Thinking from across Blackshore on building software, running development firms and quantitative engineering, written for the people who build and lead.

  1. 01QuantIDEQuantIDE vs QuantConnect: Which Systematic-Trading Setup Fits You?QuantConnect gives you a mature cloud platform with a free research tier and live execution built in. QuantIDE gives you the same work on your own machine, in your own repository, under your own keys.Nov 8, 2026 · 6 min read
  2. 02QuantIDETransaction Costs in Backtesting: The Fee and Slippage Line That Changes the VerdictThe same crossover loses 0.68% at zero cost and 13.18% at 50 basis points a trade. Costs are a per-trade tax, so turnover is the multiplier — here is the full runnable code and what it actually found.Nov 7, 2026 · 7 min read
  3. 03QuantIDEWalk-Forward Validation: The Test That Keeps a Backtest HonestA backtest that only ever sees one stretch of history will flatter whatever parameters you tuned on it. Walk-forward validation re-tunes on each window and judges only on data the strategy has never seen — here is the full runnable code and what it actually found.Nov 6, 2026 · 6 min read
  4. 04QuantIDEHow to Backtest a Trading Strategy in Python, End to EndA backtest you can trust is a process, not a number: fixed data, one rule stated in advance, fees and slippage from the first run, and a judgement made only on data the strategy has never seen. This guide runs the whole process in Python, with the complete script.Nov 6, 2026 · 6 min read

  8. 08Coding CaptainThe Retainer Agency Is the Best Business You Can Start in 2026Two clients at $5,000 a month beats a junior dev job at most companies in America. Three clients at $8,000 a month beats almost any senior role. The SMB software market is starving for engineers who answer the phone, and Claude has collapsed the time it takes to deliver. This is the cleanest setup the small-business economy has produced in twenty years, and most new coders are still looking for a W-2 that doesn't want them.Nov 5, 2026 · 8 min read
  9. 09Coding CaptainSay The SentenceThe hardest part of landing your first client is not the client. It is admitting, out loud, in a normal voice, at a normal volume, to a normal person, that you run a software agency. Once you say it, the market bends toward you in a way that is almost embarrassing. People interrupt you. People hand you their phone number. People apologize for not knowing you sooner. The sentence does the selling. You just have to stop being weird about saying it.Nov 5, 2026 · 7 min read
  10. 10Coding CaptainTwo Clients Beat a JobThe software labor market broke in 2024 and nobody sent a memo. Junior engineers are sending 800 applications for 12 interviews. Meanwhile, the dentist down the street is paying $4,200 a month for a scheduling tool that doesn't do half of what she needs. The arbitrage between those two facts is the entire opportunity. You don't need a job. You need two clients.Nov 5, 2026 · 7 min read
