Short version is that weapons are optimized to use the absolute minimum fissionable material and reactors are optimized for an engineering reasonable heat flux per sq meter.
The cost of building an ICBM to carry something "just 500 pounds heavier" is enormous. The motivation to make weapons lighter is intense. On the other hand PWRs need to keep heat flux low enough to not boil at a sane flow rate, and BWRs REALLY need to stay in nucleate boiling mode. This means a reactor is insanely heavier than a weapon.
A normal human can pick up a modern weapons physics package. Well you have to be in.mil and lift weights occasionally, not your average people of walmart. But the point is the fun stuff is pretty light. A reactor core is made out of hundreds of modules each of which requires a rather heavy crane to lift individually.
Another way to put it is if you want to light it off, it needs well under 100 pounds of the fun stuff. But if you want to reliably extract a gigawatt or so for a couple decades, there's some thermodynamic and materials science reasons that ANYTHING that can transfer a GWt over the long term is gonna be tons. Doesn't matter if the heat came from U or Pu or coal, its gonna take tons of metal to reliably transfer that heat into water. Kinda like if you wanna fire, a match isn't all that big, but a GW class coal electrical power plant, which also uses fire, is really heavy.
This was what my first modem around 1982 used to connect to compuserv. It was a TRS80 "modem 1" direct connect modem and I remember the answer/originate switch. Yes I'm a noob compared to some real old timers.
I am an ATP Pilot turned computer programmer. There is no shortage of pilots, just a shortage of pilots willing to work for 18k a year and be treated like crap.
So its the same working experience, except you don't get to fly. Also, H1B for computing, but not piloting... yet. These kind of articles are the drumbeat... I bet money that within 10 years domestic airlines will have exclusively non-american pilots, just like very few american cruise lines have american captains or american registered boats.
No. The general public has the stupid idea that flying is dangerous. Its actually the safest form of transportation ever invented, for a variety of reasons. That means there's a long way to go before its really as dangerous as, say, driving a car. We'd have to have a daily plane crash before aviation is as dangerous per mile as driving, and practically hourly airline crashes to be as dangerous as bicycling or walking/hiking per mile. So rest assured, a lot of people will die before things would get "fixed".
$440/hr average is probably on the high side even for heli.
Probably he's getting a bachelors degree with it. There are programs like that on this side of the pond too, all for profit operations mostly interested in booking student loans. Graduate in 4 years with a BS in aeronautical engineering AND a commercial cert. Some provide an excellent education, but ALL overcharge.
There are people graduation with liberal arts degrees an $100+K in debt and NO pilots cert
The term you need to google for is "loss leader". Its a marketing term. It turns out, that if you intentionally eliminate a free market by giving every participant a semi-random different price, then you can't do your financial estimates using any old random price, because you might pick an extreme tail of the price distribution. An airline doing its financial planning based on every ticket being a $10K 1st class last minute booking to the other side of the planet would be equally screwed.
The other thing is, one was to end any argument on the internet is to take it urban. I've taken taxis in NYC and its like $50 flat rate from Manhattan to the major airports. Thats why I took Amtrak last time I went to a HOPE conference, which is right across the street from Penn station anyway. So, because the pilot fee is meaningless if you live in NYC, I invoke the "internet rule" that its now meaningless everywhere.
Disney Channel's Phineas and Ferb is my 2nd favorite show on TV
They manage to include a lot of pop culture / adult humor (adult as in funny to adults, not merely adult as in swear words) without being sickeningly sarcastic. It is a good laugh. I found the Simpsons to be a little too self referential and can't stand south park. Other than the ben heck show, its probably the TV show most likely to have an Ardweeeeno tie in episode. Or show most likely to have a makerbot tie in episode.
LOL oh spare me before I hurt myself laughing. Very long and complicated and unlikely story vs... Occams razor suggests that maybe, just maybe, if management feels some laws and regulations WRT to documentation and filling out W-2 forms are optional for them, maybe, just maybe, they might also think some food safety laws and regulations are also optional for them. Simplest solution that makes sense is probably the most likely to be correct.
I'd much rather see restaurant monitoring. You should be able to eat at McD and taco bell w/o spending the next 24 hours on the porcelain throne.
