Stop piling on Mono already

I have no love for Microsoft, most of its products, and nothing but contempt for its now annual, anti-Linux patent threats. On the other hand, I don’t see Mono, the open-source implementation of Microsoft’s .NET programming environment and its related languages, as being an open-source “infection;” or particularly “dangerous,” much less that “MONO people have poisoned your minds and infiltrated Ubuntu to get power to enforce their will.”

Get a grip people!

Yes, Mono is based on Microsoft’s .NET. Like it or not, several valuable open-source programs like Tomboy, a well-regarded note-taking program; Moonlight/Moonshine, which enables you to listen and view Windows Media-bound music and videos on Linux; and Banshee, my personal pick for the best Linux music player, are Mono applications.

Would it be better if these applications were written in some more free software ideologically pure language? I doubt it. They were written in Mono, not Python or C++. It’s a pointless question. If you don’t like them, write better ones in another language. It’s the open-source way after all.

Taking a beating with Windows 7 pricing

When you buy a PC what do you think the single most expensive part? Is it the CPU? Nope. The hard drive? No way. It’s long been Windows, and, with the coming of Windows 7 on netbooks and lower-priced PCs, Windows may not only be the priciest part, it may cost you more than everything else in the PC combined. Now, that’s real value for your money!

Windows 7 Starter Edition is expected to cost netbook vendors $50. That’s not much, but it’s a good deal more than the $15, and less, it currently costs them to put Windows XP Home on their machines. Adding insult to injury, Microsoft has decided that Starter Edition can only go on a netbooks with a 10.2-in. Or smaller screen , with no more than 1GB of RAM, a hard disk drive of no more than 250GB or a solid-state drive no bigger than 64GB, and a single-core processor no faster than 2 GHz.

In short, if a netbook manufacturer wants to produce a high-end netbook, Microsoft is forcing them to use Windows 7 Home Premium. And, guess what? According to a report, Mike Abary, a senior VP at Sony’s Vaio PC unit, says that Windows 7 Home Premium will “add $200 to a unit’s cost.” On an advanced netbook, or low-end notebook, that could easily mean that Windows is the most expensive part of the entire package.

So long CompuServe, nice to have known you

If you were lucky enough, as I was, to go to a technically-advanced school or work for a high-technology company in the 70s and 80s, you had Internet access. For most of us though the only way we had to go online was via an online service like CompuServe. Recently, after 30-years of service, CompuServe closed down. I’ll miss it.

I was fortunate to be on the Internet starting in the late 70s, when I was at school, West Virginia University, and later at my jobs at Goddard Space Flight Center. But, when I was at home, I had to use a 300-baud Hayes modem like everyone else in those days to go online. So, I became an early user of online services And, by the early 90s, I was writing a column about them for Computer Shopper, back in the days when that publication was a 1,000+ page giant on magazine stands.

In those days, everything that we now think of as being part of the Web, was only available in far smaller, text-based portions on online services like AOL, BIX, CompuServe, Delphi, GEnie, and Prodigy. Today, only AOL remains in a form that any time-traveling user from 1992 would recognize.

I liked all these services. Well almost all, it was never easy to warm up to Prodigy with its slower than slow speeds even by 1200-baud bound standards and its clunky interface. But, of all them, I liked CompuServe the best.

Long before social networks like Facebook and Twitter enabled us to keep in touch with each other, many of us were being talking with each other all the time on CompuServe’s Forums. To this day, I think CIS’ (CompuServe Information Service) Forums were the best online discussion areas I ever had the pleasure of using.

In no small-part that was because while the online software itself usually worked well, it had an open API (Application Programming Interface) so that you could use off-line readers like TAPCIS and Golden Compass. These made it possible to maximize your online conversations without running up huge telephone and online service connection bills.

One of the invisible changes that the early 90s’ switchover from online services to the Internet brought was the end of hourly connect time charges. If you didn’t watch out, you could easily run up hundreds of dollars in connect charges a month. CompuServe made it possible for savvy users to get the most from the service for the least amount of bucks.

Today, the Internet is much cheaper than the online services ever were. And, you can do things with the Internet, like watch televised baseball; play elaborate games and video-conference, that we never dreamed of in those days. You know, though, both then and now I get more done and more pleasure out of ‘talking’ with people online in e-mail and in online discussion groups.

So, good-bye CompuServe, your day is done, but your core virtue, enabling people to form communities and make and maintain friendships over the miles, remains in a thousand different forms today.

