The new Arduino Ventuno Q is a very different beast. For one, it's powered by the Dragonwing IQ-8275 chipset. This contains an 8-core Kryo CPU (2x Gold Prime at 2.35GHz + 2x Gold at 2.1GHz + 4x Silver at 1.95GHz) and an Adreno 623. The Ventuno Q offers up to 16GB of RAM and up to 64GB of eMMC storage plus an M.2 NVMe Gen 4 connector for SSDs.
Both work with Linux's existing swapping mechanism. Swapping (called paging in Windows) is a way for the kernel to handle running low on available RAM. It chooses pages of memory that aren't in use right now and copies them to disk, then those blocks can be marked as free and reused for something else.
I've had several incarnations of the self-hosted home lab for decades. At one point, I had a small server farm of various machines that were either too old to serve as desktops or that people simply no longer wanted. I'd grab those machines, install Linux on them, and use them for various server purposes. Here are two questions you should ask yourself:
Retail point-of-sale systems today offer a wide range of options for peripherals and hardware. Their technical specifications play a major role in selection, and big retailers often choose multiple vendors to reduce a single point of failure. This gives them an advantage to negotiate price or support as well. Technically, these peripherals also require updating with new models and may have new feature sets. This necessitates the redevelopment of point-of-sale applications, increasing development costs.
With pthread's rwlock (reader-writer lock) implementation, I got 23.4 million reads in five seconds. With read-copy-update (RCU), I had 49.2 million reads, a one hundred ten percent improvement with zero changes to the workload.
Modern Linux is powerful, flexible, stable, and secure. With the exception of some of the more lightweight Linux distributions, it's also far more resource-dependent (just like all modern operating systems). Also: 5 things to consider before leaping from one Linux distribution to another Consider this: The minimum system requirements for Ubuntu Desktop today include just 4GB of RAM. I've run Ubuntu on a virtual machine with only 3GB of RAM.
Kubernetes Horizontal Pod Autoscaler (HPA)'s delayed reactions might impact edge performance, while creating a custom autoscaler could achieve more stable scale-up and scale-down behavior based on domain-specific metrics and multiple signal evaluations. Startup time of pods should be included in the autoscaling logic because reacting only when CPU spiking occurs delays the increase in scale and reduces performance. Safe scale-down policies and a cooldown window are necessary to prevent replica oscillations, especially when high-frequency metric signals are being used.
If you use virtual machines, there's reason to feel less-than-Zen about AMD's CPUs. Computer scientists affiliated with the CISPA Helmholtz Center for Information Security in Germany have found a vulnerability in AMD CPUs that exposes secrets in its secure virtualization environment. The flaw, dubbed StackWarp, potentially allows a malicious insider who controls a host server to access sensitive data within AMD SEV-SNP guests through attacks designed to recover cryptographic private keys, bypass OpenSSH password authentication, and escalate privileges.
The Xeon 600 lineup spans the gamut between 12 and 86 performance cores (no cut-down efficiency cores here), with support for between four and eight channels of DDR5 and 80 to 128 lanes of PCIe 5.0 connectivity. Compared to its aging W-3500-series chips, Intel is claiming a 9 percent uplift in single threaded workloads and up to 61 percent higher performance in multithreaded jobs, thanks in no small part to an additional 22 processor cores this generation.
A few months ago, I decided to breathe new life into a 2019 Dell XPS 15 that had been collecting dust for a couple of years. Despite its (at the time) high-end Core i7 CPU and 32GB of RAM, Windows was frustratingly slow on it. The fan was constantly at full throttle even when the machine was idle, and it regularly failed to install updates.
Windows PCs have faced death threats for decades from a variety of rival devices, including tablets, Macs, Linux computers, and other hardware. But the rise of Ai in recent years could be helping to revive interests in PCs as company's contemplate upgrades in the near future, The first " AI PCs" were introduced amid much fanfare in 2024, and shipments are growing. But enterprises that picked up early AI PCs have been stymied in their embrace of the technology as meaningful offline applications haven't yet materialized.
In the years ahead, AI is going to be a multi-layered fabric that gets woven into every level of computing at the personal layer," Tikoo said. "Our AI PCs and devices will transform how we work, how we play, how we create and how we connect with each other.
In the early days, VAST Data's focus was primarily on storing enormous amounts of data. "Even before we talked about AI, data had to be stored somewhere," Pernsteiner notes. The company started out in the world of HPC (High Performance Computing). The choice of this sector was strategic: in that world, the scale and performance requirements are enormous. With this choice, VAST more or less forced itself to set the bar very high.
At that point, backpressure and load shedding are the only things that retain a system that can still operate. If you have ever been in a Starbucks overwhelmed by mobile orders, you know the feeling. The in-store experience breaks down. You no longer know how many orders are ahead of you. There is no clear line, no reliable wait estimate, and often no real cancellation path unless you escalate and make noise.
My favorite Linux desktop distribution, Linux Mint, is considering slowing down its release cadence. That's because, as lead developer Clement "Clem" Lefebvre explained, while releasing often has worked very well, it produces "these incremental improvements release after release. But it takes a lot of time, and it caps our ambition when it comes to development. ... [so] We're thinking about changing that and adopting a longer development cycle."
The gist of the idea is to run the whole user environment, desktop and all, inside WINE. So it's something like a bare-metal WINE sitting on top of the Linux kernel, with just enough plumbing to connect them up. This is significantly different from the current way, which is to run a completely Linux-based stack - the kernel, an init, a userland, a Linux display system, and a Linux desktop, and then run Windows programs inside that.
