RT @BarryRevzin: C++26 is going to have Reflection!. I am very excited about that fact, so I wrote a new #cpp post with a very cool example….

I've just posted a long old update about my plans for the Flux library, focusing on ease of use, performance and a potential future standardisation effort. I'm keen to get feedback at this stage so please have a read and leave a comment if you so choose.

Flux has been around for a couple of years now, and the feedback I get is mostly that people seem to think it's pretty good. I think it's pretty good too! But I'm also aware that the cu...

“But if you want a solution now — use Flux”.
This new #cpp post started out when I was trying to investigate how to use token sequence injection to solve the internal iteration problem. This was an extremely mild-melting experience to implement — so hopefully it is just as fun to read! .

I had high hopes for #chessmasters because @DavidHowellGM is the best commentator in the business, but that was… really, really not great. Would it be too much to ask to actually show some chess?.

I've found the last few days pretty tricky, so #AdventOfCode day 18 was a nice change of pace. Dijkstra's algorithm came up a couple of days ago so I had an implementation ready to go, and then std::partition_point() does all the hard work for part 2. I like this one!

Ah, #AdventOfCode day 13, in which I fail to spot that we're solving a system of two simultaneous equations despite allegedly holding multiple degrees in mathematics AND WRITING THE EQUATIONS DOWN IN FRONT OF ME 🤦♂️. I got there in the end though.

Exponential growth was the enemy in #AdventOfCode.today! . A simple vector was good enough for part 1, but more iterations in part 2 required a different approach. I went for storing the data in a (value, count) hash map, which worked very well. A nice puzzle!

No #AdventOfCode screenshots today as my code is super messy and not worth showing off. But it was very satisfying taking the initial 5 minute(!) runtime for part 2 down to ~70ms on my laptop.

Day 5 of #AdventOfCode felt kinda like cheating once I realised that the rules give us an ordering that we can use as a comparator with sort()/is_sorted(). Using a hash set gives about a 10x speedup versus a sorted vector + binary search, but the latter is plenty fast enough

Day 4 of #AdventOfCode and we're solving word searches! . Part 1 had me scratching my head for a little while, because I didn't account for the fact that an 'X' can be the root of more than one 'XMAS'. Fortunately part 2 was less tricky.
