> I'm not smart enough to intuit NAND from transistors. I'm also not sure I will be alone in that. It's such a weird difficulty wall.
I agree with you, because I feel like I only got that one because I happened to get curious about CMOS (PMOS + NMOS) logic earlier this year, and remembered the general idea from before. Otherwise, I don't think I would have figured that out either. Google image search for CMOS NAND basically shows the solution, but the game doesn't tell you that's what it is until after you beat the level. I think seeing the answer, then immediate trying to reproduce it from memory is a good way to learn. Then if you try again the next day/week/month and are still able to remember it, then you've learned it.
I also looked up a solution for the full adder since I couldn't quite remember how it worked.
Tangentially, I've gone through similar material over time repeatedly in the games nandgame and Turing Complete, going through the Nand 2 Tetris course (on Coursera), building Ben Eater's breadboard 8-bit computer, reading "Code" by Charles Petzold and "The Pattern on the Stone" by Danny Hillis and "Digital Computer Electronics" by Malvino since that was what Ben Eater partly based his computer design on, and going over digital logic in CS-related EE courses up through how a CPU is made. But most of those barely cover anything below the logic gate level and I don't think any of them covered CMOS/NMOS/PMOS specifically which is why I got curious about them this year.
It's pretty fun though (my type of fun anyway), and I'm really curious to see how the rest of it goes since it's building a GPU instead of a CPU for a change.
They had the longest reaction shot of some people filming it with their phones (maybe they got a good shot) and when they switched back to after the booster separation I said at the time, “that would have been cool to see.”
Yeah it was horrible. Why are we here, to watch a video feed of other people watching it live through their phones?
We have 30 seconds maybe while this thing is in the local atmosphere, Jesus Christ just keep the camera on it and let us watch it launch.
I know this sounds like whining, and part of me is annoyed that I'm so annoyed at this. But it was just such an emotional moment, and it felt like the media team had no plan or any idea what to do.
Amazing seeing this here. I hung out with him a few times back then, and I was just thinking about this again just a few days ago. It was really great spending some time with such a smart person. He showed me how he would write little notes and mind maps in the margins of books, and the peg system of mnemonics. One of the times I was there, he was teaching python lessons to someone. I tried to make sense of his notebook system, and to this day I still use color coding, and things like a triangle for pieces of data in my notes. Somewhere, I have or had a copy of this with a lot of writing in the margins trying to make some linear sense of it.
Lately, I've been keeping an "engineering" notebook, using similar technique to the original poster's technique: dated entries and a place for a table of contents (that I need to update).
Hover over the green button in the top left of the window. I recently found out about that menu for moving a window between screens, which is also an option it has. (I also just found them in the Window menu if you prefer that. I dont; the options take an extra level of hovering to get to.)
You can also long-click the button instead of hovering. Also, see the menu bar entries related to window management, which replicates these same functions but can be bound to keys in the system settings.
Option-clicking the green button maximizes it similarly to Windows, rather than going fullscreen. I never used fullscreen just because of the slow animation it used, and now it makes even less sense on my new MacBook with the notch. It basically replaces the menu bar with a blank bar.
I will wait for you to discover these Keyboard Shortcuts - Press the `fn + ^` (that globe key + control) and then try `c`, `f`, and all of the four arrow keys.
Vulgarity aside, I can sympathize. For years I've been told by designers that discoverability and intuitive interacting patterns are so important, yet every aspect of modern design focuses so much on minimizing "distractions" that features go undiscovered. We get forced into suboptimal workflows and usage patterns because everything gets over-fitted to the lowest common denominator.
This is the biggest reason I love Linux. I can choose my own desktop, or even forsake the desktop entirely for a simpler window manager, without changing operating systems. Some are hyper focused on a tailored experience (gnome) while others let you configure to your heart's content (kde).
There's sacrifices to be made, of course, but not having to live under the oppression of Apple's beneficiary dictator designers is absolutely worth it for me.
