What the hell is a Typescript or: Creation ideas above my skill level

I'm a graphic designer. I've been working in the field for nearly seven years now, two of which in an actual agency. One afternoon I started on a project that was born of more or less pure spite - I love the annual art trading game Art Fight, but absolutely loathe how the game is run, how it comes completely crashing down every year due to people trying to access the site all at once and them not having any contingencies in place, and how the leadership there is apparently only concerned with donations and little community outreach. If you're unfamiliar, artists get sorted into one of two teams, upload their original characters with reference sheets and then draw characters belonging to the opposing team's members. It's great fun, and I tried volunteering for them, but the fact that I'd've to sign an NDA just to be a moderator is just a step too far. For those unaware, the Art Fight team was also caught embezzling donations in one of the last fights, 2022 if memory serves.
So I did what I do best. I started drafting user stories, did UX research, sketched, drew and designed what I'd think would solve all the problems with Art Fight. The result I called PICTOCLASH, and while the process to make and prepare the design took me about four weeks from start to finish, I knew I couldn't actually make the thing work. Disregarding the fact that the Art Fight platform is anaemic and runs on outdated PHP, has no optimisations for image storage or user content and does not buffer or queue database interactions, it's still a massive lift. We don't have numbers on how large AF is, but suffice it to say that it's far larger than any hobbyist project can be without VC involvement.
I was convinced, though, that if one just... approached the problem differently, maybe with modern technologies, the Next.JS I kept hearing about from my web design peers, maybe a shiny new database like Postgres, state management, all the things I know next to nothing about, this could work. My project could work. Yes, it's a lot of work, but it wouldn't be impossible. With a team of developers, all believing and contributing to the project in an open-source way, that's doable. Eminently realisable, even.
So I started. I began reading documentation for TS, Next, React, Prisma, Postgres and all the other things I'd need to read up on. This was maybe half a year ago. But damn, programming got hands. Even the Me-ChatGPT-Dream-Team wasn't enough to have me wrap my head around so many concepts here. I'm a front-end guy, that's for sure. I got my ass handed to me, and in a month, I barely have a login system, and looking at GitHub I could have just went with any of the many pre-rolled solutions.
Which just led me back to my original point. I have three hundred-odd lines of barely functional typescript that holds up an incredibly slow login system. I'm not cut out for this project, and I need to accept that. I'm a designer, I know PHP, I can write valid JavaScript, but... application development? That'll forever be a realm locked off to me.
And of course, the easy way out would just be to look for developers. But I can't do that, at least not without significant risk of falling into the "I had an idea for an app, you wanna make it?" brand of parasite. I'd feel dirty doing that, even if I know that I could more or less to front-end and every visual component by myself. In fact, I have done that. It's just the app part that's missing, and that's unfortunately the major lift.
How do you people cope with this? Because it's not been the first time this happened to me. I keep putting off learning 3D modelling out of exactly that reason, that I could just hit a wall no matter how hard I try. It's frustrating, and looking back how easily I picked up other disciplines in university it really makes me wonder if there are some things my brain just can't learn. I don't think I'm ready to accept that.
Edit: For anyone interested, I uploaded the abridged design document to my website.

I've recently come back to studying German, after having taken a small break for a few months for a new job.
My main form of study is immersion (I recently stumbled across the books of Walter Moers and haven't looked back since) and conversation practice on iTalki.
Nowadays, I try my hardest to only buy tech second-hand and preferably as future proof and modular as possible. My go-to machines are a fully modded Lenovo Thinkpad T430, and a more humble Thinkpad X230, both running Linux (Ubuntu and PopOS respectively). They work just fine for my basic needs (mostly surfing, some occasional streaming and word processing). But they struggle during my conversation lessons on iTalki or Zoom, most of the time either overheating or freezing/stumbling. I realize this might be a Linux problem, but I have also found the web camera and built-in microphone on both machines to be really inadequate for video calls. I gave up using my own laptops for my language lessons over a year ago, and now have resorted to stealing my partners Macbook, which isn't ideal.
Do you have any recommendations for any more recent laptops that would offer a better video conference experience, while offering at least a removable battery? Pricewise it would be great to be find something below €500 used.

