Tigera extends cloud-native networking with Calico 3.30



This logging functionality is uncovered by way of two new elements:

  1. Goldmane: A gRPC-based API endpoint that aggregates movement logs from Calico’s Felix element, which runs on every node.
  2. Whisker: An online-based visualization software constructed with React and TypeScript that connects to the Goldmane API.

The mix of those elements supplies detailed visibility into community visitors patterns inside Kubernetes clusters, addressing a typical ache level for Kubernetes directors who must troubleshoot connectivity points or confirm safety insurance policies.

Staged insurance policies allow safer community coverage implementation

Community insurance policies in Kubernetes are highly effective however probably disruptive if misconfigured. Calico 3.30 introduces staged insurance policies that permit directors to check coverage adjustments earlier than enforcement.

Kelly defined that staged coverage permits community directors to do a dry run of what would occur if a selected coverage is utilized in a Kubernetes cluster. Calico 3.30 is ready to generate movement logs to simulate the affect of how the applying of a selected coverage will affect the cluster. This strategy considerably reduces the chance of service disruptions when implementing community insurance policies, as directors can validate coverage habits earlier than committing to enforcement.

Hierarchical coverage administration with tiers

Past the power to validate coverage earlier than implementation, Calico 3.30 provides new layers of coverage granularity general. Calico 3.30 additionally brings coverage tiers to the open-source version, enabling extra refined coverage administration.

The tier system permits organizations to implement defense-in-depth methods and preserve clear separation between safety insurance policies and application-specific community guidelines. It additionally underpins Calico’s implementation of the Kubernetes Admin Community Coverage function, which is presently in alpha within the Kubernetes undertaking.

swift – iOS 17 Bug? Including a .sheet to a .fullscreencover makes background opaque


I’m engaged on making a customized Popup View based mostly on a .fullscreenCover. The .fullscreenCover is used to put the Popup content material on display on a semi-transparent background.

Whereas this works on iOS 18, there’s a drawback on iOS 17: When the Popup content material accommodates a .sheet, the background is just not clear any extra however opaque.

enter image description here
enter image description here

    1. Picture: iOS 17. When exhibiting the Popup an opaque background covers the principle content material. When tapping on the background it turns clear.
    1. Picture: iOS 18. All the things works as meant. When exhibiting the Popup the principle background is roofed with a semi-transparent background.

Eradicating the .sheet(...) from the Popup content material solves the issue. It doesn’t matter if the sheet is used or not. Including it to the view code is sufficient to set off the issue.

Utilizing a .sheet inside a .fullscreenCover shouldn’t be an issue so far as I do know.

Is that this a bug in iOS 17 or is there one thing mistaken with my code?

Code:

struct SwiftUIView: View {
    @State var isPresented: Bool = false
    @State var sheetPresented: Bool = false
    
    var physique: some View {
        ZStack {

                Colour.yellow.body(maxHeight: .infinity)
                Colour.blue.body(maxHeight: .infinity)
            }

As a part of Cisco’s “Plan for Attainable,” our environmental sustainability technique, I typically emphasize the significance of resilient ecosystems. A necessary side of resilient ecosystems is guaranteeing communities have the talents, instruments, and sources to help the event and deployment of unpolluted vitality. Power resilience shouldn’t be solely about infrastructure; it’s basically about folks. Communities can profit from clear vitality options, equivalent to microgrids and photo voltaic storage, however a talented workforce and progressive applied sciences are wanted to maintain these initiatives.

Many sectors, together with manufacturing, expertise, and building, want expertise that may assist enhance effectivity, scale back utilization of uncooked supplies, decrease waste, and assist shield the surroundings. Actually, a 2024 report from LinkedIn signifies that such expertise “are more likely to turn out to be more and more vital because the business confronts the complexities of overhauling the facility grid.”

By investing in coaching, expertise, and partnerships, we can assist to construct in resilience from the bottom up and assist folks to take management of their vitality future.

Lately, we held a dialogue on this matter with three nonprofits funded by way of the Cisco Basis, and right here’s what they needed to share:

Kara Photo voltaic

Kara Photo voltaic started in 2012 as a dream to construct a solar-powered boat. They now help a thriving community of photo voltaic transport and vitality hubs in Achuar territory within the Ecuadorian Amazon and are starting to copy the mannequin with extra communities throughout the Amazon area. By optimizing designs, offering technical coaching, constructing native provide chains, and facilitating financing, Kara Photo voltaic allows Indigenous communities to entry, implement, and handle photo voltaic transportation and vitality programs in their very own territories, on their very own phrases. Essential to the mannequin is in-depth native capability constructing. Kara Photo voltaic has educated Indigenous technicians to put in and preserve group microgrids that save gasoline, scale back carbon emissions, and help Indigenous communities in constructing native financial energy and preserving rainforest ecosystems.

Oliver Utne, founding father of Kara Photo voltaic shared, “We frequently say that the Amazon is a cemetery of failed initiatives. As a result of companies will are available in, set up photo voltaic or another type of technological resolution, inform the native folks don’t contact this, after which they depart. The DNA of our group from the very starting was about co-design; it was about how can we get the proper heads collectively that haven’t been collectively prior to now? Our coaching technique is all about studying by doing hands-on, and  more and more peer-to-peer-training as a result of now there’s this actually strong core of Indigenous technicians who’re coaching different folks.”

Pantheon of faculty soccer will get a Wi-Fi improve



Notre Dame has totally adopted cellular ticketing and launched grab-and-go concession stands, with plans to increase them additional. Alcohol gross sales have been not too long ago permitted, prompting efforts to help new providers like cellular carts. In premium areas, followers can stream varied video games throughout occasions. Notre Dame additionally examined cellular ordering for concessions with pickup alerts.

As they are saying in infomercials, “however wait, there’s extra…” The college is regularly exploring new methods to make the in-person expertise even higher. For instance, it’s going to supply unique digital camera angles and real-time stats, solely accessible by way of Wi-Fi on the stadium. It’s all a part of an effort to provide followers one thing they will’t get watching at house. (See additionally: AI commentary goes into full swing at Gamers Championship)

“One of many challenges numerous lot of sports activities venues face is getting individuals to pay to come back to the sport, once they can sit at house with their massive TV and have an analogous expertise from the consolation of their sofa,” stated Buysse.

Behind the scenes, the stadium has additionally grow to be a testing floor for superior tech, in partnership with Federated Wi-fi and Notre Dame’s personal Wi-fi Institute. Federated Wi-fi helped the college handle the challenges of utilizing the brand new 6 GHz Wi-Fi band open air. Usually, too many units utilizing the identical sign may cause interference. Federated Wi-fi’ cloud-based system, Automated Frequency Coordination (AFC), prevents interference by organizing how completely different units share the sign. Consequently, the stadium’s Wi-Fi is now stronger, covers extra floor, and might deal with extra individuals directly.

In the meantime, the Wi-fi Institute is piloting a personal 5G community to see how connectivity could be improved for each college students and units throughout campus. Whereas personal 5G isn’t coming this yr, Buysse stated the college can be “transitioning back-of-house communications” to make sure that vital providers, comparable to campus public security, all the time keep linked no matter how busy the community will get.

For now, Notre Dame directs everybody to Wi-Fi as a result of the stadium’s mobile community is outdated and struggles to maintain up with demand. Though enhancements to mobile service are being made, progress has been gradual as a result of varied challenges. Particularly, mobile carriers wish to set up gear within the bowl of the stadium, however the venue’s construction makes that tough with out impacting the aesthetic.
