  • printing

    Ten years ago I heard about 3D printing and thought it was crazy and for people with tons of money. Four years ago I found out my neighbor had a printer and thought, “oh, wow…I could never do that.” Seven months ago I was taught how to use a 3D printer at work. Three months ago I put together a Prusa Mark IV with a coworker. So I’ve been borrowing the printer to learn about using the slicer, when to use supports and brims, and print desktop organizers or tongs for my kitchen when I’m not printing airplane parts.

  • Eating is hard

    Losing weight is probably less important for regular people than you think. Increasing muscle mass is more important than focusing on body fat percentage.

    There was an article in the Washington Post last fall sort of downplaying low-carbohydrate diets. Maybe she’s right.

    If so, why does one eat less on fewer carbs?

    A hypothesis is because of fewer and lower insulin spikes, resulting in less feelings of hunger. See more at Pubmed on how Ghrelin and leptin regulate hunger.

    Another hypothesis is that by eating fewer carbs you eat either more protein and/or more fat, both of which are more satiating than carbs.

    If so again, in the studies where people lost weight, did they just lose fat? Or did they lose muscle and fat? I’d rather be a bit overweight but muscled and strong than lean and weak and small muscled.

    She also said “After a year, any low-carb advantage all but disappears.” This isn’t an indictment of a low carb diet, but rather could point to multiple mechanisms. Has the body reached a new set-point and the ghrelin and leptin values different?

    Too many people conflate “losing weight” with health.

    A person can be low weight, but also low muscle and a person can be obese and have a high muscle mass (still not necessarily healthy). The older we get the more at risk we are for sarcopenia.

    Regardless of her argument, you can start with what should we eat at all, from a macronutrient perspective.

    We all need protein (essential amino acids) and fat (essential fatty acids).

    There is no such thing as essential carbohydrates. Maybe I’m wrong.

    We also need micronutrients (Vitamin C, Vitamin A, etc.), which can be found in protein, fat, or carbs.

    If you start with protein, there are two considerations: grams of protein per body weight and grams of protein per meal.

    Protein per body weight estimations run from .8g/lean body mass all the way up to 1.0 grams per total body weight. Some researchers recommend a minimum of 30 grams of protein per meal to ensure you get enough leucine to trigger protein synthesis. Dr. Gabrielle Lyon is one advocate of this approach.

    To help determine how many grams of fat and carbs you should get, you would need to estimate how many calories you should be eating.

    There are calculators online to estimate your basal metabolic rate (BMR) which estimates how many calories you expend based on your age, height, weight, and your body fat percent. The BMR is adjusted based on your activity level.

    Another consideration is your Total Energy Expenditure (TEE), which is how much you might have burned off in a day based on activity level.

    Fat and carbs can then be tailored based on your meal desires to meet your caloric needs.

    A concern but not an indictment: some of this author’s other articles focus on the goodness of vegetables and how pork products are bad for the environment.

    It bears further investigating if she is a vegetarian and/or doesn’t understand the benefits that ruminants (I know pigs aren’t ruminants) play on soil health.

    Summary

    I don’t necessarily advocate or strive for a low carbohydrate diet.

    Looking at my cronometer app on my phone, I’ve averaged 50 grams of carbs a day for the last two years or so.

    I do strive personally for a low grain diet, and get my carbs primarily from veggies (broccoli, asparagus, green beans, cauliflower, lettuce, etc.) and fruits (berries, bananas, apples, pomegranates, watermelon).

    The quality of food is important, so when deciding whether to eat a slice of bread, you would ideally not just say “should I eat 22 grams of carbs right now?” but rather think about the larger value to your overall diet.

    I may have grossly oversimplified the details of the above, but I’ve been ruminating on this for a while.

  • Automate

    Microsoft’s Power Automate is a great tool to connect SharePoint Lists, Outlook, Forms, and other apps to keep data consistent, standardized, and repeatable.

    I’ve been using Power Automate for a few years now to help my coworkers get out of their Outlook inbox or PowerPoint slides as a starting point for work. Granted, much of the Flows I’ve built are automated emails, but it’s a start.

    One Flow I built connects a questionnaire in Microsoft Forms to a Planner, essentially turning a multiple page Word document into a form and then a set of action steps for specific teams. Much more useful than sending around a word document through email. This took a few days of coding to get the right dynamic content correct.

    My latest project creates a custom email by creating three HTML tables from a SharePoint List with three filters. This is essentially creating a weekly email to remind coworkers of upcoming meetings and tasks to review, without giving them access to the full list and having one source of data for staff officer reviews and the custom email. This took weeks of coding and several failed attempts, so don’t be discouraged if your own Flow doesn’t work on the first try. Remember to convert from UTC.

  • Lost in Ubuntu

    If you have an old laptop, one way to still make it useful is to install Linux. And if you use Windows now, you’ll probably want to install Ubuntu.

    We have an old HP laptop and I installed Ubuntu on it in November. Then we left the laptop sit…and we forgot the password. Two ways to recover the password:

    • GRUB (Grand Unified Bootloader) recovery
    • use a live USB and open a terminal to change the password

    Now, write down that password!

