I recently upgraded the hardware of my old desktop PC, with the aim of providing the house with a new-ish Linux machine for watching movies and using the internet, and a Windows machine for writing music and playing (old) games. My plan was to use two hard disks: one for Linux, another for Windows, and choose which to use at boot time.

Normal procedure is to install Windows first, then install Linux into a spare partition on the same hard drive (Windows tends to overwrite any disk you put it on). But it's easier to get a Linux machine up and running, see what hardware you've got, and get a decent system without needing to go and find loads of old drivers. So I decided to install Linux first. I plugged in a drive for it as the Primary IDE drive, and installed Ubuntu Linux onto it.

Then, I unplugged the Linux drive, plugged the other drive in, and installed Windows 2000 onto the second drive (just to make sure Windows couldn't overwrite Linux). Got that working too.

Then I plugged the Linux drive in, as the first drive on the IDE cable; and the Windows disk as the second.

The trick then is to get grub (the Linux bootloader I'm using) to present you with both disks as options as boot time. There's a sample configuration in /boot/grub/menu.lst, but that didn't work for me: it looked like it was working, then just hung. I tried a couple of things, but nothing which worked.

Finally, I found this blog entry and used the configuration there. The trick is to make Windows think it's installed on the first disk on the IDE cable. I added this to the bottom of menu.lst:

which does the trick! Now I get a working Windows 2000 option in my grub boot menu.

• Second Thoughts: Blue Moon

  “Look out, Lindens, here it comes. One in a blue moon, a virtual world comes along that might really challenge Second Life — and now it’s here, Blue Mars. Sign up for the beta here that is reportedly opening in June — but only if you are a developer who wants a preview of how your content made on professional software like Maya will look in this world. It’s not ready for the proles yet.”

Whenever there is a major evolution in IT technology trends, the industry has a choice: do we go with proprietary data formats, protocols, and programming interfaces, or do we take a more open approach, allowing the provider with the best offering and service to win without locking in customers?

Some vendors seem to strictly favor the former approach, rushing to do things in unique and protected ways, hoping that they get many customers lined up quickly, and then making it very difficult for them to leave. To me this has always been a business strategy that screams “our offerings and prices aren’t good enough to keep customers, so we need to find another way.” It almost seems like a self-esteem problem, though at a corporate level. It’s often masked by clever marketing and subtle twists on more open messages.

So here we are near the beginning of the Cloud Computing Era. The promise of clouds is that they will quickly and economically give you the computing environments you need in scalable, secure, and flexible ways.

Don’t have a data center? No problem, run it in the cloud. Need a thousand extra processors to handle that holiday retail load? No problem, run it in the cloud. Need to allow your employees and supply chain partners to access the information you need to be profitable and grow? No problem, run it in the cloud.

At the beginning of such eras, silos of functionality appear that prevent easy movement between them by customers. Do you remember before the Internet and World Wide Web really took hold in the mid-1990s? We had individual online providers like Prodigy, CompuServe, and AOL to which people could subscribe. You could logon to each, read your email, get information, and interact in a limited way with friends and colleagues. You couldn’t really reach across from one service and do something in another in an interoperable way. Once the web and its open standards came along, there was no need to have such siloed services, and they all evolved into more open models or went out of business.

So it is now with cloud computing. The providers we have now are open or closed to more or lesser extents. Some are embracing open standards and some are trying to become de facto standards. I don’t begrudge anyone business success in this area. I do begrudge any attempt to lock me into a silo that prevents my moving my data and my applications somewhere else.

Moreover, I think very few people and customers will use just one cloud from one provider. We must have open standards around data formats, security, and management so that cloud computing reaches the lofty goals we have for it, rather than have it spiral down into proprietary islands of insecure and difficult to manage offerings.

Let me leave you with six choices that you should consider as you decide how or if you want to start using cloud computing. Once you settle on your chosen alternatives, present them to the cloud providers you think might get your business. If those providers can’t give you what you want or if they come up with all sorts of excuses about why you really should go with their proprietary view of the world, move on. There will be plenty of clouds in the IT sky from which you can choose.

