@UbuntuQuestionsonU&L Because it wants to, duh

Henry White Hat Hacker

@Zacharee1 It's just a bot.

Zacharee1

I know...

Shutting down to try to fix my stupid trackpad buttons

Serg

Graphics card probably gives the sense of GUI being slower

Henry White Hat Hacker

Why does a UNIX/LINUX stackexchange bot report to this chatroom?

Serg

if i had a dime for every time i coughed, i could probably go to China already . . . .

@HenryWhiteHatHacker because those questions are related to Ubuntu

Henry White Hat Hacker

00:03

@Serg That make sense.

Serg

@RPiAwesomeness found a github account of someone copying the code

github.com/szaydel/c-primer-plus-book-6ed/tree/master/Ch17

So there's tree.h and tree.c

RPi Awesomeness

So what functions are we talking about exactly?

Oh, never mind.

Serg

For example in tree.h author defines bool DeleteItem(const Item * pi, Tree * ptree); , but then we have static void DeleteNode(Trnode **ptr);

The github version of the code differs

RPi Awesomeness

Well, I've never done actual C work, just some C++, but from what I can see, basically, you're just declaring the functions with their proper arguments.

Serg

In the book tree.c has DeleteItem implemented

RPi Awesomeness

00:08

Then, in the .c file, you're actually implementing all of the code

You're letting the compiler know what to expect

@NathanOsman, @Mateo, or @Seth would know more

But AFAIK that's what you're doing

Seth

I don't really know any more about C stuff than you do @RPiAwesomeness :P

RPi Awesomeness

Oh :P

Serg

OOOOO, Epiphany !

Seth

But that does appear to be what is happening. However how you manage to declare a function twice is beyond me.

Serg

The prototypes of the functions in .c file at the top are local to that .c file . . . they're not part of .h

Sort of like private method of a class

RPi Awesomeness

00:11

Oh, if the args are different then you're dealing with overloaded functions

Basically it's the same function name, but it can be called with different sets of arguments to produce different output

Serg

No, different names . . . .

/* protototypes for local functions */
static Trnode * MakeNode(const Item * pi);
static bool ToLeft(const Item * i1, const Item * i2);
static bool ToRight(const Item * i1, const Item * i2);
static void AddNode (Trnode * new_node, Trnode * root);
static void InOrder(const Trnode * root, void (* pfun)(Item item));
static Pair SeekItem(const Item * pi, const Tree * ptree);
static void DeleteNode(Trnode **ptr);
static void DeleteAllNodes(Trnode * ptr);

you cannot find these in tree.h

RPi Awesomeness

Oh, you're right

My bad

Seth

@RPiAwesomeness ohhh, good catch. This is one of those areas where Java is actually nice. You have to explicitly overload a function..

RPi Awesomeness

Then there's your answer.

Serg

With python it's simpler . . . .you import a file, and then add a few defs . . .

OK, I gotta run home, cuz it seems like it will rain soon

Mateo

00:15

@RPiAwesomeness huh, I don't really know anything ;P

but yeah, .h = "header"

Serg

To pho or not to pho . . .that is the question ?

Zacharee1

@Serg PHO

Well, I can't fix the touchpad

Because it's held on by plastic flat springs

Seth

@Serg Let your stack overPHO.

Zacharee1

And one is stretched out

@Seth Shut up

That was terrible

Just terrible

PAINful

Seth

It only works if you pronounce it the wrong American way :p

Serg

00:21

@Zacharee1 @Seth my bank account of 48.13 USD agrees with you , gentlemen . . . pho it is !

Zacharee1

o_O

Serg

wat ? I send out 450 $ to my friend in China, because she's broke right now . . .

Zacharee1

But now you're broke

Serg

@Zacharee1 for 2 more days . . . I've paycheck on 31st . . .

Seth

You're broke together <3

2

Zacharee1

00:22

How much?

@Seth lol

Seth

Okay, I'm getting creepy, I'll leave.