What kind of digestive problem(s) do people like you have??
I have absolutely no problem eating fast food. No one I know has any problems, either.
Exactly like I wrote, it depends on your locale.
Where I live, restaurant A makes everyone sick every time they go there especially if they buy an egg-based breakfast, I assume they're only still in business because of interstate travelers and/or being a corporate franchise the rest of the company is keeping them afloat. Restaurant B upon reflection I'd give 10% to 25% odds you'll get sick, no real pattern. Are you feeling lucky, punk? Its a pity because as fast food goes it actually tastes pretty good. Restaurant C has never, in dozens of visits over the years, ever, gotten anyone in my family sick. I named names for my locale, but its probably all shuffled up in different locales, maybe "C" has the idiot manager somewhere else so they get everyone sick, even though the "C" here has an absolutely perfect reputation. Maybe by some miracle, as you claim, your local health inspector is un-bribable or its just incredible luck of the draw or whatever.
I'm pretty much bulletproof, digestively speaking, if I cook it myself, partially because I'm not an idiot and partially because I care... I don't like food poisoning and its remarkably easy to avoid, if you want. I visited Mexico and ate at reasonably upscale restaurants, enjoyed it immensely and didn't get sick, despite being told everyone gets sick in Mexico.
Somebody's "cold table" is as warm as 60 degrees or the "hot table" is only 110 and a couple hours later you will barf too. Or the other end explodes. Or both at the same time. Plus or minus some vermin infestation, improper sanitation rules being followed, etc. Despite all the strangely appealing and repetitive stories about fast food workers adding extra protein to the meal, the main problem is infinitely more likely to be the same unwashed knife and unwashed cutting board cut up raw chicken right before it sliced your tomatoes and raw onions. Or the raw egg scramble mix sat at room temperature before partial cooking for the entire breakfast shift midnight to 10 am. Or the salad vegetables were stored underneath the dripping raw chicken boxes in the cooler.
As for the protein additions you'd think this would be a major pr0n problem but I've not heard any discussion of it so I'm thinking as long as the perpetrator is not filthily disgusting its not going to make you sick... Come on,/., think about it, if merely touching a weiner resulted in instant guaranteed painful food poisoning I think teenage pregnancy rates would be a hell of a lot lower, either than or teen girls would be "sick with a tummy ache" a heck of a lot more often. Not to say swapping bodily fluids is safe, merely not insta-death, or (thankfully) not a common health problem.
(1) A person is guilty of an offence if, with intent to cause a person harassment, alarm or distress, he— (a) uses threatening, abusive or insulting words or behaviour, or disorderly behaviour, or (b) displays any writing, sign or other visible representation which is threatening, abusive or insulting, thereby causing that or another person harassment, alarm or distress.
Hey you Brits, did you hear that after the recount, it turns out Rmoney won?
(Oh F looks like I'm about to get extradited by pretty much every country except Jesusland that has a "distress" clause like this)
It does superficially sound extremely uncivilized and backwards, consider the 60s civil rights marches, which certainly were disorderly (by the definition of apartheid order) and certainly caused some distress, by crackers terrified they'd have to share drinking fountains. Unimpressed.
I actually misread the headline as "... for photo of burning puppy..." and I was duly outraged and saddened.
And then I read TFA and
I was mystified about the whole poppy thing which apparently has a completely different meaning in the UK than in the US.
Here in the US, it seems a random roll of the dice if you'll get arrested for growing poppies due to the whole "harvest for opium" thing. No growing, no harvesting, no wearing, no burning no nothing WRT poppies depending on where you live and how cool the cops are.
Apparently you people who mis-spell stuff like colour and your fags are made out of tobacco (fag means something entirely different here in Jesusland, trust me), staple hard core drug production leaves to your shirts on your equivalent of memorial day. It does make a certain recent sense in terms of victims of war needing painkillers which used to come from plants, but in most of the USA doing stuff like that would probably just get you arrested.
I guess the closest american analogy would be President Thomas Jefferson grew weed, so to celebrate his birthday we'll staple pot leaves to our shirts, sorta. Not a bad idea, really. Um, I'm just growing for Jefferson's birthday holiday, yeah thats it.
