That's a bit overstated. But mechanical_fish is right that that my own choice of words could have been more tactful. That's why I changed "Syntax correction" to "Syntax tip" in the GP.

It isn't about English, but getting closer to the way programmers think. Most people don't think b.substring(1) natively any more than a musician would think "Da Capo al Coda". There are good parts of course; b[1:] is about as natural as ♩. for notation.
>So? Once you add feedback (blood tests, medical supervision) to your dietary "loop", these mistakes have the potential to sort themselves out.

except the ones that take years to present, and are things that we don't necessarily understand well yet.

>Some people's health is at risk simply by maintaining their normal eating habits.

Just because people have bad nutritional habits doesn't mean that soylent is the answer. Surely better education and a redistribution of farm subsidies to nudge people towards healthier lifestyles is a more complete and safe route?

But yeah, soylent does allow people to feel that sense of achievement of playing armchair scientists.

>What ethical problem? Don't participate if you don't like the terms. It is not as though the stuff is being tested on schoolchildren, or anyone who is unwilling.

There is an assumption amongst educated and knowledgeable people that others are equally so. Some of the people who participate in the soylent trials wont be knowledgeable enough to be able to make good meaningful decisions about what they put in their bodies.

Sure, it's their choice, hell they can suck lead paint off walls if that's their thing, but the whole point of food and supplement laws and safety regs is to prevent people doing themselves harm, particularly when they are not themselves cognisant of the harm they might do.

Add to that the hubris of those who know just enough to be dangerous, but not enough to be cautious, and something is going to go terribly wrong eventually. Perhaps not for the originator of the idea, but certainly one or several of the participants.
That's distorting my words and ignoring the effects of polarization. I said I agreed with education. What I have a problem with is the black/white attitude almost every nutrition course has. It was more of a plea for people to cooperate and work together rather than the appeal to ignorance that you seem to be accusing me of. I only wrote the comment so that other learners can be a bit more open minded about the current state of understanding before taking everything they learn in nutrition books/courses at face value.

Trying to paint my nuanced argument in such a bleak light is exactly the type of needless polarization I'm frustrated with.
When I saw Ruslan Kogan listed at the top, I thought the story was about him ... same guy who launched the IE tax publicity stunt - got to wonder if this is more of the same.
I concur with some of the other posters in that automated application vulnerability detection is far from flawless (Heh.....far indeed.)

But that's not to say they aren't using them already. I used to perform high-level security audits of networks. For our cursory app testing, we used:

- Application Testing: HP Web Inspect
https://download.hpsmartupdate.com/webinspect/

- Database/Backend: AppDetective

Automated tools won't, by themselves, ensure you're bulletproof. But they do use them.
The folks at the google group or IRC channel are super helpful. Ask there and you will usually get an answer fairly quick.
Exactly. This is why more companies should follow Gumroad's lead: they let you send out a link with the code, but don't display the coupon field in your checkout form.
No, it specifically says it's tied to the grid for backup power. Section 4.3.
> I hope that the media keeps focusing on the issues detailed by the whistleblowing, rather than the story of said whistleblowing.

Of course, completely agree.

But there is a value in looking at people and using stories and those people's outlooks as our own role models for the future.
Ha - came here to say the same. You know where he should build it? Austin. Austin is IDEAL for him - he can build a small mockup, then build out to Dallas. The next station would then go to Houston - and he'd be able to have one "hub". Next up: New Orleans (500mi away). Then you've got all these other markets - Denver is 900mi away, Albuquerque is 700mi, Nashville is 850mi... If it's optimized at <1000mi, Austin is perfect.
not sure how long ago you tried it out, but ansible has an ec2 inventory script bundled along with it, that you can use instead of maintaining static manifests. This script plugs into the AWS API to get you a list of instances and metadata. Along with that, comes all the goodness of tags and pattern matching, so you can do stuff like tag_Name_DB*:&tag_type_slave to select all database slaves (if you had tags called "Name" and "type" for example)
Good comment, why is this greyed out?

Interesting new addition from AWS. Directly competing with some features from Urban Airship or Parse.
I will have to dig into the code/library they provide since right now for a cross platform app of mine I used my own server (+DB) for iOS, and Parse for Android, but was getting ready to switch iOS on Parse.

One of the main thing that bug me with Parse -and I believe it is still the same: they implemented their own Android service to watch for notification coming in, when I will prefer to have my app use the local native notification system... More work for them since it require different integration on Android and Device like Kindle Fire, but better from a user point of view.

