Technologists Notes

Oops. I really meant Apollo 11 delivered…

But it’s not July 20 anymore, so about Fedora 11:

• Overall, no big problems
• Fedora Project slipped their final release schedule a couple of weeks, so I didn’t get started trying Fedora 11 until mid-June.
• VMware Server 1.0.x still doesn’t work with the 2.6.29 kernel(s) in Fedora 11. It appears that a one line kernel change is needed (assuming VMware doesn’t fix directly). However, I’ve never built a linux kernel before, and my first attempts have failed.
• The nastiest surprise, for me, was confusion about BIND. I’m used to Fedora putting BIND in a chroot’d jail. Fedora 11 seems to eschew actually doing this, but provides the /var/named/chroot directory hierarchy as if the jail still exists. I don’t find anything in the release notes about any of the BIND changes, and the additional DNSSEC  support in BIND 9.6 threw me off temporatily, since I don’t know much about DNSSEC. It took me a couple of hours to sort everything out, and my current solution is a bit clumsy, but seems to work.

There are other awkward aspects, such as the need for a /boot ext3 partition when trying to use ext4 for the rest of the filesystems, but these are adequately documented in the release notes, so not big problems for me.

I put Fedora 11 on my primary mail/web/DNS server yesterday, and all seems OK so far. (This post is stored on that server.) But the machine that depends on VMware Server is still running Fedora 10.

Red Arco Iris (en Inglés, Rainbow Network) is coming of age and has much to celebrate. From Keith and Karen Jaspers’ vision 15 years ago to today, much has been accomplished.

[en Inglés, Rainbow Network – network of networks]

I spent Friday morning with the managers of the seven Red Arco Iris project regions (“networks”) and other Nicaraguan staff, working towards la red de redes (the network of networks). I believe, and I think the staff believes, that improved use of email, use of Internet shared storage (SkyDrive) and Skype calling will facilitate better communication and more efficient use of time and other resources.

One of the surprises of that session was eagerness to try Linux. I’m encouraging exploration using Ubuntu “live” CDs.

Today was another Capitol 10K. Not a lot different from last year, about 15KM from parking to getting back in the car, a little under 3 hours total this year, about 103.5 minutes on the race clocks, so about 100 minutes, just over 16 minutes/mile, after subtracting for pit stops. (My mental model was to stay with the peloton which maybe I did.)

This year’s cell phone photos are below.

a.k.a. (Google) Docs and other files live in the Sky(Drive)

a.k.a. “This looks great! But how do I use it?” (silence)

Back in the 90s, Larry Ellison and others were positing the feasibility of the “Internet Computer” a.k.a. “Network Computer”, based on “thin client” hardware and ubiquitous network access to servers and services. Though impractical then, computing along those lines is (becoming) practical today.

For those with sufficient  motivation, Google Documents (a.k.a. “Docs”) and (Microsoft) SkyDrive provide enticing capabilities.
