Architectural Integrity Meets Primal Wellness: Engineering a Sauna for Optimal Health and Durability

As professionals in the building environment, we know that true quality emerges when design decisions are made with both aesthetic beauty and structural resilience in mind. I recently completed a project that perfectly illustrates this principle: a deeply integrated sauna structure designed to withstand extreme conditions while offering profound health benefits.

The Challenge of Placement and Access

Building on a difficult site demands meticulous planning and execution. The location of this sauna required significant manual site preparation. Due to the rugged terrain, moving all necessary building materials was a challenging logistical feat, emphasizing the premium placed on every element chosen for the final structure.

Constructing the Perfect Envelope: Defying the Dew Point

When designing a space defined by intense, fluctuating humidity - like a sauna - the issue of the dew point becomes paramount. Condensation forming within the wall cavities leads directly to rot and mold, compromising both the building's longevity and occupant health.

Our crucial design decision to combat this involved constructing robust, layered wall assemblies that deliberately encourage airflow between the building layers. This controlled ventilation system ensures a perpetually dry building by carrying away moisture vapor before it can condense within the envelope. This preventative measure is fundamental to promoting a durable and structurally sound building for decades. Visible elements of the construction include vertical stud framing and insulation materials integrated into the wall structure.

Performance Through Precision Materials

We selected materials not just for their looks, but for their commitment to performance:

Custom-Milled Rhombus Siding: The exterior features unique custom-milled rhombus siding. This deliberate profile enhances the building's aesthetic appeal while serving as an effective rain screen, supporting the ventilation strategy and rapid drainage.

Triple-Glazed Windows: Windows are often the weakest thermal link. To mitigate heat loss and maintain a high level of energy efficiency, we specified high-performance, triple-glazed windows. This choice minimizes thermal bridging and ensures internal glass surfaces remain warm, further preventing condensation risks inside the heated space.

The custom milled rhombus siding was not only aesthetic, it was also the least expensive.

The Heart of the Ritual: Heat, Cold, and Restoration

The interior is designed around the powerful, transformative experience of the heat and the stones. A moderately sized stove capable of holding a substantial volume of volcanic stones dominates the space, crucial for generating rich, intense löyly (steam). Heating the space is a manual process, requiring tending to the firebox to achieve the desired temperature. Three large spoonfuls of essential oil infused water poured over the hot stones brings the temperature up in 3 - 5 degree bursts.

Adding essential oils to the water before pouring over the hot stones provides additional wellbeing.

The sauna and the associated features are intended to work together as a holistic wellness facility. The structure is integrated with a separate, adjacent cold feature, built by converting the properties legacy surface well. The below-grade concrete structure and ladder is designed for a splash or cold plunge - that is situated a few steps from the sauna building. A deep breath and quickly lowering yourself into the 6'6" pool allows you to emerge into a different dimension.

The Thermal Cycle for Deep Wellness:

The full restorative experience involves cycling between the heat and the cold. Based on traditional practices, the cycle emphasizes a deep heating step followed immediately by a rapid cooling phase.

A suggested cycle involves:

1. Heating: Spending time in the intense heat of the sauna.

2. Cooling: Transitioning directly to the cold plunge or splash pool for up to three minutes.

3. Rest: Resting outside for another 5 to 10 minutes before returning to the sauna.

This cycle is typically repeated three times to maximize circulatory benefits and promote relaxation. Taking the opportunity the sit and relax in the cool air, or by an outdoor fire, and breathe deeply further enhances the experience.

It should be noted that while the existence of the heated sauna and the cold plunge structure is supported by the sources, the specific timing, duration (3 minutes in the pool, 5-10 minutes outside), and repetition count (3 times) for this wellness protocol are details that need to be considered by the user. Know your body and how it responds to heat and cold cycles. Good to consult with your physician before using a sauna and cold pool.

Sunset and views from the sauna are outstanding. And the deck provides enough space for laying about and completing a few yoga postures.

The colour of the wood burning firebox always adds to the ambience and provides enough light to choose a few more pieces of wood organized under the interior bench seats.

The dry summer months also provide an opportunity to maintain the lands around the sauna and splash pool.

This project demonstrates that successful architecture transcends mere shelter; it is about engineering environments that actively support health, durability, and a profound connection to beneficial natural rituals.

