Raw material supply is a big issue; see Berkeley physicist Tom Murphy's calculations: http://physics.ucsd.edu/do-the-math/2011/08/nation-sized-bat...

He's mainly talking about lead but for lithium it's even worse.

A lot of things look great until you look at the scaling limits. Hydro storage is another example; Murphy's got a post on that too.
Prior work in CompSci on various engineering techniques showed code review to be among most effective at any part of lifecycle. Testing can miss lots of things. So, best to do both.
I guess it could drive itself home after dropping its owner off at work, but that's probably too inefficient in most cases to make a full extra round-trip just to charge up with the panels at home.
Philosophy has been tackling this issue forever. And, in my opinion, plenty of brilliant minds have provided excellent cases throughout philosophical history that make it clear we most certainly do not have free will. Oh, we certainly love to feel and think that we do. Primarily, this provides us a sense of control over our lives, over the space we inhabit across a given time period. We also love to punish others as if they did, as free will is the foundation of determining and adjudicating moral responsibility for one's actions. But that's more a reflection of how we want to see the world operating according or in opposition to our whims or, as the article puts it, a product of tricks our brains play on us that helps us feel like we have control.

The problem is we have no satisfactorily logical and coherent case for explaining how a human agent exerts controlling causality on itself and the space around it through time. Because of this, most attempts at defending/arguing the existence of free will typically hinges on altering the definition of freedom that must be obtained in willing, an effort to carve out a defensible position that looks like free will, but is a rather amusing game of endlessly moving the goal posts toward a compatible definition of freedom.

For compatibilists, this pretty much always turns into a logical playground of arguing that being able to do otherwise would be the case if some increasingly creative number of things about oneself had been different. Peter van Inwagen's replays-by-god are a pretty amusing example here. Compatibilists accept causal determinism outside the human agent, but seek to carve out a space within for the human agent to will and act freely.[1]

Incompatibilists, naturally, reject the notion that freedom and causal determination can co-exist. So they typically argue over a number of varying-strength propositions that seem to more often accept agent freedom as a given, but causality as the thing worth arguing over.

For some time yet, I imagine we will continue to argue over and shift the lines of where the human will may be considered the causal source of human action. But I don't think we're ever likely to come up with a definitive argument that is intelligible enough to be satisfactory.[2]

---

[1]: There are, of course, some who like to differentiate between acting and willing freely, of course.

[2]: I can't help but wonder where this conversation would be if we hadn't had many intervening centuries of religious dominance in various human endeavors, including philosophy, that sent us on centuries of building gods into our arguments, and then subsequently taking gods back out and winding up nowhere closer to a decision. Well, maybe a bit closer, but we're still dealing with the implications of gods on human will and action in the 21st century.
I thought I read that some water districts run their pumps at reduced volume during peak hours and top them off before or after. It's a smaller volume but it's already a solved problem.

And it allows you to push some levers and dials as to whether it's cheaper this year to increase your water capacity or your power capacity. City planners love that kind of thing.
Except everyone involved in Bitcoin's creation was aware of about 20 years of precedent and discussion about these kinds of issues -- http://cypherpunks.venona.com/ -- so it wasn't really hindsight

Before IAM, the issue I had with service accounts is that I forgot to give the account Edit permissions. It seems the new way is like how @i_have_to_speak mentioned to use service account for an instance, which can only be done during creation of the instance, if you don't want to distribute keys. Then the newest way, that's still in beta, is to use IAM roles to further restrict the access scopes of that instance service account.
You have to do a multi-step transition

1. Add new database structure (new columns, new tables, whatever) but leave all the old structure in place

2. Update all servers with code that writes in the new format but understands how to read both the new and old structures

3. Migrate the data that only exists in the old structure

4. Get rid of the old stuff from the database

5. Get rid of the code that is responsible for reading the old format

Conceptually it's straightforward but it can take a long time in calendar days depending on your deployment schedule, it can be tough to keep track of what's been migrated, and the data migration will cause performance issues if you don't plan it properly (e.g. trying to do a migration that locks an important table). You just have do it in a way where each individual change is backward compatible and you don't move on to the next change until the previous one is rolled out everywhere.
I do wonder if the job-for-life culture in Japan helps with this. Perhaps, rather than people being lazy because they can get away with it, not being terrified of losing your job means they can actually appreciate it, and learn to take pride in their work.
I went through Apple's DMCA requests sent to Github and the only one that is remotely similar is this:

https://github.com/github/dmca/blob/master/2014-11-04-Apple....

