A camera taking lurching steps through the Marseilles nightlife? Meh, it's been done. ;) https://www.youtube.com/watch?v=vuOecH5NoXs
Looks like there is also a mobile app.

I bet they built custom hardware for a couple reasons:
1. Custom hardware sitting around reminds you of Amazon and your ability to order. Having a new device feels more futuristic, which does seem logically odd.
2. Durability. While cooking etc, you dont' want to touch your phone. This looks very easy to clean/throw around.
3. Barcode scanner speed. Apps with cameras are much, much slower at recognizing barcodes than this. This removes a lot of interface. Just scan it and you're done -- no hassle switching apps, holding the camera just right, etc. I bet this feels more natural.
I imagine every single product you order from AmazonFresh would have one. This would really be for re-orders.
This product keeps your personal Amazon shopping account out of the hands of the rest of your family. With Dash, it seems, your 7 year old can add items to your shopping list without being able to Checkout... or, your wife can add items to your weekly grocery list without seeing what you've got in your shopping cart for your upcoming anniversary.

It gives everyone "Add" ability without having to log them into an Amazon account on everyone's smartphone.

Though... I guess this could be solved with a token... but in general the more I think about it, the more it seems to be considered in terms of keeping your family connected without them being "too" connected.

Just a guess, though. Playing devil's advocate here. :)

Where are OKCupid's protests against Intel? 538 didn't release names, but surely they can't be hard to find, and if there is reason to burn one heretic then by induction there's reason to burn all the rest. So what is OKCupid waiting for?

That's a great approach - specifically reassuring the user that you're not going to do anything malicious with their contacts. 95% of the time, if an app requests access to my contacts, I will deny it fearing that it's going to spam them text messages like "Dav- is using ShittyFooBarApp – Click here to join them! http://spammy.co/ad9s8hu".
Genius. I've always wondered how many people actually take the time to scan QR codes on posters and such. I mean, don't companies track QR code scan-through rates?
If its real, this is going to revolutionize grocery shopping. Also, open up a new market for such devices.
Just because they believe that Homosexuality is wrong doesn't mean that they are opposed to people who are gay.

Some of the text looks terrible on my Windows 7 - Chrome environment. Especially everything in How It Works.

The website is all about the sell side, and you say the buy side is ebay, craigslist, autotrader, etc. Why not post the cars in a store on your site too? Last time I checked those sites, they had a terrible UI.

In fact, that idea expands the business from a seller's assistant kind of thing to more of an online-focused CarMax. I think that could be really useful to everyone. I'm thinking kind of a cross between AutoTrader and CarMax. On the buyer's side, it could be like the existing online sites, except that the photos and details are collected by your people, so they're consistent and high-quality. Maybe you take the car for a few hours, have a mechanic check it out, wash it, and take high-quality high-res photos in a controlled environment. The buyers can know and trust that you've done all this, and that they're getting a good representation of what they're thinking of buying.

The sellers get pretty much what you're already doing, all of the legwork done for them, a better price, and hopefully buyers who know what they're getting, and are vetted as serious buyers before a test-drive is set up.

I suppose the main difference between you and Carmax, then, is that you are all online, thus have a much better online presence, and don't need to maintain a car lot. Does that translate into enough of a cost savings to offer a better deal to the customers than the current incumbents, though?
I've been trying to come up with a use for Cramhole.com for twelve years now.

Still no luck.

For a while, I was hoping to use it for a data storage algorithm, protocol, wrapper or container of some sort. Just so that in the future some poor souls would be sitting around a conference table and somebody would chime in "Couldn't we use a Cramhole for this?"
yeah possibly that too.

Found this: "Proposition 8, which banned same-sex marriage in California, passed with more than 52% of the vote statewide. In the four most populous Silicon Valley area counties, it received just under 38% of the vote. The measure was later overturned by the courts."
Exactly. This is a play for the next tier of developers, which will mostly be enterprise, mostly use Windows, and be much larger.
Legalizing drugs isn't about oppressing a minority. Outlawing Interracial marriage would be a better analogy. The same arguments are being used which cite religious beliefs ( http://en.wikipedia.org/wiki/Miscegenation ) .

HN'ers asking why this isn't a cell phone app take note - this exemplifies why we (geeks) don't make good use cases for consumer tech and we should always be careful looking to our own habits and values when in a Product Development role.

We're rarely the target customer and rarely behave like "average Joe". We're naturally resistant to superfluous redundancy ("My phone can already snap a barcode, I don't need a separate device") when consumers don't even see the duplication let alone the issue. They don't separate devices (or even apps) has having layers of similarity and just see things for their end functionality.

My mother would see a phone and apps as completely separate functionality to a physical device like this. She probably would have the Amazon Fresh scanner, the (theoretical) Google Shopping Express scanner and the (also theoretical) Whole Foods scanner and wouldn't even consider the duplication, let alone be frustrated by it. She doesn't care about the potential for an "open standard"/"common standard".

