FoundationAndEmpireFoundation and Empire is the second book in Isaac Asimov's classic Foundation Trilogy, advancing the story of The Foundation - the civilization founded by Psychohistorian Hari Seldon in order to mitigate the collapse of the galactic empire and shorten the thousands of years of anarchy he foresaw following.

The book is divided into 2 stories: "The General" and "The Mule". Story 1 is interesting but unremarkable.

"The General" details a power struggle between the galactic emperor and Bel Riose - one of his generals. It is hundreds of years after Seldon's death and the  empire has all but collapsed, as he predicted. Riose believes he can thwart Seldon's plan by attacking the Foundation. But he is only one man and Seldon's plan relies on the collective actions of the quintillions of people in the galaxy being more influential than anything that one man can accomplish. In the context of history, it does not matter what individuals do. The universe will move forward regardless. This is a basic assumption of psychohistory.

However, the that assumption falls apart in the second half of the book.

In the second story, we are introduced to The Mule, a powerful mutant born with the ability to control minds. His powers are so strong that he can affect galactic history by himself. This disrupts Seldon's master plan and allows The Mule to begin conquering the galaxy for himself.

The Foundation falls to The Mule; but, when the Mule learns that Seldon established a Second Foundation at the other end of the galaxy, he sets out to find and destroy it. Meanwhile, Foundation loyalists also seek the location of the Second Foundation, so they can warn it about the Mule.

I like how the two stories conflicted with one another. On the surface, they are only slightly related and separated by hundreds of years, but they show both the strength and weakness of math, science, and statistics. The first demonstrates how meaningless a single person, no matter how powerful or how ambitious, can affect a galaxy with quadrillions of people. The second shows exactly the opposite. The Mule's power is strong enough that he disrupts Seldon's entire plan. Further, The Mule's plans are thwarted by a single person.

It is this contradiction that makes Asimov's story so compelling. He takes us in one direction and makes us feel comfortable; then destroys all our assumptions.

AnimalFarmMr.  Jones was a lazy drunk and exploited the animals at Manor Farm. So, the animals, inspired by an eloquent speech by the aging and respected pig Old Major, decide to drive out Jones and take over the farm for themselves. They establish a new government, based on seven commandments of "Animalism", written on the side of the barn, that purport to protect the rights of the animals. 

It isn't long before animals are vying for power and exploiting that power once they have obtained it. The pigs are the most clever, so they take control, and end up revising each commandment to their advantage, grabbing more authority for themselves and becoming more and more like Mr. Jones and other human farmers as time goes on.

The other animals eventually find themselves as oppressed by their new pig overlords as they were by their former human masters. After numerous lies, deceptions, and thievery, the pigs modify the final commandment from "All animals are equal" to "All animals are equal, but some are more equal than others". The citizens of animal farm realize too late that they have traded one master for another equally bad one.

Animal Farm is George Orwell's first great work of fiction and it endures over 70 years after its initial publication. Orwell originally wrote the story as an allegory about the Russian Revolution and how Stalin eventually twisted its goals to his own ends; but Animal Farm is ultimately about how absolute power corrupts absolutely and this lesson can be found in any part of the world or political spectrum.

Napoleon the dictator pig uses many strategies to maintain control - from repeating lies that draw his enemies in an unfavorable light to using violence to suppress any voices. It's frightening how much these tactics are still used successfully today.

Orwell followed up Animal Farm with his classic 1984, another dystopian novel with a similar theme about the corruption of power; but Animal Farm does so more subtly, without the need for a closing speech to explain the methods and motivations of the ruling class. Animal Farm is shorter, but more imaginative than the later work. Animal Farm is a simple fable with a simple plot packed with symbolism. The characters are based on real figures of Soviet Russia (Old Major = Karl Marx; Snowball = Leon Trotsky; Napoleon = Joseph Stalin; Mr. Jones = Tsar Nicholas II), but the story works even if the reader is unfamiliar with that history.

TheHobbitBilbo the Hobbit was content with his life in the Shire when the wizard Gandalf showed up with 13 dwarves, who were told that Bilbo was an experienced burglar and would join them on a dangerous journey to steal back a treasure from evil dragon Smaug.

Bilbo had his reservations, but he also had a wanderlust that overcame his desire for comfort; so, he agreed to join the dwarves on their adventure. They set out across Middle Earth, battling man-eating trolls and man-eating dwarves and man-eating giant spiders before confronting the man-eating dragon surrounded by his mountain of treasure, stolen from the nearby towns he terrorized and destroyed.

The Hobbit by J.R.R. Tolkien is a delightful fairy tale of an odyssey across a magical world filled with fascinating creatures. It is a charming story in its own right, but its greatest contribution is that it introduced us to the world of Middle Earth, a mythical land that later became the setting of Tolkien's classic Lord of the Rings trilogy.

