This site was created as a response. The article "Are Dev Bootcamps a scam?" had the owners and organizers of development schools up in arms defending their schools. Unfortunately when I asked them to open their books and prove their success rates with all of their candidates, they did not feel they should.

I'm now letting the students and community answer the question of whether or not the schools are a scam.

"90% of the world is using Excel and similar tools to analyze and visualize their data."

These types of statements always prompt me to ask "what is the specific problem you are trying to solve?". Replacing Excel? What is the unique advantage beyond a different UI? I think the real product challenge here is identifying why using a different UI or tool would have ROI for the average business user the author is describing. If it doesn't, why would they switch? What is your startup's tool going to do to increase my profits and justify the investment and switching cost?

I've often found it is the analyst and approach, not the tools that make a huge difference on these problems, and for those who care deeply about tools there are many open source options (R, SciPy, etc). Creating more generic "small data" tools runs the risk of solving a problem customers don't have.
My problem with Open Source projects is they're built on hopes and prayers and not money. It takes funds to make things happen. It takes funds to pay the bills.

Open Source projects like PHP, MySQL, Wordpress, FireFox, OpenOffice are all backed by big companies that make a lot of money and can afford to keep the project alive. A lot of other open source software is just dead, going nowhere, without a plan, no source of income, and the community too afraid of money with a hatred of rich people and big corporations. They're more interested in running the software company "not like Microsoft" than making it successful and sustainable. I've seen a lot of good OS software die a miserable death because it's owners refuse to make money. So I refuse to waste my time on them.

You can write C in Haskell (I do sometimes, for SPOJ or something) if you really want. However, Haskell lets you say that something has no side effects, which is very useful for reasoning about programs.
I think you need to strike a certain balance: for longer stretches of wire and higher wattage AC will work better. What doesn't make sense is building tiny switching power supplies into every lightbulb.

I was planning to use a power supply for every group of lights — e.g. one for the ceiling, one for under-cabinet lighting, etc. That way you don't have to run long stretches of wire with DC, and yet you don't have to build lots of tiny low-efficiency converters.

1) If I held xxx bitcoins in a foreign exchange, having bouhgt y% of those xxx coins there; and transfered z% of the coins there; then later turned into cash w% of those coins and withdrew it to my USA bank account; then transfered the remaining xxx-w% coins to my local wallet; what do i do about taxes.

2 ) additionally, of those xxx-w%; i lost a password protecting all of the coins and paid 10% of xxx-w% (measured in bitcoins) for someone to crack the wallet passphrase, then what do i do about taxes?

3) then, my computer got hacked and someone stole the remaining bitcoins leaving me with 0 on my local machine and n (where n is << xxx-w%) in a different, us based wallet,
then what do i do about taxes?

to be clear, i have 3 questions

what happens if 1) happens. what happens if 1) THEN 2) happens. what happens if 1) THEN 2) THEN 3) happens?

edit: the z% of coins transferred into the foreign exchange came from services rendered at a fair market value of `d`
"1. Offers to make partnership introductions that are a waste of time."

This happens over and over and over again. It's compounded by the fact that both of the introduced parties feel some amount of obligation to report the introduction as "super helpful" - and so this perpetuates. Some VCs are much better about receiving honest feedback about the usefulness of these intros (they are, after all people). It's best to set the tone up front a quickly. If the intro wasn't helpful, say so and don't let them waste more of your time.

It seems to work well if you come to an agreement ahead of time that you would like to pre-evaluate any intros before they happen. And don't let them start suggesting a bunch of intros at the end of a board meeting - you've probably got a million other things going on in your head at that time.
My experience tell me otherwise with both of them. It can take from a few days to a couple weeks.
True but these are both transferring gold so that the gold is in a different physical location, not transferring gold to pay someone. I'm sure both cases would much rather sell the gold in place A and buy it in place B, but that's just not possible at this quantity of gold.
This is pretty amazing. Does anyone know how this works?

Basically it was a case where people thought they were being spied on by the NSA, but couldn't prove it. They wanted to bring suit to force the NSA to admit that they were spying. The court said that because they had no evidence they were being spied on, they didn't have standing to bring the suit. Yes, I know, circular logic.
Interesting... I would second adding some hints after n failed attempts. You could just expect the user to go off to google but it'd be a nice touch to get a small hint in-place.
Except that usually grep and sort can read files, or entire directories, which is considered a "side effect" in Haskell.

