Yes! Many people think they shouldn't exercise their back because it already hurts and they don't want to upset it any further. In reality, a lot of back pain comes from having a weak back. Squats help tremendously with this.
I highly recommend watching Mark Rippetoe's videos on getting stronger, and learning how to squat, bench, deadlift, and press in a safe way.
I'm amazed they raised any money. Even if it worked perfectly, the thing is so big that it's going to rub the skin raw on the palm and adjoining fingers.
Tutorials that actually validate whether they currently work.
One use case would be tutorials on deploying to IAAS/PAAS providers. Deploying always seems to be the hard part after I build something; I don't like using the same language and IAAS/PAAS twice for learning purposes. It's complicated even more so as many tutorials don't reference when they were written or which code versions they used. The site would require this information, and then use it to periodically attempt to deploy that sample to AWS/Digital Ocean/etc (whichever the tutorial is covering), and prominently display whether the tutorial currently works.
I thought about this after scrolling past a couple of times - and I think this is a good idea.
I'm thinking like a CI for tutorials. For example, I create an account on Tutorial CI (or whatever), give it the environment of the tutorial's code. It spits out a badge that I can put on my tutorial that says whether the build is passing or not. Pretty much exactly like the Travis badges you see on Github. That way, someone can verify before they even start reading that the tutorial is valid.
We've been exploring this kind of scenarios at [http://codepicnic.com], where you can create your tutorial and then run some sort of test to see if it's running (perhaps returning non-zero values from some script or testing the existence of some files) but so far we think most of the attempts are a bit clumsy and would lead to false positives.
What is the cost/technical feasibility of SpaceX being able to broadcast this landing live? The barge will be miles out to sea where there are no cell towers, so how difficult would it be and how much would it cost to stream a video from the middle of the Atlantic?
I'm pretty sure they could send the live video signal up to a communications satellite in geostationary orbit. That satellite would relay the signal to a base station which would then broadcast it however they normally do.
There are lots of comsats in GEO; no doubt some of them are open to doing a deal, but I don't know the cost. Maybe an international TV news network would be willing to do it "for free" so long as they get exclusive access?
Or they could just use an airplane to relay to signal. The technology isn't really the issue. The issue is they don't want to release a video of a rocket crashing into a barge (or the ocean next to a barge). They know such a video would be replayed in mainstream media without the "this was just a test that only had a 50/50 shot of working in the first place" context. Especially after F9R-Dev, an Antares, and SS2 all RUD'd in the past couple months.
That being said, they have announced that there will be cameras on the barge. The fact that they have announced that ahead of time makes it very likely we will see at least some footage in the days or weeks after the attempt (they'll just want to do it in a PR controlled way).
They won't do it live unless they are _really_ sure it will work.
Even if it's just a test that they know has a reasonable chance of failing, that's not how it will be portrayed in the mainstream media (see: the F9R-dev RUD)
Before cellphones there was this technology called TV. Which has been broadcasting live from around the world for decades. I think they can figure it out.
Because 2/3 of our GDP is made up of consumer spending. By making your cash worth less tomorrow than it's worth today it incentivizes us to spend. If we don't spend our money the economy grinds to a halt in a hurry.
Because all the Fed can do is issue/buy back treasuries (and MBS since Bernanke), as well as act as a lender of last resort. Banks are the ones who hold the vast majority of treasuries so they're the ones who are getting the cash for them. How else do you expect it to work?
This is amazing. It's hard to believe someone is capable of being that dedicated to something they've never really done before. I could understand how an amateur golfer who is in love with the game might set this lofty goal, but it seems Dan really had no feelings toward the game either way. More or less, he's doing it just to see if he can do it. And he's willing to dedicate 5 years of his life to this!
If his experiment works out moderately well I could see a great consulting business in training and self-improvement. If it works out really well he is now a professional athlete which seems pretty cool too.
I really wonder how being an amateur golfer would change the 10,000 hours - would it be a head start or would it hold someone back?
In theory, it might be a detriment. The brain is fairly plastic (i.e., can be reshaped and rewired constantly), but reinforced behaviors get pretty firmly hardwired. This is why "old habits die hard," and "you can't teach an old dog new tricks." Quite literally, the neural pathways we use most frequently and automatically become the hardest to rewire.
Ergo, if you've learned the game up to a certain skill level -- and then coasted at that skill level for decades -- you're going to need to rewire significantly engrained neural pathways in order to relearn the game and break through your plateau.
It also helps to be able to start young. Not only do you have more time on your hands when you're younger, but you learn more quickly. Your brain is much more plastic in childhood. Interestingly, in most of the "10,000 hours" case studies I've seen, the subject started practicing as a young kid. It's entirely possible that the learning curve is steepened or elongated for people who start as adults. A child might be able to go from beginner to master in 10,000 hours, but an adult might need many times that number of hours.
