@ewwhite I bet it is the same thing. That ewwhite guy marked it as a duplicate, so it must be.

Mark Henderson

@HopelessN00b He's a bit of a douchebag though. Not convinced he knows his shit

Falcon Momot

@FalconMomot Yes, the kernel can use it to cache files. The kernel can take memory away from the JVM if it has a better use for it. That's how pretty much every modern OS works. The alternative to using RAM is wasting RAM. The OS has a memory manager specifically to ensure RAM goes to the best purpose. Arguments like "Java applications eat up all my RAM" almost always indicate an admin who doesn't understand how modern operating systems use RAM. — David Schwartz 7 mins ago

I am being lectured on kernel VMM

Mark Henderson

@FalconMomot Mansplaining

HopelessN00b

@MarkHenderson Well he does prefer HP equipment, so you know there's at least something wrong with him :)

Falcon Momot

can we call it "chumpsplaining" in this case?

Mark Henderson

00:10

@HopelessN00b We all know that SuperMicro is the master race

HopelessN00b

@FalconMomot I'd endorse that the term for this case, yes.

@MarkHenderson Not gonna get into the vendor wars, as I think they're more or less about as good... generally no better or worse, just slightly different PITAs and fuck-ups. That said, because of HP's recent activities and decisions, it needs to be mocked and lose business, lest their asshattery spread.

Mark Henderson

@HopelessN00b HP are the reason that I get massive discounts at Dell

Because for some reason Dell think that we spend $150,000 year on HP equipment and are trying to lure us away

HopelessN00b

A displacement discount?

Mark Henderson

@HopelessN00b The R710's that are selling on eBay at the moment are selling at 3 years old for the same price we paid for them brand new

So I'm going to say yes

Falcon Momot

And by the way, the answer is page faults. Think about that for a moment, and a disk-bound application, and tell me again that wasteful userspace allocations have zero performance impact. — Falcon Momot 33 secs ago

I think I'm going to stop talking in those comments now... enough is enough.

HopelessN00b

00:18

@FalconMomot Yeah, he can get really... um... pedantic... or miss the forest for the trees or however you wanna say it. Gets zeroed in on one specific technical detail or use case, and can't see the rest of the world because of it. Not gonna get much out of further conversing with him.

@MarkHenderson Fuck me. I'm gonna have to call up our Dell rep and see about getting another Dell for home if they're giving them away that cheap to HP customers.

Falcon Momot

oh god he holds a senior position at a democratic payment systems company

"chief cryptographer"

Ripple Labs

The company Ripple Labs is the creator and a developer of the Ripple payment protocol and exchange network. Ripple Labs was founded in 2012 and is based in San Francisco, California. == History == Ryan Fugger conceived Ripple in 2004 after working on a local exchange trading system in Vancouver. The intent was to create a monetary system that was decentralized and could effectively empower individuals and communities to create their own money. Fugger later built the first iteration of this system, RipplePay.com. Concurrently, in May 2011, Jed McCaleb began developing a digital currency system...

Mark Henderson

@HopelessN00b We had a bit of an "in" in that a friend of a friend was a product manager there who entered us into the system, but now that we're in we get all those discounts

Falcon Momot

@FalconMomot The kernel doesn't need to know the RAM is "free". The kernel always has control over the use of RAM unless the application locks pages. It just has to make the mapped pages discardable to get the RAM back. If the data is unmodified and unused for a period of time, and I/O bandwidth isn't saturated, it can opportunistically write it to swap, making the pages discardable, allowing it to reclaim the RAM as soon as it has a better use for it. (This space isn't large enough to explain how modern memory management works, but it seems like you have some very common misconceptions.) — David Schwartz 2 mins ago

lol, yup, I totally have no idea about how x86 memory management works, and that's how I implemented the x86 processor in software.

oh god, he worked for the NSA.

on "encrypted storage and messaging systems".

HopelessN00b

Hmm, never heard of it. Sounds like a better designed system than BTC, though I notice they have the same shitty "business model" (if you can even call it that) most of these digital currency companies do.

Falcon Momot

I'm starting to really dislike this guy.

HopelessN00b

00:26

> I would have to say that I’m most proud of the time I spent consulting for the NSA in 2001.

HopelessN00b

^That's pretty alarming, at the very least.^

@HopelessN00b: Not everyone is in the "Lets do exactly what the commies did" department.