(Not to mention checking locales to decide how to sort, checking if the output is terminal so that we can add colors, but only if the environment variable says so, and on, and on...)

Its probably because of the narrow definition of treason written explicitly into the Constitution [1].

sorry for the old post, but I did try it and it refuses to activate swap on a non-swap enabled device. Now I assume that you had done that a while back (judging from the hda device) so there are probably now some extra safety checks (good thing too!) :-D well I'm sorry for your loss long ago :-)

Virtually everyone already does that in practice.

Consider the humble savings account. Those accounts may be dollar-denominated, but under the hood they're really a type of security. You're making a loan to the bank at interest - a special kind of loan that you can call at any time, in part or in full, but a loan all the same. The bank then takes that money and loans it out at interest to people who want to borrow money to buy houses cars, whatever.

There is risk involved - the people at the end of the chain might default on their loans, in which case the bank loses their money. Historically, if the bank lost enough money then they wouldn't be able to pay back the money they borrowed from you, in which case you also lose it. Nowadays banks are required to carry deposit insurance, so instead when the bank defaults the FDIC loses their money, but you still get paid. But if enough banks default then the FDIC also won't be able to make good on their guarantee to you, and you're still out your money. Meaning that when you stick your cash in a savings account, it's not really money anymore. It's an IOU - a promise to give you money when you ask for it. Probably.
So Chrome don't recalculate :hover CSS pseudoclass when position of element changes, it does it only on mouse events.
Utterly incorrect. They did not transfer a single dollar. For them to turn those Bitcoins into dollars, they will have to pay more than $0.00. Possibly A LOT more. They may not even be able to turn those bitcoins into dollars for a while, and in all likelihood it will not be $150 million dollars.
> So maybe I'm ignorant here, but did they do the transfer over the Internet, or was it a thumb drive taken out of "cold storage" and handed off to someone else.

Every bitcoin is controlled by a private key. The private key can be put in 'cold storage', but if I hand you the USB key with a private key stored in a text file on it, you have no way of being sure that I didn't keep a copy elsewhere and in a few minutes will make a transaction sending it to some other private key (which you don't have). So unless you trusted me an extraordinary amount, you would immediately want to make a transaction transferring from the private key on the USB to a new private key you generated just that moment.
I'm not a crypto research either, but this paragraph explains basically what keeps the data secure against vault capture:

> Red October is backed by a database of accounts stored on
> disk in a portable password vault. The server never stores
> the account password there, only a salted hash of the
> password for each account. For each user, the server
> creates an RSA key pair and encrypts the private key with
> a key derived from the password and a randomly generated
> salt using a secure derivation function.

Breaking this down:

1. Create database
2. Create user
3. Store salted/hashed user password
4. Create pub/priv keypair for user
5. Encrypt keypair using password and a new salt

If you get the vault, you need the user's password to decrypt their keypair. Trying to crack their password is really hard (they use scrypt). Trying to crack an encrypted keypair is really hard because they also use scrypt (i assume?). Even if it is cracked, all the other encrypted keypairs have a different salt, so even one cracked still leaves all the others to be cracked again.

So even if the same plaintext data is encrypted by multiple people, it'll be substantially different each time because of all the different keypairs and salts.
There are a couple of factors coming together here that require some explanation in order for the individual parts to make sense.

Everything he writes appears backwards because he's facing us as he writes. Hence, someone standing in the room would see everything in reverse.

This isn't a problem because he uses flip teaching, where students view a video of the lecture at home. This only becomes clear if you read the details. The camera he uses to record his lecture does so through a mirror, so the image is reversed by the mirror, not by software.

Also, overlays need not be reversed, because they aren't projected anywhere. They're composited in to the video stream by a switcher.

All of this becomes clear if you read the creator's write up on how to build one. I'd highly recommend it:

I am not an expert, and am definitely bias, but I think (1) is that all gains are deferred until market.

If you're paying a 15% tax on bitcoins mined, then it would stand to reason they would tax you at market, aka, when you exchange that bitcoin for USD.

This is me thinking in terms as bitcoin being a commodity however. If this isn't the case, I'd imagine they could structure it like the structure it like reserves and resources, (http://goo.gl/MkDFNX).

