How much of a cost am I going to pay if I include a GTK+2.0 file-get gui if I remove the object after I have moved the filenames into a global variable. This is using MonoDevelop C# only for the GUI. Do I run the gui, save the filenames in a text file or can I move into a C++ routine with out classes.

I think they are more worried about bugs than debris. Provided the equipment is sterile, don't see a problem. Of course if you are colonizing, you are going to have many landings at the same site. Possibly a landing platform. So best to move the debris away But also if you are colonizing that debris also represents precious metal resources, best to recycle, smelting ore on mars without a nuclear reactor is very, very expensive. With a nuclear reactor still very expensive.

Quantum entanglement is considered by some to be a quantum wormhole. This may be the only form which exists for the briefest of moments and essentially occupies no space.

Any manned mission that is currently planned qualifies, until the technologies are proven for return home, its pretty much the case. Colonizing mars in the current geopolitical climate is not going to happen, the supply line needs to have a 10 fold more investment globally in the space program to sustain, and with very little benefit from the investment other than multiplier effect in home economies (still a good reason, but the strategy is best directed elsewhere). The difference between a mars versus mars satellite or roid mission is that the largest hurdle is dV for landing requires at least some fuel as well as dV for ascent. With a roid or small satellite dV problems can be overcome by a combination of thrusters and ion-drives that are much more efficient, once the payload is orbiting the gravity well you have time to figure out how to get them back, including a (manned/unmanned station) its simply a matter of keeping them alive. You can throw resources at a shallow gravity well and expect to get a result. You may throw alot of resources at a deep gravity well and still have insufficient resources to achieve the goal. Sure mars may be easier to get to (excepting its satellites) but you don't have time with regards to descent dV or ascent dV, these thrusts are needed promptly. In space you have all the time you desire and so any means of getting dV will do, if you have a modest supply line.

Yes but inside the light emmitting crown of a star, even one that produces in the low energy part of the visible spectrum is density suitable to create drag when the satellite is orbiting around the star what are we 150,000,000,000 * 2 * 3.14. / 365.25*86400 (31557600) = 29865 m/s. KE generated = 455,000,000 joules per kg of stellar gas. so 4180 joules to boil 1 liter if water so 1 kilo of stellar gas can basically burn of 100,000 liters of ocean. Consider that the earth is traveling at 29865 m/s and its radius is 6371000, making its crossectional area along the path of travel 1.275 e 14 meters squared or an area of space captured of 3.8 e 18 cubic meters covered per second. The suns current mass is 2e30, at a radius double earths orbit it would have a gas density of 0.0001 kg per cubic meter 3.8 e 14 kg per second. This times. 455,000,000 joules per kg gas = 1.79e23 joules per second. Energy flow at the boundary of forward motion (6371000 x 2 x pi) = 4.3e15 joules per meter per second. This of course is going to be a combination of heated gas, hv, vaporized metals, particularly along the boundary, a simply the flow of molten earth along its surface, where the local gas flow is highest chunks of molten metal will simply lift off and be carried into space wher its orbit would decay into the sun.

By hiring ex-military, particularly high level administrators and procurment people they get a shoe in the door for future contracts. Its a waste of salary, but you have to grease the wheels. If privately funded space company should not need to hire ex-military or ex-NASA...........HOWEVER, if they want to get the scoop on future nasa missions and bid on a launch platform or long range sat carry they might want to have some one close enough to NASA to say, 'hey these are the missions we can do and, by the way, at a lower price than your plan so you might want to bump this project up'. If you are planning a suicide manned mission to Mars ex-gov types would prolly get in the way.

Right, its the beeb.

