@Phrancis damn. Is that likely to raise flags?

Phrancis

02:37

@bruglesco Yes, they will pull the call and listen to it, to get evidence

Phrancis

02:48

She had the audacity to tell the customer that she felt attacked after telling them that we couldn't help with her Google Calendar issue when the customer kept trying to get her to understand the issue was with Outlook Calendar

bruglesco

Man does she drink before she comes in?

Phrancis

I'm starting to wonder

bruglesco

@Phrancis and yes I meant fast ;]

Phrancis

Another colleague got a complaint call that he sebt to our boss to listen to the call

bruglesco

seems like the volume of complaints are escalating

(That tends to happen) The old give them the rope to hang themselves . . .

On a lighter note: Today I lost my job. . .

So more time to code!

Phrancis

03:09

Oh. Sorry to hear about that :(

bruglesco

Sorry if I sucked the life out of the room

Phrancis

No you're fine

What are your plans on the short term?

bruglesco

unemployment

I should be able to find work easy but making anything near what I was at will be hard

Phrancis

Are you going to get back into a kitchen, or focus on tech?

bruglesco

That's a hard question

Im not getting any nibbles in tech though so probably stay in the kitchen

Phrancis

03:19

You might consider help desk and IT support, good way to get your foot in the door and there are plenty of them

bruglesco

that is a good idea

I'll see if I can get any nibbles there too

I would way rather pursue tech then kitchen

Phrancis

You can probably get 15-20/hour at most entry level IT jobs

bruglesco

@Phrancis really?

Im down

Phrancis

Yeah

bruglesco

I wonder if I can fix my bug from last night or if my head will be off

Phrancis

03:23

simplyhired.com/…

bruglesco

sweet thanks

Phrancis

The one at Elsevier has 40-45k salary, that's really good for help desk

Also, don't let the Bachelors degree or whatever discourage you, I don't have a degree and have worked multiple jobs where they were looking for that in the posting

Willingness to learn/adapt and to genuinely want to help customers are worth way more than strictly technical knowledge

bruglesco

Well customer service and an accommodating nature are one strength Ive learned in the restaurant industry

Phrancis

I'd recommend making an account on ziprecruiter.com they are really great at getting recruiters to look at relevant applicants

And if you want a 2nd opinion on resume by all means let me know

bruglesco

03:41

Thanks I appreciate it. Im gonna spend tomorrow trying to polish up the old resume. I'll write a few versions tailored for different potential positions.

1 Tech
2 IT
3 Kitchen

Phrancis

Good thinking

bruglesco

I have a linkedIn Indeed and zip account

Ill just go from there I guess

Phrancis

On the IT one I would make sure to emphasize what I already mentioned, and also emphasize knowledge of Microsoft Office products, to the extent you know more than the average computer users, because a lot of jobs use Outlook and Excel quite heavily, and users call/email about Office things a lot

bruglesco

My Office knowledge is limited

Phrancis

Ah, OK. Well, good thing is that with a little Google-Fu almost every Office issue can be resolved, customers just don't often think about it because they're not used to troubleshooting tech issues :)

(and Google-Fu Master definitely belongs on an IT resume ;)

bruglesco

03:47

I am definitely a Google-fu master

It isn't just that people don't think to google it they also often don't know how to word it

Phrancis

Right, that's the key

bruglesco

and also don't have the patience to use 4+ wordings and compare the results

Phrancis

Or the knowledge of which results/sources are most likely to have the information they need

bruglesco

Most people click the top result on the first search and hope that solves it

that too

Phrancis

I actually find myself quite often finding solutions to an issue on SuperUser.SE at my work, that site is underrated

bruglesco

04:02

Aren't they notoriously unfriendly?

bruglesco

04:12

this bug is still frustrating the crap out of me

Phrancis

04:23

@bruglesco Not sure, only asked there once and had a neutral experience

@bruglesco Nothing on SO?

bruglesco

Not that kind of bug

well maybe

Phrancis

Hm. What is it about again?

bruglesco

Im writing a review of a poorly written circular linked list and trying to reimplement it.

