A major battle has begun for a city in Iraq, and that's where we begin today's show. I'm Carl Azus,
 
- 
thank you for watching. Fallujah is located in central Iraq, along the banks of the Euphrates River.
 
- 
It's been controlled by the ISIS terrorist group since early 2014. In fact, it was the first Iraqi city that ISIS
 
- 
captured as part of its plan to create its own Islamic State in Iraq and Syria. The fight to take Fallujah back
 
- 
involves Iraqi troops, police, and militias and they're supported by US led air strikes. But trapped in the
 
- 
crossfire between these forces and the ISIS fighters who control the city, an estimated 10, 000 civilian families,
 
- 
according to the United Nations. The Iraqi Air Force dropped leaflets on the city, telling residents how
 
- 
they can get out safely. But activists in the area say ISIS is not allowing civilians to go and that some have
 
- 
died trying to leave. Falluja is where dozens of US troops were killed during the Iraq war in 2004.
 
- 
It's a strategic city that's no stranger to terrorist or violence. Falluja has a long history of bloody battles.
 
- 
It's considered A hotbed of Sunni insurgent groups.
 
- 
This was the first city to fall to ISIS months before any other city in Iraq, in January of 2014. Extremist groups
 
- 
like ISIS and Al Qaeda in Iraq before that used Falluja as a symbol of Sunni resistance. Now for the
 
- 
Shias of Iraq, many of them feel that a lot of the terrorist attacks that target them, whether it's ISIS or Al Qaeda
 
- 
in Iraq before that, those attacks, they feel, stem from Falluja, especially with its proximity to Baghdad.
 
- 
So they really have wanted to see ISIS cleared out of that city for a very long time.
 
- 
Now with this new offensive underway right now, it's expected to last a very long time and expected to be
 
- 
bloody if history is anything to go by.
 
- 
Here what remains a major issue is the civilians who may still be trapped inside that city.
 
- 
The head of security for the US Transportation Security Administration has lost his job.
 
- 
A house of representatives committee announced the change earlier this week. It followed a congressional
 
- 
hearing on mismanagement at the TSA. The organization's in charge of screening passengers and
 
- 
cargo at airports across the US. But the Department of Homeland Security which oversees the TSA says,
 
- 
it's had a number of security failures recently and some have swelled long lines at airport checkpoints,
 
- 
causing hundreds of passengers to miss their flights. The TSA says, Kelly Hogan wasn't fired specifically
 
- 
for doing anything wrong, but that the agency wanted a different approach to security leadership.
 
- 
It's saying that a number of management changes are ahead, and that they'll deliver better
 
- 
leadership and screening operations at American airports.

Starting in Brazil on today's call of the roll, the nation has 26 states and in the northeast state of Ceara Hello
 
- 
to all of our viewers at Escola de Ensino Medio Liceu do Crato. San Juan Hills High School is next, from
 
- 
the US state of California. The Stallions are roaming in San Juan Capistrano. And one state over in Arizona,
 
- 
we've got some Wolverines watching today.
 
- 
Mountain Vista Middle School rounds out our roll from San Tan Valley.
 
- 
The Walkman, the floppy disk, the dot matrix printer, and the VHS, the video home system.
 
- 
These are some of the inventions of the 1970s, that have become obsolete with the passage of time,
 
- 
and the progress of technology. But there are some designs of the disco era that we can't imagine
 
- 
living without. Email, the first video game, cell phones, and one thing that doesn't get a lot of credit but has
 
- 
revolutionized shopping, the barcode.
 
- 
On June 26, 1974, a pack of Juicy Fruit gum made history when it was the first item to ever be scanned via
 
- 
a state of the art technology, the bar code. And now, more than 40 years later, 5 billion bar codes
 
- 
are scanned every day across the world.
 
- 
The code itself, you know those black lines of varying width on the label was inspired by mores code.
 
