A supercomputer is any overall system that's IO limited not CPU limited like most machines. At least at full theoretical CPU use. Hard to define a rasp pi as anything other than IO limited, so... An alternative def more popular recently is programmer limited as in its hard to parallelize some algorithms. Either way it fits.
As to keeping people safe, I don't see how you could contain release of weaponized virulent infection even if you detect it early on.
Its VERY widely believed among the conspiracy theorist types that the cryptosporidium outbreak in Milwaukee a couple years (decades?) ago that contaminated drinking water and killed quite a few people by dehydration was a terrorist act, but the attack was suppressed because of military intelligence reasons, showing how incredibly vulnerable the US is in general to a bioattack. If it happened again, with a decent monitoring tool, we could save a lot of lives by issuing a water boil order quickly without having to worry about the military intelligence aspect of showing weakness.
Regardless if you believe the crypto outbreak was an attack or an accident, the fact still remains that you can create some kind of graph where every hour you wait to announce a boil order means 2.5 or 10 or whatever more deaths. It turns out that if you save a couple hundred lives it not only makes sense from a humanitarian perspective but also financial.
not something you could cook up in a third-world Jihadist lab
LOL brave words to make one feel better. But not overly realistic. Probably the same type that thinks garage chemists could never do fairly advanced organic chemisty to make meth, or ignorant savages could never learn to pilot a jetliner into a skyscraper. Or hackers don't exist on the internet.
Biowatch is a fascinating scientific tool that should be funded, should be deployed, should be scientifically incredibly valuable, and could do enormous good for all mankind.
The disaster is using it as a FUD weapon to scare people into paying more taxes, giving up civil rights, creating a culture of fear, terrorizing our own people for fun and profit.
The disaster is much like what would happen is the Hubble were launched and instead of being used for cool science research, was used to keep the population terrified of an invasion from Mars. "We must watch mars intently, awaiting the day of invasion and the resulting destruction, (btw please send us money)"
Another analogy... like using a calculus textbook as a club to beat people to death... is that really the "best" use you have for it?
Its really quite sickening to see what could have been a cool scientific instrument being used as a brutal weapon of terror against our own innocent civilian population.
Yeah I shouda guessed I buy stuff from Mouser all the time and they seem to sell everything, so...
So... $10 to $15 for the coil, and then you gotta do the interface. I looked at the TI datasheet for one of their charging chips, bq50110 or something, and the schematic is like 3 pages long and has a fair amount of analog opamp goodness. The TI chip is a QFN package, so you'd have to deal with all the whining from people who refuse to learn to solder SMD. I would wager the "usual suspects" could sell a hobbiest grade module/PCB sender or receiver for about $40.
I am fairly surprised that a consumer charger is like $40 at Amazon but just a bare TX coil at Mouser is $15. That is the not kind of markup you see in other electronics... If ardweeeeeno controllers were priced that way, and the average PIC microcontroller (OK admittedly not a ardweeeeeeno) is like $3 then an ardweeeeeno board would be like $7 instead of "about a nice dinner". Even bulk orders don't help, looking at the slope I don't think Mouser would quote much under $9 even in 1K orders (not listed, extrapolating). My guess is the cheap amazon device is not using high efficiency litz wire... litz is expensive, delicate, and a PITA to strip and solder each strand (been there done that)
transfer files from multiple incompatible systems that may not be on a network
Yeah they frown upon people jumping the air gap firewall at work, they filled the USB holes with hot glue. Supposedly too easy to spread windows viruses. If the whole point of the embedded device is not being able to upgrade either the app or the OS... you can't update the anti-virus either. I believe there's some MSSQL servers on production still vulnerable to SQL slammer from the 90s.
My sister-in-law is a teacher
Yeah I have one of those too, but she teaches K so at that age they don't require flash drives, probably because the kids are still young enough to eat them / chew on them.
As soon as you start demanding that students have... in order to be able to do their work you have immediately created an entire class of students that are not allowed to succeed.
The mystification is what success in education has to do with... being replaced above with either internet access to a cloud app or flash drives. I guess in a couple years when my kids hit 4th grade I'll find out. Anyone know an antique store where I can buy the specified "1 GB" flash drive? By then it'll be easier to buy a 1 TB SATA attached SSD, and I'm not exaggerating.
Otherwise, I will never stop sending out resumes, and will never stop looking for a better job. The instant I get a better offer letter,
I've been in this game a few decades and my only advice to add would be to pay close attention to what you're learning and what you've got access to.
