"NSF certifies three basic products in the fluoridation category:
1. Fluorosilicic Acid (aka Fluosilicic Acid or Hydrofluosilicic Acid)
2. Sodium Fluorosilicate (aka Sodium Silicofluoride)
3. Sodium Fluoride
All three product types dissociate in water to form sodium, fluoride, and in the case of the first two, silicate ions."

"The NSF toxicology review for a water treatment product considers all chemical ingredients in the product, as well as the manufacturing process, processing aids, and other factors that have an impact on the chemicals attributable to the products present in the finished drinking water. The identified chemicals of interest are subsequently evaluated during testing of the product.... These tanker trucks, transfer terminals and rail cars are potential sources of contamination. Therefore, NSF also inspects, samples, tests, and certifies products at rail transfer and storage depots...... In summary, the majority of fluoridation products as a class, based on NSF test results, do not contribute measurable amounts of arsenic, lead, other heavy metals, or radionuclides to the drinking water."

"The identified chemicals of interest are subsequently evaluated during testing of the product. For example, fluosilicic acid is produced by adding sulfuric acid to phosphate ore."

In the table presented, the current chemicals tested for are: Antimony, Arsenic, Barium, Beryllium, Cadmium, Chromium, Copper, Lead, Mercury, Radionuclides – alpha pCi/L, Radionuclides – beta mrem/yr, Selenium, Thallium.

What else is going to be in the phosphate ore that could come into the water? To me that test range looks too small. How pure is the sulfuric acid used to dissolve the phosphate? Also, what sort of byproducts are going to occur as the fluoride additives and sulfuric acid corrode their containers?

I don't live in the USA but these are the sort of questions I'd be asking, and as mentioned elsewhere, I'd want to see realtime and comprehensive information on the additives used - and alerts if something strange or unwanted is found. I think it's going to be more difficult to test tap water itself for such additives, so I'd suggest testing and displaying the actual additives before placed in the water - and from there it's going to be straightforward to determine concentrations. Personally, I wouldn't be accepting the NSF/ANSI Standard 60 as it currently stands... from how I perceive it. It was devised in 1988. This sort of extra testing would have to come on top of it, likely on a small scale by individual plants interested.

Finally, I would start thinking about testing air quality... not final air quality... but the actual additives used in chemtrails in a realtime manner, just like with water additives. You can argue about if chemtrails are real or not, I am just asking... "whatever is coming out the back of those planes... I want to know what it contains, because I am inhaling it."
Very nice comment, thank you. Look my opinion is that cloud computing is really an important skill that you need in your resume, and if you take a look at 90% of technical job positions today you'll find that they cite AWS skills when they speak about cloud architect, system administrator and even developer position.

The reason is quite simple, AWS is still the leader in the public cloud market and we have thousands of members that are looking for training to pass the certifications (actually we have a dedicated product called CloudCareer for AWS for that).

You're right, they are changing very fast but that's part of the tech world and definitely something that we have already saw for other platforms.

Think about all the companies like Trendmicro or Reverbed that are building product for AWS or Google or Azure, on top of these platforms. Having an AWS certification is really the first goal there and the first need for millions of companies. The same is going to happen with Google Cloud, Azure and so on.

For CloudAcademy.com we have a great challenge about this point: we are developing a technology to keep our content automatically updated with the help of the community and of our algorithms.

The high tax liability claims are based off of projected revenue (in a very market-optimistic year) -- not actual revenue. This is why usually the actual tax liability is significantly less.
Sure, those can be valid reasons. None of that was in the argument I was replying to. That argument was "without a government-sanctioned monopoly you won't get a taxi service and people will start drunk driving."

I'm from Sweden where the taxi market is mostly deregulated, with the only remaining regulations being in the interest of consumer protection - extended driver's license, approved taximeters and clearly displayed standardized pricing information. There are a few problems with tourists who don't understand the pricing information getting on taxis with rip-off rates, but aside from that it works well. There's a number of full time taxi drivers, and during busy periods (evenings weekends) there's a contingent of part timers who get in a car to skim off the lucrative periods and add capacity. From the discussions I've seen in "hey anyone tried becoming a taxi driver" threads in Swedish forums, it's a career you can make a living in.

