> Not to mention that Bitcoin is explicitly anti-environmentalist: it's built on vast amounts of wasted electricity.

That like saying Tesla's are anti-environmentalist, it's built to waste vast amounts electricity.

It's quite literally non-sense. Point at any other nations currency that consumes less energy than Bitcoin; you think printing bills and minting coins doesn't use energy? You think moving giants piles of cash around in big trucks between banks doesn't use energy? You think banks and guards and trucking don't use energy?

Bitcoin is the pro-environmentalist approach, it uses far less energy than a typical currency does.
All right, everything turned out better than expected, then. :)
The US profited enormous from Europe falling to pieces. Re-building Europe swept in money into US kofers for many, many years and is in fact still ongoing, albeit to a very small extend.

Consequently thinking your thoughts ahead will inevitably results in either WWIII or massive poverty coming all over us the moment the first asks value for money and demands his money back. In fact we are already there as we are relying on fiat money rather than backing by "real" goods.
It can be done without macros, but any such solution (fexprs included) would be much worse than a macro-based one. Much more complicated, much less efficient, etc.
Just purchased and played several times. Very solid gameplay, nice retro graphics, fun music. Congratulations.

I was kind of hoping for some power-ups, like a faster shot rate or scattershot. Those might be present, and I just didn't get to them yet, only made it to stage 3-x on first attempts. I also wish the stages had more variation, might feel too repetitive after a while – though that might happen later also.

Anyway, for $0.99, I'm definitely not complaining. It's a fun game and definitely an example of what I'm looking for. I'd personally be willing to pay more, in the $4.99 range, for a game like this, especially if it had some the variation features I mentioned above – but I might be unusual.
The rules probably aren't the same as they are in Back to the Future.
I understand your point that modern vehicles are relatively safe, but after seeing the result of a semi truck taking out a pickup truck on the Interstate yesterday I am seriously considering my choice to drive a compact vehicle. I assume larger vehicles have larger/longer crumple zones compared to compact vehicles and that higher vehicles have less chance of going under other vehicles? Of course it's zero sum if everyone drives larger vehicles but I can't force the local authorities to invest in better public transportation so I don't even need to drive to work.

> The general quality of discourse on any thread seems to drop hugely whenever politics comes up.

Yeah, politics is the mindkiller.[0]

Dan Kahan's research could lead to some interesting suggestions about why this might be.[1] There are many questions we answer dispassionately about facts, but then there's this other series of questions about the world, where we really don't answer with reference to specific knowledge. They seem primarily to serve as litmus tests for measuring group identity.

As it happens, contradicting someone who is really just talking about their identity just makes everyone upset.

Certainly conversations can change some people's minds on some political topics[2]. I've had a few rare 'conversion' experiences when talking with friends. But it's usually in really specific situations with certain approaches to open discussion that are just really hard, sometimes it takes multiple discussions, none of which seem that monumental, but have a cumulative effect. Both conversants have to rely on a lot of care and patience. All of that is made much more difficult by the impersonal and ephemeral nature of conversations on the internet.

Ray Bradbury, the Art of Fiction No. 203
The first differentiator will be price: I would like to figure out a way to offer this to patients without charging for the app or turning the patients into a product. As a tool to help people help themselves, I would like to lower barriers to entry as much as possible; which is why I'm exploring the possibility of pursuing this idea as a non-profit. Other apps that I have found are either paid apps or free with in-app purchases (e.g. in-app purchase to keep your mood log private; I wonder what privacy is like in an app whose default state is public posting).

There are many more mood trackers than apps that allow you to track one dimension such as mood and not both symptoms and potential contributing factors, but as you point out there are some apps doing this already. Existing apps that track both symptoms and mood have two challenges:

1. Staying motivated to continue to log data daily as a patient goes through an evaluation is difficult if record keeping is done with pencil+paper or an app.

2. Apps that track more than mood have a more complicated UX to handle input across a variety of dimensions.

Apps like mySymptoms do make self-evaluation and data collection easier because the patient will usually have their phone with them; but this is still a chore. mySymptoms was designed to track symptoms for Irritable Bowel Syndrome and the UX reflects the motivation level of that user group.

