Summary: The Five Dysfunctions of a Team

The Five Dysfunctions of a Team, by Patrick Lencioni, published by Wiley, John & Sons, Incorporated.




The first step towards reducing misunderstandings and confusion within a team is to understand that there are five dysfunctions, and that each one that applies has to be addressed separately.   

1. Absence of Trust

The root cause of absence of trust lies with team members being unable to show their weaknesses; to be vulnerable and open with one another. The absence of trust is a huge waste of time and energy as team members invest their time and energy in defensive behaviors, and are reluctant to ask for help from – or assist – each other. Teams can overcome this dysfunction by sharing experiences, following through in multiple ways, demonstrating credibility, and developing strong insight into the unique characteristics of team members.

After that, exit and update as prompted. Either then through the command line or graphically from the software updater, update.

Troubleshooting in Redshift


by Narendra Dubey

Redshift is a one of the most popular data warehousing solution, thousands of companies running millions of ETL jobs everyday. The problem with MPP systems is troubleshooting why the jobs are hung, which are the queries blocking others.

To troubleshoot problems like this could be a real nightmare if you are new to Redshift, in this article I have tried to aggregate the tables and queries you should always keep handy if you work with Redshift on daily basis of planning to start using

Table Overview

First of all lets familiarize our self with some of the tables needed to troubleshoot a problem.

Ubuntu 18.04 LTS ‘Bionic Beaver’ - 11 Things To Do After Installing

Enable Media Codecs


Ubuntu offers to install third-party codecs, restricted extras (like the Adobe Flash plugin) and proprietary drivers automatically as part of the install process.

But if you if you didn’t notice the tick box during install (or forgot about it entirely) you won’t be able to play MP3 files, watch online videos, or take advantage of improved graphics card support until you install all of the relevant packages.

Install a Better Ubuntu Theme

And the easiest way to give Ubuntu a new feel is to install the Communitheme from Ubuntu Software.

Blood on the Clock Tower Sects and Violets

From Blood on the Clocktower Wiki


Sects & Violets is the craziest of the three editions included in the base set. Good characters get amazing information each and every night. However, the evil team is extremely varied and threatening and can throw massive confusion into the mix. Characters change alignment. Players change characters. Even the evil team can lose track of who is who. This is also the first appearance of madness, which throws all manner of spanners into the works.

Intermediate. Recommended for players who want to do wild and unexpected things, pushing the limits of what can be achieved in a bluffing game.

Larger font: character sheets, character tokens

I used the 1.5 inch for the main tokens, but I had to reduce the print out to about 85%.

I used the one inch for the grmoire tokens.

pfsense basic configuration


Install pfsense with at least two network connections. Pfsense will assign one to be the WAN interface, the network for the WAN interface should not be 192.168.1.x as this needs to be reserved as the default LAN for the web configuration (do not try to connect to the web configuration on the WAN interface). Pfsense will assign the other to be the LAN interface.  Attach a computer to this interface to use a browser to configure.

pfSense Add Static Route

There is a server on the DMZ that we want to access.

System -> Routing.

There are three tabs (“Gateways“, “Routes“, “Groups“);

click on the “Routes” tab and click the “plus” button to add a new route.

At “Destination“, type in the IP address of the destination network, which in our case is the DMZ network (assume it is
