> What's the best and easiest exchange to get into? Lets just say to start buying bitcoins?

I recommend Coinbase. It's what I use personally. Bitstamp is also good I heard, and has the most volume for people in the U.S. Btc-e.com has a really good community, but it seems more difficult to transfer money into.

> also, what's the best API to use to start charging my customers with bitcoins?

Bitpay is the best, I believe, although I have no experience with it. It's also received VC from Peter Thiel.
Nope, just a mockup. We'll make the real one look pretty :)
Ask HN: did you ever implement a toy processor?
Did you ever implement a toy processor? Was it from scratch or were you given pieces to complete? Do you think it was worth the effort and did it help you become a better coder?

I'm asking this because I feel there isn't any easy way to write/debug and run fpga projects. I would like to change this, and I'm wondering if others feel the same?
I'm not sending anything racy or inappropriate. They're just not photos I would want on my facebook, which is very much a "curated" representation of myself.

It's great for photos that are badly-lit, or inane, or make me look unattractive, or related to some sort of in-joke, or that only make sense in the moment. I wouldn't be mortified if any of them were released; they just don't make sense on my carefully-tended social media profiles.

The draw, at least for me, is not covertness or secrecy. It's a form of expression that doesn't demand the "does this really belong on my public profile?" test, which is really liberating.
i don't think thats a fix at all.

i still think it should be possible to revert a merge with a single command and no flags.

the volume of questions about this on stack overflow and co. and the variety of answers, some of which i'm sure i tried and found not suitable, suggests that this is a real user experience problem.

alternatively their should be a decent ui solution to hide this stuff and it should be packaged with git in some friendly installer somewhere (not SourceTree which although the best of the bunch I've tried, was of no help to me when i had this problem and has a huge stack of usability problems vs. e.g. p4v which frankly everyone should rip off because i'm sure its why perforce is still even a thing aside from support contracts...)
> one of Google's biggest strategic successes was their ability to convince an entire generation of engineers that they were something other than a company

Interesting. Would you statement hold if I replace Google with Apple, and engineers with consumers?
I don't think so. It's more that I click on an email, the 'Loading...' label shows up but it's not doing anything.

I'll offer you a game: A fair coin, heads you win $2^n (where n is the number of coin flips) and get another coin flip, tails you pay me $1,000,000 and get no more coin flips.

There are bounds to the rationality of expected value theory.
I made a collaborative drawing application
I made a collaborative drawing web app with HTML 5 canvas and web sockets. It's still a WIP, with features like multiple rooms and actual logins coming in the future.
i was too strong with 'unrecoverable'

'unrecoverable in acceptable timescale with acceptable resource' would be accurate.

specifically i found it difficult to undo a merge and found that i was in a team where people had decided to use tools they didn't know enough about to have been using at all.
This is really cool. Amazing work.

I am looking at running my own mail server out of a Linode instance. It would service a number of our domains and serve to migrate from having web and email live on the same machine at other VPS's. I want to have email serviced from a dedicated instance that does nothing but email for all of our sites.

This seems like a better overall strategy but it's been hard to get motivated to get it done due to the amount of work this represents. I have not studied this guide in detail yet but it seems to really take you down the path step by step very nicely. Thanks!
Not if it is a potential safety issue though right?
Please cite examples of technologies that kids embraced and did not become successful.
Yes. Apple is also a company. Next question.
I clicked the link expecting to see security/privacy arguments (perhaps a HN bias?). Instead, I saw arguments against Gmail's best-in-class web-interface. The combination of keyboard shortcuts, labels, and filters make it the best. Having used Fastmail, it does rival Gmail, but only if you are an advanced user willing to put the effort into making it fit your use case. The reason I am slowly switching away from Gmail is founded in security and privacy considerations, somewhat better control over my own domain, and I think that Gmail's move to a the tabbed inbox was failure in large part, and mixes junk with legitimate mail in my inbox.

FWIW, I've used Gmail for 6 or 7 years and Fastmail for 1 year.

Edit: clarification

Not true, the ":(" email is much much worse.

>>20% time barely existed and Google

I wouldn't be surprised. And its not just 20% projects, I'd be surprised if any smart person would like to do hacknights, hackdays, weekend projects for the company.

Such initiatives have always been the execs/VP's of way of saying 'Please someone do my homework'. If you have a leader who is clueless about the direction the person wants to go or projects the person wants to chase. The easiest way is to call for such initiatives, choose a mediocre project from it(You don't want great projects to make the programmers more famous than the managers). Once such a project is chosen, you will be kept busy forced to hit the deadline working 100 hr weeks. While the VP will be pushing his days sleeping on the job.

What happens at the end of the year? Best case- You will get a passing mention at some event. Mediocre case- A congratulation email from a team. Worst case- Punished for making some mistakes.

