| @aplund:matrix.org | I'm trying to use the DifferentialEquations.jl package on a fresh install, but I keep getting this error:
Failed to precompile DifferentialEquations [0c46a032-eb83-5123-abaf-570d42b7fbaa] to "/home/lund/.julia/compiled/v1.9/DifferentialEquations/jl_oGg5uu".
ERROR: LoadError: InitError: could not load library "/home/lund/.julia/artifacts/cb7fc2801ca0133a5bdea4bc4585d07c08284cfa/lib/libsundials_sunlinsolklu.so"
libklu.so.1: cannot open shared object file: No such file or directory
I've tried a couple of times removing things and starting again, but same error. Should libklu.so.1 be available on my platform, or is it meant to be in the package?
| 04:52:31 |
| @aplund:matrix.org | oh... I see. I have libklu.so.2 not .1. | 04:53:53 |

 @ericjmorey:matrix.org | What are your opinions on pluto.jl? Do people tend to just use jupyter? | 20:54:37 |

 @hasnep:matrix.org | It does depend on the style of code you're writing, but personally I can't stand Jupyter and only use Pluto | 03:09:40 |
| @hasnep:matrix.org | I think most of the Julia community uses Pluto too, but there's some things it doesn't handle well, e.g. long running calculations like simulations, or code with lots of variable mutation | 03:10:32 |
| @hasnep:matrix.org | I miss Pluto every time I have to make a notebook with Python, I should just use Pluto and PyCall.jl 😂 | 03:12:09 |
| @ericjmorey:matrix.org | I'm not sure what I think of either, but the bit I've used Jupyter has left me a bit frustrated. | 03:22:55 |
| @hasnep:matrix.org | I find Jupyter annoying because of the statefullness, I don't like the idea that I could delete some code that I needed and break the notebook without knowing | 03:26:43 |
| @hasnep:matrix.org | So when I use jupyter I'm constantly restarting the kernel and rerunning all the cells from top to bottom | 03:28:22 |
| @hasnep:matrix.org | Pluto just does all that for me automatically, and without rerunning stuff that hasn't changed! | 03:28:54 |
| @ericjmorey:matrix.org | Thanks for sharing! | 14:15:51 |

 Andreas Weh | Pluto plays also much nicer with `git`.
Jupyter got much better with the latest major release. But for teaching and short running things I still prefer Pluto. | 21:13:45 |
 qwjyh | Pluto with PlutoUI is a really great framework for small interactive application. Unlike jupyter, cell ordering doesn't affect execution ordering, so you can put use interfaces at the top and logics later. | 21:25:46 |

| rollskatflat | Hi, I am new to Julia, but have done plenty of MATLAB and scientific Python in my time.
I am just trying to understand how to vectorise an execution.
a .* b works just fine.
But now I have created a Vector{SVector} from the Rotations.jl package
I have used
push!(myVec, mySVec)
To build the data structure | 10:41:03 |
| rollskatflat | I then create a rotation matrix using QuatRotation, to create the quaternion.
myQuat * myVec[1]
Returns a result as expected
As do all subsequent indices
But, when I go
myVec .* myQuat | 10:42:39 |