Zacharee1

Getting?

Seth

Touché.

Mateo

something about not needing to declare the static stuff @Serg ?

Serg

After tax and considering that I've missed bunch of days due to being constantly ill . . . $391.17

Mateo

00:24

(back to c++ anyway)

Zacharee1

@Serg That's $4600/yr

O_o

Serg

@Zacharee1 not quite . . . My pay is 9.5 $ per hour right now , which means every month i get around 500 $ . . . .But most of it is spend on parking fees , sadwiches and coffee

Zacharee1

You're $15000 below the poverty line

Serg

I tried eating rice for some time, but recently i just cannot bring myself to it . . . or forget my lunch at home . . . .or something . . .

@Zacharee1 well . . . technically yes . . . I am broke, degree-less , college student , with no work experience ( aside from working in 3 restaurants whose bosses probably won;t give reference anyway )

Zacharee1

true, I guess :/

Serg

00:30

Realistically speaking, I could save for a trip to china . . . but then again , I'm not the best at saving . . . I need to invest into something . . . does Canonical have stocks ?

Seth

don't believe so.

@Zacharee1 Most college students are..

Nathan Osman

@RPiAwesomeness In that statement, you're first assigning the two return values of f1() to r and e. Then you are comparing e to nil. Basically exactly what you described.

Zacharee1

@Serg ubuntuforums.org/showthread.php?t=681642

Nathan Osman

The important thing to note is that both r and e are scoped only to the if block.

Zacharee1

@Seth I have a lot to look forward to

Seth

00:31

@Zacharee1 you can get by without it, but you have to start planning in HS.

Zacharee1

without what?

Seth

without being broke and then coming out with 50k in debt.

Zacharee1

Oh, yeah

I don't even have a plan of where to go

Nathan Osman

@RPiAwesomeness I tend to suggest people stay away from the compound if unless they are doing something really simple because the way variables are overshadowed is a bit complicated and it can bite you if you're not aware of how it works.

Instead I'd do:

Zacharee1

Luckily, I think if I try, I'd be able to get at least some financial aid if it exists

Nathan Osman

00:33

r, e := f1()
if e != nil {
    ...
}

Serg

There's one guy in my major, he graduated loooong ago. What he did was basically take one - two classes per semester (so he was part time student all the time) and worked at comcast. Now that I think about it - he's smart. He basically lowered his tuition, still got his degree (even though it took him forever), and he basically avoided failing classes (because only one or two) . . .

Mateo

I just found the compound ones out, love them

Zacharee1

@Serg And he worked for a monopoly

Mateo

my variables were getting trapped in the brackets :)

Serg

Another thing that I probably should have done is to go to community college instead of 4 year university. Get associate degree, get job, then get the real degree

Oh, no . . . it's raining already outside . . . and I'm sick . . . and I've no umbrella - ella -ella . . .eh eh eh . . .

Mateo

00:37

auto something = if_this_is ? "1" : "0";

I'm really liking doing that right now ;)

Serg

Is there python certification ?

Nathan Osman

Not that I'm aware of.

Serg

Awww . . . Java has certification from oracle, there should be something for other languages too

Zacharee1

What do you mean by certification?

Serg

@Zacharee1 taking an exam , passing , and then showing-off a certificate ? I think that's an accurate definition of certification XD

Zacharee1

00:48

sigh

ah

Serg

01:04

Later guys

user139252

@Zacharee1 move to California, go to Azusa Pacific

Zacharee1

Er

user139252

You were talking about college, right?

user139252

Good school, close to the beach, affordable for a private university

Zacharee1

What's it do?

user139252

01:12

Teach you things you need to know?

user139252

What else does a college do?

Zacharee1

Does it have a focus?

user139252

Lots of them

user139252

Technology, business, education, theology, psychology, administration

Zacharee1

Wow

I kind of want to stay near home

Jon Stewart is great. Trevor Noah is great too

user139252

01:15

But I get a bonus on my student account if I refer new students!

