I'm also a recovering social media addict, it was a slow and painstaking transition but the benefits in terms of attention, concentration and attitude have been profound. The main metric for me was going from almost 5 hours a day of phone time 2-3 years ago, to about 1 hour today. Of course the socials still snuck in on other devices but that was the main thing which killed the poison at its root and then eventually all the offshoots withered.

The apps condition you to come back through a feedback loop. Once I broke the feedback loop enough times the whole idea of going into one of these apps or sites and watching my life disappear into it started to feel revolting, like I just knew it was going to make my day worse not better, then the hold was gone.

The next battle I see on my horizon is that I sometimes watch 20-30 minutes of YouTube subscriptions in the morning with my coffee. There's some good content, but sooner or later Google's going to try and kill my ad blocker and probably look for new ways to creep that time up into hours instead of minutes. I know it's coming and I'm ready to die on this hill rather than lose my morning. I will do absolutely anything to continue blocking ads, up to and including saying goodbye to YouTube, to Google, to a web browser, putting only TUI interfaces on my TV, anything.

My favorite small act of defiance this year was purchasing a $120 deluxe hardcover edition of the Lord of the Rings trilogy - that's a great work I enjoy enough that I'm happy to read it many times over the course of my life, it improves my attention span instead of worsening it, and it won't show me a single ad ever. So I figured in terms of recreation, it's one of the best investments I could make. Perhaps several of such omnibuses on a shelf next to a comfortable armchair is the best defense against Big Tech.

On Coursera, I did Andrew Ng’s machine learning course and Dan Boneh’s cryptography course and both were excellent. Time well spent IMHO.

The next thing I want to take is a WinDbg course. Udemy has one that looks pretty good. I should probably also find a modern assembly language course…

The kana are usually written in a table where each row is a vowel and each column is a consonant, like on Wikipedia[1]. Most columns of the table have five characters, each representing the same consonant combined with one of the vowels. For example: か/き/く/け/こ ka/ki/ku/ke/ko, ま/み/む/め/も ma/mi/mu/me/mo. Some columns have "missing" sounds (や/ゆ/よ ya/yu/yo); but what's important for our purposes is that some columns have irregular sounds: さ/し/す/せ/そ sa/shi/su/se/so and た/ち/つ/て/と ta/chi/tsu/te/to. There are no si, ti, or tu sounds in standard Japanese; they have shi, chi, and tsu instead.

Using diacritic markings gets you more consonants. Most of these are made by adding a couple tick marks to the corner of the character, which makes the consonant voiced instead of unvoiced. For example: か ka -> が ga, と to -> ど do, ひ hi -> び bi. But the irregular sounds stay irregular: し shi -> じ ji instead of zi, ち chi -> ぢ ji (again) instead of di, and つ tsu -> づ zu instead of du. (す su -> ず zu gives the same sound but in a regular way.)

You can also combine i-vowel characters with y-consonant characters to get sounds with consonant clusters: き ki + や ya = きゃ kya, み mi + よ yo = みょ myo, etc. The irregular sounds remain irregular: し shi + ゆ yu = しゅ shu (instead of syu), ち chi + や ya = ちゃ cha (instead of tya), じ ji + よ yo = じょ jo (instead of zyo). There's a Reddit post with a nice table showing all the available sounds[2].

Now the problem for romanization is this: Should the romanization reflect the irregular sounds in the spoken language? Or should it reflect the regular groupings of the kana characters? づ and ず might both be pronounced "zu", but they come from different linguistic origins, just as "bear" and "bare" do in English. The Hepburn system uses spellings that match the sounds, while the current standard (Kunrei-shiki) uses spellings that match the kana grouping: し si (instead of shi), ち ti (instead of chi), じ zi (instead of ji), つ tu (instead of tsu), じょ syo (instead of sho), etc.

The Hepburn system tells you how to pronounce the word[3] at the cost of being a lossy encoding. For anyone familiar with the Latin alphabet, that's almost always the better choice, and it's nearly universal in the Western world. Kunrei-shiki does better reflect the underlying structure of the Japanese language and its native writing system, which is probably why the Japanese government preferred it. But anyone who wants to learn the language is going to learn the kana almost immediately (it's just a few hours with flash cards), so IMHO that's pretty small advantage.

I deliberately didn't talk about long vowels, glottal stops, the differences between hiragana and katakana, different pronunciations of ん (n), or how to handle ん (n) followed by a vowel, but if you're curious about Japanese romanization those topics may also be of interest to you. I can try to explain more if anyone's curious.

[3] Most of the consonants are the same as English or close enough and are trivial to write in the Latin alphabet. The big exception is ら/り/る/れ/ろ, normally written ra/ri/ru/re/ro but it's not really the English r sound. See: https://en.wikipedia.org/wiki/Voiced_dental_and_alveolar_tap...

I have Real Real Japan on my YouTube algorithm. So, I’m a bit of an expert on this topic…
