    Me, a nerd: its just a joke don’t go off on a tangent, dont go off on a tangent, dont go - just let it be… I just… I just…

    I NEEEED IT

    So achtbually, nature works with transcendental real numbers on the complex plane with uncountably infinite precision.

    Lets break this math nerd statement down in a way normal people might understand. First, most numbers are multi-dimensional and live on a plane instead of a line. The straight integer number line like 0, 1, 2 is just a small slice of the plane. In this plane, imaginary numbers occupy their own dimension. Complex numbers which are made of both real and imaginary parts occupy another dimension.

    Moreover, most numbers are also infinitely precise thus being uncalculatable. Their decimal places go on forever and ever without repeating or being representable with a ratio of integers. Its why we only have good approximations for pi instead of an exact pinpoint knowledge of it. There are methods to get closer and closer approximations but you need an infinite time frame to complete that unending process.

    Theres actually somehow more uncountably real numbers than countable integers and ratios, even though they are both infinite. There are more decimal numbers between 0-1 than there are integers between 0-infinity. One form of infinity is literally bigger than another, and that bigger infinity is the one nature likes working with.

    Moreover, most of our universal physical and mathematical constants are transcendental reals because nature gets a hard-on for baking multidimensional fractal holomorphic topology and complex nonlinear equations into its magical abstraction bullshit logic.

    Theoretical physicist during the 20th century were VERY salty about finding complex and imaginary real numbers in their physical equations. Since it implies that complex numbers arent just imaginary tools of abstrction but somehow “real” and affects the universes physical machinery. Nonlinear dynamic equations put a bullet through the brains of classical scientific determinism. Thank you very much, chaos theory and entropy.

    It’s not that we invented imaginary numbers, its that they were the missing piece to fully complete our understanding of algebra. With them, we finally graduated from cave man linear algebra, to discovering holomorphic dynamics which model the way natural systems actually work. After 2000 years of banging basic logical abstractions together to make a enough decent sparks of discovery for a real smoldering fire.

    Computer processing power sure helped to visualize these higher dimensional topologies for our little monkey brains to process with our eyeballs in real time instead of just thinking about this stuff in the minds eye. I sure cant visualize a 4D hypercube let alone a 20ishD hyperstructure that AI image network picture forms brought down to three dimensions.

    Really its a miracle that we have even a thin narrow portion of numbers we can compute, all our regular integers and ratios are islands distanced apart by an infinitely deep ocean.

    In case you were wondering about the stuff in the image: Multidimensional AI activation map showing how and image AI organizes its knowledge on a neural network. Similar concepts or images are closer together.

  • My niece and nephew ended up in the system and I felt morally obligated to put my life on pause and help my parents get them adopted and taking care of them. I couldn’t even move back into the house as each child required their own room so for the past year I’ve been living in a tent in their back yard. The whole ordeal has been emotionally taxing, but also kind of rewarding in weird ways I didn’t expect.

    In terms of the kids, its nice to be able to positively influence their lives and show them the kindness, love, and guidance I wish I had. When I make them laugh or they express gratitude It makes me feel like my existence wasn’t a complete waste.

    In terms of living in a tent? I came to love it. It taught me to overcome many issues and made me much more resiliant. To better understand the difference between convinence and necessity. Most of the things you think you need, you really don’t.

    From the basic survival stuff like adjusting to the climate, to building my own solar system, to learning how to clean myself and use the bathroom without running water. I minimized my entire lifestyle, let go of all the useless trinkets I thought I needed, and found the true basics of what a person really needs to be comfortable.

    I also learned how to confront my fears of what other people think of me for daring to live an alternative lifestyle in their view.

    I feel so mentally different from the person I was a year ago. More capable and confident. I feel like I can do anything, be anyone, go anywhere. I feel kind of great about myself and my situation in life. I feel like I’m an okay person living a genuine authentic life. Helping out my family while getting myself figured out.

    Also given the current housing and renting market, I can’t help but feel like I’ve figured out a cheat code. "Affordable housing? That converted out car looks good enough to me. "

    I dont think things would have gone this way had the kids not ended up in the system.

    I’m very glad that I’m transitioning out of being a gamer at this point in my life. I still enjoy a good game from time to time but I genuinely have had my fill and have little desire to spend any more of my finite life staring at a computer monitor for hours risking an RSI just to chase those fleeting feelings of “fun”.

    I have my portable folding 200w solar panels on the ground and run about 20ft of weatherproof cabling running along the ground through a small inlet hole into my residence. They connect to my battery system which is located in a good central spot for all my electrical stuff to comfortably reach. Everything I own that runs on electrical power that cant be powered with portable rechargable battery banks is located in the same room as my batteries.

