Today, I watched the Lone Survivor with two friends and was once again reminded of the brevity of life, the importance of principle and the value of friendship. I found the movie to be a masterful combination of plot, emphasis and character development. It is tough to capture the breadth emotions present in Marcus Luttrell’s detailed book in two hours, but the movie does capture the heartbreak, the passion, the sacrifice of modern warfare — all juxtaposed with the rapid transition from the safety, comfort and contentedness of modern forward bases. Further contrast comes from American optimism (“Good things happen to good people, right?”) with middle-eastern determinism, but nothing hits you harder than the fierce determination of the seals contrasted with our comfortable armchair warrior lives.
If you want to get WordPress to accept automatic updates and are running your own server, you want the flexibility to not go through these steps every time an update arrives. You also want good security. I had to do this recently on several sites and thought I would share my notes.
My previous post on TelexFree was the result of a quick spreadsheet model that assumed a geometric growth rate that was uniformly assumed for all members. On a recent flight, I built an object oriented model in MATLAB to more realistically show how telex works. This is a really fascinating system.
Ever wonder why fund managers can’t beat the S&P 500? ‘Cause they’re sheep — and the sheep get slaughtered. I been in the business since ’69. Most of these high paid MBAs from Harvard never make it. You need a system, discipline, good people, no deal junkies, no toreadores, the deal flow burns most people out by 35. Give me PSHs — poor, smart and hungry. And no feelings. You don’t win ’em all, you don’t love ’em all, you keep on fighting . . . and if you need a friend, get a dog . . . it’s trench warfare out there sport and in here too. — Gordon Gecko
I built a much better model with more realistic constraints available here
Outside of generating new information or product, risk, diversity and time horizon are only variables I’m convinced an investor can control. This means invest broadly over long time horizons and keep taxes and expenses low. If you want outsized returns, you must take on more risk or make something people want to buy. Most wealth is created by businesses making real products, but wealth can still accumulate from appreciating assets (real estate, land, gold, internet domain names, etc). However, both these methods take a lot of time and effort. Can you make a lot more quickly through selling VOIP services, posting internet ads and joining a Brazilian-focused multi-level marketing (MLM) club called TelexFree?
As we enter the Christmas/holiday season, I’m asking lots of friends how they are doing and how their year has been. Almost everyone says “it’s busy”. This takes many forms, from “crazy busy” to “absolutely busy” or “scary busy”. Since words often lose their meaning, I’ve thought about a scale we could use to better convey the level of busyness in our lives. I think the best way to delineate levels is by the loss of freedom that occurs at each inflection point.
I’ve always been intrigued by the story of the Harvard applicant who penned a three word answer to an essay prompt of “what is courage?” The myth has that he was accepted. I like the story because it highlights the risk and reward trade that we calculate in all our decisions.
When I work with WordPress, I am still a ruby coder in a PHP environment. I spent several years doing PHP only and have watched the language develop nicely, but still like to focus on Concept/Design, CSS3, Ruby and JavaScript when I’m doing web development work. In the hope that someone might benefit from my workflow, I’m sharing my basic setup.
One of the most undervalued skills is the ability to set a routine and stick to it.
Modern workflow is constantly inundated by distractions which can knock us off our game. I know a lot has been written about email, how to shut it off and keep tasks and priorities aligned, but phone calls, and the raw ability to go down any rabbit hole you want to is incredibly dangerous to both getting things done and enjoying life.
Even as I tried to write the content above, I was distracted to send out an email, update my books read on shelfari and start building gift lists for Christmas. I also opened four tabs that I want to look at when I’m done with this post.
I’ve started to get much more serious about WordPress themes. For me that means making them from scratch instead of modifying someone else’s theme. Traditionally, I just purchased a template and modified it. Now I’m starting to work with good designers and working from scratch.
I love to exercise. It gives me an excellent chance to relax and preserve my overall goal of maximizing my physical strategic margin, or keeping maximum function as long as I can. (I want to be able to wrestle with my grandkids as long as I can.)
