Sorry, you're right. I meant that you are using ethnicity as a proxy for geographic location. For something as broad as "Arab", it's not predictive - just like "Christian" is not predictive for figuring out who might kill an abortion doctor, or "Japanese ancestry" is not predictive for who will sabotage US military installations on the territory of Hawaii. (Hint: none of them; and the US has apologized for the internment camps.)

It's predictive in the way that saying African Americans tend to get worse grades in school. The primary correlation is with poverty - African Americans tend to be poorer than average - not ethnicity.

So, even if you think ethnicity is important, how do you know that other characteristics aren't even more important? Look at the VAM for schools to see how difficult it is to be predictive even when you have lots of data points.

> "Not necessarily"

That's approaching a movie plot scenario. Either you have evidence or you don't. Hand-waving counter-examples is not evidence.

> "I said racial profiling is OK at airports and for catching the other kinds of terrorists (and for which such programs as TSA started anyway)"

Racial profiling is illegal in the US. Therefore you have no US evidence that it would be effective. How would you even measure effectiveness ? Fewer hijackings every year? Fewer bombings?

For that matter, why do you keep picking race as the key predictive feature? Why aren't you arguing for sex screening? Look at all the male terrorists. Why aren't you proposing that women should automatically be allowed to use the TSA Pre-Check lanes, so the TSA can put more resources on searching the men? Once that's done, then argue for screening by race, which we know is less effective.

> "They could be said to be terrorists too. I didn't suggest anything about them though"

I know you didn't. That's because you're picking the lazy solution for the easy problem that doesn't really exist.

Think of it this way. There are 10M people of ethnic group X in a country. Of them are 10 who plan to carry out a terrorist action.

If we put racial screening in place, we can catch 2 of them. On the other hand, there's a 1-in-a-million chance that the added frustration, humiliation, and resentment will cause someone to snap, and decide to carry out a terrorist action.

Congratulations, you now have 10 new terrorists to replace the 2 you caught.

Yes, this is also approaching a movie plot scenario. But since that's all you really have to back your views, then that's what I'll use too.
> told the IRS that the money was made illegally and nothing happened

Is there a checkbox on US tax forms for "illegally earned money"? Or are you expected to put that in a free-text field?
Slightly related, they have housing cooperative in Germany, especially the East. You can own a share, and get much reduced rent in return, in any of the cooperatives apartments and houses in the city. Depending on how well they do, they might also pay a dividend, but mostly the owners of the cooperative are also the renters, so generally they rather keep the rent down than make a profit.

I know old people who `paid' for their shares by working on building sites for these very houses in the 50s and 60s.

As a resident of Somerville, I definitely want narrow streets and a lack of parking. I'm really tired of drivers almost running me over on the way to work on my bike because they think they have exclusive rights and high speed limits on any road with at least two lanes.

Pedestrians looking in the first-floor windows can be solved by putting shops on the first floor.

I'm also strongly in favor of the forever-proposed Green Line Extension into Somerville and Medford. I know it will increase rents while I'm still a renter, and I know it's gentrifying some neighborhoods at the moment, but by God it has to happen! It's downright shameful the way a Somerville resident has to walk or drive to Davis, Porter, or Charlestown to get to a T stop, and those will only travel through selected arteries that don't necessarily include most of our workplaces.

Heck, we could redraw the bus-lines too, so maybe I could get a bus from Somerville through to the main artery roads of Cambridge. When the weather sucks too much to bike, at the moment, my commute doubles, because instead of a 15-minute bike ride, I have to walk 10 minutes to the Red Line at Porter, take the train for five minutes to Central, and then walk another 10 minutes to work from there -- a circuitous route that just happens to go through the Mass Ave-focused Red Line we actually have transit for.
Most 2012 cars are not worth more than a third of the original MSRP, especially if you're looking at typical trade-in value.

If I were in the market for a car right now I'd be looking for about a 2008 model year. All the significant depreciation has already been realized and you can find some real values in good condition with a lot of life left if you shop around a bit.

It's just a statistic. There are lots you can look at. This one is interesting specifically because it hasn't happened in 4my. The earth will be fine, life will continue.

The more specialized something is, the more it's at risk for exceeding tolerance. Costal housing is good example. It's built to withstand perhaps 100mph winds, beyond that roofs come off.

The built in mitigation is pretty slow, so there will be perhaps a couple hundred years of rebuilding stuff. Sea walls, levees, more weather resistance.

As I said, I have not. (In the US, I've only been to Silicon Valley and New York City.) So I had to rely on on the street view pictures.

