Here is something that I had to find the moderately hard way:
When used on an NFS filesystem, Linux's
umount -fwill force anyoutstanding IO operations to fail with an error, whether or not theunmount will succeed.
This can be both good and bad, but on the whole I think it's mostly bad.
If the NFS server has died completely and the outstanding IO can neversucceed, you do want things to abort now instead of hanging around. Inthis case umount -f '
The weird effects of Firefox's remote control on Unix
I hope that Firefox's remote control feature is reasonably well known,but I suspect most people don't know about the surprising and relativelyweird effects it has in the Unix version of Firefox; certainly itsurprised my co-workers when they stumbled across it.
(Remote control is the feature where if you already have a runningFirefox and try to start another one, it will just open a new browserwindow (or tab) in the first one.)
The root of the surprising behavior comes from how

Why I believe that you want Solaris if you want ZFS
As Wolfgang Lonien recently pointed out , Solaris isn't the only systemwith ZFS, as you can also get it in at least FreeBSD. Despite theseports, I believe that Solaris generally remains your only solid choiceif you need ZFS.
The problem is that ZFS is currently incomplete, with both missingfeatures and significant problems . Thismeans that the work of integrating ZFS into other systems is notcomplete, and there are two potential issues with the remaining work.
The first is the most straightforward: you are taking

全世界都趕在農曆年前後向聯交所入A1表。這陣子,凡是有IPO deal在手的都忙得頭昏腦脹。看看日曆,shit!原來已是一月中,我白白錯過了今年的Christmas sale!