But even then they weren't claiming it was reverse engineered material, but instead material ripped directly from Apple's copyrighted and confidential docs. I think both Apple and Github understand the boundaries of the DMCA pretty well. According to Github they haven't attempted to take down any of the following:

The process command interface is more structured! You don't have to go through /bin/sh and worry about escaping. You could call exec. Ok, so you'd still have to worry about sticking "--" before the URL, but that's easy. No more worries about quoting.

Of course, chaining multiple commands together is a pain, and that's what the shell is good at, but then it is hard to get the quoting right. So a more structured shell interface. There's libpipeline, but I haven't used it to comment on.
CCs are the easiest to fix in this case

I'm not talking about the vulnerability that this kid found. I'm talking about vulnerabilities that would allow access deep into the Facebook infrastructure. I think there are in fact some vulnerabilities the NSA would be willing to pay more than $10k for if it would allow them long term access to a lot of sensitive Facebook data.
What an incredible moment in the history of a major political party in the US. Trump is the man for the GOP, and it's hard not to imagine that it doesn't mark the beginning of the end of the GOP in some form, in the long run.
As far as I can tell LSTM's are still using a combination of logistic and tanh transfer functions, at least through 2014 and some of the most impressive deep learning results have been obtained with these.

He has yet to deny it.

Also, Carly Fiorina is now the shortest lived VP candidate in history.
> the idea that everyone in Brazil can be denied the freedom to communicate the way they want is very scary in a democracy

If companies like Facebook were not funneling everybody onto centralized platforms, it would be harder for an ISP to deny that freedom.

The centralization of communication platforms is a bigger problem than any ISP censorship. That they have a target to shutdown at all is the real issue.
Why is this interesting? It looks like any other Xcode update.
I agree with pcwalton, that's how I read it too. The context of this thread is security vulnerabilities in OpenSSL, so it's quite reasonable to read your parent comment exactly as pcwalton did.
Hello President Trump!
Why would you say it's the beginning of the end? Maybe it's the beginning of a descent to a darker time pre-Civil Rights, where the Trumpian ideology is mainstream.
The next few months are going to be interesting.
Sorry for the noob question, but isn't there always sun somewhere on the planet? Are electricity grids not globally connected, or would it be lost in transmission?
GOP has been selling "Washington establishment/insiders" hate-story to its electorate for a bunch of years, and finally that electorate bought it. One reaps what the one sows. Or something about the cake.

The essential takeaway will be that the current focus is on cortical algorithms representing the neocortex. Even as such, the current models are only partially inspired.

From there, something might stand out to you.
Caution : This is the harder and unpaved road.

Neuroscience.
Neurobiology.
Computational Neuroscience.
Information theory.

For conversion work to computational land, a creative mind and a broad array of knowledge and experience in software engineering. Might take years but you'll maintain a depth of understanding and much greater capability of tackling AGI.

On AGI efforts, I personally can't imagine how one can maintain they are on a path to AGI by way of instantiating an artificial form of it yet have not even a basic understanding of how the biological form of it functions or how far off their models are from the essential parts that make it tick.

I guess to some people, it's cortex all the way down.
So it's not at all about privacy?

That's interesting. But it makes sense, I suppose.

It's just the vocal minority that push privacy in WhatsApp. But it is good to see Facebook supporting private communication. Apple and Facebook, who would have thought?
Why would you say it's the beginning of a descent to a darker time pre-civil rights? What has Trump said that makes you think he will take away civil rights? Have you considered that a huge number of Americans have effectively spoken as he becomes the nominee?
You are perfectly fine regulating the tax side, even in most socialist European countries there are no pay caps.
That one needs manual seeding too, which may lead to more issues.
It won't end the GOP. At worst they will spend another 8 years outside the whitehouse, while a disgruntled population also throws them out of congress.

The bug/feature of a two party system is that ~40% of the population (the non-swing voters) have no alternative to the GOP.

Sigh, I lost some money on betting Trump would not being the nominee (so take my political acumen with a grain of salt)
This talk about C++ and rand being harmful is quite educational: https://channel9.msdn.com/Events/GoingNative/2013/rand-Consi...

What it points out is that even a good random number generator can be used incorrectly, and without the right tools your efforts to produce truly random numbers are doomed from the start.

C++ has an embarrassing wealth of random number generators. The Ruby core has almost nothing that can measure up to that, yet it seems like a huge oversight.

I like that C++ has a generator for many different use cases, they all have their reason for being there, but Ruby has a singular one with unknown properties. Porting over what C++ has and making a proper Random library for Ruby would make a lot of sense here.

They are not globally connected. And losses become significant after a thousand kms or so. You're not going to get to the electricity to the other side of the world where the sun is shining.

