What I found interesting in tech, July 2021

Here’s 59 links (!) of things I have found interesting in tech in the last while.

It ‘s heavily skewed towards Kubernetes because that’s mostly what I have been involved with. Some stuff on Helm, since I was working on a tricky situation with Helm charts. There’s some docker and Open Shift of course, since it’s related. There’s a few general pieces on cloud. And finally at the end there’s links to a bunch of worthwhile repos.

Almost all of these links are self explanatory. The ones that aren’t…well…few if anyone but me reads these posts anyway. 🙂 Just treat it like a collection of potentially good resources.

Raspberry Pi / Pico: I have been interested in doing work with the Raspberry Pi Pico, so here are some links I liked:
Raspberry Pi Pico: Programming with the Affordable Microcontroller and Getting started with Raspberry Pi Pico – Control LED brightness with PWM | Raspberry Pi Projects and How to Use an OLED Display With Raspberry Pi Pico | Tom’s Hardware.

I am interested in getting bluetooth working with my Raspberry Pi Pico, so I am reading things like Bluetooth serial communication with Mac, JY-MCU Bluetooth and Arduino | Cy-View and How to: Setup a bluetooth connection between Arduino and a PC/Mac | ./notes and Cheap BlueTooth Buttons and Linux – Terence Eden’s Blog

Not a Pico, but I am also interested in doing work with the ATTTiny 85 chip, so I saved this: How to Program an ATtiny 85 Digispark : 8 Steps – Instructables

Here’s two projects I am interested in. Using a Pico to press a key on the Mac using bluetooth: How to run an AppleScript with a keyboard shortcut on macOS while here is a fun project – Making an Email-Powered E-Paper Picture Frame

Here’s some cool MIDI projects with a Pico: this one, NEW GUIDE: Modal MIDI Keyboard @adafruit @johnedgarpark #adafruit #midi « Adafruit Industries – Makers, hackers, artists, designers and engineers, this Code the Modal MIDI Controller | Modal MIDI Keyboard | Adafruit Learning System, and this Build smart, custom mechanical keyboards for MIDI – or really tiny Ableton Live control – CDM Create Digital Music

Kubernetes/OpenShift / Containers: I’ve been doing more and more work on K8S and OpenShift and found these useful…

Cloud: some advanced cloud knowledge here:

Software Development: here’s some random dev links:

 

 

General: finally here are some interesting links on IT in general:

What I find interesting in tech, May/June 2021

Here’s what I found interesting lately in tech, from cloud to coding and lots more.

Cloud: I’ve been doing lots of work on Azure recently. Some things I found useful were this listing of Virtual machine sizes Also disk types. This piece on how to expand your virtual hard disks on a Linux VM was good. If you want to run Websphere on Azure, read this: Run WebSphere Application Server on Azure Virtual Machines.  If you want to learn more about deploying applications in Red Hat, read this. Finally here’s some good stuff from IBM on
Cloud Architectures.

Coding: If you want to print coloured text in Python — and who wouldn’t? — this is good. If you want to turn your HTML into an RSS feed, read this.  This will help you set up VS Code to do PHP Development. For people wanting to learn more about machine learning, IBM can help you. If you love Prolog or Javascript — or both! — check out: Tau-Prolog

Raspberry Pi/IOT: This is a great guide on how to troubleshoot problems with a Pi. This is a cool project using an OLED to make a clicker counter. If you need to load an OS or anything else on a Flash card, check out balenaEtcher. Here’s some advice on getting started with Bluetooth Low Energy. If you want to connect a raw serial terminal to a bluetooth connection, read that. If you want to do a cool Raspberry Pi Pico project with a MIDI, see this.

Fun and cool: Not a real Captcha, but a real fun one! DOOM Captcha – Captchas don’t have to be boring. Also fun: Crappy robots, ranked!. As an old user of 3270s, this downloadable version of 3270 fonts is awesome. Speaking of cool, here’s kinda the source code for Eliza! Check it out.

Other: Here’s some help on how to control smart home devices using speakers and displays. Here’s a good reminder that robots have a way to go yet: Peanut the Waiter Robot Is Proof That Your Job Is Safe. Developers! Here’s What’s Hot/What’s Not in terms of skills. Finally, have you considered how to
write software that lasts 50 years?

Tech Stuff I am interested in, Arduino edition, March 2021


Last March at the beginning of the pandemic I was doing a bunch of Arduino projects. I stopped for some reason. Well, a number of reasons. But I want to get back at it and dive back into these sites.

If you are interested in working with an Arduino, check these out:

  1. Circuito.io: a good site to draw and plan out circuits!
  2. Using Arduino with a Nokia 5110 screen
  3. How to use bluetooth and Arduinos together
  4. More on using bluetooth and Arduinos together
  5. How to use Infrared receivers and Arduinos together
  6. A good tutorial to start you off
  7. How to use LEDS and Arduinos together
  8. How to use LCD displays and Arduinos together
  9. How to use temperature displays and Arduinos together
  10. Morre on LCD displays
  11. More tutorials
  12. A classic intro: getting an LED to blink
  13. How to use Raspberry Pis and Arduinos together
  14. How to use Arduinos to check your website
  15. More on bluetooth
  16. How to use a 16×2 display and Arduinos together

A bonus Raspberry Pi section

Finally, the homepage for Arduino is here.
