Open-source communities fight over telco market – TechCrunch

Published

on

When you think of MWC Barcelona, chances are you’re thinking about the newest smartphones and other mobile gadgets, but that’s only half the story. Actually, it’s probably far less than half the story because the majority of the business that’s done at MWC is enterprise telco business. Not too long ago, that business was all about selling expensive proprietary hardware. Today, it’s about moving all of that into software — and a lot of that software is open source.

It’s maybe no surprise then that this year, the Linux Foundation (LF) has its own booth at MWC. It’s not massive, but it’s big enough to have its own meeting space. The booth is shared by the three LF projects: the Cloud Native Computing Foundation (CNCF), Hyperleger and Linux Foundation Networking, the home of many of the foundational projects like ONAP and the Open Platform for NFV (OPNFV) that power many a modern network. And with the advent of 5G, there’s a lot of new market share to grab here.

To discuss the CNCF’s role at the event, I sat down with Dan Kohn, the executive director of the CNCF.

At MWC, the CNCF launched its testbed for comparing the performance of virtual network functions on OpenStack and what the CNCF calls cloud-native network functions, using Kubernetes (with the help of bare-metal host Packet). The project’s results — at least so far — show that the cloud-native container-based stack can handle far more network functions per second than the competing OpenStack code.

“The message that we are sending is that Kubernetes as a universal platform that runs on top of bare metal or any cloud, most of your virtual network functions can be ported over to cloud-native network functions,” Kohn said. “All of your operating support system, all of your business support system software can also run on Kubernetes on the same cluster.”

OpenStack, in case you are not familiar with it, is another massive open-source project that helps enterprises manage their own data center software infrastructure. One of OpenStack’s biggest markets has long been the telco industry. There has always been a bit of friction between the two foundations, especially now that the OpenStack Foundation has opened up its organizations to projects that aren’t directly related to the core OpenStack projects.

I asked Kohn if he is explicitly positioning the CNCF/Kubernetes stack as an OpenStack competitor. “Yes, our view is that people should be running Kubernetes on bare metal and that there’s no need for a middle layer,” he said — and that’s something the CNCF has never stated quite as explicitly before but that was always playing in the background. He also acknowledged that some of this friction stems from the fact that the CNCF and the OpenStack foundation now compete for projects.

OpenStack Foundation, unsurprisingly, doesn’t agree. “Pitting Kubernetes against OpenStack is extremely counterproductive and ignores the fact that OpenStack is already powering 5G networks, in many cases in combination with Kubernetes,” OpenStack COO Mark Collier told me. “It also reflects a lack of understanding about what OpenStack actually does, by suggesting that it’s simply a virtual machine orchestrator. That description is several years out of date. Moving away from VMs, which makes sense for many workloads, does not mean moving away from OpenStack, which manages bare metal, networking and authentication in these environments through the Ironic, Neutron and Keystone services.”

Similarly, ex-OpenStack Foundation board member (and Mirantis co-founder) Boris Renski told me that “just because containers can replace VMs, this doesn’t mean that Kubernetes replaces OpenStack. Kubernetes’ fundamental design assumes that something else is there that abstracts away low-level infrastructure, and is meant to be an application-aware container scheduler. OpenStack, on the other hand, is specifically designed to abstract away low-level infrastructure constructs like bare metal, storage, etc.”

This overall theme continued with Kohn and the CNCF taking a swipe at Kata Containers, the first project the OpenStack Foundation took on after it opened itself up to other projects. Kata Containers promises to offer a combination of the flexibility of containers with the additional security of traditional virtual machines.

“We’ve got this FUD out there around Kata and saying: telco’s will need to use Kata, a) because of the noisy neighbor problem and b) because of the security,” said Kohn. “First of all, that’s FUD and second, micro-VMs are a really interesting space.”

He believes it’s an interesting space for situations where you are running third-party code (think AWS Lambda running Firecracker) — but telcos don’t typically run that kind of code. He also argues that Kubernetes handles noisy neighbors just fine because you can constrain how many resources each container gets.