I've been in places with high levels of regulation (:cough: san francisco :cough:) where I've experienced half the points you take up, whereas I haven't experienced any of those in Sweden. As usual, it's more a case of "good regulation vs bad regulation" instead of the more typical political dichotomy of "no regulation vs lots of regulation".

I'm not from Cheerp, but it looks like the main difference is this (taken from their front page):

Dynamic memory management. C++ objects are translated directly to JS objects, without the proxy of an emulated, flat memory space. Allow your applications to exploit the JavaScript VM garbage collector and co-exist with fair, on-demand memory allocation.

I don't think that's a good thing though, since the reason why emscripten compiled code is fast is because it has a flat memory space and doesn't create expensive JS objects.

Only advantage IMHO is that you don't need to allocate a big chunk of memory ahead of time (although I think emscripten still allows a growable heap as an option, but with a performance penalty).

What places have said sorts of sunscreen?
Tech related aside, the design of sun resistant clothing that doesn't overheat you is an area that is seeing a lot of advancement recently.

Polyester fabrics with texture to keep some air under the fabric and thin merino wool poly blends (that have a bit of natural texture) really seem to work. They can act almost like a mesh that still blocks the sun.
While everybody can understand the anger, the bad behaviors of some individuals must not be generalized to a profession, can it? Maybe "Demo Day attendees" would be more appropriate than investors.

Practically every operation in Python starts with a hashtable lookup. Global and local environments are hashtables, modules are hashtables, objects are hashtables. Eventually you get down to C, which is usually very good---the hashtable implementation in particular---but for a lot of Python code the extra indirections are expensive. That's also why it is hard to optimize.

In this particular case, I don't think it's the problem, though. Just something to keep in mind.
>Y Combinator has a zero tolerance policy for inappropriate sexual or romantic behavior from investors toward founders.

This implies that some sexual or romantic behavior from investors toward founders would be considered appropriate. If that's not the intended message, inappropriate should be replaced with something like 'any and all'.

While I'm not in any startup circles at the moment I would be curious for some clarification. Is it ever acceptable for an investor to pursue a romantic relationship with a founder? After the founder is funded (by another investor), for example. Or if the founder initiates?

EDIT: anyone want to explain the down votes? I point out what I find to be a confusing point in the message and ask for clarification. I didn't even express an opinion on the overall matter one way or the other. I simply asked for clarification and made what I thought was a useful suggestion. In what way is anything I wrote offensive or otherwise worthy of being down voted?

The amount of sun exposure needed to max out skin-produced vitamin D in sunny regions during the summer (which is where/when most people would use sunscreen) is very low anyway. Somewhere around 30 minutes of exposure per week does it. People usually put on sunscreen when intending to be out in the sun for hours, and there is definitely no need to have hours of exposure to summer sun from the perspective of Vitamin D production.
<i>- Property tax applies to all real estate, not just businesses, so I'm not sure what this has to do with business taxes.</i>

Actually, Texas (or perhaps local authorities) levies a property tax on all business assets. If you host a website on a server in texas, they will levy a property tax on the server. Sometimes that's paid by the hosting firm. Sometimes, it's passed on to clients.

If you don't believe me, look it up.
> As a small business the value of protection you receive from the state is incalculably larger than the price you pay.

Unless you are in CA and are a small or side business with little revenue (thinking side consulting gigs, etc).

The minimum tax liability + biz license and other fees (base tax of $800 or more depending on revenue + biz license + other fees) quickly makes it not worth incorporating in CA if you can avoid it. That is, unless you are making more than a few thousand a year from your side gig.
Using an hourglass to explain programmer disruption to the layman
First, be persistent. Accountants and their secretaries are people. They don't necessarily have the best handle on all of their communication streams.

