Make your own. Your mental health loves you when you come up with stuff. Humanity has generated so much content and none of us have the lifetime to consume it all, but that shouldn't stop you from making your own any chance you get.

Make music - you don't need an instrument if you can whistle. Make stories - just say them to a recorder or your kids or write them down. Make food experiments - nothing will please your taste-buds more than listening to them and iterating on ways to get better. Make your own apps or experiences - with AI or by hand, your ideas may be surprising and worthwhile. Knit or make your own clothes, toys, wearable tech. Design your own 3D objects and maybe print them or animate them.

We know that workouts lead to endorphins for the body, but the brain version of that is not only enjoyable but also can be scaled to be enjoyed by other humans too sometimes. Don't go through life without trying your own things.

during the pandemic I was exposed to the "Today I learned" comment in slack, and I really liked it because it was usually something interesting (or comical, or painful) and relevant, and also helped me connect with my coworkers. I highly recommend sharing both here and in your group/team message channel random & interesting things you learned today with the #TIL tag.

Today, I am revising Portuguese grammar and so I've mostly been exploring the things I can remember well and those that I can't. Portuguese has a lot of verb forms that I need to get right. But it also has really interesting constructions like "ir ter com" which literally means "to go to have with" but is an idiomatic way of saying "to meet up" (with someone) and I keep remembering and forgetting it.

What do you use to revise this? Did you download or make an Anki deck?

Paper. I have revision sheets on paper.

In 2026 I started writing letters. I mean, docs on my computer that will end up printed in physical form, then handed to someone, or shipped to someone in an envelope with a stamp.

I feel I will do more and more of this, this year, as a little experiment. I will most likely experiment with different types of papers, etc.

What brand/make of battery is that? I'm tentatively interested in home battery storage, but definitely not interested in shit that requires an app, an internet connection, and shitty saas spyware...

MARSTEK VENUS E 5.12kWh. Got it in August 25 for 1050,00 EUR. It is awesome how open it is designed, I was able to activate and automate it without adding it to my local network (wifi) or using the Marstek App even once. I wrote a blog post here [1]. [1]: https://du.nkel.dev/blog/2026-01-11_marstek-battery-homeassi...

5 kWh for 1k€! Wow! Thanks for sharing

Edit: and thanks for the writeup. This is exactly what I was looking for

It wasn't literally today, but about 2 days ago I discovered the -H (and --host) arguments to systemctl. These allow you to pass a hostname of a remote server, so you can use systemctl to manage systemd services on remote machines. It layers over ssh, so the cleanest way to do it is to have passwordless ssh with certificates set up to the remote host. If you do, running systemctl commands remotely is totally seamless…

What's the advantage to systemctl --host foo status httpd.service vs ssh -t foo systemctl status httpd.service ?

> What's the advantage to ...

For me personally, I'd say "not much". I'm used to using the latter form, and it's fine. But I will say that now that I know about this, I see using it in scenarios where I'm running a lot of systemctl commands over and over again in close proximity and have the "muscle memory" of typing "systemctl" more in mind.

For example, when working with a new service that isn't quite working right yet, and doing many iterations of:

    $> systemctl start something.service
    $> systemctl status something.service
    $> journalctl -xeu something.service
    $> emacs whatever
    $> systemctl start something.service
    $> systemctl status something.service
    lather, rinse, repeat
Especially if I'm testing on my laptop AND a remote deployment, I think it's easier from a cognitive viewpoint to always "think systemctl" instead of having to "think systemctl" sometimes and "think ssh systemctl" in others.

To be fair though, it's all a pretty minor point. But I do think it's cool that systemctl has that option. shrug

On a recent trip to Costa Rica, I discovered "Rice and Beans," which is not Gallo Pinto, but a Caribbean-influenced dish made principally of white rice, red kidney beans, coconut milk, and thyme. The dish name is in quotes because it's really the English words "Rice and Beans." It's marvelous, and I couldn't wait to try making it myself at home. Unfortunately, so far, it's been a mushy flavorless mess. I'll try a thi…

I really miss gallo pinto. I went to Costa Rica in 2009, and since then, nothing has been the same (in NYC). It's mind-boggling that such a simple recipe can be so good in CR but so bad over here! I hear there are some Costa Rican restaurants in Paterson, NJ, but I haven't had the chance to check yet.

I also have fond memories of gallo pinto in Costa Rica from 1997 but when I describe it to family they just look at me blankly in mild disgust. Would love to know what the secret sauce is.

My home office gets up to about 1500ppm of CO2 by the end of the workday, which explains a lot about why I often feel exhausted after the end of a long, uninterrupted session in there (especially when I’m on back to back zoom calls). I now have several plants in there that are supposed to be especially good at sucking up CO2, and my sensor reports that the current level is slightly below atmospheric ambient CO2 level…

My issue is that, during winters, the bedroom's CO2 raises to the 2000ppm levels. But I keep all doors open in this (small) apartment and not much changed. It's too cold to keep windows open like we do in the summer and it's nighttime so plants won't help.
