OpenID first impressions

I have been meaning to try OpenID for some time now and I just noticed that they were doing a free TFA (what they call VIP Credentials) thing for mobile devices so I decided to give it a shot.

I picked Verisign’s OpenID offering; in the past I had a certificate (document signing) from Verisign and I liked the whole process so I guess that tipped the scales in Verisign’s favor.

The registration was a piece of cake, downloading the credential generator to my phone and linking it to my account was a breeze. They offer a File Vault (2GB) free with every account (Hey Google, did you hear that?) and I gave that a shot.

I created a second OpenID and linked it to the same mobile credential generator (very cool). Then I figured out what to do if my cell phone (and mobile credential generator were to be lost or misplaced), it was all very easy. Seemed too good to be true!

And, it was.

Facebook allows one to use an external ID for authentication. Go to Account Settings and Linked Accounts and you can setup the linkage. Cool, let’s give that a shot!

Facebook OpenID failure
Facebook OpenID failure

So much for that. I have an OpenID, anyone have a site I could use it on?

Oh yes! I could login to Verisignlabs with my OpenID 🙂


I tried to link my existing “Hacker News” ( account with OpenID and after authenticating with verisign, I got to a page that asked me to enter my HN information which I did.

I ended up with a page: and a single word “Unknown” on the screen.

I’ve got to be doing something wrong. Someone care to tell me how badly messed up I am?

Update (sept 11)

Thanks to help from Gary (who commented on this post), I tried the “linking” on Facebook again and this time it worked a little better.

But, I still have to enter my password when I want to login to facebook. Something is still not working the way it should.

Still the same issue with Hacker News.

What I learnt from the GMAIL outage

We all have heard about it, many of us (most of us) were affected by it, some of us actually saw it. This makes it a fertile subject for conversation; in person and over a cold pint, or online. I have read at least a dozen blog posts that explain why the GMAIL outage underscores the weakness of, and the reason for imminent failure of cloud computing. I have read at least two who explain why this outage proves the point that enterprises must have their own mail servers.  There are graphs showing the number of tweets at various phases of the outage. There are articles about whether GMAIL users can sue Google over this failure.

The best three quotes I have read in the aftermath of the Gmail outage are these:

“So by the end of next May, we should start seeing the first of the Google Outage babies being born.” – Carla Levy, Systems Analyst

“Now I don’t look so silly for never signing up for an e-mail address, do I?” – Eric Newman, Pile-Driver Operator

“Remember the time when 150 million people couldn’t use Gmail for nearly ten years? From 1993–2003? And every year before that? Unimaginable.” – Adam Carmody, Safe Installer

Admittedly, all three came from “The Onion“.

This article is about none of those things. To me, the GMAIL outage could not have come at a better time. I have just finished reconfiguring where my mail goes and how it gets there. The outage gave me a chance to make sure that all the links worked well.

I have a GMAIL account and I have email that comes to other (non-GMAIL) addresses. I use GMAIL as a catcher for the non-GMAIL addresses using the “Imports and Forwarding” capability of GMAIL. That gives me a single web based portal to all of my email. The email is also POP3’ed down to a PC, the one which I am using to write this blog post. I get to read email on my phone (using its POP3 capability) from my GMAIL account. Google is a great backup facility, a nice web interface, and a single place where I can get all of my email. And, if for any reason it were to go kaput, as it did on the 1st, in a pinch, I can get to the stuff in a second or even a third place.

But, more importantly, if GMAIL is unavailable for 100 minutes, who gives a crap. Technology will fail. We try to make it better but it will still fail from time to time. Making a big hoopla about it is just plain dumb. On the other hand, an individual could lose access to his or her GMAIL for a whole bunch of reasons; not just because Google had an outage. Learn to live with it.

So what did I learn from the GMAIL outage? It gave me a good chance to see a bunch of addicts, and how they behave irrationally when they can’t get their “fix”. I’m a borderline addict myself (I do read email on my phone, as though I get things of such profound importance that instant reaction is a matter of life and death). The GMAIL outage showed me what I would become if I did not take some corrective action.