The Hobbit is much lighter than the later trilogy and can be read to and by most children. Yes, there are life-threatening dangers, but many of these are a bit silly and the party often overcomes them in humorous ways.

The story and characters of The Hobbit have become so familiar to us, that one might expect this story would become tiresome. But Tolkien never allows this. He brings us on a remarkable journey with Bilbo, where our hero is transformed from an ordinary Hobbit to an extraordinary hero.

Bilbo is short and chubby and enjoys his breakfast and his pipe far more than adventure. Yet, time and again, it is Bilbo who saves his companions from certain death. Gandalf recognizes Bilbo's potential early and puts him in a position to fulfill his destiny. Ultimately, it is the story of self-discovery for the hobbit.

Count me among the many fans of The Hobbit. I enjoyed the story thirty years ago when I first encountered it. And I enjoyed it again this week. It is not a complex tale, but it has been a source of delight for readers of all ages for generations.

TheReturnOfTheKingThe Return of the King concludes J.R.R. Tolkien's epic trilogy - The Lord of the Rings.

Lord of the Rings is the story of Good versus Evil; of perseverance in the face adversity; of loyalty in the face of temptation; and of friendship. They battle because they must

Frodo and Sam and Gandalf are motivated by what is right and by a chance to save their friends Sauron and his allies are motivated by a desire to rule the world. They battle because of their greed and power lust. Spoiler alert: The good guys win.

Good triumphs because the good people are motivated to protect their lands and help one another.
Sauron motivates his allies through fear and intimidation. As a result, there is no loyalty and constant infighting among his forces.

Of course, the good guys suffer infighting and doubt in the outcome, but they know their cause is just and they know they can depend on their friends and allies. And ultimately, they win because they assist one another voluntarily, despite great risks to themselves.

Return brings the 3-volume story to its climax. Gandalf, Aragorn, and the others remaining from the Fellowship of volume 1 wage war against Sauron's forces, which distracts the evil sorcerer enough to allow Frodo and Sam a chance to sneak into Mordor and destroy the powerful One Ring at the Cracks of Doom, where it was created.

One should only read The Return of the King as part of the trilogy - not only to understand how the story progressed and how we got to where we are; but to appreciate the evolution that so many of the main characters go through. Gandalf is transformed from gray to white surpassing the power of his master Saruman, who was seduced by Sauron. Merry and Pippin begin book 1 as irresponsible children and end volume 3 as heroes. They literally grow up as they both mature and gain height by drinking Ent Water; Aragorn, known only as a wandering woodsman when we first met him, claims the throne through both his heredity and his heroic actions; Frodo, of course, accomplishes his goal of carrying the ring, though it drags on his mind and his body. But it is Samwise Gamgee ("Sam"), whose loyalty and courage makes Frodo's quest happen. He came to us as a gardener and ended up saving the world, doing so with startling humility.

There are so many more characters in this book that captured my imagination: Faramir, who resisted the temptation that doomed his brother Boromir; and his father Denethor, driven mad by the loss of his son and the seeming hopelessness of the War of the Ring; and Eowyn, who disguised herself as a man to join the battle and fulfills a prophecy by defeating a great enemy.

One even finds great characters among the villains, most especially the pathetic Gollom who literally battles with himself over whether to betray Frodo and seize back the precious ring that he once owned.

I could go on and on. There are so many characters and so much texture to the world Tolkien creates, that this series bears reading multiple times. This was my second time, although my first was decades ago.

If there is any weakness of Return, it is that the story continues for so long after the war has settled. After dealing with the one ring and ending the war, the Hobbits return to the Shire to discover it has been ravaged by orcs and bad hobbits under the influence of the evil wizard Saruman.  It's an interesting story, but a bit of an anti-climax after the long quest to save the world. Still, it does show the strength gained by which our heroic hobbits, who are able to save the Shire without the help of Gandalf or the elves.

But this does not diminish the book or the series, which stands as a classic of high fantasy.  If Tolkien did not create this genre, he certainly defined it. You can see his influence in many who came after him. Terry Brooks's popular Shannara series borrows many characters and storylines from The Lord of the Rings.

Tolkien's story is epic, his writing is poetic, and his characters are memorable.

I am left with the image of Frodo expressing his affection and appreciation for the extreme loyalty shown by his friend Sam, when their demise seems almost certain:

"I'm glad to be with you, Samwise Gamgee, here at the end of all things."

And I am glad this world had Tolkien to give us the world of Middle Earth.

I began publishing this blog in January 2008 - over 10 years ago. I've been pretty consistent in adding content. I've never gone a calendar month without at least one post and I've averaged about 11 posts per month during that span. But I had never had more than 21 posts in a given month. Until June of this year. In the past 4 months, I've averaged 23.5 posts per month.

Why I write

I'm making more time to write down my thoughts these days because I see value in this. Here are some of the reasons I maintain this blog.

