Erlang in 100 Seconds - YouTube (www.youtube.com)

Concurrency functional programming message passing fault tolerance Erlang programming Ericsson BEAM

Erlang, a functional, fault-tolerant programming language, was designed at Ericsson in 1986 for large-scale concurrent systems. Its development was propelled by the need to enhance telecommunications infrastructure, leading to the creation of the BEAM virtual machine. Erlang’s unique programming model enables efficient handling of millions of concurrent processes with minimal overhead, ensuring system resilience through process isolation and hot code swapping. Today, Erlang continues to underpin modern languages and systems, demonstrating significant influence in the programming community.
Main Points
- Fault ToleranceErlang is known for its fault tolerance, facilitated through process isolation and a philosophy of allowing individual processes to fail without impacting the whole.
- BEAM Virtual Machine ImportanceErlang's BEAM virtual machine allows for millions of concurrent processes with low overhead, and is still in use by modern languages like Elixir.
- Message Passing ModelErlang's programming model, which emphasizes message passing, is critical for its ability to handle billions of messages daily across various platforms.

Tiny bitfield based text renderer (www.onirom.fr)

x86 text renderer bitfield compression programming computer graphics

The article explores the development and optimizations of a tiny bitfield based text renderer capable of rendering with fewer bytes of x86 code, highlighting its efficiency, examples of bitfield packing for data compression, and its practical applications in intros.
Main Points
- Initial non-bitfield x86 codeThe author wrote specific x86 code which resulted in about 69 bytes to render a "ORZ" string with a custom tiny typeface. This initial implementation did not use bitfield but was a reference for evaluating generic algorithms later.
- Optimized x86 conversionA x86 handwritten conversion of the best C algorithm resulted in 52 bytes of x86 code, which is smaller than the first non-generic one, demonstrating competitiveness of handwritten optimizations.
- Bitfields for data packingBitfields allow packing data compactly, with 9-bit required to encode a glyph in a 3x3 font, showcasing the method's space efficiency.
- Practical example in intro demoA demo by Baudsurfer / RSI called Centurio, packed the logo in a single 32-bit value showcasing practical use of bitfields in intros.
