Mirantis Offers Lower Cost Open Source Alternative to VMware with Latest Mirantis OpenStack for Kubernetes
After the mess of the acquuisition of VMware people are trying to find substitutes. This article is asserting that Mirantis has a replacement, but it’s OpenStack, yes it could replace it but it’s a quite different king of fish. At the moment I only see Proxmox as substitute.
Kubernetes The Hardware Way
This time is about a guide from Talos regarding how to install it on bare metal. This is a brand new repo.

Pure’s Portworx product gets nod from GigaOm for Kubernetes data storage
The GigaOm Radar for Kubernetes Data Storage highlights Pure Storage’s Portworx as a leading solution for Kubernetes-orchestrated container apps, recognized for its innovation and comprehensive data management capabilities. Portworx is rated highly for its enterprise-grade features and deployment flexibility, outperforming other vendors like IBM’s Red Hat and LINBIT. Conversely, Linstor by LINBIT, a free open-source solution, also ranks well, especially in efficiency and manageability. While Portworx is a paid product, Linstor offers a cost-effective alternative with robust Kubernetes-native storage features.

Linux 6.11 Brings A Dedicated Bucket Allocator For Better Security
The Linux 6.11 kernel will feature a new dedicated bucket allocator designed to improve the efficiency of memory allocation, particularly for small objects. Traditional slab allocators, which are used to manage memory in the kernel, allocate memory in chunks called slabs. Each slab contains multiple objects of the same size, reducing fragmentation and improving cache utilization. However, slab allocators can still suffer from inefficiency when handling many small allocations.
The dedicated bucket allocator in Linux 6.11 addresses these issues by providing a more streamlined and efficient method for allocating and managing small memory chunks. This enhancement is expected to boost overall system performance, reduce memory wastage, and improve the reliability of the Linux kernel's memory management processes. This change represents part of the continuous improvements aimed at optimizing the Linux kernel for better resource management and performance​ (Spinics)​. A slab allocator is a memory management mechanism in the Linux kernel used to efficiently allocate memory for objects of the same size. It works by grouping objects into caches, known as slabs, each containing multiple instances of an object type. This method minimizes fragmentation and overhead, speeds up memory allocation and deallocation, and improves cache utilization by keeping similar objects together. Slab allocators are particularly useful in scenarios where there are frequent allocations and deallocations of objects of the same size, ensuring that memory is managed effectively and efficiently.
