I had a prof that did this. Except he sold his book through the school printhouse for $25, when the competing alternatives where all $200+.

It was hand-bound by some poor soul in the printing office and was clearly churned out with a laser printer, but it got the job done and saved everyone a bundle.

If the prof made some money off of this, I'm fine with that.
Had a somewhat similar story. Took a class whose instructor had written the reference book in the field. We used his textbook, but instead of having us buy it, he gave out free photocopies of the preprint for the yet-to-be released newest edition.
In the bookstore of my local community college, I saw the required intro calculus text selling for around $140. That is wrong in so many ways.

And it's instructive to contrast textbook prices with the very reasonable student discounts on software. Software labels are trying to create customers for life, while book publishers are price gouging while they can.
This was a big mistake on my part, and I'd like to thank you for pointing out how stupid it was for me to do such a thing. I have now replaced that entire section. I am very sorry for anyone I may have offended by doing such a thing.

Congrats on launching. I am always excited to try new tools like this. The idea of having an intuitive way to save a series of steps in a spreadsheet interface without having to use macros or use R is definitely appealing.

I opened the March Madness example linked to on TC. I don't really understand how to trace what it is that has changed from one step to the next. Is there a simple way to do that? Is there another example you would recommend to understand how the steps work?

>there are good, scientific reasons people say "eat lots of whole grains" and it seems very odd to condemn them without taking those reasons into account.

Do you have sources for that that don't rely on correlational studies?

Serious question, not snark. I'm curious.
People behave economically.

People take risks according to their preferences and perception of risks and chances. So, if they are willing to invest and hold bitcoins, they will be holding some amount which balances chances and risks accordings to their perception - this can be as little as 10 $ or tens of thousands of dollars.

Behaving rationally, they do not take efforts and go lengths to buy bitcoins, only to spend them for something they can buy otherwise more easily and with less hassle.

But, Bitcoins also have advantages in costs, speed, safety and privacy. For example, due to creditcard costs for backcharges etc., goods paid in bitcoins could be 5 % cheaper. Because margins in online trade are small and costs matter, this is a very significant advantage. Also, time matters.

Once these savings are larger than the cost and effort needed for refilling their bitcoin wallet, people will use them for sure.

I can recognize a lot of stuff I used to do when I was 16 and owned that kind of website. A lot of linking to send traffic to other websites who would send traffic back. A lot of fake traffic through iframes, and often through <img src="url" width="0" height="0"> because iframes fake traffic would be protected against. A lot of exchange with that kind of websites.

There was a huge bubble.

Also those websites gives you what you want to see. We all started doing porn, but the most clever guys understood that you had to post more. Gore, Fights, Shock...
But this allows an average well-informed SF employee to invest $1,000-2,000/month of his/her salary into any startup they like - hardly a life changing amount. See it as a Kickstarter on steroids. At least this gives us a chance too to invest in the next Dropbox and Airbnb.

These aren't "ordinary" people? This model's only barrier to entry is the $1k it takes to get in (AFAICT) its not limited to "well-informed SF employees".
The initial deflationary period is important for adoption. But in the long run, increasing scarcity of coin could jeopardize the health of the miners. Bitcoin has a transaction fee structure to handle this, but taxing transactions is hardly the way to get people to adopt your currency. Also, BTC and other fixed-supply coins suffer from early-adopter windfall effects. The early miners of bitcoin may own a significant fraction of the economy.

I'm devising a "Friedman Coin" or "Free Coin" to fix these issues. If you're interested, drop me a line.

"You cannot seriously bandy about the concepts of supply, demand, and market (equilibrium) price, concepts which form parts of basic economic theory, and then throw out the standard economic definition of value."

There is no "standard" definition of "value:"

http://www.econlib.org/library/Enc1/NeoclassicalEconomics.ht...

Your claim that value is nothing more than "demand" is not universally accepted among economists. I did not throw out any definitions; all I did was point out that value is affected by both supply and demand, which is a straightforward neoclassical interpretation.
Not supprised and happens, almost as good as cut and paste admin flaws that happen. Still the humour of a program in C that looks for insecure routers and uses strcpy is not lost on me :).

True of many equipment using default user/pass combo's, perish the thought they forced a change upon bootup/configuration, but that should of been covered by CISCO admin 101 school. AS/400's, heck anything with default accounts can end up with those accounts left, the sight standard user admin acocunts installed and maintained to password standards with the out of the box ones still there.

Then we worry about home routers with default admin accounts - oh the humour of it all. Some managment will think CISCO - thats expensive so it is more secure and they can get cheap staff in. Well you see what happens then.

If you're looking for growth, it's better than the stock market where the deep pockets have already gotten in early and eaten up all the speculative value in promising ventures.
the irony of this comment coming from Mr. Integrity is not lost on me
Let me help:

> For example, during one of the talks on Sunday a woman took a photograph of two men who had been joking to each other by lightly sexualizing some computer jargon and she tweeted about it citing their remarks as offensive

Jokes along the lines of "my dick is pythonic" may be hilarious among your python-hacking friends, but saying it in a space where you don't know who's listening and what they've gone through was not a good idea.

