- From the Introduction: "Each satellite may carry traffic for dozens of independent networks through an array of on-board transponders, each covering a diameter of thousands of kilometers (at most a third of Earth’s surface)".
Can someone help me understand the use of "diameter" in this sentence. I am guessing it refers to the satellite's signal coverage of the Earth's surface. If that's the case, wouldn't something like arc degrees be a better measure? I just can't figure out how "diameter" can be used to describe a coverage arc or area.
- "Unbreakable: The Western States 100" [1] came to mind after you reminded me of the Barkley documentary. “The Barkley Marathons, the race that eats it’s young” seems more human and better grounded than "Unbreakable", but "Unbreakable" captured the excitement of running ultra marathons so completely for me.
- What's the method for connecting the watch to the Internet?
Garmin Bounce [0] has some of the features on your list and many more (like on-watch LTE). I don't believe it includes the ability to use heart rate and stress levels to trigger automatic alerts. I have no first-hand knowledge in this field, but I would imagine it would be very difficult to implement this without many false positives especially for kids in the day care and school settings because excitement and play likely look very similar to anxiety and distress from the point of view of the heart rate sensor.
- The author says that they tend to load all of the assets on init. This sidesteps the issue of the C#'s garbage collector (GC). I am not a C# developer, but seem to recall reading that GC can cause unexpected slow downs. Web search shows articles on tips and tricks for optimizing GC in C#, so it seems like a real issue.
Does anyone have any first hand experience they would like to share? Is it easy to avoid the GC slowing down your game unexpectedly? Is it only a problem for a certain class of games?
- I am not at all familiar with C# development, but the author mentions Native-AOT, which, from a cursory look, seems like a C# compiler.

- No BIOS necessary when we're talking about bare metal systems. printf() will just resolve to a low-level UART-based routine that writes to a FIFO to be played out to the UART when it's not busy. Hell, I've seen systems that forego the FIFO and just write to the UART blocking while writing.
- Tangential to this... Wright brothers lived and worked in Ohio, but the first flight happened in North Carolina due to its wind conditions and soft sand. In the early 2000's (if I remember right) North Carolina came out with a license plate with the image of the Wright Flyer and a slogan of "First in Flight". Ohio then came out with a license plate with "Birthplace of Aviation". A bit more on this here: https://en.wikipedia.org/wiki/Wright_brothers#State_rivalry
- That's what Content Authenticity Initiative (CAI) is trying to accomplish.
- PyTorch

- The basketball thing can be such a shit show. As a parent of a kid that fell in love with basketball, did travel AAU basketball and ended up playing for a D3 college, I've experienced parents at all levels showing their full ass.
Examples... Their coach at a rec league for 9 year olds was assaulted by the opposing team's coach at the end of the game. I've seen the cops being called to protect the refs and parents being escorted out of the game after threatening the refs. It goes on and on.
All that's to say that the steaks don't seem to matter. Folks are passionate in a disproportionate way when their children are involved.
- Starlink to T-Mobile is using PCS spectrum (1850 – 1990 MHz) licensed to T-Mobile to provide Directo-to-Cell (DTC) service, not whole 5G spectrum.
- To add to what others have posted... Activity (i.e. running, walking, cycling, etc.) FIT files are found in the GARMIN/Activity directory on the watch after connecting it to a computer over USB. File names are date time stamps.
- Look into driving apps designed to track miles driven by learners who are working towards their full driver's license. My state's DMV requires a driving log with start/stop times and miles when getting the full license from a provisional learner's permit. I think my kids used RoadReady [0]. It can email a log, but I don't know the format.

- The book has been on my shelf for a long while, and I haven't read it yet, but I really like the full title "Mistakes Were Made, but Not by Me: Why We Justify Foolish Beliefs, Bad Decisions, and Hurtful Acts"
- That's my favorite book as well. I came to it much later than college, and still found so much wisdom in it.
- Garmin has rolled out a sleep mode feature that makes the AMOLED watch face sparsely populated, and you can set the brightness to the lowest setting for sleep mode.
Compared to my watch set to the lowest sleep mode brightness, the brightness in this image is not set to the lowest level (probably for the purposes of showing the sleep mode watch face features), but this gives you some idea:

- They probably mean "on-board" instead of "on-chip".
Data sheet [0] section "5.4 Powerchain" shows an external RT6150 buck-boost switcher with an external inductor.

Edit: reading further in that section of the data sheet, "The RP2350 has an on-chip switching regulator that powers the digital core at 1.1V (nominal) from the 3.3V supply, which is not shown in Figure 7."
It has proven difficult enough to find a PDF of the schematic (I don't have Cadence Allegro installed) that I am giving up.
- When I think of "sport" I think of "fitness" watches from Garmin and Apple Watch. Patek sport watch is definitely not that. What is meant by "sport" in case of the Patek sport watch?
- This is probably not helpful, but, can you figure out the infra of https://godbolt.org/ and follow what they have done?
- Matt Parker ("Stand up Maths" channel on YouTube) gave a very informative and entertaining lecture in 2010 titled "Clutching at Random Straws" [0], which, among other things, covered something similar. From the subtitle of the video: "Did aliens help prehistoric Britons find the ancient Woolworths civilisation?" The answer is "no". Given enough data points, you can find all sorts of patterns.
- Ze Frank (True Facts YouTube Channel) recently released a video about crows crafting tools to solve problems. It's quite amazing and, of course, very funny: https://www.youtube.com/watch?v=B-HF-wBwQsc
- Your "my life in weeks" page is just lovely. I teared up from the tenderness of it.
That is such a great idea. I have been toying with the idea of writing a memoir, but I haven't started because it seems so daunting of a task. This, on the other hand, is constrained, but still leaves a lot of room for creativity.
- 100 Mbps Ethernet over barbed wire was demonstrated back in 1995. [0]
"Only four properties really affect the performance of most digital transmission structures. The "big four" transmission-line properties are impedance, delay, high-frequency loss, and crosstalk." Dr Johnson then goes to describe these properties in barbed wire.

P.S. Yes, this is the Dr. Howard Johnson of the famed "High-Speed Digital Design" book.
- You may also enjoy a modern-ish take on this from Zoro's Field: My Life in the Appalachian Woods.
- $185/ton of CO2 emitted is what the study estimates to be the actual economic impact of emitting a ton of CO2, right? The current price of carbon futures is $68.80 [0].
Edit to add: That $185 is in 2020 USD, which is $223.26 in current USD. [1]
- Is this a coffee table photography book or does it teach you anything behind what's in the images?
- This is fascinating. Can someone recommend a book that goes into similar depth as this article covering these types of symbiotic relationships? Examples I can think of are:
- Organelles evolving from other living organisms as described in this article - Bacteria in and on our bodies - Fungal mycelium in relation to plants
I am sure there are many more.
Another thing I do that works well for me is just counting breaths. On the breath in I think "in-n-n-n-n" and on the breath out I count. When I lose count, and I am still awake, I start again from 0, as any sane programmer would ;-).
ETA: For a couple of months I have been doing a short gratitude routine as I am getting into bed. I acknowledge the good and positive things that happened during the day, and I tell myself that I did a good job (if I did) or that I did as well as I could today and that's good enough for today. Then I think, "And now it's time for rest. I've been looking forward to this." If any part of me starts thinking about the day again or thinks about tomorrow, I gently reassure it that I will attend to all of this tomorrow morning and that now it's quiet time and time to rest.
All of this plus 250 mg of magnesium an hour before bed has made falling asleep super consistent and easy.
