Design a resilient job scheduler with retries, backoff, and idempotent task execution semantics
Create a language-agnostic design for a distributed job scheduler supporting retries, exponential backoff, idempotency keys, and dead-letter queues. Provide core data structures, failure scenarios, and pseudocode for enqueue, claim, heartbeat, and completion.
Build a tiny interpreter with parsing, AST evaluation, and helpful error messages from scratch
Write a plan to implement a small expression language (variables, functions, conditionals). Include grammar, tokenizer, recursive-descent parser, AST nodes, evaluator, and examples. Add strategies for good syntax errors with line/column reporting.
Explain how policy proposals are evaluated using evidence, tradeoffs, stakeholders, and measurable outcomes
Give a neutral framework for evaluating a public policy proposal: define goals, identify stakeholders, compare alternatives, assess costs/benefits, consider equity impacts, and propose metrics and timelines for evaluation. Provide a reusable checklist.
Summarize key trends shaping modern technology: AI safety, privacy, energy use, and regulation basics
Provide an accessible overview of current technology themes: responsible AI development, data privacy principles, cybersecurity hygiene, sustainability/energy considerations, and how standards/regulation generally work. Keep it non-technical and practical.
