| Notes apps I have tried | |
| - Evernote | |
| - way too busy | |
| - tags | |
| - skitch garbage | |
| - no nested folders | |
| - limited features unless you pay a subscription | |
| - OneNote | |
| - not really a text editor (weird text box stuff) | |
| - too heavy |

So I had this situation where I needed to delete an object from the database, if it existed. This is what I wrote:
obj = get_object(1)
obj.destroy if obj
And as I wrote this, it seemed a bit awkward to me. We always said Ruby had a really elegant syntax, but I guess I've come to the place where I find it a little grating. The thing about this example is the asymmetry of it. Conceptually I feel like the if check goes with the assignment, but it's separated from it in a strange way.

data Person = Person { name :: String }have
