Ram's Technology Notes
I finally followed through in setting up and sharing my Canon MP620 through my Linux homeserver with CUPS. This part is straightforward – install cups, cups-backend-bjnp (for the network communication with the MP620), gutenprint (for printer drivers) and then going to <host>:631 and adding the network printer using the printer’s static IP address (CUPS network…
I ran a bunch of updates on my Manjaro Linux laptop and noticed that printing from the laptop stopped working – this is the same setup where I was happy with how easy the setup was to print wirelessly to my MP620. The issue turns out to be the update doesn’t automatically update CUPS configuration…
Don’t overthink it – your .pyx is converted to a .c file and then converted into a Python callable extension module. This can be confusing at first – including, what language are you coding in? Essentially you are coding in Python, with some extensions/limitations that allow you to mix in some C like constructs and…
What is Cython and what do I use it for? Cython is an extension of the Python programming language that enables C/C++ and Python interop as well as speeding up Python code. There are three main use cases for Cython: Exposing functionality written in Python to native code written in C/C++ – this use case…
tl;dr: If you are having problems with the Kasa three-way switch in a four-way circuit where the Kasa app and Alexa don’t see the right state of the circuit (on/off), make sure you replace both three-way switches in the circuit with HS210 switches. That will fix the problem. For a change, I’m writing about some…
As mentioned before, I am trying to setup and run the fastai notebooks locally to get some hands-on exposure to deep learning. Unfortunately, if you are running this on Windows or have a very low-end GPU environment like myself you will run into additional problems. First, on Windows, I was hitting the error _share_cuda_ operation…
I decided to learn a little bit more about deep learning in practice and bought the Deep Learning for Coders with fastai and PyTorch: AI Applications Without a PhD book to help me get some hands-on exposure to deep learning. I did get the notebook and first examples running on gradient but I was also…
As I mentioned here, I have been running Manjaro Linux on my home laptop for almost a year now and for the most part it has worked well. My setup is that most of the useful storage is on my home server and I was mounting these as SMB shares on the laptop. Initially, I…
After a pleasant year of using Manjaro Linux on my laptop at home, I started seeing problems with SMB mounts. My setup is that I have all of the main storage on my home server which is shared through SMB shares and these shares are mounted on the laptop through SMB4k. SMB4k started doing strange…
I have been running Manjaro Linux on my main home laptop for a change for the last 9 months. Overall, experience has been excellent with almost all the hardware working very well, battery life being very good, wake from sleep being near instantaneous and the laptop being very functional for my workload. I had however…
