  • Look at mister fancy pants with and assembler.

    How about entering straight opcode, operand with only a hex keypad and two pairs of 7 segment LEDs. You can only see one set of numbers at a time. You had to write it out on paper to be able to keep track and count positions so you don’t use your spot.

    I had to do this as a project in school. Two 8088 units that we breadboarded to a UART that we used to drive a fiber optic link to communicate with each other with a basic protocol. All descrete components hand wired and coded.

    It made you tie all of skills together into a full system of hardware and software.







  • Even Nvidia video works out of the box without any additional drivers.

    The thing with Nvidia is that although the default drivers work, they are more generic and don’t take advantage of all of the features and performance of recent cards. Most people would want to load the proprietary drivers from Nvidia to take full advantage of the card.

    Linux would normally include the better drivers, but Nvidia keeps them under a software license that prevents Linux distributions from bundling them.

    Even with this, Ubuntu includes a tool that will download and install these drivers that they can’t


  • You don’t need any internet connection to install Ubuntu. Just use the normal install, not minimal network installer. Install from a USB stick.

    Also, there’s no requirement for a wire either. If that were the case, you could never install on any modern laptop.

    You would need some sort of functioning network to upgrade packages or install anything not in the base image, but this would all be after installation when you have a working OS and wired or wireless won’t matter.



  • Code security is directly proportional to the amount of resources devoted to finding and fixing bugs regardless of open or closed. If nobody is maintaining the code, it doesn’t matter.

    One advantage with open you is that you can look at the version control to see how active the code is being maintained.



  • Use a tool to push sideways on the joints and from the component side.

    Bad looking joints can still have a connection even if they look bad. If the connection has truly come loose, there will be some movement in the joint.

    When we were working on surface mount boards, we would use a sewing needle and run it down the pins, and listen to the sound. The needle crossing a solid pin will make a sharp sound. If solder joint is not good, the pin moves, and you will get a duller sound. Dink, dink, dink, dut.



  • I have had various sticks and Roku highest end models and then got the latest ATV with hard wire port that adds Dolby vision and high frame rate HDR. I have a 2022 high-end TV.

    The video quality is noticeably better. Not sure of older ATV, but this is clearly better than the top end Roku. Also, I’m not sure if it is the same on older tvs

    The other thing is that you want to hard wire if at all possible. Even the best wifi can’t touch the reliability of a wire
