Area 51, the place where dreams (site proposals) die
Ugh. A little bit of me just died realizing that politicians are going to get even more aggressive about their marketing after the success of Obama's campaign tactics. They'll use it as a template moving forward.

Since they're the ones writing the anti-spam and anti-robo-call laws, we'll have absolutely no protection from their pursuit of marketing their messages to us.

The really sad thing is that back around 2007, Obama promised an open campaign that would use public funding - signaling that he was a different kind of candidate who didn't want the corruption of money to taint his campaign. Rather than leading the way on the high ground, the whole process is being dragged rather deeply through the mud.
There is something wrong with your jet/mud/arm analogy, because it doesn't translate the real life results. The size, location, mobility, etc. make a difference.

Also, these toilets come with a warm air dryer as well.

I also saw them for the first time at Google, and then I bought one for home. It saves a ton of waste and you'll be and feel cleaner afterwards.

Granted, it does take a little more time to exit after you are done. But, if people were really in a hurry why would they keep a magazine/book by the toilet?

I agree, while it's not an accurate representation of the majority of startups, it is a pretty accurate representation of some of the wanteprenuers that are "business people" with some money that no nothing about programming and want to get into Startup Life (tm)
This is a really interesting point - I think the question will really come down to how well campaigns / businesses can measure the impact of their marketing. If your messages/posts aren't driving donations or purchases (or hurt the long term usefulness of the person you're marketing to), then you won't run them.

The problem is that today most marketing is blind - completely unlinkedin from the impact it causes. I'm counting on technology / big data / analytics to change that.
Yes. You should wait for CM 10.1 if you want Android 4.2.

Personally, I only use Cyanogen as a last resort on phones that no longer receive updates or that have poor stock ROMs (Samsung Captivate, for example). I have no desire to install CM on my perfectly functional and supported Nexus 7.
The problem with the CM project is most of the devices it tries to support are not open source. What I mean is that the drivers for the radio, GPU, audio, etc. chips are not available in source form like Android itself (via AOSP). In order to compile a ROM for any device, the developers have to rely on binary blobs ripped from an official update or a different device. Unfortunately, that means bad support for devices that don't get updates by their manufacturer.

Case in point - Samsung Galaxy S2. The S2 had an official ICS ROM release by Samsung and devs managed to get a stable build of CM9 running on it. However, as of now there is no official JB update for the S2 and CM 10 is far from stable on that device. There are problems with the Yamaha sound chip (low volume), problems with the graphics chip (Hardware Composer), USB, TV-out, etc.

I am really hopeful about the new Nexus devices though. The Nexus 10 is the most OSS friendly Android device I've seen - everything except the GPU driver is available as open source.
Warning your users about a vulnerability
It should also have a vacuum breaker, which is required by code. Massachusetts plumbing code is typical:

>Approved backflow preventers or vacuum breakers shall be installed with any plumbing fixture or equipment, the potable water supply outlet of which may be submerged and which cannot be protected by a minimum air gap.
I don't have the source handy, but I remember there were at least two very attractive features that started the trend of "advanced" toilets in Japan:

1) A seat heater: Bathrooms used to be unheated so without this it would be very cold in the winter. Adding a heated seated was much cheaper than adding a room heater.
2) An artificial sound to overlay embarrassing farting sounds: Without this feature, it was common for Japanese women to constantly use the flush in order to create a louder sound. This was obviously a huge waste water.

Once the ground was laid, it was natural to extend the number of features.
See, my perspective is completely skewed. I don’t even know what a custom built home is. I don’t have a house nor any plans to get one but my dad (a civil engineer, usually planning water supply systems) drew up all the plans for my parents’ house and my parents (including the extended family plus friends) really did nearly everything by themselves, and that includes picking out all the interior. Everything is custom about that house. In that context someone telling you which toilet to get is nonsense.
Aaaaand, this is a huge reason why the whole "experiment" is utterly invalid. Without making use of experienced devs for each language, and perhaps a statistically significant number of samples for each language, the amount you can trust any of this data is precisely zero.
The closest thing is dodgy energy accounting -- making high energy-embodied or pollution-intensive products in places outside the regime, like Chinese steel mills.

Hmm, I thought it was more like 10s to 100s of microseconds of latency for a SSD.

I've seen estimates that Google fiber latency (when plugged in, to the nearest Google datacenter) could be anywhere from microseconds to 10s of milliseconds, but I don't have any reliable sources and I don't have any expertise here myself.

I'm hoping that someone who does know might chime in?

