I got curious about the Raspberry Pi serial connection recently so went about getting it to work on mine. It’s mostly for fun but I can see the benefit when I want to find out the IP address of my Pi without having a monitor and keyboard on hand. Plus, I this would benefit the classes I plan on running as I may not have extra monitor and keyboard for the classes.
I managed to find my I2C OLED display when I was cleaning up my place. As I currently have a S3 storage cluster project ongoing, I figured now would be a great time to get it working so I can attach an OLED display to each of the Raspberry Pis so I can get their status on a glance. Below are the steps I used to get it working on Rasbian Lite.
I’m working on a new project involving a Raspberry Pi Zero W running ArchLinux ARM. The Pi Zero W, being with only 512MB RAM is having issues performing a task I need that must be done in memory using the vendors command line app. I could rewrite the vendor’s app to be able to run on the 512MB RAM but I’m keeping that for the future. Aside this, there might be other apps that need a little more RAM.
After installing ArchLinux ARM on my Raspberry Pi Zero W and getting the wireless up and running, I reset my keyring using pacman-key --init because pacman told me so. However, this messed up my entire keyring for ARM packages and nothing could get it working again. After some Googling, I found a solution provided by some kind soul who encountered a similar problem. The command to fix your keyring for ArchLinux ARM is
Developers all over are familiar with the various Version Control systems available. Most developers would have used SVN, Git or Visual SourceSafe over the years at work or personally. The most popular Version Control service, GitHub has thousands of users and repositories available. Just ask yourself if Made a change to code, realised it was a mistake and wanted to revert back? Lost code or had a backup that was too old?
Anyone with a sprawling collection of e-books know that managing them manually can be a real pain. It’s even more so of a pain when you want to share the books with others or load them up to your devices. Sure you can load them up on iTunes and transfer it to your iPad but that won’t work with an Android device. I have a spare Raspberry Pi with an old HDD so I figured why not just set up a digital library so I can load up my novels, magazines, RPG manuals, game rulebooks to my devices over the WiFi.
It’s been a while since I did a fresh install of Raspbian AND needing WiFi immediately. My previous setups involved flashing the MicroSD card and connecting it via Ethernet to my test network. However, today I needed to setup a fresh Raspbian with WiFi and SSH out of the box. A few minutes of looking at Stack Exchange (a real God send) and Raspberry Pi forums I found a neat way to do it.