I may never again work at a job with a remotely TCP/IP controllable spectrum analyzer this cool/interesting. I can surf the net while working anywhere, but only here (well, a couple other places) can I fool with deployed milspec temp grade ultra wide bandwidth medium/driver power (not small signal not high power) amps. Also this gear is smart so I do sysadmin stuff on the gear, which is both weird and cool (Think production network sysadmin stuff, not IT network stuff). Make the most out of your experience, do all the weird, odd stuff you can, unless you're doing totally generic and utterly boring stuff and there's 100 competitors where you can do exactly the same stuff. For example if you're one of the world's 10000 peoplesoft admins then doing the same thing somewhere else SHOULD, as per AC commentary, be purely mercenary.
The obvious management implication is bored employees means high recruitment expenses and vice versa. People WILL find a way to put something cool on their resume every year, and they can either do it at your company or a competitor, your choice to gain or lose...
Anyone worth their salt as a programmer who has a CS degree can MAKE THEIR OWN EXPERIENCE at ANY TIME!
Blessing and a curse. When I was 19 that was cool that I could do cutting edge stuff at home if I wanted, much easier than the chemical engineering I was transferring away from. That and what made chemistry cool to me was books like "Ignition" and "Whatever the hell the memoirs of Max Gergel CEO of Columbia Organics was called", and unfortunately? both are reminiscences of the good ole days, stuff thats hopelessly illegal now. Anyway the curse now that I'm older is I HAVE to make my own experience on my own time... at least its fun. If its going to be mandatory, at least make sure it'll be fun....
What secret iPad models are they using that interface with USB sticks?
They probably mean the existing workflow "demands" USB sticks because last time the curriculum was reviewed, 10 years ago, they were all the rage. And there's no really good way to use a flash stick with a gen 1 ipad like mine. Dropbox works great, however.
I use dropbox and google drive and haven't used a USB other than as a bootable device in... donno how many years, maybe 5 to 10 now, but my kids elementary school shopping list for 4th grade and up demands they buy "flash stick, 1 GB" which probably was pretty ambitious/expensive 10 years ago but I don't think you can buy ones that small anymore.
I would imagine once cloud storage is obsolete, the school will hire a very high priced consultant who happens to be related to a school board member and they'll review the curriculum and demand the kids use cloud storage for the next ten years.
Cool specs, but the real entertainment is trying to figure out how its like the:
'Hubble Telescope'
Do they mean the equations to design it were wrong and not tested to save money?
Or they mean the transport machine that installs and services it has been decommissioned?
It makes pictures?
Its gyros burn out on a regular basis (disclaimer, I've not been tracking this for years)
Ah they must mean its just one machine a single observational instrument. Oh that contradicts the whole rest of the write up.
Um... its a 1980s hardware design?
Oh no wait I know, it costs a billion dollars each time it's serviced, whereas it would only cost a quarter that to build another and launch it on a non-reusable booster. Yeah that must be it.
So in other words, there are no document vital to a safe landing except in a Armageddon scenario where you are probably completely screwed anyway.
Well... there's information that's pretty important, which is/was on paper, but there's so many other ways to get the same information that yeah, basically thats correct there's no document vital to a safe landing.
There are things like paper checklists which as a best practice bring your odds of surviving a normal airplane landing up from merely 99.99999% to maybe 99.9999999%, but that's not overly terror inducing especially if the pilot / copilot have some experience. I don't think they'd toss the checklists (which are pretty small and light) for an ipad. But I can see them tossing the approach plates for Alaska if you're a lower 48 domestic carrier, yeah.
Yeah thats my guess, or in true RF tradition where everything has a million other ways to look at it, you could call it AM with a low modulation index, sorta.
Lowest aviation NDB I'm aware is is around 190 KHz so you're already pissing off the aviators with the current 110-205 standard. push it lower like 80 to 100 please, not into the aviation bands. "Malfunctioning Qi charger kills hundreds in jetliner crash!" etc.
Also as far as I know Qi is worldwide, unlike almost every other charging standard. If this tech survives, you'll be able to walk into every hotel room in the world and drop your phone on the charger and it'll work.
Please don't tell me USB is worldwide. By "USB" do you mean micro, mini, full size, or that apple doc connector, and do you mean raw regulated 5V or apple wiring with the weird sense resistors to program peak current? AC line power is more "standard" than USB.
And then conspiracy theorists will of course complain about "the waves" that are "invading their bodies" and how it's going to make them sterile so all humans will die and the secret lizard people illuminati will rule the earth.
