    Maybe I do not understand the vector here, but I think you should be able to use a DNS filter log, like a whitelist firewall. Use the log to see what servers are blocked when you try to open the app. Then just whitelist those servers.

    The proper argument is not for Ad Block. That is just a lazy hack. The proper argument is that you have a right to a front door on your home – a digital front door, a right to lock it, and a right to decide who may enter your home. This is what a DNS whitelist filter does. If you are not allowed to use a DNS whitelist, your home has had the door ripped off and are being forced to allow stalkers, thieves, and slavers into your home to manipulate and exploit you. Never talk about ad block. That is politically irrelevant. I do not care if the lock on your front door in the real world has great pick resistance. It is just as much a symbol as it is a device. The primary reason for losing rights is from people failing to argue well, and understand their rights like this. I am one of the few people that does DNS the hard way and run a whitelist filter.

    They are nice for keeping tools around on spare SD cards that you might not want to run normally. Like that is a good way to look at Parrot or Kali Linux setups.

    Checking out how to build an OS from scratch is also handy. It can be an interesting low risk way to explore building Gentoo, Arch, or Linux From Scratch.

    The main appeal IMO, is that you have microcontroller like input, output, and serial communications already setup in the kernel with access in user space. As long as the kernel is supported by the Rπ foundation, (it is proprietary undocumented hardware that only they can support), you are getting the security updates required to keep the thing online automatically and safely. The best stuff to build is unique stuff for you that uses these aspects. Like make a little bathroom clock with a little TFT LCD display that tells you the local weather. Then set up some RSS feeds for local community stuff you do not want on your main mobile device, like maybe local political activity, library and community center events, concerts, clubs, etc.

    For server stuff, I would stick with devices with purpose built hardware. Like, a micro SD card is slow and unreliable, and the lack of nvme is bad. In most cases it is cheaper to use other old devices that already have screens unless you want to share a hardware design that is repeatable, you need something secure to keep online, or you need serial or input/output. Those are the main benefits.

    The thing is, the Rπ is what it is. It is the path of least resistance. The software support is approachable and great. The price is cheap. However, the non profit thing is a scam. The Rπ foundation is basically an arm of Broadcom. The Rπ is a chip from a set top TV box with 3/4 of the die unused. Broadcom uses excess fab capacity to make the Rπ chips and sell them at materials cost. This is not charity. It is controlling the grass roots market to make competitive scaling business ventures difficult. This is why Rockchip is not crushing them already. The Rockchip RK3588 chip is fully documented and open source. In this space, there is little to no innovation, it is only about price on ancient trailing fab nodes. This is the ladder to climb that leads to Intel, AMD, Samsung, and Qualcomm. The Rπ is the guy kicking anyone that tries to climb. So… use it for what it is good for, but in most cases, other hardware is better, and there is nothing wrong with saying so, or moving past the Rπ. I’m lying next to a RK3566 machine right now, sorting out issues with the ARM version of Fedora Workstation, looking at how to build the native WiFi module for it from source, and maybe try debugging an issue in that module’s code that is causing a memory race condition. Although that last one is past my typical pay grade. - So I’m not all fluff here.

    That is just my $0.02.

    That was for the limitations of incandescent lights, plastics, and mold manufacturing limitations of the era.

    Printing would be a question of the optical properties of the resins. It is common to find simple light pipes with 90° angles in products now. Worst case scenario, I would make it a two piece design where the lower body accepts small fishing line. Typical colorless fishing line is basically a fiber optic wire without an optical design specification. So just insert that to route the digits for each key. It would look like an old school HP alphanumeric dot display. Glue the line on the back side of each key with epoxy, then use a carefully designed raser jig to cut/terminate each line. Finally, add a printed lens diffuser.

    I haven’t messed with resin and it probably would not work, but if a jig to remount and align keys to the resin printer plate were possible, I could see skipping the second lens diffuser, scuffing the surface of the top of each key before attaching each strand of fishing line, and then printing the rest of the key over top of the strands so that the light is only passing through the semi opaque plastic with no indication of character without the backlight. It would be interesting to mix my experience as a pro automotive painter & graphics/airbrush artist to mess around with aesthetics of a resin applied in stages and intermediate surface finishes. A UV cured resin cannot be all that different than the stuff I am more familiar with.

    If there were cheap, open source, resin 3d printers with an open slicer, I would be tempted to design a keyboard that uses light pipes and 2-4 LEDs per key to make something like this. Many early electronic display devices worked like this. Like some of the early Apollo program hardware NASA used were just little incandescent bulbs barely more than a Christmas lights. These were angled and projected onto a plastic lens with specially angled facets on the back that created a pathway for one of eight bulbs to create a numerical display. Fran’s Lab on YT tends to show off stuff like this. It should be possible to make a similar light pipe design for multiple key backlights.

    I would probably get too side tracked in making printable mechanical keys.

    Still using pixel 6. When they stole my battery with their bullshit, I went and got a open hardware tablet running a Rockchip processor with Arm Arch and a full datasheet. If open hardware exists whenever the criminals quit security updates for this orphan kernel exploit, I will gladly buy it. I don’t care who makes it or what the specs are. If it has basic functionality, I’m fine with that. Mainline kernel support with fully documented hardware is god. I don’t care if it is two or three times more expensive. If there are no strings attached, and I can own it for life, I will buy it. Funding this criminal world is what I hate more than anything else.

    The color schemes of default piefed do not have a very pretty and low power OLED option.

    I want the ability to turn off downvote visibility where I can view it with a toggle but not by default. I would make more posts that drive engagement without that negativity.

    It would be nice if we had a small semantics model running on the server that could assess the negativity and value of comments with an optional filter for comment visibility. There are relatively few squeaky wheel type users and (likely) bots but they have a disproportionate impact on everyone. Basically, I am saying, a genuine, real person should have an option for a beehaw administered and moderated experience through basic toggles and automaton. Like I want the negative feedback on some things, but there are posts where I know there will be a fraction of toxic people with authoritarian views and I simply do not care what fascists have to say. Or make a simple filter that looks at a voter’s statistics overall and drops votes from view when the person is a major outlier for negativity. This is only about enabling good people to post real stuff and be more open. I can only speak from experience, and my history of posts on this and my other main account show that I would post a whole lot more if it were not for the few toxic people and interactions.
