Once you’ve started, for the love of God don’t stop.
It takes very little to maintain.
In fact over doing it hurts the maintenance more.
If you stop altogether, the gains are lost shockingly fast.
An injury will kill your will to live.
Take care of your diet. Listen to your body and don’t over do it.
Whether you need to get up to speed in a hurry or just have a passion for acquiring knowledge then this list of links might be of interest.
As an emerging manager I had to soak up info at light speed or I would have drowned in the shallow end.
Learning to navigating people and relationships might be the toughest and most rewarding thing in life.
Here’s a fine list I’ve cobbled of some of the best. There’s already enough in this list to last a lifetime. You’ve been warned!
The Personal MBA
The Cloud: (def’n) The symbol on the diagram indicating the portion of the server and network infrastructure that was far too complex and obfuscated for anyone to spend the time to accurately draw.
Where I keep my iphone selfies; the thing that streams my TV; the place where I accidentally on purpose leaked my sextape.
In all serious it’s a concept that’s changed our understanding our IT and computing forever.
In some ways it’s just a billing exercise to see if we can bill for cheap commodity compute utilization the same as we do other utility billing for power, gas and water consumption.
The technology that’s arisen around this is what gives it real potency. Being able to tie enterprise and consumer applications into just-in-time burstable resources via API using code. Sounds advanced? It is! And it’s advancing by the second.
If you haven’t I encourage everyone to investigate public cloud providers as potential option for spinning up your next server. You’ll learn a ton I guarantee it. Amazon AWS, Google Cloud Engine, Microsoft Azure and many others offer free-trial and heavy discounts for personal and educational use.
The real beauty of cloud is to be able to use code to build infrastructure using configuration tools like puppet and docker. The flat files and containers used to configure the environment can be version controlled, unit tested and stored in repository. This is a vastly different concept than running around with a windows server dvd.
If an application misbehaves the entire environment can be instantly destroyed and rebuilt from runbooks. This shift in mindstep is know as Pets Vs. Cattle
Making the decision to go to cloud isn’t difficult. Preparing your existing workloads for migration is entirely different kettle of fish. While there are many tools available for converting physical workloads into virtual, let’s just say your results may vary. Simple server environments are no problem, but if someone has been spending years perfecting the static monolith, it’s likely going to be a hell of a chore to migrate it, and you’ll almost certainly be rebuilding on the new virtual resources.
Sooner or later you’ll have to get there so might as well have at it hoss!
Helping Clients With Cloud Assessment
I’ll compile a list of every useful link that might help someone get up to speed in a hurry:
I recall thinking as a youngster, “Writing a book must be the toughest job anyone would ever need to accomplish”. Sitting in front of a blank page trying to come up with some way to fill the 3-5 assigned pages on such- and-such topic.
I’ve since become a windbag and keeping ideas succinct so someone might actually READ the book remains the greatest challenge now.
If you’re like me you might have a pile prose sitting around collecting (probably digital) dust. Well if you have a blog or are passionate to the point of being an open faucet then you might consider collating your masterpiece into a table of contents and put the suck up for sale.
As you’d imagine with everything, modern technology has taken much of the pain of getting your words out to the presses.
Here’s great insight from the book by one of my heros, Guy Kawasaki, who always reminds me to bring my humanity to work. Thanks!

Empiricism: SCRUM is founded on empirical process control theory, or empiricism. Asserts that knowledge comes from experience and making decisions based on what is known. SCRUM employs an iterative, incremental approach to optimize predictability and control risk.
Three pillars uphold every implementation of empirical process control: transparency, inspection, and adaptation.
Observers share a common understanding of what is being seen. For example: Those performing the work and those accepting the work product must share a common definition of “Done”.
Inspect SCRUM artifacts and progress toward a Sprint Goal to detect undesirable variances. Should not be so frequent that inspection gets in the way of the work. Most beneficial when diligently performed by skilled inspectors at the point of work.
