Do you have more details on the Firefox problem?
I have a WebRTC project that is currently in standby (priorities changed) and one issue that I have not been able to troubleshoot was an inability to send audio from Firefox while it somehow worked on Chrome.
It works fine in Firefox (send and receive) as long as you don't need to play on multiple output devices. Currently you can enable a feature flag, use enumerateDevices() and play audio files on specific devices, but you can't hook up WebRTC streams to the devices.
Alex Chronopoulos: "We keep it off because it does not work for everything. It works when we playback a file but not for webaudio or WebRTC. We want to add those too and we keep it off till then."
Miller (mlr) is now my goto tool for csv/tsv manipulation.
I've used it from time to time during the past year and it's been a joy to use.
I must admit that I did not try any other tool for the purpose so I don't know how it compares.
I did an internship last year which consisted in writing unit tests for a raytracing library that was among other things - I was told - used to determine if buildings were on paper getting enough sunlight according to european standards.
I'm not sure whether they were talking about EU regulations or about the regulations of specific european countries.
I think there are at least two separate issues here; some countries have health and safety laws requiring natural light, while others require natural light in newly-built offices (as a condition of planning etc). Can you build an office in London these days that doesn't have natural light in the main spaces? I'd be sceptical.
Is it an old building? There are some basement offices in London, and presumably other countries, with either no windows or pointlessly small/ineffective ones (like those little glass blocks you see on the pavement occasionally). I wonder if light regulations would have to have exclusions for old buildings that are impractical to change (a bit like minimum platform widths at train stations don't apply to some old stations).
I don't know how it compares to xsv, but you might be interested in Miller/mlr (http://johnkerl.org/miller/doc/index.html), I've used it because csvkit was too slow for what I needed to do and was pleasantly surprised by its features.
That's funny because I am a native French speaker and I find German to be a very pleasing language to speak out loud. The sonorities are oddly satisfying to me.
Please note that I am nowhere near fluent in German. It just feels great, especially the way words can agglutinate to form comically long words, while still transporting meaning.
