Design a Global URL Shortening Service

Design a public URL shortening service similar to Bitly. Users can submit a long URL and receive a short alias, then anyone can use the short link to be redirected to the original URL. Your design should support these requirements and constraints: Functional requirements: - Create short links for arbitrary valid URLs. - Redirect short links with low latency. - Support optional custom aliases when available. - Provide basic click analytics per link: total clicks, clicks in the last 24 hours, and top 5 countries by click count. - Allow link expiration dates. Scale assumptions: - 120 million new short links per day. - 8 billion redirect requests per day. - Read-heavy workload with strong traffic skew: a small fraction of links receive very high traffic. - Global users across North America, Europe, and Asia. Constraints: - 99.99% availability target for redirects. - P95 redirect latency under 80 ms for users in major regions. - Newly created links should become usable within 2 seconds globally. - Analytics can be eventually consistent, but redirects must be correct. - Budget matters: justify where you would spend on stronger consistency or multi-region replication and where you would avoid it. - Assume no third-party managed analytics product; design the core system yourself. Please provide: - A high-level architecture with major components and data flow. - Storage choices for link mappings, analytics events, and cached hot links. - ID generation or alias strategy, including collision handling and custom alias checks. - API design for create-link, redirect, and analytics retrieval. - Scaling approach for hot keys, caching, partitioning, and multi-region traffic. - Reliability strategy covering failover, data replication, backup, and degradation behavior. - Key trade-offs and at least two alternative design choices you considered and rejected.

Low-Cost Ideas to Reduce Food Waste in a Small Apartment

A household of two adults lives in a small apartment with a tiny refrigerator, little storage space, and a busy work schedule. They throw away too much food because produce spoils, leftovers are forgotten, and meal plans change unexpectedly. They want practical ideas they can start this month. Brainstorm 20 distinct ideas to reduce their food waste under these constraints: - Total new spending this month should stay under 50 US dollars. - No idea may require buying major appliances or renovating the apartment. - At least 5 ideas must focus on shopping and planning. - At least 5 ideas must focus on storage and visibility. - At least 5 ideas must focus on cooking, leftovers, or using ingredients flexibly. - The remaining ideas can be any other relevant category. - Include a one-sentence explanation for each idea. - For each idea, add a rough cost label from this set only: free, low, or moderate. - Avoid repeating the same idea in slightly different wording. Organize the answer as a clear bullet list grouped by category.

The Four-Day Work Week: A Productivity Panacea or a Logistical Nightmare?

The concept of a standard four-day work week, with no reduction in pay, is gaining traction globally. Proponents argue that it enhances employee well-being, boosts focus and productivity, and can even be good for the environment. Critics, however, warn that it is not a one-size-fits-all solution, potentially leading to employee burnout on longer workdays, creating coverage gaps for businesses, and being impractical for many essential industries. Should companies and governments actively promote the transition to a four-day work week as the new standard?

The Four-Day Work Week: A Revolution in Productivity or an Economic Risk?

This debate centers on the proposal to make a four-day work week the standard for full-time employment, without a corresponding reduction in pay. Advocates claim this model enhances employee well-being, increases focus and productivity, and can even reduce business overheads. Critics, however, argue that it is not a viable model for all industries, could place an unsustainable burden on small businesses, and may ultimately harm a nation's economic competitiveness.

Implement a Versioned Key-Value Store with Historical Queries

Write code that implements an in-memory versioned key-value store supporting historical reads. The store begins empty and processes a sequence of commands. Each successful mutating command creates exactly one new global version number, starting from 1. Read-only commands must not create a version. Keys and values are case-sensitive strings without spaces. Versions are positive integers. Commands: SET key value Create or overwrite key with value. DELETE key Remove key if it exists. GET key Return the current value for key, or NULL if the key does not exist. GET_VERSION key version Return the value associated with key immediately after the specified global version was created, or NULL if the key did not exist at that version. If version is greater than the latest existing version, treat it as invalid and return INVALID_VERSION. HISTORY key Return all historical states for the key in increasing version order, including deletions, formatted as version:value pairs separated by commas. Use NULL for deleted or absent-after-mutation states. If the key has never been affected by any mutating command, return EMPTY. Input format: The first line contains an integer N, the number of commands. The next N lines each contain one command. Output format: For every GET, GET_VERSION, and HISTORY command, print one line with the result. Behavior details and edge cases: - Every SET always creates a new version, even if the value is unchanged. - Every DELETE always creates a new version, even if the key does not exist. - Versions are global across all keys, not per key. - HISTORY for a key should include only versions where that key was directly affected by SET or DELETE. - If a key was deleted and later set again, both events must appear in HISTORY. - Efficiency matters: assume up to 200000 commands, with many historical queries. Your solution should read from standard input and write to standard output. Include the full working program in one file. You may use any mainstream programming language, but the code should be complete and executable as written.

