My first job out of college was for a fabless semiconductor company in Southern California. We had a small (~20 racks) data center in the ground floor of the building, and I was involved in its design & operation.

Top-level execs had made the decision to not get a backup generator. The one compensation was that we got a manual transfer switch, so that we could easily truck in a generator & cooling in case of a planned outage. There was the possibility that we'd be moving at some point, so self-containinment was a big thing.

Taking that into account, I suggested getting an Eaton 9390 UPS, with two IBC-L battery cabinets and an IDC breaker/distribution cabinet. (http://lit.powerware.com/ll_download.asp?file=Eaton9390UPSBr...) The distribution cabinet outputs went to in-rack Eaton RPMs (http://powerquality.eaton.com/Products-services/Power-Distri...), and from there to PDUs.

This setup gave us ~45 minutes runtime at normal load, and more if we shut down non-prod. The one time we had an outage (during my tenure there), shutting down non-prod allowed us to ride the outage. I also liked this setup because our only connections to the outside (power-wise) were from the fused disconnect input, and the EPO. In the end, the "single-line drawing" looked like this:

Building fused disconnect-->Manual Transfer-->IDC cabinet breakers-->UPS-->IDC cabinet-->Rack-->PDUs
Outside Generator Hookup---> Switch (input/bypass) dist. panel RPMs

Everything after the Manual Transfer Switch was either internal to the UPS, inside the racks, or in flexible conduit. I loved it so much!

Unfortunately, the electrical engineer hasn't seen such a thing before. In the past, the 480/208 transformer was external to the UPS, and this is what the electrical engineer was used to. So, the engineer wrote up plans to run an electrical duct from the UPS, to the Manual Transfer Switch, and then on to the transformer (in other words, back to the UPS).

I totally missed this mistake on the plans. It was actually caught by the construction crew, who was laying out the ductwork and realized that something looked weird.

In the end, one of the conduits was used, and the other one was just left in place. Luckily our connections from the IDC distribution panel to the RPMs were flexible, because that second conduit got in the way of pretty much everything.
That is exactly what I see too.
Not the OP, but that's certainly including regular maintenance.

To use a previous example, replacing the fan belt is regular maintenance. The problem is that Audis are very tightly engineered. Good in some response, but not for easy maintenance/repair.
This makes me wonder if anyone has implemented diff by comparing the Abstract Syntax Trees of the two code-bases. I guess it's probably easier than regular diff (assuming you've already got the ASTs from somewhere).

>We've had not one but several nuclear disasters in the past several decades and in each case the sky hasn't come crashing down.

Unless of course you're one of the people who lived in the nuclear exclusion zones created by Chernobyl and Fukushima, in which case, yes, everything you own and possess, very potentially including your long-term health, were destroyed in a matter of hours. Those residents can never go back for more than a quick temporary visit, and they can not take back their belongings because they've been irradiated. They will always be asking themselves if they got enough of a dose of radiation to cause early disease.

Call that localized and controllable all you want, and if you propose building these plants in areas with no nearby inhabitants for many sq miles, maybe it works OK. The current system, where we say "Don't worry, it's all perfectly safe, we double-pinkie-promise that we won't make the mistakes those guys in Ukraine or Japan made, and if you disagree you're an idiot who hates science" is just not going to fly.

This is not general alarmism about being unable to mitigate every risk in life. This is a comparative analysis of the potential risk profiles of fossil fuels and nuclear, and fossil fuels being much better because the cost of a catastrophic non-nuclear failure is much smaller than the cost of a catastrophic nuclear failure.
Right, so make my cost $15 and pay the driver $25 and Uber still loses $15. I'm okay with that if that means I and the driver don't have to stress out about the tip before each ride. I don't want to be responsible for the driver making living wage when I don't employ him.

If Uber does this and they realize customers are not riding as much anymore, then it is a problem with their pricing and setting of expectation.
hey, i'm the OP and would love to discuss / answer any questions

Ask HN: Why aren't Comcast and AT&T stock prices up, with the new privacy rules?
Was this development known to sophisticated traders, and already priced into the stock? CMCSA spiked in early November (both before and after the election) and T spiked in November as well (several days after the election).

I would have thought that the new law would open up a large revenue stream for these companies, which would have sent their stock price up. Is the revenue opportunity not that large, or did all the big players already see this coming?
I checked out twoemproxy because it seemed interesting and noticed a few things:

* the last code commit was 8 months ago (and was very minor)

* there are 120 open issues

* it's written in C

Now this is far from abandaomware (imo), but it still seemed like a risky dependency to lean on. Have you guys moved past it already? Any thoughts on the cost-benefit analysis there or alternative solutions?

Note: I mention C like a detriment because I myself cannot write production C and therefore would think twice to using a library/service I myself could not fork (and probably many other devs).

