@CircusCat did you want to test anything on Atom-ZFS? I can give you access to that server if yo uwant

@Bob No, just your general impressions on performance

@CircusCat It's not really a heavily used server... I don't think there were any perf problems on the CPU side, but everything was slow (thanks, HDD)

@CircusCat If you want to run some benchmarks or chuck a heavy load on there... I'll give you a user. I've already moved off that server anyway.

@Bob What was your maximum throughput? Do you find it mostly disk bottlenecked not CPU bottlenecked?

@Bob Thanks for the offer. Would be nice though I've not got time right now (sleeping on a friend's sofa atm because reasons)

@CircusCat lemme know when and give me a public key

Just wanted to get a gauge of how suitable that Atom storage server board might be for ZFS use

@CircusCat I'll do a quick seq test with dd, one sec. also, it's a single drive - no raidz, no mirror

@Bob Ah

I've got a vague feeling ZFS can scale to number of cores approximately equal to number of drives

Not sure what'd happen if a single CPU core/thread can't keep up with one drive though

well, this sucks

dd if=/dev/urandom of=/dev/null bs=4M count=1000 is ~65 MB/s

so /dev/urandom would bottleneck before the drive :P

lol

I need uncompressible test data... hmm.

This is why I usually use /dev/zero for dd benchmarks

@CircusCat I have compression on

Obviously only works with compression off :-P

actually, I'll make a dataset with compression off

3.7 GB/s on /dev/zero

@Bob You can just set compression off on an existing dataset too

@Bob Don't tell me you have dedup on too? :-o

# zfs create -o compression=off tank/test

started at 1.1 GB/s, thanks ARC :P

dropped to 190 MB/s before it stopped, trying a larger count

@CircusCat nah, I don't use dedup

3.7GB/sec is interesting though, that would suggest CPU limited throughput (checksumming, etc.) would be at least that

thought about it before, but these servers don't have that much RAM

@CircusCat dropping very slowly throught 130 MB/s

@Bob CPU usage?

40 seconds later 120 MB/s

pretty sure that's the disk bottleneck

@CircusCat load average 1.9

dd itself using ~13% (one core?)

That's not terrible

I wonder how much that board actually costs now

wait lemme show kernel threads

@CircusCat also this is on the previous gen... C3xxx should be a fair bit faster

your CPU is probably fine, at least on the ZFS front :P

@Bob Nice, thanks

No RRP published on that board, but a very interesting concept

16 Atom cores, 16 SATA ports, dual 10GbE and dual 1GbE... optional PCIe 3 x8, built in OS drive

@CircusCat I do wonder how it compares to some of the newer AMD stuff

but AMD doesn't seem to be targeting low power

@Bob The processor performance probably won't come close, I mean it's Atom.

But AMD doesn't have integrated SoCs with 10GbE and so forth

@CircusCat sorry, I meant price

@Bob Ah

Though the theory is AMDs new arch does scale very well to low power

Thing with pricing is even on a cheap AMD platform you're still having to bung on a 10GbE card and/or AIC SAS controller

ah yea

Last time I saw a mainboard with 10GbE built in (Xeon D based IIRC) it came in at a lower cost than a Xeon E3 + a cheap 10GbE card

In fact it came in at lower than some 10GbE cards on their own

@CircusCat wasn't the Xeon D itself cheaper than the E3?

@Bob Probably

E3 also never comes with the option of an integrated 10GbE controller

Especially not at 45w

10GbE seems like a difficult thing to integrate

I suppose there's an amplifier stage off-chip though

It's SFP+ so no actual transceiver on the chip or the board

Which might make it easier

AMD's new core is pretty competitive but where they're behind is that it's just a core. If you want something integrated, compact, and efficient, well AMD don't make 10GbE cards.

