It’s that time of year so watching the best #Christmas movie of all time with Alan Rickman in his best movie performance!
Alt text: A scene from the movie Die Hard, bathed in blue lighting. Alan Rickman, dressed in a dark suit and tie, stands in the foreground holding an open notebook. His face bears a serious expression, characteristic of his role as Hans Gruber. Another figure can be partially seen in the background, slightly out of focus. The lighting and color grading gives the scene a moody, dramatic atmosphere.

JSK @imjsk27 Follow In the last 5 years Kohli has scored 3x 100 ...these 100s came when he came to bat at 187/2 153/2 275/2 Excluding these 3x 10 his numbers in last 5 years Innings - 62 Runs - 1557 Avg - 25.95 50s - 9 Overall numbers 1964 runs @ 31.67 in 65 innings 5 years with 31 avg is pathetic 21:51 • 12/15/24 • 22K Views

Interesting study about the connections between #learning and writing by hand.

“Handwriting but not typewriting leads to widespread brain connectivity: a high-density EEG study with implications for the classroom”

Handwriting but not typewriting leads to widespread brain connectivity: a high-density EEG study with implications for the classroom FR (Ruud) Van der Weel 1, Audrey L H Van der Meer 1,* • Author information • Article notes • Copyright and License information PMCID: PMC10853352 PMID: 38343894 Abstract As traditional handwriting is progressively being replaced by digital devices, it is essential to investigate the implications for the human brain. Brain electrical activity was recorded in 36 university students as they were handwriting visually presented words using a digital pen and typewriting the words on a keyboard. Connectivity analyses were performed on EEG data recorded with a 256-channel sensor array. When writing by hand, brain connectivity patterns Image shows a writing and typing sample with an arrow to a subject wearing an EEG cap with an arrow go EEG recordings to an arrow go the image of a brain and waves go with an arrow to a matrix of “functional connectivity” with and arrow to a image of a brain over a face labeled as “functional network” with an arrow to a graph labeled “network measures”

This is the lens. The entirety of it!
A photo of the Fujifilm XT2 camera with the pocketdispo lens. The camera has a green hand strap and it sat on a brown woolen table. In the background we see some black and white photos on the wall. The pocket dispo lens held against the wooden table and the fujifilm camera lies on its back (without lens).

“Last Leaf”

Bought this new lens called #PocketDispo (see next tweet for picture) that makes it look like you’re shooting on an old disposable camera.

This image is straight out of camera, a #fujifilm XT2.

A church town in the background (white church building with a copper sulfate colored roof and a cross on top). In the front we see tree branches across the face of the church. Some yellow leaves at the bottom left. One bright yellow leaf hangs alone, in the cente of the image, prominent set in front of the church tower. The sky is blue. We see part of a black metal fence with pointy ends at the bottom in the foreground. The entire image has a dreamy, soft feel to it.

Oh god, we’re about to see a spate of “#security” papers that hack this platform aren’t we? 🤦🏽‍♂️

September 7, 2023 Creating the First Confidential GPUs The team at NVIDIA brings confidentiality and integrity to user code and data for accelerated computing. Gobikrishna Dhanuskodi, Sudeshna Guha, Vidhya Krishnan, Aruna Manjunatha, Rob Nertney, Michael O'Connor, and Phil Rogers Today’s datacenter GPU has a long and storied 3D graphics heritage. In the 1990s, graphics chips for PCs and consoles had fixed pipelines for geometry, rasterization, and pixels using integer and fixed-point arithmetic. In 1999, NVIDIA invented the modern GPU, which put a set of programmable cores at the heart of the chip, enabling rich 3D scene generation with great efficiency. It did not take long for developers and researchers to realize “I could run compute on those parallel cores, and it would be blazing fast.” In 2004, Ian Buck created Brook at Stanford, the first compute library for GPUs, and in 2006, NVIDIA created CUDA, which is the gold standard for accelerated computing on GPUs today.

“The Paths Not Taken”

An attempt at #fineartphotography.

#sibinsglass #photography #blackandwhite
A black and white photo of the naked branches of a tree, lit up in bright sunlight, emanating from the bottom left. The various branches are messed together in a tight interweaving pattern. The background is dark. The top right third of the picture is blank (dark background). My signature (my name with the S replaced by an integral sign) appears on the top right corner. The entire image has a white border all around it.
