If none of several cables doesn't work chances are it's not the cable or all the cables are broken. Try to ping 127.0.0.1 ... if that doesn't work it's the configuration of your network card (driver/low level protocol) or the network interface itself is broken. In the former case i'd check the config of the interface, In the latter case, i'd buy new pci network card as suggested. They are cheap. But i'm on Linux, checking a config is fingersnip ... Edit .. oh, or your router has a problem with the pc ... dns ... ?

Possible evidence of cellphones affecting human brain found
Green Baron replied to Darnok's topic in Science & Spaceflight
Yeah, i was aware. My reply tried to adress the misunderstanding :-) The article states little evidence but a guess on magnetoreception. It's probably too early for a thoroughly researched paper, and some passages seem to be a little on the .... mystery side ? Edit: well, guess is a little sloppy, it's one possible explanation about what was found in some animals about perception of magnetic fields. -
Possible evidence of cellphones affecting human brain found
Green Baron replied to Darnok's topic in Science & Spaceflight
Many organisms had and have the ability to detect a magnetic field, they use it to find prey or for orientation. Until now i assumed that humans lack such an organ and sens. Cellphones emit radio waves in the 2-3Ghz range, which are microwaves (electromagnetic). The early cellphones where a danger since they didn't have a ability to reduce transmit power when close to an antenna. Many people complained about hot ears and headache after longer calls. I personally would say: it's like smoking and alcohol, even if it would kill noone would stop :-) Of course microwaves still affect tissue up to being carcinogenic, but the transmit powers are low and it is never far to the next antenna so powers are low. Today it is thought that the effects of cellphones on tissue can be neglected. But electromagnetic impact on tissue is probably a different thing that what this article is about. btw. the refrenced article on a human magnetic sense says nothing about cellphones ... oh ! Edit: ... except that one of the scientists used an ipone to detect magnetic dust on the "guinea pig". I ask myself, is that serious ? -
I love these flashes of the mind as well. That's better than any drug can give us :-) Foehn: You need a mountain ridge and steady winds that bring somewhat moist air. The air is forced to climb when it hits the ridge (and there is no or little way around) and cools accordingly at the dry adiabatic gradient of around 1K/100m. When it comes to the dew point it condensates to clouds. When it has to climb further than the dew point it will start to rain out, cooling only wet adiabatic at 0.65K/100m. When it flows over the ridge it will start to sink, but because the air now has lost a lot of water it will gain temperature at the dry adiabatic gradient of 1K/100m and clouds will dissolve quickly. Thus the air is dry and clear. On the leeside in and after the "cloudfall" there often are high windspeeds and gusts because the air gains a lot of energy on it's way down ..until it hits a layer of warm ground air or it is strong enough to move the ground-air layer away. Islands like the Canaries or Hawaii lie in the tradewind-zones with steady NE-winds, so they have a wet, lush green side and a dry, arid SW-side. Which is the right side to mount a telescope :-)

Reality check: The most probable other body in the solar system is Mars, right ? Mars will in a few decades (probably) be in our reach for an actual expedition. Mars is assumed to have had flowing water and it is in the "habitable" zone (i hate that word because it's grossly misleading). The assumption is based on eyeballing geological formations and comparing them to those on earth, based on a basic working principle of geology. Now in the first semester of sedimental geology the professor will tell you to never judge an outcrop just from eyeballing. As long as noone has actually been there, taken a probe, made a thin section and had it under a microscope, made further analysis, any assumptions about flowing water in the past of Mars remain a hypothesis. Mars has no tectonics, otherwise we would see transform cracks from plates moving over the ball. Good news: the surface was not exchanged since then and the old surfaces aren't buried under kilometers of sediments or subducted into the mantle. Let us assume there existed flowing water long enough and the conditions were right for a along enough time that microbes did form before water and (most of the) atmosphere were lost. It obviously didn't spread all over the surface. Would traces (remains of their metabolism) in the right places (where are these ?) be found ? It could take hundreds of years of robotic or human expeditions and whatever suits your fantasies until such a place was luckily found, if it exists. What i want to say is that there are too many uncertainties for a clear "yes or no" from the distance. All the other of the above bodies in our solar system are just playgrounds for the mind and movies right now and extrasolar projections are based on very little data, like distance from the star, orbital period and size. The rest is derived from that, often led by enthusiasm.

