Mount Nexus5 to Ubuntu 12.04

Instruction how to connect Nexus phone to Ubuntu 12.04:

1) Activate developer options on Nexus 5, instructions, that mode have to be switched ON always to be mounted.

2) just follow http://bernaerts.dyndns.org/linux/74-ubuntu/268-ubuntu-automount-any-mtp-device , at the end of article there is a script that do all that steps automatically (that require only 2 chapter to be done).

ATTENTION: unlock phone before connection to PC, if phone is locked auto connection/mount is not happen!!!!

it works for any device - Nexus 4, Nexus 5, Nexus 7, .... that use MTP protocol.

Only one minor nuance is noticed: Nautilus does not copy files/folders if you use Tabs in Nautilus, workaround just use separate nautilus windows.

move window to other monitor at ubuntu

You need to install Compiz Config Settings Manager:
"sudo aptitude install compizconfig-settings-manage"

and launch it from Dash(main button) by filtering "compiz".

select in the "Window Management" section a "Put" item. With that enabled, you can set a shortcut key in the "bindings" tab for "Put to Next Output". By default, it's disabled, but is easy to set.
No restart is required (at least on Ubuntu 12.04 x64).

If you have two monitors - this combination will work like swap of window location on monitors.

My default is "Cntl+~".

Share folder between Windows and Ubuntu 12.04 by mean of Samba

The best way to share folder between different Windows and Linux is to share it on Linux and let Windows explore it in network. Sharing on Windows and exploring from computer and folder from Ubuntu is never stable (Linux guru could do this, but it is not for ordinary user).

Follow pretty good illustrated instructions, works fine for 12.04:
http://www.liberiangeek.net/2010/06/how-to-quickly-change-workgroup-name-in-ubuntu-10-04-lucid-lynx/

Restart samba service after each sharing( just in case :) ), in Ubuntu 12.04 as:

sudo restart smbd

If smth does not work, restart Linux PC, this will help windows to see your Linux :). 

RDP connection from Windows to Ubuntu 12.04

manual: http://www.ubuntututorials.com/remote-desktop-ubuntu-12-04-windows-7/

That connection create only new connections to PC, no way to connect to existing session.

unfortunately did not worked for me as screen after login is empty.
Here is advise how to fix that problem, see two last comments of "arrghushakaboorga".

It works, but ! if you try to launch FireFox or Chrom from that session, Firefox will fail to launch if it existing in different session, Chrome launched in new session and disappeared (it appear in my real session at laptop).

So that behavior is not appropriate, failed to fix, fed up ... .

How to show git branch/status information in bash

extension for terminal/command line to use git more effectively:

For Mac users, (zsh): https://github.com/olivierverdier/zsh-git-prompt

For bash(works fine for Ubuntu): https://github.com/magicmonty/bash-git-prompt
I do following update for /home/USER/.bash/gitprompt.sh :

PROMPT_START="$WHITE$Time12a $Yellow$PathShort$ResetColor"
PROMPT_END=" $ "

For simple branch show(works very fast), (link second comment):
Simply add following line it ~/.bashrc
PS1='[\u@\h`__git_ps1` \W]\$ '

Install Sublime text to Ubuntu

Sublime text - text editor that Mac user love to use, so let try it in Ubuntu,
What I like:
- it is quick
- outline view of whole file on the right side.
- Columns/Block selection, how to.
- line numbers as out of the box functionality.

Instruction:

sudo add-apt-repository ppa:webupd8team/sublime-text-2
sudo apt-get update
sudo apt-get install sublime-text

Print a folders structure to file

I come to a tast to examine whole source code structure on SVN and propose restructure it to new layout. some projects were grouped in sub folders.

Install "tree" tool:
sudo apt-get install tree

Command to print tree, without temporary and useless folders, dig in 4th level:
tree -L 4 -d -I "target|webapp|doc|docs|site|src|deploy|sh|java|data|scripts|lib|conf|work|bin|web|webscr|META-INF|hibern|www|css|images|templates|test-conf" > structure.txt

Output is like:

├── auth
│   ├── apache-modules
│   │   ├── auth_client
│   │   │   └── test
│   │   ├── googleauth
│   │   │   └── example
│   │   ├── jansson-2.2
│   │   │   └── test
│   │   ├── m4
│   │   └── mod_some_auth
│   ├── auth-client
│   ├── auth-errors
│   ├── auth-server

Ubuntu get popularity from other Linuxes

Ubuntu become more and more popular, but is it due to new users that come from Windows ?

I do believe to wikipedia statistics as it only resource that is visited by all internet user no matter what OS or browser they use.

data sources links:
http://stats.wikimedia.org/wikimedia/squids/SquidReportOperatingSystems.htm
http://stats.wikimedia.org/archive/squid_reports/2011-10/SquidReportOperatingSystems.htm

Result show that Ubuntu get popularity from other Linux systems, but we see 0.07% of grow :) in general.
Does it mean that Linux users become more lazy and choose Linux that works out-of-the-box, and fed-up with doing all from scratch ? or it is just statistical rounding that significant grow other OS in amount of users
red - decrease of popularity.
green - grow of popularity.

Browser HL-4570CDW for Ubuntu 12.04

Drivers are not in ubuntu set of driver, need to be installed manually:
http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html#HL-4570CDW%20/%20HL-4570CDWT

installed both packages by means of Ubuntu Center. Center show WARNING of package structure but still allow you to install. I continued installation - works fine.

After drivers are installed, driver could be seen(automatically picked up) from install printed wizard. Install driver before launching "Printing" application.

Issues:
After "Print Test Page" is done - need to go to printer and press button "GO" on printer.
Printing from other application does not need this.

Eclipse complains about com.sun.tools 1.5.0 is missing

During compilation of some opensource project you could come up to error "artifact  com.sun.tools 1.5.0 is missing" in Eclipse, but compilation works fine from terminal.

Problem is in what JDK Eclipse use and provide it the same path.
check correctness of $JAVA_HOME
You need to check $PATH variable to be sure that required JDK is in Path.
Even you have JAVA_HOME/bin in path, java could be taken from other location due to the fact that it could be found in path early than your, to check it:

which java
ls -la /usr/bin/java
ls -la /etc/alternatives/java

Make sure that /etc/alternatives/java points to your JDK. In my case it was to OpenJDK but my JAVA_HOME was pointed JDK 1.6. So I removed all openjdk packages from Synaptic in Ubuntu and  after that all worked fine.

Similar problem is described here.
