Cracking DSA with Real-World Analogies: Because Code Shouldn’t Feel Like Math Class
- Data Structures and Algorithms (DSA) can feel like a cryptic temple language.
- However, by associating DSA concepts with everyday things, it becomes easier to understand and apply.
- Analogies, such as a stack of plates at a buffet representing the Last In, First Out (LIFO) concept, can be helpful.
- Other analogies include a queue at a movie theater representing the First In, First Out (FIFO) concept, and a HashMap in action as a key-value pair lookup.

Avoiding Costly Mistakes with Uncertainty Quantification for Algorithmic Home Valuations
- Automated Valuation Models (AVMs) use AI to predict home values based on past property transactions, but these predictions come with uncertainty that can lead to costly mistakes.
- AVMU methodology helps quantify the reliability of AVM predictions by providing uncertainty estimates.
- AVMU involves generating out-of-fold price predictions, calculating absolute deviations, training an uncertainty model, and estimating uncertainty for price predictions.
- Uncertainty quantification helps buyers make informed decisions by identifying the reliability of AVM predictions.
- AVMU is crucial in scenarios where AVM predictions lack comparable data, ensuring buyers do not overpay or undervalue properties.
- Training an uncertainty model involves optimizing loss functions suited for ranking and identifying prediction uncertainties.
- AVMU can be applied beyond home valuations to assets like cars or collectibles, enhancing decision-making processes.
- Despite its versatility, AVMU is not foolproof and cannot eliminate all uncertainties, particularly those arising from unpredictable market factors.
- AVMU provides probabilities rather than fixed truths, guiding buyers to manage uncertainty and make informed choices when purchasing properties.
- AVMU methodology offers a valuable tool in understanding and navigating uncertainty in algorithmic home valuations to prevent costly mistakes.

How to Optimize your Python Program for Slowness
- The article explores how to make Python programs run absurdly slower by examining different rule sets and building small Python programs to run for an extraordinarily long time.
- Starting with the most permissive rule set of allowing infinite loops, the article demonstrates a simple program using 'while True' that runs forever.
- Moving on to rule set 2, the article introduces nested fixed-range loops to run for an impractically long time with a small amount of memory usage.
- Rule set 3 introduces a 5-state Turing machine with infinite, zero-initialized memory, running for 47,176,870 steps before halting.
- The article progresses to a 6-state Turing machine known to run for over 10^↑↑15 steps, showing a video of its first 10 trillion steps.
- Rule set 5 delves into building a Python program to compute 10^↑↑15 steps using increment, addition, multiplication, exponentiation, and tetration functions.
- The article emphasizes the impact of Python's immutable int type on performance, advocating the use of gmpy2.xmpz for in-place updates.
- By constructing these programs, the article highlights the capabilities of nested loops, Turing machines, and hand-inlined functions to demonstrate incredibly slow program runtimes.
- The exploration of tetration unveils a hierarchy of hyperoperations beyond exponentiation, showcasing the potential to express unimaginably large numbers compactly.
- The article concludes by providing insights on writing programs that run for an extensive duration, showcasing the importance of efficient coding practices and minimal systems.
- The author invites readers to explore the open-source GitHub repository for all the code discussed in the article.

CSS Transitions Made Easy
- CSS transitions enable smooth changes between different states of an element's style.
- Transitions occur when a property's value changes and CSS interpolates the difference over a specified duration.
- The transition property controls what changes, how long it takes, and how it feels.
- Only animatable properties with numeric or calculable values can be transitioned.
