27 Revolutionary Denim Innovations You Need to Know
Circa 2018
This blog post is sponsored by Bluezone, the independent trade show for the denim and sportswear community by Munich Fabric Start. Register for the show here!
We denimheads tend to be a bit nostalgic. That’s one of the reasons we love denim: it’s a constant in the fast-moving world of fashion, something that doesn’t change from one season to the next.
How an Ancient Babylonian Map of Jupiter Helped Rewrite History
Most ancient astronomers have used tables and graphs that describe celestial bodies’ relative positions, depending on the time of year. The idea of describing the motion of planets in the form of a geometric line with the area under the curve equal to the distance traveled by a celestial body is truly innovative. This is essentially an idea that led to integral calculus.
The researcher of the five tablets knew that four of them involved astronomical calculations, but he wasn’t sure until he got a picture of the fifth. After reading them, it became clear that they contained instructions for predicting the motion of Jupiter using the geometric principle by constructing a trapezoidal figure. The finished “product” of their studies is what we now call the Babylonian Map of Jupiter.
The inscriptions on the five tablets show that the Babylonian astronomers measured the estimated daily speed of Jupiter, taking into account the position of the planet on different days. They then used speed and time to calculate the distance they would travel over a period of time, i.e., their calculations are equivalent to the geometric dependence of velocity on time and distance.
Beating hackers at bug hunting
An innovative new collaboration between EPFL’s HexHive Laboratory and Oracle has developed automated, far-reaching technology in the ongoing battle between IT security managers and attackers, hoping to find bugs before the hackers do.
On the 9th of December 2021 the world of IT security went into a state of shock. Before its developers even knew it, the log4j application—part of the Apache suite used on most web servers—was being exploited by hackers, allowing them to take control of servers and data centers all over the world.
The Wall Street Journal reported news that nobody wanted to hear: “U.S. officials say hundreds of millions of devices are at risk. Hackers could use the bug to steal data, install malware or take control.”

Security vulnerabilities revealed in fingerprint sensors and crypto wallets
Security experts from paluno, the Ruhr Institute for Software Technology at the University of Duisburg-Essen (UDE) have developed a new technique that, for the first time, enables fuzz testing of protected memory areas in modern processors. Their method revealed many vulnerabilities in security-critical software.
Intel’s “Software Guard Extension” (SGX) is a widely used technology to protect sensitive data from misuse. It helps developers in shielding a certain memory area from the rest of a computer. A password manager, for example, can be executed safely in such an enclave, even if the rest of the system is corrupted by malware.
However, it is not uncommon for errors to creep in during the programming of the enclaves. Already in 2020, the paluno team from Prof. Dr. Lucas Davi discovered and published several vulnerabilities in SGX enclaves. Now, together with partners form the CASA cluster of excellence, the researchers have achieved another breakthrough in the analysis techniques: Their latest development enables the fuzz testing of enclaves, which is much more effective than the previously used symbolic execution. The idea behind fuzz testing is to feed a large number of inputs into a program in order to gain insights into the structure of the code.
Scientists create ‘artificial intelligence baby’
Scientists have created an artificial intelligence that is able to think and learn like a baby.
The system is able to grasp the basic common sense rules of the world in the same way as humans can, the researchers who create it say.
The breakthrough could not only help advance AI research but also the ways we understand the human mind, scientists say.
