It's the special assignment operator.

It combines declaring a variable and assigning to it.

So instead of:

var x int
x = 12

You can do:

v := int(12)

quake120

It's hard when IP addresses are like 00:48:f4:1f:2b:c6:5f:c8:2d:f9:2b:c6:79:14:cf:db:45:a2:a4:d5:c72b:c62b:c62b:c6:c6‌:5f:c8:2d

Nathan Osman

Or if the type can be inferred, you don't even need that:

user139252

Why would anyone want to do it the long way?

Nathan Osman

v := "something"

@HeatherBrown There are cases where you want to declare a variable but assign to it later.

quake120

"Can you give me your IP address?"
12 minutes later: Okay, let me see if I can ping that

Nathan Osman

21:01

DNS FTW.

Whaaaaaat

ipv6 addresses are evil

the only way to deal with them properly is to have a DNS

which means website, which means money.

:O

user139252

I think we should switch everyone over to IPv6, but also give out a ton of free domains.

Nathan Osman

They aren't all bad.

::1 <--- localhost

Easy enough to remember.

user139252

Like each home address gets a free yourusername.personal domain.

Whaaaaaat

someone should create an IPV6 registrar

Nathan Osman

21:04

You can already set up AAA (IPv6) DNS records.

user139252

Let's submit that idea IANA. or ICANN. or whichever of them handles that.

Whaaaaaat

and give away things like <hostname>.<region>.dns.me

Nathan Osman

I've done that for my website, quickmediasolutions.com

RPi Awesomeness

Ugh. Seriously, they need to fix the 40 GPG key limit issue

It's really annoying

Whaaaaaat

everyone! pool together your money

we're gonna buy dns.me!

Nathan Osman

21:05

@RPiAwesomeness finally found it: wiki.ubuntu.com/Home?action=edit&editor=text

@Whaaaaaat For how much?

And why not dns.io ?

Sounds more tech-ish.

Whaaaaaat

dns.io is taken

dns.me is going for... $1350

Nathan Osman

Isn't dns.me ?

Ah.

user139252

I don't think that that's fair.

Whaaaaaat

hm?

Nathan Osman

@RPiAwesomeness Oh wait... that's the wrong URL.

RPi Awesomeness

21:09

@NathanOsman I found it, top-left

Nathan Osman

wiki.ubuntu.com/sethj?action=edit&editor=text

Ah, nvm.

Whaaaaaat

hmmm. dns6.io is open

Nathan Osman

Aren't those like $40 though?

Whaaaaaat

$60

RPi Awesomeness

Oops. Just saved my edit too early :P

Nathan Osman

21:10

I can get it for $43 CAD from namecheap.

Whaaaaaat

Yeah. We should totally do dns6.io

Nathan Osman

Start a fundraiser :)

Whaaaaaat

:O KICKSTARTER

@NathanOsman Make it part of QuickMediaSolutions and then make me an employee :P

Nathan Osman

I can't afford that :P

HEY.

Whaaaaaat

the only issue i can see is getting that large of a record thingy.

Nathan Osman

21:12

Oh, nvm.

Whaaaaaat

Or... dns6.io -- Brought to you by the AskUbuntu guys!

but who will use this, really?

Nathan Osman

I can get ipv6.tech for $6.

Whaaaaaat

most anyone who self-hosts is willing to buy a domain name.

Nathan Osman

Regular $52.68/yr.

Whaaaaaat

the new domain names sound kina unprofessional

Nathan Osman

21:14

If you can come up with something ending in .xyz, I can get those for just over $1.

Whaaaaaat

like we couldn't get a decent root domain for something.

Nathan Osman

dns6.us is available to US residents.

Whaaaaaat

for how much? i can get that

Nathan Osman

Probably could be gotten for under $10.

I can't purchase it myself, I'm not living or doing business in the US.

Whaaaaaat

but really, who is going to use this service?

Nathan Osman

21:16

I don't even know what the service is :P

Do you want to describe it?

Whaaaaaat

dns6.io is a free nameserver/registrar

Nathan Osman

There are lots of other places doing free subdomains.

afraid.org for one

Whaaaaaat

So instead of giving your IPv6 as FE80:0000:0000:0000:0202:B3FF:FE1E:8329, you'd give it to people as homestead.us.dns6.io

oh my god

my home wifi drives my ping up to 500+ ms

rip gaming career

Nathan Osman

But you can already do that.

RPi Awesomeness

If I'm trying to get the code from here wouldn't I do bzr branch ubuntu:anarchism DIRECTORYTOPUT?

