1) In trying to find out if, generically, there is a causal effect between salt intake and blood pressure, it is sensible to select a healthy population. The hypothesis being tested is "In good working condition, the human body maintains correct NaCl levels". You do not want to test people with faulty metabolism, because they are outside the scope.

2) See explanation in number 1.

3) I have not read the original paper, but the news article makes no mention of such inference.

I have to say that I think the premise that the human body must be excellent at maintaining NaCl levels perfect is sound. Sodium and chlorine are very active chemical elements. Having them in wrong levels probably throws every chemical reaction in the body out of whack. If I were to design a chemical machine that used NaCl, keeping the correct level would be a primary control. Evolution tends to get these things right, so our bodies probably do have excellent control mechanisms for this balance.
> All existing apps will be rendered into the current 320x568 frame buffer and scaled up. It's really no different to an iPhone app running on an iPad in that respect.

I don't think it quite works that way. In the past, your iPhone app was designed to run on iPhone only and it upscaled if you attempt to run it on iPad and the OS knew it had to do this due to a checkbox setting in xCode.

Nowadays, most apps are universal and runs on any device by adjust the output according to device resolution and given scale factor. Basically the scaling is handle internally by the program and not by the OS as described above. In theory, your app should be future proof if you did this correctly.

That said, you need HD Retina graphics so that your code avoids upscaling images. Beyond that, everything else such as fonts are not upscaled but drawn to scale.
There are even fewer regulations preventing Uber drivers from declining a fare based on location - or race, or gender, or they don't like your sports team, or anything.

This is because Martin Matuška of FreeBSD has been focused on upstreaming changes made in FreeBSD's ZFS port into Illumos. At present, the ZFSOnLinux project has had no one dedicated to that task and code changes mostly flow from Illumos to Linux. This is starting to change. A small change went upstream to Illumos earlier this year and more should follow in the future.

That being said, there are commonalities between Illumos and FreeBSD that make it easier for the FreeBSD ZFS developers to collaborate with their Illumos counterparts:

1. FreeBSD and Illumos have large kernel stacks (4 pages and 6 pages respectively) while Linux's kernel stacks are limited to 2 pages.

2. In-kernel virtual memory is well supported in FreeBSD and Illumos while Linux's in-kernel virtual memory is crippled for philosophical reasons.

3. FreeBSD and Illumos have both the kernel and userland in the same tree. FreeBSD even maintained Illumos' directory structure in its import of the code while ZoL's project lead decided to refactor it to be more consistent with Linux.

Difficulties caused by these differences should go away changes made in ZoL to improve code portability are sent back to Illumos.
> They're all propagated from cuttings, hence they are genetically identical. Which means the skins are the same as they were before, and the flesh as is bitter (or otherwise) as it was before, etc.

No, it actually doesn't mean that. First, genetics aren't the only determinants of those features; environmental factors, growing, shipping, and storage conditions, etc., all play a role.

Second, propagation by cutting doesn't mean they are genetically identical, because mutations still occur and are an important source of variability, and not all of them result in different branding.
A theory as to why Apple's live video stream was a complete bust
I copy a lot of music to my phone - but it just kind of automatically appears playable there when I buy it - and I can "download" it onto the iPhone by clicking on the cloud icon. Presumably some combination of iCloud / iTunes match takes care of that for me in the background.

I just realized the one thing that I am missing, that I've heard can be done with iTunes, is the ability to delete an album. iPhone only lets you delete one song at a time - which is painful if you have a lower capacity iPhone.

Good reason to buy a 128 GB iPhone and just never worry about it again.

Favorite part of those Blinn books is the revelation that NTSC can be understood as originating as a time division multiplex of RGB. Intriguing given the preoccupation in some circles with the supposedly purely analog nature of TV.

iTunes Match + iCloud syncs your music automatically. Kind of like Photostream for music.

Photostream, after a rocky few initial months, has been awesome for the last year+ I hope it works as well with the new Photos apps as it has with Aperture.
Usually the token kept in memory is one distributed by the application and is not that which the services send back.

What is application in that sentence? The API?

Isn't that what this lib does?

A client-side Javascript SDK for authenticating with OAuth2 web services and querying their REST API's.

- I assume the API issues the token
- This lib receives it and uses it for subsequent calls
- The token is destroyed when browser session is closed.

I'm going to have to disagree with you on this one. I come from the "Apple Capital of the World" and it's all about local fruit. We ship out our fruit everywhere in the world, and it's not going to be anywhere near as good when it gets to you as it was when I ate it. We make the best apples hands down, but nothing compares to your local fruit if you are fortunate enough to have good orchards.

Basically what I'm getting at is that American fruit that's taken care of on the way to your mouth is great. If your local fruit tastes like this, then it's just not good fruit.

