Before the advent of user-friendly programming, software development was complex and limited to those proficient in machine codes and low-level instructions. Grace Hopper envisioned a simpler approach where programming could be done in plain English. This perspective revolutionized human-computer interaction, making programming more accessible. While Corrado Böhm theoretically developed the first compiler in 1951, it was Hopper's practical implementation in 1952 that made a significant impact. Her creation of the A-0 System, the first practical compiler, allowed

Researchers have discovered a new type of magnet called "altermagnets," which represents the first significant advancement in magnetism in nearly a century. Inspired by artwork, Libor Šmejkal, a key figure behind this discovery, proposed the existence of altermagnets in 2022, challenging the long-standing belief that only two types of magnetism existed. These new magnets have potential applications in developing a new type of computer, offering the possibility of faster performance, reduced energy consumption, and

Abiodun Olowode's article discusses two advanced Just-In-Time (JIT) compilers for Ruby: TruffleRuby and JRuby, including their advantages and disadvantages, along with a mention of the newly announced ZJIT compiler. The post explains JIT compilation as a hybrid of code interpretation and traditional compilation, highlighting how it optimizes performance by converting frequently executed code ("hotspots") into machine code during runtime. While JIT compilation allows for an initial slower performance that improves over time

Today marks the sixth anniversary of the public announcement of Project Gemini. The year has been relatively quiet, with no updates during two significant "Apollo days." The author expresses disappointment in not providing updates but reassures that there are plans to finalize minor specification issues. While previous announcements included growth statistics for Geminispace, this will no longer continue as growth was never the main goal of the project. Despite the author's inactivity, the community remains active, contributing valuable patches and translations for the documentation. The author expresses

GPUHammer is a groundbreaking attack developed by researchers from the University of Toronto, capable of demonstrating Rowhammer bit flips in GPU memory, specifically within GDDR6 on an NVIDIA A6000 GPU. This attack can manipulate data across all tested DRAM banks, bypassing existing in-DRAM defenses like Timing Row Refresh (TRR), through user-level CUDA code. A proof-of-concept example shows that by inducing a single bit flip, malicious users can severely degrade the performance of deep neural network (

A new breakout group focused on Lifetime Safety in Clang is being established following a recent LLVM Memory Safety Working Group meeting. This group aims to facilitate coordination of ongoing projects, discuss future plans, and engage more contributors in the development of a new lifetime analysis for Clang. The analysis is designed to identify issues such as use-after-scope and returning pointers to stack memory, utilizing an alias-based approach inspired by Rust’s borrow checker. The initial focus is on intra-procedural analysis for C++ raw

The author shares a useful technique for improving coding efficiency and accuracy, which involves mentally verifying that the code will perform as intended while writing it. Although this approach, referred to as "sketching a proof," may seem simple, it requires practice to execute without disrupting one’s workflow. Mastering this skill can lead to more successful code execution on the first or second attempt, creating a sense of accomplishment. The article briefly introduces the concept of monotonicity, derived from mathematics, but applied to coding

The text discusses an optimization made during the implementation of a Cuckoo Filter in C#. The author initially created a straightforward hash table using an array-like structure with 8-bit fingerprints stored in 4-byte buckets, yielding a false-positive rate of around 3%. However, they realized these 4 bytes could be treated as a single 32-bit integer, prompting an experiment to improve lookup performance. Although not pursuing ultra-low latency, the author refactored the code to use a 32-bit
