One can easily detect it by the phosphate spillage south of it.

As a teenager I worked at the end of a delivery conveyor belt for a supermarket. This was an unusual setup for a supermarket (but maybe for industrial or factory settings it's nothing special). The supermarket is located over a major highway. It's the Star Market over the Mass Pike/I90 outside of Boston (1). Customers had to take an escalator to the second floor, and after shopping and paying, 2-3 paper grocery bags were loaded into a small numbered cart. The customers were given plastic cards with the corresponding numbers.

The carts were swung onto the top level of a double-decker conveyer belt. It went down to the first floor (street level) and into a long, basement like room with a conveyer belt and a road paralleling it. Customers would drive their cars into this long room, pop the trunk, and hand me their cards. I would match up the bags, and place them in the trunk. The empty carts were placed on the bottom level of the conveyer belt, to be brought back to the Muzak-filled main level of the supermarket.

The room was filled with fumes and noise from the waiting cars and the interstate tunnel that was next to it. The incessant rattling and squeaking of thousands of metal rollers on the conveyer belts was irritating, although we got used to it (one thing I just realized -- upstairs where the customers were it was an actual belt, which was quiet, but down where we were it was those damn rollers, which were like 1950s-era metal roller skate wheels). We were paid $3.65/hour (minimum wage at the time). But the things that worried us from day to day was the cry of "mix" (human error, wrong bags placed in wrong car) or a spill.

Here's what happened with the spills. As the carts came from the 2f to 1f, they went through a series of turns, including at least one 90 degree turn and a full 180 at the bottom of a decline. This spot was where most of the spills took place. It was apparently unavoidable, owing to the layout of the store, the location of the slopes on the belt, the road and loading area, and the needs of the customers to get their cars loaded quickly. The nature of groceries (heavy/light loads, multiple packaging sizes, etc.) and the technology used at the time made it hard to find an easy fix to the problem. Watermelons rolling around the bottom of the carts were the worst.

I don't have any profound observations about this, other than spillage is a consideration for people who design and manage conveyer belts, and that the cost can be made manageable for both small and large systems. And these belts can be designed to last years or decades. The belt that we used in that market was in use for more than 20 years by the time I started working there in the 1980s, and it (or a similar system, using the same route) is still in use today, some 50 years after it was installed.

I think this could be more than just a substitute for responsibly exercising and interacting with a dog. I work at home and take my dog for plenty of walks and hikes, and do a lot of training with her, but she's very smart and food motivated, and loves all the Kong-like food dispensing puzzle toys. I suspect she would love this, and if it were a bit cheaper, I'd be all over this. (I could get a lot of $10 dog puzzles for the cost of this.)
Everything looks great! Except the click gesture. Besides warping the LCD (which would admittedly be mounted better in production), it seems like there's an unavoidable amount of strain on both wrists. Still, very cool! It's amazing how many awful interfaces we work with on a daily basis that could use some love like this.
Probably beta testing and researching impact on Twitter if those will grow (Twitter is semi-dependant on big number of 3rd party data providers providing great tools and free advertising).
the concept of "signing in" is not unique to a web page though, you also do it at a hotel. you also do it if you have dinner reservations. you also do it if you pick up a package at the post office. You also might do it when you show up for work to be put on the clock.

sign in, check in, clock in, log in. its all referring to a social process that is unique to that engagement between those two parties. What is performed can be widely different, so it makes sense to go to these sort of common words.
> Without the FDA, there would probably be numerous entities that evaluate food products and place their mark of approval on those products that pass a rigorous set of tests.

And who decides that those tests are rigorous? What prevents me from creating a more lenient, "anything but blatant toxins" goes certification agency that puts it's seal of approval on things?

For that matter, what prevents these agencies existing today, in parallel with the FDA? We already have things like fair trade coffee, for example.

How many agencies with rotating names do you want to keep up with?
I would find walking in a city to be a barrier to creativity. You have to keep engaging your concious, safety brain to deal with other pedestrians, road crossings and immunize your brain from all the advertising and noise that is trying to penetrate.

The ideal walking for me is somewhere outside with fresh air, but without constant interruptions to the flow of walking and thinking.

Ideally you want to be able to walk alone, but in a type of daydream where you're thinking about the problem at hand instead of spending many cycles on the process of walking. That means covering a well known route with few interruptions.

Luckily for me I have access to this type of environment right near my front door. But for those who don't, a treadmill could offer a similar experience, but I suspect the treadmill needs to be a good space (light, airy room, nice outlook from a window).

