[The link to the image in their podcast feed is broken, it appears that the cobblers children have no shoes]

Interviews about software engineering in use today.  You can learn and apply it to your own systems.  Depending on the interview some of them are higher level and some of them go quite in depth into source code and practices.

Microsoft Research

Interviews with Microsoft researchers about things they are working on for current software systems and also the things that will shape the future of computing.  Often these inverviews are very high level and over my head until doing further research and learning when something sounds interesting.

Installing Letsencrypt Certificates Manually

I needed a certificate for my private cloud server on my LAN. It is normally an automatic thing to install and update letsencrypt certificates, however with a private server that is not on the internet one must run the commands manually every 90 days.

certbot -d cloud.example.com --manual --preferred-challenges dns certonly


Please deploy a DNS TXT record under the name
_acme-challenge.cloud.example.com with the following value:

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/cloud.example.com/fullchain.pem. Your cert
   will expire on 2019-01-05. To obtain a new or tweaked version of
   this certificate in the future, simply run certbot again. To
   non-interactively renew *all* of your certificates, run "certbot
   renew"
 - If you lose your account credentials, you can recover through
   e-mails sent to paul@example.com.
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.

Split screen with tmux

I have been a long time screen user when connecting to remote machines where I don’t want to lose work if the connection drops.  I started using tmux and have been won over by it’s split screen feature.

To start tmux just run tmux and it will start and give you a nice status bar at the bottom.  You can list out your tmux sessions with the command tmux ls, and then reattach to your session with tmux attach and the session number.

By far my favorite use for tmux is split screen so I can view multiple process outputs on the same server without opening another ssh window.  tmux uses ctrl-b for it’s commands.  ctrl-b “ will split the window horizontally, and ctrl-b % will split the window vertically.  You can then use ctrl-b o to move between window panes.

The tmux manual has got to be one of the largest man pages ever, it can do much much more too.

Vi/Emacs differences are due to keyboards

I’ve been using Vim and Emacs side by side for the last week or two, one with code in it and the other with org-mode.  It made me realize that one of the main reason the interfaces are so different, vim with mode switching, emacs with so many modifier keys are because of the keyboards they came from.

If you think about Vi being used on a ADM3A terminal keyboard you’ll see the Esc key to switch modes is much more prominent than on a modern keyboard and HJKL have arrows on them for movement.

In the case of Emacs if you look at a Symbolics Lisp machine “Space Cadet” keyboard you see there are so  many modifier keys that can be utilized.

The interfaces in each editor is not necessarily the result of some ideology about how editing should be handled, but are a product of the computing environment which they were invented in.
