Other than costs, another advantage of flying the first stage back is that they can be analyzed to see how all the components perform or wear, and the design improved based on the findings. It's harder to do that when you crash them into the Atlantic every time. Over time, this could mean that reusable rockets are actually more reliable than one-time use rockets, though only if you fly enough times to get the benefit of evolving the design.
Actually, it probably can't, at least in most of the cases where it would matter. The President can get the ball rolling in some of those cases, but in others there may actually be an act of Congress required, or other bureaucratic hoops to jump through.

The President is not the equivalent of the CEO of a private corporation. And like so many of the things around technology in government the last couple of years, this one is probably more for show than anything else.
I don't know about this. His complaints seem to be that the pool of applicants is largely made up of highly coached overachievers, and that standardized tests and an hour-long interview aren't enough time to get to the core of whether someone will be a good Harvard student or not. I wouldn't call that a "sham," more like a systematic failure to recognize, highlight, and quantify the many forms of achievement and merit. A sham to me would be that someone upstream from these reviewers is throwing away all this data and just accepting a pre-formed list of rich white people.

Evaluating students in the first place is an extremely hard problem technically and philosophically. That Harvard even has in-person interviews for all its prospective students suggests it's less of a sham than many other admissions processes. Does this guy think the all the other schools are giving five-hour interviews, or psychological test batteries, or brain scans?

You have to decide who you're going to let in, and so far no one has found a really reliable way to separate the wheat from the chaff - that is, where the wheat is the type of student you want. Even selecting a 'type' of student is risky, considering people at the age of 16-18 are essentially larval. So not only do you have to gauge performance, but potential. Good luck with that!

There's also an ignorant undercurrent of "kids these days," as if kids in the 90s and before didn't have advisors or vanity trips or ultra-practiced answers for every question. The way he got in is the right way, even though as he points out shortly after, there is no right way.

"Conceive" doesn't equal "healthy child born". Plenty of pregnancies end in miscarriage and that rate increases with age.

I think the other states on the wiki page make more sense. 66-44% of 35-40 yr olds will have conception resulting in a live birth within a year.
Yea, that's why I put it in the comments. I'm surprised it didn't get down voted quicker.

Rust guy here, and I can tell you that there is a huge contingent of our community made up of dynamic language programmers who have been seeking experience in systems programming. That said, when it comes to systems programming understanding the system itself is just as crucial as understanding the language, and that takes time. If getting up to speed quickly is important to you, perhaps you'd like Elixir ( http://elixir-lang.org/ ), which is sort of a Ruby-esque language that runs on the Erlang VM.
I'm not positive on this but I believe Tesla either uses technology or licenses patents directly from Mercedes-Benz regarding their whole "self-driving" and "autopilot" marketing here.

Case in point: my current car does a variety of self-driving tasks such as:

- Autonomous braking

- Active lane keeping assist to steer you in the lane if the radar and cameras detect you are swerving

- PRE-SAFE collision prevention plus that will autonomously brake if it detects an imminent impact

- Pedestrian awareness system that will autonomously brake if it detects a pedestrian is entering the range of the long, medium and short range radar

- Distronic Plus that will accelerate and brake according to both the vehicle in front and behind you from 0 mph up to 100mph

- Attention assist that employs various sensor to detect drowsiness and alert the driver audibly and via haptic feedback if it's time to take a break.

- Active blind spot assist that will audibly, visually and via haptic feedback alert the driver that a car has entered your hotspot and prevent you from entering that particular lane

So while the Tesla camp is and should be excited about "self-driving" enhancements, Mercedes-Benz has been doing this for well over 2 years now with some of the technology above even becoming standard features on non-high end Mercedes vehicles such as the S-Class with the appropriate packages.

I don't really see much but hype with respect to Tesla's announcement.

Scientists invent new way to control light, critical for next gen fast computing
We[1] have a multi-domain mail server container with imap, pop, GUI admin, webmail, and spam lists that is basically ready to go, based on LXC.

You can launch the container in seconds and should be the fastest and perhaps easiest way to have a fully functioning mail server. There is a starter guide [2] and even a [3] video to get you going.

However a mail server unlike most other apps is not only complex to install - which we try to address - but also complex to run.

For most if not all users mail just can't fail and this needs a fair bit of knowledge of dns, smtp, spam prevention, security. I think in all but the most committed cases it can prove a bit overwhelming for the average user.

It looks like Tesla is just trying to play catch up with some other companies. Volvo already has a car with self driving technology, Chrysler also has a very good near-self-driving system.
Raspberry Pi should acquire Arduino. They are complementary and have lots of wonderful synergies.
I believe they are integrating with hospital systems and standardizing data just like Akido presumably with the goal of getting into every hospital just like you.

I'm sure both Apervita and Akido would love to have a monopoly on the data and hospital network, but it doesn't seem like that is a guaranteed outcome. (So this is perhaps merely a very good business rather than an amazing business.)

But, instead of simply offering an API like you they want developers/scientists/doctors to build on a proprietary platform for a proprietary market on top of their proprietary API.

