I think when cars themselves came about, speeds of 10mph were considered breakneck and dangerous. I remember reading an old crash report where the author claimed that the driver must have been going at least 10mph and thought it was lucky nobody was hurt.

I guess to gain the trust of the public and politicians, self-driving cars must go through a similar process. I have met people who have said self-driving cars will never take off, never match the skill of a well trained manual driver and that they dont trust them. I guess it's slightly biased in that they have been driving for many years, one was my driving instructor and all are not considered technologists.

I'm looking forward to the experience, personally. I do, however, enjoy driving :)
I think Google wants to do a similar thing to Tesla. Maybe have a few of their own vehicles but bet big on the technology. They can then sell it to the big car manufacturers. With Tesla it's their battery technology, with Google it's their sensor technology.
You should assign the code to the employer of your own initiative simply because it's the right thing to do, and should be the status quo already. Propose language to this effect even if they don't know about it.

Blasts of Ultrasound Could Get Needed Drugs Into the Brain
Hehe, well, thanks for the correction. Yes on all of these things, I'm sure.

I should have said "the exact solution for the most basic justifiable approximation". Honestly, it's been 9 years since I last did quantum seriously, so that was the extent that I remembered.

Deriving Bragg's law in front of my quals committee and refusing to use "mirror planes" despite it being a Materials Science Ph.D. was just viscerally satisfying. It may not have been absolutely correct math, but at least it was way more justifiable than the typical accepted "solution" in my field =)
>> "It seems like they would eventually have a four-seater version but the bench seats could face each other."

I can think of two reasons against that.

1. People who get motion sickness get it 100x worse if they are facing the wrong way. There are also people I know who normally don't get motion sickness but get a bit queasy facing the wrong way.

2. If you are in an accident isn't it more dangerous for your neck if you're facing the wrong way. I know several cars currently (mostly people carriers) that have rotating seats but they can't be rotated when driving. I'm guessing that law is in place because rick of injury is higher facing the worn way.
I assume FTE = Full-time equivalent (http://en.wikipedia.org/wiki/Full-time_equivalent) in this context.

The influence of the atmosphere on orbiting objects is enormously dependent on altitude. Manned spacecraft usually orbit at extremely low altitude because they tend to be heavy and the tradeoff of regular reboosts is mostly worth it (manned space stations need regular resupply anyway). However, whereas the orbital lifetime of the ISS may be measured in mere years even just a few hundred km higher increases lifetime to centuries and beyond that to millenia.

Here's an excellent infographic on orbital debris: http://media2.s-nbcnews.com/i/MSNBC/Components/ArtAndPhoto-F...

You can see that most of the debris below 700 km has naturally been culled by aerodynamic drag, but above that altitude there is still a large amount of debris, most of which has an expected natural lifetime of many centuries.
In statistics, taking average on any distribution is perfectly valid metric that give you an expected value - even on power curve. For example, let's say you roll a dice and get a million dollar if you get 6 but nothing otherwise. Then your expected return is $1M divided by 6.

I was always interested this number: Sum the personal networth increase of each founder and divide that by number of founder years. That would give expected networth gain per year for being YC founder. Due to outliers, I think it would be significant number and actually makes a case for being YC founder.

One another advantage in calculating this number is that you can compare it with other accelerators (provided you have data for large enough number of founders for each). This would be interesting for rank accelerators from founder perspective (as opposed to investor perspective).
> Moar's development began in secret around that time

MoarVM's first commit was in April 2012, a year after Parrot commits fell of a cliff.

https://github.com/MoarVM/MoarVM/commit/51481efadbf5bbebfc20...

> Rakudo developers also claim that they decided against using Parrot because Parrot development ceased, but that's an obvious post hoc ergo propter hoc argument to anyone who looks at the chronology.

Maybe look at the chronology again?

> {MoarVM} seems to repeat most of the long-standing architectural flaws of Parrot

Such as?

> (Moar looked a lot like Parrot would have after the same time period. It was pretty disappointing.)

As you now hopefully realize, the time period was 14 months, not 29.
My commendations on how you guys handled this and how well you notified the user base of the change.
You could remove the seats and install an exercise bike.
> I made 2-3x as much by moving to California and then another integer coefficient greater than one when I moved to New York.

I don't think this is much of a valid criticism, since most people in the States can also move to SV/NYC and make 2x or 3x their current salaries as well. Hell, those cities probably have the highest numbers (so ignoring CoL) than most places in the world.
Trainstations are somewhat controlled, bus-stops are not, they can be just about anywhere.
Doing a "good" job of administering projects and issues seems to have a pretty steep learning curve if you want to use more than about 10% of JIRA's functionality.

I've been thinking about this a lot. I'll answer it two ways.

Negative:

- As we've automated jobs we've also created new ones, but lots of these new jobs are BS. Inspectors of inspectors etc. to fulfil health and safety regulations. We're also creating a lot of things that improve our lives or entertain us but are really just created so we have something to spend our money on. We don't need them.

