Unlock the Keys to True Leadership
Unlock the Keys to True LeadershipMichael Mamas A leader must be able to hold much inner strength and private feelings while also walking alone, as a leader's role is solitary despite having many people by their side. True leadership requires an all-out commitment to a noble cause rather than tending only to one's private life, though a leader must know when some inner thoughts cannot be openly communicated.

Manure
ManureMohammed Haque Organic manure prepared from kitchen waste can produce nutritious vegetables while being environmentally friendly. Currently, Bangladesh soil contains less than 1% organic matter due to overuse of chemical fertilizers instead of organic materials like compost and manure. This is decreasing soil fertility and quality of produce while increasing malnutrition and diseases. Setting up organic manure preparation plants to process urban waste could produce millions of tons of organic fertilizer annually to improve soil and nutritional health for plants and people.

Why do I need Kubernetes?
Why do I need Kubernetes?Simone Morellato Containers provide an abstraction layer above the operating system similar to how virtual machines abstract hardware. Containers allow applications to be portable and isolated, using fewer resources than virtual machines. Container orchestration platforms like Docker and Kubernetes are needed to manage containerized applications across multiple hosts for scalability and high availability.
VMs and Containers - Friends or Enemies
VMs and Containers - Friends or EnemiesSimone Morellato This document compares virtual machines (VMs) and containers, explaining how each technology abstracts different levels of the application stack. VMs abstract the operating system from hardware, allowing multiple operating systems to run on the same physical server. Containers further abstract applications from the operating system, enabling multiple applications to run on a single operating system. While VMs provide hardware-level isolation and are battle-tested, containers offer more efficient application packaging and portability. The document concludes that VMs are best for long-running stateful applications due to security and isolation, while containers excel at short-running stateless applications due to agility.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

How did we get to Containers: A brief History of Computing
- 1. Technology Milestones that lead to Applications Portability Simone Morellato, Director of Technical Product Management
- 2. Apcera Confidential Physical Server App First, Application and Hardware were tightly coupled
- 3. Apcera Confidential Physical Server App Virtual Machine Second, Virtualization decoupled the Operating System from the Hardware Abstract the OS from the Hardware
- 4. Apcera Confidential Physical Server Virtual Machine Third, Container Technology decoupled the Application From the Operating System … Abstract the App from the OS App Containers
- 5. Apcera Confidential Any infrastructure … Finally freeing the Application from the underlying Infrastructure App Containers
Editor's Notes
- #3: First, we used to develop applications with specific hardware requirements in mind, making applications and Hardware very tightly coupled together. An app designed for server “A” may not be able to run on server “B”.
- #4: But with the invention of virtualization, we could abstract the Operating System from the Hardware, allowing virtual machines to move between different physical servers, but only if those servers are running the same virtualization software. If your application is running in a VMware VM, you can’t easily move it to an KVM VM, let alone move it to the cloud providers. Moreover, the Application code and the Operating System are still pretty tightly coupled together.
- #5: But with the rise of container technology, pioneered at Google, we are finally able to abstract the Application from the Operating System, A containerized application has all the dependencies, libraries and packages that it needs to enable us to “Build an app once and run it anywhere.”
- #6: Finally freeing the application from the underlying operating systems and hardware infrastructure and allowing applications not only to move to different physical servers also between private or public clouds such us VMware or AWS.