She also has an AppleTV and a ChromeCast connected to the same smart-TV that also has native apps within it (she mostly uses the native apps). Again, she sees no issue with that and might even buy an Amazon FireTV if she felt it was more compelling for one use.

Ultimately we shouldn't assume consumers value convergence, especially when it creates ever increasing complexity in user experience (eg opening an app to snap a barcode vs pressing a single button on an Amazon Fresh scanner)

ADDED: If you don't have parents that also work in tech, go visit them and just watch them use technology without prompting. Ask them about their experiences, their frustrations, their decisions behind purchasing specific equipment and downloading particular apps. It's very insightful.

The $299 annual fee does give some sticker shock, but annualized that's only about $6 per week (more like $4-5 if you already have a regular Prime membership and deduct that existing cost). Especially if you're shopping for 2 or more, that comes out to a pretty small tax on your regular grocery bill.
most people keep their phone on them most of the day, especially those willing to grocery shop online. i don't feel like finding a phone and pressing maybe, 3 buttons, is any slower than finding some other gadget tucked in a drawer somewhere in your house, and pressing one button. i don't see the point of the hardware here, even though finding an app on my phone is apparently 4 steps.

I hate selling cars. It's troublesome and time consuming, so you I'd gladly pay for the service. The pricing turns me off though. Selling a 50K car, the commission would turn out to 2.5K. That's net. So with 50% income tax rate, I'd have to earn 5K to pay the commission.

That's much too steep for me. If there was a cap of say 1K, I'd be a customer in a heartbeat. But 5K gross is certainly worth the inconvenience of selling it myself.
Once upon a time I would have. But these days, I'm just sticking with the stock firmware. I haven't even rooted it! (gasp) I can live without the Facebook app.

The champion of the theory attributes the lack of genomic similarity to repeated back-crossing to one of the parent populations. To put it in other words, the droplet of initial hybridization got diluted in the larger gene pool, but the novel genes (and thus traits) remained and underwent selection.

That being said, diluted gene contribution is not the same thing as no gene contribution. To even begin accepting such a theory I would require direct genetic evidence showing considerable horizontal gene transfer between porcine and hominid lines.

Back in the early 2000's, I was planning a trip through the mid-east and trying to get my visas sorted out.

That's when I discovered that syrianembassy.com was available.

I had nine dollars in my pocket at the time, but somehow it seemed like something that would eventually cause me more than nine dollars worth of hassle, were I to pick it up and put something inappropriate there.

Looking now, it seems that somebody is squatting it. Still, I'm glad that somebody is not me.

I used to work a part time job at a sandwich place to do something different every day, talk to people, joke with co-workers, and learn new things. All while being a software engineer (consultant). Taught me a lot of things and it was great just doing a job that only required me to put vegetables on a loaf of bread.
This may be a little early to consider but there are several websites that will allow you to get a PCB printed (multilayered and silk screened) at small sizes and in small runs (~3 copies) economically by filling a larger order with a number of boards and cutting the board into the component orders. Generally you will upload your Eagle files or whatever and then watch a progress meter for the next board fill up over a week or so until it is ordered and shipped. Great way to save cash when prototyping. I am on mobile currently but I will link to an example when I get home.
You can wait an extra second and maybe get it filled.

Or maybe the price will move away from you and you'll never get filled (at least at the price you want).
> I see absolutely no reason why this couldn't have been a mobile app with a bar code scanner and voice recognition...

They have that: https://play.google.com/store/apps/details?id=com.amazon.pri...

Barcode scanner, and voice recognition. It's not nearly as cool or convenient as a dedicated device though.
The conclusion section goes onto to link this to lower-quality of life as well. Still a bit skeptical of the findings... I always see articles regarding this with very differing opinions. Relevant article: http://www.plosone.org/article/fetchObject.action?uri=info:d...
I assume the use case here is you're in the process of using up an item. The easier and faster Amazon can make it to order a new one, the more likely they are to get your business. If I'm cooking and I run out of flour, I'm not going to stop cooking, pull out my phone, unlock it, swipe over to the screen that has the Amazon app on it, tap that, wait for it to launch, click the button for Fresh, and then finally type (or speak). I'm just going to make a mental note and buy it later from Safeway.

But with Dash, it's just grab the Dash from whatever convenient location you keep it, speak into the Dash, and put it back. That's easy enough that I would do it, and Amazon would get my purchase.

Unfortunately, Amazon Fresh really kind of sucks (at least in SF), so the whole premise is flawed. Oh well.
Best idea ever, wow what a great product and functionality! This should be in every house! :-)

Amazon acts like a startup still. Good for them!
This comment is perfect, in that it simultaneously gets my goat and pulls the wool over my eyes.
He didn't say front running has always been there. He said market making has always been there. Market making is a valuable service and it's great that it's cheaper than ever.
Thanks for that.

