So... it turns out this has to do with Hydrochloric Acid being considered a Pesticide by the EPA since it can kill bacteria. This means they have to register its label for review and feedback with the EPA, as do companies that make bleach and a wide variety of other things.

http://www.epa.gov/pesticides/chem_search/ppls/005185-00494-...

The "inconsistent with its labeling" part deals with using it as a pesticide.

If you are found guilty (consumers have never been charged under this that I can find a reference to) as a non-commercial user, the penalty for the first time is a warning letter. According to the controlling Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), fines can only be administered if you violate usage another time after receiving a written warning from the EPA.

And none of this has anything whatsoever to do with what she is being charged with. She is not being charged under the Insecticide, Fungicide, and Rodenticide Act.

Those concerned that the FIFRA means you must strictly limit use of EPA controlled pesticide products to specified uses only should consider the fact that since ordinary tissue paper is considered to control the spread of viruses when you have a cold, it is regulated as a pesticide as well under the EPA.

Notice this one allowing an exception - Kleenex will be allowed to remove the ordinarily required "Keep out of reach of children" warning for their EPA regulated pesticide known as Kleenex brand tissue paper.

http://www.epa.gov/pesticides/chem_search/ppls/009402-00010-...

According to the theory that this act strictly controls usage, using Kleenex to clean your glasses is a violation of federal law as that usage is not listed on the label.

Of course we all know that is not the case.
Why is pop startup culture so web centric?
I have found that the popular notion of startups is so web centric. While I understand that these kinds of business are quick to build, and provide valuable services, why is everyone so bent on these pursuits instead of a wide variety of things?
The biggest problem with web hosting providers' email services is the lack of effective spam filters similar to Gmail's though.
It's 2 AM here, but I'm mustering up the strength to write this because the answer provided here is so detailed, so specific to my question. Thank you so much for taking the time to write all that. I am still reading it over and over to fully comprehend it all, there's a lot to take in.

I see now the thinking flow I have to change, I have been window shopping so to speak with frameworks, stacks.

iron.io is what I think will be used for converting long asynchronous task.

I wouldn't mindd specific technology stacks. it's either node.js or python. I built something in Flask (god bless it's heart) but I don't know if there are others who have made it scalable...

Please argue on why or shut up.

The fact is you don't know anymore than us if govs will shut down the endpoints with "real world", or if BTC will succeed to create its own ecosystem and reach the point where it don't need dollars anymore.

All we can do is argue and convince ourselves if BTC is a good bet or a disastrous bet. Something you obviously can't if you threat everyone insane.

I got a job offer and left.

Every discussion he would bring up me being negative and it started to grind on me even in my exit interview.

I was sick of having that badge and no one else saying the truth, I ended up being quiet and the manager didn't like that either.

My new job is much better, I get the work done and everyone is happy. I'm upfront with my views.

Even just mentioning an issue was negative, when I said we need to earmark it and look at solving it.
The very premise of this article is a huge technical error that misreads the Internet Census report. for eg.

> The map is further limited to Linux-based computers with a certain amount of processing power. And finally, because of the parameters of the hack, it shows some amount of bias towards naive users who don't put passwords on their computers.

The author is confusing the machines that were taken over as part of the botnet in order to scale the mapping, as opposed to the machines that were actually mapped (the entire IPv4 space) [1].

Again:

> the researcher hacked into nearly half a million computers so that he could ping each one

He hacked the machines so he could ping other machines. This error is made throughout the article:

> But on a general, half-a-million-computer level, this is what the Internet looks

The map below this statement is the map of the entire IPv4 space, not just the botnet.

> but IPv4 is still pretty common.

Right, ya think? That is all that was mapped, IPv4.

> Because at the end of the day, there's a fair amount of debate over what the real state of play on the Internet looks like. Some say it's a map of connections, others say it's a Tootsie Roll Pop made up of layer upon layer of activity.

Here he is comparing a geographic map of IPv4 addresses and a routing map, and in the second analogy confuses a geographic IPv4 map with a link map across popular websites.

[1] Mapping the entire IPv4 space from a single machine would take decades. What the researcher did, which as far as I know hasn't been done before, is he created a botnet of 400,000 machines to help him in the task. The task of pinging and probing the internet was divided up across the botnet. With the large botnet he could not only ping scan the entire IPv4 space, but he could probe the most common service ports at each responding machine and get it done in hours, rather than decades. The article confuses the botnet with the survey results.

