is confused

BloodPhilia

is confused about @MarkSzymanski 's confusion

studiohack

why @MarkSzymanski?

Mark Szymanski

Why does echo $SITE is $SIZE bytes return bytes//github.com/mrman208/http-size is 27526?

When $SITE is github.com/mrman208/http-size and $SIZE is 27526?

TomWij

What does echo "$SITE is $SIZE bytes" do?

Mark Szymanski

It should say: "https://github.com/mrman208/http-size is 27526 bytes"

BloodPhilia

12:04 AM

Where is this echoed?

shell?

some other programming language?

Mark Szymanski

From a bash script.

TomWij

@MarkSzymanski: I mean, try with quote marks.

BloodPhilia

mkay

Mark Szymanski

One second...

I'll put the script on Pastie.

Or, gist...

BloodPhilia

okay

Mark Szymanski

12:05 AM

gist.github.com/96cb7758ffd069b03bcc

Any ideas?

TomWij

Installing Cygwin xD

Mark Szymanski

XD

TomWij

12:21 AM

Bunch of command not founds, because I'm lazy.

But, it does show bytes//github.com/mrman208/http-size. :D

Mark Szymanski

Ah...

TomWij

Without your processing, I get:

https://github.com/mrman208/http-size is 123 bytes

Mark Szymanski

What do you mean "Without my processing?"

TomWij

SITE=$1
SIZE=123
echo $SITE is $SIZE bytes

:D

Mark Szymanski

Ah...

So..

It's a problem with the $SIZE variable.

TomWij

12:25 AM

Yeah

sed: -e expression #1, char 54: extra characters after command

Putting it on the same line, gives:

sed: -e expression #1, char 49: unknown option to `s'

Mark Szymanski

It doesn't do that for me.

TomWij

SIZE=$(curl -Is $SITE | tr '[A-Z]' '[a-z]' | sed -n -e "/content-length:\s*/ {
  s/content-length:\s*//
  p}")

Still has the problem, but doesn't give errors for me

Boom!

This is your solution:

SITE=$(echo $SITE | tr -d [:blank:] | tr -cd "[:print:]")
SIZE=$(echo $SIZE | tr -d [:blank:] | tr -cd "[:print:]")

It removes non-printable characters, as there seem to be characters in your string that causes it to start over from the left after it has printed the SITE.

Mark Szymanski

Whoo! ^^

Thanks! :D

TomWij

I've only got one error left: ./test: line 5: curl: command not found :D

nhinkle

someone i know said their printer was "spraying them with ink and spitting paper everywhere"

reminded me of this brilliant comic

Mark Szymanski

12:37 AM

Yeah xD

nhinkle

theoatmeal.com/comics/printers

studiohack

it is hilarious @nhinkle

Mark Szymanski

Very.

TomWij

@nhinkle: I'm looking to my screen from an angle that I can't see the papers fly from the printer... :D

nhinkle

@TomWij, lucky you

:D

this one's perhaps even a bit more applicable to all of us here:

TomWij

12:40 AM

Was weird when I moved and suddenly saw darker spots appear in that image...

A: Hello, can you fix my co...
B: No, sorry... But I might be able to answer your problem if you place it on Super User.

studiohack

@TomWij: so true...

nhinkle

Hahaha, so true @TomWij

I usually just tell people, "sure I'll fix it. I'm on duty at the helpdesk on mondays, thursdays, and fridays, from..."

studiohack

my biggest thing is the built in tech support for my family

they just don't know some of the most basic things...

TomWij

While I do love helping people, there are some that ask too much...

@studiohack Yeah, and instead of the bad way people use LMGTFY online, you can do it for your family and be happy about it.