Zacharee1

What if I apply but don't come? cough sellout cough

user139252

Then I get nothing

Zacharee1

Perfect :p

user139252

I need a date, life is boring :(

Zacharee1

Christian Mingle would be perfect >:D

user139252

01:22

Nope

Zacharee1

:)))))

Trololololol

Mateo

Zacharee1

Huh?

Mateo

thinking out loud ;P

Zacharee1

This isn't out loud

Q: Dell developer edition ubuntu 14.04 super key not working

Just picked up a precision 5510 loaded with 14.04. Everything is pretty smooth but for some reason the super key does not work ( checked with xev, it works). I downloaded the unity tweak tool and it doesn't register when I try to change the search to use the super key.

@Zacharee1 to the world! (well the part that read au chat...)

wonder if dell changed the logo on the keyboard on these new ones yet...

You dont need to read file line by line using bash. Awk does that already. For instance, you can print broken entries using this code awk '$2!="OK"{print $0}' check.log You can also just print table name and put that command into array , then act upon those array=( $(awk '$2!="OK"{p...

@muru if you have time ? I'm on mobile, need that ^answer proofread

muru

@Serg the usuall: default action on true condition is {print $0}, so the first command reduces to just: awk '$2 != "OK"'

03:04

@muru Are you an expert in vim?

muru

@HenryWhiteHatHacker Not an expert. Power user, perhaps.

@jokerdino --^ :P

Serg

@muru @HenryWhiteHatHacker i learned using vim from a YouTube video and just practice, remind me to find it later, maybe tomorrow

Henry White Hat Hacker

I got it now I can edit my python code.

I love VIM

user139252

@Serg Sorry, I was away. Did you decide?

user139252

@HenryWhiteHatHacker Real programmers use ed

Henry White Hat Hacker

@TheBrownOne What do you mean real programmers?

user139252

03:24

I use VIM for most things, including my webdesign. Though, I did get brackets and I kind of like it.

user139252

It's a joke, click the link.

Serg

Real programmers use butterflies

Henry White Hat Hacker

Real programmers use zeros and ones.

I did get my DK64 cartridge though =D

Henry White Hat Hacker

@Serg Can you give me the name of the books

Serg

@muru thanks for edit by the way, writing code from memory isn't most comfortable thing for me so far

@HenryWhiteHatHacker sure, what topics ?

user139252

@HenryWhiteHatHacker Odd Thomas, Brother Odd, Odd Hours, Odd Apocalypse, Saint Odd

muru

@Serg you said copy editing, so I left the code alone. :P

Serg

03:31

Well , it's hard to check code on mobile

I'll go have a shover ...

user139252

user139252

Shover? Do you mean shower?

You can't imagine how I would love to be able to go sleeping now...

@ByteCommander I haven't slept at all! five days working on my appartement.... Sleeping at my parents house

So tired I actually had to open the calender to see how many days I actually spent on this house

Just go get some sleep...

Serg

Yay korean spam

Byte Commander

07:28

Again!?

kos

SD is not catching those...

Byte Commander

I just flagged an almost exactly the same looking thing a few minutes ago.

Serg

@ByteCommander spammers don't take breaks

And speaking of sleep, I'm off.

I need to wake up in 4 hours and rush like an idiot for work

Even less than 4 now Since it is 1:30

SmokeDetector

[ SmokeDetector ] Manually reported question: in order to load new code onto the board by rzpcqss9483 on askubuntu.com (@ByteCommander) …

Takkat

they forgot to include their spam?

Byte Commander

07:37

@Takkat No, we just had 4 spam posts of the same type. First the Q is something blabbering about Arduinos, and then they edit it within the grace period to become full of Korean characters etc...