Blogging in a time of AI

I am renewing my frequency in blog posting. This will come after an almost 5 year break from blogging. I am returning because I am back to working on open-source software, educational projects, and the digitization of oceans. And I know I have a learning and success journey to share. 

Some Background

I started blogging twenty years back. Yes, 20 years. I was an early adopter and I was involved with technology startups and how the internet was influencing education. At this time I was a big believer that blogging was about content creation. Adding to the collective of the internet by adding meaningful and descriptive content rather than only being a consumer of content. To date, I have published over 500 posts to my assorted blogs. Most of this work was in the first 10 years of my blogging. I essentially posted once a month for the first 10 years. I did have a year where I posted over 100 times. As a summary this is how I posted over the last 20 years.

2004 to 2014 - I published 420 blog posts with good readership. I had a year where I posted more than 100 times. I set this as a goal / experiment to see if I could post twice a week. I did this while holding full-time work, which meant many early mornings and late evenings writing. I learned a whole bunch and my writing skills improved. 

The themes for these first ten years was mostly; 

• technology leadership for startups, 
• hard-core technology and approaches, 
• innovative and emerging education, 
• and the intersection of these three.

2015 to 2024 - I published only 41 blog posts during this 10 years, and nothing in the past three years. Honestly, I was distracted by raising my family of three and doing a whole bunch of life living. Not so focused on work and career advancement. 

The themes for the last ten years have mostly been; 

• integrating with technology community in St. John's NL (I moved), 
• continue my work on digital badges and micro-credentials,
• development of an ocean data startup (still a work in progress),
• and working the idea of a reference architecture for the digitization of oceans.

Most exciting of all this is more than 1/2 million views during the 20 years and at some points having over 2500 weekly views. What have I learned from all this blogging? Mostly, that having to write and publish openly to the internet helps the overall community knowledge and it helps me learn more deeply in these chosen subjects.

Next Steps

Again, I will use blogging as my cognitive gymnasium. My subjects themes haven't changed and I will focus upon two main subject areas and continue with updates to this critical technology blog;

1. Education technology, Heutagogy, and the self-directed learner.
• The Happy Heutagogue - https://heutagogue.blogspot.com/
2. Many things related to, and in support of, the authoring a reference architecture for the digitization of oceans.
• The Ocean Set CTO - https://oceanset.blogspot.com/
3. And my continued musings about technology through my gen X view of the world.
• Critical Technology - https://criticaltechnology.blogspot.com/

With all my work and R&D efforts I will learn a bunch of stuff and apply this to the real world through the successful projects I am a part of. I will reflect upon these successes and all that I have learned I will create content that can provide further learning for those around me. And hopefully they will also be entertaining reads.

Collaborating with your AI partner

Blogging has changed for me. There has been a lot of technical and social change since I did most of my blog posting over a decade ago. I had a few focused subjects I was very passionate about, and I wrote about them often. I wrote unincumbered for I would consider myself an early adopter and there was less people publishing to the internet in my chosen subjects. Today there is much more content covering these subjects. And all this content comes in photos, videos, audio, and written articles. Artificial Intelligence is doing a great job of creating and summarizing the content which addresses the complex audience needs and their questions and prompts. Content creation has changed. For a human content creator I believe our work needs to be more intelligent, critical, and creative. Content creators in a time of AI need to do what the AI cannot; daydream, reflect on unrelated subjects, see unlikely connections, be critical, add meaning, create new content that falls between the generated content, fact check and confirm, and add more human intelligence.

How will my blog writing process change? Um, it already has...

I must reflect and draw upon my mastery and do my best to add the new content that AI cannot... AI needs our creativity because it has already parsed the published body of human knowledge. For more insight on my approach, use your favorite large language model chatbot (ChatGPT, Gemini) with the prompt 'limitations of generative AI' followed by the prompt 'How would you suggest a human writer overcome these AI limitations'.

