HFT, when it is done at milliseconds of latency between exchanges to trick an order into executing at a 'fair price' because the order was sent to one exchange and HFT 'arbitragers', decide to manipulate the price at other exchanges due to latency for the same stock buy/sell.

It is arbitrage free, riskkless arbitrage that adds no value to a market, as it creates none but destroys it. Arbitrage adds value to a market by offering something cheaper; HFT removes the cheaper for the more expensive.
A bit of a tangent to the article, and your point at large, but i must: For the politically minded: the Tea Party promoters are not libertarians. The basic platform argues for an increase in government control over social issues. The antithesis of the libertarian definition.

The Tea Party is really just farther-right conservative.

>The quickest and most painful solution to the crisis would involve greatly reducing the amount of money that students can borrow to attend college.

Ya that won't happen. The fed wants their share of the pie as well, and since you can't get out of your student loan, even through bankruptcy, the government will eventually get their money back plus interest. There's no incentive for the government to reduce it. If anything they'll increase the funding so they'll get more interest out of future generations. Also college being the de facto next step after high school it'll be like this for at least decades to come.

You'll have to be like the Japanese tsunami stone markers: "beware of tsunami and don't build below this point", and tell your kids "beware of easy money and make sure it's worthwhile" but it's gonna be pretty hard to go against the government system.
The exam paper is interesting to look at, but whether it is actually a difficult exam to pass depends far more on the stringency of the marking scheme and how much the average entrant actually knows. If half the people taking the exam don't know who Weber was and you can pick up 3-4 marks on the question for making generic comments about the internet and rationality, that question suddenly looks a lot less challenging, especially when it's only 2-5% of the paper.

I'm not well qualified to comment on the Indian-themed questions, but most of the world affairs questions don't appear especially difficult to write a vague statement that picks up some marks even with general ignorance of the subject matter, and I'd suspect that most people with a decent interest in world politics and current affairs (and a good education) could get middling scores on those questions.

If anything, I'd be more concerned about losing marks from not sharing the same view as the examiner on "Africa was chopped into States artificially created by European expansion." Analyse and "Male membership needs to be encouraged in order to make women's organization free from gender bias" Comment. (especially if being marked by a bureaucrat rather than an academic) rather than the inherent difficulty of the subject matter.

What matters much more for the actual difficulty is whether it's intended on selecting the top .5% or just screening out the bottom 50%. And perhaps also whether some of the more controversial political questions are marked based primarily on knowledge, nuance, or adherence to the viewpoint of the examiner.

RxJava sounds like a nice formalization of how I have been "doing it" with Guava's ListenableFuture and single threaded executors. I always declare up front how tasks are distributed across threads and don't rely on random scheduling from a queue. This also creates opportunities to avoid locking and migrating data between threads.

It's about as painless as it gets when you aren't bottlenecked on number of actor like things. I never am because I eat the pain of not blocking rather than asking a framework to do it for me (or fail at it).

Java 8 has CompletableFuture so you don't need to leave the JDK anymore, but the javadoc makes my eyes bleed compared to Guava's ListenableFuture. I do like that CompletableFuture doesn't use synchronized internally.

The thing you have to aware of with async is backpressure. You have now decoupled thread pool exhaustion from task creation allowing unbounded memory usage. And once you allow backpressure you need to start thinking a little bit harder about deadlocks due to bounded queues.

Eliminating cycles, ignoring bounds where cycles exist, or allowing errors/shedding can help, but it's the kind of thing that keeps me up a night.
I've wanted the ability to combine things – e.g. setting headers on a non-200 response. It'd be nice if there was a way to combine supported options into a single request or at least as many as will fit in to the querystring.
The example he used in that article was an adjunct making $15k and a professor making $60k.

If that $60k is actually his salary, that's not great. Now, if one of the other commenters is right and he's at UT Arlington, $60k is a perfectly liveable income here, but any professional job with more than a few years experience is going to surpass that. As a software engineer in the same metropolitan area with about 6 years experience, I make $66k/year. I'm not even that good, and I'm probably younger than him.

I personally am very interested in IPv6, but the regular expression notation is more complex than IPv4: IPv4 has four decimals separated by dots; IPv6 has as many as 8 double-byte hex characters, sometimes as few as one (e.g. ::1). Plus, other than myself, I know few people who regularly use IPv6. It's not an intractable problem; I just wasn't ready to put the effort into it.
> decide to manipulate the price at other exchanges due to latency for the same stock buy/sell

Be clear what you are saying. They are "manipulating the price at other exchanges" by changing the prices they themselves set on their own inventory.

It is not arbitrage, it is price discovery and it is not without risk.
Braintree vs. Stripe vs. Paymill vs. Amazon Payments
Hi all,

What payment system(s) do you use and why? The info we have gathered so far indicates that Stripe and Braintree are the best options (eg, price, support, ecosystem etc.).

You should also go right to baggage claim when you land. Most airports don't have someone looking at the bag claim receipts, so thieves can walk right out with a bag.

That was an interesting read, lots of good points. But I think that articles points are orthogonal to mine. I agree the US is a much less healthy place than many other industrialized countries. But that isn't a reflection on our health care industry, that's a cultural issue. If the US has a higher rate of breast cancer remission, but an even higher rate of breast cancer occurrence, that would reflect well on the health care system while resulting in a increased years of life lost.

You're doctor can't make you stop being fat, he can't make you jog, and he can't make you stop stressing about not jogging and being fat :P But in the US he can give you an edge over other countries in beating cancer.