@JourneymanGeek ...not sure how to take that...

Journeyman Geek

@FalconMomot: aww, it clearly wants to hug the guy in its mouth with its headtentacles

Falcon Momot

:P

Journeyman Geek

@HopelessN00b: There's reports that some intelligence agencies are simultaniously exploiting tor and patching those same exploits

Falcon Momot

unrelatedly: large monsters chasing down small individuals for food can't be energy-positive.

Journeyman Geek

@FalconMomot: Its great exercise tho

Falcon Momot

@JourneymanGeek that's adaptive. lots of people don't patch, so you end up being able to own people.

HopelessN00b

00:28

TBH, everyone I know who's... erm, let's say "consulted" with the NSA (or had any direct contact with their people) has been extremely unimpressed with their technical capabilities.

Falcon Momot

and then there is the additional upside that you can blame them for getting owned.

Journeyman Geek

Thats different

Falcon Momot

@HopelessN00b +1 - most of those that I know don't say they are proud to have worked with them, except in relation to certain very specific things.

to trot out that you are proud to have worked with the NSA is to impugn your moral character.

Journeyman Geek

I thought you were talking alarming evil competent stupid, as opposed to full blown evil empire incompetent stupid.

HopelessN00b

Maybe is was different back in the day when NSA stood for "No Such Agency," and maybe I'm just feeling nostalgic, but intelligence services that get discussed publicly are already failures.

Journeyman Geek

We're supposed to have moral character?

Q: Windows 2003 Dual Nic Gateway server

I'm trying to configure a Windows 2003 server with two interfaces as a gateway. I'm looking to have this server as a gateway to another network which has an internet gateway. Nic 1: 172.16.0.0 (internal Network and DNS,DHCP server on same box) Nic 2: 192.168.0.0 (Interface to network with Intern...

Who the fuck is deploying Server 2003 today?

Falcon Momot

@JourneymanGeek yes, when you run a company like that, and ask people to trust you, one hopes.

HopelessN00b

@JourneymanGeek Well, we're supposed to claim we do in public, at least.

Falcon Momot

@MarkHenderson people who belong in jail.

Journeyman Geek

@FalconMomot: in theory, my loyalty goes as far as my contractual obligations, and my paycheck. Unless I actually like you. ;p

Falcon Momot

00:32

god, can there please be people in this world that think before they talk, and that actually want the world to be a better place for everyone instead of merely a more convenient place for themselves?

HopelessN00b

NO! Bad Sysadmin! Don't deploy a new system that's already almost EoS. — HopelessN00b 20 secs ago

Journeyman Geek

@FalconMomot: They probably exist

Falcon Momot

I know a few but not very many

HopelessN00b

@FalconMomot Wouldn't that be nice. Let me know if you find one. I can probably sell a real unicorn horn for quite a fortune. :p

Mark Henderson

@FalconMomot Also: People who use Windows Server as a routing box

That's why we have actual routers

Journeyman Geek

00:33

@HopelessN00b: and a nice bridge, only slightly used.

Falcon Momot

@MarkHenderson yeah I was going to comment that there and then decided there was no point

Mark Henderson

@FalconMomot Yeha I had a 3-point comment but backspaced it when I read @HopelessN00b's comment

Journeyman Geek

eh, Now that my home server is back up, I probably should start tracking down the very fun issue with my other nic

Mark Henderson

@JourneymanGeek I can confirm that Server 2012 R2 Core on an Intel NUC runs sweet

HopelessN00b

@MarkHenderson And even if you're gonna undertake the dubious exercise of using Windows as a routing box... you should at least do it right, and use a version that comes with RRAS. Duh.

Mark Henderson

00:34

(well, as sweet as a shitty processor with almost no ram can)

Journeyman Geek

@MarkHenderson: meh, that thing beats up my current home server and takes away its lunch money.

HopelessN00b

Oh, and forget Ripple, I've decided it sucks.

> Depending on the type and degree of interaction a user has with a gateway, the gateway may have Anti-money laundering (AML) or Know your customer (KYC) policies requiring verification of identification, address, nationality, etc.[2] Such policies are designed to prevent criminal activity.

Journeyman Geek

(and is like lower wattage, and smaller)

HopelessN00b

Kinda defeats the purpose of a decentralized currency if you're going to let centralized authorities control how you use it.