A plausible scenario and by far the most probable. And a valid solution to the fermi paradox. But this is a space game forum and people are ambitious to discuss :-)
-
... improbable that vents are the only places. Ridges and transform cracks as well as hotspots are far more "productive". I don't think that cold world's would have life present or maybe it could take billions of years to get specialized microbes, but a single event or slight change resets it.
-
Absolutely. From a palaeontological point of view i would consider it improbable. But not because of snowball, the oldest supposed snowball situations are much younger than the first microbes, but because the tectonic processes where much faster. That means that there was much more ocean floor activity (active ridges, transform cracks, active continental edges, ...) and thus many more heat sources than todays vents and middle ocean ridges. Traces of early ocean floor are gone cause ocean floor, due to it's high density, doesn't grow much older than 200my before it get's subducted. Regarding earth, tectonics is one of the necessary ingredients for life(tm) and the early rapid tectonics might have accelerated or even triggered the forming of life. At the end of the archaean 3/4 of todays continental crust was formed. With todays stressed environment an event like the e.g. the deccan trap would surely be contraproductive to life ... Edit: Ice moons, if we project earth-conditions to other bodies, must have some sort of heat producing activity, presumably through tidal forces, that's where to look. If someone would care to take a look ... :-)

I'm still waiting for reasonable weather. It's either cloudy, windy, too much dust and moisture in the air or the moon shines bright. Most of the time it's a weighted permutation of these factors ... :-/ My setup is a 115/805mm apochromatic refractor (LZOS) with 2,5" flattener (noname), a used 2mpx color-CCD Cam (Atik 420c) and all that mounted on a Losmandy G11, no goto, simply motorized. I also got a chinese branded (GSO) 200mm/f5 newton but that needs a lot of adjusting and the viewfinder is allways in a positon for vertebra-luxations. Maybe when i got the hang of it i'll use the reflector, because the setup with the apo only has a field of view of less than a moon-diameter (1/3 of a degree or so). That means Andromeda for example is too big to fit. As i can't look through the telescope when the cam is mounted i focus with a self-cut Bahtinov-mask. First attempts on the moon and a nebula (i don't know which) where ok but blurry due to atmospheric disturbances. I also had a small drift in the setup during 2-3 minutes exposures, probably due to an imbalance on the moment. A planetary/guiding cam is ordered, i plan to guide through an 80mm-refractor, piggyback on the apo, like MaxPeck with PHD2 if the camera and mount understand the software and vice versa. For this (and Morrowind while waiting for 1.2) i reactivated a Windows 7 partition and regretted that deeply. Error "messages" like "The side-by-side configuration is incorrect" remind of the bad old days when i had to use that "os". The most colorful images are made with monochrome cameras using filters, L-RGB is one technique, using filters for the colour-channels and luminance (usually IR/UV-cut or so-called "contrast-boosters") for the brightness. Other filters include narrow-band H-/O-/S-filters for different elements. Colour is applied by software later. MaxPeck allready gave a nice description how the image frames are stacked. Some make more: dark images from the chip at the same conditions (temperature) for the subtraction of noise and hot-pixels, flat images of an even grey tone (like against a blanket) to account for an uneven field, vignetting or cold pixels, bias frames to account for the basic readout noise of a chip (what you get without anything exposed), ... To scare away anybody who might think of trying astrophotography i searched and found this in a forum somewhere: Acquire data frames, Acquire dark frames, Acquire bias frames if using scalable darks, Acquire flat field frames, Acquire dark frames for flat field frames of same exposure time as flat field frames, Create master dark frames, For master dark frames of the same exposure time as the data frames, make a median combined master dark frame. If using scalable darks, First create a master bias frame by median combining the individual bias frames, Subtract the master bias from each dark frame, Median combine all dark frames to create a scalable dark frame. Create master flat field frames, Median combine the matching dark frames to create a master flat field dark frame, Subtract the master flat field dark frame from each of the individual flat field frames, Median combine all calibrated flat field frames to create a master flat field frame. Apply the master bias frames created in step 6bi above to each data frame if using scalable dark frames, Apply master dark frames to each data frame, Apply master flat field to each data frame, Align all data frames, Stack data frames by adding, averaging, median combining, etc. Perform final image processing. May i direct your attention to point 13: that probably is either a click with RMB and delete, or 2 hours of dragging saturation curves and applying sharpening filters. F5/F9 in our language. Ok. Message: equipment isn't everything. And, of course, we still can just point our contraption at the sky and press the trigger. Or mouse button. Or whatever. It works, maybe not as perfect, but it works. The rest of the week shall be cloudy and the moon is shining bright ... 1 day until 1.2 :-)

what was the lowest Dv margin you haved for a flight?
Green Baron replied to omelaw's topic in KSP1 Discussion
I'm playing again since 1.2pre :-) 0.6 m/s, returning from Minmus during in a career game with a standard rocket. "Normally" it's around 30-200m/s from within Kerbin SOI just because i know my designs. (A little) more from other planets depending on transfer window and ISRU. -
Any new recipes of disaster for KSP 1.2?

