97 Things Every Programmer Should Know

This is also a book on Clean Code.

#06: Be­fore You Refac­tor

• The best ap­proach for re­struc­tur­ing starts by tak­ing stock of the ex­ist­ing code­base and the tests writ­ten against that code.
• Avoid the temp­ta­tion to rewrite every­thing.
• Many in­cre­men­tal changes are bet­ter than one mas­sive change.
• After each de­vel­op­ment it­er­a­tion, it is im­por­tant to en­sure that the ex­ist­ing tests pass.
• Per­sonal pref­er­ences and ego shouldn't get in the way.
• New tech­nol­ogy is an in­suf­fi­cient rea­son to refac­tor.
• Re­mem­ber that hu­mans make mis­takes.

#08: The Boy Scout Rule – by Robert C. Mar­tin (Uncle Bob)

criticism: doesn't that violate "never change a running software"?!!

#88: The Unix Tools Are Your Friends

• mentions BusyBox and Cygwin

Data Science at the Command Line

running the Vagrant VM not just locally on some physical machine but …

• I want to run the Vagrant VM on a strong physical machine attached to my LAN,
• I want the VM to have an interface (VirtualBox: Bridged Adapter) and its own IP address on the LAN;
• the VM's OS is ubuntu;
• its hostname is data-science-toolbox;
• I want to access the OS from another machine on my LAN, not just from the machine, that hosts the VM:

$ ssh vagrant@data-science-toolbox

If I start the Vagrant VM through its ordinary interface, Vagrant complains about a NAT rule of this names already existing.

But I am starting the VM from the Oracle VM VirtualBox Manager – that way it works without complaint.

With a entry in $HOME/.ssh/config :

# from $HOME/.ssh/config :
Host data-science-toolbox
	User vagrant

… the ssh command line is even shorter:

$ ssh data-science-toolbox

installing the tools elsewhere

Appendix A lists the command-line tools together with their home pages.