When a process deviates outside acceptable limits and the resulting product will be unacceptable; the process or the material being processed must be adjusted. Adjustments must be made as soon as possible to minimize further deviation. Four formal events exist in SCRUM for inspection and adaptation:
The SCRUM Team consists of a:
SCRUM Master – Servant Leader
SCRUM Teams are self-organizing and cross-functional.
Responsible for maximizing the value of the product and the work of the Development Team. The sole person responsible for managing the Product Backlog. Product Backlog management includes:
Clearly expressing Product Backlog items
Ordering the items in the Product Backlog
Optimizing the value of the work the Development Team performs
Ensuring that the Product Backlog is visible, transparent, and clear to all Shows what the SCRUM Team will work on next
The Product Owner may do the above work or have the Development Team do it. However, the Product Owner remains accountable. The Product Owner is one person, not a committee. They may represent the desires of a committee in the Product Backlog, but those wanting to change a Product Backlog item’s priority must address the Product Owner. The Product Owner’s decisions are visible in the content and ordering of the Product Backlog. No one is allowed to tell the Development Team to work from a different set of requirements The Development Team
Only members of the Development Team create the Increment. They are Self-organizing – organize and manage their own work. No one (not even the SCRUM Master) tells the Development Team how to turn Product Backlog into Increments. Development Teams are cross-functional, with all of the skills necessary to create a product Increment.
SCRUM recognizes no titles for Development Team members other than Developer regardless of the work being performed by the person. SCRUM recognizes no sub-teams in the Development Team regardless of particular domains that need to be addressed like testing or business analysis. Accountability belongs to the Development Team as a whole. There are no exceptions to this rule.
Optimal Development Team size is:
Fewer than three members decreases interaction and results in smaller productivity; smaller teams may encounter skill constraints causing the team to be unable to deliver an increment.
More than nine members requires too much coordination. Large teams generate too much complexity for an empirical process to manage. The Product Owner and SCRUM Master roles are not included in this count unless they are also executing the work of the Sprint Backlog.
Ensures SCRUM is understood and enacted ,team adheres to SCRUM theory, practices, and rules. The SCRUM Master is a servant-leader for the SCRUM Team. Helps everyone understand which interactions are helpful and which aren’t. They help everyone change these interactions to maximize the value.
Develop the techniques for effective Product Backlog management. They help the SCRUM Team understand the need for clear and concise Product Backlog items. Understanding product planning in an empirical environment and ensuring the Product Owner knows how to arrange the Product Backlog to maximize value, understanding and practicing agility and facilitating SCRUM events as requested or needed.
Coaching the Development Team in self-organization and cross-functionality and helping the Development Team to create high-value products. They removing impediments to the Development Team’s progress by facilitating SCRUM events as requested or needed.
Coaching the Development Team in organizational environments in which SCRUM is not yet fully adopted and understood.
Leading and coaching the organization in its SCRUM adoption. Planning SCRUM implementations within the organization. They helping employees and stakeholders understand and enact SCRUM and empirical product development. Working with other SCRUM Masters to increase the effectiveness of the application of SCRUM in the organization
Minimize the need for meetings not defined in SCRUM.
Time-boxed events such that every event has a maximum duration. Once a Sprint begins, its duration is fixed and cannot be shortened or lengthened. Events end whenever the purpose of the event is achieved. Ensure an appropriate amount of time is spent without allowing waste in the process. Each event in SCRUM is a formal opportunity to inspect and adapt something. Enables critical transparency and inspection.
Failure to include any of these events results in reduced transparency and is a lost opportunity to inspect and adapt.
A time-box of one month or less during which a “Done”, useable, and potentially releasable product Increment is created. A new Sprint starts immediately after the conclusion of the previous Sprint.
Sprints contain and consist of :
During the Sprint:
No changes are made that would endanger the Sprint Goal. Quality goals do not decrease. Scope may be clarified and re-negotiated between the Product Owner and Development Team as more is learned. Each Sprint may be considered a project with no more than a one-month horizon. Each Sprint has a definition of what is to be built, a design and flexible plan that will guide building it. Sprints are limited to one calendar month. When a Sprint’s horizon is too long the definitions may change, complexity may rise and risk may increase.
