Our StartUp Voucher,Solution to Paper Receipts the World Has Been Waiting For
My partner and I have recently started a cloud-based receipting platform startup called Voucher. Voucher is a smart receipt printer that seamlessly and wirelessly sends a digital receipt to the consumer's smartphone right at the checkout line for all transactions involving a credit/debit card. No more pockets, handbags, murses, or glovebox compartments filled with crumpled receipts. Voucher uses proprietary technology for which we have a patent pending, and is thus at the forefront of the Internet of Things (IoT) revolution.

With 82+ Billion credit/debit card transactions annually in just the US alone.Retailers in the US spend 3.4 Billion dollars a year on just the printer paper alone. Voucher has the potential to benefit both consumers and retailers, financially and environmentally.

We would really appreciate your comments, wisdom, advice, and support both publicly and financially as we attempt to realize our venture. Follow us on Twitter: @Voucher_Co for more informations and updates.

Honestly nobody should get married to someone with incompatible preferences regarding coffee ;-) This is also the beauty of the aeropress or paper cone method: you make your own coffee, everyone else can make theirs or not. And when I make the french press too strong, I'm happy to drink the whole thing myself!
Ask HN: What is the “hello world” or “to do list” of Bitcoin
I want to learn the basics of bitcoin. I am pretty limited in my skillset as a developer, but am really interested in this technology and am looking for a small project to get started on. I can code javascript and ruby, and know basic js frameworks(angular, jquery, handlebars, rails, etc.) I just want to learn so would be willing to take on learning more, and would be excited. Basic app ideas and resources would be super helpful.
How You Can Build an Incredible Founding Team
As the sinking of a boat and the accidental death of a crew member have little to do with the effectiveness of torture, I can only conclude that you wish to partake in a bout of gratuitous French bashing.

In this case, I suggest that you start by getting some better material. The Rainbow Warrior is just a blip on the radar. You will find better attack angles in our post-WWII colonial behaviour (for instance, the repression in Algeria and Madagascar), our colonial wars or our African policy. Godspeed.

Also if you look at the skin of older people from a sunny place compared to the skin of people from an overcast place, it's noticeably tougher and more wrinkled.

I'm an Australian who has lived the last ten years in the UK and my older Australian relatives definitely have older looking skin than my husband's UK-based family.

Plus the rate of skin cancer is definitely higher in Australia. It is a real public health issue there.
I have been using Vagrant daily, for little over a year and a half, to create fairly complex muli-node lab environments, and have not had similar experiences. The thought of going back to manually doing this again is not a pleasant one! I guess there are a couple places you could look: the OS images you are using (if they are flakey then the entire chain breaks), your machine (SSD makes things go quickly), your vagrant install (try upgrading), your virtualization software (try upgrading), etc. If there are real bugs, then file them on the Vagrant github page [1], and hopefully we can all benefit from the fixes.

The way I had it explained to me I always really liked. We spent a long time on very simple things: logic, control flow, functions, variables. Then, after learning that and all the limitations of those tools, my teacher said: "an object is something that can contain functions and data. In fact, in many languages, functions and variables are both objects."

At least that's how I remember it.
Why you should not go into academia
The relevant clauses in the DMCA read:

"No person shall circumvent a technological measure that effectively controls access to a work protected under this title."

"[..] is primarily designed or produced for the purpose of circumventing protection afforded by a technological measure that effectively protects a right of a copyright owner under this title in a work or a portion thereof"

Just about any software DRM exists to protect some kind of copyright. In this case, however, I don't think the Keurig authenticity check controls access to any copyrighted work (not even a trivial one like a logo or small program), so it wouldn't count.
My pet theory (with some anecdotal evidence) is that a lot of external investors are buying up most of the inventory. And a lot of young people making > 100k will spend large amounts of their income to live in the bay area even if they have to have roommates, etc. Cities like SF and NYC do have the advantage that you don't strictly NEED a car at least in some areas (and of course the gas, maintenance and insurance that goes with it) so that frees up a decent chunk of cash too.

What generally happens is once people start getting married and having kids they move to other states. I have seen this with several friends.

I can understand why the algorithm for some fractals can turn out to look like plants. What I don't understand (probably for lack of reading up on the subject) is why do plants look like fractals. I mean you won't find some microprocessor in every plant issuing orders to grow according to a fractal formula so I assume this is a emergent statistical phenomena from constraints within the plant genetics - but is the bridge between the fractal shapes and plant shapes well understood?

