There are startups working on the problem, but we've move very little since Jules Vernes' day, when he envisioned a future hydrogen economy. For now, we're up against:

1. Far too few good sites for pumped hydro, the most cost-effective and round-trip efficient, as well as proven, option. Seawater-based pumped hydro exploiting oceans as a lower reservoir and areas of high coastal elevation gain may offer some additional option.

2. Biomass. Which is what coal, oil, and gas are. Simply, not at current scales. Biomass accounting for a few percent of total present energy use might work, but at present (or forecast) energy usage rates, simply not scalable.

3. Batteries face chemical barriers and substrate availability. Most offer only 1/100th the energy storage density of hydrocarbons (by weight or volume). At scales contemplated, lead and lithium are both critically constrained resources. Super-abundant salts, or organic compounds, might work. But you're still left with scale-of-operation.

4. Compressed air energy storage (CAES) is something my buddies at the US National Energy Labs tell me to keep an eye on, though I'm dubious. Boyle's Law and thermal losses through compression and expansion are problematic. But maybe.

5. Fuel synthesis. 50 years of research, no production systems. That worries me. A lot. But the basic science is sound. Problems: energy cost of liquid hydrocarbon fuels increase 80x over current, and your round-trip efficiencies are on the order of 17-22%. Good news is that storage stability is proven for millions of years.

6. Kinetic systems: flywheels. Engineering challenges (precession's a bitch), very low energy densities, very high costs. They're highly responsive, but other than short-term (sub-second to several minutes) of power conditioning, not an option.
> For example, not all evangelicals are young earthers

It was just an example.

> There are plenty of Christians who wouldn't identify as evangelical who also will try to use the words of Jesus to their advantage

Agreed. Used in the context of elections it is clear what the purpose was.

> Belief in God is not the same thing as giving up rationality; which you seem to indicate. That's a common bias a lot of people have.

It is one of the indicators. Most of all it is an indicator that they will probably listen and follow whatever the pastor of the megachurch suggests.

At the end of the day it doesn't matter if I think they are rational or not, but that those in power who need to mobilize their vote need to think. Think of it as getting the lowest bang for your campaign buck. Who do you appeal to? They are a nice group, and it clearly worked!

Obama did the same thing, so I am not really playing for the Democrat's team or anything, liberals can be easily manipulated. Obama campaign for Hope And Change for example was awarded AdAge award.

That's an award given by a marketing agency for best marketing campaigns. Usually given to Apple, Nike, Coke and so on. Well in 2008 Obama got the prize.

> I think your post says more about you than the large group of people you want to stereotype and marginalize.

The fact that that group was used and used by a large lobbying group and that Bush's campaign kind of support my idea though. It is not much of a hypothetical.

Even the most conservative sources and Evangelicals themselves talk about being betrayed and used by Bush. I don't know what other evidence we'd need:

http://www.newrepublic.com/article/121384/jeb-bush-not-favor...

After all the promises and talks about Jesus they are wondering what happens to outlawing abortions, why weren't same sex marriages stopped and so on. That is what they were waiting for based on promises. Instead it was all about handouts to the military industrial complex.

This whole idea and article leave me speechless (sic).

Talking and writing are two different mediums. Never heard of Marshall MacLuhan?

I curse a lot, at home, where I live alone. As soon as I step out the door I talk differently to my neighbors. I also adopt a different voice when I visit my family in another state. And then another when talking to co-workers.

So which of those should I write in?

Try putting "fucking" in the HN search bar. The top article I get is "Fucking Sue Me" with 689 points. Great.

I can't begin to express how irritating it is to read such articles/blog posts with "fucking" all over the text, even thought at home I probably say that word 10-20 times a day. But I'm not writing that for others to read.

And then we have this gem from PG:

"Informal language is the athletic clothing of ideas."

Really? If I talked like that to my friends or co-workers they'd be laughing at me for days.

