Emergency Office Relocation Plan Under Budget and Time Constraints

You are the operations manager of a 45-person software company. Due to a sudden building safety violation, your landlord has given you exactly 10 business days to vacate your current office. You must relocate the entire company while keeping business disruption to a minimum. Here are your constraints: - Budget: $18,000 total for the move (moving company, temporary solutions, setup costs) - 10 business days to fully vacate (non-negotiable; penalties of $2,000/day after deadline) - You have already signed a lease on a new office space, but it needs 3 days of IT infrastructure setup (network cabling, server rack installation) before anyone can work there - Your company has 3 critical client deadlines falling within the 10-day window: Day 3, Day 6, and Day 9 - You have 12 developers who need dual-monitor setups and VPN access to work remotely, but only 8 company laptops available for remote work - The moving company you prefer is available only on Days 5-6 or Days 8-9 (two-day job either way) - Your server room contains 4 physical servers that require professional handling and 6 hours of downtime for migration - One team member (your IT lead) is on vacation Days 1-3 and cannot be recalled Create a detailed day-by-day relocation plan (Days 1 through 10) that addresses all of the above constraints. For each day, specify the key actions, who is responsible, and any risks. Also include a contingency plan for the most likely failure point you identify. Explain your reasoning for the sequencing choices you make.

Advanced Log File Parser for a Custom Format

Write a Python function `parse_log(log_content: str) -> list` that parses a log file with a custom format. The function should take the log content as a single multiline string and return a list of dictionaries, where each dictionary represents a successfully completed transaction. **Log Format Rules:** 1. **`START <transaction_id> <timestamp>`**: Marks the beginning of a transaction. `transaction_id` is a string without spaces. `timestamp` is an ISO 8601 formatted string. 2. **`END <transaction_id> <status> <timestamp>`**: Marks the end of a transaction. The `transaction_id` must match an open transaction. `status` is a single word (e.g., `SUCCESS`, `FAIL`). 3. **`EVENT <key1>=<value1> <key2>="<value with spaces>" ...`**: Represents an event within the current active transaction. It consists of one or more key-value pairs. Values containing spaces must be enclosed in double quotes. 4. **`COMMENT # <any text>`**: A comment line that should be ignored. **Processing Logic:** * The function should process lines sequentially. * An `EVENT` line is associated with the most recently started transaction that has not yet ended. * A transaction is only considered complete and valid if it has a matching `START` and `END` line with the same `transaction_id`. * The output should be a list of dictionaries. Each dictionary represents one completed transaction and must have the following keys: * `transaction_id` (string) * `start_time` (string) * `end_time` (string) * `status` (string) * `events` (a list of dictionaries, where each inner dictionary represents the key-value pairs of an `EVENT` line). **Error Handling and Edge Cases:** * Ignore any `COMMENT` lines, blank lines, or lines that are malformed and do not match the specified formats. * Ignore any `EVENT` that occurs outside of an active transaction (i.e., before the first `START` or after a transaction has been closed). * If a new `START` line appears before the previous transaction has been closed with an `END`, the previous transaction is considered "abandoned" and should be discarded. The new `START` line begins a new transaction. * Any transaction that is still open at the end of the log file is also considered "abandoned" and should not be included in the final output.

System Design

OpenAI GPT-5.2 VS Google Gemini 2.5 Flash

Design a URL Shortening Service

Design a URL shortening service (similar to bit.ly or tinyurl.com) that must handle the following constraints: 1. The service must support 100 million new URL shortenings per month. 2. The ratio of read (redirect) requests to write (shorten) requests is 100:1. 3. Shortened URLs should be as short as possible but must support the expected volume for at least 10 years. 4. The system must achieve 99.9% uptime availability. 5. Redirect latency must be under 50ms at the 95th percentile. 6. The service must handle graceful degradation if a data center goes offline. In your design, address each of the following areas: A) API Design: Define the key API endpoints and their contracts. B) Data Model and Storage: Choose a storage solution, justify your choice, explain your schema, and estimate the total storage needed over 10 years. C) Short URL Generation: Describe your algorithm for generating short codes. Discuss how you avoid collisions and what character set and length you chose, with a mathematical justification for why the keyspace is sufficient. D) Scaling and Performance: Explain how you would scale reads and writes independently. Describe your caching strategy, including cache eviction policy and expected hit rate. Explain how you meet the 50ms p95 latency requirement. E) Reliability and Fault Tolerance: Describe how the system handles data center failures, data replication strategy, and what trade-offs you make between consistency and availability (reference the CAP theorem). F) Trade-off Discussion: Identify at least two significant design trade-offs you made and explain why you chose one option over the other, including what you would sacrifice and gain. Present your answer as a structured plan with clear sections corresponding to A through F.
