That model still works for streaming. You have a central source stream only to the distributed edge locations, then have clients only stream from their local edge location. Even if one region is overwhelmed, the rest can still work. Load on

Humans have a massive capacity to vary energy use. Highly trained endurance athletes like professional road cyclists and triathletes can average 3x or more the typical daily energy expenditure of a non-athlete on a long term basis. The idea

I'm really happy to see this, I love using the ipython console and notebooks, and while the deno repl was ok, it's not as good. I wonder if Deno can be used with https://quarto.org/ now?

I'd be interested in knowing more about your API use. Are you using the official 3rd party API or one of their internal APIs used by their own web front-end? It's a good idea for a project like this. One bit of feedback is that it

Thanks! That's right, it's pure Python. It's certainly a lot slower than C or Rust, but I've not done any benchmarking to get a good sense. I believe Deno have a Rust implementation which they use, so in principle a Pyth

MappingProxyType is another handy one. It wraps a regular dict/Mapping to create a read-only live view of the underlying dict. You can use it to expose a dict that can't be modified, but doesn't need copying. https:/&#x

> Is this tool not an additional dependency? It is, but if you already have bash, adding another shell script isn't much of a jump. e.g. I'd feel OK about committing jb to another repo for use from a .envrc file to set up an en

jc has many parsers for the specific output format of various programs, it can automatically create a JSON object structure using its knowledge of each format. jb doesn't have high-level knowledge of other formats, it can read from com

That is pretty cool, and I wish such features were common in regular UNIX shells. For good measure, this is how you might do the same with jb: $ jb Hello=world array:number[]@<(seq 10) object:json@<(date=$(date -Iseconds) jb @da

Two main situations I think. The first is just interactive use in any shell to encode ad-hoc JSON. If you have a next-gen shell which can handle structured data directly, then you probably don't need it. Second is situations where you&

Good question! Yep, jb exits with non-zero: $ jb size:number=oops; echo $? json.encode_number(): not all inputs are numbers: 'oops' json(): Could not encode the value of argument 'size:number=oops' as a &#x

How did you guess my password?!?! This is just the kind of use case I had in mind. Something I've considered is publishing a mini version with only the json.encode_string function, as that's enough to create an array of JSON-encod

There is, the earliest version I've tested with is 4.4.19, but ideally a 5.x version. 3 certainly won't work I'm afraid. If you use homebrew on Mac it's a good way to get the latest bash.

Thank you, that's high praise! I learnt a lot about bash writing this, but I've also not looked at the code in a few months, and it's already starting to look quite intimidating! I definitely like the idea of a goland/ru

Powershell has the upper hand here! Still, bash can try to keep up using json.bash. :) $ source json.bash $ declare -A greeting=([Hello]=World) $ json ...@greeting:{} {"Hello":"World"} ... is splatti

If it helps, there's a little example of using the bash API with bash variables/arrays, should give you an idea of how it could be to use: https://github.com/h4l/json.bash/blob/main/examples&#x2

Thanks for giving it a try and your feedback. I agree, the array splitting is a bit fiddly. It is actually possible to pass JSON directly, you use the :json type on the argument: $ jb dependencies:json='["Bash","Gr

I did find it quite satisfying to coerce bash into doing this while maintaining decent performance. I definitely came to appreciate some aspects of bash more from this, but it's so easy to shoot yourself in the foot! If I started from

Glad to hear, this was something I wanted to make reliable, ergonomic and intuitive. I figured a lot of languages use `: type` to declare types. The same using jo would be like this, which I find harder to type and remember: jo -- -s id

It's nice to have compact single-file dependencies like this! I like the look of your assertions (checking out, err & status). I definitely found myself writing my own assertions to get understandable errors.

Thanks!

As well as anyone's general thoughts/experiences, I'd appreciate opinions on the error handling mechanism jb uses to detect errors in upstream jb processes that jb is reading from. Normally, detecting errors on the other end

In the UK our native squirrels are red, but they're almost extinct because North American grey squirrels out-compete them.

You've probably accumulated a lot of relevant html knowledge which will help you. I presume you have some css-related projects/tasks in mind that you'd like to be able to tackle yourself. I would pick one of those and jump in

I would probably start by opening the browser dev tools on web pages and use inspect element to see how an element in the page has been made to look the way it is. You can edit properties to see what effect they have when changed. The domai

I can imagine it's very hard if you don't know how to use browser dev tools to see the style properties being applied to elements.

Looks like a handy resource you're building here, thanks for this. FYI the category link right under the title links to a different category to the link below, and the first link only contains one post.