All that on an AMD board you'd need both a full ATX board and a bunch of AICs. Thoguh you can get server ATX boards with on-board non-SOC 10GbE chips

@CircusCat oh, not an integrated port

@CircusCat don't worry, just use thunderbo- ohwaitthat'sintel

and it's not even easy to find on intel boards :\

@Bob I wonder if I can find a server board with it

Cause my laptop does have Thunderbolt 3, as does sorta my old desktop board which isn't mine anymore

tomshardware.com/reviews/samsung-t5-portable-ssd,5163-2.html

> The number of low-cost portable SSDs has grown significantly over the last several months as SSD vendors continue displacing HDDs. The attack began with desktop and mobile PC's and is now spreading into removable storage products. It seems like two or more portable SSDs show up at my door every month. I thought we were supposed to be in the middle of a flash shortage!

rofl

@CircusCat 10gbe isn't really mainstream/om die on the desktop no?

@JourneymanGeek 10GbE hasn't even been broadly available on desktop boards until very recently, when Aquantia launched the AQtion NICs.

yup

though technically mad people enthusiasts have been getting second hand enterprise cards cheapish for a while

Also, 10GbE switches are few and far apart in consumer space.

at this point though, you could bug together something off spare hardware

(I'd be happy to have proper gigabit. Work is fast ethernet entirely. Home is homeplug, which is starting to annoy...)

hm. I have an annoying one here. Chrome does the aww snap. for everything. even about:crashes

tried a full reinstall, tried removing it (with revo) and reinstalling....

hm. might mbam scan in the morning on mon

@JourneymanGeek remove the profile

tried that too

lol. zipped and deleted the google appdata folder for the user

its also system wide

the computer is just ****ed a bit

office politics is fun

Boss tells me to set the printer to scan and email through my account since we switched ISPs and cannot use the old ISP SMTP server.

Did so, and suggested we set up a seperate account for that... to the director.

director ignores it. HR suggests its not confidencial enough.

things get done.

so I have to politic a bit ;p

@JourneymanGeek send an email to your immediate boss suggesting that, and let him handle it?

lol crap

I'm backing up some old servers (buyvm) before cancelling them

this one has a 2.1 GB auth.log

apparently logrotate on Ubuntu 14.04 was broken

hm. it's also got a samba server running

I don't remember that

hm

I have a server here that ... doesn't appear to be doing anything

huh. I found a backup of an even older server ... sitting in /root/.ssh/

@Bob naw, director asked immediate boss to do it. Who passed it down to me

just create seperate account, tell boss it's done? :/

that'd what I'd have done in the past for stuff like that

morning

@djsmiley2k for historic reasons, the director is the one who controls creating email accounts

which is the lulzy thing

So, he asked, then HR complained, then he wanted it fixed after hours. I fixed it the moment I was asked, shortly after I came in

first appraisal was ok. Great technical skills, need to show more initative, and be less of a slob.

Boss claims a few folk are making fun of my tamil accent behind my back and I talk to fast but shrug

also, apparently cause politics, I shouldn't refer to him as my boss ;p

which is lulzy but whateves.

@JourneymanGeek ...then what are you supposed to call him? :P

Apparently by name.

@JourneymanGeek wear a shirt? :P

I have no idea. I also shouldn't actually tell people he dosen't want me to do things that's not my job, but not do things that's not my job

Ignore that, he is online :)

@Bob I do. But it gets untucked... a lot

@DavidPostill Wasn't it policy to only consider duplicates by question asked?

On account of walking a hell of a lot

@JourneymanGeek Sounds like you need a better belt :P

well, my pants are too big

I lost 3kg since I started this job

is that stress related or just all the exercise?

Will a domain controller provide NTP for non-domain client machines?

it should, from what I understand?

@Burgi all the exercise

I get fat when I'm stressed

are things slowly calming down or are they still as crazy as ever?

crazy as ever

(I think?)

actually its pretty quiet today

when i was an engineer we wore black polo shirts with the company logo on because of all our crawling under dusty desks, etc

made you could get your company to do something similar

@Dave @DavidPostill I've left a couple comments...

@Bob @Dave Reopened.

Thanks @Bob.

