I gave two examples of secondary sources, but what I’m really getting at here is that the numbers and noise are so, so high now (not to mention staffing firm fronts and foreign actors) that I usually need more signal than a solid-looking resume before investing even 30’ in a screening call.

TileDB is the database designed for discovery, built to organize, structure, and analyze any data. Our solutions for single-cell and population genomics are used by major pharmaceutical companies and research institutes, and power large public data collections such as the Cellxgene Discover Census. We are actively hiring for several roles building our unified data catalog, scalable computation, and interactive analysis platform.

- Infrastructure Engineer: Kubernetes, Terraform, Argo, Grafana, Prometheus, CloudWatch, GitOps; Golang, Python, C++, or Rust (GMT -8 to -4).

- Frontend/UI developer: Typescript, React; experience with high-performance/high-volume data and visualization applications. (GMT -8 to +1)

We are fully-remote, with optional co-working hubs in Cambridge, MA, New York, NY, and Athens, Greece. Apply today at https://ats.rippling.com/tiledb-careers/jobs or reach out directly (email in profile).

TileDB has recently announced a $34 million Series B fund-raise and is actively hiring for engineers across a range of roles (SRE, backend/distributed systems, database internals, and more). You will have the opportunity to work on innovative technology that creates impact for challenging problems in genomics, geospatial, machine learning, distributed systems, and many other areas.

TileDB Cloud is the modern database, allowing developers and scientists to capture, analyze, and share any data with any tool. We build on a broad foundation of open source, maintaining the TileDB storage engine, libraries for genomics (single-cell and population), geospatial (raster, point clouds, and more), a TileDB visualization engine extending Babylon.js, and much more ([github.com/TileDB-Inc/TileDB](http://github.com/TileDB-Inc/TileDB))

With TileDB, all data — tables, genomics, images, videos, location, time-series — is captured as multi-dimensional arrays. To supercharge this data, TileDB Cloud implements a serverless infrastructure delivering query execution, access control, data and code sharing, and distributed computing at global scale — eliminating cluster management, minimizing TCO, and promoting scientific collaboration and reproducibility.

TileDB is the database for complex data, allowing data scientists, researchers, and analysts to access, analyze, and share any data with any tool at global scale. Here are some active projects you could work on:

- vector search, utilizing TileDB and TileDB Cloud for seamless scaling: https://tiledb.com/blog/why-tiledb-as-a-vector-database (library: https://github.com/TileDB-Inc/TileDB-Vector-Search)

- single cell genomics: in collaboration with the Chan-Zuckerberg Initiative, we recently released TileDB-SOMA for single cell data, with APIs for both Python and R built around a common storage specification: https://tiledb.com/blog/tiledb-101-single-cell

With TileDB, all data — tables, genomics, images, videos, location, time-series — across multiple domains is captured as multi-dimensional arrays. TileDB Cloud implements a totally serverless infrastructure and delivers access control, easier data and code sharing and distributed computing at global scale, eliminating cluster management, minimizing TCO and promoting scientific collaboration and reproducibility.

TileDB is the database for complex data, allowing data scientists, researchers, and analysts to access, analyze, and share any data with any tool at global scale. We have just launched a vector search library leveraging TileDB and TileDB Cloud for powerful local search and seamless scaling to multi-modal organizational datasets and batched computation: https://tiledb.com/blog/why-tiledb-as-a-vector-database (library: https://github.com/TileDB-Inc/TileDB-Vector-Search)

With TileDB, all data — tables, genomics, images, videos, location, time-series — across multiple domains is captured as multi-dimensional arrays. Our vector search library and other offerings are designed to empower these datasets with extreme interoperability via numerous APIs and tool integrations across the data science ecosystem, eliminating the hassles and inefficiencies of data conversion. TileDB Cloud implements a totally serverless infrastructure and delivers access control, easier data and code sharing and distributed computing at global scale, eliminating cluster management, minimizing TCO and promoting scientific collaboration and reproducibility. TileDB, Inc. was spun out of MIT and Intel Labs in May 2017 and is backed by Two Bear Capital, Nexus Venture Partners, Uncorrelated Ventures, Intel Capital and Big Pi. Recent press-release for the 1.0 release of our Single-Cell API, supporting Python, C++, and R with AnnData and Seurat: https://www.businesswire.com/news/home/20230328005380/en/Til...

Yes, Cxx: https://github.com/JuliaInterop/Cxx.jl -- it uses Clang to generate JIT'd interop thunks, and does neat things to enable that, like cross-language type inference and inlining (in addition to the REPL).

CxxWrap is a different thing, which AFAIK has been actively maintained for > 5 years now: https://github.com/JuliaInterop/CxxWrap.jl

It is similar to Boost.Python/pybind11/nanobind: bindings are written in C++ and compiled ahead of time into a module that defines Julia entrypoints. Those entrypoints take care of signature selection, translation to/from Julia objects, and lifetime bookkeeping.

I don't see many details about the sandboxing/hermetic build story in the docs, and in particular whether it is supported at all on Linux or Windows (the only mention in the docs is Darwin).

It's a good sign that the Conan integration PR [2] was warmly received (if not merged, yet). I would hope that the system is extensible enough to allow hooking in other dependency managers like vcpkg. Using an external PM loses some of the benefits, but it also dramatically reduces the level of effort for initial adoption. I think bazel suffered from the early difficulties integrating with other systems, although IIUC rules_foreign_cc is much better now. If I'm following the code/examples correctly, Buck2 supports C++ out of the box, but I can't quite tell if/how it would integrate with CMake or others in the way that rules_foreign_cc does.

(one of the major drawbacks of vcpkg is that it can't do parallel dependency builds [3]. If Buck2 was able to consume a vcpkg dependency tree and build it in parallel, that would be a very attractive prospect -- wishcasting here)

> Not yet. The main problem is that RuneScape requires low level network connections primitives (sockets)

So, I'm guessing the same applies to the C++ version?

vcpkg strongly recommends using it as a submodule. But at least that would only be one submodule.

    Really annoyed by the borrow checker? Use immutable data structures
    ... This is especially helpful when you need to write pure code similar to that seen in Haskell, OCaml, or other languages.

I suspect Rust does not implement as many FP-oriented optimizations as GHC, so this approach might hit performance dropoffs earlier. But it should still be more than fast enough for learning/toy datasets.

This makes more sense in light of a comment by the author in a previous discussion about C ABIs [1]:

> Virgil compiles to tiny native binaries and runs in user space on three different platforms without a lick of C code, and runs on Wasm and the JVM to boot. [...] No C ABI considerations over here.

I use `#%%` code blocks in the interactive window for this purpose: https://code.visualstudio.com/docs/python/jupyter-support-py

This allows a normal editor workflow, interactive execution, and linear history of executed cells. But the code blocks can still be executed top-to-bottom and exported as a clean notebook for sharing purposes.
