Mechanism for emergency mission abort?
Could it be useful to be able to destruct the balloon when it flies outside of the desired area, on command from the ground (if you have an upstream radio channel), or automatically by analysing the GPS data? Would have saved the payload on the last test flight.
@trevor and all interested should take a look at yubico's products. They are primarily designed to work with LastPass-alikes, but can be used without relying on a third-party cloud service. They are rather open (implement standards, most of the accompanying software is open source), which, to some degree, can solve the trust issue. I use their token to log into my machines locally, using challenge-response mode and open source PAM module.
I am not affiliated with them, just an enthusiastic user.
Re: What's the big deal?
Admittedly, one might call it "going out of the way", especially since it is not yet implemented.
Some Internet cafes in Ohio where running a side business of gambling.
New state legislation would make such side business unrewarding (without affecting the main business).
Some Internet cafes will become unprofitable without said side business and have to close.
So what? Why are we discussing this, again?
Internet access permission?
Why would a launcher need it? I think I pass.
Re: Butane is pointess
In general, batteries have much lower energy density than fossil fuels (including butane). The power output of a camp stove is about 3 kW. However, given low efficiency of the converter, it indeed does not make much sense economically.
It's cool, though.
Cross the sea, and settle in Morocco (or something) for these five days. I think you can get more rice for £1 there than in Spain. Maybe even some lamb.
Then again, in some remote Indian village, with £1/day to spend, you'd be a rich man. Probably.
Could be a contender as a "stick it to the back of the monitor" type PC if it had more RAM...
Re: another advert for supermicro?
Indeed, Supremicro was late to the LOM party. And, at the time when I was in this business, much less reliable than the competition.
I admit my experience with light out management is dated, I am in development for the last seven years. Still - ipmi is rather problematic from the security standpoint. No audit (and usually no source available), no updates if/when problems are discovered, limited choice of connection/authentication methods. This boils down to the need for a well-maintained gatekeeper machine on premises, isolating your management network from the Internet. Which means extra cost in equipment and support, and partly defeats the purpose because you won't be able to remotely handle that machine if it fails. We could afford such arrangement for a datacenter of a few hundred servers, but if you only have a few machines on a remote location, it's uneconomical.
because Somalia is the home of pirates these days.
That, or apply for a gTLD, as other suggested.

How much help does the heater provide? Is it worth at all?
If could be useful to make measurements with the heater disconnected from the battery, for comparison.
If all you can get is 5℃, it may be not worth the effort. -60℃ vs. -55℃ - not likely to make any difference.

What does it mean?
SPEARS is programmed to issue the launch command only if the current altitude is above 20,000 metres (to be clear of air traffic) and we achieve the desired launch height.
You said it before, too, but the "and" does not make sense to me. Presuming the desired launch altitude is greater than 20000m, the first part is redundant:
if ((x > 2) ∧ (x > 5))
is equivalent to
if (x > 5)
Re: Orbital fuel dump
for the space economy to make any sense at all, we'll need propellent produced outside of the Earth's gravitational well. Lots and lots and lots of propellent. Everything else will be just marginal costs/benefits.
That is, assuming no wormholes or warp drive is invented soon.

Also, switching from cold beer to hot Glühwein (or Whisk[e]y, depending on your preferences) for the duration of the winter season should help!

No good backronym for LINDSAY?
Such a disappointment! (I admit that my own suggestion was not quite up to ElReg standards, but no one else? Pity.)
I suspect that you lived under a rock for the last decade and a half.
Nowadays, more often than not, you will open a web browser, and have your application run in a datacentre far far away, maintained by a (hopefully) knowledgeable team. And you don't need to worry about the disk or memory errors at all.
Plus, we are always fond of the past, but "easy to use"? Really? Virus free, yes, but just as virus free as your laptop will be if you never connect it to any network.
Troll because they live under a rock, too.
"With news reports of 78 per cent of Bitcoins not being spent, we need to do something,"
They hardly can do anything (long-term). Free from inflation, Bitcoin is, so to speak, too good to waste on purchases. For the money to "flow" in the economy, there must be a disincentive to keeping it under the lock. With legacy currencies, inflation gives this disincentive.

Just let us pay directly to the producers
Because currently the distribution (networks etc.) manhandle the producers into "exclusivity", and as a result everyone (sans pirates) have all the unpleasantness of ad breaks, channels filled with crap, and geographical restrictions.
Make exclusivity illegal.
Transflective LCD has been around how long? A decade? More? In handheld GPS devices, and some phones (Nokia E61 had a excellent one).
Along with the slide rule, this was definitely a personal computing device.
Definitely more personal than ENIAC and the rest of electromechanical monstrosities mentioned in the article.

