World’s fastest supercomputer ‘El Capitan’ goes online
The fastest supercomputer in the world has officially launched at the Lawrence Livermore National Laboratory (LNNL) in California.
The supercomputer, called “El Capitan,” cost $600 million to build and will handle various sensitive and classified tasks including securing the U.S. stockpile of nuclear weapons in the absence of underground testing, according to LNNL representatives. This was prohibited in 1992.
Research will primarily be focused on national security, including material discovery, high-energy-density physics, nuclear data and weapon design, as well as other classified tasks.
Construction on the machine began in May 2023, and it came online in November 2024, before being officially dedicated on Jan. 9.
El Capitan became the world’s fastest computer when it became fully operational last year with a score of 1.742 exaFLOPS in the High-Performance Linpack (HPL) benchmark.
This is a test used to judge supercomputing speeds all over the world. This makes El Capitan only the third computer ever to reach exascale computing speeds. It has a peak performance of 2.746 exaFLOPS.
Performance is measured in floating-point operations per second (FLOPS), where one floating-point operation is a mathematical calculation.
Although like-for-like comparisons are tricky, the best laptops usually deliver several hundred gigaFLOPS of power — that’s 1 trillion (10^9) FLOPS. An exaFLOP is 1 quintillion (10^18) FLOPS.
The next fastest supercomputer in the world is currently the Frontier supercomputer at Oak Ridge National Laboratory in Illinois.
That supercomputer has achieved a standard performance of 1.353 exaFLOPS with a peak of 2.056 exaFLOPS.

Chester Burton "Chet" Atkins, Mister Guitar (1924)June 20, 2026
Atkins got his first guitar by making a trade with his brother, and it was arguably the best deal he ever made. Although he struggled with shyness and suffered from severe asthma—he had to sleep sitting up and often fell asleep still holding his guitar—he became an accomplished guitarist and went on to release several hit records, develop a signature line of guitars, and help create country music's "Nashville sound." What did "Mr. Guitar," as he came to be known, trade to get that first guitar?

West Virginia DayJune 20, 2026
West Virginia Day is a state holiday in West Virginia to celebrate its joining the Union in 1863 as the 35th state. The creation of the state was a result of the Civil War. The settlers of western Virginia defied the state's vote to secede from the Union, and on June 20 West Virginia formally entered the Union as an anti-slave state. The day is marked with ceremonies at the state capitol in Charleston and at the West Virginia Independence Hall in Wheeling. It was there that the conventions were held to declare West Virginia's independence from Virginia.

Black TeaJune 20, 2026
Excluding water, tea is the most widely consumed drink on the planet, drunk either hot or cold by half the world's population. The vast majority of tea sold in the West is black tea, made from fermented leaves of the Camellia sinensis plant. Generally stronger in flavor and more caffeinated than the green and oolong varieties, black tea retains its flavor for several years and has long been an article of trade, serving as a form of currency into the 19th century in what countries?
