webviz VS tenzir

For the web based part, in terms of integration with ROS RobotWebTools (especially with RoslibJS) and rosbridge cover already a lot, so maybe you may want to first check what's available there. Webviz is also a great web based tools with many components for visualisation.

Hey HN, one of the creators here! I made it at Cruise because it was super painful to develop https://webviz.io with manual memory management (lots of ArrayBuffers), WebWorkers, etc. I thought that there must be a better way.

Very curious to hear stories from other folks building intensive stuff in the browser. How are you dealing with performance issues in Javascript? Have you tried using Rust or C++ with WebAssembly for parts of your apps? How did you make 2d/3d rendering faster? Would you want to use something like Zaplib?

Webviz is a great tool. Just drag the .bag file onto the browser window and you can start viewing the data.

Webviz is actually open source for the most part. https://webviz.io

Cruise | Software Engineer | San Francisco, Seattle, or REMOTE | VISA acceptable | https://www.getcruise.com

Cruise is building the world’s most advanced, self-driving vehicles to safely connect people to the places, things, and experiences they care about. We believe self-driving vehicles will help save lives, reshape cities, give back time in transit, and restore freedom of movement for many.

I'm an engineering manager hiring specifically for the Webviz (http://webviz.io/) team. I'm looking for frontend engineers who want to make fast, beautiful browser-based visualizations of the car using WebGL, WASM and Javascript.

Much of the work that we do on this team is open-sourced (check out the code at https://github.com/cruise-automation/webviz). Cruise vehicles produce mountains of data; we have to visualize it in dozens of different ways at a high frame rate. We recently built a Javascript object proxy that wraps all of our input binary data in an object-like interface that only parses data on access, so that we can limit garbage collection pressure and improve our frame rate. If this kind of project sounds interesting, you might enjoy working on Webviz!

Reach out directly to me if you're interested in the above (open to associate/senior/staff levels), or if you have any questions about Cruise.

PS - for those of you who have seen or used Webviz, Foxglove may look familiar. Some of our team previously worked on Webviz at Cruise, and we reused much of their code, although it has been heavily refactored, several new features added, and we have more coming soon.

We're building something similar at Tenzir, but more for operational security workloads. https://docs.tenzir.com

Differences to Vector:

- An agent has optional indexed storage, so you can store your data there and pick it up later. The storage is based on Apache Feather, Parquet's little brother.

- Pipelines operators both work with data frames (Arrow record batches) or chunks of bytes.

- Structured pipelines are multi-schema, i.e., a single pipeline can process streams of record batches with different schemas.

Tenzir | Remote (EU) or Hamburg, Germany | open-core | Full-time | https://tenzir.com

Tenzir is hiring several key engineering roles to meet the needs in expanding the team. Our product: security data pipelines. From the data side, think of it as an Arrow-native, multi-schema ETL tool that offers optional storage in Parquet/Feather. From the security perspective, think of it as a solution for collecting, parsing, transforming, aggregating, and routing data. We typically sit between the data sources (endpoint, network, cloud) and sinks (SIEM, data lake).

Our open-source execution engine is C++20 (https://github.com/tenzir/tenzir), our platform is SvelteKit and TypeScript. Experience with data-first frontend apps is a great plus. Open positions at https://tenzir.jobs.personio.de:

We're in the middle of getting TQL v2 [] out of the door with support for expressions and more advanced control flow, e.g., match-case statements. There's a blog post [#] about the core design of the engine as well.

While it's a general-purpose ETL tool, we're targeting primary operational security use case where people today use Splunk, Sentinel/ADX, Elastic, etc. So some operators are very security'ish, like Sigma, YARA, or Velociraptor.

Hey, founder of Tenzir [1] here — We are building an open-core pipeline-first security data engine that can massively reduce your Splunk costs. Even though we go to market "mid stream" we have a few users that use us as light-weight SIEM (or more accurately, just plain log management).

We are still in early access to browse through our docs or swing by our Discord.

Download VAST v3.1 here: https://github.com/tenzir/vast/releases/tag/v3.1.0

Tenzir is a funded seed-stage startup that builds a next generation data-plane for plug-and-play security operations. Our mission is to empower defenders with an open data engineering platform to perform data-driven investigations through combination best-of-breed solutions. Our stack consists of the high-performance C++20 telemetry engine VAST, a Rust API, and a ReasonML-based frontend.

I had chat with Hannes, the DuckDB co-founder, a few weeks ago. They are building awesome stuff to become the "SQLite of OLAP". The team comes with a strong academic background and is tuned into the data engineering world.

At Tenzir, we looked at DuckDB as embeddable backend engine to do the heavy lifting of query execution of our engine [1]. Our idea is throwing over a set of Parquet files, along with a query; initially SQL but perhaps soon Substrait [2] if it picks up.

We also experiment with a cloud deployment [3] where a different set of I/O path may warrant a different backend engine. Right now, we're working on a serverless approach leveraging Datafusion (and depending on maturity, Ballista at some point).

My hunch is that we will see more pluggability in this space moving forward. It's not only meaningful from an open-core business model perspective, but also pays dividends to the UX. The company that's solving a domain problem (for us: security operations center infrastructre) can leverage a high-bandwidth drop-in engine and only needs to wire it properly. This requires much less data engineers than building a poorman's version of the same inhouse.

We also have the R use case, e.g., to write reports in Rmarkdown that crunch some customer security telemetry, highlighting outliers or other noteworthy events. We're not there yet, but with the right query backend, I would expect to get this almost for free. We're close to being ready to use Arrow Flight for interop, but it's not zero-copy. DuckDB has demonstrated the zero-copy approach recently [4], going through the C API. (The story is also relevant when doing s/R/Python/, FWIW.)

To this end, we build the high-performance telemetry engine VAST, which at its core, ingests hundreds of thousands of events per second from high-volume data sources (such as network telemetry as NetFlow, Zeek, Suricata, and endpoint telemetry from various agents). To the user, VAST offers low-latency access through various APIs, and in particular Apache Arrow for high-bandwidth data sharing with downstream tooling. A flexible plugin API enables additional security-specific use cases on top, such as realtime matching of threat intelligence or mining of asset data for passive inventorization.