Yes, but the popular dogma is that stars drag and chew up the planet. Planet earth inside a red giant. 1. Atmosphere is lost 2. Suns molecules are bombarding the earths surface at 40,000 miles per hour. Imagine the earth in perpetual reentry, except a magnitude more intense per unit surface area. The entire surface of the earth would be like in the hottest blast furnace that humans could possibly make. It would be like bombarding the entire surface with a rubidium laser. I'm pretty sure but not absolutely certain that being bombarded at 40000 miles per hour would cause the heaviest metals to start vaporizing and be dragged off into the star. 3. As the surface heats up even more from the collisions the surface begins to boil molten metals and degassing metal itself. The cessation of cooling at the surface and the ongoing uranium radiativity of the core would cause the entire upper layers to boil with huge eruptions that cough large amounts of surface into space. 4. The moons orbit is destabilized and after forming a highly eliptical orbit collides with earth. 5. planet would have to survive this for 5 billion years. Each orbit spiraling closer to the star.

http://www.nasa.gov/ames/kepler/nasa-k2-finds-dead-star-vaporizing-mini-planet There is something a miss here in the logic. 1. Step 1, Star 2. Step 2, Red giant, has expanded to consume all short period planets 3. Step 3. Contraction 4. Step 4. White dwarf OK, so how is it that a planet can exist in the short period planets zone if the previous state of the star already consumed the planets in that Zone.

I think he is looking prolly at modeling dynamic force during flight of modeled parts, since this thread was ported here. For simple fusiform shapes traveling at M0.8 or less its probably going to pretty strait forward, For craft complex axial cross-sectional areas the equations above M0.8 get complicated very quickly. For most craft of this type rather than calculating drag, the effort should be in sustaining climb of 0.8g to a pressure where drag is not a major concern at Mach speeds.

The tidal forces would act along with convection to keep the heavier elements from building up in the center of the stars. - - - Updated - - - Here is the where for this binary. http://messier.seds.org/xtra/ngc/n2070.html http://apod.nasa.gov/apod/ap060106.html http://apod.nasa.gov/apod/ap140612.html http://www.nasa.gov/content/goddard/hubble-probes-interior-of-tarantula-nebula http://apod.nasa.gov/apod/ap140217.html http://www.nasa.gov/mission_pages/chandra/multimedia/tarantula2012.html http://www.nasa.gov/multimedia/imagegallery/image_feature_2231.html http://www.jpl.nasa.gov/news/news.php?release=2011-350 http://apod.nasa.gov/apod/ap090331.html http://apod.nasa.gov/apod/ap120516.html

any good album of the nebula?

Half a million years is not a long time at least in terms of a very settled universe. Stars formed, collapsed and nova more quickly 13b years back. Though for the sake of life thats a good thing, if Nova were going off every few weeks imagine how long life on earth would have lasted.

Well in the spirit of the original update i thought i would summarize my progress as it goes into some of the problems. Basically after trying fix several problems with my linux ubuntu install, it finnaly messed up the mbr of the booting drive that i literally had to reprogramm grub2 or the bios everytime the computer started. The whole thing started out bad, the reason was a fully vetted installation guide for a dual boot system is not given on the ask ubuntu site. (the folks that give answers on ask make alot of assumptions about how familiar people are with the OS, which is in the spirit of the original post). The critical ingredient was hiw to setup the linux drive. Simply partitioning the drive with ef4 format is not sufficient, one small drive of about 650 mb needs to be set up with an efi. This was not explained, the second thing is that the home directory should be on a separate partition, this allows an inhanced data protection. BTW, the correct instructions were found on one of those click baity sites. To do this right i had to wipe both windows and ubuntu, :^(. The whole problem started because the iso that was recommended was done so on a mistaken assumption, also the fault of bad explanation. Amd64 ubuntu is amd64/compatible x86-64 not solely for AMD....the i386 is for roughly any 32 bit machine. These names come for historical reasons, intel had the first 32 bit OS for the genre and AMD had the first fully 64 bit. Many of the commands were failing, lots of things didn't work. I thought gee did the installer didnt recognize my machine and installed the wrong version, nope the installer the was the wrong version. Things are definitely improved, I found an iso for 15.04, having that and having Ubuntu unleashed, i got on how to create a iso with my linux box and put the version of ubuntu on the mem pen that had the bad linux, therefore wiping it to bit-bucket land. The windows install went well, the ubuntu 15.04 install (Something else) went well up until the partitioning, in which it was not showing the values required in the list, i reset the table, didn't work, cleared values and tried again, to no avail, and the computer froze. SO i rebooted and attempted to reinstall again and this time the right partition type appeared in the list and everything proceeded according to instructions. The lesson here is bad advice not only waste time, but it can make the damage diificult to reverse.....be concise but also complete. The other thing is that 15.04 has better cooperation with UEFI so that only a few changes are needed to make the two OS compatible on the same machine. With 15.04 x86-64 running stably many things just work better. This version of ubuntu has more features, like a more personalizable desktop and more choices of programs that autoload and compiie, though honestly most are junk. Monodevelop has an install link, thank god because the install instructions on the xamarin site is (in the spirit of this thread) a waste of time. Though exceptionally on the previous version of ubuntu my sound card had a problem but ubuntu gave several solutions and one of these was the fix, for 15.04 two of the solutions were left of the list, so sound blaster now makes freaky noise like a childs machine gun. So basically the trend here is rather than provide good well thought out instructions, the linux folks have option fo push button solutions. We need a course for the GNU community on how to communicate with humans. :^) BTW my ubuntu desktop is starting to look like my XP desktop : ^).

