Recent News and Commentary.  Various news media have been expecting Microsoft to release version 6.0 of the Internet Explorer (IE) this week.  I have not seen it yet on the IE page of Microsoft's web site.  This is the same version of the browser the will be in the forthcoming Windows XP, which is scheduled for release in October, but may start to appear on new computers as early as next month.

I think Gates has won the browser war unless the U.S. Government et al bring him to his knees.  I have read that 90% of the browsers in use out there are now IE.  Frankly, I hope he does OR some organization produces a universally used, standard browser (or browsers) with consistently predictable results, because designing web pages to comply with several different browser implementations is a royal pain in the neck and a huge waste of time.  IE 6.0 will most likely be THE standard.  I don't think webmasters will be doing many compatibility checks after it is in widespread use.

VIA Technology announced yesterday that they have started volume shipments of their P4X266 motherboard chipset for the Intel Pentium 4 (P4) processor.  Although SiS is trying to play catch-up and has announced that it will start sampling their SiS645/SiS961 P4, DDR333 chipset this month, the VIA chipset is the only one, including those from Intel, that will soon be widely available in shipping motherboards that will support both the P4 and Double Data Rate (DDR) Memory.

Intel currently has two chipsets that support the P4: the i850 and the i845.  The i850 marries the processor to RDRAM memory and the i845 marries it to Single Data Rate SDRAM (PC133 and PC166) memory, the most common kind of memory in use today.  As shown by AnandTech benchmarks, the first combination is faster than the P4 with the VIA chipset and DDR memory and the second combination is slower.  Because VIA does not have a license from Intel for the P4 bus interface for its P4X266 chipset and is not charging more for the chipset to pay for the license, and RDRAM is noticeably more expensive than DDR memory, while DDR memory is quickly becoming cost competitive with SDRAM, the P4X266 will enjoy a price/performance/MHz edge over the other two combinations.  At the same time DDR motherboards for the AMD Athlon and Pentium III processors are now coming on line and ramping-up.  All of this will drive DDR memory into the mainstream at an accelerated pace. 

Meanwhile, Intel has been rattling swords implying that it may take VIA to court over the licensing issue.  VIA says it doesn't need a license because of an arrangement with S3, which it says has a license (VIA bought S3's graphics business some time ago and what remains of S3 is now called SONICblue).

So, what's likely to happen?  VIA has been in licensing wrangles with Intel before and settled out-of-court.  I don't know the particulars.  It seems to me that it would be akin shooting oneself in the foot as far as processor competition with AMD is concerned if Intel proceeded with vigor against VIA before there other DDR P4 chipsets and motherboards to supply the mainstream PC market.  Therefore, it probably will not happen, if at all, until well into next year when Intel should be shipping its own P4 DDR chipset in quantity.

What does this mean?  Intel is stuck between a RamBus and an Athlon; ALi does not appear to be in the race yet; SiS is behind the curve and will add a significant premium, as will ALi, to the cost of its chipset to pay licensing fees to Intel; and VIA has almost a free reign for the next generation economical DDR chipsets for P4 motherboards used in mainstream computers.

That is, if VIA can convince first tier motherboard manufacturers to use the chipset.  Currently, they appear reluctant to do so because of the Intel threats of legal action.  Interestingly, today, VIA stated that they cannot find an Intel patent for the P4 bus.  Is there such a patent?

The processor MHz war continues and AMD is losing.  Intel has announced that it will introduce a 2 GHz version of its Pentium 4 processor on the 27th of this month.  Benchmarks have clearly shown that the 1.4 Athlon is faster in many respects than a 1.7 GHz P4; it is a more powerful processor.  Well, you can play the more powerful processor just as long as it is the more powerful processor.  A slower architecture clocked at faster and faster speeds will sooner or later overtake a superior architecture that is not.  I think 2 GHz is that point.  It will make the P4 more powerful than the fastest thing that AMD has to offer.

"MHz is a myth."  Back a few years ago Cyrix had a more powerful processor (so they said) running at a slower clock speed.  Well, it was and it wasn't.  As I recall, it did well when running business benchmarks and worse than either Intel or AMD processors when performing floating-point operations (the kind of operations that make games and other number crunching operations fast).  So, Cyrix would take their 187.5 MHz 686MX processor, for example, and give it a performance rating of PR233.  That meant that it was supposed to perform as fast as a 233 MHz Pentium, which it didn't in all scenarios, especially when playing games and synthesizing music.  The Athlon does not have these weaknesses.  Nevertheless, I think the Athlon's reputation for performance will be sullied if AMD pursues, as they appear to be getting ready to do, an advertising campaign that claims, "MHz is a myth" when it isn't entirely a myth.  "MHz" do make a difference.

Tech Tip. What is the maximum length of a printer cable?  There are two kinds widely used parallel port printer cables for PCs.  The old "standard" IBM Printer cable and the newer IEEE 1284 bi-directional cable commonly sold today.  The old IBM printer cable was a rather loose standard having its roots with cables originally designed for Centronics printers.  It was uni-directional from the PC to the printer and had a 25-pin male DB25 connector at one end and a 36-conductor male Centronics connector at the other end.  The "standard-issue" cable was six feet.  The maximum cable length was commonly stated as 15 feet.  I have operated printers with old 20-foot IBM PC cables and some, not many, PC/printer combinations will work with a quality 25-foot cable.  There are devices that can extend this length significantly.

Commonly available IEEE 1284 cables have a 1284 Type A, 25-pin male DB25 connector at one end and either the older 1284 Type B, 36-conducor male Centronics connector or the newer 1284 Type C, 36-conductor Mini-Centronics connector at the other end and are available in 6, 10, 15, 20, and 30 foot lengths. The specification also calls for various cable configurations with different connector genders.  The maximum specified length of a IEEE 1284 cable  cable is 10 Meters (approx. 30 feet) for data transfers at rates up to 2 MHz (of course, this maximum requires that the ports at both ends of the cable meet the IEEE 1284 spec as well as the cable).  IEEE 1284 cables should work with older IBM printer ports (SPP = Standard Printer Port) and uni-directional printers.  Answer: 30 feet.

Around the Internet. TCP port numbers have to be configured in a firewall or router before many Internet games, chat and conferencing services, and other applications will work.  Although one can find many lists of port numbers on the Internet, the most official list and the one that appears to be maintained more frequently is available at Internet Assigned Names Authority's web site here.  Go to FirstGov to track your Social Security benefits, apply for a federal student loan, find the nearest veterans hospital, reserve a campsite at a national park... 27 million Web pages.