  • Blogging

    Should you blog? Should you post? Should you like?

    I am a big fan of Professor Cal Newport’s ideas about work and how to use technology properly. He has never had a social media account, but rather has how own website, https://www.calnewport.com/. Rather than limiting himself to Twitter’s 140 characters or posting something jejune on your Facebook wall, he owns his content.

    The other point he makes is that by limiting or eliminating your time spent on social media platforms, you take yourself out of the hyperactive hivemind that most of us get sucked into. Rather than idly scrolling through everyone’s Facebook wall or responses to a Twitter feed, by blogging on your own site you can ignore comments (or turn that function off) and read one post or page at a time.

    Rather than using email as a general purpose communication system for every time of message you could send or receive, have custom designed email addresses for the projects you run. I used to have a Gmail address that was firstnamelastname@gmail.com, but have switched to Protonmail addresses with specific addresses for blogging, Scouts, online purchases, etc.

    As to the prospect of limiting your time on social media, you might be thinking: I will miss out on my favorite uncle’s cat pictures or I need to stay abreast of the current news articles. First ask yourself what you gain by using Facebook, Twitter, Discord, or any other new social app. How much time do you spend on the site consuming other’s ideas or images? If you originally joined a specific site for a club or group, pare down your use of the site so that it only serves the function for how you communicate with the club. As an example, you could check Facebook messages on Saturday mornings while you drink coffee, while minimizing the extra information scrolling by.

    For a deeper approach, try a digital detox for 30 days. Essentially, remove all the apps from your phone that are optional. If you need an app or function for work or family, don’t remove it. You’ll also define use policies for how you use your phone, computer, or whatever devices you use. Don’t use your phone when you are bored. Very importantly: find a real world hobby to take up your free time. Create something. You will probably learn something about yourself.

  • Still Teleworking

    If you are reading this, then it’s been 22 months since I first started teleworking. If you would have asked me in early 2020 if I would like to work from home, I would have said, “Sure, why not? Sounds nice. What, me worry?

    After having worked from home for the majority of the last two years, here are some observations I’ve made about my own behavior.

    Here’s what works:

    • A morning workout before checking email leads to a better day.
    • Get a hot shower after the workout, preferably before lunchtime.
    • Read a few pages of a nonfiction book.
    • Coffee…at least two cups before 0830.
    • Whey protein smoothie, about an hour after my workout. I like Jocko Gorilla Vanilla with some collagen and grass-fed milk.
    • Take a mid-afternoon walk around my neighborhood, preferably with my wife so we can discuss how well The Wheel of Time series matches the books. (Spoiler alert: it doesn’t).
    • Quit work by a reasonable hour, normally by 5pm.
    • Plan the next day in advance, with time-blocks and the big tasks you want to accomplish.
    • Go to bed by 10:30pm

    So if you are still teleworking the majority of your work week, consider these three ideas to keep yourself sane:

    • Focus on projects, not email
    • Take breaks to get out of your chair
    • Do less, but do it better.
  • Mastery

    When I was younger, one of my favorite websites to waste time on was Lifehacker’s “This is How I Work.” Even now, searching for that link, I am starting to get sidetracked looking at all the great authors and what type of laptop they use. I am pulled by the notion of, “if I just try this new notebook, or this new productivity system, then I will be productive, or creative, or have a new insight.” I wish this were to be true, but I can still accomplish things with my cheap five year old HP laptop and a $20 notebook.

    Unfortunately, I find failure more instructive then success. Failures can be a turning point in our lives to improve ourselves and how we act. In 2015, I fell and broke my right knee. This was challenging in many ways, but mostly because I had to rely on others for almost three months. I couldn’t drive, dress, or shower without help. Looking back, this was an opportunity for me to relearn how to lift weights. I read Starting Strength, fixed my squat, bench, and deadlift form, and am stronger today than I was six years ago. I have been focusing on my strength training process and programming, focusing on simplicity and ignoring complex exercises or “confusing my muscles.”

    In Ryan Holiday’s book, Ego is the Enemy, there is an early chapter titled, “Become A Student.” He describes Kirk Hammett’s acceptance into the band Metallica and Hammett’s continual practice of being a student, learning what he didn’t know about being a guitarist, to stay relevant and stay humble. The chapter continues into martial arts, describing how being a student allows you to subsume yourself, and how “false ideas about yourself destroy you.” You must subsume yourself and face reality by destroying any illusions you have about yourself. In jiu-jitsu, egos don’t last long on the mat. Either you quickly learn how little you know or you leave. Even those who do know a lot, eventually know how much they don’t know. Holiday references Frank Shamrock who had a system he called plus, minus, and equal. I’ve also heard this described as “mentor/peer/student.” This means that you have someone more experienced than you who you can turn to for help, peers who you can train with, and at least one student or younger person you are helping train or grow. Very importantly, the act of being a student keeps you humble. You can’t have too big of an ego if you admit to yourself that you need to keep learning.