Sprints enable predictability by ensuring inspection and adaptation of progress toward a Sprint Goal at least every calendar month. Sprints also limit risk to one calendar month of cost.
A Sprint can be cancelled before the Sprint time-box is over. Only the Product Owner has the authority to cancel the Sprint and may do so under influence from the stakeholders, the Development Team, or the SCRUM Master.
A Sprint would be cancelled if the Sprint Goal becomes obsolete or if the company changes direction or if market or technology conditions change. It whould be cancelled if it no longer makes sense given the circumstances.
Due to the short duration of Sprints, cancellation rarely makes sense. When a Sprint is cancelled, any completed and “Done” Product Backlog items are reviewed. If part of the work is releasable, the Product Owner typically accepts it.
All incomplete Product Backlog Items are re-estimated and put back on the Product Backlog. The work done on them depreciates quickly and must be frequently re-estimated. Sprint cancellations consume resources, since everyone has to regroup in another Sprint Planning to start another Sprint. Sprint cancellations are often traumatic to the SCRUM Team, and are very uncommon.
This plan is created by the collaborative work of the entire SCRUM Team. Sprint Planning is time-boxed to a maximum of eight hours for a one-month Sprint. For shorter Sprints, the event is usually shorter. The SCRUM Master ensures that the event takes place. Sprint Planning answers the following:
Topic One: What can be done this Sprint?
The Development Team works to forecast the functionality that will be developed during the Sprint. The Product Owner discusses the objective that the Sprint should achieve and the Product Backlog items that, if completed in the Sprint, would achieve the Sprint Goal. The entire SCRUM Team collaborates on understanding the work of the Sprint.The input to this meeting is the Product Backlog, the latest product Increment, projected capacity of the Development Team during the Sprint, and past performance of the Development Team. The number of items selected from the Product Backlog for the Sprint is solely up to the Development Team. Only the Development Team can assess what it can accomplish over the upcoming Sprint.
After the Development Team forecasts the Product Backlog items it will deliver in the Sprint, the SCRUM Team crafts a Sprint Goal. The Sprint Goal is an objective that will be met within the Sprint. It provides guidance to the Development Team on why it is building the Increment.
Topic Two: How will the chosen work get done?
The Development Team decides how it will build this functionality into a “Done” product Increment. The Product Backlog items selected for this Sprint plus the plan for delivering them is called the Sprint Backlog. The Development Team usually starts by designing the system and the work needed to convert the Product Backlog into a working product Increment. Work may be of varying size, or estimated effort. However, enough work is planned during Sprint Planning for the Development Team to forecast what it believes it can do in the upcoming Sprint. Work planned for the first days of the Sprint by the Development Team is decomposed by the end of this meeting, often to units of one day or less. The Development Team self-organizes to undertake the work in the Sprint Backlog. The Product Owner can help to clarify the selected Product Backlog items and make trade-offs. If too much or too little work, it may renegotiate the selected Product Backlog items with the Product Owner. The Development Team may also invite other people to attend in order to provide technical or domain advice. By the end of the Sprint Planning, the Development Team should be able to explain to the Product Owner and SCRUM Master how it intends to work as a self-organizing team to accomplish the Sprint Goal and create the anticipated Increment.
The objective set for the Sprint. Met through the implementation of Product Backlog. Provides guidance to the Development Team on why it is building the Increment. It’s created during the Sprint Planning meeting. It remains flexible regarding the functionality implemented within the Sprint. The selected Product Backlog items deliver one coherent function, which can be the Sprint Goal. The Sprint Goal can be any other coherence that causes the Development Team to work together rather than on separate initiatives. If the work turns out to be different than the Development Team expected, they collaborate with the Product Owner to negotiate the scope of Sprint Backlog within the Sprint.
15-minute time-boxed event to synchronize activities and create a plan for the next 24 hours. Inspecting the work since the last Daily SCRUM.
Forecasting the work that could be done before the next one. Daily SCRUM is held at the same time and place each day to reduce complexity.
During the meeting:
The Daily SCRUM optimizes the probability that the Development Team will meet the Sprint Goal. The Development Team or team members often meet immediately after the Daily SCRUM for detailed discussions, or to adapt, or replan, the rest of the Sprint’s work.