Inspired by the recent post about Arrival / The Story of Your Life
The idea of linguistic relativity ... is a principle suggesting that the structure of a language influences its speakers' worldview or cognition, and thus individuals' languages determine or influence their perceptions of the world.
There's, of course, a lot more to it, many variations, and all still at least somewhat in dispute.
Nevertheless, as the title says, assume it's true, and speculate on which languages would be the most interesting to learn from an "expand your mind" perspective.

I'm an intuitive learner. I learn by constantly asking questions, the answers to which i can then effortlessly remember. By messing around and seeing what happens, and then asking why. Lecturers have been enthusiastic about my approach but said I'm going to struggle because the school system in my country wasn't designed for people who learn like this. I want to kill myself.
The way I see myself learning stuff:
- Here's a fresh store-bought kombucha scoby
- Here's a scoby from the same store that I've been growing for 6 weeks
- If I sequenced the DNA from equivalent cells in each of these scobys, would I find any differences? Why?
Same with my latest interest: Law. I've watched a few (mock) court cases and researched whatever questions I came up with, to get an understanding of how courts worked, and had a look at the cited laws.In physics tests I end up running out of time because whenever I forget an equation I need, I try to intuit/derive it, which I would manage given enough time.
The way we are actually expected to learn stuff:
- Listening to a lecturer talk for 12×2 hours, and/or reading the referenced literature. Anything mentioned could be on the test.
I have been trying to do it the mainstream way anyway, but I am getting such bad grades that I've had to re-take a year. Even if I found strategies to help me focus I'd still clearly have a competitive disadvantage to people to whom this approach comes naturally. This feels unfair since I know there is a way that I could learn about my field as effortlessly as other people do listening to these lectures.
How does someone like me succeed in academia instead of just scraping through?
I understand that my prefered methpd which I outlined is what you do at PhD level. I'm afraid that by force-feeding my brain all this information that it currently sees as irrelevant, I will kill my curiousity, which I don't want to do because it's the thing that's allowed me to get this far with practically no effort (I went through the archetypal Smart Kid thing in middle school).
For context, I'm in 1st year bachelor's biochemistry (repeating the year). Although I think that at least in my country, all university courses have the format I described.
Since I am also struggling with ADHD I honestly feel like giving up on Uni and going for some sort of apprentiship-style thing. I would like to have a degree though because it's sort of a requirement nowadays and I am genuinely interested in my subject area. Alternatively, what kind of professions seek my method of inquisitively deep-diving into stuff, as I described?

Recently I have been trying to learn a new language, because I need to more so than I want to, and it's been really tough. While this isn't a shocking revelation, I had a bit of a deep dive to try and think about how and why I don't like learning a language. I do enjoy learning about a great deal of other things in my spare time, why not this?
So I pose the following questions to you:
- What kind of thing do you enjoy learning about?
- Do you find a specific format or type of learning helps you when it's tough?
- Do you always use the same format of learning?
- What do you not enjoy learning? Why? Try and explain what it is that makes it difficult compared to above.
Be interested to hear how different people feel.