Merged LTC Doge Mining TODAY and Multipool Launches New Merged Mining Pool [video]
For so much people, the status quo is not food or fast food. Soylent is significantly better for them. I'm not saying eating "real" food isn't a better option but not everyone have that luxury for a lunch.
My children react this way to precisely three things in their life: TV, iPads, the stuffed toys they've decided they "need" to go to sleep. Everything else they seem to pick up on a whim and only react badly when the other tries to tear it from their hands - yet 2 minutes later and they've forgotten that toy and moved on to the next.

Electronics, however, they're glued to from the second they get their hands on them until they're eventually taken from them because something else must take priority - such as bed time, school or some family engagement (i.e. meal times are always taken together as a family - electronics free).

I find also that their interaction with electronics seem to evoke an attitude of entitlement to do whatever they want. For example, when bed time rolls around, if they've had electronics leading up to bed time, all hell breaks loose when bedtime is announced... despite 30 minute, 15 minute and 5 minute warnings ahead of the call for bed. When the electronics are removed so they can begin the bed time routine, they both have full fledged tantrums which don't happen if they're curbed from having any electronics or TV and if we spend time say reading with them or letting them play independently away from electronics. It's the same if we need to leave the house to go get groceries or visit relatives.
It's not technical like the many posted here but as the name suggests, it's quite interesting:

At any rate, forbidding is not the solution. It only cures the symptoms, not their underlying cause. Better to learn to your kids to enjoy the good things in life responsibly.

And even if your kids play more than you would like, so what? As long as it does not detract from other aspects, it should be fine. Talk with them about it. It seems to me that the best way to make responsible adults is to treat children like responsible adults to begin with (with some caveats, of course).

If any activity starts to become detrimental, there's the time to start acting... Not on a vaguely defined fear that it might lead to something bad. That's trying to exert a level of control on another being's life that simply cannot be achieved, and it often backfires badly later in life, when the activity becomes available without imposed restrictions.

> Do people complain like this about Kobo and Kindle readers automatically downloading new books?

Yes. Partly because all an ereader really needs to do is to display books, and Kobo's fucking awful software makes it nearly impossible[1] to do so unless you have a working internet connection on the host computer, and the Kobo, and you upgrade the Kobo before using it, and you download and install software on the host computer, and you set up an account. Walled gardens are bad, but they're even worse when I have to spend so much time laying the bricks.

And the Kobo is one of the better devices - everything on an SD card so you can back it up and tinker away.

[1] you can use a bit of SQL to persuade the Kobo to not need all the online stuff. How many Kobo readers know what SQL is?
Kinda yes, but it isn't free.

If you pay for iTunes Match, import all of your non-iTunes music into iTunes, Apple will store a DRM-free AAC file (256 kbit/s) in the "cloud" which you can play/import directly onto your mobile devices (without sync/tether).

You only have to pay for iTunes Match when you have new music to import. Once imported it is available "forever."

PS - I ironically used this to escape the Apple ecosystem. You can use it to strip DRM from old Apple DRM-ed music. You import it using match, and it converts it from an AAC-DRM track to an AAC DRM-free one and ups the quality from 128 to 256 Kbit/s.
Just a note, obviously an exaggerated "review" meant to be funny, not serious. There were minor problems with gas that have been fixed in the new recipes. (Note the date on this.)

> Prosecute crimes against inmates

That's already the official policy.

So how do you make it real?

Short of removing the executive branch's monopoly on criminal prosecution, I don't see how it can be done, and there's all kinds of problems doing that (for one thing, unless you also abandon protections against double jeopardy, you invite sham prosecutions to protect the guilty.)
I disagree with the premise that this line of thinking is somehow exclusive or original to tech CEO's though. At least in my own experience, most parents I know can afford tech, but limit it in some way. Unfettered access to tech for young children seems to be the exception, rather than the rule, in my experience.
Placed in the same circumstances, most adult would not react much better. That is not to say there is not something about childhood that might explain the behavior, but I would avoid immediately jumping to that explanation. It's much too convenient, and has been, is still, being abused in the way we treat teenagers (see the pg essays in which he talks of kids and suburbs -- don't remember which one it was).
In practice, an addiction is merely a habit that is not wanted, whether by the self or others. We acknowledge that gambling can be an addiction, yet an addiction to a game or to internet browsing is taken much less seriously.
I'm reminded of the "sugar causes hyperactivity" hysteria, which also required parents to ignore the evidence in favour of targeting something that was seen as culturally low value.

Yes. They are great for certain sized homes. They can cool off a house pretty quickly in the evening provided it's cool outside. Installed with whirlybirds on the roof and it also provides the benefit of pushing out the blanket of hot air in your attic to keep temps down... The only cons are how loud it is and the fact that it's uninsullated.
For someone who built his fame and fortune on technology, Steve Jobs was surprisingly anti-tech and anti-learning in many ways.

