Pinterest is an excellent example of how the 3 things (display, storage, and math) come together to create a web app. I love Pinterest. Scrolling through photo after photo. It’s a great way to relax. So that’s the easy part. You can see the display right there. But how are you able to see the…
So how do computers display, manage data, and do math? Glad you asked. Display HTML, CSS, and JavaScript are the tools developers use to create what you see when you look at a computer screen. Every browser can compile these three languages to present a web page. Written correctly, HTML can also make the site…
Computers do 3 things. They: Display things Store data and retrieve that stored data Do math That’s pretty much it. Now, yes this is simplified, but hopefully to the point that it is useful. Let me explain… They display things: When we use a computer or a phone we see what the code said to…
The first courses I took at Skillcrush were design courses. And boyee, was I way over my head. I had never used Photoshop or any part of the Adobe suite. I would spend a half-hour just trying to move a box on an artboard! I spent Thanksgiving working through all the Photoshop and Illustrator tutorials…
About a year and a half ago, I decided to learn to code. I started taking coursework through Skillcrush. And it has been awesome. So, now I’ve pretty much finished what I originally set out to do. I’m still finishing the Freelance blueprint (more on that later). I wanted to understand how the internet worked,…
Network error while fetching https://rubygems.org/quick/Marshal.4.8/rack-1.6.0.gemspec.rz (execution expired) I’m working on trying to figure out why this is happening. Still in the Google search stage. But I’m going to restart my computer and see if that automagically fixes anything. Ok, big shocker. Restarting my computer automagically fixed it. I was able to use bundle install (Awesome!)….
What seems to have worked. However, I might instead try using the command line instead. See notes is Path Warning folder .bash_profile function proml { case $TERM in xterm*) TITLEBAR=’\[\033]0;\u@\h:\w\007\]’ ;; *) TITLEBAR=”” ;; esac PS1=”\u: \[\e[32m\]\W\[\e[0m\]\n\[\e[0;31m\]♥ \[\e[0m\]” } proml PATH=”/usr/local/bin:$PATH” # Add RVM to PATH for scripting. Make sure this is the last PATH…
When you don’t know what you’re doing and so you just follow directions…things can go sideways quickly. I think I followed directions but it really doesn’t look right. Also, I believe I should have used a command line uh, line to correct the path issue. rvm & all. When I have this figured out, I’ll…
Ok, so the last 3 days I’ve been working on making an app that creates a database. To do this, I’m using ActiveRecord, PostgreSQL, and Sinatra (maybe). Boy has it been a whirlwind! I learned that psql –help can get you help of PostgreSQL. and that psql is a shell like bash is. psql -l gives you…
