There are lots of ways of detecting gamma rays, but one really common way is through scintillation and/or fluorescence. Most common scintillators are small blocks of plastic. I'm thinking you could increase the sensitivity of the smartphone gamma system by simply taping a small piece of plexiglass to the outside of the camera lens, using plain old black electrical tape. Then the plexiglass would convert some of the gamma energy to visible light and the camera sensor would do the rest.
So here's the part the press doesn't cover thoroughly: CGI Federal was not the Prime or Lead System Integrator on this contract. We had no authority to issue orders or assert requirements on any other contractor. Sure, CGI made some mistakes, but we can't be responsible for the other contractors when we have no contractual relationship with them!
Testing, in particular, was something CMS reserved for themselves to manage as the LSI on the program.
Again, I don't work for the CGI division that had the contract, but I do read newspapers and follow the internal chatter on this sort of thing, so I'm pretty well "up" on CGI's experiences on this project.
Nice way to go fully orthogonal ad hominem while not addressing the actual subject at hand. Did you find your debate skills in a cereal box? Froot Loops, perhaps?
OK for the record: I wrote my first multi-thousand line program in 1978. I was 12 at the time. I hold a PhD in experimental nuclear physics, a PMP certification (project management), have forgotten the details of approximately 119 programming languages that I have learned over the decades (although for some reason, good old fashioned K&R C sticks with me like a bad habit), and don't bother with certifications until my employer wants me to get one for some reason or another, at which point I do what any professional does: I go buy the book, read up until I feel confident I can pass the exam on the first try, and then pound the exam into dust.
The PMP is one example; I had to get that to satisfy the company policies when they promoted me from Chief Engineer to manager of an entire operating division that numbered about 150 people. I took the mandated class and then the exam, out-scoring every single one of the multi-decade experienced program managers who were working for me when I took over the division. Then I went on to grow that division from $24M/yr to $35M/yr in 2 years, when the company split my division in half because it had gotten too big. Then I took the $20M piece and grew it to $35M again in another two years, at which point it was (again) the single largest division in the company.
So: you are demonstrably, provably wrong in your assumptions about what I know about software engineering, business management, and probably everything else you think you can guess about me based on a single post. You also clearly don't understand the complexities of CMMI, how a company earns such a certification, and what the implications and resulting process burdens are downstream of the cert.
Surprisingly, there is one nugget of half truth in the steaming torrent of verbal diarrhea that was your unprovoked attack. You said "Your business was fucked long before CMMI even if you couldn't recognize it." The truth is that there were things wrong with the company, but we were doing just fine overall. The problem is that CMMI added so much friction to the way we worked that the previously minor problems became huge ones. The fundamental mistake the company made was playing along with SEI's demand that we apply CMMI to the entire company rather than just the division that had the mandate to attain at least Level 3. That project was OK with taking 3 years to develop 50k lines of code, and was more than happy to see costs in the $5-10 per SLOC range. The average customer is not OK with those parameters. Incidentally, the project in question was ultimately canceled (not just our part, but the entire acquisition), with sunk costs so high that it makes the taxpayer in me weep like a baby who just dropped the ice cream ball out of the cone. But we made every deadline, met every cost target, and hit every defect density goal. Thank you, CMMI, for making our customer so happy with our performance that they gave us upwards of 97% of the maximum award fee (it was a CPAF contract) but making the overall project so expensive that even the US Congress choked on the bill and killed the thing.
Hey kid, running a software business requires much more than just disparaging other professionals whose skills and history you nothing about. You need to learn what you don't know, then get back to me about...
CGI Federal didn't pick MarkLogic -- the Lead System Integrator (aka US govt) did that. I have great respect for MarkLogic and what it does, and know lots about the product...but if that had been my decision to make, ML would not have been my choice for this project.
FWIW, CGI in Canada is a substantially different organization than CGI Federal. We ("Federal") are a US corporation that operates under an SSA ("special security agreement") with the US govt in order to mitigate our FOCI ("Foreign Ownership, Control or Influence") situation. We are a wholly owned subsidiary of CGI Group aka the Canadian Mothership, but we have an all-US citizen board of directors and agreed-upon policies that limit how we interact with CGI group -- that's the SSA.
