wttr.in VS ish

#!/bin/bash # Get weather information for a specified location LOCATION="London" curl "http://wttr.in/$LOCATION?format=3"

We’re going to use a free weather API, wttr.in, which gives us weather info just by calling a URL.

locals { url = format("https://wttr.in/%v?%v&format=%v&lang=%v&u=%v", urlencode(var.location), urlencode(var.options), urlencode(var.format), urlencode(var.lang), urlencode(var.units), ) } data "http" "weather" { url = local.url request_headers = { User-Agent = "curl" } } # Now write this to a file (as an example of a resource) resource "local_file" "cache" { filename = "cache.${var.stage}.txt" content = data.http.weather.response_body }

wttr.in is unfortunately not accurate in many cities in the world, check their github issues

The difference with weafetch is that it has its own config file which can just be configured and not touched anymore. When using wttr.in with curl, any custom changes you want to get from the output will need to be typed in everytime.

What about https://wttr.in/ ?

On IOS, there is a emulator called ISH which looks great. I haven't tried personally though, I couldn't afford an iphone. I will be using Termux on android for the rest of the post.

I'm a happy daily iSH [1] user, it's an amazing technical project, but I really pine for the day when `apt get blah` will be a reality, using an app available from the official App Store. Be it a paid or free app. CLI only, or with graphics. For concreteness, let's say a Debian-based distro in your iPhone upon tapping Get on Apple's App Store, independently of your location. It is pretty sad that, if this ever comes to be, it will probably be the result of EU/DOJ forces, not of technological advancements.

When do you see this happening (options are number of years)?

You can run iSH on the device for Linux (somewhat limited)

https://github.com/ish-app/ish

If you're curious, iSH's source is public: https://github.com/ish-app/ish

You're correct that there is no Linux kernel emulation. They went with reimplementation for that. However, the userland is very much emulated x86 binaries. You can even compile your own C code inside iSH and run it. When you syscall, control passes from the threaded code[0] interpreter into the Linux reimplementation.

The reason why they aren't shipping Debian is that the threaded code technique being used as a JIT substitute in both iSH and UTM SE is far too slow to run a full Debian derivative. Believe me, I tried installing Ubuntu on UTM SE and it took literal hours and flattened my iPad battery in the process. iSH uses Alpine Linux because it's very lightweight[1].

As far as I'm aware there's no secret deal with Apple to lock iSH down. The only limitations I've ran into have to do with MySQL, which wants unaligned atomics, which you can't do on ARM64 without compromising the performance of the emulator. I actually had a discussion with the developer of iSH about this and put in a PR to make MySQL stop crashing iSH.

[1] So lightweight it doesn't even ship anything GNU, making it one of the few genuine "Linux distros" with no slash or plus or "I would just like to interject"

That would be iSH, slow but functional Alpine Linux emulation for iOS.

> Just imagine how much more versatile the iPad Pro would be if only you could run Linux VMs on it

After installing https://ish.app for Alpine Linux emulation on iPad, one immediately comes up with use cases, even though it's excruciatingly slow.

Hopefully Apple opens up the imminent M3 iPad Pros to run macOS and Linux VMs.

iSH

They don't "allow" it, but most apps that need background execution just ask permission for geolocation tracking and pretend to use it, for example iSH[1]. There are a few activities that the app can do to prevent itself from being suspended when it goes out of focus, like playing sound, geolocation etc.

Android: install termux, `pkg install openssh`, and preferably run `termux-setup-storage` to give it access to storage folders.

iOS: I think https://ish.app/ ?
