Errrord

A constant, regular injection of aesthetic error

Some days, it's nice to be reminded that I actually make some pretty cool things https://www.instagram.com/p/BtooDodhNlU/?utm_source=ig_tumblr_share&igshid=1swijdfcwty3k

Code Golf challenge - pilot

Okay, here we go. I’ll try this out, as a few of you said you’d be up for it. I’ll use this to play with the format and to gauge your engagement.

Code Golf challenge v0: Your goal, if you choose to accept it, is to create a program which generates the first n terms of the ‘look and say’ sequence. Your program will accept an integer input, and should output n number of terms.

Test cases:

In->Out

0->1

1->11

2->21

3->1211

4->111221

5->312211

6->13112221

7->1113213211

8->31131211131221

9->13211311123113112211

10->11131221133112132113212221

The rules: You can use any language you wish. As per the challenge, the shortest solution, for each language, in number of bytes/characters, wins.

I’ll leave this one open for a bit, so don’t worry about deadlines. I’ll warn before I close submissions for this.

Good luck!

after even further tweaks, this is down by 6 characters to just 109

for(i=process.argv[2],o='1';i--;){for(c=n=s=j='';h=o[j++];){h==n?c++:(s+=c+n,n=h,c=1)}o=s+c+n}console.log(o)

I've learnt new, horrible things about javascript in the process

My original solution clocked in at 164 chars of javascript

l=(n)=>n<=0?[1]:s(l(n-1)) s=(q)=>{var v,o=[],c=0 q.forEach((n)=>n==v?c++:(v&&o.push(c,v),v=n,c=1)) return o.concat([c,v])} console.log(l(process.argv[2]).join(""))

After seeing the solution that vorbisx gave, I used a couple of learnt tricks to get my solution down further to 136 chars.

l=(n)=>n<=0?'1':s(l(n-1)) s=(q)=>{v=o=c='' for(i=0;n=q[i];i++){n==v?c++:(o+=c+v,v=n,c=1)} return o+c+v} console.log(l(process.argv[2]))

Ultimately though, extending (minimising?) their solution a bit more and forgoing the spiffy lambda functions I was able to get down to just 115 chars with this ugly one liner

for(n='1',i=0;i<process.argv[2];i++){for(c=r=s='',j=0;h=n[j];j++){h==c?r++:(s+=r+c,c=h,r=1)}n=s+r+c}console.log(n)

runs as a script on node8

Looking forward to more of these

Ready for the algorave

Create a processing sketch, export to a gif, load into Improviz, animate as a texture. That's Christmas sorted. #livecoding #improviz #algorave #processing

Five Days of Pure Data - Infinite Scrolling

Five Days of Pure Data – Infinite Scrolling

In the years that I’ve been creating things in Pure Data I have amassed quite a collection of unfinished and messy patches. Over the next few days I’ll be releasing a few of these patches and techniques that I implement when programming in Pure Data.

Infinite Scrolling

For a performance at ChipFest 10 in 2014I wanted to recreate the look of a scrolling video game but within Pure Data. Sure, I…
