I have plenty of experience frying BBBs while trying to make LEDs blink ;) http://colorcreative.io/portfolio.html. The reason we use RPis in my place of work is due to USB peripheral support. I love the dedicated PRU in the BBB, though. It's perfect for the tight timing spec required by the WS281x LEDs :)
I presume you mean that the tech stack of modern civilization was created by 'geeks' (although that's stretching the definition quite a bit)?

Ignoring all the politicians, businessmen and artists trivializes civilizations development quite a bit.

Also, science and technology is morally and politically impartial. Note that saying increased knowledge or productivity 'is good' is again a value statement.

Yeah, I think so too but that's just my position - but this is not a mathematical truth but a political position that requires constant backing up.

The point that this requires constant backing up in adiscussion (and that that's the way it should be) and not considering people with different values and priorities as 'being wrong' was the whole point of this thread.
I think that's totally at odds with the OP's argument.

Under the OP's view, atheists aren't scary because they might be violent -- most people aren't psychopaths, that's not what social signaling is for -- but because they've chosen to chuck out a large chunk of the signaling machinery that the "middle middle class and below" have habitually relied upon.

In other words, if you've sworn off the dominant canon of ethical and social judgements, your position now suddenly requires just-in-time evaluation by the other, and that is threatening to people who don't trust themselves to reliably pull it off.
I'm going to assume you don't have a whole bunch of children, an underwater mortgage, or massive amounts of debt to service — or some other very compelling reason the following advice isn't going to be practical for you. But if you can swing it, it's vastly more fun and productive than some of the other suggestions:

Start freelancing, quit your job, and move to a cheaper country where you can survive on something like 22 hours of billable work a month (+ business development). Then spend the rest of your time working on your stuff, or whatever you want to do! No sleep deprivation is required, you can still have a life, and you don't need to rigidly structure your time. It's a decent way to keep stress levels down too which yields more productivity!

It does help if you have some savings as a buffer too!
The secret to getting up early and it not feeling like torture is going to bed early. I'm getting sleepy around 9pm, and am in bed between 9 and 9.30pm. Depending on my need for sleep I naturally wake up between 5 and 5.30am. Melatonin has initially helped me get to bed early, now it happens naturally.

The idea here is that any choice by the player yields a strategy which will not lose money, and may make money, depending on factors that are left undefined (i.e. whether or not the player and opponent choose similar numbers).

The fact that the author calls this state of affairs "a winning strategy" seems to be confusing a lot of commenters here. In practice you only benefit if your number sometimes falls between your opponent's choices, and your opponent can make the chances of that happening arbitrarily small. But suffice to say, if you actually play this game with a real opponent then the author's strategy will indeed let you win "at least as often" as choosing randomly, and possibly more often depending on how your opponent plays.
23 of the Best Ralph Waldo Emerson Quotes
Well, kinda depends. Right now, because of some crazy traveling between DC and China, I've managed to mess up my sleeping schedule a bit.

Usually, 10:30 or 11:00 (PM), especially in the summer. I also found out that I sleep in two chunks when I'm on a proper schedule. I first thought I had a problem until I read about segmented sleep [1].

It seems that there is evidence that before the industrial revolution (and ubiquitous artificial lighting), people would simply wake up in the middle of the night, read, eat or be intimate for 30 minutes and then go back to sleep.

Best Practices for Distributed Agile Teams
That's what they were already doing -- the whole problem is that it's hard to find a rigorous way to say which entity "really" created it in the sense of which portion of the value came from where. If Pixar:USA claims that the scribble on frame 33 (added by Pixar:Luxembourg) was worth $10 million, how does that show up on a accounting document that a tax authority could reject as being a sham?
I should point out that when I say it makes more sense strategically, that I mean a dollar spent lobbying for a tax break will pay off sooner than a dollar spent lobbying for a flat tax.

I don't mean strategically as in trying to get a leg up on the competition.
I've used f.lux for a while but I tend to simply not have my laptop in my bedroom anymore. I get bored more quickly to read stuff on my phone or tablet, and tend to simply go to sleep instead (as opposed to a laptop where I multi-task, chat with folks and open a gazillion browser tabs).
That's a very cynical perspective. Life isn't about money, and in my experience being a parent brings with it many enjoyable moments that could not be bought for all the money in the world.