Step by Step my blogging will partner with AI and follow this basic approach;

1. Capture ideas for new posts, be verbose, be imaginative, think about context
2. Put these ideas to incomplete blog posts, work ideas for days, for weeks...
3. Read extensively, add to the understanding of any specific idea
4. Keep references, cut and paste to the bottom of the related incomplete posts
5. Prompt AI with phrases from the idea generation
6. Take blocks of text from written ideas and push them into generative AI, be critical, harvest what you can.
7. Take the written blog post and ask AI for a rewrite. Change your audience. be critical, harvest what you can.
8. Try and see, try and write, what AI cannot... add to the body of human knowledge.
9. Add story telling to improve the overall post
10. Find pictures to support the writing, format for engagement. Use AI to generate images from passages of text taken from the blog post.
11. Format, edit, improve, repeat. Be bold... Publish.
12. Use AI to improve the quality of the writing... Publish again.
13. Rest, reflect, improve... Publish again.
14. Yes, I am an advocate to publish before writing is perfect. Publish and then make improvements over the days and weeks that follow. Once the post is considered finished finished... promote it on social media.
15. Identify what is most important about the post and rewrite for the LinkedIn business audience. Publish to LinkedIn.
16. Repeat...

It's Alive! The Elastic Stack as our Data Lab

So much technical work, so little time! I finished my first three sprints toward standing up the data lab. Standing up infrastructure from scratch so you have clean new compute power is fun, and also a lot of work. Particularly when you include; doing it right, taking no short cuts, and making sure it is secure.

Sprint 0: Setup Ubuntu 20.04 Server with ELK stack.

This was mostly rehydrating virtual server infrastructure I hadn't used in 8.5 years. It needed an upgrade from all perspectives and had a completely new OS. I implemented the ELK stack and made a couple of security changes to lock it all down. I ran a few tests by setting up a couple of websites, getting the JSON confirmation from ElasticSearch, and called up the Kibana dashboard. Oooo... sweet success!

Sprint 1: Vulnerability Assessment. Security changes if required.

This evening I spent some time poking at the overall vulnerability of the server and with the ElasticSearch and Kibana services. I made a few additions and changes for further locking down the services and believe they are as secure as they can be for this first release. Very happy to feel reasonably confident about it's being locked down. Maybe, I'll get lucky and get some free PEN testing. ha.

Sprint 2: Identify and register some well aligned domain names.

I registered the following domain names, even considered buying one... it would have been too expensive. I'll implement the data lab on the oceansofdatalab.com site when it becomes closer to being a minimal viable product (MVP).

• oceansofdatalab.com
• oceansofdatalab.org
• oceansofdatalab.net
• oceansofdata.net
• sevenseasofdata.com
• sevenseasofdata.org

For Contract Database Administrator

Do you require contracted database administration? Medium to small organizations using database technology to store corporate data definitely need database administration to care and feed for there database technologies. This care and feeding includes, and is not limited to;

• 
  Install and maintain database servers.
• Optimize database security.
• Build and maintain ETL pipelines.
• Performance tuning of databases.
• Storage optimization for databases.
• Implement DataOps for up-to-date business analytics and its need for continuous data.
• Install, upgrade, and manage database applications.
• Create automation, and schedule, repeating database tasks.
• Ensure recoverability of database systems.

If you require any, or all, of these database administration task we can help. With over 30 years of database experience complimented with a technology degree in database management we can work remotely to keep your databases healthy and reduce business risk. Part-time or full-time, reasonable rates.

Peter, we need to integrate data more easily.

I liked this article on Fundamental truths when it comes to innovators. I do think Elon Musk and Jeff Bezos have figured out how to be crazy successful in business. I do wish they were more philanthropic with the monies they have accumulated from their success. I digress...

I like the idea of a fundamental truth as a foundation for your business that doesn't change through time. And when I think about my commitment to build a data services business, I have now started to think about what would be the fundamental truths?

1. We need to access and integrate data more easily.
2. We need better ways to visualize, communicate, and understand, the data.
3. We would like to reduce the compute and storage costs of data.

These are what I came up with through my review of my initial thinking of fundamental truths. I know there will be a few more and these three will be edited as my idea grows and gets greater footing.

