It is good practice to regularly inspect the statements running in the hot path of your Postgres instance. One way to do this is to examine the pg_stat_statements view , which shows various statistics about the SQL statements executed by the Postgres server.
[This post is about the day that Glitch failed, and how that failure created the opportunity to make Slack. We're sharing it here (out of chronological order) to mark 12 years since the famous pivot.] “We have to shut down the game.” Stewart Butterfield said. I looked at him
Why we use our own hardware and what the tradeoffs and costs look like
This is the story of an investigation conducted by Jochen Sprickerhof, Helmut Grohne, and myself. It was true teamwork, and we would have not reached the bottom of the …
last week at NeurIPS’24, one extremely salient thing was the anxiety and frustration felt and expressed by late-year PhD students and postdocs who were confused by the job market that looks and feels so much different from what they expected perhaps when they were applying for PhD programs five or so years ago. and…

Trying to speedup my lexer using lookups and bitvectors but simd was just a step to far for me.
I knew that data tables had been around a long time, but I didn't appreciate how long until I read recently about account-keeping in ancient Mesopotamia.
Improve startup time by making the classes of an application instantly available, in a loaded and linked state, when the HotSpot Java Virtual Machine starts. Achieve this by monitoring the application during one run and storing the loaded and linked forms of all classes in a cache for use in subsequent runs. Lay a…
Division is quite an expensive operation. For instance, latency of the 32-bit division varies between 10 and 15 cycles on the Cannon Lake CPU, and for Zen4 this range is from 9 to 14 cycles. The latency of 32-bit multiplication is 3 or 4 cycles on both CPU models.
Introducing S2, a serverless stream store that makes durable real-time streams feel as simple and scalable as object storage.
if $n \equiv 0 \, (\text{mod}\, 2)$ the ant turns 90º clockwise, else the ant turns 90º counter-clockwise. On both accounts, the state of the cell is flipped and the ant moves forward one unit. This is repeated until $n = 1$.
The ride is coming to an end. The experiment is done. We tried, but we admit defeat. Four years ago we started adding support for an alternative HTTP backend in curl. It would use a library written in rust, called hyper. The idea was to introduce an alternative implementation of HTTP internals that you could ……
A year-long investigation by an indie journalist is a call to action
What did you do at work today? How about last week? I spent a couple of days in quarterly business reviews, and wrapped up yearly planning activities for AWS Data Exchange and AWS Marketplace. I also added some unit tests to a project that I am onboarding into.
For LLM of equivalent performance, the inference cost is decreasing by 10x every year. What cost $60/million tokens in 2021 costs $.06/million tokens today.
A popular data-oriented design pattern is a Struct of Arrays. Is an Array of Enums also useful? Yes! But let’s do a refresher on struct of arrays (SoA) first:
An interactive introduction to Turing machines, the theoretical foundation of modern computing.
For a long time, I couldn’t quite grasp what the DOS APPEND command could possibly be good for. Until I came across a situation which APPEND was made for.
OpenAI o3 scores 75.7% on ARC-AGI public leaderboard.
I recently built a website that breaks down the cost of a UK electricity bill. It's interactive, and I'd recommend visiting it before reading this post. Check it out here: electricitybills.uk Here are three interesting things about the data. #1: The wholesale power cost is only one third of
Practical guidance from Anthropic on building reliable AI agents, from simple composable patterns to fully autonomous systems.
In order to give myself and the many tired volunteers around WordPress.org a break for the holidays, we’re going to be pausing a few of the free services currently offered: New account registration…
Understanding the safety impact of Automated Driving Systems (ADS) is crucial for their widespread adoption, yet robust real-world evaluation remains a critical area of development. By leveraging insurance industry third-party auto liability claims, we analyze the Waymo ADS performance across 25.3 million fully…