I live in Australia where the financial support for parents is IMHO actually very good. "Family Tax Benefit" direct payments to parents are quite generous (http://www.humanservices.gov.au/customer/enablers/centrelink...) to the point that my effective income tax rate is negligible.

Quite apart from Australia's universal Medicare, supplementary private health insurance is quite reasonable (e.g., I pay $320/month for a family of five, regardless of my employment status) so I have none of the concerns about affording healthcare that I did when we lived in the US.
Be real. Make relationships with customers on first name basis. Specially when the customer is from SMB or a startup.

I have my customers on my skype/email/intercom. We have looong threads with them, discussing features and related things.
but also at the same time, the prices of these metals are very low, thus suppressing interest in developing new mines. China is playing a fine balancing game here, because if they were to highly restrict access, then prices would justify heavy investment.

They control it yet ironically cant do anything with that control or else it will sow the seeds of destruction of that control.
"...like a high-tech vending machine." Well there's your problem
You are not really "getting it" re: the effects of privilege.

It's not that going to some particular school or even a set of them (Ivy or no) matters per se. The effects of privilege exist on a continuum, and tend to accumulate over time. In that article I linked, the filmmaker had fairly extraordinary privilege via a long accumulation of access, education, peer mindset, parental support, and resources. But that's perhaps an extreme example. A lesser example: just the fact that a university student was even able to consider college as a life path is also a manifestation of privilege. For the most part, it points to an accumulation of parental and peer support over the student's life. E.g. her parents valued school and encouraged schoolwork, maybe tried to get her into a better school. She had peer support for life-paths including notions of education, career, "bettering oneself", etc. Peer support is especially interesting, as it also subsumes a lot of class issues.

Memes matter, and speaking probabilistically, kids whose peers see no paths to "success" in life can expect to have a hard time finding it themselves. We've likely all seen tales of hugely successful people who rose from modest backgrounds. That's the old story. The new one, the one we're just starting to tell, is about the enormous waste of potential from all those who didn't make it.
But Europe has more subsidies for the poor and less inequality, whereas the USA has more inequality. Cuba has much less than the rest of South America.
Did you not read the article before commenting?

> According to the Washington Post, the 19 countries that have already joined Mission Innovation will increase their annual spending on clean-energy research and development to $20 billion by 2020.

I believe odzhan was trying to show that 20 billion dollars between 19 countries still isn't that significant when compared to other budgets.
Koller's PGM was fun but very hard to generalize outside of the problems presented in the class. Opportunities to implement loopy belief propagation just don't seem to come up as much ad I'd like.

I had one of these until the hotend somehow died on me. Unfortunately the most of the chinese printers do not believe in open-source or GPL, so I'm planning on completely replacing the X-carriage and upgrading to an E3D-Lite6.

I would still recommend the printer as it does come with everything. A few kits that do seem nice like that Makerfarm Pegasus (which does come with the Lite6) is missing power supply and glass.
Why would the driver need to stop?
Topsoil.
That's really cool - with those settings, you could run it on a single charge of one of those cheap 20,000 mAh portable batteries for a month.
People are downvoting because this comes off as a derail, but actually this is a really important criticism of the US government to make. Even if you assume the purpose of DOD spending is National Security (a term abused so often, saying it makes me cringe), well ok. Climate change is a huge threat to national security. Congress needs to reallocate some funds, and it's really unfortunate that discussing the reduction of defense spending is so taboo in the mainstream.
I think there is plenty of evidence (of how types help to design better APIs), you just don't want to accept it. I already mentioned LINQ and lens, another could be parser combinators and FRP (Observables in particular).

Recently there was an article about a whole application: http://abailly.github.io/posts/cm-arch-design.html

I can also recommend book Functional Programming in Scala, which talks about how FP helps develop good API in more detail.
I'm the co-founder of a company that provides "elastic customer service" (influx.com) and I'm happy to share with you what I see happening in practice.

Most founders start out doing customer themselves. This is absolutely the right thing to do for reasons outlined elsewhere in this thread.

