Is it possible to set the terminal NOT to scroll down to the last line when the program that is currently running outputs data on the standard output ?  I have a program that is running and is constantly outputting data to stdout thus updating the terminal and the terminal automatically scrolls down to the last line and does not let me read the data that was outputted before or other commands that I have previously run.
In Ubuntu, I want to scroll up while a command is running in my terminal window and generates new output (the command that is running is rspec). I can scroll up, but each time rspec generates a new line of console output, it throws me back down to the bottom. Is there a way to scroll all the way up? I'm using terminator on Linux Mint/Ubuntu 12.04 LTS. I found a possible workaround.  says that with stty ixon  you can turn on &quot;XON/XOFF flow control for terminal output. Being able to pause output by typing ^S and resume it by typing ^Q [...]&quot; This it not totally what I wanted though, without having to pause the output (and maybe wondering when forgetting to turn it on again), I thought there might be a simple modifier key like shft-alt with mouse wheel scroll-up. Are there better solutions?

Why is the possessive apostrophe used with time expressions and adverbs? I find myself constantly looking up the syntax of  find . -name "FILENAME"  -exec rm {} \;   mainly because I don't see how exactly the -exec part works.

Add Point to Plot3D Smoothing polygons in contour map? Here is a contour map for which all the polygons of levels are available.  Let ask how to smooth the polygons keeping all vertices preserved in their exact locations?    Indeed the contour is made on top of a grid data, you may suggest then to smooth the grid data and hence the resulting contour will be smoother. Note that this is not working as my desire since the smoothing function such as Gaussian filter will remove small packs of data and will change the range of the third variable e.g., the height which are not allowed in my application.    Actually I'm looking for a piece of code (preferably in Python) which can do the smoothing of 2D polygons (any type: convex, concave, self-intersecting etc) reasonably painless (forget pages of codes) and accurate.   FYI, there is  that does this perfectly, but using third party commercial applications is not my choice for this question.        1)    Scipy.interpolate:        As you see the resulting splines (red) are not satisfactory!  2)    Here is the result using the code given in . It is not working well!      3)    To me the best solution should be something like the following figure in which a square is being smoothed gradually by changing only one value. I hope for similar concept for smoothing any form of polygons.       Satisfying the condition that spline passes the points:     4)    Here is my implementation of "whuber's idea" line by line in Python on his data. There are possibly some bugs since the results are not good.         K=2 is a disaster and so for k>=4.   5)    I removed one point in the problematic location and the resulting spline is now identical to whuber's. But it is still a question that why the method does not work for all cases?        6)    A good smoothing for whuber's data can be as follows (drawn by vector graphics software) in which an extra point has been smoothly added (compare with update   4):      7)    See the result from Python version of whuber's code for some iconic shapes:     Note that the method seems doesn't work for polylines. For the corner polyline (contour) green is what I want but got red. This needs to be addressed since contour maps are always polylines although closed polylines can be treated as polygons as in my examples. Also not that the problem emerged in update 4 has not been addressed yet.  8) [my last]    Here is the final solution (not perfect!):        Remember that you will have to do something about the area pointed by stars.  There is perhaps a bug in my code or the proposed method needs further development to consider all situations and to provide desired outputs. Is there a single word for something that is simultaneously not interesting and not boring? I am looking for a word that would describe a concept or activity, such as playing a game X, that is1 neither boring nor interesting. In other words, it should mean ‘neutral’ wrt intrestingness (~ boringness) but still comparable on the scale of intrestingness to both ‘boring’ and ‘interesting’.  An example sentence would be  As far as I'm concerned, long-distance running is [insert word]; it is not boring but it's also not interesting.  Criteria2   Has to be unambiguous3, and may consist of two words at most. Has to be a single word. Should be formal in the sense that it is included in Cambridge Dictionary, or Merriam Webster, or both. Should not contain negating prefixes, such as ‘un-’.   Does such a word exist in the English language?  For readers' convenience, please state which criteria you believe your word suggestion has met. You may do so, e.g., by adding a disclaimer at the top or bottom of your answer. Simply writing (1., 2.) is sufficient.        1 Assume a ternary system of intrestingness.   2 If not all criteria can be met, you may relax  the requirements from bottom to top, in the following order: 4. -> 3.  -> 2. -> 1. Answers with the smallest number of relaxed criteria in this order will be preferred in accepting. For example, fulfilling  (1., 2., 3.) is better than achieving (1., 3., 4.). Situations where a  higher priority ordering fulfills fewer criteria than a lower priority  vector, such as (1.) vs (3.,  4.), will be assessed on a case-by-case  basis.   3 Words such as ‘unappealing’ thus even fail  criterium 1 because in a three-valued system ‘unappealing’ ~ ‘not  appealing’ ~ ‘not interesting’ can be taken to mean either ‘boring’ or  ‘neutral wrt intrestingness’. Almost half of disk space unaccounted for on Windows 7 computer I'm trying to determine what's eating almost half of disk on my Windows 7 Lenovo laptop but haven't been able to determine what.  I read some of the answers on this site but none of the causes seems to be the cause of my problem.  What I've done so far:   Checked Windows' System Restore points but only minimum use, either way I deleted around 2GB if usage from there Used WinDirStat and it came back with a total of 71.3GB usage at the root level C Drives properties says 135GB being used out of 138 GB total, ie, 135 GB - 71.3GB = 63.7GB missing somewhere No "Unknown" files reported by WinDirStat Windows Disk Management utility doesn't report any unused partitions or unclaimed space chkdsk comes out clean Windows disk cleanup tool doesn't report anything big, just small stuff in the lower MB range Lenovo backup tool hasn't been used nor there is a folder for the backup images   Any idea on what to look at and/or do?