At the same time the VP/manager/Director will likely get promoted, receive a fat bonus or raise for 'developing a culture that fosters innovation'.

If you are good enough to work on a great side project, do it at your home. And for yourself.
"The Silk Road shutdown resulted in brief, but shallow sell off and subsequent rebounded within a few days. This event showed the world and governments that illegal activities were a very small fraction of the transactions taking place on the bitcoin network."

I would say it showed that Silk Road was a small fraction of all BC transactions, but that still doesn't speak to the total amount of illegal activity going on BC.

That said, it does imply to me that either:
(1) The total percentage of BC transactions being used for illegal transactions really is low (as the article implies), or:
(2) The remaining entities using BC for illegal purposes are confident that what happened to the Silk Road won't happen to them.
It's possible that when you were doing this things were different, because even in the last year or so it seems like git has become a lot less esoteric in its interface, but the man page for git revert currently explains a fair bit about how to use it to revert a merge commit. Basically you just need to specify which parent (of the merge commit's 2 parents) is the one that should survive the reversion with '--mainline'. This seems intuitive to me, with a maybe deeper than average understanding of git, though the rather more involved process of undoing the reversion is less so.
Arguably, those selling pre-paid contracts to run miners for you (and to a lesser degree, those selling machines) are shorting bitcoins. I've heard tell that there exist more derivative-y derivatives, but I've been assuming the counterparty risk is unacceptable.
Ehh, I feel like this is written from the perspective of the investment industry, who foolishly pumped money into the incredibly-overvalued Facebook IPO.

How was the Facebook IPO overvalued? The stock has increased 28.9% since the IPO.
Microsoft had a good reputation in 1997?
Veterinary applications come to mind, because both the portability and the price point are a big issue, and the standard in most situations I've seen is either no ECG or at most 3 leads.

Ask HN: Good site to test / try out many APIs interactively?
My job requires me to use many third party APIs. To compare three APIs (i.e. payments), it normally takes hours to set up just a hello world for one API. Just wondering whether there is any good site allowing me to test or try out many different third party APIs. Thanks.
Hey Craig, speaking on behalf of the docker project: we are busy filling the "docker gap" you speak about. There are currently many businesses aspiring to offer infrastructure to docker users. What we're doing is giving them a way to integrate directly into docker itself, so you can "docker run" straight to the provider of your choice, either from the docker command-line or remote API. All with minimal risk of lock-in.

You might also be happy to learn that some of the talent behind Picloud is now part of the Docker team itself :)
"How many of the products and services that you use every day were created or first used primarily by people under 25?"

And the author goes onto mention how Google, youtube, twitter, gmail, pinterest were never targeted under 25.

Maybe so, but under 25 were certainly the early adopters of them.

The author failed to make a decent case for his argument befitting of the link baiting headline.
I was never illusioned about Google in the first place. This is not disillusionment. I just never expected them to turn into Microsoft.
Personally, I like http://osrc.dfm.io simply because it provides way more detail and insight into the user. Just my opinion though, this is still pretty cool.
yes, but i also i mean configuring it. its not just that i don't know how to drive the other car, but to make it drive in a way which allows me to reach my destination i need to make changes to its configuration - rebuild the engine might be harsh, so lets say adjust the timing belt instead... or change my tires or something. analogies suck.

learning curve is important for tools. the biggest problem was that (before i was even there) someone decided to use a tool they didn't understand instead of a tool that they did. learning git as i went along turned out to be a dangerous path compared to learning svn, p4 or hg as i went along - especially in an environment where everyone else was learning as they went along.

i regret my initial harsh wording because it really isn't broken and in many respects its a fantastic tool, its just poorly designed - and this is very obvious if you look at any of the help pages - there are very few commands which perform common tasks without excessive options. i don't want to configure my tools that much when i don't need to (i.e. when other tools don't need that and provide the functionality i care about). implementation details shouldn't pollute my user experience.

so, how do you revert a branch commit? every answer i've seen required considerably more knowledge and effort than any other source control solution i've used.
Er, "not the core feature" seems clear enough.
So if you do use FBA.. Tag everything?... even the new shrink wrapped stuff... Then you can verify if it was yours or not.

Oh this reminds of recent startup-conf, where health was(or should I say is) the next big thing. Premium-VC investor on stage was saying that if the product is regulated(=medical device classification) then they are not interested.
Nice job! Question, are you guys using an API so users can share their contributions/writing potentially to other platforms?
Just found out some numbers do exist thanks to Survata: http://survata.com/blog/is-snapchat-only-used-for-sexting-we...

Their conclusion: a smaller percentage of Snapchat users use the service to sext than text-messaging users.
Globalisation of western politics? IDK but I feel like every single country is trying to emulate each other; Particularly America. I personally would like to leave but because of the absurd immigration policies of the countries I'd prefer, I cannot afford to leave or scared to go through some arduous transfer.
Why does everything have to have this bureaucratic boloney in the way?

