A Principal Software Engineer at Epic Games / 25 Year Vet, talks about why AI is just a "giant switchboard" and why code is a delicate crystal.

I’ve been thinking a lot about how people actually get comfortable with complex topics like programming, not by tutorials, but by just being passively around the conversations.

So I recorded one of those conversations.

I sat down with Dietmar Hauser (25+ years in the industry, Principal Software Engineer at Epic), and we went from Commodore 64 days, literally typing code out of magazines. All the way to modern C++ and where we find ourselves at the moment with another layer of abstraction = LLMs.

What stuck with me wasn’t just the history, but how he talks about coding as this fragile, interconnected system (“a delicate crystal”), that shatters if you touch the wrong thing, which i found very interesting.

It’s a long, unfiltered discussion, more like something you overhear between two people deep in the field than a structured interview.

If you’re trying to get a feel for how experienced engineers actually think about code, or if you wanna warm up to the idea, this convo might be useful:

boost::container::hub ACCEPTED into Boost

Hi to all, I'm glad to announce that the proposed boost::container::hub container has been ACCEPTED. Congrats u/joaquintides !

More details here:

https://lists.boost.org/archives/list/[email protected]/thread/7WZ7QTPE2YDYD5OYCKXKKV2N74JHJRZL/

Reminder:

hub is a sequence container with O(1) insertion and erasure and element stability with great performance (see these benchmarks): pointers/iterators to an element remain valid as long as the element is not erased. hub is very similar but not entirely equivalent to C++26 std::hive (hence the different naming, consult the section "Comparison with std::hive" for details).

I tried compile-time heapsort in TMP. It basically became selection sort.

Tried implementing compile-time sorting with old-school TMP (recursive templates, no constexpr). Yeah, constexpr sort exists now, but I wanted to see how far pure template recursion could go. Quicksort and mergesort worked fine. Heapsort was the one that broke.

Then it clicked: heapsort assumes cheap random access. Parent node, left child, right child, all index arithmetic. But in a typelist like arr<5, 3, 8, 1> there's no arr[i]. Every element access peels the head off recursively, so it's O(n) per lookup. Heapify becomes expensive, sift-down becomes expensive, and the whole thing degrades.

What I actually ended up with was... selection sort. Find the min by scanning the whole list, pull it out, recurse. O(n²) template instantiations. Not great.

Quicksort doesn't have this problem because it just filters into two sublists (less-than pivot, greater-than pivot). No indexing needed. Mergesort splits with take/drop which is O(n) but only happens once per level, so it stays O(n log n) overall.

I didn't really clock the random access dependency until I was halfway through writing the heap version. Felt kind of dumb in retrospect. Never really felt how much big-O depends on the data structure until TMP took away my arrays.

Full code in comments if anyone wants to look at it. Fair warning the mergesort lives in namespace www because I was iterating on these in separate files and never bothered renaming.

Anyone else run into algorithms that stop making sense in TMP?
