There are a few examples of purchasing:

1. Heading to a grocery store with a list of items that you frequently buy that are priced at similar prices at every store.

2. Going to a store to purchase a specific item

3. Going to a store to find an item

For case #1 it's most likely that you're shopping at a place that is already competing for the lowest price point (places like Walmart and Target) so this application would be useless to you; however these stores already engage in the sort of activity the OP discusses.

For case #2 if it's an item you've purchased previously you probably have a "favourite" store, one that you used previously and had a good experience with so naturally you go to this store. If this is an independent store they might have the item for $5 more than another store of a similar type, but because you've used this store before and because it has always been cheaper on previous occasions you bet that extra $5 against the time investment of finding if it is cheaper elsewhere (which isn't guaranteed) and go with the "safe" option.

If in case #2 you didn't have to consider your previous purchases, if you could just type in the product into your phone and be told (without doubt) that the product is $10 cheaper at a store across the street from your normal store most people would take that; it's $10 that would be saved by walking across the street, it would be stupid not to, right?

So now you have a situation where in case #2 any store that stocks an item (HP Printer, for example) is required to stock it at the lowest price because if they don't and a competitor is within 2 blocks (the "distance of $10") people will just go there instead. So now where is the value to the retailer? They enable themselves to be pitted against their competitors, thus requiring they lower their margins and inevitably lose out to bigger stores that can work with lower margins.

In example #3 the same situation occurs, you enter a store and locate the item that you want, enter it into your phone and get told exactly where it can be acquired and at what price; if the store that has it cheapest is 2 blocks away and the price difference is $15 why not go over to the other store and save the $15? That store just lost a sale because of the system.

Almost everyone that I know (I'm not from a rich background) would absolutely walk over the street to save $15, that's a non-neglible amount of money to quite a large portion of consumers. Sure if every other store has the item cheaper but it's only $0.25 difference people probably aren't going to go to another store, but then it becomes a race to the bottom. Wonderful for the consumers, awful for the retailer.

What incentive is there for a retailer to force themselves to reduce their own margins? Currently purchasing an item in a retail store is a gamble on whether or not you'll pay the lowest price (unless you spend time researching every stores pricing), stores make money because of this. Currently it's a matter of taking a consumer, showing them a product and convincing them to purchase, if this system existed it would have an extra step: convince them to purchase at that particular store.

I scan a QR code at my local coffee shop almost every (week) day. I use an app that acts like an electronic loyalty card - you scan a QR code when you get a coffee, and every 10th coffee is free (and I find I'm actually more likely to do it, unlike with cardboard loyalty cards where it feels like you're inconveniencing someone when they're busy by making them mark it).
We do use mmap, but we do not use memory mapped files. We use mmap to allocate big chunks of memory from the OS, which we later distribute to our custom memory allocators.

It's not a column store. We are thinking about it, maybe some time in the future as we add more analytical feature. It's a row store.

We do write back to dist. We have a transaction log, which we truncate once it grows over a certain threshold, by taking a snapshot.

> Unix time is completely ignorant about anything except seconds

That's not correct, actually: UNIX time tracks UTC instead of TAI meaning it "corrects" for leap seconds. As a result, UNIX time is not "the number of seconds since epoch" but "86400 * (number of whole days since epoch) + (number of seconds since midnight)", and UNIX time will go forwards (never so far) and backwards on leap seconds (a second will repeat in most implementations as the day goes from 23:59:60 to 00:00:00, as they have the same timestamp).

It's probably not the whole truth, but i suspect Sequoia is doomed to spend its operational lifespan simulating the effects of radiation on 70's era electronics. It's not bad... just kinda sad.
Sure, I can do some IOCCC entries.

* This entry is an entire flight simulator/3d demo/fractal generator/graphical chess program in like a quarter of a page! Wow!

There, I've already covered most of the entries in a very easy explanation. Oh, and a lot of them put the source code into a cutesy shape or substitute out normal "C" words to confuse the reader. It's easy to point out features like that too.

* The C language lets you list word replacements to apply to your program before turning it into machine code. For example you can turn every "NEXT" into "start_printer(); feed_page(); shutdown_printer();". It's a great timesaver. You can also use it to say 'dump this entire file here' and centralize code that's used a lot. This entry has hundreds of replacements and does that entire-file-inclusion over and over. It uses tricky methods with all this replacement to pre-calculate the answer to a math problem before it's even turned into machine code. So the actual machine code ends up doing zero computation before outputting the answer.

* This program was being cute. Normally it's tricky to write a program that prints its own source code, because it's like making a sentence that contains itself. But turns out that some compilers will turn a blank file into machine code that does nothing. And doing nothing means you get a blank file for output. They changed the rules after that.

