Apple Offers Free Downloads of OS X Lion, OS X Mountain Lion

Until now Apple charged US$19.99 to download codes for OS X Lion and OS X Mountain Lion. But now they’re free from Apple’s website.

Lion runs on Macs that came prior to the launch of Mountain Lion in 2012. Mountain Lion runs on the Macs below, but you may not be able to downgrade to it unless you completely reformat the drive. You can’t install an old OS on top of a newer one. Also, the oldest OS an M1 Mac can run is Big Sur.

Parts of AT&T’s 5G Network Will Run on Microsoft Azure Cloud

Microsoft and AT&T announced a joint venture on Wednesday that will have the carrier run core parts of its 5G network using Microsoft’s Azure cloud.

The newer generation of networks, which AT&T began rolling out in 2018, is designed to rely more heavily on software and data centers for routing traffic rather than telecommunications specific gear.

Microsoft intends to use the newly acquired technology – plus the experience gained helping AT&T run the network – to build out a product it calls Azure for Operators, which it will use to go after core network business from telecommunications companies in the 60 regions of the world where it operates.

That sounds really cool to me that some phone traffic can run through data centers. I wonder if this move would make it easier for harder for government surveillance.

New Slack Features Reflect the Changing Nature of Work

Slack has unveiled some new features to helps businesses as some workers start to return to offices, some prepare to, and others stay working remotely. Techcrunch took a look at the new tools and how they reflect the changing nature of work. It all comes ahead of the messaging service’s acquisition by Salesforce.

Let’s start with Slack Huddles, the audio tool that lets you have a real-time conversation with someone in Slack instead of typing out all of your thoughts. This will be much easier for people who find typing challenging, but the company also believes it will allow more spontaneous discussion, which mimics being in the office, at least to some degree. “Huddles is a light-weight, audio-first way of communicating right in Slack. [It] recreates the spontaneous and serendipitous interactions that happen outside of scheduled meetings,” Tamar Yehoshua, chief product officer at Slack explained in a press briefing yesterday.
