@simsa04 Since your nephew already uses #Scratch, you could start here: https://projects.raspberrypi.org/en/projects/getting-started-scratch ... but I think he'll need a monitor first.
There are ways to set the Pi up "headless" and then use VNC to export a graphical desktop over a network, but I think most are pretty fiddly and prone to network DHCP changes that require unwanted effort to make it work again. Even so, if you wish to try this with your nephew, see https://learn.sparkfun.com/tutorials/headless-raspberry-pi-setup
Both the RasPi 3 and the 4 have #Wi-Fi and #Ethernet on the model B versions, which are most common. So they can join a home network and even be used to create a hotspot for other computers and devices. ( See https://learn.sparkfun.com/tutorials/setting-up-a-raspberry-pi-3-as-an-access-point/all )
Here are some others, but most seem to need more parts.

* Top 15 Raspberry Pi Project Ideas for Beginners https://www.youtube.com/watch?v=4T4N_lHo7P4 This is very general and probably not very useful right now.
* Setup to Project in 20 minutes https://www.youtube.com/watch?v=B_8ZcPeaxcc This one says it covers how to "remotely control Raspberry pi with windows or mac", so that might be good.

This school district in southern #NJ cancelled classes for three days last week, citing "Internet access" and "unauthorized third party". They didn't say whether there was a breach, or malware / ransomware, or even someone cracked their #Wi-Fi. I suspect that they'll continue to be closed-mouthed about what happened.

You've probably already seen this: https://ubuntuforums.org/archive/index.php/t-2459146.html [ubuntuforums org] (Suggested fix for the #Wi-Fi issue.)
The other issue is that modern Web applications bloat up memory use. I'm not even sure that 8GB will be enough.
Several years ago, I had a desktop machine with 4GB of RAM. If I opened Chrome with around 8 #JavaScrippled tabs, it could freeze my X11 session or even force reboot the computer in about 8 hours. Even though I'm sure Chrome and Chromium have improved, they are probably still really heavy on RAM usage.
I didn't look at the price / MSRP, but as long as you're sure that OpenSuSE will install and that 8GB will meet your needs, you're probably not going to find anything that is clearly better unless you're almost willing to double the price. I'd say go for it.

After almost two months of work, I found a GNU+Linux installer that would work on the new laptop. I'm currently replacing a recalcitrant and stubbornly anti-user #Win10 OS with #Devuan. Afterward, I'll figure out whether I'll need a #Wi-Fi dongle.

> Google Wi-Fi Provisioner won't work unless you enable Play Services
> Samsung Location SDK won't work unless you enable Play Services
I might believe that if #Wi-Fi wasn't working all the time I have had this phone. As for #location, that is turned off anyway. If there is any legitimate purpose for which the phone needs its location, tower triangulation can help a lot.
It makes me wonder what is so important about Play Services. What extra data collection or owner / user monitoring is embedded that #Android itself lacks?
-
Something about #NYC causes mobile devices to discharge more rapidly. I suspect much of it is related to #cellular and #Wi-Fi network coverage between tall buildings. But I noticed a milder version outside New York City, where I've been working the past few days.

The time you win without knowing how. Someone from a remote location was saying she had no ability to connect to a #Wi-Fi network, so she came to our location. As soon as she turned her laptop on, the wireless card activated.
She had spent hours on the phone with the national support line over the last few days. It turns out that we have a branch office with IT about 30 minutes commute time from where she works (a lot closer and faster than coming here).
Since I did not get to troubleshoot, we don't know why it was not working before.
Notified IT at that field office to expect a visit.

Assuming they can get #FCC approval, the next iteration should support putting 'Device A' behind the GL-AR750S with the others. The router itself should be capable of connecting to another #Wi-Fi and allowing a device on the network to do the public Wi-Fi's login routine.

