i have but most sites force flash

maybe when its stable

blade19899

@Virusboy on Firefox main it's acceptable on my system. In Firefox Developer Edition, its really smooth. But, not completely stable.

Virusboy

im looking for everyday stable

Fabby

4:09 PM

I'll keep it in mind then...

Virusboy

But i think its a browser thing

blade19899

Ey wthell i can't disable html5 youtube player, in Firefox Developer Edition?

user136984

I was wondering, is there some kind of command-line Chess app which two people could download and use to play with each other, but in Terminal?

blade19899

4:13 PM

@Toroidal Yep

user136984

@blade19899 Could you link me to where I can get it from? :)

user136984

Or tell me at least what it is called?

user136984

:)

Virusboy

chessx

blade19899

@Toroidal Spoke to soon, the game can be downloaded here: BootChess by Red Sector Inc. :: pouët.net

But, online gaming or?

user136984

4:16 PM

Well, what I just want is to be able to play Chess with a friend through CLIs.

user136984

So that we can both install this program and play against each other through our CLIs.

blade19899

@Toroidal I think bootchess will help you with that, but not sure how to set that up.

user136984

@blade19899 Ok, would we have to directly connect to each other's machines, or would it be done through a central server?

user136984

Or do you not know?

user136984

:)

blade19899

4:19 PM

@Toroidal ... No, idea. You can ask that on AU

user136984

@blade19899 Ok :) When I have installed it I will probably ask on AU about that.

blade19899

never actually tried out BootChess. Saw a post on Tweakers.net just last week.

... Now, to finish my work.

user136984

@blade19899: Anyway, thank you for recommending it! :)

blade19899

I HATE IE SO F***ING BAD!

@Toroidal No problem!

blade19899

Not hundred procent sure about that.

@Virusboy Probably ben asked here before. Search Ask Ubuntu!

Fabby

@Virusboy: reboot, look in the BIOS.

(It's on the first screen of the Dell BIOS last time I used one)

Virusboy

oh wait nvm

Vader

@Oli interesting philosophy. I guess that once you have a server set up you won't be interacting with it much.

Oli

4:37 PM

@Vader You might (I am) but I do that over SSH.

Vader

That means you don't physically interact with it right?

user136984

@blade19899: BootChess is compatible with Ubuntu isn't it? Because it says that the platforms it supports as MS-DOS and Wild.

Vader

You have terminal that is synced wit the servers terminal.

Oli

@Vader Yeah, I don't have physical access to any of my online servers.

Vader

Where are they? Do you use cloud computing solutions?

like google cloud or that amazon one?

Oli

4:40 PM

Linode, but much the much

Interesting that they pride themselves in ssd hosting

I hope 8gb is enough for my xubuntu install.

Virusboy

why does sudo getSystemId return as you are not root?

user136984

@blade19899 Ok, I have downloaded the ZIP, but how do I install or run it?

Oli

@Virusboy Are there supposed to be some negatives in that question?

user136984

4:43 PM

This is the contents of the zip:

Virusboy

negatives?

no

Vader

Why would a server use SSDs don't they suck for a lot of file I/O

user136984

Oli

@Vader No. They're great.

blade19899

> ./BootChess.bin

I think?

Vader

4:44 PM

But I thought ssd only last like 72TB

user136984

@blade19899 Thanks, will try that! :)

Vader

Then you have to but a abothe rone

Oli

@Vader Well three things there: they're using them in RAID (to make swapping out faulties easy and without data loss), they're using enterprise grade disks (which have much hardier chips), and have you ever worked out it takes to organically write 72TB to a disk? You could thrash the disk and nuke their hardware if you wanted to but that's just as much a waste of your money as it is theirs.

Vader

Ofc, abusing the sdd would be no good, but SSDs are meant to be abused. You are supposed to do a lot of file I/O, otherwise why use a SSD?

user136984

If I put my brightness settings on the lowest they can be, my screen actually turns off, is it meant to do this? :D Because it seems a little odd that it actually can turn my screen off! :D

Vader

But I guess those enterprise disk are a lot better than the consumer ones

user136984

Would you happen to know @Fabby if my brightness settings are really meant to turn my screen off?

user136984

4:58 PM

:)

Vader

Are you on laptop?

Virusboy

yes

Vader

what laptop?

Are you sure the screen actually turns off?

not just fully black?

Virusboy

oh you mean @Toroidal

Vader

ooops, yes

user136984

5:04 PM

:D

Vader

get outta here @Virusboy :D

Virusboy

haha NEVA!

user136984

@Vader Yes I am on a laptop.

Virusboy

runs

user136984

Well, it either turns off, or just becomes fully black.

Vader

5:04 PM

is the backlight still on?

user136984

It looks the same as it does when my computer is off.