When the business grows, the the founder(s) can't continue handling 100% of customer support, both because there other priorities and because the volume grows beyond what the founders can personally handle.

Generally in this "transition phase" time-to-first-response grows steeply.

I wrote about my experience providing customer support on a open source project, you can see where the "wheels started to fall off" - ie time to first response climbed steeply:

http://moniker.net/2013/07/10/two-open-source-emails-a-day-f...

At the time, I felt bad about TTFR growing steeply.
I now understand that it's a really common state of affairs.

So at some point, the founders need help, and they either hire or outsource, or do a combination of both.

You asked about "the average time it takes you to resolve customer queries". A typical time-to-first response before Influx starts working with a client is 12-15 hours, with a outliers at 1-2 days.

On "stay close to your customers" - it's 100% correct but a harder question is "how do I stay close to my customers and scale at the same time?". The answer depends on the size of the business. I see people using a combination of metrics and qualitative insights. The metrics look after big picture health and qualitative insights involve customer support staff bubbling issues back up to the product+dev teams.
The original Civilization game, pretty much blew my mind.
As I said, your Photostream is just the last 30 days of photos from any device said to upload to it. This allows automatic import into other devices, if you aren't using iCloud Photo Library (or if some devices can't use it)

I've definitely had some issues with their iCloud related Photo systems, but the little messing around I've had to do has been worth it for the functionality when they work, IMO.

I like the idea of building a reference system in.

One thing to note is that you actually validate the user owns said account on another site.

On B/S/T forums back in the day, a semi-common "scam" was an impersonating user saying "here's my 1000+ feedback eBay account", which may have the same username but they did not actually own.

"Normally, component A completes then sends a message to B, who blocks while a file operation occurs, and then sends a confirmation to C which updates the UI. When configuration option D is enabled, B must make the write twice because of X, which requires component E to act as a delegate to intercept the normal message from B to C so that this can occur without changing the implementation of C, since it has been externalised and is used in six other projects. Also, file writes are disabled on weekends, except the fourth weekend in February, unless this weekend doesn't occur."

HBX Core

http://hbx.hbs.edu/hbx-core

Its a paid online business course by Harvard Business School with 3 modules - Business Analytics, Economics for Managers, Financial Accounting

Material is not super challenging (maybe except for Accounting), but its still a lot of work and very rewarding. There is a strong social element to the course because they incentivize students to ask and answer each other's questions. At the end of it, you have to go to a testing centre and give a 3 hour exam on everything they have taught you. I finished this course a few months ago and really enjoyed the material and all the people I met through it. Highly recommend!
this looks like [+] an excellent course, if only b/c it uses a text by Artin.

Ya, but you could do that little bit of stuff in less time then it took to write up the spec, put up the work, sift through potential contractors and ensure what you got met your needs (going back to step 2 when it didn't). Plus you would know how it fit together since you wrote it so it would be somewhat easy to alter/reuse.

As far as side projects, 40 hours a week to work isn't that much. I usually work 50+ and have most of my work life. Lots of people work even more. If you did this you would have at least ten hours a week to work on a side project. Incidentally, I still have spare time. To do things like post this comment. What are you doing with your spare time? Video games? Movies? Facebook? Might be worth looking at. Life is short and you don't get time back.

Start small. Do a little project. Something that takes 8 or 10 hours. Then, with that under your belt tackle something bigger.
It definitely is difficult. No doubt about it. Here are few things you need to remember (or things that helped me):

1: Break down your ideas into smaller ship-able chunks

2: Once you've something presentable, start getting market feedback to see if it would make sense going all in

3: If you don't see much interest, don't give up hope, sometimes it is better communication sometimes pivoting required. This is where you'd decide where you'd like to go. I found reddit to be tremendously helpful in getting feedback.

4: This probably is special case for me but I was giving up on software and getting little depressed / overwhelmed with my current stage in life. I like to do artsy stuff once in a while and so I started getsatvik.com, no-one has bought anything yet but this helps me learn marketing, copywriting and understanding how to sell. So think what you'd like to do as a hobby maybe combining that with your ideas could keep you going.

