Try a Different Version

Back when I was still working for a large enterprise company, I did a lot of code reviews. This particular organization didn’t have much interest in code quality, so a lot of the code I was reviewing was just… bad. Often, I wouldn’t even need to read the code to see that it was bad.

In the olden times, inconsistent or unclear indentation was a great sign that the code would be bad. As IDEs started automating indentation, you lost that specific signal, but gained a new one. You can just tell code is bad when it’s shaped like this:


Don't be so Negative Online

It's fair to say that regardless of their many advantages, "systems languages", like C, are much harder to use than their more abstract cousins.Vendors know this, which is why they often find a way to integrate across language boundaries. You might write critical functions in C or C++, then invoke them in Python or from Swift or… Visual Basic 6.

And crossing those language boundaries can pose other challenges. For example, Python has a built-in boolean type. C, for quite a long time didn't. Which means a lot of C code has blocks like this:

This is Your Last Birthday

by in CodeSOD on

I have a philosophy on birthdays. The significant ones aren’t the numbers we usually choose- 18, 21, 40, whatever- it’s the ones where you need an extra bit. 2, 4, 8, and so on. By that standard, my next birthday landmark isn’t until 2044, and I’m a patient sort.

Christian inherited some legacy C# code which deals in birthdays. Specifically, it needs to be able to determine when your last birthday was. Now, you have to be a bit smarter than simply “lop off the year and insert this year,” since that could be a future birthday, but not that much smarter.


Is We Equal?

Testing for equality is hard. Equal references are certainly equal, but are equal values? What does it mean for two objects to “equal” each other? It’s especially hard in a language like JavaScript, which is “friendly” about type conversions.

In JavaScript land, you’re likely to favor a tool like “lodash”, which provides utility functions like isEqual.

Remember Robert, the student who ruined his class curve back in the 1960s? Well, proving the old adage that the guy who graduates last from medical school is still a doctor, he managed to find another part-time job at a small hospital, earning just enough to pay his continued tuition.


Classic WTF: A Char'd Enum

by in CodeSOD on
It's a holiday in the US today, so we're reaching back into the archives while doing some quarantine grilling. This classic has a… special approach to handling enums. Original. --Remy

Ah yes, the enum. It's a convenient way to give an integer a discrete domain of values, without having to worry about constants. But you see, therein lies the problem. What happens if you don't want to use an integer? Perhaps you'd like to use a string? Or a datetime? Or a char?

If that were the case, some might say just make a class that acts similarly, or then you clearly don't want an enum. But others, such as Dan Holmes' colleague, go a different route. They make sure they can fit chars into enums.
