Dan Pantry

@skiwi I am convinced Dutch is just a language that is gooble-de-gook that Dutch people speak when English people are around to make them think the language actually exists when in actual fact all the Dutch people speak English only

I can't even begin to think how you would pronounce half of those words

skiwi

@DanPantry Scheveningen, try to pronounce that

Dan Pantry

10:11

@skiwi I would, but I'm afraid I would get phlegm over my screen.

SuperBiasedMan

Besides the double vowels it looks like normal weird European language to me.

Dan Pantry

@SuperBiasedMan I like how you put "normal" and "weird" in the same sentence lol

SuperBiasedMan

Normal weird, as opposed to weird weird!

@DanPantry Yea, I put it in my profile a while back to lessen the confusion.

skiwi

Herfst is also a totally common word meaning autumn

Dan Pantry

@skiwi Who the hell thought it was a good idea to put 9 consonants next to each other?

skiwi

We only need one vowel on five consonants

Mast

10:14

@DanPantry Some languages are worse.

Dan Pantry

It's almost like vowels are a limited resource in your language

Everyone only gets a set number of vowels per year and you can't go over so use them wisely :p

SuperBiasedMan

@DanPantry Uh, maybe? I actually forget if that's used for modern irish or not. I always hear it as a vague irishish word rather than applied to the language.

Dan Pantry

So my boss wants me to put a new feature in that will enable administrators to make a report on all of the users in their branch of the company

They can select each individual user via a drop down list

There are 1134 users in one of the branches. how am I going to display 1134 users in a drop down list..

Dan Pantry

we have already done that

there are 1134 in this given branch

Dan Pantry

@Gemtastic nope

Mast

Your boss gave you a very specific feature request. I'd say: make it happen.

Dan Pantry

@Mast Lucky we don't need to support this branch (for another 2 months)

Apparently we will review it then..

Mast

And make a back-up of the original (you do use Git now, right?) in case he changes his mind.

@Mast TFS. We're all fked.

@DanPantry Are you responsible for slow performance?

Mast

Dan Pantry

10:23

@skiwi I'm one of two front end developers for this solution so.. yes

skiwi

I'd go with a combobox where you would need to type at least one or two letters before it shows any options though

Vogel612

@DanPantry just 1.2k?

you lucky bastard..

I had dropdowns populated with 10k+ Elements...

skiwi

Alternatively you could create your own "dropbox box" that's lazily loaded while scrolling

Vogel612

anyways off for lecture :D

Mast

You could use a dropdown like SE chat uses. Perhaps not exactly dropdown, but it works.

Dan Pantry

10:24

@skiwi Unfortunately every username is prefixed with the same prefix -

But this is probably the solution we'll go with.

skiwi

I'm still curious where my lecture of 3.45pm is at

Mast

Dan Pantry

@Mast That uses asynchronous loading I believe - almost like a search box.

This could work, however the underlying system call has no concept of filtering by name, so we'd have to retrieve the entire branch each time.

Mast

Your boss won't care what happens in the background, right?

Dan Pantry

He might if it brings down the other systems that rely on the same service :p

There's even a form about refactoring, that should be a 6...

Simon Forsberg

11:13

@SuperBiasedMan No you were right. As the Github webhooks were working I thought everything was working, I was confused by that. I did not think of the possibility of the scheduled tasks to stop working like that. I also did not read Duga's log-room, if I would have noticed that there were no messages there, I would have known that something was wrong.

Jeroen Vannevel

Add a value to the set? `SADD`
Remove a value from the set? `SREM`

Get the values from the set?

SMEMBERS

Because SGET would be too logical and we don't do none of that in Redis

Though I would've liked if it would be able to be called with GET -- which works for anything but a set, apparently

skiwi

Logic... Some stuff lacks it?

Dan Pantry

@JeroenVannevel this makes sense to me. SMEMBERS indicates getting membes from a set. SGET indicates getting a specific member from a set.

Mast

@skiwi I can't stand such forms.

Dan Pantry

Those are two different operations. That's like wondering why GET / !== GET /:id

skiwi

11:22

@Mast I think for students studying or just graudated they are fine, what's your problem with it?

