Totally Free

On occasion, I have the good fortune of receiving random photo’s from one of my colleague’s at the University of Alberta.  I am pretty sure he does not read my daily posts but his pictures are sure helping with the ideas so I hope they keep coming.

On the weekend he was strolling by a lake and noticed this seaweed floating by.  What struck him was how it appeared totally free from restraint.

free leaf

Can anyone be totally free?

This thought put me in a philosophical mood.    Is anyone free, can we ever be truly free?  Is even this seaweed blissfully floating on the lake without a care in the world, is it even free.  There are the constraints of gravity, the whims of movement are controlled by  external forces, wind,  water etc.

I guess to build the discussion we need to consider the meaning of the word.    My favorite description of freedom is ” exemption from external control, interference, regulation, etc”

In that context is “total” freedom possible,  I wonder, and not to be morbid, but in the context of that definition for humans maybe freedom is only truly achieved in death.  Actually I think not, read on.

How about you are as free as you feel?

That being said though I am a true believer that we all control our own freedom.  We are accountable and in control, in fact no one and nothing can exert control over my mind, my thinking – they are mine.  I can be impacted by external actions (the wind and the water) and behaviors (other humans actions)  but how I react, that is mine and mine alone.

I started to form this philosophy more strongly after reading Mans Search for Meaning by Viktor Frankl in which he uses his experiences in a German concentration camp (in the 1940’s) as a basis to explore Man’s search for Meaning.

Usual Disclaimer and Wrap Up

Believing we are totally in control (i.e., free) is an excellent philosophy to hold, however, I would be dishonest if I did not say that even believing I am completely and solely in control of myself, reality does intrude (oh darn)!

Today’s post is something to think about and possibly to aspire to (your choice).  I would definitely postulate that owning your life and being personally accountable is better than not.

 

 

Reminiscing on Life

Every once in a while, things that happen today remind you of the past.  This could be any kind of memory, pleasing, unpleasant or just neutral.

Yesterday I had one of these experiences,  took me back twenty-five years.  My wife was going through boxes of children’s books we have saved for our grandchildren sorting and preparing to deluge our offspring with boxes of books for their child.

In one of the boxes was a story written as a school assignment,  by our oldest daughter in 1990.   On re-reading the story it really highlighted for me how perspective of the moment really matters.  Back then I was a busy young professional with a growing family and multiple school age children.

Today I was amazed by how insightful and mature my daughter was at that young age.  It was a simple story about events in my daughters life written as a fairy tale.  With that part of my life in the past, that is I am no longer living it, the story took on a whole different perspective and the ending, well, I just had to laugh out loud.

And the point!

Past moments in your life can be viewed very differently with your today’s lens.  It’s fascinating to me how your current state, environment, events effect how you view the things that transpire around you.

In this case, having passed through the child rearing years reading this piece of the past had a much greater emotional impact than it did twenty-five years ago when I was living it, but I recognize I was not really in the moment at the time fully experiencing it.

The point is, whenever you can try to pause and take time to smell the coffee, you don’t really want to regret it later.

Artificial Intelligence

Saw a great movie a couple of weeks ago called ExMachina.  It was an exploration of the concept of artificial intelligence.  That is intelligence made or produced by human beings rather that produced naturally.

Allan Turing was a British scientist considered by many to be one of father’s of computer Science.  Among a number of significant achievements before committing suicide Turing  introduced what is now known as the Turing Test in a paper he wrote that was published in 1950.

In essence he proposed that if a human examiner was set up to converse with other humans and machines (through the same interface) when the conversation with the machine could not be identified as such, the machine could be deemed intelligent.

In ExMachina the story was a variation on the Turing Test.  The tester had only one subject to examine, an android.  In a twist the builder of the android designed the test to see if the machine could manipulate the tester.

In 2014 PrincetonAI’s submission to the annual Turing Test (a machine called Eugene Goostman) fooled 33% of the judges.  There is of course controversy associated with this result – did the developers games the system?, Was the test too easy?

Regardless of the questions, Artificial Intelligence is clearly on it’s way.

 

Surfing the Web

Yesterday’s post covered the basic concepts of the most popular part of the internet, that is the world wide web.

One of the most commonly used forms of viewing data from one computer on another device connected to it via the internet is through an application commonly known as a “web browser” or “internet browser” or just “browser”.