    Holiday also describes how the subsummation of your ego negates the likelihood of “Eureka moments.” If you are waiting for inspiration to strike, you won’t do the work necessary for your trade, your craft, your art, whatever that is. So rather than sitting down to write everyday, you’ll browse the web waiting for inspiration. Rather than training every day, you’ll browse Muscle & Fitness for new workouts. Rather than trying to learn how to make an omelet, you’ll watch Food Network and…well I don’t know since I don’t watch Food Network. Holiday states how, “To become waht we ultimately hope to become often takes long periods of obscurity, of sitting and wrestling with some topic or paradox.” I recently found this Zen koan about the master swordsman. At first the swordsman thought he was great, but it wasn’t until he had trained for over three decades that he became a master.

    In his book Flow, Mihaly Csikszentmihali argues for deeper, focuses pursuits leading to a deeper, richer life filled with purpose, contentment, and happiness. He introduces the book by describing how he “discovered” that “happiness is not something that happens…It does not depend on outside events, but rather, on how we interpret them.” I could have been angry at the world, angry at the hard ground, angry at myself when my knee fractured in an inverted V. None of that would have changed the reality. Mihaly describes how optimal experiences can be achieved when we feel in control and have some input into our fate, “that contrary to what we often believe or are told, the best moments in our lives, are not the passive, receptive relaxing times…the best moments usually occur when a person’s body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile.” As a corollary to this, later in the book he points out that, “To become enjoyable, a relationship must become more complex.”

    To tie these notions together, to achieve happiness you must strive for difficult and worthwhile endeavors, acknowledge what you don’t know, seek help from others, and continue to learn and add complexity to your lives. Happiness does not come from going to the beach or binge watching Netflix. Seek the process of continual improvement mastery, rather than the end goal of being “happy.”

  • The Archer’s Paradox

    The archery club in Washington, D.C. meets Saturdays at a park in Derwood, Maryland. I used to think I was a good archer until I met up with the club before Christmas 2021. I have been shooting arrows since I was in elementary school, but haven’t really started to study the craft of archery until I attended a Father and Son camp at Turtle Island in Boone, North Carolina. They had a round-robin activities session and archery was part of it. The archery instructor had a set of bows that he had made and introduced me to bowyering, the art of making your own bows. He recommended The Traditional Bowyer’s Bible series, explained the archer’s paradox, and told me about other intricacies of the sport I had not heard of. The archer’s paradox, as I understand it, describes how an arrow shouldn’t be able to hit the aimed for target, as it’s original trajectory is at angle to the actual target, but its spring in the arrow shaft recoils the velocity vector to the target.

    When I was a kid, we set up a hay bale in my backyard and would shoot at it with the fiberglass recurve bow we had from a short distance away. I remember my dad telling me what recurve meant, but can’t recall any other set of instructions for form, technique, breathing, back squeeze or anything else. This field was also our BB gun range, baseball field, garden, pine tree nursery, hide-and-seek arena, fantasy world, and held other portals to unknown universes.

    I have also been shooting at the Scouting events my sons have attended the last four years and thought I was pretty decent. I can hit the bullseye some of the times from 10 yards, but wasn’t consistent or knowledgeable about the what and why. I finally bought two youth compound bows and a takedown recurve at Dick’s last summer after years of debating if it was worth it to spend the money.

    I found a local indoor archery range in Gaithersburg at the Invicta fencing club. This location is convenient, but the instructors are focused on the fundamentals of archery, not necessarily advanced techniques or equipment, such as anything beyond a 25 pound recurve bow.

    This past summer I passed the online and in-person courses to earn my USA Archery Level 1 instructor certification. I hoped to be able to lead a basic session for youth wanting to learn how to shoot. Much of the instructor materials focus on lesson plans for teaching young people about the sport of archery, for competition and balanced against other sports and school.

    After over a year of forgetting about it, I found the Lake Needwood archery club. When I first moved to DC, I found the club’s website, sent a message to the information email address, but never heard back. So when I had my own equipment I went there on my own a few times. A week before Christmas I took one of my sons to the park and found the club there. The members are very knowledgeable, friendly, and welcoming. There are archers who focus on recurve, compound, traditional Asian archery, and one member who made his own crossbow from a kit. Some equipment is for sharing for new members, both to use during the afternoons and to see how you like a certain bow before buying your own.

    So now I have a crossbow, a Genesis Gen-X compound bow, a recurve riser, a Bear Cub longbow, and two youth compound bows, along with a score of other safety and accessory gear. And I know so little about archery.

  • Hello world…again

    This is my first post on my new hosting platform. I tried to clean up some pages on my site and found out that my former platform, www.wordpress.com, has several limitations it places on its bloggers. So I transferred my hosting to A2. Short version: if you want full control over your site, host it yourself. Rather than hosting it on WordPress dot com. You’ll likely work harder but pay less.

    So this week I’ve been remapping the domain name server (DNS) hosting and the mailbox routing in my host’s DNS records. I know, I know, it sounds much more fun than it is.

    It is like anything else: if you want to fully own your creative process, you can do that, but with the cost of learning more about what you are doing and the esoteric details of managing your craft.

    If you are wanting to disconnect from platforms that own your data, start your own blog. Own your narrative and your content.
