hmm

apparently puredarwin had its first new release in 3 years ;p

Oliver Salzburg

I really wish it would be brighter. Like, intensely bright :D

@OliverSalzburg Is that some tasty pi?

Oliver Salzburg

@Paul Yeah

I wanted to quickly try controlling the blink1 through Node on it

Then I found out that compiling Node takes 2 hours on it

Then I found out that they provide binary downloads for the Pi...

1.5hrs into the compilation

Journeyman Geek

lol

@OliverSalzburg: that's that the GPIO pins are for ;p

Oliver Salzburg

@JourneymanGeek The beauty of blink is the simplicity. But I guess the GPIO pins aren't exactly rocket science either :D

Journeyman Geek

1:00 AM

they arn't ;p

Oliver Salzburg

Well, I bought the things, I should do something with them :D

So now I'll make the Pi listen the network for certain UDP broadcasts and change the light on the blink. Yay

Journeyman Geek

lol

planning on using mine as a torrent downloader

(sad, I know)

Oliver Salzburg

:D

Humm, maybe I should use the GPIO pins and actually learn something useful :\

Use the GPIO pins to broadcast a radio signal

toad:/home/hennes/work/rPi_FM_radio>cat URL
http://www.icrobotics.co.uk/wiki/index.php

Steps to play sound:
sudo python
>>> import PiFm
>>> PiFm.play_sound("sound.wav")
Now connect a 20cm or so plain wire to GPIO 4 to act as an antenna, and tune an FM radio to 100.0Mhz

Oliver Salzburg

Sweet

1:17 AM

I am not sure how legal the example wav file is in their download.

But as someone with a car radio with poor FM and ancient tape I am considering a FLAC to FM project

2:01 AM

@Hennes Damn that is cool.

Aye.

My car doesn't have bluetooth or any aux in the radio. So if you want to use something external... you can't

Now I can play music through my pi

"We will include example hacks of how to turn the blink(1) into a USB keyboard and mouse emulator." Uh? An led that emulates a mouse? Am I missing something?

Journeyman Geek

its a microprocessor, so I guess you can just make it pretend to be a mouse or keyboard and randomly move stuff around? ;p

2:18 AM

@Paul Right now I use something which looks like 'head-phones to tape'.

Before I had a ncie CD player. Car got broken into. CDs stolen

3 months later it got broken into again.

I never had anyone break in when I drove a car with an ancient radio though

2:50 AM

40% of OpenBSD installs lead to shark attacks. It's their only standing security issue.

I feel like that trying to use iTunes

wish you a very happy birthday, @williamhilsum! Have a great year ahead!

That seems like a neat script.

I have a modest monitor height.

8:36 AM

@JourneymanGeek @Sathya looking at your SO migration discussion, I wonder if you're now getting the full benefit of the crap that used to be sent our (SF) way on top of the crap that SO always sent your way anyway.

I also wonder at what point someone at Stack Exchange will actually realise "OK maybe it's SO that's the problem here, not the other sites that are grumpy". I've even seen programmers.SE complaining about the migrations from SO.

I think that some of the problem the problem is that its fairly easy to get a decent points total, and privs, on SO without actually becoming *involved…

8:55 AM

@Sathya oh? happy birthday @WilliamHilsum!

fffffffuuuuuuuuuuuu

Also, came back to this:

Journeyman Geek

9:26 AM

@RobM pretty much that. Maybe they need to have fake posts and take away migration rights for that, like they do with the review thing.

@JourneymanGeek taking yourself out of their migration list would do from your point of view, and if SU is happy with that then that's great. God knows we haven't missed them on SF. But yeah, it's fixing the symptom rather than the problem.

What's wrong with my windows?

It's not resizeable :P

Oliver Salzburg

@Bob :D

there we go.

I'm bad at clicking tonight :\

Oliver Salzburg

Well, now I finally got that update

Yesterday it was this i.imgur.com/fB4jDvC.png

...screw you, Java.

Oliver Salzburg

I uninstalled it completely like two weeks ago, but required it for "some website"

11:13 AM

@OliverSalzburg It's hiding its name... Must be a virus! Seems legit.

