Found: the dial in the brai=
n that controls the immune system (6 minute read)
Scientists have identified the brain ce=
lls that regulate inflammation and determined how they keep tabs on the imm=
une response. The neurons that act as the master dial for the immune system=
live in the brain stem, the stalk-like structure that connects the bulk of=
the brain to the spinal cord. The finding could lead to treatments for aut=
oimmune diseases and other conditions caused by an excessive immune respons=

to regulate inflammation remains unclear.

offset-allocator (GitHub Re=
po)
offset-allocator is a fast, simple, and=
hard real-time allocator especially useful for managing GPU resources. It =
is a port of Sebastian Aaltonen's OffsetAllocator package for C++, rewritte=
n in 100% safe Rust. While the general algorithm in the crate could be adap=
ted to construct a Rust allocator, this is beyond the scope of the implemen=
tation. offset-allocator is completely agnostic to what it's allocating. It=
only knows about a contiguous block of memory of a specific size.

Not all Graphs are Trees (6=
minute read)
Relational algebra can easily be repres=
ented as trees as formulas are already structurally rooted trees where each=
operator has its inputs as children. Things get more complicated when intr=
oducing non-tree structures, like some kind of self-join. This can be resol=
ved using inlining (simply duplicating the expression you want to reference=
twice) or let binding. Common methods to open up unrestricted access to re=
present graphs containing cycles in programs include self-referencing, usin=
g a fix point operator, and explicitly listing edges.
