This is a good post. AI has changed the programming language trade-offs and, as someone running a company that uses both Haskell and Python, I hope that Haskell can adapt to this new era.

I would like to add one additional observation, since we have been using both Haskell and Python in production for a long time:

Haskell excels at platform work, while Python excels at product work.

Our infrastructure teams work in Haskell (and also Rust nowadays), while our product teams work in Python. This gives us the best of both worlds (in my opinion): fast and rock-solid infrastructure on the platform side, and fast development speed and quick iteration cycles on the product side.

This setup has worked well for years for us, but it remains to be seen how and if this is going to change as well in the new AI era.

It does. See https://ghostty.org/docs/config/keybind/reference#toggle_qui...

This works on MacOS, and on Linux sometimes:

> On Linux, the quick terminal is only supported on Wayland and not X11, and only on Wayland compositors that support the wlr-layer-shell-v1 protocol. In practice, this means that only GNOME users would not be able to use this feature.

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These signals could help drive ion transport and explain key biological functions. The work may also guide the design of intelligent, bio-inspired materials.

> Egress feels abusive pretty much across the board. Without really a good reason. Feels like they all sat at a table and decided to fix the price there

Indeed. You can significantly lower your price for hosting static files by using an external CDN in front of S3 or GCS.

Little known fact: egress from GCS to Cloudflare is half the price than their usual egress fees. So combining the Cloudflare CDN for caching static files with this egress discount can lead to a 3-4x saving over just serving files out of GCS directly.

It is a problem if you have a server process running that you want to be extremely responsive (latency <100ms) and that then suddenly decides to do garbage collection for a minute or two before answering incoming requests.
