  • I think it ends up being the same amount of work for me. Rinse rice (optional), figure out correct amount of water for that type of rice, place on heat until done. Rice cookers can effectively detect that there’s no more liquid water, but that isn’t the same as “done” unless you used the right amount of water.

    IMO, rice cookers are really handy if you are the type of person who eats rice as a staple food item that you buy in giant sacks and eat the same variety of every day. I have like 6 kinds of rice I rotate through, so I think it wouldn’t save me enough work to justify a separate gadget.

    I’ve never used one of the really fancy pressure cooker rice cookers, though, so maybe my feelings would be different.


  • Yeah, I definitely understand that. I certainly have things that I don’t use as much as I hoped (I’m staring at a solar panel doing nothing leaned against my wall). For me, I really need the resulting “thing” to be something that I will use/be excited about.

    That’s why, for me, fixing stuff that’s broken, upgrading stuff, or repurposing stuff you already own is good. Replacing a worn out jack is a relatively simple task that can turn an expensive brick back into a nice thing.

    The tools you need are not a very long list. You can get a cheap, crappy soldering iron for $6, solder for $4, a crappy multimeter for $7, and one of those magnifying glass/alligator clip things for $6 from harbor freight. Despite being poor quality, a lot can be accomplished with just those tools.

    I ended up buying a bench power supply for like $40, but you can just get DC power supplies from the bin of assorted cords at your nearest thrift store for basically free.


  • Wow, you couldn’t be more different than I am. Over the years, I’ve bought kits that had tutorials along with them, and I could never get hooked by them. I guess there’s better tutorials for things now than “make a bunch of LEDs blink in order”, so maybe the terrain is different.

    There are so many kits you can find online, and I think a lot of them are more or less interchangeable. I suppose it depends on what extent you want to focus on digital vs analog circuits, but given that you mention robotics, I would assume digital. Grab one of the kits that has an arduino or raspberry pi and a bunch of other components. In the grand scheme of things, components are cheap, but no one is going to ship you the 5 exact resistors you need, so you need to have a fairly large assortment to choose from for different projects. Kits are going to come with different components like digital readouts, joysticks, etc, so just choose one that looks like it has the things you would like to learn to use.

    It seems like kits are divided into “contains every part of a specific project” or “contains parts for 1,000,000 potential projects, and here’s a booklet of tutorials for some”. I prefer the second, but you could prefer the first depending on if you want to go right for robotics use cases.

    Personally, my best learning has been through repairing home appliances and stuff like that. Even just “necropsies” on broken things to understand how they work.

    Something that you’ll notice with electronics these days is that sometimes the difference between a base model widget and the “premium” widget that is 1.5-2 times the price is the addition of a handful of cheap parts. They might be easy to put in and cheap, but they are going to remove as many costs as possible for the base model. For example, a $350 dollar espresso machine with $100 of extra parts added can easily compete with a machine that costs $1000 or more.





  • All news has a bias, some news just doesn’t tell you what their bias is. I’m not advocating for intentionally aiming for biased news, I’m advocating for knowing what the bias of the author/editor of the story is, so that when you read it, you know what conclusion they might be trying to lead you to. Even if a journalist tries their best to be impartial, that’s not possible, and like I said, it’s very easy to tell a one sided story with exclusively facts.


  • News sites often have multiple feeds, but many these days don’t. And the feeds still aren’t as granular as I’d like sometimes. My regional newspaper has a feed for news more specifically local to me, but it’s bogged down with children’s sports and obituaries.

    I think my dream setup would allow some intelligent filters to get rid of any categories I just don’t care about, and any “top 8 widgets to do X” filler advertisement articles. Also, a way to lump together all news articles covering the same story, so I could either choose which outlets to actually read/compare, or mark all as read.





  • This whole post is a good illustration to how math is much more creative and flexible than we are lead to believe in school.

    The whole concept of “manifolds” is basically that you can take something like a globe, and make atlases out of it. You could look at each map of your town and say that it’s wrong since it shouldn’t be flat. Maps are really useful, though, so why not use math on maps, even if they are “wrong”? Traveling 3 km east and 4 km north will put you 5 km from where you started, even if those aren’t straight lines in a 3d sense.