Oliver Salzburg

@TomWijsman :D

Disappearing text and non-re-sizable windows, what's going on there? :S

Oliver Salzburg

The disappearing happened only after I wanted to screenshot the window actually

And the resized UAC dialog was waiting for me when I turned on the computer

TIL about MSFT's Home Use Program - Microsoft Office Professional Plus 2013 for $10

@Sathya :O

@OliverSalzburg Oracle seems to have learned not to let people screenshot :P

Q: Location of The Below Mentioned IP Address and the domain name

I would like to know the exact location of this IP address 127.0.0.1 along with the domain name if possible and under whose name it is registered. If you can provide me with the address from where it is operated or even the area, would really appreciate.

windows-7 windows windows-xp networking windows-8

is this a joke?

Oliver Salzburg

Well...

My initial research concludes that it is in fact not a joke

@JourneymanGeek #gemsfromstackexchange

11:43 AM

This IP address seems to be operated by Kamal Khokhani, click on that link to get all known information about that person. — Tom Wijsman 11 secs ago

Also, the amount of windows tags... :O Fixed! :D

@OliverSalzburg: Erm... Read his profile's "about me".

Oliver Salzburg

@TomWijsman Nice :D

Not sure how a 10 years of experience QA that worked at IBM and got certified by Verizon ISP and another company not know about this.

Journeyman Geek

this is why phone support sucks ;p

Oliver Salzburg

@JourneymanGeek :D

12:16 PM

@TomWijsman quite a.. history, that

12:27 PM

@TomWijsman If that's anything typical of QA, that would explain a lot.

Journeyman Geek

and this is why @Sathya, @jokerdino and I complain about the quality of indian IT professionals so much ;p

@Sathya After five months on my new job. I accidentaly found out I have access to Microsoft Dreamspark where I can get free copies of Windows 8, Windows 7, Visual Studio 2012 Premium, Office, etc etc etc

@ruda.almeida wow

let me check if my workplace has that

@ruda.almeida Isn't DreamSpark educational use only?

Oh, wait, BizSpark.

The full name of the page is "Microsoft Dreamspark for academic institutions". Every product page says: available for "students/faculty/staff".

12:40 PM

@ruda.almeida > new job

I suppose I'm staff, but actually after 5 months I finally managed to get a login for the broken intranet and noticed a link, clicked on it and got an account on the MS dreamspark

you a teacher?

ah

Funny thing is, at my department we all use Linux and, institution-wide, it's a-mix-between-required-and-recommended to use only free/opensource software (not all departments follow this, but mine does, completely).

So I guess I will be using the software only on my home machines.

I hate it when schools require open source

almost as bad as requiring proprietary software

come on, let the student choose

(unless the course is that specialised, of course)

@Bob Actually, my countrie's government requires, or recommends, open source. I'm not sure. There's an open source fomentation policy and apparently if there's both proprietary and opensource alternatives we should use opensource

@Bob That's not for a course, it's for internal use.

Journeyman Geek

12:45 PM

yay!

@ruda.almeida ah, slightly different then

but still

Journeyman Geek

@Bob: I'm for platform agnosticness where possible

sure, use open source only if you wish, but don't force it on me - lemme choose whichever is more productive

Journeyman Geek

would have loved to have done linux forensics ;p

@JourneymanGeek eh. as long as its not Java.

Journeyman Geek

12:46 PM

ugh, ignacio should know better than to post oneliners

bad bad experiences there

It's like we should use Open Office on every staff PC institution wide. Lots of department choose to ignore it, however. I have to use linux, but it's cool because I'm learning cool new stuff

Journeyman Geek

@Bob: the problem for me is most forensics courses assume windows suspect systems ;p

@JourneymanGeek gets quite hot <-- numbers please

Journeyman Geek

lol

I basically poached his answer

with some easily googleable stuff

12:48 PM

@ruda.almeida Open/Libre Office. Urgh.

Love the idea, hate the execution.

Journeyman Geek

lol

OOo/Lo has a ass backwards layout in writer

also, lacks citation generation

Also, Java.

Oliver Salzburg

:D

I'm actually amazed by how little memory MS Excel uses with rather large spreadsheets

Journeyman Geek

lol

@Bob: protege ;p

12:51 PM

@JourneymanGeek Hm?

Journeyman Geek

it manages to slow to a crawl on my gaming desktop

java app. does knowledge management

really cool. sucks performancewise ;p

@JourneymanGeek o.O

how much RAM does that machine have?

I assume at least 8GB

Eh. Freemind.

It was a school requirement at one point.

On those first-gen Atom netbooks they gave us.

Also rather buggy. Want to insert an image? Well, I'll throw an error after displaying a progress bar for 45 mins!