Second, there are these things call "telephone books" that list the "telephone numbers" of businesses in a section called the "yellow pages". Sorry, snark aside, it's pretty easy to find info about the accountants in your area (and I would prioritize finding one that is close, so you can easily visit their offices to drop off last-minute paperwork). Pick a few in your are and go visit their offices. Talk to them. See if your bullshit detector goes off.
A television show isn't a justification for real life behavior.
Look, I'm sorry if this sounds snarky, but the burden of proof definitely has to be on the person trying to censor rather than the person being censored. Otherwise we end up in an endless political correctness circle jerk where no one can propose anything of substance without being shamed for it.

That being said, it's trivial to write a coherent sounding argument with the exact opposite conclusion. I won't bore you with the details, but it works because people (especially in times of stress) will often react completely differently in response to the same stimuli. Psychology arguments that sound coherent and clever are fun, but without proper scientific study they're more often wrong than right.
> is inappropriate investor behavior illegal?

Depends on what behavior we're talking about, but the simplest answer is no - lots of inappropriate behavior is not illegal.

It's not an investor-founder story, but a related and eye-opening read is the story from the co-founder of Meebo, titled "Why I Now Believe the Glass Ceiling Is Real"[0].

No it doesn't. Grammatically, the "inappropriate" is used for vocal emphasis.

Your first sentence is a bit off. I for one didn't know this needed to be done. I was under the general impression that investors that work with YC were high caliber and professional. It never crossed my mind that anyone associated with YC would be anything but that. Sad that my high level of expectations are so obviously wrong.
It sounds like your saying, "Why isn't there a VC firm that states outright you might be sexually harassed to receive funding"

How are you possibly surprised that isn't a thing...? Of course it's not and never could or should be. You're comment is being down-voted because it's pretty ridiculous; the extremely low possibility(non-existant) coupled with the offensive nature of the concept as a whole makes it mind-boggling that someone would even consider it worth pondering in the first place.
The links you pasted show Firefox currently being 3x faster than Chrome when running asm.js code, so I'm not sure what your point is. V8 is good at generating fast code without the hints, but obviously the extra restrictions help the optimizer. Even Google admits this when they try to promote Dart.

asm.js does little for you if you write "real JS", but this thread is about cross-compiling other languages, which clearly has real world use.
You didn't miss much.
That's not true. In the controlled setting, sunscreen affects ability of skin to make vitamin D, by about half: http://www.ncbi.nlm.nih.gov/pubmed/22512875

Sunbathers who use sunscreen tend to not have lower vitamin D levels than non-sunbathers who don't use sunscreen, because, well, people who don't use sunscreen don't get sun exposure anyhow.

Also, when the human genome was evolving, sun exposure accounted for 90%+ of all vitamin D intake, diet accounted for less than 10%. We know this by looking at the diets and vitamin D levels of hunter gatherers.

That is so racist and discriminatory I don't even know where to start. It's no different than to assume the worst of "black" people or women.

The worst part it is the way it has become acceptable to bash "white dudes" for the color of their skins and/or their gender.
There are always 'circles' where this is considered appropriate behaviour.

In the fashion world there are a few photographers which almost openly do this, known to us mostly because they got so used to it they put their dick in a girls mouth unannounced and rather than suck it she talked to the press about it. [1]

An old colleague worked at an IT company thirty years or so ago and on the upper management floor, as he described it, the secretaries were all paid $200k/yr and up to be, essentially, professional hookers.

It is almost certainly a problem in some circles in the tech investors industry as well.

This is just a, very welcome, statement to tell investors that if they want to be such an investor they'll be locked out of YC forever and to tell founders that they can expect to be backed up when they report this.

I have long believed that true communication is only possible between equals in a venue that everyone considers safe.

If you have the ability to significantly change someone else's life, they will produce submissive and defensive behavior just as though you had them actually pinned to the ground while baring your teeth. In the end, a manager is just a skilled laborer with a different set of skills.