    One way to think about a line being “straight” is if it never has a “turn”. If you are walking in a field, and you don’t ever turn, you’d say you walked in a straight line. A ship following this path would never turn, and if you traced it’s path on an atlas, you would be drawing a straight line on map after map.




  • This is especially weird because the Netherlands does not normally permit dual citizenship.

    It seems like many (most?) countries don’t like/recognize dual citizenship. The way it ends up working is that each country doesn’t have the power to tell the other country that someone isn’t a citizen. Each country just enforces it’s own citizenship within it’s borders. If you had US/Netherlands citizenship, and use a Dutch passport to try to enter the US, you will probably get yelled at by customs if they realize that you are a US citizen. They can’t stop you from entering the US but they can hold you for a while and pester you.

    If you have a US citizenship but live in another country, most of your income will be exempt from US taxes (unless you are a millionaire, in which case you probably aren’t paying many taxes anyway).

    A similar thing happens with countries that have mandatory military or civil service; you can be required to travel back to serve.


  • You essentially gamble a little bit. Most people get insurance through work (or they are part of a family plan). Generally, you’ll have a few plans to choose from. If you are older, or have recurring issues, you might pick a plan that’s a little more expensive, but covers more costs. If you are young and healthy, you might pick a cheap plan, essentially betting that you won’t really need healthcare other than your yearly checkup and some vaccines.

    The biggest thing with healthcare in the US is that it’s very complex. Even if you have insurance that should cover something, it can be hard to find a doctor that’s part of your insurance, so people often put off going to the doctor, which is part of the reason why costs are high. Teeth and eyes have separate insurance cause they are optional, apparently.

    You basically have “premiums” that are your monthly payment. If you get your insurance through work, they cover a percentage of that; generally a pretty hefty amount of it. They usually don’t outright tell you what percentage, though, so many people think insurance is cheap, and get a rude awakening when they lose a job, and suddenly can’t afford $1000 a month when they used to be paying $100. Those premiums are taken out of your paycheck pre-tax, too, which gives you even more of a benefit if you have a job.

    Depending on the “style” of the plans, they cover things differently. They all (I think) cover “preventative care” completely, which includes your yearly checkup, vaccines, and birth control for women. After that, some plans have “co-pays”, which are set costs for a few things, like $25 for a normal doctors visit, $50 for a specialist, $100 for an emergency room visit. Some just cover a percentage of those costs, and some don’t pay anything until you hit a limit (the deductible). Finally, there’s an “out of pocket” limit. That’s most you’ll have to pay in a year, after which point the insurance covers everything.

    All together, I pay less than $1000 a year for healthcare, but if I got really sick, and needed a bunch of expensive healthcare, I would quickly hit my out of pocket maximum, which I think is like $6,000. I could cover that, but many people cannot cover an expense like that on short notice.

    The number on bills is very misleading. The hospitals know that insurance will negotiate down, so they start high, and then after the negotiations, insurance will pay some or all of the remainder. If you don’t have insurance, you typically don’t pay that whole number on the bill, either, cause the hospitals recognize that they dont have to adjust it up for the negotiation. You can still negotiate on your own, though.




  • It definitely comes and goes in waves, I think. The interplay between infrastructure and economy is key. Your economy is dependent on things like ports, rails, pipelines, cables, roads, powerstations, etc. A country can’t continually overhaul those things, and once they’ve invested in them, they are stuck for a while. This leads to weird situations where one country that’s been behind for a little while can pass another country.

    The US electrified first, and when Europe electrified, it used higher voltage, which allowed for more efficient home electrification, while many Americans are stuck with slow kettles, and clothes dryers, water heaters, furnaces, and stoves that run on fossil fuels. Similarly, widespread internet rolled out in the US first, but countries that came later were able to get higher speeds.

    The economy of most countries, especially the US and China, is a house of cards. While there may be more investment, there’s also more risk, and more inequality. Germany may be more stagnant, but it also may be more stable. It doesn’t matter if the GDP per capita is higher in the US than Germany if the average person has no healthcare, paid for schooling, or social safety net.

    One of the biggest lies (maybe more of a “spin” than a lie) that has been told over the past century is that the “economy” is the stock market, gdp, net import/exports, commodities, etc. Those are all important, and economists like to use them cause they are easier than getting to what really matters to most people.