- 
But the holy smokes component of the innovation was how it was scanned, by lasers. Lasers had
 
- 
been the stuff of nerd fantasy until the early 1960's, when the Hughes Aircraft Company unveiled the
 
- 
first one at a press conference. A Los Angeles newspaper reported the story underneath the headline,
 
- 
LA Man DIscovers Science Fiction Death Ray. But the fact of the matter is, no one knew what to do with that
 
- 
new technology until that June morning in 1974 when a pack of Juicy Fruit gum in Ohio changed the world.
 
- 
Today, bar codes are the unsung heroes that make everything from shipping, into boarding an airplane to
 
- 
keeping track of medication possible. But the biggest beneficiary is retail. Think about a grocery store from
 
- 
yesteryear, every individual item had to be marked with a price and the cashier had to manually input it
 
- 
into the register. So thanks to the bar code, you're waiting in the checkout line a whole lot less. And the
 
- 
stores themselves have benefited big time. The bar codes allow them to keep accurate real time inventory.
 
- 
That's a major advance in efficiency. Even in the costs in groceries staff their jobs.
 
- 
For about 20 people who live in a housing project in Richmond, Virginia, Craig Dodson has become a sort
 
- 
of father figure. The 37 year old leads a non profit organization called Richmond Cycling Core. It allows
 
- 
young people who's opportunities are extremely limited and who's schools are some of the lowest
 
- 
performing to join cycling teams and to train to ride. The lessons and the benefits go far beyond the bike trails.
 
- 
All right. Come on back guys. Rows of five.
 
- 
The thing is for you, you got to get in the woods, all right?
 
- 
And then settle into your rhythm, you know what I mean?
 
- 
Stay positive, run, run, there you go that's how it's done.
 
- 
All during the race, we see our kids are going through this rollercoaster of emotion.
 
- 
Come on, Jay. I know you fell dude, but you got this. What a lot of people can't see is that our kids have the
 
- 
equivalent of ten suitcases each of baggage that they are carrying on that bike.
 
- 
The kids live in Richmond Public Housing. It's not just bad because of drugs, violence, guns.
 
- 
Goodbye.
 
- 
You ain't gotta swerve. You gotta tighten up, man. I'm not playing with you right now, man.
 
- 
I'm being serious. You're clowning way too hard. That's why we've been on you so hard.
 
- 
Matt's gonna be here in the morning to pick you up. We're tired of getting messages from everyone
 
- 
that you're ducking school. It's gotta stop or you're gonna fail 9th grade.
 
- 
We gotta get Antonio. Our organization is not about giving kids positive life experiences through bikes.
 
- 
Our job is to get them out of public housing. The bad news is you gotta little suspension.
 
- 
So we can pick him up in the morning this week, put him to work at least.
 
- 
That's what I do here with him.
 
- 
This is a war to me.
 
- 
What time do you wake up?
 
- 
It's me against the circumstances these kids live in. Thought I was gonna let you off the chain, man?
 
- 
You come in and hold them accountable and it shows a level of care that their not use to.
 
- 
He taught me to be your own person. Don't be what you live around. You never give up.
 
- 
I'm so proud of you man.
 
- 
We see the side of these kids that is genius. There are so many things that we wish the world could see.
 
- 
These are kids that have been let down.
 
- 
Guys, we'll pick you up tomorrow, man, at the same time, all right?
 
- 
My promise to them is, I'm not going to leave you. Good job, today. All right, I'll see you Thursday.
 
- 
All right.
 
- 
Those of you who were not Star Wars fans are gonna see this and think, okay, well loud sliding door.
 
- 
Those of you who are Star Wars fans might hear it and think
 
- 
So again, the R2- D2 screaming door.
 
- 
Maybe the laughter is not as infectious as the viral Chewbacca mask video. But it certainly made
 
- 
some folks Chewbac- up to hear it again thinking it was R2- D2 good to Skywalk through just Ob- 1 time.
 
- 
That's it for today's pun solo, it's part of my Jabba and for putting up with them. Yoda the best.
