  • Sustainability? No thank you.

  • That's not what I meant, I meant if all organic life that produces oxygen disappeared.

    Photosynthesis is generally so slow at it's job that the current oxygen levels were only built up over hundreds of millions of years. Furthermore, Rubisco, a key enzyme in photosynthesis, surprisingly, is slow and not very good at distinguishing oxygen from carbon dioxide, because it evolved before there was much oxygen on Earth. Therefore a lot of oxygen was produced at the beginning, most of the oxygen we have today in fact, and then not very much thereafter.

    Additionally, the Earth's oxygen levels stay stable due to the release of oxygen trapped in minerals. Over those hundreds of millions of years, they absorbed it. This absorption and release has kept levels stable for well beyond our existence.

    At least that's what I got from the PBS video. If you don't agree, go argue with them, I'm no expert. I'm just forwarding what I learned.

  • I just thought it was an interesting video that challenges what I previously understood about one specific thing 😅 I'm not advocating against the environment, neither is the video, that'd be terrible for many reasons. It's just that the video is from PBS and seems pretty evidence based in why photosynthesis is quite terrible at converting CO2 to oxygen due to the shortcomings of the enzyme Rubisco and how we could improve that. Nothing more than that. Give it a watch, it's not some anti-environment conspiracy video

  • I love nature, but interestingly apparently photosynthesis doesn't actually contribute all that much oxygen and Earth's levels would stay stable for millions of years if all organic matter disappeared. We'd have many, many other problems, but not that one specifically:

  • Giving up control bit by bit

  • I've seen Electron based apps do this sometimes. GitHub Desktop, for instance

  • Giving up control bit by bit

    Jump

  • Until an app decides to install in the hidden AppData folder with the confusing sub-folder names, or even the root of the user folder, or god forbid in a folder in the root of the C drive

  • Librarians in UK increasingly asked to remove books, as influence of US pressure groups spreads

    Jump

  • Just as they say they do not want Sharia law in the UK, we should not support the spread of other extremist religious laws

  • Why doesn't phones numbers have a "DNS" server so we can just type in words like we do with the internet?

    Jump

  • In the first place? We kinda did to begin with, you would phone the operator and say the name of who you wanted to phone.

    Introducing phone numbers simplified this, given the operator would have to know or lookup their name, and allowed for the future introduction of automated systems. Such systems were analogue and DNS was far more advanced than them. I guess the telephone becomes so widely used and integrated under that system that it still uses a similar interface today, albeit with a cluster of different modernised interconnected backends

  • UK could avoid US tariffs that the ‘atrocity’ EU is facing because Starmer has been ‘nice’, Trump suggests

    Jump

  • The UK and US have pretty balanced trading, both reprting surpluses. Isn't that the real reason? Tariffs would be really stupid here

  • Justices take up case on right to sue over mistaken SWAT raid.

    Jump

  • Do Americans really have a right to bear arms? It's technically legal, but if police can murder you and get away with it when they catch you with a gun, that sounds like the consequences are a possible defacto death sentence.

    They only sometimes murder you for it. But there's plenty laws where I'm from that are only sometimes enforced when the police catch you, and not by death.

  • Democrat moves to clarify the 22nd Amendment after Trump refers to running for third term

    Jump

  • Ah, but what if he simply gets rid of democratic elections, then he needn't worry about the issue of being elected more than twice

  • Will the .io domain cease to exist? | Tuta

    Jump

  • Really not looking forward to the idea of github.io links all becoming dead. So many repos with documentation at a github.io URL, with those links spread all across plaintext files and Stack Overflow and forums

  • Russia submarines and naval ships cross into buffer zone off Alaska, U.S. Coast Guard says

  • To avoid sea ice, they entered an area they are legally allowed to enter... okay

  • The UK section of my local supermarket is taking the piss

    Jump

  • In British supermarkets, they often don't even put the beans on shelves. Instead they have stacked palettes of them, because they need to restock so often it'd be inefficient to have to unpack and shelve them.

  • Toilet-specific plungers get the job done faster with way less effort and mess

    Jump

  • Are you American though? Here in the UK, nobody really owns a plunger and they don't need to, the plumbing is different, it doesn't clog. Do need to own a toilet brush though, to wipe off the skidmarks, which is more rare in the US.

  • What bizarre misconceptions do people have about your field?

    Jump

  • Haha, most people here do tech it seems. Well, me too.

    People seem to think I'd be good at maths and my entire job is like maths. I'm not and I don't view it that way. There's a lot of problem solving and engineering, but I find it very creative and expressive

  • Used to do this to my rule all the time

    Jump

  • I always see comments like these online, but they seem kind of absurd to me, coming from a country where it's not only totally common to walk dogs off-leash, but completely legal. There's really very few incidents of dogs darting into the streets here, and actually half the ones I've ever seen have been dogs on a lead anyway. A well trained dog doesn't do that.

  • Oh that makes sense. I didn't consider it might be treated as a char

  • "1" + 2 === "12" is not unique to JS (sans the requirement for the third equals sign), it's a common feature of multiple strongly typed languages. imho it's fine.

    EDIT: I did some testing:

    What it works in:

    • JS
    • TS
    • Java
    • C#
    • C++
    • Kotlin
    • Groovy
    • Scala
    • PowerShell

    What produces a number, instead of a string:

    • PHP
    • SQL
    • Perl
    • VB
    • Lua

    What it doesn't work in:

    • R
    • C
    • Go
    • Swift
    • Rust
    • Python
    • Pascal
    • Ruby
    • Objective C
    • Julia
    • Fortran
    • Ada
    • Dart
    • D
    • Elixir

    And MATLAB appears to produce 51, wtf idk
