    A really nice Python IDE is PyCharm. Give it a try. It feels a little bloated sometimes but it works better than most I've tried. I've went back to IDLE when I'm on Linux and Notepad++ when I'm on Windows. Overall, I think in Python I need way less autocomplete than when I'm working with C#.

    It's common not to "repatriate" (I'm not sure if this is the right word in English) profits. Often the money is held by a subsidiary on a tax friendly country. It can't be used to pay dividends to shareholders but is often kept as a "cushion" for hard times or for paying international acquisitions and investments. Microsoft itself, at least a while back, held a large sum of money outside the US, through a Caribbean subsidiary if I recall correctly. I think there was an article here on /. about it, but I'm not sure.

    While I know little of ITT Long Beach (I'm half planet away from California right now) you have, in the US, one of most interesting opportunities ever aimed at adult learners. This opportunity is called the Harvard Extension School.

    Don't let the Harvard name put you off :)

    Harvard Extension School is a distance learning school of Harvard University. You can take both online classes and on campus classes (in Cambridge, MA). It has a very simple - and meritocratic - admission system:

    You must take (and get at least B grades in) three pre admission courses. One of them is expository writing, which all prospective students must take. Two from a list of courses which varies from "concentration area" to "concentration area". One of the concentration areas is science, which is your interest. Before the expository writing course, you must take a placement test ("test of critical reading and writing skills", more about it here.

    Rest assured the classes are going to be as interesting (and hard :)) as if you're admitted to any other undergraduate Harvard school. You will have a instructor (and fellow students) to help.

    Harvard offers some options of financial aid for the pre admission courses (read more about it here - I'm assuming you're an American citizen, there is very limited support for international students). After admission there are way more financial aid options. Also, HES can be surprisingly cheap.

    Willingness and motivation to learn are a rare characteristic in students and should be nourished. Do something about it :) I promise you it will be way more interesting than school ever was.

    If I can help you in some way, just let me know.

  7. Re:Hamza? on Evidence Points To Huge Underground River Beneath Amazon · · Score: 5, Interesting

    Brazilians call themselves 'Brasileiros' instead of 'Brasilianos'. Interesting, 'Brasiliano' would be more appropriate from a linguistic point of view (the '-ano' suffix indicates someone who belongs or as born in a given place) than 'Brasileiro' ('-eiro' suffix indicates someone who performs a given action). 'Brasileiro' is used because the first (European) inhabitants used to perform the Brazil wood trade, hence the '-eiro' instead of the '-ano' suffix.

    Well, on a second though, that's not interesting at all.

    At least for the Brazilian coup there are declassified information showing US support and possible involvement if things did not end up well.

    Declassified transcripts of communications between Lincoln Gordon and the US government show that, predicting an all-out civil war, Johnson authorized logistical materials to be in place to support the coup-side of the rebellion. These included ammunition, motor oil, gasoline, aviation gasoline and other materials to help in a potential civil war in US Navy tankers sailing from Aruba. About 110 tons of ammunition and CS gas were made ready in New Jersey for a potential airlift to Viracopos Airport in Campinas. Potential support was also made available in the form of an "aircraft carrier (USS Forrestal) and two guided missile destroyers (expected arrive in area by April 10), (and) four destroyers", which sailed to Brazil under the guise of a military exercise.

    I wasn't really thinking about radiometric dating. Just a estimate for cooling time from micro structure cooling rates. It's reasonable for meteorites since you can often find micro-structures that are characteristic to low gravity environments (I'm no longer able to name them, I took this a side interest in the earlier years of college (metallurgical engineering) and later gave it up for computing) and date them from the cooling rates. If I more or less recall correctly you can also estimate the time for the seed crystals to form from the composition and other factors.

  12. Re:Same material? on Moon Younger Than Previously Thought · · Score: 3, Interesting

    It's not about atoms. It's about how solids are created. If you take a steel allow and look at it using a metallurgical microscope you can see it's made of many really small crystals (grains). How the atoms are organized into those grains is a function of many things, including the cooling rate. So, the scientists probably looked into the rock micro structure (the grains) and calculated a cooling rate for them. I didn't read the article but many, many, many years ago as a metallurgy student I had an interest into iron meteorites.

  13. Re:Blatant propaganda on SpaceX Given Approval For ISS Mission · · Score: 1

    Assuming Brazil could build something competitive to SpaceX, I don't see why they wouldn't be considered, but I also have no inside knowledge as to what Brazil may or may not be doing in space.

    I don't think that Bigelow would be a serious option is that it adds no knowledge to the space program. It's a box, a fancy box, a gadget. The fundamental point of the space program is to make the country know how to build stuff. Buying previously made stuff from other countries makes no sense under this light. It could still be done, if the country is unable to launch something on it's own. The first Brazilian sat in GEO was bought from Boeing, being subcontracted from Hughes Eletronics. Hughes, as part of it's contract, subcontracted Promon, a local company, for part of the work. Testing was done by INPE itself. While the satellite itself was useful, the main objective was to produce local knowledge.

