Once, many years ago, I stayed on the 62nd floor of the Westin Peachtree Plaza in Atlanta, Georgia.

Earlier this week, I was doing some work on AWS and wanted to know what IP addresses were being used. Luckily for me, AWS publishes this all here https://ip-ranges.amazonaws.com/ip-ranges.json. When you go through this list, you’ll quickly see that AWS has a massive asset

What if, instead of running a process-data program on this machine, we want to run it on another machine? No problem. We make a TCP connection to a process-data server on the remote machine. On the local machine, we have generate-data writing to the TCP connection, and consume-data reading from the TCP connection…

URL shortening services have been around for a number of years . Their original purpose was to prevent cumbersome URLs from getting fragmented by broken email clients that felt the need to wrap everything to an 80 column screen. Addendum: They're useful in print , too. But it's 2009 now, and this problem no longer…

ssh-keygen can sign and verify signatures, and it's way better than PGP
For years, the best way to get 10 gigabit networking on laptops was to buy an expensive, large, and hot 10 GbE Thunderbolt adapter.
