Photonic technologies that operate in the ultraviolet UV-C range (100−280 nm) play an important role in fields ranging from super-resolution microscopy to optical communications. As these technologies improve, they are expected to open new pathways across science and engineering. One of UV-C light’s most valuable traits is how strongly it scatters in the atmosphere, which makes it especially useful for non-line-of-sight communication. This property allows data to be transmitted even when obstacles block a direct path between sender and receiver. However, despite this promise, progress has been slowed by the lack of practical components capable of working reliably with UV-C…

Amazon SageMaker announced a new feature that you can use to add custom tags to resources created through an Amazon SageMaker Unified Studio project. This helps you enforce tagging standards that conform to your organization’s service control policies (SCPs) and helps enable cost tracking reporting practices on resources created across the organization. As a SageMaker administrator, you can configure a project profile with tag configurations that will be pushed down to projects that currently use or will use that project profile. The project profile is set up to pass either required key and value tag pairings or pass the key of…

The founder of a spyware company that encouraged customers to secretly monitor their romantic partners has pleaded guilty to federal charges – marking one of the few successful US prosecutions of a stalkerware operator.Bryan Fleming, who ran the now-defunct surveillance software company pcTattletale from his luxurious home in Michigan, entered a guilty plea on January 6 in a San Diego federal court to charges including computer hacking, conspiracy, and the unlawful advertising of surveillance software.The case is significant not just for its rarity, but for how brazenly Fleming operated. Unlike many stalkerware operators who hide behind anonymity, Fleming openly promoted…

I’ve taken a liking to a few particular apps that have a color/background behind their toolbar at the top of the view, as if to emphasize the navigation titles/headers, but then you can scroll past it. I’m targeting iOS 26. This is basically what I have so far, which leaves me a normal colored toolbar, that’s sticky: struct ContentView: View { var body: some View { NavigationStack { ScrollView { ForEach(0..<50, id: \.self) { index in Text("\(index)") } .frame(maxWidth: .infinity) } .toolbarBackground(.blue, for: .navigationBar) .toolbarBackground(.visible, for: .navigationBar) .toolbar { ToolbarItem(placement: .topBarLeading) { Text("Title") .fontWeight(.bold) .font(.title2) .fixedSize() } .sharedBackgroundVisibility(.hidden) } }…

I listen to a lot of music, it’s a constant accompaniment to my work and our evening relaxing. I don’t use streaming services, every couple of weeks I buy a bunch of digital albums and listen to them every day until we’re ready for a new batch. Here’s my favorite six from last year’s listening. I’ve long been a fan of the explosive brass from Balkan wedding bands, and Fanfare Ciocărlia are a prime example of the style. This is energetic blowing from a tight band that gets the adrenaline flowing. On this album they combine with Canadian jazz-rock guitarist…

Modern software development is more complex than ever. Teams work across different operating systems, chip architectures, and cloud environments, each with its own dependency quirks and version mismatches. Ensuring that code runs reproducibly across these environments has become a major challenge that’s made even harder by growing concerns around software supply chain security. Nix is a powerful open-source package manager that builds software in controlled, declarative environments where dependencies are explicitly defined and reproducible. Its functional approach has made it a gold standard for reproducible builds, but it can also be difficult to learn and adopt. Flox is a company…
