Universal Design: Make it a Core Competency in Industry and Trade

  • Architects
  • Civil Engineers
  • City Planners
  • Interior Designers
  • Construction Project Managers
  • Product Designers

Should all be required to have Universal Design as a part of their curriculum of their respective College or University and let us be frank. Those same  public institutions are not as “accessible” as we might think they are.

We have standards for a reason. There are most industries that regularly handle the Critical Path to achieve a solution that is a best for a scenario.

We’ll see how things unfold with SidewalkToronto and they are still in the very early stages. Hopefully their efforts will be adopted globally, not just Nationally or within the City.





Building channels of data…

Data can and SHOULD have an expiry date outside of our sphere of control. The European Union has tackled this. The Canadian governments have attempted to deal with this.

By using Open Source, and requiring all publicly funded software systems that handle people’s personal data should be required to use Open Source Software and Data Principles is one way.

This has been quietly happening in many governments and corporations.

Now the conversations you have are yours to manage even when you’re chatting. This is why I use Signal

Facts and Statistics

Statistics Canada’s Participation and Activity Limitation Survey (PALS) provides information on the prevalence of people with disabilities, their employment profile, education, their income, and their participation in society.

Total Number and Percentage of People with Disabilities in Canada •Approximately 3.6 million people in Canada have disabilities, representing 12.4 percent of Canada’s population.

Total Number and Percentage of People with Disabilities in Ontario• Approximately 1.5 million people in Ontario have disabilities, representing 13.5 percent of Ontario’s population.[1]

Disability Rate Increases with Age• Of the total Canadian population in 2001, 12.4 percent have a disability. National statistics indicate that 41 percent of people aged 65 and over have a disability, while among those aged 15 o 64, 10 percent have a disability. Of the total population of Canadian children aged 0 to 14, 3 percent have a disability.

Projected Statistics on Aging Population• Projections show that by 2021, seniors with disabilities will outnumber 25- to 64-year-olds with disabilities. In 2026, the majority of people with disabilities will be 65 years of age or older—some 3.05 million people.[2]

Education• Approximately 40 percent of adults with disabilities have a post-secondary education, compared to 48 percent of the non-disabled population.

The following table indicates the highest level of educational attainment for adults in Ontario ages 15 to 64:

 With Disabilities

 Without Disability

298 030 (37%)

1 606 550 (24%)

626 760 (9%)


136 310 (17%)

1 179 600 (17%)


93 700 (12%)

1 506 710 (22%)

• More women than men have completed college or university in the non-disabled population (42 percent versus 37 percent, a 5 percent differential), as well as in the population of people with disabilities (31 percent versus 25 percent, a 6 percent differential).

Employment• Over half (54 percent) of working age adults with disabilities are either unemployed or not in the labour force, compared to less than a quarter (24 percent) of working age adults without disabilities.[3]

• The employment rate for people with disabilities is 41 percent, compared to 76 percent for people without disabilities.

• The unemployment rate for people with disabilities (26 percent) is over 5 times higher than the unemployment rate for people without disabilities (5 percent).

The following table indicates the labour force activity for adults in Ontario, ages 15 to 64:

 With Disabilities

 Without Disabilities


336 120 (41%)

5 175 000 (76%)

Unemployed/Not in the work force

443 040 (54%)

1 610 070 (24%)

Trades certificate or diploma

36 780 (5%)

• A breakdown of the results by gender for Ontario adults indicates that 45 percent of men and 38 percent of women with disabilities are employed, compared to 81 percent of men and 72 percent of women without disabilities. This contrasts with the higher post-secondary education of women with disabilities.


• Total income is defined as the “total of income from all sources, including employment income, income from government programs, pension income, investment income, and any other money income.”

• Ontarians with disabilities reported an average income of $22 543, compared to $34 144 for the non-disabled population, a difference of over $11 000. Ontarians who have disabilities have an average income that is less than a third (33 percent) of the average income of people without disabilities.

• Nine percent of adults with disabilities have a total income of over $50 000, compared to 21 percent of the non-disabled population. Of the adults with disabilities who have incomes over $50 000, 14 percent of men have a total income of over $50 000, compared to 5 percent of women.

• Eighty-four percent of women with disabilities and 65 percent of men with disabilities reported income of less than $30 000.

• Forty-six percent of adults with disabilities in the labour force make less than $15 000 a year, compared to 32 percent of people without disabilities. Just over half (56 percent) of women with disabilities in Ontario’s labour force have a total income of less than $15 000, compared to approximately a third (33 percent) of disabled men.