That's a stretch. If it were not valuable monetarily, its price would be similar to other difficult-to-extract, heavy metals with a long list of unique properties, like Iridium or Rhenium, neither monetary, and both around $400 an ounce.

Yes, but I don't see a difference between this and Steam on PC. An appstore is just an easy way to download apps. Steam can make a special homepage on Steam PC + a badge + a free valve game for every gamer using the app, and the google interdiction will just be nothing.

First they find support for the hypothesis that the place of women in society can change very quickly because their function in society changes.

Then they find support for the opposing hypothesis that such changes in society have long lasting effects, i.e., that the position of women in society does not change quickly.

Finally they place both opposing hypotheses in a single narrative.

To me, this is a major inconsistency, perhaps only due to the journalist rather than the scientists. Both hypotheses should be discarded since neither fits all the observations.
Ask HN: Anyone else seeing all Google links the same colour?
This morning I did a simple google search, but all the links looks a somewhat dull blue, somewhere between visited and not visited colours.

First I thought I was too far way from my monitor. Then I thought my monitor wasn't working. Then I thought I might be getting a migraine (as that usually starts with my vision).

But after trying another browser it looked normal. Turns out, that when you're logged in to google, the links are all the same colour.

Anyone else see the same or know what's going on?

The BBC has weird ideas about how people steal software (BBC Hustle)
I used to do this when I worked for the post office (not in the US) and it was by far the dullest thing I have ever done. Truly loathsome work. It was referred to as "coding".

There were rules in place so you could only do it for 20 minutes at a stretch and only a couple of times (three?) per shift. Presumably this had to do with the fact that the quality - which was a problem - would collapse otherwise. You needed to keep a low average time per letter or you would get booted off coding duties. I can't remember exactly how long, but you needed to be able to code a letter in a matter of seconds.

The American setup looks a lot more hardcore (six screens?!) than the one I used though. Pretty sure the application was written in Visual Basic.

The machines which sort mail are pretty bad-ass. Not only can they sort by postcode, but also by address so the mail comes out in the order in which the mailman visits each building on his route.
Interesting. But my original point stands: if you don't sell your car, you're looking at a $20k bill a few years down the line, and on the page Tesla are happy to talk about total-cost-of-ownership of their competitors, they're not telling you about that $20k replacement.
Good luck with that. BTW aren't you going to point out once again that for example in Australia all the data comes from Tele Atlas and Whereis?

> The debug stats in the top corner showed that he was using 60-80KB/sec of bandwidth while playing. He explained that each frame was being sent down over the internet from a co-lo center.

I'm wondering what kind of miracle makes a video game display streamable at that speed with any form of acceptable quality (not even talking about 1080p@60Hz), especially given the following:

> The codec in the prototype was nothing more than a series of JPEG images sent at 15-60+ frames per second.

A single acceptably lossy typical JPEG game shot at 1080p is north of 600~800kB, while even one at 720p (typical of a '08 laptop) come up being 150~300kB. Below that you start to get noticeable artifacts.

Even if the game engine/platform knows what has been updated and only send deltas of sort (again taking the series of JPEG images case), you still have to account for the worst case, that is basically the whole screen changes at once, sixty times per second.

And indeed, in the Steam video, you can see throughput data at the top: when nothing's moving the value is as expected very low, but you immediately notice the peak at 9Mbps when the L4D video ends[0], with typical values during the video at 4~6Mbps, which is much more inline with a 1080p stream.
Even the fading Source logo produces a 2.5Mbps stream (which produces very small diff areas), at 85% quality. There seems to be some cap at 48Mbps.

You can also see various timings, and the adaptative compression kicking in on the 9Mbps section, where you can read:

capture: 2.196ms
encode: 4.811ms
decode: 6ms
quality: 70%

There seems to be another timing value at the beginning, with an "encryption" label, hovering at 9ms.

BTW, what's with the monotonically increasing with time stream = ${p}% value? That makes it look like a streamed video, not an interactive one. Not being suspicious but it felt weird.

That's probably a safety precaution but if it is like you describe it is also a risk. It could be a safety precaution to make sure that accounts do not eventually become compromised in the case of deceased person.

