Well... there is a lot of tech stuff in the US funded by the government, but the wildly successful Silicon Valley style "startup scene" usually isn't really where that money is sent. More like SpaceX/Tesla/etc, a few solar panel manufacturers, and large businesses.

I don't think it's about marginal cost, it's psychological. In these people's minds, giving a teenager a box of condoms sends a message: "It's okay to have sex".
Nonsense. Marco may be frivolous and scatter-brained but the man has some serious brain power. He's a very effective duck tape programmer and does some hard algorithm work along with serious UI polishing. There aren't many millionaire independent programmers who succeed based on the quality of their programming without much business and marketing acumen, but Marco shows it can be done.

My concern here would just be parental knowledge. I would permit my daughter to get an IUD at a young age if that was her decision regardless of our families religious / moral views (though I would encourage her to be informed), but if I'm responsible for her health and safety, I damn well better know what someone else is implanting in her.

The semantics of POSIX dirents haven't really changed, and any file system complexity is abstracted by the kernel's VFS subsystem to provide generic data in all cases. So, yes, it is possible for something like 'ls' to be finished, or at least for really long times.

That sounds vaguely like diabetes.

In the absence of metabolic disease, the body breaks down fat to use the resulting energy. Think about it evolutionarily; "there's no food right now, time to jettison my energy stores"?
No worries! I was upset back in 2008-9, but now I consider that I've learned a valuable lesson about the nation in which I live.

You've turned over another rock to find another example of GS malfeasance, so thanks for the info, but you're wrong about economies in the long term. The fact that GS was backstopped by the public in this case, and that their ownership of Treasury had so much to do with that (now I see why a knucklehead like Geithner was fast-tracked into his current position), will inspire not just GS to keep doing the same thing, but everyone else in the market to emulate them. Next time around, all the amounts will be bigger, maybe even big enough to break the nation, but since everyone at every department and agency will be a puppet of some financial firm, our reaction will be even more corrupt. All because Bush the Lesser didn't have the stones to tell Paulson to go pound sand when he started his high-pressure sales routine. The seeds of future disaster were planted during this pretend disaster.

I've heard all the whining about pension funds and whatnot, but surely they weren't all all-in on GS and its ilk? When the stupid investment banks fail, the big institutional funds might drop 10 or 20%, but life will go on. This is an example of the well-known fact that sometimes securities decrease in value. The services that GS provides, others could provide just as well. The damage that was done to good regulation and fiscal prudence in this nation, will never be fixed.

Systems with moving parts undergo lots of stress. At some point, they will fail. Regular maintenance limits this; and the maintenance prescribed even for light aircraft keeps it to a minimum.

Still, no system is ever 100% reliable. The typical safeguard for engine failure in light aicraft is to glide to a safe landing. Starting with basic training, you'll do so repeatedly (starting from the vicinity of a landing strip, of course) and should be able to bring a plane down safely. Some (very) light planes even include a parachute system that'll bring down the plane in a manner safe for its occupants.

Speaking as a private pilot with little experience, this systems seems promising to me in two respects: In the case of a failed engine, it'll take you another 20 km or so. This can make the difference between a survivable landing in a field somewhere and a completely safe landing on the closest airstrip. Additionally, you get 40 hp or so of available power in situations where you need it, like taking off or going around after a botched landing. This could allow for shorter runways and help speed your initial climb, which is generally considered one of the most dangerous phases of flight: At that point you are both flying slow and low, and both speed and altitude are important safety aids. After a cursory first look, this system appears to be a considerable improvement in safety while avoiding much of the complexities a true twin engine system would entail.
No, I (sic)ed 'bug free', because this is a goal that may never be achieved. I want to say "try as hard as possible" but did not want to look like I think it actually IS possible.
The commercial version compiles QML into native code.

> I wonder if you could use your propeller as a "wind turbine" when landing to recapture some energy?

Helicopters do this, it's called autorotation. They spin up the rotor while descending and then trade the rotational momentum for a little bit of lift to make a safe landing. It's a tricky maneuver but a part of every heli pilot's training.

I doubt that it's a viable strategy for light aircraft, though. The loss of airspeed from extracting energy out of the wind stream is more dangerous than gliding. Thermals aren't powerful enough to keep a non-glider aircraft in flight as far as I know.

Large aircraft use a small windmill or a ram air turbine to keep hydraulics and electrics up in case of a loss of power, though.
Thanks! I think the latest build (v1.0.9) has everything you mentioned except #4 and #6.

#3 is not the default though. You need to go into preferences and switch Query Execution mode to be 'execute current query', rather than 'execute all'.

