Sovereign Tech Fund invests in Pendulum
This article is an adaptation of the original, published by Prossimo.
We're happy to announce that the Internet Security Research Group has officially made us the maintainers of the open-source memory-safe implementation of NTP, ntpd-rs. As such, we are now also looking for early adopters.
The implementation includes a server and client, as well as full support for Network Time Security (NTS), which brings encryption and greater integrity to time synchronization. Timing is precise and stable, as reflected by excellent performance in the NTP pool.

Our year in Rust
Our year in Rust
A company-changing year in a short story,
begins with a thank you, for this new-found glory.
We want to be clear in this prelude,
It is to Rust we owe our gratitude.

Implementing the Network Time Protocol (NTP) in Rust
For the last couple of months we at Tweede golf have been working on implementing a Network Time Protocol (NTP) client and server in Rust.
The project is a Prossimo initiative and is supported by their sponsors, Cisco and AWS. Our first short-term goal is to deploy our implementation at Let's Encrypt. The long-term goal is to develop an alternative fully-featured NTP implementation that can be widely used.

Instant data retrieval from large point clouds
The Dutch government offers the AHN [[1]](https://www.ahn.nl/) as a way to get information about the height of any specific place in the country. They offer this data by using a point cloud. That is, a large set of points with some additional meta information. With the current version of the AHN the resolution of the dataset is about eight points per square meter. This results in about 2.5TB of compressed data for the relatively small area of the Netherlands. While this is something that is not impossible to store locally, it does offer some challenges.
Open Data geeft het antwoord: hoe groen is mijn wijk?
While working on the Roc compiler, we regularly dive deep on computer science topics. A recurring theme is speed, both the runtime performance of the code that we generate, as well as the performance of our compiler itself.
One extremely useful technique that we have been playing with is data-oriented design: the idea that the actual data you have should guide how code is structured.
