Tales from a Seasoned Developer: Gifted Millions to Clients, Fried Hardware, Angered Politicians

Free Stocks for Everyone! Bring Your Bags.

I once led development for a brokerage application with buy and sell functionality. The system had an API covered with automated tests. One day, the tests accidentally connected to the production environment instead of the staging one and executed real operations on client accounts.

One client discovered unexpected shares of a gas giant plus foreign currency in his account. Instead of contacting support, he started selling them off. The more assets appeared, the more furiously he acted, ultimately creating a short position worth a significant sum of money.

Management had to intervene — unwinding the mess took considerable effort. And we learned the hard way: always triple-check your environment configurations.

Follow the White Rabbit

Twenty years ago, I accidentally walked into my boss's office while he was watching adult content. We both pretended nothing happened. When the boss called in sick, young me grabbed an external hard drive, visited his office, and copied his extensive collection of files.

Looking back, I'm not proud of it. But at the time, it seemed like the most natural thing to do when you're a young programmer with a small hard drive and unlimited curiosity.

Hardcore with the Penguin

My attempt to install Linux alongside Windows 95 ended tragically. The Linux installer corrupted the Master Boot Record of the disk that contained all the documentation for my father's engineering design bureau.

Without internet access and zero experience in data recovery, I resorted to the diskedit.exe utility. I manually searched for the "DOC" signature (the header of Word 95 documents) and copied the fragments I found. The process took three days of 14-hour shifts, and I managed to recover about 80% of the files.

My father wasn't thrilled, but the fact that most of his documentation survived saved me from a fate worse than a corrupted boot record.

The East Is a Delicate Matter

In the early 2000s, I worked for an Indian entrepreneur who sold equipment to dairy plants. The boss employed every trick in the book: fines, salary delays, and psychological pressure on employees.

When I tried to resign, I was buried under a mountain of work with promises that my final pay and employment record book would come later. Confident that the boss didn't have enough local connections or real "protection," I told him that a virus had corrupted the company's document management system.

I offered to help fix it — but only after receiving my full salary and employment record book. I hinted at possible countermeasures if things didn't go my way.

The boss agreed. I "fixed" the WinRAR encryptor issue and resigned peacefully. Sometimes you have to speak the language your employer understands.

Critical Bug

Our team was building software for epidemiologists that visualized disease outbreak hotspots on a map. During a demonstration at the Armenian Ministry of Health, the full-screen map displayed... Baku. After zooming out a bit, the entire territory of Azerbaijan appeared on screen.

The Armenian minister was visibly irritated and demanded that the image be removed immediately. This was a critical bug that required an emergency rebuild of the distribution package. In software development, geography is not just about coordinates — it's about geopolitics.

Incendiary Debugging

Early in my career, I was tasked with creating a fault-tolerant communication protocol on an ARM microcontroller for a radio modem. Using an oscilloscope helped me debug the prototype to a working state.

The demonstration to the director ended in disaster: when I connected the device to the director's laptop — which cost more than half a year of my salary — the screen went black. The equipment emitted the unmistakable smell of burning electronics.

Later investigation revealed that the desk was connected to two power outlets from different electrical phases. It was this phase mismatch, not my device, that damaged the laptop's motherboard. The hardware engineers managed to repair the board in a single day.

But for those few hours between the smoke and the diagnosis, I aged about ten years.
