Dehydrated is an easier way to sign certificates with an ACME-server. It can sign a list of domains (including wildcard domains) or a custom CSR (either standalone or completely automated), renew if a certificate is about to expire or defined set of domains changed, and revoke certificates. raad_altaie recommends it for "auto-renewing all Let's Encrypt certificates in your environment (was a huge headache before using this tool…)"
Sumatra PDF is a powerful multi-format reader for Windows. Supports PDF, EPUB, MOBI, FB2, CHM, XPS and DjVu files via a simple user interface with a top focus on speed. Thanks for this suggestion go to K0media.
Packetbeat is a lightweight, zero-latency-overhead network packet analyzer that sends data from your hosts and containers to Logstash or Elasticsearch. This passive tool lets you keep tabs on application latency and errors, response times, SLA performance as well as user access patterns and trends so you can understand how traffic is flowing through your network. Our thanks go to elk-content-share for the suggestion.
Regexp Cheatsheet is a helpful blog post on Basic Regular Expressions (BRE) and Extended Regular Expressions (ERE) syntax supported by GNU grep, sed and awk. It covers the differences between these somewhat complex tools — for example, awk doesn't support backreferences within regexp definition (i.e., the search portion). Kindly shared by its author, ASIC_SP.

TCP Throughput Calculator can help you determine your network's theoretical limit, bandwidth-delay product and TCP buffer size to help you avoid or troubleshoot network speed issues. shadeland explains, "If traffic is TCP-based, latency can have a huge effect on bandwidth."
Murder enables you to use Bittorrent to distribute files to a large amount of servers within a production environment. This approach allows for fast, scaleable deploys in large, data-center environments with hundreds or thousands of servers—where centralized distribution systems wouldn't otherwise function. Kindly recommended by mfinnigan.