Anyway competitions in that space is good
the very point of this is to lose some the old painful browsers (IE6/7/8) to make code much better. almost all work in cross-browser stuff is IE6-8. think of jQuery mainly as a bugfix for old IE's.
Nit Improves Your Git Workflow.
I thought the whole point was to be able to access a DOM element hierarchy as an object hierarchy? My point is that this convenience comes at a cost, and so I would also not use jQuery in that way. Conservative targeting of selectors negates the very cool benefits of this library, at least for my use.
What we do as an e-commerce provider is use the label 'Gift Voucher'. This reduces the drop off considerably as customers assume that this is something that would have been sent to them already.

West Oakland is 10 minutes from downtown SF (Embarcadero station, nearest to the HSR terminal) by BART, and you can take any eastbound train, so you rarely have to wait more than 2-3 minutes during the day to catch one. The area is already set up for rail, and land is relatively cheap. It's a fantastic location for it. The only reasons to go to SF proper are politics and pride.

Interesting news about performance tests in <4. I didn't realize that, I'll check them out.

The eval problem is as follows (typically if you have to eval something in a gem):

before_save :bar
..
end

Foo.class_eval do
# I want to remove before_save callback here without having to redefine it.

before_save :bar
...
def bar
return
end
end

It's not a big deal, just adds clutter. Thanks again!

I was thinking about what would a cheap scale demo still be useful for. If you built one out of 2 foot plastic pipe, you might still be able to have a market for parcel delivery systems and therefore make your money back off the prototype investment before you make a bigger one. Linking some hospitals would be a good starting point maybe.

> nutrients, only some of which are known about

Well -- you win by default. His mixture doesn't provide unknown nutrients that can't be identified or tested for... I will call them "god nutrients" or "magic nutrients"... take your pick... that is an insane standard to hold anyone too.

How can I ensure I get my daily allowance of "magic nutrients" via my normal diet... now I am worried. Do you have can full of "magic nutrients" that I can use to supplement my diet?

Any expert who tells me there is a "magic nutrient" that can't be tested for and isn't known (then how do they know it exists?) about... well... I won't be taking a lot of advice from them, I will stick to my trusted palm reader.
I do not consider Firefox inferior to Chrome because of this, instead I consider Firefox superior to Chrome for this very reason. With 6 tabs open, Chromium is using 1.6GB of RAM, while I can browse forever in Firefox until it reaches that kind of memory consumption.

This particular implementation wouldn't actually work. Anyone can send BTC to any address, so it would be easy to poison the well.

You could easily have software that would automatically turn over to the government any coins sent from addresses that are not registered. It's like if you found a briefcase full of money: you'd turn it over to the police (or maybe you wouldn't, but that's what you should do). With software, it could just be automatic.

If you refuse to run software that does this, or you don't turn over coins received from blacklisted sources within some period of time, you get blacklisted.

The node-inspired `http-browserify` is my favorite; really nice, sane syntax for doing ajax requests that you can mix with client-side streams and transforms to do really advanced things with code that is clear and readable.

Airplanes leak so much air that a couple more half-inch holes would not affect overall integrity. Most control systems are implemented with redundancy, so taking out a control point would just failover to a backup. Occupants aside, there little such damage could do to an airplane; noting the occupants, worst case is a couple casualties, not loss of everyone on board. And, of course, you could simply choose to not take off.

As mhandley noted, Hyperloop might be more susceptible, as the concern is more like your airplane flying an inch off the ground and hitting a stationary large brick.

...which reminds me of an old analogy: Back when large-capacity (ooh! 10MB!) hard drives were becoming common, I recall hearing the comparison that the read head was akin to a 747 traveling Mach 3 just 1 inch off the ground. Perhaps Elon wondered how this might work in real life, and so came up with Hyperloop.
If you insist of using politically biased terms like "steal" for it, conversely your opponents can just as easily justify reaching for Proudhon and his "property is theft".
You said it may differ elsewhere — I was providing a more general view of what I would expect in Europe.

WiFi varies a lot from country to country — some places you're lucky to get it on any train, others it's becoming coming common on even regional trains; seats on a lot of the older ICE2 sets were really quite terrible prior to their recent refurbishment, and a lot of IC trains in Germany had far better seats; electrical outlets differ from place to place — the TGV Duplex will never have power outlets at all seats, for example, despite being a high speed train, as there simply isn't sufficient power spare to provide them, and as another example in the UK it depends far more on rolling stock age (or refurbishment date) than whether it's a long-distance train or not.
I've wondered about this while tossing around the idea with an old boss. LA is notorious for being a difficult place to build or expand a freeway, and the congestion problems are getting worse.

