• writing a program to ban a user (by MAC address) from a network

  - by Gail

  I'm not sure if this is possible at the application layer. Can a program be written to read and analyze packets (maybe interfacing with wireshark through it's lua api) and ban MAC addresses with suspicious network traffic?

• How to switch from MSSQL to MySQL for using with Excel pivot

  - by Sim

  Hi all, I have a table that contains sales transaction (~20 mil rows). Previously I used MSSQL and export it to an Excel pivot. Data refresh took 10-15 minutes but still do-able. However, after I migrated to MySQL (using XamppLite & ODBC), it took forever to refresh the data in the Excel pivot. Maybe I didn't optimize the MySQL good enough ? Anyone can share some thoughts 'bout this ? Thanks

• Ruby on Rails, autocomplete => "off" in text input fields, not working on Firefox

  - by dt

  I have both a text_field and a text_area in Rails, and I want to disable the browser's auto-complete. Setting the attribute in either the text_field, text_area, or in the form itself, doesn't seem to make the browser stop trying to auto-complete. This is for Firefox 3.6.3 on OS X. Maybe it's more a browser issue than a RoR issue. Thanks!

• How to install VS.NET 2010 without Team Explorer

  Since we don't use and don't plan to use TFS, it would be nice to not install Team Explorer VS.NET addon and not see any references to it. However this is no TFS option in customized install.

• Standard Practice for Continuous Integration of Maven Multi-module projects

  - by James Kingsbery

  I checked around, and couldn't find a good answer to this: We have a multi-module Maven project which we want to continuously integrate. We thought of two strategies for handling this: Have our continuous integration server (TeamCity, in this case, but I've used others before and they seem to have the same issue) point to the aggregator POM file, and just build everything Have our continuous integration server point at each individual module Is there a standard, preferred practice for this? I've checked Stack Overflow, Google, the Continuous Integration book, and did not find anything, but maybe I missed it.

• Web-serving a file : Firefox truncates name

  - by interstar

  I'm serving a file from Lighttpd whose name contains space-characters. I'm using mimetype "application/octet-stream" When I download this in Chrome, it works perfectly. But when I download in Firefox, the filename is truncated at the first space. Is this to do with the mimetype? With some other lightty config? Or maybe something to do with the kind of space-character I'm using?
