Cool, great. Except that the Windows command line sucks and bash is uncomfortable to the point of unusability on Windows. I will use a shell (not bash) on Unix platforms where it is properly integrated and meshes with the rest of my workflow; this is not Windows, and attempting to attach it to Windows with baling wire does not work for me.

My experience with source control systems--you know, including ones that aren't git--is that you can generally find a good UI for them. SourceTree on Mac is great for hg and git. Tower is great for git, too. Even TortoiseHg is a country mile past TortoiseGit in usefulness.
My first thought about driverless cars is that stock in alcohol companies would skyrocket. I know a good many people who would go to the bar on a more regular basis and now that they have a driver for the ride home. Also on a week day after work, why not have another beer? No risk of hurting someone or a DUI, right?

>Still, I don't have experience with iOS devices, but my Nexus S tends to be so laggy at times that apps crash frequently.

This sounds more like poorly written apps than an issue from the article.

For example if you are scrolling a list view and it slows down to the point of crashing, the application probably isn't caching views or has a memory leak (application authors fault).

If your device gets sluggish and you get miscellaneous force closes I would look for applications with background services that are doing more work than they should be.
Are you sure about that? If it's the norm to pay for a share in a fleet of cars, then those cars will probably be owned and managed by a company that will ensure that they get timely preventive maintenance. Yes, there will be changes in how much is reasonable to pay for added durability, but do you have any evidence that cars need to be radically redesigned?

who are you to decide how "Linux" is supposed to behave by default?

I'm not deciding that, other people made those decisions decades ago. It's a bad idea to mess with defaults for no good reason and then being too lazy to at least package it properly.

Getting mad because Ubuntu's choices are different from choices you might make is just silly.

I couldn't care less about ubuntu, I'm not using it. I just hate to see that mindless crap trickle down into one of the last semi-sane distros (debian). This only leads to forks in the future which means more work for everybody.

Again: If some distro-maintainer wants a fancy motd then great, make it a package and make that package the default for the desktop-install. Don't mess with core-stuff that has stood the test of time since before said maintainer was even born. Down that path lies SuSE linux.
I'm really glad your wrote this. It's just the solution I'm looking for. Uber-geeks will always complain about custom scroll bars, but the rest of society appreciates the clean design.
Ever been in a taxi with 300k miles on it?
Actually, I think such a system would kill public transportation because it would become cheaper to use the cars than public transport.

I don't know the exact breakdown but my guess is that salaries of drivers are much more expensive than buses and gas, especially given those are often unionized jobs with very costly benefits (pension etc.).
It is actually one of those famous interview questions. Kinda like the Microsoft one where they asked you why are manhole covers round. Totally useless, since performance in an interview is not indicative on whether an employee is a good fit or not.

a@b is also a valid email address.

It is also a valid SMTP address, assuming you have defined "b" as a FQDN in your DNS.

What we have here is a list of TLDs which have MX records, but an MX record is not even required to send mail to a FQDN. An A record will suffice, for any RFC compliant SMTP server.
If you simply switched to automatic driving, what you would have is fewer cars being driven more often and so being worn more quickly

At the very least, I expect that would be offset by some amount by the fact that automatic cars are going to be driven in a much more efficient and car-friendly manner than they are when a human is operating it with their imperfect motor skills, their ego, their laziness, etc. The way the cars operate would be (or at least could be) algorithmically optimized so that all those little things you're encouraged to do (like pretend there is a glass of water on the dash when you're driving, etc.), actually happen.
They have interesting uses though, because they are effectively a credit card that you don't need a valid billing address for. Allows for fairly anonymous transactions.

Most of the time, you loose the "crispness" of the final image with AA and everything tends to look a little bit blurry. Couple that with fact, that it drops the FPS by quite a bit and over time I got slowly conditioned against AA. However in some games it looks very good. WoW for example has a much better image quality with AA. Of course it also runs with 60 FPS pretty much everywhere.