To "write like I talk" I'd say: "what an arrogant fucking stupid shit statement."

Good bye HN.

I think better advice is to know your message, know your audience, and write appropriately. If you're skilled enough to write flowery prose in the first place, then you're skilled enough to detect the appropriate level and write to it.

For example, there is a world of difference between troubleshooting a user problem verbally, directly in email, or writing a guide for the problem on a wiki. They all take different conversational styles.
Certainly makes it more conversational. If I had a nickle for every time I've heard someone mutter "damn hg"...
I don't know about "write like you talk", precisely, but I've noticed that some very good writing on technical subjects reads like you could give it as a talk, so there's something there about clarity.
I almost didn't submit it because there were no details on what "mathematical equations" were used.

I think the emphasis was (or should have been) on the algorithms developed to work with multiple processors, but there wasn't much info on that either.

"When you connect 100 computers and tell them to solve a system of
equations, I need to break it into 100 pieces and ship each piece to a
computer, and then they need to talk to each other," Farhat said.
"They cannot do this independently."

To confront this well-known problem, Farhat and his team – led by Jari
Toivanen, Radek Tezaur and Philip Avery – collaborated with the ARL
DSRC to craft algorithms to divide these calculations among thousands
of computers.

The team members worked around the clock for three weeks to prepare
their software for the test on Excalibur. When the day came last
month, they had access to a significant chunk of the facility's
101,184 processors to divide slices of their equations, share
information and solve the problem. A mere three minutes later, those
thousands of processors had solved over 10 billion calculations
accurately.

> Corporations aren't monoliths, but that's no excuse for the toxic situations known to fester in pockets of mismanagement. If these situations are inevitable in big companies, we'll have to dissolve big companies to get an ethical industry.

Why can't we take the mechanisms that work for groups of small companies and apply them to divisions of a corporation? It's a recursive structure either way, regardless how you name it, so maybe we could just copy parts of what works from the small world to the big world?

> Ethics should be a higher priority than profit. Companies should focus on having sustainable business models that support their employees while helping their customers, rather than taking advantage of both groups to drive the bottom line.

We'd have to figure out how to run the economy on ethics. So far the term everything is optimized for is measured in dollars. Being nice doesn't pay the rent, doesn't pay for food and doesn't let you send your kids to college. Morality doesn't buy widget parts, doesn't tool factories and doesn't help CEOs get their private jets.

I used to have this sentiment that "money shouldn't be above people, wake up CEOs and managers, be human beings!" but I don't believe anymore that it reflects the true state of the world. The incentive structures are too strong, you can shout in the wind all they want, CEOs and managers and politicians will agree, and things won't change anyway, because we're all in too deep serving Moloch[0]. It's not that people don't care - they just don't have as much agency as they think they do.

That's the reason I think concepts like automation of industry while switching to something UBI-like are important, because relieving the pressure in the system, letting everyone chill the fuck out, seems to be a good way to reduce the amount of suffering we inflict on each other in pursuit of money.

I couldn't disagree with you more on this point. It's a common fallacy to equate political power (Central Committee) with economic persuasion (any private business). No one is forced to deal with Dan Price and his company - it's up to him and his company to offer value and stay competitive to all stakeholders and customers. On the other hand, the Central Committee's edicts are backed by political power. Disobey, go to jail, or worse.

The word "free" in free market capitalism means freedom from political coercion or force.

You've got a really nice landing page.
It is also good to note that what kind of editing your brain does- the standard that people accept for what clear speech is supposed to sound like, what they strive for and hear in their heads- changes over time. There is more than one way to clean up the exact same actual speech stream, and the cultural norms for the correct way to do it shift.

This is made most obvious when comparing dialogue between new and old movies (good ones, anyway- ones that had good popular contemporary reviews; comparing what people at the time considered badly-written stilted dialog tells you nothing). Everybody knows that preferred writing styles change, but movies document the changes in what people consider to be "normal sounding" speech over even relatively short periods of time (a few decades).

