1. AMD’s Turin: 5th Gen EPYC Launched Total comment counts : 16 Summary The article discusses hands-on experiences with the AMD EPYC 9575F processor, focusing specifically on its memory subsystem enhancements. It highlights the impressive memory bandwidth capabilities of the 9575F—around 52 GB/s for reads and 48 GB/s for writes—compared to desktop counterparts, largely due to its dual GMI links to the I/O die. The processor supports up to 12 channels of DDR5 memory at varying speeds, commonly up to 6000 MT/s in most systems....

1. A Lisp compiler to RISC-V written in Lisp Total comment counts : 12 Summary The article discusses a simple experimental Lisp compiler written in uLisp that compiles Lisp functions into RISC-V machine code. It can be run on RISC-V cores like those in the Raspberry Pi Pico 2, building on an earlier project that compiled Lisp to ARM. The compiler is based on the structured nature of Lisp, removing the need for separate tokenizing or parsing, and is compatible with Common Lisp for displaying generated code, albeit not for execution....

1. John Carmack on inlined code (2014) Total comment counts : 37 Summary In a comment dated September 26, 2014, John Carmack reflects on an email he sent in 2007 discussing coding practices, particularly focusing on inlining code and its implications for software reliability. Initially skeptical about pure functional programming, he has since recognized its benefits in reducing unexpected dependencies and state mutations. He emphasizes that while inlining can expose the complexity of state changes, it encourages better coding practices, pushing programmers to refactor impure code into pure functions....

1. Nobel Prize in Physics awarded to John Hopfield and Geoffrey Hinton [pdf] Total comment counts : 128 Summary error Top 1 Comment Summary The article discusses the surprising nature of recent Nobel Prize winners in Physics, highlighting a trend where winners are not widely recognized even within their subfields. It specifically mentions the 2016 winners Kosterlitz, Thouless, and Haldane as deserving, despite not being household names. A point of contention is the inclusion of Geoffrey Hinton, who has minimal experience in physics, whose contributions are deemed unsuitable for a physics prize....

1. Can you get root with only a cigarette lighter? Total comment counts : 31 Summary In his article, David Buchanan discusses the creative process of hardware fault injection (HFI), a technique used for exploiting software vulnerabilities when bugs are scarce. He explains various forms of fault injection—including electromagnetic pulses and glitches—and acknowledges that traditional HFI often requires expensive specialized equipment. However, Buchanan highlights affordable alternatives, such as using an RP2040-based device and even a piezo-electric BBQ igniter for electromagnetic fault injection....

1. Why does man print “gimme gimme gimme” at 00:30? (2017) Total comment counts : 37 Summary The article discusses an amusing issue related to the man command, specifically an easter egg that outputs “gimme gimme gimme” (a reference to an ABBA song) when run without arguments at 00:30. This easter egg was added playfully by developer Colin Watson six years ago but began causing unexpected failures in automated tests. After reflection, Watson decided to remove the easter egg in the upcoming man-db 2....

1. Terminal colours are tricky Total comment counts : 46 Summary The article discusses common challenges and solutions related to terminal color schemes. The author reflects on their long journey to find a satisfactory color scheme and gathers feedback from users on Mastodon. A major complaint highlighted is the difficulty of reading certain colors, such as “blue on black.” The author explains that terminals use ANSI colors (16 basic colors) but that there is a lack of standardization across terminal emulators, leading to inconsistencies in color appearance....