If someone ever does produce an actual cloak of invisibility, we're going to have a huge problem as
In the good olde days on/. this would have rapidly devolved into "how are 5000 nerds wearing invisibility cloaks all going to simultaneously fit in the 12 person college cheerleaders girls shower room and what happens when their crappy homemade wiring and/or ARDWEEEEEEEEENO microcontroller shorts out because of the shower water?" but no, we have to have whacky hollywood movie plots about murder.
Insider trading is a much more fun example. What did the corporate board really talk about? And how much can you blackmail them?
For better or worse, circumstantial evidence seems enough to convict. Also invisibility seems to have nothing to do with DNA samples, motives, etc. I'm not anticipating a serious murder problem.
More realistically, I predict that if invisibility cloaks are perfected, about 30 seconds later every college cheerleader girls locker room is going to have a grid of what looks like spiders webs hanging from the ceiling. Those icky 70s bead curtains may make a comeback. Outside of the ladies gym showers, in "secured" areas, I predict the "spiders" will involve conductive, energized thread that's only deactivated when my NFC RFID is marked as approved. Also you'd be surprised what someone could do with semi-toxic gasses if you really wanted. I would not want to try to rob a bank vault after some fairly obvious countermeasures are deployed.
Unidirectional microwave-only cloak -> omnidirectional visible light cloak? It's gonna take a little more than "a few years".
The biggest problem I see from having done lots of RF engineering in the lower microwave range (mostly FCC part 97, but some telco work, aside from the wifi stuff that "everyone" does) is specs always improve, but the basic layouts / schematics / ideas don't change very much.
Higher freqs? Sure. A heck of a lot of orders of magnitude? Um, maybe, over the course of a lifetime and billions of bucks. Unidirectional to omni? Um no.
You can make a "better" horn antenna. You can do crazy stuff to eat the sidelobes. You can make it lighter, or wider bandwidth, or better behavior when it multimodes. You can make it lower loss. But fundamentally, its still a microwave horn antenna. This fundamental issue is analogy to trying to make a unidirectional cloak.
This doesn't mean its useless. You know what would be funny? A anti-anything missile that is radar invisible from the pointy end. Who cares if you can see it from the back or side, its too late by then. To the best of my limited knowledge from playing Harpoon, etc, all American anti-anti-ship missiles are radar guided as are the ancient Phalanx miniguns.
One interesting RF observation is its a serious challenge to "really" do microwave RF work over a factor of 2 in freq. Can be done, but doesn't mean its easy or its more than cheating (multiple colocated systems... making a big pile simply isn't technologically interesting). The relevance is an X-band invisible car would probably not be invisible at K band. Or something invisible to red is probably going to be blue visible, unless you run multiple systems. Or something invisible to blue is probably not going to be invisible to IR targeting lasers.
Then again, it wouldn't surprise me in the least if there was a "I have Herpes an proud of it!" group on Facebook - considering how narcissistic and self-entitled people are these days.
That would probably be a much more accurate predictor of people with stupidly easily guessed passwords, or people who don't lock their phone, or people who leave their PC logged in and walk away... More of a computer security predictor than a bio security predictor.
Now "I survived the H1N1 flu" MIGHT be actually useful because I'm not seeing it turned into a joke prop. Maybe flu researchers would play tricks on each other or something but 99% of the population would use it seriously, probably.
The normal RICO style bribe is somewhat less than 1/10th. So yeah the contract "shoudda" only been about 6 mil. There's a lot of wiggle room, I'm sure this isn't their only contract, and I'm sure that PAC isn't their only bribe paying system. But its not too many orders of magnitude outta line for what tax money they're getting vs what they paid to get it. They don't seem to be getting too much or too little contract for the "donations" they provided, compared to everyone else at the feeding trough.
I'd much rather see restaurant monitoring. You should be able to eat at McD and taco bell w/o spending the next 24 hours on the porcelain throne. However for practical reasons everyone knows you can't, locally. Its NOT the type of food... You can eat greasy burgers at a regional chain and giant burritos at a national specialty chain all week without getting food poisoning because they are actually sanitary. I have noticed a trend that places that actively ignore immigration laws oddly enough seem to ignore sanitation and food safety regulations, who ever wouldda thunk it, so after several food poisoning incidents I don't go to restaurants staffed exclusively by illegals.