Its the Josephus problem

Phrancis

Sounds relatively straightforward...

bruglesco

and no matter what inputs I give I get the output 1

which makes me think I am doing something stupid somewhere

Phrancis

04:28

Sounds plausible

Issues like these I tend to add a bunch of console output between instructions to follow what happens

bruglesco

yeah good idea

Phrancis

Helps with quick sanity checks

bruglesco

that was not what I expected

It changed output but didn't output any of the messages I added

Phrancis

Sounds like an incorrect conditional?

bruglesco

gotta be

Man my head isn't in it

Now I got a read access violation.

Phrancis

04:44

What is that?

Trying to access a private member from outside, possibly?

bruglesco

trying to access memory that you shouldn't

c++ memory management stuff

(obligatory point on manual memory management)

but I delete the node then seem to access it later

Phrancis

(obligatory grunt at manual memory management)

@bruglesco Wouldn't the compiler strongly object to that?

And if so, I would posit the deleting is not working

bruglesco

@Phrancis It happens at runtime and the debugger throws an exception and stops the program at the breakpoint

the deletion is working the logic surrounding moving the pointers away from referring to the deleted memory aren't working

Phrancis

Ugh pointers 😣

bruglesco

if (start_node->next == start_node)

Phrancis

04:56

Wouldn't it just be a matter of getting the next (or previous) element before deleting and reassigning the pointers?

bruglesco

That line is not working the way I intend

@Phrancis I thought I did

Phrancis

That only seems like it would work with a list of 1 element

bruglesco

that's the idea. That is returning no matter how many elements

omg I know what I did

Phrancis

Actually, what if you had 2 elements which were identical next to each other?

bruglesco

no pointers are reference to memory locations

cant have to items in the same location

Phrancis

05:00

So == is comparing by reference, rather than by value?

bruglesco

I think all of my list creation is done via copy

okay it works

That also means OP's code was probably broken

Phrancis

The copy's not equal to the original because different memory location?

bruglesco

So I probably shouldn't finish this review I just spent 3 nights on

@Phrancis right. When passing variable you can pass by value or by reference.

Phrancis

Go ahead and post it, the requirement is that the code works correctly to the OP's knowledge, plenty of answers out there pointing out weird bugs and edge cases

bruglesco

Well it TLE'd but SPOJ probably gives TLE before wrong answer

Phrancis

05:06

Yeah sites tend to do that

I've come to prefer sites that give you the challenge and ask for the answer, so you can use your own tools/IDE/whatever

Yours also getting TLE?

bruglesco

no Im getting wrong answer

Phrancis

Well, at least it's faster to get at the wrong answer ;P

Sounds like a tricky challenge, if you need to implement a circular linked list just to solve it

(doesn't C++ already have one of those?)

bruglesco

@Phrancis It wasn't the best solution (will address that in answer too)

@Phrancis nope

but they have a linked list that can return its size and a modulus operator

Phrancis

Can you do my_list[-1] to get the last element in C++?

(or whatever the syntax is -- heathen here who is used to more modern languages)

bruglesco

that's the right syntax

and no

Im pretty sure that's a segmentation fault you just did

Phrancis

05:19

So you'd have to do something like my_list[my_list.length -1] ?

bruglesco

index = index % list.size();

Phrancis

Eww

bruglesco

ohh yes

but the mod would give you wraparound

Phrancis

So long as there's a workaround I guess, as clunky as it is

Just got to reset the index any time you add or remove something

bruglesco

well for Josephus that's the point

Josephus problem

In computer science and mathematics, the Josephus problem (or Josephus permutation) is a theoretical problem related to a certain counting-out game. People are standing in a circle waiting to be executed. Counting begins at a specified point in the circle and proceeds around the circle in a specified direction. After a specified number of people are skipped, the next person is executed. The procedure is repeated with the remaining people, starting with the next person, going in the same direction and skipping the same number of people, until only one person remains, and is freed. The problem —...

Phrancis

05:27

This would be a breeze to do with Python's deque

But if you have to roll your own, yeah, PITA I guess

bruglesco

Now the online compiler is giving me an error that my own is not

C++ has a deque

Phrancis

Why don't you just use that then?

bruglesco

but it does have deletions by index

the list has the fastest deletion by index

Phrancis

* once you get it to work

Ah so you have to solve it to find how to not get executed, more challenging

Brute force becomes a problem with a larger input

bruglesco

@Phrancis gah I didn't even think of that

this answer is going to take me a week at this point

Phrancis

05:35

Well, just save it in notepad and go do something more relaxing for a while

The algorithm itself is fairly simple, but running it in reverse appears challenging

Hm actually, it's not about running it in reverse, whatever the result is of running it in the right order should be the answer

bruglesco

Yeah I need sleep. GN

Phrancis

GN

Monking!

bruglesco

@Phrancis Hey!

