Niels Bohr Theory and its famous quotes
Here i try to conveying the niels bohr life journey and his theory work with great scientist, and his famous quotation
Hiroshima and nagasaki
1. Germany was forced to accept blame and pay reparations for World War 1 and was limited in its military capabilities.
2. Japan had been waging war in Asia in the 1930s and signed a pact with Germany and Italy in 1940.
3. On December 7, 1941 Japan launched a surprise attack on the U.S. naval base at Pearl Harbor, bringing the U.S. into World War 2.
Causes
The United States developed the atomic bomb during World War II and used it against Japan in 1945 to force their surrender and end the war. While Germany had also tried to develop an atomic bomb, the U.S. completed theirs first and dropped bombs on Hiroshima and Nagasaki after Japan refused multiple surrender demands. The bombings succeeded in defeating Japan and marked the conclusion of World War II.
H bomb & brinkmanship
The United States developed the hydrogen bomb in 1952 in response to the Soviet Union developing the atomic bomb in 1949. The US detonated the first hydrogen bomb in the South Pacific in November 1952, destroying an entire island. While the US initially led in hydrogen bomb technology, the Soviets detonated their own hydrogen bomb just one year later. President Eisenhower and Secretary of State Dulles pursued a policy of brinkmanship to contain communism, which included a willingness to use nuclear weapons and a military buildup of air forces and nuclear weapons. This policy led many Americans to fear nuclear attacks and build fallout shelters, initiating several decades of living under the threat of nuclear war.
The atomic bomb (slideshare version)
The atomic bomb was created by the United States during World War II as part of the Manhattan Project. The first atomic bomb test took place in New Mexico in July 1945. On August 6th, the US dropped an atomic bomb called "Little Boy" on Hiroshima, Japan, killing over 70,000 people instantly. Another bomb called "Fat Man" was dropped on Nagasaki 3 days later on August 9th. The atomic bombs caused immense destruction and loss of life in the targeted cities from their nuclear explosions and the aftereffects of radiation exposure.

National Security Agency - NSA mobile device best practices
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
