Conor Grennan was unwilling to be a volunteer . The 29-year-old American was not sure if he had the skills or a strong feeling for it. However, he went to work at an orphanage in Nepal. His first thought was to make people impressed. "I thought that if I volunteered just once. I could retell the story over and over," Grennan said in a Huffington Post article. However, his three-month stay it the orphanage turned into in unusual experience. It was 2004 and Grennan had given up his job to begin a year-long around-the-world trip, His first three months were spent in Nepal. When he arrived in the village, he knew nothing about the children or the local culture. When he opened the gate of the Little Princes Children's Home, he was faced by the excited children. The young American ended up caring for 18 children. He later discovered that they were trafficked children. So he walked through the mountains with great difficulty to find the kids' families, "I started walking with photos of the kids." he told the Reuters reporter. "I would show up in villages and show photographs around. I went with 24 photos, and I found 24 families." At the same time, he put his heart into Nepalese culture. Grennan said, "Volunteering is the single best way to see how the rest of the world lives." He also encouraged others to do what he had done. He believes that volunteering needs only making decisions to show up. Grennan's fight against child-trafficking has changed him. His book, Little Prince, came out last week.

Problem: MaxiCode is a public domain, machine-readable symbol system originally created and used by United Parcel Service. Suitable for tracking and managing the shipment of packages, it resembles a barcode, but uses dots arranged in a hexagonal grid instead of bars. MaxiCode has been standardised under ISO/IEC 16023.

A MaxiCode symbol (internally called "Bird's Eye", "Target", "dense code", or "UPS code") appears as a 1inch square, with a bullseye in the middle, surrounded by a pattern of hexagonal dots. It can store about 93 characters of information, and up to 8 MaxiCode symbols can be chained together to convey more data. The centered symmetrical bullseye is useful in automatic symbol location regardless of orientation, and it allows MaxiCode symbols to be scanned even on a package traveling rapidly.

MaxiCode symbology was released by UPS in 1992.

MaxiCode symbols using modes 2 and 3 include a "Structured Carrier Message" containing key information about a package. This information is protected with a strong Reed-Solomon error correction code, allowing it to be read even if a portion of the symbol is damaged. These fields include:

The structured portion of the message is stored in the inner area of the symbol, near the bull's-eye pattern. (In modes that do not include a structured portion, the inner area simply stores the beginning of the message.)

question: (CNN) -- All big ideas start small, and Calle 13 -- a wildly popular alternative urban band from Puerto Rico -- is no exception.

Its members, Rene Perez, who goes by "Residente," and Eduardo Cabra, "Visitante," are stepbrothers. When their parents divorced, Cabra would visit Perez at his father's house on 13th Street, or Calle 13.

He was required to identify himself to enter, as either a resident, "residente" or visitor, "visitante," in Spanish.

The names stuck.

"Later, it took on another meaning, with the question of whether immigrants are residents or visitors," said Perez, who along with Cabra, recently sat down to talk with CNN en Espanol's Claudia Palacios. "But that was how it started."

Neither brother could have imagined then what Calle 13 would become -- one of the most highly praised and talked-about groups to come out of Latin America in years. It has won more than 20 Grammys and moved beyond its reggaeton roots to include instruments and sounds from all over the region, winning critical and popular praise in the process.

Though raunchy, the group's lyrics are often hard-hitting on social issues, and Perez is particularly well-known for being outspoken about poverty, Puerto Rican independence and education.

Asked how he views his career now, Perez said he's matured and made some adjustments so that people can better hear and understand his message.

"I liked to use bad words," said Perez, who raps and writes the group's lyrics. "Because it seemed to me it gave a reality that's missing in music."
