It's about both cost and risk analysis. If you've got a lot of infrastructure, then you've probably already got a team of decent admins. Adding another server has a very small marginal cost. If you haven't, then the cost is basically the cost of hiring a sysadmin. Even the cheapest full-time sysadmin costs a lot more than you can easily spend with GitHub. Alternatively, you get one of your devs to run it. Now you have a service that is only understood well by one person, where installing security updates (let alone testing them first) is nowhere near that top priority in that person's professional life, and where at even one hour a week spent on sysadmin tasks you're still spending a lot more than an equivalent service from GitHub would cost.
In both of the latter cases, the competition for GitHub isn't a competent and motivated in-house team. It is almost certainly better to run your own infrastructure well, but the competition for GitHub is running your own infrastructure badly and they're a very attractive proposition in that comparison.
Outsourcing things that are not your core competency is not intrinsically bad, the problem is when people outsource things that are their core competency (e.g. software companies deciding to outsource all of the development - it's not a huge step from there to the people working for the outsourcing company to decide to also handle outsourcing management and start up a competitor, with all of the expertise that should be yours), or outsourcing without doing a proper cost-benefit analysis (other than 'oh, look, it's cheaper this quarter!').
If you think outsourcing storage of documents is bad remember that, legal companies, hospitals and so on have been doing this for decades without issues - storing large quantities of paper / microfiche is not their core competency and there are companies that can, due to economies of scale, do it much cheaper. Oh, and if that still scares you, remember that most companies outsource storing all of their money as well...
no windmills glued on the plane please
What do you think those big things under the wings are? When the throttle is at idle, they're being pushed around by the airflow from forward momentum.
It's also not just a penalty. A visual indication that someone is new might cause responses to be more gentle/forgiving. (I must be new here. Maybe I'm just an optimist)
I'd also like a "welcome back" flag for comments more than 6 months since the last time (or maybe a smarter algorithm that determines a hiatus based on previous activity). A little more personal, but also a point of information which can act as useful guidance to the reader.
A plane travelling at 500 miles per hour, at an altitude of 40,000 feet, has to lose a huge amount of both kinetic and gravitational potential energy before it's stationary on the runway. If you can capture 1% of this, then you can taxi around the airport for quite an extended period.
A number of airlines are now also powering the flight systems from the ground when connected to the terminal, so that they're not burning expensive avgas to generate electricity.
Which would be equally unhelpful for readers that are not familiar with UTC
Fortunately, for now, most readers of Slashdot are from Earth. Every time zone is expressed as an offset from UTC. Given a time in UTC, it is easy to work out what it is in your own time zone. Given a time in any other time zone, you do the conversion by first looking up the UTC offset of the reported time zone, subtracting it, and then adding your own UTC offset.
It does, but the simple fact is if you're fat and trending towards obese you're eating too much for your particular configuration.
Even that's not really true. You're eating too much of some things, but for some people it's very hard to find foods that contain enough of things that they are bad at metabolising (certain amino acids or vitamins, for example), without also including far too many of certain carbohydrates or fats that they do absorb. There are outliers who, eating what for most people would be a fairly balanced diet, are both putting on weight and exhibiting symptoms of starvation. There are a lot more people who tend in this direction, but to a lesser extreme.
