The amendment process for the Constitution is not for the faint of heart. The usual method is to have a 2/3 majority of both the houses of Congress pass the amendment, and for that amendment to be ratified by 3/4 of state legislatures. There is no way in hell that amendment would ever get through Congress, let alone the state legislatures.

Scientists publish their completed research in scientific journals. There is no genuine reason for publishing emails that were exchanged whilst the research was still in progress. Only in-genuine and dishonest reasons.

"Police offers present their completed incident and arrest reports in court. There is no genuine reason for publicly releasing recordings of what the officers do whilst the incident and arrests were still in progress. Only in-genuine and dishonest reasons."

Just saying. Seems to me if you're going to have public employees, you need to hold them all to the same standards of transparency.

I am working as a consultant.

My good advice to every customer is: dont buy consultant work as time and material. Buying as time and material puts the wrong incentives to everybody:

-Your own people will feel that they still can just use them as normal workers and keep all decisions (and thus responsibility) to themself

-The consultants dont care, since just doing what your own people tell them without thinking is what gets their monthly timesheets signed. If something goes wrong they can even sell more hours, not less

-The consulting company does not care (and rigthly so since that was not what you asked for) and will send you inexperiences junior consultants wherever possible.

-Coding quality has to be reviewd by your own people (or just accepted as it is)

-Your own people are usually vastly inferior at project management in comparison to the average senior consultant - in a non T&M contract the usual situation is that you get the things done in time or you will loose money.

Chernobyl would not have been prevented by putting the reactor in water. It was the only accident which had a "nuclear power excursion" as the reason. TMI and Fukushima were a failure of the classical cooling.

In Chernobyl the operators ignored the normal precautions. They operated the fuel in a state where xenon (see http://hyperphysics.phy-astr.g...) was present. Due to this the system was far away from the assumed stable oprtion point assumed in the controls.

The power which you would have needed to dissipate at the event to cool the reactor would have been ong the order of 200GW. Normal heat transfer coefficients are on the order of 10s of KW/m^2/K if i assume that you allow 200K difference on the surface, you end up at an active cooling surface of 100000m^2, which just is not there, not even if you drop the reactor into water.

Mind you, I am pro-nuclear.

Meanwhile, the biggest issue that faces most nuclear plants under emergency conditions â" overheating and potential meltdown, as happened at Fukushima, Chernobyl, and Three Mile Island â" would be virtually impossible at sea."

Simply being at sea doesn't prevent the cooling problem. Remember, Fukushima was right on the ocean. The problem is that the cooling system has to have at least two loops. An internal loop of coolant (usually water, though salt has also been used) actually travels inside the reactor. Consequently it picks up some residual radioactivity from being exposed to all those neutrons flying around. You cannot just use this single loop for cooling, or else you're releasing this radioactive coolant into the environment.

A second external loop of coolant cools the internal loop via a heat exchanger. This external loop picks up nowhere near as much radioactivity, and the coolant (water) is safe to dump back into the environment.

If it were just one loop, you could come up with a clever design using thermal expansion to make the water flow through it to provide passive cooling in the event of a pump failure. But with two loops (and the inner loop being closed), you're pretty much reliant on active pumping to remove heat from the reactor core. The problem at Fukushima was that power to these pumps failed, and backup generators designed specifically to supply power in that scenario were flooded and their fuel source contaminated.

I don't see how putting the plant on a floating platform helps in this scenario, unless you're willing to open up the primary cooling loop to the environment and just dump water straight into the reactor (with the resulting steam carrying both heat and radioactivity out). Which was pretty much what they ended up doing at Fukushima. If they'd done it before the cladding on the fuel rods melted, we'd only be dealing with a small amount of radioactive water (deuterium, tritium, etc) being released into the environment as steam, instead of fission byproducts being directly released. So I don't see how being by vs on the ocean makes any difference for this scenario.

Maybe you could design the steel containment sphere to act as a heat sink, allowing sufficient cooling when submerged? But the containment's primary job is to contain what happens inside. That's why it's a sphere - it encloses the largest volume for the least amount of material and surface area, and its mechanical behavior under stress are very easy to predict. This is precisely the opposite of what you want from a heat sink. You want the most surface area for a given enclosed volume. Which makes me suspect that the steel containment could only operate as a heat sink if you're willing to compromise its protective strength somewhat.

The other problem I see is that putting it out at sea hinders accessibility. Meaning more mundane events like a fire, which are trivial to handle on land, become much more problematic at sea.

...What you're probably thinking of is "ignorance of the law is no excuse"...

Which is it's own level of BS when you think about it. It's predicated on the idea that you're responsible for making yourself aware of the law, so that you won't violate it in ignorance. But today's body of law is so great that I'm not sure it's possible for a person to read it all within a single lifetime, let alone piece together all of the cross links and understand everything that applies to you.

