Knowledge Worth Knowing

Knowledge Worth Knowing

What knowledge is worth knowing?

The amount of information available only grows as time goes on, especially in this day and internet age. New things are created daily at an increasing rate, whether this is new videos, books, movies, social media posts, research, video games, technology, etc. Information is readily accessibly by literally anyone. 15 years ago, this was not the case, before the dotcom boom.

This information in turn breeds knowledge. Knowledge that is required in todays job market. Things are more competitive today, people are more educated, so the bar is set much higher than it used to be. The question that gets asked is “what is worth knowing”?

There’s an oppurtunity cost to everything – time learned in one field could have spent in others. This could be anything from professional development to hobbies.

This is my answer to that question, “What types of knowledge are worth knowing?”

Depth Skills

Depends what you want to achieve with that knowledge.

What I do care about is things in direct persuit of goals I wish to achieve. I like building things, so naturally I graviate towards the following:

  • web & software development
  • math
  • computer science

This isn’t to say I just learn those topics only. There are a number of other fields that do not directly correlate to those topics, but the insight you gain from it is beneficial. Things like music & music theory are a good example, which ties into math.

Whenever I think of what is “worth” knowing I like to think of the Valve New Employee Handbook. There’s a diagram called “T-shaped” people based on Team Fortress 2

Its on page 47 here. https://steamcdn-a.akamaihd.net/apps/valve/Valve_NewEmployee…

Essentially, it states a person should have a large breath of knowledge of many topics, but should have a specific depth of few related topics. Because people naturally seek others with specializations, but you need to understand other perspectives other than your own.

In this same example, my model “T” based model on the shallow side looks like thusly. Each of these shallow concepts complement the other “core” skillsets as well

Breath Skills

  • Welding & Woodworking & 3D modeling – It helps to know how to build something with your own hands, there will come a time where you will need this. It makes you realize that sometimes the best solutions are just hardware-based, you don’t need software
  • Understanding of how other industries work on a business-level, because the knowledge is applicable anywhere. I do business case studies almost everyday, industries include healthcare, nonprofit, education, restaurants, tech, startups, service-based companies, oil & gas, simulation based training, 3PL logistics, real estate, history, among many others. Knowing how other industries work gives you a wide variety of tools to work with, because many times solutions in one industry overlap with others.
  • Fixing things. I do my own plumbing and do my own car maintenance many times. It relates to software development by having you getting used to knowing how to work with other existing systems, and familiarzing yourself with technical documentation across many things include reading AWS docs etc
  • Cooking. Knowing how to cook properly highlights the importance of following directions properly before you mix up your own changes. You can’t build that amazing recipe until you’ve made the base version, and done A/B testing for flavor enhancements. You can draw analogies to software A/B testing as well
  • Art. Knowing how to draw helps you highlight the importance of sticking to one convention. Much like coding, you don’t want to change your styleguides down the road. You need to know what type of art you are making – is it building design using vanishing points, or something more freeform like a portrait design? Its all about setting requirements and executing skillfully
  • Playing Musical Instruments. Music is important in teaches you discipline. Unless you practice it everyday much like programming, you end up losing the ability to play it well. There’s other analogies to draw here as well, related to math.
  • Fighting. I did Brazilian Jiu Jitsu and Muay Thai. Its all about perspective and quick analysis when fatigued. You learn how you perform in times or stress. You learn about paralysis analysis pretty quickly here, and learn about project management practices as a result. One of my favorite quotes is from Mike Tyson, “everyone has a plan until they get punched in the mouth”
  • Video Games. I learned alot of things growing up here. What it taught me related to my main interest is how many different perspectives go in making a final product. There’s storyboarding, art, design, QA testing, programming, and much more. Software development is more or less the same, storyboarding is userstories, art is UX, design is frontend, QA is unit testing/CI, programming is backend. It might not be 1:1 but you get the point
  • TV Shows / Animes / Fiction. You can learn a lot of life lessons here as well, assuming the plotline is realistic and believable. The military actually recommends the fiction novel “Enders Game” as part of its reading list for good reasons. https://www.businessinsider.com/commandants-reading-list-201…

Pattern Recognition

There’s many more fields you can draw analogies from. You gain wisdom learning many different fields, and have a larger “catalog” of things to pull from to know what is right and what is not.