Another example of this is that he didn't trust traditional medicine and he decided to fight his then benign cancer with some unproven fruit based diet. One year later, his cancer had progressed to the point of being terminal and even traditional medicine could no longer save him then.

A little weak in the heights, and no hi-fi (no exaggerated subs). But really good for the money. Also available in half closed. With this clear and neutral sound you will begin to hear youtube compression and bad mixes though :) Also look for the ohms, they need quite some power.

If you prefer a more roomy sound I'd go for studio AKGs, but for a clean sound it might need a little more than your budget here.

Yes, per 21656 (which, incidentally, you didn't cite) a bicyclist blocking 5 or more cars must pull to the side and let them pass as soon as they are safely able to do so - just like anything else on the road (and damn it, I've encountered enough drivers who seem unaware of this).

That is neither a minimum speed nor a general injunction against impeding the flow of traffic.
Personally, I find most tech podcasts annoying. The ones I still follow are the Java Posse, Hanselminutes and SE Radio.
As an American who's almost 40 and remembers grocery shopping with my mom as a young child, there were typically only three common apple varieties available: red delicious, golden/yellow delicious, and granny smith. That's it.

Nowadays, even at my crappy Food Lion, I can find those three, plus usually 2-3 additional. At local higher end groceries, I can find 8-10.

At my local farmers' market, I can find 20-30 (when they're in season).

My personal favorites are Honeycrisp, Jonagold, and Pink Lady, but since Jonagolds aren't common in my state and Honeycrisps are a restricted patent and very expensive, we usually buy gala, fuji, and sometimes braeburn.
I very much adore ZoL. Thank you for your efforts. Everything critical works and works very well.

While I get the sense that this is probably not the focus of your own work, do you have any thoughts on the maturity of the "share" facilities when using ZoL, and as the project matures will these become more of a priority? These are "nice to have" features that are obviously of relatively low importance.

You mentioned shareiscsi is unimplemented, but I also find that its friends sharenfs and especially sharesmb have some rough edges as well. When I moved a pool from an OI machine to a Linux machine, I had to massage all of my share attributes to make them function.

From what I understand, Google's self driving car is heavily based around the lidar sensor. The lidar sensor is used to image immediate surroundings in 3D in real time. Rain, snow and fog interfere with the laser pulses sent out by the lidar sensor, which basically renders the self driving system blind.
> What I've seen with my kids (under 10) is when they get an hour of phone or tablet, after they have to give it up again, they become very aggressive and behave in a manner which is comparable to someone with a chemical addiction

This has nothing to do with addiction and everything to do with parental education. You will get the same kind of reaction if you take away a toy that a child is currently having fun with, regardless of whether it's a tablet or not (I bet our parents were having similar concerns decades ago when they turned off the TV on us).

A simple talk such as "You can play with it again tomorrow but if you act like this again when I take it away, they you will never get to play with it again" did wonder with my kids.
Could it be that they are aggressive not because of the context switch but the fact that you are forcing it on them? I know I sure as hell hated when my parents told me to stop playing video games but had no problem quitting while I was in the middle of playing if something more interesting was happening like my friends showing up at my house.
Not doubting you, but I would love to see the methods to make this happen. Is your concern from a 3rd party script included on the page?

From my experience memory is safe between origins in the same way cookies are. And it is the dev's responsibility to not do something stupid with the token like window.FacebookToken = OAuthToken;. But that holds for traditional session cookies as well.
1. I am not aware of this specific issue. However, I am aware of an issue involving slow pool import with large numbers of zvols. Delphix has developed a fix for it that implements prefix. It should be merged into various Open ZFS platforms soon. It could resolve the problem that you describe.

2. Matthew Ahrens' synctask rewrite fixed this in Open ZFS. It took a while for the fix to propagate to tagged releases, but all Open ZFS platforms should now have it. ZoL gained it with the 0.6.3 release. Here is a link to a page with links to the commits that added this to each platform as well as the months in which the were added:

http://open-zfs.org/wiki/Features#synctask_rewrite
I use ZFS on a dual-boot Mac to cross-mount the Linux partitions on OS X. ZFS is pretty much the only file system that allows this: The XFS OSXFUSE plugin is read-only, the ext plugin only supports ext2 with unstable write support and BtrFS can't be mounted on OS X at all.

The ZoL-derived OpenZFSonOSX port inherits ZoL's maturity, runs in kernel space and the OS X integration is really nice (Notification Center integration in ZED, custom icons, etc).

100% is very feasible, even without going the Earthship route. Mostly it has to do with extra insulation but there are a couple other techniques that help. The reason more houses aren't like this is because it adds $10-20k to construction costs so developers don't bother.
