Episode: The Most Dangerous Shortcuts in Software
Date: January 2, 2026
Host: Ryan Donovan
Guest: Tom Totenberg (Head of Release Automation, LaunchDarkly)

Episode Overview

This episode explores the risks and realities of taking shortcuts in software development, particularly focusing on "dangerous shortcuts"—those decisions and hacks that can undermine software stability, security, and sustainability. Host Ryan Donovan sits down with Tom Totenberg to dissect where these shortcuts come from, why they're tempting, how they manifest, and strategies for balancing speed and safety in release automation. The conversation moves from personal anecdotes to deep industry practices, discussing everything from homebrew tooling and tech debt to the impact of AI-generated code and organizational culture.

Key Discussion Points & Insights

1. The Nature of Shortcuts in Software

• Laziness as a Virtue and Vice
  • Some of the best engineers are "fundamentally lazy," seeking ways to automate or streamline (03:05).
  • “If you are measuring something, they will try to gamify that measurement. And as long as the reports look good, as long as it’s easy and they’re not getting bothered, they’re going to take whatever shortcut they want. So yeah, happy to get into specifics there, but it’s like water, right? It’s going to flow wherever it’s easiest to go.” — Tom, (02:51)
• Historical and Emerging Shortcuts
  • From homebrewed tools that scale unintentionally to configurations that bypass safety nets, shortcuts often originate from practical necessity but balloon into critical risks (03:36).
  • The impact of increasing business pressure to “move faster and faster” often leads to such shortcuts.

2. Homebrew Tooling & the Automation Trade-off

• The Age of Homebrew Tooling
  • “We’re about to enter a golden age of homebrew tooling.” — Ryan, (05:28)
  • With the barrier to entry lower than ever, more developers create their tooling, increasing the likelihood of fragile, ad-hoc solutions operating in critical environments (05:32).
• AI-generated code and Disconnected Review
  • Tom warns against a peer review process that allows a developer to generate code with AI, review it themselves, and merge without a second set of eyes.
  • “If it’s AI generated code, we need at least two humans because that will make sure that one person isn’t going to be the person who shoves something out the door with the assistance of Claude or Gemini or whatever LLM you’re relying on.” — Tom, (07:09)

3. Shortcuts, Tech Debt, & Long-Term Impacts

• Taking shortcuts often results in technical debt—quick MVPs launched without foundational planning can be costly to unwind later (08:55).
  • “If we are not taking the time, if we are just vibing out or just, you know, taking the shortcut as a human and saying, yeah, I’ll get the MVP out the door without really considering where this could grow in the future. That absolutely is tech debt, because it means that you’re going to have to cause yourself and your team more work down the road to refactor everything that you did, which is so much tougher to unwind later, rather than just building it up in the first place.” — Tom, (09:38)

4. Business Pressures vs. Sustainable Pace

• Much of the push towards shortcuts and unsafe practices is driven by top-down speed mandates (10:10).
  • Tom emphasizes the importance of comprehensive planning, "not just defining what is this individual thing that we are building, but where does this fit into the overall picture?" (10:55)
  • “If it takes you one and a half times to build this in an extensible way, then that is better than the 2x time from a business perspective that it would have taken to build it twice.” — Tom, (11:37)
• Defining clear success and failure criteria up front—even at the risk of "rep(ping) waterfall" for the sake of thoughtful planning (12:28).

5. Organizational Structure and Coordination

• The move toward smaller, nimble, agile teams can be a double-edged sword, sometimes leading to duplicated effort and conflicting solutions—a source of tech debt and confusion (12:40).
• Centralized, top-down strategy (à la Amazon/Bezos) can bring clarity and scalable interoperability (14:50), versus “folk engineering” and scattered best practices that eventually demand consolidation (20:18).

6. Release Automation: Slow Is Fast

• The podcast defines a sustainable release process as one that invests in upfront automation and control, then reaps speed and safety dividends over time (24:17).
  • “This is where go slow to go fast...we should be able to have not just the control strategy, but the measurement strategy. Right. So how do you actually know? How will you confirm that this thing is going well?” — Tom, (24:32)
• The importance of release controls, fine-grained rollouts, and central observability—so issues can be detected early and the blast radius contained (24:17–27:40).

Notable Quotes & Memorable Moments

• “If you want something done efficiently, give it to a lazy man.” — Ryan, quoting a Bill Gates saying, (03:05)
• “Homebrewed tooling…this sort of duct tape connector that wasn’t necessarily intended to be load bearing, but someone had a solution…until it reaches some sort of scale, causes some sort of incident, and bang, now you’re in trouble.” — Tom, (03:36)
• On the risk of rubber-stamping reviews and AI-generated code:
  “If you want your PR to fail, make it 10 lines long. If you want it to succeed, make it 10,000 lines long. Because nobody’s going to review that.” — Tom, (08:06)
• “It’s almost like there’s this folk engineering going on where everybody in the bottom is just sort of like getting their piecemeal, their little parts to make the thing. And somebody has to put together the canonical version.” — Ryan, (20:18)
• On the executive “laser beam” that can cut through organizational inertia—sometimes helpfully, sometimes destructively:
  “It could also be personnel changes in leadership too…Let’s onboard exactly the same setup as we had at the last place. Consequences be damned…” — Tom (20:56)

Summary

This episode delves into the “most dangerous shortcuts” in software—those decisions made under pressure or out of convenience that put systems and companies at risk. Tom Totenberg highlights the importance of investing in standardized release automation processes, proper planning, and thoughtful organizational design. Listeners are cautioned against “duct-taped” homebrew tools, AI-generated rubber-stamped code, and the unchecked spread of tech debt. The essential lesson: slow, deliberate planning creates paved paths that accelerate safe, reliable delivery. As tools, teams, and technologies evolve (especially with the rise of AI), software professionals must re-emphasize planning, measurement, and cross-team coordination to endure and thrive.
