I have a scanned map which is a .tif file. I have geo-referenced it, and now I want to render it in 2.5D. Can i do this in QGIS? The ENC file is not available for the map I am using. The map already has contour lines on it, it is a colored sea map with black lines for contours. Land is denoted in yellow and green. Unfortunately due to company policy I cannot upload it.
I am looking for QGIS function to extract (or detect) edge from a raster, which was referred in here,  as answer by @MappaGnosis.  The name could have changed since then, or it may have been integrated into other tool... I cannot find it in my QGIS Processing Toolbox (2.14.10 and 2.18.2).  There are similar tools such as GRASS "i.zc Zero-crossing" and SAGA "Gaussian filter", but I am hoping to find this QGIS geoalgorithm.
How can I make a directory on the desktop?  I tried cd /desktop command but it gives an error  no such file or directory.  What's the correct command? Render looks darker than Look Dev mode I am trying to print a simple value for $AR1_p1 but the variable $i is not evaluating. for i in 1 2 3 4 do     AR1_p1=22     AR1_p2=23     AR1_p3=24     AR1_p3=25     echo $AR1_p$i done   It's like concatenating dynamically. Any suggestions on how to fix this?. I'm trying to connect to another computer in my house via ssh. Both computers have ubuntu and openssh installed. When I run the command "ssh username@ip" on terminal I'm asked for the user's password I'm trying to connect to. I type it but I get this error "Permission denied, please try again." I'm sure the password is correct, then why can't I access? A few years ago, I applied for a UK visa. The visa was initially refused and I had no rights of appeal. However, the refusal letter had some glaring mistakes and I sent an email to the Embassy. The refusal was "overturned" by an ECM.  I am now making an application for a visa which has the question "Have you ever been refused a visa?". How should I answer it? What does % do to strings in Python? A guide to moderating chat Chat is an offshoot of the main site, and using it is  during their time here.  Chat is our place for:        Real-time collaboration   Meeting fellow members of the community   Less structured, casual (but still roughly on-topic) conversation      Our chat system exists to serve the main site; users of each site can gather and commune with each other.  When in chat, we expect all users to abide by our  policy, which means that we expect community members to treat each other with respect.    While it is a place where the community can go to interact on a more casual level, chat still needs to be moderated by the community and there are tools in place to help with the moderation. This raises a few questions, that are addressed here: Prove $\gcd(a,b) \gcd(a,c) \gcd(b,c) \,\text{lcm} (a,b,c)^2=$ $\text{lcm}(a,b)\,\text{lcm}(a,c) \,\text{lcm}(b,c) \gcd(a,b,c)^2$ I'm trying prove $$\gcd(a,b) \gcd(a,c) \gcd(b,c) \,\text{lcm} (a,b,c)^2=\text{lcm}(a,b)\,\text{lcm}(a,c) \,\text{lcm}(b,c) \gcd(a,b,c)^2$$  It is a part of solution of another problem I try a lot to prove it but I could not be succeed.

Cannot delete directory with Directory.Delete(path, true) Object renders black Time-Stream Crossing and Forgetfulness In The Day of the Doctor, it's explained that the Doctor doesn't remember having interacted with himself, and if he interacts with a future version of himself, the younger version forgets.  But in Time Crash, 10th solves the problem of the TARDISes occupying the same space because he remembers himself doing it from when he was 5th.  If this is true, 5th wouldn't have wondered whether or not he was going to regenerate when he did.  Does the TARDIS occupying the same space with itself re-instate those memories? Or is it just possible that I'm asking a ridiculous question that will never have an answer because Doctor Who.  :D I've got a generic dictionary Dictionary&lt;string, T&gt; that I would like to essentially make a Clone() of ..any suggestions.

Fourier transform of the indicator of the unit ball How to fix gaps between flooring planks in mid-1800s house? I live in a mid-1800s house, which I plan to sell this Spring. The original (I think) wood flooring has gaps between the planks, some pretty sizable (photos follow).  Is there any good fix for this? I've seen people use wood filler/epoxy, and it didn't seem to turn out well. Perhaps doing that and painting/dying it black might work better.  I've heard the "old" solution was to pack those spaces with rope, but I don't think that would look better than the status quo.  Any suggestions?
