You're missing the point: that layer is mostly there to ensure that we
don't foul up the kernel's readahead recognition for sequential fetches.
It's nice that Linux doesn't care, but Linux is not the only platform
we worry about.

Part of the problem is that many power users have no other option.

Many of us can't use Windows because we need our primary machine to be _nix for various reasons (because our servers are Linux based, because we're used to the commands/tools from the _nix ecosystem, because configurations etc are easier to to understand and work with in the _nix ecosystem, etc).

And many of us can't use Linux because there's no laptop that comes close to the power, portability, ease-of-use (think wifi, power options), screen, etc of Macbook Pro et al. Add to that the fact that many apps we need to use (Illustrator, Photoshop, Sketch, etc) don't run on Linux natively.

So, even if you ignore the fact that the non-power-user is a much bigger market, there's no reason for Apple to focus heavily on power-users because we aren't going to go anywhere else.
So, your concerns would be alleviated entirely by a compulsory licensing scheme?

Incidentally, are you aware that 100% completely non-GMO plants are subject to an IP regimen called plant breeder's rights and have been for decades?

> "Mouse-over" for more info is not meaningful for touchscreens. So icons can't have explanations.

I suspect the period of not having a decent UI for surfacing alt-text (on web) or equivalent help for native apps on mobile devices is probably not going to extend long into the future. I don't know what the UI convention will be (gaze tracking? light-touch with pressure sensitive screens? some gesture?). Touch UIs are (despite being ubiquitous with the explosion of the last decade) still relatively immature.
I guessed, but didn't mention it since it seemed somewhat unlikely that you would have more or better data than Facebook/Google/Etc.
Just had to get all that judgement off your chest, huh?
Great quote. I call it corruption, self-preservation that hurts the masses, and status quo thinking. Technology is going to hopefully disrupt all of this.
Not only are Zynga's non-monitized "close dialog" buttons tiny little lower case "x"'s, but the mouse sensitive target area is actually SMALLER than the visually apparent target size, so you have to thread the needle to get through without paying! It's like you're trying to blow up the Death Star, but R2D2's knocked out and The Force isn't with you.

What the sibling comment said about Dark Side of A/B testing always applies at Zynga, to the millionth power.
I hate to be negative but I am slowly beginning to believe they're completely loosing their minds at Reddit. Not long ago they had this epiphany re turning links into affiliate links. Now they allow companies to purchase user posts in what appears to be a rather clumsy process which eventually may or may not lead to an ad with a highly questionable ROI.

Otoh, (and here I am not being sarcastic) if you try these kind of mad ideas for long enough you may really find the ultimate monetizing strategy one day. Who knows...
I don't want to be pessimistic, but making money by milking profits out of existing products while loosing market shares and not opening successful busines lines is exactly the sign of failing big companies. Blackberry was making profit until very late.

I see signs of decline on everything apple does, from failing products ( watch ), to failing software ( xcode, macos having the same network connectivity issues for years and not releasing anything new for years, ios still relying on decade old software stack and an aging cocoa framework).

The only true technological success i've seen from apple recently is what they're doing with swift, and it's maybe not a coincidence that it was aimed at being a cross platform, community driven technology.
I saw this helmet for the first time about 3 years ago at a hardware meetup in SF. I thought it was a sure thing at the time, pretty surprised that it's gone belly up. It's unfortunate.
That's basically the size of A4 writing paper (slightly larger, but a pad of paper on a clip board would be the same dimensions). I haven't tried it, but I'd assume it is quite nice for note taking/sketching etc.

Oh, I thought you were referring to something on Let's Encrypt's end. For "real" internal names, internal CAs sound like the best option, and would work just fine with what browsers call "powerful features." For anything else, Let's Encrypt would work.

Yours is a definition of contrast, but not the one used in design or vision science [1, 2], where contrast is defined as a difference in luminance or color between regions of an image that makes objects and textures visible. If an image has no contrast, it is a solid patch. If an image has low contrast, the brightest or most colorful regions are not too different from the other regions, as if seen through a dense fog. If an image has high contrast, the brightest or most colorful regions are quite different from the other regions.

