Is it using the Barcode Detection API for browsers that support it natively?

i’ve yet to witness a project without “!important” scattered throughout the codebase.
I guess that means I feel the level of expectation is in the name.
Explain the differences in the following to a new developer:
something - a regular variable
$something - just another regular variable with a fancy char
#something - now that’s a private variable
!something - this is… uhm… a regular variable cast to… eh… boolean, then inverted…
~something - type cast blah blah bit flipping magic
!!something - same as !something except inverted again, because using Boolean(something) is not 1337
//something - a comment
Yeah… personally, I much prefer the more explicit ways to write code. it’s cryptic enough as it is, why make it harder for your peers
What I immediately noticed looking at the README, is that the communication is centered around you and your values, rather than on the end-user:
You mention why you created it, not what it enables the user to do. You use Linux-lingo, like “free (speech and beer)” which many users are unfamiliar with and don’t know why they should care. Your installation instructions make it hard for users to pick which one they should choose. There are no Mac binaries, but Macs are wide-spread among developers. Windows binaries mention “x64”, which is very technical and might scare users away.
The Ubuntu screenshots make it look like “Linux only”. You could replace it with a Windows or Mac screenshot, to get people to understand it works on their platform.
You could still keep this technical (and potentially alienating) language in your documentation, but simplifying the README to make it easier for the 90% of your potential audience could make it more popular.
You mentioned in this thread that some people don’t want Electron. That’s true, and it’s a great USP for those that require it, but personally I would avoid assuming that it’s the USP that convinces the masses.
If a project took only 1 month, I’d be very cautious with calling it easier to work with, because it likely means fewer tests (leading to lower velocity long-term) and fewer hours spent by other developers trying to understand it, and giving feedback on how to improve legibility.
Creating something quickly can be really important in specific contexts, but actually KEEPING something flexible to work with, hard to break, and easy to understand is more important when dealing with software that’s supposed to last over many developers and a long period of time.
Maintaining velocity requires you to spend more time on keeping the code base healthy.
I find the notion of being a fast programmer irrelevant in a business-context. Because there I think it’s more valuable to be a programmer that can ensure business goals are met on time, ensuring the correct problems are solved, ensuring contracts aren’t broken, while still keeping the code base professional (i.e. well-tested, clean, consistent).
Being a fast programmer is great and all, but being reliable is the more favorable trait if I had to pick one. Both require huge amounts of active training.
I find JavaScript to be very accessible, because it can be run in the browser. No extra tools required and if you want, you can get immediate visual feedback by, for example, manipulating the DOM
The biggest takeaway for me was: make the interviewee feel comfortable by letting them talk freely about subjects they feel passionate about, and the interviewer should ask genuine and good questions by properly researching the interviewee beforehand.
