• Does EGit mandate installing JGit?

  - by Souper

  After using Git from the command line for a while, I am ready for the convenience a GUI plugin (for Eclipse) can offer. However, I prefer a Git plugin similar to to MS Visual Studio's Git Source Control Provider which is only a wrapper around the already installed msysgit. I really don't want two different Git implementations accessing the same repository. EGit sounds perfect - if it can use the already installed msysgit in my PC. But can it?

  - by Trevor Burnham

  I was just digging through some JavaScript code (Raphaël.js) and came across the following line (translated slightly): Math.min.apply(0, x) where x is an array. Why on earth would you do this? The behavior seems to be "take the min from the array x."

• Dealing with &rest-parameters in common lisp

  - by Patrick

  I want define a functions that accepts &rest - parameters and delegates them to another function. (html "blah" "foo" baz) = "blahfoobaz" I did not find a better way than this one: (defun html (&rest values) (concatenate 'string "" (reduce #'(lambda(a b) (concatenate 'string a b)) values :initial-value "") "")) But this looks somewhat glumbsy to me, since line 4 does no more than concatenating the &rest parameter "values". I tried (concatenate 'string "" (values-list values) "") but this does not seem to work (SBCL). Could someone give me an advice? Kind regards

• Are there any programmable barcode scanners that can call a webservice?

  - by Mark Redman

  I am looking at integrating a C# application with a barcode scanner. The last time I did this was with Delphi 1 (win 3.11) using a scanner that plugged in-line into the keyboard cable. Looking around it appears most scanners are USB based these days and assume they emulate keyboard entry. Anybody know of more sophisticated/programmable scanner that can call a webservice or even just do a basic POST/GET this would eliminate the C# application and the computer to support it?