Whaaaaaat

21:22

brb routing ethernet under the house.

afk

RPi Awesomeness

Owowow

Stupid computer has started starting up playing the most horrendous high-pitched sound every time I start it up & the only way to stop it is to mute an input in the pulse volume control thingy

Nathan Osman

@RPiAwesomeness here:

bzr pull lp:ubuntu/wily/anarchism

RPi Awesomeness

Ah

I think I need to reinstall pulse. I'm having all sorts of issues :/

Nathan Osman

But that won't work unless you've done "bzr init" in the directory.

RPi Awesomeness

Weird buzzing when people are talking, painful high-pitched whine on startup

Nathan Osman

21:28

Loose cable?

RPi Awesomeness

$ bzr pull lp:ubuntu/wily/anarchism
bzr: ERROR: Not a branch: "/home/USER/bug-fixes/anarchism-fix/.bzr/branch/": location is a repository.

@NathanOsman Huh. Interesting, I think it's my pre-amp

Nathan Osman

@RPiAwesomeness There must already be something checked out in that directory.

RPi Awesomeness

@NathanOsman I don't think so, just bzr init-repo-d it

Nathan Osman

Weird.

RPi Awesomeness

Huh. Apparently it thought it was

Directory was empty, but it thought it was a repo

SmokeDetector

21:36

[ SmokeDetector ] Offensive body detected: Installed new / not-updated 15.10 by Thomas Naser on askubuntu.com

Nathan Osman

@RPiAwesomeness What does "ls -a" show?

RPi Awesomeness

@NathanOsman Well, it had the .git directory.

I meant *.bzr

I ran your command in a totally empty directory & it worked

Whaaaaaat

meh

didn't have enough cable

wat

@SmokeDetector can someone please provide me a screenie of this? I love seeing offensive body questions

Nathan Osman

It wasn't much.

user136984

21:53

I've got a little bit of a problem at the moment...

user136984

I'm reporting a typo in a manpage following these instructions: kernel.org/doc/man-pages/reporting_bugs.html

user136984

However I have to CC this address: [email protected]

user136984

Which does not allow messages that are not TEXT/PLAIN...

Nathan Osman

I did it.

chmod for Windows is here!

user136984

Is there any way of making Gmail only be plain?

user136984

21:55

Or how do I send it also to this address?

Nathan Osman

It's fairly simple to do from Thunderbird.

user136984

I get my mail through the browser.

Nathan Osman

Then I don't know how to do it :P

user136984

And don't want to set up offline mail just for this...

user136984

:(

user136984

21:57

Is it important to have it CCed to that address?

user136984

Will it be dealt with if I just have the first one?

user136984

That is if I just send it to this address: [email protected]

user136984

It's fine, I found the plain text mode! :)

quake120

22:16

I have numerous systems that keep showing kipmi0 at 100% CPU usage

If I do ipmitool <anything>, it does not respond...Even if I try to kill kipmi0 with everything (kill, pkill, etc), it does not kill it. Any suggestions?

Rebooting the host sometimes takes care of it, but not always

terdon

@Seth did you ever post that question about getting commands to show up in bold in the zsh prompt?

user136984

@Nathan: Do you have any roadmap for your sechat script? :)

Nathan Osman

Nope.

terdon

@quake120 kill -9 doesn't work either?

user136984

@Nathan: Did you see the #17 bug report yet?

Q: How to control file access in Windows?

Go provides os.Chmod() for setting file and directory permissions. For example, if I want to ensure a file is accessible only to the current user, I can do the following: os.Chmod("somefile.txt", 0600) This works great on Linux but does absolutely nothing on Windows. After digging into the Go ...

\o/

@ParanoidPanda I can't remember...

user136984

@Nathan: By the way, what do you think I should do about the chocolate cake stuck in my computer fan?

Nathan Osman

Eat it?

user136984

It's many months old and is jamming the fan...

quake120

@terdon Nope, kill -9 does not. I thought maybe it was making a new process, but the PID is the same, so I don't think so

user136984

I'm not even too sure how to get to it...

Nathan Osman

22:25

Then I'd suggest cleaning it.

Does it have screws?

user136984

Well, there are screws underneath my laptop, so I assume that if I remove the battery and then open it up I may be able to remove the chocolate cake... But still not sure as I don't want to end up getting electrocuted... :D

Nathan Osman

Well, don't disassemble it while it's plugged in and the battery connected :P

user136984

@Nathan: Obviously not! :D But it's just that I have heard that some of the capacitors can keep some electricity in them and when I touch the motherboard I might get some...

Nathan Osman

On a laptop?

user136984

Yes.

Nathan Osman

22:29

I've never heard that one.

user136984

I understand though that I can just touch the connections with a screwdriver so that I don't get any nasty surprises (as the screwdriver should get the electricity). So perhaps it will all be ok...

user136984

I should probably have a look first though at the technical manual for model.

user136984

Anyway, goodnight guys! :)

Terrance

@ParanoidPanda Goodnight! =)

user139252

Pithos seems pretty good, yeah?

terdon

22:34

@quake120 You should probably ask a question on the main site. Make sure you also check the process' status as shown by top, for example.

