And if you've ever struggled w/ C++'s fun const-correctness, Wikipedia has a surprisingly good article on it. ]]>Sun, 29 Apr 2012 00:00:00 -04000http://www.keysolutions.com/blogs/kenyee.nsf/CommentsRSS?Open&id=11544159A844010F852579E50062AAEEhttp://www.keysolutions.com/blogs/kenyee.nsf/PostComment?RunAgent&id=11544159A844010F852579E50062AAEEhttp://www.keysolutions.com/blogs/kenyee.nsf/d6plinks/KKYE-8QNTVGAndroidKen K.

Thanks to Popa Adrian Marius who has done work getting the official AOSP working on Virtualbox, there is now a version of Android-x86 4.0.3 that has networking support.  More on how to get this working w/ Motodev Studio after the jump. ]]>Thu, 15 Mar 2012 00:00:00 -04002http://www.keysolutions.com/blogs/kenyee.nsf/CommentsRSS?Open&id=2E3EBE4EC4E10C8B8525798A007936A2http://www.keysolutions.com/blogs/kenyee.nsf/PostComment?RunAgent&id=2E3EBE4EC4E10C8B8525798A007936A2http://www.keysolutions.com/blogs/kenyee.nsf/d6plinks/KKYE-8RJ5L9LinuxKen K.

Most of the issues are from how differently it treats BYTEA (Postgresql BLOB equivalent) fields.

Oddly enough, you can also set the HTTP Request implementation to HttpClient4 and it will work fine no matter which checkbox is selected.  The checkbox should really be a radiobutton instead too, but that's a JMeter UI quirk

You also have to set the HTTP Cookie Manager to Compatibility mode (it defaults to RFC2109 which doesn't always handle cookies properly because not all web servers follow those guidelines):

When Honeycomb was first released, they released the interesting concept of Fragments (conceptually like Portlets in the web world) for developing your UI.  This made it harder for app developers because they would have to build a separate tablet version of their app and a different phone version of their app since this new API wasn't for older phone based Android versions.  Google released the promised Android Compatibility Library (ACL) that was meant to address the lack of Fragments API in phone apps, however, this library isn't complete for all the common UI features in Honeycomb.  Most notably, the very useful ActionBar (conceptually like a toolbar in desktop apps) is not supported, so you almost have to rip all the support out of your code to get it to compile for phones, unless you use AndroidBarSherlock which Jake Wharton was nice enough to build on top of ACL (though it doesn't support ActionMode which let you make the ActionBar context sensitive). ]]>Sun, 14 Aug 2011 00:00:00 -04001http://www.keysolutions.com/blogs/kenyee.nsf/CommentsRSS?Open&id=35B7C6BBF7203F5D852578E900660E0Ahttp://www.keysolutions.com/blogs/kenyee.nsf/PostComment?RunAgent&id=35B7C6BBF7203F5D852578E900660E0Ahttp://www.keysolutions.com/blogs/kenyee.nsf/d6plinks/KKYE-8KDP7HWindowsKen K.

After the first Windows Update, you can also delete all the files out of the download cache which is in \windows\SoftwareDistribution\Download (why Windows doesn't do this automatically after it installs them, I have no idea)-:
If you had IE installed (not installed if you installed Core server), you can also disable IE ESC by doing "“\Windows\system32\rundll32.exe” \Windows\system32\iesetup.dll,IEShowHardeningDialog" to bring up the dialog or you can do it the hard way by mucking with the registry.  If you don't do this, you get all sorts of aggravating behavior like not being able run executables off a network share, not being able browse any untrusted sites, etc.  Unfortunately, this doesn't affect .msi files which cannot be run off network shares.
And if you don't want to remember all the arcane (yes, arcane, and I'm very used to using Linux so I actually like command line tools) Win2008 Core commands, you can grab CoreConfigurator to make your life easier.  Win2008 Core isn't really command line because it brings up the graphics subsystem).
Install vim (add it to the path by modifying the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment), wget and KpyM SSH and allow ssh through the Windows Firewall (netsh advfirewall firewall add rule name="SSH" dir=in action=allow protocol=TCP localport=22) and you're all set for remote admin of a minimal server.
