Talk by Cody Mello.

The AWK utility is one of the most useful tools in the Unix toolbox, serving system administrators, programmers, and data scientists alike. Like many others, I started out using AWK as an improved replacement for cut, but it quickly became my Swiss Army knife of text manipulation in the shell. AWKs elegance lies in its ability to grow with the users needs and experience: as I learned more of the AWK programming language, I found myself abandoning my complicated grep, cut and sed pipelines, and reaching for AWK for tasks I would have done by hand in VIM, or solved with a general-purpose scripting language.

In this talk, I will give a quick introduction to AWK for the uninitiated, take a look back at how AWK has evolved 1977, and explore what AWK teaches us about designing new tools and purpose-built languages.

ABSTRACT
«Awk» sed Vi, «Ar» sed Ed
Thus begins an old, and sadly lost in the mists of Usenet, love story about Vi and Ed (who becomes her «ex»), told entirely in Unix commands. I had no idea when I started learning these arcane (guess how the «dd» command got its name) and cryptic (what about «grep»?) Unix commands how incredibly useful they would become over the next two decades. If your primary OS is Linux or OSX on the desktop, and maybe iOS or Android on the move, youll find this 40-something year joke («Unix» itself was a bad pun) has managed to embed itself into every facet of your technological life.

Being comfortable at a shell prompt and having a healthy working knowledge of Unix commands and regular expressions will give you a whole new level of capability. In this fun talk Ill introduce a few commands and shell tricks you should have in your back pocket, and show you how to start taking control of your operating system. If you ask nicely Ill even tell you about the production system I wrote using Makefiles.

Бесконечные Зависимые Выпадающие Списки в Google Sheets

В предыдущем видео «Зависимые выпадающие списки в Google Sheets» (https://youtu.be/tvzHdtW4LBU) был рассмотрен способ организации трёх-уровневого зависимого выпадающего списка с помощью стандартных формул листад.

Здесь эта тема нашла своё продолжена в виде создания зависимых выпадающих списков, размеры которых, ограничены только размером рабочего листа.
