Time to drop tuncl

I just realized that 'tunctl' is not required anymore.

Now you can create tun/tap devices with 'ip':

    ip tuntap add eth0 user USER11 group GROUP11 mode tap

Proper way to print errno value.

I use this combination of bash and python to print meaning of errno value:

strerror () { python -c "import os; print os.strerror($1)"; }

There is also 'perror' program, but it is distributed with mysql only.

sysctl with autocompletion is really great.

> sysctl -n net.
Display all 758 possibilities? (y or n)
> sysctl -n net.ipv
Display all 711 possibilities? (y or n)
> sysctl -n net.ipv4.ip_
net.ipv4.ip_default_ttl           net.ipv4.ip_forward               net.ipv4.ip_local_reserved_ports
net.ipv4.ip_dynaddr               net.ipv4.ip_forward_use_pmtu      net.ipv4.ip_nonlocal_bind        
net.ipv4.ip_early_demux           net.ipv4.ip_local_port_range      net.ipv4.ip_no_pmtu_disc        
> sysctl -n net.ipv4.ip_forward
net.ipv4.ip_forward           net.ipv4.ip_forward_use_pmtu
> sysctl -n net.ipv4.ip_forward
0
> sysctl -w net.ipv4.ip_forward=1
net.ipv4.ip_forward = 1

Emacs column marker

Very often some code style has limited length of code line and its quite good, when IDE knows about such limits.

I've added to Emacs column-marker

(add-to-list 'load-path (expand-file-name "~/emacs/column-marker"))
(require 'column-marker)
(add-hook 'ada-mode-hook (lambda () (interactive) (column-marker-3 79))) 

Now, if in Ada code some line exceeds 79-symbols limit, Emacs will highlight it with red.

Error: Value too large for defined data type

During compilation of program sources in Ubuntu Linux in folder, which was mounted via CIFS from windows I've got the following error from gcc:

Error: Value too large for defined data type

At the first thought it is an error in gcc, but actually the problem was in mounting directory via CIFS .

To fix this error the following options should be added to fstab or mount command line:

nounix,noserverino 

I've got this info from here.
