Read an ancient text written on a papyrus scroll without unrolling it
(3) | 533 views | 18/09/2023 | Translate: Brent Seales, professor of computer science at the University of Kentucky, discusses his work, spanning two decades, rescuing ancient texts such as the charred scrolls of ‘Herculaneum.
The world’s ugliest music | Scott Rickard | TEDxMIA Scott Rickard has degrees in Mathematics, Computer Science, and Electrical Engineering from M.I.T. and MA and PhD degrees in Applied and Computational Mathematics from Princeton University. At University College Dublin, he founded the Complex & Adaptive Systems Laboratory, where biologists, geologists, mathematicians, computer scientists, social scientists and economists work on problems which matter to people. He is passionate about mathematics, music and educating the next generation of scientists and mathematicians. - One day, a computer will fit on a desk (1974) Science fiction writer Arthur C. Clarke makes the bold claim that one day computers will allow people to work from home and access their banking records.
- An explanation of Moore’s law, modern computing, and why it’s difficult to make faster chips SciShow explains how SciShow exists -- and everything else that's ever been made or used on a computer -- by exploring how transistors work together in circuits to make all computing possible. Like all kinds of science, it has its limitations, but also awesome possibilities.

- Phase-Functioned Neural Networks for Character Control We present a real-time character control mechanism using a novel neural network architecture called a Phase-Functioned Neural Network. In this network structure, the weights are computed via a cyclic function which uses the phase as an input. Along with the phase, our system takes as input user controls, the previous state of the character, the geometry of the scene, and automatically produces high quality motions that achieve the desired user control. The entire network is trained in an end-to-end fashion on a large dataset composed of locomotion such as walking, running, jumping, and climbing movements fitted into virtual environments. Our system can therefore automatically produce motions where the character adapts to different geometric environments such as walking and running over rough terrain, climbing over large rocks, jumping over obstacles, and crouching under low ceilings. Our network architecture produces higher quality results than time-series autoregressive models such as LSTMs as it deals explicitly with the latent variable of motion relating to the phase. Once trained, our system is also extremely fast and compact, requiring only milliseconds of execution time and a few megabytes of memory, even when trained on gigabytes of motion data. Our work is most appropriate for controlling characters in interactive scenes such as computer games and virtual reality systems.
- 50kbit Core Memory – such as the memory of ancient times Core memory was once the staple of all computers. Thankfully those days are gone. But the history is interesting and involves a run-in with the police and some gin.
- How transistors work Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but there’s one foundational invention that almost everything else relies upon: the transistor. Gokul J. Krishnan describes what a transistor is and how this small device enables all the amazing things computers can do.
- Sketchpad – CAD program in 1963 with a graphical user interface This video is a TV show made about the software Ivan Sutherland developed in his 1963 thesis at MIT's Lincoln Labs, "Sketchpad, A Man-Machine Graphical Communication System", described as one of the most influential computer programs ever written. This work was seminal in Human-Computer Interaction, Graphics and Graphical User Interfaces (GUIs), Computer Aided Design (CAD), and contraint/object-oriented programming. While watching this video, remember that the TX-2 computer (built circa 1958) on which the software ran was built from discrete transistors (not integrated circuits -it was room-sized) and contained just 64K of 36-bit words (~272k bytes).

- Modding. Custom case for computer (Battletech/Mech Warrior style). Continue work on computer case in the style of BattleTech (Mech Warrior). A distinctive feature of the Vulture (Mad Dog) have always been two huge missile launchers – in this video we are going to do... Also add a couple of sensors for temperature control on the Arduino and RGB led backlight. Time work took a lot, but I, as usual, tried to cover scope of work in the most compressed form, so as not to bore You)
- A Christmas Computer Bug, and the Future of Files In 1987, a German student wrote CHRISTMA EXEC - a virus whose basic mechanisms still work if you port them to today's desktop computers. Why haven't we changed in nearly 30 years? And what could we do instead?
- How To Make Rope From Grass Rope is one of the most valuable items to have in the wilderness, and this ancient method of creating it produces very good results. Even today some commercially made ropes are wound with the same process. Other natural fibers can be used to create rope (some being much stronger than grass), and this method will work equally as well with any other flexible material. Grass does tend to become brittle when dry which could weaken this rope, but even then it does maintain some strength. In moderate humidity weakness from drying should not become an issue at all. Note that for best results, each of the two tails of the rope should be twisted an equal number of turns as they're wound. That will ensure that the two coils wind around one another tightly and in a double helix pattern. If one side is twisted less than the other it will tend to stay straight, while the more twisted side coils around it like a spring. When I first started winding the rope in the video you can see I didn't do a very good job twisting both strands evenly for the first few inches, and one side was coiled more than the other. Try to avoid that, as it will be a weak point.
