Cisco has a really good tech support hot line. I put in a TAC request for a pretty simple question about not being able to configure the serial port.
Create Serial Sub Interface Cisco 2811
"Hi. I can't access the serial port, was trying to configure serial 1/0 on my router cisco 2811 but I guess it does not exist?
The cisco online help says to try
Controller t1 0/0/0
Framing esf
Linecode b8zs
Channel-group 0 timeslots 1-24 speed 64
I did show controllers and all kinds of hardware descriptions pop up but not t1 specifically
The router didn't know what to do with the controller command, I checked the hardware but it does not have a serial port. Is that possible?"
I guess I could pause next time, and give the guy a chance to talk or take notes. Anyway I couldn't immediately provide the serial number on the unit cuz I wasn't logged in and I didn't have the service contract searchable right in front of me. So I mention that I will login and write up the TAC online. While clicking online and trying to find the TAC gui, I stumble upon the link for T1 HWIC cards, like the one that is NOT even plugged into to my unit. There is no WAN interface and link connected, the T1 truly does not exist!
I didn't even have a Cisco T1/ E1 WAN Interface Cards
Anywayz I feel rather silly about calling in the first place but now I have confirmed that the show controller command really works! Once again it is the USER error.

CCNA, ICND1 and ICND2 Practice Exams
I found a really good link on the Cisco Learning Network website for practice questions here.
There are questions for the six modules:
Module 1: OSI Layer and IP questions
Module 2: Hardware, bridges, Hubs
Module 3: WLAN
Module 4: IP addressing, IOS Commands, Routing basics
Module 5: WAN, nat
Module 6: cdp, hardware and memory
There are tabs and links to study modules, 15-20 training videos and lab simulations.
At the login page I also found an ad for a new "game". Cisco Aspire CCNA Edition! Practice for your Cisco CCNA exam by solving realistic networking problems. Seriously? That's a game?
The website Cisco Tests dot org also has a timed exam with pretty realistic questions! It's not for the ICND1 and ICND2 but it would cover the similar line of questioning if you just wanted a timed practise exam experience.

Ask Siri to Sing Happy Birthday
At a friend's birthday party dinner this evening in a very fancy Italian restaurant as we all finished dinner and everyone somehow felt it was appropriate to whip out that iPhone and start texting the buddies at the other long end of the table, the guy beside me suggested let's play Ask Siri!
I don't have an iPhone, I don't even own a cell phone really. I'm very curious who is Suri (I didn't even know how to spell it). The "Industry Canada RF Bandwidth Allocation Committee member" rolls her eyes and says, you folks are wasting bandwidth! I suppose this is true, asking age old questions like why did the chicken cross the road, what is the meaning of life, who's your daddy, and How big is the Pacific Ocean? (that's a good one) Siri gives the answers in Liters with extra information about the comparative volume, 51% of the all the earth's oceans. I'm hooked. I ask, What is Pippa Middleton wearing? Siri displays button to perform a website for that. I'm giggling too much at the idea of asking a computer for answers. I get one of the guyz to ask, what are you wearing Siri? But I miss the answer because it's just too funny.
We're at a birthday party so buddy asks, Siri would you sing happy birthday to my friend please?
Siri answers, Daisy, daisy, give me your answer do.
It wasn't quite the answer I was searching for. People keep texting each other or playing Angry Birds, but I desire an explanation! The Cisco guy at the end of the table explains that it is a cultural reference to the IBM computer that became the first computer to sing Daisy Bell.
In the late 1950's a computer sung a song for the first time. Here is a nice clip from YouTube.
Daisy, daisy, give me your answer do.
I'm half crazy all for the love of you.
It won't be a stylish marriage -
I can't afford a carriage,
But you'd look sweet on the seat
Of a bicycle built for two.
This is quite a cute response. I guess it's an AI joke that's preprogrammed in, but it's still very cute. Well here are some other questions to ask Siri though personally I think people should really talk to their friends at a party and not play with their phones too much. Tweet tweet.

Would you like a slice of Raspberry Pi?
10,000 units sold out in minutes, a $35 programmable GNU/ Linux mini computer the size of credit card. I gotta get one of those on the next batch they bake. It was created in Toronto and manufactured in the UK!
It's so sweet that the inventors initially created this device to be accessible in cost and available one per person with the intention that kids could learn programming.