Customer Support Reply as a Calm Travel Agent

You are roleplaying as Maya, an experienced travel agent known for being calm, practical, and empathetic. Reply to the customer message below in character. Customer message: "Hi. I'm really frustrated. My flight to Barcelona is tomorrow morning, and I just got an email saying the airline changed it to a flight six hours later. That means I'll miss the first day of a conference I'm speaking at. I booked everything through your agency because I wanted this handled smoothly. I don't want a generic apology. I need to know what my options are right now, whether I can be moved to another flight, and what happens to the hotel transfer I already prepaid. Please give me a clear answer fast." Write a single reply that sounds like Maya. It should acknowledge the customer's frustration, explain realistic next steps, avoid making promises you cannot verify, and be genuinely useful. Do not mention being an AI or invent access to live airline systems. The reply should read like a real customer support message sent right now.

Design a Real-Time Ride-Sharing Notification System

You are tasked with designing the high-level architecture for a notification system for a popular ride-sharing application. The system must be able to handle 1 million daily active users and an average of 500,000 rides per day, with peaks during rush hours. The system needs to deliver the following types of notifications: 1. Driver has been assigned. 2. Driver is arriving soon (e.g., 2 minutes away). 3. Ride has been completed and receipt is available. 4. Promotional messages targeted to users in specific geographic areas. Your design proposal should address the following points: - A high-level architectural description of the components and their interactions. - Key technology choices (e.g., for message queuing, databases, push notification services) and justification for your choices. - A strategy for ensuring low latency (under 2 seconds delivery time) and high reliability (at-least-once delivery). - How the system would scale to handle peak loads. - A discussion of the major trade-offs you made in your design (e.g., cost vs. performance, consistency vs. availability).

Implement a Dependency Resolver in Python

You are tasked with creating a dependency resolver for a simple package management system. Write a Python function `resolve_dependencies(package_definitions, target_package)` that determines the correct installation order for a given package and its dependencies. The `package_definitions` argument is a list of strings. Each string defines a package and its direct dependencies in the format: `'PackageName: Dep1, Dep2, ...'`. If a package has no dependencies, the format is `'PackageName:'`. Your function should: 1. Parse the input strings to build a dependency graph. 2. Given a `target_package`, find all its dependencies (including transitive ones). 3. Return a single list of strings representing the installation order. This list must be topologically sorted (a dependency must always appear before the package that depends on it). The `target_package` itself should be the last item in the list. The list should not contain duplicates. 4. Detect circular dependencies. If a cycle is found, raise a `ValueError` with a message that clearly indicates the cycle (e.g., 'Circular dependency detected involving: A -> B -> A'). 5. Detect missing packages. If a package lists a dependency that is not defined in `package_definitions`, raise a `ValueError` with a message like 'Missing package definition for: C'.

Choose the Best Strategy to Reduce City Traffic Quickly

A city has budget to fund only one transportation policy for the next 18 months. Officials want the option that is most likely to reduce weekday traffic congestion quickly without causing major public backlash. Here are the three proposals: Option A: Add two new downtown parking garages - Estimated cost: high - Time to implement: 16 months - Expected effect: makes parking easier for drivers - Risk: may encourage more people to drive into downtown Option B: Create dedicated bus lanes on four major corridors - Estimated cost: medium - Time to implement: 9 months - Expected effect: buses become faster and more reliable - Risk: removes one car lane on each corridor, which may initially frustrate drivers Option C: Lower public transit fares by 50 percent for 18 months - Estimated cost: medium-high - Time to implement: 2 months - Expected effect: transit becomes more affordable - Risk: service may become crowded if ridership rises and frequency does not improve Additional facts: - Current congestion is worst during weekday rush hours into and out of downtown. - 62 percent of downtown commuters currently drive alone. - Buses are often delayed because they share lanes with cars. - A recent survey found that residents support faster public transit, but strongly oppose policies seen as making driving easier at public expense. - The city cannot expand the total transit operating budget beyond what is already committed, except for the chosen policy itself. Write an analysis recommending one option. Compare all three options, weigh tradeoffs, and explain why your recommendation best fits the city’s stated goal.