It seems both organizations have a fair argument here. On the one hand, Kubernetes may be able to handle some use cases better and provide higher throughput than OpenStack. On the other hand, OpenStack handles plenty of other use cases, too, and this is a very specific use case. What’s clear, though, is that there’s quite a bit of friction here, which is a shame.

Today’s Wordle Answer #594 – February 3, 2023 Solution And Hints

Published

on

If the answer is still a mystery, the word is “tasty.” Apart from describing food as having agreeable flavor, you could say something or someone is tasty if they’re elegant or tasteful. The word is a diminutive of the root noun “taste,” which is from Old French “tast,” which is the term for the sense of touch (now Modern French tât).

In the original context of its usage around the 1400s, “taste” meant a share or a small portion; or the sense by which the flavor of a thing is discerned; and savor or flavor. But by the late 1600s, it had also taken on the sense of “aesthetic judgment,” or “the ability to recognize and appreciate excellence” (via Etymonline). There are more variations of its usage, however, especially in idioms. For example, if you have a taste for something, it means you have a strong preference or desire for it, and if something’s so bad you can taste it, it means that thing is extremely unpleasant (via The Free Dictionary).

This is all based on the fact that the sense of taste is quite adept at perception and discrimination of refinement or finesse. This is the sense on which phrases like “have a good eye/nose” are also based. On average, the human tongue has 2,000–8,000 taste buds, with hundreds of thousands of receptor cells. To keep the sense of taste as keen as possible, each taste bud gets replaced about every two weeks (via Britannica).

We hope you finish your puzzle before you run out of guesses, and if you have a taste for puzzles, here are more like Wordle to keep you busy.

A New Cybertruck Spotting Just Revealed Two Big Design Changes

Published

on

The first clear change to the Cybertruck has to do with the rearview mirrors. As Electrek correctly notes, the Cybertruck was originally meant to lack side mirrors, favoring the more futuristic solution of body-mounted cameras. Assuming the particular prototype that was spotted on the road in Palo Alto represents recent changes, that’s at least one concession to reality from the aggressively conceptual Tesla truck.

The second, arguably more significant change is to the truck bed. Prior to this sighting, the Cybertruck had yet to be shown with a working, retractable tonneau cover. User Flavio Tronz on Instagram seems to have caught the Cybertruck with the cover half-retracted, suggesting that particular challenge has also been conquered.

In short, the Cybertruck seems to be getting the tweaks and flourishes to be expected for a car that is expected to enter full-scale production soon. The implementation of simple, proven solutions, like side mirrors, suggests that Tesla is getting real about putting their vision of the future on actual roads.

Is It Safe To Charge Your iPhone With Macbook Charger?

Published

on

According to Apple, if you own a Mac laptop or an iPad and have immediate access to the USB power adapter that came with it, you can certainly use it to charge your iPhone without the worry of potentially damaging your mobile device’s battery. It can also be used to charge other Apple products like a pair of AirPods or the Apple Watch. The following Apple USB power adapters are some of the options that can be used to charge your iPhone, provided that you have a USB-to-lightning cable:

  • 5W USB power adapter that came with iPhones that preceded the iPhone 11
  • 10W US power adapter that was included with every iPad Air and iPad Air 2, iPad 2, and iPad mini 2,3, and 4
  • 12W USB power adapter that was packaged with several versions of the iPad Pro

If you have a Mac USB-C power adapter or other third-party adapters that fulfill Apple’s safety standards, they can be used to charge your iPhone as well. Certain USB-C power adapters, when used in tandem with Apple’s USB-to-lightning cable, have the ability to fast-charge an iPhone 8 and later iterations up to 50% battery in about half an hour (via Apple). This includes the 29W USB-C power adapter that accompanied older MacBook models that were released in 2015 onwards as well as the 30W, 35W, 61W, 67W, 87W, 96W, and 140W USB-C power adapters that came with certain versions of the MacBook Air and MacBook Pro. If you own a MacBook laptop and have its Apple-brand power adapter, you should be able to see its wattage printed right on the device itself and determine if it can be used to charge your iPhone.
