Comment Re:downgraded TP Link/Tapo (Score 1) 99

Seconded on the Tapo line. I got a Tapo C120 earlier this year and they are surprisingly cheap (currently $28 at B&H) and fairly easy to work with. I found that I needed to initially connect it to their cloud service to get their app working with it, but once that worked, I removed its ability to phone home by blocking the MAC address from the internet on my router. I can still connect to it with RTSP and stream with VLC, replay video with their app, etc. with no need for internet connectivity. Just be aware that if it can't connect to an NTP server that the timestamp in the video will be off... but you can disable the timestamp. It also logs decent resolution video and low bitrate audio to microSD which is handy. I get about two weeks of archived 24/7 footage with a 256 GB card. One drawback is that it is limited to using 2.4 GHz WiFi, which I find to have more interference than 5 GHz in my location. Everyone's situation is different in that regard though.

Social media has become a toxic dump. If you wouldn't allow children to play in waste effluent from a 1960s nuclear power plant, then you shouldn't allow them to play in the social media that's out there. Because, frankly, of the two, plutonium is safer.

I do, however, contend that this is a perfectly fixable problem. There is no reason why social media couldn't be safe. USENET was never this bad. Hell, Slashdot at its worst was never as bad as Facebook at its best. And Kuro5hin was miles better than X. Had a better name, too. The reason it's bad is that politicians get a lot of kickbacks from the companies and the advertisers, plus a lot of free exposure to millions. Politicians would do ANYTHING for publicity.

I would therefore contend that Australia is fixing the wrong problem. Brain-damaging material on Facebook doesn't magically become less brain-damaging because kids have to work harder to get brain damage. Nor are adults mystically immune. If you took the planet's IQ today and compared it to what it was in the early 1990s, I'm convinced the global average would have dropped 30 points. Australia is, however, at least acknowledging that a problem exists. They just haven't identified the right one. I'll give them participation points. The rest of the globe, not so much.

That's actually a good question. Inks have changed somewhat over the past 5,000 years, and there's no particular reason to think that tattoo inks have been equally mobile across this timeframe.

But now we come to a deeper point. Basically, tattoos (as I've always understand it) are surgically-engineered scars, with the scar tissue supposedly locking the ink in place. It's quite probable that my understanding is wrong - this isn't exactly an area I've really looked into in any depth, so the probability of me being right is rather slim. Nonetheless, if I had been correct, then you might well expect the stuff to stay there. Skin is highly permeable, but scar tissue less so. As long as the molecules exceed the size that can migrate, then you'd think it would be fine.

That it isn't fine shows that one or more of these ideas must be wrong.

Investment is a tricky one.

I'd say that learning how to learn is probably the single-most valuable part of any degree, and anything that has any business calling itself a degree will make this a key aspect. And that, alone, makes a degree a good investment, as most people simply don't know how. They don't know where to look, how to look, how to tell what's useful, how to connect disparate research into something that could be used in a specific application, etc.

The actual specifics tend to be less important, as degree courses are well-behind the cutting edge and are necessarily grossly simplified because it's still really only crude foundational knowledge at this point. Students at undergraduate level simply don't know enough to know the truly interesting stuff.

And this is where it gets tricky. Because an undergraduate 4-year degree is aimed at producing thinkers. Those who want to do just the truly depressingly stupid stuff can get away with the 2 year courses. You do 4 years if you are actually serious about understanding. And, in all honesty, very few companies want entry-level who are competent at the craft, they want people who are fast and mindless. Nobody puts in four years of network theory or (Valhalla forbid) statistics for the purpose of being mindless. Not unless the stats destroyed their brain - which, to be honest, does happen.

