Linux admin made easy. Cut costs with the right tool for the job. Routine security and support is expensive, boring, and rarely done properly. How many hours a year do your staff spend checking if your systems are exposed?
First of all, let's have a look at his answers to my PowerShell contest: I got started with PowerShell relatively late; maybe Easy sysadmin 5 years ago now.
Before using PowerShell my scripting tasks were mostly done with Ruby. I really enjoyed it as a language.
At one of my previous jobs PowerShell was in heavy use there particularly by the Exchange admin so I started picking it up and then ran with it. Is there any PowerShell project of your you want to speak about?
I have a module called Idempotion that lets you easily use DSC resources directly in scripts. It's a templated wrapper around Invoke-DscResource that gives you more natural PowerShell function syntax and some additional features -WhatIf support, etc.
This is also on the GitHub page but for example, where you would use a line like this: Can you show us the way you tackled Cosine Similarity Task?
This was a pretty challenging task. I had never heard of cosine similarity before, so I had to first learn what that was, learn how to apply to it a string since it's really about numbersthen come up with an implementation that could be sufficiently golfed.
My first attempt, at characters defined functions as ScriptBlocks in variables for dot product and vector magnitude, and then called them later once the full vectors were realized.
To make a long story short, it's much better to calculate the dot product and magnitude as you go along; it just took me a while to figure out that I could do that with this algorithm.
So actually I want to talk about some of the other challenges. Unlike traditional code golfing, this is specifically a one-liner contest; so no newlines and no semicolons. This really forces you think hard about how you can do discrete tasks even variable assignment without stopping for a new statement.
The fact that we're starting with two discrete variables for the source string puts that problem right up front. After that I really want to lowercase version of the words, and then I want to group them into a hashtable.
To do lowercase, you can call. ToLower but calling methods directly is painful in code golf.
You need the entire name, need to use parentheses, if the source is not a variable or literal you also have to wrap the source in parentheses. Luckily there's a little-known parameter set to ForEach-Object.This book is a crucial library item for any System or Network Administrator regardless of how many years you have under your belt.
