I just launched my first company, Penny. Penny provides a simple way to open an online shop on Instagram. Sellers post a photo of the item along with the price and the hashtag '#paywithpenny'. Buyers can then purchase the item by posting '#sold' in the comments.

It also has an API (http://www.paywithpenny.com/api) so you could pontentially automate shipping (if you have some sort of drop-shipping setup) or even manufacturing for on-demand items such as art prints.

To celebrate the launch, we launched a bunch of koozies into (near) space and are selling them via @beentospace on Instagram. Proceeds will go to charity.
But they still can't make treaties with foreign nations, raise a military, mint coins, or any of several other things generally associated with sovereign nations.
Why does OpenBazaar use Bitcoin proof-of-burn for reputation?
A couple observations...

1 - If you're good enough to be accepted by one incubator, you have an incubator-worthy idea and team. If they go away, another will arrive.

2 - The person forcing your hand is trying to use their temporary leverage over you until you have leverage over them. It sets the tone of the relationship on leverage.

3 - That said, people with lower acceptance rates (whether it's accelerators, colleges, etc) have to play yield games. Harvard yields ~80% of admits so they can wait their time because they are confident of admits, and it won't impact their capacity. Amherst accepts ~40%, so they have to play the waiting-list game. The 2nd tier accelerators have to play waiting list games, and that's what drives this behavior. 48 hours is unreasonable, but a few weeks isn't. (Or having a formalized waiting list too)
Mine was two days (Friday-Sunday). First last and only time I'd seen that hence my reaction.
Perhaps a more useful metric would have been urban v rural populations - but even then Watts engine had only been around for fifteen years (1776 ironically).
One way to fix that would be to list a set of features that hipchats, et al. have that are desirable, and then think of the way to gracefully degrade them to plain-text format.

After that, it's just a matter of implementing few plugins for popular IRC clients that would improve the UI of their respective clients to support those new features.

If anyone is going to start such endeavour, I'm willing to put some man-hours (starting next month) into writing plugins for ERC and Weechat.el, and maybe help with others.

I've seen in a lot of places that Chrome only supported SHA-2 since version 26 (2013). I find this hard to believe (Firefox supported it since 2005) and I can't find a solid reference for it. However I note that this page from 2008, says Chrome supports it https://www.tbs-certificates.co.uk/FAQ/en/476.html (e.g. from version 1)
Speculation is legal and in my opinion very valid reason to use bitcoin. I'm in for mostly speculation and savings reason, as are many of the people who are into bitcoin and I know of. To date it has worked very well for me. Of course everyone has always said that I should not do this, but I'm very glad I did, and did not listen to my girlfriend, accountant and tax advisor.

I also use bitcoins, mostly because it is very frictionless. I actually have always small amount of unencrypted bitcoins in both my phone and computer for small day-to-day online purchases, tipping and clearing debts between friends.

Also the sovereignity appeals to me. I've never experienced any banking problems myself, but I've heard of many. Just the idea that solely me decides how my money moves appeals to me, and there is very limited possibility for anyone to touch my bitcoins.
We only do this because card networks have used their network effects to force merchants to pay for a month of credit for their customers. When merchants have a viable alternative, they'll give customers discounts to use it.
Coinbase business development is kicking ass and taking names.

Why not? Companies make people and partner companies sign them all the time. Why would they not be effective for people?

What if it's a new idea? If the idea is obvious only in hindsight and it doesn't take much secret sauce, then what do you do? You can't communicate at all, so build it yourself I guess.
I seem to remember this being implemented but overlooked it. Thanks for bringing it up. Ideally, that would be the preferred way to "backup" Github repos. Just replace .wiki with .issues or .pullrequests [insert naming convention here].

It would require remembering the specific repositories for each entity but that's a minor inconvenience if they follow this suggested pattern.

The thought of standardizing the data makes sense when these formats change over time, and I expect they will as features or workflow is added. If I backup my private repo today, I would prefer to have the ability to import it 3 years from now if I so choose and not have to "get lucky" with migrating the data format. It likely wouldn't be hard to figure out if the Github backend APIs are as documented as I believe, but this is a pretty big caveat to using any of these backup approaches.
One need look no further than the US to see the folly of a weak federal system.

Missed that. You should expose the signup options on the main page (unless you already have and I missed it). I would have signed up if it was simply a matter of clicking to connect creddle to LinkedIn.
Unfortunately, trying to add true threading to the browser in Javascript is so, so far in the direction of "insane" that it's not an option, so we're sort of stuck in the browser.

