And so the curtains fall on.
With this last post, I will officially say goodbye to OSD700, a course full of discoveries and learning.
Let's talk about OSD700
I have mentioned several times before, but I would like to mention it again so that the post is self-contained: OSD700 is a course option offered at the college that I am studying, Seneca College. Despite it being a course that counts toward a graduation, we almost never discussed about marks and how I will be graded. The professor in charge of the course stated one thing clearly, "as long as you are contributing and you are showing the effort, you will pass this. Do your best."
The course description does not do justice to the responsibilities that you are given. OSD700 is described as a course where you will have to maintain an open-source project, but there's an important asoect here that it is never mentioned: what does it mean to maintain an open-source project?
Open-source projects and its challenges
Some people may never be interested on maintaing an open-source project, due to the self-sacrifice required. Since it is an open-source project, you should not be expecting to get paid at all. Maybe you could be lucky and open a successful donation campaign, so that you can give full-time attnetion to the project. In other situations, however, the project is a side thing, since you have to focus on your full-time job, right?
In my case, I was able to focus on this course like a full-time job, since I had a light courseload. However, it doesn't matter if you are a full-time or part-time maintainers, the challenges are still the same, they just have to prioritized quite differently.
What are those challenges?
For starters, you have to prioritize what you want to focus at a given time. Assuming you are a full-time maintainer, the ideal is that you can give your best on all areas, but that's just an idealization. Most of the time, you have to give up more work than you thought.
Maybe you had an idea you wanted to implement, so you, all excited, start implementing a prototype. You notice that to realise it to your vision will take more time, so what do you do? If you believe in the cost-sunk fallacy, you might think that it is better to keep developing it until you reach that vision. However, all that time that you spent on developing that feature is time that could have gone to bug-fixing, paying off technical debt, finding bugs to file, or any other tasks that'd still improve the overall health of your repository. So, at the end, you swallow up your pride and say: "it is time to give up on this." It may sound somewhat defeatist, but I think acknowledging that other things have to prioritised is part of what it means to be an open-source maintainer.
Another challenge is the one of not knowing what your end goal. For a lot of people, not knowing where they would end up after embarking on an adventure can provoke anxiety; the uncertainty of it all always make you asking, "am I in the right path?"
However, instead of being scared of that adventure for the rest of your life, there are two opposite views on it:
- Find a way to set an end goal, and focus on that end goal until you reach it. When you reach it, try to set another end goal.
- Let the adventure take you wherever it may lead you, and just enjoy it.
The first one may work with people who already have experience on a particular set of problems and they would like to have something finished, while the second one is for the people who enjoy the journey more than the treasure at the end.
However in an open-source project, you may need both: you want to get things done, so that others find your project useful, but you also would like to explore and enjoy what you learn along the way, since that will help to stimulate your creativity and develop a new way of solving the problem (and it may help keep your mind from going insane out of boredom).
One more challenge that one may encounter is having to communicate your ideas with your fellow maintainers, if you are in team. The idea is that you are hopefully on a collaborative environment, where everybody is willing to listen to anybody. However, just willing to listen is not enough. You gotta communicate your ideas, even if you think they are bad or that they don't solve the problem. Why? Well, they help you grow as a developer. If your teammates can justify why a certain solution may not be suitable to a specific problem, then you can use to your advantage and learn from their way of thinking. Developers can create more robust code by listening to several situations and cases, so I think that developers can have more robust critical and logical thinking by listening to other ways of solving the problem.
A little bit of retrospective
Back when I started this semester, we were supposed to write a blog about the areas we would like to contribute the most, and being on charge of those areas, too.
In my post, I talked about documentation and dependencies. However, throughout the semester, I mainly focused on the dependency visualization project.
At the start, I had this cool idea of the dependency tree that you could navigate through to discovery all of the dependencies that Telescope uses, but this idea was just cool; in terms of functionality and usability, it was horrible.
After all, the main purpose of the dependency visualization was to make it easier to find GitHub links for other people, so finding an easy way to navigate through hundreds of dependencies was the most important choice. However, before the front-end arrived, we had to write a service that could provide the information that the front-end would need. The service is not that big, and it actually does very little on its own, so it was a manageable project.
Some opinions regarding the dependency-discovery
service
If I have to be honest, I want to improve the dependency discovery service. I feel that the API can be improved and better defined. Also, the handling for exceptional cases is almost none, so there's that...
In terms of projects, this is probably the first project I was given total freedom on how to implement and how to design. I was just given a set of requirements, the rest was left for me to figure out, which was somewhat difficult to deal with.
Throughout my life I was always given a task to do, and they told how they want it to get it done, and I was able to follow just that. However, in the real world, most people that tell you what they want you to do are speaking from an area of expertise. Their solution might not be possible to realise, or their solution might not be one at all. This is why they tend to leave certain things vague: they just don't know what to do on a specific case or they might not know that that specific case actually exists. This is somewhat vexing for computer programs that could accept any kind of input, because essentially, you have what some might consider undefined behaviour.
I am aware that the phrase undefined behaviour has a technical meaning when discussing the safety of C programs, but I would like to take the phrase and view it more literally. When something that could happen in a program were to actually happen and you are not sure what the program may actually do, that is what I mean by undefined behaviour. It's the behaviour of a program that is never documented nor expected, and so it ends up being undefined. it is not like this behaviour does not exist, it's just that it is hidden, arising from the consequences of your program. This is where a lot of bugs could occur (in fact, all hidden bugs on a program are due to this phenomenon).
I hate that type of undefined behaviour. Why? Because I hate unreliable programs. If computers are fast, why can't they be correct, too? If I am going to type random words on my text editor, I don't want it to crash on me because I accidentally wrote typed too many keys at once. As the user, I don't know how the program behaves, so I am expecting that, as long as I don't do anything that is apparently unsafe for the program (turning off my entire computer during an update), I am fine with how the program does things. Of course, if the program can prevent any bad consequences even from those unlikely situations, even better, but that's not a strict requirement.
However, as a developer, when you are discovering what your program has to do, an important question always lingers in your head, "will I need this in the future?" Some people say yes, some people say no. Either way, the answer to this question cannot be boiled down to a simple yes or no, but instead it is reduced to the conclusion that the developer can make after years of experience, and even after that, that conclusion might turn out wrong.
In terms of my set of experiences, I cannot provide an answer yet.
What's left of the dependency-discovery
?
A lot of stuff, actually.
First of all, we gotta improve how the service itself works. Maybe a way to improve memory usage, since we cannot store so much information at a time, even though we would like to to save on GitHub calls...
We could improve on the current API so that it is easier to use. For example, the /projects
route does not provide pagination, so you will get all names at once, which can be annoying for interfaces implementing pagination on their end.
Another thing that could be done is to research what other functionality might useful for the service. This might not be necessary to do, since the service had a single purpose, but if this is an API that other clients could consume, maybe we could try to expand more on what could be possible with this service.
Final words
What's left to say? Probably a lot, but I don't want to make a 20 minute read, since that'd me just rambling on and on and on about certain topics related to my experiences on this.
I would like to end this post by thanking everybody who participated in the OSD700 course and gave their support to bring Telescope to version 3.0. Best wishes to everybody!