Journeyman Geek

also, 4gb is 'almost no ram' in something that small? ;p

Mark Henderson

00:39

@JourneymanGeek Welllll most physical servers that i deploy are 128GB+ and most VMs are 8-16GB+

Journeyman Geek

@MarkHenderson: and are at least 2U?

Mark Henderson

@JourneymanGeek 2u

Journeyman Geek

Yeah

I'm half curious if someone's going to end up doing something like that colo that runs mac minis and rackmounts nucs ;p

HopelessN00b

Yeah, I've had more than 4 GB of RAM in my desktops and laptops for... shit, I can't even remember. Been several years, though.

@JourneymanGeek Probably. Someone's set up a colo business for Raspberry Pis, believe it or not.

Mark Henderson

@HopelessN00b I had 4GB 10 years ago. I've always been a memory hog

I remmeber I had 256MB in 1998

When my stupid lame mates only had 32MB

Journeyman Geek

00:45

lol

~3 years with 4gb on my laptop (and a year and half or so with 16 on my desktop I think). Before that I had 2gb on a desktop, and 1gb on a laptop

ewwhite

@Kate Perfect.

Kate

I just can't imagine pulled pork with cheese on it.

Mark Henderson

@Kate Pork with cheese sounds horrible

Kate

agreed.

ewwhite

01:26

@MarkHenderson What's your backup solution of choice these days?

Falcon Momot

Oh, a good sharp cheese in moderation is great with pork.

ewwhite

(Windows environment)

Mark Henderson

@ewwhite Veeam

Oh

ewwhite

Is it particularly expensive?

(it's a VMware environment with Windows and Linux VMs)

Mark Henderson

@ewwhite $750/socket for up to 6 sockets

And it does all the shit that VMWare SRM does

ewwhite

01:28

looks like I have 2 sockets for this site...

It's a single host ESXi installation, but managed by my central vCenter

Mark Henderson

So it will do backups, but also ship the off-site to non-like storage arrays and do failovers. It has native Equallogic and Lefthand connectors for direct-san based backups

There is a fully functional free version for 2 sockets, but the backups can't be automated or scripted (you have to click the button)

ewwhite

I don't really have a target location for backups...

Mark Henderson

But it gives you a good chance to trial it and see what it can do

@ewwhite I backup to disk

ewwhite

a pair of 900GB disks in the same server as one destination...

Mark Henderson

And replicate off-site

ewwhite

01:30

and an RDX drive I could potentially use

Mark Henderson

The catch with their off-site replication is that it leaves an open snapshot on the VM for the period between the replications

Whereas SRM leaves a SAN-level snapshot open

For regular backups, it snapshots then deletes the snapshot so it's all good from that perspective

ewwhite

I have a lot of vSphere replication and ZFS-storage replication experience... so it's interesting to see some of the functionality duplicated in Veeam.

Is there an agent VM that handles things?

where do you install it?

Mark Henderson

@ewwhite You install veeam on either bare metal, or as a VM inside your cluster

And then you point it to your vSphere installation

And if you have a compatible SAN you give it the login details to the SAN

ewwhite

What about for a standalone ESXi host?

Mark Henderson

I don't know

Allegedly all good

veeam.com/kb1777

ewwhite

01:34

Well, I'm going to try... gulp

Mark Henderson

I've been pleased

Twice I've had it leave a snapshot open indefinately, but I think that's my fault because I interrupted the backup procedure incorrectly

ewwhite

@MarkHenderson Thank you for the recommendation.

I never had the chance to try it, so this will be a new thing

Mark Henderson

01:50

@ewwhite No worries. I literally just got this email from their marketing too

@MarkHenderson Incredibly cheap, yes.

@FalconMomot What?

Falcon Momot

don't break them.

Jacob

@FalconMomot I didn't, it broke it's self.

Falcon Momot

mhmm

Jacob

02:13

OH and I really want to steal your monitor

Falcon Momot

@Jacob do not steal my monitor. Also I think there is a spare one on andrew's desk.

my monitor is verbotten.

Jacob

It's small tho :(

Falcon Momot

too bad!

get budget for a bigger one!

Jacob

You never even go to the office

Falcon Momot

I was actually there last night until about 0300.

if we are honestly out of displays, go requisition some more.

Jacob

02:16

@FalconMomot So there is the one on andrew's desk, but I want a bigger screen.

