ADVICE FOR NEW PRINCIPAL TECH ICS (I.E., NOTES TO MYSELF)

New Principal Tech Individual Contributors (ICs) should balance deep technical work with broader responsibilities such as providing vision, mentoring, and connecting teams. A large part of the role involves teaching the organization to value new ideas and driving initiatives that might not happen otherwise.

HOW WE SAVED $500,000 PER YEAR BY ROLLING OUR OWN “S3”

Nanit reduced costs by creating N3, a Rust-based in-memory landing zone for video processing, using S3 as a fallback buffer. This removed PutObject request fees and short-term storage costs associated with S3's minimum storage duration. The solution uses a two-tier fallback system, where an N3-Proxy initially redirects uploads to S3 upon N3-Storage failure, and Camera Service then completely switches to S3 presigned URLs in case of broader N3 issues.

THE JOURNEY BEFORE MAIN()

This article explains the journey from when the OS kernel is asked to run a program to when the `main()` function is executed. The kernel uses the `execve` system call to load the program, which is usually in ELF format on Linux. The ELF file contains code, data, and other information, including an entry point where execution begins.  The kernel sets up the stack with arguments, environment variables, and auxiliary vectors before jumping to the `_start` function, which then initializes the language runtime and calls the user's `main()` function.

REACT VS BACKBONE IN 2025

Despite advancements and a larger ecosystem, modern frameworks like React may not represent a large improvement over older frameworks like Backbone for simple tasks, often trading explicit simplicity for complex abstractions that can hurt understanding and debugging.

TURNING FIRST MEETINGS INTO REAL PIPELINE

If first calls aren't turning into deals, don't just push for more meetings – figure out why. Start by collecting data: run call transcripts through an LLM or have reps record structured feedback. Are you talking to the right companies, the right buyers, and saying the right things? Then tighten stage definitions so “qualified” means the same thing to everyone. Use a scorecard to rate each call on discovery, pain, and next steps to see where reps fall short. From there, build training around the patterns, role-play for storytelling, ICP refinement for targeting, and coach on urgency when deals stall. Fix the system before you add volume. Clear criteria and consistent coaching turns activity into actual pipeline.

HOW THIS STARTUP FOUND PRODUCT-MARKET FIT IN FINTECH

Casca shows how product-market fit happens when startups move from guessing to learning directly from customers. The team embedded inside banks, observing how lenders worked and solving problems as they appeared, instead of relying on assumptions or slide decks. That focus turned slow, manual loan approvals into an automated process that banks now depend on. The lesson is clear: PMF is rarely a perfect product or vision. It comes from sitting close enough to customers to feel their pain, building something that fixes it, and repeating the cycle until demand pulls you forward.

WHY PITCHES FAIL

Most startup pitches miss because founders try to explain too much. They know every corner of the business and assume investors need to, too. In ten minutes, that turns into a firehose of slides, acronyms, and backstory. However, a pitch is less about teaching and more about sparking interest. Investors don't need to understand everything, they just need to care enough to ask for another meeting. The best decks keep it simple: one clear problem, one sharp solution, a few proof points, and a story that makes sense.

A VERY OBVIOUS DEAL

Software pricing runs on psychology as much as math. Slack's promise to charge only for active users made people expect fairness tied to usage, and that mindset spread across SaaS. Once buyers learned to ask what something costs to run instead of what it's worth to them, value became harder to defend. That's dbt's problem: it powers data teams but doesn't handle the “expensive” part like storage or compute, so it looks easy to underprice. Fivetran brings scale and alignment, but not a fix to that perception. The merger matters less as a product move and more as a lesson in how pricing shapes who captures value in the modern data stack.

POWER TOOLS

Every craft has a tool powerful enough to both create and destroy. In woodworking, it's the table saw. In software, it's the IDE. Mastering them takes patience, planning, and respect. The same rule applies to design and AI tools today: no-code and generators let anyone build fast, but speed without understanding leads to fragile results. They're great for sketches, not for structures meant to last. Knowing when to reach for power and when to work by hand is what separates craft from chaos.

MAXIMIZING THE VALUE OF INDICATORS OF COMPROMISE AND REIMAGINING THEIR ROLE IN MODERN DETECTION

File hashes, IP addresses, and domains are usually seen as indicators of compromise (IoCs), but they have limited value in investigations because adversaries can easily alter them. These IoCs can be more insightful if supplemented with additional contextual data like fuzzy hashes, GeoIP information, and domain reputation. As AI enhances malware developers' abilities, IoCs will no longer serve as standalone alerts but will evolve into data points that help build a comprehensive understanding of a threat actor's behavior.

USING LLMS AS A REVERSE ENGINEERING SIDEKICK

This post demonstrates how to use LLMs with Model Context Protocol (MCP) servers integrated into IDA Pro and Ghidra to accelerate malware reverse engineering through automated function analysis, code documentation, and variable renaming. Testing on IcedID malware compared cloud-based Claude Sonnet 3.7 ($2.91-$13.24 per analysis, 18-11 minutes) against local Ollama/Devstral models ($0 cost, 22-46 minutes), with cloud models providing more thorough analysis but at a higher expense. Key limitations include token costs escalating with file complexity, context window truncation causing local models to forget instructions mid-analysis, and security risks from prompt injection, tool poisoning, and potential data exfiltration when using untrusted MCP servers.
