Exactly my thought too. The offset is just the zero frequency. But in general, the need to do this for the zero frequency would suggest that there's a scaling problem for all the longer frequency Fourier components? And…
I'm not sure we're disagreeing here? As I understand it, some people have a certain kind of distractable brain and there's an underlying brain chemistry implicated here which isn't something you develop in adulthood.…
ADHD is a developmental condition which is highly genetic and relates to neurotransmitter brain chemistry (Dopamine / Norepinephrine). People with ADHD have it their whole life, it's not something you can develop in…
This is from to the history of how the Julia language was bootstrapped. The fact that Jeff happened to have written his own scheme (femtolisp) as a previous project probably helped :-) Actually it's not just the parser…
Have you tried Infiltrator.jl? It's great for breaking out into an interactive REPL from some inner scope, allowing you to examine the local variables and other program state interactively. This covers the part of the…
Yes, well put. I'd take it further - in numerical code there is no real distinction /at all/ between closed form vs iterative solutions. Every type of numerical code is subject to truncation error; an iterative method…
This is really neat. In the past I've used similar techniques to decode binary data from a third party lidar system in parallel. In a way that the manufacturers probably didn't intend or expect. The system generated…
The piston idea seems like a appealing design requiring minimal new technology. The plant is the same as existing pumped hydro plant, the weight can come from the native rock. Using a rolling membrane for the seal is…
No, I'd say it was an almost-complete success. The point of this was to test several things which they've never tested before and gather data to drive design improvements. They successfully tested: ascent under three…
Punning through the union is explicitly allowed in the GCC documentation which explains why it's reliable for use in the Linux kernel. See https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#Typ... > you also have…

I liked the following blog post where Jack Lindamood argues pretty convincingly against using Context.Value in nearly all circumstances, and gives some nice alternatives.…
Agreed, treating log events as a string seems like throwing a lot of readily available information away. There's various logging libraries which do allow more structure but too often this is ignored. I think we got some…
I agree the exterior algebra is beautifully elegant mathematics, but expressive elegance of the formalism is largely irrelevant to numerical robustness. (Cramer's rule itself is a perfect example of this: it's…
"Static" is a reference to the size of the arrays being fixed and encoded in the type. There's various allocation strategies, for instance StaticArrays.SizedArray uses a normal heap-allocated Array as the storage. That…
A year or so I looked into "git for data" for medical research data curation. At the time I found a couple of promising solutions based on wrapping git and git annex: GIN: https://gin.g-node.org/ datalad:…
Current MR physicist / data scientist here. There seems to be a lot of misapprehension in this thread. First, this work is about taking data in the sensor domain ("k-space") and reconstructing it into an image. Doing…
Julia has been excellent for shelling out since almost the beginning. See https://julialang.org/blog/2012/03/shelling-out-sucks
The models you'd use for map making are often really simple. For example, the Australian plate motion model is a "seven parameter transformation" - three translations, three rotations and a scale factor. The deformation…
Have you seen https://github.com/sciapp/gr ?
This has been vastly improved fairly recently with the advent of the tensorflow-gpu meta package available via conda. See https://towardsdatascience.com/tensorflow-gpu-installation-m...
This is one of the main things which has driven the development of julia's logging system; it seems that some people just don't like debuggers very much (I'm one of them) and find staring at logs and attempting to run…
I second that, the CMOG channel is great. They have high production quality (especially consider the constraints of the glass shop) and really talented artists / craftspeople. Bill Gudenrath's series on Venetian…
My feeling is that Flux is a fantastic tool for playing with innovative models which can't be expressed in the usual frameworks. And quite possibly already the best thing that exists for open ended experimentation in…
Hah, that someone was me, I'm glad it clicked for you! I had a similar experience of it "just working" when trying a few weeks ago. I particularly enjoyed being able to build and run Flux models interactively just like…
