• Automatically timing every executed command and show in Bash prompt?

  - by mfn

  I often happen to forget to explicitly prefix executions with the "time" command, ideally I would see in the next shell prompt how much real time the last command took (on every command). I already scoured through the bash documentation, but couldn't find anything related.

• How to activate revision info in line number view

  - by Joshua

  I know of an Eclipse feature to show revision information (gradual coloring, more info like revisionnumber, date and author on mouseover) for the last changes in a line in the linenumbers-view. Does anyone know how to activate this feature for a file, or even better, by default? I accidently hit some shortcut lately which made it show in one file, it does not show up in the others, though.

• Having trouble understanding some code (Ruby on Rails)

  - by user284194

  I posted a question awhile ago asking how I could limit the rate at which a form could be submitted from a rails application. I was helped by a very patient user and their solution works great. The code was for my comments controller, and now I find myself wanting to add this functionality to another controller, my Messages controller. I immediately tried reusing the working code from the comments controller but I couldn't get it to work. Instead of asking for the working code, could someone please help me understand my working comment controller code? class CommentsController < ApplicationController #... before_filter :post_check def record_post_time cookies[:last_post_at] = Time.now.to_i end def last_post_time Time.at((cookies[:last_post_at].to_i rescue 0)) end MIN_POST_TIME = 2.minutes def post_check return true if (Time.now - last_post_time) > MIN_POST_TIME flash[:warning] = "You are trying to reply too fast." @message = Message.find(params[:message_id]) redirect_to(@message) return false end #... def create @message = Message.find(params[:message_id]) @comment = @message.comments.build(params[:comment]) if @comment.save record_post_time flash[:notice] = "Replied to \"#{@message.title}\"" redirect_to(@message) else render :action => "new" end end def update @message = Message.find(params[:message_id]) @comment = Comment.find(params[:id]) if @comment.update_attributes(params[:comment]) record_post_time redirect_to post_comment_url(@message, @comment) else render :action => "edit" end end #... end My Messages controller is pretty much a standard rails generated controller with a few before filters and associated private methods for DRYing up the code and a redirect for non existent pages. I'll explain how much of the code I understand. When a comment is created, a cookie is created with a last_post_time value. If they try to post another comment, the cookie is checked if the last one was made in the last two minutes. If it was a flash warning is displayed and no comment is recorded. What I don't really understand is how the post_check method works and how I can adapt it for my simpler posts controller. I thought I could reuse all the code in the message controller with the exception of the line: @message = Message.find(params[:message_id]) # (don't need the redirect code) in the post_check method. But it trips up on the "record_post_time" in the create action/method. I really want to understand this. Can someone explain why this doesn't work? I greatly appreciate you reading my lengthy question.

• Visual Studio line deletion

  - by Sean

  Is there any way in Visual Studio 2003 that I can delete a line without it being copied into the clipboard? There are instances when I want to copy the first line of a block of text and then delete the following n lines but this then puts the last line I deleted into the clipboard, which is very annoying. I have come from a brief keymap background and I could easily do this with Alt-D. And while I'm on the subject, why on earth have MS stopped supporting the brief keymap?

• How to implement this UI

  - by Michael

  Just curious if the tab bar UI element in screenshots is some built in class or customized. If it is customized, then please give me a hint on what classes I might check to have something like that. The first screenshot is initial tab bar. When I tap on the last icon the tab bar smoothly(animated) resize itself as on second screenshot. If I press the edit button the icons are shaking(as on iPhone home) and I'm able to arrange them. first second

• Dubugging a program not run within the debugger and without a crash

  - by Mick

  I left a program running last night, it worked fine for about 5 hours and then one of its built-in self-diagnostic tests detected a problem and brought up a dialog box telling me the issue. The program was built with debug information (/Zi). Is it possible to somehow get the debugger started so I can examine the value of some variables within the program? Or is it too late?

  I'm in a Windows Command Line and want the parent folder in a variable. Assuming current directory is "C:\foo\bar", how can I get the value "bar"? I'm expecting something like a "find last backslash in CD and that's it". And please, no powershell references; I want plain old Windows Command Line operations.

• Does STDIN/STDOUT flush data all at once or character by character?

  - by ryeguy

  I'm using C# to read another program's STDOUT. If I do this: StreamReader reader = process.StandardOutput; reader.ReadToEnd(); Is it guaranteed to get the last thing flushed out to the program's STDOUT in its entirety? Or is kind of like TCP where I'd have to have a message terminator or length header?
