The drive replies SCSI error condition 2 3A 00, which means
that it does not see the CD-R.

The GUI programs often inspect the drive and medium situation by
means of the kernel or userspace device management.
Quite a lot of software layers is involved then.

But if the drive says that there is no disc in it, the urge by
Brasero is well understandable but also futile.

It got this info from the drive (which seems willing but inapt).

The good news is that the media are probably still usable
after the failure. (No traces of an attempt to prepare writing
of data to them.)

Bad news is that you will probably have to get a new burner.


Have a nice day :)

There are actuall quite a few (available or soonish available)
free CPUs. Starting from the lower end:

* Parallax Propeller [1], [2]
  Fast-ish, risc-y, 32 bit 8 core microcontroller. Design (incl VHDL)
  is under GPLV3 (no less!). You can really buy silicon for that!
  Eight (take or give) dollars and one is yours.

* OpenRISC [3]
  32 bit (these days 64 bit). LGPL. There are a few FPGA based
  implementations and some specialist "real silicon" implementations,
  AFAIK one on board of ISS. No idea whether one can buy "real
  silicon" (at least as mere mortal).

* RISC-V [4]
  To me, this is the most exciting of the pack. Modern 64 bit design,
  BSD license, actually a meta-design. There are real "biggies" behind
  that, David Patterson (of Hennessy and Patterson fame). There is an
  effort underway [5] to touch "real silicon", surrounded by a low cost
  devel board. They are pretty advanced on that and backed by people
  who seem to know their stuff, like Robert Mullins of Raspberry Pi
  fame or Bunnie Huang (need I introduce this one?).

If you follow the links you'll quickly realize that this list is far
from exhaustive. I didn't name the MIPSen and SPARCsen gone or donated
into public domain.

Ask and you shall be given :-)

It is certainly true of the net-install disk.  That is the problem sometimes.

rpcbind-0.23 & Jessie

[Saša Janiška]

Hello,

I put a fresh Jessie on the netbook of my wife's friend. She had some
ancient Linux Mint and now it is going to be her first experience with
Debian...everything is fine except the problem with rpcbind-0.21 which
is visible during the boot (first-time experience) and explained here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=748074

I do run Sid and the problem is fixed there as well as in testing, but I
do not see it in backports.

What do you advise in regard?

By looking at package's deps, I'm not sure that installing from testing
is smart move considering we want to have stable machine with as little
admin time as possible?

Otoh, I do have zero experience using Stable and not sure whether one
can expect to see the fix appear in Jessie in the nearby future?


Sincerely,
Gour

Does your wife use NFS on her netbook?  If not, you can probably just
uninstall rpcbind.

> By looking at package's deps, I'm not sure that installing from testing

Looking at the dependencies, it seems to be possible to install rpcbind
from testing on a stable machine, otherwise you could make a backport
yourself (usually this means just a rebuild in a stable environment).

Either way, you are responsible for maintaining rpcbind on your wife's
machine, since security updates won't be automatically installed
anymore.

> Otoh, I do have zero experience using Stable and not sure whether one

It's rather unlikely that this bug will be fixed in Jessie since the
changes are rather intrusive.

Does she really need to have rpcbind? If not I'd purge it from the
system. Problem solved. :)

Yes, of course, you are right.  I didn't read carefully enough, and we were 
talking about a Debian DVD.  I don't actually know of a Debian derivative 
that has the same policy - except probably Devuan.  But then I don't know

Hello,

I can't understand the problem. Netinstall interrupts due to missing 
rt2800 package? Also in case you are not aware of it there are also 
builds that have already non free firmware drivers. But they are unofficial:

I didn't follow up the whole conversation so i might miss something.

That's good advice...however, it seems it's not enough.

Anyway, the netbook is delivered and let me see if there are complaints
in regard. :-)

There is something else in action, but didn't have time to investigate
before returning netbook to the owner.

Did this some time ago with a Prism54G card and hostap, basically hostap
took care of setting up the PCI Wi-Fi card to act like an access point
and the operating system could then bridge or firewall that interface as
needed: it behaved like any Ethernet interface.

I assume by wireless router you want to build something like the ubiquitous 
plastic home Router+WiFi AP, right?

deloptes is right in that you cannot use just any wifi-card, but there are 
plenty out there that work. Have a look into the linux-wireless wiki [1], 
regard the AP column. Also note that even of the chips that support AP, some do 
so much worse than others - avoid intel as a rule of thumb.

Once you have the hardware, you'd setup a normal router and add hostapd. Regard 
[2] for configuration pointers.

Beware that stock hostapd scans the spectrum for other APs and does not enable 
80211n/ac if it finds anything on the channels it's configured to use. May be 
for regulatory reasons, but all the APs you can buy disregard that, and you can 
patch it out, too.

good luck

Strange thing tho I recently burned an ISO DVD movie

You definitely can.  At least in a roundabout way: the Allwinner H3 SoC
includes an OpenRISC (alongside 4 ARM cores).  Apparently it can clock
up to around 400MHz in there (a good bit less than the 4 Core-A7's
>1GHz).
