SQLite JSON at Full Index Speed Using Generated Columns from dbpro.app
234 by upmostly 6h ago | | |

Article: 7 min

The article discusses an innovative method for utilizing SQLite's JSON functions and operators by storing raw JSON documents, generating virtual columns using json_extract, indexing these columns for fast querying, and adding new columns as needed without data migration or schema rewrite.

This method offers a flexible and efficient way to work with JSON data in SQLite, potentially improving the performance of applications that rely on JSON storage.

Flexibility in indexing without upfront choices
Instantaneous computation of virtual columns
Schemaless data with relational database performance

Discussion (81): 5 min

The comment thread discusses SQLite's capabilities in handling JSON data, specifically focusing on the use of index on expression and views for performance optimization. There is also a desire for Postgres-style gin indexing to improve query speed with JSON data.

Generated columns are pretty great, but what I would really love is a Postgres-style gin index

4 billion if statements (2023) from andreasjhkarlsson.github.io
458 by damethos 6d ago | | |

Article: 29 min

The article discusses an unconventional method for determining if a number is even or odd using multiple 'if' statements instead of arithmetic operations. The author explores this concept across different bitwidths and programming languages, ultimately implementing the solution in assembly language to create a large binary file containing all comparisons needed for 32-bit numbers.

Educational value in understanding different programming paradigms; may inspire creative problem-solving approaches

Explores the concept across 8-bit, 16-bit, and 32-bit bitwidths.
Implementation in C, Python, and x86-64 assembly language.

Quality:
The article provides a detailed exploration of the unconventional method, backed by code examples and performance analysis.

Discussion (137): 13 min

The discussion revolves around optimizing a simple program to determine if a given number is odd or even. Participants debate various methods for improving performance, including replacing `if` statements with more efficient constructs like a switch statement or generating the assembly code dynamically. The conversation includes humor and sarcasm, as well as praise for the original author's work.

If statements can be replaced with more efficient constructs
Generating the code on the fly could improve performance

Article: 5 min

Fedora is an open-source repository software designed for long-term digital preservation, supporting various institutions in managing and preserving their digital collections. It offers flexibility, standards-based architecture, and a global user community.

Enables institutions to maintain and access their digital collections, potentially enhancing research, education, and cultural heritage preservation.

Flexible and standards-based system
Supports any type of digital object
Adopts globally accepted web conventions
Sustainable open-source community

Discussion (38): 3 min

The comment thread discusses the Flexible Extensible Digital Object Repository Architecture (FEDORA) at Cornell University and its relation to Red Hat's Fedora Linux. The discussion includes historical context, trademark ownership, co-existence agreements, and transparency issues between Cornell-UVA and Red Hat. There is also a mention of RIT's contributions to open-source projects related to FEDORA.

The repository is about FEDORA, not Red Hat
Red Hat and Cornell-UVA have a co-existence agreement regarding 'Fedora' name