Discussion about Cooking something in the kitchen? Fire up cooking.stackexchange.com. ^^

studiohack

yeah lol

nhinkle

12:48 AM

true. if i asked my mom how to do something with food and she said "just go look it up on cooking.se", i would be a) irked, and b) elated that she'd found cooking.se

but that won't happen

studiohack

I've seen cooking.SE. looks kind of out of place on the SE sites if you ask me... :P

nhinkle

i think there's some cool stuff there

i love to cook though so perhaps i'm biased :D

studiohack

yeah. and cooking is plenty technical, trust me

nhinkle

oh yes. it's a science, really

studiohack

I've cooked plenty of times myself. what do you like to cook the most, @nhinkle?

nhinkle

12:50 AM

i made this delicious chicken veggie stir fry pasta dish last night with some friends, made dark chocolate cookies the night before, and made french toast for people this morning

studiohack

wow, you're good! that makes me really hungry @nhinkle :P

nhinkle

i cook all sorts of things. i've got more experience with desserts and treats (I <3 pie!!), but everything's fun to make

studiohack

I've made bread for farmer's markets, and cookies, along with granola

have you ever made granola, @nhinkle?

nhinkle

i haven't made it personally, but i've had home-made granola and it is wonderful

we're actually thinking of making some sometime soon

studiohack

it is a lot easier than most people think to make

nhinkle

12:52 AM

see, my friends and i all live in the dorms, and we get sick of the dorm food, so every weekend (when we have time) we make food

oh yeah. a friend of mine's made it a lot before, so she's going to teach the rest of us

studiohack

I should take a photo of my recipe, and you guys should try it

that's neat! with college and all

nhinkle

yep yep. lots of fun. it's a good social event too, getting together with folks to cook

if you want to scan your granola recipe and post it i'll check it out sometime and let you know how it goes

TomWij

room topic changed to Kitchen Access: For all you Super Cooks out there

studiohack

LOL @TomWij

I've used this recipe many times, and its simple, that's mainly why i would share it

nhinkle

here's some stuff we made a couple months ago

i don't have any more recent food photos on my computer

it was a tasty rice and veggie dish

studiohack

12:56 AM

i usually don't take photos haha

nice photo though.

looks healhty

nhinkle

studiohack

what's that?

nhinkle

And here's the (slightly less healthy) apple cobbler we made later that evening

studiohack

looks good, I've always enjoyed apple pie/cobbler/etc @nhinkle

nice!

nhinkle

'twas tasty

we do try to make healthyish stuff, since there's a lack of it in the dining halls

studiohack

12:58 AM

yeah, to balance it out

nhinkle

^ blackberry pie I made a while ago

nomnomnom

studiohack

WHOA!!

that is so good, I'm going to star it.

:)

Mark Szymanski

Nice.

Double-star.

nhinkle

i had a little bit of help. my best friend is super into pies and even won an award at a pie competition once. i did all the work, but she guided me through the process

TomWij

Okay, I thought that picture was of low quality... >_<

nhinkle

1:00 AM

i've since learned to make 'em all on my own though :D

yeah it's not the best picture ever

TomWij

Triple-star.

studiohack

:D pies are yummy

nhinkle

it was totally the best pie ever though!

studiohack

you should make one with blueberries

nhinkle

been there done that :D

studiohack

1:01 AM

I've also heard of "shoofly pie" which is brown sugar and molasses - really good

nhinkle

don't think I have any photos of it though

TomWij

No, what I mean is that the thumbnail makes it look like the borders are pixelated, but you actually made it that way.

nhinkle

Ohhhh

Yep, the edges are crinkly

Mark Szymanski

Does anyone know what the difference between $* and $@ is in shell scripts?

I know they both access the arguments of a command, and I think they both refer to all the arguments, am I wrong?

TomWij

@MarkSzymanski: I have learned that... But forgot.

nhinkle

1:02 AM

Anyhow, I've gotta go. Getting dinner (in the dining hall, sadly) with some friends

TomWij

Isn't that Makefile knowledge though?

Mark Szymanski

SO to the rescue! XD

@TomWij: No, that's shell scripts.

studiohack

have a good one @nhinkle

nhinkle

thanks @studiohack

see ya guys later

TomWij

@MarkSzymanski: wiki.bash-hackers.org/scripting/posparams

They are both: all positional parameters except $0, see mass usage

studiohack

1:08 AM

hello @barlop

Mark Szymanski

Thanks.

barlop

@studio- have we met, or do you type hello to everybody in the room? that's a tough job you have, typing hello whenever somebody enters!

