Apple = 11xDell’s market value

On October 6, 1997, in response to the question of what he'd do if he was in charge of Apple, Dell founder and CEO Michael Dell stood before a crowd of several thousand IT executives and answered flippantly, "What would I do? I'd shut it down and give the money back to the shareholders."

A little more than a month later, on November 10, 1997, new Apple Interim CEO (iCEO) Steve Jobs responded, speaking in front of an image of Michael Dell's bulls-eye covered face, "We're coming after you, you're in our sights."

On January 13, 2006, after a little more than eight years of hard work, Apple Inc. passed Dell, Inc. in market value, $72.13 billion vs. $71.97 billion at market close, respectively.

  • 9X: On June 1, 2010, Apple gained $6.89 to $263.77 to hit a market value of $240.01 billion or more than 9 times that of Dell's current $26.29 billion.
  • 10X: On September 9, 2010, Apple gained $1.60 to $265.37 to hit a market value of $242.43 billion or more than 10 times that of Dell's current $24.21 billion.

Apple is also a debt-free company and currently has significantly more cash and short-term investments on-hand ($46 billion) than Dell Inc. is worth (now nearly double, in fact).

Route Preference


Suppose a router receives a packet destined for the IP address 192.0.2.73. The router has in its routing table the following three routes:
ProtocolADMetricPrefixNext Hop
OSPF110240192.0.2.0/25172.16.1.1
EIGRP9033789192.0.2.0/24172.16.2.1
RIP1206192.0.2.64/26172.16.3.1
To which next hop address will the packet be routed?
If you picked 172.16.3.1, you're correct. Why? A router evaluates routes in the following order.
  1. Prefix Length - The longest-matching route is preferred first. Prefix length trumps all other route attributes.
  2. Administrative Distance - In the event there are multiple routes to a destination with the same prefix length, the route learned by the protocol with the lowest administrative distance is preferred.
  3. Metric - In the event there are multiple routes learned by the same protocol with same prefix length, the route with the lowest metric is preferred. (If two or more of these routes have equal metrics, load balancing across them may occur.)

Speed Up SATA Hard Disk Performance with AHCI

The Advanced Host Controller Interface(AHCI) will speed up read and write operations of the hard drive if the hard drive supports AHCI.


AHCI includs a PCI BAR (base address register) to achieve the native SATA function. As the AHCI successfully develops a unified interface,allow the Serial ATA product development work greatly simplified. It can achieve a number of features including NCQ (Native Command Queuing).

This is a tip to enable AHCI at the boot level to speed up the performance of your SATA disk.

  1. Start your registry with "regedit".
  2. Browse to the "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci"
  3. Locate the parameter "Start" on the right side.
  4. Double click it to change its value from 3 to 0.
  5. Restart the computer.

Fix Slow Network Copy in Windows 7

TCP Task offloading to Network Interface Card (NIC) means transferring certain tasks such as Checksum calculation on Header or data Tunnel Encryption and so on from system processor to NIC. This boots the performance of the system as the processor is freed from the overhead of such tasks.

Disable it may help to you fixed slow network copy and connection drops in windows 7. There are 2 ways to set this setting.


  • Start "cmd" in "Administrator mode".
  • Run the following command to check the enabled offload tasks.
C:\Windows\system32> netsh int ip show offload
  • Run the following command to disable all Task offloads.
C:\Windows\system32> netsh int ip set global taskoffload=disabled
  • If it displays "OK" means you have disabled all the offloads.
  • Disable the NIC and Re-enable it to refresh the setting.
Another way to disable it is via Registry.
  • Start "regedit"
  • Browse to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters"
  • Create or select the "DisableTaskOffload" (DWORD) and set it to:
1 : Disable task offload.
0 : Enable task offload.

How to Bridge Windows Virtual PC (Windows 7) to use Host Computer Wireless Network

If you are using Windows Virtual PC in Windows 7, you may notice that the Windows Virtual PC is different than the Virtual PC 2007, because it can't use the host computer wireless connection for bridging. This problem can be easily solved by switching VMware player/workstation/server.

If you are looking for the solution for your Virtual PC 2007, see here. Here, I'll show you how I hack Windows 7 to make this work in wireless network.
  1. Create and start wireless hosted network in Windows 7. See the detail here.
  2. Enable (host) wireless adapter to allow ICS for MS Virtual WiFi Miniport Adapter. See the detail here if it is disable by network administrator.
  3. At your Virtual PC, Set "Networking Adapter" to use "Microsoft Virtual WiFi Miniport Adapter".
Now, your Virtual PC should start getting a new IP address from DHCP, and should be connecting to network like using the wired network (Ethernet).
