They are likely also making money by selling the customer's order flow to large institutions/HFT firms who will happily pay significant sums for this. This is something most other retail brokers are also doing and have been doing for a while. The result is that you as the customer are paying indirectly by getting screwed on your fills.

Please don't maintain a blog just to improve your job prospects.

Not that I think it won't work. But it's an arms race, it only helps you until everyone else starts doing it as well. The cost of playing along is that everybody who wants a job needs to spend more time doing something they don't care about, and "has a blog" becomes less valuable as a signal to employers.

...besides, I already have a blog, and I don't want to lose that advantage.

This is a great vision, but without trying to be a jerk, I have to wonder: isn't this just a restatement of what Erlang/OTP has been doing for at least 20 years? I haven't learned the language yet, so it's a serious question.

And if you want "Erlang validation" it's hard to beat WhatsApp's $19B acquisition. (I doubt that Facebook will be releasing any open source Erlang code any time soon!)

So what's the deal? If you believe in the http://www.reactivemanifesto.org/ wouldn't you be better off just biting the bullet and learning http://www.erlang.org/?
I didn't mean to suggest that Montessori wasn't good or that the other systems were better. All I was suggesting was that there are a multitude of student centered learning frameworks (some of which are montessori, waldorf, reggio, and summerhill). I think based on the concepts of differentiation, some of these may be more optimal for certain learners than others.

As much sulfur pollution, that is. (Mostly because ships burn bunker fuel:[1] the residue left over after you refine off the gasoline)

15 ships do not equal the carbon pollution of all the cars in the world.

To me the surprise isn't that the program works, but rather that it is politically possible to implement. Social policies are limited by taxpayers not wanting to give help that is undeserved, nevermind whether it is more cost effective than the alternative.
I agree, but only if you have something interesting or useful to say. And I agree with the comments saying that the blog isn't the best format to convey information since it's sorted by time. I'm in the process of redesigning my blog to sort by subject matter, and separate small code snippets from more in-depth posts.

On another note, I wish more programmers wrote about topics other than just technical ones.
This is a motivational poster, but it doesn't reflect reality. There are lots of people who go with the current and also against the current. The majority of people who go against the current of mainstream knowledge are quacks or misguided or simply not competent to make the discovery they want to make.

The few who make novel contributions are not representative.

People working in groups building on the success and knowledge of others make the vast majority of meaningful contributions in all fields.

Actually, a useful application of NLP would be to detect this kind of ambiguity before it's published (or written into contracts or laws).
If you start with mass per distance (kg/km), and you divide by fuel density (mass per volume, kg/L or g/mL), you get area (ca or m^2).

If you start with distance per volume (km/L) and cancel the matching units, you get inverse area (ca^-1 or m^-2).

This doesn't make sense until you realize it is the conversion factor between volumetric flow rate and volumetric flux, and is the number you need to associate volumetric fuel consumption rate (volume per time) with speed (distance per time), which is exactly what you're doing when you think of the fuel supply as a continuous trough.

This is a simplification. Different vehicle speeds will be more or less efficient. Volumetric flow rate is an integral of the volumetric flux over an area. So the area is the average aperture size. If your vehicle had a mass-ignoring, initially-empty reserve tank of infinite size, scooping up fuel from an infinitely long trough with the specified cross sectional area, it could go an infinite distance. You need the tank because different speeds may require more or less fuel flux. You need to travel at a more efficient speed before you can go to a less efficient speed.
I'm British and prefer mpg. Why? Because for starters kilometres are alien to me, but also because it's just familiar and relatable. But with that said, the numbers manufacturers give are never even vaguely useful IMHO (my car is technically 40mpg but I get low 20s) so it's more for comparison of efficiency between journeys than anything else.
Have you ever been to Long Beach CA? Take a look at the (frequently) dozens of containter and tanker ships idling just offshore. Any major port city will have the same issue, transport ships waiting, for various reasons, just outside of a port with their engines running. Any refrigerated cargo needs to be cools, which requires power, which means that they run 24x7 while sitting around.

there was a push to improve shore-power options for these ships a while back, but i'm not sure where it went. probably deemed to costly or intrusive by the shippers.
That's a sad reflection on out throwaway economy. Obviously repairs are often a much cheaper option. Further cars limited lifespan so 1 new car could mean replacing 15 cars 1 year sooner.
It is also a PR thing: they don't want the government to admit that the cars are pollutants.
"Being safe" does not matter as much as "having power" does.
I'm also wondering the answer to this question. To my understanding, go-crypto is actually maintained separately from the Go stdlib by the Go developers[0]. So why isn't this just a fork of crypto? Why fork the entire language? Why can't this be upstreamed?