The last example is like a good example about modern art. It makes a point and pokes fun at the rules but you can only make so many clever observations about any particular thing. Almost every winning IOCCC entry has a legitimate purpose. And you can explain the purpose. Even though explaining the joke will never be as funny as natively understanding it. In art, explaining the purpose (even if it's something simplistic like capturing a scene) can expose those pieces of 'art' that have nothing to them (like the ones made by people with too much superglue and a desire to be 'shocking').

Also upgrade complete lays bare its jokey demeanor in the first couple seconds of menu, before you even reach any references or old-school graphics. You may not fully 'appreciate' the game but you can certainly understand and enjoy it without being a gamer.
Yeah. I guess it was OK. It doesn't hurt to see other invoices. I shoot a E-Mail to Heroku as soon I saw your post. And a couple hours later it was fixed. But if you find next time a more serious security issue, like credit cards or SSN infos or something like that, please don't push it to HN. Contact immediately the provider. It is a human thing to make mistakes and security issues are one of this mistakes.
That would be the ideal interface.

1) Open camera from lock screen
2) Take photo
3) If QR code is detected, offer to open it.
4) Later when browsing photos, remember it's a QR code, offer the link again, so that we can come back to it later.
5) If no QR code is detected, treat it as a normal photo.

Not without signing your boot image, AFAIK. Microsoft had a program for allowing companies to sign UEFI boot images, but I'm not sure that will extend to ARM machines.
I'm not sure what you're talking about, there doesn't seem to be anything about taxes in the OP. You sure you have the right thread? Can you explain more?

One of the things that separate us from Xeround is the fact that you can see the benefit of super high throughput on any linux box, including your laptop. You can download the software and use it by yourself.

Shit website, shit marketing, and shit video aside, I'm seriously intrigued.

Microsoft has five cards to play here:

- REAL Windows (TM) and Massive Microsoft Developer Mindshare
- Ports, ports, ports!
- REAL Microsoft Office (TM) INCLUDED FREE on the low-end model
- PEN AND KEYBOARD!
- Billions of dollars in cash to burn making this happen

And they have three huge challenges in front of them:

- Windows 8 critical reception
- Their ability to execute
- They will be shipping these, at best, about two months before iPad 4 ships

Execution is going to be everything. Make this a work-friendly wonderbox that effortlessly supports Exchange, remote management, SharePoint, SkyDrive, SMB, OneNote, and Communicator/Lync? The iPad will blow off conference tables like crepe paper.

Make a fussy little piece of shit that takes the same amount of work to set up as a laptop or otherwise scares off IT? Doom.
> I know what I want my user interface to look like. I know what fonts, colours and relative sizes I want things to be.

Designing an user interface is mostly not about picking your favorite font and color. It sounds like you use the word "design" for what is actually "theming" or "skinning".

H1-B visas - exempt to non-exempt transition?
I am working with a university on a cap exempt H1-B visa. Recently I got a job offer from a profit-making company for which I need a non-exempt H1-B visa (subject to an annual cap). As my current visa falls outside of the cap, I am told that my new H1-B will be subject to the cap. The cap for FY-2013 was reached last week and hence new visa applications are not being accepted now. So even though I have a job offer, it's not going to work out.

Now I have to wait until April 2013 to get a new H1-B visa for the job starting in October 2013 (FY-2014). It doesn't seem practical that any employer will wait for 6-months for a potential employee to join the company.

Are there any options available to me so that I can work for a profit-making company? Am I missing any points here? I appreciate all the help.

No, it won't. NFC is (and will be) more expensive than just printing a label. It also gives no benefit to the user compared to scanning a code. User has to take the phone, and get it close to the reader, just as with NFC.
Dating a girl who is using me for market research
TL;DR met a girl on okcupid who might be doing market research on me for a competitor. what should i do?

i'm a terrible story teller, so hopefully i don't bore you guys too badly... i recently started using okcupid and got matched with a cute girl (yay). i see that she replies often which is kinda weird because it seems like the cute girls only reply selectively. i don't think much of it and send her a note, and she replies back saying she'd be down for dinner or a movie (more yay). when II try to set up a date though she pushes back (boo). and every time since then for the past 3+ weeks it's been more of the same. more boo.

for the past couple days, i was bummed and just took it that she lost interest. after some pressuring from a friend, i decided to look her up on facebook today. she gave me her email address so i know her last name. it turns out she and i actually know some of the same people! i'm going through her profile, and i find that she does marketing for a dating startup NOT named okcupid. my friend who is a marketer goes all conspiracy theory and gets me thinking that she is actually doing market research. at first it sounded weird but...

what do you think? am I just a use case? usually when girls say they will go out with you they make time right? pushback means you are lower priority, no?

she said to try her again this week but i had been reluctant to because i didn’t want to be strung along anymore. now there is this twist to the story. if anyone out there has any suggestions, please don’t hold back. i’ll update this post with what happens. what should i do???
The defacto-standard already seems to be happening with Twitter Bootstrap. Give it another few years and I expect this will spread into more well-known apps (or the current startups using it will become more prominent).

