  • Cryptonose – Cryptocurrency trading tool

    A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Typically it does not exist in physical form (like paper money) and is also typically not issued by a central authority. Instead, there’s decentralized control.

    Cryptocurrencies have not only had an impact on the world’s expectations surrounding money. They’ve also continued to evolve since the first Bitcoin block was mined back in 2009. Since then, thousands of unique cryptocurrencies have appeared.

    Of these, Bitcoin remains the most popular. Some economists, including several Nobel laureates, have characterized it as a speculative bubble. But Bitcoin could be on the verge of adoption by professional investors which would send its price higher.

  • CPU Power Manager – Control And Manage CPU Frequency In Linux

    There are tools, like TLP, Laptop Mode Tools and powertop, helps reduce power consumption and improves overall Laptop battery life on Linux. Another way to reduce power consumption is to limit the frequency of your CPU. While this is something that has always been doable, it generally requires complicated terminal commands, making it inconvenient for the noobs. But fortunately, there’s a gnome extension that helps you easily set and manage your CPU’s frequency - CPU Power Manager. CPU Power Manager uses the intel_pstate frequency scaling driver (supported by almost every Intel CPU) to control and manage CPU frequency in your GNOME desktop.

    Another reason to use this extension is to reduce heating in your system. There are many systems out there which can get uncomfortably hot in normal usage. Limiting your CPU’s frequency could reduce heating. It will also decrease the wear and tear on your CPU and other components.

  • Software-defined vertical industries: transformation through open source

    What do some of the world’s largest, most regulated, complex, centuries-old industries such as banking, telecommunications, and energy have in common with rapid development, bleeding-edge innovative, creative industries such as the motion pictures industry? They’re all dependent on open source software.  That would be a great answer and correct, but it doesn’t tell the whole story. A complete answer is these industries not only depend on open source, but they’re building open source into the fabric of their R&D and development models. They are all dependent on the speed of innovation that collaborating in open source enables. 

More IBM/Red Hat Leftovers

  • Red Hat OpenShift named as most widely deployed multicloud container platform

    US-based enterprise open source software solution provider Red Hat Inc’s Red Hat OpenShift has been named as the most widely deployed multicloud container platform, boosting powerful development and unified operations experiences across many public and on-premises platforms.

  • Ceph scales to 10 billion objects

    Ceph, the open source integrated file, block and object storage software, can support one billion objects. But can it scale to 10 billion objects and deliver good and predictable performance? Yes, according to Russ Fellows and Mohammad Rabin of the Evaluator Group who set up a Ceph cluster lab and, by using a huge metadata cache, scaled from zero to 10 billion 64KB objects. In their soon-to-be published white paper commissioned by Red Hat, “Massively Scalable Cloud Storage for Cloud Native Applications”, they report that setting up Ceph was complex – without actually using that word. “We found that, because of the many Ceph configuration and deployment options, it is important to consult with an experienced Ceph architect prior to deployment.”

  • What I learned as an engineering intern at Red Hat

    Interning at Red Hat has been one of the most challenging summers of my life, but it's been well worth it. Being an engineering intern working on Red Hat OpenShift's GitOps workflow has forced me to grow and learn more than ever before. My internship position on March 4th. A very short time later, COVID-19 caused companies to cancel their internships all over the United States. Thankfully, Red Hat announced that internships would go on in a virtual format.The Early Talent team made the necessary arrangements to make sure that our experience was impacted as little as possible by this change.

  • Start contributing to open source Call for Code projects

    Jumping into the open source world can be intimidating for the uninitiated. Don’t let fear of the unknown stop you from getting involved in open source. In this blog post, we cover some of the basics you need to know before contributing your first line of code. [...] Now that you understand that basic gist of open source, let’s go a little deeper. While some open source projects are small developer tools that help you accomplish a single task, other open source projects are large, complicated pieces of software that have interconnected parts. In these larger projects, different teams or working groups focus on developing specific parts of the technology, collaborating on the technology, peer reviewing and testing the code, and contributing their changes to the core tech.

  • Build Smart on Kubernetes World Tour: Developers’ path to platform freedom

    Without a doubt, Kubernetes is one of hottest open tech projects today and has been so for many years now. The reason for its durable, not-so-secret success? It’s the ability to containerize code, which frees developers from the constraint of writing code for one platform only and instead gives you the freedom of write-once, deploy-anywhere development. And why is this important? Enterprises know that the fastest route to app modernization depends on the ability to develop solutions that protect current tech investments, which likely run across multiple cloud platforms on and off premises. In other words, success depends on your ability to build solutions once and deploy them across multiple hybrid cloud platforms. Yep, containers tech delivers all of that and more. With that baseline, I’m writing to let you know that when it comes to learning Kubernetes, the IBM Developer advocates team has you completely covered with the Build Smart on Kubernetes World Tour. Since we launched the World Tour back in the fall of 2019, the team has delivered literally hundreds of free hands-on workshops globally to teach developers about the power of Kubernetes. It’s all part of the IBM Developer Way, delivering on our sole mission to teach the world’s developers about open tech through hands-on workshops and supporting content such as blog posts, tutorials, and videos. With the recent launch of new content on the Build Smart on Kubernetes World Tour site, it feels like a good time to provide a quick virtual tour of all that the site offers. Visit the updated site to find more than just upcoming tour events, but also self-paced learning options. You can now choose whether you learn at your own pace by viewing recorded content, register for upcoming live events, or, even better, both. I’m going to review each section to show you the details.
