Microsoft fixes unreachable Windows Server domain controllers

Microsoft has resolved a known issue that caused some Windows Server 2025 domain controllers to become unreachable after a restart and triggered app or service failures. As Redmond explained when it acknowledged the bug in April, servers loading the standard firewall profile instead of the domain firewall one after rebooting will have issues managing network traffic correctly. Because of this issue, services and applications running on impacted domain controller servers or remote devices may f

Why OpenAI and Google's surprising new alliance makes a lot of AI sense

MF3d/Getty Images In geopolitics, nations with conflicting societal norms or ideological views must occasionally form alliances in the interest of protecting their mutual interests; practicality must take precedence over past rivalries. Today, a similar dynamic is starting to play out in the AI arms race. OpenAI, the AI start-up that skyrocketed to global fame following the viral success of its ChatGPT chatbot, has teamed up with Google, its longtime competitor, according to a Reuters report.

Why Denmark is dumping Microsoft Office and Windows for LibreOffice and Linux

Alexander Farnsworth/Getty Images Denmark's Minister of Digitalization, Caroline Stage, has announced that the Danish government will start moving away from Microsoft Office to LibreOffice. Why? It's not because open-source is better, although I would argue that it is, but because Denmark wants to claim "digital sovereignty." In the States, you probably haven't heard that phrase, but in the European Union, digital sovereignty is a big deal and getting bigger. A combination of security, economi

Here's how I finally cracked a tricky Linux problem with this AI terminal app

Warp is scary good at fixing problems. Screenshot by Jack Wallen/ZDNET I've been using Linux for a very, very long time, and it's rare that I encounter an issue I cannot resolve. However, a few weeks ago, such a problem occurred. The issue was caused by an installed application upgrade that required a dependency that the apt package manager couldn't solve.

Characterizing my first attempt at copper-only passives

Characterizing my first attempt at copper-only passives¶ Last year, I kind of got a bee in my bonnet about trying to see if I could accurately (?) make small RF passives out of copper, rather than buying 2pF NP0 capacitors or something, as part of a long-on-the-horizon project to make extremely inexpensive GHz-class oscilloscope probes. I figured that the right place to start was to fab out a board on JLCPCB's JLC04161H-3313 stackup with a handful of calibration standards, and some of the passi
