I've got to get a couple K pretty soon.

Mast

@Hosch250 There are so many questions on my to-do list for which I don't have the necessary experience or time. Mostly time.

Hosch250

So I'm above 10k by the time the privileges change.

I'd like to get above 20k, but I can't at this point.

Mast

@QPaysTaxes Don't worry, there is no requirement you should.

Just write good answers and the rep will come.

Don't force it the other way around.

Hosch250

Thanks, @RubberDuck

RubberDuck

@Hosch250 I meant it.

According to the WPF room, I should also be instantiating my VM's in code-behind, not the view from the VM.

I was doing that at first, but @Mat'sMug told me to change it. Going to have to discuss this.

maaartinus

@QPaysTax Have fun... I guess, I'll stay just for a few minutes now, but will surely look at it tomorrow.

Q: Batch Gradient Descent running too slowly

I wrote a simple batch gradient descent solver using python 2.7. I know this isn't the most effecient way to solve this problem, but this code should be running faster. Is there something I can change to speed it up? My gut is telling me that mse_grad2 is the problem... from __future__ impo...

Hi everyone!

Mast

Hi @maaartinus

Hosch250

Hi, @maaartinus.

You bumped me recently.

I don't care, just noticed it.

maaartinus

20:13

@Hosch250 Have I? No idea... the half life time of my memory is just a few seconds. ;)

Hosch250

In rep.

Mast

Bump != Ping

Hosch250

You got onto the first page of all users sorted by rep.

I'm not quite there.

@RubberDuck About the last comment, can you imagine any instances where the VM should be able to get itself out of the View?

RubberDuck

Get itself out of the view? ........ not off the top of my head. No.

Hosch250

The All Users page updates dynamically.

maaartinus

20:18

@Mast I see. @Hosch250 The funny thing is that the more time I spend on a CR, the fewer points I get. When I write just a note saying something like "ugly like hell", I get ten upovotes. :D

3

Hosch250

That is the DataContext.

Lol, I've noticed.

I think people have a hard time reading the long answers.

When the answers aren't on my questions, I read the first few points, skim the rest, and vote.

Mast

@Hosch250 I think people have a hard time reading.

maaartinus

And some questions seem to be simply ignored by everyone.

Hosch250

So, @RubberDuck, this is the only place that property is used: _window.DataContext = this;

Mast

@maaartinus Some questions are simply too hard to answer.

RubberDuck

20:20

@maaartinus Dude I wish I had a star for that. Ain't that the truth.

Hosch250

I think I don't need to provide a get.

Mast

@RubberDuck RSA

RubberDuck

@Hosch250 Fair enough. I didn't totally understand what was going on there, so I wanted to mention that it felt weird to have a set only property.

Mast

@QPaysTaxes Murphy.

Hosch250

Sure.

@Hosch250 I think people have a hard time reading.

RubberDuck

@QPaysTaxes worked for me when I switched to code review.

Mast

@QPaysTaxes Found the problem ^^

maaartinus

That's strange. Isn't my userId = 14363?

It works, but for a different user. ;)

Mast

14363 works

@maaartinus It targets SO.

You SO ID is different.

maaartinus

Me stupid!

Mast

20:29

581205 in your case

maaartinus

And SO stupid as well, why the hell can't I have the same id everywhere...

Mast

@maaartinus It's based on the moment you register I think. The lower your number, the quicker you joined.

@QPaysTaxes Why is it targeting SO instead of CR?

@QPaysTaxes Yes.

@QPaysTaxes Mine is 39

maaartinus

@Mast But this site shouldn't try that hard to pretend it's multiple sites. It's not. CR & SO & whatever together are a single site. A single userId would do.

Mast

@maaartinus Probably. Fixing that now is next to impossible though. So many things would break.

In your case, it would take a lot of database space for creating a user on every site possible.

Or read everything from one database, which would be very db heavy.

So I can think of a couple of reasons why it's so illogical.

maaartinus

The user doesn't need to be created, just it's ID reserved.

Mast

20:36

@maaartinus That would still be a lot. Every SO user reserved for every new beta created?

maaartinus

I hope it doesn't!

Mast

Currently it doesn't.

maaartinus

@Mast Nothing reserved, just a global ID. No place needed, just the ID would be a bit longer. Maybe two or three bits.

Yes!

Mast

Or read everything from one database, which would be very db heavy.

Your DB isn't going to like that.

Wut? What kind of needlessly complex situation are you suggesting?

maaartinus

What? Heavy DB? We're speaking about 1 registration per user and there are maybe millions of users. So maybe a few thousand writes per day.

And reads don't matter.

Mast

20:39

I thought you wanted to merge all user accounts. Have all posts/comments/answers etc. on the same ID.