> On the offensive remark I have very few details, but those I was given was that it was something like “you’re the hottest.” That doesn’t sound very bad to me but I suppose that could have been a polite paraphrasing of what I said

There are many women for whom that's the low end of the sexual harassment they endure. It is pretty tame, relatively speaking, but another straw on the back in a culture that condones much worse.

> Gray areas. Guys are pretty likely to make dick jokes when in the company of like-minded individuals, how far from conference grounds should they be before that becomes okay?

Speak for yourself. I find it horribly inappropriate in anything approaching a professional setting. Basically, you seem to have limited perspective on the other half of the population, and a large part of your own. This is a great chance to learn.

Interesting question. My experience has been that these personality traits have more to do with entitlement than intelligence and that beyond a certain level they drop off. Maturity also helps. This doesn't really help deal with it, other than to suppose that maybe it isn't a big problem. I wonder if other people have the same experience.

It's hard to quantify, but it can be non-trivial. See my other comment about the one internal tool we might release. Part of the reason it hasn't been released yet is exactly because it needs work to make it "releasable". For a tool which is strictly used internally, I might take some short-cuts or make some compromises that I wouldn't want seen in any code I release to the world. I know FUCIT has hard-coded file paths, hard-coded usernames, pages which are not "built" but render using Grails scaffolding (and look pretty hideous), and all manner of bugs that I don't care about, or aren't serious enough to justify fixing right now. I'd want to fix all of that stuff before releasing that thing to the wild, just as a matter of professional pride. If I sat down and focused on it intently, I could probably get it into releasable form in a couple of weeks. But justifying that much work is hard to do right now.

Oh, and there's also no documentation, so that would need to be done.

Anyway, the point is, taking something internal and prepping it for widespread release can be a fairly substantial undertaking.

I'm still completely in shock to hear the news.

When I ran the first DjangoCon back in 2008 I was just a 23 year old programmer. New to everything. All the people there seemed like superheroes to me. I was honoured to have met Malcolm and to listen to him speak. He was a massive inspiration to me.

Malcolm worked incredibly hard for the Django community and we're all better off because of the commitment he made.

Thanks for being an awesome guy, for your dedication and for your knowledge. We'll all miss you :(
They have stayed pretty true to it, they bought it about a year ago and made it free. It used to be like Tower or Cornerstone where you had to buy it for $29 bucks or something. Have liked it since then and was a much better client than MacHg at the time for teams. Glad Windows is getting this, I use TortoiseHg and Git there currently but will probably switch.

Last time I checked only a handful of file types were editable in Drive. I can edit source files in Dropbox but Drive simply downloads them.

Drive's file manager is also very limiting while Dropbox's feels much more like a desktop experience. I can archive, unarchive, copy, paste etc. with ease.

there was literally a company called e-gold, which was sucessful until they were shutdown.

http://en.wikipedia.org/wiki/E-gold#Crime_and_fraud

inevitably, if a competing currency pisses off the governemnt, it will be shutdown if it is centralized. it isn't really possible to do decentralized gold-backed currency (except perhaps, ripple may solve this).
Always a possibility. Though that wouldn't change the short term effect on students, since the "dumping" did have the effect of lower prices for them.

Of course :) I just think that doing it from a HTML table is best practice and it's always nice when a library promotes these. Most developers simply go: 1) I want chart 2) Chart needs JSON 3) I give chart JSON

1. Or – third possibility — many people have recently raised their expectation of the future value of the Bitcoin economy. If you're familiar with stock trading, this is analogous to having a high P/E ratio.

There is a lot of uncertainty here. Intelligent, rational people disagree wildly on the future of Bitcoin. There are all kinds of risks: legal, technical, and competitive.

If the exchange rate crashes, and takes a long time to recover, you'll feel justified in calling all buyers "speculators feeding the hype machine", when in actuality many of them were simply wrong, or early.

2. False dichotomy. Some people are speculating. Others are using it to exchange value. Inventions don't need teleologies.

Your concern, if I'm understanding you, is that speculators are harming Bitcoin's potential as an alternative to the current economy. I wouldn't worry about that. The exchange rate is either going to $0 or $1000+, and the behavior of the community short-term isn't going to affect that.

Obviously, I'm long Bitcoin. See this blog post from 2011: http://andrewbadr.com/log/10/bitcoins-and-why-im-buying/

Designing for a Responsive Web Means Starting with Type First
Hi Neophytos! Love that you took the effort to take a designer-favorite forum and turn it into a mobile app for easy access! However, because this is for designers and design is something that we value rather highly, a lot of us feel that effort should have been made towards creating a more visually appealing UI and that we cannot justify purchasing a product that should be free until the UI is improved upon. Maybe drop the price to free? Or hire a designer? If you don't want to hire a designer, there are many UI kits available for free that designers put out there (such as the Flat UI Kit from designmodo). Happy to help you guys on the design front!

