Comment Re:Wildly premature question (Score 1) 81

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.

I live in a port city and see lots of ships, but I'm not sure this baby could even enter the harbour here.

It's far bigger than what the Panama Canal can handle (maximum 290 meters long), as well as the Saint Lawrence Seaway (225 meters). The Panama Canal was designed for the largest ships of the day, RMS Olympic and RMS Titanic.

Second all of that from Germany.

Energy companies - privatized. Prices have gone up, service is still good mostly because of government regulations, the market is now largely dominated by less than 5 big energy companies. Only recently thanks to renewable energy have smaller, local players re-emerged.

Public transport - long distance privatized. Service down, delays up, lots of smaller stations have been closed and lines discontinued, government subsidizes the whole thing still.

Telecommunications - privatized. Looked like a success for many years, but now that the old monopolist has stopped being a dominant player (it wasn't broken down like AT&T), service is going down the drain and prices are secretly climbing (base fees are low, nobody dares being the first to raise them, but they're all adding all kinds of additional charges, reducing service for the base fee so you have to buy a higher contract for the same, etc.)

Pensions - being dismantled as we look. We had a great state pension system. It survived both world wars and managed to pay out pensions even when the rest of Germany was flat broke. Heck, even in the few years after WW2 when Germany didn't exist at all and it was just an occupied zone. Now the state pension system is being systematically dismantled by politics while private pension funds and insurances work hard to convince you that you absolutely need them or you'll be poor when you are old.

The examples go on and on and on. In the end, it is quite clear that what my old philosophy teacher in school said was right: capitalism, communism, fascism, extremism, islamism, doesn't matter, be aware of everything that ends with -ism.

The free market is a cute idea and it works great for trade. But don't make it a religion. Many human endeavours are not trade and not suitable to be treated like that. I hope we all agree that things like art and love fall into that category, so we should be open to at least discussing if health, transportation and communications might fall into it as well.

The same is true for communism. The idea that every is equal is great for politics, and a lot of what's wrong in the west today is caused by our hidden abolishing of the "one vote per citizen" rule by allowing campaign financing to dominate the results instead of votes. But again there are lots of areas where treating everyone the same is not the right approach. Education, science, sports and business are all places where it's good if people start out with equal chances, but as their talents and abilities emerge, they need to be treated differently. And planned economy has been pretty much proved to be a disaster, too.

In every other -ism you will always find at least one small grain of truth. Maybe even ISIS has a right idea in its idiology somewhere. The problem is always if you think you can explain the whole world by one truth, one interpretation, one approach.
But religion doesn't built space ships, and science doesn't write operas, and capitalism doesn't create families.

Take advantage of the system

(1) Find the best college or community college that'll have you as an English teacher
(2) Teach English for small $
(3) Take advantage of the perquisite that you get to take some amount of free classes because you are faculty
(4) Finish an associates in a STEM field. An associates is transferrable, even if credits are not (I suggest microbiology)
(5) Either transfer as a student, or, if it's a good college, finish your bachelors degree there
(6) ...While still teaching, if you can; 1-2 years experience teaching at a college level puts you higher on the hire list

NB: "Good college" is relative; you will generally get out of any program what you put into it.

Comment People without degrees tend to lack the vocabulary (Score 2) 280

People without CS degrees tend to lack the vocabulary necessary to communicate efficiently with their peers about CS topics in situations where they are required to work on a team. Big "O" notation, names of algorithms, breadth of algorithmic knowledge, etc..

If you are not going to be working on a team (and it's the rare company who does not believe they will become larger in the future), then a portfolio of previous work is generally acceptable.

Because companies believe they will grow, you are most suited to being a consultant, or, alternately, working for a consulting firm.

I've frequently considered creating a "vocabulary test", along the lines of those multiple choice test games passed around on Facebook; the problem with doing that, however, is people would "learn to the test"; and while it would be a form of education for them, as a result they would successfully get their foot inside the door of place where they would ultimately not be successful. This would not be a service to either them, or the places which hire them. To be effective, it would have to end up growing to the point that it might as well be a certification exam. And still, people would learn to the test, instead of having any depth of knowledge necessary to communicate with those who do.

Linking Drought and Los Angeles: Easy To Do

Northern California sends most of their water south to Los Angeles so that they can grow water intensive crops like walnuts, rice, avocados, etc., when other crops would take hugely less water (but not be as profitable). Sadly, agribusiness pays a deeply discounted price than the rest of us, so we're effectively subsidizing their shrinking water bills with our ballooning ones.

If Los Angeles would just *catch* their run-off, instead of dumping it into the ocean using their huge drainage system you tend to see in Terminator movie car chases, and walked down at the end of Buckaroo Banzai, they wouldn't need to take all the water from Northern California, or most of the water from the Colorado river.

How much of the recent torrential rains in California that happened to land in the Los Angeles area do you think ended up in storage systems, vs. the ocean? I'll give you a hint: not a lot.

I agree that there's the difference of book or not, but frankly speaking, most christians known only the summary version of their holy book and never actually read it, so the difference is, again mostly semantical.

That christians today don't want to kill unbelievers and heretics anymore has little to do with christianity itself and a lot with the enlightenment and the secularisation of society and politics.

Quad core - this thing may be in the next MacBook Air

I've heard that so often, it's time to burn the strawman.

In "such situations" (red flag right there - vague specification), only the pre-planned, very bad guys with proper resources and connections are armed like the military.

Most bad guys are lacking either the resources or the connections or the patience to jump through all the hoops that you need to jump through to acquire, say, an assault rifle illegally. In my country, which has strict gun controls, very few crimes involve weapons of any kind, and in those that do the weapon is almost always either a knife or a pistol. That means regular police can engage the criminal.

That's probably because Christianity does not require believers to spread the faith

Semantically correct, but the step is so thin it's not a surprise so many christians throughout history thought otherwise.

If you know (not suspect or think, but know by divine message from the creator himself) that everyone who doesn't join your faith is doomed to eternal suffering in this world and the next, and their children and their children as well, you either feel a strong impulse to teach them the "truth", or you're not really serious about it.