It's an extremely tough problem to determine what is cultural causes, what is genetic, and what is health care. But just normalizing on age incidences, the US does well. I bet if we adjusted for relative health (impossible, but I'm wishing for perfect data), the US would do remarkably better.

If I have time later today, I'll dig up my sources. But I lost interest in this years ago when people overwhelmingly thought that because the US has a higher mortality rate, our health care system must suck :/

Best of luck to the guy as he figures out life in not roses and that taking a stand can be very stupid and not nobel, something I think he thinks he is doing here.

This is silly. The 'tablet market' is not in need of saving, it's just reaching market saturation - these things are markedly tougher and longer-serving than laptops, and most people that want a tablet now have one.

Netflix and Chrome continue to run just fine on my 5-year-old iPad, and that's all I use it for - I'd consider that remark extremely market-typical.
Okay lets say you actually make a website's who entire job is to answer simple tech support questions via a user friendly question/answer interface that is self indexed by itself.

Not just indexed by google. Then you'd actually be providing a service. Otherwise your just a single reference, no valuable or critical then any other. I can just grab the next result.

What you described is inherently worthless in this day and age. That one fact may exist on hundreds of different websites, yours generates no value to myself, its existence is irrelevant due to its ease of replacement. Why should I support you?

> There is no one-system-fits-all and it can't even be said that one system is necessarily a better choice in any given situation. Status-quo is usually a good choice though, if it is working

I mostly agree with this except currently the Status-qou isn't working for most people and the environment. The pendulum swung too far towards the "government bad, markets good" end of the spectrum. To tackle the big problems of the day (Climate change, income inequality, chronic unemployment/underemployment due to technology changes and automation, etc) we will need much more government regulation. That includes local and national regulation with unprecedented global cooperation. The free market on its own has proven itself incapable of solving the problems society faces and in fact is causing some of the above problems.
Be sure to read up on the specifics and downsides before doing this... there are still plenty of horror stories (though instead of equipment theft/damage the stories are more about bureaucratic snafus).
It really isn't. Copyright is riddled with exceptions of many kinds, and the granting of it is completely in the hands of whatever a government wants to provide.

I think it defeats the purpose of a TSA lock. Is it still allowed in the USA?
Your bag gets hand-inspected by a TSA agent with you present. They'll ensure the weapon is packed securely and that the ammo is in original factory boxes (meets ORM-D requirements). So you can't declare a weapon without actually having one.

Note that "packed securely" can have different meanings at different airports. There isn't a uniform standard or branding on cases that meet airline and TSA requirements for weapon transport. But you'll have the fewest problems with a Pelican that is fully locked.

Not entirely. For example many forms of music are subject to either compulsory or statutory licensing. Also, the United States government has long held that it does not need to comply with patent law for its own internal use (e.g DoD can ignore your patents).

If you write/compose a song, and/or record a song for the public in the United States you do not have complete control over it anymore.
No. They will make you open the case and show the gun is safe/unloaded. They then affix a tag to the gun, which declares that there is, in fact, a gun in this case (with the tag inside the case, a rather surreal requirement).

I think maybe it's a way for the institutions to avoid responsibility for the result.
That's certainly true. But even if there was a way to detect post-TSA tampering, what useful recourse would one have?

It seems that in either case, checked luggage is at risk of being tampered with, searched, or outright stolen and there is very little we can do about it (aside from filing a claim with the airline and hoping for the best).

> I'd imagine you need to check-in in a different area and not the front desk?

Yes, and at some airports you get your very own line (which is almost never busy). I've saved multiple hours at certain major airports because of the separate screening procedures/lines.

Most of the time, though, you'll just go to a normal desk, say "I need a firearms declaration," and they'll check you in as-normal, until your bag needs to be screened. At that point, you'll go to another area, unlock the bag for the TSA (if it alarms) and receive a hand-screening.

Paywalls don't make as much sense on the web because of hyperlinking. I don't read articles from just one source (like a newspaper) I'm reading tiny bits from hundreds of different sources in a day.

I'm not sure the best way to monetize that but a paywall on a single domain sort of misses how 99% of the audience actually uses the site.
Or at least "as an american" added to the title.
That's pretty negative. Some parts of society are constrained by physics e.g. energy, food, transportation.

Engineering has a thing called 'control volumes', where you draw circles (volumes actually) around a system, and measure inputs and outputs. They must balance for a steady state to be achieved. Maybe by measuring things that actually matter (instead of for instance completely imaginary point systems like money or votes) we could constrain society to at least be stable.

While I agree that you are correct under current laws the position as I see it is about it should be fully legal to copy any publicly published piece of information.

I am not too worried that literature and art will go away. Literature and art existed before we had avenues for mass audience to buy or rent personal copies and they will continue to exist after we dismantle copyright.

I'd like to note that I support trademarks. I do not condone people selling modified versions of Microsoft Windows including keyloggers that call home to the seller and claiminf it is official, unmodified Windows. One shouldn't sell malware with someone else's trademark on it. The problem as fsf explains well is that we have grouped disparate things together under vague intellectual property when the entire exercise is anything but intellectual.

So it's a small in-process library for writing and reading append-only logs on disk, that supports multiple threads concurrently reading and writing as a pub/sub system.

It seems inspired by the Apache Kafka project in that it organizes logs into named topics, but it is not networked, does not split topics into partitions and segments, and does not do housekeeping like deletion of old logs.

It looks pretty new and immature, for instance https://github.com/panyam/KafkaLite/blob/master/src/kltopics... reads from a potentially uninitialized field and could randomly fail (but will not propagate the error!). Have the tests been run with Valgrind?

Not bad, but it could definitely do with an introduction in the Readme describing its purpose.