The SCRUM Master ensures that the Development Team has the meeting and the Development Team is responsible for conducting the Daily SCRUM. The SCRUM Master teaches the Development Team to keep the Daily SCRUM within the 15-minute The SCRUM Master enforces the rule that only Development Team members participate in the Daily SCRUM.
Held at the end of the Sprint to inspect the Increment and adapt the Product Backlog. The SCRUM Team and stakeholders collaborate about what was done. Attendees collaborate on the next things that could be done to optimize value. This is an informal meeting, not a status meeting. The presentation of the Increment is intended to elicit feedback and foster collaboration. Provided a four-hour time-boxed meeting for one-month Sprints.
The SCRUM Master ensures that the event takes place and that attendants understand its purpose.
The Sprint Review includes the following elements:
The Sprint Review provides valuable input to subsequent Sprint Planning. The review of how the marketplace or potential use of the product might have changed or the timeline, budget, potential capabilities, and marketplace for the next anticipated release of the product.
The result of the Sprint Review is a revised Product Backlog. The Product Backlog may also be adjusted overall to meet new opportunities.
An opportunity for the SCRUM Team to inspect itself and create a plan for improvements. It occurs after the Sprint Review and prior to the next Sprint Planning. A three-hour time-boxed meeting for one-month Sprint. The SCRUM Master ensures that the event takes place. The SCRUM Master participates as a peer team member in the meeting.
The purpose of the Sprint Retrospective is to:
Although improvements may be implemented at any time, the Sprint Retrospective provides a formal opportunity to focus on inspection and adaptation.
Designed to maximize transparency of key information so that everybody has the same understanding.
An ordered list of everything that might be needed in the product. The single source of requirements for any changes to be made to the product. The Product Owner is responsible for the Product Backlog including its content, availability, and ordering. A Product Backlog is never complete. The earliest development of it only lays out the initially known and best-understood requirements. The Product Backlog is dynamic; it constantly changes to identify what the product needs to be appropriate, competitive, and useful. As long as a product exists, its Product Backlog also exists. It lists all features, functions, requirements, enhancements, and the Product Backlog items have the attributes of a description, order, estimate and value. As a product is used and gains value, and the marketplace provides feedback, the Product Backlog becomes a larger and more exhaustive list. Multiple SCRUM Teams often work together on the same product. One Product Backlog is used to describe the upcoming work on the product.
Product Backlog refinement is the act of adding detail, estimates, and order. This is an ongoing process in which the Product Owner and the
Development Team collaborate on the details of Product Backlog and usually consumes no more than 10% of the capacity of the Development Team. Product Backlog items can be updated at any time by the Product Owner. Higher ordered Product Backlog items are usually clearer and more detailed than lower ordered ones. More precise estimates are made based on the greater clarity and increased detail, the lower the order, the less detail. Product Backlog items are refined so that any one item can reasonably be “Done” within the Sprint time-box. Product Backlog items that can be “Done” within one Sprint are deemed “Ready”. Product Backlog items usually acquire this degree of transparency through the above described refining activities.
The Development Team is responsible for all estimates. The Product Owner may influence the Development Team by helping it understand and select trade-offs, but the people who will perform the work make the final estimate.
The set of Product Backlog items selected for the Sprint. What functionality will be in the next Increment and the work needed to deliver that functionality into a “Done” Increment. The Sprint Backlog is a plan with enough detail that changes in progress can be understood in the Daily
SCRUM. The Development Team modifies the Sprint Backlog throughout the Sprint. As new work is required, the Development Team adds it to the Sprint Backlog. As work is performed or completed, the estimated remaining work is updated. When elements of the plan are deemed unnecessary, they are removed. The Sprint Backlog is a highly visible, real-time picture of the work that the Development Team plans to accomplish during the Sprint, and it belongs solely to the Development Team.
