Well, at least the artists earned some money.
I'm surprised that no one has brought up that classic economic example of a market bubble - the Dutch Tulip Mania of the mid 1600s (see the requisite Wikipedia article at: https://en.wikipedia.org/wiki/... ).
I'd like to say that I don't have a sufficient lack of compassion, morals, and ethics to dip in and out of a market like this - but really, I'm too risk-averse and lack the wit to take advantage of it.
Most of the authors are affiliated with Computer science, Engineering, Mathematics, and Environmental sciences. One is affiliated with Psychology and Brain science.
None are associated with Anthropology, Political science, Linguistics, or other social sciences.
Their thesis is appealing - but so is the model of atoms as being like little planetary systems.
This really sounds like a Tom Clancy or James Bond movie premise where the threat is to destroy a country's economy from within.
Except that a northern Chinese railroad did shutdown for a while - because it's operations were run off of Flash based software, and an automatic software update removed Flash from the systems.
You do know that natural gas regulation in Texas is a function of the Texas railroad authority.
Illuminati!
The article is a little breathless - and if water is the source of about half the hydrogen produced, then the amount of energy represented in the paste is enormous. After all, the water isn't contributing any energy to the output - if you're "burning" hydrogen in atmospheric oxygen to produce energy.
The temperature needed to activate the paste (250C) is (roughly) 20C more than the temperature at which paper burns. And if this paste DOES produce such an enormous amount of energy as to make powering a vehicle possible, then the prospect of runaway combustion seems enormous. But I'm not a chemist or a firefighter. Still, since water is involved in activating the paste, I'd worry about excess water being introduced into the system during refueling, accidents, or general aging of the equipment.
Not being a chemist or a battery specialist, I haven't compared this with lithium ion batteries or even petroleum.
How long would it take to refuel? Lithium ion batteries take up a huge amount of space in battery-electric cars - compared to petroleum tanks. Is 10x power density still result in a small enough cartridge or whatever to make refueling on the same schedule as a petroleum based car possible?
Argh! That was 10 minutes of my life I'll never get back, reading about a nonsense squabble between two crazies - although it's hard to tell which one is crazier (or more idiotic) than the other.
Back in 1995, I'm sure I saw the title of the original article. Back then, I had 2 year old - and had to be stricter about what I spent my time on than I do now, idly trolling FaceBook (where I found this article) for something a little different. Clearly, my intellectual rigor is much weaker than it was 25 years ago, because instead of finding something different from the usual rehashing of insurrection, pandemic, and economic malaise - I find this article.
In 1995, sleep deprived by a toddler and family responsibilities, and doing my small part to build the Internet, I would have quickly recognized that this was a political stunt between two whiny do-nothings, each of whom were the beneficiaries of substantial (although not enormous) privilege. Two people who'd made a career of expressing dissatisfaction and malaise, tailored to the envious who'd seen life pass them by and couldn't understand why the privileges they'd enjoyed as children were missing in their current lives.

I thought that some concern was already being given to de-orbiting (or parking) satellites and spent stages for the past few decades - and this VESPA device was launched in 2013.
Now, I can imagine that this VESPA thing - an adapter to allow multiple payloads to hitch a ride on the primary payload - might not have much propellant, so the idea of giving it the ability to de-orbit itself after use would have increased the cost of the launch tremendously. But now that cost has to be paid with an extra launch to clean up after a cheapskate initial launch. Maybe that cost ought to be paid up-front with the initial launches so that the spent stages get taken care of when it's cheaper to do so. That doesn't deal with all the junk already up there though.
Some fools are saying that this kind of problem can be solved by the free market. They don't recognize that this is actually a classic Tragedy Of The Commons situation. No single body effectively controls space well enough to enforce any ownership claims and deny access.
This particular object was chosen for characteristics that would make this demonstration project possible. This project is being touted as being commercially practical, but that is nonsense. $102 million for a demonstration likely has some opportunity for eventual cost savings as the process and technology matures - for such simple, well understood objects. But it's likely to be a grossly insufficient for less congenial objects. And there's tens of thousands of these objects.
How much debris will this demonstration project introduce into orbit?
The merits and values of open source lauded here -
The source article for this was from 2015.
Sorry, SlashDot - you've really lost it if it takes you 5 years to paste a 3rd party article in.
Enumerating such things as scroll-bars, drop-down menus, icons, and dialog boxes as high points is rather sad. Such things were STANDARD features of graphical user interfaces long before that.
Windows 1.x was an attempt to compete with Norton Commander. The Apple Mac had come out more than a year before that - and Microsoft's effort was quite sub-par to that.
Windows 1.x used a tiling windows interface, with only one process running at a time.
Network file sharing and printing was done by Novel and Banyan Vines. Microsoft's attempts at providing network file sharing and printer sharing were sad, half-hearted attempts until Windows-NT provided a stable enough platform to cut the rug out from underneath Novel and Banyan.
MIT's Project Athena had produced X-Windows, Kerberos, and AFS by then. Sun had created NFS before that.
That a product line NAMED Windows (using a common name as a trademark) has existed for 35 years IS an achievement of a sort. Many other desktop systems peaked (and died). Being successful on such a crappy architecture as the Intel-8086 instruction set had more to do with the commoditization of the hardware than anything else.
Windows is the (very) lucky winner of a relentless drive to make something (barely) good enough work on hardware constrained by commodity prices.
