ZDNet at 9,600 bits per second (and we liked it)

It was 1991, and only academics, researchers, and the military were on the Internet. For most people, going online meant connecting with a v.32 modem, at the blazing speed of 9,600-BPS (bits per second) to a Bulletin Board System (BBS) or an online service. The most popular of these services was CompuServe and so it was that Ziff Davis, them the publishing company parent of ZDNet, decided to start its own mini-online service, ZiffNet, on CompuServe, and I was there.

Under the CompuServe/ZiffNet ID, 72441,464 and then, as now, one of ZDNet’s most prolific writers, I was writing on the online discussion forums, helping to manage them as a “sysop,” and doing some trouble-shooting. You, if you’ve come to the online world since the Web arose a few years later, would barely recognize 1991’s ZiffNet.

For starters, everything was text-based. Oh, someone might post a message with ASCII-art from time to time, but that was it. That isn’t to say though that you could read stories on CompuServe/ZiffNet. At first, you couldn’t. All you could do is “talk” with each other and Ziff writers and editors on the various publication forums, such as Computer Shopper, PC Week (later eWEEK), and PC Magazine. These publications live on but no longer have any direct connection with ZDNet.

We also boasted an online forum for executives, Executives Online, or in CompuServe terms: ZNT: EXEC. There, Esther Schindler, noted writer, editor and sysop supreme, would host technology industry movers and shakers as they would ‘talk’ to forum members.

It’s official: Asia’s just ran out of IPv4 Addresses

Well, that was fast. The Asia Pacific Network Information Centre (APNIC) has just released the last block of Internet Protocol version 4 (IPv4) addresses in its available pool. We knew this was coming when the Internet Corporation For Assigned Names and Numbers (ICANN) and the Internet Assigned Numbers Authority (IANA http://www.iana.org/) announced in February that the last of the world’s remaining IPv4 blocks had been assigned to the Regional Internet Registries (RIR). What we didn’t know was that APNIC would run out quickly. I, and most other people, thought that its supply of IPv4 addresses would last until at least early summer. We were wrong.

In a statement, ASPNIC announced that, “This event is a key turning point in IPv4 exhaustion for the Asia Pacific, as the remaining IPv4 space will be ‘rationed’ to network operators to be used as essential connectivity with next-generation IPv6 addresses (PDF Link). All new and existing APNIC Members who meet the current allocation criteria will be entitled to a maximum delegation of a /22 (1,024 addresses) of IPv4 space. ”

So what happened? APNIC Director General Paul Wilson explained the Asia Pacific region is the first to reach the point of being unable to meet IPv4 demand. This is due to the unprecedented fixed and mobile network growth the region is experiencing.

SCO is dead, SCO Unix lives on

SCO, the anti-Linux lawsuit monster is dead. There are still twitches left in the corpse in the bankruptcy court morgue, but when even Groklaw retires from the field, you know SCO’s as dead as a doornail. But, SCO’s Unix operating systems, OpenServer and UnixWare, will live on under the aegis of a new company, UnXis.

This has some people, including Pamela Jones, editor and founder of Groklaw worried that UnXis might follow in SCO’s lawsuit crazy tracks. “Targeting end users? Uh oh. That has a creepy sound, considering the heritage of SCO, if you know what I mean.”

I didn’t think anyone with a lick of sense would try to re-tread SCO’s hopeless lawsuits, but then I’d thought from the very start that SCO taking on IBM, et. al. in the courts was a suicidal move. So, I asked the UnXis’ CEO, Richard A. Bolandz, what his plans were.

Bolandz replied, “UnXis has no intention to pursue any litigation related to the SCO Group assets acquired by the company. We are all about world leadership in technology not litigation.

Twenty Years of Linux according to Linus Torvalds

The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, started the celebration of Linux’s 20th anniversary at the Linux Foundation Collaboration Summit, but when is Linux’s real birthday? Is it August 25th, when Linus announced the project? October 5th 1991, when 0.02, the first public release was made? I decided to go straight to the source and asked Linux’s creator, Linus Torvalds.

SJVN: “What’s Linux real birthday?” You’re the proud papa, when do you think it was? When you sent out the newsgroup post to the Minix newsgroup? When you sent out the 0.01 release to a few friends?

LT: I think both of them are valid birthdays.

Cisco: Back to Business

When Cisco CEO John Chambers said that the company had lost its way and that he was going to re-target the company, he wasn’t kidding. Today, April 12th, Cisco has shut down its popular Flip video camera business and is integrating its umi consumer videoconferencing and Eos media solutions into its business video offerings.

While some business people, such as Brian White, a Ticonderoga Securities analyst, liked this news “The Street never fell in love with Cisco’s consumer strategy and the Flip product line was the epitome of this disdain,” White wrote in a research note. Many other people have been telling me how much they’ll miss the Flip video camera. After all, the Flip created a whole genre of hand-held video cameras.

I know a lot of people are really upset about Cisco bringing down the curtain on Flip. But, with the rise of video-camera equipped smartphones, others didn’t think the Flip could have made it no matter what Cisco did with it.

Google speeds up the Web with SPDY

Network engineers and hard-core Web architects know that HTTP (Hyper Text Transfer Protocol), the data transfer method used by the Web, isn’t the most efficient data transfer protocol around. So, back in November 2009, Google started working on a faster replacement: SPDY, pronounced “speedy.” And, now, if you’re using the Chrome Web browser, and visiting Google Web sites, you can see SPDY in action according to Conceivably Tech.

I’m inclined to believe these claims because when I opened some moderately complex spreadsheets in Google Docs using both Chrome 10 and Firefox 4, and taking into account their differences in JavaScript rendering speed, Chrome 10 was still rendering pages about 20% faster than Firefox from what I would have expected.

I saw similar results on Gmail, iGoogle, and Google Advanced Scholar Search. I don’t know about you, but a 20% boost in Web site performance is impressive to me.