Note that I am deliberately referencing that whole set of qualifications: "true threading in the browser in Javascript". Drop any chunk of that and it becomes less insane; for instance, WebWorkers drops "true" and gives a very restricted version of threading. Threading JS in general wouldn't be any harder or easier than threading any other dynamic language in theory (though in general those sorts of languages have a really poor track record, but only in practice, not in theory [1]), but adding "in the browser" is a big problem. Maybe if Servo works properly it will be feasible, but until then it would just be a nightmare.

But I would certainly agree that if you have a choice, such as on the backend server, and you choose Javascript for concurrency, you're making a very poor choice. It just isn't what the language was meant for.

[1]: As near as I can tell, they all tried to retrofit threading onto themselves a very long ways into their development (many years if not decades after birth), and the result- vary from "failure" to "barely functional". However if one set out to create a new language in the dynamic family and made threading a concern from day 1 there's no reason I can see you couldn't succeed. Elixir would be a sort of existence proof. It's the retrofitting that failed moreso than the general idea.
Don't know about OP, but for me it flips the "GWBASIC" switch. I'll admit to my own biases, and one of those biases is based on some design decisions in BASIC. So, right or wrong, when I see old BASIC code I go "ugh". By extension, when I see a language construct that I haven't seen since I last looked at BASIC I also go "ugh".

You're right, I need to get over it and I will. But for the time being a little piece of me whinces when I type "let foo = 3". "OMG, should I be numbering my lines, too?"
We'll see. In the near term, merchants can accept Bitcoin for 0%. Customers can send Bitcoin for five cents, and some wallets pay that for you.

There's nothing inherent in the American election system that requires New Hampshire and Iowa to get the attention they do. That's strictly an artifact of how the parties have chosen to schedule their primary calendars; New Hampshire and Iowa happened to be put first in the schedule, and people started paying more attention to them on the theory that winning these early primaries could start a snowball effect of support in the later ones.

Either party could choose any time it wants to reshuffle their primary calendar and move some other states before NH and IA, or to hold all their primaries at once on the same day. There's just not much pressure on them to do so, so inertia keeps them where they are.

ZFS, Btrfs do this with COW. NTFS (volume snapshot service) and ReFS makes it COW. LVM2 offers a new thinp COW based snapshot that could make this work for any filesystem.

Edit: And Apple's CoreStorage also has some kind of COW capability at least when used for "fusion" drives. And then Time Machine and OSTree are effectively COW as well. The trick here is how to make what's written, read-only and thus write once. Btrfs at least has the concept of read-only seed devices, which can be put together in sequence, but might need some work to make it fit better with this use case.
Your copy could use some proof-reading:

>Forget about looking for a file or a link, in Staply the are always ar your fingertips.
> To some extent, yes, but consider that we're speaking of a numerical differential equation solver. If we make the time steps too large, the program runs fast but the simulation is less realistic. If we go too far and make the time steps very small, we'll start seeing rounding errors in the floating-point processing.

But this just means that the problem needs to be solved carefully; what you've done is state the problem. Look at any textbook on numerical analysis, such as Numerical Recipes, or even something more basic. It will explain how to implement adaptive time-stepping for numerical solution of ODEs.

Here the parameter is not for time-stepping, it's for ignoring nodes in an octree, but you can still mathematically pick a parameter that generates something like a desired level of accuracy, instead of having to specify the parameter itself.

> The reason this class of simulation is numeric is because all but the the most trivial orbital simulations must be performed numerically. The reason for that, in turn, is because of the Three-Body Problem:

You make all of this sound like it's a difficult problem. For a basic ODE solver, adaptive time-stepping is one of the most standard techniques. Most introductory numerical analysis courses in universities cover this, so usually the reason people implement it this way is that they simply haven't heard about it, and don't know that they can look it up in a textbook.
This guy dresses up his reasons in pseudo-intellectual guff. If we follow his reasoning reductio ad absurdum what would be the size of the smallest state he'd like? One with 15 million people? One with 5 million? One with one person?

In reality he just doesn't like the English, specifically English conservatives. The Scots claim they don't like being ruled by people they didn't vote for. But they were happy to vote for Labor for 15 years before this Tory government. Part of a mature society is that you understand that around half of the time you don't get who you vote for.

I'm no great fan of Paul Krugman but he correctly points out that the new Socialist State of Scotland would be set adrift in a world of capital flows it cannot hope to control. http://www.nytimes.com/2014/09/08/opinion/paul-krugman-scots...

