I'm not sure I understand what you are saying. How does the brokerage make money off of that. If they are improving the price you haven't lowered their risk profile at all.

If they are taking the other side of your trade and the market doesn't reflect that, they've actually given you a free roll.
This is the correct answer. You're running a business - enforce business hours on your business contact number.
Okay, that's cool. Radically undiscoverable, but cool.

I have done meditation for years now and found it to be very beneficial.

However, I find this article to be very Cargo Cult and am disturbed that nowhere in this entire thread has it been called out as such.

"Look! Meditation must do things because we can make these colored charts telling you about beta waves. What are beta waves? Well, it doesn't really matter, just think of them as bad, because look, meditation does things to your brain, okay??"

The benefits of meditation to mood, creativity, etc are pretty easy to verify for yourself, subjectively. It disturbs me that we feel that adding scientismic mumbo-jumbo gives it credibility somehow. What is presented in this article is not actual science.

There is actual science involving meditation and the brain, but it is in extremely early stages and is hard to draw conclusions from. Our understanding of the brain, in general, is very early! Please be suspicious of pretty colored charts showing brain activity.
maybe they can integrate in someway with the upcoming Google Helpouts.. (using an API that will be later on shut down by Google, of course.. :))

Oh, painful point, I still try to ignore Scala's compile time and hope it will improve in the future, (it does gradually on every release) but when I do, then Scala feels a bit more natural to me than Go (it feels closer to Ruby for me, which I like, and has the Java interop aspect, which I unfortunately need). I just close my eyes, do sbt ~test-quick, and hope for the best. It's just that Scala feels to me more like a statically typed Ruby, where in Go I need to shift some paradigms and do some mental twists to accept how great it is.
I wish someone had told me that back when I worked in the public sector, all my colleagues too! We thought we were all trying to execute public services well. Is the work avoidance conscious or unconscious? If it was unconscious have I lost it now that I work for myself or am I secretly undermining my own business? Please, tell me all about myself.
I don't think that you're making a "computer in the home" argument. It's more like tools.

In 1960, a typical handy homeowner had a hand tools. Sure, I could build a deck in the backyard, but it would take a long time and require more hands. Today, a typical handy homeowner has power drills, saws, etc at very low price points.

I think the post describes a way in which this particular abstraction is "leaky." We have to hope that the abstractions we rely on every day are less leaky and thus allow us to get by without intimate knowledge of the underlying complexity.

I create a spreadsheet with ideas down the side and then categorise the columns with different criteria, things like :-

* What price will it be sold for

* How much will it cost me to start up

* Can I do it all myself / is outsourcing needed

* Is it an easy sell / impulse purchase

* How many people have said they would be interested

* How long will it take to get set up

* Does this sound like fun to work on

I would highlight quite positive answers in green, so I can see at a glance with is quite an attractive idea to work on.

I think it's important to then take your own passion & preference in to account. For me I might prefer to pick something with a higher potential revenue with a bigger list of interested people, where as you may put more weight behind something that is short to work on & fun.
"Two years in, Go has never been our bottleneck, it has always been the database."

I would expect this to be true with any language, if you code well. Regular web applications do not have state so they are very easily scaled horizontally anyway. Databases on the other hand are trickier to scale the same way and will end up being the bottleneck almost all the time.
Your application is not fair at all. It looks like your sleep mimics I/O boundedness, but in reality it does nothing but set an arbitrary request length. In a real world application I/O requests contend for resources with eachother. Sleep calls don't contend with each other at all.

This means that application servers can just keep stacking concurrent requests with perfect performance. If there was actually I/O being done that took 250ms, then you would find that it was the real bottleneck, and it would be the dominant factor in your benchmark, with the differences between app servers all but disappearing.
This touches on a semantic point which confuses many new programming students: in algebra, the "=" is a specification of truth; in programming, the "=" is an operation of assignment. There is a difference, as in "2 * x = x + x", which is perfectly sensible in the former but pointless/absurd in the latter context. Also, "x = 2" in algebra is the notion of "when it is true that x is the same as 2, other truths occur", a different notion than "store value 2 in variable x, then see what the consequences of other operations are." Alas, the nuance is hard to grok until much later in learning both.

I suspect that the government is more interested in the activities of left-leaning groups like Occupy. This is another data point supporting that hypothesis, albeit not a strong one: there are far fewer Facebook users in Pakistan, for one.
Could such a system, on a more grand scale, replace railroads as conveyors of passengers and freight? The vision is not new-fangled, and a modern day visionary insists it could be a better alternative to high speed passenger rail.

The interesting thing is that the incumbent railroads are actually in a prime position to capitalize on this tech. The hard part about implementing the system isn't really the technology, it's all of the property, right-of-way, and NIMBY issues that come up. However the railroads already own property all over the country and (for the most part) they can do what they want with it.

Everyone might be better off working together than trying to approach it separately.

It's offensive in Sweden.
There are ad-blockers for Android, they don't even require root on 4.x.

