Software Engineering fundamentals matter more than ever – Rhonabwy

The manifestation of my imposter syndrome, for me and today, is what does it mean to be a software engineer. There's a lot more noise than signal on the Internet about agentic engineering, what can be accomplished, and its implications for the future. The title I chose rather gives it away; it's about choosing —

Guiding ships with Moire patterns | Tinkerings

I was inspired by Tom Scott's excellent video and links here https://www.youtube.com/watch?v=d99_h30swtM   where he talks about a particular type of "Inogon" light used to guide ships through channels or harbours. The patent is here: https://patents.google.com/patent/US4629325 and the military report on the effectiveness is here: http://www.dtic.mil/dtic/tr/fulltext/u2/a168108.pdf (Hint; They don't seem to like it much).

In this article, I will show you how I tracked down the bug. Spoiler: ultimately, patching Zsh to make it crash loudly and analyzing the crash’s core dump was the winning strategy!

Voltair (YC W26) Is Hiring a Test Flight Engineer 0

ycombinator.com

Flight Test Engineer at Voltair | Y Combinator

About Voltair Voltair is building the world’s first distributed network of drones for earth observation. We envision a world where after a major storm, an operator of critical infrastructure can simply sign into our platform and dispatch a drone. Within minutes, we will identify high risk hazards and stream issues directly to crews on the ground. With our ground stations and long range drones, we can cover the continental U.S. with only ~5000 stations.  We operate as a full stack service, meaning we build drones, deploy them, capture data, analyze it, and deliver the results on our software platform. Our first market is power utilities. We’ve serviced multiple utilities already, and are preparing for our biggest deployment with a large multinational utility later this year. The Role We’re looking for a Flight Test Engineer who is equally comfortable soldering a wiring harness on the bench and operating a 54lb fixed-wing aircraft in the field. This is not a pure R&D flight-test role and it's not a pure operations role, it's both. You'll build and validate the test fixtures and hardware that keep our flying robots reliable, and you'll deploy with that same hardware to fly real missions for large enterprise customers.  You’ll be responsible for turning our prototypes into production grade vehicles, ready to service customer contracts. You'll work closely with our hardware, software, and operations teams, and you'll be one of the people customers see in the field representing Voltair.  We expect this role to travel about ~1 week every 2 months.  You’ll be the 7th full time employee of Voltair. On day 1 we’ll begin transitions of all flight testing responsibilities from our CEO to you. Drone manufacturing will follow shortly thereafter. Within 90 days of your arrival, we expect you’ll be deploying our drone for customer contracts. Qualifications & Experiences Required - Has built drones in hobby or professional setting and understands electrical systems on drones - Experience with autopilot firmware (ArduPilot, PX4, or similar) - 1+ years of related professional experience  - Good instincts for airmanship and risk management Nice to Have - Manned aviation experience (private pilot or higher) - Experience running structured flight test plans or test campaigns - FAA Part 107 licensed
