Articles, notes and random thoughts on Software Development and Technology
I’m transferring some apps downloaded for my Atari ST (don’t ask) to floppies that are formatted with 80 tracks and 8 or 9 sectors, on double density disks (formatted on the ST). From what I understand these are MS-DOS readable but not exactly FAT format. Anyway, they don’t seem to mount by default on Ubuntu as it doesn’t know what format they are, but forcing a mount with this seems to work:
sudo udisks --mount /dev/fd0
seems to do the job (tip from here)
Need to mount an old Iomega ZIP drive with a Parallel cable on Ubuntu? Here’s how – I only needed to add the ppa driver to /etc/modules and I was all set:
Quick note to remember this syntax as every few months I find a need to do a grep within a number of files:
find -name "pattern" -exec grep "pattern" {} ;
Grep options:
-H print filename in results
-n print line number where match was found
-l limit match to first found match in file (useful if you want to find files containing a match but don’t care how many matches are in each file)
Pipe to wc -l to count file occurrences, eg:
find -name "pattern" -exec grep -l "pattern" {} ; | wc -l
Use egrep if you need to use regex in the pattern.
There’s probably many ways you could configure a similar setup to this, but here’s what worked for me.
This is for static IP on wired, and a different static IP on wireless, where the wireless is using WPA2. I also have two different routers one for wired and for one wireless. Replace static_ip_here with your required ip addresses, and x and y with the IP addresses for your routers.
Edit /etc/network/interfaces:
