Choose to Return Something Useful
Today, I was working on a method to set a directory for an export. def set_export_dir(dir) @dir = dir FileUtils.mkdir_p(@dir) unless File.directory?(@dir) end My task was to document the method, and in doing so, I found myself trying to reason about the method’s return value. It looks like there are two cases to consider – the directory already existed or we need to create it. If the directory…

Football Scoring, Making Change, and Dynamic Programming
I wrote up my solutions to a common dynamic programming question so I don't forget them.
This morning, I saw the following problem: Given various ways to score points, represented by an arbitrary array w, count how many ways you can add up to a score s. For example, in football, you can have a safety (2), field goal(3), a touchdown + field-goal (7), or touchdown + running in (8), and so w = [2, 3, 7, 8]. An example would be to count how many ways there are to add up to a score of 26…

Today I learned how to set up my site to have persitent anonymous access. Basically, users can come to the site and try things out without having to sign in or up. If they try to vote on a poll, the backend will see a Post request come in and check if a user is signed in.
If there's no user signed in, we make a new anonymous account for the person and keep it in the users table for two weeks. As long as the user doesn't reset his/her cookies, everything he or she does on the site will be persisted as normal. If during the two weeks, the user signs up for a full account, all those changes are ported over to her new account.

Today I spent a while learning how to make ordered associations in Rails. There must be a better way to do it, but what I have for now is working.
Max suggested to add an "ord" column to each of the tables that need to hold ordered resources. This wasn't too bad, but getting the insert and delete queries to run without doing some crazy n+1 db accessing turned out to be quite a challenge.

I did some refactoring today. I'm pretty sick; hopefully a good night's sleep will fix that.

Capstone day5
Today I spent all day stuck down a charting rabbit hole. I'm going to stay here all night and hopefully have something half-presentable in time for tomorrow's peer review.
I'm going to block out my time more thoroughly and limit myself to 25 minutes working at a time to make sure I don't fall into any more time-sucks.

Capstone w2
So everything I try to do on my capstone is taking me forever.
When I sit down to work on something, I start musing over the best way to do it, and before long I'm a thousand tabs deep in google, trying to find out how to use some obscure library.
Hopefully today it'll finally click and I'll iterate on things. Building the naive version first and slowly maturing it toward something bullet-proof.

Capstone Day 3
Today I worked on the back-end a bit more and fleshed out the API end-points so that they return a consistent and intuitive result.
Then I started building up the stores that I'd need for the frontend. It's going pretty well, but I'm a bit unsure of the best way to manage hierarchical data. Also, my code base is in desperate need of refactoring.

Today I spent some time fiddling with bootstrap; trying to coerce a responsive a navbar onto my app, but ended up just writing my own. I'll worry about making it responsive later.
I also built a ton of React components to try to build up one of the more complicated wireframes. It was good practice, and I think I managed to make good decisions, on the whole, about what should be a component and what shouldn't.
Structural styling with CSS was a bit of a pain, but I ended up with something that has about the right shape.
It was slow going, though, so I checked in with an instructor, and boy am I glad that I did! It turns out I've slipped into my old habit of deep diving into things, when at this point I need to be racing along the surface.
Once the MVP is in place, I can go ahead and flesh out some details.

Capstone Day 1
Today was a pretty rough day. For whatever reason, despite spending my entire weekend working on it, I didn't produce a good plan for my project, so I spent a lot of today kind of floundering a bit.
Despite that, I did manage to build auth and set up a JSON API. I spent the night here at the office and redid my wireframes and component trees, so hopefully today will go more smoothly.

UI/UX and Me
Today's lecture introduced UI and UX concepts. Most everything seemed like common sense, but it was a good reminder, and it's nice to have names and words for the concepts.
On to capstones!

So many benches!
Friday was an awesome solo day, where we got to work on building an airbnb clone, where one could find benches. It was really interesting pulling in data from SF parks and rec and google maps.
I can't wait to keep working on it on Monday

React Routes!
Today we built a pokedex using a front-end router. I can't wait to put this new skill to use building Benchbnb today!

Flux!
Today we built a keyboard piano using the Flux design pattern.

React Again
Today's lecture helped to clarify some of the trickier concepts in React, and really helped me understand what was going on. As a pair, we built a simple single page app that was served by Rails.
It was pretty gratifying to see all the pieces come together, and I feel pretty good about our progress today.
Tomorrow we build something musical. That should be fun!

React
Today we used React to build some small and simple "widgets". This was a ton of fun, but is still a little bit unfamiliar for me.
The intuitive and understandable syntax makes React a great choice, and the amount of work that is handled automatically for us, is great!
I'm having some trouble with the design decisions. Hopefully that comes with time.

AJAX
Today we worked on some exercises to help familiarize us with AJAX, and how to use asynchronous requests to exchange small chunks of data in a way that doesn't slow down the user experience.
It was really fun to migrate some logic from the back-end forward into the browser, and I'm looking forward to using this technique in the future to give my sites the appearance of lightning speed.
