@allquixotic IIRC you speak Spanish, right?
I am in love with this song
 
12:15 AM
@JordanRichards Did you raise a ticket with the hosting people? They at least need to confirm the underlying host is without issues.
 
@JordanRichards: if it reboots, there should be something about starting up. How do you know its rebooting?
and dmesg should/would never be empty
 
@ThatBrazilianGuy more like read/write... my spoken is very out of practice and very bad
 
@allquixotic Oh.
 
in order of ability: reading > listening > writing > speaking ;p
 
Well, I've never studied Spanish and barely spoken / listened to it.
But I can understand about 85% off the song
(Well, maybe the fact I speak Portuguese contributes to it ;)
 
12:26 AM
@JourneymanGeek I have just as bad
got new box booted @bob :D
 
Heh.... End user was having issues with monitors so she called the service desk. They nuked her roaming profile and then escalated the job as they couldn't figure it out.
 
@allquixotic: as do I
I hope to tame it with table +1
 
I need a decent mechanical keyboard :\
 
12:42 AM
@DragonLord: So, get one ;p
 
Money's very tight right now
 
so, put aside money you'd spend on starbucks one time a week ;p. You'll get there!
(I've cut back on junk food until my fun money budget isn't in deficit. Granted being able to spend that ahead is a luxury but I've quite literally put aside a tenner a week in the past to afford something I wanted)
 
@MichaelFrank Does it make any sense?
 
I might be able to do some freelance photography for the college beginning late this month or next month.
Pay's not great, but it's much better than nothing.
Hey, it's money from doing something I enjoy doing.
 
yup
lol
understanding music has never gotten in the way of appreciating it ;)
One of the bands I listen to do their better stuff in finnish.
 
1:16 AM
@ThatBrazilianGuy Not at all. It's literally two checkboxes under display settings to fix the issue...
 
1:33 AM
@DragonLord Sometimes the pay is way too low :(
Wife's studying photography
Courses are expensive. Equipment is ultra very super expensive.
Potential clients want to pay next to nothing.
 
@ThatBrazilianGuy: he's doing that a s a student job tho. and heh. I know a guy with a doctorate and a job as a researcher who is thinking of quitting to do that.
 
also, doing something that pays (at least enough to cover costs) is better than sitting around waiting for things to happen
 
Well, as my wife's still studying / starting, and she still doesn't have an impressive portfolio, she mostly picks small gigs for friends and acquaintances.
The "friends and acquaintances" part makes them often think they are entitled to paying next to nothing.
 
@ThatBrazilianGuy: so exactly the same as helping people with computers?
 
1:36 AM
@JourneymanGeek No, see, accepting a sub-sub-sub-par payment, in the long run, lowers the expected value for the market.
 
so... exactly the same as...
 
When I realized the market expects PC technicians to make wonders for the price og a Big Mac, I decided to quit.
 
(funny thing tho, I tell people to pay what I think my work is worth. If they don't pay me, or pay me too little, I don't bother to do it next time. Works REALLY well)
I don't work for kibble.
;p
 
1:40 AM
I don't even tell people I used to fix PCs.
Lately everyone and their brother has decided to become a photographer, so I see the same thing happening soon for photographers over here.
But, to be honest, I hear this complaint a lot from various acquaintances that work in creative / non-traditional professions.
So maybe it's a national tendency
"You're not a physician / lawyer / engineer / person with a real job so I won't value your work"
 
2:03 AM
@Bob for performance and saving time on recompiling ZFS, I went ahead and installed Lubuntu into the spare space behind the ESP on the flash drive :P
and because I have 2 HDDs and 2 SSDs, I'm using the SSDs for ZIL and L2ARC :D
 
2:18 AM
wow, ZIL makes it ridiculously fast
 
2:49 AM
@ThatBrazilianGuy: heh. IT's the OTHER respectable profession for indians.
however I'm still the blacksheep of the family for dropping out twice, and not being an engineer ;)
@allquixotic: meh. "The advice from many experts now" CITATION NEEDED
that said, I'm pondering adding something similar to pi hole, on a VM or phoebe, and I'd probably end up adding stuff like that
blah, left my headphones at work
and its quiet
er
at home
 
3:41 AM
The QoS on the new router seems to be much smarter.
Bulk downloads don't seem to hold up web browsing as much.
 