Building the Data Lab Technology Stack

The idea of building a data lab is emerging from my ocean data conversations and how to best utilize my knowledge and skillset within this opportunity. In my mind, the service offering would be twofold;

1.  Data Engineering / Software Development consulting and services with focus on ocean data. We will do the heavy lifting of extracting, cleansing, transforming, and loading your data. And then we will help with analysis and visualizing the data. We are comfortable working in both the open source and Microsoft technology stacks.
2. Standing up (and data loading) the technology stack for the data lab. You are going to need to host all this compute power and storage somewhere. It could be on-premise. Most likely, it will be in the cloud. We can help with this also. We could build it in Azure, using the Microsoft technology stack. Or we could build it using an Open Source stack on top of Linux in any of the hosted environments of Azure, AWS, or Rackspace.

https://stock.adobe.com/

How do you build a low priced, large compute, technology stack to support data engineering efforts, implement a data lab, and showcase these new services capabilities. The low price is the key factor given the current startup state of this ocean data endeavour. Particularly, when you think of the cost of compute for processing and storing large amounts of data. I believe the the best way forward is as follows;

1. Use open source where you can. Fortunately, many of the infrastructures, tools, frameworks, and programming languages for the data lab are open source.
2. Automate the build so it can be built and torn down with ease. This would eliminate the need for the stack to always be running.
3. Store the data at it's source, if possible. Fetch, and load, the data when you automatically rebuild the stack. Keep in mind this limits the amount of big data you can store locally, and loading large amounts of data can cumulatively take days. Be mindful of this. 

Note: this stack is to showcase the services capabilities. A full data lab would also need the ability to both persist and fetch data. It's going to take some time to build the data lab!

The Data Lab Technology Stack

The deployment of this technology stack will use open source wherever possible running on a Linux (Ubuntu) Server hosted at Rackspace. The rational for these decisions are;

• Little to No licensing costs 
• Strong familiarity with Rackspace as hosting company
• Existing domain name (endeavours.com) hosted with Rackspace
• Extensive experience with Ubuntu Linux in a hosted environment
• Familiarity with deploying data intensive solutions using the ELK stack
• Experience programming in Python

Note: The deployment of this technology stack will happen in phases, where each phase will complete with some basic tests to ensure the stack behaves as desired.

Phase 0

Phase 0 will be a basic ELK stack running on an Ubuntu Linux server hosted at Rackspace with access via the endeavours.com web domain. The use case for where the data comes from, how we transform it, the analysis, and visualization is still to be determined. This use case will be used for testing this first iteration of the newly stood up data lab. Exciting times!

Phase 1

During phase 1 we will add the Python programming language to the technology stack and use it for two purposes;

• Apply a model to the data using Python.
• Present the processed data to a web page for display.

Phase 2

During phase 2 we will add Kafka as an infrastructure resource, identify some additional data sources, and pre-process the data before it gets loaded into ElasticSearch.

Phase 3 and beyond

Investigate the Apache Data lab stack, add Spark to our lab, add a data workbench...

ODE Newsletter - February 2021

I'm 7 people into working towards my 100 conversations. It is said that you need to have 100 conversations as you solidify your business / startup idea. So this is where I am, seven conversation in. If you know anyone who works with ocean data or works for a business that has an interest in oceans, I'd love to talk with them.

Given the time restraints of being deep into a large data / database migration project, I consider February has been a good month for conversations. It provided me a good view into the horizon of ocean data. I followed the conversations that were presented to me without me directing the focus. For this is the first month, and I have yet to gain clarity of the gaps of where I need more information. This makes sense given I am at the beginning and don't know what I don't know. Now that it is the end of February I have identified the need to talk with customers of ocean data. This could become a focus for March. The conversations for February unfolded in the following order, with the following summaries and highlights;

PropelICT (https://www.propelict.com/)

I reached out to a past co-worker in a leadership position within PropelICT. PropelICT is an Atlantic Canada e-accelerator for tech startups. The conversation was very encouraging and initiated my application to their April cohort. Looking forward to their support in the coming months (and years).

