When data is extracted and transformed, it’s time to visualize and get the value from all your hard work. Visuals are done through Analytics and Business Intelligence and one of their Tools. The BI tool might be the most crucial tool for data engineers, as it’s the visualization everyone sees–and has an opinion on!

Analytics is the systematic... See more

Exon is an analysis toolkit for life-science applications. It features:

• Support for many file formats from bioinformatics, proteomics, and others


• Local filesystem and object storage support


• Arrow FFI primitives for multi-language support


• SQL based access to bioinformatics data -- general DML and some DDL support

the science problem. We’ve all spent the last year talking about ‘error rates’ or ‘hallucinations’ (indeed, I also wrote about them here). The breakthrough of LLMs is to create a statistical model that can be built by machine at huge scale, instead of a deterministic model that (today) must be built by hand and doesn’t scale. This is why they work,... See more

Idempotency is a concept that is important for programmers to understand, especially those working on building distributed systems. In simple terms, idempotency means that if you perform an operation multiple times, the end result should be the same as if you had only performed it once.

In other words, an idempotent operation is one that can be... See more

Denormalization

Another way Reddit minimizes joins is by using denormalization.

They took all the metadata fields required for displaying an image post and put them together into a single JSONB field. Instead of fetching different fields and combining them, they can just fetch that single JSONB field.

This made it much more efficient to fetch all the... See more

The newer branch has three primary functions. The first centers on the heart and its ties to respiration. As activity in the vagus—also known as vagal tone—increases, a person’s heart rate and respiration slow. The second function centers on the endocrine system. As vagal tone goes up, the release of stress hormones in the body goes down. Higher... See more

Short-term stress and the release of epinephrine are important for combatting infection through inflammation. It also brings certain aspects of your brain alive to narrow your focus to do intentionally actions. Epinephrine releases the killer cells in the immune system that clean the system. Super-oxygenation breathing (Wim Hoff) liberates... See more

Many video games involve a concept of a skill tree. For those unfamiliar, a skill tree is a sequence of skills or abilities that are unlocked as the player progresses through the game. Each skill is unlocked by spending skill points. Here s the rub: at any given time, there are more skills to unlock than you have skill points to spend. The skill... See more

Red blood cells turn over roughly every 120 days. They offer many interesting more long term biomarkers for health (e.g. Omega-3 index).
