Elon Musk purchases Twitter and Does what Musk Does | Gestalt IT Rundown: November 2, 2022

November 2, 2022

While not completely enterprise tech, we felt like it was necessary to cover the Twitter saga since so many of us use social media to share information and build our communities. The acquisition of Twitter by Elon Musk closed on Thursday after the market closed. From there the new owner of the platform fired the CEO, CFO, and chief legal counsel. He dismissed the board of directors this week to become the sole head of the company. He also brought in a number of engineers from Tesla and SpaceX to start interviewing Twitter developers and understand how the code works for the platform. The catch? Tesla and Twitter develop in two entirely different langagues. These reports come amid rumors that people are being forced to work 80 hour weeks and that there will likely be looming layoffs coming very soon. To top it all off, Elon’s grand plan to make Twitter profitable now seems to be around charging more for Twitter Blue, the premium service. The initial report was that Musk wanted to charge $20/month and include verification for the service. Many users balked publicly, including celebrities such as author Steven King. Musk backpedaled quickly and offered a compromise of $8/month, which is still almost double the current cost but users are wary of what that would entail. Nathan, this is a massive pile of craziness and Elon hasn’t even owned them for a week!

FAA Wants 5G Limits | Gestalt IT Rundown: October 26, 2022

October 26, 2022

The story that never seems to fly away has circled back once again. The FAA has as the FCC once again to delay the deployment of C-Band 5G frequencies around airports. The line of reasoning is still that flights could be disrupted becaue of the potential impact of these frequencies on plane altimeters. A new wrinkle in the discussion is that the FAA now states that even the radio filters that are being rapidly installed in airplanes may not be enough to shield them from spurrious transmissions. The other question is whether or not the FCC has the authority to impose restrictions on the spectrum after it was auctioned off. Chris, you know a bit about this space. What do you think is the end result here? This and more on the Gestalt IT Rundown. Head to GestaltIT.com for show notes.

Nutanix Looking For A Buyer? | Gestalt IT Rundown: October 19, 2022

October 19, 2022

The rumors are swirling that there is interest in Nutanix being sold or taken private. A number of reports appeared at the end of the week last week noting that discussions had been taking place with private equity investors about buying up outstanding shares in the company to take it off of Wall Street. The value of Nutanix today is reported to be about $6 billion, which is down from the valuation last year of over $9 billion but also much better than the $3.1 billion that was reported as late as June of this year. Though no companies have been mentioned in the rumors specifically there is a lot of interest in the hyperconverged infrastructure pioneer should they decide to be taken over. Max, you’ve worked a lot with Nutanix and you know the market. What’s going to happen here?

Alder Lake Leaks BIOS Source | Gestalt IT Rundown: October 12, 2022

October 12, 2022

Intel isn’t happy that the source code for their Alder Lake BIOS has been leaked online. The UEFI code was nabbed by someone and posted to the Internet as a 6 GB file containing all kinds of secret things. One of the big finds is the private key for Intel Boot Guard, a seuciry feature designed to create a secure booting environment. No official word has been released on who leaked the data but signs point to an ODM in China that created a Github repository that was cloned and distributed rapidly. Tom, how bad is this for Intel?
