TIL Don't source a bash script that sets `set -e` *especially* when working in an module/python environment that takes an age to manually set up.

In today's guffs, I just noticed I submitted an abstract with the title "Dr" thinking it was asking for *my* title.

[Jamie Quinn @jimjonquinn]

@JohnsenSCFPL Congratulations @ Dr. An! Are those rather pretty images available online anywhere?

[Jamie Quinn @jimjonquinn]

Great reference for

1. sets of different governing equations (including a few niche ones) and

2. exact solutions to *many* of those equations

To those interested, please remember that the latest version of "I do like CFD, VOL.1" is always available at the official website https://t.co/9e1roGci31 . You might find a pdf somewhere else, but it's usually an older version.

[Jamie Quinn @jimjonquinn]

@costa_p NICE. What changed?

[Jamie Quinn @jimjonquinn]

People who remember to take old lanyards to conferences have their lives together in ways I will always respect

@HiroNishikawa There have been a *few* cases developing spectral codes where I've only needed a linear solver in 1 dimension, so something like the Thomas alg for tridiagonal systems can give better performance. It's a rare situation though.

Today's HPC flex - replaced 50,000 lines of automatically generated C++ code with ~300 for a single-core speedup of 63%.

Ryanair are awful for many reasons but the one that fucks me off the most is the lack of wee pockets at the back of seats. Where am I meant to put all my books I won't read?

@HiroNishikawa `const` in C is another keyword that helps indicate intent. `void f(const float *u)` ensures u will not be modified inside f, equivalent to `intent(in)`.
