The worst I've seen has been in Johannesburg in South Africa, where automatic transmission is rare. I used to refer to it as concertina traffic before I knew it was called a traffic wave, and the concertina is a popular instrument in South Africa amongst the ancestors of the people who are usually responsible for these waves.
Agreed, and that's what he said, the cooling was for humans, not the servers. I think their current plans are open where they let air in from outside.
We sleep in cycles which last about 90 minutes each. Assuming it takes you around 15-20 minutes to go to sleep you wake up at the end of a sleep cycle and don't feel drowsy. What also helps is going to sleep at the same hour every day, like in your case.

I did the exact same thing as you, I would always go to bed at 11.30 PM every day and wake up at 6AM. After a while I'd wake up a minute or two before the alarm went off.
We can see today that the automotive industry is receptive to regulation, even at the expense of competitive edge, when the thing being optimized for is in the name of safety. I imagine that even if there is a pattern of the sort you describe, it will be limited to the adolescence of the whole thing.

If we get sufficiently far out (decades in, after human-driven cars are completely gone, not just out of obsolescence, but due to being outlawed at least for certain areas), I'd bet that what we'd see are demands for compliance that resemble the restrictions on automakers that we have now. I imagine that the driving programs would eventually be in the hands of some regulatory agency, with municipalities being allowed some control of the parameters.
Indeed, but it is critical to me (and I think I'm not the only one in academia for which it is so) that it uses the arXiv funding model -- donations to be sustainable -- and not the Github/Authorea model, where you pay for each private paper/repository you set up.

---

It is interesting to note that as a programmer, I do not have that many issues with releasing partial or incomplete source code on Github, whereas as a computer scientist, I do not like to release partial or incomplete proofs at all.

It might be because the academic community cares about reputation: if you get a reputation as a researcher that releases incorrect proofs, your career is over. In programming, as the names are attached to project much more loosely, such negative reputation is rare and people care much less.

I second that and after if you are keen it can be good to look at the Feynman Lectures vol III, Chapter 5 where he talks about spin. He deliberately leaves spin out of QED to keep things simple. Also if curious there's the Feynman lectures on Gravitation where he tries to figure out quantum gravity and fails like everyone else. One thing I like about Feynman is his talks are based on experiments - if you fire electrons at two slits this happens (QED) or if you send them past a magnet that happens (Ch 5). This is in contrast to most popular science books which go on about spooky cats or most academic treatments which launch into a bunch of abstract maths without looking that much at what's going on physically. I find it much easier to get my head around the real experiment approach.

On your second point, no, a 1000W heater will emit the same amount of heat (neglecting visible light losses, which, as other commenters point out, will be converted into heat later on) as a 1000W computer. This is the first law of thermodynamics, and the fact that the computer is doing computation makes no difference.
I think they will. They shipped "Hitachi" drives for awhile, but now are branding them Toshiba. I think the same thing will happen with OCZ-- they introduce a Toshiba branded drive, that's exactly the same as the OCZ and over time make these more available than the OCZ branded ones until the market has transitioned.

No. Energy in a closed system is constant, so if a computer uses 1000W and stays itself at a constant temperature, it releases 1000W as heat.

No, the point is that usually fitting things in RAM lowers the budget. So it's well worth doing proper analysis on whether or not you can (a) fit all your data in RAM and (b) if a cluster of machines does not become it's own reason for existence.

Replacing a large number of nodes with a single machine with a lot of RAM is usually a cost savings measure rather than a larger expense (and it saves power too!), and due to a lack of communications overhead and exploitation of the fact that you now have access to all the data in one go you may very well find that your algorithms run much faster.

A distributed solution should be a means of last resort.

That's the point of the tool! To remind people to compare the cost of fitting the data in ram compared to the cost of not putting it in ram.
So these scammers are going to get out of it with just a little scratch after decades of doing this and making 100s of millions:

The younger Reynolds’ settlement will be suspended when he pays $75,000, the FTC says, and Perkins’ settlement will be suspended entirely “based on her inability to pay,” unless authorities discover they lied about their assets. Effler’s will be suspended after he pays $60,000.

Looks like all those cancer walks and runs are pretty good venues for these scammers to get piece of action. Normally, when you are donating you will look up charity's ratings but in those events people rarely look them up because marketing is so strong that everything looks in order. Even $100 a piece for few hundred people every week in some city can rack up large sums in well advertized events. They now even have "professional fundraiser" which means this must be a booming business already and FTC has barely scratched the surface.

I believe it's more "no, you don't need an Hadoop cluster of 20 machines, your data fits in the RAM of one machine".
What about the energy conservation. Of course there are energy leaks in AC->DC conversion if you don't take into account the heat produced during the conversion. If your purpose is heat, the efficiency is 100%.

