I used to know a mod who dated one of his users. She wasn't any trouble but apparently he told her that if she gets in any shit he'll either let another mod handle it, or quit being a mod ;p

allquixotic

@JourneymanGeek individual sites do have very particular and different cultures; anyone who thinks the whole network is uniform is failing to admit the truth to themselves, or they don't have enough experience.

i am wriitng another question - how to sensitively deal with members from opposing sides of a war

true - maybe "how to sensitively deal with arguments between members who are from opposing sides of a war"

Journeyman Geek

@Omen: If its not on scope for the site.... it just stays out

Omen

hmmm... yeah too simple of a question

Journeyman Geek

One of the sites I'm on just created a separate board for poiltics and shit like that, and stuck the most badass mod we had to handle it

niiiice!

2:28 AM

I'm so close to finally decommissioning my Hetzner server and putting a stop to the cash bleeding

then I'll just have my OVH box

Bob

lol

allquixotic

I finally went in and looked at the sparse images taking up more than a terabyte today

Bob

I kinda want to move, but I'm hardly making use of my current box

and paying 1.5x more just isn't worth it

also, higher latency

allquixotic

I had 3 images: one was a duplicate of one of the other two (366 GB gone); the other two were my previous Hetzner box, and my LayeredTech box, respectively

Bob

layeredtech? o.O

allquixotic

2:30 AM

@Bob back in 2006 or so they were decent

Bob

Hm. That 1920x1080 tablet is quiet tempting :P

allquixotic

I mounted the sparse images on the loopback device and went in and deleted a bunch of shit; now I'm tarring everything into a .tar.lzo which I'll then transfer over FTP

Bob

11" as well, but lacking a keyboard

allquixotic

I'm going to transfer loose files in .tar.lzo archives now, rather than disk images

I don't intend to ever boot from these again, just need the files themselves

a lot of the "used" space was free blocks that weren't filled with zeroes

Journeyman Geek

eheheh

@allquixotic: I did this with my dad's old laptop

Saved my ass today.

Bob

2:31 AM

but $350... for a Bay Trail

allquixotic

@Bob yeah, no

Journeyman Geek

Though, I only have one backup, this won't do ._.

Bob

@allquixotic eh, $300 to you

AUD and USD gap is widening

:(

allquixotic

@Bob a friend of mine, who's disabled and has diabetes but is a really good programmer, was up a creek when he moved and had no computer, so I bought him an HP ElitePad 900, used, off eBay for $399

this was a year ago so value the hardware a year more than you would now

it has a 64 GB eMMC SSD, 4 gigs of RAM, and a Bay Trail-M Atom

1920x1200 screen

also has an AT&T 4G card, which he actively uses

the verdict was that he loves it and it runs great

he bought himself a microSDXC card to stick in for extra storage, too

Bob

@allquixotic I'm looking at a poorer CPU and half the RAM

allquixotic

2:36 AM

@Bob -_-

Bob

RAM's probably the biggest issue

allquixotic

yeah for sure

Bob

and the eMMC is too slow to use for swap either

ah, screw it

if I want to play with a RAM-constrained Windows device, it can wait till the 1 GB RAM $65 tablets :P

allquixotic

@Bob is your main problem money?

Bob

@allquixotic well, considering this is primarily to play around with...

I can spend more if I really want, but I don't really want

allquixotic

2:40 AM

ThinkPad X140e is $700, with an AMD A4-5000, 4 GB of RAM, 128GB SSD, and an absolutely shit 1366x768 screen -_____-

proc's quite nice because of the Radeon graphics though

at that price point you won't find better

Journeyman Geek

@allquixotic: a lot of thinkpads have that res ;p

How many inches tho?

Bob

@allquixotic 15W TDP, ouch

and CPU perf on par with a Bay Trail-M (TDP 7-7.5W)

good graphics, but shit CPU

Radeon HD 8330, hmm

...I take back the "good graphics" comment

allquixotic

hmm, the new ThinkPad Yoga (Haswell) kinda rivals the Surface Pro 3

Bob

Intel HD 3000 is equal or better.

Except Bay Trail-M has a cut down version

4 EUs rather than 12, so significantly poorer

allquixotic

i7-4600U, 8GB RAM, HD4400, 1920x1080, 256GB SSD, 802.11ac

but that's $1500 -_-

Bob

2:44 AM

i.e. that AMD chip will beat a Bay Trail-M's GPU significantly, but fail against an i3

allquixotic

at that price you may as well get a Surface Pro 3

Bob

@allquixotic So about the same price as a SP3 :P

Except worse support.

allquixotic

except you don't have to worry about that damn keyboard detaching on you randomly

that's still a pet peeve of mine

Bob

I really want to see an Iris (Pro) in a convertible

Journeyman Geek

@allquixotic: physically or electrically?

