• What Patterns Should I Consider For a Html Widget Generator?

  - by DaveDev

  I'm looking to see if I can design a HtmlHelper extension method that will generate the Html for different types of widgets I want to produce. Each different type of widget implements functionality to get and prepare any data it needs to render. Can anyone suggest any patterns I could refer to for approaches to take? I know there are probably frameworks available that will do this for me, but I thought I'd give it a try anyway. Any points of advice? Thanks

• Is there a way to find a specific file and then change into the directory containing it in one go?

  - by bergyman

  I'm looking for a way to find what I know will be a unique file, and then change into the directory containing that file. Something along the lines of: find . -name 'Subscription.java' | xargs cd Or: find . -name 'Subscription.java' -exec cd {} \; I know this won't work because it's both trying to cd supplying the entire absolute path, which contains the file, and also because xargs can't do any built in shell commands...but you get the point of what I want to accomplish.

• My login controller doesn't work. Problem with fetching username.

  - by misterwebz

  Currently my login controller doesn't work because i can't seem to fetch the username and password. I'm currently using something like this: form_username = str(request.params.get('username')) db_user = meta.Session.query(User).filter_by(username=form_username) if db_user is None: return redirect('auth/error') No matter which username is use, db_user always returns True and thus never goes to auth/error. I used the shell to play with this and i was able establish a connection with the database, so i'm not sure what i'm doing wrong here.

• PHP Download File with Include

  - by arik-so

  How can I use PHP's include function to include a file and then modify the headers so it forces - at least that's how it's called - browsers to download ITSELF (the PHP file). Is it possible to also modify the preset save name, in order to change the extension from *.php to something else? Thanks in advance!

• What's the easy way to test for 304 reponses?

  - by John Mee

  I need to test if my 304 responses are working, but my development environment is pretty hard set on force no-cache. Is there an easy way to modify the max-age value of the cache-control header before it goes out? I'm perhaps a bit optimistic in hoping chrome (or an extension, or FF) has a console command letting me alter the if-modified-since header then send the request. Maybe paste something into a telnet connection?

• R language: open ssh connection

  - by marpo_it

  I am trying to open a remote shell via ssh to send commands from R. As long as I send commands, I need to get results and send new commands that depends on the output of the previous ones. For this reason I am looking for a solution to open a connection and manage it from within the R code until I have finished. I also need to open the connection with ssh key exchange (so without password authentication). Looking at CRAN I didn't find anything useful.

• What is the best way to include other scripts?

  - by Aaron H.

  The way you would normally include a script in bash is source. For example: main #!/bin/bash source incl.bash echo "The main script" incl.bash echo "The included script" The output of executing ./main: The included script The main script Now, if you attempt to execute that shell script from another location, it can't find the include unless it's in your PATH. What's a good way to ensure that your script can find the included script, especially if for instance, the script needs to be portable?

• Bash Color Variable Output

  - by drewrockshard

  I've got a variable, let's say $x and it holds the value of website.com. I want to be able to call the variable and apply shell color to it like so: echo -e '\033[1;32m$x:\033[0m'; The problem is not the color, however, it's how the script it interpretting the output. So the output I'm getting is: $x: I need the output to obviously be the string in the variable, and not the variable name. Is there any way around this issue?

• Pure python implementation of greenlet API

  - by Tristan

  The greenlet package is used by gevent and eventlet for asynchronous IO. It is written as a C-extension and therefore doesn't work with Jython or IronPython. If performance is of no concern, what is the easiest approach to implementing the greenlet API in pure Python. A simple example: def test1(): print 12 gr2.switch() print 34 def test2(): print 56 gr1.switch() print 78 gr1 = greenlet(test1) gr2 = greenlet(test2) gr1.switch() Should print 12, 56, 34 (and not 78).
