Apple acquiring most of Intel’s smartphone modem business in $1B deal

After Apple only recently announced to partner with Qualcom on 5G modems, Intel quickly decided to cease their efforts in that area. In that market situation, Apple likely landed a bargain on this deal.

Apple has entered into a deal to acquire a majority of Intel’s modem business, TechCrunch has learned. The deal, valued at around $1 billion, includes Intel IP, equipment, leases and employees, with Apple bringing over 2,200 new roles and bringing its portfolio up 17,000 wireless technology patents. “We’ve worked with Intel for many years and know this team shares Apple’s passion for designing technologies that deliver the world’s best experiences for our users,” Apple SVP Johny Srouji said in a release tied to the news. “Apple is excited to have so many excellent engineers join our growing cellular technologies group, and know they’ll thrive in Apple’s creative and dynamic environment.

Get started with Kubernetes (using Python)

Jason Haley wrote a brief tutorial to get the Pythonista started with Kubernetes. Worth reading if you are new to the topic.

Enable Kubernetes in Docker Desktop

So, you know you want to run your application in Kubernetes but don’t know where to start. Or maybe you’re getting started but still don’t know what you don’t know. In this blog you’ll walk through how to containerize an application and get it running in Kubernetes.This walk-through assumes you are a developer or at least comfortable with the command line (preferably bash shell).

Culture and Organizational Change

Just a small observation I made during AWS Transformation Day. While the entire theme for the event was on transforming business, the schedule had one track for “Culture and Organizational Change” alone. While Culture and Organizational Change is a broad and huge topic, but it is necessary and makes the difference for agility in rapidly changing and competitive markets. Amazon has been talking about this for years and they share their knowledge with their partners.

On an attempt to find out how organizations actually master this, the perspective most consultants and companies I talked to during the event shared with me was rather sobering. Anyone exhibiting at that event merely offered to run any software project under an agile management. No support, consultancy or even efforts to drive actual change, whatsoever, at least nothing that would exceed a traditional software project scope.

Cultural and Organizational Change is something requiring executive buy in and is killed quickly by means of exhaustive efforts to plan ahead. Culture needs to embrace the possibility to change quickly, throughout the process. And the wish for management is human, to have transparency and perspective early in the process, it is just as natural in the process for developers to stay vague for items that are not yet clear.

Any cultural change needs to embrace bi-directual communication and the ability to break down complex. On first thought this sounds easy, but requires plenty of cooperation and trust in a clearly defined team. Culture is rooted in clear understanding of roles, responsibilities and not to mention last, trust of all members.

Net Defender CloudFlare Goes Down, Taking Many Websites With It

The Internet was built with de-centralized infrastructures in mind. To scale globally, network providers like CloudFlare have emerged, to run decentralized infrastructures and offer them as a service. In general, keeping service independent of each others and maintaining heterogeneous networks have a proven track record of resilience, that is not necessarily inherent to the architecture of these providers. Just like Akamai had a bad day in 2004, CloudFlare today suffered from a global outage, that left many obvious collateral problems visible all over the Internet. Bloomberg, among others, reports:

CloudFlare Inc., an internet service meant to protect websites from going down, faced its own network issues on Tuesday, leading to several prominent sites — like blogging platform Medium and video game chat provider Discord — being unavailable for some time.

The colors of future

Sabine Hossenfelder googled images for ‘futuristic’ and found something puzzling. A quick experiment verified her finding. So it seems the future will not be bright but something in black and blue. Somebody really needs to figure out and in particular why the past is more orange.