So they're Akido + Google App Engine + Google Play for health.

These guys raised $18 million, so some serious people believe in the company. But, I just don't understand the virtue of trying to lock all customers into their "Google App Engine + Google Play".

No one in their mind would build a business on that if they could go with a more open alternative, right? And now you are an alternative.

Though I think it would be pretty cool if you guys had an added offering that made it easy for hospitals to buy little apps... um I guess something like Apervita. :)
There's quite a few manufacturers that have this technology other than Mercedes
I also noticed the attempt to change what I actually said -- "any bill they wanted" to "any bill Obama wanted", which I didn't say.

They had a majority in both Houses and could thus have passed any bill they, collectively, wanted (in fact they did it without a single Republican vote, and without allowing any amendments or even very much debate).

They passed that bill. Obama then signed that bill. That, my friend, is factually correct.

Why this desperate attempt to make it somehow the fault of "Republicans"? How about taking some responsibility?
As mentioned elsewhere, this will be rolled out as an OTA update, people wont have to replace their cars for this
Well, in the EU, including Britain, it's all subject to the same data protection regime so that's half the battle already. The EU is pretty good at this sort of standardization so the scientists would not in fact have to start from scratch everywhere. Also, the UK and Ireland have a special relationship, cooperation on cross-border scientific stuff is the norm already.
Not all of it, some of it - yes. In particular, the Blind Spot assist systems are prevalent in a few different manufacturers.

The more advanced "self-driving" systems are all Mercedes-Benz technology that is part of their high-end vehicles (and not a standard option). Remember, Mercedes-Benz holds over 80,000 patents on this stuff and more coming all the time. There's no doubt they are pioneers in vehicle safety systems including self-driving cars.

Edit: Mercedes-Benz actually omitted quite a few even more advanced "self-driving" features from their new S-Class since, even though the technology was ready, regulatory requirements and drivers themselves were not ready for pure self-driving vehicles. (Taken from an intervew with Marc Andreessen on the new technologies in the S-Class).
I think money incentives are so good. Gives those blackhats a reason to help.

This data is really valuable to gauge OS & browser usage. Like anything, I would expect it to have some sampling bias in it, but I can't think of better sources for this data. Google, perhaps. (does Google release this type of data?)

I would love to see some history to understand what's growing, what's in decline, and how rapidly.
Still better than their non-existence.
Health care US style is enough of a barrier to contracting and start-ups that it seems a pretty reasonable topic for a site focused on exactly those groups of people.
The US Government already controls Comcast and Time Warner Cable through the regulations in the telecom industry, the FCC, and so on. The Feds, for example, can easily interrupt their merger at any time they see fit. These companies are government regulated monopolies (or at the least near-monopolies), much like AT&T and Verizon.

The problem with Google, as far as the US Government is concerned, is that it is not a government regulated monopoly. They fear anything with such vast scope and influence / power, that they don't have a certain level of direct control over.

The purpose of pursuing Google on anti-trust is to bring them under supervision of the US Government. The same reason the Feds were interested in Microsoft. It surprisingly takes very little to cause anti-trust problems for a major company, as little as one powerful senator dedicated to the issue. Google will be brought under a consent decree in the next few years most likely, and by the time the Feds get around to doing that, the market will have likely already made Google's dominance in search a lot less important.
Sure, but as has been pointed out, pricing doesn't just include the cost of manufacture- drug pricing includes the ability of the country to pay for the drug. Pharma amortizes costs globally.

Also, many companies have compassionate care programs to get access to people who simply can't pay for expensive biologics.
Mercedes-Benz has had this technology for maybe 5 years now.

The car will audibly, visually and via haptic feedback through the steering wheel alert a driver if the vehicle detects they are getting drowsy. Nothing new here.

Patriotism is not a virtue, it's a pretty empty and meaningless value
Currently, most offices only need face time ~10-4 most days, but if your driving your out of touch with coworkers in normal business hours which is a hard sell. So often people only get to miss one of those segments either the show up ~10 most days or leave by 4pm most days but not both. Or, they might miss 1-3 days a week depending on meetings etc.

Now, suppose your self driving car let's you work while in the car. So, your still in the office from ~10-4 and get daily face time, but your only working 8-6. From a work life balance that's effectively zero commute time vs a killer 2h each way, with the added benefit that you get to avoid some of the peak traffic times.

The upside is it makes vary long commutes viable, the downside is it's it's vary energy expensive but with electric cars that's far less of an issue.

No to mention things like effective valet parking everywhere.
Time for a history lesson. From 1922 until 1981, the only insulins available commercially were extracted from bovine and porcine pancreases -- a process which was both expensive and dangerous, since if the product was insufficiently purified it could cause life-threatening immune reactions or carry diseases from the animals used. (This is why insulin-using diabetics are to this day not allowed to donate blood in most of the world.)

It took sixty years between discovering insulin and figuring out how to produce it biosynthetically (all modern insulin is now produced by genetically engineered yeast or E. coli). This yielded so-called "regular" insulin, which -- at the concentrations necessary to make it feasible for injection -- has the unfortunate property of hexamerizing. As a result, it has is peak activity about 3 hours after injection, and ends its activity around 6 hours after injection -- compared with endogenous insulin, which acts within 5-10 minutes, but is excreted 24 hours/day.

