Dictionaries in Python

Python dictionaries are a built-in data type that stores key-value pairs for efficient data retrieval.
dict() and {} can create dictionaries in Python. Use {} for concise syntax and dict() for dynamic creation from iterable objects.
.__dict__ is a special attribute in Python that holds an object’s writable attributes in a dictionary.
Python dict is implemented as a hashmap for fast key lookups.
Dictionaries in Python are mutable, dynamic, efficient, and ordered.
The keys of a dictionary need to be hashable and unique, and values can be of any Python type, including other dictionaries.
Dictionaries come in handy when processing CSV and JSON files, working with databases, loading configuration files, and more.
It’s important to note that dictionaries are collections of pairs. You need to insert a key with its corresponding value.
Python’s dictionaries are a fundamental part of Python and used in core concepts like scopes and namespaces.
Dictionaries in Python have many characteristics like being dynamic, mutable, efficient, and ordered.

ClickHouse — optimizing bulk inserts for partitioned tables

High cardinality partitions can be useful for achieving fast, deduplicated reads and improving query performance.
Inserting data into highly-partitioned tables can be complex and result in a large number of parts.
Inserting data in order of the partition key can mitigate the issue of a large number of parts.
Another approach is to insert records into an unpartitioned table first and then insert them into the partitioned table.

An overview of product platforms

Product platforms are becoming increasingly important for creating scalable product ecosystems and shortening time-to-market and reducing cost. They act as a shared set of technologies, components, and procedures that enable related product development.
Platforms can offer key benefits such as improved user experience, supporting ecosystems, and scalability, and rely on three core characteristics such as shared technologies, modularity, and ecosystem-enabling features.
Successful companies that use product platforms include Microsoft Azure, Amazon Web Services, and Apple’s iOS platform, which provide scalable cloud solutions, a range of cloud-based services, consistent user experience and functionality, and clear rules, APIs, and tools to help developers create and distribute programs.
Given the many benefits of product platforms, managing them can be a challenge involving maintaining consistency, balancing flexibility with control, ensuring platform security, and managing technical debt.
Solutions to effective product platform management include creating clear API standards and design guidelines, regular platform evaluations, promoting collaboration, continuous code refactoring, and establishing a robust testing and quality assurance methodology.

Animate hero elements with scroll-driven CSS animations

GitHub's landing page features a well-designed centered hero design with a sign-up box that fades away while moving behind the code editor once scrolled down.
Using position:sticky property, the hero box can be placed inside a container and make it stick somewhere when the user scrolls around.
The hero box element should slide under the other elements to create the effect, to create new stacking context, isolation CSS property can be used.
Scroll-driven animations allow to use the CSS Animations API to add scroll animation behavior and it provides a massive performance boost compared to thousands of firing scroll handlers.
To enable scroll-driven animations, there are two new timelines: scroll progress (animation-timeline: scroll()) and view progress (animation-timeline: view()) timelines.
An animation timeline specifies the timeline used to control the progress of a CSS keyframe animation. animation-range enables us to define the start and end of our scroll-driven animation.
To make the animation visible while the text is sticky, we can control the animation depending on the view progress of another element with a named view progress timeline.
Using modern CSS paired with progressive enhancement, we can give users the best experience if their browsers support it.
If you want to learn more about scroll-driven animations, Bramus from the Chrome DevRel team maintains scroll-driven-animations.style.
Scroll-driven animations provide a fantastic performance and an exciting feature that is being developed for future web authors and developers.

Golden hospital gowns

There is no direct connection between AI and cryptocurrency, but they both have a similar vibe.
The metaphor of a golden hospital gown is proposed to represent things that are a mixture of good and bad, with both haters and fanboys.
AI's ability to create images from text descriptions is amazing, but there is a strong temptation to settle for mediocre and vaguely creepy images.
The post titled 'Golden hospital gowns' appeared on John D. Cook.

Understanding Without Collecting: Building a Privacy-First Context Service

Traditional context analysis knows everything about someone, but a privacy-focused Context Service aims to understand context with respect to boundaries.
Organizing the code proved to be a major victory in the development process, saving time on debugging.
Integrating BERT for context understanding presented a significant hurdle, but model management helped overcome the challenges.
Privacy filters were implemented to protect privacy by not storing raw context data and instead focusing on preserving privacy.