Understand what I'm learning

I spend a lot of time learning new technologies. I read books and articles, I attend sessions, I watch videos, and I ask questions. But the two things that solidify this knowledge are building something with the technology and explaining that technology to others. This blog helps me achieve the latter. Blogging or explaining, forces me to learn areas of the topic I might otherwise miss. I am smarter on a subject after I have blogged about it.

Share knowledge with others

I love to learn, and I love to teach. When I learn something new, I believe there is someone out there who could benefit from learning the same thing. I have received emails from people thanking me for explaining or making them aware of a technology.

Share knowledge with myself

I also use my blog to teach my future self about a technology. Often, I will work with a tool and not return to it for months or years. When I need to remember how to do something, I find it useful to have documented my experiences previously. Many times, I return to this post about how to use GitHub commands, because I don’t use these enough to remember them.

Build credibility

Technical blogging creates the perception that I know what I'm talking about. This was important when I was a consultant, as customers sometimes found me through my blog. This was important when I was seeking employment, as employers knew about my experience and my passion by reading my blog. And this is important as a public speaker, as conference organizers can see that I'm able to explain a topic on which I propose to speak.

Links

As a public speaker, I often give a high-level overview on a technical topic. Often, I will post a slide at the end of my presentation with links to relevant blog posts for those who want to dive deeper.

Practice writing

No matter your profession, effective writing is a valuable skill. But writing is a muscle that needs to be exercised. Blogging provides me an opportunity to write (hopefully) coherent paragraphs and stories. The more I do this and think about it, the better I get at it, which helps me at my day job.

What I write

I write on a variety of topics. Here are a few broad categories into which they fall

Technical overviews

Describe a given technology and why it is important

How-To instructions

These are step-by-step instructions on a technical topic, such as a programming language feature or a software tool.
Example

What I'm doing

If I have a lot of speaking coming up, I will publish a list of upcoming presentations. Of course, you can always find out my speaking schedule at http://www.davidgiard.com/Schedule.aspx.
Example

What I did

Sometimes I will experience something amazing, like a trip to Europe or South America and I'll share my impressions and experiences.
Example

Conference overviews

After attending a conference that particularly inspired me or taught me, I'll share my thoughts and learnings.

Example

Personal thoughts

Things I believe and why. Sometimes, these are very personal, such as my memories of a friend or family member who passed. Sometimes, I write about philosophical things like the importance of forgiveness. At the beginning of each month, I publish a list of all my daily gratitudes from the previous month.
Example

Career Coaching

I’ve spent much of the last few years of my career coaching others. I’ve learned some important soft skills and I use my blog as a way to share those learnings.
Example

Video

I have 2 ongoing TV shows: Technology and Friends features interviews with technologists about a variety of topics that are of interest  to other technologists. GCast features screencasts showing how to use software tools. I have been a guest host for DevRadio and other shows and I will post links to those videos on my blog.
Example

Podcasts and articles

When I'm a guest on a podcast or interviewed for an article, I link to it from my blog.
Example

Reviews

I read a lot and attend a lot of concerts and theater. I share my impressions of the art I experience.
Book review
Concert review

As you can see, my blog is both a personal and a professional one. Years ago, popular blogger Scott Hanselman gave me some advice - Have a single presence on the web. So, you can discover a lot about me - What I'm thinking, what I'm doing, and what I'm doing, and what I'm learning - here at davidgiard.com.

Thinking of writing a blog?

If you are thinking of writing a blog, I encourage you to do so. It has benefited me, and it could benefit you. Here are some things to think about as you begin.

Write about what you know and what you learn. Don't worry if it's too basic. I write many introductory posts on basic topics. If something is new to me, it's likely also new to someone else.

Don't worry if it's been said before. You may have a way of explaining that is just right for someone.

Identify your audience and your goals. Are you a technical blogger, a patron of the arts, a philosopher, a political pundit? All of the above? A targeted blog can help you focus on what your next article should be. It's worth noting that I don't actually follow this bit of advice. I post enough content that there is something for just about everyone. But it's useful advice when you are starting out and don’t yet have a lot of content.

Always check your spelling and grammar. Your blog engine will probably help with this. If it is insufficient, paste your post into Microsoft Word and press [F7] to check it. Poor spelling and sloppy grammar reflect poorly on the writer.

Find a host and a blog engine. There are many free ones out there. I use DasBlog as my engine and I host on Microsoft Azure. If I were starting today, I might choose a more popular blog engine like WordPress or Drupal.

Maintain discipline. Commit to writing at least one post a month. Set a calendar reminder. Take notes during the month that you can later assemble into a post. Infrequently updated blogs are less interesting. And abandoned blogs are depressing.

Always date your posts. This is especially true for posts about technology, because software changes very fast.

Final thoughts

I really enjoy keeping this blog. I like the fact that others have learned from what I've written, even if "others" means "future me".
