Whack-a-drone

In Pasadena, California, there's a cute red brick courtyard where one storefront isn't like the rest. The glass doors open onto a sparse industrial hallway, which leads to a sunlit foyer with a large spiral staircase. Go up, and you'll see a typical coworking space: open tables, healthy snacks, a collection of meeting rooms with […]

TikTok’s protection of minors should not be opt-in, warns EU

TikTok has attracted the ire of the European Union over its protection of children who use the video sharing platform. The European Commission announced preliminary findings today under the Digital Services Act (DSA) that offer specific issues to address. The Commission suggests that TikTok should adjust the default settings of minors' "public" accounts so the […]

I Spent 3 Weeks Debugging Rate Limits Before I Realized the Problem Wasn't My Code

Ever chased a bug for days, only to discover the "bug" was actually the platform working exactly as designed? That happened to me building a client reporting pipeline. The lesson stuck. Here's what nobody tells you about pulling marketing data from multiple ad platforms: the hard part was never the dashboard. It was everything underneath it. The Setup That Looked Simple on Paper The brief sounded easy. Pull spend, clicks, and conversions from Google Ads and Meta. Store it. Display it in a chart. A junior dev could knock this out in a sprint, I figured. Reality disagreed. Google Ads API enforces operation quotas per developer token, and those quotas scale differently depending on account tier. Meanwhile, Meta's Marketing API throttles based on a rolling usage score tied to the ad account itself, not your app. Two platforms. Two completely different throttling philosophies. Neither documented in a way that made the actual limits obvious until you hit them in production. Where Things Actually Broke My first version polled every client account every hour. Fine for three clients. Then we onboarded client number twelve, and Meta started returning 429s intermittently. Not consistently — intermittently. That's the worst kind of bug. I initially assumed it was a code issue. Retry logic, maybe a race condition in my job scheduler. I spent three weeks going down that path. Eventually, I found the real cause: cumulative API call volume across all client accounts was tripping Meta's app-level rate limit, not the individual account limit. The fix wasn't more retries. It was a request queue with exponential backoff, plus a priority system so active dashboards refreshed before idle ones. Simple in hindsight. Expensive in dev hours. The Real Architecture Behind Multi-Platform Reporting If you're building this yourself, here's what a production-grade pipeline actually needs, based on what broke for me. A Queue, Not a Cron Job Don't just fire off API calls on a schedule and hope for t

Google hit with $1 billion fine for breaking EU antitrust rules

The European Union has fined Google's parent company Alphabet €890 million (about $1 billion) for two separate violations of the bloc's Digital Markets Act (DMA). One penalty is for giving its own products preferential treatment in search results, while the other is for blocking Android developers from sending users to alternate payment options. A €460 […]

The First Computer Bug Was a Real Moth

If you have ever stared at a misbehaving circuit at two in the morning, muttering about the "bug" you cannot find, you are part of a lineage that runs back to a very literal insect. On September 9, 1947, engineers working on Harvard's Mark II computer opened up the machine, found a moth wedged inside a relay, and taped it into their logbook. The note beside it reads: "First actual case of bug being found." It is one of the most charming artifacts in the history of computing, and it carries a surprisingly practical lesson for anyone who builds connected hardware today. What actually happened in 1947 The Mark II was an electromechanical monster: a room-sized calculator built from thousands of relays, switches that physically clacked open and closed to represent ones and zeros. On that September day the machine was producing errors, and the operators -- part of the U.S. Navy computing effort that Grace Hopper worked in -- traced the fault to Relay #70 in Panel F. Inside was a moth, its wings shorting across the contacts. They removed it, taped it into the logbook at 15:45, and recorded the now-famous line. That page, moth still attached, lives today in the Smithsonian's National Museum of American History. Hopper loved telling the story for the rest of her career, which is why her name is forever attached to it. She is often credited with coining "bug" and "debugging" because of that moth, but the honest history is a little different, and the difference is the interesting part. The word "bug" was already old Engineers had been calling faults "bugs" for decades before 1947. Thomas Edison used the term in an 1878 letter to describe the little glitches and "difficulties" that show up when a new invention meets the real world. By the early twentieth century "bug" was common shop-floor slang among electrical and telephone engineers. So the moth did not invent the word. What made the logbook entry so memorable is the joke buried in it: "first actual case of bug being found"