The following table indicates the total income of adults with and without disabilities in Ontario, for ages 15 and over:

[1] Figures taken from Statistics Canada, Participation and Activity Limitation Survey (PALS), 2001, released in September 2003. Previous figures of 1.9 million Ontarians – 16 percent were taken from Statistics Canada, Health and Activity Limitations Survey (HALS), 1991. The difference in numbers can be partly attributed to a new survey methodology (e.g., PALS 2001 may have left out a substantial number of people with milder disabilities who had been included in HALS 1991) and to a new survey population (e.g., HALS 1991 included people living in health-related institutions and in the Yukon and Northwest Territories, while PALS 2001 only included people living in households in all provinces). Changes are explained in more depth in A New Approach to Disability Data: Changes between the 1991 Health and Activity Limitation Survey (HALS) and the 2001 Participation and Activity Limitation Survey (PALS) from Statistics Canada, available online at www.statcan.ca/start.html.

[3]”Not in the labour force” includes students, homemakers, retired workers, and seasonal workers in an “off season,” and people who cannot work because of a long-term illness or disability.


Essentially this is the point of concern in Ontario. With the occuring review of legislation regarding accessibility of various locations around the province which involves the following measurements for the size of the population who are “People with Disabilities in Ontario” as 1.5 Million people or 13.5 % of the total population of just over 12 Million (2011 Stats Can).

(1)Total Number and Percentage of People with Disabilities in Ontario• Approximately 1.5 million people in Ontario have disabilities, representing 13.5 percent of Ontario’s population.[1]

This legislation doesn’t affect this group of 1.5 million people, it affects everyone of us in Ontario.

Disability doesn’t discriminated and anyone can become disabled. 

I will be updating this note and sharing information through my website(s).

Maker Movement is here to stay…

and truly it has always been here. More recently it seems to be coming into broader awareness and that’s a good things.  It is when we collectively come together to build and improve our communities at the grassroots level, do we see the most progressive and productive processes and policies arise among the community because they all collectively are interested in a Best for All choices that support and advance everyone’s interests.

We have interests, skills, abilities, talents and gifts. How we express them in the world is how we give back to the world that we live in and on.

We all have the ability to create and contribute and give back to our community that we live in.

How, When, Where and What we do  — be aligned with our personal peace and for the greatest benefit of all including yourself.

A vision of…

what the space for The Source Lab would look like.

First off it is a Lab, laboratory. A laboratory by definition

A laboratory (CommE /ləˈbɒrətri/ or /ləˈbɒrətəri/, AmE /ˈlæbərətɔːri/; informally, lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.

Barrier-free, Universal design, Safe and Open. Is it possible?

In an interview with an O/S2 magazine back in the day, Mike F. Cowlishaw, the father of REXX, said that he always preferred to hire electrical engineers because they designed their solutions keeping in mind minimal prototyping was available. As where, software engineers just kept ploughing away on problems and iteratively improved their code. Programmers from a hardware background developed more sound code their 1st go-round or more frequently than their purely software oriented/taught peers.



So you want to get into “mining” cryptocurrencies?

You’ve been hearing the buzz for a while now. Bitcoin, and there’s a whole slew of others, well because that’s just what happens with what appears to be a great, no wait, an amazing idea, generate your own money by becoming involved in Bitcoin “mining” or any other cryptocurrency for that matter.

Over on Bitcoin.org‘s site they list the minimum requirements as follows:

Minimum Requirements

Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.

  • Desktop or laptop hardware running recent versions of Windows, Mac OS X, or Linux.
  • 145 gigabytes of free disk space, accessable at a minimum read/write speed of 100 MB/s.
  • 2 gigabytes of memory (RAM)
  • A broadband Internet connection with upload speeds of at least 400 kilobits (50 kilobytes) per second
  • An unmetered connection, a connection with high upload limits, or a connection you regularly monitor to ensure it doesn’t exceed its upload limits. It’s common for full nodes on high-speed connections to use 200 gigabytes upload or more a month. Download usage is around 20 gigabytes a month, plus around an additional 140 gigabytes the first time you start your node.
  • 6 hours a day that your full node can be left running. (You can do other things with your computer while running a full node.) More hours would be better, and best of all would be if you can run your node continuously.Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running

Line 2 is the bomb.  145 gigabytes of free disk space, accessible at a minimum read/write speed of 100 MB/s.  Yes you read that correctly. Enough space for an operating system. I will get back to that later.

200 Gigabytes a month. So over an average 30 days that’s 6.66* Gigabytes per day outbound.

Just a few thoughts for now. Will add more later.


—Update March 14, 2018

Maybe you do not want to do so much “heavy lifting” to get into Bitcoin and cryptocurrencies.

Here’s one possible option I recently was told about.
