Obituary, Tony Hoare

I knew him when he was in Oxford and regularly came across him in conferences and seminars. #Quicksort was revolutionary, and #CSP had a profound effect on my thinking and technical analysis. He was always self deprecating and very approachable.

Edit an embarrassing spelling SNAFU

Most aspiring #programmers and #computerscientists learn the #quicksort #algorithm

It's #inventor Tony Hoare has passed away.

🚨 Breaking News: A genius who invented things no one understands has left the building! 🤔🔍 Let's all pretend we're familiar with "quicksort" and "Hoare logic" until the next tech buzzword distracts us. 🎉

I just completed "Cafeteria" - Day 5 of #AdventOfCode in #TurboPascal, but only in #dosbox for the moment, not on the #Xi8088 because I'm at work 😅

Again, 8087 to the rescue!

I can't wait to see how long it will take on the real hardware, probably only a few seconds.

Did you know that #Pascal does not provide any procedure to sort the content of an array? Turbo Pascal did come with a very helpful example of a #QuickSort implementation as a reference, though.

🛠️🔧 Ah, the Quicksort: because nothing screams "efficient algorithm" like assembling a bookshelf without the instructions written in words 📜. Who knew the secret to avoiding bad runtime was just a Swedish-sounding random choice? IKEA: where sorting your life out is as easy as assembling a Fjällbo. 🎉

Some struggle with recursion, but as package invocation\_tree visualizes the Python call tree in real-time, it gets easy to understand what is going on and to debug any remaining issues.

See this one-click Quick Sort demo in the Invocation Tree Web Debugger:

☑️ Day 8/100: #Leetcode daily question

🟨 Question: 179. Largest Number

Today's question was good and can be answered using a custom sorting function. I did this with 3 approaches:
1. Built-in sort (provided custom key fn).
2. #quicksort
3. #MergeSort

🐈‍⬛ Check out my #GitHub where I post all the daily streak 🔥 questions and #LeetcodeContest 🏆 solutions

Vandaag was er weer mijn favorietje momentje in mijn intro-vak over algoritmen ... de QuickSort song! #kuleuven #informatica #quicksort https://youtu.be/2HjspVV0jK4?si=IbuQN8z---AxT7-e

I edited some code from a teacher and implemented #quicksort in pure structured #C, with clean coding standards!

This is on my site, and I'll share the link after the due date of the homework that this is part of.

I'm surprised neither #Copilot nor #ChatGPT4 can write #Quicksort in #REXX. Might be a good testbed for learning how to fine-tune, e.g., #CodeLlama. (Assuming CL doesn't know REXX either.) How much code for syntax to "take"?

Looking forward to sorting some red #MagicCards. #QuickSort

Randomness did me bad when showing off #QuickSort on Monday.

Lesson 15: Introduction to Algorithms by Mohammad Hajiaghayi: #quicksort and #expected #runningtime #analysis and #lowerbounds for #sorting

Worked through a #quicksort example in #ruby https://github.com/cseeman/algorithm_examples/blob/main/lib/quicksort.rb that really helped me understand how the mechanics of the recursion, and the how of the sorting.
