trivial detail in facebook messenger

2011-12-31 11:23

I download facebook messenger from here. After install I found something interest.

First it's a C++ managed CLR program. I think running on Win8 is their main purpose.

Then I noticed it use a several open source library almost all from Google.

• omaha: Google open source for auto update, a complicate weapon.
• breakpad: crash report and dump analytics tools from Google, I really love it.
• gtest: Google unit test library. Unit test is rarely seen in windows applications, I believe It's high quality
• gecko: core of firefox from mozilla.org, It's a wise choice.

about certification signing:

• FacebookMessenger.exe not signed.
• FacebookUpdate.exe signed.
• FacebookCrashHandler.exe signed.

Sadly, I never saw the interface, because it(verion 2.0.4373.0) keep quit abnormally on my winxp.

Whatever, it's absolutely above average in Windows application technology.
