Home Insulation Works: Barriers to Installation (2023) - Doing the right thing is hard, and insurers do not help! #insulation #netZero #futureReady -
Apart from developing a 1st offshore storage site, Denmark awarded subsidies💶 in tenders. Those came with a catch: deliver on time - or face penalties. The winner of the first tender in 2023, Ørsted with two bioenergy🪵🔥 plants, is already struggling with delays.
In the last round, 9 of 10 preselected applicants dropped out, all of them bioenergy🪵🔥 or waste-to-energy🗑️🔥 plants. Did I say 9? Well, 9 announced it, but one mystery🔮 bidder decided to un-drop out. The tender ended with two b…

Abstract: Vector similarity search is an essential primitive in modern AI and ML applications. Most vector databases adopt graph-based approximate nearest neighbor (ANN) search algorithms, such as DiskANN (Subramanya et al., 2019), which have demonstrated state-of-the-art empirical performance. DiskANN's graph construction is governed by a reachability parameter $\alpha$, which gives a trade-off between construction time, query time, and accuracy. However, adaptively tuning this trade-off typically requires rebuilding the index for different $\alpha$ values, which is prohibitive at scale. In this work, we propose RP-Tuning, an efficient post-hoc routine, based on DiskANN's pruning step, to adjust the $\alpha$ parameter without reconstructing the full index. Within the $\alpha$-reachability framework of prior theoretical works (Indyk and Xu, 2023; Gollapudi et al., 2025), we prove that pruning an initially $\alpha$-reachable graph with RP-Tuning preserves worst-case reachability guarantees in general metrics and improved guarantees in Euclidean metrics. Empirically, we show that RP-Tuning accelerates DiskANN tuning on four public datasets by up to $43\times$ with negligible overhead.

„Der „nachhaltige“ Rechtskampf der fünf Freiburger:innen gegen das Verbot sei außerdem als Indiz gewertet worden, dass diese die ursprüngliche Plattform weiterbetreiben wollten und damit Teil des verbotenen Vereins waren.
Das Landgericht sieht auch hier eine „bedenkliche Argumentation“, die Personen von „zulässigem juristischen Vorgehen“ abhalten könne.“

Fantastic! Really happy for you!
I want to leave LinkedIn too.
Leaving Facebook and Twitter was easy as I never relied on them for income. I just left in disgust.
I freelance, and unfortunately a majority of work opportunities comes from people finding me on LinkedIn.
I'm on Xing as well, but in the Nordic…