I'm a webmaster for hundreds of mining companies in Canada, and any of them who choose to trade on the TSX or TSX.V need to post this information. I don't know what the tax situation on that is however.
Actually, the important thing is that the court said that part of the reason for its decisions was that there would be an effective remedy in the case that the allegedly-improper spying was used in criminal prosecution, because the government would disclose that the spying had occurred, at which point it could be challenged.

The whole issue of the letter is that the representations made by the government to the Court on which it relied in finding that there was a remedy available at a later point which would be more appropriate were not true.

I think that's a little too black and white back the other way.

Don't get me wrong, I live in python, I create classes on the odd occasion I need them and not before it's definitely required.

That said, there's nothing wrong with sitting down and modelling the problem you're trying to solve on paper to try to understand what's involved. You don't need to implement it that way. Whatever you do, stop and take a moment to think it through.
The other big issue is how hard it is to exchange pesos for dollars. The government is doing all they can to make it nearly impossible for the average Argentinian to avoid the massive devaluation.
This is bordering on blogspam. If you read the actual creator's write-up, there is a LOT more detail.

What is your price target, if I may ask?
That was why I proposed something so ridiculous.
Clapper v. Amnesty International was a case which held that Amnesty International lacked standing to challenge parts of FISA and the FISA Amendments Act. The touchstone for standing is showing that you have actually been harmed by someone's action. Standing ensures that the people actually harmed by an action bring suit, so that people can't sue for theoretical violations of the law.

The Supreme Court concluded that the injury in this case was speculative, based on the hypothetical possibility that a member of Amnesty International was in contact with someone who was targeted. The essence of Udall et al.'s letter is that the DOJ's representations to the Supreme Court suggested that the only way a U.S. person's (e.g. a member of Amnesty International) communications could get collected was if they were in contact with some foreign person who was targeted. Ergo, the Supreme Court's analysis was based on an incomplete understanding of the ways in which a U.S. person's communications could be collected, and therefore an incomplete understanding of how a member of Amnesty International's communications could be collected.

Solicitor general Verrilli must answer Congress's questions. I'm not quite sure what Verrilli's obligation to answer is at this stage. As a general rule, you don't want to ignore letters from Senators on Senate letterhead. Committees of the Senate do have inquiry powers and subpoena powers to force you to answer questions if you don't do so willingly.

Let's see, there are approximately 1.22 trillion US dollars in circulation [1], so that would amount to a massive .001% of outstanding dollars. It may not come from "nowhere", but neither is it such a massively huge amount of money that it would necessarily register. Heck, that hedge fund (Knight Capital?) lost that in about 3 minutes a few years ago...

Nebraska business helps brew up a “bootstrap culture”
here's some data points:

we're located in santa monica / west LA, in the middle of town, and our building had, until last year, had the following options for bandwidth:

* adsl ... $40/month for 3/.25 megabit

* EoC (sdsl) ... $1500/month for 15/15 megabit

* Bonded T1 / T3 ... insanely expensive.

Time warner business class moved in with fiber to the building and now we have:

* cable modem over coax muxed into fiber switch @ roughly $300/month for consumer-level speeds (30/5 megabit). which is what we use right now.

* Fiber to fiber (ethernet switch on customer premises):

10/10 megabit starting @ $1300/month (worse than EoC above)

40/40 megabit $2400/month

1gbps/1gbps for $14,000/month (yes $14 THOUSAND/month.

we pay $400/month at the datacenter for each of our 1gbit/1gbit links w/ a 100 megabit commitment.
ahaha thanks bud!! it's been exhausting because they have so many buzzwords designed to handle counter-arguments, so many people with money invested, and well -- the fact is people are willing to pay for them. What I've been learning is that people will radically alter their lifestyle/views/demeanor when presented with the possibility for a cashout. They kinda get tunnelvision. Plus, there happen to some idealistic tech people who wouldn't mind suffering a minor loss just to see a cool idea work, so they'll keep playing with it even if they lose a couple hundred bucks here and there. It makes for some intense momentum...