The browser is just a software application that runs on a computer, phone, pad or other similarly functional computing device.  Most commonly the browser connects to a software application on another server via the internet.  The sending application is generically called a  web server.  There are a wide variety of specifically branded web servers with names like Apache and Internet Information Server (IIS).   They all perform the same basic functions but have different features performance attributes and costs to acquire and operate.

The data sent from the web server computer is in a standard format (there are a variety of these) and the browser knows how to interpret the data it gets because it understands the structure of the data because of it’s standard formatting and codes that tell the browser how to display and interpret it.   The displayed data is called a web site.

You can see the term world wide web led to a number of related naming conventions – web site, web server, web browser as these all depended on the world wide web to perform the functions for which they were intended.

Surfing the Web

Surfing the web became the commonly used term for viewing various different websites in your browser.  This could be via multiple searches for specific information or by using links from one site to another.

Surfing has become a popular pastime for both entertainment and gathering knowledge.  In one sense the internet is just the worlds largest library (although I would not believe everything I read there, except this blog of course).

Not Just About Websites

It is important to note although the most common use of the internet is via web sites;  the basic concept of the internet, i.e., two or more computers connecting and exchanging information/data in a way each understands and can interpret,  enables much more than just web site functionality.

Remote connections to computers, e-mail,  file transfer protocol (FTP), voice over IP;  are just a few of the other common functions that can be executed using an internet connection.

 

World Wide Web- Spiders Beware

Really what is the internet?

The internet is a simple term referring to a vast network of computers that communicate with each other by a common set of standard communications protocols.

Each device on this network has a unique identifier (Machine Access Code also know as the MAC address).  All end points on the internet are identified by up to 12 numeric digits made up of four groups of three in the format xxx.xxx.xxx.xxx.  This is called the Uniform Resource Locator (URL).

When combined with the Uniform Resource Locator (URL) one device with a unique MAC address can access another at it’s associated URL and send information to it.  The response to the originating device’s MAC address (via it’s associated unique URL) creates a two way data exchange between the devices (a conversation if you will).

A word with an associated 3 character extension (called a domain name) can be associated with a URL so you don’t need to know the actual URL number,  just the word.  The three letter extension is used to identify the type of domain (i.e., .com – commercial, .org – organization, .ca – Canadian, etc)

Note:  This is changing and the extensions are becoming unrestricted in length and more informational (e.g., .Deloitte) , this is a change to domain names you will see introduced over time.

What about the world wide web (www)

In addition to the three letter extension at the end of a domain name (suffix) there can be a descriptive prefix called a sub-domain in front.  This would be formatted for example as xxxxx.domain.com.   This sub-domain allows for access to a number of actual websites associated with the same main domain’s URL but differentiated in location within the main domain URL  (actual web address) by the prefix.

In the beginning public internet domain names used the prefix  www. (world wide web).   Overtime the need to use www. sub-domain in front of your public website on the internet has generally been dropped.

Why post about the internet today?

It started with this picture a colleague shared with me this morning.  It really resonated for me as my current career is very much focused on the “web” (and his too) and it just resonated with me.  Hence I was prompted to do a short post on the background basics of the convoluted web we call the internet.

Save your Vision – Consider Transition lenses

I recently went for my annual eye check, all was fine but I got an updated prescription – my vision is a little weaker.

This led me to Lens Crafters because they had a 50% off sale.  I do wonder about that though.  They will sell you lens for $750 regularly but twice a year they will sell you those same lens for $325.  Tell’s you something about their mark-up.  Also makes me wonder why anyone would buy lenses at any time but during their semi-annual sale.

Why transition lenses?

I live in the most northern city in North America with a population over 1 million.  This means the sun is low on the horizon at sunrise and sunset and this can play havok with your eyes, particularly when driving.  Often I forget my sunglasses and I cannot put them on while driving as that is distracted driving and it is illegal.

So this time I purchased transition lens which automatically darken as the surroundings get brighter.  Instant sunglasses.  For years I thought this was a gimmick and a waste of money (these lens cost more) but my wife has been using them for years and finally I was convinced to give it a try.

Unwanted Advice

I am a firm believer that the only kind of advice is unwanted advice (by definition) but I am going to go ahead anyway.  If you wear corrective lens seriously consider getting transition lens, they are fabulous.