If you'd like more feedback, you can check out the thread on DN. Some of it is harsh (sorry), but I think if you were to improve the UI, we'd be more receptive towards purchasing and using the app:

Poll: Do you still use Freshmeat (aka Freecode)?
In days of yore, freshmeat.net was considered a central and highly important (and influential) website in the F/OSS world. Projects announced new releases there regularly and it was a great place to keep track of "what's new"? The question is, do you use Freshmeat (now renamed Freecode), either to announce releases of your own projects, or to find out about new projects?
Of course I do, who wouldn't?
I used to, but not anymore.
What the heck is Freshmeat???
People don't lose their 1st amendment rights simply because they are organized as a corporation.

This assumes that any speech or political contribution by a corporation is automatically assented to by everyone who is associated with the corporation. Ask the employees or shareholders of a large corporation how many of them agree with using the corporation's money for the campaign contributions it makes.

If people want to express their individual opinions, they can express them individually. If they want to express opinions as a large group, they can all sign the same letter or petition. Using company money to do things that only some of the company's owners or employees would assent to is not "free speech"; it's misuse of company money. That used to be called "embezzlement", not free speech.

The law can't favor free speech for some corporations/groups (New York Times, MSNBC, UAW, etc.) but not others (non-profit groups like Citizens United).

I agree with this; I don't see why the New York Times should get any special privileges because it's a "journalistic organization". But that just means everybody should have to abide by the same rules; it doesn't mean the rules should allow corporations to do things with company money that many if not most of their employees and shareholders would not agree with, just because those things happen to be "speech".
I can't break it to you any more easily than: You are flat wrong. Segmentation is micro-economics 101 and is an expected company behaviour.

Perhaps I can explain briefly. The "deserved"(sic) price is a value where both buyer and seller are comfortable doing business. In most cases, this is not a single value, but a range of values. At the minimum threshold the seller turns comfortable, and then there's a range where the transaction is possible and at the maximum the buyer turns uncomfortable.

Now, while for a given product and fixed seller, the minimum value of the agreement range is fixed, the maximum is dependent on the buyer. Yes, it is possible to sell all products at the minimum, but then you are giving all shared value to the buyer. Even if you are aiming for fairness, the transaction should occur at the middle of this agreement zone (the buyer buys at less than his maximum price, and the seller sells above his minimum price).

You could tackle this difference between consumers on a case by case through individual negotiation. Obviously this is not practical, so the next best thing is segmentation.

You may think this as unfair, but this is a result of seeing a half-empty glass. Segmentation allows for a company to subsidize "cheaper" products using "premium" products. If a cheaper product covers variable costs (but not fixed costs), and does not cannibalize the premium products, segmentation allows for prices below what would be possible if the burden of fixed costs had to be assigned to the cheaper segment. In industries where most of the cost is fixed (as in semiconductors), segmentation is key to achieving large volumes without compromising the ability to profit.

I don't know that you can call deflation an inherent flaw. In most econometric schools of thought, the debate between deflation and inflation boils down to expectations, making predictability more important than either tendency. IE Actors knowing what to expect from the money supply, eliminates some of the uncertainty that drives volatility. Predictability gives actors the opportunity to properly hedge protecting against the negatives normally attributed to both inflationary and deflationary currencies.

With central banks, it just became accepted that when dealing with unpredictable economies, the tendency to inflate was less dangerous than the tendency to deflate and thus why most banks will err on that side when making policy decisions. There are some great historical examples where banks organized mass deflation (I can't find one right now, but the one in my mind involved the entire country dropping zeroes from the end of their notes) and by making the change predictable, they were able to avoid many of the harmful effects.

"Why is deflation bad?"

Deflation is bad because it makes loan repayment more difficult during both recessions and periods of growth. In the extreme, deflation will worsen recessions and hinder expansions of the economy.
We absolutely do.
Unfortunally for us not in USA, be part in the bitcoin stuff is still harder. Can't be buy easily at all..
> It's not unrealistic that Satoshi could own 2% or 3% of all the money that will ever be made. That's a problem.

Not really. It might offend someone's sense of fairness, but it hardly has an impact on whether the currency will achieve adoption.

It's really only behavior on the margin that matters.
I've always liked the idea behind bitcoin (decentralized cryptocurrency), but I think ultimately it will serve the role of "specie gold" with something more useful on top for transactions -- either book-entry accounting at a wallet provider, or ideally some kind of blinded token system.

Bitcoin has numerous inherent deficiencies as a transaction system. It's also not a great store of value -- you ultimately want something equivalent to debt or equity in productive enterprises, rather than a commodity, to hold the majority of wealth -- that's the whole point of fractional reserve banking or mutual funds/investment accounts.

It may or may not be an ideal unit of account. Right now, USD is undeniably the default unit of account, and even bitcoin vendors tend to price in USD (with the runners up being EUR, JPY, etc.; other fiat nation-state currencies).

So, some kind of blinded token system where issuers of blinded tokens hold public amounts of bitcoin, and where the tokens are redeemable upon demand for bitcoin ("specie") would work a lot better than trying to shoehorn transactions into bitcoin directly.