Nathan Osman

Uhm... electricity doesn't quite work that way.

Electricity will flow through a conductor when there is an imbalance of charge.

user139252

@ParanoidPanda Left over energy in laptop capacitors is basically not an issue at all anymore.

Nathan Osman

Now if you want a nice shock from a capacitor, take apart an old CRT monitor. <--- DO NOT DO THIS ~~AT HOME~~ ANYWHERE

user139252

Or a disposable camera's flash :D

Journeyman Geek

Lol.

Nathan Osman

22:46

I better tack the warning onto the end of that message.

Journeyman Geek

Plugged in, cheap psu. Live heatsink....

Nathan Osman

I don't want to get sued because somebody actually did that.

Journeyman Geek

What does not kill me hurts like hell.

Nathan Osman

And don't say "people don't blindly follow advice posted here". Remember Terdon?

:P

user139252

I may or may not have at one point demonstrated to students (ages 15+) how to construct an EMP device out of a disposable camera and some copper wire.

Nathan Osman

22:48

When I was about 8, I started a fire on the kitchen table with a small "Introduction to Electricity" kit.

I was not allowed to use it unsupervised for a while after that.

user139252

When I was 10, I incorrectly shoved a wire into the header of a PSU (thinking it was the jumper pin to get it running without being connected to a full on computer. Was going for a cheap solution to an external HDD) and burned a large corner of my bedroom.

Fabby

@Seth But out of the 12 stars: 2 testimonials! (Did you like the cats?)

Nathan Osman

2?

I counted at least 4.

@HeatherBrown O_o

Fabby

@HeatherBrown Actually burned??? (Picture please? Pretty please???)

Nathan Osman

Oh please no.

This is going to give me nightmares.

Fabby

22:53

@NathanOsman When I was 15 I burnt my brother's hair trying (and succeeding) to make gun powder! >:)

user139252

@Fabby I did not have a camera at the time. Film was still the most popular format.

Fabby

@NathanOsman Really? Or jokingly?

@HeatherBrown Can I come to your classes???? (obviously reading backwards)

Nathan Osman

22:55

If you do, bring safety goggles :P

Fabby

@NathanOsman Can we actually stop making jokes about that???

(obviously reading backwards)

Nathan Osman

@Fabby That's how memes start :)

A few more random mentions and we may be onto something :)

Fabby

@NathanOsman the advantage of you is: you don't need any! (no joke; reality; your eyes are protected most of the time)

user139252

@Fabby are you under 21, living in California, and in need of a high-school diploma?

Nathan Osman

The glasses?

Fabby

22:57

@HeatherBrown No, no and no...

Nathan Osman

@HeatherBrown no, no, yes - in that order.

Fabby

@NathanOsman O_o

Nathan Osman

I graduated from high-school but I never got a diploma :P

I was homeschooled :)

user139252

22:57

Ah.

Fabby

@NathanOsman Those are deadly! Please remove from chat before someone does an @Nathan....

Nathan Osman

LOL.

That is genuinely funny.

And if they live to tell about it, I don't mind them calling it "doing a Nathan".

Fabby

@NathanOsman A capacitor is a capacitor: in a PSU or in a laptop... They're nasty if you don't know what you're doing (like @ParanoidPanda)

Nathan Osman

Hence the warning.

user139252

I will see you all after the weekend :)

Nathan Osman

22:59

I know they're nasty.

user139252

sudo shutdown -h now

Nathan Osman

@HeatherBrown Happy weekend, then.

Fabby

@NathanOsman For such a kind soul, you're kinda cruel, you know...

@HeatherBrown Ciao!!!

Nathan Osman

@Fabby (Of course, I'm kidding. I hope that didn't need to be stated.)

@NathanOsman That's how the [at]Terdon started...

Everyone knows not to do that, right????

@terdon :D

I was just thinking about you!

Why the remark that Gilles is not a biologist?

The avatar???

@terdon -----^

terdon

@Fabby No, see the transcript. As I recall, someone asked whether he was a biologist.

Oh. It was you, you ninny!

in Unix and Linux, Sep 29 at 21:27, by Fabby

@terdon Who else is a biologist? Gilles?

Fabby

:D :D :D

I can't even remember I ever wrote that!

(advanced age, I suppose)

terdon

Tsk, and still shy of that half century...

Oh, and the furthest backstory was:

in Unix and Linux, Jan 13 '14 at 21:28, by Gilles

I'm not a mushroom, I'm a part of a mushroom's reproductive apparatus

Fabby

@terdon How do you search for that stuff?