At any point in time, the total work remaining to reach a goal can be summed. The Product Owner tracks this total work remaining at least every Sprint Review. The Product Owner compares this amount with work remaining at previous Sprint Reviews to assess progress toward completing projected work by the desired time for the goal. This information is made transparent to all stakeholders. The use of burn-downs, burn-ups, or cumulative flows demonstrate the key metrics of the sprint, such as velocity. These do not replace the importance of empiricism. In complex environments, what will happen is unknown. Only what has happened may be used for forward-looking decision-making.
The Increment is the sum of all the Product Backlog items completed during a Sprint. At the end of a Sprint, the new Increment must be “Done,” Which means it must be in useable condition and meet the SCRUM Team’s definition of “Done.” Must be in useable condition regardless of whether the Product Owner decides to release it.
Everyone must understand what “Done” means. Team, members must have a shared understanding of what it means for work to be complete, to ensure transparency. This is the definition of “Done” for the SCRUM Team and is used to assess when work is complete on the product
Increment. If there are multiple SCRUM Teams working on the system or product release, the development teams on all of the SCRUM Teams must mutually define the definition of “Done.” Each Increment is additive to all prior Increments and thoroughly tested, ensuring that all Increments work together.
SCRUM relies on transparency. Decisions to optimize value and control risk are made based on the perceived state of the artifacts. To the extent that transparency is complete, these decisions have a sound basis. To the extent that the artifacts are incompletely transparent, these decisions can be flawed, value may diminish and risk may increase. The SCRUM Master must work with the Product Owner, Development Team, and other involved parties to understand if the artifacts are completely transparent. There are practices for coping with incomplete transparency; the SCRUM Master must help everyone apply the most appropriate practices in the absence of complete transparency. A SCRUM Master can detect incomplete transparency by inspecting the artifacts, sensing patterns, listening closely to what is being said, and detecting differences between expected and real results.The SCRUM Master’s job is to work with the SCRUM Team and the organization to increase the transparency of the artifacts. This work usually involves learning, convincing, and change. Transparency doesn’t occur overnight, but is a path.
Databases – Practical PostgreSQL – The pg_hba.conf file
I recently had a job to do in which I was required to connect to a Postgresql server and run some queries to find some critical data for the team. I wasn’t provided with a logon or any other information about the tables or schema.
Well thank goodness for my old friend google or I wouldn’t have stood a chance against this problem.
What I learned is that without some modifications to a conf file, you will never, ever connect to a database remotely. You may have success connecting from the command line and might be wondering why you can login to the postgres console, but the exact same creds are failing constantly when trying to connect any other way.
Turns out remote connections require the connection mode to be set to ident or trust to either identify or allow the connection based on the user connection manner and credentials used. Without this knowledge you can easily spend a lot of time troubleshooting something that is actually very straight forward.
I didn’t completely understand the issue until I actually setup and installed Postgresql for myself on my vmware homelab.
These two sources were indispensable in my training:
Once I actually set everything up for myself the first it all made a lot more sense. I was able to try all the different scenarios without the fear of breaking production. All in all this was a great learning experience.
These articles are for setting up Postgresql on Centos 7 but there are many other articles out there with similar information for debian or earlier releases.
So get up in them guts and have a poke. I hope you go mildly insane with your new found sql query power.

This is a quick follow-up to the article I posted recently about the Top 100 Most Expensive Search keywords of 2015. In this article I commented on the total lack of willingness most Adwords marketers have for optimization which can result in a lot of waste and very poor ROI. Yes we want the clicks, but we want the right clicks.
I was really impressed by the candor Brad Basteole used in discussing how to do the job well. I think it’s very important to note that although all the topics of the Adwords certification were covered, it’s incredibly valuable to learn this from an outside perspective other than Google.
So if you’re trying to pass an exam, or just want to be better at your Adwords marketing job, I highly recommend you check these videos out.
The modules are pretty short. Usually around 20 minutes and nothing over 30. The presenters are some of the best in the field and are celebrities if you follow certain circles.
I had no idea that all apps built for the Microsoft Store will use these simple languages. I’m not necessarily a big MS fanboy, but you can see why they are so successfully in their strategy. They empower the workforce to use their tools and win market dominance because of it.
I had fun.
