Here I’m especially thinking about little side projects where you want to get the thing done pretty efficiently. + +When I start on a new project using some technology I haven’t worked with before, I often: + + 1. Find some code on the internet that already does something a little like what I want + 2. Incrementally modify that code until it does what I want, often completely changing everything about the original code in the process + + + +Here are a couple of quick thoughts about this process: + +### it’s important that the initial code _works_ + +Often when I’m out looking for examples, I’ll find a lot of code that I can’t get to work quickly, often because the code is kind of old and things have changed since then. Whenever possible, I try to find code that I can get to work on my computer pretty quickly. + +It’s been pretty helpful to me to give up relatively quickly on code that I can’t get to work right away and look for another example – often there is something out there that’s more recent and that I can get to work more quickly! + +### you have to be able to incrementally change the code into what you want + +Today I’ve been working with some neural network code, and one thing I’m really struggling with for the last couple of days is that I find it pretty easy to find somewhat relevant Jupyter notebooks that do RNN things, and pretty hard to modify those examples to do something closer to what I want. They keep breaking and I then don’t know how to fix them. + +Last week I was working on a Rails app, which I think is something that’s very easy to incrementally change into the program you want: `rails new` gives you a webserver that does almost nothing, but it works! And then you just need to change it one tiny step at a time into the website you want to build. + +### examples of “something that works” + + * If you want to write a window manager, [tinywm][1] is a window manager in 50 lines of C! + * this tiny kernel written in Rust that does nothing was a fun starting point for an operating system (probably it’s not a good starting point today) + * `rails new`, like I talked about above + * I love that projects let you “view source” on the backend of any Glitch project + * Jupyter notebooks, like [these great NLP tutorials by Allison Parrish][2] + + + +### that’s all! + +I think little starting points like this are so important and can be really magical. Finding the right starting point can be hard, but when I find a good one it makes everything so much easier! + +-------------------------------------------------------------------------------- + +via: https://jvns.ca/blog/2020/11/18/how-to-do-hard-projects--start-with-something-that-works/ + +作者：[Julia Evans][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://jvns.ca/ +[b]: https://github.com/lujun9972 +[1]: http://incise.org/tinywm.html +[2]: https://twitter.com/aparrish/status/876117075567284225