Note that this monitoring is fed level / national. Food inspection is done locally but you'd think an entrepreneur could set up a business to feed them leads. I'm sure the PR/marketing people would like to know which of their restaurants make people sick. Another interesting aspect would be calculating 4sq checkins vs twitter reports of food poisoning and the "winners" use the stats in their commercials as the restaurant least likely to make people sick or whatever.
I will say my local Culvers (a regional burger joint) never got me sick not once never, the flypaper covered with flies in the kitchen and smelly fly filled bathroom Wendys was about 50/50 odds, the taco bell looks clean but also 50/50 odds, and you may as well say last rites and/or sell pedialyte/gatorade and immodium with every meal instead of kiddie meal toys at the local festering McDonalds. This information, replicated by a couple million online and statistically analyzed and correlated, should be monetizable in many different ways, not just the "24" "fox news" "neocon" "lets keep them scared to keep them controlled" fatherland security goon squads.
Remarkably verbose article. Somebody's getting paid by the word... The TLDR is: "much like the rest of the economy, the velocity of money is on the decline in the VC/startup field".
If they grade on a curve and you're on a scholarship, I can easily imagine a "fair price" being too much for your competition to pay.
This technique is nothing new nor limited solely to 1st yr engineering. I was completely automating high school math problems including printing all intermediate results/steps two decades ago on a TI-81.
on android I use hc-16c and free42. Wolfram alpha if you allow "cloudy" solutions.
There are a couple hp48 emu but the buttons are too small on anything other than a tablet.
If anyone can find better math software for an android device, post here?
Odd how you can get decent software on cruddy hardware, or cruddy software on decent hardware. I'd like something as powerful as a HP48 but not emulated... native. I know octave is available on android but the keyboard situation is icky.
I've been LOL about this idea, but Maybe, just Maybe... what if they had a thundering herd of VNC servers in da cloud and the "website" is just a VNC client?
No need for legacy HTML shit simulating a client server app in the most complicated byzantine and slow means possible... Have a couple traditional client server apps for different resolutions, like my full size high res desktop and another VNC server for my tiny little phone. Each VNC server is a cloud image, created when I connect and vaporized when I disconnect for "security".
Basically your "website" is an icon running your off the shelf VNC viewer and a hard coded hostname. Thats all.
Its not that horrible of an idea, in that case. Now using HTTP as the transport instead of VNC would be pretty dumb, but VNC as a transport? Hmm maybe.
You forgot they'll only certify it for certain OS and if detected on the wrong one it'll refuse to work and pop up a "please upgrade" message.
And it'll demand you downgrade new platforms. So your vista laptop can't log into your bank.. pop up claims you need to "upgrade" to XP or more likely 98.
"This page best viewed 640x480x8... here, since I'm a poorly written app now with system access instead of being a poorly written webpage, let me reconfigure your video card to be BankOptimized(tm)(c)"
The largest security hole is likely to be the legendary ability for apps not to get updated on a timely basis. So they'll be a new buffer overflow in the cookie cutter app for my credit union and it'll take them 6 months of consultant contracting and testing and security approval and certification and SSL keysigning and roll out plans and maint windows to get it pushed. Meanwhile I'm getting owned for half a year. Oh well, I'm just a user, and they have procedures to follow. Meanwhile the "old fashioned" "insecure" "legacy" Chrome users had it patched in chrome hours after the exploit was discovered and have been safe for half a year.

Short version is that weapons are optimized to use the absolute minimum fissionable material and reactors are optimized for an engineering reasonable heat flux per sq meter.
The cost of building an ICBM to carry something "just 500 pounds heavier" is enormous. The motivation to make weapons lighter is intense.
On the other hand PWRs need to keep heat flux low enough to not boil at a sane flow rate, and BWRs REALLY need to stay in nucleate boiling mode. This means a reactor is insanely heavier than a weapon.