Any way to control light halos in the compositor based on emission level? I am wanting to animate a row of LED lights. I have separated the LED lights from the rest of my object with the pass index/ID mask functions; currently all of my LED lights are on pass index #1.  What I want is to have a minor halo effect around the lights, but only when they are active. Currently, when I add a halo effect to my pass index #1, all of the LED lights have a halo effect regardless if the LEDs are emitting light. All LEDs are diffuse and emission shaders, so I can animate by controlling the mix amount between diffuse and emission.   Is there any simple way to have the halo effect created through recognizing light emission values, or will I have to just animate each LED as its own layer of compositing? Do I need an ESTA if entering the US from Canada by train As a UK citizen, I will be flying to Vancouver (for which I will need an eTA) and then taking an AMTRAK train to Seattle.

Why did Tony Stark leave his armor to explore the castle in Sokovia? In Avengers: Age Of Ultron, Tony Stark is the first member of the Avengers to get inside Baron von Strucker's castle, where he takes down a room full of soldiers before stepping out of his suit and travelling down a secret passage.  Why does he take off his suit in the middle of an enemy base when it might have protected him against Scarlet Witch's magic, or at the very least helped him better search the passageway with Jarvis' HUD?

In the first chapter you are supposed to slay the Kayran, this enormous beast:    I'm having a hard time with it. I drank the Mongoose potion for poison resistance and I have the Kayran trap, but it just hits me too often with its tentacles. Especially when the Kayran swings a tentacle sideways, not from above, I have a very hard time evading it.  Is there any trick besides not getting hit by the tentacles?  With a lot of luck I'm getting as far as the point where it's throwing stones. Any idea what I'm supposed to do then? Changing unusual foreign currencies in London I've just returned from several unusual countries in Asia, and annoyingly despite being told I'd have no problem, I'm unable to find anyone in London to change back to pounds.  I've tried Travelex in Heathrow, a currency exchange place, and the post office.  The currencies include cash from: Mongolia, Kyrgyzstan, Kazakhstan and Uzbekistan.  Most of the responses when shown the money is to the tone of "What the hell currency is this?" which doesn't fill me with confidence.  Any suggestions welcomed for places that may change this. Otherwise I may need to go back next year ;)