Hi logophiles! I am a total word nerd. Over the last six years--mostly accidently--I ended up creating a bunch of vocabulary learning materials and spent way too much time thinking deeply about how we learn new vocab and how to teach it. My story: basically, via word of mouth, people with kids taking the SSAT and the SAT kept asking me for my materials which I continually iterated on as I got feedback. It wasn't my day job, lol, it wasn't even a side hustle.... just an obsession :) As I shared my "system", I kept dreaming of even better ways to make vocab learning effective, easy, and fun.
Some interesting things about learning vocab. The "keyword method" is extremely effective. (The keyword method is associating a target word with a similar-sounding word (the "keyword") and then creating a vivid mental image connecting the keyword with the target word.) [Ávila & Sadoski, 1996; Shapiro & Waters, 2005]. Further, connecting the new word and its meaning to your own personal experience is much effective than rote memorization. ("...engaging in deeper semantic processing and relating information to personal experiences can activate distinct neural circuits compared to those involved in rote memorization." [Andreasen, O'Leary, Cizadlo, Arndt, Rezai, Watkins, Ponto, & Hichwa, 1995]).
There are a lot of other cool things I discovered on my (research-obsessive) path to make learning vocab radically easier. A core driver for me has always been thinking about the epistemology of word-learning. What does it mean to "know" a word? "Knowing" a definition is different from truly knowing a word, where you can deploy it effortlessly when the context is right. That led to endless rabbit holes of learning about polysemy, colocations, and a whole lot more.
The first day I saw Dalle my jaw dropped. This was it! This was the missing piece for learning vocab 2x, 3x, 4x(?) more efficiently than has ever been possible. The image generation AI tools can make a custom image that packs in your own favorite keyword mnemonic and your own personal story into a cool image. Whoa! Because what has been my total obsession could finally be created in the real world, I teamed up with two good friends with the technical chops to build what had been percolating in my brain for six years. We've built a beta version over the last four months and it is ready to test!
I love Tildes, and I don't want to self-promote, so I am not going to drop the app name / website, but I am here with an ask. We want feedback! We want to make this the dream app for anyone who is serious about growing their (English) vocab. We want you in our beta test group.
The commitment I'm asking of our beta testers is a bit onerous. I want to hop on a zoom call with you while you use the app for an hour or so and have you tell me what you love and hate. I want to ask you a bunch of questions about what you want to see in your dream learning app. Then I want to give you the app for a month a two; hopefully you'll use it and learn a bunch of words; then I want to hop on a 20 minute call with you and get your hot take on the whole thing.
It is such an intense passion project for me; I want to make the app just rock-your-world-awesome. That's why I want to do live user interviews. (Which is a little out of the ordinary for sure.) And I can't do that without talking to real people who care about growing their vocab who are willing to hang out with me for an hour or two. :)
As a thanks for your help, when we go to the paid version, you'll get three months free, and a massive lifetime "friends and family" discount. But more than that, you'll really impact what we build next, and how we can make it better. While it's maybe a little idealistic, or might even sound silly to some, I feel like better vocab = better communication = better relationships. So I am all-in, fervently devoted, and hopeful that you'll come along for the ride and help me make it epic.
Who is it for? Studying for standardized tests? Oh yeah. This will help a lot. Want to raise the ceiling on what you can read. Let's go! Want to improve your English skills? This is for you. Love words. Yep! I'd love to meet you! Basically, if you love words, and/or have something coming up that requires that you know more words, I really hope you'll be part of our test!
More interesting stuff about vocabulary:
--Average high school graduate has a vocab size of 16,000 words
--Average college grad, 20,000 words
--Average PhD. 28,000 wordsTildes is a very smart and well read group, so I' bet the average vocab size around here is 25,000 to 35,000. Want to know your (approximate) vocab size. One of the best (easy and fast) tests is here:
https://preply.com/en/learn/english/test-your-vocab
(I have nothing to do with that site or company, and do not endorse them. It's just that their vocab size estimator is really well done.)Want to be a beta tester, or just talk more about vocab, shoot me a message!

I'm curious if there's anybody here who's like this. Either doing it without writing things down, or doing it minimally. I don't know why but I find it very difficult to do, and it stops me from actually learning/studying. I feel like it slows me down, significantly. It also feels like a chore. I feel like part of this may be because I'm in information security? Like, there's a lot of reading and researching going on, then immediate practicing and applying. Even when I have to take tests. I just read and listen or whatever else and that's it. Maybe in other fields, taking notes is a big thing, or maybe it's just me. I also have other interests, but yet still, I simply can't bring myself to write things down. I just prefer to absorb everything, in whatever pace I like, sometimes it's slow, sometimes it's fast. If I ever decide that I'm going to take notes while learning/studying, I'd stare at my notebook/software for a very long time. I'd sit with one chapter/slide for quite awhile. At the same time, I truly admire people who take notes and write stuff. I do wish I was like them sometimes. Is anybody out here the same? Even though I really want to hear from people who are similar, everyone else can join the discussion too. What do you do? How do you do it? What is your preference? Do you think there's a "better" way to do things? Could taking notes be "superior" to the opposite?

