Re: [9fans] go under plan9 on the radpberry pi?

[hiro]

yeah, but check small blocksize random read/write vs. AoE or 9p over
ethernet. I'm not sure how efficient usb3 in terms of latency :)

good point, but is the attention that go gets now also crippling plan9? :)

Thank you. I used this snapshot and I built alef. But I couldn't build
tests. And can't build any alef program.

I think, than linker can't find /$object/lib/alef path (386 in my case)

[9fans] I went down a Forth rabbit hole and found Glenda

[Skip Tavakkolian]

So...

I have had a couple of STM32F103C8T6 "bluepill" boards laying around for a
few years and decided to do something with them.

After some uninteresting attempts with Arduino, I found Mecrisp-Stellaris
Forth (http://mecrisp.sourceforge.net/) which works great.

This lead me to wonder if there are any 9P implementations in Forth (surely
not?)
Yes! there is one by iru (https://github.com/iru-/9p4).

Then I thought about the impossible: a 9p file server in mecrisp forth. I
discovered someone had already done exactly that:
https://hub.darcs.net/pointfree/ForthFS

Re: [9fans] building Alef language

[Phil Kulin]

Problem probably in sys/src/alef/lib/rt/ near librt.8.a
Build process passes with warning about file existing

Manual command:
ar vu /386/lib/alef/libA.a sys/src/alef/lib/386/*.8
reduces number of error messages when test builds

There are only:
ALEFassert: undefined: write
ALEFassert: undefined: read

Re: [9fans] building Alef language

[Phil Kulin]

Ok. 9front doesn't have write and read syscalls. I patched
sys/src/alef/lib/sys/mkfile I translated _write to write and _read to
read. Yes, dirty hack. But I don't understand pwrite and pread
syscalls internals.

ItT'S WORK!!!

I'm worried I can't fix sys/src/alef/lib/rt/mkfile
I patch libA.a manually every time

wth. they are the same plus an offset, which you can set to -1LL to
replicate the behavior of read(2) (/sys/src/libc/9sys/read.c)

Re: [9fans] go under plan9 on the radpberry pi?

[Bakul Shah]

See https://www.flexense.com/usb3_vs_sata_disk_performance_comparison.html
Here local SATA3 vs USB3 comparison is done. While not directly comparable,
the only case where throughput is below what you can push through GbE is
single threaded small file copying. For every other case tested, GbE will
be the bottleneck.
