• GNU assembler print expression instead of string (stackoverflow.com):

  in #gas printing #asm debug messages with .print works better with .altmacro syntax because you can %expr when normally .print only accepts literal strings

• Show macro expansions in GNU assembler as listing preprocess only (stackoverflow.com):

  #gas -alm shows a full recursive trace of expansion of #asm #macros, which is handy for debugging them, as well as a full listing of the machine code emitted

• Intrinsics viewer (dzaima.github.io):

  #RISC-V #vectorization intrinsics search

• (synit.org):

  #tonyg has written #Synit, a reactive OS with #object-capability discipline, but using the Linux kernel, built on the language he developed for his dissertation, Syndicate. #operating-systems

• On Microchip AT86RF215 radios (wirelesspi.com):

  #SDR with the Microchip #AT86RF215 transceiver, which surprisingly can provide 13-bit LVDS #radio I/Q samples from its digital frontend. The transmitter is direct-upconversion with up to 1 MHz bandwidth and the receiver is 32Msps downsampled to 4Msps. #hardware

• (digikey.com):

  Digi-Key has 813 #AT86RF215 transceiver chips in stock for US$7.08. #SDR #hardware

• Cascaded integrator comb CIC filters a staircase of DSP (wirelesspi.com):

  extensive discussion of #DSP #Hogenauer #CIC #filters

• Dril Twitter interview profile identity (theringer.com):

  #dril of #Twitter (and originally "gigantic drill" on #Something-Awful) is Paul Dochney

• Oopscode (people.idsia.ch):

  very unusual #C formatting style (and a very interesting algorithm as well)

• Structured gas (github.com):

  #gas nested control-flow #asm #macros: _if, _else, _elseif, _endif, using .altmacro

• Macro (sourceware.org):

  #documentation for #gas #asm #macros, including an example that counts

• L gas NASM (web.archive.org):

  comparison of #gas and #NASM #macros from 02007; malicious JS blanks the page after loading but can be defeated with Firefox readability button. #asm