Food Additives and A Funny Story

I found out today that many breakfast cereals  (including Cheerio’s) contain Trisodium Phosphate (TSP) as an additive.  I believe this addition is like adding baking soda.

What is interesting about this is there is a popular cleaning agent branded TSP which also contain trisodium phosphate and some other stuff.  This product is really good for cleaning painted walls as it generally does not affect the paint but is good at dissolving greasy fingermarks and the like.

The Funny Story

The funny story for today’s post is not that TSP is used in breakfast cereal manufacture (that’s more sad than funny.)

In the 1980’s when my children were all under 10 they all desired we acquire a dog.  I was strongly against this and asked my wife not to get a dog.

So, my oldest daughter, unbeknownst to me,  saved up her allowances, gifts and other sundry funds, found a breeder and bought a pure bred Sheltie (Shetland Sheep Dog).   When my wife and daughter brought the dog home I of course protested and my wife clarified that she did not get a dog, as I had requested of her, rather my daughter got the dog.  Bazinga on me.   The dog had been named by the breeder and was called Tia, which was Spanish for Aunt.

I will continue with my funny story but would like to note that Tia was a wonderful dog and the whole family (including me) came to love her very much, kudos to my daughter and sneaky wife.

Once day I bought some TSP to use as a solvent to clean the walls of our home.  As I dipped the sponge in the bucket and began to wash the walls my children (all three) appeared and asked what I was doing.  “Just washing the walls with TSP” I said.  At once they were all concerned and disgusted,  ” Dad” they yelled ” How can you wash the walls with Tia’s pee,  that’s disgusting”

Of course I had to clarify for them and soon all was understood, but I still chuckle over this story.  If you say”TSP” out loud you will see it does sound very much like Tia’s pee.

Enjoy your cheerio’s!

More about RRSP’s

In my series of posts about retirement planning,  back at the beginning of August, I reviewed pensions, registered accounts, income funds and life annuities.

Today I am going to drill down a bit more on Registered Retirement Savings Plans (RRSP’s)

Currently you can contribute 18% of your income to a maximum of $24,270 (the limit can change each year).  The thing to note here is the Canadian Revenue Agency (CRA) will calculate your next years contribution limit each year when you submit your tax return.  The calculation for the upcoming year is based on the income reported on the submitted return.  Or more simply put, when you submit your 2013 tax return in April 2014, on the confirmation the CRA sends you back they will indicate the 2014 contribution limit (calculated based on 2013 income).

Some things to note:

– contributions to employer pension plans that are not taxed are counted toward the limit (say you contribute $6000 to the company plan through payroll deductions and your Registered Plan  limit was $24,000 than you only have $18,000 room left for your personal RRSP.  It does not matter if the employers plan is defined contribution or defined benefit.)

– additionally unused amounts from previous years are held over and accumulate.  So you don’t loose unused contribution room, it just adds to the next years 18% max $24,270 calculation,  making the contribution room higher.

Although you can calculate the maximum contribution limit the best way is to let the CRA do it for you.

Reasons for Contributing

As noted in my previous blog you defer taxes on the refund you get.  And you get the investment growth on the amount you contributed.

Another key value of your RRSP contribution is the tax refund you get, that is basically calculated as your marginal tax rate times the amount contributed.  You can use it to buy things (e.g., payment toward a new car) or you can invest it.

For future use (for example when you retire), investing the tax refund works best , that being said though using the refund to buy something you want now (a little luxury), but were not able to save up enough during the year, can be appealing too.

The bottom line is to make a conscious and informed decision  of how to best use your RRSP tax refund (basically invest or spend) in the context of your overall financial plan.

Contribution Strategies

Given unused contribution room accumulates in cases where your income is rising over time you can benefit by for example contributing extra savings to a TFSA initially instead of an RRSP and building your RRSP contribution room along side your income growth year over year.  Then at some point,  make a big contribution to your RRSP.  At this point assuming your income has put you in a higher tax bracket this maximizes your refund (which is based on your marginal tax rate).   The balance here is not to wait too many years as the value of the refund is having it to spend or save.

This strategy balances the contributions to both of the key Canadian savings vehicles that help reduce your tax burden (i.e., RRSP and TFSA).   The values and benefits of TFSA versus RRSP will be explored more fully in a future blog.