Hello Tildes,
I am currently taking DSA in college and struggling a lot with the math and algorithms. Recently had to solve Karatsuba questions and I don't even know what I wrote down on the paper. I have been trying to look for videos on this and only really came away with a vague understanding.
What I've noticed is that I struggle with solving the math part of the questions.
For example: "Describe a divide and conquer algorithm to compute the square
of an n-digit integer in O(n log3 5) time, by reducing to the squaring of five [n/3]-digit
integers"I have zero clue how I am supposed to understand the latter half of the question. It makes no sense to me beyond I am supposed to be multiplying squared numbers. How do I even begin to turn this into an algorithm? What is the solution even supposed to look like?
Needless to say, I've struggled with math my entire life and I've been trying for years to be decent with it, and I have nothing to show for it.
So, do you have any recommendations that could simplify the math needed for DSA? Videos are preferred but I will textbook recommendations as well.
Thank you, and have a good day!

Self-taught guitar players: How did you do it? What do you wish you could go back and do differently when you were learning?

I’ve been getting back into guitar playing and trying to have more focused practice when I play each day. I wouldn't call myself a "beginner", but I don't think I'm near the "intermediate" stage yet. I know chords and power chords and can transition between them pretty easily. I've been working on figuring out CAGED shapes, but still really struggle with playing scales and "solo-ing"...partly because (1) I have tried exploring music theory and "learning the notes on the fretboard", but it hasn't clicked for me yet, and (2) my fret fingers feel sluggish and don’t seem to move across the fretboard with the ease that I seem to have when switching chords.
That said, I’m feeling pretty discouraged right now. Looking for some “pick me ups”, so to speak. And wanting to learn to play a few songs all the way through so I can feel more confident in my ability to actually play a song. But I don’t really want to get hung up on a difficult “solo” or a bunch of individual fretting stuff yet.
As I thought about making this post, I figured it might be useful to also ask about some "beginner tips" on how to best stay motivated to stick with learning, practicing, and playing the guitar. If I'm going to keep this up, I want to really invest in it and stick with the guitar. Here are some additional questions/thoughts to hopefully trigger a discussion.
Fellow guitarists:
- What has helped you in the past?
- What helped you get over the "discouraging" first steps of guitar playing and keep at it?
- What were some of the first songs you were able to learn to play all the way through?
- How did you learn the notes on the fretboard?
- How did you learn to play different chords all around the neck?
- What would you say to your younger self to help encourage them to continue pushing through the sticking points of guitar?
- What was the "key" to getting guitar playing to "click" in your brain?
Looking forward to seeing what advice fellow players can offer! Everyone's musical journey is different, and I am interested in learning how you learned to get to where you are now!

Hi all,
I've been interested for a while in learning to play banjo. My first exposure to it was listening to bluegrass, but recently I have gotten very into Celtic and Irish music, and I think I would most enjoy learning to play by playing that style. Hence I am interested in Irish banjo, which I have come to understand is a bit different. I have a few questions that I was hoping someone here could answer. I don't play any other instruments and I'm interested in this just for fun.
-
My understanding is that the typical Irish banjo player plays a tenor banjo with 4 strings. However I see some variation between 17 and 19 frets. Does anyone have some insight into the difference here, and which might be preferred?
-
How hard would it be to learn other styles if I start with a 4 string? Is it like going from playing bass to guitar? Is 4 string typically seen as easier to pick up? I like Celtic music but not totally sure I want to be "locked in" to that. But then again, maybe that would help to be a bit more focused.
-
To get specific, I am thinking of buying this as a beginner banjo. I'd be surprised if so, but does anyone here have experience with this brand, or else have other recommendations?
Like I said, I am a total beginner in that I've never played any instrument. So on that note, if you think I'm asking the wrong types of questions, I'd want to know that too!