Bob

2:46 AM

That's probably the biggest factor (aside from price) turning me off the SP3

allquixotic

@JourneymanGeek physically

Omen

I got funding!!!

Bob

I mean, come on MS/Intel

flagship hardware product

and put an average GPU even in the top model

allquixotic

2:52 AM

wow. for about $3300 you can get a 13.3" laptop that has performance on par with a desktop-replacement.

Journeyman Geek

@allquixotic: Razer or ~~dell~~ alienware?

Bob

@allquixotic Weighing about as much as a desktop, drawing about as much power, and venting hot air like a jet engine.

allquixotic

convergence is very nearly a thing. you can get two mSATA 1 TB SSDs, one regular SATA 2.5" 1 TB SSD, 16 GB RAM, a GeForce 860M, and a Devil's Canyon CPU (4910MQ). hella expensive though

@Bob true, true and true, but at least its form factor is small enough to fit in a (heavy) suitcase

@JourneymanGeek no. Sager/Clevo :P

Journeyman Geek

ahh

eh, sager/clevo builds some crazy ass shit

like the dual xeon laptop.

allquixotic

the specs themselves don't really impress me

my desktop is better in every way

it's the size of the system that impresses me, given its specs

Bob

2:54 AM

@allquixotic The CPU is almost there, but the GPU is still severely lacking.

Journeyman Geek

guru3d.com/news-story/…

allquixotic

@Bob how is an 860M lacking?

Journeyman Geek

@Bob: meh, that's probably good enough for most things

Bob

47 W TDP CPU is impressive, though, with that performance.

@allquixotic Worse than my 560

allquixotic

unless you're playing Star Citizen, you should be able to pull 60 fps for most AAA games on medium-high detail (maybe not 16x AA/AF, but high texture quality)

Bob

2:54 AM

about 30% worse

my 560 is now three years old

allquixotic

ohh I keep thinking 860 is the new Maxwell. that's the 960

Bob

and was mid-(high)-range at the time

allquixotic

Maxwell is supposed to be way faster

guess if someone were looking at a laptop like that, they'd wait for the 960M to arrive

guarantee that'd beat your 560.

Bob

@allquixotic 8xx is mobile-only

but judging by the comparative performance of the 980 and 780... not that much different

970 is about 1.5x the 770 though

@allquixotic if so, it'd be barely, I'd expect

much lower TDP though

allquixotic

I guess in order to properly build a desktop replacement laptop you STILL have to go for 17.3"

the 980M is out on the big boys.

that WILL beat your 560

Bob

2:59 AM

@allquixotic 980m, sure, but not necessarily 960m

870m is on par with my 560

allquixotic

hahaha they can do SLI in the 17.3" :D

Bob

880m beats it by 25%

I wouldn't want to be within a metre of the exhaust though

880m is 122W TDP

that's going to get crazy hot

my 560 is 150 W TDP

and can heat up a room pretty easily (and burn your hand if you reach down there)

allquixotic

wow; for a significant fraction of the cost of a new car, at $7251.01, the fully specced-out 17.3" Sager would have about the same CPU and GPU performance as my desktop, and much faster I/O because of it having five SSDs (two mSATA and three 2.5" SATA 6 Gb/s)

Bob

all that in a laptop needs some pretty powerful fans, and will get uncomfortable pretty quickly

allquixotic

I think I'd rather have 1/4th of a Prius Five instead

my desktop can stay right where it is

Bob

3:02 AM

@allquixotic and yet it's largely useless compared to the desktop + laptop you could get for that price :P

allquixotic

@Bob sigh. yes. unless there's that one week a year (or so) that I'm on vacation out of state and want to play Star Citizen

during THAT WEEK it would get... so much value

Bob

also, it might be powerful enough, but heat would still be a massive problem

SLI = two GPUs = 250 W TDP in a laptop

I wouldn't be surprised if it literally started a fire

allquixotic

@Bob how so? all you need is enough fans. two HD 7970s easily crank beyond 250 W in my desktop, and while it does tend to heat up the room, the cards themselves have no problem dissipating heat with a little bit of a kick from the fans

this is NOT the type of laptop you want to be gaming on away from a power source; you unpack it from your suitcase, sit it on a table, and plug it in

Bob

@allquixotic far less room for airflow

not much space for a heatsink

and the actual heat pumped out would be rather hot and coming out of limited vent ports

allquixotic

the more airflow you have, the cooler the temperature of the air.