Ask HN: Where should I look for high quality laptops in a post-Thinkpad era?
I've been a huge Thinkpad supporter up until recent years. The general consensus is that Thinkpads aren't what they once were. The final straw for me was the touchpad F-keys on a more recent Thinkpad. Where should I look for laptops with similar industrial design qualities?

The sandbox at the end has a slider to change the ratio so you can tune it to simulate race instead of gender (although having more than two shapes would be nice, and also other dimensions than shapes to observe intersectional interactions).

I would suggest you start with reading "Signal Processing and Linear Systems" by Lathi (great book, had it on a course) so that you gain some understanding on signal processing.

After understanding filters, and frequency analysis, you will be able to ask more specific questions than "how to isolate a voice from a single sample?". I am just finishing a course on Image Processing and while some of the stuff that I learned on Signal Processing was useful, I would describe it as being only primitives (think of as integers, doubles, and control structures in programming languages) and we explore higher level of abstractions (segmentation and classification techniques). I assume the same is true for audio signals, and recommend as well to read a specialized book on the subject. I am sorry I cannot recommend one.
I did not know what, I tought you had to build a new release (from which you could distribute deltas), for the simple reason that no Android device does that.

It's not a viable method for updating generic servers however. An update system needs to do a lot more than just swap out a file. You need to know about dependencies, restart services etc. It's also important for real world usage to be able to skip one update for one reason or another.

It could be interesting for single purpose Docker containers which can be restarted at will.
Why?

The Arist makes espresso drinks and will cost at least $400 whereas the Keurig costs less than $150 and makes drip coffee.

The Arist looks great, but there is probably very little crossover between the two sets of customers.

Actually in the case of Xlib and Xt it was even worse.

Motif made it better, but still.

My exercise for fellow developers joking about the Windows API was to ask them how they would do similarly in Xlib/Xt/Motif.
There's no way they'll be able to fit so many features at in a $300 product.

There's already a pretty competitive bean-to-cup coffee machine market, and $300 price point usually gets you a machine that grinds, brews, dispenses and sometimes froths - very poorly, and requires maintenance.

Heck, even a good, “real” espresso machine and grinder (like a Rancilio Silvia and Bartza Vario, entry level coffee geek favourites) combo will set you back around $1k.

It's a pipe dream.

In the last 8 years the pirate bay hasn't changed? It went open source and embraced magnet links entirely. Making it so that almost nothing was being hosted on the server itself. You can download the entire pirate bay in 90MB to put one up of your own. There are hundreds of pirate bays all over the world running on almost nothing allowing everyone to download the same things at the same speeds.

[edit: It didn't go open source.]

To suggest the pirate bay hasn't done anything is just lame. Not as lame as sending 20 something's to jail over it but getting there.

The ads were because of legal defence fees, which can be huge.

Unfortunately, most of the things that need to be written in C need to be written by someone deeply experienced with C, which would not likely be an optimal fit for a new grad. Fewer things are being written in C when they don't need to - about which I have mixed feelings but which is also probably the right thing.

To get to "deeply experienced with C" in that environment, you're likely talking about personal projects, and/or working on existing code that doesn't really need to be C any longer but is because porting the whole thing is more work than worthwhile.

The root of the problem is that the state is a monopoly on violence. What is a "citizen" supposed to do? Vote for the red master or the blue master next time? It makes no difference.

The best thing a "citizen" can do is recognize the state is foundationally unethical and has no legitimate political authority and never did. [1] Once we leave behind the mysticism of state authority, perhaps we can find better ways to organize society in ways that are ethically sound.

Many namespace/module systems let you do something like

import really_long_name as rln

You still get the answer to your question, without sacrificing terseness. For the record, I also tend to use fully-qualified names when it makes sense. Some languages make this impossible though (I'm looking at you, Java and your files with twenty or thirty lines of IDE-generated imports).

Having never heard about the controversy, I was quite shocked to learn exactly what Watson said in 2007:

In 2007, the Sunday Times ran an interview with Dr Watson in which he
said he was “inherently gloomy about the prospect of Africa” because
“all our social policies are based on the fact that their intelligence is the
same as ours – whereas all the testing says not really”.

He told the newspaper people wanted to believe that everyone was born
with equal intelligence but that those “who have to deal with black
employees find this not true”.