And I do think people are addressing the other issues. Chrome's Web-App API can open pages in new windows without the browser UI, and Firefox is due to have their similar API available soon.

Things like keyboard shortcuts will likely sort themselves out eventually: for example, Github's issue tracking tries to mirror the keyboard shortcuts of gmail wherever the actions are similar.
Apologies. It doesn't sound right indeed. What I meant is that it takes a certain mindset to appreciate art.

Not sure what you mean by "ordinary" language though. If you want to express hunger in a way that is not indifferent, how would you say it?

Emin's famous "unmade bed" is actually very ordinary. But when you see it in the exhibition (not a photo), it says something interesting (to me) about privacy and modern life, that even a long essay cannot express.

In contrast, a "retina" ipad icon may look extraordinary, but it doesn't tell me anything interesting.

To me, that's the difference between art and design. Just a thought.
Deep Tissue Massage
Deep tissue massage is a massage type for those with chronic pain and muscle tension. Often times this technique is used for those suffering from sports injuries, whiplash or car accident injuries. The massage therapist uses slower strokes or friction techniques across the muscle fibers. Deep tissue massage is used for chronically tight or painful muscles, overuse syndrome, postural problems such as forward head posture, or recovery from acute and chronic injuries.

Why giving the software for free? Do you have any idea how complex is managing retail inventories doing proper cost analysis and stuff? There are companies doing only that. What makes you think that you will be able to do than and sell it for free?

The real thing here is that finally, even if only in part, a software for business use has come to the HN first page. It would be cool to focus on that for once...
> they don't waste a lot of time making sure their inventory is extremely accurate.

Correct me if I'm wrong, but isn't this one of the reasons why Wal-Mart became so successful? They could track their inventory very accurately.
I think you should think twice before taking this step. I love programming, but sometimes I feel the same. Sometimes I think maybe I've chosen wrong career and I should really become a taxi driver. But it's all from sameness. Try to change not your career for now but, for example, the project you are working on, or try another programming language (this helps me a lot). At last try to create your own project, even small, but it'll bring you joy back!

...except that there were countries that weren't using the Gregorian calendar until well into the 20th Century, so you can't even reliably deal with dates as recent as the mid-1900s across borders under that assumption.

But don't worry, they're just small countries.

And China.
I was really shocked when I found out, that Unity is not running under Linux. They are flooding the Monologue (Mono) news feed - but their product is not running under linux. Couldn't quite understand this.
This is so misguided. Just make the hardware(all features incl suspend, backlight etc) work with the LTS + latest version of Ubuntu and we would all be happy. And don't restrict it to one under powered model, with a shitty screen.
There is no disappearing division between devices, there is rather a stronger division between mobile platforms (including tablet and phone) and PC platforms. And that division is only going to get stronger.

Maemo and Meego are dead. Chromebooks are not likely to blow up. If small ARM machines get popular it will be by running some weird mobile-type OS. Native apps seem to be much more commercially attractive than pure HTML5 apps. On the other hand, I don't see evidence that iOS and Android are going to become plausible PC platforms. Netbook sales have slowed way down. All the buzz is about expensive mobile devices like tablets, and expensive laptops, and these two categories are not converging. It only appears that a convergence is coming because mobile platforms are cannibalizing the casual uses for PCs and netbooks.

If they were doing fashion, they would change to a new look every year. Remember the disappointment when the iPhone 4S kept the iPhone 4 design? Apple doesn't care about fashion, they care about good design.
The problem is that you never know how long Microsoft will stand behind any of their hardware products.
They held firm with Xbox, they surrendered with everything else.
Last year, they canned their tablet plans. This year, they come back with a new tablet plan.
Etc.

Hysterical or desperate? I do not know.
My thoughts exactly. Every piece of software on the 8-bits and prior had a drastically different feel, even given the technical constraints.

But in the wake of MacOS and Windows 3.1, "native look" suddenly became a highly-touted feature. I think now that this was a result of low experience with desktop apps leading managers to "fake it till they made it" - presumably the OS makers invested more time in UX than the average app developer, so aping look+feel would get them a little closer to a "good" app.

Many have, take the sort of mathematics done in order to understand physics. Logic is the study of formal reasoning. Mathematics is the study of form and structure. It took R&W's Principia Mathematica to attempt to show that the entirety of mathematics was rested on a logical foundation. That's pretty recent on the scene if you think about the history of mathematics! To me, the idea you expressed, seems like a very 20th century thing.

The distinction still exists in theory it's just that "business mobile phone" started to seriously lag behind "consumer mobile phone". But Apple is not setup for (nor do they seem to care about) the business market.

The business market seems like it would be a huge opportunity for Microsoft to bring Apple-like technology to the business side. However, they seem far more interested in chasing Apple and Google in the consumer market.
I assume someone uses QR codes, but I don't know who, and I don't see why they are popping up in so many places.
