A solution to software maintenance from long ago?

Communications of the ACM: You Don’t Know Jack About Software Maintenance:

Software maintenance is not like hardware maintenance, which is the return of the item to its original state. Software maintenance involves moving an item away from its original state. It encompasses all activities associated with the process of changing software. That includes everything associated with “bug fixes,” functional and performance enhancements, providing backward compatibility, updating its algorithm, covering up hardware errors, creating user-interface access methods, and other cosmetic changes.

In software, adding a six-lane automobile expressway to a railroad bridge is considered maintenance–and it would be particularly valuable if you could do it without stopping the train traffic.

A Thank You to Sesame Street

The Muppet Newsflash: Sesame Street Celebrates 40th Anniversary with Two New History Books

Old clips of Elmo with Kermit on YouTube helped me expose Emma to the Muppets a few years ago. Now Muppets are part of the Sesame Street universe for her, as it was me and Richelle when we were growing up. Here are two great ones:

I could post a million videos but you’re better off just visiting the Sesame Street channel on YouTube

And as Emma knows, Kermit’s my personal favorite. Its great that we can watch the old Muppet movies with her and she loves them is so much fun.

YouTube: Muppet Movie – The Rainbow Connection:

Lately on YouTube, the Muppets Studio has been posting new videos, this one is genius!

YouTube: The Muppets: Bohemian Rhapsody:

And one last one, not to show to kids, but too funny not share:

YouTube: The Song of the Count – Lemon Demon Version:

I wonder, now that the Muppets and Sesame Street are owned and operated so separately, will there ever be a moment in any future movie like the wedding chapel in Muppets Take Manhattan? When Emma saw Big Bird and crew in the pews, she yelled with surprise and joy.

I think we used Sesame Street as a guide for what constituted ‘good’ children’s television for us. The Backyardigans, Jack’s Big Music Show, The Wonder Pets, Blue’s Clues (did you know Blue’s Clues was created by former Sesame Street writers?), Dora and Diego, all are in its spirit. No Baby Einstein, and nothing that had more quick shot cuts than Sesame Street for example, Yo Gaba Gaba. Good songwriting, flow, encouragement of imagination and *thinking*. That’s what we were looking for in children’s television. And I think we can say thanks to Sesame Street for that.
