  • Pass variables between separate instances of ruby (without writing to a text file or database)

    - by boulder_ruby
    Lets say I'm running a long worker-script in one of several open interactive rails consoles. The script is updating columns in a very, very, very large table of records. I've muted the ActiveRecord logger to speed up the process, and instruct the script to output some record of progress so I know how roughly how long the process is going to take. That is what I am currently doing and it would look something like this: ModelName.all.each_with_index do |r, i| puts i if i % 250 ...runs some process... r.save end Sometimes its two nested arrays running, such that there would be multiple iterators and other things running all at once. Is there a way that I could do something like this and access that variable from a separate rails console? (such that the variable would be overwritten every time the process is run without much slowdown) records = ModelName.all $total = records.count records.each_with_index do |r, i| $i = i ...runs some process... r.save end meanwhile mid-process in other console puts "#{($i/$total * 100).round(2)}% complete" #=> 67.43% complete I know passing global variables from one separate instance of ruby to the next doesn't work. I also just tried this to no effect as well unix console 1 $X=5 echo {$X} #=> 5 unix console 2 echo {$X} #=> "" Lastly, I also know using global variables like this is a major software design pattern no-no. I think that's reasonable, but I'd still like to know how to break that rule if I'd like. Writing to a text file obviously would work. So would writing to a separate database table or something. That's not a bad idea. But the really cool trick would be sharing a variable between two instances without writing to a text file or database column. What would this be called anyway? Tunneling? I don't quite know how to tag this question. Maybe bad-idea is one of them. But honestly design-patterns isn't what this question is about.

  • possible to change a script when it is running?

    - by Daniel
    Suppose a script has 1000 lines, and the 10 line has a command takes a long time to run and when I find it is running line 10, I find I need to change line 100, is it possible to do that without stop the script first? We can also stop a process by using command pstop, but I don't know how to let the process to re-read the script and continue to run from where it paused.

  • Load php file wth xml header

    - by John Smith
    I have a php file with an xml header and xml code, named test.php. How do I load this file as an xml? The following doesn't work: $xml = simplexml_load_file('test.php'); echo $xml; I just get a white page. The test file is saved as php, as it's dynamic. It's loading data from the tradedoubler api. The xml looks something like this: <voucherList> <voucher> <id>115</id> <programId>111</programId> <programName>Program 111</programName> <code>AF30C5</code> <updateDate>1332422674941</updateDate> <startDate>1332370800000</startDate> <endDate>1363906800000</endDate> <title>Voucher number one</title> <shortDescription>Short description of the voucher.</shortDescription> <description>This is a long version of the voucher description.</description> <voucherTypeId>1</voucherTypeId> <defaultTrackUri>http://clk.tradedoubler.com/click?a(222)p(111)ttid(13)</defaultTrackUri> <siteSpecific>True</siteSpecific> </voucher> <voucher> <id>116</id> <programId>111</programId> <programName>Program 111</programName> <code>F90Z4F</code> <updateDate>1332423212631</updateDate> <startDate>1332370800000</startDate> <endDate>1363906800000</endDate> <title>The second voucher</title> <shortDescription>Short description of the voucher.</shortDescription> <description>This is a long version of the voucher description.</description> <voucherTypeId>1</voucherTypeId> <defaultTrackUri>http://clk.tradedoubler.com/click?a(222)p(111)ttid(13)url(http://www.example.com/product?id=123)</defaultTrackUri> <siteSpecific>False</siteSpecific> <landingUrl>http://www.example.com/product?id=123</landingUrl> </voucher> </voucherList>

  • Are there any C++ style and/or standard example files available?

    - by Harvey
    While there are lots of questions about coding style, beautifying, and enforcement, I haven't found any example C++ files that are used as a quick reference for style. The file should be one or two pages long and exemplify a given coding standard/style. For example, the Google C++ Style Guide is a great reference, but I think a one to two page piece of code written in their style pinned to a wall would be more useful in day-to-day use. Do any of these already exist?

  • Swing: easiest way to align width of [dynamic][static][dynamic] components?

    - by java.is.for.desktop
    What is the easiest way in standard Java Swing to align three components in such a way that: the dynamic widths of Component1 and Component3 are adjusted to be equal, while Component2 (which is in between) has constant width? Imagine we have some resizable JPanel (such as inside a JFrame). Small width should look like this: [----------------whole JPanel----------------] [--Component1--] [Component2] [--Component3--] Big width should look like this: [------------------------whole JPanel------------------------] [------Component1------] [Component2] [------Component3------] Note: I just "trialed-and-errored" with GroupLayout for too long.

  • Put `stdout` in an `NSTextView` while running the a command

    - by Koning Baard XIV
    I'm creating a Cocoa Application, which will need to run the rails command. This command generates an output, and streams it to stdout. I want to show this output to the user in an NSTextView (so basicly stream the stdout to the NSTextView). I don't really care about how I should run the command, as long as I can set the working directory. Can anyone help me? Thanks

    I have a method like: public T Get<T>(string key) { } Now say I want to return "hello" if the type is a string, and 110011 if it is type int. how can I do that? typeof(T) doesn't seem to work. I ideally want to do a switch statement, and return something based on the Type of the generic (string/int/long/etc). Is this possible?

  • netServiceBrowserDidStopSearch not called

    - by user263569
    I'm now writing a Bonjour service listener class, according to the document here: Currently, it seems working, I can receive "netServiceBrowserWillSearch:" and "didFindService:moreComing:" correctly. However, after a long wait, I cannot receive " netServiceBrowserDidStopSearch:" or "netServiceBrowser:didNotSearch:". Therefore I don't know that is the proper time for my delegate class to stop showing some UI. Could anyone have an idea for this? Thanks.

  • Is there a good GUI SVN app for Mac (better than XCode)

    - by Lawrence Johnston
    Hey everybody, I'm looking for a more robust and fully featured GUI SVN manager for Mac than what is built into XCode (which works, but only as long as you don't need anything beyond the bare basics and doesn't work for versioning scripts and such created in other editors). I can use the terminal commands, but I'd really like the option of using a GUI. On windows I use TortoiseSVN and Visual SVN, which do pretty much everything I need, but as far as I'm aware there's nothing even remotely resembling those on the Mac side.

How to do this in ASP.NET MVC 2? I will be grateful for helpful responses.