My whole life I have lived with the regret of not becoming proficient in a musical instrument. I grew up with a piano and acoustic guitar in my childhood home, and I actually took lessons for both but never committed to practicing or improving. As a result I grew up tinkering with both hit never learned how to read music or actually develop any fundamental techniques to play either.
I am an autodidact and have always felt that with the right resources, and a little discipline, I could at least learn enough to play a few songs on either instrument, and possibly with time become a sight reader.
To that end, I am curious, musicians of ~Tildes, what resources are the best to self-learn piano and guitar? Books, videos, apps, anything that you’ve used or know people have used and actually went from complete novice to reasonably proficient?
Thanks and happy new year!

Are you currently learning a new language? Are there any languages that are on your wishlist to learn?

I grew up semi-bilingual (English as my native language, Spanish spoken at least once a day at home), and went on to study Spanish as my language of choice in middle and high school. Despite this, I would still like to further my Spanish language skills/knowledge with some self-paced coursework, as the Spanish I grew up hearing in the house was much more colloquial and then the Spanish I studied in school was the "from Spain" Spanish, rather than the Central American Spanish my family spoke. I grew up being better able to understand more than what I could speak or write myself.
When I moved onto to college, I wanted to try studying a different language, so I chose French (bad idea; I could never really get the hang of it between the spelling challenges and the pronunciation being so different from the written word). I took one semester and passed just enough to get credit for the class but moved onto to German -- which was a little bit easier than French but more difficult than Spanish. Beginner classes in it were easy for me to learn, but I started to struggle when I got to upper-intermediate. Plus, I'm not always great at spelling in English, and French and German are not "speller-friendly" languages haha.
Now as I approach my midlife, I am thoroughly enjoying my ASL for Beginners course through my local community college. I find it incredibly intuitive whenever I learn new signs ("oh, that makes sense, cool" when I see a new sign). My mother-in-law has known and taught ASL (as well as SEE) for over 20 years so she is very helpful with me practicing and being able to correct any small mistakes I make. I don't know anyone who is Deaf, but have had a few friends growing up who used hearing aids (I don't think they knew ASL).
So what about you? Are you currently learning a new language? If so, what is it, how do you like it so far, and what led you to want to learn it? If not, are there any languages on your wishlist that you'd like to learn someday?
For me, I wanted to learn ASL as a way to connect more deeply with my MIL in our relationship, as well as have some level of ability to sign with those who are Deaf/deaf. I also wanted to learn it because I wanted an alternative way to communicate with my spouse if we are at a noisy event/party/etc. without having to shout to be heard.

In the dappled sunlit waters of Caribbean mangrove forests, tiny box jellyfish bob in and out of the shade. Box jellies are distinguished from true jellyfish in part by their complex visual system — the grape-size predators have 24 eyes. But like other jellyfish, they are brainless, controlling their cube-shaped bodies with a distributed network of neurons.

