copying

Issue is what the title says. Earlier I used to copy text from text files open in vim simply by selecting text and doing Ctrl + C . But now it puts me into visual mode, thus not allowing to copy the text. Its really annoying. Anybody knows any fix for this. Thanks. Dan Lowe You probably have the mouse mode active. You can turn it off with: :set mouse= And turn it back on with :set mouse=a If you are using iTerm, you can leave mouse mode on all the time if you want, and hold Option when you want to select without using visual mode. I am not aware of a way to do that in OS X Terminal. Update

Frequently, my workflow involves data cleaning/munging in an IPython shell. This has become particularly wonderful since IPython version 5.0 with all the great upgrades to the terminal interface . So, let's say I make an attempt at sprucing up some piece of unstructured data: In [11]: for i, (num, header, txt) in enumerate(data): ...: header = [e.strip() for e in header.strip().split('\n')] ...: header[4] = header[4].strip(',').split(',') ...: data[i] = (num, header, txt) ...: Fantastic, it works! But now, I would really like to add this to a script in my editor. If I copy and paste from my

I'm trying to copy my .profile, .rvm and .ssh folders/files to a new computer and I know how to use the cp and ssh commands but I'm not sure how to use them in order to transfer files from one computer to another. Any help would be great, thanks! Ether You can do this with the scp command, which uses the ssh protocol to copy files across machines. It extends the syntax of cp to allow references to other systems: scp username1@hostname1:/path/to/file username2@hostname2:/path/to/other/file Copy something from this machine to some other machine: scp /path/to/local/file username@hostname:/path/to

I have an Image. I need to make a exactly copy of it and save it to BufferedImage, but there is no Image.clone(). The thing should be inside a calculating loop and so it should be really fast, no pixel-by-pixel copying. What's the best in perfomance method to do this? Levster You can draw to a buffered image, so make a blank bufferedImage , create a graphics context from it, and draw your original image to it. BufferedImage copyOfImage = new BufferedImage(widthOfImage, heightOfImage, BufferedImage.TYPE_INT_RGB); Graphics g = copyOfImage.createGraphics(); g.drawImage(originalImage, 0, 0, null);

Does anyone know of a way to copy files with Paperclip using S3 for storage? Before I try to write my own, I just wanted to make sure there wasn't already a way to do this. Thanks After some more messing around with paperclip, I figured it out. It's ridiculously simple to copy files! # Stupid example method that just copies a user's profile pic to another user. def copy_profile_picture(user_1, user_2) user_2.picture = user_1.picture user_2.save # Copied the picture and we're done! end This also works great with amazon s3.