Instead of a log keeping app, I want to make an app that will act like a personal lab assistant guiding the patient through their study of 1. Here is how I am trying to make this process of record keeping easier:[EDIT: fixed line breaks]

1. A UI/UX that allows data entry with as few touches as possible: each datapoint should be able to be entered with a single touch or gesture (voice interaction would be useful too, but one step at a time).

2. Present the user with one question from the lab assistant at a time instead of providing a daily grid to update.

3. Don't wait for user action, but prompt the user to interact with the app. Timing of prompts can be triggered by learned timing of user interaction with the app, desired medication/eating schedule, and sensor input to ask questions at the right time (some users my respond to prompts better while on the move while others when at home).

You can get inflation in two ways.

One way: people and firms are expending more money that the economy can digest. If a government wanted to compensate this, could raise taxes or, ironically, retiring money from the system emitting debt.

The other way: the money that people is expending is the same but the economy, for some reason, shrink. That would be a supply shock. That is what happened in the 70's with the oil cartel.

Ummm... SFO landlords have huge demands for their apartments. It's pretty common for them to demand you pay for them to do a credit check just to apply to rent their apartment. So I seriously doubt there are many that decide "you're cool, I'll rent to you".

Of course, you can always find an idiot, but I've never heard of anyone who rents without a credit check.

File under the "it's expensive to be poor".

One observation from growing up poor, around lots of other poor people (but not something I noticed in people who I'd classify as falling into "true" poverty) is the crazy amount of money that gets spent on absolute bullshit in some desperate attempt to make the life-suck less awful.

I could list some examples, but the stereotype of poor people with expensive shoes or lots of cheap jewelry or whatever is often partially true.

Canada doesn't have an estate tax, but it has something largely equivalent: http://www.investopedia.com/articles/retirement/08/estate-pl...

Sweden only very recently (2005) repealed its inheritance tax after centuries of having one. So the current inequity levels in sweden occurred under inheritance tax. Prior to 2005 the inheritance tax rate in sweden was 60%, higher than the estate tax in the US. And vastly more people hit the tax in sweden as the exemption was a mere $8600 USD.

So if anything Sweden is evidence that a stiff estate/inheritance tax helps prevent inequity. We'll see if that changes.
"Before that I used airbnb.com to find a place and there are a good number that are under $1000 a month outside downtown SF. She could've done something similar."

OK...I just did. I found nothing less than $1500 a month, even expanding my search radius to include Marin, the entire east bay, and all of South San Francisco. The average nightly is $179.

Of all the things in her post that you could choose be self-righteous about, her rent is the one that makes the least sense. Her budget was realistic. She wasn't living in luxury.

A replication slot can be used by defining it in the pghoard.json configuration. However, the slot needs to be created (and removed after no longer needed, important!) manually. We've been planning to add more automatic replication slot management to PGHoard.

I can't speak for edtechdev, but it certainly has been effective for me. I've dropped about 20kg since christmas through a combination of diet changes and doing HIIT on an exercise bike 2 - 3 times a week. Obviously the diet has the most to do with the weight loss, but over the past 4 months I've gone from barely being able to do 30 seconds high intensity / 1:30m low over 20 minutes(total time), to being able to do 1 min high 1 min low at a higher resistance for around 40 minutes.

I'm not American so I'm slightly confused by the terminology here. In the article it says she was renting a one bedroom place and looking for a roommate. I've frequently assumed that when Americans say 'roommate' they actually mean somebody they share a house with (what we would call flatmate or housemate in the uk), rather than somebody they share a bedroom with. But in this case it sounds like she was trying to find somebody to actually sleep in the same bedroom, since the place only had one bedroom.

In your comment you say you have 'roommates'. So to be clear, you saying that you share a bedroom with at least two other people? And you consider this normal for an adult in a developed country?

Is this really the situation in SV now? People who are "DevOps Consultants" have to share bedrooms with random strangers just to afford to live?

