ಠ_ಠ ... the .NET .Read() method, at least in the PowerShell version I have, is ever so helpfully including some sort of separation between characters its reading

Lembik

it's all too windows for me :)

I am constantly amazed that people who like to code use windows at all :)

TimmyD

Reading in a text file of only 0s ... here's the resultant byte-array

110000 0 110000 0 110000 0 110000 0 110000 0 110000 0 110000 0

110000 = 48 = char'0' ... no problems there, but what's with the additional 0 between each byte?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

big/little endian?

TimmyD

Well, then my line wouldn't start 110000

Cᴏɴᴏʀ O'Bʀɪᴇɴ

wouldn't one of the endians put the zeroes after?

TimmyD

Oh, FFS ... the file encoding wasn't ANSI

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Lembik

16:23

oh no.. a downvote!

oh cruel world

TimmyD

OK, time for lunch, my brain apparently has the dumbs

Lembik

@TimmyD bon appetit

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Lembik

@CᴏɴᴏʀO'Bʀɪᴇɴ go on...

what aspect displeases you?

TimmyD

@CᴏɴᴏʀO'Bʀɪᴇɴ Staring at the output for a solid half hour wondering what was going on. Finally decided to open the file in Notepad++ and saw the encoding in the lower right.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

16:24

@Lembik Personal taste, I loathe challenges that impose (imo) needless restrictions.

Lembik

Cᴏɴᴏʀ O'Bʀɪᴇɴ

"you may not read the entire file at once"

Lembik

16:25

@CᴏɴᴏʀO'Bʀɪᴇɴ that is not needless. It is to do with efficiencty

if you want to do this on a large file you can't read it all in

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Which code golf isn't.

sure I can. file.read().

Lembik

@CᴏɴᴏʀO'Bʀɪᴇɴ well.. we do allow variations on a theme. It is a sort of restricted complexity

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I hate those problem too.

Lembik

@CᴏɴᴏʀO'Bʀɪᴇɴ sorry what I meant was that in practical situation the restriction is useful

so they are not needless

it's a programming challenge

this is a real life problem and the challenge is to write short code for it

I don't mean everyone in the world should want to do that but it's a good question for ppcg imho

Lembik

@CᴏɴᴏʀO'Bʀɪᴇɴ right.. so you have your favourite language and you want to show it can do this sort of thing

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Lembik Nope.

I don't have a favorite file IO language.

Lembik

I understand it's not the normal ppcg question.. I see my job to introduce new interesting questions

@CᴏɴᴏʀO'Bʀɪᴇɴ that's fine :) But some people do

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@TimmyD \(-_-)/ I implement the solution :P

@Lembik I encourage interesting questions, but IMO this isn't all that interesting.

Lembik

16:29

@CᴏɴᴏʀO'Bʀɪᴇɴ :( I really don't see why.

is it too practical?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

IMO

It's not very practical at all--when will you ever need to get a random line from a file ? :P

Lembik

oh I can tell you!

if you are doing machine learning and each line is a feature vector. If the file is huge you want to sample random subsets

because it's too slow to work on the whole file

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Oh, I do machine learning all the time :P

TimmyD

@CᴏɴᴏʀO'Bʀɪᴇɴ Wait, since when is PPCG about practicality? :p

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I get what you're saying though.

Lembik

16:30

@CᴏɴᴏʀO'Bʀɪᴇɴ then it's for you!

:)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@TimmyD exactly :P

@Lembik sorry, that was sarcasm

Lembik

@CᴏɴᴏʀO'Bʀɪᴇɴ well it's not that practical as I don't require the code to be fast :)

@CᴏɴᴏʀO'Bʀɪᴇɴ ah.. well some people do do machine learning :) It's not that rare

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Lembik (tangent: English is weird. "do do" is valid :P)

Lembik

I understand lots of people have made esolangs that don't support IO nicely

but that's not my fault :)

ArtOfCode

@CᴏɴᴏʀO'Bʀɪᴇɴ as is Buffalo buffalo buffalo Buffalo buffalo.

Lembik

16:32

and to many haskell is an esolang :)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@ArtOfCode I vehemently deny the validity of that statement :P

Lembik

@ArtOfCode They do indeed

ArtOfCode

@CᴏɴᴏʀO'Bʀɪᴇɴ It is! Look it up.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Haha, that's also true enough. I get that it's practical, but it doesn't make the best challenge

@ArtOfCode I've seen it before, and am mostly in denial

Lembik

@CᴏɴᴏʀO'Bʀɪᴇɴ no.. but it does make the restrictions non-needless! :)

ArtOfCode

16:33

Buffalo has three meanings: Buffalo, NY; to buffalo, as in to bully; or buffalo, the animal.

Lembik

what's the difference between a bison and a buffalo?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@ArtOfCode it should be plural :P

ArtOfCode

So Buffalo buffalo buffalo Buffalo buffalo: Buffalo (the animal) from Buffalo, NY, bully other buffalo who are also from Buffalo NY.

El'endia Starman

Buffalo is plural. Just like sheep.

Lembik

@CᴏɴᴏʀO'Bʀɪᴇɴ I think it's a good challenge because it tests the part of the ppcg community other challenges don't :)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

16:33

but the verb isn't

Lembik

and some people might extend their esolangs to support IO nicely!

ArtOfCode

@CᴏɴᴏʀO'Bʀɪᴇɴ there is no plural form of a verb.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Lembik If that's your thing, then go ahead. (edit again so I can remove downvote)

@ArtOfCode buffalo versus buffaloes

TimmyD

@El'endiaStarman Many much moosen

Lembik

done

and thanks

ArtOfCode

16:34

The infinitive is "to buffalo", then you have "I/you/we/they buffalo" or "he/she/it buffaloes"

Lembik

I have never worked so hard for a non-downvote :)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Lembik np

@ArtOfCode But buffalo is it in the first one.

ArtOfCode

buffaloes isn't a plural verb, it's a conjugation

@CᴏɴᴏʀO'Bʀɪᴇɴ no, it's they.

Lembik

@ArtOfCode well. it's the plural of a verb

Cᴏɴᴏʀ O'Bʀɪᴇɴ

buffalo is a city

ArtOfCode

16:35

the buffalo from Buffalo, they bully other buffalo.

Lembik

no one knows the answer to my question??

Cᴏɴᴏʀ O'Bʀɪᴇɴ

oh

@Lembik XD

@Lembik which one?

Lembik

what's the difference between a bison and a buffalo?

Bison are American; buffalo are their African counterparts.

3. For each code block, go through each string (things contained in quotemarks)
4. For each string, find each word (/[a-z]+/i)
