  • 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.





  • A huge problem with the wine industry in America is that they’ve always tried to position themselves as a premium product with respect to other forms of alcohol. With respect to the information available to the consumer, the pricing seems to be random. Products that are aged understandably are going to cost more, and huge brands should be cheaper than small brands. Other than that, prices just seem to be set to correspond to whatever market segment they are targeting. A $20 bottle of wine may taste way better than a $15 bottle, but it could also be worse. There’s no indication of what could make the $20 bottle better than the $15 bottle other than the fact that it’s more expensive. Some brands put a little bit more info in, like the percentage of grapes, and sometimes they tell you where the grapes came from, but most consumers are just going to grab the cheaper bottle.

    Contrast this with beer, where you know higher abv=more ingredients=more expensive, aged beers are more expensive, and beers from smaller or foreign breweries are more expensive. Breweries often tell you the exact ingredients that went in, so you can get a decent idea of what a beer will taste like before ordering, and you can make an informed decision to buy slightly more expensive products.

    Wine is a little more tricky because there are fewer ingredients, and less processing, but they could absolutely give way more info. The wines that are good just try to market it as the magic of terroir in a bottle, rather than actually pointing out how and why they are better or taste different.



  • 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.



  • That lance Hedrick video had a lot of good relevant info.

    I’ll add that the definition of “light” changes as much as the definition of women’s pants sizes do. Its essentially “vanity sizing”, but for flavor. Most consumers, at the end of the day, want their coffee to taste exactly how they are used to, but they paradoxically also want to be having something “different” or “unique”. It’s why Hawaii is full of roasters selling $70 bags of coffee that taste the same as $8 grocery store bags.

    Roasters have to weigh whether to give accurate info that will appeal to us nerds, or whether to aim for the general populace. There are probably many roasters who legitimately don’t know better, but I’d reckon many roasters are just making the economical choice.




  • 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.
