> Yes, certain things COULD be automated... at considerable expense to student achievement.

I seriously doubt that letting teachers automatically grade arithmetic tests will hurt student achievement. The fact is that many teachers do that sort of thing at home in what should be considered overtime hours. I would like to hear how automatic grading causes student achievement to suffer.

Likewise, I'm skeptical that it should be solely educators' responsibility to make sure chairs are not being thrown out windows. Letting teachers focus on educating and not babysitting seems like a good thing.

I have the feeling that many people who dislike this have never really worked with a static typing language. I have never really worked with anything except perl, php, javascript myself until a couple of years ago when i got into game programming with Unity3D using C# and Visual Studio. That experience was enlightening, VS (+ReSharper) is like your own personal AI assistant that deeply understands your code and helps you work more efficiently. Today, while working mostly with JS again (node/angular) i sometimes feel frustrated about WebStorms inability to do the right thing because it just can't understand the code in the way it could if JS was static typed. I mean, its still far superior to a pure text editor if you are working with large codebases imo, but i somehow miss the VS experience.

Ideally we wouldn't need this kind of stuff, people would have some perfectly logical approach to evaluating all the vendors, and use their attention correctly. Perhaps it's a game theory problem; if we were guaranteed no one else would use sex appeal, nor would we. The problem then is that big flashy booths are far, far, more expensive then hiring even a half-dozen very attractive people.

But really, it goes deeper than that. A lot tradeshows are a vacation for the attendees, so if throw a fun party for everyone, you'll have a lot of potential customers hanging out with you. This is important if you're in a competitive service business where your competitors are nominally offering the exact same service. Everyone says their datacenter won't go offline, that they'll have proper service, etc. Getting to know your vendor/customer goes a long way in keeping that business relationship when shit hits the fan, as it inevitably will.

As far as the sales info on the floor, of course you need real full-time staff. The temporary staff is just to get people's attention, let them know more or less what we offer, and keep them enqueued while a one of our sales people gets over to them. But for commodity services, everyone already knows pretty much what we're offering. This probably doesn't hold true for truly novel software products that really are different from competitors.

Anyways, if the gender balance changed, and attractive young women weren't enough to get a party going with our customers, we'd come up with something else. But parties seem to be a fairly common denominator, so I doubt that'll change any time soon.
Because transactions are recorded in a public blockchain, couldn't that be a big downside for anyone accepting bitcoin whether or not the coins appear on a blacklist/warning list. If a sending wallet address is associated with some contested activity (e.g. someone getting sued, or indited), I could imagine that those BTC could easily get swept up in the legal actions to unwind or resolve the activity.

This vs accepting cash which is fungible, and would need some other evidence associating the buyers money with the contested activity. At least the resolution activity there would likely be stopped at one level from receiving the cash, but with BTC, you happen to be able to track that one specific coin right through multiple layers of transactions. I can see lawyers tracking all the way out to the current holder of a given BTC.

edit: Upon a bit more side reading, I think the tracability of a given BTC is a bit overstated here.

>"In order of importance: 1. TDD 2. OO-design 3. Increase Rails mastery 4. Algorithm basics (refresher on different sorts, etc.) 5. Learn the basics of one JS MVC framework (leaning toward Angular)."

1-4 are all related. You can learn them all by building something (as someone has mentioned). The problem with saying "learn by building" is how? Nobody ever explains how.

This is how: Learn from whatever resource you learn best (like a cookbook-style tutorial, or a textbook or a video) and then take that knowledge and apply it to the bigger project. If you have your own "how", then go with that.

As for 5, avoid the JS-frameworks for now. Dabble with them, but be flexible enough to try more than 1 out. They're all pretty much in their "hipster" lifespan, so wait until the hipsters move on and then consider picking up one of those frameworks (unless you are a hipster yourself).

You bring up an interesting point. I reviewed a wiki list of Ponzi schemes and assuming that is an exhaustive list I have to agree with you that the generally accepted definition is that you must say you are doing something with the money to benefit the investors for it to be a 'Ponzi Scheme'.

http://en.wikipedia.org/wiki/List_of_Ponzi_schemes

The fact that it doesn't fit the wiki or generally accepted definition of a Ponzi Scheme does not rule out the possibility that it still may be considered one but after spending some more time considering it, it does not look like a true Ponzi Scheme, even if the CEO did directly steal the money and use new money to pay old BTC buyers.

> Just like a commodity then. Where does this "intrinsic value" that you think gold has come from?

Your definition of commodity is incorrect. See http://en.wikipedia.org/wiki/Commodity:

“In economics, a commodity is a marketable item produced to satisfy wants or needs. Economic commodities comprise goods and services.

