These
info.host[strlen(info.host)] = '\0';
…
info.user[strlen(info.user)] = '\0';
look nonsence as zeros are placed exactly where they already are.
Should read as in following instead:

The first opportunity to write a nil byte should always be taken. Using sizeof
only means that in corner cases memory disclosure may occur between where the
nil should be and the end of the array. While this isn't a security critical
app, it is still good coding practice.
x = strlen(info.host)

I think your code is wrong. If the NUL byte is present, it doesn't do
anything, however if it is not there, strlen will read more than it
should, and possibly try to read some invalid address.
In case info.host is a fixe size array, a simple
info.host[sizeof info.host - 1] = 0;
would do.

You're absolutely correct if the length of value to be copied is not validated
prior to the copy. Then, an invalid page could be hit if no nil is present
within the array or beyond.
I wasn't providing a verbatim patch (notice the function and operator weren't
filled in). I was just providing th
Not exactly. But, functionally close enough.
I skipped commenting on strncpy to ignore the plethora of issues with lpd and
focus on the question at hand.

wrong. strncpy only copies up to the specified maximum.
the code is ugly but correct.

You get that I'm talking about the subsequent read back after copy, right? No

Also, you're making strange presumptions about me having presumptions. I'm not
trying to say you're wrong or a poor coder, Erik. I was simply offering my
point of view.

is anyone working on a xhci driver? or is anyone willing to send hardware
so someone who's willing will write a driver for it?

send me an address. how many boards do you want?

I use Supermicro 5015A-EHF-D525 1U servers in a 19" cabinet. they are
fairly quiet. you can usually find reasonably priced used 12U or 24U
cabinets at places like RE-PC.
i've not found a good way of mounting Sheeva and RPi cpu's in the cabinet.

For something low power you can use an external power brick and a "picoPSU"
DC-DC converter with 12V in and 5V + 12V out with appropriate connectors. Check
out mini-itx.com. Fanless power supplies are also available upto about 480W.
Though I don't worry about fan noise as my fileserver is not t
I bought a SuperMicro X7SLA-H a few years ago, 2 1.6Ghz Atoms with 2xGbE,
though only 2GB of RAM. This is my home auth/cpu/file server.
I am very happy with it, it does have a small fan for the glue logic chip
but the cpu is passively cooled. I have this in an mini-ITX case with a pair or
mirrored
+1 to this, though I use a different chassis.
Since I'm relegated to an apartment at the moment, I have a desktop rack
mounted in a closet. My development boards are set on top of the cabinet
with 6-32 1/2" standoffs, which rest on an ESD mat grounded to the rack.
It's small, but gives me about 8U

Hello,
OSX unicodes for some japanese letters are irregular.
current u9fs fails to handle OSX unicode correctly.
you will find u9fs that fix the problem at http://plan9.aichi-u.ac.jp/netlib/
probably anyone except japanese will not be interested in, though.

I'm looking to eliminate the 220V circuit between UPS and PSU
altogether, I believe it to be archaic and inefficient. I'm also
looking for multiple inputs, so that eventually it will be possible to
connect the PSU directly to solar panels as well
