While Gelidium seaweeds can be collected by gathering fragments washed ashore, mass production of agar requires steady, large quantities.10 Harvesters in New Zealand during WWII had to “walk beside a boat, waist to armpit deep in water and feel for the weed with their feet.” Handling large volumes of wet seaweed (which yields less than five percent agar) was challenging. Then as now, when Gelidium is harvested by scuba divers from rocky seabeds, collectors have to understand the life cycle of the algae, find the most likely locations for its growth, and prevent overharvesting to safeguard future yields.
An object’s OID is computed the same way git does it, SHA1(" \0"), using pgcrypto’s digest() function, and refs get compare-and-swap updates through SELECT FOR UPDATE. A libgit2 backend registers these tables as its storage layer, and if the protocol really is separable from the format, a normal git client should be able to push to and clone from a Postgres database without knowing the difference.

Instagram is adding a new alert for the parents of teen users of its social media platform. The network will alert the adult if their child repeatedly searches for terms about suicide or self-harm in a short time frame. From that notification, the parent will optionally be able to access resources for having conversations with their teen about these topics. These alerts will begin rolling out for parental supervision users in the US, UK, Australia and Canada next week, with later regions to be added in the future.