Vader

It would be weird if it actually turned the backlight off,

Yeah it probably off, no idea why

but as long as it doesn't do this randomly you should be fine

user136984

@Vader: Ok, I will probably ask on the main AU forums just to see if I can get any more information on this for it could be a bug.

user136984

Good idea

user136984

@Fabby: Could you just check to see if you think that it is fine. :)

Fabby

@Toroidal brightness depends on your hardware-definition. So if the brightness settings allow it, it's possible. (Mine don't)

user136984

@Fabby Is there any way to get them not to allow it?

Fabby

5:17 PM

yes.

I'm just looking at that!

Leave me alone!

:P ;-)

can you do a:

sudo find /sys/devices/ -iname *bright*

ah, lets see if he is on steam.

probably not though...

@Mateo lol

nope, i don't really hang out on steam during the work day.

hangon, i'll get on hangouts momentarily.

And wakeonlan already exists.

j0h

My 5 year old really want those castle doors to open

Nathan Osman

@jrg: I didn't see it when I asked the question.

Honest.

Mateo

oh, is that why I never could get wake on lan to work, it needs "magic" to work?

Nathan Osman

6:52 PM

Well... here's my problem:

1

Q: How to wake my PC with any packet, not just a magic packet?

Currently, I can wake my PC by sending a magic packet from another device on the LAN. However, the PC will not power on when I send the packet from outside the network (WAN), even though I have my router instructed to forward UDP traffic on port 9 to the PC. If I run wireshark on the machine and...

networking wakeonlan

It works from within the network.

But it doesn't work over WAN.

Fabby

@NathanOsman: Broadcast!

Nathan Osman

@Fabby I'm not sending it as a broadcast packet over WAN.

Fabby

You need to forward it to the broadcast address...

That's my point...

I did this years abo...

lemme look

lmgtfy.com/?q=wake+on+lan+broadcast+internet

Mateo

:(

Fabby

@Mateo: why the sad face?

Nathan Osman

6:57 PM

And... my router won't let me forward to the broadcast address :(

Neither 255.255.255.255 nor the link-local broadcast address (192.168.1.255) work.

:(

Fabby

mmh...

does it allow you to put 1.2.3.4 in there?

Nathan Osman

Nope: "Server IP address must be a LAN IP address. "

Mateo

does yours have dmz?

Fabby

put some weird address in, telnet into the router and manually change it!

(it's bound to run linux...)

Nathan Osman

I don't have telnet access to this router :(

That's something I miss from my old DD-WRT router :(

Fabby

7:00 PM

you're not home...

What do you have?

Nathan Osman

No, I'm home.

Fabby

have you tried?

NAAA...

Nathan Osman

@Fabby Netgear Nighthawk X6 R8000.

RPi Awesomeness

Ugh. Money :P

Fabby

good stuff, but alas no telnet...

Mateo

7:02 PM

@NathanOsman try putting the computer on dmz then sending to the broadcast

Fabby

that's the problem with consumer routers...

@Mateo: good idea!

RPi Awesomeness

Do I get the new Raspberry Pi 2, a new mouse (my current one is dying), or the Patriots Super Bowl shirt. sigh

Nathan Osman

I do have one last idea if nothing else works...

Fabby

go ahead

Nathan Osman

I have a Raspberry Pi connected wirelessly that is always powered on and connected to the network.

Mateo

7:03 PM

@RPiAwesomeness that is an easy one.

Nathan Osman

I could SSH into that and send the packet from there.

Fabby

@RPiAwesomeness: learn to use the keyboard, walk around naked and get the Pi!

@NathanOsman: no! It's an elegant hack!

RPi Awesomeness

@Fabby ;)

Nathan Osman

But that would be a pain.

RPi Awesomeness

@Mateo It is?

Mateo

7:04 PM

Pi

RPi Awesomeness

Actually...I think I'm going to be forced to wait for the Pi :P

Fabby

you can set up a daemon and if you send a WOL packet to the Pi

Mateo

because they say the new one will run ubuntu right, and win 10

RPi Awesomeness

Element14 is OOS :(

user136984

Oh dear... I have got a problem!

Fabby

7:04 PM

it forwards it to all IP packets on the LAN

RPi Awesomeness

So. Mouse or t-shirt. Still decisions :P

Nathan Osman

@Fabby That would be a lot of work.

Fabby

@Toroidal: What?

RPi Awesomeness

Or both. I can probably get both...

Fabby

@NathanOsman: so take the small pain...

user136984

7:05 PM

I executed startx in one of my terminals (CTRL+ALT+F1) and now it is asking me for an admin password there but not mouse and it not clicked in the box there on the GUI so can't do anything about it!

Fabby

OK, I'm back to Toroidal's problem: at least @NathanOsman has a workaround!