Highlights: 

• The idea of 100 conversations.
• My first suggested conversation contact. 
• Being a candidate for their e-accelerator.

eOceans (https://www.eoceans.co/)

I spoke with one of the principals of eOceans. Time very well spent, Thank-you! So many details to be digested from this conversation. This organization clearly understands ocean data and where it intersects with social media! A bulleted list seems the best to call out the highlights;

• There are many open standards and organizations working in this space. The data standards seem to be "standardizing" and there are many organizations working toward bringing the data standards together. More open organizations are contributing than the closed proprietary types. CIOOS is the standout for Canada. EU and US are much further down the standards and open data path than Canada.
• Both ends [(data storage and end-points (IoT)] of the data collection are well serviced with lots of business and startup activity. It's the middle were the greater opportunity exists. It's with the data integration with consideration for all the standards and granularity. "It would be nice to dust off a 10 year old data set and be able to easily use it".
• Working with ocean data initiatives is very project based and finding the revenue sources / the business model for an open reference architecture for the digitization of oceans could prove difficult.

Highlights: 

• Many open organizations already working in the ocean data space. 
• The business side of what you are exploring (reference architecture) may be difficult, so much work is project based and gov't funded. A reference architecture seems like an NGO or consortium kind of thing.
• Middle ground of software and data integration could be a big need given my skillset.

Mentorship

Super fortunate to reconnect with an older friend who has loads of experience; small devices, programming, data, startups to a favorable exit, machine learning, etc... many skills that align well with what I am doing. And on top of all this, I really enjoy the meandering conversations we share!

The one area where there is a strong overlap towards my ocean data focus and the mentors previous experience with the integration of data. And yes he confirmed, integrating data from different devices to a common standard is a lot of work for creating a single view into a broad data realm.

Highlight: He agreed to provide me mentorship within this endeavour. So great!

New Brunswick Ocean Strategy: Our Opportunities in the Blue Economy

This was an excellent online conference put together by the Ocean Supercluster. What I did most was listen, and a good thing too... I have so much to learn. I really liked the breakout sessions where there was more individual participation. Some names, and acronyms are becoming more familiar too me. 

Highlight: A small list of contacts I could reach out to. All good!

TechNL (https://www.technl.ca/)

I spoke with one of the leaders in TechNL and we talked about what I am wanting to do with data, in particular, ocean data. The conversation pointed towards two relevant contacts;

• Petroleum Research of Newfoundland Labrador (PRNL) and how they are always focused on innovation within the Oil and Gas.
• OceansAdvance which is focused on the Newfoundland and Labrador Ocean Technology sector.

Highlight: That if I am going to be successful in this endeavour I am going to need partners. The time required for setting up an organization isn't the best place for me to be focusing my time at this stage of the startup. And given the nature of this startup needing to work in the open, the partnership route may be the best way to go...

Canadian Integrated Ocean Observing System (https://cioos.ca/)

So fortunate to have the attention of two CIOOS employees! They were so gracious a provided a broad and deep amount of information regarding the state of ocean data. Super helpful! CIOOS clearly knows the data. The best way to summarize my conversation is by including the important questions and there answers;

With ocean data where is the greatest pain?

Resources as in financial and skills / knowledge.

At the more general project level; governance and the people who know how to organize and stewardship data through its lifecycle. This is more a reference to the industry in general... it's a project issue. And having the ability to integrate with a project that happened years ago...

Do open data standards have an influence?

Absolutely! There are many references to open data. Most of what we deal with are open.

How easily integrated are the existing data sets?

It’s getting better. It can be difficult to get an older data set and want to integrate it. These older sets often lack the granularity or metadata that makes it easier to ingest. There is a definite need here at a project level. Developing an expertise here could become a strong business.

Most initiatives within this space are project based. Which makes it difficult for longer initiatives that have some data sustainability. Rarely are there long term funding initiatives.

Highlights: 

• So many acronyms, references and URLs. The CIOOS folks provided me many references all pointing in the right direction. Reference to some of the ISO standards. 
• The need for better stewardship of data so as data ages it still has usefulness.

Pisces Research Project Management (https://piscesrpm.com/)

Another fortunate conversation with a person deep into ocean data and with the added bonus of being very technical. This was a contact I harvested from the New Brunswick Ocean Strategy Conference. There are may topics I could summarize from this outstanding conversation, much of the information confirmed things I discovered from the previous conversations described above. This is good!

I did pitch my idea about mooring buoys as a fixed points of data collection, and having these buoys like the personalized weather stations that have become so popular. This employee loved the idea.

The exciting part of this conversation was the discussion of the technical stack used within the open data within the oceans sector. It was good to add this to the knowledge I had of the proprietary technical stack used when I was managing the software engineering dept. at Provincial Aerospace.

