Executing filenames?

A year or two ago, I wrote a comedy comment about gadgets Seeing Code, Running Code.

E.g. Malicious software being spray painted onto the sidewalk, and passing smartphones immediately seeing it in their field of view, capturing it, OCR'ing it, compiling it, and of course executing it.

"CODE! MUST. RUN. CODE. Look Code !! GRAB CODE, RUN CODE."

JR shot "...let alone 200 miles away on the same track..."

Actually, one fairly detailed and seemingly plausible analysis found on an informed and skeptical-thinkers website (video?) indicates that any catastrophic depressurization will lead to a wall of 1 Atmosphere air rushing into the previously-vacuum tube, the shock wave slamming into all vehicles in the same section, leading directly to fatal level of pod-vehicle acceleration. Presumably distance would have little effect, since the shock wave would propagate quite happily along the tube for a very long distance.

This is just one of a whole laundry list of "challenges".

Possible solution - they could open valves to release air into the tube to dissipate the shock wave before it propagates that far.

"...Amazon's worse."

Dan 55 suggested that "...Amazon's worse."

Amazon Prime Video has a huge advantage over Netflix. After three minutes of browsing Amazon Prime Video, you can conclude that they have nothing worth watching (other than The Grand Tour, where we're still waiting for Season 2 to become available). So you can turn it off, and go back to doing other things without wasting a lot of time, as one might do with Netflix.

Russia launches non-TERRIFYING satellite that focuses Sun's solar rays onto Earth

Re: Some notes on satellite design.

JS19 offered, "Iridium was actually deployed with 77 satellites in Medium Earth Orbit,..."

Iridium was actually deployed with 66 satellites, plus spares and replacements. The famous "77" was replaced by 66 as a cost savings measure.

JS19 offered, "...(the atom with 77 neutrons is Dysprosium)..."

The atom with 77 neutrons is an isotope of Xenon (?). Dysprosium has an Atomic Number of 66 (i.e. 66 protons, number of neutrons varies with isotope), which may be the source of your 66 vs 77 confusion.

"...make the winters a little less harsh..."

WM suggested, "...UK's own space port putting a mirror for the North and Scotland to make the winters a little less harsh, very economical if you calculate the cost."

If you're no good with numerical instinct, then do the math.

You may (very) generously assume 1.36 kw per square meter of reflector surface, 100% efficiency, and 100% duty cycle. The generosity here is probably close to an order of magnitude. A reflector of one square km (!) focused precisely on Scotland's ~80,000 square km would be like a heater bar or two **per square km**. So you'll need a reflector *vastly* larger than km scale.

So, no.

"I ..."

I find that it's best to look back at what I wrote, before sending.

I think that starting too many paragraphs with the word "I" leaves a very subtle bad impression.

I will review and edit the wording to remove as many leading "I" as possible, preferably all of them.

I think that the resultant messages are much improved.

I know that some may not have noticed this, but I have.

I hope that you find this advice useful.

Re: AI exists?

Those that are amazed by the present state of the art in AI must have a very low threshold of amazement. There's not been any significant, discreet, newsworthy 'breakthrough' at all; just the inevitable march of Moore's Law and minor algorithm tweaks. An AI researcher from the 1960s could be caught-up in about 15 minutes.

Re: It will retail for just $35,000

SK mentioned, "...potential repair costs of....particularly the battery packs..."

Once upon a time, the Tesla Model S was in the news after an unfortunate owner left one parked at an airport with a dead battery. The news mentioned that the replacement battery pack was US$40,000+, and *not* under warranty. The price may have varied since then.

In any case, it's a safe bet that the battery pack for the US$35k Model 3 can't be US$40k.

"...practically zero communications coverage..."

VRH suggested, "...the Southern Indian Ocean and the Southern Pacific. There is practically zero communications coverage..."

Well, aside from Inmarsat (often used for aircraft) which covers almost the entire globe, roughly as far south as Antarctica (or up to *about* 80N, YMMV) [Ref: "Inmarsat Coverage",then see Google Images]. And Iridium, which provides complete 100% global coverage (everywhere legally permitted, assuming you're outdoors), presently low data rate but their 'NEXT' constellation is being launched now. And HF, which often works to some degree almost everywhere, plus or minus polar absorption caps and other annoyances. And the COSPAR-SARSAT satellites (for 406MHz ELTs) which cover 100% of the entire globe. And aircraft ADSB will shortly (already started) be tracked from orbit, again providing essentially 100% coverage.