A radiator behaves like a very big passive cooler for your data center. You want it to be less than 60°C to avoid getting burned. That is perfect for CPU. Fans are definitely far from mandatory.
Right, RAM an order of magnitude faster than disk, so calculations will be performed very quickly. Big data usually implies clusters of servers because the data won't fit on one server (even on the disk).
There is no point deploying a heavy, complex (and usually pretty slow due to the overheads involved) distributed database, when you could just buy a server with xTB ram, load any sql database on it, and run your queries in a fraction of the time. If your data is so large that it can't fit in the RAM of a single machine, then distributed databases make more sense (since loading data off disk is very slow, modulo SSD).
How to determine the right cost of building an App
Regarding the last paragraph from the article, about lock-in: as long as the chosen foundations are strong enough to reason about proofs themselves (as formal objects), it doesn't really matter. For example, suppose mathematics gets locked-in to a proof verifier based on Logic A, and I want to work from Logic B. Rather than prove Theorem T using Logic B, what I can do is prove Theorem T* using Logic A, where T* is the theorem: "Logic B proves Theorem T".
This is actually very interesting. The title is pretty misleading though. I fully expected some site dedicated to sensitive political issues or ethical problems but instead it's about thinking about hard problems or things that are hard to reason about without standard methods.

I'd rather see this kind of thing heating water, which could then be used either for space heating or directly as hot water (in both cases, as input to a conventional boiler, rather than being expected to provide all the heat itself). In places with large seasonal temperature variations, one typically still wants hot water for washing, etc. even when space heating would be undesirable.

To combat seasonal demand, last-mile, and access control issues, I would actually want to see this set up either as a district heating scheme* (e.g. in the large buildings built for mechanical telephone exchanges); or to heat water for municipal or club swimming pools.

Ha, i feel the same way when, for some reason, for work experience I got stuck in the local government road planning department. I was bored out of my brain but I did learn about corner radius for speeds, acceptable road crests, minimum sighting distance for signs at various speeds, acceptable on-ramp lengths and on and on.

And all it ever did was highlight to me how often somene did a crap job. And usually there was always fresh evidence of crashes in the vicinity. The people who crashed were probably told they were bad drivers,m without realising half the problem was that some desk ok key was phoning it in she the road was planned, or the government was too lazy/broke to fix obvious problems.
Yes! As someone who frequently runs memory-intensive algorithms on large(ish) datasets, I have a hard time explaining to many technical people that moving from a single server to a cluster increases complexity and cost by an incredible amount. It affects key decisions like algorithm and language, and generally requires a lot of tweaking.

When a problem becomes big enough, moving to a cluster is absolutely the right decision. Meanwhile, RAM is cheap and follows Moore's Law.
Actually R, Python and Scala are the best languages for data science.

All three have great library support e.g. Spark and are the primary languages for big data.
Less than 6 machines with 1T each ;) (Assuming the 6 will operate only on local data and will never need to communicate in which case you may well end up with more than 6).

But seriously: the price of RAM for servers is now ~10$ / G.

Complexity, sure. But cost? I thought a single 1 TB RAM server is more expensive than 10x 100 GB RAM servers.

And many people don't want to deal with physical hardware. Dealing with physical hardware increases operational complexity too. They want to rent a virtual/cloud server. Which provider allows you to rent a virtual server with 1 TB RAM?

The subtext is that running a fancy distributed system is more exciting and beneficial for ones resume than simply buying a massive bloody server and putting postgres on it, and that people are making tech decisions on this basis.
Right, but the profit from co-generation from 100W of computation has to be at least greater than (cost of generating 100W of DC) - (cost of providing 100W of pure heat).

I was looking at it in the context of bitcoin mining at the time but it's remarkably hard to find computational tasks that both generate good $/FLOP returns and are stable and scalable which is what a scheme like this needs.

No, python-mode works beautifully for me. There are a couple very minor hiccups (I think there's some error with indentation after a method with no `return` statement or some such) but it's not a deal breaker.
10 servers with 100G will use a lot more power and will require distribution of your algorithm right along with your dataset, so instead of 10 server you will probably end up with a pretty high multiple of 10.

Cost follows complexity, even if it's not always immediately obvious.

A 1TB RAM server is more expensive than 10x 100GB RAM servers, but the hardware cost is often small compared to the business and technical cost of getting a solution to scale across a cluster.

Of course, generalizations are always dangerous—the take-home point here is perhaps that before going to a cluster because “that's the way big data is handled,” it's a good idea to do a proper cost-benefit analysis.

Well the ones I found in Germany need you to change the system, as they do not provide heat directly in the rooms, as in the OP, but have a central system (server rack) that heats the whole house/flat and docks onto the existing piping.
"user needs heat but the internet is down and the radiator has nothing to work on, it starts performing dummy equations" - even bitcoin mining is greener than this
I lived in London and used to ride the 9, which at the time was one of the last routemaster buses.

I also learned that the drivers are comfortable in their chair, and they get paid whether they are late or early, whether they take off smoothly or like a jackrabbit, and whether people are crammed in or left waiting on here stop because they weren't quick enough.

In other words, automation has to be a part of any solution, because the drivers do not care.
Big Data usually implies 'big dollars', not necessarily a large amount of data. Simply use some in-efficient algorithm and a datastore with sufficient overhead and you're in Big Data territory.

Re-do the same thing using an optimal algorithm operating on a compact datastructure and you make it look easy, fast and cheap. Of course you're not going to make nearly as much money.
Part of the energy can get transformed into light (mostly infrared) or sound, but unless it goes out by the window, all that energy will bounce until it's absorbed by a the walls and furniture. It's very easy to get 100% electricity to heat conversion if you have not windows.

You get also 100% conversion with a normal lamp or a sound system (unless they are very close to a window). You get all the heating, and the light or music for free.