Technology has given us the means to “shrink the planet” and make a tightly interconnected world. With a few keystrokes, I can converse with a person next door, in the next state or half way across the world. Connectivity is making us accessible everywhere; in our homes, workplaces, cars, and now, even in an aircraft. It has given us the ability to inundate ourselves with information, and many of us have been over-indulging (to the point where it has become unhealthy).

Full Corn Moon

Today was the “Full Corn Moon” and I was lucky enough to get a clear night.

Full Corn Moon, September 4, 2009
Full Corn Moon, September 4, 2009

You can see a larger image by clicking on the picture above.

The moon is barely visible in the first image, hidden by the trees. In the second and the third, it makes it out of the trees just as the sun is setting behind me.

And here I was complaining about Verizon Wireless!

I thought poorly of Verizon Wireless service and features (though I’ve been a customer for a while).

That all changed when I read this.

Hey Verizon, where do I sign up for that two year contract? But, could you give me a cellular data plan with more than 5GB per month please …

Till January 1, 2010, Bye-Bye Linux!

Bye-Bye Ubuntu! Back to Windows …

Around the New Year each year, the fact that I am bored silly leads me to do strange things. For the past couple of years, in addition to drinking a lot of Samuel Adams Double Bock or Black Lager, I kick Windows XP, Vista or whatever Redmond has to offer and install Linux on my laptop.

For two years now, Ubuntu has been the linux of choice. New Year 2009 saw me installing 8.10 (Ignorant Ignoramus) and later upgrading to 9.04 (Jibbering Jackass). But, I write this blog post on my Windows XP (Service Pack 3) powered machine.

Why the change, you ask?

This has arguably been the longest stint with Linux. In the past (2007) it didn’t stay on the PC long enough to make it into work after the New Year holiday. In 2008, it lasted two or three weeks. In 2009, it lasted till the middle of August! Clearly, Linux (and Ubuntu has been a great part of this) has come a very long way towards being a mainstream replacement for Windows.

But, my benchmark for ease of use still remains:

  1. Ease of initial installation
    • On Windows, stick a CD in the drive and wait 2 hours
    • On Linux, stick a CD in the drive and wait 20 minutes
    • Click mouse and enter some basic data along the way
  2. Ease of setup, initial software update, adding basic software that is not part of the default distribution
    • On Windows, VMWare (to run linux), Anti-Virus, Adobe things (Acrobat, Flash, …)
    • On Linux, VMWare (to run windows), Adobe things
  3. Ease of installing and configuring required additional “stuff”, additional drivers
    • printers
    • wacom bamboo tablet
    • synchronization with PDA (Windows ActiveSync, Linux <sigh>)
    • On Windows, DELL drivers for chipset, display, sound card, pointer, …
  4. Configuring Display
    • resolution, alignment
  5. Configuring Mouse and Buttons
  6. Making sure that docking station works
    • On Windows, DELL has some software to help with this
    • On Linux, pull your hair out
  7. Setting Power properties for maximum battery life
    • On Windows, what a pain
    • On Linux, CPU Performance Applet
  8. Making sure that I login and can work as a non-dangerous user
    • On Windows, group = Users
    • On Linux, one who can not administer the system, no root privileges
  9. Setup VPN
    • On Windows, CISCO VPN Client most often. Install it and watch your PC demonstrate all the blue pixels on the screen
    • On Linux, go through the gyrations of downloading Cisco VPN client from three places, reading 14 blogs, web pages and how-to’s on getting the right patches, finding the compilers aren’t on your system, finding that ‘patch’ and system headers are not there either. Finally, realizing that you forgot to save the .pcf file before you blew Windows away so calling IT manager on New Year’s day and wishing him Happy New Year, and oh, by the way, could you send me the .pcf file (Thanks Ed).
  10. Setup Email and other Office Applications
    • On Linux, installing a Windows VM with all of the Office suite and Outlook
    • On Windows, installing all of the Office suite and Outlook and getting all the service packs
    • Install subversion (got to have everything under version control). There’s even a cool command line subversion client for Windows (Slik Subversion 1.6.4)
  11. Migrate Mozilla profile to new platform
    • Did you know that you can literally take .mozilla and copy it to someplace in %userprofile% or vice-versa and things just work? Way cool! Try that with Internet Exploder!
  12. Restore SVN dump from old platform

OK, so I liked Linux for the past 8 months. GIMP is wonderful, the Bamboo tablet (almost just works ), system booted really fast, … I can go on and on.