TomWij

Makefile has similar things but I think they are slightly different there.

Mark Szymanski

Yeah.

studiohack

@barlop: I do sometimes. I just said hello to you in particular because I've seen your name somewhere

on SU, that is. :-)

@TomWij, @MarkSzymanski: help me find the dupe question for this one:

Q: Use Laptop A with windows 7 as a monitor for Laptop B with windows xp pro & broken screen

Hello All, I currently have two laptops. Laptop A - Sony Vaio Model: PCG 71312L OS: Windows 7 Laptop B - Toshiba Satelite A105 OS: Windows XP Pro Laptop B's monitor has damaged and does not function. However, it can output screen on an external monitor as I tested it with an regular PC desktop...

laptop

TomWij

1:12 AM

nvm

studiohack

no synergy doesn't do that

TomWij

I need the other name that's stuck somewhere in my head...

studiohack

maxivista does

TomWij

But I know what you mean, I have retagged that question this weekend... :S

studiohack

but it is paid. synergy simply helps to use the same mouse and keyboard for two or more machines

TomWij

1:15 AM

Boom.

Q: Use laptop A's LCD as secondary monitor for laptop B

I have a working laptop (laptop A), but am interested in using the laptop's LCD as a secondary monitor for my main laptop (laptop B)...is there a way to do this via software or cabling without modifying laptop A? OS's are Windows XP SP3 and Windows 7. Update: Software must be free, and a bonu...

windows-7 windows laptop multiple-monitors

you like BOOM tonight, don't you @TomWij? ;)

TomWij

Yeah, I for once played Quake Live and used the Rocket Launcher a lot instead of StarCraft II, be happy that I don't usually use nukes with ghosts in StarCraft II as Boom would be my catch phrase every day. :D

studiohack

haha

Mark Szymanski

DANGIT

x.x

I can't remember how to close for loops in bash xD

TomWij

DONE :)

Mark Szymanski

1:19 AM

YES

THANK YOU XD

TomWij

:D

Mark Szymanski

I love how vim makes misplaced endings bold red.

Like misplaced fi, done, esac, etc.

TomWij

vim, I hear it so much but I feel like I don't need it... :(

Mark Szymanski

Why don't you think you need it, @TomWij?

TomWij

Well, I'm way too used to the usual way of working with text.

Mark Szymanski

1:22 AM

Hehe, I found this funny.

google.com is 219 bytes
github.com is 185 bytes
mrminimalist.nfshost.com is 3081 bytes

And yet, the third loads faster than all the others :P

TomWij

But...

Does it count all resources, or just the HTML?

Mark Szymanski

Just the HTML.

It just gets the Content-Length header.

TomWij

Google is 30.54 KB --> ~ 650 ms
Github is 549.32 KB --> ~ 2300 ms
Mr. Minimalist is 556.78 KB --> ~ 700 ms

Mark Szymanski

nods

TomWij

Github has way too much images on their front page... xD

Oh, that's not the problem.

Their CSS and JS file are both ~220 KB. :S

Hmm, but well...

Mark Szymanski

1:30 AM

@TomWij: Do you have a github account?

TomWij

It's nice to bundle the whole functionality so that it is only requested once and all subsequent loads will be much faster.

Nope...

Mark Szymanski

Ok.

TomWij

lol @ comments: superuser.com/questions/239774/…

studiohack

lol haha

hey @DanielBeck back again?

Daniel Beck

1:47 AM

yes, but unexpectedly

2:47 am local time

studiohack

wow @DanielBeck

KronoS

@TomWij gee... i don't know which one to pick

studiohack

you're way ahead of me :P

@KronoS: yeah, we're gonna close them all. haha jk!

