Off-topic, On-TARDIS

I spent 4 days and change last weekend pretty much out of technological contact with the world.

By this I don’t mean that I limited myself to a single ADSL connection and a dual core laptop. I actually spent most of the weekend limited to Tweetdeck and Foursquare on my cell phone, and I only had connectivity about half of that time.

I was off in the bowels of the LAX Airport Marriott hotel for Gallifrey One, the longest running Doctor Who convention in North America. This 22nd annual event was my third, and before it ended I was signed up for next year already.

I’ve spent much of the past year introducing my companion to Doctor Who and Torchwood, and she came along with me. She was pretty okay with the lack of connectivity.

You’re Out Of Touch…

But I’m a bit baffled that you could have convention facilities that don’t have cell reception or wireless connectivity. Admittedly putting 2200 people into a single floor with laptops and phones and such can be a daunting challenge, but I’m pretty sure we were not the first convention to fill up the Marriott’s lower level.

I did not get around to trying my Clear 4G USB adapter–I have not yet activated it, but if you have an adapter, you can try out your connectivity by downloading their driver software over the 4G connection–but I heard that things were as suboptimal for AT&T and T-Mobile as they were for my Verizon DROID X.

But that’s my grumbling about connectivity. Those of you who watched my twitter feed at @gallifreyan may have seen a reasonable amount of traffic. So I got something.

Doctor Who?

If you haven’t come across Doctor Who lately, well, there’s no excuse. It’s the longest running science fiction tv series in history, coming up on 50 years of existence and 33 seasons of programmes. (It’s British, so I felt the need to spell that word that way.)

Netflix has the new generation (2005-2010) as delivered by Russell T Davies and Steven Moffat, as well as much of the classic series. Amazon’s new Amazon Prime feature, instant video streaming, features loads of the series as well. You can also buy the downloads on iTunes, or pick up spinny glass versions anywhere DVDs are sold.

The sixth series, featuring the return of Matt Smith as the 11th Doctor and Karen Gillan as Amy Pond, is coming sometime in the next two months. No firm dates yet, unfortunately, but the new series should be coming in late March to late April.

I’ve been a fan since 1983 or so, so I have a bit of a lead on most of my readers. But you can get a fair start at the beginning of “Series 1” with Christopher Eccleston, “Series 2” with David Tennant, or “Series 5” with Matt Smith. Your experience will be enriched the further back you go, but these are all sane starting points, and you won’t miss out on too much by not having watched the black and white episodes.

And I’ll be braving my first visit to a Doctor Who fan group this weekend; the San Jose organization “Legion of Rassilon” has been bringing fans together since the very early 80s and I’m looking forward to my late start in the in-person fan community.

Anyway, I should have something more technical for my readers in the near future. Stay tuned, and have a jelly baby for me.

Cheap Gigabit Ethernet Switch – Woohoo

I picked up an insanely cheap Gigabit Ethernet switch this weekend on a junkshop run with a new coworker and an old friend.

It’s a 3com 3C16486 Baseline Switch 2848-SFP Plus that features 48 1000Base-TX ports, four of which are split-personality with SFP module bays alongside the TX ports. It’s web-manageable, for some value of web-manageable, has cable diagnostics built in, and I bought it for far less than I spend on retail brewed coffee in the average month (somewhere between the cost of a Linksys 5 port and Linksys 8 port gigabit switch).

Yes, it’s discontinued, but so are most of my home computing items. I probably have a 3 foot stack of black-and-blue Linksys gear, some pre-Cisco and some post-Cisco. I just figured if I ever get around to building my home lab up, a switch that can do link aggregation and snmp would be good. And it will probably go in an enclosed rack anyway, maybe even in the patio closet.

Anyway, first thing I do when I get a piece of gear, after inspecting and resetting any configuration, is to find the latest firmware and flash it. This wasn’t the easiest thing to do; I found some update pages that offered me the Discovery utility and the firmware update if I just linked a support contract to my 3com web account.

Some creative googling found earlier links on 3com’s site, pointing toward their FTP site which had outdated versions that were older than my current version. A bit of further searching found an earlier version of the Updates page which gave me a newer version of the firmware, v1.0.3.3.

Turns out the default/post-reset IP address is on a sticker on the switch, according to the Users Guide, so I didn’t need the Discovery utility, which I had found at a similar link. Just as good, as it did not seem to run on Windows 7 even in “Windows 95” compatibility mode.

So I plugged my Windows 7 laptop (32-bit) into the switch, used a 169.254 address to hit the switch, and tried uploading the new firmware. It kept losing connectivity to the switch, then the http session would fail as if it timed out, then pings would come back and I could get back to the failsafe screen and start over.

I found a German page that told me to use IE. I had thought of that, but I rebooted Windows 7 (with new AV, which I had tried turning off along with the firewall), loaded IE, and got the same behavior.

I can’t really say why, but going back to Windows XP on an older laptop and running Internet Explorer to do the upload made the upgrade work. I’m now up and running with a nice 48-port switch that is overkill for anything I might want to do, and I have a good reason to keep that XP machine handy in the future.

Next step is to see if I can find another one or two of them for the same price… although I should also mess with the Cisco 1711 I got with analog module… why did I do that? Oh yeah, it might take the DSL module.

 

Afterthought (2/15/11): I went back and grabbed the other two that were available. One came with a 3com-blessed SX SFP module. Not too bad.

Some thoughts from Tech Field Day 5, Day 1.

