@matloff @KWittfogel In terms of having most of the language written in Julia. With code analysis in R it's such a barrier to get to C code. Then there are other things like the type union for missing values https://t.co/fLmV0A9DpF that are nice for data analysis.

Debuggers are so nice. Blog post: introduction to #debugging in #julialang with inspiration from @matloff

@matloff @KWittfogel Most of the Julia language design I've seen seems well thought out.

[Clark Fitzgerald @clarkfitzg]

@matloff I'm just starting out.

[Clark Fitzgerald @clarkfitzg]

Everything mysteriously broke when I copied and pasted some code that had a Unicode hyphen (8208) for a command line flag instead of an ASCII dash -. Argh. 😬

@shoyer @GoogleAI Working with @shoyer on scientific visualization was the best internship I've had.

TIL about GNU parallel. Similar API to xargs. https://t.co/1PgStEYY8S

Happy about everything that tmux can do on a SLURM cluster. Try
srun --pty bash
to open a shell in a compute node to experiment a bit so you don't tie up the head node.

@hfmuehleisen @jstatsoft @bedatadriven @mj_kallen I was just reading your preprint last month :)

I left employment at Anaconda Inc. last week.

I start employment at NVIDIA next month.

Surprisingly little about my work will change.

Here are 6k accepted #rstats answers that use/mention #rdatatable where the question was not about data.table. (Distinct from the 8k questions tagged data.table.) Would love to see some data science on this to help guide the project. Anyone interested? https://t.co/8hSi8Aqeuw

[Clark Fitzgerald @clarkfitzg]

The web based UI seems great too: https://t.co/WTzFu8CMou

https://t.co/EeTKzvc4e7 offers their entire database as a Postgres dump. Materializes to ~1TB! #BigData #opendata https://t.co/yX9gG5Qy1S

The caching in #rstats bigmemory package worked perfectly for an application that moved through small neighborhoods of a large matrix. Nice work by @kaneplusplus et. al. https://t.co/qewXndkm4w

I'm pleased to announce xarray v0.11:
https://t.co/2gtHloLjEm

This release includes:
- file-storage refactor for performance with @dask_dev
- better support for calendars used in climate science
- lots of other miscellaneous API clean-ups, bug-fixes and enhancements

Cool use case for #metaprogramming:
Given a table with many equations in text, turn them into functions and call them on observations in another table.
