The current interface for selective reading is to use **filters**
The approach works well when the filters are simple (field in (v1, v2, v3, …), and when the number of columns in small. It does no…

For performance-related course (execution time of sorting algorithms, number of cycles to execute a loop, number of cache misses in a code, ...), we'd like students to get the same "numbers". This als…

How should we define the scalar trait? I'd like to keep it very general. It would be cool for example to support operators over finite fields, etc.
The `Num` create provides a fairly generic numer…

When HETS computes a colimit, it produces new constants, and these have opaque names like "gn_n6"
To make the complex numbers example more readable, Ewen is spotting these in the output, figuring out…

I was getting ambiquos results using sympy, and it all boiled down to the issue that can be reproduce by the following simple code.
`import sympy as smp
from sympy import sqrt
x = smp.symbols('…

`Integers.as_relational(x)` gives the following output:
```python
>>> Integers.as_relational(x) # and similar for Naturals and Naturals0
(-oo < x) & (x < oo) & Eq(floor(x), x)
```
But it should…

[This was found in zephyrproject-rtos/zephyr/issues/63417 (which is fixed now) but it's not related to it. It was also filed earlier in zephyrproject-rtos/zephyr/issues/67035 but I don't think it's re…

The constituents of a multi-sublattice phase listed in a DAT can be chemically complex or contain information about the charge state of the constituent, or really anything else at all. [See here for a…