That network, it turns out, is more sophisticated than you might assume. On Friday, researchers published a report in the journal Current Biology indicating that the box jellyfish species Tripedalia cystophora have the ability to learn. Because box jellyfish diverged from our part of the animal kingdom long ago, understanding their cognitive abilities could help scientists trace the evolution of learning.
The tricky part about studying learning in box jellies was finding an everyday behavior that scientists could train the creatures to perform in the lab.
- Roots of mangroves
Anders Garm, a biologist at the University of Copenhagen and an author of the new paper, said his team decided to focus on a swift about-face that box jellies execute when they are about to hit a mangrove root. These roots rise through the water like black towers, while the water around them appears pale by comparison. But the contrast between the two can change from day to day, as silt clouds the water and makes it more difficult to tell how far away a root is. How do box jellies tell when they are getting too close?
“The hypothesis was, they need to learn this,” Garm said. “When they come back to these habitats, they have to learn, how is today’s water quality? How is the contrast changing today?”
- Setup
In the lab, researchers produced images of alternating dark and light stripes, representing the mangrove roots and water, and used them to line the insides of buckets about six inches wide. When the stripes were a stark black and white, representing optimum water clarity, box jellies never got close to the bucket walls. With less contrast between the stripes, however, box jellies immediately began to run into them. This was the scientists’ chance to see if they would learn.
After a handful of collisions, the box jellies changed their behavior. Less than eight minutes after arriving in the bucket, they were swimming 50% farther from the pattern on the walls, and they had nearly quadrupled the number of times they performed their about-face maneuver. They seemed to have made a connection between the stripes ahead of them and the sensation of collision.
- “It’s amazing to see how fast they learn,”
Going further, researchers removed visual neurons from the box jellyfish and studied them in a dish. The cells were shown striped images while receiving a small electrical pulse to represent collision. Within about five minutes, the cells started sending the signal that would cause a whole box jellyfish to turn around.
“It’s amazing to see how fast they learn,” said Jan Bielecki, a postdoctoral researcher at the Institute of Physiology at Kiel University in Germany, also an author of the paper.
Researchers who were not involved in the study called the results a significant step forward in understanding the origins of learning. “This is only the third time that associative learning has been convincingly demonstrated in cnidarians,” a group that includes sea anemones, hydras and jellyfish, said Ken Cheng, a professor at Macquarie University in Sydney, Australia, who studies the animals. “And this is the coolest demonstration, replete with physiological data.”
The results also suggest that box jellyfish possess some level of short-term memory, because they can change their behavior based on past experience, said Michael Abrams, a postdoctoral researcher at the University of California, Berkeley, who studies the neuroscience of jellyfish sleep. He wonders how long the box jellies remember what they’ve learned. If they are taken out of the tank for an hour and then returned to it, do they have to learn what to do all over again?
Future work
In future work, researchers hope to identify which specific cells control the box jellyfish’s ability to learn from experience. Garm and his colleagues are curious about the molecular changes that happen in these cells as the animals incorporate new information into their behavior.
They wonder, too, whether the capacity to learn is universal among nerve cells, regardless of whether they are part of a brain. It might explain their peculiar persistence in the tree of life.
“There are organ systems popping up and going away all the time,” Garm said. “But nervous systems — once they are there, they very rarely go away again.”
Perhaps the ability to learn is one reason they are still here.

This book uses cartoon mascots assigned to three areas of music training on the keyboard: dexterity skills, reading/writing/listening, and repertoire performance.
Each mascot starts off as a cute lil’ dude and evolves into huge powerful creatures as the child “levels up.” My ultimate vision is a book or book series that utilizes the mascots in figurine form for prize-incentives and mascot videos to offer help and guidance for individual activities.
The first prototype will only feature the books, and I expect to finish it in the next 1-2 months.
I was hoping to get a list of potentially interested parties that would beta-test the book without cost in exchange for feedback/testimonial.
If you’re interested, please send a message through my website— https://alexgoodhart.com/lessons (you won’t see any mention of the book there, but can send your contact info through the inquiry form).
If you’ve any thoughts to share here I’m all ears! Thank you — Alex

