Skyscanner Journey - From code jungle to state of the art

Very interesting use case.

Very interesting and digging into the real "how to".

I understood the talk as "We had this" and "We now have this and is cool". I was expecting a deeper explanation about how you change from a legacy system to a new modern system, which difficulties you find and how you get over them.

A mildly interesting study case, but the speaker need a little bit more of passion and dynamism. Nonetheless, some good lessons were extracted.

Good explanation of a real case

Interesting talk about a real case scenario with a lot of description and a very little intention. Maybe the speaker should have wondered why this is an example to talk about more than just plain explaining it.

Interesting talk

We're always asking for real world scenarios in talks, and we really got that with this one. I expected more detail in the move from old code to the new one.

Good presentation but too litle detail I expected more explainations.

First of all I would like to thank you for taking the time and giving me your feedback, be it both positive or negative. I'm actually focusing more on the negative comments (3 stars or less) because that's where I can actually improve for the future.

I understand that some members of the audience expected more details on the steps we took to migrate the codebase and now, in hindsight, I think I should have focused more on that part. I tried to pack 6 months of work in around 40 minutes of presentation time and it seems some important items were left out.

A short overview on how we went about it: we identified the only part that could be salvaged, our business logic and we moved that into the BLS connector repository, which was unit tested and pulled in both the Yii and Silex applications. This way, changes to the business logic done for the current application (Yii) will be preserved in the new one and developed according to the new quality standards. The ZF1 app was too broken to actually do something for it. Unfortunately there was nothing else we could salvage so we began to hack and slash the code. That's when we started looking for the new framework and going forward. I think a couple of slides on this decision would have made a world of difference.

If you have more questions, please get in touch over email ([email protected] or [email protected]).

Thank you again for your feedback and have a nice day.

The talk was ok, in content and delivery. The interesting part is about when you know of a company like skyscanner and someone offers to tell you about how it runs, what technologies they use, etc; but maybe as a programmer I would have liked to see something more programming/refactoring related