Native scroll bars are ugly. I agree that if you're going to override them they should function exactly the same. Modern browsers actually do provide a standard way to re-style them. So if you want to be consistent design-wise on older browsers a javascript solution is necessary.

Insurance companies matter a lot, too, though they don't get much coverage in the article. Like others, I don't find the arguments for lower overall usage very persuasive, but I could buy them being significantly safer.

If enough statistical evidence accumulates to demonstrate that these are safer than manually controlled cars, look for the insurance companies to impose a severe cash penalty on driving the car yourself. If the difference is large enough, you might find yourself unable to purchase insurance for a manually controlled vehicle at any price.
Ars Technica did a good series on self-driving cars where they came to many of these conclusions already.

I'm definitely going to try these. maybe then i'll start getting more then 13 views per day on my blog.
Perhaps I'm wrong on what exactly he was getting at, but to apply it to myself I think it's more about wasting time in general. I know I look at HN for inspiration and to stay on top of what is new in my industry. Over time, though, that has turned into a lot of investment (reading/wasting time) with very little return (doing). It reminds me of the question someone asked here the other day about learning how to scale. The best answer was... you learn scaling when your site is over capacity. You can't read that on a site and understand it because the problem is never the same.

I do think it is ridiculous to not research an immediate problem like how to crop a picture in Photoshop.

interesting link, do you think this increased use could go hand in hand with increased efficiency? think about it. if every car drove optimally, they would meet their planned MPG. Now no one gets the listed MPG as they all drive like, well humans.
> Why is that? While techniques like FXAA are needed for deferred rendering due to the order of operations, I don't see why FXAA isn't acceptable on non-deferred renderers.

FXAA is acceptable for the other techniques as well. However, MSAA is, in my opinion, a better technique as it uses supersampling at the edges and is already hardware assisted. FXAA's strength is that it is less expensive than MSAA memory and bandwidth wise. Both are a premium in deferred shading as you are using a 4x RBGA16 texture render target or something close to it :)

> If you have two planes at a right angle to each other, you'd see that in the depth buffer. Imagine you're looking at a line of pixels and you're doing this on each pixel -- you'd look to see if the pixels on either side of the one you're on are trending in opposite directions from the current one, and know it's an edge.

The question is can you get reliable edge detection with less number of texture look-ups on the z-buffer versus the RBG based edge detection?

> As far as I'm aware, all modern graphics cards allow you to render the depth buffer to texture just like the color buffer.

Not quite. You can render the z value to a texture, but that is done in the pixelshader and do not touch the hardware z-buffer used for z-fail/z-pass tests. It is this hardware z-buffer that is inaccessible, as it shares it memory with the stencil buffer which is used for stencil tests. Hence the proprietary format.

> Sure, but there's no reason you can't do post-AA using the RTT depth buffer and your composited color buffer.

See http://msdn.microsoft.com/en-us/library/windows/desktop/bb14...

> All render target surfaces used together must have the same bit depth but can be of different formats, unless the D3DPMISCCAPS_MRTINDEPENDENTBITDEPTHS cap is set.

As you can see, the bit depth restriction means that you would end up with 2x bandwidth usage with the z based edge detector, especially on the older hardware where you do not have the bandwidth to spare. It would be a different case if you can sample the hardware z-buffer.
While I suspect you're right in that the # of miles driven would increase, I suspect that automated hypermiling would more than compensate for it, leading to a net decrease in energy usage.
The passenger-mile invariance would be offset by the selection of different design tradeoffs. For example, most driver cars have far more performance "on tap" than will be used in the entire lifetime of the car.

Such performance is not free. It causes engineering tradeoffs that increase maintenance costs, complexity and of course reduced fuel efficiency.

But it's easier to sell a driver car with some oomph than not.

