This is cool, but it mostly doesn't have what I would call components. When I think about components, I think about discrete parts, like resistors, diodes, IC's etc. most of what they have I would call connectors, cables, modules, or circuit cards. If you look at the wikipedia article on Electrical components you can see what I mean.
I was at the pantages theater for one of the shows. There are some clips at the end of the audience and there is a very brief moment where you can see me in the audience with my friend. My 1 second of fame. It was a great show and being able to see the video once in a while over the years has been a real treat
LeanDojo looks cool! I will check it out. I did the natural number game in lean 3, and was excited to see the author of "How to Prove it" had written an online book, "How to prove it with Lean" to as an accompaniment to the book, but it was written in lean 4. I decided to redo it in Lean 4 (still working on it) and had some troubles but was super happy with the responses I got on the Zulip Chat. It was a bit tricky to install it but the lake system seems like a big improvement over how I installed lean 3. I used the emacs version of lean mode for lean 4.
I think anytime you move past the lumped circuit model you can run into trouble. This includes digital circuits with fast edge rates. On the other hand a close reading of a component manufacturer's application notes and reference schematics can help a lot of people who may have only limited formal training in electrical engineering.
I haven't gone in a long time but I used to like buying DVDs at Bookoff. Its a japanese second hand shop but they had a good selection of English language dvds and cds. It looks like they only have locations in Southern California and New York.
I still have netflix dvds, although I only get one now and usually take a long time to watch it. But I started January 2001. I bought an expensive (at the time) dlp projector and make a large screen and stand out of blackout liner and some wood from home depot that I would put up in my living room to watch it. My kids were young so I would watch movies in the dark after they went to bed. They still give me a hard time about "Goodbye Dragon Inn" which they say was the worst movie ever, and my daughter cried at the end of the Bicycle Thief. We did not (and still don't) have cable tv so that and VHS tapes was how we got entertainment. I'm not sure when it stopped being a thing for us, but gradually things like Netflix streaming and youtube became more of what we watched. So I don't think I will really miss the service so much but I think I held onto it for more or less nostalgic reasons.
There are some places where I still experience "Things Come to Us". The open library on the internet archive is one. Worldcat is another although I still have to reserve/pick up the items. Using RSS and w3m to read news is another. You can use something like UserLand to run w3m on a phone, and the terminal program is pretty slick.
I've been reading older books on computing on open library, like "The Second Self: Computers and the Human Spirit" written in 1984 by Sherry Turkle and it's fascinating to see the questions people were asking back them. My favorite quote from that so far is this:
"That question is not what will the computer be like in the future, but instead, what will we be like? What kind of people are we becoming?"
It's interesting that he started with that topic. As opposed to voltage, current , RC circuits, etc. He's got quite a few topics, like emitter followers and op amps. But I think he's a bit below the level of what people need in order to create useful PCB level electronics. I think something like this would be so much more useful if it was tied to an existing book on the subject, like for instance "The Art of Electronics". Which actually doesn't cover device physics but start with just transistor and diode models presented as facts.
I very much wondered the same thing. I've had a couple of occasions where I really wanted a numerical answer to some finance questions, like for instance keeping an IRA vs paying taxes and converting to Roth. And I want it to take into account my tax burden, how much cash I have available, etc. The simplest way for me to do it was python scripts and Beancount + Fava. I don't even try and use it for keeping track of my finances, I use quicken for the simple reason that I know my spouse can use it as well. I didn't see "tax planning" on the features for Ghostfolio, this seems so very basic to me that I couldn't consider using it. I understand why in a way, there are so many situations. Of course if I only have to model my particular situation it's much simpler to just write a simple model in python.
I retired early (age 49), but I took a four month leave of absence about 5 years before that. Trying a leave instead of retiring was one of the few things I read about early retirement that made a lot of sense.
I gather some people "miss" work or get bored. I didn't miss it when I took the leave and definitely was not worried about being bored when I did retire. Anyway if you are thinking of early retirement I highly recommend trying to take a leave of absence first. You might have to be willing to quit to make it happen though.
