So some thought about this, as I used to be regular of a local casino, not because I felt I had to go, just to play with cash vouchers, they used to send, maybe occasionally putting in a 10 dollar bill or two. I didn't make money out of it, but I did not lose my own money. I guess when they realized they are not making money from me, they stopped sending me those vouchers... Bummer! :-)

Those machines are really designed to salami slice players. You can play many of those machines from a penny per line, which equates to about 15 to 30 cents per play for full lines, depending on a machine. There are people who play at higher stakes, like a max bet of $2 per play, or even $5, but observing people, majority seems to be played at much lower bet of a penny or two per line, so I'm guessing they consists of high fraction of profit a casino is making from.

It's fairly easy to lose a sense of spending when you are doing literally a thousand play per hour. (At 30 cents per play, You'd be spending fairly long time to spend $20, or even $10. At this level, a typical win would get you around $2 to $5, maybe $40 if you are quite lucky -- and perhaps real jackpot, being very, very rare, $200 or so.) Those "wins" really give you the joy that you'd anticipate for the next, and a lot of time, they'd put more money in just to anticipate another win, because when they have lost plenty of money, it's about a time they will start winning, right?

Knowing someone who really got into it, one sign I started seeing from them is that they'd start making a statement like "I'm not playing it for money, I play it because the game is fun." He would play the game literally for hours per session, often visiting there multiple times a week. Usually ends up losing -- maybe the only good thing is that he'd have accumulated quite a bit of free restaurant credits.

So if you are inclined to play, here's some suggestions, though for those people who would feel these suggestions are useful probably find the best is not to play at all:

1) Set a budget -- don't bring extra money. (And don't bring ATM card/credit card if you feel like you can't resist getting extra money out of them...)

2) Record every win/lose -- I've had Google Doc that keeps track of every wins/lose every machine. Every time I cash in, I'd record, every time I cash out, I also record that, that would give me balance sheet how much I'm spending/making.

3) Bet generously -- Don't bet a penny per line, go higher. You won't go anywhere with such low bet anyways. You'll have a better chance getting a better outcome going through that $20 in 2 minutes than spending 2 hours on it. Yeah, it may only last 2 minutes, but then you have good reason (See #1) to leave at that point -- and you are giving less chance for a machine to alter your psychology.
That's not my experience, validating the data has always worked by just spitting it back out to them without any alterations to the data.

3x to 4x material costs? Is that retail? What about selling at just above cost and charge these rates for the software?

The simple answer is you're using a definition of "fair opportunity" that is different from what the people who disagree with you are using. Opportunities can simultaneously be 'fair' and 'unfair' depending on which definition you use.

Personally, I don't find the Harrison Bergeron definition of 'fair' to be particularly useful. It seems to be questioning things for the mere sake of questioning things. Yes, in the cosmic sense, everything is unfair, but what's your point? Society wasn't made to give everyone equal "cosmic fairness". This is how you create a society where the gifts of peoples' talents and circumstance go unused. By contrast, the people who are disagreeing with you are interested in maximizing the usefulness of these gifts. Improving peoples' circumstances is part of this, but only one part.
the thing is, it's as visible as it always was. i'm on Win 8.1, Firefox - it's plenty visible, it's just not the first place i look and shouldn't be.

All of this is interesting from an engineering perspective, but the reality is that casinos don't have to use engineering to get you to spend money. They rely on addiction for their income, and there's no evidence that better slot machine technology has swayed addiction rates one way or another (although TITO - ticket-in ticket-out - has made it easier to lose one's money faster). According to one study, 2.8% of the player base accounts for 50% of net casino win; the top 10.7% provides 80% of the win [1]. Without the very small percentage of their visitors that become addicts, every casino on the planet would cease to exist in short order.

You challenged my point not by saying that "pulling the rug from under people" was unethical, but that it would remove people's motivation.

When I directly answer why it wouldn't, you act as if I was supposed to be explaining addressing the ethics, and that my answer betrays me as callous and uncaring.

