A small PSA: "Brita" brand water filters seem to be very popular in US, but they're also some of the worst in tests. For example in this test ...

http://www.goodhousekeeping.com/health-products/g684/water-f...?

... "Brita" filters were found to remove around 55% of PFOA, whereas "ZeroWater" filters remove more than 95%. I.e. "Brita" filters leave 9x more stuff in the water. The performance difference is similar for other unwanted stuff, like lead.

> The ABC here in Australia

As an Australian, aside from their news which last I checked doesn't get the same kind of views as the private companies I would disagree.

Maybe the parents enjoy ABC1 or whatever plays kids shows all day but I find the quality of their original shows to be quite poor and their flagships like QANDA have really gone off the rails in the last few years.

I'm from Canada, and all I can say is I wish the doctors up here actually listened to your opinion on your own medical condition.

While it is important to consult and listen to doctors, I do think people trust their doctors too much. People should always field second opinions, especially before major interventions. Also, people shouldn't discount their own understandings of their condition.

But seriously, up in Canada I feel like we have a 3rd world medical system for dealing with chronic health conditions. For acute medical conditions, we're amongst the best in the world. But if it's chronic? Or if we cannot diagnose it? Good f'n luck, my friend.
Been using groff ms for years, switched to mom a couple of years ago. I highly recommend it. I have switched almost completely from pdfLatex to groff mom.

Groff comes with (almost) every *nix, although some you may have to install specifically (Ubuntu?), especially the mom macros although the groff_mom manpage may suggest it is already there.

The only thing that I find a hassle is the setting up of font families. Mom docs don't seem to say much on this.

Groff is much faster than Latex, and doesn't throw weird errors.

And thanks to Schaffter for this very useful macro. Schaffter used to have a donation page somewhere, can't see it now.
The strange thing is, many doctors dont take good care of themselves. They smoke, they drink, etc.
Neat. Following the video trail someone said they're pretty commonish in SEAsia and that people might have some trees in their back yards in So FL.
Thank you, that actually backs up what I've been saying:

> competition: the applicants wish to ensure that the potential for competition and innovation in the emerging market for mobile payments is maintained. Therefore, they wish to collectively negotiate in response to any technological or other
exclusivity that a Third Party Wallet Provider may seek to impose by:

> - refusing, restricting or failing to provide software access to any payment
functionality built into devices manufactured by or for, or operating systems
developed or distributed by, the Third Party Wallet Provider, for example
NFC functionality; and/or

> - otherwise preventing or impeding card issuers from developing, deploying or
participating in any other mobile payment or mobile wallet services or Third
Party Wallets on any mobile devices or platforms;

They're mainly concerned with fraud standards and making sure nobody (Apple) tries to limit access to their platform.

As for your boycotting and "strong arm" claims, this document shows that scope is significantly narrower than you're implying:

> Accordingly, the applicants seek authorisation to: [...]

> enter into a limited form of collective boycott where the applicants will agree not to negotiate with the relevant Third Party Wallet Provider on an individual basis while collective negotiations with that Third Party Wallet Provider are ongoing.

The "boycott" in this document is referring solely to individual negotiation. i.e. Bank1 can't go behind the other banks' back and sweeten the deal while they're negotiating as a group.

Nothing measured in parts per trillion is "saturating the environment," and everything including plain water has "unknown effects" in one context or another. The precautionary principle is epistemologically bankrupt.

That question haunts all of us... For instance... Lets say you need to query a db to get 4 known sets of things aggregated by other things... That should scream at you "in clause with the known params and group by" or.... if you take an approach I saw recently you spawn 4 worker threads each querying the same tables but with one of those 4 params then combining the records.... I'm afraid this board may constitute the remaining sane individuals...

Edit those known params were all used as a param for the same column

They designed the system to support 1,000,000 users per hour over 24 hours.

what into the irs then walk into an h&r block. i've done this one year when my taxes were particularly complicated and someone i had worked for was trying to screw me over on taxes. after a long wait, the guy at h&r block said there was nothing to be done. on the other hand i walked right into the irs, was given the form and assisted in filling it out. in the end i saved a couple thousand dollars.

i never was that excited to go to h&r block, but figured they'd be an extra pair of eyes to catch anything stupid. now i don't bother. i've been to the irs a couple times since with my tax questions and get good answers from them. also haven't ever had a problem with the DMV. the VA, i've no experience with.

Maybe it takes an upstart to displace an incumbent rather than the incumbent reinventing itself. So for example you have Amazon vs Wal*Mart, Tesla vs GM... Now, some incumbets do have enough time to reconfigure (as WalMart is trying).

