That's a hell of a lot more difficult than most US employers are used to. A lot of companies here offer what is called "at will" employment, which basically rounds down to "we can fire you whenever, you can leave whenever."
See how that wouldn't necessarily align well with the Brazilian way of doing things?
Not always, look up "implied covenant of good faith and fair dealing" which can be a broad exemption to "at will" employment in several States including Utah.
You can, certainly create an AMI preconfigured with all of your libraries, packages and services ready to go, but the issues arise over time with package updates, system updates, one-off configuration changes .. the list goes on.
The actual configuration of your system will drift further and further away from that templated AMI, leaving you to constantly have to build a new template every time you deploy a new machine, or manually make all of those differential changes to your new system.
Config management can be tailored to rapidly update the configurations of certain classes of systems at a greater interval than the constant cycle of blowing away machines, updating templates, redeploying, etc , etc.
Unfortunately, in the US, with so many public schools striving to meet benchmark scores on standardized tests that require little critical thinking. . .the answer is yes, that's increasingly left out of the previous 12 years' curriculum.
This is largely FUD in well-to-do districts. Having gone through the public school system after NCLB was passed in a district consisting primarily of upper middle class students, I rarely heard NCLB or the related standardized tests mentioned. And when I did, it was in the form of a derogatory remark from the teachers.
Of course, things may be very different for people from other socioeconomic backgrounds.
Is that really a symptom of Facebook deliberately trying to wall its users in, or just that the the majority of its userbase really would get phished/infected/anally-probed without the warnings?
I hope they carry over the WunderMap. Of all the radars I've browsed, theirs is definitely the quickest, and has all sorts of layers to customize it with. (As well as a multitude of station readings.)
It looks like they'll be keeping the Wunderground site as-is, but I've learned from past experiences that those kinds of statements don't hold up too well down the road ..
I don't see it as giving up, but rather tighter integration. It's easier to just check a box by your status saying "yeah, you can let people know I'm here," instead of the old option where it was a completely separate input.