I just want to be somewhere that doesn't have some group thinking they are at war with some people for some reason. So they then can repress/punish/victimise them for some form of gain (power, greed, jealousy, stupidity, etc). All the while they do this under the guise of their morality to protect their people.

A man can dream.
Crowdfunding should be free, pageviews, editor needs to be like penflip, collaboration like social github, dedicated ircs, all billed by dedicated storage standards. Focus on the real service: publishing to multiple bookstores, ISBNs and collaboration.
Both awesome links. Thanks!
Auditors Say Airport Checkers Not Effective in Spotting Terrorists
yeah, i feel like this is almost certainly the case. that man page was absolutely my first stop when i got the error message and looking at it now i can't imagine how distracted and stupid i must have been to have missed all of that information. its a weak argument, but i have never struggled to learn anything when provided sufficient information. usually much less than that is enough...
Usually when I try to nap, that's all it winds up being -- me laying there thinking, and eventually giving up on the nap.
I know of at least one YC did fund and for various reasons including a co-founder getting divorced, the startup failed before YC Class was over. The cost of licensing media right was also a factor.
Thanks for your response.

Did you like the tools you used to test your vhdl? Did you run the code on a fpga and did you find it easy to do?

Do you wish you could demo your processor to anyone using a javascript simulator?
There is an incredibly suitable use for bitcoin: as an exchange currency. Its decentralized nature makes it extremely attractive to smaller nations as a way of maintaining liquidity, enabling trade, all while not propping up another nation with competing interests by making their currency arbitrarily valuable. Its digital nature makes it attractive to currency trading markets for purely logistical reasons.

You are probably right about the median case, but I say there is a small chance of a >$10M value for this reason alone.
The article mentioned MySpace. I'd add AIM which was killed by SMS.
I completely agree that reverting a merge in git is painful (painful, that is, in figuring out the parameters to pass to git revert).

Let's say this is your scenario:

d Merge branch 'test'
|\
| c-test Test Branch Commit 1
b | Master Commit 2
\|
a Master Commit 1

And let's say you want to revert d, the merge commit. You would do this:

git revert -m 1 HEAD

Now your history looks like this:

e-master Revert "Merge branch 'test'"
|
d Merge branch 'test'
|\
| c-test Test Branch Commit 1
b | Master Commit 2
\|
a Master Commit 1

-m, or --mainline is the key here. Git needs to know which parent is the appropriate one to revert to.

As the d-b-a line is the leftmost one, its parent number is 1.

Let's say that, instead, for some reason you actually wanted to rely on the d-c-a line as the basis for the commit, effectively throwing away the changes presented in commit b. You would do:

git revert -m 2 HEAD

That said, you almost always want -m 1. And that said, this is how I understand merge reverts to work, but I've only had to do this a few times, so take that with a grain of salt.

--

With all that said, I completely agree with you about the frustration in trying to figure it out, even with SO. This is exactly where some nice porcelain sitting on top of git could make things much simpler.
Toy Story: an immigrant entrepreneurial journey in America
I came here to say just that, I wonder how many are just inactive examples of western oppulence.

Mine were at first but now I have two that are both in active use, a surveillance camera and a deaddrop.
Blogging is still quite popular, just in a different form and platform. Whatever you might have shared can now be shared as a FB post, Tweet, or Tumblr.
Thank you for sharing this! I internalized some of these lessons from my own life and it has made me feel a bit better about similar conclusions reached.
I'd quip that the fact that the author fails to make a decent case for his argument is befitting of an article that uses a link baiting headline ;)
Yeah there's not a lot of tooling for it. I recall writing my own to analyse a disk image to find traces of an intrusion, so its possible if you put in the leg work even for modern complex FS that do stuff like store small files inline in inodes.
Interviews with Interesting People - Paul Graham Interview Request
Hi Hackernews,

Long time fan of this site and its members projects. Love following the growth of all the startups.

I've recently started a blog www.interviewswithinterestingpeople.com, to settle various curiosities of my own. So far I have interviewed two top NASA scientists (one a Nobel prize winner), a legendary Brazilian rock band (I live in Sao Paulo), a paleobotanist, and UFC hall of famer Royce Gracie. Others coming in the pipeline too.

I think it would be fascinating to speak with the one and only Paul Graham and pick his brain about business and life.

I figured posting here might be a good way to reach him. Or if anyone could put me in touch with him directly, that would be awesome. I'm sure he is extremely busy, but you never know, he might be able to squeeze me in for a ten minute chat some time.

Any help in reaching him would be greatly appreciated.

All the best,

Ross.
I think using the "live" domain is a better branding strategy for MS. That said - I recently opened an account there & it's pretty slick.
That might happen if their privacy/security systems fail and everybody's dick pics are exposed. They don't store data and probably actively purge it, but they might be eavesdropped.