While I agree that Americans are especially prude, its not like these toilets are noticeable more common in Europe. Of course the French have their bidet...
Totally serious. You picked beating, which is THE classic side effect operation, and you had no idea what was going on? If so, just refresh your memory on what beating the egg actually does (spoiler: people don't beat eggs because they are angry at them):

Flushable wet wipes changed my bathroom life. I now don't even consider doing my business without them. Way cheaper than installing a bidet, and I would argue it's more effective, too.
I imagine it's to do with price, at least for public toilets.

Here in the UK , we can't have nice things because someone will just take the liberty of smashing it to pieces for you.

For what I have heard about places like Tokyo; you have vending machines for just about all of your needs, fancy toilets and video game arcades have actual chairs to sit on while you play the machines.

None of these things would last 5 minutes in the UK.
While my mom was in home hospice, someone purchased these for us to help her:

After she passed, my Dad just threw them in the guest bathroom. Using both paper and these (preferred order is up to the user) seems to fit the bill for just about any, uh, circumstance, and I've had numerous people make positive comments on it which is strange in and of itself.

At first I thought it was a bit wasteful, but I think many times you can get by with less total paper. YTPMV.

I would like to point out that women use washlets when they urinate and they are, especially with a built-in dryer, infinitely better than toilet paper alone.

Further, they shouldn't require much precision as the area we are talking about isn't all that large. Of course, until you get to the high end models, you generally don't get position adjustment or oscillating cleansing.

Maybe the Google ones you used were just poor? The ones I used in Japan ranged from excellent to ok.
Its not just Japan. These toilets are what you find in most middle class homes in India too!

Pervasive Wireless Means Persistent Frustrations
My wife dragged me to an appliance shop in the Mission (SF) and they had a toilet like this in their bathroom. At first I was shocked and appalled at how forceful the stream of water was - especially as I had it on the 'low' setting. Then I became aware of how long it was spraying because after 30 seconds I had to turn it off. With the combination of these two (and the heated dryer), I didn't have any problems.

What i'm saying is the customer usually asks for a white toilet that looks like X. The builder says, "Manufacturer Y has something like that. Does this look good?" knowing that manufacturer Y works with his suppliers who will have the exact product at the exact time that they need it.

Sure you can go to a builder and say I want this, this, this, and this, but be ready to pay out the nose for someone to do all the work to make sure they show up correctly and at the appropriate time.
I quickly ran the code on J and got ratios of lines:0.5, characters: 0.74, tokens:0.5, over 432 comparisons IE J is about half the length of Mathematica code.

APL, has ratios of between 1 and 2 (IE a little longer than Mathematica, but over only 32 comparisons which is too few to be reliable).

Julia was also asked about, but there are only 9 comparisons which is certainly too few to be meaningful.
I hope the irony isn't lost on you that this means you did not pick the toilet in your house, just like you found it hard to imagine other people doing!
The BLS (see http://www.bls.gov/oes/current/oes_nat.htm ) says the median hourly wage in May 2011 is $16.57 across all occupations (mean hourly is $21.74). That fact should help put things in better perspective.

Assuming $20/hr as a good ballpark figure for most working people, that would mean working 12500 hours to gross $250000 in a year. Clearly one person couldn't possibly do all that; so in a double-income household that's really only 6250 hours each. That's a 17 hour workday, taking no days off. Unless they really insist on having a day off every so often, in which case that'll be 20 hours a workday.

In all seriousness, if it's a power-couple pulling in $250k gross annually, that's somewhere in the neighborhood of $60/hr for each of their jobs, which is about three times the median overall, and more than what the "median" scientist or engineer makes (per BLS stats). According to BLS, median wages are over $50/hr for these occupations: doctors, psychiatrists, Chief Executives, dentists, Petroleum Engineers, senior managers, judges, magistrates, Air Traffic Controllers, pharmacists, lawyers, and physicists. The median for "Computer and Mathematical Occupations" overall is about $36/hr.

So who are among the roughly $20/hr crowd? They would include (within median wages $18 thru $22): Heavy and Tractor-Trailer Truck Drivers, Museum Technicians and Conservators, Credit Counselors, Statistical Assistants, Mental Health Counselors, Machinists, Carpenters, Surgical Technologists, Licensed Practical and Licensed Vocational Nurses, Sheet Metal Workers, Interpreters and Translators, Medical Equipment Repairers, Firefighters, and Structural Iron/Steel Workers, etc. These occupations sound like middle-class lifestyles to me.

Assuming a two-income household, each working 1800 hours at $20/hr, the annual household income is $72000 gross (hopefully with benefits). And there you go, a fairly objective definition of a middle-class family, of about $70k a year.

