Mostly I am on Stackoverflow.com where new/experienced programmers share their knowledge. When a new user asks his first question, the question can be downvoted because the user's question is a bad question. They do not read the  document which helps users to ask a good question.  Now what is the point of the possibility of downvoting a new user's question if it is already -1? Example: . A question which has now -8.  Of course, there are a few things about the user's question that make it a bad question. But why can users downvote a question if it is already -1? What is the point of showing -8? The point that the question is bad is already indicated by the -1 (note: only people with 125 reputation can publicly downvote a question).   I feel -8 does not have any added value to the user itself. I think when he sees the -8 he just leaves the website or anything other than positive. It is now like: "Hey man! Bad question! Here, have a downvote!" times eight  Especially for new users, I think it is important that a review should be made when the question received a downvote. The question should be on hold and "normal" people should not be able to downvote/see the question. When the review is made, the mod can decide that the user should rewrite his question to make sure people see it again. I already thought this was possible, but I think it is a great idea to not bash away the new user, by simply spam downvoting his question.   What do you think about this? Is it okay there is no limit on downvoting a new user's question?
There has been a trend now two persons downvote it then it goes on like that. So let there be down voting but do not display the downvotes till the user votes on it. Else the user reads it with an impression that the question is not good.  Am I missing something?
How do I fix my locale issue? Trying to identify pre-1970s short story involving multiple humans absorbed into an alien blob I think this story dates from the 1950s, plus or minus a decade - I read it about 30-35 years ago in a (then) fairly old story collection. It involves explorers on a planet falling into a gelatinous object that dissolves most of their bodies except for their brains and nervous systems. About four of them fall in to the same creature, and they discover that by thinking about it they can grow limbs and other body parts. At first they try to fight each other, by growing arms so they can hit each other's brains - and one of them realises that growing a skull would be a good idea - but later they agree to grow legs and move the creature around co-operatively. I would love to identify this story. Why can't I press the Install button when installing applications from unknown sources? I'm trying to sideload an application, as seen in the picture below.    I have allowed the installation of applications from unknown applied actions in settings, but I can't seem to press the install button. The cancel button works correctly and installing applications via adb install works correctly. What's the problem?  EDIT: For those who have this problem, using ChainFire's  will correct it because the app uses hardware compositing, and Android doesn't notice a "layer" on top of the current screen. First, I'll state some background that lead me to the question.  I was thinking about quantization of space-time on and off for a long time but I never really looked into it any deeper (mainly because I am not yet quite fluent in string theory). But the recent discussion about  got me thinking about the topic again. Combined with the fact that it has been more or less decided that , I decided I should give it a go.    So, first some of my (certainly very naive) thoughts.  It's no problem to quantize gravitational waves on a curved background. They don't differ much from any other particles we know. But what if we want the background itself to change in response to movement of the matter and quantize these processes? Then I would imagine that space-time itself is built from tiny particles (call them space-timeons) that interact by means of exchanging gravitons. I drawed this conclusion from an analogy with how solid matter is built from atoms in a lattice and interact by means of exchanging phonons.  Now, I am aware that the above picture is completely naive but I think it must in some sense also be correct. That is, if there exists any reasonable notion of quantum gravity, it has to look something like that (at least on the level of QFT).  So, having come this far I decided I should not stop. So let's move one step further and assume string theory is correct description of the nature. Then all the particles above are actually strings. So I decided that space-time must probably arise as condensation of huge number of strings. Now does this make any sense at all? To make it more precise (and also to ask something in case it doesn't make a sense), I have two questions:        In what way does the classical space-time arise as a limit in the string theory? Try to give a clear, conceptual description of this process. I don't mind some equations, but I want mainly ideas.   Is there a good introduction into this subject? If so, what is it? If not, where else can I learn about this stuff?      Regarding 2., I would prefer something not too advanced. But to give you an idea of what kind of literature might be appropriate for my level: I already now something about classical strings, how to quantize them (in different quantization schemes) and some bits about the role of CFT on the worldsheets. Also I have a qualitative overview of different types of string theories and also a little quantitative knowledge about moduli spaces of Calabi-Yau manifolds and their properties.

I have a 8 GB pendrive. I used to write raw data into the pendrive (without creating filesystem) using the dd command.    Today, when I inserted the pen drive, the I am unable to write anything on to it.  When I open gparted it is showing the total space on the pen drive as 500 MB.

(udisks-error-quark, 0) How do I withdraw a paper from a journal after it was accepted but before it was fully published? On the advice of a senior colleague, I decided that I do not want to publish the paper anymore and with that journal. I wrote the editor several times; he has received the emails, but refuses to reply. I know he gets the emails because if its on other matters he has replied but not on the paper. I am ready to forfeit the processing fee I gave them but they refuse to reply and have already published the abstract of the paper to their site but not the full paper. Is legal action an option and do I have the right to sue? What are the guidelines in matters like these? Target filesystem doesn't have requested /sbin/init General Relativity Equivalence Is Einsteins Equivalence theorem in General Relativity correct? It seems to me that it neglects the fact that gravitational acceleration depends upon separation distance squared, thus neglecting the effect of tidal forces.   For example, as I sit on earth, I experience the affect of earth's gravity; Although the acceleration on my head is slightly less than the acceleration acting on my feet. If I make the claim that my frame is equivalent to me being in a space ship traveling at g, doesn't that mean my whole body is accelerating at g uniformly? This is contrary to the previous statement though. is a typical example for , though it is said that long time no see has been accepted by the mainstream English speakers.  Recently, there is a  movement in the , and a few new Chinglish words have been invented to demonstrate the characteristics of the Mainland.  The most outstanding examples (in my opinion) are:   shitizen - a citizen without citizen rights freedamn - the freedom for shitizens (no freedom) democrazy - the democracy for shitizens (no democracy) smilence - the speeches under the freedamn of speech () z-turn - to make effort in vain ( (Pinyin))   Here are my questions. Has there ever been any neologism movement in the history of English? What are the criteria to adopt new words into English? Can thebibliography be sorted by citation order?

Where did the age go on the network profile? Ever since the profile redo, the age was shown in the network profile, but not in the per-site profiles.
