@Peilonrayz "... and the pièce de résistance is finding you already had the software installed..." that could be like other people and tabs.
FYI I installed VCPKG yesterday and now I can't find it.
@pacmaninbw I would assume so ;) Interestingly I upgraded my RAM because having the amount of tabs I like was starting to be a little problem for my poor laptop D:
@pacmaninbw Yeah that can be a pain, I had lots of problems with Python because of that. I'm now strictly using WSL, Window Terminal and VS code when developing on my laptop. Having pacman on Windows is a dream come true ngl

@Mast Wow yeah, what a high energy talk. I remember now how long it's been since I learnt to debug. I still remember rage-quitting programming cause I didn't understand self either... Some good info in the talk, but the talk could easily be 20 minutes

Q: Partial Function composability in Haskell

tangyBelow is my solution for the CTFP chapter 4 challenges which essentially involves composing partial functions(that don't have defined outputs for all possible inputs i.e. returning a Maybe). The challenge is to implement composition, identity(to satisfy category requirements) and try it out with ...

@Peilonrayz A week or two ago I had to install Internet Explorer 11 on Windows 10 machine. Download the installer, install the thing and try to run it. No joy, the relevant folders are there but main executable iexplore still missing. Reboot. No joy. Install again. Goes a lot faster this time. Reboot. No joy. What the heck...
Guess what?
It's hidden under Windows Features now.
Install it from there, works.
But the official download page won't tell you that.
So, yea, I'm familiar with the feeling :-)
Q: Data state filter on toggle by categories

ErwinHere is a simple react app that will list some dummy data and can be filtered by categories (in this case, by user ID) by toggling the button on/off. FilterBtn.js import React, { useContext, useState } from "react"; import DataContext from "../../context/dataContext"; import "./FilterBtn.css"; c...

@pacmaninbw Firefox (and the other brands probably do too) has tab suggestions. When I type '2nd' in a new tab, it will give me a shortcut to an already open tab (The 2nd Monitor) and switch to that instead of opening it again.

The user passes and identifier for Y as a key or an index (negative or positive). Any improvement is fine as an answer. Co...