Lease would take if off balance sheet regardless of the value of the lease payments. Likely six-figure amount regardless ($4k/month x 24 months...etc).
I've spent a lot of time in the past year studying nutrition as I've tried to optimize my health. I don't believe there is a field that gets science more wrong and, as a result, whose meta-analyses are, to put it in Yudkowsky's words, more bullshit. Unfortunately, I don't think there is another field whose bullshit gets more media play, either (except maybe politicians, but that's a tautology).
This is true in the context of 2014, yes, but it's not necessarily historically true. My mom was basically computer-phobic before I got her an iPad in 2010, but in the '70s and early '80s, she was flat-out amazing on an electric typewriter and word processor. The word processor (a designated terminal, not a software package), was basically a really terrible command line with awful CP/M style menus and lots of complex key bindings. That, my mom could do. Windows 95-XP? Scared her shitless.

Another example. My mother-in-law worked at AT&T and then Bell South after the breakup for over 20 years. In the late '70s - late '80s, everything she did was on UNIX boxes. My husband literally spent parts of his childhood in data centers late at night while his mom did systems work.

My mother-in-law is very smart, but I still have to walk her through some stuff on a Mac or iPad. (And the Mac was a huge step for her, apparently she really struggled with Windows), yet at 74, this woman can still do UNIX commands and work in a shell in her sleep.

My late-Aunt was an engineer at CSX for 33 years. During the Year 2000 crisis, she was one of their senior COBOL leads (she got her CS degree in '74) and did a lot of the infrastructure work to fix those mainframes. But I remember her struggling with certain more "basic" computer skills, at least in the context of a Windows GUI.

It's about what you learn on. When I was in high school and college, I worked as a tech at a big box retailer, I would often have elderly people come in upgrading old machines, frustrated that they couldn't get the version if WordPerfect of Eudora or whatever to run on XP or whatever. Most of the time, those old programs were I intuitive by any standard, but it's what they knew.

If you grow up on a command line and continue to evolve what you use and try new apps, platforms and paradigms as they crop-up (which is the case for most if us here), you may not recognize the importance a first-system plays in future skills and usage, but it does. And that's why it's important to consider that the people growing up today won't enter a world where they type commands and wait for an output as SOP. Sure, some will learn those methods out of interest or for the efficiency that can provide, but people born today stwrt interfacing with systems very differently than we did generations ago, and that's why being aware of those paradigms is so key.

That doesn't mean you can't make something accessible that is CLI based - you can - but kids will enter pre-school knowing how to use an iPad -- and advanced usage too. It's the same way I was able to learn to program them VCR at 4 before I could read more than Dr. Seuss.

Our software needs to be accessible for them to use, because we're past the era of GUI being too expensice to program for or requiring too many resources.
Ride-sharing apps (i.e. Uber) ruled out in one state in Australia
Um, ChaplinJS (an MVC framework built on backbone) http://chaplinjs.org has done this sort of thing for two years. You have views and subviews, and you listen for events with @delegate (which maps to $.on using view's container) in each of those views. You almost never need to use global events, in fact it discourages their use.
I'd be interested to hear what you think of ChaplinJS - it's very small, but it does this kind of compartmentalized event thing really well. You can listen for events using @delegate in each view and subview, which is just a map to $.on using that view's DOM container.
large buys and sells will cause huge movements in thinly traded markets in which people "buy some and sit on it" (ie don't engage in transactions). I don't understand what you're getting at?
Sugar is the stuff life runs on but at our modern level of consumption it's undoubtedly the number one food toxin. Sugar is the secret to addicting the consumer and peddling high profit mush. It doesn't really matter much what form it's in sugar, evaporated cane juice (euphemistic term for what sugar actually IS), corn syrup a.ka. HFC (vilified but not substantively different than table sugar), molasses, wheat, corn starch, rice flour, etc. Modern wheat actually has a higher glycemic index than table sugar! Most of our food isn't toxic, just barely acceptable and sometimes poisonous e.g. food born illnesses. Our food is great at killing us slowly, lowering the quality of life and overall health and most of all attracting huge government $ubsidies! It's all about the money after all. Anyhow, I blathered on about this because it's probably the single most effective thing anyone could do for their health, keep their blood sugar stable and avoid cheap high glycemic addictive foods. BPA in tomato cans and other 'problems' deserve very low priority in relation to the sugar epidemic.
This is a good summary of the information trade-offs consumers deal with in deciding what foods to eat. The author identifies some of the worst purveyors of misinformation about food in this interesting article. As a good teacher, she tries to understand her students' preexisting misconceptions, misconceptions that often show up in Hacker News threads about food or nutrition.

I especially like the author's curated collection of hyperlinks in the article, which lead to several important sources of information on some of the hottest nutrition debates we often see here on Hacker News. Her recommendation of the Grist series on GMOs[1] is especially helpful.

I think you are evaluating 'go' based on feature set rather than the amount of friction a developer experience when using it to develop a good product.

