Microsoft is. Google is as it slows hiring. (In case you're looking for a date, apparently Google's recruiting team is, ahem, .) Even Apple, , is planning for life "without Jobs."
OK, so the "Jobs" in question is Steve Jobs, and he's scheduled to return to his day job in six months, but you get the picture.
The downturn is hitting open source, too. Despite, I'm hearing news of a swelling number of open-source companies that are shaving headcount, including some of the biggest names. (No, Red Hat is not one of them.)
I suppose that this was inevitable, as smart companies do smart things: when the economy tightens, these companies, along with leaders like Google and Microsoft, are going to ensure profitability.
I just regret to see good people released into the wild, and some of the people affected are very, very good (and mostly on the sales side, from what I've seen).
The point, however, is that no one is completely immune. That's not a surprise. But it is unwelcome news.
