Setting up PostgreSQL v9.1 in Debian GNU/Linux 6.x

After you've installed PostgreSQL and its required dependencies in your Debian server, configure it using the following steps.

1. Check that the user postgres was automatically created for you:
grep postgres /etc/passwd;

2. Start the PostgreSQL service:
/etc/init.d/postgresql start; 

2. Log in as the user postgres:
su - postgres;

3. Log in to the PostgreSQL database using the interactive client application psql:
psql <options> -U postgres;

4. Set a password for the user postgres in the PostgreSQL database:
password;

5. Create a new PostgreSQL database for testing purposes, then disconnect from your PostgreSQL service:
create database <db name> owner=postgres;
exit;

6. Edit the file "/etc/postgresql/9.1/main/postgresql.conf" that enables and disables settings for server connections to your PostgreSQL service.

7. Edit the file "/etc/postgresql/9.1/main/pg_hba.conf" that enables and disables settings for incoming network connections to your PostgreSQL service.

8. Restart your PostgreSQL service:
/etc/init.d/postgresql restart;

9. Automatically start your PostgreSQL service on boot up:
update-rc.d  postgresql <options>;

10. Edit the file "/etc/hosts.allow" that's the hosts access control list for allowing access to services on your server from specific hostnames, IP addresses, networks, and FQDNs:
<service or wildcard>: <hostname> <ip address>/<subnet mask> <fqdn>

11. Edit the file "/etc/hosts.deny" that's the hosts access control list for denying access to services on your server from specific hostnames, IP addresses, networks, and FQDNs:
<service or wildcard>: <hostname> <ip address>/<subnet mask> <fqdn>

12.  Allow incoming and outgoing client connections to your PostgreSQL service through your firewall:
iptables -A INPUT -i <interface> -p tcp --dport 5432 -j ACCEPT
iptables -A OUTPUT -o <interface> -p tcp --sport 5432 -j ACCEPT

OpenStack+Ceph as Software-Defined Storage

SDS reduces the costs of the management of growing data stores by decoupling storage management from its hardware to allow for centralized management of cheaper, popular commodity hardware. The example SDS ecosystem uses open source software like OpenStack as a front-end interface on top of Ceph as the resource provider of a RADOS cluster of commodity solid-state drives. OpenStack provides user-friendly wrappers for accessing and modifying underlying Ceph storage. OpenStack comes in the form of distributed microservices with RESTful API's: Block (Cinder), File (Manila), Image (Glance), and Object (Swift). Each microservice can scale-out as a cluster of stand-alone services to accommodate the varying demands of high-growth storage. With OpenStack the underlying Ceph storage can address the block storage needs, file storage needs, image storage needs, and object storage needs of datacenters adopting open source as their new norm in an industry trend for high performace and high a...

The meaning of time in reinforcement learning

Reinforcement learning (RL) is one of three basic machine learning paradigms, alongside supervised learning and unsupervised learning. Reinforcement learning is concerned with how software agents ought to take actions in an environment in order to maximize the notion of cumulative reward through the process of trial and error. In reinforcement learning an agent starts at an empty state then analyzes the available datasets according to a policy of positive states and negative states. Rather than being explicitly taught as in supervised learning the correct set of actions for performing a task, reinforcement learning uses rewards as signals for positive states and punishments as signals for negative states. The agent obtains the best path to a desirable reward as a cumulation of positive states and negative states. As compared to unsupervised learning, reinforcement learning is different in terms of goals. While the goal in unsupervised learning is to find similarities and differences...

Principal Component Analysis

Principal Component Analysis (PCA) is a common technique in statistical analysis, widely used for pattern recognition, data compression, image preprocessing, signal-noise analysis, and high resolution spectrum analysis. Principal Component Analysis transforms a group of activites into a set of unique components, where each component has a numerical degree of distance and relatedness from an agreed on centered component. The first component has the largest possible variance (it accounts for most of the variability in the group). Each succeeding component has the highest variance that is orthogonal to the preceding components. The transformation of the group proceeds linearly from a group with a high degree of dimensionality to a group with a low degree of dimensionality of which the components of the group with a low degree of dimensionality are uncorrelated. Principal Component Analysis is also used in the forecast of a most likely outcome through time-series analysis and regress...