To anyone blessed with over $200k/yr, just consider you're really at a place where you could buy - lock, stock, and barrel! - the sort of residence the $70k/yr live in every few years. Really! Just cut back on your extravagances, and you could own a fine middle-class home outright in five years or less. The $70k/yr folks may take decades to achieve the same.

This is not to say you shouldn't enjoy, or that you haven't earned, your success - nothing of the sort. It's just that nobody really believes that someone who has the means to own a nice home in rather short time is middle-class too.
These toilets are a pleasure to use. But I think the main reason many people don't consider them is that you need a nearby electrical socket or have a big dumb cable on your bathroom floor. The article quotes $500 to have a GFCI socket installed but that in unrealistically low in some parts of the country. > $1000 is a decent investment, especially if you consider your bunghole reasonably clean today.
We are going to be adding e-mail sign on shortly.
And if you want a warmer, you'll need a GFCI outlet installed next to the toilet, which most US homes do not have.

Am I the only one here who would install it myself?

>Of course the French have their bidet...

I'm French- there's a bidet at my grandparents' house which is never used, and there used to be one at my parents' house but they removed it when they remodeled the bathroom because they never used it (it was there when they bought the house).

I've only ever used a bidet to wash my feet (or as kids, we would put our swimsuits in it to dry). I'm not even sure what its original purpose is.

I agree with David's general thesis and the items on the list except for the App Stores.

Naturally government-oriented influences like the patent system and regulations are monopolistic. Net neutrality is monopolistic because the backbone infrastructure is in the hands of a relative few number of infrastructure owners. Often, where you live determines the connection to your house and that's a monopoly often enforced by municipal contracts.

App Stores are the only item on his list that are not quite monopolistic in nature. As such, new competitors can come along at any time to unseat App Stores that are failing to provide enough value to consumers.
MacOS X people might want to investigate Eastgate Systems Tinderbox. Can handle the navigation links for huge ad-hoc Web sites using a local template then generate the Web pages.

There are also large, flexible applications such as jekyl that can generate static Web sites.
From what I read on the internet 25-40% of people out there seem to stand up to wipe.. and I have to believe that's largely due to people never discussing how they use the restroom.

Unless your site is a differentiator for your business, I wouldn't go hog-wild on it. I'd start by looking at something like ThemeForest, where you can browse around, see if you find something you like, and buy it for not-a-lot-of-money.

Those are terrible, terrible metrics. The first question I'd be asking myself if, "With these numbers, why did we let the test keep going so long (3000 clicks)?" It seems like it would've been clear about 1000 impressions that your CTR was awful. That's a huge indicator that something is amiss.

These are the kind of numbers that imply that "the keywords that your ad was actually shown for" were not in line with "the keywords you thought your ad would get shown for".

Have you looked at the keywords that actually triggered your ad?

I just finished watching MIT 6.00SC for the hell of it. It was really sad experience.

Of course, prof. Guttag is really a big-shot and seems like no one could say anything, but I cannot even properly describe how much worse it was than CS61A by Brian Harvey.

It is not just Python, it is ugly Python, boring Python, without any hint of elegance it could be. No list-set-dict comprehensions, which is what makes Python interesting, very few slicing examples and one or two use of yield.

I must say that usage of classes was reasonable - only when there were even a small advantage to structure the code this way, but it is just boring stuff.

Each lecture of CS61 keeps you alert and awake, and curious, time passes unnoticed, and you almost feel how a new connections growing in your brain,) while in 6.00CS you're forcing yourself to to stay alert, almost yawning.

So, if one is engaged in self-education just do CS61A and old 6.001 classic videos. After you can skim trough all those mainstream Python-based courses very quickly with great ease. I can do 4-5 lectures per day.)
If you just want to rotate point clouds, it might be hard to do better than taking apart and studying a project that does that (like this one).

I am on rMBP and it hardlocked Chrome after I navigated towards the sun and clicked the information button about the sun. Worked fine until then, really cool.
I must disagree -- in my experience, the jet/mud/arm analogy translates precisely into real life results.

Also, should you find an additional paper pass to be necessary, you'll find it complicated by the fact that the area to be wiped is now wet. Toilet paper notoriously doesn't hold up well when soaking wet.
Unsurprisingly, at least to those who follow craft brewing, "contract brewing" is one of the ways to start a brewing business at relatively lower risk (with the other being "brew pubs"). (This is according to various books, such as "Brewing Up a Business" (by Sam Calagione of Dogfish Head Brewery) and "Beer School" (by Steve Hindy and Tom Potter of Brooklyn Brewery), as well as conversations with contract brewers.)

To the "beer geeks", there's seemingly an ongoing debate whether a contract brewery is a "real" brewery. But that's another discussion...