TomWij

@KronoS: Well, the one I voted for is the oldest. Isn't the guidelines for closing that or am I wrong?

Daniel Beck

@studiohack You're on UTC-7?

TomWij

1:48 AM

Or maybe best?

studiohack

whatever that is @DanielBeck

if you're referring to EST, I observe that time sometimes. lol

@KronoS: we vote for the oldest.

@TomWij

Daniel Beck

@studiohack Saw that in your profile, yes

studiohack

yeah, I figured @DanielBeck

Daniel Beck

2:03 AM

Good night everyone, again.

KronoS

oh man... my body always has a negative effect on real mexican food...

night @DanielBeck

studiohack

night @DanielBeck, again :P

how is @KronoS doing?

KronoS

@studiohack doin good... just about to do some cleaning up of the SU site and then work on the resume

studiohack

sounds nice. i hear that mexican food isn't being nice to you. lol

KronoS

ya... massive heartburn...

I'm not one for the spices... but it just tastes so good.... even though it kills me later

digitxp

2:07 AM

Evening...

studiohack

evening @digitxp

what timezone are you in @digitxp?

@KronoS: do you have IBS?

KronoS

evening @digitxp

digitxp

Fun thing about chat is that you know you can just read the log and figure out what's going on and join in, but you don't because it feels stalkerish and you're lazy.

@studiohack Eastern

KronoS

I don't think so... but I really don't know...

not a doctor kind of guy... don't like them very much

barlop

how can I determine what process is making a sound ?

studiohack

2:09 AM

I read the chat transcript @digitxp

I learn a lot

no idea@barlop, but i've seen that question asked before

barlop

a paperclip just popped up telling me that!

but for win7.. not sure if it applies to xp

digitxp

@studiohack It's like watching the videotape of someone's convo before walking into the room.

studiohack

hahaha - I believe that is the chat easter egg

barlop

Q: What process is making that sound?

My Windows 7 system makes an intermittent ding sound (like a single chime, or bell). I don't know which process does it. So, my question is: Is there software out there that can tell me which processes are currently sending output to the sound device?

windows-7 sound alert

studiohack

@digitxp yeah...I watch people for a hobby though :P

KronoS

2:11 AM

@studiohack people watching is so much fun...

barlop

as if the intermittent sound wasn't enough.. for a moment i thought I had some malware, that paperclip popping up!

studiohack

trying to log into the SU blog but have already forgotten password @KronoS

KronoS

hmmmm. don't know what I can do to help... is there a reset option?

studiohack

I know!! @KronoS: that's why I want a degree in pyschology (@BloodPhilia), so that I can use that knowledge for my purposes :P

@KronoS, I'm resetting it, there's no problems, just letting you know that I'm on my way to read the draft.

KronoS

good... I want to have that posted... possibly even before the town hall meeting

no clippy, I don't need your help right now

studiohack

2:14 AM

Clippy! hey clippy! come here, @KronoS needs you desperately!

Q: How do I make XBMC the dashboard on my modded XBOX?

I have a softmodded XBox that currently boots to EvolutionX. I'm wanting to make the XBox a media server full-time, so it would be better if it boots to XBMC directly. What needs to be changed to have the XBox boot directly to XBMC. Thanks.

xbmc xbox

so I don't agree with closing this one...

studiohack

close!!

oh why?

KronoS

although it's an x-box in this situation he's debugging the computer side of things... and XBMC is something that we work with regularly

studiohack

its one of those iffy ones

KronoS

@studiohack exactly... I'm just not sold on the closure... yet... :P

digitxp

2:15 AM

@KronoS Does XBMC run on the 360?

studiohack

@KronoS lol

KronoS

@digitxp to my knowledge it does not... XBMC has actually pulled it's support for x-box's and moved onto just PC's

which now makes me believe this is not longer on topic...

good bye!

digitxp

It's chat...there is no topic @Kronos

Effing autocomplete never delivers on its promises.