Full disclaimer: I am not authorized to speak on CGI's behalf, and don't work for the division that was involved with healthcare.gov. For the most part I only know what I read in the papers plus what I hear around the virtual water cooler. But I know a witch hunt when I see one, and that's what the Washington Post has been pursuing since 1 OCT 2013.
Actually, CGI has some great talent in both engineering and project management. How do I know this? Because I have worked at CGI Federal for three years now. The company's track record of successful deliveries is enviable in the Federal space. I say this based on 10+ years of experience in US Govt software development and contracting.
Of course, none of this is relevant to the CMMI discussion. Bringing up the CGI bogeyman as a counter example to the value of CMMI is purely intellectual dishonesty and FUD-mongering.
Not defending CMMI (IMO it's completely worthless), but I *am* defending CGI.
In 2005, my employer at the time decided to go for CMMI level 3 because it was required by a govt customer for their project. Certification achieved. Then in 2007 my employer opted to shoot for the moon and go for CMMI level 5. Again, certification achieved.
Two years later I left the company, because it was clear that CMMI level 5 was going to kill the company. CMMI level 5 introduced a high level of bloat, inefficiency, process overhead, documentation requirements, and (worst of all) process rigidity and attempts yo manage the development process by statistical analysis. Our delivery times more than doubled. The cost of delivering projects more than tripled. And the Holy Grail of reduced defect density? Nary a sign of such improvement. As far as I could tell, there was -zero- impact on code quality.
Our customers started abandoning us, our reputation circled the bowl, and everyone who had any business sense left the place in droves. What was a $100M/yr contract software development house is now down to 1/4 of the staff and revenue it had in 2009, and I fully expect their parent company will close their doors this year.
I firmly believe that CMMI Level 5 killed that company.
1) "So what" that AT&T is only going to roll out this service to "tens of thousands of customer locations throughout Austin". Google is not promising to do anything more, with a plan to deploy it to select neighborhoods based on expressed interests from residents in those neighborhoods. The real question is whether AT&T tries to roll out AT&T fiber to the same neighborhoods or if they pick other neighborhoods. I would prefer the latter just so there's more high-speed coverage around the town.
2) I am currently a RoadRunner customer. RoadRunner sucks horribly, but AT&T's service sucked so much worse the last time I used it that I fired them as soon as I could. I'm not sure I would trust AT&T to make G-bit service work, given that they couldn't make dial-up or DSL work right in the past.
3) BRING IT ON! Competition is a good thing on all fronts. I also expect (hope?) to see other communications outfits (most notably Grande) try to get in the same game, which would be *great*.
I can't help but think of AT&T's announcement as a good thing...
I have no points to mod this up, but would if I did. This is dead on target, at least as far as how the military views this sort of thing. But do remember that TS and SCI are somewhat orthogonal; you can have SECRET/SCI and TS/collateral in addition to the more common SECRET/collateral and TS/SCI.
Also note that typically NSA is comfortable with encryption as long as they know how much effort is required to break it. The only way NSA will believe a difficulty estimate is if they actually break it. They don't like schemes that they don't know how to break because that means that they don't know for sure that other people have not broken it.
That said, if NSA approves it for use in the US government, it means that they probably believe that they are the only people on the planet who can break it.
That was sort of my point. If the plumes carry away water made liquid from the tidal heating ((even a little at a time), eventually Enceladus will "run out" of water and what's left will be solid non-water material. At that point it could fracture all the way through. Oh, and the water plumes will freeze quickly once they escape, creating ice crystals, a process which would add material to the rings as well.
So tidal forces manipulate this moon enough to cause fissures to open, and stuff comes pouring out from underneath! Sounds like a fracture in progress to me, but one that hasn't torn the moon apart yet. It also sounds like there's some sort of elasticity in play; it's hard to imagine the self gravity of this small an object being a major force. So maybe when enough stuff escapes that the moon stops being elastic enough to recover from the tidal fissures, it fractures and splits?
Sounds like a perfect recipe for turning big rocks into small ones...that then resemble the stuff making up Saturn's rings.
Methinks we are seeing ring formation as a live event.
