We use the "webpackChunkName" magic comment in a few places and lost all the benefits of the dynamic import.

Is turbopack worth it? We're considering switching back to webpack because it works more predictably and has worked for years.

Wow. That's a slap in the face to her constituents and neighbors. Very poor taste.

After using my Apple Wallet for all my Paris Metro tickets, I was forced to buy a reloadable physical card to get my airport ticket. One final micro FU from the French as God intended.

Wow, thanks for sharing! I had no idea these were all part of the same project. I wonder if there's appetite for more large spanning projects with the incoming administration.
