Getting back into coding challenges (to get ready for interview questions)

DAY 408

Met with a programmer friend this week for some advice and a really basic mock interview.

She gave me a couple of problems from CodeEval, and I was definitely feeling pretty rusty on pure logical programming. I’ve spent the last 6 months learning web stuff, which consisted of lots of tools and concepts and libraries, but very few algorithms etc.

Over the past few days, I’ve been working through the easiest of the challenges that have been added to CodeWars since I last used it in December. I’ve completed 70 small tasks, and I’m starting to feel a bit more comfortable again.

I think I’m going to go through CodeEval starting on their easiest exercises, and check them into one big GitHub repo. They only have 240 compared to CodeWars’ 1500 JS challenges, but they seem to be more substantial.

CodeEval just has you work locally and upload your solutions, so this will also be a nice opportunity to switch away from my last remaining online editor (CodeWars). Working with my own editor/workflow will be nice, after spending so much time lately getting used to all those hotkeys etc.

One really nice thing I will miss about CodeWars’ editor is that they have a nice built-in test case functionality. If I’m feeling ambitious, maybe I’ll also learn some Mocha and use this as an opportunity to finally get some real TDD experience.

“Give me six hours to chop down a tree and I will spend the first four sharpening the axe.” - Lincoln

So I went into preparing for App Academy with a lot of plans.

I was going to do all the homework (done).

I was going to do it all again to make sure I really really know it (did some of it).

I was going to do the Hartl tutorial 3 times (did it once).

I was going to read through old App Academy blogs (I read them as they are posted). 

What I have actually done. 

Gone to a lot of meet ups and learned a lot of things

Tried a lot of different sites that teach rails and ruby. 

started to build the Sudoku App. 

Done all the homework at least once. 

Done over 70 CodeEval problems. 

Done project Euler problems. 

Create a Rails TicTacToe App (not great, but functional) 

Done parts of the Blogger tutorial. 

Do I have regrets? 

I actually don't. Yeah I didn't follow the plan. I'm pretty sure that success is not actually related to following the plan success is related to knowing when the plan isn't as good as what you are already doing. I mean I started the AI for the Sudoku in command line just because I thought it would test me on Ruby classes, etc. Of course half way through I realized that maybe it would be interesting to turn it into a Rails App especially because I had done the Hartl tutorial and had no idea how to create a rails App. I began by doing part one of the Blogger tutorial intermixed with building models and controllers for the Sudoku App. I spent about an hour googling for every 30 minutes I was coding, and about 30 minutes recoding for each of those time periods. I learned more doing that than I learned from any of the coding I had been doing reworking tutorials. So I changed the plan I rebuilt the app. I rebuilt it again. And now I have built model, controller, and route tests. I know most of the codes off the top of my head, if not all. Basically now I can build an app with some minimal googling especially on the databases, but not a problem at all. 

Moving into my last days before App Academy we will not be looking to redo things, but to move forward learning new things. Hopefully, the App will be done by the time I start next Monday.