A previous employer of mine really really really wanted to offer FOSS support & products as part of their lineup. In the end, the lawyers won, as they couldn't craft a policy that would allow anyone other than a lawyer to make the decisions. This was mostly for GPLv2 and v3, but they got the dev managers completely wound up about all the license types. Mostly this resulted in the company punting on the FOSS idea.
It's not terribly surprising that some small outfit decided to outsource the responsibility, assuming they were in a similar "analysis paralysis" situation. Too bad they did not understand the intent of the licenses and just "do the right thing."
I graduated from UT with a PhD in physics, and Mike Downer was a prof while I was there. He does "femtosecond physics" ie things you can do with extremely short pulses of laser light. Pretty cool stuf, actually. Anyway, a petawatt laser (10^15 W) fired in a femtosecond (10^-15 s) has a total energy of ~1 J per pulse...they're really not giant gizmos.
Message: the lasers in question aren't petawatt CW, but pulsed.
Whoop-de-doo. There are several outfits that have done something similar over the years, including companies that have tens of thousands of fingerprint devices out on the street already.

The only law restricting cash that I know of concerns crossing a US border with more than $10k in cash, and even then you just have to declare the fact that you are carrying more than $10k. The act itself is not illegal.
Inside the borders of the USA, your comment about merchants being prohibited from accepting cash for a purchase is completely nonsensical. "Legal tender for all debts, public and private." That's what it says right on the note.
I'm not sure that carrying $100k in cash would stand up as "probable cause" for a search in most courts unless there were other factors involved...
My wife has a Kindle and uses it almost exclusively to check out e-books from the Austin Public Library. They have to be reserved through the library and transferred by Amazon, but she says the process is easy enough to manage. I know she has read upwards of 100 books in the past ~18 months this way.
So if libraries already have a working process for lending e-books for Kindle (and presumably other readers), I have to ask why someone thinks they need this "digital media library" approach. I assume that this is all political and/or publicity oriented, but I have to ask whether the money wouldn't be better spent elsewhere. If nothing else, loaning delicate electronic equipment to the public seems like a frightful risk.
It would also be interesting to see if there are structural anisotropies in the dwarf galaxies, and if so, are those anisotropies oriented any particular way with respect to the planes of Andromeda or the Milky Way, or the orbital plane of the dwarves in general. If my guess about tidal effects is correct, I would expect the answers to both of the above questions also to be "yes."
The kid probably did most of the coding, but used data gathered by other observations at the observatory (or even other observatories). The idea probably came from his father. This is exactly the sort of straightforward project you would assign a bright undergrad (or high school student) to do. It's relevant, mostly easy, and might possibly generate a new result. You can't ask for much more.
This isn't a case of a judge just tossing out the 4th Amendment. The situation is that the cops had a court order allowing them to grab the location data from the cell towers. It wasn't a warrant, but IANAL and I don't really understand what the difference is between the two. At any rate, the courts knew what the police wanted, and gave them the go-ahead.
What the judge did in this case is duck the 4th Amendment issue completely, and seemingly intentionally. She ruled that since the cops had a court order, they were entitled to grab & use the cell data. It's clear that she didn't want to wade into the 4th-A discussion, preferring to punt that to another court -- quite possibly the supremes.
If the cops had gotten a "warrant" to get this data, I doubt anyone in the press (or on/.) would be interested in this case. So now we're down to arguing over whether a "court order" is different enough from a "warrant" to be worth putting on our Big Brother war paint.
The thing that worries folks in Japan is not the suitability of the engineering or the technology in general. The problem is the Japanese culture of silence, cover-up and cronyism. When you're faced with something potentially as disastrous as a nuclear plant meltdown, you want to have reasonable assurance that the government is actually *regulating* the plant operators, not participating the in cover-ups and denials that problems exist.
Nuclear power actually has a pretty good safety record, except when plant operators do something patently stupid (Chernobyl), criminally stupid (Fukushima), or just plain make a mistake (Three Mile Island). So what you really want is to know that the government is looking out for the public's best interests, and not allowing plant operators to do stupid things...but in today's Japan, that's not what happens.
Can the LDP change that culture? Probably not, because frankly they have been in control of Japan for most of a really long time. They *are* the problem, in many ways. If you're a Japanese citizen, the LDP wanting to re-start Japan's nuclear plants probably doesn't sound so great to you.
