I'm a huge believer in having a hobby that forces you to focus on one thing. This summer I'm learning how to draw and paint wildflowers. It's absorbing and relaxing and even if the results are a bit rough, it forces you to really *look* at small details.

reinderdijkhuis@mastodon.art - It's @ajroach42 's recent threads about addictive behavior in (mostly) kids (but he talks about adults and elders as well) that prompted me to evaluate my own online behavior, again. The line "… they'd rather do nothing, when doing nothing is causing them a great amount of distress, than have to put the work in to do something else" hit hard. More and more these past few months, that's been me, unless I make a very deliberate effort not to go down that path.

Combating Reentrancy Bugs on Sharded Blockchains
Reentrancy is a well-known source of smart contract bugs on Ethereum, leading e.g. to double-spending vulnerabilities in DeFi applications. But less is known about this problem in other blockchains, which can have significantly different execution models. Sharded blockchains in particular generally use an asynchronous messaging model that differs substantially from the synchronous and transactional model of Ethereum. We study the features of this model and its effect on reentrancy bugs on three…

Lumina: Real-Time Mobile Neural Rendering by Exploiting Computational Redundancy
3D Gaussian Splatting (3DGS) has vastly advanced the pace of neural rendering, but it remains computationally demanding on today's mobile SoCs. To address this challenge, we propose Lumina, a hardware-algorithm co-designed system, which integrates two principal optimizations: a novel algorithm, S^2, and a radiance caching mechanism, RC, to improve the efficiency of neural rendering. S2 algorithm exploits temporal coherence in rendering to reduce the computational overhead, while RC leverages th…

teaching a transformer net to approximate ray-tracing
input is a sequence of triangle data (limited to 4k triangles), and a sequence of 8x8 radiance pixels representing the camera (limited to 512x512 resolution)
output is a sequence of 8x8 pixels of the rendered scene. training was ~10 days. generation is ~100ms (NVIDIA A100)
the results are pretty good. scaling will be a challenge (since transformers are quadratic in sequence length)

A3FR: Agile 3D Gaussian Splatting with Incremental Gaze Tracked Foveated Rendering in Virtual Reality
Virtual reality (VR) significantly transforms immersive digital interfaces, greatly enhancing education, professional practices, and entertainment by increasing user engagement and opening up new possibilities in various industries. Among its numerous applications, image rendering is crucial. Nevertheless, rendering methodologies like 3D Gaussian Splatting impose high computational demands, driven predominantly by user expectations for superior visual quality. This results in notable processing…

Danke, die Reaktionen haben das schon mal in Perspektive gesetzt und ich bin wirklich ganz am unteren Ende von "wie schlimm kann es sein".
Also schicke ich wohl den Gatten Tape kaufen und bleibe ansonsten nur erst mal vom Fahrrad runter. Denn das ist mein Abstell-Fuß.

Former Raiders' 1st-Rounder Works Out For AFC Foe https://www.si.com/nfl/raiders/las-vegas-houston-texans-damon-arnette-demeco-ryans

Großer Moment meiner Kindheit: im „größten“ Kaufhaus der Kreisstadt Rolltreppe fahren. Es gab dort genau eine Rolltreppe, vom Erdgeschoß in den ersten Stock. Die Spielwarenabteilung war oben. Es war zugleich die erste und im weiteren Umkreis lange die einzige Rolltreppe. Runter musste man zu Fuß gehen. Wir sind in den späten 1970ern, Südostbayern.

Man kann ja echt nur noch mit dem Kopf schütteln, in unseren Medien wird diese Krawalle in LA runtergespielt und tun so, als hätten die Demostranten auch noch schuld an der ganzen Lage.
Wann zum Henker wird mal einer Klartext reden und den scheiss Donald Frontal angreifen ?
Donald droht sogar einen Gouverneur verhaften zulassen #wtf
Wie weit darf dieser Kerl eigentlich noch gehen.