The Model Complexity Myth
Harbingers of Failure [pdf]
Light aircraft engines are already _very_ reliable, you'll most likely spend a career flying without ever experiencing a failure. The most popular GA motor, the Lycoming O-360, has been in production for something like 60 years, and is pretty much "debugged" as far as engines go. Still, failures do happen (most often because of user error). You can switch to turboprops, and you'll get more reliability, but higher costs. You can switch to a multi-engine plane, but again costs are higher.

An electrical motor which can provide backup assistance without causing further single points of failure is a nice add-on if they can make it work (I'd be sceptical about trusting this thing without extensive testing.)
Hopefully he can return to hacking Erlang now.
A really interesting BBC show on the subject of intermittent fasting: http://www.bbc.co.uk/iplayer/episode/b01lxyzc/horizon-201220...

I've been experimenting with alternate-day fasting for a while now. I allow myself whatever I want for breakfast (usually cereal with fruit, or oatmeal) and then I eat _basically_ nothing until breakfast the next day. If I really want one, I'll eat a banana or a grapefruit after a run.

An interesting observation is that I have absolutely no problem exercising on fast days. In fact a 5m run feels great.
This would be an awesome mobile app. I'd pay for it.
Redundancy is a well-accepted (at least in aeronautics) way of providing robustness. When designing onboard systems for aircraft, it is not unusual to have a function with a higher level of design assurance which is implemented by a set of similar devices with a lesser level using a majority vote.

See multi-version dissimilar software: https://en.wikipedia.org/wiki/N-version_programming

Furthermore most modern planes are designed to be able to fly with one engine inoperative, even those which have only two engines.
If we ever get to tame energy I don't think we'll need to care about water and food. It seems inefficient to tame energy only to then invest more time in food research to give our bodies energy.

There's also, I fear, a trap here where we believe we understand nutrition, only to discover there are nuances that we still don't have a great handle on.

As an example, there's the emerging posibility that one's gut flora can have a huge impact on overall health - and that certain types of foods can have a negative or positive impact on that gut flora.

Manipulating basic elements could easily lead to our skipping over critical parts of our health needs, with unintended consequences down the line.

Put another way: our dietary habits and nutritional systems developed over tens-to-hundreds of thousands of years. I'm very leery of any theory that we can easily replace that.
Thing is though, it is okay to have sex—safe and consensual sex, that is.
Your comment is absurd. "A finished project is a dead project?"
>All they are is an app with some marketing, and anyone with a bit of money can easily come up with a competing app.

I think I'll let your first statement stand, but in regards to the second. Uber has raised $5.9bn dollars, is doing ~2m rides per day, is in 300+ cities -- sure you can create a competing app, but the chances of meaningfulness are small if non existent.
Here's the link to the study referenced in the article.

The interesting thing is that we've always had a murder problem: https://en.wikipedia.org/wiki/List_of_countries_by_intention.... We've been at 5-10x the per capita murder rate of England and Wales going back to at least the 1910's. It looks like between 1910 and today the lowest rate in the U.S. was 4.0 murders per capita, in 1957. That same year, England and Wales had only 18% as many murders as the U.S. per capita.

I think the scale of violence here is really hard for Europeans to understand. New York is one of the safest large cities in the U.S., and the murder rate there is more than 3x that of similarly-sized London.

That is the principle of a ram air turbine. It's a small wind turbine which can operate as a power generator while the plane is flying.
I learned a lot from a beginner's art class a long time ago. The teacher threw some rope on the table and said "Here - draw this."

Problem - I can't draw. I have no idea what I'm doing. I am completely terrified of making some kind of horrible messy fuck-up non-art and...

To keep it short - it's all fine. I'm not Durer, and I sketched something that didn't look much like rope. But it was way better than I expected.

The takeaway: there's a kind of pain barrier with a lot of projects. You think "This is not working, it's not going to work, I'm totally wasting my time on it", and all kinds of other critical thoughts.

Then you keep at it, and often - usually - it all works out.

The one exception I've found is that if projects for other people feel stuck, there's often a good external reason, and it's possible that you're genuinely wasting your time on them.

But if it's a solo project and it's not working, you don't have to force that iteration to work. But if you keep pushing and iterating and changing, something good falls out. IME the intense frustration is often the sign you're on the way to a breakthrough.
Greek Finance Minister Yanis Varoufakis Resigns to Aid Euro Zone Talks
Dismissing opposing view points as koolaid is a bit weak. Just accept people don't agree with you. It's okay. We can both be right and wrong here.

