I worked for years as a sysadmin grepping through history because I'm just learning this from you. Thanks!

I had a coworker who was having some issues. I chuckled when he had an alias for history | grep when I was checking out his env

Is that why his Mercurial wasn’t working?

They go to "articles/...." instead of "/articles/...." e.g. https://quanticdev.com/articles/most-valuable-thing-to-learn... should be instead https://quanticdev.com/articles/raspberry-pi-guide-for-devel...

thanks just fixed them. accidentally used relative path instead of absolute.

Ah yes, I'm sure we've all been there. :-)

Check out something called "Core Transformation Process", it's a simple algorithm, you can learn it in an hour (although I think the full training is ~3 days, but that includes other stuff as well), and it has very profound effects.

Watch bon appetit on youtube for an hour. It's fun and you may find yourself thinking about cooking more for fun rather than a chore afterwards.

Whether cooking is fun or a chore is, I think, directly related to how much stress the rest of your life is causing you. If you’re extremely busy holding down multiple jobs just to pay the bills and feed your kids, then it’s hard not to see cooking as a chore. A person in such a situation is going to get very impatient trying to watch most cooking videos which tend to waste a lot of time talking about things unrelate…

Of course, that's true of a lot of things. Many things are fun when you're doing them because you want to and have the time but are chores when you have to do them even though there are other demands on your time or you're just not in the mood.

I'm definitely like that with cooking. It's a hobby of mine but there are nights when I just need something to eat and get on with other things.

Vim. I think it can be in the list as well. It takes a long time to properly learn. But one hours is defiantly enough to get to know the main Vim bindings, to be as productive as in other editors. In the end it makes you super productive.

Serious question: I keep seeing Vim thrown up and down like it's the holy grail. I've been using VS Code for two years maybe now, and I don't see how Vim could help me be a better/more productive coder. What am I missing?

I’m saying a positive ROI is not the same thing as compound interest. An asset that rises in value like $SPY is not in of itself an example of compound interest.

This feels like a semantics back and forth. Call it compound growth then. It's the same concept. This applies to all yielding assets. You can call it divs / buybacks for stocks and interest for bonds, but it's the same thing / effect.

Not even vaguely.

Compounded interest is reliable, even boring. You know exactly what you'll have at any moment in time.

Your ten-year index returns are reasonably reliable, historically. But your 2007-2009 returns aren't your 2016-2018 returns, at all.

They're different concepts and deserve to be conceptualized differently, especially in the modern era, where interest rates on Treasure are lower than inflation.

I also think the reddit personal finance crowd is way too focused on how to invest their existing money when almost everyone would be better off figuring out how to make more money from their day job than worrying about whether they can make 4% here vs 5% there from their existing savings. Perhaps less true if you have a large savings of over $1M already, but otherwise no.

Or cutting extraneous expenses. It's cliche, but really, making your own coffee and packing lunch can save $20-25 a day. That adds up fast.

This is true, but it's also a good thing to go to lunch or have coffee with other people. You'll get personal enjoyment out of it, and if you are talking shop, the relationship you build could offset the savings of packing your own lunch.

For example it's common that you will regularly have lunch with a work colleague, and then later they will recruit you to work at another company. Or they will give you insight on how to get support behind your project at your current company.

And for unfathomable (haha, well, is it really though?) reason retirement accounts are set up to mostly benefit people with very high wages whose employers (gotta have an employer, too, or arrange things so you're your own employer—man is this dumb, it's as if it's set up to disadvantage the poor and middle class) also provide a high match rate. Meanwhile most folks are lucky to get a 1 or 2% match, leaving them way…

There are caps for contributing to tax-advantaged savings and pension accounts in the UK too. I wouldn't say that that 'disadvantages the poor and middle class'. It's the other way around - it disadvantages the upper-middle and wealthy because they hit the limit and have to find other ways to accumulate wealth.

The way 401k retirement accounts are set up in the US, you can't get anywhere near the contribution limit on your own, you have to have huge amounts of employer contribution, beyond simple matching, even. It's like (cough) it's designed to mainly benefit top-tier professional class folks and non-owning-class upper managers while chaining people to traditional employment or complex personal tax arrangements. The other tax-advantaged account, the IRA, has a much lower total contribution cap.

[EDIT] to be clear it's not an absolute disadvantage to the poor and middle class versus having no such system, it's just that the way it's structured the overwhelming bulk of the tax savings goes to people who are already very well off, and those "beneath" them cannot possibly, no matter how frugal or responsible or fairly-well (but not excellently) compensated, hope to touch the level of benefit the very-well-off derive from 401k accounts. It's impossible, thanks to the way they're structured.

[EDIT EDIT] they're actually ideal for rich people who want to transfer ~$56k/yr to each of their kids (about $1.5m over 30 years), tax-free. I'd bet there's a further scheme one can work out to direct the investment of the fund such that the personal benefit is much greater than that, even (oh, kid of mine, you want to start a business? Funny, our 401k fund also "wants" to invest in it!). How? Employ them at one of your C or S corps (LLC or partnership won't let you get anywhere near the contribution limit, because... reasons? I dunno, it's a really dumb system if [cough] you're trying to make it broadly available to and useful for normal people) in one of the many positions near the top that're well-compensated but are so easy that lots of folks (stalk some from-money C-suite or "investor" types on Linkedin to see what I mean) seem to find time to hold one of them and also a few other "jobs" at the same time, so it won't look out-of-the-ordinary.

Not USA, but if you have a KBC in your country (a Belgian bank, but you'll find them in other EU countries) they offer a quite easy way to start investing in index funds. Essentially, each time you use your debit card, they round up the amount you owe the shop, and put that in a special account. For each 10 euro in that account - they invest it. So for example, let's say I go to the shops and pay 9.30 for groceries.…

I wonder if this can have a detrimental effect for compulsive buyers: “Oh I shouldn’t buy this widget but a chunk of it will go towards my retirement anyway!”

Mh, that seems like a weak excuse because at most 99 cents would get "saved"

If you like this, you'll also like pushd/popd. Example: $ cd ~/src/app/foo/bar/baz $ pushd /etc/qux/quux/quuz/corge/grault/garply/waldo $ popd $ pwd /home/you/src/app/foo/bar/baz It's a stack of directories. You pushd the current directory on to the stack and cd to a new directory all in a single command, then you popd back to the previous directory (i.e., the one on the top of the stack). It's useful if you're jumpi…

It's not as robust as pushd/popd, and it may vary from shell to shell, but at least in bash you can also use "cd -" to change to the previous directory.

pro tip : you can also do the same with git : "git checkout -" will bring you to the previous commit you were on
