Micron sets its sights on quad-cell storage

Micron is the latest NAND flash memory maker to announce plans for quadruple-level cell (QLC) flash memory, following similar announcements from Toshiba and Western Digital. It's a very technical story with a very real impact.NAND flash memory stores data in one bit per cell, with billions of cells in the flash memory chips. For flash drives to gain capacity, there are two solutions: increase the number of chips in the drive, which has physical limitations, and increase the density per cell, which is limited by the laws of physics.Also read: Impact of Intel and Micron ending their NAND partnership is negligible | Sign up: Receive daily tech news updates The first single-level cell, with one bit per cell, first emerged in the late 1980s when flash drives first appeared for mainframes. In the late 1990s came multi-level cell (MLC) drives capable of storing two bits per cell. Triple-level cell (TLC) didn't come out until 2013 when Samsung introduced its 840 series of SSDs. So, these advances take a long time, although they are being sped up by a massive increase in R&D dollars in recent years.To read this article in full, please click here

Using Go as a scripting language in Linux

Using Go as a scripting language in Linux

At Cloudflare we like Go. We use it in many in-house software projects as well as parts of bigger pipeline systems. But can we take Go to the next level and use it as a scripting language for our favourite operating system, Linux?

Why consider Go as a scripting language

Short answer: why not? Go is relatively easy to learn, not too verbose and there is a huge ecosystem of libraries which can be reused to avoid writing all the code from scratch. Some other potential advantages it might bring:

  • Go-based build system for your Go project: go build command is mostly suitable for small, self-contained projects. More complex projects usually adopt some build system/set of scripts. Why not have these scripts written in Go then as well?
  • Easy non-privileged package management out of the box: if you want to use a third-party library in your script, you can simply go get it. And because the code will be installed in your GOPATH, getting a third-party library does not require administrative privileges on the system (unlike some other scripting languages). This is especially useful in large Continue reading

Is the IoT backlash finally here?

As pretty much everyone knows, the Internet of Things (IoT) hype has been going strong for a few years now. I’ve done my part, no doubt, covering the technology extensively for the past 9 months. As vendors and users all scramble to cash in, it often seems like nothing can stop the rise IoT.Maybe not, but there have been rumblings of a backlash to the rise of IoT for several years. Consumer and experts worry that the IoT may not easily fulfill its heavily hyped promise, or that it will turn out to be more cumbersome than anticipated, allow serious security issues, and compromise our privacy.To read this article in full, please click here

Automation: Easy Button vs Sentient Voodoo Magic Button

Automation has become this “all-encompassing thingy” much like SDN. It’s a software industry problem and it’s critical more now than ever that we do not slip backwards by trying to drag a broken idea forwards.

This post contains nothing new and should act as polish on common sense. If you’re on the look-out for removing pain and getting stuff done with the power of automation, read on.

If your processes and operating handbook for your team or organisation is in disarray, it will not come too much as a surprise when your automation team implements something inherently broken. Naturally the technology, shortly followed by the team will take a boat load of blame. Whilst artificial intelligence and machine learning is promising, unless you have a team of subject matter experts or have very deep pockets, automation today is simple and the patterns are hard wired. Even decision making logic has been should be pre-thought. Automation platforms do not today think creatively and do not possess sentient capabilities. If they did, I would be on a beach right now drinking mojitos, smoking cigars and wondering what to do with my time on this rock (the answer by the way would be Continue reading

On the ‘net: Spectre, Meltdown, and Flexible Scaleout

The recent Meltdown and Spectre attacks illustrate the problematic nature of modern computing systems. While the earlier Rowhammer attack could read or attack one process running in a virtual environment from another process running on the same processor, the Meltdown and Spectre attacks are of a completely different class, enabling a process to read large amounts of information from another process’ memory space. @GestaltIT

Context-Aware Micro-segmentation – Remote Desktop Session Host Enhancements for Citrix

In a previous post by my colleague, Stijn, discussed the new changes to how NSX for vSphere 6.4 handles Remote Desktop Session Host, RDSH, systems with the Identity-based Firewall and context-aware micro-segmentation.

RDSH is an underlying technology from Microsoft that many vendors take advantage of to provide overlay management and application deployment technologies for.  In this post, we’re going to discuss how NSX 6.4 and the new changes to support RDSH hosts works with Citrix XenApp systems.

Citrix XenApp can provide multiple users the ability to connect to a single system to access their applications using the RDSH technology.  These users can be of the same type, for example all HR users, or of multiple types, HR and Engineering users.  NSX has supported User Identity based firewalling for Virtual Desktops since the 6.0 release, but it did not address RDSH in which multiple user sessions are connecting to the same host  This meant less flexibility in controlling what users could access data center application servers without isolating one set of users to one RDSH server.  This model created a very rigid architecture for XenApp customers to follow, which brought about the use of Continue reading

VMware’s Honore’ LaBourdette Discusses ‘Hybridity’ & the Next Wave of Telco Virtualization

But to truly participate in the cloud economy, compete effectively with OTT rivals, and be positioned to capture the rich opportunities presented by 5G and... Read more →

Video Series: Modernizing .NET Apps for Developers

MTA for Devs

 Docker Enterprise Edition (EE)  is the container platform for modernizing your existing applications, and running them in the cloud or on-premises. You can take monoliths and run them in containers with no code changes, and that gets you portability, security and efficiency.

Running in Docker is also a great starting point for modernizing the application architecture. You can breaking down the monolith into smaller, independent components which makes it easier to deploy updates, manage scale and introduce new technologies.

This new video series covers app modernization, for .NET developers and architects. It walks through the evolution of a monolithic ASP.NET 3.5 app to a distributed application running across multiple containers, using the Docker platform to plug everything together and adding features with great open-source software from the Docker ecosystem.

This is not a full re-architecture to microservices – for large .NET apps that would be a 12 month project. This series uses a feature-driven approach, taking key features out of the monolith to fix performance issues, add new functionality and support fast application updates.

Part 1 introduces the series, talks about what “modernization” means and then gets started – this is a very demo-heavy video series, where you’ll see lots Continue reading