But you didn't make the argument that society should avoid "pulling the rug from under people" for its own sake, regardless of its affect on motivation to work. So I didn't address that point.

I did, however, explain precisely the ethics of my viewpoint in my original post, you just chose not to address this, and took the easy way out by focusing on a technical issue (the effect on people's motivation to work) and then pretending I had failed to address a moral issue that you raised.

how many innocent people are going to die as a result of these attacks? The US Government has a less than stellar history with accuracy and airstrikes. Sure, they might kill a few members of ISIS, but they'll also kill innocents in the process. I don't feel comfortable knowing that Obama who has a family himself is okay with authorising such attacks without fully realising the repercussions.

Will airstrikes even solve anything? They'll just further provoke ISIS and make them shift their focus, it will be the best recruitment campaign any terrorist group could ever ask for. And when they retaliate and hurt innocents in the process, the US Government will have more blood on their hands.

Looks like we are heading for another world war/Iraq situation sooner rather than later...

I too micromanage my data and pay for overages. Firefox updates, assuming you don't skip them, are actually quite reasonably sized, averaging about 10MB a month for me over the last few of years, both major version revs and minor security updates combined. I consider my online security worth those 10MB because I've never been able to manage my bandwidth to the kind of precision where 10MB one way or the other would have made a meaningful distance in my bill.

All great tips.

Once I had a big win (for me) in Vegas playing craps. I walked away with like $2000, and each of my friends did (to varying degrees) as well.

So, what did we do? We lost it all back over the rest of our vacation. However, that big win did something chemical in my brain. I remember it very well and think back fondly of it. But I don't even remember how I lost it all back. The win is still salient and the losses forgotten.

I don't regret it because I had a great time, but all of your tips apply. 1 & 2) It's easy to remember your wins and forget your losses, so budget and keep track. 3) Go in big, because the more you roll the dice, the more likely it is you'll revert to the mean.

I'd add one: 4) don't use the machines and learn one of the table games. The odds are better and it's a social interaction, rather than an expensive video game.
> such markets weight present utility experienced by market participants by past wealth accumulation, and thus are progressively distortive in terms of distribution of utility

Are you against the accumulation of capital or do you feel it should have an upper limit? IMO money is a way to measure value provided to society and money saved is debt that hasn't been called in, whether inherited or earned. If society has seen vast productivity gains in the interim then of course money earned by mowing someones lawn a 100 years ago would go a lot further today.

I don't see the accumulation or ownership of capital as fundamental structural inequity
> Tabs are important to almost all web users these days

Tabs would be a useless feature, if the window manager did a better job at what they should do. In a "tabbing" wm like the one BeOS has you are much better served by one-page-one-window application.

With a bit of cooperation from the window manager you can get rid of tabs. I did it few years ago and my browsing behavior and habits have changed for the better.

Speaking of this, I find it interesting that ARM went back to a fixed 32-bit instruction width for ARMv8 (from 16/32 in Thumb-2). Any idea why they chose to do this?
Why do you want to avoid letting others know that you looked at their profile? I actually made a few business relationships just because someone looked at my profile and I looked at theirs or vice-versa and one of us reached out to the other. There is no way to form a relationship even if there is potential for a mutually beneficial partnership if you keep yourself anonymous because other person wouldn't know who looked at them.

If like most of HN, you are interested in startups and entrepreneurship, I will suggest you do not anonymize your profile. As an example, just a couple of months ago, I viewed profile of a CMU faculty who previously sold a few startups in the same industry vertical as my personal project. He noticed that I checked his profile, reviewed my profile and personal project and reached out to me. We exchanged a few emails and talked on the phone once. Recently, he brought me a very warm lead that could potentially become a very profitable customer for my personal project. And, all this wouldn't have happened if I kept my profile private.

