no, thats NOT good. that means that you can be personally sued for anything that goes on with the company.
Since the lawsuit was filed by the Federal Government, let's carry this a bit further. If any employee of the Federal government (this includes judges) can be shown to have caused harm through malfeasance or negligence, then that employee can be held personally liable for the decision. Think anyone would want to work for the government under those conditions?
The Great Influenza by John M. Barrie goes into great detail how the war time censorship under the Wilson administration resulted in a significantly higher death toll in the US. The so called "Spanish flu" got its name because the Spanish press was not censored, the flu appears to have originated in western Kansas.
Packard built a radial diesel ca 1930, so there's no technical reason that a radial engine couldn't be built. The impediment is that the market for large (2,000 to 3,500 HP) radial diesel engines is not large enough to justify the costs to design and build such a beast. An L-1649 or a DC-7C with radial diesels would be cool, though the pax may not care for 20 hour flights...
The new Cessna 182 that can use Jet-A and the light sports and experimentals that can run on 91 octane unleaded are essentially in the noise in terms of total number of aircraft being produced.
Continental has expressed interest in licensing Safran's diesel engine technology for a wider range of output power. The engine is expensive enough that it may take a decade before a significant portion of light aircraft are diesel powered, though the price differential and Jet-A may encourage a fair number of engine swaps. 'Course this still leaves out the folks with big honkin' radial engines...
By the time the X-ray beam goes through the plastic wall between the source and the person being scanned, the X-rays with energies low enough to have significant photo-electric interactions with the primary elements of skin, namely H, C, N & O will have been attenuated. That leaves Rayleigh or Compton scattering for the primary interaction. Keep in mind that the cross-section for 180 degree Compton scattering is fairly constant to close to 50 keV, requiring Z's to be in the mid-20's for significant photo-electric absorption (and this is something that I found out from an astrophysics text book - most physicists, radiologists or oncologists don't seem to care about differential cross-section for Compton scattering).
There have been anecdotes about breasts reconstructed after a mastectomy showing up on backscatter as the silicone fluid attenuates the back scattered photons more than normal tissue.
You apparently don't know the difference between radiation flux and radiation dose. Dose, by definition, takes into account the interaction (or lack thereof) with matter, where a lower interaction rate for a given flux will result in a lower dose. In addition, the dose units "REM" and "Sieverts" also take into account the different biological effects of different radiation - a given energy deposition in tissue from neutrons will have a higher dose than a given energy deposition from gamma rays.
You're also a bit off base about the depth of interaction from the X-rays used in backscatter - after going through a couple of mm of plastic on the backscatter system and through clothing, all of the really low energy X-rays are already attenuated before they reach the skin. The "interaction depth" is not so much from a lack of penetration from the incident X-rays as it is the higher attenuation of the backscattered photons.
Finally, a significant portion of the dose while flying is delivered by muons induced by cosmic rays. While they do have a very long range in matter, they do interact with matter.
I was visiting a computer store owned by a friend. A man walked in who looked homeless. He wore clothes that everyone else I knew would have thrown away. This was in California before Reagan, before there were a lot of homeless people.
Reagan was the Governor from early 1967 to early 1975, and I doubt that Electric Pencil even came out before 1975. My guess the scene you described happened in Jerry "Moonbeam" Brown's first year of office.
Jerry Pournelle's first though when seeing Electric Pencil for the first time was that he would never have to retype another page again. The breakthrough with Electric Pencil was that it would run on "low cost" hardware, the magnetic tape typewriter provided similar functionality in the 1960's for about 10k$, or about the same as the base price for a Cessna 172.
It would have been nice for Aatish to go a bit into what Purcell and Pound did in their 1951 experiment, namely "inverting" the orientation of the fluorine nuclei in the presence of an applied magnetic field by application of a radio frequency magnetic pulse, where the frequency is the Larmor frequency of fluorine and the pulse amplitude and length was sufficient to cause a 180 degree nutation. The result is that the nuclei have the same order (entropy) as the rest state, but have higher energy. In NMR, this is referred to as applying a 180 degree or pi pulse.
