First, let me just say that I'm tech savvy, but I'm self taught for the most part. I never studied cybersecurity or network security. I know the basics, but not the nitty-gritty.

I used to host my own Anytype Server (note taking app) on my raspberry pi. To do this, the documentation says that I need to open two ports, one TCP and another UDP. So that's what I did, and had it set up this way for a while now.

Yesterday though, my raspberry's microSD died. So while I wait for the new one to arrive, I'm taking the chance to review my home network settings.

I closed off a third port that I had for my synology server (for the OpenVPN). I am now using Wireguard (with Tailscale) which doesn't require opening ports. And since my raspberry is offline, I also turned off the other two ports (as of now, I have none opened)

So here's the thing: I remember from my searching that a lot of people are strongly averse to opening ports. Iirc, the basic idea is that if a bad actor knows my home IP and which ports are open, they can enter. So, in theory, a hacker could potentially infiltrate my raspberry pi - and from there potentially wreak havoc in my other devices.

So my questions are:
1- Is it really like that? Could a hacker gain unlimited access to my raspberry via an opened port?
2- If yes, is there something that I can do to strengthen my raspberry pi security?
3- Am I being overly paranoid by worrying about this, even if it’s theoretically possible?

Does anyone have any idea on how different online translation "services" actually rank now? I was thinking about this today (after I saw the TranslateGemma announcement) and realized that I had not really updated my view on translation apps/services in quite a while.

There is Google Translate, Apple Translate, Kagi Translate, DeepL, etc., but I have no idea how these would rank, especially if it comes to different use-cases.

Previously Tildes have had a few discussions on good quality Youtube channels one, two, but I couldn’t find a recent discussion.
I would be interested in peoples recommendations!
Personally I would like to get recommendations for intermediate/harder science or engineering videos. Most are too basic, or very dry lecture based. I know a few good ones like:

• 3blue1brown
• Smarter every day
• Looking Glass Universe

But I would like to know other people’s favourites (including non science ones)!

Do you ever get that FOMO feeling that all your friends and family use insert-social-media-app name? That you are the outcast fighting the uphill battle of avoiding those horrible apps and the forced advertising they shove into your eyeballs every minute? Well, I did, and decided to give Instagram a shot to see how things are.

Well, you will not be surprised to hear that it is as awful as you probably imagine. It did not get better since I left maybe 5 years ago. It got worse. The only way it's better is, funny enough, the technical creative element. You can do a lot more. The video editor for the reels is surprisingly good and easy to use. Far better than iMovie (on iOS). Aaaand that's about it! Everything else is worse. More ads, more content that I just don't care about, etc.

An important realization about the content itself, reels and stories. We all know it's one-sided, that you often see only one side of a person. That's not new. What I did feel this time around is that, coming from zero FB/Insta/X/TikTok for over 5 years, being exposed to this kind of content suddenly starts inserting a vast amount of self-doubt in one's daily life. I'll use a mild example: fitness! I am an active person, I exercise more or less regularly, I walk my dogs, I do some outdoor activities, light sports, etc. Well, I start seeing content on this topic, and initially think "Oh, this guy has some good tips!" But then I see 10 other content creators with 10 different ideas of what is "right" and I end up so confused, doubting whether I am doing things right. Now take this example and think about other topics: mental health is a big one! All of a sudden I see these ads and accounts targeting me and making me feel like I'm not happy enough, or not investing enough time in whatever thing they are selling. I have a pretty strong radar for this stuff, I am conscious of how this works and on alert. It didn't get to me because I spotted the trend early. But I am wondering how many people are aware of this? Here on Tildes, probably most. Outside, in the wild? People glued to FB/Insta/X all the time? Probably very few.

A family member is constantly on Instagram, consuming this "mental health" content. When you get 10 different types of advice, how are you to know what to prioritize, what actually works. I think it does more harm than good. Zero advice may be preferable, in a way that lets your own psyche figure it out versus being bombarded by these "helpful" content creators.

I did go back to Instagram primarily to get back in touch with friends and family who I lost track of, or who use Instagram as a way of creative expression. Sadly, I realized few people actually do that, and most are just lurking, or watching reels and sharing reels. This gets old fast. Yes, some reels are funny and it's fun to laugh with the person next to you. But they are also addictive and I found myself defaulting to scrolling over other activities that are far healthier for the brain and for the heart.

What do you think? Am I way off the mark here? Did you have a similar experience with these platforms?

I've been using Google Keep (check boxes mode) for my work and personal to-do lists for a while now, and it's almost perfect for my use case. I love the simplicity and lack of options gumming up my process, and specifically I like the UI of having nested subtasks that all move with their head task when you reorder the top level tasks. That is to say, when you drag a headline task, all of its subtasks "roll up" inside it and "unfurl" when you drop the task into its new location. The fact that it syncs across devices is also really great, but not necessarily a deal breaker.

What is becoming a deal breaker is that you can only have 2 levels: top level or nested. I want more nesting levels, but with the simple touch-and-drag UI to which I've become accustomed.

Have any of you heard of/used an app such as I've described? I have issues using bigger, more fleshed-out apps because all the features distract my goblin brain, and the friction of having to use various touch menus or the keyboard on my phone to adjust indent levels keeps me from getting crap done.

Thanks in advance!

Edit: for now, I have settled on Workflowy. It seems to offer the most similar functionality with an acceptable number of interactions to do the things I want to do. Thank you to everyone who offered their experience!

I need a German phone number, so I need a German SIM.

My preference would be a prepaid year because it’s a bit cheaper. Also, I have a physical sim slot and would rather use a physical sim than an eSIM.

Many apps (Mein O2, MeinMagenta for cell services and most of the local transit apps) are region locked. I can’t currently change my Apple ID to Germany and can’t make a new Apple ID for Germany without a German phone number.

Any hot takes on Telekom, Vodafone, O2, etc. or recommendations on getting a physical SIM card?

Note: The Aldi closest to me only had eSIM today or thought they only had eSIM.

Edit: I actually need a phone number for things, e.g. kita being able to call me if one of my kids get sick at daycare.

With CES 2026 coming to a close, I figured that like last year, I should make a thread to see what people are excited (or not excited) for.

I honestly wasn't that excited (see recent state of US economy) but I want to your thoughts!

I didn't post in the thread as I didn't have much to add, the top post by @Oxalis basically sums up my thoughts

Nice to see them be honest about how this isn't really panning out. Everyone wants AI except the consumer.