Geogebra is a nice one. Usually quite smooth for a Java program :P

Does linux support 3TB drives natively?

I'm having a few issues on my windows machine

If it (the kernel version/build) supports GPT, I'd assume so

How can I find if the kernel version supports GPT?

Duh, Google of course.

GUID Partition Table

In computer hardware, GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. Although it forms a part of the Extensible Firmware Interface (EFI) standard (Intel's proposed replacement for the PC BIOS), it is also used on some BIOS systems because of the limitations of MBR partition tables, which use 32 bits for storing logical block addresses and size information. For disks with 512-byte sectors, the MBR partition table entries allow up to a maximum of 2.20 TB (2.20 × 1012 bytes) or 2 TiB−512 bytes (2,199,023,255,040 bytes or 4,294,967,295 (2...

I hope it's accurate

1:06 PM

@ruda.almeida cateee.net/lkddb/web-lkddb/EFI_PARTITION.html

Since 2.6.0.

@TomWijsman also assuming it was compiled with the option enabled..?

(Also, apparently it's possible to have disks up to 4TB with MBR in Linux.. but use GPT if at all possible. ugly hacks are ugly hacks)

@Bob

zcat /proc/config.gz | grep ^CONFIG_EFI_PARTITION > /dev/null && echo "You have EFI partition support." || echo "You don't have EFI partition support."

Again assuming you have support for /proc/config.gz. :D

Anyhow, I don't assume such things; I build my own kernel.

lol

1:24 PM

gzip: /proc/config.gz: No such file or directory =/

lol

@ruda.almeida And /proc/config?

(In which case you need just cat)

Not sure if /proc/config even exists...

Not on my machine

It could be that your distro doesn't enable that option.

@ruda.almeida If you're running a standard/common distro, it should be easy enough to just punch the version into Google

Which is unfortunate...

1:27 PM

Ubuntu 12.04

help.ubuntu.com/community/MacBook

Ubuntu works on Macbook so I guess so.

But I want to build a fileserver and I'm not going to use Ubuntu on my fileserver

cat /boot/$(uname -r) | grep CONFIG_EFI_PARTITION

I think.

hm.. I really need to get a Linux VM up on here

Journeyman Geek

you do ;p

oh yea, I have PuTTY. Good enough.

@JourneymanGeek I do?

Journeyman Geek

1:30 PM

yeah ;p

also 16 gigs of ram

64 bit java installed, with the 64 bit version of the program

the only VM I currently have access to is Win7

Journeyman Geek

it was just epic suckitude.

@JourneymanGeek 64-bit Java was even less stable last I tried -_-

@Bob That would grep the kernel binary... :D

whoops. what the heck made me think I would have access to /boot on an OpenVZ VPS? facepalm

1:31 PM

But yeah, some distros put it there somewhere, others might copy it to /etc/kernels

I have 33 different kernel configs there, joy. :D

o.O

Yeah, did a git bisect earlier...

@TomWijsman whoops

I think I meant

cat /boot/config-$(uname -r) | grep CONFIG_EFI_PARTITION

gimme a sec, I'm trying to start a VM over RDP :P

argh

I forgot, VT-x somehow got disabled on there

anyone here willing to try that command? :P

Oliver Salzburg

user image

Crazy stuff

@OliverSalzburg isn't that kinda redundant?

Oliver Salzburg

1:38 PM

@Bob I guess it isn't

Einsteins Grandson

hey guys

@Bob: Another option is to extract the config from the kernel with scripts/extract-ikconfig in the Linux kernel sources, if the kernel was compiled with CONFIG_IKCONFIG.

but a properly implemented hard refresh would not use the cache anyway

Einsteins Grandson

I have a cartridge HP LaserJet C7115X

Oliver Salzburg

@Bob It would if you asynchronously load elements after the initial page load

Einsteins Grandson

1:39 PM

How can I find out , to which HP printers I can put it in?

;o)

Is there a website with table of printers - cartridges compatibility?

@OliverSalzburg How do you bring up that menu ?

@OliverSalzburg :\

Oliver Salzburg

@HackToHell Right-click

I am not getting a menu, I am in the stable are you in beta ?

@EinsteinsGrandson h30094.www3.hp.com/product/sku/1757375/mfg_partno/C7115X

see near the bottom

Compatibility

1:42 PM

@Bob needs more url

I also don't get a menu, and I'm on rolling release.