• You want a vendor who goes it alone, inventing proprietary and non-interoperable ways of working with its cloud; or you want a vendor that has a great product and service that is based on open standards and industry collaboration.
• You are comfortable with being locked into a particular provider’s cloud offering for a very long time, perhaps years; or you want the flexibility of keeping your options open and going with a provider that will let you shift to someone else’s offering should you choose.
• You are fine with immature, vendor defined “standards”; or you want your cloud offerings to maximally used tried and tested open standards developed by industry leaders.
• You want the industry to be bogged down in bureaucratic standards creation for years; or you are all for the creation of just the new standards we need, but created and tested in a timely and cooperative manner.
• You think the needs of the cloud providers come first; or you you think your needs as a cloud customer and user should be primary.
• You believe that the more the industry is fractured around many cloud organizations and standards groups, the better it will be for you; or you want cooperation, transparency, and accountability in the way cloud technology is standardized and becomes mainstream.

I've got some speaking engagements coming up, two of them free of charge.

• This Wednesday I'll be at Manchester United FC delivering the opening keynote at the Local Government Open Source Conference.
• Then on April 15 I'll be speaking at CommunityOne North, which is still open for registrations free of charge.
• It is immediately followed by GoOpen 2009, where I have just agreed to deliver a short keynote and to join a panel with Bruce Perens, Maddog and Larry Wall.
• I also just got the acceptance note for a session at CommunityOne West in San Francisco. I've not been asked to speak at JavaOne (must be a conspiracy against... oh, I don't know, who is the conspiracy against these days?)

If you're attending any of these, be sure to come and say hi!

Ok, so I got a little bit carried away with my Twittering last week when I was in California. Actually, I don’t think it was the Twittering, it was the feeding the tweets into Facebook as status updates. The latter are updated fairly infrequently, maybe one or twice a day, while tweets are created as soon as you think of something clever or at least move a couple of inches from your previous position.

My wife told me it was too much, and she told me about people (nameless so far, but I have ways of finding out) who told her it was too much. My daughter told me it was too much. My son asked me is I had leveled my mage in World of Warcraft. He neither Twitters not Facebooks, and that’s just fine.

This angst came about because of a mismatch between the accepted social networking update frequencies of the two services. Since there is no one service that does everything for everybody, it is tempting to link them together so that some updates from one go into the other. That way you don’t have to run around and put the information into all of them. The problem with this particular link-up, as well as using services like FriendFeed, is that while your original text goes into one place and then gets distributed, the comments can appear in one or more places. So while you insert the message once, you have to keep running around seeing if anyone said anything about it on the various sites to which it was delivered.

What to do?

Option 1: Tweet less frequently. I tweet at an irregular pace, and this could work, but it seems counter to the basic idea of Twitter.

Option 2: Cut the link between Twitter and Facebook. That way I won’t annoy my Facebook friends but I still have to update my status there if I care to.

Option 3: Cut off Facebook wall updates to people who complain. Drastic, but doable.

Options 4: Use the Selective Twitter Status application for Facebook. With this, Twitter and Facebook are still connected, but only tweets that end in #fb get copied in as Facebook updates. Thanks to Eric Newcomer for suggesting this to me.

I went with the final choice and so far so good. I’ve sometimes forgotten to add the #fb, but I can get used to it.

The experience has left me somewhat reticent to Twitter much, but I think I can work my way back. Of course, my Facebook friends might never find out. (grin)

I've finally reached home again after two weeks of travel in the US and Europe; here are a few links to celebrate.

