I've had issues with FINA/AQUA points as a normalization metric for a long time. But in looking at the World Cup results in Carmel, where AQUA points is used to determine prize money, I thought it was worth complaining about. With a provocative title: https://t.co/HMnGCM0AJP

The World Aquatics point system has its benefits, but it undervalues athletes like Gretchen Walsh who are leagues ahead of the field.

This tweet makes it seem like Jonathan's talk was _about_ this feature, I simply meant to say that this particular slide was about it.

Sometimes, working on C++ is frustrating. Other times, people gives talks about how a feature you pushed through is "really magical but also really convenient." Those latter moments make the former moments worthwhile. Check out https://t.co/w43VjycVA4

I'm going to giving a talk at @CppCon next month about Reflection. Come check it out! https://t.co/JkTuZCy5SG

One of the most memorable moments of these past Worlds was Summer's reaction to winning the 200 fly. In a good way! All of us wanted her to break THAT record. Of course she was... unhappy... with missing it by THAT much. Some people just don't want athletes to show emotions.
Go to the 9:11 mark in the race video, and see the 3rd slide of Summer's latest Instagram post...there was an interaction between the two in the water, the TV cameras just didn't frame it. Continues to be the dumbest drama of the World Championships. https://t.co/T9ORsnrmt6

New #cpp post. While we didn't extend support for constant template parameters in C++26, we did adopt reflection — which allows us to accomplish that as a library feature! How?? Been working on this for a few weeks, and am excited to finally share: https://t.co/wjHOzv4O4j

Ledecky was going so fast in this swim (3s under WR pace for a while) that she broke the graphics, they just got stuck reporting her at -0.43 for several laps... Ledecky: breaking everything there is to break in the 1500, since 2013.
During the third day of swimming at the 2025 World Aquatics Championships, Katie Ledecky won the women's 1500 freestyle in 15:26.44. This is her sixth world title for her in this event, and it is the 5th fastest performance of all time.

Fun way of looking this is to sort by total medals won: 1. 20 - Phelps 2. 16 - Lochte 3. 15 - Phelps golds 4. 14 - Sun Yang and Hacket 6. 13 - Cseh
The 2025 World Aquatics Championships start this week in Singapore! These are the 30 most decorated male swimmers in individual events in history - medals sorted by gold, then silver, then bronze. Who’s going to be the next swimmer to join this list?

The 25y pool I usually swim at is reconfigured for camps, so I had to swim crossways... so more like 15y a length, maybe less. Was taking 3-4 strokes a length freestyle. Not even a full stroke breaststroke. This must be what it feels like to be Léon Marchand. Was lots of fun.

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. We're taking a JSON string and turning it directly into a C++ object: https://t.co/ox3K3obxQ0

I went on a trip recently. We stopped to get dinner and they had professional darts on TV. Darts is absolutely not a more compelling spectator sport than swimming. Surely, we can beat... darts.
It's amazing how much progress has been made by "non-revenue" collegiate sports over the last few years when it comes to in-person and digital viewership of events... Wrestling? Sold 18,000+ tickets/day at NCAAs. Women's Basketball? 24M peak viewers for a game. Gymnastics?

It occurred to me recently that I could actually implement the Reflection TS on top of the C++26 reflection design (p2996). So I thought it would make an interesting #cpp blog post to compare the type-based to value-based models for reflection: https://t.co/vLvn6Z1or5

Frequently, whenever the topic of Reflection comes up, I see a lot of complains specifically about the new syntax being added to support Reflection in C++26. I’ve always thought of that as being...

I'm watching Nationals with my 3yo daughter, who loves watching swimming. @RowdyGaines circles Regan Smith on the screen and she immediately yells out "that's not a good circle!"

The final of the men's 200 back at Worlds this summer is July 1st. If Kos hits the mark then, that'll be 15 years, 355 days. I think pretty likely Peirsol's record survives the summer, so will soon age past Egerszegi's (on Jan 3rd next year).
These are the longest standing world record holders in a single event uninterruptedly in long course meters since the 1950s, when World Aquatics started to recognise world records only in metric measurements.

New #cpp post from me. I was inspired by a talk I watched recently to go implement a struct-of-arrays vector in C++ using Reflection. Have I mentioned that I am very excited about Reflection? https://t.co/Z614JHKJGl

Recently, I watched Andrew Kelley’s talk on Practical Data Oriented Design. It goes into some of the architectural changes he’s been making to the Zig compiler, with pretty significant performance...
