• Mounting an NFS Drive at Boot in WSL (23 Sep 2024)
  WSL fails to mount a NFS drive defined in /etc/fstab. Here is an easy fix.
• Fix a 404 error when a folder without index.html is linked on GitHub Pages (22 Sep 2024)
  GitHub does not serve root URLs (ending with a "/") unless there is an "index.htm". Good to know!
• Distributed asynchronous parallelized hyperparameter optimization with Ray (18 Sep 2024)
  Hyperparameter optimization is crucial for obtaining an accurate neural network. Typically, this is done through a Bayesian optimization by running a set of trials sequentially. With Ray and Ax, however, we can distribute the optimization across all allocated resources. This approach significantly reduces the wall time required for completing these tasks.
• Copy location metadata with exiftool (17 Sep 2024)
  A shell function to copy the GPS location from one media file to others
• Export each layer as a file in Photoshop with a script (14 Sep 2024)
  A Photoshop script to export each layer as a file using the the layer name as the filename.
• 3D print a QR code for this site for ACS Spring 2024 (13 Mar 2024)
  I will be attending the ACS Spring meeting in New Orleans next week. I thought it might be useful to make a QR code for this site so that I could use it while networking. Instead of print a 2D image, I decided to make it 3D.
• Predicting "protein-protein interactions" with neural networks (08 Mar 2024)
  Use a convolutional neural network to predict if a pairs of proteins interact with each other, part 3.
• Predicting "protein-protein interactions" with neural networks (06 Mar 2024)
  Use a convolutional neural network to predict if a pairs of proteins interact with each other, part 2.
• Monitor Nextcloud server with Prometheus and Grafana (29 Feb 2024)
  A tutorial to export stats from Nextcloud's server to Prometheus and Grafana
• Build GitHub Pages locally with Jekyll on Alpine (28 Feb 2024)
  The workflow is the largely the same with what is on WSL, but with some Alpine specific things and LXC settings.
• Host Grafana and Prometheus inside a Alpine LXC (28 Feb 2024)
  A tutorial to install and run Grafana and Prometheus on Alpine
• Build GitHub Pages locally with Jekyll (26 Feb 2024)
  When you are working with Github Pages, it is such a pain to test it, especially if you are working on something like this Jekyll-based site. Without setting up a local environment, to view any change, you have to git commit and push, then wait until GitHub to have your site updated. I decided to follow the official tutorial to do it myself.
• Predicting "protein-protein interactions" with neural networks (25 Feb 2024)
  Use a convolutional neural network to predict if a pairs of proteins interact with each other, part 1.
• SSL certificate and LAN domain resolution with AdGuard Home and Nginx Proxy Manager (24 Feb 2024)
  A tutorial to use AdGuard Home and Nginx Proxy Manager to certify self-hosted services and access them without the need of port numbers

• Show PVE host system load on Homepage LXC (26 May 2023)
  A tutorial to resize the system partition of a virtual machine

2022

• Host Homepage inside a Alpine LXC (05 Dec 2022)
  A tutorial to set up the Homepage project for Alpine Linux from scratch
• (Physically) install my OctoPrint server (19 Mar 2022)
  A quick and dirty way to mount the OctoPrint printer under the desk.
• Enlarge the system partition of my Debian VM (10 Mar 2022)
  A tutorial to resize the system partition of a virtual machine

• Fixing Synology DS2415+ (24 Apr 2021)
  There is a hardware bug in certain Intel Atom CPUs. These CPUs will degrade over time and eventually the computer will not boot up due to the clock issue of the CPU. Funnily, fixing the problem only need one resistor to be soldered on the motherboard. The only thing is that the CPU will die again and by that time, there is no way to fix it.
