  • Recommendations For Distracted Free Writing

    August 25, 2024

    +

    +

    Wired recently published their recommendations in an article entitled "The Best Apps for Distraction-Free Writing: Focus on your words and not on your toolbars with these eight minimal writing apps for your computer, your tablet, and even your phone.".

    I use two of those recommendations:

    1. Obsidian (only application open, one tab open using the plugin
    2. Google Docs (full-screen mode, only one document open)

    Other best practices: turn off all notifications and close all the other applications on your computer or tablet.

    These suggestions work well for Chromebooks, PCs, and Apple iPads.

    I am a big fan of Cal Newport's Deep Life podcast.

    One of his monthly goals is to read at least five books, which he then covers in his podcast.

    Fellow podcast fan Bram Adams (bram@bramadams.dev) has created a database of all Cal has read here: Cal’s Five Books of the Month.

    Bram's site also makes fantastic use of Notion.

    Thanks, Bram!!

  • Podcast Series Recommendation >> Agent of Betrayal: The Double Life of Robert Hanssen

    I recently enjoyed the podcast series Agent of Betrayal: The Double Life of Robert Hanssen.

    It was well-produced, researched, and sourced.

    Although I thought I knew a great deal about Robert Hanssen (Wikipedia), this podcast provided a bunch of new information I was unaware of.

    You can listen via:

    • Apple iTunes
    • Amazon

    I also recommend these podcasts from the International Spy Museum in Washington, DC:

    • “America's Most Damaging Russian Spy, FBI Agent Robert Hanssen" – with Lis Wiehl
    • "FBI Counterintelligence and the Robert Hanssen Spy Case"
    • "SpyCast Ep. 610 | Agent of Betrayal, FBI Spy Robert Hanssen with CBS’ Major Garrett and Friends"

  • My 2024 Daily Morning Personal Devotion Plan

    Here is an update to my 2023 plan.

    This year, I am reading and journaling about the following two books as part of my daily morning routine:

    • “Truth For Life: 365 Daily Devotions” by Alistar Begg
    • “The Daily Stoic: 366 Meditations on Wisdom, Perseverance, and the Art of Living by Ryan Holiday &  Stephen Hanselman

    I was wondering if I was going to do The Daily Stoic book again, as I’ve re-read it for the last four years. However, after the first week, it is just so good that I’m happy to be re-reading it.

    As far as last year’s two other books:

    • “Quiet Times with God Devotional: 365 Daily Inspirations” by Joyce Meyer
    • “The Vagabond’s Way: 366 Meditations on Wanderlust, Discovery, and the Art of Travel” by Rolf Potts

    I enjoyed both of them very much, and I recommend them if you are looking for something to do as part of your daily routine.

    I am reading these books on my Kindle Paperwhite (which I also recommend if you want a dedicated ebook reader).

  • 2024 Continuous Year Calendar PDFs For Free Download

    January 5, 2024

    +

    +

    +

    +

    +

    +

    Just like last year, I have created some downloadable PDF files of "continuous" calendars for 2024:

    • Vertical version (PDF)
    • Horizontal version (PDF)

    I hopefully did the conversion from 2023 to 2024 correctly. It was especially tricky since 2024 is a Leap Year. If you find an error, then please let me know.

    These were inspired by Kairos Cognition very elegant calendar:

    Karos

    This is what the Horizontal PDF looks like (3 copies if you print one):

    Continuous 2024 Calendar (Horizontal)And this is what the Vertical PDF looks like:

  • Walking Tour Fort Rosecrans National Cemetery – Part 1 of 4

    +

    +

    +

    This walking tour of Fort Rosecrans National Cemetery was filmed on Monday, December 18, 2023.

    The cemetery is in the Point Loma area of San Diego, California, near the Cabrillo National Monument.

    The area walked was in the Northern-Eastern section (Part 1).

    There are three more sections that I plan to walk in 2024.