Parenting anxieties: Contexualising WW2 for a nine year old

OK, so I have a very nerdy, mildly ADHD 9 year old boy who has been fascinated with WW2 for ages. All this started with him getting obsessed with the Titanic when he was about 4, which then led us to look at some old Nat Geo magazines about Robert Ballard's oceanographic expeditions which then led him to get fascinated with the German battleship Bismarck and Operation Rheinubung. The drama of big gun battleships got him in the feels and in the five years since then he has been deeply into naval stuff, particularly WW2 naval combat ever since. Musically this got him into Sabaton and their WW1/2 related metal songs. He actually sat down and watched the 1960s black and white Sink the Bismarck on YouTube, along with stuff like Midway (the version from a few years back). He thinks aircraft carriers are cool and ate up both Top Gun movies and is now getting into submarines (loved The Hunt for Red October) but wistfully repeatedly tries to reason me into agreeing that navies should have stuck with big gun battleships.
However, this has manifested as a deep fascination with Germany in general- he knows the basics about fascism, the Holocaust and Wehrmacht atrocities (but still can't quite get why it happened) but to a small boy I understand the OMG WUNDERWAFFEN attraction. Coincidentally his best friend is an ethnically German girl which further gets him a bit confused because he can't quite grok the difference between "my friend is German, I think German engineering is cool" and "but we still condemn fascism".
To be clear- he understands why racism and prejudice are wrong. As an ethnic minority in our country I suspect he'll come into contact with racial prejudice sooner rather than later so hopefully life experience will lead him away from the alt-right bits of history nerdery.We're in Singapore, which means there's very little consciousness of the Holocaust in public education- our history syllabus (fairly enough) deals with the Pacific War and its effects on postwar decolonisation when it touches on WW2 whereas the European theatre is just vague background.
I don't know where I'm going with this, really- I like that my son is a history buff, and I don't want to cut him off from intellectual interests he's passionate about but on the other hand I'm wondering how I can let him enjoy this while contextualising it from a progressive perspective.

Duolingo alternatives for learning Ukrainian

Hello! Привіт! Pryvit!
I started learning Ukrainian on Duolingo in February 2022 following Russia's attacks. It was my first time attempting to learn a language for 10+ years and it just clicked. I grew to love the language, became entranced with the culture, and had desires to keep learning. Prior to Duolingo's redesign, I had a year+ streak and made it fairly far in the course.
The redesign has absolutely killed that passion. Maybe it's just the Ukrainian course, but it felt like I was going in circles and not really progressing as I once had. I've shelved my learning for a few months, but I really desire an alternative to Duolingo. Unfortunately, there's not many options that offer Ukrainian and I want to ensure I am learning the language as intended. I've read into how Russian influences have attempted to modify the language and I desire to learn the form that Ukrainian's would use.
I'm not quite at a level to learn from books or more static resources, and would prefer the interactivity of an app to help get me to that comfort level again. I've tried Pimsleur and wasn't as much of a fan of their format that reminded me of language tapes. One of the things I enjoyed with Duolingo was the verbal parts of it that helped with my pronunciation, and Pimsleur didn't appear to offer that.
Any recommendations would be greatly appreciated! I have seen old posts referring to a SubStack and other resources, but at this time I need a refresher before I feel comfortable diving into those. I would love to incorporate learning a little bit of Ukrainian everyday again! Слава Україні!

I've recently started teaching myself piano again after a long hiatus. I started by picking back up a piece I half-remembered from years ago -- Chopin's Nocturne in E Minor, Op. 72 No. 1 -- and about the first half of it feels right for my current skill level (basically everything up until all the RH 16th note runs start). While that's going great so far, I no longer have a piano teacher to recommend me new pieces beyond just this one, and I'm not entirely sure where to look myself to find things that are interesting without being too technically challenging. Would love a few recommendations from any pianists on here, either for specific pieces to look into and/or for good ways to find suitable pieces more broadly!

I think many of us are students, or just like self-learning some topics for themselves, perhaps their work requires studying — I think it might be interesting to collect a few tips we have experience with on how to do it efficiently.
I would start with probably one of the best tools in this category that I think are still underutilized by many: spaced-repetition software. Perhaps more people might be familiar with the concept from language learning with word cards, but the base idea is that reinforcing some knowledge at increasing intervals will effectively make you remember it ’forever’. A final selling point on this topic: it only requires 10 minutes out of your entire life to remember a fact for basically forever with instant recall - that’s a very good use of one’s time in my opinion. For more information on it here is a great article.
(It’s talking about Anki, a notable spaced repetition program that is free and open-source (the ios client is paid though, as this is the only income source of the maintainer, but you could just use the web interface as well. Not affiliated))20 votes -