Takkat

let's kill it within the grace period >:)

Ferrybig

@Takkat They use the grace period to add the spam just before the 5 minute mark, leaving no edit history why the spam was there, bypassing the spam detection from smokey. By catching atleast 1 post before the edit, we will train SE spam checking with the orginal post

jokerdino

Incredible

Takkat

good that the spammer's IQ is less than ours.

jokerdino

@Ferrybig, can you guys email me the list of spammer accounts so I can destroy them?

Ferrybig

07:42

Let me check in metasmoke

Byte Commander

@jokerdino You can look at Smokey's posts in the CCHQ: chat.stackexchange.com/rooms/11540/charcoal-hq

jokerdino

It's hard work checking my emails. You want me to lurk another room too?

Ferrybig

It looks like all the 6 users that smoke detector reported are already "Page not found"

jokerdino

Yeah, I just killed them.

I am talking about future spammers.

Ferrybig

I have access to the same tools for smokedector as you have, would a list of recent reports work?

jokerdino

07:49

Would be nice but I would really like only the link to users.

Maybe hosted on a site somewhere which I can check once in a while.

Hm, I am so demanding. Woops

Ferrybig

We can ask @Undo or @404 to include a list of users on metasmoke, like already is done with the users of stackoverflow already

Byte Commander

Could Smokey keep a list of spammy user accounts of a site and report it on command?

jokerdino

@Ferrybig yeah, that looks very useful. Can I request a list for AUers?

Ferrybig

@ByteCommander There is already a list of people stored in the files of smokedetector for every blacklisted user, so that would work. I am not sure if that's really smart to send in the public. Smokedetector is running at Undo's place, and I don't have access to that, we really need to wait for him or use metasmoke

I'll just leave this here.

Good morning :)

Luís de Sousa

Hi everyone. I am trying to find out what happened to the UbuntuGIS repository/group. There are a number of things strange or broken in their PPAs.
In the past month or so there were only 2 messages send to the UbuntuGIS mail list, both authored by me.
Yesterday I was at the #debiangis IRC channel, and the folk there did not even knew the channel was shared with the UbuntuGIS team.
Is there anyone here in that team? Or anyone knows what is going on with them?

Byte Commander

@NathanOsman And I'll leave this as reply

A programming language based on that paper you linked.

Hi @kos ! Good morning ! :)

Hi @cl-netbox o/

Ferrybig

Lets start commenting on every spam post, so if they edit the post, the old revision is still stored for spam detection

Byte Commander

08:18

Really? Why that?

Do comments add the current state of a post to the revisions even if it later receives an edit within the grace period?

kos

Yes, a revision is saved as soon as you comment

Byte Commander

Ah, okay. Did not know that.

Q: What happened to the grace period?

I've edited the body of this answer (link to the answer's revision history) twice after ~21 minutes I initially posted it, the second edit ~3 minutes after the first edit, but the 5 minutes grace period for those two consecutive edits didn't apply; in fact the revision history shows two different...

^^ That's why I know. :)

terdon

09:07

@Ferrybig It is already stored, what do you mean?

Mudit Kapil

I talked to someone who's name is Ram

blade19899

@MuditKapil I talked to someone who's name is:

Ferrybig

@terdon As far as I have heard from other moderators, if a post is edited less than 5 minutes after its creation, then the new revision will override the older one. If we add at least 1 comment to the post, we prevent the overriding and proof destruction from happening (and because the post is a separate revision, the anti-spam from SE will learn to catch a edit of that content, instead of a post of that content)

blade19899

> "horsit"

terdon

@Ferrybig Yes, but I don't think that applies to posts that are deleted by spam flags. The original version is always available there AFAIK.

Mudit Kapil

09:11

he has done nothing for mke

me

I need a godfather

Ferrybig

@terdon this post got edited before the 5 minutes where over, can you see 2 revisions? There is a version without the spammy unicode, and one with those spammy unicode

Mudit Kapil

just to survive and live in this World

terdon

@Ferrybig that's what I see ^^

Mudit Kapil

fabbby i love you

terdon

If there was another revision in the middle, that's gone, yes. However, the important thing is that we see the original version that triggered the spam flags.