Jeroen Vannevel

@DanPantry mm I guess. Makes sense in that light

Mast

@skiwi I never studied CS. The first time I encountered such a form I was like "More practical than theoretical, does that count somewhere?"

skiwi

This form is exactly for practical experience ;)

I wasn't clear, but it has a huge list of lots of popular languages and some paradigms

And Git knowledge

Dan Pantry

@JeroenVannevel Besides, are Sets even designed for random access? Their order is not determined.

Jeroen Vannevel

I just need to connect a given key with a small amount of string values

would you suggest another data structure?

Dan Pantry

11:25

@JeroenVannevel Sounds like a dictionary is what you need. Sets are collections of data with no defined order, the only guarantee being that each element is distinct.

Redis has support for hashes.

See redis.io/topics/data-types

My answer got 40 upvotes. I'm not sure how I feel about this.

Jeroen Vannevel

@DanPantry eh? Redis is in itself a giant dictionary

Mast

@DanPantry It means you wrote a solid answer.

Dan Pantry

@JeroenVannevel Its dictionaries all the way down.

Mast

A solid answer on a dubious question.

Jeroen Vannevel

Still don't see why I would use nested dictionaries though

Dan Pantry

11:29

@JeroenVannevel If you want random access you can't use a Set.

You could try a list if you just want to use redis as the dictionary

Since when did I know anything about data structure? wtf brain

Jeroen Vannevel

What do you mean with "I can't use random access"? I can SREM any element at any location in the set..

And it's a set, aren't those typically based on hashing?

Dan Pantry

@JeroenVannevel sets are unordered by default

Jeroen Vannevel

> Redis Sets are an unordered collection of Strings. It is possible to add, remove, and test for existence of members in O(1) (constant time regardless of the number of elements contained inside the Set).

Why does ordering matter?

Dan Pantry

because if the order isn't guaranteed, each indice will refer to an unknown string

ie, if you have a set 5 items long and you insert another element, its not guaranteed that set[5] will refer to that 6th element

Jeroen Vannevel

If you want to delete something, you have to specify to value

oh, but that's okay. I don't need any ordering

Dan Pantry

11:33

Oh, in which case, then I misunderstood your question :)

Jeroen Vannevel

I just need to have these values associated with the given key

Dan Pantry

then yeah a set should work

but you can only retrieve all of the members (or guess at random indices usign SREM).

Jeroen Vannevel

The scenario in question is associating a certain entity with a collection of agents that should be fired when that entity has any interaction happening to it

yeah, that's fine. I need to get all agents and examine their firing condition anyway

Dan Pantry

yeah set is probably the best here then

Jeroen Vannevel

Part of me is tempted to create a tree-like structure in Redis based on the idea of tables

Dan Pantry

11:35

aka hashes :)

Jeroen Vannevel

Redis |
         | Hash Users
             | Hash user1
                 | Hash username

Is that an accepted practice?

Dan Pantry

I mean that could potentially work

Although it might be better/more "Redis-y" if you were to create a string such as users:user:<id> and associate that string with the user hash instead.

(I don't know, honestly)

Jeroen Vannevel

yeah, that's pretty much what we do now: the beforementioned entity has as key '<customer>.Agent.<entityId>'

Dan Pantry

I wouldn't worry about best/worst practice, just do what solves your problem and worry about it when it becomes an issue.

Jeroen Vannevel

Nov 2 at 19:30, by Dan Lyons

Nothing is more permanent than a temporary fix that works.

Dan Pantry

11:38

Well, if it isn't an issue then who cares if its a temporary fix?

Jeroen Vannevel

Yeah, I guess I'm just not yet comfortable with the idea behind Redis

Right now we have a Redis structure of 50 elements

Dan Pantry

If you need to be able to query entire tables of users then yeah, use a hash.

Jeroen Vannevel

once it will get tested (lol, as if), it should be able to handle thousands of requests per second per customer, all in the same redis cache

Dan Pantry

But if you just need to cache user information and rapidly retrieve it when you know the id of the user, then do users:user:<id> or some similar pattern

I think if there becomes a use case where you need to store tables and tables of user information and access it like a table then you've probably gone wrong somewhere - Redis is meant to be a cache or in memory store, not a database ;-)

Welcome @kayess

JSON.parse(JSON.stringify(data))

You'd think it wouldn't be necessary. But it is.

