@StephenS Me neither but you said to try a new language :)

Magic Octopus Urn

"int(" = all integer conversion shortcuts... "stack" is all stack manipulation commands... etc.

Adám

@MagicOctopusUrn You're always welcome in the APL chat room.

Stephen S

@musicman523 Yup, that was the point :) now you have to find someone who actually knows it to debug it

Magic Octopus Urn

Aahaha, as an introvert, I often forget that others are a learning resource.

INTP for life.

Stephen S

Stupid Apple and their darned need for keys everywhere, you can't put a make a dev version of an Apple app with a signing key

Jim

9:02 PM

@MagicOctopusUrn INTP?

Stephen S

@Jim Myers-Briggs personality type: en.wikipedia.org/wiki/Myers%E2%80%93Briggs_Type_Indicator

Magic Octopus Urn

Also, if you like girls on Tinder it's not a bad pickup line to find nerdy girls lol.

rogaos

@musicman523 you're probably missing a main function. e.g. in the footer: main = print $ f 1 2 3

Magic Octopus Urn

"Whats your Meyers Briggs result?" "What?" Unmatch

Jim

@StephenS I didn't know there was a theory about that

Magic Octopus Urn

9:04 PM

@Jim there are multiple theories, don't stop at Meyers Briggs.

That's just the most widely accepted, with controversial results on border scenarios.

Stephen S

@Jim Myer's-Briggs just one (fairly popular) way of sorting people into buckets

Magic Octopus Urn

It's fortune 500 accepted.

Which means that fortune 500 companies paid a company to give their employees that test.

Jim

@StephenS Well, that's also how I perceive that kind of theories

@MagicOctopusUrn Seriously? That's in the US?

Magic Octopus Urn

I mean the study of psychology is generalization of the human mind.

Stephen S

@Jim This one's usually viewed more as a personality test than a theory

Magic Octopus Urn

9:06 PM

Yeah, I got mine for free from my company and they make me display it on my desk.

Stephen S

@MagicOctopusUrn That's a bit overboard 0.o for something that you can rig if you really want to

Magic Octopus Urn

Oh yeah, for sure, but buckets are buckets.

The more you can generalize your population the more efficient your infrastructure.

musicman523

@rogaos Thanks, Try it online! out of curiousity what does the $ do?

Jim

@MagicOctopusUrn I can't believe that. It seems so inappropriate

Magic Octopus Urn

I mean our company is a joke, so it may be lol.

I'll omit what our company is.

Stephen S

9:08 PM

@MagicOctopusUrn I think your company would appreciate that

Q: Degree of Unsaturation

Degree of Unsaturation This is not a particularly hard code puzzle - but I'm interested to see your multiple ways of solving it. The Degree of Unsaturation is the number of double chemical bonds between atoms, and/or the number rings in a chemical compound. You will be given the molecular for...

Stephen S

@Jim It's probably certified by a "professional" MB test giver, so it's not that much different from a diploma or something like that

DJMcMayhem

@MagicOctopusUrn What do you do at your company?

rogaos

@musicman523 Anything that comes after $ has higher precedence for anything that comes before it. So basically it's a way to avoid parentheses in function application, which can get pretty out of control. It's the same as main = print (f 1 2 3).

musicman523

@rogaos That's pretty sick. I wish Standard ML had such an operator. I wonder if I could define one...

Jim

9:10 PM

@StephenS In my company, we don't ask employees to display it/them on their desk

Can you nest them?

yup

sweet

I'm an enterprise PoC developer. They basically have me prove shit si possible.

is*

rogaos

Once you have a handle on $ and . you can make your haskell code as absurd as you like.

haskell.org/hoogle/?hoogle=%24

musicman523

9:12 PM

@rogaos . is function composition, yes?

