What is PageRank algorithm? How can it be used in various graph database use cases? How to use it in Memgraph? If these questions are keeping you up at night, here is a blog post that will finally put your mind at ease.
Knock knock? Who’s there? It’s me, Oskar, the end is near, did you know that? Ah, you know it but don’t know how to proceed? Let’s talk about the end of the CRUD world…
Andy reviews his favorite NoSQL and NewSQL database shirts.
A couple of weeks ago, I was in an internal meeting where our CTO (Adam Prout) was giving a talk to our summer interns. The talk was about the current state of database companies, and how different providers are competing on different facets of their products. As the talk was
TigerBeetle is a distributed financial transactions database, designed for mission critical safety. How do you test something so critical? Well, we could tell you (and we will), but why not show you?
I’ve put in my fair share of time with PostgreSQL. It has no shortage of functionality and I believe its expansive feature set drove a lot of its growing popularity in the 2010s. As my time with the database has worn on I’ve come up with a handful of features that I wish the database had. Some of these are ideas…
For the first SpacetimeDB blog post, I’d like to clear up some confusion that I’ve seen arise in discussions about SpacetimeDB and address some general misperceptions about databases. My sense is tha…
Documentation and guides from the team at Fly.io.
I recently finished reading PostgreSQL 14 Internals by Egor Rogov. It is one of the great books that teach applied computer science without watering down the difficult parts. One particularly interesting topic is PostgreSQL’s execution of UPDATE statements. Updates in relational databases are inherently complex. They…
RedPajama-Data-v2 is a 30 trillion token open dataset from 84 CommonCrawl dumps across five languages, with over 40 precomputed quality annotations.
Craig takes a look at the history of Postgres. From the origins of the project through some of the key production features that make Postgres what it is today.
Why every database will become a vector database, sooner or later
I've been using SQLite in several production projects for six months, and I've encountered some surprising aspects.
Based on your feedback, we've improved the Automatic Data Conversion settings, and made them also available in Excel for Mac.
Spoiler alert: many of the good projects didn’t survive
Updated 2024-09-17 to reflect updated PgBouncer support for protocol-level prepared statements 🐘 To start, I want to say that I’m appreciative that PgBouncer exists and the work its open source maintainers put into it. I also love working with PostgreSQL, and I’m thankful for the incredible amount of work and…
States now offer a vast menu of personalized plate options for a dizzying array of organizations, professions, sports teams, causes and other groups.
Throughout much of the 20th century, frequentist statistics dominated the field of statistics and scientific research. Frequentist statistics primarily focus on the analysis of data in terms of probabilities and observed frequencies. Causal inference, on the other hand, involves making inferences about…
With Ubicloud PostgreSQL, we are releasing an open and managed PostgreSQL, and cutting your cloud database spend by 3x.
I have been writing a lot more Go this past year. For those not familiar, Go favours a non-ORM, non-query-builder approach to interacting with databases. This comes naturally due to the sql package : A common interface to be used alongside database drivers. It’s very common to see actual SQL in Go, even in large…
I analyzed stackoverflow for secrets and leaks.
Turns out the question of which identifier to use as a Primary Key is complicated -- we're going to dive into some of the complexity and inherent trade-offs, and figure things out
The Thanksgiving long weekend (23-26 November) in 2023 was an interesting one for OpenZFS, that I managed to land myself in the middle of. The short version of events is that an apparent silent data corruption bug was discovered, which is kind of the worst case scenario for a data storage system. It was a pretty…
Forgotten parts of RFC2616
SQLite is an embedded SQL database. It’s extremely easy to setup, buildable as a single C file with libraries existing for basically all common programming languages. It doesn’t need any server setup or configuration since the SQL logic is run in the host process, and the database consists of only
This is a very brief post announcing a fascinating discovery. It appears to be possible to use the cosine similarity approach powering explore2.marginalia.nu as a substitute for the link graph in an eigenvector-based ranking algorithm (i.e. PageRank). The original PageRank algorithm can be conceptualized as a…
