+# Audit Your Ruby Project For Any CVEs
+
+The [`bundler-audit` gem](https://github.com/rubysec/bundler-audit) is a handy
+tool that you can run manually or integrate into your CI workflow to warn you
+about any CVEs in your dependencies.
+
+Running this tool without any arguments will perform a check of your
+`Gemfile.lock` file. It will check against the
+[`ruby-advisory-db`](https://github.com/rubysec/ruby-advisory-db) for any CVEs
+linked to your dependencies, down to the patch-level.
+
+```bash
+$ bundle exec bundler-audit
+
+Name: puma
+Version: 4.3.12
+CVE: CVE-2024-21647
+GHSA: GHSA-c2f4-cvqm-65w2
+Criticality: Medium
+URL: https://github.com/puma/puma/security/advisories/GHSA-c2f4-cvqm-65w2
+Title: Puma HTTP Request/Response Smuggling vulnerability
+Solution: upgrade to '~> 5.6.8', '>= 6.4.2'
+
+Vulnerabilities found!
+```
+
+In this example run, a vulnerability was found in the currently installed
+version of the `puma` gem.
+
+I believe a standard `bundler-audit` command will make sure the advisory DB is
+up-to-date, but to be sure, you can run the `update` command.
+
+```bash
+$ bundle exec bundler-audit update
+
+Updating ruby-advisory-db ...
+From https://github.com/rubysec/ruby-advisory-db
+ * branch            master     -> FETCH_HEAD
+Already up to date.

+ruby-advisory-db:

+# Print DateTime Represented By Unix Timestamp
+
+A lot of tools and systems use a Unix timestamp to represent a point in time.
+It is the number of seconds since the Unix epoch (Jan 1, 1970). However, just
+looking at a timestamp like `1623867544` doesn't tell a human much. I can't
+mentally translate that to the date and time that it is representing.
+
+The `date` utility can help. Give it the `-r` flag with the timestamp value (in
+seconds) and it will display the date and time in a human-readable format.
+
+```bash
+❯ date -r '1623867544'
+Wed Jun 16 13:19:04 CDT 2021
+```
+
+See `man date` for more details.

+# Unrestrict Where ripgrep Searches
+
+One of the conveniences of [`rg`
+(ripgrep)](https://github.com/BurntSushi/ripgrep) is that by default it doesn't
+search in places you probably don't want it to search. That means it ignores
+anything specified by your `.gitignore` file, it excludes hidden files and
+directories (dotfiles, e.g. `.git/` or `.env`), and it excludes binary files.
+
+These restrictions can be incrementally undone as needed using the `-u` flag.
+
+The `-u` flag on its own will remove the ignored files restriction. This is
+equivalent to the `--no-ignore` flag.
+
+```bash
+$ rg -u pattern
+```
+
+Adding an additional `u` (`-uu`) to that flag will remove both the ignored files and
+hidden files restrictions. This is a shorthand equivalent to both `--no-ignore`
+and `--hidden`.
+
+```bash
+$ rg -uu pattern
+```
+
+Adding one more `u` (`-uuu`) will additionally remove the binary file
+restriction. Equivalent to those other two flags plus `--text`.
+
+```bash
+$ rg -uuu pattern
+```
