Q: Why `host` and `nslookup` on Ubuntu resolve hostnames while `ping` and `telnet` do not?

I can't use git clone or even apt-get install because I get a "cannot resolve host" error. They were working before, but I have no idea what changed that broke the DNS resolve. I can't find any information about what's going on. Ping: ping google.com ping: unknown host google.com Telnet: te...

Harvest moon / super moon / full moon... can we just call it "the ludicrous moon"?

Tweeted by nathanosman_dev on September 28, 2015 at 12:37 AM

Anyone else watching for the eclipse thing?

Mateo

or just "The Moon"

got some invites too ;) careers.stackoverflow.com/cv/invitation/…

Nathan Osman

I'll probably miss it thanks to a meeting.

Zacharee1

Yeah

NASA's broadcasting it

So is sky-live.tv

Seth

Does <super>+<l> lock the unity session for anyone else?

@NathanOsman you have a meeting at 10:00 PM? o_O

Zacharee1

00:47

@Seth shouldn't it?

Could be 7 PST

Seth

@Zacharee1 don't tell me the folks that told me what time it would be at didn't mention they were telling me in EST >.>

@Zacharee1 well, I dunno. Ctrl+Alt+L is the usual one.

Zacharee1

It's supposed to start at around 10:00 - 10:20 EST

@Seth Maybe they're trying for convenience. WINKEY+L locks Windows

Mateo

this game fits right in with the theme i'm using:

;)

Seth

well I just checked the local news.. you're right @Zacharee1.

No idea why I didn't check the local news to begin with..

Zacharee1

I thought for a second you had a REALLY hi-res screen then I realized I was zoomed in @Mateo

@Seth lol

Just watch it at sky-live.tv

It's about to start

Mateo

00:51

1920x1080 not too bad, just about all I need really

Zacharee1

I have the same, but it looked extremely big because I was so zoomed in

Mateo

lol

Zacharee1

You all say this chat should stay on topic, but here we are talking about eclipses and screen resolutions

Mateo

"General" is the word I live by in here ;)

Zacharee1

NASA's broadcast is just showing annoying animations and simulations

@Mateo wise words..

Mateo

00:54

or as the description says - Normally: General

Zacharee1

sigh

ugh

Stupid markup

****Tumbleweed rolls by****

Mateo

wow, this game is strange/cool. it's called Dropsy:

Zacharee1

What is is about?

Mateo

So you play a clown, who wants to help people, It's a point/click, and the objective it to hug people

Zacharee1

lol

Great - NASA's broadcast just crashed on me

Zacharee1

01:20

****Tumbleweed rolls by again****

For an organization with access to some of the most advanced technology we have, NASA sure is bad at making reliable broadcasts

jrg

They have a lot of "scale" problems.

and live video broadcasts is not an easy thing to begin with

Zacharee1

It's not too different from live TV. It's just over the internet

jrg

Oh, no. It's way harder.

Zacharee1

How so?

jrg

So how does TV work?

Zacharee1

01:30

How is broadcasting over the internet harder than say cable or satellite?

Mateo

yeah, the video has a direct line to the stations, then sent out as primary thing on the line

Zacharee1

So it doesn't seem hard for it to be broadcast

jrg

It's typically routed over a network to a broadcast station, which sends it out via the airwaves - either via satellite or via normal TV.

cable is different, but we'll ignore that for a moment.

Mateo

so think of amazon with UPS vs. craigslist with pick it up in person

jrg

you turn your TV set on, and it listens for the signal and then displays it.

your TV doesn't do broadcasting.

satellite it sends a single "Hey, i want this channel" signal (sometimes, some sats are different)

Zacharee1

01:32

I'm not so sure you understand what I'm saying

jrg

and if you've got a bad signal, you get a bad video quality that's distorted.

now the internet is entirely different.

you have to provide it in no less than 4 codecs.

Zacharee1

Yes... but I don't care about quality

jrg

you have to do that on the fly.

and on top of that, you have to provide at least 2 different video qualities for each of those codecs.

so now we've got 8 codecs that need to be encoded on the fly.

then you need to deliver them from your datacenter or whatnot to each web browser individually.

So with TV, they just send one signal, and you're stuck. very little to go wrong there, for the most part.

but you've got the internet, and it all goes to hell in a handbasket instantly, because there's so many variables to account for.

Zacharee1

Look:

jrg

Right. That's my point.

Mateo

01:35

too many people watching ;)

jrg

There are so many moving parts that even youtube, as big as they are, gets it wrong.

(sometimes)

Zacharee1

It's not YT

jrg

or livestream. or twitch.

Mateo

@Zacharee1 which means they don't have as much experience with that

Zacharee1

It's also only one definition, and probably only one encoding method

But my point is that NASA is supposedly this hi-tech company

but they can't get their video working

jrg

01:37

So while they are quiet literally rocket scientists, they are not video codec wizards.

Don't ask me how to get a rocket into orbit, but ask me how to do video codecs and I'll do it.

They are entirely different problems to solve. :-)

Zacharee1

I'm almost certain this is a direct TV broadcast - one codec encoding, one definition and TV CC (Live)

jrg

It can't work like that.

Mateo

wow, they are using a large size too

try it in vlc :)

jrg

There is no single codec that works for Chrome, Firefox, Internet Explorer and Safari.

Mateo

Zacharee1

01:39

@Mateo ?

And this wasn't even what I was trying to say

Mateo

maybe it's your side of the network ;P

Zacharee1

Corporate network?

jrg

I'm just trying to explain that while NASA is a pretty cool, high-tech place, it's also not an easy problem.