Falcon Momot

so do I, but we don't always get what we want :P

Mark Henderson

@HopelessN00b Too bad I don't need one

Jacob

@FalconMomot That's not how I recall you ending up with your current monitor :P

HopelessN00b

@FalconMomot Damn, even I'd steal that. Looks like an improvement over my 27" IPS screens.

Falcon Momot

I believe it is 81"

HopelessN00b

02:19

@MarkHenderson Meh. It may be incredibly cheap, but it's still a tape deck... tape, blech.

@FalconMomot What kind, and resolution, if you know? Anything special, or "just" a run of the mill 1080p screen?

Falcon Momot

anyway, @Jacob, you can't have it, it's on my desk, and I use it for things like showing 4 VMs at a time, or running IDA. Find your own stuff or requisition it if we don't have it; I'm not playing musical IT equipment.

@HopelessN00b idk

HopelessN00b

Heh, I love musical IT equipment... somehow I always end up with the best stuff, and lots of it. :)

Jacob

@FalconMomot Someone sounds angry.

Falcon Momot

also all those giant graphs I've been rendering lately.

yeah, people keep picking petty fights with me ;)

Mark Henderson

@Jacob people keep trying to steal his monitor

Jacob

02:22

@FalconMomot It's not a fight, it's not like I was going to steal it.

Falcon Momot

not you.

HopelessN00b

@MarkHenderson Serves him right for having an 81 inch monitor, if you ask me.

Falcon Momot

@HopelessN00b if only!

Mark Henderson

@HopelessN00b What a cunt

Jacob

@MarkHenderson Nah, what's really happening is people are trying to tell him that they are more qualified than he is.

Mark Henderson

02:23

I'd steal his monitor too

Falcon Momot

I have a 2560X1440 27" one in Canada, but it's my personal stuff

Jacob

@FalconMomot I might just buy a personal one, it's on 130$ for the one I like

HopelessN00b

@FalconMomot Oh, nevermind, then. If people don't like their monitors, they should work from home. :)

Falcon Momot

@Jacob requisition it first. you shouldn't need to buy your own hardware if you have a legitimate use for it and it's cheap.

HopelessN00b

@FalconMomot Yeah, I got 4 of those at home. Love it. Now I just need a telecommute job so I can utilize them all to their full potential. :)

Falcon Momot

02:24

@HopelessN00b yeah I have one at the office and one at home

the one at home is getting lines, unfortunately

Jacob

@FalconMomot My understanding of that process is to email {boss} and say can I haz plz?

Falcon Momot

that's a good way.

Jacob

I will after chicken and I fix the server that died today.

HopelessN00b

:( I was able to pick them all up for $400 at Microcenters at various times. At least they're not ridiculously expensive like the 27" 1080p ones were at first.

Mark Henderson

@Jacob A good time to ask for shit is right after you've fixed someone elses shit

Falcon Momot

02:26

mine were from Korea and cost about $250 canadian.

Journeyman Geek

@FalconMomot: oh, the IPS ones Atwood was crazy about?

HopelessN00b

Ah, yes, the Korean IPSes. I came too late to that party, but didn't mind a whole lot. Still a hell of a deal at $400.

Falcon Momot

@JourneymanGeek I think so yeah

Journeyman Geek

I keep wanting to steal the ex-office projector, but I can't find anywhere to use it on

@FalconMomot: Kinda wanted one or two, but yanno ;p

I think one of the other SU mods has one, maybe two of em ;p

(mods, not monitors)

Jacob

@MarkHenderson Naw, my boss was like, "Just tell me where to spend money" I think he's just happy to not have to deal with it himself.

Journeyman Geek

02:30

@Jacob: that's pretty awesome actually

@HopelessN00b: I figure when 4Ks come around, they'll either price drop, or you'll see similar things with 4k monitors

HopelessN00b

@JourneymanGeek Yeah, hard to say. The first available IPSes were the Korean ones and they were dirt cheap... which is pretty counter-intuitive, so who knows what'll happen with the next generation of screens?

Journeyman Geek

@HopelessN00b: those were basically the panels apple could/would not buy ;p

Even then, they beat the crap out of anything else in a few ways

I kinda want one of these dx.com/p/…

IPS, fairly small, likely to get you pulled out and cavity searched if found in your luggage.

Jacob

@FalconMomot you wouldn't happen to have a blacklight would you?