There are two proposed explanations for the signal seen at CMS, and I'm not sure I would describe either as "new." The color glass condensate is basically a nucleus that is flattened into a pancake due to relativistic length contraction in the direction of motion at high energies. This flattening effect spawns large numbers of gluons (the particles that mediate the Strong nuclear force), wich in turn exposes all sorts of interesting effects. The quark-gluon plasma is a state presumed to exist shortly (say, 10 microseconds or less) after the Big Bang, when the universe's energy was packed into an extremely small volume. At high energies and small distances, quarks (the components of hadrons i.e. protons and neutrons) and gluons are thought to separate easily, creating a hot soup of strong force particles. As the QGP expands and cools, it eventually "freezes out" and you get a shower of normal matter particles. This, too, is thought to have happened after the big bang.
Both of these conditions have been observed at the Relativistic Heavy Ion Collider (RHIC) in the USA. The CGC was reported in 2003/2004, and the QGP in 2010/2011. So while observing them at LHC is exciting, neither is really "new." LHC's luminosity is much higher than RHIC's, though, so one would expect to be able to study both conditions more readily...
Yes, but creating a quark-gluon plasma is more than just energy. You have to get the nucleon (protons + neutrons) nice and high so you have quarks to deconfine to make the plasma. That's why BNL and CERN use heavy nuclei like gold and lead in these collisions. In a string theory experiment, you would probably just go for protons. My guess is that leptons (electrons, muons) would be a better choice for string theory experiments, but they lose too much energy going around the ring in cyclotron-style accelerators so you have to go with linear accelerators instead...which then limits the energy you can impart to the particles.

Total cost? Probably around $0.05 total.

OK for the record: I wrote my first multi-thousand line program in 1978. I was 12 at the time. I hold a PhD in experimental nuclear physics, a PMP certification (project management), have forgotten the details of approximately 119 programming languages that I have learned over the decades (although for some reason, good old fashioned K&R C sticks with me like a bad habit), and don't bother with certifications until my employer wants me to get one for some reason or another, at which point I do what any professional does: I go buy the book, read up until I feel confident I can pass the exam on the first try, and then pound the exam into dust.

So what you really want is to know that the government is looking out for the public's best interests, and not allowing plant operators to do stupid things...but in today's Japan, that's not what happens.
Can the LDP change that culture? Probably not, because frankly they have been in control of Japan for most of a really long time. They *are* the problem, in many ways. If you're a Japanese citizen, the LDP wanting to re-start Japan's nuclear plants probably doesn't sound so great to you.
There are two proposed explanations for the signal seen at CMS, and I'm not sure I would describe either as "new." The color glass condensate is basically a nucleus that is flattened into a pancake due to relativistic length contraction in the direction of motion at high energies. This flattening effect spawns large numbers of gluons (the particles that mediate the Strong nuclear force), wich in turn exposes all sorts of interesting effects. The quark-gluon plasma is a state presumed to exist shortly (say, 10 microseconds or less) after the Big Bang, when the universe's energy was packed into an extremely small volume. At high energies and small distances, quarks (the components of hadrons i.e. protons and neutrons) and gluons are thought to separate easily, creating a hot soup of strong force particles. As the QGP expands and cools, it eventually "freezes out" and you get a shower of normal matter particles. This, too, is thought to have happened after the big bang.
Both of these conditions have been observed at the Relativistic Heavy Ion Collider (RHIC) in the USA. The CGC was reported in 2003/2004, and the QGP in 2010/2011. So while observing them at LHC is exciting, neither is really "new." LHC's luminosity is much higher than RHIC's, though, so one would expect to be able to study both conditions more readily...

Once in a while, Randall really nails it.
Man, are the educational publishers going to get cheesed about this.
Yes, but creating a quark-gluon plasma is more than just energy. You have to get the nucleon (protons + neutrons) nice and high so you have quarks to deconfine to make the plasma. That's why BNL and CERN use heavy nuclei like gold and lead in these collisions. In a string theory experiment, you would probably just go for protons. My guess is that leptons (electrons, muons) would be a better choice for string theory experiments, but they lose too much energy going around the ring in cyclotron-style accelerators so you have to go with linear accelerators instead...which then limits the energy you can impart to the particles.