• Waiting for the Barbarians by C. P. Cavafy
  "Now what’s going to happen to us without barbarians? / Those people were a kind of solution."
• More Banking Stupidity: Phished by Visa
  I completely agree with Ben here. The schemes both Visa and Mastercard are running are totally ridiculous, exposing their customers to extreme risk of phishing and leaving them with all the blame when it happens. The schemes are the perfect expression of the contempt with which the credit card industry views its victims (AKA customers).
• Did Red Hat lobby for, or against software patents in Europe?
  Against. I was there & saw it.
• PETA Killed 95 Percent of Adoptable Pets in its Care During 2008
  I'm sure PETA will torch the homes of the people who wrote this very carefully so as to avoid harming any pets.
• Security fears spark Linux drive in Iran
  This has actually been going on for ages I believe, but underlines that, for governments, open source is about sovereignty, as the Brazilians have said for years.
• Internet Archive, Sun create 'living history' of Web
  The Archive moves onto - and in to - Sun. It's an asset of enormous value to us all, I am pleased Sun is able to help it.
• 50 million
  That's 50 million downloads of OpeneOffice.org 3 since it launched in October - amazing. The true number is probably double that, since this does not include package downloads within GNU/Linux distributions. Great way to celebrate Document Freedom Day!

That's it - Europe is now messing with the clock too, so the usual northern hemisphere time-zone spacings are back in place and the Twilight Zone is ended. Now we all need a new excuse for missing those telephone conferences.

• Novell releases SUSE Linux Enterprise 11 - Network World

  “The release runs “with near-native performance” on five major hardware platforms (x86-32, x86-64, Itanium, IBM Power and IBM System z), as well as on all major hypervisors (VMware ESX, Microsoft Hyper-V and Xen). And, as service providers and vendors increasingly look to provide services in the cloud, SLE11 is also supported in initiatives like Amazon EC2.”

I’ve previously mentioned that I’ve had some problems recently with the external drives I used for Time Machine on my Mac desktop. The idea with Time Machine is that it efficiently saves snapshots in time of the state of your hard disk, allowing you to go back and retrieve old files. I initially used an Iomega 500Gb external drive and that worked for about a year.

When that failed last month, I bought a 1Tb Western Digital Drive with FireWire support. I never could get the disk to mount via FireWire, though it did via USB. That was frustrating, because I had paid extra for the FireWire support. After a few weeks, that drive failed and will be sent back.

This week I moved on to a LaCie 1Tb drive. It’s  small and very attractive, just a sleek black box sitting under the monitor. It mounted immediately and offered me the chance to either make one partition or two, with the smaller 32Gb partition useful for transferring among other operating systems that might be on the machine. I went for the latter choice since that appeared to give me more options.

I started the initial Time Machine backup and it hit about 12Gb and then stopped. Time for a web search. Turns out that this is a well known problem if the drive is partitioned with an MBR, a Master Boot Record. This was the case because I had chosen the two partition option. I went into Disk Utilities and reformatted the drive to use the GUID partitioning scheme on the whole drive, then went to bed.

In the morning the 120Gb of 1,431,893 files were less than half copied to the external drive. Huh? Back to the web. What was recommended was that not only do you format the drive as above, but fully erase it in Disk Utilities. I did that, reformatted, and started the backup via the menu item I got when I right clicked the Time Machine icon on the Dock.

This was noticeably faster. It’s been about 4 hours now and only 9Gb remains to be backed up. Within the hour the initial image should be in place and the incremental backups can proceed.

Conclusion: Time Machine is very finicky about the state of the external drive it uses. For a Mac, the whole process is much more complicated than it should be.

• Is open source enabling next-gen vendor lock-in? | The Open Road - CNET News

  “SharePoint is quickly becoming Microsoft’s next operating system, as Microsoft CEO Steve Ballmer has confirmed, with customers required to use it in conjunction with Microsoft’s other software. It’s a one-way street into Microsoft, with a proprietary data repository to make it difficult and expensive to get out. Cisco Systems is fighting back, as is IBM, but few have figured out how to distribute as efficiently as Microsoft. Open source may be the only alternative to Microsoft.”

I’m in the midst of four consecutive weeks of business travel. It more or else looked liked this.

Two weeks ago I drove from northwest New York to southern Connecticut for an IBM analyst event. Six hundred miles there, night in one hotel, meetings all the next day, night in a second hotel, analyst event, six hundred miles home, arriving around 11:30 PM.

