From previously-cited writer comes yet another ‘killer essay’.

if (Windows Rules) then (Linux fails)

Part of the problem with the documentation and identification issues I talked about last week – and will talk about more later – is that it is very hard to separate information from disinformation.

Disinformation comes in three major forms:

1. innocent mistakes;
2. intentional disinformation (aka FUD); and,
3. (self) delusion.

AID stands for Redundant Array of Independent (or Inexpensive) Disks. As yet, I find RAID somewhat redundant, at least in my individual scenarios and for my personal purposes.

RAID is associated with backups on multiple disks, which in turn enables easy data recovery. The disks may also be distributed across geographically isolated and thus independent places. RAID does not directly cater for synchronation of data, applications, settings. That, for instance, is one of the powers of on-line services and network-hosted environments. This, as a matter of fact, is what pushes computers towards becoming relics.

One question to consider in RAID is the target of a write/read operations. This point refers to where data should be fetched from or save onto and how changes should propagated among the multiple disks. These issues are easily resolved in the following way:

Let us look at this conundrum, which is flawless management of files across computers. The confusion over where data gets stored and fetched from can be resolved owing to remote login. Assuming we speak of high-bandwidth networks here (100Mbit LAN in my case), the ‘cost’ of using SSH bandwidth is almost negligible. Even 10Mbit connections would give you a very responsive UI behaviour over the network. I know this because I tried it. The exception are cases where you stream many large frames over the network (e.g. video, games).

I have never looked deep into RAID technologies. Why not just scp (or rsync) the entire content of a hard-drive periodically? I maintain files on just a single machine, which I always SSH to from elsewhere. Its contents get mirrored on two other remote machines. Files that change on a daily basis are backed on the SAN overnight using cron jobs. This simplifies life a great deal. I still see no compelling reason for using RAID, especially with the existence high-speed networks.

As for Web site backups, these can conveniently be downloaded unless an automated job is set up, which is something I hope to do one day.

ARGE quantities of Red Hat-based terminals are expected to reach the African people. This comes a month or two after Microsoft refused to give Africa cheaper software, arguing that skills were needed rather than more software.

South African news site Tectonic is reporting how KDE terminals are Giving South African Farmers a Leg-up.

The government’s IT manager said “People’s perception of open source is that everything is command-based, text-based. Our pilot projects are meant to address that perception.”

INUX distributions and their great diversity lead to endless discussions at best and flame wars at worst. Because they all incorporate the same kernel, they can be equated to beer from different brands (the infamous beer analogy). Each person, however, will try to convince you that his/her favourite beer is distinct and superior to all others.

A survey was conducted by ZDNet, which aimed to identify the best Linux distribution for a small business. Among the options that have been put to the test: Mandriva Linux 2006, Novell Linux Desktop 9, Red Hat Desktop 4, SUSE Linux 10 and Ubuntu Linux 5.1. The outcome:

We emerged from our Linux experience with a strong preference for Ubuntu Linux 5.1, with SUSE Linux 10 a close second. Both did everything we required of them, and both have very low setup costs. Ubuntu, in particular, costs absolutely nothing to purchase.

Interestingly enough, Ubuntu and SuSE have naturally become my preferred distributions. At some stage, I had 2 Ubuntu boxes and one preloaded with SuSE, but I now have 2 SuSE boxes and one which runs Ubuntu. One wonders if the crucial factor which is cost could have put SuSE at the very top rank. OpenSuSE can definitely make the exception in due time.

CCESS to particular computers can be crucial, especially while travelling. There are a variety of ways for achieving full remote access, though simple, text-based shell access is supported by even weaker devices and light-weight software.

I recently read about someone who thought of handling Web servers from a Palm Treo, using E-mail, which is supposedly a universal API. I consider E-mail to be the wrong tool for a simple task, even if one uses cron jobs and collects the output via E-mail (similar to a hack I once mentioned. Alternatively, shell access can be obtained in one of the following ways:

• Cellular telephones: using CUTs
• Web-based: MindTerm, e.g. from Duke University
• Windows: PuTTy
• Windows mobile: I have seen an SSH client in action and it looked quite clean
• UNIX variants and derivatives: Built-in functionality
• Palm O/S: pssh, free and apparently based on PuTTy, though it is hard to tell for sure
• Blackberry: For that, one might have to pay nearly $100. That’s the chance one takes when steering away from Open Source. Palm may not be Open Source-oriented, but its users’ ideaology differs.

RedHat Linux

previously mentioned the $100 laptop initiative and repeatedly referred to cheap computers in general. An article in the Wall Street Journal now claims that the $100 laptop is nearing reality. It will supposedly run Red Hat Linux on AMD processors.

A novel plan to develop a $100 laptop computer for distribution to millions of schoolchildren in developing countries has caught the interest of governments and the attention of computer-industry heavyweights.

Steve Jobs, Apple Computer Inc.’s chief executive, offered to provide free copies of the company’s operating system, OS X, for the machine, according to Seymour Papert, a professor emeritus at MIT who is one of the initiative’s founders. “We declined because it’s not open source,” says Dr. Papert, noting the designers want an operating system that can be tinkered with. An Apple spokesman declined to comment.

Microsoft released a report that is very damaging to the image of their operating system. As Paul Murphy from ZDNet put it, ‘Unix beats Windows’ – says Microsoft!.

What’s noteworthy about it is that Microsoft compared Singularity to FreeBSD and Linux as well as Windows/XP – and almost every result shows Windows losing to the two Unix variants. For example, they show the number of CPU cycles needed to “create and start a process” as 1,032,000 for FreeBSD, 719,000 for Linux, and 5,376,000 for Windows/XP.”

Microsoft are still trying to defend their new operating system called Singularity, but in the process they lead to public confusion and doubt. As we approach the release of Windows Vista (due next year), the Gartner group suggests that Vista should be ignored until 2008.

Companies shouldn’t rush to upgrade to Microsoft Windows Vista, according to analysts at Gartner, who believe most firms could safely hold back until 2008.

The majority of improvements in Vista will be security-related and most of this functionality “is available via third-party products today”, Gartner claimed in a research note published on Friday.