Dan Pantry

@JeroenVannevel wtf

What kind of black magic are you doing

Jeroen Vannevel

If I don't do the stringify, it can't parse the input. Input being the result of a redis.smembers call

Dan Pantry

@JeroenVannevel it can't parse the input because the input is an object surely

Jeroen Vannevel

ya, that's what typeof says

Dan Pantry

12:02

have you considered looking at what the object contains...?

Jeroen Vannevel

and when I print it, it displays MB18Zeo2ZMEpUKHbBo_2208095915,PLubZeo2ZMEpUKdqsdqBo_2208721415

Dan Pantry

hm

Jeroen Vannevel

so I guess javascript also has the notion of a toString override?

Dan Pantry

It does

Jeroen Vannevel

Well apparently my tests work if I do the JSON magic sooooooooooooooo

assignment done

Dan Pantry

12:03

Would make sense.. JSON.stringify would ignore toString and only serialise the object's own enumerable properties

kayess

i wonder what kind of format that is, something like MIME encoded text or ?

Jeroen Vannevel

@kayess nah, randomly generated characters

Mast

@JeroenVannevel I've been amazed by that before and just wrote it down as JS magic.

Dan Pantry

@kayess it sounds to me like what @JeroenVannevel is trying to parse is an object with toString() overrided to return some kind of key or hash

Mast

If it works, don't touch it.

Unless you want to make things shinier, but don't overshine one-liners.

Jeroen Vannevel

12:05

@DanPantry the object contains all the values of a smembers call

nothing special from my side, this is node_redis' doing

Dan Pantry

@JeroenVannevel node_redis doesnt do anything special, either

node_redis just maps names (smembers) to redis calls

redis.io/topics/protocol#array-reply

Jeroen Vannevel

then I guess it's whatever kind of JSON object redis returns?

Dan Pantry

smembers should return an Array of objects

all json.parse to json.stringify will be doing is just putting that array into string form and back again

s/return/pass to a callback

hold on, I'll test with a version of redis now.

kayess

@DanPantry exactly i thought that too, that it being some kind of Gethashcode() output.

Jeroen Vannevel

just passing the data returned by redis.smembers through my function pipeline makes it blow up when it reaches a util.isArray call

Are we talking about different kinds of arrays that don't translate?

@DanPantry Sounds like the type of rookie mistake many sysadmins make.

connection.smembers(key, function (error, result) {
  console.log(result);
})

(albeit it returns strings)

Also, how cool is it that I can go on a website, click a button, get a virtual machine with redis on, test something and then click another button to dlete it all within 5 minutes.

that's awesome.

Jeroen Vannevel

eh? It returns true?

Yeah feel free to delete, I'll investigate further I guess

Dan Pantry

@JeroenVannevel yup.

put your code in love room and ping me

ill hop over after ive gone to the bathroom

Jeroen Vannevel

aha

I think I see why

on the redis.smembers() call I do a simple check on if(data) to see if it returned anything

but that will always be true since it returns an object anyway and not null or something

which is also why my logging tells me it found a key that isn't in it

Any suggestion on how to check for this that doesn't involve JSON.parse(stringify()).length?

lol. nevermind

I'll chalk it up to a brainfart

We don't have the XKCD feed here, right?

That was posted earlier

@SimonForsberg that website has a poster that is now on my desk, thank you :)

Jeroen Vannevel

We call it a I D 10 T error.

Works better when you pronounce it instead of reading.

@Phrancis I'd reject.

ALready approved before I noticed that. The edit itself is benign, but I hope it's not a sock

Mast

If you want to edit your own question, take the effort to log-in to your original account. Or don't edit.

@Phrancis drop the mods a note to request a user merge..

or write an email directly...

Phrancis

Actually, it looks like the "editing" user is the original account. Perhaps the OP had login issues when they cross-posted to CR from SO

Greetings, Programs.

Phrancis

Hey there @Donald.McLean

There's not a way to ping the mods without pinging each one individually, is there?

Zak

@Phrancis nope

Phrancis

OK

Q: What is the most generic way to provide a variable amount of outputs from a Rust function?

I am currently writing an API for machine learning algorithms in Rust and I would like for a single genetic algorithm, artificial neural network, or Bayesian network to provide multiple outputs so that for instances in which there may be redundancy, the algorithms can benefit from each other. I i...

@Vogel612 Got it covered there, I think that one actually would be on-topic on Progs. I made a comment.