But, some things that really annoyed me with Linux over the past 8 months

  • Printing to the Xerox multi function 7335 printer and being able to do color, double sided, stapling etc., The setup is not for the faint hearted
  • Could I please get the docking station to work?
  • Could you please make the new Mozilla part of the updates? If not, I have Firefox and Shrill-kokatoo or whatever the new thing is called. What a load of horse-manure that upgrade turned out to be. On Windows, it was a breeze. Really, open-source-brethren, could you chat amongst yourselves?

But the final straw was that I was visiting a friend in Boston and wanted to whip out a presentation and show him what I’d been up to. External display is not an easy thing to do. First you have to change resolutions, then restart X, then crawl through a minefield, sing the national anthem backwards while holding your nose. Throughout this “setup”, you have to be explaining that it is a Linux thing.

Sorry folks, you aren’t ready for mainstream laptop use, yet. But, you’ve made wonderful improvement since 2007. I can’t wait till December 31, 2009 to try this all over again with Ubuntu 9.10 (Kickass Knickerbockers).

OpenDNS again

More on OpenDNS

I wasn’t about to try diddling the router at 11:30 last night but it seemed like a no-brainer to test out this OpenDNS service.

So, look at the little button below. If it says “You’re using OpenDNS” then clearly someone in your network (your local PC, router, DNS, ISP, …) is using OpenDNS. The “code” for this button is simplicity itself

<a title="Use OpenDNS to make your Internet faster, safer, and smarter." href="">
     <img style="border:0;"
          alt="Use OpenDNS" width="155" height="52" />

So, if was sent to my ISP, it would likely resolve in one way and if it was sent to OpenDNS, it would resolve a different way. That means that the image retrieved would differ based on whether you are using OpenDNS or not.

Use OpenDNS

Step 1: Setup was trivial. I logged in to my router and deposited the DNS server addresses and hit “Apply”. The router did its usual thing and voila, I was using OpenDNS.

Step 2: Setup an account on OpenDNS. Easy, provide an email address and add a network. In this case, it correctly detected the public IP address of my router and populated its page. It said it would take 3 minutes to propagate within the OpenDNS network. There’s an email confirmation, you click on a link, you know the drill.

Step 3: Setup stats (default: disabled)

All easy, web page resolution seems to be working OK. Let me go and look at those stats they talk about. (Click on the picture below to see it at full size).

Stats don't seem to quite work!
Stats don't seem to quite work!

August 17th you say? Today is September 1st. I guess tracking 16 billion or so DNS queries for two days in a row is a little too much for their infrastructure. I can suggest a database or two that would not break a sweat with that kind of data inflow rate.

July 30, 2009: OpenDNS announces that for the first time ever, it successfully resolves more than 16 Billion DNS queries for 2 days in a row.


So far, so good. I’ve got to see what this new toy can do 🙂 Let’s see what other damage this thing can cause.

Content Filtering

Nice, they support content filtering as part of the setup. That could be useful. Right now, I reduce annoyances on my browsing experience with a suitably crafted “hosts” file (Windows Users: %SYSTEMROOT%system32driversetchosts).       localhost
[... and so on ...]

I guess I can push this “goodness” over to OpenDNS and reduce the pop-up crap that everyone will get at home. (click on image for a higher resolution version of the screen shot)

Multiple Networks!

Very cool! I can setup multiple networks as part of a single user profile. So, my phone and my home router could both end up being protected by my OpenDNS profile.

