Continuous Updating
How do you keep track of your LIBRARIES?
How many DEPENDENCIES do you have in your project?
Which LICENSES are your dependencies using?
You don’t know?

15 years ago we used to work with the WATERFALL MODEL Requirements Analysis Design Coding Testing Accepting
But today we are AGILE!
Everything the Waterfall Model used to execute in one year ... ... we nowadays execute in 2 weeks!
The way we develop software today totally changed!
Being AGILE got us CONTINUOUS Refactoring CONTINUOUS Testing CONTINUOUS Integration CONTINUOUS Delivery
But what about CONTINUOUS Updating ?
How do you update your LIBRARIES ?
You don’t ?
Because you never touch a running system, right ?
So you wanna work with COBOL ? Right? Enjoy!
“If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward. ” Martin Luther King Jr.
Core committers don’t release new versions just for fun!
They always have good reasons • Bug Fixes • Security Fixes • Speed & Memory optimization • New Features
How do you ensure that new versions don’t break the system?
Semantic Versioning Migration Paths Continuous Testing
http://semver.org/
MAJOR.MINOR.PATCH 1.MAJOR version when you make incompatible API changes 2.MINOR version when you add functionality in a backwards-compatible manner 3.PATCH version when you make backwards-compatible bug fixes.
Always follow the MIGRATION PATH!
Many small steps are better than one big step You can do SMALL MIGRATIONS on the fly. BIG MIGRATIONS are risky and expensive. If you miss versions, you miss migration paths, too. And that leads to TROUBLE!
Always run your TESTS against new versions
Another reason for being current
Do you really believe those young talents wanna work with COBOL? Or other OLD SHIT?
Tracking versions is a pain!
SOFTWARE LIBRARIES are NOT like iPhone Apps!
100 libraries per project in avg. After 2 weeks the first libraries are OUT-DATED !
Developers are missing critical BUB FIXES and important UPDATES !
Manually checking for updates is no fun! It cost TIME & MONEY ! NOBODY WANTS TO DO IT!
So, how do you wanna solve this PROBLEM ?
You have to AUTOMATE !
You need a TOOL for that!