There will be other design tradeoffs you and I have not thought of (and could not think of) that will add up to further efficiencies.
You arent seeing the bigger picture here. If you choose this level of efficiency, after getting dropped off at work, 'your car' will simply locate the next closest customer. If you want to spend the resources on your own private car or a more available one, more power to you.
Not to mention that driving places, without actually driving people places (ie, back home to drive the wife) effectively doubles the mileage, and thus my gas (or the energy source du jour's) consumption.

edit: Also, to build on the above comment, the benefit of having a car is having the freedom to use it when you want, it's always there. Driverless cars always in motion are basically public transit. Just take the bus/taxi/subway already.
The Wall Street Journal recently fashioned you as a “digital music impresario,” how do you feel about that?

“I didn’t know what it meant. Does that mean I run a carnival? What we do at Apple is very simple: we invent stuff. We make the best personal computers in the world, some of the best software, the best portable MP3/music player, and now we make the best online music store in the world. We just make stuff. So I don’t know what impresario means. We make stuff, put it out there, and people use it.”

Damn, I miss this guy.
Trends of green packaging
Like other green industries such as green food, green cleaning, green cars, green energy, etc, green packaging is becoming more common. Growing number of established suppliers of packaging more environmentally friendly through the sale of a growing range of packaging products. Various ways in which these companies are increasingly environmentally friendly by using materials that are biodegradable and sustainable, the most important thing is encourage companies or individuals reuse or recycle those green packaging.
http://en.wikipedia.org/wiki/Jevons_paradox

As the efficiency with which a resource is used increases, the tendency is to use more of it rather than less.

Concretely, if I don't have to drive the car myself, I wouldn't hesitate to drive anywhere. I'd go to the city every day if I could read on the way, and sleep on the way home.

I wish that were true, but actually playing with SQL for the first hours can teach you much more than 20 articles about InnoDB vs MyISAM, MySQL tuning, Sql vs NoSql, etc...
One gives constructive feedback only if they really care and do not mind spending some time explaining why you think there are flaws that need to be corrected.

Several of the managers in companies have the habit of saying "well done" to top performers with top rating during performance review & have nothing constructive to say. Does that mean they have nothing to improve in current position & they should just vacate the place so their direct report can take his/her place?

As Mark says in the article, it is the difficult path. To take a stance, have a point of view & explain why it is so. The easier option is to say "great work" & just run away. I am learning this more often in areas that are new to me - say in appreciating designs & colors that I am not so good at in web design & so on.

Honest mistake guys, I've listened to almost every episode and had no idea. All the jokes about the Hawaiian shirts and I've been thinking of the wrong person.
But if less people have cars (say every 10 people share a single car), then the energy used to build cars diminishes.
The article might not but I think that it would totally happen.

My assumption here is that there would emerge a big car provider who would provide those cars, similar to how there's only few major car rentals, or how ZipCar is leading in its category or even how Uber emerges as a single taxi-like provider. The economies of scale are very big here.

Given that, some things you have not accounted for:

Higher average utilization per car. I don't know how much commute traffic accounts for total traffic, but by judging rush traffic on 580, it's quite a lot. Most of those people go from the same location (e.g. SF) to the same location (e.g. Mountain View) and today most of them drive alone. Today 4 or 5 of them would be scheduled by an algorithm to use the same car.

Because of that the cars would get re-designed for a higher capacity (at least 8-10 people) or even straight up buses. A big provider would have so much data that they could optimize the hell out of sharing cars.

Similarly, the cars would utilized, on average, much better. Again, a company with enough data could really optimize for a lifetime of a car and they would have economic incentives to do so (unlike a single customer for whom even gathering the necessary data would be cost prohibitive).

Our cars are, without a question, utilized very inefficiently. Someone operating a fleet of tens of thousands of cars would have not only economic incentive but also necessary data and necessary transaction volume to optimize per-car utilization, because for them it would translate directly into large savings.

What's that got to do with anything? Why should driverless cars be expected to last as many years as current cars? If you're only paying for 20% of the car's lifetime cost, then you're not going to mind if it has to be replaced five times more often. In fact, you'll probably like it - that's why anybody ever leases cars.

