The Julia Language

When zipping with a product iterator with no arguments (which produces only one output, the empty tuple), it seems the check for zip completion does not handle this case:

julia> for (z,) in zip(Iterators.product())
       @show z
       end
z = ()
ERROR: ArgumentError: tuple must be non-empty
Stacktrace:
 [1] first(#unused#::Tuple{})
   @ Base ./tuple.jl:140
 [2] _pisdone
   @ ./ite

In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange. I set max_date_allowed = datetime.today().date(), but in the calendar, yesterday is the maximum date allowed. I see it in my apps, and it is also present in the first example on the DatePickerRange documentation page.

We have a couple of combinations of let and global that are not analyzed correctly, like:

let
	a = 1
	global a = 2
end

defines a global a, but Pluto prioritizes the let block.

@test_broken means that we still need to fix it:

This is a good firs

A common request when teaching LP101-type classes is for sensitivity reports similar to Excel solver.

Here is a suggestion from someone who teaches these types of classes:

This shouldn't happen

using Plots
plot(rand(4,4), layout = 2, series_annotations = [1 2; 3 4])
Error showing value of type Plots.Plot{Plots.GRBackend}:
ERROR: type Array has no field baseshape
Stacktrace:

This should be a good beginner issue :)

I found that function mod2pi is not implemented yet, but mod works. Is there any list of implemented functions? Minimal working example is:

using Zygote

# This is working
gradient(x -> mod(x, 2pi), 1.)

# This is not
gradient(x -> mod2pi(x), 1.)

Unlike all the existing charts that graph a string (most likely) against a number, this graphs numbers on both axises. So in addition to the configuration changes needed for passing the right field to chartjs, the PR for this should also change the "preferred type" to "number" for the x axis when the chart type is scatter plot.

In order to profile and optimize the current inference server architecture and best tune its hyper-parameters for various applications, it would be very useful for AlphaZero.jl to have a mode where it outputs a debugging timeline in which it is possible to easily visualize when each worker submits an inference request, when it gets an answer, and when inference concretely runs on the GPU (along wi

If I run the copy&paste examples, such as https://mtk.sciml.ai/stable/tutorials/acausal_components/ :

using ModelingToolkit, Plots, DifferentialEquations

@variables t
@connector function Pin(;name)
    sts = @variables v(t)=1.0 i(t)=1.0 [connect = Flow]
    ODESystem(Equation[], t, sts, []; name=name)
end

function Ground(;name)
    @named g = Pin()
    eqs = [g.v ~ 0]
    

In Exercises 10.1, the outer product in Take the outer product of a vector v with itself and assign it to variable cross_v should be cross product.