Bob

3:05 AM

a desktop has far more room to move air, far more room for big fans, far more holes for air to go in and out

allquixotic

a condenser fan like on the original HD7970 can create some impressive airflow, like a turbofan engine on a plane lol

Bob

@allquixotic you wouldn't be able to hear anything over it -_-

allquixotic

@Bob oh well :D

Bob

(from personal experience with a 560 Ti and turbine fans... had to increase my headset volume about 10x and I could still hear it)

Journeyman Geek

That's what headphones are for ;)

Bob

3:06 AM

the speecs look nice on paper, but they're rather impractical - for reasons other than price

allquixotic

whoa, nice, in a couple of minutes (since I started typing actively in here the most recent time), lzop compressed a 14.9 GB tar file down to 10.0 GiB -- with the contents consisting of a vast array of diverse file types, from executables to jpegs to source code to movies and even some 7zip archives

impressed at the compression speed, while also having a meaningful compression ratio

O_O looking at iotop vs top, it appears that the compression is disk-bound

on a hardware RAID10 array of 4 x good enterprise HDDs

aaaand 15.3 GiB down to 6.8 GiB

I love this thing!

LZMA would've taken another 6 hours and given me a 4 or 5 GiB file instead of 6.8

-rw-r--r-- 1 root root  40G Oct 16 20:07 1.qcow
-rw-r--r-- 1 root root  14G Oct 16 20:07 1.tar
-rw-r--r-- 1 root root  10G Oct 16 20:07 1.tar.lzo
-rw-r--r-- 1 root root  95G Oct 16 21:44 2.qcow

-rw-r--r-- 1 root root 6.8G Oct 16 21:44 2.tar.lzo

finally pruning down all my junk to manageable sizes

135GB down to 16.8

~# du -h old-xfs.img; du -h oldest-ext4.img; df -h
566G    old-xfs.img
336G    oldest-ext4.img
Filesystem                                              Size  Used Avail Use% Mounted on
/dev/loop0                                              2.7T   57G  2.5T   3% /mnt/oldest-ext4
/dev/loop1                                              2.8T   13G  2.7T   1% /mnt/old-xfs

so that's 556 GB + 336 GB down to 70 GB once I tar everything

then it'll be maybe 80% of that (56 GB) once I lzo it

so in all, about 1.3 TB (566+366+dupe of 366) down to (56+6.8) = 62.8 GB

granted, that's with removing a lot of unneeded cruft, but I didn't go too detailed, just a lot of du -cks and removing replaceable files like /lib and /usr and /bin, then looking for enormous files and deciding if I want to keep them

there's still definitely tens of gigs of unwanted cruft in that 62.8 GB, but it's worlds better than what I was trying to keep before

Journeyman Geek

xz is efficient

lrzip may be better for huge files tho

allquixotic

@JourneymanGeek xz is a great space saver and it decompresses fast, but if you want to compress more than a gigabyte or so, the compression times are simply too long

never heard of lrzip

apparently lrzip can just use LZO in the backend, which is kinda silly :P

still interesting though

Journeyman Geek

3:26 AM

@allquixotic: its kind of a pain in the ass to install

and its apparently not cross compatible between versions

Bob

@JourneymanGeek A compression format that doesn't have a backwards-compatible reader is just stupid.

transfer from my Hetzner box to OVH box is running at about 2.5 MB/s :/ both supposedly have 100 Mbps ports

the OVH box's network is way better so I blame Hetzner for saturating their links

Bob

@allquixotic more likely just doesn't like EU => US

also consider running multiple transfers in parallel

that's what prompted this question actually

allquixotic

yeah, I figured it might be that. thanks

Bob

Your situation is a bit different, since you have a single large file rather than a lot of small ones. So less overhead.

But the intercontinental links suck anyway

Journeyman Geek

5:11 AM

@MichaelFrank: I'm a sucker for openworld games these days

Michael Frank

Oh ok, well let me know how it goes!

Journeyman Geek

and I love the whole idea of having persistent enemies

I hope my computer is up to it ;p

Also bought the new saints row game

Michael Frank

5:27 AM

...it's 1c cheaper to get the game and the season pass separately than it is to buy the bundle.

Journeyman Geek

(and sheeeeet. the game is nearly 40gb)

@MichaelFrank: o0

nope.

for me its 65 for the bundle vs 75 individually

We arn't using US prices any more tho

Michael Frank

Yea, I have to use USD.