There are also WiFi routers that filter all traffic.
I was a bit dubious at first, but I understand what they're on about now:

The concern is that goods will be finished much closer to PoS, resulting in more transport of bulk commodities and less of finished goods. Intermodal transport (which includes those loooooooong double-stack trains you often see) is primarily finished goods going to market. If railroads want to stay competitive, I do agree that they need to "skate to where the puck is going" and make sure they have the capacity to handle shifts in traffic patterns.

A good example is the Powder River Basin. That is the largest coal producing region in the US and for about 30 years has received massive capital investment. However, coal is on the decline and crude-by-rail is on a massive upswing. The railroads got caught flat-footed there and have been scrambling to increase capacity for crude-by-rail.

As far as bulk crude, how else are you going to transport it outside of a pipeline? In this the railroads are safe, but in the future they may not be.
I think that for them the situation improved.

If they called me to see if I knew their password and I didn't help them they'd feel stuck, now they just go in their inbox, find it themselves, and go on with their lives without emailing me, which ultimately doesn't piss them off.

Before, I just couldn't handle the amount of calls and sometimes I just wouldn't even call back if I thought it wasn't important, then people would have to call me back to finally try to solve their problem. Now, I always reply to my email, so in this case, too it's better for them.
I doubt Hyperloop is the future for freight, and freight is overwhelmingly where it's at for railroads (in terms of $$$). Hyperloop is built for passengers, where speed is the overriding concern. For freight rail, price of transportation is the primary concern. Accelerating a few tons of iron ore to nearly the speed of sound to get it somewhere is prrrobably not worth it.

I don't even think I really buy the "3D printing will change everything" take either. Railroads will still be perfectly useful for shipping 3D-printer feedstock to distribution points for feeding the 3D-printing micro-factories.

Unless the author says that passenger rail - in the US, that'd be Amtrak - should watch out for the future, in which case I'd say that's been patently obvious for longer than I've been alive . . .
Another Scala user here. And I've been using Scala for the last six months. Mostly developing web applications on Scalatra and Play. I love Scala - It still has its goodiness and it's an excellent alternative to Java.

If you notice in all of the Scala books (I've read the one by Martin and the One by David Pollak as well), they all seem to push you towards the functional programming model instead of the much more common imperative model.

But you know, there's a problem with that. Not with the language itself, but with the web development side of Scala. There's only certain ways by which you can program with a particular function that accepts a request and returns a response. So, most of the time, I would find myself wasting time thinking "How can I make this more functional?"

Functional programming is really great when you can actually enforce it - When writing algorithms and so forth, but otherwise, you are forced to fallback to this imperative model which sucks, because you have to constantly keep changing your mindset between these two models.

Another downside of Scala is its HUGE syntax. Processing strings? Here's a ten million ways to do it.. (a bit over-exaggerating). Oh and if you chose this way, then you should use this syntax. No, not that one, THIS one. Oh no, not that one, this variation of that one that looks like this.

I've advocated Scala to many HN members here in the past, you can even check out my comments, for instance. But from my experience, I think Scala is an Academic language. But it's superior in its own ways - I just LOVE the concept of avoiding nulls and passing an Option. It's beautiful. But the downside is its huge academic complex syntax. I want to be able to write code which shouldn't reduce my hair count even if I look at it after 6 long months. I don't want to refer to an 800 page book each time I'm confused about something.

That's why I think Go is beautiful. The syntax is just enough to keep it inside your head forever. I fear that as the language matures, this might also evolve into something as complex as Scala, but let's hope not so.

Go isn't a magic bullet though. It has its own downsides, but nothing w.r.t performance or similar. For the most part, it's awesome.

Once you go Go, you never go back.

P.s - I still love Scala as well ;)
He has, actually. Declared all of it a big mistake. He's also declared it a CIA conspiracy several times.

Watch the movie "A beautiful mind".

Unfortunately, the theory was analysed by mathematicians and, under certain assumptions, was proven correct. In a system with many independent actors pursuing their own interest, anything that isn't a Nash-equilibrium cannot exist for a long time. Anything that isn't Pareto-efficient will be very, very bad for 99% of those independent actors.
Each package does not need to be in its own repo. You can put packages inside subdirectories. The standard library is full of these, such as the net library. There is the net library itself, and there are subdirectories, including http, smtp, and more.
Great explanation of why this is exciting. Separation of js/css/html is great for the top down structure of a project, but a major pain from the bottom up. I can see myself making heavy use of web components to fix that.