In this case, an open ISA would allow more stability over time. More over, once we have an open and widely adopted ISA, one can build an open microcontroller. After that, embedded developers will stop getting bad surprises when some specific microcontroller is being deprecated / out of stock and the whole board (and likely large parts of the firmware) has to be redesigned.

And you're right: an ISA don't matter. It could be ARM, AVR or OpenRISC / RISC-V, but it's very desirable to be stable and embeddable into a SoC without purchasing additional licenses.
Ask HN: Learning Systems [Computer Science]
Hi HN!

I've been meaning to apply to a university for a program that has a strong focus on systems (OS, Distributed Systems). For the same, I'm required to do a couple of decent sized (i.e. university level) projects in C.

I have 2 questions

1. Are there any online courses that you'd suggest that has a lectures, assignments and preferably projects? Courses can be either like MOOC or just a course page with all the info freely downloadable.

2. Also, what are some good ideas on system level projects one can try working on (someone with no experience in C / OS) that uses concepts like threads, concurrency etc.
Is it hard to scroll on your machine. On a mac it is incredibly easy to scroll on a webpage, that is why I think these designs might be more popular.
Most of the comments against it here are in this same line. If the concept of NoScript even vaguely makes sense to you, or you've even heard the words "window manager" together, you're probably not the target audience.

I'll admit that most of these things (especially no settings) would make it a no-go for me, but I can definitely think of some relatives that I would love to stick on it and then not have to worry about them again.
Strange that adding smaller wins to slots has only just arrived, as such more complex betting systems have been proven to make playing feel more rewarding for decades.

E.g. in Finland all supermarkets and roadside cafes have slot machines, and complex betting tactics described in the article have been there at least from the 1990s. They do differ a bit from Vegas slots, as the profits go to charity and the jackpots are ~50€, but still they are carefully designed to maximise the profits on the long run.
It's literally indistinguishable from random static: http://silverspaceship.com/static/shot_2.png My guess is it may be making some small gains by learning "pixels are 20% more likely to be black than white" or something like that.

Dictionary wouldn't work either, unless you think the NN is more likely than random to produce sequences of bits that are exactly the same.

There may be regularities in deep NNs. For example, many learned features are basically exactly the same but rotated or translated in a different way. This is because NN's aren't inherently invariant to rotations or translations, so they have to learn multiple features for every possible variation. Another possible regularity is that the weights tend to cluster on specific sections of the input image and ignore the rest.

But this entirely depends how the weights are projected into an image. The image provided looks like random static. The standard method is to just create a separate image for every feature, and for every pixel becomes the weights of the NN from that input pixel. Like this: http://fastml.com/images/deep-learning-made-easy/layer2visua...

Standard image compression software should be able to work with that. But this won't work in higher layers, because there are only 3 to 4 color channels in an image.

In fact, since the first layer in that example is just gabor filters, you could manually code a program to create gabor filter units for that layer, and get massive compression. Don't know if that's true for all NN's though.

I said above that my guess is it may be making some small gains by learning "pixels are 20% more likely to be black than white" or something like that. Which fits with the image he provided.

I think you could have shortened your question to "why have a Downloads folder?"

Downloads folders are where files go to sit unused. I personally send everything to my desktop so files won't sit out of sight forever, but I think in a browser which is meant to be simple that asking where they want the file is a good choice. Why defer user action to a time where they have to do a large amount of a boring task when you can ask them to do it right there when they're most likely to know what they want to do with it?
Absolutely.

And then the blame often gets shifted to things like the language or framework and rewrites start being bandied about instead of analysing algorithm usage because the problem often isn't apparent when looking at profiles etc. unless you're used to looking for exactly this class of problems.

And people start talking about "Big Data" and Hadoop and similar when their data are really middle of the tree and can easily fit on a single server..
What I'm impressed about isn't just the work he's done - which is very impressive - but his ability to explain it. That skill is a very important skill to have.

And they all are great reads. I'm sure being able to explain his code has contributed to his skill as a programmer as well.
