If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.

How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.

Weight vs. reusable life will become a design decision in rocket design.

The lastest cardboard app (the 1.3) is broken for me(display drivers?), but the cardboard is for sale at 5 dollar in China (paypal recommended)

That is including cardboard,lenses,magnets, velcro and shipping.

I might not be at your doorstep before chrismas, but such a small amount is nice for 10 minutes of fun.

Like others I found the headline confusing. I read it as "Researchers are predicting the use of Wikipedia as a vector for the spread of disease". This may mean that:

  • Disinformation and ignorance are diseases.
  • Memes and computer viruses are diseases.
  • Wilipedia contains information that leads to depression.
  • Instructions on Wikipedia lead to substance abuse.
  • This is getting entertaining, fill in your own reason here.

Exactly

Big data is a different thing from datawarehousing.

In a big data scenario you have lots of data, that you process with a highly scalable solution.

In a databasehouse you collect data from different sources and transform them in several steps to a datamodel you can create reports from it in a simple way. .

And there is the other option you just have to process lots of records from a simular source (measuring data), where you carefully monitor and tune the processing of that data.

The question does not even make a difference between this. Most of the above options are not a single person job if you want it done in a reasonable timeframe(that is before business needs catch up).

The hardware depends on the size of the data. hardware sellers are happy to sell their high-end servers with a scaleable SAN, for a price you can buy a mid class car, or even a price that is not listed.But depending on your needs a simple dell server with a good backup facility under 1000$ might suffice.

no way to tell

PS, "services" might be a way to convince you that that the solution needs to run in the cloud (to complete the buzzworld cicle) or a way to sell consultancy hours.

One of the definitions I found was:

One who makes great sacrifices or suffers much in order to further a belief, cause, or principle.

I am sure that fits. While SpaceShip II is mainly intended for a non-exploration purpose, the program has resulted in some significant advances in rocketry and White Knight II has significant non-tourism use. These pilots have been involved in other space efforts, I remember the one who was injured from the Rotary Rocket test flights. There are lots of safer ways for these folks to make as much money as a test pilot is paid. They do what they do to advance our progress in aeronautics and space.

Comment: Re:I never ever commented on the SCO issue in any (Score 1) 187

We knew what was going on when you ran your anti-IBM campaign, sometimes even positioning yourself as arguing on behalf of our community. It was a way to lend credence to IBM and MS arguments during the SCO issue. To state otherwise is deceptive, perhaps even self-deceptive.

Florian, you would not be devoting all of this text to explaining yourself if you didn't feel the need to paint your actions in a positive light. That comes from guilt, whether you admit it to yourself or not.

Go write your app, and if you actually get to make any money with it you can give thanks, because it will happen despite what you worked for previously. Keep a low profile otherwise because your credibility is well and truly blown and you can only make things worse. And maybe someday you can really move past this part of your life. But I am not holding out much hope.

Comment: Re:Bruce, I know why u r disappointed. Let me expl (Score 1) 187

So, I see this as rationalization.

The fact is, you took a leadership position, and later turned your coat for reasons that perhaps made sense to you. But they don't really make sense to anyone else. So, yes, everyone who supported you then is going to feel burned.

You also made yourself a paid voice that was often hostile to Free Software, all the way back to the SCO issue. Anyone could have told you that was bound to be a losing side and you would be forever tarred with their brush.

So nobody is going to believe you had any reason but cash, whatever rationalization you cook up after the fact. So, the bottom line is that you joined a list of people who we're never going to be able to trust or put the slightest amount of credibility in.

And ultimately it was for nothing. I've consistently tried to take the high road and it's led to a pretty good income, I would hazard a guess better than yours, not just being able to feel good about myself.

I am beginning to be wary of systemd, but no. I am talking about anal-retentive policy wonks who believe they only make the distribution for themselves and have (perhaps without intending to) systematically marginalized Debiian and made the project a whore to Ubuntu.

Some people carve careers, others chisel them.
