I run an RPi 4B/8G with external USB SSD drive; I do this because my uSD
cards were getting worn out after about a year of use; I've had no such
problems with my Samsung 870 EVO nor Samsung SSD T7.
I use the built-in GigE adaptor on the RPi 4B, because it's convenient as I
have wired ethernet
I am not on the Release Team or involved except as a user --- however, I
greatly approve of _RC6 release, AND the additional time it will take for
people to beat on it before it becomes the 10.0 release.
We have more hardware to properly work on now (just for starters, all RPi
up to 4 at least),
I did a sysupgrade to amd64 to _RC5 (from _RC3), but it seems to have
reset my passwords. The accounts are there, just the passwords have been
changed.
Tried logging in single-user as described in

# passwd root

Couldn't generate salt.
I've been running ECC in the Windows box for years, it seems like a 'no

Most of the computing industry has been hell-bent on performance, yielding
impressive gains (albeit with occasional setbacks:
Hi, fresh download; /usr/src nonexistent, /usr/obj nonexistent

# ./build.sh -O ../obj tools
gives me:

TPP apparently improves 'hot' data locality with a low-overhead algorithm
that has been implemented in mainstream Linux.

I'm having no success trying to get ls to print file sizes, using the -M
flag.
-MModifies the -l and -s options, causing the sizes or block counts
reported to be separated with commas (or a locale appropriate
separator) resulting in a more readable output.
I believe the font size of the printed documentation is not specified...

Naturally, I 'should' know that "Device busy" means "hey dude! you're in

There are a bunch of files on the floppy when mounted; I delete them all;
but then, there is a large amount of 'used' space! unmounting +
remounting 'fixes' this problem.

Hi, 'dd' seems to behave different if the 'if' is /dev/random than if it is
anything else, e.g. /dev/zero:

records out65536 bytes transferred in 0.001 secs (65536000 bytes/sec)# ls

Maybe it should print "$HOME is not set" in that case?

Yes, the process for making a floppy useful to an OS is the same as any
other computer media.
The common "1.44" MB floppy is actually 2.0 MB (12 Mbits) worth of data.

write certain patterns onto the diskette; for a standard

The dd trick seems to work only if the diskette is pre-formatted.

Was looking at no-starch press, and saw these 2 books:
http://culver.net/NetBSD/no-starch.jpg
And I realized, you know, there seems to be a 'missing' book --- I see only
Absolute FreeBSD and Absolute OpenBSD.
Is there any status on a "NetBSD Book" ? Or is this pretty much it:
The last "Danger" smartphone -- some say still the very best smartphone for
its time -- used NetBSD under the hood. It was really fast and responsive,
small, easy to fit onto the processor -- all from a buddy of mine who
worked at Danger in SW. Danger did the App SW, which was also very good.
Perhaps not on-topic, but... I put the "options HZ=1000" into my RPi
config (as Alistair suggests, it's GENERIC64 plus this one extra options
line) and now
*$ sysctl kern.clockrate*
*kern.clockrate: tick = 1000, tickadj = 4, hz = 1000, profhz = 1000, stathz
= 1000*

common math/trig functions, and compares their library to glibc and Intel.
It's interesting that the
VLC on non-NetBSD machines sometimes operates this way (stuttering /
freezing) so much so that I now use AnyDVD on Windows, which seems to have
taken the VLC codebase and fixed lots of things.

I, too, have started w/GENERIC and commented out h/w I don't have; these
days, I don't bother, because we have plenty of memory & disk (relatively

Have you ever done this:
$ rm good-stuff
$ echo oh noo\!
because good-stuff is in the bitbucket of no return.
unrm exists as a shell script:
http://freshmeat.sourceforge.net/projects/unrm
But, as the commenter says, it would be great to restore filenames and
directories.
TOPS-20 had this
understand.
I guess the real question is: is something broken? For pkgsrc-wip, for a
bunch of reasons, they decided on git.
If something's not broken otherwise, why change? That's legitimate, too.

Two points:
1) As much as folks (like me, Johnny) don't like it: git is THE most
widely-used rcs in the world, by far; I consider it just a kind of
annotated tar file.
2) git complexity (and user confusion) comes about due to the lack of
conceptual integrity of the design / command structure.

As to what is 'real time' -- as you can probably tell by watching the video

Hi all, I want to hook up a sensor using iic on an RPi. Is there a
tutorial somewhere on how to do this? Do I have to compile a specific
config to enable iic because GENERIC doesn't?
I tried this:
*# i2cscan iic0
i2cscan: couldn't open iic0: Device not configured# i2cscan iic1
Hi, it's great this is fixed.
But, I do wonder: How is even possible to have something called "NetBSD
mumble STABLE ..." not compile? Because, you know, not compiling is kinda
Not Stable.
It would seem to me some automatic check isn't working -- the one that
guarantees buildability?
