Fix no wifi on linux mint for old HP laptop

My old HP laptop had a very old wifi card that wasn’t supported out of the box by linux mint, but I was able to install the necessary drivers with the following code

sudo apt install broadcom-sta-dkms
sudo apt-get install broadcom-sta-dkms

Picking ionic back up

If you’re on a fresh macOS install, you’ll need to first install the necessary components

  1. download NPM installer from their website
  2. sudo npm install -f @ionic/cli
  3. sudo npm i -g cordova
  4. sudo gem install cocoapods

OK, so it’s been a while and you have to pick back up from where you last left off with your ionic app. He’s how to go about that on Mac with Git.

  1. Pull from Git
  2. Run “npm install” to get all the modules
  3. Run “ionic cordova platform add ios”
  4. Run “ionic cordova prepare” to install plugins
  5. Run “sudo npm i –unsafe-perm -g cordova-res” and “ionic cordova resources” to generate splash and icons

If you need to redo your signing, you can follow these steps

  1. Select a development team
  2. If you invalid errors, make sure your system clock has the correct date

Hopefully that did the trick and you’re ready to go, I’ll add any errors and fixes I come across to the end of the article, but here’s how to go about testing.

Emulator testing:

  1. Just run ‘ ionic cordova emulate ios  -l — –buildFlag=”-UseModernBuildSystem=0″ ‘ to start it up in the emulator

Ad hoc Device testing:

  1. Open Xcode
  2. Open the iOS project, probably something like “~/Documents/app/platform/ios/App.xcworkspace”
  3. Login to developer account under Xcode>settings>accounts
  4. Select “Generic iOS Device” as device
  5. Choose Product->Build For->Testing
  6. Product->Archive
  7. Click the “Export…” button and choose Development and choose where to export the IPA
  8. Upload the IPA to diawi.com, then install on device


To fix “‘xcodebuild’ requires Xcode” errors

  • Run Xcode from applications directory (make sure to drag and drop the application into the directory)
  • xcode-select –install # Install Command Line Tools if you haven’t already.
  • sudo xcode-select –switch /Library/Developer/CommandLineTools # Enable command line tools
  • sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Fastest way to search an object

Same deal as my previous post, I want to pin down the fastest method to use to search the parameter values of an object in Javascript using https://jsperf.com.  I found 4 different ways to receive the same result, this isn’t an exhaustive list but features some of the most common methods used for searching objects.

Between multiple tests findIndex and find did the best, but find was faster more often then findIndex.