Solution: package combined Qi charger / wifi base station. Everyone knows wifi already does all that stuff, so Qi won't get any of the blame. Everybody wins!
I find it odd no one has implemented a homebrew hack of Qi.
You'd think it would be a fairly stereotypical elektor / nuts n volts / QST QEX type of article, "run your ardweeeeeeeeno off a Qi charger!" type of article.
Or if you'd prefer hardware modules, a adafruit / dangerous prototypes here's a little 1 sq inch PCB that when waved over a Qi charger outputs regulated 5 volts on these terminals.
All that's out there is sealed consumer grade end user devices, which is kinda weird compared to, say, the bluetooth or GPS or wifi or ethernet or pretty much every other "system" ecosystem.
Doesn't even have to be "hack-ish" for end user devices. Personally, as a guy who occasionally butchers wood aka wanna be finish carpenter, I'd wanna buy a little charger module for some of my projects. Here, route a pocket of specified dimensions, epoxy module in place, run power cable to wall, module is polyurethane finish compatible (or lacquer or whatever). I'm sure that would be very challenging for a roofer or someone completely confounded at the installation of a standard lockset in a pre-drilled door, but I think your average "real" woodworker could figure it out easily enough.
Its like they're trying to choke off innovation to make it fail, so they can "prove" no one wants it.
I run debian/stable and debian/testing. I think they were squeeze and wheezy, but I don't really care what the name is, why should I.
I know I've got the current most up to date in each tree, and that's all that really matters to me.
Some morning you'll wake up and your production boxes will have 500 packages waiting for installation and munin and nagios will be going bonkers due to pending packages because wheezy got released that night. No big deal, although I prefer that kinda stuff on my schedule not theirs.
The only problem I've had with squeeze->wheezy is the well reported ? perl sha hash issue where libdigest-sha1-perl has gone away so you get to go thru your source code and change all the use Digest::SHA1 statements to use Digest::SHA
if we were working on something, we specifically gave it a codename which a) the marketing guys would never ever use, and b) which made it not so obvious what it was.
The almighty GOOG is failing me now but this explains the release of some software I was using from github with the release name "Cinco de who gives a f*ck". At least I didn't have to guess what day that was released, or what he though about having to "work" on his holiday. There's another project out there using pr0n actresses names as "release names". Come on mighty GOOG, dont you index github?
Also, for most non-techies, it is easier to remember "Tiger" than "10.4"
I'd disagree on the latter. Which came first, Debian Potatoe or Debian Sarge? Damfino (well, actually I do, but,...) However every noob knows 2005 is more recent than 2000.
Where I work, internally, its all git-flow, and our releases have really boring, yet informative, names which are basically of the format:
release/`date +%Y-%M-%d`
Like today's heroic effort would be release/2012-09-11
This date structure also helps with git-flow features, obviously you can't have two "add some bs" branches but you can have "2012-06-01-add-some-bs" and "2012-08-13-add-some-bs"
If one of my coworkers gets outta whack about last monday's release I know exactly what he's talking about, that would be release/2012-08-27 Or I can even find 2012-06-18. But "Rumbly Rumpelstiltskin v2.1D" WTF is that? thats just unprofessional.
This is the "new" part. Not hard, but new. Usually you design a modulation method to minimize total power, usually you don't care about DC balance or constant power output unless there's something weird going on with the AGC ckt of the receiver.
The new part isn't so much reinventing something like manchester encoding, but considering its constant long term average power the primary feature.
I would think simple FSK would be reasonably constant power as long as LED device capacitance or lead inductance isn't distorting the signal (giving it a tilt)
What documents could they even be carrying that are considered critical/vital for a safe landing?