For the people posting "sample size was only 25" and related comments, the below is from the PLOS abstract. p values <0.05 indicate that the results are not due to just chance. The p values of their results are quite low for the test group, but large for the control group. This indicates the results are statistically significant.

"Results

Peak oxygen uptake increased after training by 19% in both groups (SIT: 32±7 to 38±8; MICT: 34±6 to 40±8ml/kg/min; p<0.001 for both). Insulin sensitivity index (CSI), determined by intravenous glucose tolerance tests performed before and 72 hours after training, increased similarly after SIT (4.9±2.5 to 7.5±4.7, p = 0.002) and MICT (5.0±3.3 to 6.7±5.0 x 10−4 min-1 [μU/mL]-1, p = 0.013) (p<0.05). Skeletal muscle mitochondrial content also increased similarly after SIT and MICT, as primarily reflected by the maximal activity of citrate synthase (CS; P<0.001). The corresponding changes in the control group were small for VO2peak (p = 0.99), CSI (p = 0.63) and CS (p = 0.97)."

I don't think this is true at all. My experience of years of sprinting has given zero such injuries, and usually it's first thing in the morning, and the only warm up I have is walking to the car, driving to the track, walking from the car to the track.

I've also never did more than a few incremental warm up sets before lifting (relatively heavy) and have never had a pull or a tear.

Warming up is one of those seemingly agreed upon myths in which the scientific evidence is minimal and typically shows the contrary.

edit: for example: http://healthland.time.com/2013/04/08/why-stretching-may-not...

And to add to this, it doesn't even make sense from an evolutionary standpoint. Having a physiology that requires warming up muscles before needing to escape a threat would be weeded out pretty quickly. A predator attacking a camp of humans, for instance, would allow those that can run fast without their "muscles pulling or tearing" to escape leaving those without such an advantage laying about groaning in pain while the predator gets their fill.

Yes, the subsidies used to factor into that bigtime. The hardware was sold at a loss, in the expectation of making a profit on controllers/accessories, games, subscriptions, etc. That's no longer the case nowadays - the XB1 and PS4 are both being sold at a profit (or at least not a loss).

I think the trend away from specialty processors with speciality GPUs attached like the Xenon [note: different from Xeon] in the XB360 and the Cell in the PS3, to commodity Jaguar x86 APUs with onboard iGPUs is a big reason behind that. Honestly the XBone is really no different than going out and building yourself a mITX PC on the FM2+ socket, for Linux purposes. Nowadays you're better off with something like the Raspberry Pi for intro-to-computing, although I am a big fan of the ECS Liva series myself.

The Cell is actually a really amazing processor in a lot of ways. It's really more of a SMP system with a ring-topology interconnect than a traditional SMT processor. You have to specifically build your design around it, but if you do so it's really fast. It's actually only recently that general-purpose x86 has caught up enough that it's feasible to emulate it. It would have been a very desirable piece of hardware for HPC, if you had stuff tailored to that architecture.

This is why so many people can't work their way out of it. $300 sneakers to look cool in the ghetto or a community college class? A $600 iphone or a laptop for your kids? A new tat or new clothes for your kids? When I lived in a 'up and coming' urban neighborhood, my unemployed/welfare neighbors had nicer shoes and phones than I did. But they partied until 2 or 3 while I had to go to bed early for work.

Part of the problem of being poor is lack of self-control and lack of planning and how that all culminates into a endless party/bling lifestyle. This is why education is seen as the solution to being poor, not necessarily a lifetime of handouts. Income distribution hits the laws of diminishing returns pretty fast. Some people, unfortunately, can't accept this for political reasons, hence all my drive-by downvotes.
The New York Times had an article a while back about how conspicuous consumption habits vary by region, and only sometimes by income. In out-and-about and status-conscious New York City, rich and poor alike spend a disproportionate amount of income on shoes in watches.

An interesting takeaway was that in Cleveland, conspicuous consumption of premium sodas and cigarettes were far higher than anywhere in the nation. I suppose when you're really that poor, you'll do - or buy - anything to feel that you aren't.
