The One Billion Row Challenge Shows That Java Can Process a One Billion Rows File in Two Seconds

Well, it’s way under 2 seconds for the 1brc. The published results are in, and if you’re good, you can read 1 billion data points of weather data and analyze it. The final best number, as per the article release, is “00:00.323″. Yes, that answer is in milliseconds “Result (m:s.ms)”. Mind-blowing.

ScyllaDB Summit 2024

Last week, I attended this virtual event. All the presentations can be found online. I had never used the product before, so while some new features like Tablets were not as applicable in understanding the full impact, the DynamoDB performance and cost comparisons were very applicable.

So what is ScyllaDB? It is a distributed NoSQL DBaaS that speaks Cassandra protocol (do large companies still use this?), and it speaks AWS DynamoDB protocol. That is really interesting to me. You can choose a Cloud Hosted offering, or if you’re into managing your setup, you can use the Open Source ScyllaDB version available from GitHub. I started at ScyllaDB University to get a grip on the basics. I have yet to try the local Docker Compose setup.

Thanks also to the team for the swag which I received.

Playing a game with your CI/CD pipeline

My friend Sergey has created a game in GitLab called GitTerra. Drop a few lines into your .gitlab-ci.yml, and each build will give you a generated 3D map of a city based on your commit. I look forward to some of his next steps, leveraging potentially different colors for languages or different building structures for artifacts found in your commit.

We raised 11.6M to build Serverless Postgres for Modern SaaS

Congrats to Gwen and her co-founder for getting seed funding for Nile Serverless Postgres for Modern SaaS. Awesome news for an entrepreneur, and I’m very hopeful for the success of Nile.

The Safest Way to Test Postgres Destructive Queries

While I am a user of ElephantSQL serverless PostgreSQL and Neon, Nile and Xata are just a few that are competing in the space. With multiple other products that also speak PostgreSQL protocol, you can easily trial a small product in an RDBMS in the cloud at no cost. PostgreSQL is definitely outdoing MySQL in this space. You have the extensive set of NoSQL Cloud offerings, SycllaDB I just mentioned, and D1 by CloudFlare I have yet to try this branching feature for your database, sounds interesting and I’ve added to my just as long list of products to try, as books to read. Nit: It’s PostgreSQL, not Postgres.

About “Digital Tech Trek Digest”

I take some time early in the morning to scan my inbox newsletters, the news, LinkedIn, or other sources to read something new covering professional and personal topics of interest. Turning what I read into some actionable notes in a short, committed time window is a summary of what I learned, what I should learn and use, or what is of random interest. And thus my Digital Tech Trek.

Some of my regular sources include TLDR, Forbes Daily, ThoughWorks Podcasts, Daily Dose of Data Science and BoringCashCow. Also Scientific American Technology, Fareed’s Global Briefing, Software Design: Tidy First? by Kent Beck, Last Week in AWS, Micro Newsletter to name a few.

Everything you need to know about seed funding for startups

A recent call with a startup founder funded by TinySeed led me to learn about MicroConf and Rob Walling. (Thanks Tony for the info). This has led to a lot of great info in several new newsletters and videos including this video. A few very valuable tips I learned included the answer to Why should you raise funds at all? The 1-9-90 rule, and different types of funding including Indie funding. It was interesting to find out that the TinySeed accelerator is 1 year, and not 13 weeks, which is common in NY. Rather than sharing my notes, go watch the video.

5 Books That Paved My Path to Entrepreneurial Success

I have not heard of any of these books, and I have such a long list, perhaps I need to publish my list and elicit feedback on prioritizing. The list from this article is as follows:

    1. Mastering negotiations with never split the difference
  1. 2. Embracing risk with skin in the game
  2. 3. Building habit-forming products with Hook
  3. 4. The roadmap to a billion dollar app in How to Build a Billion Dollar App

Visualization

Last week I was at two events in Brussels. I chose to head to London to fly home. I found this map present in many tube stations (The tube is the London Metro Subway). It’s been a decade since I was in London, and over two decades since I lived in the UK. I found the new map great. When I mentioned it as a good visualization, I was surprised that locals of the London area thought it was horrible. I saw the value in the visualization, but perhaps others see it like art, “in the eyes of the beholder”. It could also be “habit”.

Cats and Dogs

How many *NIX `cat` memes can there be? Well, a lot cat is the most misused thing by programmers new to Linux. I cringe every time someone uses it wrong in a bash script. Thread below with proper uses of cat only.

Hey, dogs, you are in the count also with HTTP STATUS DOGS. My picks are 300 Multiple Choices, and 429 Too Many Requests for me.

Upcoming Events on my radar

Random

I shared with a colleague on Feb 9. “3 SQL databases walked into a NoSQL bar. A little while later, they walked out because they couldn’t find a table.”