The ipad breaks. The paper printouts of both the pilot and copilot get coffee dumped on them (at least some pilots I know like to plan flights on their desktop PC and then print out neatly annotated paperwork specifically for their flight.... the charts for some airport 100 miles away are for emergency diversion use not daily flying) Then the pilot's phone breaks (lots of pilots have a charts app on their phone) Then the copilots phone breaks. Then both redundant comm radios break so they can't ask ATC for help (This doesn't scale if no one ever carries plates and everyone pesters ATC for every little detail every time, but a 1 in a billion accident in a crazy scenario is perfectly scalable...) Then they're too low on fuel to fly that triangle pattern (I forget the exact shape but its the pattern that means holy shit I'm lost please send me an escort) Then the mode C transponder fails so they can't change the code to emergency thus getting themselves an "escort", but the mode C failure isn't noticed by ATC who naturally think the plane just crashed so they scramble everyone over to look at you. So this is a weird situation... maybe if the transponder and its circuit breaker had superglue sprayed all over it? Then the "sat phone" system fails so they can't call the tower phone or any other person in the entire world who has charts Then every single cell phone on the plane fails... low and slow and you can use cell phones on a plane just fine... Cell network can't tell difference between my Cessna 172 at 1000 feet and 60 knots from my car on the side of a 1000 foot hill at 60 MPH... Yes, I know, its not gonna work well at 35000 feet and 500 MPH, but then again you don't have much to worry about up there. Then the landing lights have to fail so you can't communicate with a tower via morse light flashing. SOS landing lights will get them all wound up.. Then the built in GPS which also usually has charts and data has to fail (admittedly, usually no NOTAMs...) Also the pilots hand held GPS has to fail (lots of pilots have a GPS stuffed in their flight bag, right next to the flashlight) and the copilots. Then bad weather over a large area has to roll in so they can't simply go VFR approach and just eyeball it (gonna be a rough, but probably safe, landing) There have to be no other planes in the air to follow or get attention of.. The compass and a couple primary flight instruments and the clock all have to fail so they can't dead reckon their position (like over the ocean or something) Well, lets say both pilots are new to the area so they can't rely on memory.
There's probably a few other things that have to break that I haven't thought of before a ipad failure will take out a plane. Then again if more than a dozen other things listed above all also have to break simultaneously its hard to give JUST the ipad all the credit for crashing the plane.
Slashdot Mirror
Can someone advise as to what this is? Is it a report about TIRA ran thru a journalist filter, or something very much like the existing TIRA project?
http://en.wikipedia.org/wiki/TIRA_(System)
Here's NASA's version of the same thing:
http://www.orbitaldebris.jsc.nasa.gov/measure/radar.html
A supercomputer is any overall system that's IO limited not CPU limited like most machines. At least at full theoretical CPU use. Hard to define a rasp pi as anything other than IO limited, so... An alternative def more popular recently is programmer limited as in its hard to parallelize some algorithms. Either way it fits.
As to keeping people safe, I don't see how you could contain release of weaponized virulent infection even if you detect it early on.
Its VERY widely believed among the conspiracy theorist types that the cryptosporidium outbreak in Milwaukee a couple years (decades?) ago that contaminated drinking water and killed quite a few people by dehydration was a terrorist act, but the attack was suppressed because of military intelligence reasons, showing how incredibly vulnerable the US is in general to a bioattack. If it happened again, with a decent monitoring tool, we could save a lot of lives by issuing a water boil order quickly without having to worry about the military intelligence aspect of showing weakness.
Regardless if you believe the crypto outbreak was an attack or an accident, the fact still remains that you can create some kind of graph where every hour you wait to announce a boil order means 2.5 or 10 or whatever more deaths. It turns out that if you save a couple hundred lives it not only makes sense from a humanitarian perspective but also financial.
not something you could cook up in a third-world Jihadist lab
LOL brave words to make one feel better. But not overly realistic. Probably the same type that thinks garage chemists could never do fairly advanced organic chemisty to make meth, or ignorant savages could never learn to pilot a jetliner into a skyscraper. Or hackers don't exist on the internet.
Biowatch is a fascinating scientific tool that should be funded, should be deployed, should be scientifically incredibly valuable, and could do enormous good for all mankind.
The disaster is using it as a FUD weapon to scare people into paying more taxes, giving up civil rights, creating a culture of fear, terrorizing our own people for fun and profit.
The disaster is much like what would happen is the Hubble were launched and instead of being used for cool science research, was used to keep the population terrified of an invasion from Mars. "We must watch mars intently, awaiting the day of invasion and the resulting destruction, (btw please send us money)"
Another analogy... like using a calculus textbook as a club to beat people to death... is that really the "best" use you have for it?
Its really quite sickening to see what could have been a cool scientific instrument being used as a brutal weapon of terror against our own innocent civilian population.
Yeah I shouda guessed I buy stuff from Mouser all the time and they seem to sell everything, so...
So... $10 to $15 for the coil, and then you gotta do the interface. I looked at the TI datasheet for one of their charging chips, bq50110 or something, and the schematic is like 3 pages long and has a fair amount of analog opamp goodness. The TI chip is a QFN package, so you'd have to deal with all the whining from people who refuse to learn to solder SMD. I would wager the "usual suspects" could sell a hobbiest grade module/PCB sender or receiver for about $40.