Uh, Britain organised a full blown referendum for Scotland after Scots voted a separatist party into their own local Parliament ... a referendum the nationalists then lost. Now perhaps there'll even be a second, despite said nationalists saying it would be a "once in a generation" event.

> the same thing (externalising the cost of their downsides) happens with nuclear energy. / So if anything, they're equally terrible in that regard.

That isn't true. There are externalities for both, but the externalities for carbon are far greater. The above statement is like saying: No houses are free to buy; therefore all houses are equally costly.
That's an oversimplification of the Third-Party Doctrine, particularly as applied today.
Great article. Was not aware there is this much stigma around tantalum caps. There are times when I am forced to avoid ceramic caps for better high frequency handling. It looks like polymer is the way to go - better longevity and no ethical issues.
While not 100% 'free market,' I think that turning things like last mile lines, etc in to a public utility (allowing many ISPs to hook into them), and abolishing local government-granted monopolies is the real solution here. While abolishing the government-grants of monopoly status is unquestionably free-market, turning the last-mile lines into a public utility is slightly less so. But this move would effectively force the playing field to level a bit.

If you wanted to make it slightly less "government-y," you could just establish rules that those running the last-mile lines, and those providing the connectivity must be separate entities (and not connected to each other like some "spin it off as a separate division of Comcast but they are still parts of / owned by the same company"-type deal) so that everyone gets a fair shake.

[ That said, I'm not in favour of letting the privacy war play out in the market, because I'm not 100% sure that the market wouldn't just settle into a state where everyone was doing something I don't like to some extent. ]

Humans can also work fine with almost no brain tissue, as has been discovered throughout history. The canonical article is from 1980, "Is Your Brain Really Necessary?"[0]

"There's a young student at this university," says Lorber, "who has an IQ of 126, has gained a first-class honors degree in mathematics, and is socially completely normal. And yet the boy has virtually no brain." The student's physician at the university noticed that the youth had a slightly larger than normal head, and so referred him to Lorber, simply out of interest. "When we did a brain
scan on him," Lorber recalls, "we saw that instead of the normal 4.5-centimeter thickness of brain tissue between the
ventricles and the cortical surface, there was just a thin layer of mantle measuring a millimeter or so. His cranium is filled mainly with cerebrospinal fluid."

I can think of many situations where this wouldn't be the case. Poor women in states with restricted access to abortion (requiring multiple visits to a clinic that's hundreds of miles away for example); women trapped in controlling relationships where leaving could be physically risky; teens who get pregnant for socially immature reasons and end up not wanting the child.
I think the syntax is a lot of ideas under the original idea of the C language. Without the original idea of C as a foundational language there would be no reason to create the syntax for C. So I'm really not sure where the value lies......Which is why I asked :))

Sounds like an indirect way to say you want to privatize social services. If a country is "selling" you a social safety net, you're essentially just paying a company for insurance coverage and/or a retirement savings plan.

Agreed, and we should add the far greater costs of climate change.
Check out the CDC stats. Teenagers today are actually abstaining from sex at higher rates then ever before and the teen pregnancy rate has dropped by HALF over the course of the last 25 years. So tell me about the other magical time where there was more "self-control, discipline, and tradition" among teenagers than now?

By the way, we've been controlling our fertility since the sexual revolution which started around half a century ago. Since our society hasn't collapsed in 50 years I can assume additional and safer options to control our fertility won't bring a collapse.

Would you consider making your addon code available? I am very interested in this.
I'm sorry, but that's ridiculous. I can't fathom a parent who would go through the effort of getting their child on birth control, but not having a discussion about STDs and safe sex.

"Kids" are going to have sex, we should take every opportunity to provide them with a means to do it as safely as possible.
I'm sure it does, but doesn't Westinghouse go way back, to the start of the electric era? Didn't they built it, or lease most of it?
I shows that there is not actually a consensus like we've been told.
> Although some minority of people derive "meaning" from work per se (work = something that you get paid to do), I would say that the vast majority of people can derive meaning from other things. For the vast majority, work is for getting money.

I think it may be possible that you could be conflating two subtly different things here. Where people currently derive meaning in their lives might not be quite the same as where people have the potential to derive meaning in their lives.

I know a number of people who are, for instance, psychologists, teachers, or social workers. They have chosen to derive meaning in their lives through work. Some of them have also gone on to raise families and care for others, turning sources of potential meaning into sources of active meaning. Thus people can incorporate both current and potential sources of meaning into their lives. Some people opt to dedicate their lives entirely to their current sources of meaning!

Yet, it's perhaps less than maximally wise to conflate someone seeking meaning through their work today with their future in which they might seek meaning through raising children. Meaning does not always operate with expected values.
My understanding is that the plant was built seaside to make use of the ocean water for cooling. There are definitely alternatives to this, but in the cost analysis, how many other tradeoffs re: the expediency and safety of nuclear technology are we making that are going to prove to have been in the wrong direction? What is the failure cost going to be?
What are you trying to achieve here? Make them rewrite the whole project from scratch? You made your point clear in your first reply.
Thanks for reaction.
I think so too. But other vdom implementaion is more bad things,

Actually the biggest problem at this point is that measures to detect hacking of any kind are severely lacking.