Positive:

- I think the idea of a basic income would fix this. If we can automate everything and reduce the number of people that need to work AND provide them with a basic income, they can live their lives and not have to work. If you aren't anti-government you could even have the government owning factories, producing goods through automation and selling them to other countries in order to finance a good basic income for its citizens.

It's going to be interesting and if you are young enough likely something you will see played out in your lifetime. Although the changes in the 20th century were massive and world changing I think the changes this century are going to be ones which change how we actually live on lives on a very basic level. What we do everyday and how we get money. Even if it all goes to hell it'll be interesting!
Have they considered some kind of super heavy gravitational mop. Something big enough to attract enough small particles and just 'mop' them up and send them into the sun or towards Earth?
A very interesting application of this point of view was a proposed projector of Light Blue Optics. The projector would have the property that it was near 100% efficient: it would essentially steer the light to the desired locations (rather than blocking it out where it was not desired).

The idea is outlined briefly here:

As someone who is a native German speaker, I wasn't impressed. The translation to English was much better - because she spoke very clearly, slowly, and with simple grammar.

The translation was no better than, say Google Translate. A mashup of Siri + Google Translate wouldn't have been any worse, and both technologies exist for some years. This is, unfortunately, hardly a breakthrough. Rather a 24h API hackathon project ;)
Yes, I'm saying it's really about time they added it to the core, especially because it's been available as a patch for a long time.

I get that they need to differentiate their paid version, I just wish it was in areas where the community hadn't already provided something that works.

I guess this is actual disruption - lots of people are already complaining about loosing jobs :).
Dual-sim is awesome. Is there a way to have 1 SIM be soley used for data? The reason is that here you can buy a SIM package that's only data for a lot cheaper than a voice/data combined SIM. It would be awesome for me to buy pre-paid voice for when I call people (very seldom) and use the data SIM for anything data (which I use 99% of the time). Would save me a lot of money on cellphone fees.
Possibly - but maybe also because it apparently requires years and years of research to get to something that works properly. Not a lot of companies have the amounts of money and staff for that.
Interesting because you'll get the cleanest history possible, however have you ever had an issue when the rebasing post code review would have had unintended effect (and not caught by a reviewer) ?

Things there move fast in orbits, the gravitational attraction can't just "collect" them, not more than the Earth can. For example, ISS travels 17 thousand miles per hour, or 5 miles every second. Moving the "big and heavy" object around is of course much harder and energy demanding than moving the smaller objects themselves and the gravitation is unbelievably feeble force compared to all others.

The article gives the examples of the cheapest solutions already. It's impossible to imagine more expensive approach than using any other gravitation than Earth's.

The other constraint is that A0 sheets are one square metre in area. This leads to the neat formula for page sizes in metres being pow(2,(+ or -)1/4 - n/2) where n is the number of the sheet size. It's rounded to the nearest mm.

It's embarrassing but not too surprising that Vignelli confuses root 2 with phi. The culture of design and also architecture places a lot of importance on having things "just so" and much less importance on the reason why. It's an "uncertainty avoidance" thing, to use Hofstede's terms.
It's not uncommon to hear strange claims about exact proportions in the human body from architects, which is part of the same attitude.

There's a recent book of investigations of phi by graphic artists that is slightly more rigorous:

After the list of reasons people dislike it are resolved, it won't be Perl. It's fine to start calling a modern language Perl, even though the modern language has standard syntax that no current Perl programmer would consider Perl, and standard computer science constructs like OOP and Unicode etc that require coding against a different abstraction than Perl. Nothing wrong with that. But the new Perl would have as little to do with the old Perl as an iPad has with an Apple ][.

It would not be the same language in any meaningful sense, beyond branding.

I'm surprised taxi services are so far behind here. Why can't I request a taxi in a single click, select the vehicle, charge it to my account, see the location of the taxi on a map and the ETA until it arrives? Why can't I see the route it'll take, or modify the route myself and set a waypoint?

I'm sure some taxi services offer a couple of these features, but none of the ones that I've used. I think one had online booking, but it was broken and I had to find a phone, and then I got no answer, and then I was on hold for 5 minutes.

Why can't I set a custom alert, so I get notified when the taxi is 2 minutes away? That way I don't have to keep looking out the window, or spend 15 minutes sitting on a curb, wondering if they forgot, and I'm going to be late.

If taxis are losing business to Uber, it's their own fault, and lack of innovation.
Hi, Oliver here (the report's author). Actually, we specifically stayed away from contacting JRebel users simply to avoid any additional bias. Our charity approach (each completed survey donated to a charity that brings video games to kids in hospitals) that we didn't need to promote it as heavily to our own contact. We spread the word successfully through contacting RebelLabs subscribers, VirtualJUG and London Java Community (LJC) members and individuals in the industry. That said, there are certainly some JRebel users in there, although we didn't ask specifically.

My ideal for driverless cars would be that, eventually, the ability for the cars to communicate with one another and detect each other would permit increased speeds and higher vehicle density on the roads. At some point, a human behind the wheel of a car would be like a horse-drawn carriage or a farm vehicle on the road.