What is the most common tech stack for Ocean Data?

This person has extensive experience working with Government Organizations and Academics. From what they have seen the most common, and emerging, technology stack includes;

• Python
• Assorted data storage approaches. Often NOT an RDBMS.
• QGIS is common.

These are the tools he finds most effective and common. Using QGIS pushes you into the geo representation of data. Much ocean data requires different kinds of models, more 3d, more oceans… not necessarily geographic, etc.

The ability to prove models with real data is the biggest need from a technical perspective. This is why python has such good traction. It is easy for non-programmers and also rich enough for programmers. A good language for data, and useful across the technical skills working with data.

NetCDF is the most common data-store. Also CSV and proprietary data storage. Remember data people are mostly not programmers or overly technical.

Also take a look at CKAN (https://ckan.org/)

What are people looking for from a technical perspective?

• Proving models with real data.
• Integrating data

Highlights: 

• A deep discussion about the technical stack. The preferred programming languages, data storage, integration approaches, and technical issues.
• Confirmation that integrating data and proving models is an area of software development opportunity.

Lessons Learned

1. A reference architecture for the digitization of oceans is not enough to hang a startup or business upon at this time! Where I do believe it is still a good idea that will form through time. There is so much work already going on for a common open architecture that another doesn't need to be started. I truly believe a reference architecture will emerge, it is a; when it will happen, not if it will happen.
2. There is a big need for technical and software development skills and knowledge in the data engineering space of ocean data. I believe the opportunity exists for a software development / data engineering consulting firm with the specialty of ocean data.
3. The idea of an anchored (or fixed) buoy for ocean data collection is very compelling too me. Kind of like the personal weather station but as a fixed mooring buoy. Anyone who has a mooring buoy could replace it with the data buoy, and have real-time data about the conditions at the buoy in preparation for mooring.

Next Steps

1. March will be the month of broadening my reach. I need to talk with a broader section of people working in the oceans space. I need to find potential customers for the processing and software development in, and around, ocean data. 
2. I need to start building software tools for the processing of ocean data. I need a reference technology stack showcasing our abilities to work with data.
3. I need to start developing an elevator pitch for the ocean data software consulting firm. I need customers and revenue to get the real feedback to focus the business mission.

Digital by Design, Agility and Data Architecture

For 12 months, starting the summer of 2018, I was very fortunate to fill the data architect role for the Government of Newfoundland and Labrador's digital by design citizen facing web portal. An amazing team was brought together and we accomplished an amazing amount of work given the complexity of the environment we were all working. Kudos to the leadership team for seeding the ground and pulling together a diverse and effective group of people.

Being the oldest team member, with 35 years as a technology professional, I noticed a number of items and approaches that I consider the highlights of the project. I call out my 35 years experience because I know success doesn't always happen in a large group of people (with a team larger than 35). A group of strangers doesn't always come together when tasked to ship software on schedule and on budget. The cool part of this project is that the highlights were both technical and project management. In a nutshell, we came together using a scrum model of project management (hosted within JIRA) and architected a microservices technology stack using predominantly Microsoft technologies. The user experience design was exemplary and the software approach stayed aligned with the best of agile practices. We also used a scrum of scrums approach to manage the three distinct scrum teams.

What made this first year of a new project so effective?

The Agile Practices
The team was encouraged to use Agile approaches to successfully ship software. Thankfully, the commitment came from the most senior level and agile workshops were used to align the teams understanding and approach to agile. I consider these three agile practices what kept us all well aligned;

1. We rigorously stayed with 3 week sprints. This was facilitated by the scrum of scrums group and kept us all focused on shipping working software.
2. We embraced jira and stayed true to moving cards. It took a few sprints, as a whole we ended up having all the team members updating and moving cards. This, combined with morning standups, kept the team transparency high and important issues in the open.
3. We always had demo days and retrospectives. This went a long way to keeping us focused and successful. All team members were encouraged to attend the other scrums demo days, this built excitement and kept us focused and moving.

