5 Common Refactors in Python for Beginners

Simplifying Boolean expressions by directly returning the condition instead of using if-else blocks
Using list comprehensions instead of for loops with if statements for constructing lists
Avoiding repeated calculations by storing the result of a function call in a variable
Replacing loops with built-in functions like map() and filter() for more efficient and concise code
Combining multiple if statements with logical operators for clearer and less redundant code

Meitu, dubbed China’s MicroStrategy, liquidates entire Bitcoin and Ethereum holdings: Asia Express

Meitu, dubbed as China’s MicroStrategy, has liquidated its entire holdings of 940 Bitcoins and 31,000 Ethereums.
The move has sparked speculation about the reasons behind this decision, as South Korea considers legalizing corporate crypto buying.
Meitu's decision seems to be based on corporate specifications and allocation strategies rather than a reflection of Bitcoin's value.
While Meitu's sell-off may not signify the end of cryptocurrencies, it remains uncertain if other major companies will follow suit.

Technical Bias: The Invisible Force Shaping Our Architecture Decisions

Our cognitive biases often shape our architectural decisions, often at the expense of practical solutions.
Biases lead to the dismissal of potential solutions that don't align with technology preferences, resulting in technical debt.
The three pillars of technical prejudice are the stack comfort trap, the innovation fallacy, and the echo chamber effect.
To break the cycle, technical directors should measure impact, challenge default choices, and implement requirements for architectural decisions.

Privacy vs Anonymity: Why You’re Doing It All Wrong

Privacy tools don't make you anonymous, most people misunderstand this.
Privacy is about controlling who sees your data, not hiding everything.
Anonymity is different from privacy, but most people need privacy, not anonymity.
Modern CSS tracking and browser fingerprinting pose a threat to privacy.

🔮 Fabricating your future

Marketing strategies in 2025 will focus on personal points of view and unique experiences.
AI can be creatively efficient, but training it on past human-written content for brand voice is essential.
Expand beyond SEO to email marketing for traffic control.
Incorporate relatable stories and problem-solving oriented marketing copy, including negative critiques.
2025 web design trends predict playful and interactive websites, anti-design, sustainable web design, and voice search.
Returning to design fundamentals, authentic imperfections, and less reliance on trending tools are becoming popular.
Achieving creative goals can be done by learning new skills, setting intentions over specific goals, curbing burnout, having a dedicated workspace and sticking to a consistent work schedule.

What `kotlin.coroutines.Continuation` is

kotlin.coroutines.Continuation is the low-level mechanism by which suspending functions pause and resume their execution.
When a coroutine suspends, it saves a Continuation that knows how to get everything going again.
Most developers seldom write code that directly manipulates Continuation objects. They use high-level constructs like suspend functions, coroutineScope, withContext, async, or await.
kotlin.coroutines.Continuation encapsulates the suspended state, links to the coroutine’s context, and provides a method to continue execution with a final result or error.

This week experience

This week experience: My second week in practicing data structure problems.
Solved three linked list related problems: Intersection of two linked lists, Remove nth node from end of list, and Reverse nodes in k-group.
Intersection of two linked lists can be solved using two pointers to determine if they meet at a common node.
Remove nth node from end of list can be achieved by using two pointers, fast and slow, to find the node just before the nth node.
Reverse nodes in k-group involves creating a dummy node and iterating to find the kth node, then reversing the linked list in groups.
Experience and practice are key in improving problem-solving skills.

Database Performance Strategies

Database performance is influenced by several critical factors including item properties, operational factors, scale factors, and availability.
Different workload types create unique challenges for database performance, including write-heavy, read-heavy, delete-heavy, and mixed workloads.
Denormalization is a strategy to improve read performance by reducing the number of table joins needed.
Database locking process ensures data consistency during concurrent operations by managing lock acquisition and lock management.
Replication architecture provides scalability and reliability through leader and follower nodes.
Sharding strategy distributes data across multiple databases using shard router and individual shards.
Database indexing optimizes data retrieval using B-Tree structure and index management.
Practical implementation considerations include performance monitoring, optimization selection, trade-off analysis, and future planning.