But still it was not any kind of market or trading risk that blew them up--just a litany of control failures and bad code.

This is a cool service to integrate with AmazonFresh. A similar promising alternative is https://www.rosieapp.com ... It's a pretty cool startup with similar goals.

Opening an app is, thankfully, something the tech industry has managed to train the average consumer to do.

I'd argue though remembering where you put this thing, or "oh hey the wifi password got changed why isn't the food scanner working?" adds lots more complexity than hitting an app icon. The app route also enables you to have multiple scanners - since the target audience of such a product is probably already heavy on tech, and most probably have multiple cell phones.

I guess that last line might be the issue. It isn't really a cell phone, it is a capacitive touch computer with a microphone and speaker, but that is something we haven't yet conveyed well.

Source: http://en.wikipedia.org/wiki/Right_to_housing

[snip]

Article 25 of the Universal Declaration of Human Rights recognises the right to housing as part of the right to an adequate standard of living. It states that:

Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.

[/snip]

Doesn't sound like the right to an adequate standard of living (which would include food and shelter) is a negative right to me.
Only by implication. Calling someone a shill could be considered "only" an attack on credibility, but it's also an implied argument that the speaker lacks the right to speak on that subject.
Unless you go by recent popular usage, in which case every possible interaction with anything that is not specifically laid out in that thing's accompanying instruction manual is now considered "hacking." Case in point: Life has no instructions, so people happily call almost anything "life hacking."
I am not referring to Knight.

[Edit] I am referring to another firm; it seems if you are in the trading business, you are taking risk. This certainly has multiple meanings. You can measure risk against a position you hold relative to holding nothing. If you are a Market Maker HFT, then you risk the market collapsing out from under you when you are legally obligated to stay in.

Basically, no.

While goats and sheep diverged 8 million years ago, humans/chimps and pigs diverged 80 million years ago. The last time a proto-chimp got with a proto-pig, the T-Rex hadn't evolved yet. While goats and sheep have a difference of 6 chromosomes, chimps and pigs have a difference of 10. McCarthy, despite being a geneticist, makes his absurd claim without even discussing the genetic difficulties.

What little similarity there is between humans and pigs is simply a case of convergent evolution.
Thing is that we don't use a traditional christian framework. We throw out most of the old testament and much of the focus is on the new Gospel. Explicit line against gays lies in Leviticus, and like most of Leviticus should be ignored.
Yes, one of the things people do is arbitrage price differences between exchanges. That's great though! The fact that people are constantly doing this means that I can trade on any given exchange and be really confident that I'm getting the best price.

> You're going to have to learn to read AT&T syntax assembler anyway when looking at disassembly in the debugger

Not anymore. I use `set disassembly-flavor intel` in my .gdbinit. Modern LLVM binutils clones also allow disassembly into Intel syntax with `-x86-asm-syntax=intel`.

Modern versions of GAS can also use the `.intel_syntax` directive, which carries over into GCC inline assembly.
Actually I think it is simpler than that, there was a time when the programmability of the phone was so much better than you could do in a cost effective embedded system that it was the right choice. Now you can put a 32 bit ARM Cortex M on a device for $3 and so spending on the plastic is more feasible.
I agree with other critiques here that this A/B testing calculator does little to add to the conversation, and someone who uses it would be mislead in how to interpret results.

The procedure my team uses is:

1) hypothesize an expected conversion rate and whether to use a one-sided test (if we're testing that the state of the world remains unchanged) or a two-sided test (if we're testing that that the state of the world has changed as a result of the variation)

2) run those numbers through this power/sample size calculator to determine the number of visitors we need before we can analyze the experiment: http://www.stat.ubc.ca/~rollin/stats/ssize/b2.html

3) wait for traffic

4) after enough visitors have come to the funnel, pass the resulting conversion numbers through ABBA http://www.thumbtack.com/labs/abba/ [1] to see confidence intervals on our results

To add to what jeremyaarts said, last year Lego released an upgraded version of their Mindstorms set called EV3. I know there was a board that allowed you to enhance the older NXT Mindstorms set with an Arduino, though I'm not sure if this board is compatible with the EV3. One of the nice things about the EV3 is that it runs it's own version of linux, however you can also can run a custom version of linux on the EV3 if you want, opening the system up to a world of fun :-)

Yeah I love how dirt simple SSE is. WebSockets tend to be the go-to choice for realtime push, but many applications don't really need a bidirectional socket. SSE for server->client and XHR for client->server interactions is good enough for typical REST apps.

Also, (plug alert) SSE is pretty easy to throw together using https://fanout.io/ and its HTTP streaming data transport, if you want to save yourself from having to set up any new server stuff.
