Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Vector: A high-performance observability data pipeline
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.

Ask HN: Who is hiring? (March 2024)
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:

Pql, a pipelined query language that compiles to SQL (written in Go)
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.

Cisco Acquires Splunk
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.

Parallel Grouped Aggregation in DuckDB
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.)

C++ Jobs - Q4 2021
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.

Understand Attestations! Ultimate Guide📚
You can create an attestation based on an existing schema or create your own. Schemas define the format in which attestations will be made, and in this case, we will use the Is Human schema to attest that the owner of a certain address is human. For this example, you only need to connect your Metamask wallet (or any wallet) to Scroll Sepolia, then enter the address you want to attest and click Make attestation. You can choose whether you want the off-chain attestation, i.e., free, obtained only by signing a transaction. Alternatively, you can choose to make it on-chain and pay for the transaction to make it public and connect it to smart contract logic. In this case, you will need to obtain funds in Scroll Sepolia through a Scroll Sepolia Faucet.

Fe or Solidity, which is better?
For this tutorial you will need Metamask or other wallet of your choice, with Scroll Sepolia funds that you can get from a Sepolia faucet and then bridge them to L2 using the Scroll Sepolia bridge. Alternatively, you can use a Scroll Sepolia Faucet to get funds directly on L2.

Why Bother with uBlock Being Blocked in Chrome? Time to Switch to Firefox
> I get a 3-5 sec lag on launch [0] as it prepares the browser to block ads.
uBO is typically ready in a fraction of second, so "3-5 sec" is not normal. In Firefox all extensions sit in the same process, so it's possible another extension is preventing uBO to be ready in a timely manner, this has happened[1].
