-# Use External Diff Tool Like Difftastic
-
-Assuming we already have a tool like `difft`
-([difftastic](https://difftastic.wilfred.me.uk/introduction.html)) available on
-our machine, we can use it as a diff viewer for the various `git` commands that
-display a diff.
-
-This requires a manual override which involve two pieces — an inline
-configuration of `diff.external` specifying the binary of the external differ
-and the `--ext-diff` flag which tells these commands to use the external diff
-binary.
-
-Here is what `git show` looks like with `difft`:
-
-```bash
-$ git -c diff.external=difft show --ext-diff
-```
-
-Without the `--ext-diff` flag, it will fallback to the default differ despite
-`diff.external` being set.
-
-See `man git-diff` and friends for the `--ext-diff` flag. See `man git-config`
-for `diff.external`.

-# Create A Slice From An Array
-
-Slices in Go are a flexible abstraction over arrays. We can create a slice from
-an array with the `[n:m]` _slicing_ syntax. We specify the left and right
-(exclusive) bounds of the array that we want to create the slice relative to.
-
-We can exclude the lower bound which translates to the `0` index of the array.
-We can exclude the left bound which translates to the end of the array. We can
-even exclude both ends of the _slicing_ syntax which means creating a slice of
-the entire array.
-
-Here is an example of each of those:
-
-```go
-package main
-
-import "fmt"
-
-func main() {
-	arr := [...]string{
-		"taco",
-		"burrito",
-		"torta",
-		"enchilada",
-		"quesadilla",
-		"pozole",
-	}
-
-	firstTwo := arr[:2]
-	lastTwo := arr[len(arr)-2:]
-	all := arr[:]
-
-	fmt.Println("First two:", firstTwo)
-	// First two: [taco burrito]
-
-	fmt.Println("Last two:", lastTwo)
-	// Last two: [quesadilla pozole]
-
-	fmt.Println("All:", all)
-	// All: [taco burrito torta enchilada quesadilla pozole

-# Deterministically Seed A Random Number Generator
-
-If you need a random number in Go, you can always reach for the various
-functions in the `rand` package.
-
-```go
-package main
-
-import (
-	"fmt"
-	"math/rand"
-)
-
-func main() {
-	for range 5 {
-		roll := rand.Intn(6) + 1
-		fmt.Printf("- %d\n", roll)
-	}
-}
-```
-
-Each time I run that, I get a random set of values. Often in programming, we
-want some control over the randomness. We want to _seed_ the randomness so that
-it is deterministic. We want random, but the kind of random where we know how
-we got there.
-
-```go
-package main
-
-import (
-	"fmt"
-	"math/rand"
-)
-
-func main() {
-	seed := int64(123)
-	src := rand.NewSource(seed)
-	rng := rand.New(src)
-
-	for range 5 {
-		roll := rng.Intn(6) + 1
-		fmt.Printf("- %d\n", roll)
-	}
-}
-```
-
-In this second snippet, we create a `Source` with a specific seed value that we
-can use with a custom `Rand` struct. We can then deterministically get random
-numbers from it.

-# Write A Custom Scan Function For File IO
-
-By default a [`bufio.Scanner`](https://pkg.go.dev/bufio#Scanner) will scan
-input line-by-line. In other words, splitting on newlines such that each
-iteration will emit everything up to the next newline character.
-
-We can write our own `SplitFunc` and override the default one by calling
-`scanner.Split` with it. Our custom scan function needs to match the type
-signature of [`SplitFunc`](https://pkg.go.dev/bufio#SplitFunc).
-
-Here is a custom one that emits each individual character but omits the
-newlines.
-
-```go
-func ScanChar(data []byte, atEOF bool) (int, []byte, error) {
-	if atEOF || len(data) == 0 {
-		return 0, nil, nil
-	}
-
-	start := 0
-	for start < len(data) {
-		if !utf8.FullRune(data[start:]) {
-			return 0, nil, nil
-		}
-
-		r, size := utf8.DecodeRune(data[start:])
-		if r == utf8.RuneError {
-			return 0, nil, fmt.Errorf("invalid UTF-8 encoding")
-		}
-
-		if r != '\n' {
-			return start + size, data[start:start+size], nil
-		}
-
-		// found a \n, advance the start position
-		start += size
-	}
-
-	return start, nil, nil
-}
-```
-
-We can then use thi `ScanChar` function with a `bufio.Scanner` like so:
-
-```go
-func ReadFileByCharacter(file io.Reader) {
-	scanner := bufio.NewScanner(file)
-
-	// override default SplitFunc
-	scanner.Split(scanChar)
-
-	for scanner.Scan() {
-		char := scanner.Text()
-
-		fmt.Printf("- %s\n", char)
-	}

-# Clamp To An Endless Range
-
-The
-[`Comparable#clamp`](https://ruby-doc.org/3.3.6/Comparable.html#method-i-clamp)
-method allows us to specify the bounds of a value we want. If the target value
-is between the bounds, then we get that value. Otherwise, we gets the nearest
-end of the bounds.
-
-We can even pass a range to `#clamp` instead of separate lower and upper bound
-values. Because Ruby has beginless and endless ranges, this gives us the
-ergonomics to, say, clamp to any non-negative value with a `0..` endless range.
-
-Here is what that looks like:
-
-```ruby
-> 22.clamp(0..)
-=> 22
-> (-33).clamp(0..)
-=> 0
-> 0.clamp(0..)
-=> 0

-# Show Linting Errors In Zed
-
-When working in a language like TypeScript or Go, the language server tooling
-in [Zed](https://zed.dev/) can draw my attention to errors in my code. This
-could be an unrecognized function or variable, a type error, or a syntax error.
-When these linting errors are detected, the editor underlines them with a red
-squiggly. I can hover over offending token or statement and see what the error
-is.
-
-There are also a few mouse-free ways to do this.
-
-First, I can hit `F8` to jump to the next one of these errors in the current
-file. That will move my cursor to that location and display a small overlay
-with the error details.
-
-Second, assuming Vim mode, I can navigate my cursor over a specific highlighted
-token and then hit `Shift+k`. That will pop open the same small overlay to
-display the error details.
-
-Third, I can hit `Cmd+Shift+M` to open the _Project Diagnostics_ tab which
-displays a series of file buffer results with the offending lines and the error
-description.
