I have been adding one tip per day to my daily tips GitHub repo for the past month. It’s a simple setup: I manually add tips to a YAML file I use a Python script to convert YAML to Markdown A helper script appends the Markdown file, README.md, with today’s tip I’ve also set up…
There’s this quote that is commonly attributed to Albert Einstein (though it’s uncertain whether he really said it or not): Insanity is doing the same thing over and over again and expecting different results. I first came across it a long time ago, when I was much less discerning. After reading it, I envisioned someone…
TL;DR Use git stash to stash changes. Update from remote using git pull. Apply stash changes to latest changes using git stash pop. If there’s a merge conflict, manually resolve using some text editor like Nvim. Changes from upstream and stash are demarcated with angle brackets. After resolving, add, commit, and push! Clean up stash…
I have been interested in machine learning since I was a PhD student back in 2010. I was always in awe of papers where they applied machine learning to cluster or classify data. My original PhD topic was to discover biomarkers in blood for Parkinson’s Disease (PD) patients that were early onset and had not…
I just heard about Open WebUI from Harish’s comment on my Ollama and DeepSeek post and decided to check it out. From their website: Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform designed to operate entirely offline. It supports various LLM runners like Ollama and OpenAI-compatible APIs, with built-in inference engine for…
I guess by now you have probably heard about DeepSeek. If in the extremely unlikely event that you have come across this post before reading about DeepSeek, please go look them up. When I first heard about them and their amazing LLM models, the first thing I wanted to do was to try them out!…
In April 2023, I had tried to get GPT4All, a tool to run LLMs locally, to work on one of my servers running Debian 12 at home without avail; I just couldn’t get it to install. (I have to say, GPT4All does look much more developed now compared to back then.) So when I learned…
The Gene Set Variation Analysis (GSVA) is another popular analysis method for bulk RNA-seq data. GSVA differs from Gene Set Enrichment Analysis (GSEA) in that it can estimate gene set enrichment within a single sample. GSEA typically uses results from a differential expression analysis, which requires multiple samples, to determine whether there is an enrichment…
The {GenomicDataCommons} Bioconductor package provides basic infrastructure for querying, accessing, and mining genomic datasets available from the Genomic Data Commons (GDC). The About the GDC webpage provides a brief description of the program: The Genomic Data Commons (GDC) is a research program of the National Cancer Institute (NCI). The mission of the GDC is to…
The Molecular Signatures Database (MSigDB) is a nice resource containing various gene sets designed for use in Gene Set Enrichment Analyses (GSEA) and its variants. It was co-developed with the GSEA by the Broad Institute and is still maintained by them; you can read more in the classic paper: Gene set enrichment analysis: A knowledge-based…