A normal human can pick up a modern weapons physics package. Well you have to be in .mil and lift weights occasionally, not your average people of walmart. But the point is the fun stuff is pretty light. A reactor core is made out of hundreds of modules each of which requires a rather heavy crane to lift individually.
Another way to put it is if you want to light it off, it needs well under 100 pounds of the fun stuff. But if you want to reliably extract a gigawatt or so for a couple decades, there's some thermodynamic and materials science reasons that ANYTHING that can transfer a GWt over the long term is gonna be tons. Doesn't matter if the heat came from U or Pu or coal, its gonna take tons of metal to reliably transfer that heat into water. Kinda like if you wanna fire, a match isn't all that big, but a GW class coal electrical power plant, which also uses fire, is really heavy.

Another interesting aspect would be calculating 4sq checkins vs twitter reports of food poisoning and the "winners" use the stats in their commercials as the restaurant least likely to make people sick or whatever.
I will say my local Culvers (a regional burger joint) never got me sick not once never, the flypaper covered with flies in the kitchen and smelly fly filled bathroom Wendys was about 50/50 odds, the taco bell looks clean but also 50/50 odds, and you may as well say last rites and/or sell pedialyte/gatorade and immodium with every meal instead of kiddie meal toys at the local festering McDonalds. This information, replicated by a couple million online and statistically analyzed and correlated, should be monetizable in many different ways, not just the "24" "fox news" "neocon" "lets keep them scared to keep them controlled" fatherland security goon squads.
Remarkably verbose article. Somebody's getting paid by the word... The TLDR is: "much like the rest of the economy, the velocity of money is on the decline in the VC/startup field".
If they grade on a curve and you're on a scholarship, I can easily imagine a "fair price" being too much for your competition to pay.
This technique is nothing new nor limited solely to 1st yr engineering. I was completely automating high school math problems including printing all intermediate results/steps two decades ago on a TI-81.
on android I use hc-16c and free42. Wolfram alpha if you allow "cloudy" solutions.
There are a couple hp48 emu but the buttons are too small on anything other than a tablet.
If anyone can find better math software for an android device, post here?
Odd how you can get decent software on cruddy hardware, or cruddy software on decent hardware. I'd like something as powerful as a HP48 but not emulated... native. I know octave is available on android but the keyboard situation is icky.
TLDR X.25 with big buffers
Then we would have discovered 100% of all stars were created in exactly 4004 BC I assume on the first day according to the neocons.
I've been LOL about this idea, but Maybe, just Maybe... what if they had a thundering herd of VNC servers in da cloud and the "website" is just a VNC client?
No need for legacy HTML shit simulating a client server app in the most complicated byzantine and slow means possible... Have a couple traditional client server apps for different resolutions, like my full size high res desktop and another VNC server for my tiny little phone. Each VNC server is a cloud image, created when I connect and vaporized when I disconnect for "security".
Basically your "website" is an icon running your off the shelf VNC viewer and a hard coded hostname. Thats all.
Its not that horrible of an idea, in that case. Now using HTTP as the transport instead of VNC would be pretty dumb, but VNC as a transport? Hmm maybe.
You forgot they'll only certify it for certain OS and if detected on the wrong one it'll refuse to work and pop up a "please upgrade" message.
And it'll demand you downgrade new platforms. So your vista laptop can't log into your bank.. pop up claims you need to "upgrade" to XP or more likely 98.
"This page best viewed 640x480x8... here, since I'm a poorly written app now with system access instead of being a poorly written webpage, let me reconfigure your video card to be BankOptimized(tm)(c)"
So something more akin to a telnet session?
LOL

I'm sure they'll be places using c3270 too!
The largest security hole is likely to be the legendary ability for apps not to get updated on a timely basis. So they'll be a new buffer overflow in the cookie cutter app for my credit union and it'll take them 6 months of consultant contracting and testing and security approval and certification and SSL keysigning and roll out plans and maint windows to get it pushed. Meanwhile I'm getting owned for half a year. Oh well, I'm just a user, and they have procedures to follow. Meanwhile the "old fashioned" "insecure" "legacy" Chrome users had it patched in chrome hours after the exploit was discovered and have been safe for half a year.
Friends don't let friends use apps!