Because you see so many things you’ll just instantly know a lot of patterns. For instance, if you’ve tried hundreds of software packages, you’ll know there is always a file menu bar uptop in every app. You’ll know what the “window” pane for pane customization is usually always the 2nd to last option in many applications (adobe), and “help” is the last option here. The left pane is almost always some sort of folder tree structure pane for navigating on the larger scale. If its not its going to be a toolbar set instead.

If you learn adobe software suites, you’ll know things like affinity designer , sketch, etc are all based on the same sort of UX layout, but different. Artboards will make sense, export personas, etc. If you learn one CAD package like CATIA,SolidWorks is simple to understand. The underlying logic is the same, and you realize its just applications of linear algebra.

Learning many fields makes learning other fields easier.

When you learn many fields you recognize the most important metrics that matter. You’ll look at an item, and see many use cases that others don’t see. A good example of this is an XBOX controller. You can buy a simulation military grade controller for 1000xs that price, or an XBOX controller for military controls. You can buy shelving, or buy cheaper shelving used at restaurants that do the same thing. You can make pasta and bread using a powerdrill with specialized attachments for 10xs less whatever it cost at stores. Because it runs the same type of motor. You can use a restaurant ticket rail as a paper holder. You can fix a coffee maker with inverter issues by turning on a blender because its windings increases inductance of the circuit the kitchen applies, filtering out higher frequencies used by a cheap inverter pulled from a hackernews comment.

Instinctual Patterns

You start to see how some items can be used in multiple applications. These include things like magnets, zipties, 10 different types of tape (industrial double side sticky tape, friction, gaffer, painters, magnetic washboard, ruler, duct, scotch, packing, note-colored tape) pinederby weights, cardboard, paracord, plastic bags etc. A good example is in First Robotics (e.g. students who compete in high school robotics), metal tape measurers are commonly used as a pole extension arm due to the fact you can use actuate it with just a gear pulley and still withstand its shape. You don’t see items anymore as simply just what they are at face value, but rather by their functional properties (stick things together, store things) instead and meta data (weight, size, etc).

You start to see how some software has many types of applications. Another example is a macro app I use called phrase-express (similar to autohotkey / applescript). Its used to transcribe medical data entry correctly. But its used in so many other ways of automating, I use it to automatically write code snippets, screenshot things, text macros, etc. I use my bookmarking tool (pinboard) as a text backup of long posts I make, since it points to the right URL. I CTRL+A, CTRL+C to save documents via text-clip management tool called Ditto. I turn on captions on youtube videos all the time, so I can “speed-read” the video at 2 to 16xs playback speed, depending on content complexity and what I hope to get out of it.

You also realize that sometimes people use a piece of software for many unintended uses. In videogames, sometimes these bugs become features super smash bros & iframes, street-fighter and block cancellation, speedrunning. Another good example is the omnibar on the browser, that was not its intended use for using it as a google search. People will find to make things work for them as best they can. People will make full blown SaaS solutions with just excel, since that’s all they know how to use.

You also realize the power of good formatting and storytelling. Mostly from reading too much terrible fiction from terrible authors, but occasionally finding some authors who make masterpieces. You take those ideas, and bring it to your own writing.

You start to realize who is and who is not worth following as well. You start to see who shares the same mindset as you, even if you’ve never met them. This could be tiny bits of metadata on someones github repo, all the way to just what they put on their blog. Many companies naturally use this as part of their cultural fit and hiring processes.

Novel Ideas

As a result you are able to string together a bunch of off the shelf solutions to a unique problem. Or cross-pollinate novel ideas if no solution suffices. Sometimes these ideas become plugins and extensions that many users use, othertimes it becomes a business that no one else has thought of that you end up doing instead. Because you already are familiar with so many things, you don’t need to do any as much research as you used too. Competition is validation. You can filter out what is garbage advice and what is not. You’ve seen what works & what does not, its pure instinct now. You rely on your own set of experiences across many fields to make the assessments for you. You can instantly crowd source solutions to ideas on reddit, youtube, amazon etc, without ever asking anything, because its all there already. You learn when reinventing the wheel is a good thing and when its a bad thing.

Learning different fields is one of the fastest way to gain wisdom and experience to make better informed decisions
