Lgd. Viktor Klang @viktorklang.com · 28/07/2026Today I realized that the evolutionary justification of the existence of orange cats is because their prey is dichromatic, meaning that they appear as green to their prey. 000

Lgd. Viktor Klang @viktorklang.com · 16/06/2026One of my kids attended a summer break activity today and when I picked him up afterwards he was complaining that one of the adults had been misleading the kids. Turns out that the adult had told the kids that Earth is round. A sphere. My kid: No it isn’t, it’s a geoid. He’s 12yo 😅 020
Lgd. Viktor Klang @viktorklang.com · 07/06/2026It also meant that if a user reached out due to an issue, in most cases someone was already working on a fix. THAT builds trust. 021
Lgd. Viktor Klang @viktorklang.com · 07/06/2026A ”trick” we used decades ago was to have the system automatically open bug-tracked issues (deduplicated by cause of course) for all ”unexpected” exceptions. That paired with such features having very high priority to get resolved meant that for each day without a new feature, the system got better. 121
Lgd. Viktor Klang @viktorklang.com · 07/06/2026I am terrible at parties. I caught myself using the phrase ”so I read this research paper the other day which …” like 5 times within the span of 20 minutes today. 020

Lgd. Viktor Klang @viktorklang.com · 09/05/2026Weekend musings: what I am most proud of is not the things I’ve built (or helped build) but learning that something I did or said had a meaningful impact on someone else’s way of thinking. I definitely did not see that coming when I started working some 25 years ago. 141

Lgd. Viktor Klang @viktorklang.com · 15/02/2026Spent a bit of time to pretend to be a network technician over the past month and moved many devices to use wired ethernet—not only does this really improve latency for those devices, but it also has freed up a bunch of bandwidth for the wifi-connected devices. Worth it! 140