Ermm, my city's well closest to me has the following:

MRL	Tested
chromium	0.2	0.67
vanadium	0.2	1.1
strontium	0.3	960
chromium-6	0.03	0.44
chlorate	20	190
molybdenum	1	8.7

[Edit] to change "Allowable" to "MRL":

"The lowest amount of an analyte in a sample that can be quantitatively determined with stated, acceptable precision and accuracy under stated analytical conditions (i.e. the lower limit of quantitation). Therefore, analyses are calibrated to the MRL, or lower. To take into account day-to-day fluctuations in instrument sensitivity, analyst performance, and other factors, the MRL is established at three times the MDL (or greater)."

[Edit 2] In my town's overall distribution system there are multiple samples above the allowable Reference Concentration. The highest were:

Tested	Allowable
strontium	1900	1500
chlorate	410	210
ConsumerSearch also did a meta review of the best water filters:

They wrote a buying guide for your next water filter:

Since people seem curious how to analyze this for their locale, the best I could come up with (using the raw data at https://www.epa.gov/sites/production/files/2015-09/ucmr-3-oc... ) was:

1. Search zipcode in UCMR3_ZipCodes.txt, obtain PWSID.

2. Filter by PWSID in UCMR3_All.txt.

3. Filter that result by rows containing "=" (which means at or above minimum reporting level)

4. Don't panic.

5. Compare AnalyticalResultsValue column to the Reference Concentration in ucmr3-data-summary-april-2016.pdf. If its under the Reference Concentration then you're safe, within the limits of how incomplete their reference concentations are. The document specifically states:

> The intent of the following table is to identify draft UCMR reference concentrations, where possible, to provide context around the detection of a particular UCMR contaminant above the MRL. The draft reference concentration does not represent an “action level” (EPA requires no particular action1,2 based simply on the fact that UCMR monitoring results exceed draft reference concentrations), nor should the draft reference concentration be interpreted as any indication of an Agency intent to establish a future drinking water regulation for the contaminant at this or any other level.

The minimal reporting level seems to be based on how small an amount is detectable, not harmful. The reference concentration appears to be a best guess at the moment for what a maximum safe amount is.

My zipcode for example came up with several of these above the MRL but below the reference concentration. Enjoy.

That's interesting. Anyone know offhand how that works?
This is what makes PFA molecules so potentially dangerous: they don't behave like anything we've seen in natural biochemistry. Since they have both a hydrophobic carbon chain and a hydrophilic functional group containing fluorine, no known protein can break them down and no known biomechanical mechanism can filter them out so they remain in the blood indefinitely. At the same time, however, the carbon chain and functional group are free to bind onto other proteins as long as the molecules are oriented in the right way, which invariably prevents the other protein from functioning correctly.
Only if the chance of capture is low. If people got cought 9 times out of 10 I don't think they would have that hobby.
Not sure if you're joking, since we're all dying, but if you really want to know what it means see my other comment.
Those look like the MRLs, not the reference concentrations. For example Chlorate isn't (maybe) a cause for concern unless above 210, not 20.

Repeaters and equalizers. They go up to 8 fiber pairs, and are probably the most expensive single component for long cables. You need separate amplifiers/equalizers for each single fiber, so the cost strongly depends on the number of strands.

Since these repeaters are typically placed every 50-80km, there's a significant number of them in long systems and powering them becomes a challenge. These cables usually operate around 10kV DC at 1-2 amps, and I'm not sure how realistic it would be to go higher. The wire resistance losses are probably already more than 70% of the voltage budget, so you can't really use more current (voltage drop = I^2 R). Higher voltages cause other issues such as dielectric breakdown. Deep ocean cables are actually pretty thin, about as thick as a garden hose, and I doubt you could easily pass more than 15kV. You also have to account for ground voltage shift between the continents which may be as high as 1kV and depends on the weather.
I don't think it is. It's just a counter to your implication that 'only diehards' take this position.

Why should the US not have many fewer people and why couldn't that be better? There's nothing magical about 315 million people. A much smaller population would be better for ecosystems, global warming, etc. I'd demand the proviso that the population shouldn't be decimated overnight and that the age distribution can't be too skewed (too many youth or too many old). But barring that, I don't see why some lower population (even tenfold fewer) couldn't be "better".

It's not every citizen (~23M) but rather per household (~10M) that would use the system. Not everyone is online or choose the online option so it'd be less than 10M users total but even a conservative back of a napkin estimate would show that in the after dinner hours on census night they'd have to be dealing with closer to 3M to 4M users per hour peaks.

Very badly planned. They even gloated that the 1M/hour peak the system was designed to deal with was twice what they needed and it'd all be fine even when lots of experts were pointing out that that wasn't going to cope.