This is 72441,464 signing off for the last time.

Go to Toys ‘R Us for your Linux netbook needs

One of the most annoying things, thanks to Microsoft strong-arming PC manufacturers, is finding a Linux netbook to buy at a store-front retailer. But, it turns out that there’s at least one store that still carries Linux netbooks: Toys R Us.

Why? Well, perhaps Microsoft overlooked it, but small computers, like netbooks, turn out to be ideal for people with small hands-kids. So it turns out that Toys R Us still carries 7″ netbooks.

To be exact, the chain carries the Asus 701SD, in white and black versions, and the Asus 900A. Both run Xandros Linux.

Now, neither of these computers are state of the art. Both computers, for example, uses a 900MHz Celeron processor rather than a 1.4GHz Intel Atom. The 900A, with its 8.9″ screen size, a GB of RAM and a 4GB SSD (Solid State Drive), is clearly the best of the pair. That said, no one will ever mistake either of these as great netbooks.

London Stock Exchange to abandon failed Windows platform

Anyone who was ever fool enough to believe that Microsoft software was good enough to be used for a mission-critical operation had their face slapped this September when the LSE (London Stock Exchange)’s Windows-based TradElect system brought the market to a standstill for almost an entire day. While the LSE denied that the collapse was TradElect’s fault, they also refused to explain what the problem really wa. Sources at the LSE tell me to this day that the problem was with TradElect.

Since then, the CEO that brought TradElect to the LSE, Clara Furse, has left without saying why she was leaving. Sources in the City-London’s equivalent of New York City’s Wall Street–tell me that TradElect’s failure was the final straw for her tenure. The new CEO, Xavier Rolet, is reported to have immediately decided to put an end to TradElect.

TradElect runs on HP ProLiant servers running, in turn, Windows Server 2003. The TradElect software itself is a custom blend of C# and .NET programs, which was created by Microsoft and Accenture, the global consulting firm. On the back-end, it relied on Microsoft SQL Server 2000. Its goal was to maintain sub-ten millisecond response times, real-time system speeds, for stock trades.

It never, ever came close to achieving these performance goals. Worse still, the LSE’s competition, such as its main rival Chi-X with its MarketPrizm trading platform software, was able to deliver that level of performance and in general it was running rings about TradElect. Three guesses what MarketPrizm runs on and the first two don’t count. The answer is Linux.

Ubuntu heads to the clouds

On July 1, Canonical, the company behind Ubuntu in partnership with Eucalyptus Systems, an open-source cloud infrastructure firm, will be launching Ubuntu Enterprise Cloud Services.

According to sources at Canonical, Ubuntu Enterprise Cloud Services "is a set of new professional services to help and support users building ‘private clouds’, that is cloud infrastructures behind a corporate firewall."

This follows up on Canonical’s technical preview of UEC (Ubuntu Enterprise Cloud) in April. an open-source system that enabled organizations to build their own clouds that can work with Amazon EC2. UEC will be incorporated into the Ubuntu Server Edition technology stack.

The idea, as it always is with cloud computing is to save organizations money by optimizing server use, while lowering costs and providing end users with self-service IT. With Ubuntu Enterprise Cloud Services, Canonical will help businesses build private clouds

In a statement, Mark Shuttleworth, Canonical’s CEO said, "Enterprises are realising that building ‘private clouds’ enables them to better manage variable workloads, while reducing the waste of idle servers. Building on an open-source technology also avoids the issue of vendor lock-in. Ubuntu Enterprise Cloud enables businesses to do this–and the addition of these services helps them to do it with confidence."

Simon Wardley, who heads up Canonical’s cloud strategy, said that, "One of Canonical’s objectives is to ensure that companies not only get the best available open source products but also get the best available support from the people closest to the source of the technology." Wardley added, "Ubuntu is the only distribution which provides an open source cloud system that matches market standards. We’re building upon real solutions built with open source technologies and backed up by real services."

Ubuntu Enterprise Cloud Services will enable users to scale up from a five-machine environment all the way to a site license covering all machines, physical and virtual, in a single location. The Enterprise Cloud is built with Ubuntu 9.04 servers.

Support pricing starts at $4,750 and goes up from there based on the usual factors such as the number of servers and support level. To find out more about this new service, you should visit the Canonical Server Cloud page.

Once more Canonical is showing that, while its reputation is based on Ubuntu, the popular end-user desktop Linux distribution, the company has every intention of competiting with Red Hat and Novell for the business server market.
