Redox OS Doubles The Performance Of Its File-System & I/O Drivers

([Operating Systems] 4 Hours Ago Redox OS)


The Rust-written Redox OS open-source operating system is out with its monthly development summary that notes some interesting work taking place.

Redox OS is now receiving funding via the NLnet Foundation to work on Redox OS Unix-style Signals support. Redox OS also received a $13k USD donation to further work on its Termion terminal manipulation library. In June Redox OS rolled out a new default wallpaper and other updated visuals:

Most exciting I found with the June update for Redox OS was the performance achievements:

"4lDO2 doubled the RedoxFS performance by reducing the number of context switch roundtrips per block read and write.

He also applied this improvement on the SATA, NVMe, USB SCSI and VirtIO Block drivers."

Great to see and should be a big win for RedoxOS and I/O performance at large for this from-scratch Rust operating system.

Redox OS has also been working on improvements to its libc implementation, better USB and PCI driver support, and enabling more programs to run on Redox OS. For more details on these efforts, visit [1]Redox-OS.org .

Norbert Weiner was the subject of many dotty professor stories. Weiner was,
in fact, very absent minded. The following story is told about him: when they
moved from Cambridge to Newton his wife, knowing that he would be absolutely
useless on the move, packed him off to MIT while she directed the move. Since
she was certain that he would forget that they had moved and where they had
moved to, she wrote down the new address on a piece of paper, and gave it to
him. Naturally, in the course of the day, an insight occurred to him. He
reached in his pocket, found a piece of paper on which he furiously scribbled
some notes, thought it over, decided there was a fallacy in his idea, and
threw the piece of paper away. At the end of the day he went home (to the old
address in Cambridge, of course). When he got there he realized that they had
moved, that he had no idea where they had moved to, and that the piece of
paper with the address was long gone. Fortunately inspiration struck. There
was a young girl on the street and he conceived the idea of asking her where
he had moved to, saying, "Excuse me, perhaps you know me. I'm Norbert Weiner
and we've just moved. Would you know where we've moved to?" To which the
young girl replied, "Yes, Daddy, Mommy thought you would forget."
The capper to the story is that I asked his daughter (the girl in the
story) about the truth of the story, many years later. She said that it
wasn't quite true -- that he never forgot who his children were! The rest of
it, however, was pretty close to what actually happened...