The authors and passers of the law bear some responsibility for violations when the law is so verbose and numerous as to be an impediment to understanding.

This. Most people still incorrectly concentrate on sequential read/write times. SSDs are only about 4x faster by that metric - 550 MB/s vs 125-150 MB/s.

Where SSDs really shine are the small, rapid read/writes. If you look at the 4k r/w benchmarks, a good SSD will top 50 MB/s 4k speeds, and over 300 MB/s with NCQ. A good HDD is only about 1.5 MB/s, and maybe 2 MB/s with NCQ because of seek latency - the head needs to be physically moved between each 4k sector. That 100-fold difference is what makes SSDs so much faster in regular use, not the sequential r/w speeds.

We've shown Americans how we deal with leakers by our handling of Bradley/Chelsea Manning. Snowden had no choice but to go to our enemies for asylum.

Please don't compare Manning to Snowden. Manning copied everything he could get his hands on and released it all without any consideration for whether or not it had a valid reason to be secret. He threw the baby out with the bathwater. Snowden has been careful to release only the things he feels violated the oath he and others took to the U.S. Constitution. One is a vandal. The other is a genuine whistleblower if not a patriot and hero.

For him to be a hypocrite, he'd have to spy on americans. If he has to do propaganda for the Russians to survive, then who cares? It's the Russians' problem, not ours.

I dunno why you think he has to spy on Americans to be a hypocrite. By doing propaganda for the Russians, he is affirming that sometimes you have to compromise your lesser values in order to protect greater ones. That's exactly what he's whistleblowing the U.S. government for doing - compromising Americans' privacy in order to (in their best estimation) protect their safety. If you actually listen to what Feinstein and others who defend these programs are saying, they're not evilly rubbing their hands together while cackling with glee that they're violating the Constitution. They implemented these programs because they genuinely thought the benefit (improved safety for Americans) was worth the cost (warrant-less searches and degradation of privacy).

What differentiates what he's doing IMHO is that if something is written in the Constitution, that kinda implies that it's an uncompromisable value. That you cannot violate Americans' 4th Amendment rights even if doing so would result in greater safety. Exceptions can be made during martial law and war, but no such declarations were made (unless you consider the war on terrorism to be a real, declared, and unending war).

1. Kids shoot up schools. Why schools? Why not shopping malls before Christmas or movie theaters during blockbuster premiers?

1) Kids are in school 30%-40% of their waking lives. It's normal that a disproportionate amount of everything that happens to them happens at school.

2) They don't really shoot up schools. Statistically a kid is much more likely to be shot outside of school than in school. It's just that "school shootings" have become a thing for the media, so the threshold at which one will become a national news story is much lower than, say, a bunch of gang members shooting each other in a drive-by shooting, or a bunch of teens being killed in a car accident. Despite the impression you get from the media, if you want your kids to be safe from shootings, you're better off sending them to school. Normalize for the time they spend in school (#1 above) and statistically they're even safer.

3) When a shooting happens at a school, the vast majority of victims are other kids simply because of the demographics of the people in the area. So it gets classified as kids shooting kids. When a shooting happens outside of a school, the majority of victims are adults. So it gets classified as a "regular" shooting incident even if a significant number of kids were victims

This is just the flip side of Windows RT. Microsoft developed RT to hedge their bets. If the market stayed with x86, they could sell regular Windows. If the market switched to ARM, they could sell Windows RT. RT didn't need to be successful, it just needed to be there.

Now Intel is doing the same - they're hedging their bets. If the market stays with Windows, they can can sell CPUs for Windows machines. If the market switches to Android or whatever OS over Windows, then can sell CPUs for those machines.

That's really what the phrase "Wintel is dead" means. It doesn't mean there are no more Wintel boxes being made. It means the Microsoft-Intel partnership is no longer an exclusive partnership as if they were one company. They're starting to treat each other as just another disposable business partner.

This. The tablet was held back for nearly a decade by Intel and Microsoft insisting that it had to be a convertible laptop. Microsoft wanted to make sure each tablet sales was a Windows license sale, and Office too if they could. Intel wanted to make sure each tablet sale was was an x86 CPU sale, and a high-end CPU too if they could. Consequently, the tablet PC market stagnated at fewer than 100,000 sales per year for close to a decade.

The real technology that led up to tablet market space wasn't the smartphone; it was the netbook. Suddenly people realized that most of the stuff they did on laptops (email, web browsing, myspace/facebook, listening to music, watching movies), they could do just fine on devices which didn't run Windows and didn't have a PC-like CPU, and consequently could be cheaper than a laptop, not more expensive like tablet PCs were.

Machines that have broken down will work perfectly when the repairman arrives.