@DragonLord wonder if it implements CoDel AQM
 
@allquixotic Likely not. It's a Linksys E2500, which isn't a particularly advanced router.
 
3:59 AM
heh. I think I have the switch version of that.
 
The point is that this is better than the cheapie Chinese wireless AP we've used for several years.
 
._.
(most APs are made in china ;p)
and there's a few brands that arn't half bad (tplink for example)
 
True, but it was a very basic model.
Just a simple N150 AP with only one Ethernet jack.
Control panel's in Chinese with no alternative language options, and the router functionality is pretty limited.
 
ahh. So its better than a slightly bottom of the barrel, basic AP ;p
 
The E2500 isn't the fastest router (no Gigabit Ethernet, for starters), but it has the essential features expected of a modern router.
 
4:06 AM
(at the moment I have an asus, a dlink (which wierdly has excellent range) and a SE2500 switch)
everything is gigabit capable, but my 'trunk' between rooms is homeplug AV 1800, which despite the name, tops out at 300 mbps ;p
also, everytime I buy a router, I end up getting one free
 
Bob
@allquixotic what was wrong?
 
I see no real benefit to getting an 802.11ac router at this point. It's just too expensive, and our slow Internet service does not justify a high-end router.
 
@DragonLord: My ISP gave me one. I have no ac gear at the moment tho ;p
 
The E2500 is 802.11n dual-band, N300+N300.
Range isn't much better than the old AP, but it's serviceable when used with the existing range extender (Netgear WN2000RPTv3) in my office.
 
@Bob efibootmgr -d /dev/sde1 was my first attempt. needed -d /dev/sde
 
Bob
4:16 AM
@allquixotic LOL
Exactly the same thing I did!
 
so, I have 2 x 2 TB HDDs and 2 x 300 GB SSDs in this server....
I broke both SSDs into two partitions (same partition layout and size on each SSD): a 32 GB ZIL part, and "the rest" (more than 250 GB) as L2ARC.
 
Bob
Jun 9 at 23:18, by Bob
@allquixotic turns out efibootmgr defaults to /dev/sda and I need to specify a disk -_-
 
lol
almost but not quite?
 
Bob
ya
 
ZFS is so freakin' complicated ._.
 
Bob
4:18 AM
I didn't even know about the -d option
 
I then told ZFS to mirror the ZIL (for redundancy, since it's basically dirty writes)
 
Bob
@DragonLord ZFS is actually pretty easy. Root on ZoL, on the other hand...
 
@DragonLord: Well, its not a native FS
 
Bob
If you just want a ZFS volume, that's easy.
Once you try to boot from one, you're in trouble. On Linux, anyway.
 
so I have 2 x 32 GB partitions in a sort of awkward "RAID-1" as the write cache, and 2 x ~270 GB partitions with no redundancy as the read cache.
basically, the SSDs absorb any sort of IOPS limitations or throughput limitations of the HDDs, as long as you aren't writing hundreds of gigs at once.
 
Bob
4:19 AM
@allquixotic Hm... maybe I should've gone with that o.O
 
@Bob I'd probably just boot from an ext4 system volume which holds the OS and essential command-line apps.
 
and for reads, because L2ARC is smart, you rarely hit the HDDs
 
Bob
@DragonLord Then you lose the integrity verification of ZFS.
 