Anyway, gonna eat.

maaartinus

Well, merging may be hard. But having a single ID from the beginning sounds trivial!

It was int division, needed FP.

@QPaysTaxes ORDER BY (1.0 * Score) / LEN(Body) DESC

maaartinus

My best eff is 0.33, overall best eff is 61. :(:(:(

nhgrif

20:55

Then don't divide by zero.

maaartinus

... AND LEN(Body) > 0 ...

And mine is 0.013 :D:D:D

Similar ratio (of mine to overall). Much more letters, less thinking.

Q: Print factors of number using fencepost loop

I was wondering if this code could be optimized in any way? For instance, could I use a for each loop here? Are there other ways I could write this which would make it easier for me, or the person reading it to understand? Thanks! public static void printFactors(int factorsOf) { for (int i =...

java loop

Score per Kilobyte

maaartinus

OMG, SperK. In 100 I wouldn't figure this out!

Why not simply SPerKB? Still unreadable. ScorePerKilobyte, too long. Just efficiency.

rolfl

21:08

Because the efficiency name is meaningless, and you need too many decimals to represent it. It needs to be scaled and named. Me knowing it is Score per 1024 characters makes sense, even if the column name is wrong.

The name is easy to fix, too.

There you go: data.stackexchange.com/codereview/query/329375/…

maaartinus

What I meant, I'd call it efficiency, no matter what, as it can be either too long, or meaningless, or cryptic. Given this limited choice and the access to the code, I prefer meaningless. YMMW and so can mine, tomorrow, I could claim something else.

@QPaysTaxes Right!

rolfl

My car's efficiency is 0.4558

My code-review efficiency is 1025.23659306

My code-review efficiency is 1025.23659306 (people reached per post).

maaartinus

Typical voting bpy is 0.1.

No, I meant bpy.

Bits per year. Whatelse?

rolfl

I acknowledge that SperK is a bad name, but the measure is meaningful...

Mat's Mug

@rolfl ugh.. my #2 is that lolcode fizzbuzz post... with 2012 characters

rolfl

21:15

Well, I look at the list, and it makes me realize I am verbose.

maaartinus

It's information speed. You have limited choice and the voting outcome is related... very slightly. So 0.1 bit per year, maybe.

rolfl

Pernickety.... that's what you all are.

maaartinus

@rolfl It was mainly the lowercase p, what I disliked. I read it as "Sper" + "K".

rolfl

I was too lazy to make it [S/K]

go figure

maaartinus

No, if you color a slug in one of four possible colors and send it abroad, it's 2 bits travelling abroad at the speed of slug.

rolfl

21:17

also, the whole point was to show the use of the parameters (or lack of them), and the CTE.... but, that point was long-time-missed.

Ethan Bierlein

Yo

rolfl

Also, the ifnull instead of the if-blocks.

Ethan Bierlein

How's it goin?

Y'all

Cool

Done

Whi says I was speaking about physical information? I meant something like en.wikipedia.org/wiki/…

@QPaysTaxes These gsub sounds like an illness. I always thought that the XML  were designed so that nobody uses them, but ruby seems to top them. :(

Ethan Bierlein

@QPaysTaxes NOOOOOOOOOOOOOOOOO (That's okay. It was bound to happen.)

maaartinus

Yes.

Ethan Bierlein

I cannot express the amount of excitement I have for Python 3.5

maaartinus

21:29

I know heredocs from perl/bash (no idea why I just confused them with comments), and it's a good feature in theory, but syntactically ugly. And this .gsub(/^[ \t]*> /, '') makes it impossible to remember. Why not simply a syntax like

    puts <<+MESSAGE
            > Stuff!
            > More stuff!
            > #{pound_sign}Octothorpe
          MESSAGE

doing the right thing (replace `+` by whatever char is free for this).

The indentation has been eaten by this chat.

Q: Pull data from database

I have the following script in Perl that does the following: Prompts user for time in epoch. If user enters '########', the query will look for all reports generated after that date/time. If user does not input time, it will just look for all reports in past day. Connects to a database, runs a ...

perl database

maaartinus

I see, and it's surely useful, but I'd like to have a shortcut for writing properly indented/formatted heredoc.

Thx.

Then we agree.

?

No, I'm saying that there should be some nice syntax requiring no method calls.

The possibility to call whatever is nice. Yes, a syntax sugar. A standardized and useful one.

If it's worth to use gsub-whatever-and-more-stuff, then it's worth to have the syntax sugar.

I can't recall the details of """ in py. But this doesn't matter, the point is that you nearly(?) always want to indent and this should be supported in a simple way.

Then we indeed agree.

I stand corrected. The default should behave like this.

But it may be too late for this.

Why the heck do they call "replace" "gsub"? Why not "iaexz"?

OMFG.