$49.99 for the game. $24.99 for the season pass. $79.99 for both.

Journeyman Geek

o0

That means its cheaper for me in SGD than USD

Michael Frank

So wait... if the game has Gollum in it, then it's sorta parallel to LoTR. Which means that any effort made by you in this game doesn't actually matter in the overall Middle-Earth lore. :P

Journeyman Geek

@MichaelFrank: I think its roughly as out of canon as an orbital kerbal.

Also, gollum is insanely old

Michael Frank

5:35 AM

There's no reason not to make any LoTR games outside of canon. It's such an enormous universe.

Journeyman Geek

Its apparently set between The hobbit (movieverse wise) and LOTR (movieversewise)

Michael Frank

I did also read that they specifically didn't put LoTR in the title as they wanted it to be in the same world, but not the same story.

Bob

6:45 AM

@MichaelFrank we're priced in USD but not US region

it's probably cheaper in US region

Journeyman Geek

@Bob: we got our own pricing

Bob

@JourneymanGeek so do we but our pricing is (almost) always higher than US pricing and we have to pay currency conversion

Journeyman Geek

I think as of last month

Bob

they can't even use the conversion difference excuse since, y'know, we see the higher prices in USD

Journeyman Geek

Our prices seem to be the same or less ;p

Borderlands pre-sequel seems priced the same at current conversion rates

Bob

7:03 AM

@JourneymanGeek We get things cheaper than the UK at times. I don't think I've ever seen cheaper than US.

Journeyman Geek

Yeah, this was wierd ;p

Looks like nice softbox...

Psycogeek

8:07 AM

@Boris_yo why white? because most web pages are with a white background, so the picture of the product is the only thing on the stark white background. why soft? so there are no shadows , no 3D , or so the digital camera can get the shot because there is no contrast.

10 years ago, these same shots would have been done (in film) with some front light, and a lot of key light (~45* offset light) , more complex adding in some backlight to get higher contrast. That still works with digital. LED beware the lack of full spectrum of light, it can make some things look ghastly, especially the overly blue white leds.

White sheet , 2-3 lights and a chair :-) cheapskates softbox, with ability to adjust shadows, light and dimentional aspects, that would be ok for any consumer, until they have 300 products a day to process through a fast shoot.

i never really realised that most stuff is shot that way. When buying said products , the visual on the product is very important when stuck on the web for buying. If there was any enhancments that is often needed it is More pictures of the item, rightly i do not care what the background itself is, you would think that there might be more creativity in doing it. Ya dont do "portraits" of humans on a stark white backdrop (usually).

I wonder if it's related

rumtscho

10:24 AM

Hi. I wonder what would be the place to ask for troubleshooting a script I didn't write.

The problem is that it is in Perl, and I don't speak Perl, so if I post it on Stack Overflow, I don't know if I'd be able to implement any suggestions unless they include a straight code solution.

But if I ask it here, it would require somebody to do some programming, which is not really the place, is it?

And worst of all, wherever I place it, it smells of "give me the codes".

The problem is that I cannot afford the time to learn Perl before I get my real task done. I just want to use a working tool, period.

I got this one from a random web page, it promises that it will do exactly what I need... and then its output is broken.

Bob

@rumtscho Eh, if you want to ask in this chat, feel free.

rumtscho

@Bob I actually thought of the main page, but you're right, maybe people here in chat will know

It's this anonymizer, hopefully easy to understand for somebody who can do Perl

stephencuppett.com/wordpress/2008/06/03/web-log-anonymizer

When I run it, the promised .anon file gets created, but it contains just the string ORIG on one line. Nothing else. No log lines, anonymized or otherwise.

Bob

@rumtscho How did you run it?

And can you provide a log sample? Just one or two lines is enough.

also, note that this takes the sledgehammer approach

rumtscho

I ran it as perl webLogAnonymizer.pl www-survey_access.log

Bob

any sequence of four numbers separated by dots will be changed

rumtscho

10:32 AM

@Bob in what sense?

Bob

21345.245222.6356356.0 would count, as would 1.1.1.1, anywhere in the text. it'll change http://example.com/blah/1.1.1.1/foo as well

it just does a naive regex match

a better way would be to take the column that contains the IP as input, and only change that column

rumtscho

@Bob Hmm, interesting. Will a URL like this one match: /limesurvey/upload/surveys/882972/images/animal-line-example-with-circled-field‌s.png

Bob

@rumtscho no, needs to be separated by dots

        if (/([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)/) {

that's the regex

anyway, can you provide a log sample?
