The iOS missed call badge is designed to alert you when you've missed a call. However, sometimes, even after checking the missed calls, the badge remains. This can be due to a minor glitch in the system or sometimes because the 'All' and 'Missed' tabs in the 'Recents' section of the Phone app haven't been toggled.

The Solution:

To get rid of that stubborn missed call badge, follow these easy steps:

1. Tap on the Phone icon on your iPhone's home screen.
2. Once inside the Phone app, tap on 'Recents' at the bottom.
3. At the top of the 'Recents' screen, you'll see two tabs: 'All' and 'Missed'. Tap on them to toggle between the two.
4. Exit the 'Recents' screen.

    • Twitter is a social media platform where users can post short messages called "tweets". Tweets can be positive or negative, and we would like to be able to classify tweets as positive or negative. Here are some examples of positive and negative tweets. Make sure to classify the last tweet correctly. Q: Tweet: "What a beautiful day!" Is this tweet positive or negative? A: positive Q: Tweet: "I hate this class" Is this tweet positive or negative? A: negative Q: Tweet: "I love pockets on jeans" A:
• parts of a prompt
  • A role
  • An instruction/task
  • A question
  • Context
  • Examples (few-shot)
• However, it's generally preferable to place the instruction last to ensure the model focuses on executing the task rather than extending the context

After upgrading to macOS Ventura, I tried to run git from Terminal but it kept giving me the following error:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun.

Solution

Open Terminal, and run the following:

xcode-select --install

This will pop a dialogue box, Select "Install", and it will download and install the Command Line Tools package and fix the problem. (The popped Window may be behind other windows.)

You do not need Xcode, you can install only the Command Line Tools here, it is about 130 MB (600 MB as of Xcode v14.1).

If the above alone doesn't do it, then also run:

sudo xcode-select --reset

It's possible you may need to accept Xcode license too.

sudo xcodebuild -license accept

After installing luxon with npm install luxon --save, I wrote the below function.

import { DateTime } from 'luxon'

daysToAccountExpiration(userCreationDate) {
    const created = DateTime.fromISO(userCreationDate)
    const expiration = created.plus({ days: 7 })
    const daysLeft = Math.floor(expiration.diff(DateTime.now(), ['days']).as('days'))
    return daysLeft
  }

Run the above command with nvm configuration to switch to the correct node version for a project.

I had a JSON file where I wanted to delete every line containing the line code where every value of code was different.

// Example json
[
  {
    "name": "United Kingdom",
    "dial_code": "+44",
    "code": "GB"
  },
  {
    "name": "United States",
    "dial_code": "+1",
    "code": "US"
  },
  {
    "name": "Uruguay",
    "dial_code": "+598",
    "code": "UY"
  },
  {
    "name": "Uzbekistan",
    "dial_code": "+998",
    "code": "UZ"
  },
  {
    "name": "Vanuatu",
    "dial_code": "+678",
    "code": "VU"
  },
  {
    "name": "Venezuela, Bolivarian Republic of Venezuela",
    "dial_code": "+58",
    "code": "VE"
  },
  {
    "name": "Vietnam",
    "dial_code": "+84",
    "code": "VN"
  }
]

Using regex and VSCode Find in File function.

1. Open VSCode’s Search: Find in Files. (cmd+f)
2. Click on the regular expression button [.*]
3. Write the regular expression ^.*[STRING].*$\n, where [STRING] is your substring. It would be ^.*code.*$\n in our example scenario
4. Replace all with an empty line.

I have nvm installed on my Macbook Pro. Some deployed versions of my app run on Docker and on specific Node versions. I got different types of errors from packages and from Node when things weren't compiling. I wanted to force my Visual Studio Code editor to run certain versions of Node.

Method 1:

Set your nvm alias in your terminal to the Node version you want.

$nvm alias default 12

Method 2:

My preferred way of running the Node version is by adding it to my launch.json file.