Aatish's comment about reality being liberal is unconvincing.
My recollection is that the spontaneous fission rate for 232U or 233U is orders of magnitude less than for 240Pu. It's the 240Pu that makes making a gun type bomb from Plutonium impossible, though the spontaneous fission rate with 239Pu is at least a couple orders of magnitude larger than 235U and 233U. The critical mass for 233U is smaller than for 235U, which would make a gun type bomb easier.
I'm glad to know that I'm not the only one annoyed by "kilowatts per hour". Equally annoying is the use of "kilowatt hours per hour" when kilowatts would convey the same information.
The 2005 vintage GM (Chevy, GMC) hybrid pick-up tracks had a 120V/20A duplex receptacle n the and a 120V/20A duplex receptacle in the bed. GM had thought contractors might like it as they could run power tools on a remote job site. I was giving some thought to one of these trucks for camping, but ended up going the Duramax route.
Chapter 4 of the ARRL Handbook has a section on coupled resonant circuits. The critical coupling coefficient is equal to the inverse of the geometric mean of the loaded Q's of the two resonant circuits. With the coupling coefficient dropping with the 6th power of the spacing, once the spacing significantly exceeds the radius, the required Q's really quickly become unrealizable.
Fortran II (?) on a CDC-1700 using an IBM keypunch for punching the cards. Location was CDC's La Jolla office on what is now Eastgate Drive about a block east of Genessee.
The original version of "Blowups Happen" by R.A. Heinlein centered around an accelerator driven subcritical reactor, the only way that Heinlein thought that a reactor could be made controllable at the time the story was originally written - the story was written before the discovery of delayed neutrons from fission.
I've wondered the same as well. In the late 70's and early 80's, MS was actively supporting multiple computing platforms and weren't showing the arrogance of DRI. On the other hand, they shafted SCP twice in that time, first with the language card for the Apple II and secondly with 86-DOS.
Paul Allen's cashing out also took place about the time that work started on Windows 1.0 and not too long after Ballmer joined Microsoft.
According to Andro Linklater, Jefferson actually proposed a form of the metric system where the unit of length was something that could be determined in a well equipped laboratory - the rod with a period of one second at 45 degrees latitude. The French decided on the length of the Paris meridian, which effectively required the meter standard to be an artifact (i.e. the platinum iridium bar with two scratches on it. "Science" (metrology) didn't catch up with Jefferson until 1960, when the meter was redefined in terms on a laboratory measurement..
Too bad the speed of light was well enough defined at that time to make the unit of length the distance light travels in 1 nanosecond.
I was there and stopped by the Apple booth to pick up one of their brochures after hearing about the company from a friend. Still think it is stashed away somewhere in my collection. I was a bit more impressed by the Compucolor, but that machine unfortunately never took off.
One amusing note was finding out five years later that Trip Hawkins had also attended the Faire that year and that's what led him to join Apple.
Keep in mind that I'm probably older than her and she looks better than a good number of women my age. She does remind me a bit of a former girlfriend. OTOH, she's obviously not likely to be appearing in the SI swimsuit issue...
From some of the other posts, it looks like the OIG investigation may have had more of a reason for her leaving than she is letting on to.
She looks a bit older than when I saw her in person back around '98 or so... Still not too bad looking.
Interesting to see a reference in TFA about her having close ties with one the DARPA contractors. Heard a comment that suggested she had a close tie with one of the contractors from the late 1990's.

HP-PA RISC and M68K were both big-endian processors, X86 is little endian. My guess is you were working on an x86.

With the radiation dose equal to a few minutes of flying at 35,000', use of the system poses less of a risk than the flight.

I agree on including SPICE in this mix, in adition to giving us a powerful circuit simulator it also gave us the Berkeley license.

The reduced cooling should help in lowering the costs of the LED versus the CFL and the reduced energy consumption will be a help as well.
Red Fuming Nitric Acid, not Red Nitric Fuming Acid. FWIW, the Vanguard first stage used IRFNA - Inhibited Red Fuming Nitric Acid as an oxidizer.
