For years I've used Google's public DNS service. It's famous IP address is 8.8.8.8. It's a resolves addresses faster that my internet provider.
Yesterday Cloudflare launched their DNS service which promises to be faster and better for your privacy. It has an awesome IP address: 1.1.1.1. Here are some benchmarks.
Unfortunately, by default, DNS is usually slow and insecure. Your ISP, and anyone else listening in on the Internet, can see every site you visit and every app you use — even if their content is encrypted. Creepily, some DNS providers sell data about your Internet activity or use it target you with ads. We think that’s gross. If you do too, now there’s an alternative: 1.1.1.1

More info + how to set it up on your device: https://1.1.1.1/
Recently my company Spatie launched https://dnsrecords.io, a beautiful site to quickly lookup dns records. True to form, we also opensourced it, here is the sourcecode on GitHub. If you want to do some dns lookups in your own app, you'll be happy to know that we extracted the dns lookup…
iTerm2, a populair terminal app, contained a very bad security issue. Everything you hover over was being checked if it was a clickable url. To determine if it's a valid url, the hovered over string was being checked against DNS server. So if you hover over a password, or a secret key or whatever it sent out to the internet. Obviously this is a big problem. It's fixed in the latest version. So if you use iTerm2 and haven't updated it recently, be sure to do it now! The problem is fixed in version 3.1.1.
iTerm2's leak issue was first discovered ten months ago. iTerm2's creator initially reacted by adding an option to iTerm 3.0.13 that allowed users to disable DNS lookups. The feature remained turned on by default for new and existing installations.Dutch developer Peter van Dijk, software engineer for PowerDNS, a supplier of open-source DNS software and DNS management service, re-reported this feature and this time around, he pointed out some of the severe privacy leaks not included in the first bug report.
"iTerm sent various things (including passwords) in plain text to my ISP's DNS server," van Dijk wrote flabbergasted in a bug report he filed earlier today.
This time around, George Nachman, iTerm2's maintainer, understood the severity of the issue right away and released iTerm2 3.1.1 to fix the problem within hours. He also apologized for enabling this feature by default without analyzing possible consequences in more depth.

Mohamed Said peeked behind the curtains and explains on his blog how Laravel Valet works behind the scenes.
The idea behind Valet is that it configures PHP's built-in web server to always run in the background when the operating system starts, then it proxies all requests to a given domain to point to your localhost 127.0.0.1http://themsaid.github.io/magic-behind-laravel-valet-20160506/
If you want to keep Homestead around for some projects, know that your can also use dnsmasq to point an entire domain to your Homestead installation.