Yes, incluinding the maintainer-mode option can be important, which is why this line should be included in configure.ac most of the time when using automake:

AM_MAINTAINER_MODE([enable])

This includes the --disable-maintainer-mode configure option, while leaving maintainer mode on by default which is the traditional behavior you get when you don't include that macro. This shouldn't change any behavior for most projects.

You can change the default to off with the same macro, if that is important; the key point is to include the macro so it can be changed by the automated packaging scripts used in some distributions.

I recommend Autotools Mythbuster[1] for a nice overview of how to use modern versions of autotools, including maintainer mode[2].

Problem there is the 80%+ loss on the uptake side. Direct solar concentration grabs heat. Solar PV is ~17-22% efficient, you're losing the rest.

Storing excess from wind would of course work, though you might choose other options as well. The advantage with direct CSP is you've got the heat and mechanism to start with.

Paul Halmos in How to Write Mathematics says: “A good attitude to the preparation of written mathematical exposition is to pretend that it is spoken.

My comment from yesterdays post on this topic:

If you're willing to hand-wave away certain things as being outside of the "center of the open-source software-release ritual", then you can get a 'yes'.

But in addition to source-distributions mentioned in the essay, which are "too tiny a minority", two other issues are:

1) If you define "git" as "pervasive" then you can declare that git is the solution. In my field, some of the tools are still only accessible via tarball/zip. Two examples are the IUPAC InChI distribution, from http://www.iupac.org/home/publications/e-resources/inchi/dow... , and VMD from http://www.ks.uiuc.edu/Development/Download/download.cgi?Pac... . PyMol, a more popular free software visualization package, is also not developed using git.

2) If you define "open-source software-release" to exclude fee-based free software distribution (perhaps it is also "too tiny a minority"?), then it preferentially excludes certain flavors of 'open-source software'. For example, I write free software, and distribute it for money. A tarball is an easy way to identify the delivery of the contractually obligated product. I can also send it via email, vs. setting up a private git server and getting accounts set up for my customers.

How much free software development is part of the hidden world of non-publicly accessible development? I don't think anyone really knows.

So if your free software baseline assumes "pervasive git", a public development repo, and no cost to access the code, then sure, the answer is a "yes". Until then, it's a "no."

And my examples show that baseline is only a subset of free software development, with no clear idea of how large it is.
This is a big problem in my opinion. I read a blog post recently that kind of discussed it: http://rajlaboratory.blogspot.ca/2013/12/the-over-mathificat...

Wikipedia should be a resource for the average layman, not mathematically mature individuals who comprise the minority.
I'm very sad to see that reflection (or introspection) won't be making an appearance in c++17. Even limited introspection suggested in N3951 (http://woboq.com/blog/reflection-in-cpp-and-qt-moc.html) would be a great boon. Implementing features that would render Qt's preprocessor useless would be a great start and would standardize the tooling around c++ as well as reducing the amount of boilerplate code required to do something as simple as serialization.
Hopefully there is no more maximum length that PATH could be. My last experience was with Windows 7, so maybe a lot has changed since then. Nothing more annoying than having a custom CMD shortcut that loads a script to add things to PATH that got truncated otherwise, and maintaining that script as new programs were installed and wanted to keep adding to PATH.
always felt like the Windows mechanism of having at least one non-ambiguously global place to set environment variables to be super useful to deal with (instead of the ubuntu '/etc/environment/', except when it's '.profile', except when it's '.pam_environment', except when its '.bashrc')

Another issue with GitHub's automated release tarballs is that they do not include submodules. Though, I've also found that submodules are often overlooked when cloning.
Can we get the headline changed? It is not at all accurate - the size of Wikipedia was a largely insignificant point in the judge's reason, as the article clearly states.

Maybe we should stop with the conspiracy theories about corrupt judges for a second and actually consider the legal situation. The judge's job is to rule based on the law, not to use his own judgment or fight for his idea of social justice.

