Turtl Secure Open Source Evernote Alternative

Turtl Secure Open Source Evernote Alternative


Turtl is a secure, open source Evernote alternative, available for Linux, Windows, Mac, and Android. An iOS version is "coming soon". Firefox and Chrome bookmarking extensions are also available.

Turtl desktop application

The application, which is currently in beta, lets you keep your notes (with Markdown support for the note editor), website bookmarks, passwords, documents, photos, and so on, in a single private place.

Notes can be organized in boards, which support nesting, and can be shared with other Turtl users:

You can also add tags to your notes. The Turtle search allows sorting by creation date, last edited date, or by tags.

Heres the note editor (for a file note):

So what about security? Turtl encrypts the data before storing it, using a cryptographic key, and the password is not stored on the server. Only you and those you choose to share with can read your data. You can read more about the Turtl security and encryption HERE.

The Turtl developers provide a hosted service for synchronizing your notes, which is completely free "until your profile grows past a certain size or you require certain features". At the time Im writing this article, the premium service is not available.

However, you dont have to use the self hosted server - you can run your own Turtl server since its free, open source software, just like the desktop and mobile applications.

Turtl is not as feature rich as Evernote, however, quite a few new features are listed in its roadmap, like import/export to plaintext and Evernote data format, native PDF reader support, interface locking, and more.

I should also mention that the desktop application requires entering the password every time its started, which might be good for security reasons, but can be considered annoying by some.


Download Turtl


Download Turtl application (binaries available for Linux - 32bit and 64bit, Windows 64bit, Mac 64bit, Android, as well as Chrome and Firefox bookmarking add-ons)

To download the source code (desktop, mobile and server), report bugs, etc., see the Turtl @ GitHub.

Arch Linux users can install Turtl via AUR.

To install Turtl in Linux, extract the downloaded archive and run the "install.sh" script. Before installing it, make sure the ~/.local/share/applications folder exists:

mkdir -p ~/.local/share/applications

Important: installing Turtl with sudo makes the application runnable as root only, so either install it without sudo (somewhere in your home folder), or manually fix the permissions (you can take a look at the AUR package for what permissions to set).

For instance, to install Turtl in the ~/turtl folder, use the following command (assumes youve extracted Turtl in your home folder):

~/turtl-*/install.sh ~/turtl
You can use "~/.turtl" instead of "~/turtl" to install Turtl to a hidden folder in your home directory. Or you can hide the ~/turtl folder using a simple trick.

If Turtl doesnt show up in the menu / Unity Dash, restart the session (logout / login).

Ultrathin alternative to silicon for future electronics

Ultrathin alternative to silicon for future electronics


Ultrathin alternative to silicon for future electronics

November 22, 2010
Theres good news in the search for the next generation of semiconductors. Researchers with the U.S. Department of Energys Lawrence Berkeley National Laboratory and the University of California Berkeley, have successfully integrated ultra-thin layers of the semiconductor indium arsenide onto a silicon substrate to create a nanoscale transistor with excellent electronic properties. A member of the III�V family of semiconductors, indium arsenide offers several advantages as an alternative to silicon including superior electron mobility and velocity, which makes it an oustanding candidate for future low-power, high-speed electronic devices.

Ubuntu 14 Install Shinken Alternative to Nagios

Ubuntu 14 Install Shinken Alternative to Nagios


About

"Shinken is an open source monitoring framework based on Nagios Core which has been rewritten in python to enhance flexibility, scalability, and ease of use. Shinken is fully compatible with Nagios and supports its plugins and configurations that can be used on the go without rewriting or adjusting." - Digital Ocean Community

Installation

Download and run the installation script with the following command:

curl -L http://install.shinken-monitoring.org | /bin/bash

Update the administators password:

editor /usr/local/shinken/etc/contacts.cfg

Update the auth secret

editor /usr/local/shinken/etc/shinken-specific.cfg

Install Mongodb support and reboot

cd /usr/local/shinken
./install -a mongodb
sudo apt-get install python-pip -y
pip install pymongo
sudo reboot

Now you can navigate to the server in order to configure it further or view information/alerts. Just go to http://xxx.xxx.xxx.xxx:7767

Add A Server To Monitor

There is no point having a monitoring server that doesnt monitor any other servers. Here we are going to configure the Shinken server to monitor an external entity.

Add a config file to the

/usr/local/shinken/etc/hosts/
path. E.g
editor /usr/local/shinken/etc/hosts/[put-name-here].cfg

Add the following contents to it, ensuring to fill in the details between []


define host{
use linux,ssh
host_name [unique name here]
address xxx.xxx.xxx.xxx
_SNMPCOMMUNITY [Password Here]
}

Restart the service for all changes to take effect.

sudo service shinken restart

Configure the Client

Install the snmpd service before configuring it:

sudo apt-get install snmpd -y
editor /etc/snmp/snmpd.conf

Comment out the following line:

agentAddress udp:127.0.0.1:161

Uncomment this line:

agentAddress udp:161,udp6:[::1]:161

Replace "rocommunity public" with whatever password you put in [Password Here] e.g.

rocommunity [PASSWORD HERE]

I also had to comment out the -V systemonly in order to get CPU/RAM/Disk information etc

Restart the snmpd daemon

service snmpd restart