Phrancis

17:18

How's it going?

bruglesco

Not bad

I should probably be working on my resume but I am working on that bug instead

How bout you?

Phrancis

Just started work, still kinda sleepy

This is fun though

It turns out neural networks are bad at naming burlesque shows. http://aiweirdness.com/post/175848043097/ai-does-not-understand-sexy

Q: How to avoid logical mistakes in code, when TDD didn't help?

I was recently writing a small piece of code which would indicate in a human-friendly way how old an event is. For instance, it could indicate that the event happened “Three weeks ago” or “A month ago” or “Yesterday.” The requirements were relatively clear and this was a perfect case for test dr...

huh ^

A: How to avoid logical mistakes in code, when TDD didn't help?

These are the kinds of errors you typically find in the refactor step of red/green/refactor. Don't forget that step! Consider a refactor like the following (untested): def pluralize(num, unit): if num == 1: return unit else: return unit + "s" def convert_to_unit(delt...

This is actually a pretty good implementation ^^

Phrancis

18:29

@bruglesco Odd -- That lady coworker came in, saw her for a few minutes, and then she's been gone since -- her stuff is still at her desk though, so she must have went or been sent home I guess

skiwi

@Phrancis Is that a normal occurrence?

Phrancis

@skiwi No

On the bright side, my manager just told me that I got a kudos from the client (the hospital) and that he wish I had gotten the call first rather than she did

skiwi

Ah, that's cool

bruglesco

18:56

@Phrancis That could mean a lot of things. Suspension. Not caring about personal possessions in the wake of a termination

Or something else entirely non-disciplinary

Perhaps she has been seriously ill and it has been effecting her performance and attendance.

Finally fixed my bug

skiwi

Fixing bugs is always fun!

Well, I mean the part of having fixed the bug :P

bruglesco

yes the afterwards

skiwi

This week I've been working on a websocket implementation at work again and there were all sorts of cases of weird behaviour with messages suddenly being stopped receiving

After a bit of debugging it finally hit me that if the queue on the server was empty, then the process would stop (actually the messages would get queued forever and there's not a single way to release them), and I found a mutex/locking oversight

bruglesco

I take it you got it straightened out?

skiwi

Talked with a coworker and together we could explain all different weird issues going on, and I tested again and it was fixed :)

bruglesco

19:02

Nice

skiwi

I'm only really learning a bit of multi-threading now at my job, university didn't teach me too much of it

Another thing is accounting for all possible error situations and making sure the logic is correct in those cases

And as a colleague says: It's all about having different layers and about sending data between those layers with possibly transformations in between

Phrancis

20:48

In other news, my manager forwarded my a compliment from the VP of Information Services at the hospital about how I handled the issue last night :)

bruglesco

Sounds awesome

FreezePhoenix

21:01

Nice!

skiwi

21:22

bubble.is looks quite interesting!

Though in my opinion it already offers me more freedom at the start than I'm wanting to have, I want to make my data definitions and then be able to generate the UI for it and only tweak where needed

bruglesco

At a brief glance I'm skeptical how useful it will be

skiwi

I haven't read the documentation yet, just playing around, but data constraints already seem to be missing

i.imgur.com/8kG8f0t.gifv

It does feel pretty fluent to be honest

FreezePhoenix

21:38

@skiwi Whats dat

Oh now I see

Wait you paid for that just to play with it?

Phrancis

@skiwi It seems to be intended for non-coders, who may not even know there is such a thing as data constraints

skiwi

@FreezePhoenix No, building apps is free, would need to check out if I can actually use it too

FreezePhoenix

@skiwi technically if it is allowing you to use an editor, then...

skiwi

@Phrancis It's a bit more dumb than I hoped but maybe it'll do for my trading cards database

I think I'll pass the link to my job too as we may get interesting ideas from it

FreezePhoenix

I see no bubble.js file... they're smart.

FreezePhoenix

23:04

@bruglesco you were correct... biggest bullet doesn't always win... but it stays in the winning place for longest :P
