Configure EMACS/Geiser

look at the file ~/.configure/guix/current/bin which will provide you with the guix/guile binary path and the recipe for %load-path.

In EMACS configure Geiser with the above executable, and for the load path entry (which requests a file) use the ~/.configure/guix/current/bin file.

Mostly for Debian, some Arch

Packages

To see all the files the package installed onto your system, do this:
dpkg-query -L

To see the files a .deb file will install
dpkg-query -c <package_name.deb>

To see the files contained in a package NOT installed, do this once (if you haven’t installed apt-file already:
sudo apt-get install apt-file
sudo apt-file update

then
apt-file list ‘package_name’

to find a file:

$ find / -name 'program.c' 2>/dev/null

$ tar zxf file.tar.gz
$ tar zxf file.tgz

$ tar xf file.tar.xz

;;Now change directory
$ ls
$ cd path-to-software/
# ./configure
# make
# make install

dpkg-source -x foo_version-revision.dsc

will extract the package into a directory called foo-version.

If you want just to compile the package, you may cd into foo-version directory and issue the command

 dpkg-buildpackage -rfakeroot -b

to build the package (note that this also requires the fakeroot package), and then

 dpkg -i ../foo_version-revision_arch.deb

to install the newly-built package(s).

Introduction

In the past I have used Ubuntu One until it went out of business, then ownCloud, until it went out of business. I have been looking for a method to perform bidirectional backup to a directory on my Hostgator shared server. Osync initially looked promising, but SSHs into the server too many times, exceeding the 12 allowable attempts per IP per 90 seconds imposed by Hostgator. I fell back to rsync, and had to hack the “bidirectional” feature in an unsatisfactory way.

Rsync

See here for setting up SSH keys. The command to upload from a local directory ~/syncd/ to Hostgator, preserving directory structure:

cd ~/syncd/
rsync -avzP --delete --rsh='ssh -p2222' /home/mbc/syncd mbcladwell@123.123.123.123:/home2/mbcladwell/public_html/

;;for test
rsync -avzP --delete --rsh='ssh -p2222' mbcladwell@123.123.123.123:/home2/mbcladwell/public_html/lnsDFoKytr /home/mbc/ 

for cron edit the file using the command crontab:

Xfce4

A debian image contains Xfce4 as the default, so installation is easy. Good selection of software without all the crapware that comes with Gnome. If you prefer Arch, Manjaro Arch using Xfce4 as the default window manager. More comprehnsive utilities than stripped down WMs like I3.

When installing Debian, there is a special image for automatically installing Xfce4 (instead of Gnome).
downloaded torrent from http://cdimage.debian.org/debian-cd/7.4.0/i386/bt-cd/
use sha256sum debian-7.4.0-i386-xfce-CD-1.iso to verify

debian-7.4.0-i386-xfce-CD-1.iso.torrent 660 MB

Do not use unetbootin. Instead:

1

# fdisk -l   ;;to identify USB drive
# cp debian.iso /dev/sdb1
# sync

elect special installation to be able to install with Xfce
Selecting encrypted hard drive will start a >10 hour random write to disk which you can cancel out of and continue the install.

Select “Guided – use entire disk and set up LVM”; this is for the xfce window manager installation
Partition all files in one partition.
Once installed, modify the sources and UPGRADE to the latest packages.

#nano /etc/apt/sources.list

comment out the line referring to a cd and add:

deb http://http.debian.net/debian/ wheezy main contrib non-free
deb http://ftp.us.debian.org/debian/ sid main #for electrum

#apt-get update && apt-get dist-upgrade

From the documentation:

upgrade: used to install the newest versions of all packages currently installed on the system.
dist-upgrade: in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages.

Add to startup

Go into settings > settings manager > session and startup > application autostart > add
name: MyStartItem
command: bash /home//mystartupscript.sh

Another option is to modify /etc/lightdm/lightdm.conf to add the following options:

display-setup-script > calls your mycustomloginvideo.sh before the login screen appears
session-setup-script > calls your mycustomdesktopvideo.sh before the user desktop session starts

[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu
;;for your login screen, e.g. LightDM (Ubuntu 11.10) or GDM (11.04 or earlier)
display-setup-script=/usr/share/mycustomloginvideo.sh
;;for your desktop session
session-setup-script=/usr/share/mycustomdesktopvideo.sh