    I can deliver DC power through car plug ports, USBC-PD 100W and regular usb A outlets. The 600w AC inverter is useful for brewing cups of coffee, running fans, and turning on a desktop pc for advanced GPU workload stuff. Its important to keep that ac inverter off most of the time especially at night so prefer using car plug adapters and USBC-PD to directly power most of my DC appliances with variable voltages instead. From the car plugs and usbc-pd charger ports, I run my dc appliance cords to my devices which are usually 6-10 ft long. My laptop is usually powered up through a car port travel adapter but I can also use USBC-PD and an adapter bit if the car ports are all taken up.

    Thank you for showing interest if you want to know anything else ill be happy to explain. lowtechmagazine’s “Slow Electricity: The Return of DC Power” is a great read on the subject the info has been very useful for my purposes. They cover residential dc wiring like we are talking about and its located around the end of the article in the ‘How To Limit Cable Losses’ section.

    You got it man, right on. I would like to give you some more information about the usbc-pd stuff and some of the things I figured out with it. So here is a link to the farsense usbc-pd to standard DC 5.5x2.5 adapter with manually selectable voltage based on button press. This cable is the most important part and I will explain why its so important. USBC-PD essentially requires three things to work right.

    The first thing is a charger(the DC to DC inverter in our context) ideally rated at either 65w or 100w as both of those support up to 20v the difference being 65W can only go up to like 3.25 amps or something like that. The simplest and cheapest dc to dc chargers are usbc-pd car plug chargers which convert the 12v from a car battery to the required voltages. The anker one I just linked is a little pricy you can find them for cheaper but it seems good quality and I like the cable I bought from them.

    Speaking of, the second thing you need is a USBC-PD power cable that specifically supports the same wattage your charger outputs. Not all of them are rated the same you gotta use a specifically rated cable that handles higher voltages. If you use a 100W charger gotta get a 100W cable. I’ve had good luck with this anker one

    The third and most crucial thing to understand for our purposes, is that you need a communication chip on the appliance side that tells the charger/inverter what voltage to send. The nice thing about that farsense manual voltage selector cable is that it has that communication chip built in with all the different voltages to pick from. Thats the real secret sauce of this setup. That cable and its ability to choose voltage levels is the heart of it. All thats left is to track down the specific dc 5.5x2.5 to X adapter bit and select the proper voltage on the cable and its good to go.

    There are USBC-PD adapter bits that have this chip built in for a specific voltage, commonly for laptops at 19-20v. If you manage to track down the proper usbc-pd to barrel plug adapter at your specific needed voltage it will cut out having to manually set the voltage each time you plug it in compared to the farsense cable. But it may be hard tracking down such a specific adapter bit.

    I am off-grid for much of the time so I rely on an entirely DC to DC system. 200 watts of solar panels power up my batteries which supply 12V at a capacity of about 400 watt hours. So for many appliances like laptops and speakers and computer screens which use DC power it makes sense to try to convert the voltages directly though other means than the typical AC to DC power plug supplies that you usually use in homes. Doing this I can cut down total power consumption for each device down by about half which is really important for conserving power on a limited energy supply.

    In a theoretical scenario you could totally run a seperate voltage line for DC energy through a house, though this has several complications. The main drawback of DC energy is that the lower the voltage the more resistance losses you get running power through a foot of cable. So the cable losses would become signifigant after running 200 feet of cable probably less even. You could bump up the voltage to 48VDC for longer stretches of wire and to power high end RV appliances but now were loosing some of the safety that comes from a lower voltage DC system. Im not familiar with commercial solar installations in homes but I think its easier and more economical to eat inverter losses and use the batteries to supply AC power using preexisting wiring. If you were building a offgrid home its a design thing to consider, reducing and centralizing wiring and appliances.

    Thanks, glad to have inspired you! The other person who replied is spot on. I have an entirely DC system so my main advantage comes from cutting out pointless double-conversion from dc to ac back to dc again. Powering on an DC to AC inverter is a parasitic draw that consumes enough power to eat through a good amount of battery capacity if left on by itself. Then using that AC inverter just to power another inverter to step back to DC introduces even more losses and parasitic load. So, its worth my time to try figuring out ways to directly power devices by directly converting DC to DC voltages and cut those needless loads out greatly boosting total efficiency.

    USBC-PD technology is an incredibly useful innovation for direct variable dc to dc voltage supply. Specifically a 100 watt usbc-pd charger can supply 5v,9v, 15v, 20v at up to 5 amps (5Ax20V=100 watts). A car cigarette plug can supply 12V at 10A or 120 watts of power. Together they can directly power a great many household DC appliances off of batteries powering a DC to DC inverter.

