Ask HN: Who is hiring? (September 2023)
- 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.

Why TileDB as a Vector Database
Stavros from TileDB here (Founder and CEO). I thought of requesting some feedback from the community on this blog. It was only natural for a multi-dimensional array database like TileDB to offer vector (i.e., 1D array) search capabilities. But the team managed to do it very well and the results surprised us. We are just getting started in this domain and a lot of new algorithms and features are coming up, but the sooner we get feedback the better.

Why isn’t there a decent file format for tabular data?
Hi folks, Stavros from TileDB here. Here are my two cents on tabular data. TileDB (Embedded) is a very serious competitor to Parquet, the only other sane choice IMO when it comes to storing large volumes of tabular data (especially when combined with Arrow). Admittedly, we haven’t been advertising TileDB’s tabular capabilities, but that’s only because we were busy with much more challenging applications, such as genomics (population and single-cell), LiDAR, imaging and other very convoluted (from a data format perspective) domains.
Similar to Parquet:
* TileDB is columnar and comes with a lot of compressors, checksum and encryption filters.
* TileDB is built in C++ with multi-threading and vectorization in mind
* TileDB integrates with Arrow, using zero-copy techniques
* TileDB has numerous optimized APIs (C, C++, C#, Python, R, Java, Go)
* TileDB pushes compute down to storage, similar to what Arrow does
Better than Parquet:
* TileDB is multi-dimensional, allowing rapid multi-column conditions
* TileDB builds versioning and time-traveling into the format (no need for Delta Lake, Iceberg, etc)
* TileDB allows for lock-free parallel writes / parallel reads with ACID properties (no need for Delta Lake, Iceberg, etc)
* TileDB can handle more than tables, for example n-dimensional dense arrays (e.g., for imaging, video, etc)
Useful links:
* Github repo (https://github.com/TileDB-Inc/TileDB)
* TileDB Embedded overview (https://tiledb.com/products/tiledb-embedded/)
* Docs (https://docs.tiledb.com/)
* Webinar on why arrays as a universal data model (https://tiledb.com/blog/why-arrays-as-a-universal-data-model)
Happy to hear everyone’s thoughts.

Seeking options for multidimensional data storage
It could be worth checking out TileDB: https://github.com/TileDB-Inc/TileDB The entire system, down to the data format itself, is optimized around storing multi-dimensional arrays. It also supports timestamps and real numbers as dimensions, which could be handy given your example data. [Full disclosure: I currently work for TileDB.]

how to work with .xlsx files?
ExcelJS and XLSX (SheetJS) are great libraries to work with XLSX files. The former I've found a bit easier to work with but less efficient in general.
-
What kind of Programmer / language should I be looking for?
Sure. I manipulate excel files programatically in the browser all the time. I don't really understand your exact workflow, but I use Javascript with xlsx and React.

React App Won't Read xlsx File
Looking at the xlsx documentation, to parse files in the browser, rather than readFile, you use read, which is designed to parse binary data directly, rather than read from disk. There are a bunch of different formats if you go to the XLSX NPM page and scroll down to "Acquiring and Extracting Data". Importantly, it seems the data must already be serialized, so a Blob won't work, but we can work with that.

We compete with GitHub. Bing does not show our website
Last year, Bing and Edge erroneously flagged our website https://sheetjs.com/ as "dangerous": https://i.imgur.com/BvA3zrk.png
At the time, there was no "Safety Report" to indicate why Bing thought it was dangerous. The report page linked to https://www.bing.com/toolbox/bing-site-safety?url=https%3a%2... and it said "That web page doesn't exist"
To fix it, we had to register with "Bing Webmaster Tools" (https://www.bing.com/webmasters/about) and raise a support ticket.
Within a few days, the issue "resolved itself". It's possible that raising a ticket forced some automatic refresh of the indexed data for the domain.