Might be too expensive to send a message every ten seconds...
On the other hand, only 30g module (the board with the power supply and antenna must be heavier by still) is impressive for a two-way space communication gadget!
Extra piece of equipment to stick to the glider? Dangling wires? Don't like it very much.
Surely simply using more flammable material for the igniter will sufficiently heat up the part of the fuel that needs to fire up. After that it will heat itself. No?
Or, attach the motor to the glider in such a way that until launch it can rest inside a cylinder that is attached to the truss, and heat the insides of this stationary cylinder. (But this, too, fails the KISS principle.)
By the same reasoning...
... working on any armament should be a considered immoral. Any weapon (except a narrow case of suicidal weapons) is designed to give the wielder an upper hand, and consequently increase their chance to survive unharmed in the battle. And consequently (by the author's reasoning) increase the willingness of the government to engage in a war.
He's just read the "Kill Decision", that's all.
Exactly. Or manufacture them (jammers for cell phones, air traffic control, police radio, anything), as long as I ensure that they do not produce interference when antenna is not plugged in.
Sounds as nonsense to me.
Re: Flawed sample set? Flawed question!
oops, to correct myself, there was a separate question about being effective. Jumped to commenting before reading properly. *facepalm*
Flawed sample set? Flawed question!
Given the TSA's brief is to perform in the security theatre, i.e. to make a show to the Americans (and visitors) of how the state cares about keeping them safe, they are doing good or even excellent job. If I was asked this question, that would've been my honest answer.
The jump from "doing good job" to being "highly effective" is absolutely unjustified (unless you count "highly effective in stage performance").
If the question has been "is TSA useful for averting the terrorist threat?" then the answer would have been quite different.
Re: Put down that Axe Eugene...Microwaves can kill, easily.
I know for sure that KGB has done much worse things than the alleged microwave irradiation.
But, with some understanding of the technology, I can tell that this method having been applied is much less likely than the alternatives. For one thing, being invisible, it is very far from being unnoticeable by the victim. It's effect is largely immediate, not deferred. (And for the record, to make it long distance, you need to focus a narrow beam, and for that you need a large antenna.) Even using a Cobalt 60 gamma source would be easier, and fits the symptoms much better. That's not to mention "contact" methods like hard to detect chemical poisons.
However, as I think more about it, this story actually very well may not be a sign of the man's psychological condition, but a part of the campaign to disseminate the myths and disinformation to the public. Now, that thing was at full rage at the time, on both sides of the iron curtain.
Re: Depends on where's the wealth
All right, all right, not as real as a thousand years ago. I concede.
The point still stands.
Depends on where's the wealth
It's the consequence of proliferation of the "cloud".
Ten years ago money in the bank was as real as a thousand years ago. It was worth the effort to go and try to lift it from a bank. The banks had to learn to deal with that.
There was not enough value in what was hosted with the tech companies to justify the effort of stealing it, so the techs could afford laxer security practices than banks.
In the few recent years, more and more of the stuff that matters is going to the "cloud" which makes it more attractive target for the evildoers, so only now the shift to stricter security practices becomes justified.
Problems vs. Merits
Wikipedia and its "spiritual leader" may have all the problems mentioned in the article, and more. And deserve bashing. But at the same time, Wikipedia has one advantage compared to the projects that the article claims to be examples of "wikipedia done right".
It is useful.
Re: Put down that Axe Eugene...Microwaves can kill, easily.
High power microwaves can certainly kill. They are well absorbed by water and will heat your body inside, possibly to lethal effect. If the energy is not at lethal level, it sill is dangerous to the eyes, because there is no blood flow in them to dissipate the heat. Staying in front of a working high power radar is definitely a very bad idea.
But the idea that the adversary favoured that method over others, that it was unnoticed by the subject at the time of application, and that it caused a month-old illness (without causing blindness) does not fly with me. I stand by my assertion.
And, there was no axe here, not in the least.
Irradiated by microwaves with an intention to kill him?
I can easily believe chemical poison or short-living radioisotopes, but the claim that his own technology was used in an attempt to assassinate him is, in my opinion, a clear sign of paranoia.
Of course this is no way diminishes his achievements! There is no contradiction between being a genius and being mentally unhealthy. Especially in those times.
Forget the macbooks,

Looks like being in space also means being 15 years back in time.
Which, if you think about it, makes sense. If your kit is going to work for years, without any chance of upgrade, you might as well start with technology that is several years old. If not shiny, it's at least sufficiently well-tested.