Installing #DietPi on a Raspberry Pi Zero W.
I dislike some of their defaults already:
1. Expects an Ethernet connection. To autostart Wi-Fi, you have to edit a couple of files (one to enable #Wi-Fi and disable #Ethernet, one to enter your Wi-Fi logon information). It should accept either connection by default and use a "wifi-config" program to set up the connection.
2. Defaults to hostname 'dietpi' instead of having you name your device as part of setup.
3. Apparently, 'root' and 'dietpi' users exist with same password ('dietpi') ... the change password step of the setup appears to give both accounts the same password.
4. This is common among nearly every GNU+Linux distro these days: I want my systems to use UTC timezone ... but where most distros use a 'locale' setting to set a local timezone, DietPi assumes I'm in London. It chose BST as the timezone.
The good.
1. There doesn't seem to be a lot of unnecessary junk installed. I'm using a 16GB microSD card, so I don't want anything that isn't needed for the chosen task.
2. Uses #Raspian / Raspberry Pi OS and #Debian repos along with its own, so most of what I might want to install is available.
3. DietPi-Survey is disabled by default.

#Wi-Fi 6E is coming!

Was suddenly unable to print from #Win10. Tried all the standard tricks.
Then I realized what happened. Two routers / #Wi-Fi access points. When The computer connects to the closer of the two, the #WSD port decides the printer is "offline", even though I can view the printer's configuration web page with a browser. Went back to reliable TCP/IP port and multiple jobs flowed out of the print queue.
It's been a few years since I had to replace WSD (Web Services for Devices) port monitors to make printers work. Putting this back in my toolbox.

#lazyNephew revealed some previously undisclosed things he discovered on former neighbor Steve's open #Wi-Fi network. Apparently browsing an unsecured SMB share led to the neighbor's porn being discovered by his wife.
I can't say how much is true, but I did know about Steve's network.
-
On my cellphone ( AT&T #ATT_Wireless ), there's some weird proxy that interacts badly with this instance's security settings. I'm attempting to figure it out, but I might have to use a #VPN every time I'm away from #Wi-Fi until I figure it out.
This never happened with #Sprint.
-
@geniusmusing I never even knew that some grills are #Wi-Fi capable. If someone wants to track what I'm eating, they can talk to my bank. No need to give them a direct line to the grill.
-
@geniusmusing The routers at work are centrally managed by another agency, so no experience to recommend by. I know #sonOne is using a #Ubiquiti router with #Wi-Fi, but I don't know specifics.
-
@guizzy @moonman@shitposter.club I'm sure most of those don't even know they have a #VNC server running or don't even know it is accessible outside their networks. Perhaps they've got VNC as part of a virtualization system or built into some #IoT device they bought.
One of my sons installed VNC on his wife's laptop about 12 years ago, so he could support from another room. Within minutes after installation, he watched someone log in, download some malware, and install it on her computer. While some blame goes to his consumer grade #Wi-Fi router (and possibly him for not setting it up more securely; he's a lot more careful now), it was an important lesson for both of us: even your "private" network may have uninvited visitors, so you should set things up as securely as your users let you get away with.
So, yes, unless you can prevent all non-SSH connections, I'd never allow VNC on my network.

I should try out FairEmail on my phone. Something about Samsung’s power settings prevents K-9 from fetching messages except when I manually tell it to do so. This is even true on some #Wi-Fi networks.
-
I was seriously thinking the #Synology #NAS's weird permissions settings and the collection of client apps were too much hassle for a limited benefit. But being able to play the same song on every device I own when I'm in reach of the home #Wi-Fi is a powerful attractant.
Now that it is working again, let's see how long it takes them to fill 7TiB of space.

Huawei’s troubles continue to worsen. https://nu.federati.net/url/225434 In one form or another, they’ve been disconnected from standards & software or at least decision-making for: #Android #Wi-Fi #Bluetooth #SDCard #ARM
Not sure they’ll continue to be able to import the Matebook X into the US, either.

#sonOne gave seven year old #GD2 his old cellphone. There’s no service, but she uses it on #Wi-Fi like a mini-tablet. I’m not sure whether she has the communication program that we use, because she hasn’t responded since 2019-01-27. I’ll try to ask my son when I call tomorrow.