Stephen S

@Jim Well, at least on the walls, right? or no

Jim

@MagicOctopusUrn Sometimes the projects are interesting

Magic Octopus Urn

I'm approached by business units that have idea for enterprise website solutions, then I refresh them quickly using Groovy on Grails so they can further validate the idea of converting to AngularJS 2.0

Jim

@StephenS I never witnessed that

Magic Octopus Urn

In essence I provide bullshit to prove trueshit.

rogaos

9:13 PM

@StephenS yeah. haskell.org/hoogle/?hoogle=. (the dot is part of the url)

Jim

@MagicOctopusUrn Where I work, the government gives grants for research projects like PoCs

Most of the time, companies abuse this

Doing so-called "research" projects

Magic Octopus Urn

Imagine being asked to program a website that handles customer ordering. I create a valid database definition then I make a very shitty mock-UI that is devoid of JavaScript and JSON type efficiencies...

Stephen S

@Jim #bureaucracy

Magic Octopus Urn

So it's like a static webpage with a valid database to prove a conceptual model ._.

And slowly, so slowly, I'm learning Angular and the required tech to publish my own fully-fledged web-solutions.

Our company just... Uhh... Doesn't know how to train IT resources.

Jim

@MagicOctopusUrn I'm not web developer, but I know that the learning curve of Angular is really steep

Stephen S

9:16 PM

@MagicOctopusUrn I'm interning at a startup, they just said like "here's an app we want, we'll use Cordova, go make it, go learn jQuery and this design framework, and we'll write the backend", it's working atm

musicman523

@Jim I hear it's not so much of a curve, it's more...............angular.

Jim

@musicman523 Don't know if I must star that or flee

Magic Octopus Urn

Yeah... Web Development is a different beast, if you're over 30 with a heavy bias toward a langauge it'll hurt, alot.

@StephenS at least they tell you what they want it in. With me it's "BRO YOU MADE A WEBPAGE, YOU MUST BE A GOD?" Then me trying to explain to VP level people why it's not efficient enough to support 1,000 concurrent users because I don't know Angular.

Downgoat

@MagicOctopusUrn opls angular is like opposite if efficient

Magic Octopus Urn

I'm not using angular is my point.

Downgoat

9:20 PM

though react isn't better since people render the entire page on every request

Magic Octopus Urn

I'm using full-stack bullshit to do front-end stuff because I'm a back-end developer

Downgoat

What backend syack

Magic Octopus Urn

I prototype a full-stack J2EE app, then have people come in and reprogram what I make based on the database design

full-stack Groovy on Grails at the moment, with minimal JQuery to populate 500 item+ loads.

It's awful, and should be demolished.

musicman523

Web development as a concept should be demolished.

Downgoat

Wait what why

Stephen S

9:22 PM

@musicman523 In 20 years web development will all be drag and drop, mark my words

Downgoat

how else will website be a thing

musicman523

No website, all plaintext. - Linus Torvalds

Stephen S

@Downgoat Abstract it enough, and you can just ask Watson for a website, hand him a 100 dollar bill, and you'll have one

musicman523

@StephenS I honestly hope it never comes to that

Stephen S

Four open challenges at one time in a row with no answers, that's gotta be a record

Magic Octopus Urn

9:25 PM

Hmm... Lets look at it this way. As a full-stack application, when a user accesses a website, if it's full-stack the server serves all relevant information, correct? Not true... With angular you can sense messages with a fraction of the cost because you cache the styling information with the user while using JSON combined with MsgPack to send "minified" objects to the client from the server. This cuts server stress by over 1000%.

Jim

@StephenS Indeed, I think we're gonna tend towards web application. Google tried to introduce that with ChromeOS a few years ago, but too early I think

Magic Octopus Urn

Some of my applicatios, if concurrently accessed by 1,000 people it'll crash.

If it was in angular, it'd be fine.

Downgoat

@StephenS 0/10 bluemix is pain in ass

Stephen S

@MagicOctopusUrn Well, obviously, you just gotta buy better servers

Magic Octopus Urn

FUCK BLUEMIX.

No.

Stephen, that's the point of angular.

With angular the same shitty server that'd crash with my code would run flawlessly.

Stephen S

9:26 PM

@MagicOctopusUrn I know

Magic Octopus Urn

2048kb is all you need ._.

Which made me sad to learn.