Thanks for mentioning that. I have one hearing aid so I've had to take it out so I can wear both AirPods when I want noise cancellation at all with AirPods. (I can also stream to the hearing aid but it is very tinny, completely lacking bass.)
I detest the trackpad on my Windows (Linux soon) laptop, so I have to use an external mouse with it, but I use the "magic trackpad" on my personal and work macbooks including external ones without issues (except if I have to drag something very far; this three finger drag seems to make it nicer although it wouldn't work if I needed to make sure not to let go like when dragging files around). Just wanted to point out that there's a big difference.
I don't daily drive a mac anymore, but I seem to remember that it allowed you to hold the selection with one or more fingers, and move another finger on touchpad for the actual moving part. You could lift this last finger without letting go of the selection.
I wanted it to work, I really did. I even went so far as to buy an external magic trackpad, because people raved about it. That trackpad is in mint condition ... in my closet.
> Why? Because those individuals tend to spin something up, tell everyone about it (online, and offline) and then stop doing it few days later.
That's definitely me (most recent ones: using engineering notebook techniques but for my own life, and WOOP method), but I recognize that feeling like I've found THE solution when I'm only a few days into it, so I tend to wait and see, or if I tell someone I say "...but ask me again in a week or a month if I'm still doing it." (At least with the engineering notebook, I can still go back and use it to remember what steps and settings I used in KiCad or use WOOP on a new goal at any time. So it's not a total loss.)
I will say one thing that I have stuck with and is pretty useful is a morning checking and an evening checklist. I'm currently using a paper version with the days of March in the columns and the checklists in the rows, and X them off as I go. A slash for the one I'm doing now/next and X when it's done. Leave it blank (or write N) if I choose to skip it. As a back-up, when I can't get around to make a paper version (I'm planning to type in the steps in a spreadsheet so I can just revise and print it each month) I keep the lists in two Google Keep checklists. Those are great because you can reset the checklist each day for reuse, and you can drag to reorder it as you edit it, and you can indent one level to organize it a bit. The disadvantage is I might get distracted by notifications and stuff on my phone.
News to me. denhac has grown from 500 members to 600 in the last year since I joined. The space is constantly evolving and they'll be moving to a another larger location (again).
Can you scan my bookmarks? :) edit: i.e. if someone has a bookmark to a page on your site and it goes 404, then they are blocked for a year. You have no ability to scan it because it's a file on their local system.
There are actually other time signals around the world.
I had a Casio wave ceptor (one with analog hands which it doesn't look like they sell anymore; I should have kept it). Anyway, looking at a model that's currently available (WV-200R, but there are 2 other models available), its manual says it gets signals from "Germany (Mainflingen), England (Anthorn), United States (Fort Collins), [and] Japan."
I was curious so I looked those up:
Mainflingen DCF77 77.5 kHz
Anthorn 60 kHz
Fort Collins WWVB 60 kHz
Japan looks like they have Mount Otakayoda 40 kHz, and Mount Hagane 60 kHz.
There are also some other countries that have time broadcasts (e.g. France. Anywhere else?) but not that that watch uses.
There's also a station in Shangqiu City, Henan province, China, BPC 68.5 kHz
Casio brands watches that receive all 6 stations as multiband-6, and older ones that don't have the Chinese signal as multiband-5.
The analog display, chronograph watches like WVQ-M410-7AJF are delightful ; you can switch to timer mode and the main hands show the time ticking down (yes, they move counter-clockwise), and then switch back to normal timekeeping mode and the hands will move around the dial to set to the correct time again. Obviously at great expense to battery life, but it's solar powered. Unfortunately it's Japanese Domestic Market only, so you need to order it from a place like discovery mall japan. (The WVQ has a flimsy plastic - if you're willing to pay a lot more you could spring for the OCWS7000E ). Citizen has some GPS set watches.
Radio time signals used by watches and wall clocks are all in the 60-77.6 Khz range, probably best suited to small receivers and low power - other radio time signals are higher frequency. In the US, WWVH broadcasts at 2.5MHz, 5Mhz, 10Mhz and 15Mhz.