David Cameron should never have let it go this far. A federal system would have made far more sense, and not divided Scotland's people and broken a successful union.
What you describe is basically:

Fiat -> Credit Card/ACH -> Bitcoin -> Fiat -> ACH (on supplier).

You are basically adding at least two extra steps in a transaction vs. what exists now. How is this better than what exists now?
I think the poster was trying to say that this article is interesting despite its age, because versioned file systems are still a rare bunch.

I would love to use ZFS everywhere, but sadly I use it almost nowhere. I think that was also parent's point.

Other than that, even considering snapshotted filesystems, I still think venti model is worth discussing because the model is just so different. No deletion, and it doesn't expose a filesystem-like layer. It exposes a much simpler and deeper abstraction.
Is that screenshot the site itself? At first I thought I was seeing some chat app, so Staply must be some sort of browser plugin to connect it all together.

Basically, it looks like Staply is kind of a chat room app with file sharing as part of it. Or not? I was kind of confused.
My criticism is aimed not at you personally, but at the general pattern in (what I consider to be) poorly designed numerical software.
I'm a big sucker for trying new tools like this. But it's also a big pain point to actually switch. The overall look of the page is good, but I think you need to do a better job convincing me the value of the product.

It also isn't completely clear to me what the task/project management does for me. Is it closer to Basecamp or Todoist?

But the biggest knock for me is how similar your time tracking is to Harvest. I'm not one to complain about copying other apps, but it's almost identical, all the way down to the way you weight fonts.

This submission's title "Jack the Ripper identified through DNA traces"

The linked article's title: "Jack the Ripper identified through DNA traces: sleuth"

See the missing word? We're talking about one person's claim, not an established fact. It might be true, it might be false, but misrepresenting the evidence doesn't help.
I'm not crazy about the main photo. It doesn't tell your story.

And curious why you need to have the mixpanel badge at the bottom right? What does it do for you?
It looks like Staply solves a problem, but I don't know what that problem is. In your footer next to the copyright you have "We want to see a world where information is never lost or forgotten." -- is this the problem you're solving? Keeping track of information?

The screenshot hints at a sort of shared folder space for placing things for design review and comments.

I would suggest adding a section above "Take a new approach" that tells me the problem I already have before telling me how Staply fixes it.

Where you say "Private" and mention SSL, I think this is really bare-bones privacy. That's more like "Secure" to me. Privacy implies that you wouldn't sell my data, that you would store it encrypted on your servers, and that your servers are secure. It's more than just the transport layer.

I'd love to share this article with family and friends, but words like "cluster$%^&" tarnish it. While the base demo of Verge doesn't mind, and some would call it prudish to worry about such things, it debases arguments for many whose vocabulary isn't made up of such profanity.

I've seen this more and more with these types of call-to-action letters. An otherwise passionately argued article ready to share, but then the f-bombs start flying.
A serious question in return:

What's wrong with speculation and evading government interference?
Very informative, especially the second page, thanks for linking that!

If you have any other suggested reading re Xen / Virtualization I'd be very interested in them.
I dislike small countries, I felt claustrophobic back when Sweden wasn't a member of the EU and a move abroad would need to be planned many months in advance with reams of paperwork. Problems were smaller scale back when we had those itsy-bitsy countries that Stross is so romantic about. Small countries today only breeds parochialism (not in my backyard!) and cultural backwardness.

And EU isn't an escape valve from that. Multiply the number of countries in the EU by three and watch it grind to a halt.

I wouldn't mind a nordic union swallowing all the nordic states and move away from the romantic idea of a state for every nation.
When I was reading this I thought to myself "wait, didn't YC have exploding offers before"? Glad you dug this up. It was widely known back then that PG viewed it as a "intelligence test" if you didn't accept on the spot. If you didn't, he didn't want you. So I guess now the tide has turned.

That all said, I'm very much against exploding offers. The person offering the deal may have a reason to do so but you should resist the urge to rush to a decision.
I agree with the sentiment. There's a lot to consider and test in practice, though any of those scenarios don't sound like show-stoppers. After all, humans are also machines, and where a person can "know that they have a laser in their eyes", a machine can equally well realize that one of its sensors suddenly started reporting weird results that don't match the expectations and that don't seem to agree with other sensors onboard or with what other cars nearby are reporting.