You need local storage. As much as is said about batteries, the only real solution here is hydro. Expect to see every viable valley start to get dammed over the next decade or so.
Wow. A testament to focus on quality that is.
Leading news orgs still report on Trump, so that's a low bar ;) I'd recommend looking at people who actually tried to dissect and reproduce the proof instead.
Wait, really ending for good, so he can't be nominated? What about all the party/convention rules shenanigans they can do, where they can still nominate anyone who won delegates? Was that a misconception? Or just the Democratic Party?
You couldn't do one with some different tables? What was justification for both separate DB's and the Q&D/meta split? Just curious.
But images and videos are byte streams already... The security boundary is often the network, where things are serialized anyway. The whole point is to sandbox the deserialization only, which has a large attack surface due to complex conditionals and string handling.

The rest of the application will need to run with privileges to actually do the stuff you care about, like display things to your screen and so forth.

Supposedly you see the same drop in crime after lead was phased out of gasoline:

http://www.motherjones.com/environment/2016/02/lead-exposure...

> That tip took Nevin in a different direction. The biggest source of lead in the postwar era, it turns out, wasn't paint. It was leaded gasoline. And if you chart the rise and fall of atmospheric lead caused by the rise and fall of leaded gasoline consumption, you get a pretty simple upside-down U: Lead emissions from tailpipes rose steadily from the early '40s through the early '70s, nearly quadrupling over that period. Then, as unleaded gasoline began to replace leaded gasoline, emissions plummeted.

> Intriguingly, violent crime rates followed the same upside-down U pattern. The only thing different was the time period: Crime rates rose dramatically in the '60s through the '80s, and then began dropping steadily starting in the early '90s. The two curves looked eerily identical, but were offset by about 20 years.

> So Nevin dove in further, digging up detailed data on lead emissions and crime rates to see if the similarity of the curves was as good as it seemed. It turned out to be even better: In a 2000 paper (PDF) he concluded that if you add a lag time of 23 years, lead emissions from automobiles explain 90 percent of the variation in violent crime in America. Toddlers who ingested high levels of lead in the '40s and '50s really were more likely to become violent criminals in the '60s, '70s, and '80s.

> And with that we have our molecule: tetraethyl lead, the gasoline additive invented by General Motors in the 1920s to prevent knocking and pinging in high-performance engines. As auto sales boomed after World War II, and drivers in powerful new cars increasingly asked service station attendants to "fill 'er up with ethyl," they were unwittingly creating a crime wave two decades later.

True, I don't know what I was thinking when I wrote that.

Correlation between two variables, does not imply one causes the other.[1]

The Republican party is the minority party, only ~29% of the population identify as such. A smaller % is actually registered, and a small percent of that (< 30%) actually vote in primaries. I would confidently say that a "huge" number of Americans did not choose Trump.
As a small thing, the site returns a server error if you enter >=$1350. It may be that there are very few people searching in that range, and you're not really worried about it. If it were me, I'd link to your most expensive build (the one for $1350) and then give a small message suggesting where extra money can be spend (SLI, crazy case, more HDD, RAM disk, etc.)

Edit: Now that I see the 'improve' and 'cheaper' buttons, and that they let you exceed $1340 if you manually 'improve' components, I'd be more concerned about the server error. Also, to make the 'improve' and 'cheaper' buttons more obvious, I'd put a prominent banner right above the build you return, where you point that function out to the user.
Up next: Hillary.
How is this even remotely good science? So far as I can tell, they didn't admit the possibility that this can be either complete noise (if you have, say 100 diseases, and you're looking for time-series correlations, or performing tests with too low an alpha or power) or caused by a confounder.

The task of making causal claims is a difficult one, and not one to be made lightly. The literature is replete with examples of this going terribly wrong, even with perceived physical justifications. See

"there's a healthy risk aversion and lead times favor good practice."

Well, that's good. The lead times being an enabler for software QA is a good thing to remember. The "release early, release often" companies might be harder to get onboard with QA. Don't need glacial cycles but at least a few months to work out bugs on significant features.

It's funny, though, now that Retina is a thing, how much superior OS X font rendering algorithm is. This was not very clear when fuzzy low res displays were the norm.

> in violent agreement.

Violent agreements are lovely when they're sorted out by the market: at the moment, the best engineering talent I know would not be caught dead working on (just as an example) PHP.

There's simply no need to let your skills and salary stagnate when you can get paid more for working with the state of the art elsewhere.

Demand is simply too high, and like anything, there's tradeoffs: you can get anyone to do anything for enough money. But "great talent," "cheap," "low autonomy," "fossilized tools," will require some compromise.
Around 1900, the "tin" in tin cans contained about 12% lead, which leached into fruits and vegetables. You have to wonder if there's any way of correcting for that. [Source: "The Great A&P" by Marc Levinson, page 50.][Edit: read the paper cited and they make no mention of this]
