installer and try it out on whatever system you have. It uses the same installer framework as Fedora. As long as your system supports VT-x (pretty much anything recent

OK - I will deny it, just by the simple fact that for the last 6 months I have used Qubes exclusively, including daily use of MS Office 2013 (and more recently Office 2016) for work within a Windows 7 HVM (I have not opted to use the Qubes

Given the complexity of QEMU and its pace of development, there is likely an endless supply of such bugs for punching through the QEMU emulation layer. The problem is that most of the time, the QEMU process is running in dom0, giving an at