This mod makes it fun again to drive around on other bodies, after months of absence. Thank you ! I noticed that the ladders are somehow not working correctly, especially those of the crew/science module. A Kerbal is likely to fall through and between the wheels because it doesn't get a grip on the end of the ladder. Coming home, it cannot enter the cabin because it falls off the end of the ladder before it gets a grip on "B" or "F". Just a hint, of course it can jetpack ...

How To REALLY Get Angry At Space Science Deniers

But it would not help :-) You cannot convince a believer, be he/she a flat-earther or an "8 devs left"-conspiracist ... Ooops -
How To REALLY Get Angry At Space Science Deniers
Green Baron replied to NeoMorph's topic in The Lounge
@Kulebronis Russian. See last page. Russians - due to the communistic past - had a very secular educational system. Religion was suppressed. He mentioned Syberia, where the last shamans lived until the beginning of the 20th century. Interesting ground for prehistorians .... shamanism in subrecent circumpolar people ... similar symbols in wall paintings and cave art ... Forget it, off topic ... :-) -
What Facts Do We Know About The Devs Leaving?

What Facts Do We Know About The Devs Leaving?
Green Baron replied to Mycroft's topic in KSP1 Discussion
You have one, in the Announcements. If you don't believe it pls. keep it to yourself because it leads to no good and it's starting to annoy people, like the devs (see above) and meanwhile people like me as well. Your point of view is wrong. In the contrary, 1.2pre is the far more stable than 1.1.x. You're wrong. It has improved. That is simply none of your (or my) affairs. It's their business. So ? Sadly no. But i bet there are far more happy than unhappy ones. The unhappy ones are just louder. That's none of your affairs. ??? lacking content ... you bought it, you used it, you can do with it whatever you want. And most probably your wishes conflict with those of others. You have an answer, you don't believe it. Don't blame someone else. What makes you think you're entitled to get one ? What is it, with every new sub-release teammembers come and go and every time a mob starts to lament about virtually nothing. "Help, they are taking my toy !". It.is.ridiculous. Over and out. -
What Facts Do We Know About The Devs Leaving?
Green Baron replied to Mycroft's topic in KSP1 Discussion
You guys have A LOT of sparetime to spend on nothing. Are you really so concerned that your favourite toy could be taken from you ? Somehow pathetic. Even if this was the case that's no excuse for weak accusations and false rumours. Lean back, breathe through the nose and wait for the new release. Or go play something else. Or, maybe, go to work and do something usefull but stop spreading this nonsense. On topic: 1.2pre makes a very stable impression on me (just a few hours) compared to what was delivered before. A lot of people spent a lot of work on sorting out old issues, apparently they moved on now. Only glitches remained. I'm looking forward to 1.2 and appreciate the work and efforts of all involved. -
A very nasty phantom forces bug
Green Baron replied to Sharpy's topic in KSP1 Technical Support (PC, unmodded installs)
It is present in 1.2pre stock, unless i strut the tanks on top with 4 struts. Could be a floating point fluctuation, added up through the tank stack, thus leading to that kind of "resonance catastrophy". In terms of my understanding of game physics the rocket-tree is "upside down". Also the tanks have high mass, any dampening force is seemingly not enough. Empty tanks are stable. For my playstyle i can ignore this behaviour because i rarely put tanks on top of multiadapters. It does not happen whith science containers on top of adapters or when the tanks are empty. I often put stacks of probes on multi-adapters and the problem never occured. 4 Struts solve/surpress the problem. Like kiwi i would say: reminds me of real life ... :-) Edit: like the bug report suggests, it's not critical ... -
Pure semantics. rdem sees the root of civilization as the emergence of settledness, division of work, social stratification. If you define civilisation on that base he is right (e.g.: excavation of ancient Jericho on the banks of the river Jordan), todays Jordan is part of that area which covers the Levant, Jordan, Syria, eastern Turkey, parts of Iraq and northern Iran ("fertile crescent"). Africa is the cradle of humankind, of the genus und most of the (sub-)species of humans, be they civilized or not :-) Furthermore Mesopotamia saw the early "civilizations" that built cities, had an administration, had some sort of "king" or chief and spent a lot of time in beating the neighbours up. Sloppy said. Like Sumerians, Akkadians, Babylonians, ....

I dislike this. Likes could be understood as an encouragement to improve quality, dislikes might lead to the contrary. People start to dislike posts that are not along their view of things. That'll be against the multitude ;-) Also, if someone starts to dislike, people of the same opinion will follow, witch could start to steer things. That's not my understanding of a forum with contents as widespread as in this one. If i dislike something and feel the urge to let the world know i state my case, keeping it on topic (like f.e. that air-to-ground missile a few months ago). I like likes, i dislike dislikes. Peace :-)