Within a decade 'Comms' will be a "completely solved" problem (not really, but allow me to make my point anyway...), in the same way that GPS essentially solved 'Nav'. Aligns nicely with my retirement, FTW.

"This is science."

IaS offered, "This is science."

Science is proudly self-correcting, a feature that is in constant use. But few seem willing to accept the logical leap that: *therefore* a significant fraction of peer-reviewed, journal-published, widely-accepted scientific facts are (or will soon be) wrong.

Sanity Checks on the promises being made...

Far too many people are just granting the assumption that fully autonomous cars will be fantastically, almost perfectly, safe. This is in spite of the famous failures (Tesla, Volvo, others...). Okay then, so no speed limits on autonomous cars? Let them careen through the city as fast as their little "Strong AI" pea-brains will allow them. LOL...

Another idiotic assumption is that having shared vehicles that fail to stop and park when not occupied will somehow, magically-inherently, diminish congestion on the roads and somehow save energy and emissions.

Allow me to explain the issue:

M = A-to-B + Y-to-Z (morning) + B-to-A + Z-to-Y (evening)

N = A-to-B + B-to-Y + Y-to-Z (morning) + Z-to-B + B-to-A + A-to-Z + Z-to-Y (evening)

News Flash: N > M

This: Shared vehicles (autonomous or taxis) need to relocate when empty. Think about it.

Perhaps there may be some secondary or tertiary effect will counteract this obvious fact that N>M, but that's all hand-wavy magic. Too many people just gleefully assume the opposite of the direct primary effects, because they're not thinking. Telephone Sanitizers all.

Misnomer Alert

"3-Level Cells" = 3‑bits/cell, that is 8 Levels

"4-Level Cells" = 4‑bits/cell, that is 16 Levels

To be pedantic, storing 3 bits per cell requires eight (voltage) 'Levels'. Storing 4 bits per cell requires sixteen (voltage) 'Levels'.

Processing Time for coded transmissions

"...you have almost no time for that stuff."

Processing coded reflections is done with gate arrays where the signal basically falls straight through. The "processing time" to add coding, done correctly can be next to nothing.

AES-256 keys sniffed in seconds using €200 of kit a few inches away

Thirty-odd years ago...

There was a game for the Tandy Radio Shack TRS-80 Model 3 (not to be confused with the Model 1 in various "Levels") which included a musical soundtrack, to be heard through a nearby AM radio. It might have been "13 Ghosts", or similar.

Point being, the EMI was under programmer's control, and independent of other game functions.

Modern interpretation would be that the supposed key extracted by EM radiation should be a very rude phrase in ASCII, and not the actual key.

Re: Bleh

Adam 1 incorrectly asserted that, "...you ain't surviving 25G."

Note: 'g' is lowercase, unless you're referring to the universal gravitational constant 'G', which you aren't.

Wiki disagrees with your assertion: "[Colonel John Paul] Stapp demonstrated that a human can withstand at least 46.2 g (in the forward position, with adequate harnessing). This is the highest known acceleration voluntarily encountered by a human, set on December 10, 1954." Wiki provides links to more authoritative references to pre-empt the inevitable Wiki complaint.

It's actually more complicated than that. There are higher order derivatives, such as 'Jerk', 'Jounce' and others. These can have a direct impact (pun intended) when dealing with the mass of the brain in its skull.

Re: Still driving?

Famously, A.I. is hard.

Hard means incredibly difficult, far worse than anyone can imagine.

A.I. outdoors is infinitely harder still.

A.I. outdoors will require endless sensors, vastly more than they've yet contemplated. Microphones to hear the sirens. Nerves to feel the missing roof. Nose to smell the burning battery.

Helen Keller was intelligent, but not much good outdoors on her own.

Nobody has hoisted aboard much of the above.

It's hard to make A.I. when our own I. is so weak.

Hubris is the rule.

Most "A.I. For Outdoors" claims are ignorant B.S.

Self Driving Cars can be better than humans, only because we have so many idiots driving.

Distinction to be made...

The human didn't notice the truck because he wasn't even looking out through the large transparent panel conveniently fitted to the bodywork just in front of his face. If he'd bothered to look, his eyes would not have failed him.

The Tesla Autopilot has no such explanation. It had one job, and failed.

Adding to this is that it didn't even register the impact, didn't even notice that its roof had been removed, and then idiotically drove off the road and crashed.

It's clearly not fit for purpose. Hubris in a can.

How on Earth do they get away with it?
