If you’ve ever written software, you probably already know where this story is going.
If you haven’t, here’s something you should know:
Sometimes the smallest problem takes the longest to fix.
You can build an entire feature in an afternoon.
Then spend three days trying to figure out why one button occasionally doesn’t work.
Welcome to software development.
It Should Have Been Simple
It usually starts innocently enough.
Something isn’t working.
You look at it and think:
“Oh, I know what that is.”
You change a line of code.
Run the app.
Still broken.
Okay.
Maybe it’s this other thing.
Change that.
Run it again.
Still broken.
A couple of hours later, you’ve changed twelve things, read documentation written six years ago, searched through old discussions, and somehow learned the life story of a developer in Germany who had a vaguely similar problem in 2019.
But your bug?
Still there.
At this point, coffee becomes less of a beverage and more of a development tool.
Then You Start Questioning Everything
This is the dangerous stage.
You’ve checked the obvious things.
Twice.
Then three times.
So you start looking deeper.
Maybe it’s Android.
Maybe it’s Windows.
Maybe it’s the email server.
Maybe it’s the database.
Maybe it’s the network.
Maybe some obscure library changed something.
Maybe it’s a race condition.
Maybe the computer simply doesn’t like you today.
Eventually you reach the stage every developer reaches:
“This makes absolutely no sense.”
That’s usually when things get interesting.
Fix One Thing, Break Another
Sometimes you actually find a solution.
Great.
You run the app.
The bug is gone.
Victory.
Then you notice something else stopped working.
Fantastic.
So now you fix that.
Which brings the original bug back.
There are moments in software development when closing the laptop and becoming a goat farmer starts sounding surprisingly reasonable.
But you keep going.
Because now it’s personal.
That bug has challenged you.
And apparently you’ve decided you’re not going to sleep properly until one of you wins.
The Worst Bugs Are the Ones That Hide
A bug that crashes every time is actually a pretty good bug.
I know that sounds strange.
But at least it’s consistent.
Press this button.
Crash.
Great.
I can reproduce that.
The really frustrating bugs are the ones that work perfectly while you’re watching.
You test something fifty times.
Perfect.
Give it to someone else.
Broken.
They send you a message.
You try it.
Works.
They try it.
Broken.
Now you start asking questions that sound ridiculous:
“What exactly did you do before you pressed the button?”
“Was the phone plugged in?”
“Were you on Wi-Fi?”
“Which screen did you open first?”
“Was there a full moon?”
At some point, nothing feels unreasonable anymore.
Then You Find It
And this is the funny part.
After hours—or sometimes days—of digging through everything…
You find the problem.
One line.
One setting.
One tiny assumption you made three months ago.
Maybe something happened in a different order than you expected.
Maybe a value wasn’t available yet.
Maybe one character was wrong.
You stare at it.
You fix it.
Run the app.
It works.
Run it again.
Works.
Twenty more times.
Still works.
And for about thirty seconds you feel like the smartest person alive.
Then you remember it took you three days to find it.
So maybe we shouldn’t get carried away.
But Those Three Days Weren’t Wasted
This is something I’ve learned to appreciate.
When I first started programming, spending hours chasing a bug felt like lost time.
Now I’m not so sure.
Because while looking for that one problem, you learn a lot about your own software.
You discover parts that could be cleaner.
You notice assumptions you shouldn’t have made.
You find other little problems before anyone reports them.
And most importantly, you learn something that makes the next bug easier to find.
Usually.
Let’s not make promises.
This Is the Part Nobody Sees
When you download an update and the release notes say:
“Bug fixes and improvements.”
That might represent five minutes of work.
Or somebody might have spent three days staring at a screen wondering why a value was null only on Tuesdays.
You don’t see that part.
And you shouldn’t have to.
That’s the job.
You should just install the update and discover that something works better than it did yesterday.
Actually, if I’ve done it properly, you might not notice anything at all.
I’m perfectly happy with that.
Building Software Is Mostly Problem Solving
People sometimes imagine programming as sitting at a computer typing code incredibly fast.
There is some typing.
But a lot of the time it’s more like detective work.
Something happened.
You don’t know why.
You gather clues.
You test theories.
You eliminate possibilities.
You occasionally accuse the wrong suspect.
And eventually you find the tiny thing responsible for the whole mess.
Then you fix it.
Until the next mystery appears.
And there will always be another one.
That’s okay.
Because there’s a strange satisfaction in finally solving something that refused to make sense.
It’s probably one of the reasons I keep doing this.
Build something.
Break something.
Figure out why.
Fix it.
Learn something.
Make another coffee.
Repeat.
That’s software development.
Until next week,
