switch statements

switch statements require you to exhaustively consider all relevant or possible inputs (if you don't rely on default).

Interestingly, the notion that switch statements can require a default is reflective of the truth to the idea that when the stakes get high, we all fall back to our default level of training or function. This has global applications to our functionality and, by extension, the inputs (things,people/their methods,contexts) in our lives as well

Do the important shit first.

I guess this may be more of a project management thing, but trying to figure out what the most important part of a task is, and getting that done first.

If I'm cleaning the bathroom, I do the sink, because if I have to stop, that's typically the grossest part.

When I'm doing my taxes, I do the stupid parts that I can't afford to get wrong first.

When I'm packing for a trip, I get the stuff I need day-to-day sorted out and in my carry-on.

I don't think these are great examples, but they mean something to me.

Please teach us how to have the sink be the grossest part of the bathroom.

[–] pdavis@lemmy.world 2 points 9 months ago

Fun fact, in a pinch the sink can be used as a urinal.

It's installed on a slight angle, so water pools in the soap holders and around the back of the faucet. If we don't keep it dry, pools fill with gunge.

[–] nikosey@lemmy.world 4 points 9 months ago

so the toilet isn't #1? is it #2?

[–] acockworkorange@mander.xyz 2 points 9 months ago

You mean like Soundgarden?

[–] fubarx@lemmy.ml 8 points 9 months ago (1 children)

That things like tests, inline comments, and READMEs are helpful notes to my future self.

[–] cheese_greater@lemmy.world 3 points 9 months ago (1 children)

I want to (dont currently) live by

don't be a dick to future u

[–] acockworkorange@mander.xyz 3 points 9 months ago

I'll let future me do that.

Often when I'm working on some code, all my errors are because of something much different than what the error message is telling me. I've learned that often, most problems have a different cause and better solution.

Especially in relationship conversations.

[–] BrianTheeBiscuiteer@lemmy.world 7 points 9 months ago

I'm good at breaking down problems into small chunks and not getting overwhelmed by a big project. Do I have the motivation to finish these tasks? That's a different question.

[–] 1984@lemmy.today 7 points 9 months ago* (last edited 9 months ago) (1 children)

Breaking down problems in smaller pieces you can solve / reason about so they don't feel overwhelming. This is a very good life skill as well.

[–] cheese_greater@lemmy.world 1 points 9 months ago

I like the functional programming approach :)

[–] neidu2@feddit.nl 5 points 9 months ago* (last edited 9 months ago) (2 children)

using regex to find the absolute value of a number:
$number =~ s/-//;

using regex to check if a number is odd:
print "odd!\n" if (($number / 2) =~ /\./)

....and generally ~ab~using regex for weird stuff it wasn't intended for, because the regex engine is surprisingly efficient.

🌼 Just PERLy Things! 🌼

[–] 9point6@lemmy.world 7 points 9 months ago (1 children)

Absolute value: if less than zero multiply by -1

Is Odd: if modulo 2 is 1

At most both of those are a 3-4 (x86) CPU instructions. There's no way any regex engine is going to be remotely equivalent if we're talking about efficiency.

I always had a suspicion you perl guys were crazy

[–] flei@feddit.de 1 points 9 months ago

Absolute value: root of value^2

[–] cheese_greater@lemmy.world 2 points 9 months ago

That is beyond obscure haha! Love it

[–] xkforce@lemmy.world 4 points 9 months ago
  1. Simplify problems before trying to solve them.

  2. Generalizable solutions are better than ones that aren't.

[–] intensely_human@lemm.ee 4 points 9 months ago

One thinking skill Ive picked up from programming is to really take all the time necessary to articulate a thought using the best words.

Clear communication is worth the time and effort. Using the right word for each concept, learning new words as necessary, makes a positive impact on all the uses of that communication.

[–] cmgvd3lw@discuss.tchncs.de 3 points 9 months ago

No matter how you do, there are always other efficient ways.

[–] afraid_of_zombies@lemmy.world 3 points 9 months ago

So if you have ever dealt with PLCs beyond the basics you know that timing/parallelism is a clusterfuck of misery and pain until you get to the point where you can master it.

I am pretty decent at keeping multiple things going as a result.

[–] pdavis@lemmy.world 3 points 9 months ago

When I start a personal project I create a readme file that has a ToDo section and a Change Log section. Anything I think of that I might want to do I put under ToDo, break it into small chunks and prioritize it. When a task is completed under the ToDo section, I move it to the Change Log section. Easy to maintain, track progress, and documents both a Road Map and Changes all in one place. It also has a section for references to shared assets that need attribution. Actually to keep it simple the same document usually also has an about section, an installation section, and a usage section.

Some parts in math in high school got easier.

[–] AlmightySnoo@lemmy.world 0 points 9 months ago* (last edited 9 months ago)

Loops and recursion or just thinking iteratively in general. If you get this, then mathematical induction gets much more intuitive if you're studying math.