What’s New with Hybrid Memory Cube (HMC)
Dell sells an XPS laptop with Ubuntu Linux installed out of the box, then you have System 76 and other companies that focus on selling you Linux-only devices. I guess your main issue after that is application compatibility. I use a VM to run Visual Studio, which is the only non-Linux application I need, but I make due with Mono Develop to some extent.
Here we're talking specifically about "visual contrast", which has a meaning in perception slightly different than the common usage of "contrast".

Visual contrast is measured on a spectrum that starts at zero and goes up from there - a box of a particular color inside a box of the same color would have no contrast, but if there is any difference in the color values then there is at least some visual contrast.

Wikipedia isn't a great source for definitions, but has a reasonably thorough take on this https://en.wikipedia.org/wiki/Contrast_(vision), going into the details of contrast sensitivity, which deals with almost-imperceptible levels of contrast.
As a rider myself I'm not surprised.

The product seemed very gimmicky to me. I also would be very concerned how safe the helmet is compared to a snell approved Arai Signet-Q
Given that almost every web dev's assumption is that TLS encrypts URL parameters, yes it does. Do search parameters in GET requests going across the wire in cleartext not count as possibly sensitive information to you or something?
Luckily for you, Windows 10 will support Ubuntu Bash natively (as part of the anniversary update).

This is really well done, kudos! It actually feels a little like I'm learning by doing here as the design firms up in place as I proceed. Very cool idea!
Hardware startups are incredibly challenging and capital intensive. It seems they ran into the classic cash flow problem and didn't have a coherent enough leadership situation to follow through with the next round/acquisition.
For what is it excellent? What do you use it for?

To me it has weirdly uncomfortable ergonomics, and it's still nothing more than a jumbo iPhone. I have long tried to like iPad but I find no use for it.
Yeah I guess that's one way to put it (little different but kindof).
What Do Engineers Think of Trump’s Energy Plan?
I usually roll my eyes at all the hate people always find for Microsoft in nearly every decision they make and every thing they release into the market. I upgraded my gaming desktop to Windows 8 the day it came out, and I upgraded to Windows 10 when it came out. I've never really had too many problems.

But everything new they release and everything I use from them makes me thankful I mostly use Apple products. I don't have to worry about the new version of Windows destroying my computer or forcing itself upon me, and I especially love knowing that my computer will not reboot itself unexpectedly at night due to security updates. I'm glad I have products made by a company that knows what it is and what it does, that focuses on stability and polish. A company that doesn't flap back and forth between consumer and enterprise computing, discontinuing devices and services as fast as they can create them. Maybe I'm still sore from the loss of my Zune, or my Windows Phone, or my TechNet subscription.

I didn't start using Macs with the Lisa, or System 7, or even when OS X was released; I'm fairly new. This is only my second Mac. But I used Windows for years, and every time I hear someone say "I'm leaving Apple for Microsoft because Apple has lost their way", what I actually hear is "I'm making a symbolic statement and I don't actually care what the repercussions are." Because if anyone thinks Windows is more stable, more polished, more developer friendly, or has machines with a better build quality, I have to say... you're gonna be surprised.

Maybe Apple isn't what it used to be. But it still seems a damn sight better than Windows, in almost every regard.
Yes, the log is static. It only contains the subject name if the certificate.

But there's little to fear from exposing internal domain names. DNS names are more or public knowledge - they are transmitted unencrypted, end up in plenty of caches etc. Attackers can probably brute force it or the PTR records anyway.
This is one good simple explanation.

=) A valid question! I am developing (yet another) fractal viewer for the browser. It's called FractalViewer, and is available from GitHub [1]. I am working on allowing it to zoom past the limit of about 10^(-13). The specific FractalViewer development issue is [2].

Why bother at all? I am very frustrated that there currently is no fractal viewer for the browser that can do a truly deep zoom. See a list I compiled on web-based fractal viewers [3].