I probably get the same performance as you (you're using SSDs? right?) in almost all use cases
 
Bob
4:20 AM
IMO that's even more important than a drive failure you can restore from.
When some random file gets corrupted and you don't notice.
Better off having root on XFS, at the very least.
 
yup... checksumming is "here" for xfs, but none of the enterprise kernels (Ubuntu LTS, Debian Stable, RHEL7) have it yet
 
Bob
(or btrfs when it's finally stable)
 
checksumming for btrfs is in production kernels, but btrfs itself is still too wonky
 
Bob
@allquixotic You might even get better perf.
I'm using 3x SSDs on raidz1
 
eww
 
Bob
4:21 AM
So I might actually be limited by the parity calcs.
 
I had to start over with my volume entirely because I followed your instructions blindly the first time and made it raidz1... with two disks
 
Bob
ouch
 
@allquixotic Well, btrfs is considered stable for day-to-day use but some features may be incomplete.
 
Bob
yea, need to swap that out with mirror

Bob
4:22 AM
that was originally intended to document my own attempt :P
 
It's fine for a desktop, but I wouldn't run a server on btrfs. Yet.
 
logs is ZIL, cache is L2ARC
 
Bob
@DragonLord "stable"
(see above with crashes @allquixotic experienced)
 
btrfs is still eager to eat your data
 
Bob
...though, it's up in the air if that was due to btrfs or the hw raid card
 
4:23 AM
well I never got any kernel stack traces when the system would crash after switching to xfs
but maybe the stack traces on btrfs were due to poor error handling in btrfs
underlying storage dies in xfs -> it handles it with error messages and the kernel doesn't crash
underlying storage dies in btrfs -> kernel panic
 
Bob
@allquixotic Going through your updates - how'd you figure the 400MB limit? :P
That's the same I ended up on
 
because you told me
 
Bob
oh
 
lol
 
Bob
so it's still anywhere between 400MB and 4GB
(it failed on 4GB. I never tried ~1GB because I don't htink I'll ever need that much anyway)
 
4:25 AM
I just used the rest of the space on the flash drive for a rescue system... Lubuntu 15.04
 
Bob
Good idea.
 
that's got working ZFS, etc. on it
 
Bob
I might do that sometime.
 
don't have to recompile if I hose the main box
 
Bob
Should be enough to debootstrap one up without even having to reboot
 
4:26 AM
yup
but yeah, with no LZ4 compression (I opted out of that!) and ZIL and L2ARC, this thing screams... RAID1 instead of RAIDZ, no LZ4, so low CPU overhead... just 2 mirrors
the only CPU overhead is figuring out if the requested blocks are in cache
and then transferring from ZIL to the primary storage in the background periodically
 
What exactly is this dedicated server for?
Is the workload I/O bound?
 
everything
2
game servers, web servers, Cards Against Humanity, remote desktop to a general purpose Windows VM (KVM instance) hosted via Guacamole, file storage, Cavil...
 
Wow...
 
Bob
heh
mine is currently hosting znc, ffsync, gitlab, terraria
 
current box wasn't meeting my needs due to the frequent HW RAID crashes (monthly)
 
Bob
4:29 AM
still in the process of adding more
it's been rock solid so far
 
record uptime was maybe 32 days ish
 
Bob
root@debian:~# uptime
 04:33:39 up 54 days, 16:25,  2 users,  load average: 0.04, 0.07, 0.09
 
new box has no RAID controller. just two HDDs and two SSDs.
you never answered me @Bob, do you have the HDDs or the SSDs? since they're the same price
 
Bob
8 mins ago, by Bob
I'm using 3x SSDs on raidz1
 
4:30 AM
ahhhhhhhhhh
missed that
 
My little thing does a webserver (on a VM) ZNC
 
I think they cut down on the number of storage devices from 3 to 2 in the base configurations with Haswell
 
Bob
Bad decision. I didn't think about ZIL & L2ARC, and wasn't completely sure of what I was doing.
If I were to do another now? I'd copy what you did.
 
My Linode server is primarily for my website (House of DragonLord and The Dragon's Journal). It also holds a couple of private Git repositories acting as a backup for my most critical documents (namely college files and a subset of game saves).
 
