Selecting ?Your Laptop
Dimensions and Weight (4 to 10 pounds) Display (12 to 16 inch size, 15 optimal, Resolution) Optical Drives (CD-ROM, CD-RW and CD-DVD ROM combo, CD-DVD RW) Hardrives (30 to 80GB, 4,200 to 5,400 RPM) Memory (256 Min, 512 Optimal, 1024 Max) Main Processor (CPU)
Reworked Desktop Processors
Truly Mobile (Built from Ground Up)
Graphics Processor
Dedicated Video Memory (8 to 32MB common for mobile) Shared Memory for Desktops Gamers should look for at least 4X AGP
Communications Features (56K modem, Ethernet, Wireless) Ports (USB 2.0, Firewire, Multimedia) Battery (Lithium Ion, 2 hours minimum life, 4 hours optimal, Greater than 5 nirvana)
Building the Mobile Chip from the Ground Up (Two Approaches)
Transmeta Crusoe
Very Long Instruction Word (VLIW) instruction set Code Morphing Software Interface to match x86 commands to VLIWArchitecture permits a significant reduction in transistors and power First new chip architecture in years Slower than Pentium M?.but uses less power
Intel Pentium M (code name Banias)
Developed by Isreali design team that worked on the failed Timna project Modified Architecture
Pipeline shorter than P4 longer than P3 Micro operations fusion for better pipeline utilization and higher IPC Better Branch Prediction than P3 Better stack management Large 1MB L2 cache with low power access method
Higher Instructions per Clock Cycle (IPC) 1.3 GHz P-M equal to 2 GHz P4 Impressive performance?achieves both low power usage and high processing speed
Ultra portables and portables with long battery life use either Crusoe or Pentium M
Intel?s Dilemma Making the Slower Clockspeed Pentium M Attractive
Centrino, a product suite, is the marketing angle
Low Power Processor
Pentium M (1.3 to 1.6 GHz)
Low power chipset 855 for the motherboard
855PM is a discrete memory controller hub 855GM Chipset included integrated graphics
Integrated Wireless (the weakest of the centrino suite)
Clock speed is not discussed?..mobile power computing with wireless networks and long battery life are. That renegade Intel Israeli design team has done a good job?.
Quick Overview of Laptop Market What is in your Dell anyway?
Acer reveals that it is a major supplier of Dell parts Dell does not make it own parts It assembles them A superb supply chain management system
Who Profits from Spam Anyway?
Juan Garavaglia, (aka Zuper Zonda) sends out 30 to 40 million spams/day
In one case he collects mortgage information Sold to Ameriquest, Quicken Loans, LoanWeb, Ivy Mortgate They bought the leads from a lead generator Leads are resold before they reach the final customer Yourleadsource.com in Colorado is one middle man (affiliate)
Another spam use is traffic driving
Affiliates paid for each click through Span used to generate click throughs Target site does not spam
ISP Make Money Too
Recent bankruptcy of spammer, Ron Scelson, showed Bell South (56K) and Cable & Wireless (4K) Three years ago, AT&T and PSINet were both caught with spammer deals where they sell bandwidth well above normal rates (so called Pink Contracts)
Even organ enlargement spam is profitable
Amazing Internet Products from New Hampshire Recently customer list was stolen and publisher Braden Bournival 19 year old owns company His is also VP of the New Hampshire Chess Association Sister stuffs the envelops Grosses?500K/month from one affiliate (Goringly.biz)