C++ is fantastic but I personally experience far less friction when working with 'go' for most of my task.
I did know about and tried vagrant-lxc, and even the per 3rd party vagrant-docker implementations. None of them worked well or provided the right amount of ease of use and features that Vagrant and Docker provided.
People in general overestimate the technical competence of an average MIT computer science, engineering, mathematics student.
Succeeded - but is it still succeeding today?

I can't remember the last time I used Firefox intentionally. Chrome replaced it long ago.

As a web dev, I find myself more annoyed at the anomalies of Gecko everyday. I fix more Gecko related bugs than IE11 bugs, and that just feels wrong.

I don't expect this to be a popular opinion, but I have to say based on recent experience that if it wasn't for Chrome, I'd be using IE11 on a PC and Safari on a Mac. Firefox just feels too kludgy every time I use it.
Damn, now you have to start from the start and pick up on all those missed jokes.
I see the opposite, I see people struggling with Git when using different kinds of application (SourceTree and Tower)

Usually I end up helping them by using the command line. Sometimes I install ZSH first to get some nicer colors and autocomplete because they haven't even set that up yet.
> - No sentiment analysis

I doubt Twitter will ever do this mostly because of the scale of the problem and because I don't see why they would release it as a product for free (even if they came up with something solid).
It's a fat binary; it includes both 32-bit and 64-bit compiled code. Normally only the 64-bit code is used, but it can restart in 32-bit mode for compatibility with legacy plug-ins.
I totally disagree. You are holding these hypothetical companies to a standard above that of the FDA.

>You would be willing to trust what you put into your body to Consumer Reports? A magazine where, for a small fee, you can buy a positive review?

> All of their peers, of course, would also take money to buy good reviews, so no single agency, or group of agencies could be trust worthy for any real amount of the time.

Oh, so kind of how corporations spend money to lobby the FDA in their favor? Or large pharma companies bribe FDA regulators to approve only their drugs so they can have a monopoly on the market?

> has only its reputation and fear of its wrath to keep its value and budget

In what world is a government agency's reputation more important than a real business' bottom line? If the government doesn't do their job, they still take your money, everyone keeps their jobs, and the only recourse you have is to vote another representative in office who might try and change things. With a business, you stop giving them money, and they see the effect immediately.

> even if their service is completely illegitimate, a portion of the marketplace would be convinced of its validity,

Kind of like how the FDA uses the force of law to convince people that they actually look out for the consumer.

> And the best part, why would any of these agencies ever spend research money on their products?

If they didn't they would probably endorse bad products and go out of business.

Almost all of your criticisms could be applied to the FDA, but you think that they just need "reform." I don't need the government to tell me what to put in my body.
yup. and thanks!
>Given that, why would we expect feminists to be talking about the effect of sexual assault on males?

Because "feminism fights for men too!" is something we hear all the time.

>It's not their responsibility to do so, and I'm absolutely certain that most feminists would not object to male campaign groups which highlight the problem of male sexual assault.

You'd definitely be wrong about that: https://www.youtube.com/watch?v=FWgslugtDow
Is there any API for this? Twitter's analytics APIs are awful compared to things like FQL/Facebook Insights. The API doesn't even have access to basic reach numbers let alone things like organic storytellers.
They don't have it in boxes. There are also no guardrails. You might be looking at the conveyor belt in the picture with trees. That's not the Bou Craa belt.

Check out this video of a 10.5km limestone conveyor belt in China [0]. Notice the rollers have a tilt to them? I found a better photo of the belt itself on PBS. [1] if you look on the left hand side of the photo you can make out a cylindrical object beneath the belt. That is the roller, it has the a tilt to it, just like the Chinese belt. Any vibration will result in the load gathering toward the bottom the the belt. Most of what we see on the ground is small particles that are swept off of the belt by wind (Used to live near a port and a concrete factory. Lovely air quality, S&W Ready Mix.)

I think that could be improved with a higher resolution sensor, but the question is whether you could build such a thing while retaining space for physical keys.

IIRC, current gesture recognition still takes a couple hundred milliseconds on modern consumer touch screens (iPhones, etc.), especially for the "click" action.
Yeah, I used to use that all the time. 'System xyz is showing an abend'.

I had totally forgotten the term until now. Think I might throw it around a bit, see who knows what I'm on about.
Usually, you can build the game without them, up to the final packaging stage. Almost any game that is built on an engine can have all of the asset files swapped out without having to recompile anything, and as long as the file format and structure for assets is relatively stable there doesn't have to be a tight coupling between engine versions and asset versions except when doing QA and benchmarking.

