Programming is hard; Peanut Butter and Jelly Sandwich: Exact Instructions Challenge – THIS is why my kids hate me. | Josh Darnit – YouTube

[Archive.is] Exact Instructions Challenge – THIS is why my kids hate me. | Josh Darnit – YouTube

We asked the kids to write instructions for a simple task but left out that we were going to be following their instructions EXACTLY as written. Great lesson for communication and a fun practice in patience!

Via [Archive] Maarten van Smeden on Twitter: “This is why programming is an acquired skill ” / Twitter

Q

It spurred all kinds of reactions about software development, like that programming should read like poetry, software development is about slowing down your thoughts, and that some high schools and some universities do this experiment at the start of their software development curriculum.

This is a cool experiment to do, even outside the USA, as many countries or regions have their own sandwich style, some of which are way harder to make than PB&J (:

State machines in Delphi and .NET

Posted by jpluimers on 2023/02/15

Forgot to schedule this in 2014, so here it finally is, as the content is still relevant:

A long time ago (almost 10 years) I did some stuff with State Machines in .NET.

Since then the world has changed, and a lot more libraries have become available.

As I mainly use .NET and Delphi and there is a reasonable chance I need to do some more state machine work, here are some links about State Machines in both environments.

The SQL Murder Mystery

Posted by jpluimers on 2023/01/17

After last week’s posts PostgreSQL Exercises and SQLZOO: Interactive SQL tutorials (no login required), I did a Twitter search:

[Archive] pgexercises.com – Twitter Search / Twitter.

This got me to [Wayback/Archive] The SQL Murder Mystery (which is fun!).

I got there via [Archive] Lætitia on Twitter: “@nthonynowocien I’d say pgexercises is a good start for SQL pgexercises.com Even though, the last exercises are not beginner level. The SQL murder mystery is more fun mystery.knightlab.com” / Twitter

Working around Archive.is/.today/.ph/.li/.vn/.fo/.md eternal spinner “Loading” when trying to archive a page

Posted by jpluimers on 2023/01/13

I have had the below Archive.is spinner “Loading” without any progress indication on a couple of URLs the last few months and I think they are tied to having special characters in the URL-to-be-archived.

My usual workaround was to first archive in the Wayback Machine, then archive the resulting URL in Archive.is as it would automatically follow the path up to the original URL,

That of course failed when  https://web.archive.org/web/*/vx-underground.org did not want to save in Archive.is: either these would give an eternal spinner on the “Loading” page no matter the browser you were using either the escaped %2A or *:

SQLZOO: Interactive SQL tutorials (no login required)

Posted by jpluimers on 2023/01/12

[Wayback/Archive] SQLZOO has an extensive set of interactive tutorials spread over these topics:

  • basic SQL tutorials gradually getting more difficult (including some Covid-19 materials)
  • SQL “how to” style questions
  • More involved examples from easy via medium to hard
  • A White Christmas challenge

So the above is kind of a continuation of my series of games to learn software and database development PostgreSQL Exercises.

I found it via the first reaction to [Archive] Steve Polito on Twitter: “If you’re like me and want to level up your SQL game, give PostgreSQL Exercises a try. …” / Twitter (which initiated yesterday’s post):

[Archive] Loumarven Payot on Twitter: “@stevepolitodsgn I’ve also tried sqlzoo.net. Almost done with it. Next on my list are dataschool.com and selectstarsql.com” / Twitter

Which means I’ve more sites to try.

These will be the next: [Wayback/Archive] Learn SQL: Interactive SQL Book, from dataschool and [Wayback/Archive] Select Star SQL (which is an interactive book that I should be able to finish in a day full of reading and experimenting).