Software Engineering Discipline
Developing software is as much art as it is science. Our team included many accomplished software engineers and this helped us implement features quickly and completely. Kudos are deserved by many on this project team, in particular, one of our technical leads (this is you, Phil) was hellbent and lead through example with two attributes of software engineering that are super important and sometimes missed;

1. We refactored always, no excuses. As a group we were always learning, as implementing features is a relentless teacher. Improving upon our code base through refactoring kept the quality improving, and the bugs low. Even from a data architecture perspective, at the beginning of each sprint we refactored the data tier with the required data changes from the previous sprint. Data tiers often have different heart beats that the middle and user tiers as they are dependent on the legacy systems, which often have legacy heart beats. This is a blog post in itself...
2. Automated testing. We automated whenever we could, we aspired to have automated tests with coverage to all our code. We got close by using frameworks and having a test first mind set. And don't underestimate how effective existing testing frameworks can be applied to the data tier.

Architecture was collaborative 
All architects were encouraged to contribute and discuss, we were always white-boarding and soliciting feedback. This kept the architecture strong and well understood throughout the team. And because we had a shared understanding of architecture the refactoring was reduced. All good...

Ocean Sector Specific Search

I've recently finished building an industry specific search engine. The primary use case is to drive international and domestic business traffic to the Canadian websites doing business within the oceans technology and innovation sectors.

From a technology architecture perspective we built a search engine for the Canadian oceans super cluster initiative where all components run, and are based, upon Canadian assets hosted in Canada. We seeded the search engine using the URLs for all the organizations identified as participants within this economic sector. The indexing process analysed each URL and followed all links up to two hops deep. All the identified URLs were scored using a web graph and the top pages were indexed.

The architecture decisions

The NELK stack became our back-end infrastructure.

A number of important architecture decisions were made early on as the project was detailed. Mostly decisions were made to support the technologies that the small team was already familiar. And if the team wasn't familiar, we chose technologies that had the most industry support and local resources in our personal networks so we could help out if we needed. We ended up having Nutch feeding the ELK stack using Wordpress for the UX. In the project it became known as the NELK stack.

• Nutch - for web crawling and first round of web page extraction and cleanse.
• ElasticSearch (ES) - as the search engine / data manager
• Logstash - as the data transform and load.
• Kibana - as the administration / developer console

Crawling the web with Nutch
We ended up using Nutch to crawl the internet for ocean sector specific web pages. We also needed to integrate with ElasticPress so the broader ecosystem search included the contents of our websites Wordpress database. To do all this we ended up using Nutch 1.15 for it integrated best across our technology stack. We used the Nutch recommended approach seeding, ingesting, fetching, and duplicate removing as we prepared the data for export to ElasticSearch. Due to versioning issues we exported the Nutch database to CSV before importing the data. For the first load of data our use of Nutch created the following page loading metrics;

• seeded with 2612 domain names
• removed 709 duplicate or in error domain names
• identified 86872 candidate webpages 
• fetched the 29323 most relevant web pages (based upon web graph algorithms)
• indexed 29270 pages into ElasticSearch

Loading data with Logstash, inspecting the results in Kibana
We used Logstash to bring the Nutch exported CSV data into ElasticSearch. Coding up the logstash job was fairly easy, the most important aspect was choosing the correct logstash filter. It was better to use the dissect filter rather than the csv filter. More on this in a later post. In the end, I was amazed with how quickly Logstash loaded, and ElasticSearch indexed, all the data.

Once all the data was loaded into ElasticSearch I used Kibana to confirm data was correctly loaded into the data repository. Kibana has a very intuitive interface and creating filters and running queries to confirm the successful loading of data was straight forward. I look forward to using Kibana to manage the repository and create meaningful dashboards.

Once we had the back-end built and loaded with industry specific web pages we still needed to find the correct tool-set to provide a query interface within a Wordpress template and to integrate with the organizations identified in the Wordpress database. We wanted the ecosystem search to include both what we had indexed from the internet and the organizations listed in our directories database. The solution ended up using two solutions;

• The ElasticSearch (ES) PhP library which provides a mature (and easy to use) set of features to build your own interface into ES using PhP.
• ElasticPress which allows automated ElasticSearch integration with a wordpress database.

The Wordpress / PhP tools for integrating with ES are very effective. ElasticPress has automation that keeps it up to date as changes are made within the Wordpress database. The ES PhP library has a robust set of features that makes for easy coding and kept search performance very high. Even with large query results the ability to traverse the result set forward and back was easily handles with features available in the PhP library.