In 1996, we finally had "rapid" insulin -- Insulin Lispro, which adjusts a couple amino acids in order to prevent hexamerization. This makes it act roughly twice as fast as regular insulin, roughly matching the time taken for a meal to be digested and to enter the bloodstream -- thus reducing the postprandial "peak" and cutting down on the chronic hyperglycaemia related complications of diabetes.

Remember how I said that regular insulin stops working after around 6 hours? If you want to get 8 hours of sleep, that's not so good. In the 1940s and 50s some modified insulins were released which "slow down" the insulin so that it lasts for longer; but it wasn't until 2003 that the first "24 hour" insulin was released.

So why is insulin still so expensive, 90 years after it was first introduced? Because the insulin we're using now is a heck of a lot better than the insulin 90 years ago. You might as well ask why a Tesla is so expensive when the Model T was launched over a century ago.
Mandatory vote is a good start, and will encourage more people to think about their government. In addition, get rid of electoral college. Add verifiable secure online voting and promote a system wide education of the people on the benefits of political envolvement.

Even during the deepest point of the post-1980s recession, unemployment never exceeded 6%. In fact, the highest level of unemployment Japan has experienced since 1953 was 5.6%: http://www.tradingeconomics.com/japan/unemployment-rate

It is interesting that they managed to preserve low unemployment and increase the standard of living during about 20 years of flat economic growth, but they've done it. Part of it can be explained by the fact that layoffs are rare (companies almost always assign employees to do unnecessary work rather than lay them off), but that is not sufficient to explain how Japan maintained the world's second-highest GDP during the "lost decade."
Makes me wonder if/when the market for this grows, if we'll start to see financial products built on this (maybe to help offset the costs of such, or to hedge risks for a company that may solicit in relatively financially risky behaviors?) à la egg futures[0] concept Hanson discuses?

You've hit the nail right on the head. People praising FP don't realize (but start to after awhile) that you should combine the FP paradigm with /OTHER/ paradigms as well. Your arsenal of patterns will help you write code. Don't limit yourself to one.
It's definitely true that there's a large quantity of pure mathematics that later turns out to be useful outside pure mathematics.

The question that's relevant here, though, is what fraction of pure mathematics is ever useful outside pure mathematics.

I think this would be difficult to measure. My guess: only a small fraction, but some of that turns out to be incredibly useful.
Well, just glancing at Volvo's website, their V40 car has Imminent impact braking, pedestrian collision avoidance, active cruise control (same as distronic plus), lane keeping assistance and blind spot assist.

Additionally they have automatic parking.

Missing from this is only the driver alertness detection.

This is cool, but "on Robots" is a bit dishonest.
Really it can only control robots, the "robot" has to have some exposed interface for a computer to control it, like the Firmata firmware for Arduino.

I forgive them though because they probably just call it "Ruby on Robots" for the parallel pun to "Ruby on Rails" rather than to make people think it actually runs on the robots.
"How dare Japan not fall under our rules, hurr durr"

Whole Asia is rising thanks to one and single fact - they stick to their rules. While whole western world is bending every possible rule to wage wars, shut protesters and buy votes.

As history teaches us east will collapse under its own degeneration of freedom so Asia can flourish. Then Asia will collapse in its self control obsession so the east world will flourish.

Its how the world rolls over and over.

The difference is that it's very, very simple to set up a political party and contest elections in the UK (it's a matter of a couple of hundred quid and some forms).

The hoops that parties (that aren't the Democrats or Republicans) have to jump through border on the insane in some states.
Immutability is nothing like explicit version control. So far as I know no language has anything close to explicit version control for state.

This is unfortunate, because it could potentially be a very useful if every single atom of data came with a built-in list of previous states, with timestamps, and with an identifier for the code/process that last changed the state.

Obviously, this is usually what debuggers try to do. But there's no reason why something like this couldn't be built into a language.

(Yes, it would be slow. No, it wouldn't be that slow if done right. It wouldn't even have to be slower than many other standard practices. But yes, it could potentially use a lot of memory unless given a cutoff. Even so...)

CS generally still seems stuck in the "memory is a line pigeonholes" model, and immutability seems to be a crude memory management hack, not a complete state control solution.

I sometimes wonder if a lot of the issues with state are caused by the fact that languages have extremely limited tools for dealing explicitly with representations of historical causality and past/present/future, and not because state itself is inherently evil.

He meant the radioactive waste from nuclear fission (with an I) plants. If I picked up the argument correctly, fusion was never meant to work, it was just a smoke screen so that people would not look too closely at what the nuclear industry was actually doing.

I don't share that opinion, though I think nuclear fusion power production - at least in the scales that would matter for the project of human civilization - turned out to be much more harder to achieve than what anyone had expected 50 years ago; and that some hard questions about the practical feasibility of that option went unasked for far too long. Out of normal human nature, of course. No need to cry conspiracy!