Film Comments – “Sunshine on Leith”

My wife and I watched the Scottish film “Sunshine on Leith” last night.  For us it was a hidden gem.  Not a widely publicized film in North America, although it screened in the special presentation section of the Toronto Film Festival in 2013.

It only went in to theatrical release in North America in early 2015 and DVD release is just out.

Leith refers to a district to the north of Edinburgh, Scotland lying at the mouth of the Water of Leith.   The movie is taken from the stage musical in which a story is built around the songs of the Scottish pop group The Proclaimers.

Great story, good music and after seeing the film I definitely will visit Edinburgh, what a beautiful city.

Not a Review!

This post is just about me sharing my experience about the film, as both my spouse and I really enjoyed it.  First it’s a real life drama, feel good entertainment and unlike many musicals the songs are not constructed to support the story, in fact just the opposite.

General Observations about Movies

Thinking about today’s blog topic I wondered what are the attributes of a good movie.

Obviously the entertainment value is very targeted to the likes and dislikes of the viewer, that being said I find it really interesting that the ratings on film review site Rotten Tomatoes often (like 9 times out of 10) match my own thoughts.  Of course the type of movie I watch at any time is a filter for choosing, that is a thriller, romance, heavy social theme, etc.   But, if the genre appeals to me I find the Rotten Tomatoes rating is often on target.

My conclusion would be that basic attributes of a good movie; actors, story, cinematography, etc  are good measures and these things form the underpinnings of the overall average score of a film on Rotten Tomatoes.  Thus on the whole the ratings provide a good indicator of whether the movie will be enjoyed or not.

Sunshine on Leith scored 92% on Rotten Tomatoes.

Breaking Down Taxes

Taxes are what we pay to our governing body to cover the cost of the provision of common services, common that is to everyone one who comes under the control of that governing body to some extent (in some cases that includes visitors who don’t necessarily pay taxes for services they receive when visiting) .

To make that less general, say you live in a city and there is an elected group (the city counsel) that oversees the cities operation.  That is the governing body.  You pay them to provide and manage the common services for the people living in the city (everyone under the control of that city council).    In this case common services are things like police, recreation centers, parks, etc.

In reality most people are aligned with a number of governing bodies (e.g., cities, provinces, countries)and pay taxes to each in a number of ways and receive different services from each (in some cases overlapping services).

Are Taxes Fair?

If everyone received the same level of service and paid the same amount taxes you could argue this was fair.

However, you could also argue individuals with more resources (i.e., money) should pay more and support the services they use as well as some of the services those with less money use.  This kind of pay what you can afford thinking has a number of supporters who argue it is fairer than equal distribution of cost and usage.

There probably are those who argue the “you should only get what you pay for” approach as being the fairest.  That is if the park cost $100 to build and there are 10 residents they all pay $10 taxes and get to use the park exclusively 10% of the time.   England briefly tried a variation on this approach with a poll or head tax – every man women and child paid the same basic tax.  (no surprise this did not work out well)

And reality strikes home!

Of course in the societies which we live it is not practical to match cost to service received and this is even more complicated by the multiple government jurisdictions we generally support.   So we practice the principle that those who earn more pay a higher percentage of the taxes (theoretically if you earn more you can afford to pay more).

Say you go to out to a restaurant for dinner with your parents.  If your parents pay the bill you get a free meal, odds are though they wanted to pay for you.  I will assume they can afford it and probably wanted to cover your meal cost to help as you have less resources than they do (not because of ability but rather probably due to age, experience and opportunity). They know if the situation was reversed you would pay.

I am not sure those that pay a higher percent of the tax bill giving others a “free meal” want to do it, but the concepts do have some parallels.

And the usual disclaimer and caution

Effective societies operate on the principles of collaboration and charity, not equality (one of the key reasons communism does not work .   The key consideration though is balance.  That is everyone is equal probably does not work but nor does overtaxing those with more resources.  The tax scenario works best if balanced for all parties.

A parting thought (and great book for you to read if you have not already done so)  in the book “Atlas Shrugged” author Ayn Rand creates a world where the differences before those that can and do and those that do not is exaggerated.  Basically balance does not exist those that cannot feed off of those that can.  Those that can succeed drop out of the society, no longer supporting the government (they had enough because the balance was off) and the result – I won’t give away the ending of the book but you can probably guess.