Maybe someone can correct me, and point to a JavaScript based fractal viewer that can do really deep zooms...

I've been using Macs for years and recently switched to Windows 10 as my primary dev device. Bash on Windows is almost as good as running on a Linux kernel, and it's not finished yet. Truly the only thing I miss is Sketch.

Recent changes have made Windows very approachable/usable for a Linux and Mac power user.
In the last months, I have started to teach myself the basics of CS besides my full-time job. I'd appreciate any comments and recommendations on how to structure the learning path ahead most efficiently. It would be also interesting to hear about your experiences, especially if you have taught yourself how to program.
The company that nearly acquired Skully before they apparently "messed up" (LeSports) just got $1.2 billion in capital so I don't think you can say easy money has stopped floating around for AR startups. This headline could just have easily been that the company was getting bought out.

Skully just couldn't hit their targets for the 2nd round. Especially with the founder getting dramatically booted out and Intel Capital Partners is quoted in this article as still being actively involved until the very end - they clearly had greater problems than access to capital.

So I'm not sure this story backs up your narrative very well.

Clearly, any kind of always-on automation that is responsible for braking, must be able to gauge the strength and importance of obstacles. For example, driving through that grass slowly and carefully, is ok. If there is a wire hanging across a road, then that is definitely something to stop for.

I'm thinking that a very good visual AI would be necessary to make distinctions like this; radar won't even see a wire, I don't think, and to lidar, it would look a lot like the grass. A touch-sensitive coating on the car would probably be a good idea too, so that the car can tell when if it is starting to scratch its paint on what it thought was an insignificant obstacle, like a branch.

Simply not looking at obstacles in one area because of the difficulty of rejecting false positives is a terrible idea, and demonstrates that that AI is not ready to drive.
Complications of measuring time
I'm not so optimistic about a positive or even neutral response. I say this as a rabid transhumanist who desperately wants to see BCI and WBE come to reality.

My fear is that, an "enhanced" human will significantly outperform it's peers and thus will gain advantage in all aspects of life, that is the point after all. Those advantages will be seen as unearned and thus the "losers" will become jaded and blame the technology - or rather the person's access to it. Someone who was conceived in vitro doesn't pose a threat to it's peers from the perspective of abilities by virtue of being in vitro.

Just like you see jealously now for disparities in abilities, I worry it will be magnified once people start upgrading.

That's without even getting into the "who can afford to upgrade" part of it.

Well, for me being based on pure C instead of the OO interfaces of other APIs it isn't something that makes me wish to use it.

I rather use APIs that embrace OO, offer math, font handling, texture and mesh APIs as part of SDKs instead of forcing developers to play Lego with libraries offered on the wild.

> Khronos isn't a company—it's a standards body. As NVIDIA is a member of Khronos, "Khronos" did bother to create a C++ API.

I guess that is one way of selling the story.
They might want to put an overpass, separation rails, reflective distance markers around the entrances/exits, and generally do something about road safety.

In principal absolutely, but Reddit is portable and python which is probably significantly more useful in practice:

Running a VM means I get the best of both Linux and Windows. I also get the worst of both Linux and Windows. I don't think OSX has gotten bad enough for me to go that route and be forced to manage two operating systems.
This is a significant feat. Apple's $6b in revenue from services beats Facebook's last reported quarter for the entire company.
That would probably put them on the first team to do this :)
More evidence that even top researchers routinely misinterpret p-values
Judging by many of the comments I see here, especially in threads about products that do target power users, power users are so difficult to please that targeting them is probably a waste of time and money.
I fondly remember one of Microsoft's original "Dynamic HTML and JavaScript" demos:

Two buttons. One labeled "Our Web Site". The other labeled "Our Competitor's Web Site".

Whenever you point at "Our Competitor's Web Site", it quickly slides out from under your cursor so you can't click on it.

Whenever you stop moving your cursor, "Our Web Site" smoothly slides under your cursor so it's convenient to press.
Overhead road signs have a huge highly clearance (think of those tall trucks). I don't understand why they didn't check for clearance of 10 feet.