{
  "version": "<some-version>",
  "configurations": [
  {
    "type": "node",
    "runtimeVersion": "12", // If i need to run node 12
    "request": "launch",
    "name": "Launch",
    "program": "${workspaceFolder}/sample.js"
  }

I wanted to create a Vue dropdown component that allows users to select a country. Ideally, I would prefer to use a package that provides country codes with the country selection. With over 200+ countries, I’d rather not do it by hand.

What are country codes?

Country codes are short alphabetic or numeric geographic codes, similar to state initials, except for countries.

Country code package

I found a npm package i18n-iso-countries which provides us the ISO 3166-1 code in Alpha-2, Alpha-3, and Numeric codes. We can always double-check the [official country codes] through Wikipedia.

Installation

Install with npm: npm install i18n-iso-countries --save

To use it in a browser environment, we need to register the language.

// Support English languages.
countries.registerLocale(require("i18n-iso-countries/langs/en.json"));

Creating the select input

Let’s create the country select dropdown with selected as a data variable. Selection options are generally in an Array full of Objects in label, value pairs.

<template>
  <select v-model="selected">
    <option v-for="option in options" :value="option.value">
      {{ option.label }}
    </option>
  </select>
</template>
<script>
export default {
 name: 'CountrySelection',
 data () {
   return {
     selected: null,
     options: []
   }
 }
}
</script>

Importing the country codes

Let’s import the i18n-iso-countries package and register the English locale.

<template>
  ...
</template>
<script>
const countries = require('i18n-iso-countries')
countries.registerLocale(require('i18n-iso-countries/langs/en.json'))

export default {
  name: 'CountrySelection',
  data () {
    ...
  }
}
</script>

Instead of using a data option variable, I’m going to map through the countries and create an array as computed.

<template>
 ...
</template>
<script>
const countries = require('i18n-iso-countries')
countries.registerLocale(require('i18n-iso-countries/langs/en.json'))
export default {
  name: 'CountrySelection',
  computed: {
    countries () {
      const list = countries.getNames('en', { select: 'official' })
      return Object.keys(list).map((key) => ({ value: key, label: list[key] }))
    }
  },
  data () {
    return {
      selected: null
    }
  }
}
</script>

Creating a Vue Country Code Select

Now, we can update the options to iterate through the countries computed property.

<template>
  <select v-model="selected">
    <option v-for="country in countries" :value="country.value">
      {{ country.label }}
    </option>
  </select>
</template>
<script>
const countries = require('i18n-iso-countries')
countries.registerLocale(require('i18n-iso-countries/langs/en.json'))
export default {
  name: 'CountrySelection',
  computed: {
    countries () {
      const list = countries.getNames('en', { select: 'official' })
      return Object.keys(list).map((key) => ({ value: key, label: list[key] }))
    }
  },
  data () {
    return {
      selected: null
    }
  }
}
</script>

Conclusion

Using i18n-iso-countries, we created a Vue selection component that provides us with the ISO codes of each country. This is a great addition to any Vue form for international users.

I needed to rename a bunch of .txt files to .json and I was too lazy to hand type it.
I found a quick bash script which can be ran in Mac OSX Terminal or any shell.

Renaming the files (dry run)

This script will print out the new file names but won't rename them. This is to ensure, the bash script is renaming correct .txt files.

1) cd into the directory
2) Then type in the command touch rename.sh. This will create a new shell script.
3) We need to set permissions first by making it executable. chmod 755 rename.sh.
4) Copy and paste this to rename.sh

for file in *.txt
do
  echo mv "$file" "$(basename "$file" .txt).txt"
done

5) Run ./rename.sh

Renaming .txt to .json

If your dry run is successful, then we can remove echo from script. echo is a print function of bash, similar to console.log for Javascript.

for file in *.txt
do
  mv "$file" "$(basename "$file" .txt).txt"
done

Conclusion

You can run this script for any file extension as long as you change the .txt and json.