Downgoat

@MagicOctopusUrn wait what angular is front end?

at least the angular I use is front end

Magic Octopus Urn

huh?

@downgoat huh?

Downgoat

and shouldn't caching be do by web server not your backend app?

Stephen S

Back-end vs front-end: FIGHT

Magic Octopus Urn

9:27 PM

Well, yeah, I make prototypes as I said; I don't fuck with efficiency, unfortunately.

I want to learn the right way, but I've been doing my way for 8 years since grails was solid.

And they won't pay to teach me.

I just do memory leak analysis whenever my crap crashes and upgrade the stressful portions of the application to less stressfull alternatives.

I had a memory error last week that was simply from summing the number of attachments. It was eager fetching the objects and loading the full files in the memory just to count the number of attachments...

One activity with 60 attachments was crashing the whole system due to a "count attachment" query.

Just shows how stupid full-stack applications are compared to front-end mixed with API calls...

We're using AngularJS 4.0 + Protractor and JAX-RS to reimplement my PoC's atm, and it's working amazingly.

Protractor is an awesome E2E testing tool.

It's like cucumber, but it doesn't suck.

Adám

Who'll help me with a little bash question?

Jim

@Adám I can try

Adám

@Jim Thanks. Have a look at github.com/abrudz/QuadRS/blob/master/quadr

$2 is a filename

Magic Octopus Urn

@Adám whats the error?

Adám

It gets called from here: github.com/TryItOnline/tryitonline/blob/master/wrappers/quadr

.code.tio is a filename

Magic Octopus Urn

9:33 PM

Is there an error or? What's the generic question?

Adám

I I need to create an alternate file which is identical to .code.tio, but has a trailing newline, and that filename should then be instead of the $2

Magic Octopus Urn

unix.stackexchange.com/questions/31947/… ?

Is that helpful?

Not trying to trivialize it, but usually S.E. answers trigger my thoughts more than anything.

Adám

@MagicOctopusUrn Well, afaict all those add the missing newline to the offending file. I need to create a new file consisting of the original content, plus a newline.

trichoplax

I don't know bash but I'm guessing it has a duplicate file command?

musicman523

@trichoplax cp

Adám

9:38 PM

Something like this?
cat .code.tio > newcode
echo "" >> newcode

Jim

@Adám Would something like cat .code.tio > newfile && echo "" >> newfile work?

Q: Minimal command to make a copy of a file

I often find myself copy-pasting long path in order to create a copy of a file cp /path/to/file/file1 /path/to/file/file1.bkp Is there an alternative utility that will NOT require me to type the path/to/file twice? Something like - nameOfExecutible /path/to/file/file1 'bkp' Note: I don't w...

Magic Octopus Urn

I have no idea man, linux kills me at work.

musicman523

@trichoplax yeah no i'm just messing with you

Magic Octopus Urn

I host shit on a WebSphere IBM instance on a RedHat base... So..

doing anything is hell.

musicman523

@Adám cat will work fine but for anyone else reading your code cp will probably be more clear

@MagicOctopusUrn don't forget --no-preserve-root

DJMcMayhem

9:41 PM

I don't think you need the *

Adám

@MagicOctopusUrn An unknowing passerby might try that. Maybe you shouldn't post such?

Jim

@MagicOctopusUrn You can edit your messages rather than posting corrections

Adám

@musicman523 cp $2 newcode ?

musicman523

@Adám Anyone who would just blindly try that deserves the consequences

Jim

@musicman523 That's right, so that would be a cp $2 newcode && echo "" >> newcode

musicman523

9:42 PM

@Adám cp $2 newcode && echo "" >> newcode to add the newline

Magic Octopus Urn

And I misspelled illiterate, forcing me to learn the delete command.

trichoplax

@musicman523 SE is not the place for causing difficulties to people you consider deserve it

musicman523

@trichoplax I kiddddddddd is a joke

trichoplax

Ah I see

musicman523

@Adám If you need any more bash help let me know, I've been using Linux as my main OS for a year or so now so I've picked up some good tricks

Adám

9:46 PM

@musicman523 @Jim Thank you so much.
