aaaaaaaaaab··on Show HN: I wanted to measure CO2 in my office, so I build a C++ WebServer/App
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.

aaaaaaaaaab··on Our Software Dependency Problem
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.
aaaaaaaaaab··on CompCert – A formally verified C compiler
Fully Countering Trusting Trust through Diverse Double-Compiling

aaaaaaaaaab··on For the Love of Pipes
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.
aaaaaaaaaab··on Why Don't People Use Formal Methods?
False. Writing a waterfall-style “spec” on paper has nothing to do with formal methods.
aaaaaaaaaab··on If 5G Is So Important, Why Isn’t It Secure?
Autonomous cars need internet access to display relevant ads to the passengers.

aaaaaaaaaab··on RE:DOM – Tiny turboboosted JavaScript library for creating user interfaces
>closer to the metal

Lol. Sure! Just like how I get closer to the Earth’s core if I’m sitting on the floor instead of my chair.

aaaaaaaaaab··on My Parents Are Flat Earthers
I remember stumbling upon the Flat Earth Society back around 2003. I was convinced it was one of those elaborate ironic jokes/hoaxes that we used to have back then (bonsai kitten, World Jump Day, etc.)
aaaaaaaaaab··on What People Say Before They Die
What made you change your mind?
aaaaaaaaaab··on Bash 5.0 released
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.

aaaaaaaaaab··on Nuclear – Popcorn Time for music
Ah, an Electron app... :)

Something tells me it doesn't support gapless playback. (I might be wrong tho)

aaaaaaaaaab··on Deep packet inspection is dead, and here's why (2017)
Ok, I’ll draw the logo!
aaaaaaaaaab··on DIB Guide: Detecting Agile BS (2018) [pdf]
So that’s why all network gear needs to be power-cycled at least weekly to function correctly!
aaaaaaaaaab··on Avoiding a transit of the United States
>You can't lie

Demonstrably false.

aaaaaaaaaab··on Netflix to raise prices by 13% to 18%
>What are those services doing, exactly?

Probably generating logs about themselves.

aaaaaaaaaab··on 35-year-old vulnerability discovered in scp
It’s easy to fix. Just rewrite scp in Rust.
aaaaaaaaaab··on Android vendors, don’t kill my app
>I don’t think you could implement a tracking socket masquerading as a background download

The Facebook app used to play a silent audio track to stay active in the background, until they got called out: https://www.reddit.com/r/iphone/comments/3opxhm/facebook_app...

Terrence Tao also stutters.
aaaaaaaaaab··on Language Server Protocol implementation for Swift and C-based languages
They’ve added some Apple-specific extensions to SMB, which can result in suboptimal performance when browsing non-Apple hosts.

aaaaaaaaaab··on Language Server Protocol implementation for Swift and C-based languages
>Apple implementing a spec designed by Microsoft!?!?!

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

aaaaaaaaaab··on Projecting Unicode to ASCII
It’s part of uconv’s transform rule syntax:

>Each transform rule consists of two colons followed by a transform name.

aaaaaaaaaab··on Projecting Unicode to ASCII
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.
aaaaaaaaaab··on Projecting Unicode to ASCII
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.
aaaaaaaaaab··on Samsung Phone Users Perturbed to Find They Can't Delete Facebook
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.

aaaaaaaaaab··on Implicit model of other people’s visual attention as an invisible beam
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.

aaaaaaaaaab··on Marc Andreessen: VR will be 1,000 times bigger than AR
Hmmm.

1000 * 0 = 0

T-h-r-e-e? How is this even possible?