On top of what everyone else has said:

If you are looking at smaller companies, there is definitely a tiered system in terms of the complexity and challenges that a company can offer it's development staff. One company's "junior" developer might have the experience to be a "senior" developer at a firm with much simpler problems.

Some people have the stamina that they can just keep solving the same problems over and over again without getting burnt out. I think most people though, will have a tendency to seek out novel or more challenging problems as they grow. Someone working on problems they find too easy will lead quickier to burn out, likewise someone working perpetually on problems that are way above their head can lead to the same.

I have changed firms three times in my career, and each time I sought out a company that was doing something more difficult than the last. With each company, I've come in on the lower-end of the team's skill curve and worked my way up to the upper-end of the skill curve. Then, I got bored, burnt out and moved on to something more difficult.
Author here, I'm sorry if the article felt that way, that wasn't my intention at all. It's true that it's something that works for me (and probably for other people) but people should obviously do what they want.

I still think everyone should give it a try. Maybe it won't work for them but it could be great for others. They won't know until they've tried ;)
It was the felony and the limits on his future in politics that drove a lot of it.

Some jail time wouldn't have been enough. I think he would have done that. Maybe while in there, bad things might have happened.

But, it was obvious to me Schwartz understood code, people, how to organize and advocacy. He wanted to build a body of people and power and do some things.

To him, a felony conviction undermines all of that, and he saw it as useless, himself useless.
Are you sure? I'm not. Who controls what the BND is doing? Oh, yes, I know, they report to a group of politicians, right. They already admitted, that they are overworked and have not the facilities to check up the BND. Also, the BND already lied to parliament ... I guess, the BND is likely worse controlled than the NSA and the NSA has still more control over the BND than our own parliament, since the NSA is in the same building as the BND surveillance team, the politicians from parliament are not (they are hundreds of miles away in Berlin).
> Sure, if you ask a person, they'll weave a heartfelt story, etc. but the truth is in what they do, not in what they say ... and the majority of us do nothing or worse.

I'd say conclusion is the opposite - there's little "free will", people generally are slaves to the incentive structures they live in. People follow incentives so predictably that at scale there's little sense in talking about individuals - it's exactly corporations, governments and markets. Behaviour of system as a whole dominates over behaviour of individual components.

They don't even need to be bought or intimidated. Both sides see terrorism and other conflict with glee. Republicans can exploit fear of others and hatred to perpetuate themselves in office. Democrats can exploit fear and hatred of Republicans and the government to perpetuate themselves in office.
There is a doctrine called "constitutional avoidance" - if a court can decide a case on grounds without reaching a constitutional question (particularly a close question), it ought to decide the case on the alternative grounds and avoid the constitutional question.

So, for example, a court might say: This action was improper because it was not authorized by Congress. That is all we need to decide. Because we made this decision, we don't need to reach the constitutional question. Of course, if Congress had authorized this action (or now does so), and this case is back before us, we will no longer be able to take that path. We may, at that time, decide that the congressionally-authorized action is unconstitutional. But because there is no need to do reach that decision at this time, we decline to do so.

Considering the federal sentencing guidelines for the specific crimes he was charged with and the parameters of those offenses (non-remunerative, no prior convictions, limited damages) his own lawyer wrote that he believed that even had he been convicted, he would have landed in the sentencing levels where probation would have been allowed.

Surely he knew prison would be a likely outcome of his actions? If he was not prepared to do jail time (like hundreds of other hackers and activists had done without a whimper), then perhaps he should have recalculated what he was doing.

For someone so intelligent, it seems he didn't fully understand the implications of his own actions, which is puzzling on several different levels.

While his suicide was a tragedy, it was completely avoidable.

What moved me the most was Lessig. Aaron got right into Larry's soul, and once there, asked a simple, genuine question that could not be denied. There is a quiet power in that I find profound, as if we all operate under limits that really aren't there when we really do question.

"Sweet, sweet boy." Yeah Larry, indeed.
Or, to use a real-world example, does it matter who is President of the United States? The federal government employs 4 million people, and the President has far less control over them than a CEO has over their employees.
Larger ships do not pollute more. Per unit of cargo they pollute less.
> The validity of eyewitness testimony is vastly overstated and having it all be treated as if those giving it were lying would be an improvement because they are often not telling the truth because their memories are imperfect, though they do believe themselves to be telling the truth.