I'm not even sure if they offered 2 x HDD and 2 x SSD on the Ivy Bridge servers
 
4:31 AM
I'm toying with throwing in a maiou instance
 
Bob
@allquixotic They did. I think I considered it.
 
It's just a single Linode 2048 instance. $20 a month.
 
(also, 1tb HDD, so I may consider throwing crashplan or something for backups)
 
it is more expensive, but keep in mind that I was paying for a hardware RAID card, which carries like a $25/month bill just there, so, removing the card and adding some disks is only $3/month more
 
(which is closer to a VPS than the monsters everyone else runs ;p)
 
Bob
4:33 AM
@DragonLord Using a dedi gives us more control and the ability to run VMs (or containers), at the cost of being far more expensive. And the more control means we need to spend more time fiddling with it.
 
also I might have linked this earlier today but while waiting for server to do stuff I've been completely entranced with watching her videos all day: youtube.com/user/bionerd23/videos
@Bob and having an IPv4 /27 with more than half of it unused, plus tons of free RAM and storage, means that I can often fire up a random box for whatever people need, as long as it's not CPU-intensive
with this new box, my limiting factor is really CPU... DDR4 kicks ass, ZIL and L2ARC kicks ass, so the only way this box is going to be bogged down is if someone pegs the CPU
 
(also, if I do IRC again scaleway.com/pricing looks tempting)
 
@JourneymanGeek pretty cool to have bare metal -- good for security
that's the cheapest bare metal I've ever seen
 
 00:36am  up 33 days  7:27,  1 user,  load average: 0.86, 0.27, 0.13
 
Bob
@JourneymanGeek ARM o.O
 
4:37 AM
@Bob not good for those use cases where something you purchase (or even FOSS stuff that's just really, really hard to compile) is like "here, download this binary :D"
# ./yay
yay: nope.
 
@allquixotic: hence IRC. You end up compiling everything anyway.
 
Bob
@allquixotic I cant find details on the CPUs either
ARM can be anywhere from a piddly always-on embedded micro to a beast of a Cortex-A72
(and even then x86 wins :P)
 
it's an ARMv7, apparently, all I can get from it
it's a quad-core ARMv7, so probably a smartphone-ish SoC.... if it's cheap, MediaTek, if not, Qualcomm or Samsung
 
Linode provides one IPv4 address and a /116 IPv6 address block for each instance.
 
4:40 AM
in practice it's going to be way faster than a smartphone though -- it has a gigantic heatsink, it doesn't need to worry about battery, and there's an SSD attached instead of a simple flash chip
 
Bob
@allquixotic A smartphone with an identical SoC/CPU. But we don't know which one they're using, and the available ARMv7 cores go just about the whole range.
 
1.2ghz processor, apparently typically used for NAS.
 
Bob
Could be looking at quad-Cortex-A7, or quad-Cortex-A15.
 
> e developed with Marvell a Cortex A9 ARM SoC offering excellent performances for web applications.
 
Bob
> High-performance, dual-issue, and out-of-order ARMv7 CPU with Floating Point Unit (FPU) operating up to 1.2 GHz (3000 DMIPS)
Wonder if that's a custom core.
Still, out-of-order so not a Cortex-A7
 
4:43 AM
> A C1 server gives a constant CPUMark of 12K. This is equivalent to an AWS M3 medium instance.
it's a Cortex A9. it's given in their server FAQ
 
Bob
Sounds like it might be a Cortex-A9
 
Bob
@allquixotic I should read your messages first :P
 
and mine ;p
(also, they charge around that much for ipv4 ips so....)
 
Bob
@JourneymanGeek well, you just said "1.2ghz", I was looking for the actual architecture
oh wait it was in the link
whoops
 
4:44 AM
._.
 