I also love data. I love to track everything and know that if I care about changing something I should probably track it. I am also becoming more aware of a tendency to focus on long term goals instead of achieving short-term success and moving on from there. For several years, I have recorded if I worked out our not and give myself a 1-5 score for the category fitness. (As I do for my wife, relationships in general, devotional living and stress.)
While I have enjoyed looking back at my monthly graphs and reports, there have been several trends I’ve noticed that have been very insightful for me. I also am motivated to meet my goals when I know I am accountable to myself and anyone (my grandkids again?) who are going to look at my data. However, one of the things I have never been able to crack is how to track my workouts. I thought about making a simple text field that I can search, but how could I see my progress over time. When I was primarily a runner, I used to make graphs showing my mileage and overall pace improvements, but how could I show improvement with the diversity of workouts that CrossFit is providing me.
When I had to list my goals, I went back to my values. In this case they are:
Don’t get hurt (learned this one from experience)
Frequency: workout every day in some way if possible (yes, diversify)
Diversity: don’t long-neglect any of the core principles: Strength, Stamina, Cardiovascular Endurance, Flexibility, Speed, Power, Agility, Accuracy, Balance and Coordination
Improvement: improve in all core principles
With this in mind. I would like to track workout’s at the most granular level, if I could do so quickly. So, in setting software requirements, I look at the questions I would want to answer. Some examples where (T) is a threshold (must do) and (O) is an objective (want to do):
(T) Have I worked out frequently this month? (=> calendar view over varying times)
(T) Am I improving? (=> need to show incremental progress; chart)
(T) What is my PR for overhead squat? (=> query that lists PRs for all workouts; make this public?)
(T) What is my last score for “Cindy”:http://www.whatiscrossfitexercise.com/wod-cindy.php? (=> that would be on PR page, so named workouts and movements would have to be in a similar query)
(T) What are my last 10 scores for Cindy (=> time series query from previous)
(O) How many Watts did I burn this week? (=> need to track Work / Time)
(O) Is my ability to do more work faster improving? (=> need to index performance)
Next, I wanted to look at the data format when I just write down my exercises:
Run 3.65 miles in 20 minutes (=> need to record, distance, time and workout name)
Cindy: 28 rounds (=> need a database of crossfit workouts preloaded)
5 rounds Cindy, 15 Squad Cleans (#145), 5 rounds Cindy in 13:48 (=> need to record reps of named workouts)
Bench 245 x 10 x 3 (=> need to record reps, weight, rounds | might not have time)
Bike 6 miles in 25 minutes (=> same requirements as running)
Climbing for 2 hours (V4+!) (=> need notes field; might not have distance or reps)
All together, I had enough to start on the database design, which I always do on paper and ended up looking like this:
In listing out the basic data, I clearly needed to track weight and distance, in addition to the time duration and quantity that the basic exercise was performed. In order to connect between a workout and a specific instance of an exercise I created a join table value named an exertion. The tricky part would be the set of characteristics required to derive power from each movement. For example, the bench press would move a distance of my arm down and up with a resistance equal to the weight on the bar. My agile strategy was to input the data and start recording what I could and then figure out how to deal with the data later when collected.
The results of my initial web application are below:
Some features I did incorporate were the ability to create an exercise on the fly when inserting data. I wanted to make the data input quick and painless. I also made the four input fields very basic, and not tailored to the exercise in question. A future iteration on this would be to disable fields that are not relevant to a particular exercise. Through using the chronic gym and rails virtual attributes, I made the input general as well, so you could type in 6:41 for a mile run time or something like 6 min and 41 seconds or even 401 seconds. I haven’t incorporated it yet, but I also would like to input the distance in meters or miles and have either one work seamlessly. In any case, this format is going to work for now. I plan to collect data for a couple months, then play with adding the ability to track progress and some basic validation on the form elements. Please let me know if you have any comments or suggestions how I can make this better. This might already exist, but I haven’t found it, and I want to get this to work with my overall system and will probably stick to a custom solution, so I can own my data and adapt the system over time.