http://www.fromquarkstoquasars.com/these-maps-reveal-how-little-we-know-about-our-own-galaxy/ There are a couple of snaeky popups in this article. The article does a good job of reviewing the topic.

You are placing way too much stock in the current values, if you only knew how much of those estimates were based on movable assumptions, you wouldn't.

You don't need to invent vacuum tubes to make transistors, and its a completely different technique to make microprosessor. Your target level processorcis the. 8080 or the Z80.....,assuming someone etched the schematics and/pricess into a gold brick and burued it some place convinient. Another target is the 200 baud modem and RS232 communications relay (a technology that is still being used). CRT are optional, but ossciloscope is stll useful for other things.

http://www.theguardian.com/science/2015/oct/19/life-on-earth-began-300m-years-earlier-than-previously-thought See what I mean about uncertainty in the dating.

80, try 99% prolly more like 99.9%. Since consider everything you eat, unless you live in the amazon is technically speaking a technology, and everything that people who lived where you live now ate, pretty much pushed off the landscape. I suspect that once 50% of the population has starved cannibalism will kick in and the population will begin to flatten out. Certainly in the big cities it would be like the siege of Stalingrad. The first skins and leathers will prolly be human. But anyway this would be a necessity, dead humans lying all around only foul the water supply and spread disease. Any one recall what Atilla the Hun did to 'Poland', you don't want that. Hah, what about Windows 10! Well there are wants and then there are wants, and there are needs. The survival needs will occupy at least the full of 3 years. In great luck you will have housing within 6 months, for whoever figures out how to make stone axes or adzes. Don't forget also, for that technology to come, the ladies are going to have to start spending most of the day in domestic occupations, gardening and farming, child-rearing. You loose half your labor force right off the bat. Industrial steel working is key, the sooner you can get to that point the sooner you can make tractors for growing crops, pressure holds for building steam engines for trains and mechanical in factory's. You can't even have an oil industry without the ability to make a distillation apparatus or a cracking unit. So if its not a big rush to get steel plating its a fail. The key multiplier is to remove sustenance farmer and put him in the factory, until you can get there you are still behind the game.

Steam engines have to many mechanic parts that have sharp tolerances. Entry level electric power can be driven by water turbine, all thats required is a shaft and a plaform and a dynamo. Once you get an electric smelter then you can build the pressure hull for a steam engine. You have to be abke to heat iron/steel reliably hot enoughbso that it can be poured and rolled. If course the first parts you want to make are the steel working tools. This is all going to be done in initially wooden factories so we can expect quite a few to burn down. Unless of course you find aluminum salts and bake lime from stone to make cement, which can be used to make foundaries of concrete beam, which of course needs reinforced iron rebar. Its not simply regurgitating textbook knowledge, its a process that will take blood and sweat and a few lives while you worknthrough th low tech hazards phase.
