+
+I've recently come across the DJVU file format before and needed to convert it to a PDF. The most reliable way I've found to do it is via the following command.
+
+```bash
+djvups FILENAME | ps2pdf - OUTPUT_FILE
+```
+
+Where FILENAME first gets converted to the PS file format which then gets converted to a PDF with the name OUTPUT_FILE. To make things easier, I wrote a little script that does this process automatically while preserving the filename.
+
+```bash
+#!/bin/bash
+
+set -o errexit
+set -o nounset
+set -o pipefail
+
+show_usage() {
+    echo "Usage: djvu2pdf [FILENAME]"
+    exit 1
+}
+
+if [ "$#" -ne 1 ]; then
+    show_usage
+fi
+
+if ! command -v djvups > /dev/null ; then
+    echo "djvups not found. Exiting..."
+    exit 1
+fi
+
+if ! command -v ps2pdf > /dev/null ; then
+    echo "ps2pdf not found. Exiting..."
+    exit 1
+fi
+
+djvups "$1" | ps2pdf - "${1%.*}.pdf"
+```

+title: "Do-While Loop in Other Languages"

+
+Some languages like C, C++, and Java have a concept of a Do-While loop which normally look like the following:
+
+```
+do {
+    statements;
+} while(condition);
+```
+
+This would ensure that your group of statements at least run once and then continue while the condition is still met. If you're used to that pattern, then it can be annoying when you switch to another language like Python and find that it doesn't exist. To replicate this behavior, its as simple as adding an extra variable.
+
+```python
+first_run = True
+while condition or first_run:
+    first_run = False
+    statements
+```