Humanities does not make things easier. There would be a LOT of benefit in technical documentation to be written by folk who had some sort of command of the language they were using. Half the time, I'd accept stuff written by people who are merely passing acquaintances of the language. Vague awareness of there being a language would sometimes be an improvement. But that requires that people take a 2x4 to the usual cultural bias that you cannot be good at STEM and arts at the same time. (It's a particularly odd cultural bias, too, given how much Leonardo is held in high esteem and how neoclassical universities are either top or near-top in every country.)

So, yes, I'll agree a lot of degrees are useless for gaining employment and a lot of degrees for actually doing the work, but the overlap between these two is vague at times.

There is a possibility of a short-circuit causing an engine shutdown. Apparently, there is a known fault whereby a short can result in the FADEC "fail-safing" to engine shutdown, and this is one of the competing theories as the wiring apparently runs near a number of points in the aircraft with water (which is a really odd design choice).

Now, I'm not going to sit here and tell you that (a) the wiring actually runs there (the wiring block diagrams are easy to find, but block diagrams don't show actual wiring paths), (b) that there is anything to indicate that water could reach such wiring in a way that could cause a short, or (c) that it actually did so. I don't have that kind of information.

All I can tell you, at this point, is that aviation experts are saying that a short at such a location would cause an engine shutdown and that Boeing was aware of this risk.

I will leave it to the experts to debate why they're using electrical signalling (it's slower than fibre, heavier than fibre, can corrode, and can short) and whether the FADEC fail-safes are all that safe or just plain stupid. For a start, they get paid to shout at each other, and they actually know what specifics to shout at each other about.

But, if the claims are remotely accurate, then there were a number of well-known flaws in the design and I'm sure Boeing will just love to answer questions on why these weren't addressed. The problem being, of course, is that none of us know which of said claims are indeed remotely accurate, and that makes it easy for air crash investigators to go easy on manufacturers.

Journal Journal: Audio processing and implications 1

Just as a thought experiment, I wondered just how sophisticated a sound engineering system someone like Delia Derbyshire could have had in 1964, and so set out to design one using nothing but the materials, components, and knowledge available at the time. In terms of sound quality, you could have matched anything produced in the early-to-mid 1980s. In terms of processing sophistication, you could have matched anything produced in the early 2000s.

It's far from indisputable. Indeed, it's hotly disputed within the aviation industry. That does NOT mean that it was a short-circuit (although that is a theory that is under investigation), it merely means that "indisputable" is not the correct term to use here. You can argue probabilities or reasonableness, but you CANNOT argue "indisputable" when specialists in the field in question say that it is, in fact, disputed.

If you were to argue that the most probable cause was manual, then I think I could accept that. If you were to argue that Occam's Razor required that this be considered H0 and therefore a theory that must be falsified before others are considered, I'd not be quite so comfortable but would accept that you've got to have some sort of rigorous methodology and that's probably the sensible one.

But "indisputable"? No, we are not at that stage yet. We might reach that stage, but we're not there yet.

I mean back when I was still using Windows, I once tried to get it as small as possible by boot-formating a disk and putting in more and more files until it came up. I think I ended up comfortably getting it onto a normal HD 3,5 inch "floppy". It's not that hard. Though I have never actually looked into Windows 7, but I can't imagine it's so much bigger than Windows 3.1.

I did this as well with Windows 3.11, but it required using Stacker/DriveSpace (can't remember which) and also using XDF to increase the capacity of the disk from 1.44 MB to ~1.8 MB. The end result was bootable and it could load Program Manager.

Can a non-biological entity feel desire? Can it want to grow and become something more than what it is? I think that's a philosophical question and not a technological one.

Don't agree at all and I think that's a morally dangerous approach. We're looking for a scientific definition of "desire" and "want". That's almost certainly a part of "conscious" and "self aware". Philosophy can help, but in the end, to know whether you are right or not you need the experimental results.

Experiments can be crafted in such a way as to exclude certain human beings from consciousness.

One day, it's extremely likely that a machine will say to us "I am alive. I am awake. I want..." and whether or not it's true is going to be increasingly hard to determine.