And, yes, I can very well believe that it's the 16th most densely populated city in the US. The US just doesn't have many proper cities.

i don't think this company is suggesting anything of that kind, because this myth has been perpetuated since the start of retail financial markets, and possibly both the brokerages and other retail investors are to blame for this.

everyone in this thread here seems to have the common sense to say "don't try to compete in the same strategies as the HFT specialists". that's absolutely true.

but then this idea that financial markets cannot be anything else other than a HFT's playground doesn't seem to go away, even in this thread. that's not a fair assessment.

if you are a retail investor, if you pick a portfolio allocation appropriate to your risk appetite, if you pick a reallocation and reinvestment policy that you can get a good handle on, and you stick to it without fail, then you are half of the way to what pensions/insurances/savings plans implement for you, except now you don't pay fees, and you don't have to wait 20 years for the investment to "mature". in fact, because retail fees are so high, retail investors are better off using a minimal rebalancing policy: trading less, tweaking less, getting less fidgety about their trades - and that is a good thing. trading less and getting better returns usually comes together.

if you are happy with more risk, and you take controlled bets with options structures going out several weeks or a few months, you can get away with some good wins and a hopefully fewer losses and may still come out ok even after spreads/fees.

if you try to compete with HFTs on the sub second horizon without any of the equipment/services that the HFTs pay for, then you will lose. don't do that, that space is not for you.
There's almost no commerce in Somerville (compared to other cities). It's residential next to residential next to residential. As someone pointed out, it is among the most densely populated cities in the US, and significantly more so than Cambridge, because there's nothing else BUT residential properties. So even though the buildings aren't that large, it's really dense.

A "smart" doorbell could automatically pause your DVR, connect you to a one-way camera/mic system, and give you the option of turning on the two-way intercom, all without having to walk to the door. Very useful if you have a large or poorly laid out house where anything is far away from the front door. You could also set it up to send an SMS when a package is delivered and the delivery person rings the bell.

A conceivable smart bed would integrate with your sleep tracker, calendar, smart lights, and audio system to measure your sleep and wake you up at the optimum time.

But all of this needs to be done (and could be done) with strong privacy protections and network-level isolation.

At present, I can't imagine ever wanting a "smart" blender. I've got a 15-year old Vitamix that still powers through my daily smoothies with gusto. I had to replace it's blade assembly, once. I can't imagine a smart blender remaining functional for anywhere near that long.

However, I've also been hilariously wrong about tech before. For example, in the late 90's I heard about wireless network research. I didn't get it. What's so hard about plugging in a damned computer to ethernet? Now I have multiple wifi devices and not one of them is a desktop computer.

The payoff for smart devices might be hard for us to imagine right now. The risks, on the other hand, are readily apparent. For example, a smart thermostat could be hacked into and your house's temperature set to something undesirable. For example, if it's winter and you're in a cold climate, turning the heat off completely while you're away could cause your pipes to burst. It's therefore important that we keep security and reliability in mind when making these devices, so that what we might gain isn't offset by a certain loss in reliability. Continuing with the smart thermostat as an example, it should probably not be possible to set it below 0 C unless you have physical access to the device, and it should probably raise some very annoying warnings even then.

It's also important that "smart" devices remain functional for a time period comparable to their more traditional counterparts. We tolerate obscene obsolescence rates in cell phones, mainly because their capabilities are expanding so rapidly. People don't want to buy a new thermostat every couple of years. In fact, most people would expect a thermostat to last a couple of decades, even if it's "smart". That means designing them to last with standards that will be supported for a long time.

In short, we might not see the upside to "smart" appliances just yet, but they could materialize. It is, however, important to insist on "smart" appliances that aren't too "dumb", nor should we accept appliances with short lives as a result of being "smart".

The smart I would LIKE would be a robust high temperature rated fanless immersion-rated VFD driving a direct connected 3 phase fanless immersion-rated motor with programmable (sane) rotation ramp up rates and torque monitoring via current sensors on each phase to deal intelligently and safely with jams and such, and tie in safety switches so people can't stick their hand in there without the VFD noticing and cutting out at the VFD level. Also if you're monitoring torque it can ramp down once the margarita is pulverized saving electricity. Probably there is a real world optimum rotation cycle that uses the least KWH to mix a margarita and a smart VFD could follow and adapt itself to that goal. So faster, quieter, safer, longer lasting, real-green as opposed to greenwashing sounds smart to me. I suspect I could pull that off for a kilobuck. That is not entirely out of line BTW for high end cooking gear.