Zacharee1

And I was just trying to make a joke

idk why I even argued

OK. Half the time the video frame doesn't even load in

Mateo

hitting almost 3 MiB's off and on

Zacharee1

01:42

3?

Yep, now the video doesn't even load in

jrg

Sorry if I came across as a little strong there @Zacharee1

Mateo

night all

Zacharee1

You people take things too literally and seriously

jrg

after the one project where I did video streaming, every time somebody complains that it's "just like TV why doesn't it work right", I have this need to explain that no, no it isn't.

Mateo

@Zacharee1 always ;P

jrg

01:46

Also, sarcasm doesn't work too well across text.

Or jokes.

or emotion in general...

Mateo

put a ;P face at the end, it might help

I see you guys were having discussion about organizations not being able to do simple things :)

I often think if people saw how the world's elite companies can't get their printers working, they would lose faith in progress. :)

They'ld either lose faith or pick up the sledgehammer. Either is appropriate.

AmagicalFishy

Hrm.

I just installed g++-4.9

For some reason, there is no "g++" command, but "g++-4.9" is a command

Is there a way to change this behavior w/o using an alias? (so things like 'make' could also work)

Nathan Osman

FOLKS, THE MOON IS RED.

AmagicalFishy

would I just rename /usr/bin/g++-4.9 to /usr/bin/g++ ?

hbdgaf

the moon is a funny color, and people are installing gcc. i rest my case.

AmagicalFishy

i've already seen the moon

:p

Nathan Osman

03:19

Ha, lol.

If the moon turns blue, I'm willing to install Vista.

Chan-Ho Suh

03:31

crap, is this what the worlds come to .. installing gcc or whatnot instead of using their own homegrown compiler

@AmagicalFishy there is usually a solid reason for naming schemes with mature projects like gcc. I'd keep it as is and live with it

Nathan Osman

I had written a compiler but the resulting binaries were 80 times slower than GCC.

Chan-Ho Suh

you're a funny kind of guy, @NathanOsman, but I like you :)

@A.B. do you read blogs ?

A.B.

He @Serg my friend. Yes, I'm reading blogs.

Serg

@A.B. can I ask . . .why ? i know , weird question, but . . . .

A.B.

@serg I read blogs, when I'm bored or if I find a link.

Serg

@A.B. I kind of feel like that's the same for a lot of people. I usually stumble upon random blogs on the internet, but i never have one regular blog that i follow :/ And here i am thinking of starting my own blog . . . . So it's kind of weird . . .

A.B.

@Serg I don't have a regular blog, too.

Serg

@hbdgaf I read around your starred post but . . .i am kinda confused why anybody would install gcc ? isn't it coming by default with ubuntu ?

@ByteCommander o/ top of the morning to you, good sir

A.B.

Morning @ByteCommander

Serg

@A.B. and @ByteCommander next question then . . .is there anything that you guys do regularly on the internet besides askubuntu ? I am trying to find ideas for my server, so i am trying to understand what would be something that people can use regularly.

A.B.

@Serg I'm using Feedly and Reddit

I just got up.

Good morning! :)

@Serg Made a minor edit to your </<</< < answer.

cl-netbox

@ByteCommander Believe it or not - I answered his question to help him - and guess what ? ... it was downvoted =) - this time I did not hesitate to delete it at once before getting too annoyed ! =) Now I try to help him this way ... :)

Serg

@ByteCommander yup, already got notified of that ^_^

Byte Commander

@cl-netbox May I tell you something?

I'm just saying this because I think you did not really understand the voting system or are too sensible about that. Please don't get me wrong, I only want to help you getting familiar here.

cl-netbox

07:49

@ByteCommander yes - with pleasure :)

Byte Commander

You should not pay that much attention to downvotes.

There are some idiots going around every now and then that downvote for fun.

Sometimes somebody has a reason for downvoting, then he'll usually explain in a comment.

cl-netbox

@ByteCommander very kind - thank you - I appreciate it :)

Byte Commander

But if you get a single downvote somewhere without any comment, this usually has no severe meaning.

Besides, it's only -2 points while an upvote gives +10...

Serg

@cl-netbox Happens sometimes. I've answered @ByteCommander 's question before and got downvoted ,too. Why? My answer wasn't answering the question or didn't exactly fit the question. Downvotes are just feedback tool : if answer sucks, a downvote is a way to tell the user about that. Like Byte said, dont worry about downvotes too much. If an answer is good, there will be people in community who see that an answer has values and upvote

Byte Commander

What I want to say is that everybody receives some now and then and it's not a reason for immediately being upset and deleting the post.

Serg

07:51

exactly ^

Byte Commander

It's a hint that your post might be improved or does not totally address the problem yet, but it should only be a motivation do the necessary edit.

Only if there are many down- and no upvotes, e.g a score of -3 or so, I would really take another close look and consider removing it.

cl-netbox

I know that it is mostly a problem with me myself - my true approach is to help others - and I thank you for helping me to getting used to it :)

I already got downvoted and did not remove my answer because other users appreciated it ...

Byte Commander

Yeah, that's what I wanted to tell you.

And never take anything here personal, unless somebody explicitly says so! ;)

The cold and objective aim of StackExchange is good for information exchange, but just sounds a bit rough to new users sometimes.

cl-netbox

@ByteCommander @Serg Thank you for talking in this nice way to me ! :)

Byte Commander

It was the same for me when I started some months ago here, but you'll get used to it.
