Jack Bogle did not advocate for adding international equities to a portfolio as a means of diversification. [1] [1] https://www.morningstar.com/articles/885739/why-jack-bogle-d...

The reasons in the link are fairly ridiculous

Please explain. I found the arguments quite reasonable and presented in a non-dogmatic way.

FYI, "hanaseimasen" is not a correct negative of "hanasu", it should be "hanashimasen". Also an easy way to say you don't understand anything is "wakaranai".

they weren't wrong. hanasemasen = can't speak hanashimasen = don't speak It's arguably more proper to say "nihongo ga hanasemasen" (I can't speak Japanese) than "nihongo wo hanashimasen" (I don't speak Japanese). The first is a statement of my personal abilities. The second could easily be a statement of my attitude. "nihongo ga hanasemasu kedo nihongo o hanshimasen" (I can speak Japanese but I don't speak Japanese)…

Wakaremasen would imply that you are incapable of or forbidden from ever understanding. It would be very strange.

I've honestly never heard anyone use ga before hanaseru. It's always been wo that I've heard.

Regular expressions fall into this category. While they might take longer to master, you should know the basics after an hour. I've been surprised at how often people convert long lists line-by-line. You can sometimes take what was a multiple-hour task and complete it with a handful of cryptic characters.

This always helps me in learning and debugging regex: https://regex101.com/

Well, the original wording was "hanasei masen" and I assumed the OP wouldn't know about the potential form at their current level. Potential form when talking about knowing the language doesn't sound right to me, but I can find example sentences using both potential and normal form. In natural language I think normal form would be used. Potential form of "wakaru" is "wakareru" which happens to be a verb with a completely different meaning "to diverge/separate/divide", so I don't think anyone uses it and it makes little sense anyway.

There's a growing realization that you can completely side-step the need for Single-Page App frameworks like React using websockets and the morphdom library. Projects like StimulusReflex (Rails) and LiveView (Phoenix) allow developers to build complex, reactive modern apps faster and easier by rejecting the need to even have client state. https://github.com/hopsoft/stimulus_reflex https://github.com/phoenixframework/…

Seems like cool stuff. Unfortunately, both of the StimulusReflex demos (Heroku apps) are giving errors right now. Maybe somebody hit a quota!

Quota was hit. Temporary: https://expo-pjf.herokuapp.com/

Half of Cyrillic is learned by the average HN reader if you tell them to think Greek rather than Latin. "P" is an "r" sound (rho), "П" is a "p" (pi), etc.

I always wondered why in English the constant and the letter π pronounced as /paɪ/ when the Greek letter is obviously /pi/. It really grinds my gears, there's no pie in π! Does Enlgish routinely localize foreign alphabet names? If so, it's bad practice. I believe no one in the world learns English alphabet pronouncing it arbitrary, and not as /ˈeɪ/ /ˈbiː/ /ˈsiː/.

Just a wild guess, but perhaps it's part of a vowel shift either in modern Greek, or modern English.

I know UK (bee-ta) and USA (bay-ta) pronounce Beta differently but am slightly ashamed to say I don't know how modern Greeks pronounce it. I understand it's derived from Hebrew's Beth, though?

Language is a constant curiosity.

If you've been married for a while, learn who your spouse is now . (I mean in a good way, by taking an hour to rediscover what his/her hopes and dreams are, what interests they've gained / lost, etc.) He/she is probably a pretty different person than the one you married. It's easy to overlook that.

The implication being that you just don't communicate between the time you first met and now?

I made similar functionality for Django a few years ago called Sniper. You write all your dom modification code as an Ajax request handler. In his handler you yield out a sequence of dom modification objects and sniper handles the rest. I couldn’t understand why this wasn’t a more popular approach.

The combination of websockets and morphdom vs Ajax polling and DOM updates is a major leap forward. Check it out!

Skills are gained through practice. To get good at non-trivial skills requires more than an hour. Knowledge is gained through insights. While a full understanding and implications of an insight can take a lifetime, an insight can be triggered in under an hour. Now which insights are most valuable? That is always going to be personal and relative. But one of the insights that touches all people and is almost universal…

Great suggestion. Also, might I recommend The Bitcoin Standard by Saifedean Ammous. Half the book is about money in general, not just Bitcoin. Very well written.