Hopefully you will see me posting much less about this and much more about music signal processing + machine learning apps I'm working on :P

Looking through your comments... maybe you want to join me on some anti-Bitcoin venture? I'm thinking of compiling a site providing a detailed argument of why it makes no sense just so that I don't have to keep wasting my breath lol. But I mean the truth is a lot of these arguments are freely available (especially if you check the manifestos written up by some of Bitcoin's competitors or qualified economists). I just feel bad that naive people think it's some sort of tech "investment" and if you don't write negative stuff on the threads their first comment is "Where do I get some?". I bet this is how all pyramid schemers feel at first. Like you're investing in a company, it's just that the company doesn't make anything or do anything... Then Bitcoiners try to say that the worth is in the "ingenuity of the process" or something but then its like... THIS IS AN OPEN SOURCE CRYPTO GAME FOR F__K'S SAKE

The point is... Bitcoin is an international hoax and I get bored at work! I also tend to think that HN is turning into watered-down pseudo tech and Bitcoin is the epitome of that. All these "crypto-miners" who just execute pre-compiled code or whatever... yeesh.

> wait... did anyone catch how he superimposed the powerpoint slide onto the screen/glass/whatever? it's not in the video or the page text.

Yeah, in his construction page, he explains that he uses a video switcher. It's way more complex than it sounds - he's combining feeds from the camera plus a computer into the final output, which is easy enough, but then he needs to be able to see where he's drawing - because that projected image doesn't actually show up on his light board. So he has a monitor on the other side of the light board that he CAN see, but then it produces reflections on the light board, so he starts in with polarizing filters.

If we're going to start suggesting physical activities I'd say Brazilian Jiu-Jitsu and rock climbing are both very chess like in their emphasis on strategic placement/puzzle solving. Your limb placement, your endurance, the way you shift your weight, the current momentum, they're all your pieces and you have to play them appropriately.

I'm a huge fan of both activities because of the combination of mental and physical demands.

The real question around US compliance is how to position Bitcoin holdings in the most favourable light and prove it so that if the IRS initiates an audit then you can provide enough of a trail (e.g. blockchain) to show that you've held onto them for long enough to qualify for certain tax rates and satisfy conditions for capital treatment.

When you refer to "wallets" in your comment above, it seems you're only referring to ones that are on Bitcoin exchanges. I think many people would like to know where personal wallets fall, mainly wallets that are on personal computers running bitcoin-qt/Armory/Multibit.
But which is the cause, and which the effect?
> this transaction was nearly instantaneous

Aren't Bitcoin transaction times generally in minutes?
Those third party fees having nothing to do with bitcoin's simplicity or reliability, but with the amount of the insured transfer, the perceived risk of the failure, and the expected costs and complexity of recovering any losses from either party involved.

Whether it is in bitcoin, CHF, EUR, USD, gold, platinum, Amazon Coins, Zorkmids, yams or sheep skins, insuring a transaction will depend on those factors.
I've just used a bunch of iOS apps that have that effect and I've found that inertia is present in way more interactions than are immediately apparent. Zynga Scroller is a pretty good (pure math!) implementation of it.

Sorry that I was so harsh. I think the marketing copy turned me off a little bit. If this were presented a little less like "here is _the_ solution!" (when so many others have come before it) I would have been less of a jerk :/

I think what frustrated me is that you guys seem to have the right attitude and design to pull it off and I felt like the interactions weren't quite there. So please don't settle for anything less than perfect, no matter what it takes :)

I do want to point out that your design is great and the interactions are a lot better than most of the web stuff that's out there. And it looks like you've spent a lot of time working on developer experience which is great too; impressive for only working on it for two months :)

Building a full production grade website seems extreme, but giving a prebuilt website to a front end candidate and asking them to add a few simple pages or features is basically fizzbuzz type vetting. I also like it when coding "challenges" are timeboxed to say 1-2 hours. This keeps the time expectations reasonable for both the interviewer who has to read a bunch of candidates' challenges and the interviewee who has to do them for (potentially) a bunch of gigs.

The type of coding challenge a company asks (interview questions also) can be one of the most important data points to use to judge a company's culture...
That might work, but it's not clear how all the graphics, image processing, user interface, and dynamic interactivity stuff would work.

Still, would be interesting to try. I have great enthusiasm for what Chris Granger is doing.
It's well-known that you can at least secure your bitcoins as well as you can secure gold, if you use cold wallets.

The advantage, however, is you don't have to worry nearly as much about the security of a transaction (moving it from one place to another)
Isn't this what happens at the Reserve in downtown Manhattan?

Everyone just keeps (a huge portion of) their gold in a single vault. A gold transfer involves carrying gold bars from one compartment of the vault to a second compartment in the same vault.