@TomWijsman extension? :P

Einsteins Grandson

great

but how did you find it ou

t

I mean what if I am gonna be solving the same problem in the future?

...

Einsteins Grandson

what is the website where I put the name of the HP printer to see all the specs about it?

1:44 PM

I don't have any up to date 64-bit Linux distro image

Oliver Salzburg

@HackToHell No, stable

@EinsteinsGrandson Google :P

Einsteins Grandson

I mean what if I will be solving the same problem but for a different website

add site:hp.com to restrict the results

Einsteins Grandson

different printer

OK

Oliver Salzburg

1:44 PM

@HackToHell Version 24.0.1312.57 m

Einsteins Grandson

THANKX

or you could use HP's own search

it's surprisingly good

Einsteins Grandson

Which one?

a lot of manufacturer searches are useless though

Einsteins Grandson

what is the link?

1:45 PM

@EinsteinsGrandson Go to their website and search? :P

Einsteins Grandson

ok

for cartridge compatibility, the shopping pages are more appropriate

for which cartridges a printer uses, usually that's on both the printer's support/spec page and the shopping page

Einsteins Grandson

h10010.www1.hp.com/wwpc/us/en/sm/WF06c/…

it sends me to this website

which is different to yours

@EinsteinsGrandson there's multiple results

that's the one I got first too

Oliver Salzburg

@HackToHell Seems like it's only available if you check the Disable cache options in the developer tools

Einsteins Grandson

1:47 PM

whatever

@OliverSalzburg ...if you disable the cache, why is there a button to clear the cache??

Einsteins Grandson

I come here to ask you when I will have the same problem

;o)))))))

more appropriately, why does the button only appear when you disable the cache?

@EinsteinsGrandson sure :P

Oliver Salzburg

@Bob The option only has en effect while the developer tools are open

But the menu will be available even if the tools are closed

weird.

Oliver Salzburg

1:49 PM

It all makes perfect sense if you're a Chrome fanboy like myself

lol

FF here, remember :P

434 tabs and counting

Oliver Salzburg

I tried to forget about those ;D

@Bob Ah, seems I need to open the Developer Tools pane, I see.

And now the button looks perma-pressed, lol.

2:07 PM

the stock i5 heatsink

can anyone tell me if one of the clamps are "fixed"?

yay

one new VM up and ready

@TomWijsman @ruda.almeida cat /boot/config-$(uname -r) | grep CONFIG_EFI_PARTITION works on Kubuntu 12.04.

@TomWijsman does not exist :\

This needs standardization! :D

Or rather, distros not using different standards.

Apparently the /boot one works in RHEL 4 too

I don't have any other systems to test it on right now, though

2:31 PM

user image

is it "normal" to have one pin at a fixed position?

the other 3 pins can be moved up/down

Journeyman Geek

er, it simply means its locked in for some reason and you should unlock it ;p

@JourneymanGeek okay

the reason why I ask.. is this

user image

Journeyman Geek

o0

it arrived like that?

yeah it arrived like that

Journeyman Geek

postal 'inspection'?

2:39 PM

no, flipkart courier

Journeyman Geek

is the unit otherwise pristine? is there paste on the heatsink in 3 rows?

i'd try seeing if you can rotate that pin and seeing if it goes back into place

or were they supposed to be...

thinks

I fucked up my heatsink install

let me get a second opinion

hardforum.com/showthread.php?t=1615037

then you push them down to lock

IIRC

also youtube.com/watch?feature=player_embedded&v=nBae0TOdBqw

I wish I had seen that, I think I know where I fucked up ;p

@JourneymanGeek one pin seems to be fixed.. let me post a pic

also, mine's the 1155, 3rd gen proccy if it makes a difference

Journeyman Geek

that's not quite right ._.

its about the same install process

but yes the unit seems pristine

Journeyman Geek

can you rotate the posts?

or is it totally stuck?

2:50 PM

can rotate

Journeyman Geek

but dosen't go down?

yes

the others do, this one just rotates'

Journeyman Geek

hm

that's not good

some... gentle persuation?

user image

user image

the second pic is of the fixed one I mention

Journeyman Geek

thats stuck/locked down...

that is NOT normal

you should be able to unlock it tho

2:53 PM

user image

user image

these are the other 2

Journeyman Geek

ya, thats definately not normal

youtube.com/…

this goes against whats there on mine

Journeyman Geek

IIRC turning the locking posts puts them 'up'

yours seems to have one stuck 'down'

yes

one is pertually down
