+# Do Something N Times
+
+With Go 1.23 there is a new for-range syntax that makes looping a bit easier
+and more compact.
+
+Instead of needing to set up our 3-part for-loop syntax, we can say we want to
+do something `N` times with `for range N`.
+
+```go
+for range n {
+	// do something
+}
+```
+
+Let's look at an actual, runnable example:
+
+```go
+package main
+
+import "fmt"
+import "math/rand"
+import "time"
+
+func main() {
+	rand.Seed(time.Now().UnixNano()) 
+
+	food := []string{"taco", "burrito", "torta", "enchilada", "tostada"}
+
+	for range 5 {
+		randomIndex := rand.Intn(len(food))
+		fmt.Println(food[randomIndex])
+	}
+}
+```
+
+The output is random and might look something like this:
+
+```bash
+$ go run loop.go
+taco
+burrito
+tostada
+taco
+enchilada
+```
+
+I appreciate this syntax addition because it feels very akin to Ruby's `#times`
+method:
+
+```ruby
+5.times do
+  # do something
+end
+```

+# Add Styled Alerts To GitHub Markdown Documents
+
+The GFM (GitHub Flavored Markdown) variant of markdown adds some nice features
+to our GitHub-rendered markdown documents.
+
+One such feature that has been around for a couple years, but which I only just
+learned about, are these styled alerts. There are five of them each with a
+different color and icon to help convey meaning.
+
+```