That's almost certainly already happening, though.
If I'm going to switch from Gmail, and bother with the switch, I'm going to make sure it's for one that's damn secure. I do want to move away from Gmail, too, but only because I know Google will never offer end-to-end security to Gmail. Most, if not all of the ones you mentioned won't either.

So I'll just wait a little longer, until something like Mailpile or some other usable e-mail service using DarkMail protocol or something better comes along, before I switch.

Do I think Gmail's UI could use a major overhaul? Sure. But I'm not going to switch because of that, after using it for years. But as I said, I would switch for something more secure.

Outlook would be the last e-mail service I'd ever switch to. They even gave NSA pre-encryption Outlook data [1], according to Snowden's leaks. That's beyond unacceptable, especially when they promise their users "security and privacy". Security and privacy are obviously just a joke to Microsoft, that's only useful to them in TV ads.

http://www.theguardian.com/world/2013/jul/11/microsoft-nsa-c...

Here are the more important bits about Outlook:

> Outlook.com encryption unlocked even before official launch

> Microsoft helped the NSA to circumvent its encryption to address concerns that the agency would be unable to intercept web chats on the new Outlook.com portal

> The agency already had pre-encryption stage access to email on Outlook.com, including Hotmail;

> Microsoft also worked with the FBI's Data Intercept Unit to "understand" potential issues with a feature in Outlook.com that allows users to create email aliases

> Within five months, the documents explain, Microsoft and the FBI had come up with a solution that allowed the NSA to circumvent encryption on Outlook.com chats
Of course kids are good predictors. They have time and enthusiasm to discover something new that will allow them to communicate, alternative channel. When it becomes mainstream, they will leave, like they are leaving fb.

Does SnapChat is really worth 3bn or more, nobody knows for sure.
There's any number of controversial bills that could trigger a Double Dissolution. The near doubling of the debt ceiling is one, though I expect Hockey to capitulate and take the 400 billion option.

Clive Palmer's senate team are the ones to watch as they will be key in blocking the passage of any supply bills.
Dog bites man.

Are we supposed to be surprised at this? Appalled? Impressed? Isn't it normal for countries to spy on each other? What do we think intelligence agencies do?
> "Meanwhile, its interface is as stale and frustrating as ever"

The UX redesign from a couple months back was definitely one of the triggers pushing me to look for alternate services.
The complexity of software doesn't preclude standardized "building codes." Obviously the codes would have to be just as complex, but software could be used to check that those codes are met. It wouldn't be perfect, but current building codes for physical buildings also have their flaws (every building [vs design] needs to be physically inspected by a person [much easier to exploit than a machine]).
how does this address any part of my rebuttle? You said you're not the demographic and don't understand why it's popular, thus the service is a 'boy-band' equivalent of the startup world.
That's a silly hand-wavy thing to say that doesn't reflect how Snapchat is actually used.

Although it's trivial to take a screenshot, the sender receives an alert telling them which friend took it. Given snapchat is used for sharing pictures with your close friends, that puts having your Snapchat made public in the same probability range as having your mobile phone hacked and pictures posted online. Sure, it happens, but that's a risk people are obviously willing to take.

Snapchat provides a mechanism for trusting your friends now without needing to trust them for infinity.
>Outlook interface is the worst.

I haven't had an issue with it, and I've been using Outlook.com pretty much since it came out. Before then I was using the Windows Live Mail desktop client and before then I was using Gmail.
The first and foremost thing to do is to understand your target audience. Once that is done, you have to figure out the competition and where does your app fit into the whole scheme of things.

Once that is done, have a good marketing strategy to pitch your app for the appropriate audience. For this process, blogs such as LH come into picture (if you know that your potential users "do" follow those blogs). Investing a little in SEO and promoting on FB is also not bad option.

Also, the success of the most apps depend on the first impressions, usability and word of mouth from peers :)
Playstation 4 Launch: 24 Hours of Playtime
How do you think this would affect Snapchat?: Apple or Google adding a self-destruct feature to text/picture messages.

Interested in getting some opinions.
I'm surprised at the negative feedback Outlook is getting on this board. Have you tried Outlook recently? It's very good.

Compared to Google's rather cryptic UI (which has gotten even more cryptic over the years), Outlook UI is refreshingly simple and clear.
And now that platform have shifted to Snapchat, but FB, TWRT, YHOO are mostly still in business.

A lot of fast growing start ups make amazing places to work, because of the very virtue of what they are.

They are small, have lots of money, there is no bureaucracy and there are no managers getting in their way of achieving great things.

Microsoft has 95K+ employees and has by and large turned into IBM. Google has 45K+ employees and is rapidly transforming into the next Microsoft.
