Three of the principals from the early days of id Software shared some faintly maudlin but ultimately uplifting reminiscences from those long-ago days.

Room-temperature laser hits record stability with 68-cm optical cavity
Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser technology. The team’s results have been published in Optica.
Ultrastable lasers produce light of exceptional spectral purity and are a critical enabling technology for optical atomic clocks. These are the next generation of atomic clocks based on atomic transitions in the optical domain. These clocks underpin the most precise timekeeping ever achieved and are central to future technologies ranging from advanced navigation to fundamental physics.
The NPL team measured a fractional frequency instability of 4 × 10⁻¹⁷, achieved for the first time using a room-temperature optical reference cavity. Until now, comparable performance had only been realized internationally using complex cryogenic systems.
Mandiant reveals how Cisco SD-WAN zero-day attacks gained root access
New details have been revealed on how hackers exploited a Cisco Catalyst SD-WAN vulnerability tracked as CVE-2026–20245 in zero-day attacks to create rogue root accounts on targeted devices.
The CVE-2026–20245 vulnerability is a high-severity command injection flaw in Cisco Catalyst SD-WAN Manager (vManage), Controller (vSmart), and Validator (vBond) that allows authenticated attackers to execute arbitrary commands as root by uploading a crafted file.
Cisco said the vulnerability stemmed from insufficient validation of user-supplied input and could be exploited by authenticated attackers with local access to affected devices.