There is no particular reason why the ability to organize a labor force should automatically result in authority over it. The manager does not always need to be the boss. I imagine that some business decisions would turn out differently if they had to be backed up with evidence and argument rather than authority and the threat of job loss.
This sounds super handy for situations like honeypots. Take a /24, assign the hosts you actually have, and then spoof the rest to another server which fakes open SMTP, HTTPS, etc. connections, or which replies to every connection attempt (slowly!) with a successful (if slow!) open.

There's an iptables module called tarpit[1], which takes advantage of some peculiarities of the TCP protocol to essentially prevent the remote host from closing the connection, which can force (conforming?) TCP clients to take 12-24 minutes to timeout every connection. It can make portscanning unpleasantly expensive and time-consuming.

Is it ever acceptable for an investor to pursue a romantic relationship with a founder? After the founder is funded (by another investor), for example. Or if the founder initiates?

As a founder and MD of a company, quite simply, the answer is a bold NO.

Most of the opposite gender population is outside your company (or pool of possible investments). If you feel the urge, fish there, not in the tiny pond which you have a weird power relationship with. Getting romantically involved with people inside your company or which you're considering for investment is reprehensibly bad judgement as an owner or anyone in a position of authority and should obviously look like a Really Bad Idea (tm) to you if you are in that position of authority.

It's a bit like the old "should a teacher date a student" chestnut. Whether or not the student "initiates" is irrelevant. Just stay away from it, it's a terrible idea. If the founder/student "initiates", then they are the one acting inappropriately, and your thought should not be "hmm, maybe I should go along", it should be "oh shit, this could be a big problem, how do I get out of this tactfully?"
In my opinion this is overly harsh.

I would revise to: If you don't understand why this needs to be done, you should read more and learn more until you do understand.
They could take the easy way out: publicize an API, and let people write their own opensource clients. Would work well with the linux prosumer group.

Professional athletes and drug use. Police officers and violence. Clergy and child sexual abuse. As a percentage, those situations are extreme minorities, but it's important to aggressively address serious issues that exist in an industry, and not shy away for fear of generalizing.
"This implies that some sexual or romantic behavior from investors toward founders would be considered appropriate."

That's a stretch. I think most reasonable individuals reading the statement would conclude that "inappropriate" is an emphatic descriptor, and not a categorical divider.
Agreed on the awesome post front and one of the reasons I became a customer in the first place. I'm unlikely to renew my annual subscription this year, though, because they don't support external drives/NAS. I don't like cluttering up my laptop with photos so have to transfer everything I need backing up to my rarely used desktop PC, which is a pain. I can understand there's a risk people might abuse networked storage by backing up multiple devices but in my case I wouldn't mind paying more for that service or simply based on actual GBs stored.

Edit: They do support external drives but not NAS. My bad.

Your analogy makes no sense.

If you've read any of the previous Y Combinator statements on sexism against founders, you'd know that position being taken here is one of removing inefficiencies in the system. All the women being literally chased out by male investors who are seriously abusing their power just to get their rocks off is considered to be a huge opportunity cost. A female founder conference is a workaround, and it makes you sound really out of touch to complain about it.

No, the "inappropriate" is a qualifier...so there is an implication that certain behaviors are appropriate. There are many ways the statement could have been worded to state a zero-tolerance attitude...this was not one of them.
I think it does imply exactly that but don't really know how to argue the point. But regardless of whether it actually does or not, I doubt I'm the only one that thinks it does and thus if that wasn't their intent they should update the message to be more clear.

For certain workloads these storage pods are much, much cheaper than S3. Anything where you are storing files that rapidly become stale, but still need to be instantly accessible for the rare random request.

I've only looked at it from the perspective of video files, though. Where I work we add a gigabyte of data per user per month. Eventually our S3 storage bill is going to be our largest cost due to compounding growth.

It is extremely important to celebrate successes (of the team and individuals), but a good manager needs to know when and how to correct behavior as well.

One of the best ways I've ever seen is simply asking the right questions (What did they think of the <recent event>? How could it have been handled better? How could it have been prevented?) People get very defensive and find excuses if you tell them they fucked up, but if they can admit it themselves they tend to correct their own behavior.