Last week I was in DC. Less driving, but I flew to National Airport, went to the hotel, had a meeting with a colleague, then dinner with business partners. The next day I took part in a morning discussion about Linux for government and was done by noon. Because I was originally supposed to have meetings that afternoon, my reserved flight home was at 9 PM. However, those were scrapped and I was left trying to understand how to get home earlier. One option was to rent a car and drive. If all went well, it would take about 6 1/2 hours. Another option was to change the flight. US Air wanted over $600 to do that, and that was simply not going to happen, in this or any other economy.

So I went to the airport, prepared to sit it out. When I checked in via the machine, it asked if I wanted to take the earlier flight. I said “yes,” just waiting for it to ask me for my credit card to bill me $50. It didn’t, but rather offered me seat selection. I got the exit row aisle. Plane left on time and I was home around 5 PM. Too easy. I should have known.

This week was a bit more involved. The primary, compelling event causing me to travel was OSBC. I gave the third and final keynote at the conference in San Francisco on Wednesday.  Around that were meetings, face-to-face interviews, two video interviews, one phone interview, schmoozing, business calls, and a little sleep.

The flight there was fine but filled with little annoyances. I gate-checked my bag for the first leg of the trip and it took American over 20 minutes to get the bags to all of us waiting in the boarding gate tunnel. I found a great spot near my next gate that had an outlet for my computer, but the wifi was too weak to be usable. The plane ride itself was fine, though my stomach was a bit upset so I slept a fair amount. We landed on time around 10:30 PM and somehow I was in my hotel room in Union Square by 11. I did some email and got to bed around 11:30, but my body and my brain thought that was 2:30 AM ET.

The flight home on Thursday was not fine. I got to the airport in plenty of time for my 1:30 PM flight to Chicago, but the waiting area was bedlam and the flight was 45 minutes late.

Two words.

Spring Break.

The airline had not assigned me a seat before I got to the airport and this is usually bad news. It frequently means that the flight is overbooked, so while your seat is “guaranteed” it is not so “guaranteed” that they can tell you where it is. I was eventually given a middle seat. When I inquired why I got this when we had booked several weeks before and requested an aisle (because I’m 6′ 4″), I was more or less told that I should sit down, be quiet, and just be glad I had a seat. There were over 40 standbys for the flight and, while I got my seat, very few of the standbys did.

The plane was a 777 so the middle seat I had was in a bank of five seats in row 19. I got into the plane early enough to stow my roller board overhead, and felt I might still have a fighting chance to make my connection. It was supposed to be an hour and twenty minutes connection time but we were already 45 minutes late. Sometimes with a good tailwind and routing you can make up time but, in any case, it was out of my control.

I settled in, the doors closed, we sat there and then there was an announcement “Flight attendants, disarm doors.” That’s what they do before they open them. A late passenger? Nope, a maintenance issue. It didn’t take too long and off we went.

We landed 30 minutes before my connection, I booked it out of the plane, caught the shuttle across the airport, and got there 10 minutes before the flight. It’s not that they wouldn’t let us on the flight, it’s that the flight left early. There were at least six of us that they stranded in Chicago because that was the last flight. I half considered the rental car thing, but decided against it, even though I drive to and from Chicago three or four times a year. I was tired.

To the airline’s credit, they gave each of us rooms at the airport Hilton for the night at their expense. I was booked on the 6:40 AM flight. So I got up at 4:30 AM on Thursday, showered, dressed, walked to the terminal, got through the maze and disorder that was security that morning, and got to my plane. We took off on time, and I got home by 10 AM.

So Thursday was screwed up. I was exhausted and had to cancel my morning calls. I worked all afternoon and today was a very long and extraordinarily varied day filled with many context shifts from call to call. It was interesting, though strange at times.

So now I can rest, at least until Sunday. Then I fly to London, have meetings on Monday afternoon, fly to Zurich on Tuesday morning, train it to Bern, talk at OpenExpo on Wednesday, train it to Stuttgart via Zurich where I have a 12 minute connection time, and spend two days working in southern Germany. A week from tomorrow, Saturday, I fly home.

You know, I really think I jinxed myself by bringing a complete extra change of clothes this week. Maybe the gods of travel decided that meant I really needed to get home a day later. I expect everything next week to go without a hitch.

Famous last words.