Source: http://www.telegraph.co.uk/news/science/11261872/James-Watso...

It's painful to see scientists fall prey to overgeneralization from small, non-representative samples - especially when their words have influence. I'm glad Usmanov returned the medal - Watson certainly earned it for his earlier accomplishments - but I'm not surprised Watson's unable to find jobs.
There are a few options I suppose.

If you would like to consider an alternative, I run a site called Postatic (http://postatic.com).

It's a site that let you create online communities (think of it as 'creating your own hackernews'

But you can also make it 'private' so that only invited and approved people can access the site, which makes it ideal for your situation. It might not be 100% perfect for your purpose but would love to have you check it out if you have some time. Happy to answer any questions!
Did you use the Nespresso cleaning kit and then run the entire water tank through the machine twice without capsules?

I have many Nespresso machines and never had a problem with degrading taste. Usually something else breaks like the milk frother on the Lattissima.
The fact that it's hosting torrents in flat files or in database rows seems like a minor technical difference to me. Apart from that, the same broken UI doesn't seem to have changed much in the past 8 years. I didn't know that TPB was open source... surprised that the community didn't try to improve the UX a bit.
And if you have a need for it to be precisely correct, I have bad news for you about the word "random".

Many, many more providers are along the way. The providers already exist in the open source so its just a matter of enabling them one at a time in Atlas. But we have some surprises planned for some of them as well. :)

You probably wouldn't have got in much trouble, just a c&d and probably asked to fork over some money from your profits and sign a contract with google that youll never do it again (And "your" account on google disabled"). ;)

At least thats what happend with me and my friend when we mined about 1/10th of users from facebook, and crowdsourced a bunch of info from people, made it public, (we had an psudeoanonmyous no login messaging feature where people would literally share informaion that would make people question what privacy is when n-1 people are divulging everything about you) from searching names. If I wasn't a US citizen, id probably do it better now that i know more of what im up against. Maybe the landscape might be more open in the US in the future.

People moan on and on about facebook and companies like them as if they are all powerfull (they can seem that way if you play by their rules and submit to their jurisdiction for pragmatic reasons), but challenging those assumptions and leveraging user behaviors, and arbitraging legalities, one can probably crack some pretty big holes...

Natural selection only molds us up to the point where we procreate and ensure the survival of our offspring. After that (say age 50), we're winging it.

Mild stressors that would occur naturally - physical exertion, exposure, hunger; it is perfectly logical that natural selection would favour those who handle these circumstances well.
Enable Debugging Mode and Unhide Developer Options on Android 5.0 Lollipop
Macbooks are great in their own right but they don't (in my opinion) fill the gap left by earlier Thinkpad laptops, for several reasons: Lack of removable battery, fewer options (msata, main sata, secondary sata, 3g etc), VGA for presentations, trackpoint, ease of access to internals, value for money, etc.

I have looked into HP Elitebooks but I have been burned by HP and seen so many others burned by HP that I hesitate to invest in them.

Sorry about that, had to finish up quickly. I will try to clarify my view, and sorry again if this wall of text is too long. I just wanted to stress that Consistency is about data itself, while Isolation is about dataset acquisition (the same goes for Atomicity).

My view is that Consistency should only be mentioned when talking about data. It is much like method argument type checking in type-safe languages: if you get float passed in it WILL contain a valid number and you do not need any additional explicit checking for that. Consistency is data validation.

Isolation, on the other hand, is a form of concurrency control. Once you have shared data between concurrent threads, care must be taken. SQL brings this to a new level by having only shared data between threads (transactions). Since performance is directly related to concurrency control techniques, some compromise must be taken. The article is just about those compromises. Phantom reads can be viewed as a manifestation of holding and releasing locks (semaphores) during thread execution.

I believe that ACID properties are all orthogonal and databases should be examined where/when/how those properties are violated, e.g. Isolation is not always ensured because of the mentioned MVCC.

Atomicity: data is treated in atomic datasets;
Consistency: data validation;
Isolation: data immutability during transaction;
Durability: data retention (and as a consequence Consistency) over prolonged periods of time.

But that is my own humble opinion.

Why banning cab services in Delhi is completely justified
Actually, there is a difference between hosting the files and just linking to them, and is by no means a "minor technical difference". Although to be fair I think it was done not only to increase portability but also to decrease legal targeting, the latter of which seems like it didn't pan out in the end though may have thwarted some legal efforts along the way.