5: I find teaching people is also a great motivator. I now run a regular meetup in my city, learn some new concepts every month, teach them to other people. I don't get paid for any of this but helps to keep me sane.

6: Sometimes having virtual buddies also help. I now have a 'friend' on reddit who helps me with quick feedback / writing critique (as English isn't my first language) and I help him with doing some programming / teaching.

7: Nothing new or revolutionary here but sometimes connecting with like-minded individuals and organizing an accountability group also helps. If you'd like to connect, I'm happy to be your virtual-buddy!
I don't think anyone has said this yet: Use your lack of time as a motivator to distill your side project down to the simplest thing that could possibly work (MVP). This is your opportunity to get really good at that. If you can't test out an idea in a weekend, you need more practice at this not more time.
Why do you think there is a greater shortage of oil than of rare earths? The point with both is the extraction. The U.S. has a lot of oil wells, but there is only one working rare earth mine in the U.S. http://gizmodo.com/the-strange-second-life-of-americas-only-...

Rare earths may be abundant, but that doesn't matter when the type of mining required to extract them is almost impossible to do in much of the world because of the environmental implications.
thanks for pointing that out. I've updated the OP to add that + correct the typo pointed out below
I've been waiting for a solution like this specifically for digital nomads. (It's also on my own to-build list so I might punch it out one of these days.)

My unsolicited advice: Market it to digital nomads exclusively.

I get that it's open sourced, but I don't like that and don't think it makes sense for the nature of the project... I'd prefer someone treating it like a startup and maintaining the product, making a nicer design, growing it, etc.

There are many good robotic parking systems, but the US-developed ones tend to be one-offs, and are not engineered well enough.

The design problems are mostly basic mechanical design problems. Some systems park a car on a flat pallet, then move the pallet. This has the risk of the car rolling if the brakes don't hold. The more robust systems have a curb on both sides of the pallet and depressions for the wheels, or curbs that rise at each end. (This should be mandatory in earthquake zones.) This also gives the driver more guidance on getting the car positioned properly. The modern systems all check with light beams for proper positioning, but it's better if there are also physical obstacles.

There are palletless systems, where rows of rails rise up under the wheels and lift the car for transport, but those seem to be less popular.

The better designs have more than one retrieval mechanism that can access each slot, so if one fails, the system can still operate, but more slowly.

The lifts have to have the usual safety devices of a freight elevator. There is no excuse for an elevator falling, which has happened.

The usual problems of exposed machinery apply. Everything has to be built for a wet, hostile environment. Optical sensors must survive dirt. Limit switches must survive being banged on. Motors must be weatherproof. Some of these parking systems are repurposed automated warehouse designs, and that's a marginal approach. You want someone on the design team who's designed for a harsh environment, like railroading.
"Move fast and break things" will not work.
Correct. It's not a project effort, but not very much would change if it were.
I actually wrote a long post about this exact topic because I am sick of the meme that good ideas are nothing [1]. If anyone has any ideas that hit 10 or more checkpoints on my list let me know so I can steal it from you :)

Stop reading, start doing.

Imagine someone asks how do I train to run a marathon?

Start by running 1 minute a day and add a minute every few days, after 2-3 years you'll be running long enough to run a marathon.

There is no substitute for doing, there are no shortcuts, there is no miracle pill (well, ADHD meds may help...)

You must actively decide that your sideprojects are more important than whatever else you are doing, speaking of which now that my two kids are asleep, and my fiance is reading, it's time for me to stop commenting on HN and start working on my side project.

Time is not something that is lost or found, you have a fixed finite amount of it, and it is continually decreasing the only thing you can do is choose what you do with it.
Weekends have plenty of time.

But any good side hack will just make the time for itself. It's that stuff you can't not do so you stay up slightly late and will be slightly more tired at work but hey, so what, you'll feel so good about it that you can't wait till the work day is over and you can continue again. Then it'll fade away and you'll get more interested in work again until one night you figure out where you left with the side project and hey, there you go again.

Personally, I've never been in such a good job that I would always have interesting things to do. So, I've observed that my home-hacking is strictly proportional to the amount of boring stuff at work. I need my dose of programming and if I can't get it at work, I'll get it at home. This kind of takes care of side projects on its own.