Thanks @DavidPostill,

@DavidPostill Thanks.

brb deleting the scheduled task before I get logged out next time :P

How is everyone in this room

wouldn't have stopped me as a teen :P

@Dave same as always, I suppose

which is good. lack of drama is always good.

he he, no it woudln't stop but I think in this case the OP is asking because the child is forgetting more than being disobediant.

he he he, I have a wife and 2 daughters... it's always drama :) Then I curl up into a world of IT and code and feel like I'm in a happy place. Topped off with an hour of guitar... bliss :)

lol

I've got chat on a side bar... your guitar is tiny and shoelike.

;p

hides

@Bob superuser.com/questions/62525/… and some redirects should take care of that.

@DavidPostill yup, but @Dave's answer seems to handle it too - putting the delay in the task vs in a long-running batch file

Maybe just s/shutdown/lock/

since I'm on psudomobile... linkie?

@JourneymanGeek . superuser.com/questions/1242116/…

hometime

ah

I have 30 minutes to go

my guitar... is not.... :)

kotaku.com.au/2017/07/…

lol

the legends of the interwebs

@Dave did you smash it in a rock and roll style?

I would not do such things :) ha ha. Although I knew some one who did smash his guitar on stage because next day he was leaving to live in America. He got to American border and explained he was on holiday, they searched his bag, found a card from his mother saying "good luck with your new life in America", so they turned him back! What a twit!

oops! :)

just hilarious :)

is the 28th a bank holiday?

It is indeed

I guess this means a day of cooking with the children making a massive amount of mess

@Dave cooking with the kids can be fun. I usually ask the oldest to lit-up the bbq

less work to do

he is even baking and cooking the chocolate cake. Not bad for a sixteen years old.

sounds brilliant :)

Although I'm really really bad at cooking cakes

I guess because I don't like cake

I think it will be a BBQ tomorrow so we can have pizza...

there is a hurricane due to hit manchester on sunday

south of stoke is meant to have insanely good weather...

this is yet another indication of the london-centric weather planning from the government

o_O

sudo su

555

sudo -c /bin/bash su -c /bin/bash

;D

/bin/bash not found. :)

lol

:O

i just learned of this groups existence a couple minutes ago, cant believe the name never stuck out before. maybe im finally a super user now lol, when life adds u to sudoers.. lol

life has added you to sudoers?

do people make you sandwiches when you ask?

lol huh

im usually the one cooking for others

oh i get it

sudo !!, just need to be a bit more affirmative is all

Would you kindly make me a sandwich?

i like to compare ego perception and higher consciousness to root vs non-root user.. as far as my cs understanding extends. i'd retract the idea that something external gave power... i say i was root all along, but tricked to believe otherwise

o_O

you were never root

you still aren't

sudo doesn't give you root.

Root giveth, root taketh away.

@Bob kk.org/cooltools/daiso-dollar-tools ;p

@DavidPostill got an appointment with the office

Two hours from now

Any tips?

relax

understand they are clearly interested, else you wouldn't be using their time

remember their time, is their money, don't waste it, don't rush it.

have some water, in a bottle, or a cup

something you can sip on, especially if you need to think/calm down for a moment

hm

@JourneymanGeek ~6k steps on a normal-ish day for ~5km :P

I need to walk more

10432 today for 6.6km

and I'm slacking today

I think maybe 500 of those steps were from typing :D

@JourneymanGeek ehhhh. those screwdrivers remind me of the old $2 shops. they're horrible to use :P

I've gotten much nicer sets off ebay

lol

cable ties are also a bit meh - aldi has/had nice assorted packs for something like $4 for 500

their normal screwdrivers are not bad

the drill driver bit was nice though. I got some of those from daiso :P

haven't seen the wire brushes. I need them

hm. need that paint knife too :P

@JourneymanGeek they're very much meh

the handles are :(

can't apply much force, and hurt to do so

@djsmiley2k okay, thanks!

And also, I've been offered jobs due to enthusiasm. They went through a list of skills, I think I had exposure to about 30 - 40% of it, but I explained it's just a matter of learning it all @rahuldottech and got the job. It's better to be honest than try and make out like you know everything! :)

Also i don't think this is for a job, it's for sponsorship for his project

but yeah, what @Dave said counts.

Oh I see :)

@Dave thanks, will keep this in mind!

@Bob I really like their replacable headed ones