We're talking about considering suicide! Going through with it is a completely different matter, due to very many factors, some outlined in the OP, another sometimes being physically unable to do it...

> I've seen people with chronic pain (including long-term fatal cases) that are not just "despair and suffering". Including people who have dreams and follow them (creative work etc) despite the pain.

Without any kind of pain management? With severe, chronic pain?

Well, what I witnessed may have been outliers, but once you hear a person you care for begging to "please, just make it stop" every time she was able to actually articulate some words instead of screaming in pain... that leaves a mark.

What I'm saying is that there is - possibly very different for different people - a threshold of (pain-intensity times pain-time-length) above which everyone will be considering suicide. That the people you know are below such threshold doesn't mean it's not there. Having seen people way above it I really can't accept people telling me that they'd rather "live with the pain". What they mean is they'd rather live with bearable pain, which is OK; however, there is such a thing as an unbearable pain and I don't believe there is anyone who'd like to live with it.
Why? #000000 is meant to be pitch black, as black as being locked in a room without windows or light. #ffffff is meant to be as light as looking right into the sun itself, blindingly bright. (And my monitor accomplishes quite something like that).

So if I want to be able to play games tweaked for this wide spectrum, and read text, I either just can't, or have to hope websites use grey-on-grey.
This one had been percolating in my head for quite a while.
You're wasting your breath. REST zealots will never be convinced that anything other than the magic four of GET / PUT / POST / DELETE is necessary.

It's like someone advocating writing all software should be written in Brainfuck, because the cognitive load of remembering eight operators is so much easier than learning all these keywords and syntax and runtime libraries that come in other languages. Except whereas our imagined Brainfuck advocate would be rightly ignored, REST has somehow become the fucking dominating paradigm of our industry.

The idea that reduced complexity in one area might trade off with much greater complexity in another simply does not wash with these people. They have a resource & verb shaped hammer, and they are going to use it to batter each and every API into some kind of nail shape, no matter the effort it takes and the carnage that ensues.

I think Apple has it's issues, but isn't this textbook Innovator's Dilemma? Newer vertical looks small compared to established vertical, thus dismissed.

$400 every two years (assuming 50% profit per phone!) is just $17/month. If Apple can convince you to pay for 2 or 3 of its services, then they're gold.

Where does the "11 years" comment come from though? How do you figure that?
I'm not saying it's infeasible technologically. I'm saying it's possibly a terrible idea to have brakes auto-engage upon failure of the power system.
I think people miss the purpose of icons. To be effective, they need to be distinguishable and memorable so that you can find them when needed. If I need to find something that I'm not familiar with, I'm more likely to use a text label to figure it out than to try to guess by the picture. An ideal icon would have a lot in common with an ideal logo.

The current trends are somewhat troubling. Removing color makes an icon less distinguishable, and changing icons yearly makes them less memorable. The reason the floppy disk icon is still useful so many years after it stopped being relevant is because it hasn't changed.

I do miss the richness of imagery that skeumorphism provided, I find it more visually appealing than the abstract flat look. I realize this is a matter of opinion though. How ironic that as enhanced displays allow for more realistic renditions than ever, the trend is to move away from realism.
If you don't mind doubling your turnover....
Yes. Most of the unnecessary complexity has just been moved from bad APIs with XML configuration to bad APIs with runtime scoped annotations, code generation and byte code manipulation. It's still a huge mess.
And yet LE added IPv6 support a mere 2.5 months after it left Beta. It's not that bad!

I really hate this association of aircraft and car autopilots.

Aircraft operate in essentially empty space, and barring major mechanical failure the pilots typically have tens of seconds up to many minutes to act to avoid disaster. In a car you often have less than a second to react, and certainly never more than 4-5.

Aircraft hardware and software is tested, retested, tested again, and certified. Auto hardware and software is pushed out the door with reckless disregard for reliability.

There is really no comparison.
