Given that it's Veteran day, and the term "foobar" is thought to be borrowed from military term "FUBAR," I am guessing that it is Google's attempt to recruit Tech-savvy Veterans.
In the article you linked to, there is even a short discussion of the possible connection between "foo bar" and FUBAR. If your comment was meant as a rebuttal, it failed.
There is this no nonsense, star faculty in the department where I did my undergrad.
Urban Legend in the department says that in one of the offerings of his classes, there was this smug student, who would chime in, and comment on the material being presented at every chance he got.
One day, while the faculty was presenting a particularly tough topic material to the class, the smug student raised his hand and asked, "Would it be OK if I ask a stupid question?"
The faculty looked at the student's face, grinned and said, "It is perfectly fine. After all, there is nothing such as stupid question." He paused for a bit, and then completed his sentence. "But there is only such a thing as stupid student."
What was funny to me was that the author claimed, "Ah, those are just silly, throw-away apps I developed for my kids and friends." at the start of the article, and then jumped to, "I dedicated $500,000 worth of my efforts on these apps!" later on in the article. Well, that escalated way too quickly ....
Also, what is that statement that amounts to "Nobody uses Android in San Francisco"? I found it pretty ridiculous ....
If I do not know any better, the first thought that would come to my mind would be: "Wow, this company has really messed-up code base, and people here cannot even get linked-list done right. Do I really want to work here?"
