问题 So after going through multiple questions regarding the alignment using format specifiers I still can't figure out why the numerical data gets printed to stdout in a wavy fashion. def create_data(soup_object,max_entry=None): max_=max_entry entry=dict() for a in range(1,int(max_)+1): entry[a]={'Key':a, 'Title':soup_object[a].div.text.strip(), 'Link':soup_object[a].div.a['href'], 'Seeds':soup_object[a](attrs={'align':'right'})[0].text.strip(), 'Leechers':soup_object[a](attrs={'align':'right'})

问题 Rails noob here. I'm trying to work through Michael Hartl's Ruby on Rails Tutorial, but every time I run rails server, it keeps Exiting and shows me a SocketError. I was able to run the server just fine this past weekend using wifi from a startup, so I'm guessing it has something to do with my internet connection/firewall? I also ran into the same problem with the server at the library this afternoon. Any help is appreciated! Thanks in advance. => Booting WEBrick => Rails 4.2.0 application

问题 I've added some methods to an existing project. It was writing correctly to a txt file. However i can only see my recently added std::cerr texts now, i execute my project like ./faceDemo > run.txt What are the possible reasons? 回答1: If you wish to redirect the error flow, you should use something like that : ./faceDemo > std.log 2> err.log And if you wish to redirect both flows in the same file use this : ./faceDemo > run.txt 2>&1 2>&1 means redirect error flow into std flow 来源： https:/

问题 I am aware that you can pass commands to the Terminal and it returns your result in Java. The problem is for undisclosed reasons I need a Terminal window to open and to have the command in it. This code works to open an empty Terminal window (on mac): p = Runtime.getRuntime().exec("/usr/bin/open -a Terminal"); And I have seen someone say on a different overflow question that you can do this: p = Runtime.getRuntime().exec("/usr/bin/open -a Terminal [Put Command to pass through here]"); But it

问题 In a ruby file: When I do system("rspec file_spec.rb") I get a nice colored output . When I do this: result = `rspec file_spec.rb` puts result I get no color at all. Is there any way to preserve the color ? btw, I'm on OSX with Terminal.app if that matters. 回答1: From reading the code it looks like RSpec calls IO#isatty on the output stream to decide whether or not to colorize the output. The backquote method must work differently from system in this respect. EDIT This works if you add the

问题 When I installed Git with Homebrew it shows as version 1.8.5.2 but on the website the download is for 2.0.1. Why is Homebrew installing a different version of Git? 回答1: Make sure the pre-installed git path ( /usr/bin/git ) isn't before the one installed by brew ( /usr/local/bin/git ). Check if /usr/local/bin/git --version returns the expected version. Or /usr/local/git/bin/git --version . See more at: "Homebrew installation of git won't take precedence over system version (in /usr/bin/)" "How

问题 I wrote a script without putting process.exit(0) after I looked out for the ctrl c, process.on('SIGNIT', gracefulShutdown) I want to know if the process is still running on my machine, I used: ps -aux | grep node It came up with something but i'm not sure what it is.

问题 Many terminal emulators (xterm, Konsole) support double-size characters. Ncurses does not support this and as far as I know, ncurses will not print escape characters (\033 will be unescaped and printed in clear text). Is it possible at all to print double-size characters in a ncurses application? 回答1: The "double-size" character capability you refer to is set by the following ANSI sequences (found here): ESC # 3 DEC double-height line, top half (DECDHL) ESC # 4 DEC double-height line, bottom
