Elon Musk Talks "X-Wing" Fins For Reusable Rockets, Seafaring Spaceport Drones

queazocotal Re:Back to barges? (95 comments)

Grazing the atmosphere has issues.
The heating pulse is quite large, and radiating it to cool down again before the next encounter may be an issue.
Plus, it places strong demands on the attitude control, and heats the tanks a lot when they're still full of volatile fuel.
'Just' reentering normally from what will be at least LEO takes quite a lot of heatshield or reaction mass.

Elon Musk Talks "X-Wing" Fins For Reusable Rockets, Seafaring Spaceport Drones

queazocotal Re:Back to barges? (95 comments)

The second stage, for many launches - to GEO - ends up in an orbit which is very unfriendly to reentry - if it reenters, it will do at a very high speed.
This makes reentry not simple.

UK Hotel Adds Hefty Charge For Bad Reviews Online

queazocotal Re: Not quite true (306 comments)

What the government believe is largely irrelevant to the judiciary - or at the most only a slight influence.
The feelings of the government in interpretation of legislation are at best advisory.

Elon Musk Talks "X-Wing" Fins For Reusable Rockets, Seafaring Spaceport Drones

queazocotal Re:Back to barges? (95 comments)

Current thinking is that the second stage is probably not easily reusable, and they are not actually working on it.
Those videos were produced at a tim when there wasn't a concrete idea as to how flyback would work in practice.

Jolla Crowdfunds Its First Tablet

queazocotal Re:OS/2 (56 comments)

To a degree.
A 1% niche of the mobile tablet or phone market is quite large enough for a small company.
Indeed - at that point - you're not a small company anymore.

Jolla Crowdfunds Its First Tablet

queazocotal Re:$380,000 goal? (56 comments)

i would perhaps agree - if it was from a company that had not produced hardware.
I suspect this is more the case of PR and a case to purchase early at a discount a device that was coming anyway.
I'm buying one.

'The Act renders terms excluding or limiting liability ineffective or subject to reasonableness, depending on the nature of the obligation purported to be excluded and whether the party purporting to exclude or limit business liability, acting against a consumer.'
In short - any provision trying to do this is probably not legal.

Ask Slashdot: Is Non-USB Flash Direct From China Safe?

queazocotal Re:Not a security risk, but a fake risk (178 comments)

Of course it's a security risk.
The SD card has a 32 bit processor that does the wear leveling.
There is nothing stopping it doing 'interesting' things to files on it, if it's so programmed.
The extra fun part is that the user can't read out this programming.

Obvious things might be infecting files with viruses, appending small secret files to large media files in the hope that they will later be shared, or more targeted attacks.

Discovery Claims It Will Show a Man Being "Eaten Alive" By an Anaconda

queazocotal It turned out when they actually filmed it (164 comments)

that it turned out that the anaconda had a fondness for bread products, and would not eat anything without at least some in.
The handler turned to the director, and said 'My anaconda don't want none unless she's got buns hun'.

Space Tourism Isn't Worth Dying For

queazocotal I find this somewhat disgusting. (594 comments)

Why are pilots and astronauts and F1 racecar drivers - all of which actively picked a competitive field to enter, knowing the risks - considered more special and valuable than construction workers, loggers, or fishermen?

I note that the recent 'space rating' specs imply that flying to space 12 times a year is safer - not than a logger or a fisherman - but than a librarian.

World War II Tech eLoran Deployed As GPS Backup In the UK

queazocotal Re:are you sure? (139 comments)

The satellites are hardened.
And 20000km away from earth.
As are the uplinks. (well, not the latter)

World War II Tech eLoran Deployed As GPS Backup In the UK

queazocotal Err - no. (139 comments)

The primary risk to GPS in the UK is the USA deciding to turn it off.
That risk doesn't apply for US shipping near the US, as if GPS was turned off - rather than severely degraded - so would the local LORAN locators.
GPS is not going away unless someone actually presses the button.
It's not vulnerable (theoretically) to single points of failure (ideally) as it's intended to carry on even in the event of moderate wars.

Elon Musk Warns Against Unleashing Artificial Intelligence "Demon"

queazocotal Re:Mo-tiv-a-tion (583 comments)

"This is always the problem with people imagining horrifying artificial intelligences that will snuff out humanity. To do that, you have to be motivated to achieve that end."
Well - yes.
But - it depends on the capabilities too.

Humans have wiped out many species, through direct resource extraction - like the passenger pigeon and dodo, to countless species wiped out through habitat destruction, to active extermination - smallpox.

'Terminator' style 'end of the world' scenarios only happen where there is a balance of power.
With mature AI, that has become sufficiently capable - destruction of humanity could take little effort, and only rely on a decision to do so - and the next day, everyones dead, and the resources are re-used for whatever the AI chooses to do.

This could very easily transition from a 'caring' AI that has global oversight - and provides many services to humans, through one decision to the end.

FTDI Removes Driver From Windows Update That Bricked Cloned Chips

queazocotal Re:Alternatives? Same problem.. (572 comments)

This was not a case of the driver accidentally not coping with the format of the noncompatible chips.
There would be no issue whatsoever then.
And indeed - refusing to work with the chip would be just fine.
Actively disabling the chip in such a manner that it does not work even in other computers without the driver installed was what happened.
It's only fraud if the vendor of the chip claimed to their customer it was a genuine computer chip.
A computer cannot tell if that happened automatically.

FTDI Removes Driver From Windows Update That Bricked Cloned Chips

queazocotal Re:Alternatives? Same problem.. (572 comments)

It is not complying with the USB associations rules on VID/PID.
This is not quite the same thing as being counterfeit.

If it is represented to the customer as a genuine chip - then sure.

FTDI Removes Driver From Windows Update That Bricked Cloned Chips

queazocotal Re:Alternatives? Same problem.. (572 comments)

It would have been quite reasonable to - on plug-in, put up a 'this device is using a counterfeit chip'. Banner.
(though if the chips merely reimplement the API -and do not copy the chip, and are not sold as made by the company - it is questionable if it's really counterfeit)

FTDI Reportedly Bricking Devices Using Competitors' Chips.

queazocotal Ten years inside. (700 comments)

FTDI is headquartered in Scotland.
http://www.legislation.gov.uk/...

For the purposes of the act, the serial adaptor is a 'computer' -as it's a data storage device that is plugged into a computer.
Destroying, or recklessly damaging the devices stored data is in principle worth up to a ten year sentance.

Leaked Documents Reveal Behind-the-Scenes Ebola Vaccine Issues

queazocotal Re:clinical trials. (124 comments)

What about:
80/20 - with the remaining 20% monitored more closely - with daily temperature readings - and if temperature spikes - take a blood sample, and give a high dose of vaccine. (or monitor everyones temperature, if blinding is a concern)
As I understood it - vacine - post infection is a moderately effective treatment
