Sadly couldn't join myself (wife wasn't feeling good and wanted me to stay home and help parent while she napped) but my SAR team participated in a great inter-agency training this past weekend.
It's always nice to practice alongside volunteers from other teams that we work with on real incidents and get to know each other without the pressure of a real emergency.

Good morning and happy Monday, lovely people of the internet. 🌤☕🥳
Just remember that today is also a new day to look to the future with hope. (Or something like that.)

This is exactly the thing I wonder about. Was it shoved through over internal objections? Was it many teams’ separate good work stuck together too hastily? Was it the wrong kind of pressure from above, or bad taste from below, or what?
It’s frustrating because as a dev I catch glimpses of all the really fantastic engineering work folks at Apple are doing •inside• the box, and they’re feeling very little love for it right now because the •outside•is so clunky.

Abstract: This work extends the front propagation formulation (FPF) combustion model to large eddy simulation (LES) of swirl-stabilized turbulent premixed flames and investigates the effects of resolved flame thickness on the predicted flame dynamics. The FPF method is designed to mitigate the spurious propagation of under-resolved flames while preserving the reaction characteristics of filtered flame fronts. In this study, the model is extended to account for non-adiabatic effects and is coupled with an improved sub-filter flame speed estimation that resolves the inconsistency arising from heat-release effects on local sub-filter turbulence. The performance of the extended FPF method is validated by LES of the TECFLAM swirl-stabilized burner, where the results agree well with experimental measurements. The simulations reveal that the stretching of vortical structures in the outer shear layer leads to the formation of trapped flame pockets, which are identified as the physical mechanism responsible for the secondary temperature peaks observed in the experiment. The prediction of this phenomenon is shown to be strongly dependent on the resolved flame thickness, when the filter size is used for modeling sub-filter flame wrinklings. Without proper modeling of the chemical steepening effects, the thickness of the resolved flame brush is over-predicted, causing the flame consumption rate to be under-estimated. Consequently, the flame brush detaches from the outer shear layer, resulting in a failure to capture the flame pockets and the associated secondary temperature peaks.

OpenAI Names New Infrastructure Leaders Following Stargate Strategy Shift
OpenAI has appointed new leaders to oversee its Stargate computing initiative after deciding to rent more AI servers from major cloud providers rather than build its own data centers, according to two people familiar with the changes. As part of its reorganization, OpenAI has divided its ...