Fine. How would you deal with the forensics people deliberately presenting DNA evidence that never existed? How about the police officer who testifies that they found the fingerprints of the accused at the scene of the crime? How about the totally forged chain of custody for evidence? What about the bit where the police stitched the interrogation tape together so that the accused has a recorded confession?

Suddenly you turn a mostly reliable court procedure into one where literally nothing said by anyone can be trusted. Sure, eyewitness testimony can be unreliable, but there's no need to turn it into a kangaroo court.

I don't think you can make the second claim without some kind of evidence at all.
>"Crucially, this capacity is narrow and specific. Today’s AI produces the semblance of intelligence through brute number-crunching force, without any great interest in approximating how minds equip humans with autonomy, interests and desires."

I'm not sure why we would want AI to have autonomy, interest, and desire? It's almost like solving a problem that doesn't exist.
So how many then? 5? 10? 20?

I think it is kind of important to point out that there isn't much that was shown in the video, that is different from a traditional low-temperature lab (although I am not an expert). The only differences appear to be the compact casing (with some shielding) of the D-wave box and the D-Wave chip itself (whos "quantumness" is a hot topic). The rest of what was shown in the video was a traditional dilution refrigerator setup. I say this not to make a point about how bad D-wave is (they do some good stuff), but to try and separate what is traditional equipment, versus what they claim to be innovating on. I feel this is necessary as dilution refrigerators can be pretty damn impressive and could cause people to think that was the main part of their invention.

I don't think that OpenSSL is a great example of OSS, there are several areas where they don't follow bad practices for no reason and you can just look at their history of serious security flaws. Why would you want to integrate with that? In this case it is better and cleaner to implement the functionality in your code (in this case Go).
Alcohol poisoning isn't the only kind of poisoning. If it weren't for widespread ethanol consumption and acute cascading organ failure, it wouldn't really even be important.
What you lose when you move away from text logs is not any real benefit; what you lose is the illusion of control you have with text logs.

Text logs can be corrupted, text logs can be made unusable, you need a ton of domain-specific knowledge to even begin to make sense of text logs, etc.

But there's always a sense that, if you had the time, you could still personally extract meaning from them. With binary logs, you couldn't personally sit there and read them out line by line.

The issue is psychology, not pragmatism, and that's why text logs have been so sticky for so long.

>If the goal is to keep humans safe and happy, it might imprison everyone in playgrounds, and drug or lobotomise any unhappy people, or restraint any suicidal people. Or, if you specified "happiness" with pictures of smiling people, it might resort to facial reconstruction, or it might just tile the solar system with molecular smileys, because that maximises the "make people smile" goal much better than actually making people happy. And while we're at it, happiness isn't the only thing we care about…

FAA Backs Major Drone Research Efforts, Mobile Flight Planning App
Don't think of "wanting" as a soul-like action of a little person in the machine. "Wanting" is a shorthand for anything that is the result of a goal system and autonomy. In the simplest sense, giving a drone a map of its surroundings and giving it a location as the goal for its path-finding optimization algorithms, the drone now "wants" to go to that location.

Key thoughts.

It is always important to remember that the Section 215 progam is not a significant authority under which the government conducts surveillance on US citizens. The metadata program is a little used program and the data is not co-mingled with the larger XKeyScore dataset. As a result, the IC does not fight as hard to protection Section 215 authority as it does more significant surveillance authorities.

Because the Section 215 authority is expiring, the IC has every opportunity via the Freedom Act to create stronger statutory authorities under the guise of reform. Straight expiration of the abuse 215 authority is the strongest reform message.

You're allowed to feel anger and disappointment over suicide. But for the most part, victims of suicide are succumbing to a disease; they aren't failing to live up to a standard.
If the AI doesn't have its own intention (perhaps having intention is a prerequisite for being truly intelligent), it's conceivable that we would program it with an intention or goal, such "find the most efficient way to produce as many paperclips as possible". If you assigned such a task to a human, it's fairly obvious that the task is subject to other things which are important to humans (for example, don't enslave or kill people to build paperclips, don't replace strip-mine all our farmland to find more paperclip material, etc.). But since an AI doesn't necessarily share, understand, or agree with all the implicit values we have, it's myopic view of the world could cause it to destroy us as a mere side-effect of trying to achieve it's singular goal.