I see it as a comedy, not a statement on modern day gender roles. People relate to stereotypes even if they don't live them. Children relate to them, it doesn't matter that it's the dad or the mum, every child has had a moment when their parent doesn't pay attention to them, or over reacted, or they over reacted, so the scene will resonate.

You can still teach your children to recognise stereotypes for what they are. Rather than boycotting exposure to them.
I see i forgot to include that i think the couple was both well into their 20s, just not married (yet).

Plugging my own relatively new podcast, Theory and Craft (http://www.theoryandcraft.fm)

Each episode we take a paper or topic from the research world and discuss how it applies to us as practicing software engineers.

I'm also a big fan of:

* http://giantrobots.fm/ - pretty wide array of topics (tech, design, business) covered by a Boston-based rails dev shop

"Book author" is at least closer to the truth. There are editions and old copies floating out there, it's hard to estimate completion dates, and authors have many of the same copyright problems. The difference is that software must live in a dynamic and shifting 'house' where everything gets rearranged by vendors, probed for weaknesses by attackers, and new features are constantly demanded by the users. Solutions to all of this are tacked on as an endless stream of appendices. Throw in patents for extra insanity. Both analogies strain to fit this reality.

Edit: That brings me back to the article. "Finishing software" just means we should act more like authors. Very hard to achieve when you think of the differences above.

I disagree, based on personal experience. I have a few projects no longer in active development, but I use them frequently. They do what they are supposed to, they don't break down and require no maintenance other than changing the expiry date on the credit card associated with the hosted account every few years.
This is awesome. Seriously. I never go through the regular "Who is Hiring?" thread because I don't have time to comb through a humongous list of unfiltered text posts, 90% of which aren't relevant to me. There have been other attempts to format the thing, but this is the best I've seen so far.

If you eat around the same time daily, your body learns to get hungry when the time approaches. Regular breakfast-eaters get hungry if they skip breakfast, while breakfast-skippers like you and me do not. (If I'm wrong and someone in normal health has tried skipping breakfast for a few days without losing the morning hunger -- assuming they're making up for it later in the day -- I'd like to hear about it.)

I started skipping breakfast not for intermittent-fasting benefits but in hopes of better sleep: the anticipatory appetite can contribute to waking up early, and my sleep needed help.

Added: the article supports this. "The rise in ghrelin is independent of meal timing as demonstrated by similar peaks before an anticipated meal in various meal frequencies, thus suggesting that subjective feelings of hunger and energy intake is highly dependent on the individual’s preferred meal pattern (76)."
As a counterpoint, 85% of the gains were found in neighboring counties without the program. Teenage birth rates are plummeting everywhere.

I'm guessing that materialized views can be sped up if the distribution of the component row keys can be mirrored across tables, so that the materialization can be treated as local and no internode communication is necessary.

Doesn't sound like a play against Uber -- seems more like a companion concept to self-driving cars, which would naturally be good candidates for commuter ride-sharing.
Interesting how they limit the drivers.

I assume this is from the driver-as-employee lawsuits Uber is facing and Google wants to be safe.
Right, this is actually a ride share/carpool service, not taxi like Uber.

I think we'll enter a paradigm where R+D costs will drive the price of successive generations of CPUs back up to the level of the early '90s or even before. We're near the end of the road scaling down the same designs with improved photolithography techniques. Eventually, we'll find a new dimension to optimize on, and then rapidly progress in that direction, which will lower prices again.
Whom does the collective "we" refer to in "we'll spend billions of dollars in R&D" ?
Yes, it is just "sugar", but it cements one way of doing things.
If it's anything you expect other people to use, then I'd consider anything that hasn't been updated in the past year "abandoned", yeah.

If it's your personal projects though, I don't make that assumption.

Ketosis is a pretty weird state brought on by lack of carbohydrates. The liver starts producing ketones, ketones rapidly breakdown fat cells to boost blood sugar.

It is mostly unrelated to diabetes as that relates to insulin response.
> I've always heard that you should have the most calories and greatest diversity of food at the first meal of the day, slightly less so at the midday meal, and a very light/low calorie dinner.

This theory seems to ignore how effectively we can run on glycogen reserves, and sounds like it assumes a full night of sleeping takes less energy than a few hours awake. Also, most nutrients don't need to be consumed just before you're most active; the body can figure out when to use what, and a lot of resources go more to "repair/maintenance" than "fuel".
A significant fraction this slowdown relates to Intel’s integrating graphics with their CPU's which not only costs silicon, but also adds heat. Intel has then traded most of their process gains into improving the terrible graphics performance to a near acceptable level at the cost of minimal CPU gains.

Sadly without real ed: competition Intel quickly stagnates. And AMD is still far behind the curve.