The exact definition of the term commodity is specifically applied to goods. It is used to describe a class of goods for which there is demand, but which is supplied without qualitative differentiation across a market.”

Gold and silver meet this test because they have other uses (jewelry, industrial, dentistry, etc.) dating back throughout recorded human history.

In contrast, bitcoin – like all fiat currencies – has no value except as a unit of exchange. There's nothing meaningful that you can do with them unless you find someone else willing to accept them – defunct paper currency could at least be used for kindling…
Do you find that you're actually being prevented to talking to a real sales person or engineer at shows? Usually the models are there to keep the queue, since it's rather cheap to hire attractive and outgoing people to do just that. It's probably just a reflection that sending FTEs to shows is expensive, so there might only be a few of actual employees there. But the models should be helping you get to one of the FTEs as soon as possible - that's pretty much why they're hired.
> Basically, I do not condone elections for anything bigger than a small city, and neither should you. They don't work. They don't empower the people.

Since there are empirically measurable difference in how well different electoral systems work in empowering the people in nation-scale polities (see, e.g., Lijphart's Patterns of Democracy), I don't think it is at all the case that they don't work or are an illusion in general.

Its true that the electoral systems in certain large polities (the US among them, but not the only of them) work exceptionally poorly, which might lead to the faulty generalization that elections in large polities are fundamentally broken for those for whom the ones with exceptionally bad systems are the only referents, but that's a flawed generalization from limited information.
Commenting to save for later reading. :)
I think it's far to early to have a meaningful discussion about this. There are so many rumors and poorly sourced "facts" floating around right now. We have almost no concrete information about what actually happened at Mt.Gox and what role Karpeles may have played.
> The dollar is backed by the full faith and credit of the United States government.

It's more accurate to say that the dollar is backed by public familiarity, faith and trust. Some of that trust is in the government backing the currency, but if that were not true, if the government wasn't involved, it's interesting to ask how much of paper money's role and legitimacy could be supported only by public faith and trust in the currency and its connection with the economy. Assuming, that is, that the number of dollars in circulation could somehow be regulated without governmental control (a problem that the Bitcoin system addresses).
>"Earlier today, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack under a 3-clause BSD license.

As an incentive to do this work, we will pay a bounty of $10,000 to the first person to demonstrate to us satisfactorily that they can successfully run Quake III at a playable framerate on Raspberry Pi using these drivers.

That's really a surprise. Broadcom is cemented in my mind as one of the hardest companies to get even basic datasheets out of.

I know the saying is "don't look a gift horse in the mouth", but could it be that their graphics cores are not competitive in pure technical capabilities, so they've decided to compete on open-ness? I'm not really involved in that area of hardware/software.
The reason is two-fold. One is legal/regulation stuff, as jccooper said (for seller account especially). Second is seller protection - if a buyer wants to scam sellers, we can blacklist him based on his ID, so he cannot scam anyone again.

No "regular" currency has any consumer protection at all. If there's a hole in my pocket and all my pesos fall out, they're gone, and ain't nothing the Banco de México can or will do about it.

You might go to the police about the pile of USD that was stolen from under your mattress, but you can do that for gold and yen and USB drives and potted plants, too. The US Treasury, however, won't help you a bit. Even if you send them photos of you holding the money.

It's the institutions that use fiat currencies that have "consumer protection". It's true that the financial system built around everyday use of domestic currency is more forgiving than current everyday use of Bitcoin. But that doesn't really have anything to do with the issuing authority; someone could offer reversible bitcoin payments on credit like AmEx or insure deposits like the FDIC (or SPIC, which is a more appropriate model). And probably they will. Except unlike USD you'll also be able to operate on a cash basis online, if you so choose.

There's not any particular protections for businesses or advanced uses in the conventional system, either. People hack and otherwise steal from banks all the time, and the banks usually just absorb the loss and try to get better. If you have your EUR in an Icelandic bank and they go under: sorry. And guess what: USD deposits in US investment accounts are not government-insured any more than the BTC in MtGox. Brokerages can (and usually do) have private insurance, and probably that will become desired in BTC exchanges. But have your bucks in an uninsured forex exchange and it goes poof? So do your bucks. Sorry, bad luck.

Why do normal brokerages and forex traders (which is more what a Bitcoin exchange is) not fail like Gox? Well, for one thing, they do, you just don't hear about it on HN. The real reason is that those are older systems and have more competence and experience, generally. The "regulators" require some basic competence, but not enough to save you from really bad management. Competence is what prevents a similar thing from happening to other exchanges out there. There's no magic in how the transactions are settled or who issues the currency. (Forex exchanges operate in a very similar environment, and generally work fine.) And you have to evaluate competence in a BTC business just like a fiat one.

