MEASURING ENGINEERING PRODUCTIVITY

This is a system for measuring engineering productivity effectively, with an emphasis on visibility and context over strict numerical evaluation. Solid productivity happens by starting small, being explicit with expectations, and being open to feedback to ensure the system serves as a tool for improvement rather than a weapon for punishment.

YOU CANNOT OUTSOURCE UNDERSTANDING

Businesses often try to eliminate developers, believing they can achieve software benefits without them, but this approach consistently fails. The core issue is that software development isn't just about production, it's about understanding and adapting to complex business needs, which cannot be outsourced, automated, or abstracted away.

SOLVING THE WRONG PROBLEM

AI-assisted coding, despite its impressive capabilities, may be addressing the wrong problem in software development. AI agents often recreate existing code due to the nature of LLMs and training data. Furthermore, AI is primarily benefiting less experienced developers and masking underlying issues like inadequate software engineering education and a focus on speed over quality.

THE PROGRAMMER IDENTITY CRISIS

The rise of AI and LLMs threatens the core identity of programmers as craftspeople. Vibe-coding and specification engineering have turned programmers into operators rather than creative problem-solvers. This shift removes a lot of the joy and fulfillment of programming.

LLMS CAN GET "BRAIN ROT"!

Continuous exposure to low-quality, "junk" web data can cause a lasting cognitive decline in LLMs. Through controlled experiments, researchers found that pre-training LLMs on data from X selected for high engagement or sensationalism negatively impacted reasoning, long-context understanding, and ethical behavior. The primary error was identified as "thought-skipping," where models truncated reasoning steps, and standard fine-tuning methods only partially mitigated the damage, showing a persistent change in the models' representation.

POE BASICS AND BEYOND: WHAT EVERY ENGINEER SHOULD KNOW

Power over Ethernet (PoE) delivers both data and power over standard Ethernet cables to devices like IP cameras and VoIP phones. This article explains the difference between endspan (PoE-enabled switches) and midspan (PoE injectors) devices, along with the evolution of PoE standards (IEEE 802.3af/at/bt) to support higher power levels.

GETTING DEEPSEEK-OCR WORKING ON AN NVIDIA SPARK VIA BRUTE FORCE USING CLAUDE CODE

Claude Code can be used to get DeepSeek-OCR running on an NVIDIA Spark by automating the process within a Docker sandbox. Initially, Claude Code struggled to do this due to PyTorch and CUDA compatibility issues, but after being suggested different PyTorch versions, Claude Code found a compatible version and completed the task. Claude Code generated notes, scripts, and documentation, including a performance comparison of different prompts for OCR.

THE DEATH OF THREAD PER CORE

Data processing has shifted away from thread-per-core models due to increasing core counts, improved IO speeds, and the need to handle skewed data distributions effectively at the data processing layer itself.
