📰 Ubuntu’s App Center doesn’t know what went wrong

I recently re-encountered my favourite ‘error’ dialog in Ubuntu, which is thrown by the distro’s App Center (snap-store), which is the default GUI software management tool.

Firefox 154 released with small translation, AI feature and UI tweaks

Mozilla has released Firefox 154 with some small AI changes, better full-page translations and up to 10x faster video seeking (only on macOS, that one). It is also the final monthly release of Firefox before the browser switches to a faster, twice-monthly release schedule. You’ll be hearing “Firefox 155 released” in two weeks, rather than the usual four weeks between releases. So what’s new? Firefox’s been expanding its range of address bar actions in recent releases. We got tab muting action in v152 and an colour picker in v153. In 154, we get a quick link to the browser’s AI […]

Office metadata can expose more than users see—clean it before sharing

A Microsoft Office file can reveal its author, revision history, internal project details, comments, or hidden content even when the visible document looks finished. For system administrators, the practical risk is greatest when Word, Excel, and PowerPoint files leave the organization—especially documents generated or managed through SharePoint and Microsoft 365 workflows.

Alternative to WMIC: PowerShell Get-CimInstance

KB5120998 in the Windows 11 Release Preview channel removes the Windows Management Instrumentation Command-line (WMIC) utility from Windows 11 versions 24H2 and 25H2. With this update, WMIC is gone from those builds, and you cannot add it back. Windows Management Instrumentation (WMI), the service that exposes hardware and operating system data, remains in Windows. Microsoft's documented replacement for typical wmic queries is the PowerShell cmdlet Get-CimInstance.