I am fairly surprised that a consumer charger is like $40 at Amazon but just a bare TX coil at Mouser is $15. That is the not kind of markup you see in other electronics... If ardweeeeeno controllers were priced that way, and the average PIC microcontroller (OK admittedly not a ardweeeeeeno) is like $3 then an ardweeeeeno board would be like $7 instead of "about a nice dinner". Even bulk orders don't help, looking at the slope I don't think Mouser would quote much under $9 even in 1K orders (not listed, extrapolating). My guess is the cheap amazon device is not using high efficiency litz wire... litz is expensive, delicate, and a PITA to strip and solder each strand (been there done that)
transfer files from multiple incompatible systems that may not be on a network
Yeah they frown upon people jumping the air gap firewall at work, they filled the USB holes with hot glue. Supposedly too easy to spread windows viruses. If the whole point of the embedded device is not being able to upgrade either the app or the OS... you can't update the anti-virus either. I believe there's some MSSQL servers on production still vulnerable to SQL slammer from the 90s.

I don't think they'd toss the checklists (which are pretty small and light) for an ipad. But I can see them tossing the approach plates for Alaska if you're a lower 48 domestic carrier, yeah.

If one of my coworkers gets outta whack about last monday's release I know exactly what he's talking about, that would be release/2012-08-27 Or I can even find 2012-06-18. But "Rumbly Rumpelstiltskin v2.1D" WTF is that? thats just unprofessional.
encoding data in apparently steady light sources
This is the "new" part. Not hard, but new. Usually you design a modulation method to minimize total power, usually you don't care about DC balance or constant power output unless there's something weird going on with the AGC ckt of the receiver.
The new part isn't so much reinventing something like manchester encoding, but considering its constant long term average power the primary feature.
I would think simple FSK would be reasonably constant power as long as LED device capacitance or lead inductance isn't distorting the signal (giving it a tilt)
What documents could they even be carrying that are considered critical/vital for a safe landing?
The ipad breaks. ... low and slow and you can use cell phones on a plane just fine... Cell network can't tell difference between my Cessna 172 at 1000 feet and 60 knots from my car on the side of a 1000 foot hill at 60 MPH... Yes, I know, its not gonna work well at 35000 feet and 500 MPH, but then again you don't have much to worry about up there.
The paper printouts of both the pilot and copilot get coffee dumped on them (at least some pilots I know like to plan flights on their desktop PC and then print out neatly annotated paperwork specifically for their flight.... the charts for some airport 100 miles away are for emergency diversion use not daily flying)
Then the pilot's phone breaks (lots of pilots have a charts app on their phone)
Then the copilots phone breaks.
Then both redundant comm radios break so they can't ask ATC for help (This doesn't scale if no one ever carries plates and everyone pesters ATC for every little detail every time, but a 1 in a billion accident in a crazy scenario is perfectly scalable...)
Then they're too low on fuel to fly that triangle pattern (I forget the exact shape but its the pattern that means holy shit I'm lost please send me an escort)
Then the mode C transponder fails so they can't change the code to emergency thus getting themselves an "escort", but the mode C failure isn't noticed by ATC who naturally think the plane just crashed so they scramble everyone over to look at you. So this is a weird situation... maybe if the transponder and its circuit breaker had superglue sprayed all over it?
Then the "sat phone" system fails so they can't call the tower phone or any other person in the entire world who has charts
Then every single cell phone on the plane fails
Then the landing lights have to fail so you can't communicate with a tower via morse light flashing. SOS landing lights will get them all wound up..
Then the built in GPS which also usually has charts and data has to fail (admittedly, usually no NOTAMs...)
Also the pilots hand held GPS has to fail (lots of pilots have a GPS stuffed in their flight bag, right next to the flashlight) and the copilots.
Then bad weather over a large area has to roll in so they can't simply go VFR approach and just eyeball it (gonna be a rough, but probably safe, landing)
There have to be no other planes in the air to follow or get attention of..
The compass and a couple primary flight instruments and the clock all have to fail so they can't dead reckon their position (like over the ocean or something)
Well, lets say both pilots are new to the area so they can't rely on memory.
There's probably a few other things that have to break that I haven't thought of before a ipad failure will take out a plane. Then again if more than a dozen other things listed above all also have to break simultaneously its hard to give JUST the ipad all the credit for crashing the plane.
If you prefer platform redundancy, install "Naviator" or any of the other competitors on the pilot's (and copilot's) android phone.