I’ve been watching some of much of TFD5 on the streaming site, taking advantage of the “home game” via Twitter. I was invited to join the last bit of today’s session in person, and had a good time meeting the delegates and a couple of the vendor reps as well as seeing Xangati. But I’m an indirect participant so far. Thanks to Steve Foskett for inviting me and everyone for making me feel welcome. Well, maybe not everyone.

First, to go beyond the point Networking Nerd made, “Streaming video is frowned upon by almost every cell phone provider.” It’s an imprecise science on the move, in any setting… apparently one host’s network security policy was also a hindrance, and it probably didn’t help that I had the “BBC Closing Sites Archive” torrent running full-stream on my part at home. But hopefully future hosts will be better prepared. The Computer History Museum’s wifi was apparently providing close to 10 megabits each way, so we know it can be done.

Second, it may make more sense to push a smaller-footprint solution upward than to squeeze an enterprise solution downward. I caught most of the Druva presentation on near-CDP aimed at portable computers. I’m going to try it out myself (I have a dozen portable computers at home, and I can probably borrow a portable Mac other than my Mac Portable (yes, I have one, it’s verra nice)… and then I’ll relay it to my IT team at work. Sure, we have Time Machine for the Macs, but there are a fair number of Windows machines where near-CDP would be a good idea, especially for remote and mobile workers.

Third, being able to play back activity patterns in your virtualization environment looks really cool. Some of you saw a bit of my live tweeting from the Xangati presentation. They’re doing a product that visualizes and “records” what interacts in your virtualization setup, from the VM infrastructure to the network. Having deployed and monitored a six-node XenServer Enterprise cluster, I can say it’s very painful to keep an proactive eye, or even a quickly reactive one, on even a simple environment where VMs and storage may interact with each other and run over each other. I’ll likely be putting their free ESX tool into my personal lab at work and seeing how it works. My IT team is working on managing a small pile of ESXi boxes as well (my pile of ESXi boxes are nested virtually inside a physical ESXi box).

Fourth, it’s interesting to contemplate a solution independently of its pricing, but when a site isn’t very forthcoming about product pricing, I find myself less likely to seriously consider it. Sure, make me get in touch to get discounts, promos, free lunch, polo shirts with built in Beats By Dre ear buds, and so forth… but I have to feel that I can get away with buying something before I’ll dive into it in my copious investigation time. Sort of a phase 1 sanity check against possible benefits and returns. One of the vendors didn’t have obvious pricing, just an obvious free eval. Google helped me find their pricing page though, and it wasn’t that bad.

Fifth, did Curtis Preston actually expresslonging for the growth of the “private cloud” ? I guess not.

Sixth, I probably have a mild feel for how Mr Backup feels about that phrase, from how I felt when someone compared a semi-realtime backup product to Dropbox (which is a great product, and a company with a cool office in San Francisco). SugarSync has more pertinent features, like configurable backup directories (I back up my Dropbox to SugarSync just to be redundant), but it’s still a directory backup tool, not a recoverable system backup.

Seventh, from the “hallway track” and Virtual Bill, I learned there’s a free open-source virtual switch for Xen (XenSource and XenServer, it seems) and KVM: openvswitch. I knew about the free Arista Networks vEOS virtual switch for VMware, but it’s nice to see something for the Xen side of the house. I’ll admit I still don’t do deep enough virtualization work to need these, but it should happen sometime this year. And while vEOS doesn’t have the features that drew me to Arista (buffered Gigabit Ethernet and top-of-rack 10GBase-T), it seems well worth a look.

Eighth, in case you haven’t looked at VMware Player recently, it’s worth a peek/re-peek. I used a personal VMware product back in the Workstation 2.x days (when I got a hobbyist license for $99 per platform), and when Player came out, it was somewhat crippled. In particular, it was a pain to make new VMs. You had to get a downloaded program or find the website that created vmx containers, or start from a Virtual Appliance and try to work your way from there. Now, not only can you readily prepare a VM from scratch, you can also use Unity, to display individual app windows from your guest OS in the host OS. Pics or it didn’t happen? OK. This means with the right prep, you can run your favorite Internet Explorer on your gentoo or ubuntu laptop. Or you could do something more sane, like run a browser appliance for security/compartmentalization, run an older version of Windows or Linux or Solaris or FreeBSD, or even just keep Xeyes up on your Windows box to confuse your friends and distract your enemies.

That’s all I can think of at the moment, and it’s actually a lot considering most of this was on the side monitor while I was doing somewhat real work in the foreground. I don’t know how much of tomorrow’s events I will watch in realtime, as we have a new hire to welcome with an expensive lunch.

As an aside:

You can find me on Twitter as @gallifreyan … be warned that another side of my geekiness, the Gallifreyan side, will be approaching its annual apex as Gallifrey One approaches next Thursday through Sunday in Los Angeles. #gally is the hash tag to watch for or avoid as the case may be. And in case you’re wondering, my Doctor was Rowan Atkinson.

Resource sharing, time sharing, 2011

So I think it’s time to start putting some thoughts down and engage my colleagues in a more-than-140-character manner.

My first serious programming was on a PDP-11/44 at college in Indiana… RSTS/E (the follow-on to RSTS11) was the operating system, standing for resource sharing/time sharing. I was trying to think of a blog name, and that really clicked for what I’m thinking about at a very high level.

I doubt that I will pull a Sinclair and change the name every year, but we’ll start from ’11 and go from there.

Say hi if you’re here, and if you’d like a linkback.