KronoS

@digitxp no I mean the question in question lol

studiohack

topic changed to XBMC support crew

KronoS

2:18 AM

it still " bloinged " me

digitxp

I think the correct term is rubber banded.

studiohack

boing bong

KronoS

but bloinged just sounds so much better

@studiohack it's not a double sound... just a quickly reverberating one

studiohack

I refuse to be drawn into an arguement with @KronoS over rubber bands and boing bong

;P

fair enough... I will consent to a agree to disagree @studiohack :)

@digitxp awesome topic. shouldn't yell in here.

@studiohack Shh before someone from BoingBoing shows up.

KronoS

filling out a super hero resume for menial tasking jobs is such a bore... all of my experience is so... superior

digitxp

2:23 AM

And I've only used the thing 2 1/2 times.

KronoS

@studiohack ya you don't want to get me mad... this is what I do:

eat people?

KronoS

at least according to google images search

studiohack

@KronoS: is the blog title you're publishing titled "The Starting of our SSD Journey"?

KronoS

yes @studiohack

studiohack

2:24 AM

okay, just wanted to make sure I was reading the right one @KronoS

KronoS

ok... you can check all the others to make sure it's correct (grammatically and content)

studiohack

reading the blog, among many other things

@studiohack is all ears @digitxp

KronoS

@digitxp how's that...?

digitxp

is to use the Australian spellings so that they don't know what's right or wrong.

KronoS

lol

studiohack

2:28 AM

depends if you have an austrailian or american spell checker :P

digitxp

@studiohack Best part is that they can't tell if it's Australian or British ^-^

My favorite so far is "gaol"

studiohack

which is goal?

lol

looks good @KronoS

KronoS

cool... maybe I'll even post tonight just to have it done lol...

I'll see... after I finish my resume...

that is one big gpu

studiohack

wow

digitxp

@studiohack jail

@KronoS Dem's small pickings compared to the ones dem dere aliens gots.

studiohack

2:36 AM

interesting @digitxp - learned something today

see vote to close @KronoS, anyone else around

KronoS

done @studiohack

digitxp

Say when's the election over?

studiohack

2 days, I believe

KronoS

in three days @digitxp

Hi

KronoS

hello @fahad

studiohack

2:49 AM

hi @fahad

fahad

Can anyone tell me about the computers memory?Everything that we do while we are working on the computer is stored in main memory.But I have confusions about which main memory

KronoS

you mean RAM?

Random-access memory

Random-access memory (RAM) is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order (that is, at random). "Random" refers to the idea that any piece of data can be returned in a constant time, regardless of its physical location and whether it is related to the previous piece of data. The word "RAM" is often associated with volatile types of memory (such as DRAM memory modules), where the information is lost after the power is switched off. Many other types of memory are RAM as well, including most types o...

fahad

cache,RAM and others

digitxp

@fahad Hard drive is permanent and holds the actual programs and your files. RAM holds the programs' temporary data and other stuff for fast retrieval.

fahad

What if we are adding two numbers so the temprary data would likely be stored in?

KronoS

2:53 AM

a few random bits on the RAM

fahad

wont it attempt to be stored on the cache first?

KronoS

probably... it really depends on the situation... what type of calculation is being made, how the program runs and how much cache and RAM is installed... but generally speaking I believe you are correct

fahad

Cache

In computer engineering, a cache ( in US/UK and in Aust/NZ) is a component that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. If requested data is contained in the cache (cache hit), this request can be served by simply reading the cache, which is comparatively faster. Otherwise (cache miss), the data has to be recomputed or fetched from its original storage location, which is comparatively slower. H...

Cache retrives data from the RAM so I was wrong and you were right

KronoS

Actually I take that back... now that I think about it, and read up on it... I don't think it'll be used in actual use of programs...

fahad

The most used data from RAM transfers to cache

KronoS

2:57 AM

@fahad incorrect... i believe its used for more baser operations

i.e. OS operations.. and possibly parsing of data from RAM to CPU and back

fahad

@KronoS: I am forgetting another type of memory location that exists.Which temprarily holds small amount of data....registers or something : (
