OpenStack Stein: A new cool drink of open-source cloud

Published

on

The future of cloud-based services
Jason McGee, IBM fellow, VP and CTO, IBM cloud platform, talks about how IBM continues to grow within the open-source community.

While OpenStack is concerned with more than just Infrastructure-as-a-Service (IaaS) cloud these days, it’s still primarily an open-source cloud open-source consortium. In its latest release, OpenStack Stein, the cloud comes with significant network management, bare metal, and containers improvements.

For its users, which include many telecoms, the network management part is the most tasty part. OpenStack Neutron, its networking-as-a-service component, now boasts Network Segment Range Management. This enables cloud administrators to manage network segment type ranges dynamically. It uses a new application programming interface (API) extension to do this. Previously, you were stuck with manually editing configuration files.

Neutron also now treats treats bandwidth as a resource. Thus, it can work with the OpenStack Nova compute service to schedule instances only to hosts, which have enough bandwidth to do a given job effectively.

Finally, other Neutron API improvements support for Quality of Service (QoS) policy rule aliases. This enables sysadmins to to delete, show, and update QoS rules much more easily.

Ironic, OpenStack’s bare-metal provisioning service, offers better deployment templates. Standalone users can now request allocations of bare-metal nodes with submitted configuration data. Previously, you had to use pre-formed configuration drives.

As for Kubernetes — because who isn’t using Kubernetes for container orchestration? — OpenStack Magnum has greatly improved Kubernetes cluster launch time. With Stein, it will only take you five minutes per node instead of 10 to 12 minutes. With this release, too, you can now launch a fully integrated Kubernetes cluster with support for such core OpenStack services as Manila, Cinder, and Keystone on a pre-existing OpenStack cloud.

OpenStack is also adding some new services. These include:  

  • Blazar, the resource reservation service, introduced a new Resource Allocation API allowing operators to query the reserved state of their cloud resources.
  • Placement enables you to target a candidate resource provider. This makes it easier to specify a workload migration host. In turn, this increases API performance by 50 percent for common scheduling operations. Nova’s internal Placement service will be removed by the the Train release scheduled for October 2019.
  • Sahara, makes it easier to provision data processing frameworks, such as Apache Hadoop, Apache Spark, and Apache Storm, on OpenStack. It’s been been refactored into a easier-to-use architecture to make it easier to use this functionality.

Jonathan Bryce, the OpenStack Foundation executive director, summed this release up: “With Stein, operators gain new capabilities for bare metal management and networking, running high-performance workloads with GPUs, operating and Network functions virtualization (NFV) deployments. OpenStack has also become a powerful platform for managing Kubernetes clusters in private and multi-cloud deployments.”

How To Build Your Own Retro Gaming Console With A Raspberry Pi

Published

on

Once your micro SD card is mounted with RetroPie, you can plug it into your fully assembled Raspberry Pi 4 and begin the setup process in the software menu that appears. Make sure your controller is nearby, as you’ll need it during the first boot process. If you’re using a USB controller, make sure it’s connected physically, then follow the instructions on-screen.

If you’re using a Bluetooth controller, tap F4 on your USB keyboard to exit back into the Linux command prompt screen, then type and execute the command “sudo ~/RetroPie-S etup/retropie-setup.sh” that loads you into a backend RetroPie menu. Navigate to the Bluetooth option and then open it to begin searching for a controller. Set your Bluetooth controller to sync mode, then pair it in the menu. Return to the Linux command prompt and type the command “sudo shutdown -r now”. Upon loading back into RetroPie, you should be able to use your Bluetooth controller by simply turning it on and following the on-screen menu. Once everything is complete, you’ll end up on another menu with the option RASPI-CONFIG, which you should now select.

Upon tapping that option, you’ll be taken to the main configuration menu for RetroPie, which includes all sorts of different settings. Go ahead and configure whichever settings you need. It’s also a good idea to navigate to Advanced Settings and disable Overscan if you’re using an HDTV. From here, you should be able to load your ROMs (stored on your SD card) and play them from the menu that appears when you boot up RetroPie. Check out the RetroPie documentation for troubleshooting any issues you may encounter, and happy gaming!

Today’s Wordle Answer #377 – July 1, 2022 Word Solution And Hints

Published

on

The solution for the July 1, 2022, edition of Wordle is pinto. It made its way to the English vocabulary from the Spanish word pinto, which refers to a subject that is spotted or mottled. Horses with a patchy coloration, especially those rocking white patches, are affectionately known as pinto.

The word traces its etymological roots to the Latin term pinctus, which is used to describe something that has been painted over. The pinto bean, which is a staple in Mexican, Spanish, and Brazilian cuisines, also gets its name from the patchy color profile of its outer skin. According to Ancestry data, Pinto is a popular Catalan name that eventually made its way to the Indian subcontinent with the advent of Portuguese invaders.

Interestingly, it is also used to describe a person with greying hair, something pop culture describes as a salt-and-pepper look. You can trace the history of Pinto family migration across the U.S. and Canada in the 19th century here. As for famous personalities with that surname, the actress described above is Freida Pinto, while the footballer in question is José Manuel Pinto. Meanwhile, Fernão Mendes Pinto was a renowned Portuguese explorer and writer who also has a crater on the planet Mercury named after him.

This New $6 Raspberry Pi Is The Computer The DIY Smart Home Needs

Published

on

In terms of hardware, the Raspberry Pi Pico W is identical to its predecessor; it sports the same RP2040 Arm Cortex M0+ Dual-Core SoC, which is based on TSMC’s 40nm low power manufacturing process. This chip clocks up to 133MHz and also packs in 264KB of SRAM. There is 2MB of onboard flash storage thrown in, as well. Additionally, the machine features a 40-pin GPIO just like the original Pico from 2021. The onboard micro USB controller can be used for data transfer and receiving power.

The Wi-Fi module on the Raspberry Pi Pico is the Infineon CYW43439 wireless that, apart from supporting 2.4GHz Wi-Fi networks, also adds Bluetooth Classic and Bluetooth Low-Energy support. However, as of now, Raspberry has chosen not to enable Bluetooth capability in the machine. The company does not rule out the possibility of enabling Bluetooth further down the line, though.

With over 2 million Raspberry Pi Pico boards in the hands of consumers, the company expects its new model to enjoy similar success. The company also believes that the ongoing chip shortage has been among the prime reasons for the popularity of the RP2040-based Raspberry Pi Pico. The Pico W, thanks to its newfound wireless capability, will continue to be a great product that can power many IoT-based applications and DIY smart home needs. With a price tag of $6, the Raspberry Pi Pico W costs just $2 more than its predecessor. As the ecosystem for starter microcontrollers evolves, the $6 you spend on the Pico W will definitely be a worthwhile investment.
