Projects i've worked on, articles i've written, and tutorials i've recorded
I started this website to share my thoughts about the programming world, as it relates to me. Here i’ll be sharing challenges i’ve faced, the break throughs i’ve made and the experiences had with other programmers. This website aims to chronicle the challenges of a self-taught programmer.
Week 5 takes a sharp turn, sending us straight into web development. It’s a welcome break from programming in C. Fortunately for me I have had prior experience in full stack web development, after taking a few classes over at teamtreehouse. I think that is probably why the open source degree program i’m taking suggests …
Speller problem set explained I’m going to do my best to explain the solution in small, manageable steps so you can follow along and not go through the pain and suffering I did! Maybe running a gauntlet is harsh, but some days were brutal, and at one point I even deleted tons of code after …
Note: I’ve added a lot of code examples in this article towards the end that deal with the resize less comfortable problem that I found difficult to understand. Use a C repl online to copy and paste the github gists (code examples) i’ve included and by understanding how they work you’ll be one step closer to making …
Any Questions? I’m going to be working on my blog posts while doing the walkthroughs next time around. It’s hard to remember what exactly stumped me and how I got around it otherwise. Here are my solutions for the Week 2 walkthroughs. This project was difficult and frustrating for me. I found using the CS50 …
My Advice These next 3 shorts, binary search, recursion, and merge sort were very frustrating at first. Don’t get discouraged. Take lots of breaks, and use the repl.it website so you can write code and see the results quickly. My goal was to write each of these without looking at any reference material, and it …
Computational Complexity How quickly computers run tasks depends on two factors, generally: Physical Resources Source code optimization Let’s take a $5,000 computer, and imagine we run a simple “hello world!” program. An expensive computer can handle it, but so can a cheaper $200 laptop. Run that same program inside a while loop with a condition …
Introduction When a program runs, values are created, modified and destroyed in some cases. Our system needs a medium that can both hold the data and access the data very quickly while the program is running. Another important part of our system is responsible for how fast our programs can run. Because there are many …
Caesar The Caesar cipher is just n steps away from the letter you are given. If the cipher key is 1, and I give you “GH,” then you would move one step to the right of the alphabet for each letter giving you the decoded message “HI.” The cipher key is the same for every letter given. …
Moving things around I decided I wanted to continue blogging even though i’ve spent a lot of time training for the triathlon in May. Here is what my calendar looks like these days: I recently moved some things around to attend two meetups this week. Meetup is a website where you can find events happening in your …
Debugging This short explains several ways of debugging code in the CS50 IDE. First there is the help50 command. below, I’ve written some code that has a compilation bug. This is the output when we run the make command without help50: Using the help50 command: Now we see a human readable message. On line 10 it …