>All it would honestly take is a requirement that all voting machines print out a receipt of the vote. Then you could drop that into a box on your way out, and someone counts those votes to make sure they line up with what the database says the final vote was.

That would work, but sounds like a very expensive way to achieve the same level of functionality as a red pencil.
Here you can see the problem of these congressional committees: they hear from a few people on one side, and a few people on the other, completely unaware that the few denialists they've heard from are basically all of them (Curry and Christy are pretty infamous), whereas almost every other scientist disagrees. They should have to sit through 97 witnesses who agree with the consensus for every 3 who do not- that is the only way to really understand it.

You cannot challenge science with teams. Science can only be challenged with evidence.

"Prominent scientists operating outside the scientific consensus on climate change."

That's already a red flag.

Prominent scientists have, and will continue to challenge climate change from within "the scientific consensus" (whatever that is suppose to mean -- consensus is irrelevant).

Climate change is true not because of a lack of challengers. It is true because we have only found evidence to support it. It is true because of a consensus of evidence.

The nature of climate change is highly debatable (= could use more research and hypotheses) and uncertain (= further understanding is possible). But we cannot get into "the nature of" while in denial of "the existence of".
It's the drive for personal growth, known as "self-actualization". It's an interesting topic to think about, assuming an AI order of magnitudes more evolved than a human brain, what would its drives and motivations look like.

Oh nonsense. If enough people change their minds there will be another referendum or some crisis meetings. 'We can't stop it now,' is self-destructive rationalization.
Right now waste can and should be recycled which would reduce the amount of waste. https://en.wikipedia.org/wiki/Radioactive_waste

Soon it will be possible to use most of the waste as fuel:

"...Fast reactors can "burn" long lasting nuclear transuranic waste (TRU) waste components (actinides: reactor-grade plutonium and minor actinides), turning liabilities into assets. Another major waste component, fission products (FP), would stabilize at a lower level of radioactivity than the original natural uranium ore it was attained from in two to four centuries, rather than tens of thousands of years"

http://en.wikipedia.org/wiki/Integral_fast_reactor

How does coal waste compare to that?

"Coal ash – the waste material left after coal is burned – contains arsenic, mercury, lead, and over a dozen other heavy metals, many of them toxic."

http://www.psr.org/environment-and-health/code-black/coal-as...

"The study found that levels of radioactivity in the ash were up to five times higher than in normal soil,"

https://phys.org/news/2015-09-radioactive-contaminants-coal-...

How much coal waste is produced per year?

"According to the American Coal Ash Association's Coal Combustion Product Production & Use Survey Report, nearly 130 million tons of coal ash was generated in 2014."

If this your contention, then you immediately want to stop all coal and oil plants pending regulatory overhaul.

You have a rather large flaw in your logic.

The statement that you are quoting is directly supported by the data in my link. Fatality rates in the US are generally an order of magnitude lower than in the rest of the world, because of US regulations. This is a statement of fact, and not an argument for any random regulations that you just thought up.

On your statement about radioactivity, coal plants distribute more radioactive material than nuclear, but nuclear produces more nasty waste per gigawatt than coal. So far nuclear has been astoundingly safe, but the eventual damage from nuclear depends on our ability to safely store that waste for longer than human history.

There most be an increasing amount of hardware/software with egregious business value (hundred million+) with a decreasing number of surviving/available designers etc. Rationally if these people were required to fix or maintain such systems their yearly value would be in the millions wouldn't it?

For some reason I get the feeling that such people are not paid in the millions. Maybe double or triple a traditional salary but not in the executive-bonus tier. Do they deserve to be?
Are they equally weighted maybe? As one does not live without the other?
VPNs are one solution, it may even be the only possible solution, but I really can't see it as a good solution.

It is super important to keep in mind of course that there may indeed be no good solution, or it may be that the good solution is politically, economically or otherwise unfeasible. In this case a good solution is technically very feasible, but that may often not be the case.
If there are too many examples to get into, please share a few.

I understand what you are stating, I see it like this;

You could program a computer to 'understand' better and worse Go play, then you start it up and have it play both Go programs and human players on the Internet and it would get better over time until no one could beat it.

Alternatively you write a program to predict the 'next' move in a Go game, and you process through it a million previously played games to tune its probability weights.

The latter is 'machine learning' the former is 'programming' but I assert they are both programming, just using a different compilation tool chain.

This cost would be much easier to calculate if every country reprocessed spent nuclear fuel like France does instead of storing it. Reprocessed MOX fuel costs almost ten times as much as enriched uranium, but the left over waste products decay to levels similar to natural uranium in 300 years instead of 10,000. Molten Salt reactors would probably make reprocessing cheaper.
