It's a common saying that the two most difficult tasks in development are naming and cache invalidation.
Inspired by this, I recently tweeted out the following question: https://twitter.com/josepheames/status/1196835125700354048
I got a crazy amount of response and thought it would be interesting to compile and categorize the responses. So, according to about forty developers, here are the hardest things in programming: (I tried to categorize and compile it intelligently)
First, I'll start with the purely technical items. Some of them are unsurprising. A few probably imply a current problem someone is working on…
- change detection
- dates and time-zones
- folder structure
- off by one errors
- picking and sticking to a front end framework
- macbook keyboards
- any problem involving linkage of two systems that expect certain things to
- match up
- data structures
- reading and understanding someone else's code in order to fix it
- for newer programmers, getting things working efficiently
- thread management and synchronization
- setup & config of a new language, library, or environment
- ignoring unit test coverage
- providing estimates
- threading (2 votes)
- working with legacy databases that lack referential integrity
Next are the architectural and design items. This is what I thought most people would reply with. I personally identify very much with much of this list:
- finding the balance between good architecture and over-engineering
- keeping things simple (2 votes)
- striking the balance between shipping code quickly and shipping quality code.
- choosing when to build/use abstractions. If you abstract too much you become an architectural astronaut if you abstract too little your codebase becomes
- unmanageable with copy-paste pasta, lack of consistency and just hard to understand (I REALLY loved how elegantly this was phrased)
- thinking before coding to avoid bad architectures
- avoiding duplicated code but also not over-engineering everything
Then we have the personal items. Things people struggle with internally. Perhaps here are some items you may personally identify with.
- choosing a side in the text editor, naming convention or tabs vs spaces holy wars
- remembering it's time to sleep
- taking the first step into the unknown
- the ever-increasing concept count of all tech
- remembering you don't have to learn everything
- balancing learning with productivity
- deciding what to ignore
- knowing when to stop
Finally, the items that have to do with groups and organizations. Here I compiled all the similar items, and ended up with the most common issue people said they believe is the most difficult task in programming.
- working as a team (6 votes)
- convincing people to design and implement with a11y and mobile-first mentality
Here, I compiled many variations of working as a team, from getting agreement to just a simple reply of "people". How interesting that the most popular answer (although only 6 of about 40 votes) was not really anything to do specifically with programming.
What do you think is the most difficult task in programming (besides the 2 exclusions)? Do you agree with this summary? Are people the most difficult part of your job?