The smart I will GET is a buggy bad UX app controlled blender that only runs on android 2.2 phones and no newer phone OS AND requires the mfgr to keep the big brother server in china online or else its just an abstract sculpture brick on my counter. It'll monitor every use to sell to corporations and it'll post on my behalf on facebook primarily to embarrass me. It'll be less reliable and shorter lived than a purely mechanical blender, and it'll probably require a foul and obnoxious financialization scheme where I have to subscribe to a monthly "blender service" to use it at all. An hour with the diagonal cutters and my soldering iron will rip out the "smart" thus improving my user experience, or maybe I'll have to commit some DMCA violations. Commit some DMCA violations to mix a margarita...

Its about the same level or intensity of hardware and tech in each case, its just the business model of "smart" right now is much more the latter than the former and therefore "smart" always suxs and the public is starting to figure that out. Which on a meta level sucks because if I had infinite spare time I am completely capable of making and selling the former "smart" blender, but the disaster of the "latter" smart blender will poison the marketplace such that people would run in terror away from my (former-type) smart blender.
This is very human-centric point of view. How many species will be lost forever as a direct cause of this event ? Sure, it happens all the time, but typically over a much longer period meaning other species can evolve to fill the gaps. There is no time for evolution to work over the 200 years this last change happened.

Another thing to consider is that the less diversity exists the harder it is for life to continue.

The sooner the better. According to the most realistic climate models, the point of no return for ~2 degree global average warming is already over. We don't have a good idea at what point truly catastrophic damage is going to occur (by which I mainly mean something like a Siberian clathrate gun that could hypothetically drastically warm the climate within a human lifetime). Continuing the current path of CO2 increase, every 10 years increases the risk for a runaway warming process. What's worse is that our models aren't good enough to say with certainty how high this risk is (or that it doesn't exist). So really, the time we live in now is what counts and every little bit we do, helps.

Silicon Valley – summarized
That's my way of thinking about it too. At any rate getting nearly 200 independent nation states to agree on anything when they all individually benefit by flouting the rules - that's madness. We'll burn oil and coal and gas until it doesn't make economic sense. I very much doubt politics will change the outcome. Technology will hopefully save us from ourselves on that front.

A bigger problem is positive feedback loops. Melting ice means more dark water to absorb sunlight, and more melting. Melting permafrost releases CO2 and Methane and causes more warming. And somewhere around ~5 degrees warming the frozen methane on the ocean floor will bubble up and cause the mother of all feedback cycles. We'd be in for about 10 degrees warming and a mass extinction that would wipe out 90% or more of all species on Earth. From what I've seen of global warming predictions we won't get there - but I'm mentioning this because at some point warming temperatures doesn't just mean major changes and flooding our cities - at some point it means a terrible calamity like the Earth has only occasionally seen.

In the general case, what you do is you take a wideband excitation - like a buffer of random samples - and use it as the initial value for a system with a lumpy frequency response. In this case the frequency response is very simple but more complex IIR filters work too.

As the article says this is a good analogue for how a lot of musical instruments work. A string is a resonator, and plucking it gives it a wideband excitation.

> Terraform isn't really doing anything that snazzy compared to Cloudformation

I'd disagree with that. Just take a look at the Terraform Changelog[1] for some of the latest & greatest.

For example, the concept of "Data sources" is pretty cool. Basically, you can reference pre-existing data, potentially do rich queries against it, and get a read-only value back. For example, you can use a Data source to find the latest AMI for a given search string.[2]

CloudFormation has a concept of Custom Resources[3] which could achieve similar functionality, but not without a lot of hassle.

Terraform has also been building up a rich language of interpolation functions [4] that can be used for string replacement, hash generation, and even arithmetic.

There's a lot more, too. I think it goes well beyond "cloud-agnostic."

I once fixed the alternator pulley on my 1984 VW Rabbit in the parking lot of a gas station in the middle of nowhere in Wyoming using nothing but JB Weld, zip ties, and a piece of scrap metal I found and shaped into a replacement Woodruff key.

There's definitely something to be said for the maintainability of a vehicle where a small tool box worth of tools is enough to fix 90% of all possible problems.
I still want a serial hybrid with 4 motors.

The motors wouldn't have to be unsprung weight. They could be inboard, as on the Tesla cars but in pairs. They could be inboard, tipping as needed to eliminate 1 joint per wheel. They could be out at the wheel, affixed to the body, missing the top and bottom to allow the wheel to move around them -- the car effectively being a mag-lev inside centerless wheels.

I want to not have sloppy differentials. Power to each side of the vehicle should be adjusted according to the steering input.

I don't need a battery. Give me a supercapacitor that is just big enough to handle regenerative breaking from 80 MPH to a stop, followed by running the engine while waiting for a drawbridge or freight train.

It's not about fuel economy. It's about acceleration, including 4-wheel fully independent anti-lock acceleration. It's about never feeling the jolt of changing gears, and doing so without the wimpyness of a CVT. It's about getting all this when there is no place to charge an electric car.