I love my brother black and white laser printer. But I print infrequently. The problem I had with inkjets for years and years was dealing with clogging if I used them infrequently. Does anyone know if the color canon eco tanks work if you only print infrequently? Or do they clog? Some cursory searching sounds like clogging is still a problem for infrequent users.
20 year zen practitioner here. Don't expect meditation or buddhism to make your problems go away. If you have an acute mental problem like depression, bipolar syndrome or are suicidal get professional help first. Then go study buddhism. Some teachers will even ask you to sign a waiver acknowledging this.
My spouse was a sw engineer who became ft stay at home parent shortly after our second child. Yes it's not how much you make but how much you can save after that counts. Certainly she saved us a lot of money. In my case the intangible benefit of never worrying about my kids cannot be overstated. I really think it made a huge difference. I live in a community property state and I feel sorry for stay at home spouses who don't have this safety net. For the most part I think they deserve it.
John Markoff wrote about this in his 2005 book "what the dormouse said". More than just psychedelic drugs but the whole connection to the 60s counter culture. I found it a pretty interesting read at the time.
I travelled to India and Nepal right after high school from Los Angeles in 1982. I bought a copy of Tintin in Tibet in India and it is still on my bookshelf all these years later. Really nice to read the backstory about Chang.
My understanding was the reason the US didn't end up transitioning to chip and pin was they couldn't transfer the liability in the case of compromised pin. That is the consumer liability would still be limited to $50. So there was no incentive for the card network to roll it out in the US. You still get the benefits of the fact the card cannot be copied which is significant.
You might consider trying a muse 2. I bought one used on eBay for $125. There is a very good app mind monitor you can see what's going on quickly and get captures and python options like muse-lsl for doing your own capture and analysis.
I borrow a lot from my local library but often they are unplayable somewhere in the middle. It can happen with Netflix also but it seems much less frequent.
There are many federal laws dating back to the 60s prohibiting race based discrimination. There is nothing preventing someone taking a case to court who is asian or white.
I found the eevblog tutorial videos very helpful in setting up my office for soldering and getting comfortable doing through hole soldering, connecting wires etc.
Part 3 is surface mount which I don't do much. A friend I had who is a skilled assembler turned me on to chipquik flux and kapton tape to hold down the parts and that helped immensely
I came to say this, the Japanese have the solution, they use a different alphabet for imported foreign words although less so for Chinese. Even better they change the pronunciation and drop syllables to make the imports easy to say. Maybe other languages can invent some kind of stylizing like italics to indicate words are foreign.
You can do turtle graphics in scratch. I have taught some beginner scratch classes at my local library and used the turtle graphics feature for the example for the class
Recording meditation sessions. I played around with one I borrowed from somebody in 2015 but it was just unreliable for longer 30 minute sessions. It's come a long way in terms of third party software and tutorials on removing artifacts from the data. There is a phone app mind monitor that makes it very easy to look at frequency domain data and make recordings which you can import into tools like eeglab.
I've been connecting a raspberry pi to a muse headset using the muselsl python library. But that only has 4 channels vs 8 for this one. I bought a muse about a year ago used for $125 on ebay, this board is $350 and you would still need to buy the electrodes and make a headset. I think the price is fair and it seems pretty competitive with openbci boards, but I think if you really wanted to just get started you could get going with a muse for a lot less and a lot quicker. The muse is finicky to get good connections, but I don't have any reason to believe it would be that much better with my own homemade headset with dry connections. Also it says for safety reasons you have to run the pi on a 5V battery which might not run all that long depending upon the size of the battery and which pi you are using.
Will I still be able to use Bear in 2033? I'm pretty sure I will still be able to use org mode and emacs. I agree org mode is not very good for collaboration but for that I think really things like Google keep and Google docs are much easier. I liked Wunderlist for that but alas it's gone.
My daughter in law who's Swiss introduced me to this. I can't remember but I think it was on New Years Eve. I remember before VHS tapes they were quite a few shows that were always aired around the same holiday time and we all watched them together (with commercials!). Fun times but like catching your new favorite song on the radio those times are gone.