It's quite reasonable to expect that it will be economical to pay something like 20% more for the drivetrain to make it more durable, but that's not a radical re-design.
Just like he eventually worked out how to produce clean safe operating systems. No wait..
Haven't taken any offense and appreciate the honest dialogue. I haven't said anything or implied anything about lying and I think we agree that these behaviors are on a spectrum.

The point of the post was actually to just underline the importance of sales in our lives - and that everyone needs to sell in order to succeed. Many others have made this point before, which is fine. I believe that "honestly demonstrating its value to a demographic" is a form of selling and that improving the ability to sell will help achieve goals.

I appreciate your feedback. I know that some find my style distasteful and acknowledge that not everyone sees things this way. I will say that U have targeted this series toward people who are closer to the patio11 than used car salesman and this thread will help me adjust my future posts to get my message across better.
As someone who has spent a fair deal of time in the audio world both professionally and independently I'm pretty confused by this post.

The primary reason to oversample in the audio world is two fold:

1) To avoid aliasing, which is a somewhat different issue from graphical aliasing. ADC conversion creates aliases of the primary signal lower in the frequency band. For example if we sample at 40khz we can resolve signals up to 20khz. If the input contains content higher than this frequency it will alias into the pass band.

For example a 24khz tone on the input would appear as a 16 khz tone, a 28khz tone would appear as a 12khz tone, all higher frequency content will mirror around the Nyquist-Shannon point. Now if it were possible to build a "brick wall" filter, that is. completely block anything above the Nyquist-Shannon point and completely pass everything under this point, there would be no issue. But, in practice, this type of filtering isn't possible. As a result if your sampling at 48khz and you want to accurately convert all content up to 20khz you have to play a balancing act. You either provided flat response to 20khz and accept that some aliasing will make it through, or deal with some reduced level(roll off) at the higher end of your desired spectrum and block all audible aliasing.

This is really the primary reason for oversampling for high fidelity content as we can push the anti-aliasing filter well above the audible spectrum, allowing us to get both flat response to 20khz and block all audible aliasing. It should also be said that this issue is becoming less and less and issue as ADC/DACs are now implementing digital filters which can get far closer to the ideal 'brick wall' than is reasonable with analog filtering.

2) At a deeper level, oversampling increases resolution. Note that resolution here means actual resolution, that is bit depth, which is in opposition to the use of the term in the parent post. An example would be modern Sigma-Delta ADC/DACs.

Its common to use a low resolution part, maybe only 1-4 bits and oversample at a higher rate. For example, if your target output is 48khz @ 24 bits, you can use a 20 bit ADC and sample at ~12.28Mhz and downsample (internally within the ADC/DAC, really just averaging) to get your desired output. In practice a part may only operate on 1-4 bits but sample, much, much faster to get the desired resolution.

As for upsampling for the purpose of signal processing, there are a limited number of algorithms where this is useful and upsampling in and of itself introduces issues that have to be dealt with. The reason for upsampling tends to have more to do with processing accuracy limitations created by computation than anything else. For example bi-quad filter coefficients at very low frequency, say 5-8hz can exhaust the available resolution of a 32bit float at 48khz where as it may be completely fine at 192khz. This can be an issue with a sub-sonic filter in a subwoofer for instance.
Seer of the mirror world
I doubt it. How much more efficient do you think automated cars would be? Now think about all the people who will decide to live farther from work because they can work (or play!) on their commute, all the people who will take long overnight road trips while sleeping in the car, all the cars that will drive empty from place to place for various reasons, and most of all the businesses that will all have free automated delivery. I could easily see all that resulting in a 5-10x increase in car-miles driven.

A number of PS3 titles use a technique called morphological anti-aliasing (MLAA) which is more computationally expensive than FXAA but can look better (to art directors and rendering engineers anyways :)) and, because it runs well on the SPUs, it is able to offload the GPU for it to begin on its batch of work.