This is one of the cases where git's inability to handle rewriting a public history is a pain. The art and programming departments should be able to develop along separate branches, and the programmers should be able to pull a tree from art that has everything between tags squashed (but in a reversible fashion in case there's a need to bisect something later).
The Chinese Military Is a Paper Dragon
This is actually happening in the organic food certification industry in Germany, where a ton of different certificates exist.

The EU-own certificate is the most lenient (AFAIK it allows of up 0.9% GM food in feed for animals if there is no alternative), the most strict one is the Demeter certificate, a pretty old one based on the slightly crazy teachings of Rudolf Steiner, complete with cosmic energy. Then there's Biokreis, Bioland, Biopark, Ecoland, Ecovin, and more, all of which have different requirements. No-one can keep up with these.
The consumer decides how rigorous the tests are by preferring foods with certain tests. Obviously, more rigorous tests will cost more, so the consumer can decide the optimal balance between price and testing. Companies that test too thoroughly, or more than consumers prefer, will drive the cost of food too high. Companies that test too little will not earn the trust of consumers, and health-conscious consumers will avoid those products.

> How many agencies with rotating names do you want to keep up with?

Well currently we have one (the FDA), and it is awful. I am willing to try a few more.
Prostitution should be legal
No, OP is saying installing an unsigned binary that is a package manager that has access to all of your system files is uncomfortable for some people.

I'd gladly fork it and replace it with a signed binary, but I'd want to ensure there isn't anything suspect in the project.

And seriously, I've never even heard of the kill switch being used for anything that wasn't malicious. Especially if it's not distorted in the Mac App Store.
The devs that created React are using React + Backbone.Router for Instagram's desktop site.

It's very easy to integrate Backbone.Router into a project.
Eh. I prefer natural scrolling. Took me two seconds to get used to and I don't like the 'normal' way anymore. On my work laptop, though, I keep it off because it reverses a mouse scroll wheel too, which I find abhorrent.
I'm not sure, but I would guess they could be either have V-shaped x-section or have sag in the middle to avoid having the material fall off the edges.
Ask HN: Need feedback for SoundCloud Wall
So SoundCloud Instant [1] was a huge hit (thank you HN). For a few weeks, I've been working on a very simple yet powerful problem - how do you discover new exciting music faster. So I made SoundCloud Wall (http://karan.github.io/SoundWall/).

It pulls music from SoundCloud and shows you multiple tracks at the same time - but all are muted. To unmute a song, you simply hover over it. The simple interface makes it dead-easy to search for, listen to, and discover music.

There were a lot of problems with making the app, and I tried to fix those. I am not ready to launch it yet, so I'm asking for your feedback.

Please use it and do tell me what you think of it. I'd love to improve it as much as I can.

Thank you HN! :)

I've found that forums seem to provide much of the knowledge previously transferred through Geocities. Detailed, human, non-encyclopedified information about almost anything is available spread through a vast quantity of subject-specific forums across the Internet rather than across webrings hosted on Geocities and the ilk.

I think part of the reason for the shift is that forums have gotten much more advanced: most include a personal homepage, photo gallery, and provisions for making "uber/FAQ" threads that easily surpass the most meticulously curated Geocities sites.

Genetic engineering is a very young science. It doesn't belong in our food yet. I'm not saying we should ban GMOs. But I think it's fair to label foods that have GMOs in them for those of us that don't want to take part in the giant human trial.

Electronic computing is a very young science. It doesn't belong in our homes yet. I'm not saying we should ban computers. But I think it's fair to label products that have computers in them for those of us that don't want to take part in the giant human trial.

Wireless telegraphy is a very young science. It doesn't belong in our air yet. I'm not saying we should ban wireless communication...

The electric car is a very young science. It doesn't belong on our roads yet...

At one point we were, as you pointed out, "all cool" with asbestos, lead paint, etc. Stop pretending like the inventions above aren't a big gamble!

etc., etc.

At this point, for all of the "young" inventions above, we have at least a decade and typically more of evidence showing either that the "young" inventions are not biologically harmful to human life, or are no more biologically harmful to human life than what they're replacing.

And the same is true of GMO food. The track record is solid, and the "wait and see" approach is essentially an infinitely-shifting goalpost (no matter how long we wait, and no matter how much data we get, it miraculously never seems to be quite long enough or quite enough data for those folks, and they impose standards of "safety" which would require essentially infinite time and data to comply with).

Thus the urge to label when the data does not support classifying GMO as a risk is essentially the urge to push people to give in to blind fear rather than evaluating available evidence, and encouraging reactions out of blind fear does not make good public policy.
I think you're probably right, but devil's advocating it, the height of the conveyor belt could vary, and sometimes be high enough off the ground that you couldn't safely jump off. If the run-up to the limekiln at the end of the conveyor belt is elevated for a long enough stretch, you might not realize the point at which you should jump off until it's too late.
