This doesn't measure CO2 levels. It measures volatile organic compounds and calculates the amount of CO2 that would cause the same greenhouse effect.

>The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use.

Java/.NET/C++/etc. people don’t have the urge to publish every other line of code they deem “useful”. They also don’t have the urge to import said one-liners when writing a helper method in 15 seconds is perfectly adequate.

If only there was some standard format to interchange structured data over pipes, other than plain text delimited with various (incompatible) combinations of whitespaces, using various (incompatible) escaping schemes.

False. Writing a waterfall-style “spec” on paper has nothing to do with formal methods.

Would you notice if that URL was “raw.githubusercontent.someotherdomain.com” instead of “raw.githubusercontent.com”?

I’m pretty sure at least 50% would merrily copy & paste it in their shell.

They’ve added some Apple-specific extensions to SMB, which can result in suboptimal performance when browsing non-Apple hosts.

Mind you, the current recommended file sharing protocol on macOS is SMB. (since Apple have deprecated AFP)

Re:Projecting Unicode to ASCII on Thursday January 10, 2019 @04:20PM (#18878316)
It’s part of uconv’s transform rule syntax:

Re:Projecting Unicode to ASCII on Thursday January 10, 2019 @02:38PM (#18877269)
How would that help when e.g. copying files from a Linux server to macOS via Samba? Mind you, the filenames can contain both NFC, NFD or the mixture of the two.
Re:Projecting Unicode to ASCII on Thursday January 10, 2019 @11:05AM (#18874826)
I use this transform chain for asciifying filenames (ridiculous as it is, in 2019 we still can't sync unicode filenames between different OSs):

    uconv -x ':: Any-Latin; :: Latin-ASCII; [:^ASCII:] > \_'
Explanation:

    Any-Latin
Transliterates from non-latin scripts to latin script (e.g. "γραφὴν" --> "graphḕn").

    Latin-ASCII
Tries to asciify characters as much as possible by discarding accents, splitting ligatures, replacing Unicode quotes with regular quotes, © --> (C), etc.

    [:^ASCII:] > \_
Replaces any remaining non-ASCII characters with an underscore.
Laptops with preinstalled Windows also have a tremendous amount of crapware from various vendors. Trial versions of antivirus software, system "optimizing" apps, sometimes outright spyware too.

Thankfully Mac users don't have to put up with this kind of consumer-hostile bullshit.

I’d say this is because the concept of a “stare down” is instictive to us primates (or even mammals in general). That is, asserting dominance via staring at others is something we’re born with, and for good reason: our ancestors’ survival hinged on this when being confronted with someone bigger/stronger. That’s why you look down when you’re anxious or ashamed. Canines and felines do the same.

So it’s just natural that people subconsciously transfer this dominance-via-staring to inanimate objects as well, because it comes from a very ancient mammalian instinct.