    The first Brazilian made sat was also launched by an American company (Orbital) but just because a Brazilian rocket was not ready for launch and wouldn't be for years. If Bigelow offer a contract with this terms - subtracting some work for a local company - it could be a viable option. But from what I've seen in the last few years technology export licenses from the US were difficult to get (at least in the satellite area).

    The Brazilian launcher is also another problem. VLS-1 is/was a solid propellent rocket. After the VLS-1 launch pad explosion (which killed a sizable chunk of the engineering team) the choice was to build a liquid propellent rocket. After this the Russians and Ukrainians were approached for technological cooperation. The cooperation program is still going but, as I said before, I don't believe it's going far. I hope I'm proved wrong on this.

    The Ukrainian approach was to locally produce the Tsyklon-4 rocket (and to launch it from CLA). The Russians provided an alternative agreement for launching an Angara derived rocket. I'm not sure any of the approaches is going to produce viable results.

    I did not live in SJK but I used to work for a INPE contractor (besides doing a significant amount of my academic training inside INPE itself). I have no links to the CTA besides knowing a few people.

  14. Re:Blatant propaganda on SpaceX Given Approval For ISS Mission · · Score: 3, Informative

    The cited article has no links to Bigelow. It's difficult to imagine it would happen in the actual political context. One of the main aims of the Brazilian space program is to develop the local industry. Buying from SpaceX or Bigelow with a technology transfer program is difficult to imagine (there are legal American restrictions too). Buying without a technology transfer program should be a no-no and will probably be seen as a useless marketing gimmick, much like the when the first Brazilian astronaut flew in a Soyuz capsule just like a space tourist.

    The article cites the "Cruzeiro do Sul" proposed rocket family. "Cruzeiro do Sul" depends of the Russian cooperation. Russia (MAI) has been providing training to engineers. How well the training is going and how much time it will take until those newly trained engineers to be able to engage in a useful project remains to be seen. I do have a lot of admiration for the IAE guys but I don't have much faith in the Russian cooperation program. And now Jobim resigned from the Defense Ministery - Jobim was a major backer of the Russian cooperation agreement - my hopes aren't high.

    A new Brazilian capsule is probably out of question since SARA - a proposed unnamed reentry capsule for microgravity experiments - didn't even fly yet. And I'm not sure it will, considering the current deep budget cuts.

    Don't take AEB press releases seriously. AEB is the problem, not the solution. The Brazilian space program is run by two entities: INPE (satellites, space physics research) and IAE/CTA (launchers). AEB is just a useless bureaucratic overhead, created because politicians and international observers didn't like the space program being run by the Air Force (maybe out of the fear of a imaginary secret ballistic missile program).

    Where do you get that information for Bigelow and the manned Brazilian space program? I used to work on the unmanned program and never heard something like that but I've been out for two or three years now. As far as I know, there's no man-rated space vehicle planned and VLS-2 was being redeveloped with Ukrainian cooperation after a VLS-1 launch pad explosion that killed a good number of engineers. There was some talk of direct cooperation with Russians but I don't know how that went. The program is probably on freeze after this year budget cuts, though.

    The kernel patches. Over a vanilla kernel, RedHat applies a lot of patches: backporting features and drivers, incorporating solutions that haven't been accepted into upstream yet, and so on. Oracle cherry picks RedHat patches and offer their own. Now RedHat offers just a single "merged patch" which makes way harder for Oracle to cherry pick wherever it wants to. It doesn't matter to CentOS (and SE, probably) because they just rebuild wherever RedHat delivers.

    Anyway, given the amount of resource Oracle has and the slow release schedule of RHEL, I doubt they will not be able to keep track of wherever changes RedHat made.

    Tourist area means the what cariocas call the "South Zone" (and parts of the "West Zone", namely Barra). This is where Rio's own middle class lives. Going far from this area doesn't mean trouble not just for tourists, it means trouble for middle (or upper) class Brazilians and tourists alike #)

    While tourism is a significant share of the Rio economy, it's also hard to say that Rio depends on it.

    Living in Rio as a teacher, unless your friend was teaching at a (big) University, actually sucks because salaries actually suck. A relative of mine who works as a teacher earns about a 1/10 of I earn as a software developer. This immense gap between the middle class and the poor has always been the root of most of Rio social problems.

    Despite left wing protesters, I think no one care about Americans or Europeans. The only place where I could sense a dislike of tourists (Italians, actually) was in Fortaleza (northeastern Brazil). Most Italian tourists there go there for sexual tourism and, often, children exploitation. There was a general feeling among many people I met that the city would be better off without the tourists.
