Pfizer to lay off 10,000 people

Pfilzer will cut 10K people. Yes, I know it is not an IT company, but

  • IT industry depends on other industries. For example, consider how many computers, network equipments, and storage Pfilzer need to buy and manage.
  • I like one guy said here “You can’t cost-cut your way to prosperity,”. We saw soooo many cut, lay-off, reduce in workforce, restructure, in IT industries. But will this really heal the problem and lead to prosperity? ;)

Zero-copy user space page access from Linux kernel

Recently we discussed about this SCST user space device handler, so fast accessing user space page become a key factor to success. Lucky we have this already.

Full disk encryption

Last night had a good time when watched 24 from FOX. One scenario is that some highly useful information was recovered from an exploded laptop hard drive. After equipping with all fancy high technologies, they still forgot to do FDE. Just being curious, I should google and see how fast a computer forensicist can deal with an AES encrypted hard drive. Can he/she do it in 24 hours? ;)

PCI latency timer

Seems hard to find some information about how to tune PCI latency timer for maximum performance. So try to dump what I can find.

Here is a detailed introduction about it. This book has some information about it as well.

Linux kernel has a document about tuning Chelsio NIC. Also here about S2IO NIC. Seems these NICs just want to take maximum 248 value and hold bus as long as possible.

Brocade bought Sliverback

Detailed news can be found here. Though we do not know how much Brocade paid. But the news said this

“Brocade did not say yesterday how much it paid for privately held Silverback, but said it was “not material,” meaning it’s not enough money to have to be reported to shareholders.”

So it is a small money. Or means Sliverback is not a successful start up. But the iSCSI HBA from Silverback is nice. I tried one back in 2004 and it is blading fast. Again, good technology means not much… :P

Virtual ROM support

Recently I added a virtual ROM support to IET, details can be found here. One simple use is to export various OS installation ISO to ESX or Xen, so you can install OS easier.

Next step is to allow ISO files dynamic “ejected” and “loaded”, and a virtual DVD writer support. The code is done, just need to be polished. A fun but illegal use of this code is to clone a DVD .. to system as a ISO file, then you can watch it later at any time. Of course, when you have XVID and VIDX, you don’t need that right? ;)

Seriously, this can be used as WORM archiving purpose. Or do a disk staging for D2D2H.
