Prints integers really fast. Pads output with null bytes to length-20 for speed reasons. The code is released under CC0. The length calculation (neg_log2 * 1233 >> 12) is from Bit Twiddling Hacks, and also public domain.

Instructions on how to SSH on airplane WiFi that blocks port 22

Using SSH through airplane WiFi that blocks port 22

Many aircraft that offer wifi only permit access to machines on port 80/443, the standard http(s) ports. If you want to SSH, you have to set up an intermediate machine that hosts the SSH service on either port 80 or 443. An easy (and free) way to do this is via a Google free-tier micro instance. These instances have a 1 GB transfer ceiling per month, but so long are you are only transmitting textual data a few days per month, this limit should not be easily exceeded. Set up one of these VMs via the Google Cloud console, and select CentOS 7 as the disk image. Make sure that you allow http/https traffic on the instance, the two checkboxes in the Firewalls section of the VM settings. Optionally, set a static external IP address for your server in the VM config, in case you don't want to look up the IP each time. Then, ssh into the new VM (the IP address will be listed as the "external IP" in the list of instances) and edi