Now, there's plenty of questions as to whether a deflationary money supply can work in the long term, and I kind of doubt it. But that's a different question from whether the crypto-currency mechanism, or a non-centralized issuer, works. They seem to work fine--if you pay attention. Running a bitcoin wallet is a bit like running a bank: not for everyone. A crypto that successfully manages inflation to preserve value will work just fine.

This is a step in the right direction. Does this mean that the RaspberryPi can run blob-free now or with one less blob? I don't know what else is needed for the SoC to operate.
I didn't know that – can you send me a link or give me some more context for it? My Google-fu didn't turn up anything.
That is assuming you can "blacklist" addresses before the transaction takes place. Or they could just create a new BTC address.
> It is pretty obvious from the preceding sentences that this is an opinion ...

No, it was stated as though it were a fact that a currency requires the backing of a central authority. It's a testable proposition, and the fact that Bitcoin exists and functions as a currency, and the fact that the present Fed chairperson asserts that the government has no authority to regulate Bitcoin, is the needed counter-citation.

Link:http://www.theguardian.com/business/2014/feb/27/janet-yellen...

Quote: "The Federal Reserve has no authority to supervise or regulate Bitcoin, chair Janet Yellen told Congress on Thursday."

So the original claim is false.
The minimum -- THE BARE MINIMUM -- that any regulator would have demanded of MtGox was an outside auditor coming in occasionally to make sure their books balanced.

If you believe the "slow leak" story, even that threshold was not met.
> "Monoid", to someone who hasn't studied abstract algebra...

Oh come on, man! I can't believe this ridiculous discussion. I'm not lashing out at you, don't get me wrong, but seriously, you think you need to study abstract algebra to understand what a monoid is? Um, I remember one of the first things mentioned in the, literally, first lecture in undergraduate course on calculus was a monoid, among other algebraic structures. Granted, it was theoretical physics, but still, I doubt any respectable university teaching CS would fail to give students at least some familiarity with basic algebraic structures. But you don't even need a university education to grasp this, seriously, stop being afraid of precise terms, there's nothing scary behind them.

EDIT: And to actually address your point :), "intuitive" can only go so far. Sometimes there is simply no intuitive term that can do justice to the concept at hand. As Feynman once said: "I'm not going to lie to you, I'm not going to tell you it's like a ball bearing on a spring because it isn't." Especially in programming I'm not convinced that intuitiveness of a mere label for something is a valuable goal. You can't program on intuition, at some point you just have to learn how the thing really works.

Raspberry Pi Marks 2nd Birthday with plan for open source graphics driver
In our case Paymill approval process was indeed long (2 months?), but the ID verification part was quick and painless. They did require the originals via mail, but it's really not a big deal. The hold-up was with the bank and Paymill fell short in giving any idea of the ETA. They replied quickly, but didn't say anything at all. In fact, 4 or 5 weeks into the approval process, it all looked so bleak that we gave up on Paymill and applied to Braintree. These guys were far more responsive and approved us in a matter of days, but then they also took several weeks to "finalize the setup", so in the end it was a wash between them.

That said, between Braintree and Paymill, BT is certainly playing a catch-up. For one, they just recently dropped minimum monthly fee and switched to simple per-transaction fee structure. Also, their integration requires more work on the backend and overall feels less transparent and "heavier" that Paymill's.

In retrospect, Paymill is not bad at all, but it is not dramatically better than others either. They are all about the same.

Vagrant builds virtual machines for you. Like another computer inside of your computer.

Docker can run within a VM, or on your computer if you're not on a Macintosh (Mac's kernel is...for now...not supported). I usually create a Vagrant virtual machine of CoreOS, which works with Docker very nicely.

Docker is a utility which uses "containers". Docker containers are usually used to run one process at a time (apache or mysql or python or grep or anything, really).

You can connect multiple docker containers to create a functioning app. Running one for database and other one for running your code would a simple example.

Fig tries to make the process of making Docker instances work together easy.

The collapses we've seen with traditional currencies stem from the inherent risks of fractional-reserve lending.

Vagrant is basically a layer on top on virtualbox/vmware that helps you manage VMs more efficiently. It makes it easy to setup your local development enviroments in a vm and replicate the production enviroment for example, instead of installing all the services locally on your machine with homebrew and whatnot and polluting your desktop experience.

Docker is afaik Linux only and uses some kind of container virtualization that makes it possible to run services in a separated virtual enviroment on a per process basis without the need to spin up a full vm with all the overhead. Also these docker containers seem to be portable to different machines pretty easily, making it easy to share enviroments among developers.

Now Fig looks like something to make managing docker containers easier.