In conclusion, using Nutch with the ELK stack provides for a very strong search engine that integrates easily with Wordpress on the front-end. The learning curve for this approach was not overwhelming and whenever challenges presented themselves the online groups help us resolve issues within days.

Special thanks to the team put together by Triware Technologies. Without all the other technical people, analysts, business people, data entry, project managers, Oceans Advance, ACOA, Ocean Super Cluster, ElasticSearch support, Azure support, and those clearing the way... none of this would have been possible. Thank-you!

Seeking New Opportunities

TLDR;
Veteran technology professional seeking new opportunities. If you are requiring 35 years of career success in the software technology realm that spans startups through to large enterprise environments, then I'm your guy!

I have tonnes of experience and I can hit the ground running. I can work as a senior project manager, an enterprise solution architect, as a scrum master and build a team focused with agile approaches, I can design databases and related structures for your business analytic projects, and I can own your Business Intelligence initiative. I can provide strong, and proven, leadership. And if need be I can occupy the technical director level. You will find I provide great business benefit and good value, my experience provides the ability to save you more than I would cost.

A history of project success
I'm back to consulting in the technology realm. Being a technology consultant has provided my clients, and myself, many project successes. These successes have been both with technology startups and with medium to large business environments. For more details describing some of my project successes please read these two posts describing projects I have managed and provided technical leadership over the last decade;

Increasing Access to Education - this collection of eight projects helped CLEBC become one of the globes premier legal educators.

Career success in three year cycles - These four major corporate initiatives leveraged all my abilities to help PAL into their next level of technology capability and realized business value.

Where I can help the most

I can have an immediate positive impact to any technology initiative within large and small organizations. This success can come with startups and enterprise environments, or something new that can leverage my skills, knowledge, and experience.

There are five roles to where I can bring the greatest immediate business value;

1. Enterprise and Solution Architecture - The solution side of designing technical architecture has most often been my preferred role within a software development initiative. I've done this for small startups and large enterprises. Good solution architecture creates a better technical solution that saves development costs, improves quality, and ensures alignment with business needs and the other technologies within the business ecosystem.
2. Senior Project Management and/or Managing a Software Development Teams - Through time I have managed many projects with software development teams varying in size from 3 to 30. I have proven track record of bringing projects to completion on-time and on-budget. I seriously enjoy assisting a team of technical people to ship software.
3. Data Analytics Project (Architecture and Team Management) - The B.Tech undergrad degree I completed in the 80's was focused on database management. And since that time my career has had data as its foundation. I do very well with data management [including the design of data structures and related communications (read API's)]. I can also work well within big data projects as my experience with big data goes back to the 1980's. Read one of my big data posts from a few years back to get a sense of this capability; Big Data; Similarities and Differences.
4. Technical Mentorship - I'm an educator and have experienced many startups during my time in Vancouver. If you want to discuss the technical side, the team management side, and/or the development methodology to an innovation project (startup or otherwise) I can help here.
5. Innovation - Many times in my career I have taken business strategy and made it happen. If you have a business strategy that requires software innovation I can make it tactical and implement. 

I'm willing to travel

A single flight from St. John's Newfoundland is my preference. I would also be very interested in consulting work in Vancouver (my home town). I have family there and could easily have all the amenities I require for extended working stays. In a previous blog post I describe how I consider the size of the St. John's marketplace to be 40 million people. I also need to consider the St. John's market to be a single flight away as I seek out new challenges and opportunities. My list of cities I will immediately consider consulting opportunities, include;

1. Halifax: it's a morning flight away, and can be there and back including a full days work. I'd also stay for a few days if required.
2. Toronto, Ottawa, Montreal: single 3 hour flight, couple of days then return home for remote working
3. Vancouver: longer stays and longer aways... I have family in Vancouver, so it would be a very nice approach to working.
4. London, England: An outlier, but... It would be nice to work in the EU and I have a British passport so it would ease my travel and work permitting.

One personal constraint
To be succinct, I require work-life balance... mostly it is about having time to care for middle-school age children and aging parents. This means I am available part-time or full-time with loads of schedule flexibility.
