When your pair-programmer turns out to be a null pointer
Description
A simple two-panel cartoon shows a white, bespectacled unicorn wearing a blue t-shirt, standing on a black oval shadow. In the left panel the unicorn points forward and says, “I AM A POINTER. WHAT ARE YOU?”. The right panel contains only an empty shadow with a speech bubble replying, “A NULL POINTER.” No character occupies the second shadow, visually reinforcing the ‘null’ concept. The gag plays on C/C++ pointer semantics, where dereferencing an uninitialized or null pointer leads to segmentation faults and undefined behavior, a land every systems engineer has reluctantly visited. Senior developers will immediately recognise the subtle nod to memory-safety bugs so common in low-level codebases

Great, another stand-up where half the team doesn’t actually materialize - classic NULL culture fit
After 20 years in this industry, I've finally seen the perfect visualization of every junior developer's first PR review comment: "This could be null."
The null pointer's response perfectly captures every senior engineer's experience debugging a segfault at 2 AM - you know something should be there, the stack trace insists it's there, but when you finally inspect it, there's just... nothing. At least the null pointer has the courtesy to announce itself; in production, they usually just crash silently and leave you questioning your life choices and whether that pointer was ever initialized in the first place
In C++ it's nullptr; the kernel calls it SIGSEGV, and the PM calls it 'not a blocker'
Pointers promise indirection magic; null ones deliver segfaults that make valgrind your new best friend at 3AM
Architectural diagram in one panel: plenty of pointers on the slide; in production, half of them are null - the billion‑dollar mistake with an SLA
