JSJ 408: Reading Source Code with Carl Mungazi

Carl Mungazi is a frontend developer at Limejump in London. He is a former journalist and switched to programming in 2016. Today the panel is discussing the benefits of reading source code. Carl began reading source code because he came into programming late and from a different field. His first project was with Mithril, and he read the source code and documentation to help him understand it. The panelists discuss how reading the source code has helped them and others to improve their coding. They compare reading and understanding source code to learning a foreign language, and discuss different methods. Carl gives some suggestions for reading source code effectively. He advises people to be patient and step through the code. Accept that you will probably take a wrong path at some point or another, but the more you read, the more you will see patterns in how libraries are structured. He also encourages listeners to approach the authors, as they are often happy to lend a hand. Reading source code is an active approach of stepping through, debugging, putting in break points, checking the stack, and so forth. It’s also important to do outside research. Since he has been reading source code, Carl has come to prefer plain JavaScript and libraries with as little code as possible. The panel discusses the benefits of small, simple libraries. Carl gives examples of techniques that he learned from reading a library source code and how he applied it to his own coding style. Reading source code has made him more careful about mixing logic and UI, and now he separates them. He also is more confident in seeing a problem, going to a preexisting library, and just importing the fix for that problem rather than the whole library. Reading source code is really about understanding the code you use in your project. It may slow you down, but you’ll be thankful in the long term because it will help you solve future bugs more efficiently. Carl talks more about his debugging process. He still relies on a debugger, but reading a library helps you to see patterns and guess the output of a function. These patterns persist in other libraries as well. Once you can guess correctly what will happen, you go back to reading the code and find instances where the output is unexpected, and fix it. Carl’s closing thoughts are that through reading source code, he has learned that although code is used differently in each library, they are all written in the same language, and therefore interrelated. This gave him more confidence in reading code because they’re all fundamentally the same. When a bug is discovered, he encourages listeners to look at the source code before googling a solution.

Iterating on Open Source - JSJ 615

Iterating on Open Source - JSJ 615

Today the panel is discussing iterating on open source projects. Aimee and AJ recall a conversation they had in the past on this subject and AJ talks about some of his experience iterating with open source. AJ believes that we have an obligation to capture the value of what you create so that we can reinvest and create more value, though he admits that making money in open source is a unique challenge because donations only really work if you have a project that gets billions of downloads a month. As your project grows, it has to change in order to survive, and eventually you will need to get financial support from your project. The panel agrees that some of the main issues with iterating in open source are maintaining the code and getting feedback from users, financial backing, and roadmapping and integrations.The panel discusses their methods for getting feedback from their users. This feedback is valuable because it can show you things that you missed. They acknowledge that there can be conflicts of interest between those who only use the project and those who financially support it, and you have to make a choice. Unfortunately, someone is probably going to be inconvenienced no matter what choice you make. When making these decisions, you have to consider who it helps, who it frustrates, and who it may cause problems for. The panelists talk about different ways they’ve handled making these decisions in the past. The JavaScript experts talk about the importance of having data on your user base in order to make good choices for your users. They talk about different methods for notifying your users of upcoming changes and how it will affect compatibility, and some of the challenges with communicating with your users. AJ talks about an iteration he thought was a good idea but that a lot of people hated and how he noticed that the new users liked it but the old users did not. They panel agrees that people in general don’t like change. AJ talks about what he learned from this experience. Another common issue is integrating with other services. Integrating with cloud services, or at least giving people the option to integrate gives you an opportunity to reach more people and maintain the project long term. AJ gives some final thoughts to close the show, namely that most projects never go anywhere, and that’s ok. If you’ve got something that starts going somewhere, think early on about how you can better serve the community and remember that these people are mostly grateful and semi-willing to support you. He believes that if you are helping people create value, you deserve to see the fruits of your labor. He advises listeners to stay true to your open source ideals, think about your users perspective, and that the earlier you can think about this and make these choices, the better it is for your project SponsorsChuck's Resume Template Developer Book Club Become a Top 1% Dev with a Top End Devs MembershipLinksHow-npm-am-iReactVue.jsLet’s EncryptAsync/awaitNodePicksAimee - Debug Like a NinjaSteve - Jack Ryan AJ - Why I, as a black man, attend KKK meetingsCharles - It’s a Wonderful LifeCharles - Mr. Kreuger’s ChristmasSupport this podcast at — https://redcircle.com/javascript-jabber/donationsPrivacy & Opt-Out: https://redcircle.com/privacyBecome a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.
