In this video i will show everyone the Theoretical & Practical side of understanding and learning Reverse-Engineering, to modify Machine-Code/Code overall in the Memory inside Binary Software Files on Systems, and also the Fundamentals about the System Architechture x64/x32-x86 Bit, as how it works in the smallest of Bits/Bytes form on the Memory-Layout Architechture. I will be showing a variety of Techniques like Cracking Games, Manipulating basic “Hello World” compiled C++ code Binary, and overall i will show different kind of Debugging/Reverse-Engineering Techniques on the Tool x64DBG.
- Educational Purposes Only.

If the Video was helpful and useful for learning Reverse-Engineering in a sense to understand Problematic Bugs/Vulnerabilities or Code in a Binary, subscribe for more videos!. Thanks.

Flexible polymers made with a new generation of the Nobel-winning “click chemistry” reaction find use in capacitors and other applications.

Society’s increasing demand for high-voltage electrical technologies – including pulsed power systems, cars, electrified aircraft, and renewable energy applications – requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions.

A new polymer-based device that efficiently handles record amounts of energy while withstanding extreme temperatures and electric fields has now been developed by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Scripps Research. The device is composed of materials synthesized via a next-generation version of the chemical reaction for which three scientists won the 2022 Nobel Prize in Chemistry.

Does our increasing dependency on technology diminish our human potential? In this episode, visionary scientist Gregg Braden discusses the current transhuman movement – the merging of technology and human biology, often referred to as the singularity. He describes three levels of tech integration where the final level replaces our natural biology. In a time of rapid evolution, reflection and discernment are key. Braden highlights what we can do to release the conditioning of a technology-dependent society and how to follow the natural rhythms within ourselves.

The latest advancements in AI for gaming are in the spotlight today at Gamescom, the world’s largest gaming conference, as NVIDIA introduced a host of technologies, starting with DLSS 3.5, the next step forward of its breakthrough AI neural rendering technology.

DLSS 3.5, NVIDIA’s latest innovation in AI-powered graphics is an image quality upgrade incorporated into the fall’s hottest ray-traced titles, from Cyberpunk 2077: Phantom Liberty to Alan Wake 2 to Portal with RTX.

But NVIDIA didn’t stop there. DLSS is coming to more AAA blockbusters; emotion is being added to AI-powered non-playable characters (NPCs); Xbox Game Pass titles are coming to the GeForce NOW cloud-gaming service; and upgrades to GeForce NOW servers are underway.

Various medical circumstances, including heart attacks and extreme cases of COVID-19, necessitate the use of anticoagulants, medicines that prevent blood clots. But the most commonly used, heparin, can induce potentially fatal side effects by making the blood clots worse rather than better. This only happens in a minority of patients so effective treatments are not commonly explored. For the first time, researchers, including those from the University of Tokyo, have proposed a side effect-free anticoagulating treatment that has so far proved effective in test mice and could be ready for human trials in just a few years.

The COVID-19 pandemic brought much woe to people around the world. And at the time of writing, though much of the world seems to have moved on, the effects of the pandemic continue to linger. One aspect of some extreme cases of COVID-19 that has not been widely reported is the complication brought on when the anticoagulant medicine heparin is used in an attempt to reduce blood clots in patients. A small number — up to 3% of recipients — suffer the side effect heparin-induced thrombocytopenia (HIT), a potentially fatal and rapid clotting of the blood, the opposite of the intended effect. Other medical issues, such as heart attacks, kidney dialysis, and even some surgeries, can also require anticoagulants.

The era of mainframe computers and directly programming machines with switches is long past, but plenty of us look back on that era with a certain nostalgia. Getting that close to the hardware and knowing precisely what’s going on is becoming a little bit of a lost art. That’s why [Phil] took it upon himself to build this homage to the mainframe computer of the 70s, which all but disappeared when PCs and microcontrollers took over the scene decades ago.

The machine, known as PlasMa, is not a recreation of any specific computer but instead looks to recreate the feel of computers of this era in a more manageable size. [Phil] built the entire machine from scratch, and it can be programmed directly using toggle switches to input values into registers and memory. Programs can be run or single-stepped, and breakpoints can be set for debugging. The internal workings of the machine, including the program counter, instruction register, accumulator, and work registers, are visible in binary lights. Front panel switches let you control those same items.

The computer also hosts three different microcodes, each providing a unique instruction set. Two are based on computers from Princeton, Toy-A, and Toy-B, used as teaching tools. The third is a more advanced instruction set that allows using things like emulated peripherals, including storage devices. If you want to build one or just follow along as the machine is constructed, programmed, and used, [Phil] has a series of videos demonstrating its functionality, and he’s made everything open-source for those more curious. It’s a great way to get a grasp on the fundamentals of computing, and the only way we could think of to get even more into the inner workings of a machine like this is to build something like a relay computer.

You may have heard of light as both particles and waves, but have you ever imagined the secret dance within? Researchers from the University of Ottawa and Sapienza University in Rome have just uncovered a groundbreaking technique that enables the real-time visualization of the wave function of entangled photons — the fundamental components of light.

Imagine choosing a random shoe from a pair. If it’s a “left” shoe, you immediately know the other shoe you’ve yet to unbox is meant to go on your right foot. This instantaneous information is certain whether the shoe box is within hand’s reach or 4.3 light-years away on some planet in the Alpha Centauri system.

This analogy, though not perfect, captures the essence of quantum entanglement. At its core, quantum entanglement refers to the phenomenon where two or more particles become deeply interconnected in such a way that their properties become correlated, regardless of the spatial separation between them. This means that the state of one particle instantly influences the state of another, even if they are light-years apart.

Elon Musk-owned X, formerly Twitter, is planning to roll out a new way to display news links without any headline or description. The social network will display just the link and the header image in a post, according to a report by Fortune.

Musk confirmed the move in a post on Monday and said it was coming “directly” from him. The change would “greatly improve the aesthetics,” he said.

This is coming from me directly. Will greatly improve the esthetics.