But if the account is deleted entirely that could indicate the address can be re-used and in that case any password reset mails and other important email might land in the new owner of the address' inbox.
Ask HN: Measuring CPA with mobile apps
Hello HN,

I'm really curious to understand the different tips and techniques you use to measure CPA (Cost Per Customer Acquisition) for your startup business.

My business is focused on delivering a set of mobile products to a distinct (almost niche) user base and I'm on a mission to really understand my key metrics, CPA being the first. However as we deliver our solution via a third party (in this case the app store) I feel that we are are at a disadvantage to our SaaS counterparts.

If I look at our customer flow, its a pretty familiar story starting with some lead generation activity (in this case Google ads):

Adwords > Dedicated landing page > Link to App stores > Download / install > Register

Now I can measure everything in detail up to the point the user leaves our ecosystem and ends up at the Apple or Google store. So I am curious, how do you manage this if at all or am I expecting too much?
> Maps/Earth are cool, but they've stagnated, Barely changed in the last few years.

That's a feature, not a bug.

I actually like the way maps works right now, I would not want change just for its own sake.

Or in Clojure:

Widely is not needed. The Future, that's conceptual, not factual.

In order to become "the future of money", it only need one or two big organization using BTC, a derived one, or their own virtual currency, or to survive to direct organized attacks the day it will obstruct some important people.

In the same way of erlang, ocaml and haskell, seen as futuristic languages, BTC /can/ be a futuristic money.
re your footnote, there was a relatively recent article[1] on 'mapping the IPv4 space' via ICMP ping, which proved it was entirely feasible, although it pales in comparison to the effort required for a full portscan of each host (and the benefits of a massive pool of scanning hosts to elude rate based IDS/firewalling effects)

This is very cool. I work with information visualization/visual analytics, which provides some very powerful analysis tools to handle situations where you have to make decisions based on heavily multi-dimensional data.

This research hasn't been as heavily applied in practice as it could be, but it's obvious that it has huge potential. This article is a textbook example of what sorts of situations these analysis techniques are good for. (Except that there are no textbooks on this yet, but that's a minor detail). The major point is that these techniques will show you trends and correlations, which is usually enough information in real life. People will yell "correlation does not equal causation" all day, but often correlation is enough to be able to conduct a closer investigation in the right place or ask the right follow-up questions.
What attracted me to BeOS on those days was somehow the Amiga feeling I felt in the platform, hard to explain.

And as someone that will gladly do C++ development, it felt really nice to have an OS done in it.

But I feel Apple would have needed a different type of marketing to attract developers back then.

When I was at CERN they were selling us "It is BSD/NeXT with a nice UI" story.

Thanks for the link, by the way.
Well, firstly it's vice. I wouldn't place too much stock in the fact-checking capabilities of that organisation.

Having mined the data, it's not the entire IPv4 space and there are substantial duplicates and missing parts. That's not to say it's not an interesting project (albeit shadily done) but the accuracy of the data is suspect (as things change over time and this was done over around a 6 month period).

If you have the space I do highly recommend downloading it though, there's some fantastic insights in there.
This is false.
Not only Tab doesn't automatically send the email but Google has not overwrittern anything. This is the default behaviour on a web page. Pressing Tab selects the next interactive element on a web page (a link, form elemnts etc.) and pressing space/enter activates it.
I'm guessing you press tab expecting to indent something, write a word and then press space to begin the next one which actually sends the message.
This is how forms on a webpage work and AFAIR this is how the compose function in gmail always worked. I think i have seen a couple of WYSIWYG text editors that "capture" the tab keypress and actually ident the text but this is far from the norm.

I think this points to a seperate issue as well: Often times we have a choice to express the same thing through types or through state. As the influence of functional languages grows, we tend to choose types more often.

It wouldn't be surprising to have a ReadOnlyFile type and a ReadWriteFile type. This can easily be justified because an individual file object doesn't need to change its read/write property after it has been created. But conceptually, files can be written to, just not always.

Another example makes that clearer. Adults can do things that minors can't. So, for instance, a signContract() method would have to go on the Adult type not on the Person type. But people grow older, so at any point in time some objects conceputally change their type from Minor to Adult.

Technically this is not a difficult problem to solve. But it shows the disconnect between our natural language concepts and the ever more type centered way of modelling we use in modern software design.