It seems you have to get them pretty high before you can travel very efficiently, so they don't work for going across cities. That's not even worrying about the local airports' airspace and the numerous tiny municipal airports. I don't know that these are intractable problems, though.
The I-5 stretch is almost a straight line, spans a single state, is already very wide with a comfortable median, and sparsely populated along the way. Those things all have their advantages.
Don't call it "server manifest". It'll confuse people. You mean "inventory". You can dynamically populate "facts" and "inventory". See:

https://github.com/ansible-provisioning/ansible-provisioning

http://jpmens.net/2013/06/18/adapting-inventory-for-ansible/

Especially for ec2 there is many modules that allows you to do that too. You can easily specify an inventory file which you populates dynamically.

There is also a lot being done about this in v1.3.

HTH
Same basic concept as the others. Ansible has Playbooks to Chef's Recipes. Ansible has Vars to Chef's data bags, and template files just like Chef or Puppet. For some reason, Ansible just ends up being much simpler to get going with. Probably because you write playbooks in a very straightforward yaml syntax, and the topology is not client-server - you just run Ansible right from your local terminal, like running knife I guess, with chef-solo. Just look at the documentation on their site, there's basically 3 or 4 pages you need to read before you're writing playbooks. I've worked with all three, Ansible is far and away the only sane one if you ask me.

One tab can freeze (because of the js, for example) without killing the rest of the browser.
Exactly how do they differ? My impression is that the net result (depreciation of cash assets) is the same.
The two things that makes me prefer ansible over chef/puppet/cfengine are:

1) being push based

2) working via shell over ssh.

There is a definite vantage, with a small install base, in not having to setup a server on either side and being able to control the process from the "admin" machine.
What would make ansible perfect for me would be ditching yaml and use python directly. It would be easier to extend and control programmatically, without the awkward variables and looping constructs it uses in yaml.

That's interesting. What were they saying? Any sources?

Personally, I don't care about soylent, because like I said, it feels a bit premature to try and make heads/tails out of any meal-replacement plans anyway. But yeah, given that they were marketing themselves as 'consulting with nutritionists' (I believe, could be wrong though), that's interesting.

Either way, it's important to note that Nutritionist != Dietician != Scientist/Researcher.
Obama swore to protect the Constitution

and now distracts everybody that his goal is to "protect the security." In 2006 he called G.W. Bush on the same ground!

Even the "secret" FISA court, the only court in charge of NSA, decided (in the decision that is still classified as "secret") that what NSA does is unconstitutional.

The President still does the distraction of the public with "protect the security." Don't let this remain unnoticed.

aha! there is the term I have been looking for all along, "shadow profile"!. I just knew there was something going on in the back ends that seems to keep me connected even when I was not even connected. Sadly, they (FB) are not the only ones who keep this information around, building up your profile with crumbs left by others. The problem is that we are interconnected and while we can be friends with people who respect our privacy and do not opt in to allow "contacts access" in all apps they install, they themselves may not have friends who think the same. Therefore, you are talking about your friends' friends allowing access to their contacts, which in turn probably exposes you as well and this probability just keeps on increasing with the number of friends/acquaintances you have. It almost seems useless to try to avoid it, but we can hopefully at least push for way to have our shadow profiles cleared completely when requested - by law.
That is a really gross exaggeration.

jQuery only lost 10% of its size on full builds when it eliminated IE6-8.

There is still plenty of stuff left to handle. Naive code that only handles common success case is of course going to be small. Even if the modern browsers didn't have bugs and behaved exactly the same, you would still have most of the stuff there.

jQuery features amazing event model with endless corner cases and optimizations* handled, powerful ajax library (Think of stuff like prefilters and transports) and so on.

* For example your typical delegation implementation traverses the propagation path over and over again for each handler, while probably not even checking for simple selectors.

It seems fairly limited right now, and doesn't do much to alleviate the pain of supporting many different push notification services.

You still have to code the client side pieces for each platform separately instead of providing a uniform SDK, you then communicate the notification URIs "somehow" to your own backend and store them on your own. The only difference seems to be that you would then talk to Amazon's API instead of directly to for example Google Cloud Messaging from your backend. I'm not sure it's worth introducing an abstraction layer just for this slim piece. Hopefully they'll broaden scope later on.
