Cisco on Thursday announced an agreement to buy cybersecurity and observability company Splunk for about $28 billion.

The big picture: Legacy tech giants are usually the last to recognize they're being disrupted, but that doesn't seem to be the case with AI.

Expect a lot more of these sorts of mergers, even if the targets aren't AI-native. Details: The $157 per share offer represents over a 31% premium to Wednesday's closing price for Splunk shares.

The last time Splunk traded above $157 per share was in early 2021. It's the networking giant's largest acquisition. Cisco says the merger will add roughly $4 billion in ARR, boosting its subscription and recurring revenue efforts. The purchase price will be financed via a combination of cash and debt, with a final closing by the end of Q3 2024, the company said. What they're saying: "This will help our customers move from threat detection and response to threat prediction and prevention," said Cisco CEO Chuck Robbins during a conference call Thursday morning.

"In terms of observability, our complimentary capabilities will offer observability for the full IT stack, from the application to the network, across hybrid and multi-cloud environments." Editor's note: This story was updated with additional details about the deal.

On Wednesday, OpenAI announced DALL-E 3, the latest version of its AI image synthesis model that features full integration with ChatGPT. DALL-E 3 renders images by closely following complex descriptions and handling in-image text generation (such as labels and signs), which challenged earlier models. Currently in research preview, it will be available to ChatGPT Plus and Enterprise customers in early October.

Like its predecessor, DALLE-3 is a text-to-image generator that creates novel images based on written descriptions called prompts. Although OpenAI released no technical details about DALL-E 3, the AI model at the heart of previous versions of DALL-E was trained on millions of images created by human artists and photographers, some of them licensed from stock websites like Shutterstock. It's likely DALL-E 3 follows this same formula, but with new training techniques and more computational training time.

Judging by the samples provided by OpenAI on its promotional blog, DALL-E 3 appears to be a radically more capable image synthesis model than anything else available in terms of following prompts. While OpenAI's examples have been cherry-picked for their effectiveness, they appear to follow the prompt instructions faithfully and convincingly render objects with minimal deformations. Compared to DALL-E 2, OpenAI says that DALL-E 3 refines small details like hands more effectively, creating engaging images by default with "no hacks or prompt engineering required."

Summary: This article provides a brief introduction to commonly used virtual network interface types in Linux, including bridge, bonded interface, team device, VLAN, VXLAN, MACVLAN, IPVLAN, MACVTAP/IPVTAP, MACsec, and more. It explains what these interfaces are, their differences, when to use them, and how to create them. It is a useful resource for anyone with a network background.

Comments: This article is an introduction to Linux interfaces for virtual networking, explaining the fundamentals and providing insights into SR-IOV. It discusses how SR-IOV allows a single hardware device to act as multiple virtual devices, improving performance and reducing overhead. The article also mentions the book 'The Linux Programming Interface' as a resource for learning more about Linux interfaces for virtual networking.