We'll have to sort out a lot of those scenarios, many by means of "testing in production", but as long as self-driving cars can outperform humans on average, we'll be better off.
The case is much clearer outside of the US, where the drawbacks of centralized currencies are more visible. For example, Argentina's rate of inflation was 30% in January alone.
"No, seriously: 95% of the discussion in the referendum debates and on the street has been about short term issues that can be resolved one way or the other in the coming days and months (occasionally, months or single-digit years)."

Talk about handwaving-I'd say that the currency system and EU membership are very big issues that deserve essays in and of themselves. I get he's a libertarian who doesn't like the Westphalian system (though why is it that conservatives and libertarians are seemingly the only people who give a rats ass about 17th century politics) but the actual issues of Scottish independence are more of an afterthought.
So it's an API for ACH? That could be a bonus for merchants, giving them a standardized way of processing low-fee payments, but what's the appeal for consumers? Merchants pay the credit card fees because offering the credit card option ultimately results in more revenue than not offering the credit card option.

The adoption needs to happen more so on the consumer-side than the merchant-side. Merchants can offer the service, but that doesn't mean people will utilize in. I get 1.5% back on all my credit card purchases, so I'm incentivized to put as much of my spending on my credit card as I can. I also get additional consumer and fraud protections on my credit card that are either not as good or completely missing from doing ACH transfers on my bank account.

I think BitCoin needs far more appealing consumer use-cases than it currently has to really hit widespread adoptions.
so is this like an OSB/Rules Engine/Scripted layer to control apps? put all your functionality in a dynamically callable format and then a processor control what happens all the time.. basically an interpreter for everything?
Thank you very much, we were really excited to launch an updated version. May be we did it a bit too early :)
Not really -- all the article says is that a person claims to have identified the "real" Jack the Ripper, using what sounds like pretty persuasive evidence. But would that evidence convict him today, in Britain? Or would it only show that he had a contact with the victim? He was known to patronize prostitutes.
Thanks for the info. I never really considered running my own but that might be worth doing.
Somewhat related, I posted this here some time ago: https://news.ycombinator.com/item?id=7877328

I do use venti outside of Plan 9 too. The CAS model is very simple, and the data is very simple to manage. Unfortunately, it screaks a lot compared to Plan 9, but it works, and I have daily versioning for all my files.

/edit: quoting on this site sucks, I gave up.
It looks pretty solid. two things:

1) on the pricing page it states: "It means that you will be only able to access all the messages, files and links sent earlier than one month ago. Basically you will be able to access the data sent latest 30 days ago." - This needs cleaning up.

"It means that you will be able to access all the messages, files and links sent in the last 30 days." would read better. As it is written it sounds like I can access history 2 months ago but not 5 days ago.

2) Lose the По-русски unless they are in a Russian speaking part of the world. I hate to say it, but you will lose customers in the US. There is a certain amount of xenophobia here, as well as the nationalistic "american exceptionalism", and other media fed concerns about Russian hackers stealing identities etc..

Because a lot of us dream of a decentralized, digital world currency enabling frictionless global trade, and we are willing to sacrifice exposure to volatility to achieve that goal.

And a lot of us have very specific attitudes toward the role of government in peaceful, non-exploitative trade, and see Bitcoin as a possible solution to what we see as constant governmental overreach.

In short, we're idealists. We've been at the forefront of many revolutionary technologies (Internet, 3d printing, etc.).
Thank you for your suggestions. Especially about the privacy.
IMO, the federal government is much too strong in the US and consistently gaining strength, especially in the last eighty to ninety years. Why do you say it's a weak federal system? I can't think of anything a national government should (and shouldn't) do that it does not have the power to do.
Basically we are building a very open platform where you can invite anyone, for example one of use cases would be if you are organizing an event with lots of speakers and you need to collect their presentations and answer all their question regarding the timetable etc. Kind of like a shared folder+small Q&A, where all data is seemlessly organized so that you would know for sure which version of the presentation is the latest one for example.
This sounds like a semantic argument that Apple could easily reject.
All forms of energy extraction ultimately convert mass to energy. The coal we burn weighs imperceptibly more than the combustion products. That's really a red herring, though -- you must be able to harness an exothermic reaction to convert what you have into energy, and unifying QM and GR is unlikely to have any implications about reactions at energy densities we can usefully use.
"only several decades into the future" sounds like a conservative estimate for partially autonomous cars becoming mainstream.
I don't think he's a libertarian. See, for instance, his take on Bitcoin.