    For some examples:

    A 24" lcd computer monitor at full brightness consumed 50Wh through AC inverter. It was brought down to 25Wh running through DC inverter. On half brightness it consumed 15Wh and 10Wh at minimum brightness.

    A thinkpad laptop full brightness was 25wh idle -50wh full load, then brought down to 12-20wh.

    My nintendo switch game console docked into the lcd screen consumed about 15-20Wh with inverter, brought down to 10Wh.

    Desktop dry herb vaporizer (Arizer Extreme Q): 80Wh heating up, 30-50wh idle brought down to 50Wh heating up 15-25Wh idle.

    Electric blankets. During the cold months using my electical energy to help keep warm is very important to me. But I cannot keep a regular house electric blanket on for more than an hour or two. I could not keep a car plug blanket on overnight at 80wh. I could keep on a USB powered blanket on overnight at 10-15Wh. And you know what suprised me most? It was damn warm, when I figured out the right way to sleep with it. Have to sleep on it as a matress warmer and layer some heavy blankets on top and let it warm up for an hour or two. But it works and works well. The USB blanket doubles as wearable poncho too which is nice. I wish a USBC-PD one existed with variable wattages.

    So as you can see each time I macguyver a way to directly power these devices the total power usage is cut by almost half per device. To someone else who can afford an array of solar panels and a massive bank of batteries they can get away with not caring about saving 20Wh here or 15Wh there. I have a very modest system of 200watts solar feeding into ~400Wh battery capacity total so these savings mean the difference between my batteries being dead overnight and having lots of spare juice left over to brew a cup of coffee with those AC inverters when I wake up.

    Of all these devices listed, the LCD monitor is one that has a noticable parasitic load even when the screen is off it consumes a noticable amount of power at idle. The way I would deal with most instances of parasitic draw like this is to find a product throws a physical switch to manually cut contacts with the DC-DC inverter when not being used. In this case a car plug extention cable with a knife switch built in would work great.

    After switching to solar DC and batteries I suddenly cared a lot more about ac/dc power inverters needlessly wasting my limited energy supply.

    Slowly I figured out how to power my devices without ac outlets. Mercifully 5v,9v,12v,19v at 1-5A are pretty standard values for most lower powered DC appliances.

    A good DC barrel plug 5.5mm universal adapter kit, a usbc-PD adapter cable with manually selectable voltage levels to 5.5mm barrel plug, and a car plug to dc barrel plug universal adapter kit have taken good care of 95% of my adapter woes.

    It feels sooo good to figure out how to power something directly with USBC and see the wattage drawn get cut down significantly.

    Whats my point? If people knew a little bit more about the finer details of power supplies and dc barrel plugs most of their box of junk cables could be phased out with confidence. If you have 20 year old electronics with some weird incredibly specific voltage and barrel plug I would heavily consider just getting a new version that runs on usbc-pd or a more standard power rating. And if I ever need an old video cable? You’d better believe amazon and eBay still got it.


  • You can put a SIM card in some older thinkpad laptops with that upgrade option. Some thinkpads have the slot for a SIM card but not the internal components to use it. So make sure to do some research if that sounds promising.

    There are VOIP phone line services like JMP that give you a number and let you use your computer as a phone. I haven’t tried JMP but it always seemed cool and I respect that the developed software running JMP is open source.. The line cost 5$ a month.

    Skype also has a similar phone line service. Its not open source like JMP and is part of Microsoft. Usually thats cause for concern for FOSS nuts, but in this context its not a bad thing in some ways. Skype is two decade old mature software with enough financial backing from big M to have real tech support and a dev team to patch bugs, in theory. So probably less headaches getting it running right which is important if you want to seriously treat as a phone line. I think Skype price depends on payment plan and where you live, so not sure on exact cost.



  • I was a big fan of odysee but once LBRY lost to the SEC I figured it would die or change horribly. Im not sure who owns odysee now, how hosting works on it now that LBRY has been dissolved, or whos mining rigs are running the decentralized lbry blockchain that still presumably powers odysee. I need to know the details in clear detail before I trust it again on a technical level. I am more skeptical of crypto now and think a paid patreon membership peertube instance may be the best way to go. Peertubes biggest issue is scaling hosting cost as it gets bigger and donations can’t keep up as well as lifetime of an instance. If I host my videos on your site and a year later it goes dark or they were deleted because the server maintainer just didn’t want them taking up space, thats kind fustrating.

    Thats good info for low spec laptops. Thanks for the software recommendation. Need to do some more research on the model you suggested. I think you confused me for the other guy though. Im currently working with a six core ryzen 2600 CPU and a RX 580 GPU. edit- no worries we are good it was still great info for the thinkpad users!
