Unfortunately Sony didn’t release its first floppy disk camera as a product, it was made as a prototype only in 1981.

This week's Torah reading is the first of several that detail the construction of the Mishkan, the portable temple that the Jewish people took with us on our journeys through the desert. Even the most mundane technicalities of construction are reviewed thoroughly. This is still important for us to study although we will never build another Mishkan, because it teaches us about the nature of having a relationship with the divine, and bringing holiness and meaning into our lives. It isn'…

Eruption of a million-Kelvin warm magnetic flux rope on the Sun
Solar magnetic flux rope (MFR) plays a central role in the physics of coronal mass ejections (CMEs). It mainly includes a cold filament at typical chromospheric temperatures (10000 K) and a hot channel at high coronal temperatures (10 MK). The warm MFR at quiescent coronal temperatures of a million Kelvin is, however, rarely reported. In this study, using multiwavelength images from Atmospheric Imaging Assembly (AIA) on board the Solar Dynamic Observatory (SDO) and Extreme Ultraviolet Imager (E…

Alya towards Exascale: Optimal OpenACC Performance of the Navier-Stokes Finite Element Assembly on GPUs
This paper addresses the challenge of providing portable and highly efficient code structures for CPU and GPU architectures. We choose the assembly of the right-hand term in the incompressible flow module of the High-Performance Computational Mechanics code Alya, which is one of the two CFD codes in the Unified European Benchmark Suite. Starting from an efficient CPU-code and a related OpenACC-port for GPUs we successively investigate performance potentials arising from code specialization, alg…

Lots to do yet but the new Kitten¹ settings section (that’s common to all Kitten apps / Small Web places) is coming along nicely. (With the general style/layout borrowed from Domain².)
(It’s currently a single page and I’m breaking it up into multiple ones because it’s time.)
Once I’m done with this I should really record a screencast of Kitten’s new backup and restore feature/data portability.

From Pro, Anti to Informative and Hesitant: An Infoveillance study of COVID-19 vaccines and vaccination discourse on Twitter
COVID-19 pandemic has brought unprecedented challenges to the world, and vaccination has been a key strategy to combat the disease. Since Twitter is one of the most widely used public microblogging platforms, researchers have analysed COVID-19 vaccines and vaccination Twitter discourse to explore the conversational dynamics around the topic. While contributing to the crisis informatics literature, we curate a large-scale geotagged Twitter dataset, GeoCovaxTweets Extended, and explore the discou…

Updates on the Low-Level Abstraction of Memory Access
Choosing the best memory layout for each hardware architecture is increasingly important as more and more programs become memory bound. For portable codes that run across heterogeneous hardware architectures, the choice of the memory layout for data structures is ideally decoupled from the rest of a program. The low-level abstraction of memory access (LLAMA) is a C++ library that provides a zero-runtime-overhead abstraction layer, underneath which memory mappings can be freely exchanged to cust…