I wonder how that would work when I’m in a location that hands out a non-routable DHCP address; such as at a workplace. I guess the first person to register the public IP of the workplace will see traffic for everyone in the workplace with a per-PC OpenDNS setting that shares the same public IP address? Unclear, that may be awkward.

Enabling OpenDNS on a Per-PC basis.

In last nights post, I had questioned the rationale of enabling OpenDNS on a per-PC basis. I guess there is some value to this because OpenDNS provides me a way to influence the name resolution process. And, if I were to push content filtering onto OpenDNS, then I would like to get the same content filtering when I was not at home; e.g. at work, at Starbucks, …

I’m sure that over-anxious-parents-who-knew-a-thing-or-two-about-PC’s could load the “Dynamic IP” updater thing on a PC and change the DNS entries to point to OpenDNS before junior went away to college 🙂

So, I guess that per-PC OpenDNS settings may make some sense; it would be nice to have an easy way to enable this when required. I guess that is a fun project to work on one of these days when I’m at Starbucks.

Jeremiah says, “I do it on a per computer basis because I occasionally need to disable it. (Mac OS X makes this super quick with Locations)”. Jeremiah, please do tell why you occasionally need to disable it. Does something fail?

Other uses of OpenDNS

kuzux writes in response to my previous post that OpenDNS can be used to get around restrictive ISP’s. That is interesting because the ISP’s that have put these restrictions in place are likely only blocking name resolution and not connection and traffic. Further, the ISP’s could just as well find the IP addresses of the sites like OpenDNS and put a damper on the festivities. And, one does not have to look far to get the IP addresses of the OpenDNS servers 🙂

Two thoughts come to mind. First, if the authorities (in Turkey as Kuzux said) put the screws on OpenDNS, would they pour out the DNS lookup logs for specific IP addresses that they cared about (both source and destination). Second, a hypothetical country with huge manufacturing operations, a less stellar human rights record, and a huge number of take-out restaurants all over the US (that shall remain nameless), could take a dim view of a foreigner who had OpenDNS on his/her laptop and was able to access “blocked” content.

Other comments

Janitha Karunaratne writes in response to my previous post that, “Lot of times if it’s a locked down limited network, they will intercept all DNS traffic, so using OpenDNS won’t help (their own default DNS server will reply no matter which DNS server you try to reach)”. I guess I don’t understand how that could be. When a machine attempts a DNS lookup, it addresses the packet specifically to the DNS server that it is targeting. Are you suggesting that these “locked down limited networks” will intercept that packet, redirect it to the in-house DNS server and have it respond?

David Ulevitch (aka Founder and CTO of OpenDNS) writes, “Yeah, there are all kinds of reasons people use our service. Speed, safety, security, reliability… I do tests when I travel, and have even done it with GoGo on a VA flight and we consistently outperform”. Mr. Ulevitch, your product is wonderful and easy to use. Very cool. But, I wonder about this performance claim. When I am traveling, potentially sitting in an airport lounge, a hotel room, a coffee shop or in a train using GPRS based internet service with unknown bandwidth, is the DNS lookup a significant part of the response time to a page refresh, mail message download, (insert activity of your choice)?

My Point of View

It seems to work, it can’t hurt to use it at home (if my ISP has a problem with it, they can block traffic to the IP address). It doesn’t seem to be appreciably faster or slower than my ISP’s DNS. I’ll give it a shot for a while and see what the statistics say (when they get around to updating them).

OpenDNS is certainly an easy to use, non-disruptive service and is worth giving a shot. If you use the free version of OpenDNS (ie don’t create an account, just point to their name servers), there is little possible downside; if you get on a Virgin Atlantic flight, you may need to disable it. But, if you use the registered site, just remember that OpenDNS is collecting a treasure trove of information about where you go, what you do, and they have your email address, IP address (hence a pretty good idea of where you live). They already target advertising to you on the default landing page for bad lookups. I’m not suggesting that you will get spammed up the wazoo but just bear in mind that you have yet another place where a wealth of information about you is getting quietly stored away for later use.

But, it is a cool idea. Give it a shot.