For good reasons, you could only pursue a lawsuit against someone if you have real evidence of wrongdoing - not intuition or "common sense" or anything else. How would you feel if the RIAA could launch lawsuits against any teenager with a fast internet connection, based on a statistical argument and 'common sense' that most teens steal music?
First off cool blog.

But is there a reason why the maintainer of this blog hasn't shared his or her identity? I am very interested in your background. It looks like some of your earlier entries were made when you were in high school. In any case I am very impressed. Sent a few of your articles to my younger siblings to read.
That's some next level anthropomorphism right there. "Slaughter"? "Murder"? Why don't you just call them "Feline Nazi Stormtroopers Baby Killers" and take the hyperbole to 11?

Cat's don't "murder" anything; murder requires cognition and premeditation. They aren't "programmed" in a way that the programming can be changed; they're apex predators and they kill things that are smaller than they are and have for hundreds of thousands of years. It's going to be deeply disturbing to you, I'm sure, but nature, far beyond cats, doesn't really work according to your apparent understanding of "the rules".
"By contrast, researchers estimate that the United States is home at least 15 billion adult land birds. Cats kill about 10 percent of them each year, according to the analysis."

Does that sound right? Cats kill 10% of all adult land birds? It seems high and my skepticism rises as the Washington Post article discusses the extrapolation done by the researchers.

Also unmentioned in the Washington Post is the mix between outdoor cats are feral cats. The Vice article exclusively talks about feral cats. Feral cats are a bigger problem due to feral cats being unneutered (their litters can grow up to kill more birds).

I dunno I guess I need more research to feel really passionately about this one way or another.

In agricultural areas, there's typically a "barn cat" variety that's less domesticated.
The problem is that in these top tech companies you can actually advance because you're good. Yes that means "climbing over others", and of course, it's rather likely that you are not in fact the best.

The alternative is, put kindly, nepotism, put badly Machiavellian political games. You climb up by marrying the spoiled brat daughter of some senior exec and keeping her happy.

I've worked in the middle east, where nearly all companies are government controlled (not "directly" but through family ties) and the whole society falls into the "non-toxic" category according to this article. Nobody will be working 1 minute longer than they strictly have to (except the personal servants - God help those guys). There is absolutely nothing whatsoever you can do to advance (other than the spoiled brat marrying thing). Everyone who doesn't report to you is against you in every social relation you have and people are constantly laying traps for each other, just to gain a leg up in meetings where the higher ups are present. Truly simple projects get denied necessary firewall access just so the security boss could tell your manager that you're over time. You learn to avoid HR and only ever ask them to "make a contract for THIS guy", because if you ask them to find someone only family members will be allowed to interview. Things like that.

Given the choices, I think I'll be taking the "TOXIC" company, thank you. A lot of people tell me I'll change my mind when I turn 50 or so (used to be 40 but that's getting close and (I like to think) I'm still very sure I want to be in the competitive environment.

I also know software but not hardware, but being a part of a local Hackerspace, I often find myself teaching people who know neither. Arduino is godsent for this, especially Uno-sized ones. They're not so big to be intimidating, not small enough to make you worry you break something, and the software ecosystem around it lets you teach someone loops and conditionals while going from blinking LED to driving a robot around.

Shields are also cool as a concept, but I used to avoid them because they could often be as expensive as the board itself. I'm reconsidering now, given how the prices have fallen in the last year or two. Hell, my friend who is super-skilled in electronics started to buy lots of Arduino Ethernets to wire up some sensors in a small factory, because nowadays getting even a few dozens of them is cheaper than bothering with designing and making your own custom board for the task (if you add up the time you spend on designing and debugging).

Git tags (and branches) are mutable. Tarballs technically are, but don't move around as much. Unless someone's being actively malicious, you can be confident that no-one's going to put new code in an old-versioned tarball.