Most manufacturers don't even produce manual transmissions on the majority of their models in the U.S. any longer, and, in the models that do have them available, they're sometimes more expensive. More than likely, the manual driving controls would become something like the pseudo-manual shifting available on some automatic transmission vehicles: you get a little more control over how the vehicle operates, but you won't be permitted to do anything that will be likely to damage the vehicle. I think we're already seeing a lot of this in the safety features of some higher-end cars (collision avoidance/warning systems) and features like automatic parallel parking.
smells like bullshit

20k "jobs" / mo gives 240k jobs / year putting them in the top 20 largest private employers in the us [1] with just one year's claimed growth

edit: there may well have been a month where, for sufficiently lax definitions of "created" and "job" it is indeed true that "20,000 JOBS CREATED ON THE UBER PLATFORM EVERY MONTH" but I'm highly skeptical this claim is close to true in anything but the most generous sense

I agree with your larger points.

But I would point out that the "advanced" functionality of git that you're talking about is something 99.9% of people will never use. Hell, even branches is something that most people don't use.
I think this accounts for the increased use. I would go out of my way to avoid taking a Taxi because they're so inconvenient and opaque.

I still don't plan to start using Uber extensively because I'm used to walking at this point, but the combination of transparent upfront pricing, accountability, ease of use, speed of pickup, and seemingly typically lower pricing is a compelling case versus zip car. Definitely an actual competitor with walking and public transit, whereas I see Taxis as only really a competitor with driving.

About cleanliness, taxis and rental cars are clean because there is someone there to clean it between each customer. That doesn't work for carsharing, where cars go directly from a customer to the next.

My experience with these systems is that you don't find anything really dirty in the cars, but you tend to find empty bottles and things like that in them. Not a deal breaker if you just want to get somewhere, but not very family-friendly either.
There's this notion that because a service is free, the provider shouldn't give a fuck about the service they're providing, and the user better be thankful the service exists at all.

There's also this notion that if someone provides a service, even though it's free, they obviously have some business model or similar interest or they wouldn't do it, so they better give a fuck about their users, or their users are gonna hurt them as a provider by leaving for another provider.

I won't say which is right and which is wrong (I feel both are wrong), but the two are obviously in conflict. The whole open source community is based upon the former. Ad supported data-mining businesses are based upon the latter. Hence the conjecture by the OP.
My point being they are stating that their service is available to 137M people. The bay area is one of the top population centers in the US so I'm surprised they say they can get 40-50% coverage.
I think your estimate is overly alarmist. Without GPS, we'd use ground-based stations. It wouldn't be as accurate or as available, but it would still be good enough for almost everything GPS does. In fact, we already have ground stations to augment GPS. And even without ground-based stations, modern accelerometers allow inertial navigation to be quite accurate.

Also, GPS satellites are in medium Earth orbit, which is rather sparsely occupied. In a Kessler syndrome scenario, GPS would likely survive.
Funny way to arrange this comparison. To me it reads: for every Uber trip I take from my apartment in the Mission to my office in Soma, I would ride a taxi from 24th to 23rd street.

Every single first world country was either already a democracy before industrialization ("the west"+Turkey), was totalitarian until it was invaded by the US and forced to become democratic (Japan, Germany, Korea, Austria), or is comprised of people who fled a totalitarian nation to found their own democratic nation next door (Taiwan).

Same here. While I still consider a Taxi as something you only take when you're drunk and have to get home from a party, I've gotten used to taking an Uber or Sidecar for pretty much any trip that would require a muni or bart here in SF. It's gotten to the point that I am downright spoiled.

I think it's a very valid criticism if your best people (not talking about "most" people, who don't start companies and create new stuff) can easily move to another country (or other state inside the US) and earn WAY more for the same job or skill set.

It's not a valid criticism if the gov. footing 80% allows these companies to now offer SV/NY competitive salaries. Which I suspect will happen if they do it right (both the governement and the entrepreneurs).

I have no horse in this particular race, but taxi drivers also pay for fuel, their own health care, and I think generally self-employment taxes as well. So the actual difference is just the cost of operating the vehicle in wear and tear and depreciation. The latter of which is mostly relevant only if they purchase the car exclusively for this purpose.

So the $90k might be deceptive because it's not net, but it's a sensible way to compare to what traditional taxi drivers make given uncontrollable variability in car ownership expense.
It was about time, although I won't make any use of this feature.

Salted hashes have been irrelevant for at least 5 years, possibly more. It was a big deal in 1995-2004, back when "Rainbow Tables" were a thing. It just doesn't matter any more, and hasn't for a long time.

Don't be misled by the fact that bcrypt/pbkdf2/scrypt both use hashes, and have salts on the front - that's just a property of them, not their primary essence.
Some people care about performance, and ABCL is nowhere near SBCL in this regard.

I also don't know if ABCL's compiler is offline (generating class files from CL code) or on-demand (likely using OW2 ASM). While it is no longer impossible to do, it remains tricky to generate Dalvik bytecode at runtime, and the performance hit is significant (look at Clojure on Android).
For taxis, medallions are usually leased to drivers (few could afford one). This takes much of their revenue -- perhaps half or more surrendered to a medallion holding company just for the privilege of driving a taxi.