RPi Awesomeness

Oh dear

Mateo

user136984

What should I do?

user136984

Oh

user136984

Ok

Fabby

I just told you

RPi Awesomeness

7:07 PM

Don't reboot

Fabby

Don't cause any additional problems

user136984

We posted the messages at the same time. :D

RPi Awesomeness

Right click

@Toroidal It's Xkill that' causing the mouse I think

Fabby

I'm still busy with your black screen

user136984

Wait...

Fabby

7:07 PM

@Toroidal: listen to @RPiAwesomeness...

user136984

I managed to get back to console status there of how startx was doing...

user136984

And have done CTRL+C.

user136984

And I have quite out of x server now.

user136984

Phew...

user136984

:)

user136984

7:08 PM

So all if well now and I am out of that terminal.

RPi Awesomeness

Ouch. $10 shipping. Guess I'm not getting the Pi :P

Fabby

@Toroidal: I've shown you the kernel parameters of your shitty screen, right?

user136984

Well, won't be executing startx again! :D

user136984

@Fabby Have you?

Fabby

Well, I can't seem to figure out a way of setting the minimum screen brightness without major work

(custom kernel)

(or custom daemon)

user136984

7:10 PM

I tried something that KasiyA said to do and it completely destroyed my brightness settings! :D

Fabby

I didn't!

What did he tell you to do?

user136984

Well he has deleted his answer now, but he told me to do: gksudo gedit /etc/default/grub

Fabby

no!

Don't change the kernel params!

user136984

And then he said to append some text to the end of a line.

Fabby

that won't work!

user136984

7:12 PM

I know...

Fabby

yeah yeah!

Forget that.

user136984

It caused real havoc! :D

Fabby

Off course!

OK, so the only thing I can provide is a workaround...

user136984

He edited my question to include info on that, and then I added some more: askubuntu.com/posts/580903/revisions

Fabby

reading

yeah!

so:

custom shortcut key that brings brightness to half.

the other ways are:

custom kernel

custom module

custom daemon

user136984

7:14 PM

Hmm...

Fabby

And you know what the command to start a store-and-forward mail server is, right?

user136984

Is there no way then to set a minimum brightness?

Fabby

in short: no

user136984

I think you told me, several times about the store-and-forward mail server thing... :D

Fabby

you can go lower then 0

but you cannot block it at 1

you can go above the maximum brightness (though not recommended)

but that's it!

Not enough idiots like you have requested this feature! :D

user136984

7:16 PM

But if it is blocking me from going beyond 0, then surely it is set somewhere?

Fabby

You can go below 0

user136984

Oh, well, I don't think it let me do that.

Fabby

you cannot block above 0

user136984

Well, I tried and it did not allow me to get into the minus numbers...

Fabby

(not without: custom kernel custom module custom daemon)

user136984

7:18 PM

Anyway, I think that I will probably have to suggest the feature...

user136984

Which package do I suggest it to?

Fabby

Yeah! :)

user136984

:)

Fabby

Call Linus!

:P

Meaning: (I'm not willing to spend the time doing that...)

user136984

:D

user136984

7:19 PM

So which package do I suggest it to?

user136984

As I am doing this through LaunchPad.

Fabby

So, my apologies: possible, but extremely difficult!

You wish!

This is the kernel!

user136984

So how do I suggest it?

Fabby

You have to do it yourself, and then submit the code...

user136984

Oh...

user136984

7:20 PM

Ok

Fabby

there are no "suggestions" for the kernel

:P

user136984

So I would have to find out how to do it myself first?

Fabby

Linus doesn't program any more...

He just accepts code from others (or not!)

user136984

:D

Fabby

Yes, indeed!

user136984

7:21 PM

Fabby

(and write beautiful, humorous code)

Good luck!

I'm back to dessert!

user136984

@Fabby you asked me about the italics I removed from askubuntu.com/q/580599/117103: Most style guides regard italics as emphasis - and (in my opinion) there really was no need to emphasize the obvious :-)

user136984

@Fabby: Good luck with the desert! :D

Fabby

@guntbert:Thank you for the feed-back...

So I'll try to remember to refrain from doing that again.

(I've been doing it for so long to emphasize the question even when on the last line that it'll take a while not to do it ever again!)

Mateo

7:27 PM

@RPiAwesomeness you could try to apply to be a road tester: element14.com/community/roadTests/1400?ICID=hp-Pi2roadtest-ban and do a live review?

guntbert

@Fabby I don't think it is very important, I certainly would not have edited the question just to remove them, my main point was the not really relevant 14.04.

Fabby

@Toroidal: did you hear that?

user136984

@Fabby Hear what?

KasiyA

Hi there! I have a "0" file named in my root directory. what that file is used for? it's empty file.