Also it will be interesting to see how this shakes up the templating/data binding framework ecosystem.
Yep - if you pass a path the behaviour is as normal, but it's still overloaded to support the path inference behaviour. I guess it's not really monkeypatching though as `Module` itself is not modified, and you have to deliberately choose to use `ActiveSupport::Autoload`, so I reluctantly retract my parenthetical snark. :-)
>think of what the racial makeup of prison would look like 5 years after you started giving smarter people lesser sentences due to their lower rates of recidivism (and vice-versa)

The above statement implies that if you let smart people out prison, the racial makeup of prisons would change. This indicates a position of assigning a pretty high correlation to intelligence and race; ie, a prejudice based on ethnicity. Seems pretty clearly racist to me.
My intro course used Modula/2. (Many years ago) We were less focused on the computer interaction (memory) than algorithmic complexity (Big O notation). This doesn't mean one method is better or worse, just what we used. The advanced algorithm coursework was all about proofs, and and had no programming.
The RoW is highly valuable for all sorts of stuff. Back in the day, iirc, Qwest was owned by Phil Anshutz, who also owned the Southern Pacific Railroad. He used the SP RoW to lay down huge tracts of Fiber, which the other railroads copied.

They can and do run all sorts of stuff long the tracks - fiber, natural gas pipelines, and soon high transmission power lines.

Update:

Sorry if someone did feel offended (the negative voting), I said it with my best and more constructive intention.

In my opinion, the problem is not in the content of my comment. Well, maybe, if someone understands it as: "oh, can't argue against that, is attacking the language" instead of, "let run your imagination to 2023".

Suppose you want to buy XYZ for $1.00. You place your bid and are the highest price against a $1.03 offer.

Evil broker places a $1.01 bid and gets a fill.

He immediately offers $1.02.

Case 1: The market runs up, he makes his tick on essentially zero commissions. On some markets, you earn commissions for providing liquidity.

Case 2: The market falls off, he smacks your bid and only loses a penny.

This is edge.

EDIT: When I say "the market", he could base his actions off an index. As for "free roll", sure... but there is still an impact on liquidity and you're in a situation where you are more likely to get a fill whenever the market is going against you.

Life without a hammer...

I used to have a hammer and beat myself on the head with it. Now I don't have a hammer and everything is better.

Amazing.
Oh, get off your high horse. coldpie said "I do not respect the job these people do" and "I like to degrade their position of authority", not "I do not respect these people" and "I like to degrade these people". The TSA performs no useful function and is actively harmful through regular abuses of their position of power. Their employees are still humans and deserve to be treated like them, but their job deserves no respect, or else the term "respect" is now meaningless. Their position of authority absolutely deserves to be degraded. Take your straw men elsewhere.

Also, "non-existant" [sic] is exactly where I'd like to see the TSA.
Yeah, it's quite convenient. When I'm short on cache I just DDOS my biggest competitors.

Well, we may find a hyperloop is better for transporting the smaller pieces of a commodity. After all, if you can just send a crate instead of a container, you can send to the buyer exactly what they need and nothing more. The issue with bulk freight is once you've made the pellets, at some point they have to be divided up.

I think something like a hyperloop will do very well for less-than-carload/container freight, but would probably never transport the massive volumes of bulk products (chemicals, wood, oil, coal, ore, steel coils, etc.)
Yep, actually at the beginning I thought I'd do that. They call it "virtual office" here, there are reps pretending to be your secretary, who pick up and then send you an email with the transcript.

Then, email worked so surprisingly well that I just dropped the idea.

That benchmark is fair if you consider the context: I/O bound workoads. On those kinds of workoads, your app spends a large amount of time waiting for I/O. While waiting, it does not use any CPU. This is very well simulated using sleep calls.

> I think Scala is an Academic language

Sometimes "academic" seems like a catch-all for stuff people don't like. Scheme has a strong academic history in its use and implementation, yet it seems to be described as "academic" only when someone is unhappy with how minimalistic it is, which is the opposite issue described here.
I wish this had a private version for conversation within an organisation
Very interesting read. It's not only a problem with mathematics though, it's nearly every subject in school, whether it's science, languages or math. It seems to me that the problem is that to teach well, you need good, autonomous teachers, and that just doesn't scale. Like the author said, you can't teach teaching.

I'm of the unpopular opinion that digital learning is the only possible solution for this. I'm talking about a digital tutor with infinite patience, with the best qualities of the best teachers. I'm not talking about a robot that passes the Turing test, just one that passes the test for the narrow field of teaching a specific subject.

People say you need real teachers, you need the human touch, but if the average teacher sucks (and they do), then I'd rather be taught by software. And I think it's just one of those things people say because it sounds true: "you need the human touch", just like people said they prefer real books over e-books, face to face conversations over texting, navigating by feel over using the GPS etc. These sentiments almost always turn out to be wrong.

Hobby, Science Experiment or Suicide: Where Does Your Startup Idea Lie?
You need to spend some serious time with people that use your competitor's product day-in day-out.

Ask to sit with them, watch them work. Find companies that use it, ask why & when they chose it. What kind of agreement they're on.

Often moving away from a crappy product is really really difficult if you have to take your data with you. That's often the main reason crappy products stay in business is because people are scared attempting to even broach the subject of leaving because it's a major overhaul.

Don't compete on price - ever. Customers that move to you because of price will also move away when a competitor prices lower, and there will always be someone willing to cut margins low enough to put you both out of business.

Compete on quality, insight, deeper research into how the product is used.
