Nvidia releases $1,999, 8K-capable GeForce RTX 3090 Ti GPU


Many distributed volunteer Computing projects like GPUGRID.net, Folding@home and Einstein@home use GPUs. I am using two GTX nVidia boards but I cannot afford costlier GPU boards like RTX 3090.But many volunteers spend a lot of money to upgrade their PCs, Windows, Linux or Mac.

Adiós Arecibo Observatory: America's largest radio telescope faces explosive end after over 50 years of service


Areicubo gave data to the BOINC SETI@home project of distributed volunteer computing. Now SETI@home has been hibernated because too many data are yet to be analyzed by the Nebula program by David Anderson, the father of both SETI@home and the BOINC platform which hosts 50 odd other projects, including WorldCommunityGrid by IBM and Rosetta@home by the University of Washington, Seattle, all dedicated to research on Covid-19.Arecibo has given data also to the Einstein@home project to search for binary pulsar systems which could produce gravitational waves. It discovered 26 of them.

Square Kilometre Array signs off on construction plans – UK last holdout before building phase begins


The largest radio telescope today is not Arecibo but FAST, the 500 meters antenna in China.

SUSE taps SAP exec Melissa Di Donato to become open-source biz's first female CEO



I am an OpenSuse user. I am running both Linux Leap 15.0 and Thimblewood, this on a Virtual Machine on a Windows 8.1 PC. The Thimblewood is updated almost daily. Keep up the good work!

After years of listening, we've heard not a single peep out of any aliens, say boffins. You think you can do better? OK, here's 1PB of signals


SETI@home project

I often see the Breakthrough Listen logo on data coming from Green Bamk when I run the SETI@home BOINC project on my PCs. I have't seen any data coming from Parkes. I am running also data from Arecibo, which BL does not use.

SUSE and Microsoft give enterprise Linux an Azure tune-up


Re: At what cost?

I used to run OpenSUSE Leap 42.3 on my two Linux hosts running BOINC. I found an invitation to update one and found I had installed Tumbleweed, a development version which would not run BOINC. I went back on the other box and found that the new stable version was Leap 15.0. I installed it on my HP laptop and BOINC works. Any relationship to SLES 15.0?

Arecibo spared the axe: Iconic observatory vital to science lives on


Arecibo has been giving data to the BOINC project SETI@home, with one million users, of which 300000 are active. It has been joined by the 100 meters Green Bank radio telescope in West Virginia under the sponsorship of Breakthrough Listen funded by Yuri Milner, and shall be joined by the Parkes Radiotelescope in Australia.Long live Arecibo!

Good luck building a VR PC: Ethereum miners are buying all the GPUs


I am using two GPU boards, a nVidia GTX 1050 Ti and a nVidia GTX 750 Ti to run 2 BOINC projects, SETI@home and Einstein@home. The speedup is impressive over CPUs and I get many more credits for the same running time. People use up to 8 GPU boards on the same PC.

Nine of the world’s fastest GPU supercomputers


BOINC programs

I am using nVidia GPU boards, a GTX 1050 Ti on a Windows host and a GTX 750 Ti on a Linux host to process SETI@home and Einstein@home tasks both on CPUs and GPUs. The speed difference between a CPU processed task and a GPU processed task si simply amazing.

81's 99 in 17: Still a lotta love for the TI‑99/4A – TI's forgotten classic


Wings for the mind

The TI99/4A had been chosen by the Istituto Tecnologie Didattiche del National Research Council to introduce primary school children to programming in BASIC and especially LOGO. An Italian version of TI LOGO was created by Giovanni Lariccia with its Manual. Mondadori Publishing House printed an Italian version of Horacio C.Reggini "Alas para la mente" and "Artificial Intelligence An Introductory course" by the University of Edinburgh Press.Franco Muzzio Editore . published "A scuola con il Texas Instruments TI99/4A" by Sergio Borsani. Then Texas Instruments retired the machine and the whole project, presented by Milan State University professor Gianni degli Antoni, fell flat.

I have used the TI99/4A to introduce my kids, male and female, to programming but they used it mostly to play games, some of which I still have. I used it to simulate a moon landing.