@Bob Looking at passmark CPU mark for Android devices, the Note5's Exynos 7420 is about 10x faster than the Note 3's Exynos 5420, in raw CPU performance (discounting memory and disk). Unfortunately, the Marvell Cortex-A9 they have at scaleway is closer to the Note 3's SoC.
again, the disk will be (much) faster, and the CPU might be better on certain workloads, and the RAM is probably DDR3 so that'll be faster than the Note3... but that still leaves a lot to be desired
it would be pretty awesome to see something like the Exynos 7420 run at full speed without the constraints of a battery, a GPU, pushing pixels to a screen, etc
 
Bob
@allquixotic But a m3.medium is a single vCPU
So they're saying this is actually 1/4 the speed for anything single-threaded
 
@Bob which is not at all surprising, considering the TDP, and also considering that Intel has always been the king of single-threaded perf, as long as I can remember
even a piece of an Intel CPU is going to deliver amazing single-thread perf
I'd rather take the single-thread, myself. If you have a multithreaded workload, the CPU can do thread interleaving. Or the scheduler can optimize out the context switches so well that it runs almost as if they were lightweight fibers.
But if you have a single-threaded workload that demands high throughput, you're stuck if you have 4 weak cores.
 
@allquixotic: tho, there's also what you want to use it for ;p
 
Cortex-A9, ouch.
That's a pretty slow core.
 
4:58 AM
lol
yup
 
Cortex-A53 is (slightly) faster, supports AArch64, and most importantly, consumes much less power.
Something along the lines of the Qualcomm Snapdragon 615 MSM8939 (Cortex-A53 4C@1.7GHz big + Cortex-A53 4C@1.0GHz LITTLE) would be ideal. If only there was a version for servers without the extraneous cellular functionality...
 
Bob
5:44 AM
wait we're on Linux 4.x? o.O
 
@Bob just a version bump for the hell of it
not an actual feature change
 
Finally retired my old Epson WorkForce WF-3540 after 32 months of use.
 
32 months isn't that long ._.
 
I'm setting up a WF-3640 in its place.
Yeah, not a whole lot of use.
The printhead is just too unreliable.
I'll maintain the new printer better.
 
5:57 AM
(my canons do about 5-6 years)
fair amount of use, tho we refill, rather than buy new carts
 
At least some parts, like the waste ink box and paper cassettes, are the same.
The print engine on the new printer is similar, but uses Epson's new PrecisionCore technology.
 
(and eh. I need to top up the ink on mine ._.)
Is that the one with the top-uppable ink tanks?
 
PrecisionCore is an advanced print head technology with extremely high native resolution (600 dpi, vs. typical 300 or 360 dpi) enabling high-speed, high-quality printing.
 
ahh, no
(likely to be my next printer. I refill anyway, and it would be less messy)
 
@JourneymanGeek If print permanence isn't a serious concern, have a look at the EcoTank printers. These have an integrated continuous ink system and come with two years' worth of ink.
 
6:01 AM
@DragonLord: Yeah, its not
90% of my prints are one offs
(but that's for when my current printer eventually dies ;p)
 
They have a high up-front cost, but you will save money in the long haul if you print a lot.
How many pages a month do you print?
 
lol
between 1 and 200.
Depends
(but... buuut... we've been refilling and that makes a ton of sense)
 
They're really only worth a look if you print at least 2000 pages a year.
 
@DragonLord: don't forget, overall lifespan for my printers are pretty long
 
Bob
Unless you do a lot of photo printing, you're honestly better off with a laser printer.
 
6:05 AM
@Bob: most of my printing is in colour ;p
 
My usage requires color printouts, both photos and presentations.
 
Bob
@JourneymanGeek Colour laser :P
 
@JourneymanGeek What about the HP Officejet Pro X series?
These printers are F-A-S-T. 70 ppm fast.
 
@DragonLord: 0-0
much too big
Most of the stuff there is printed out ;p
 
Bob
Actually, a modern colour laser is pretty good for photos too.
Won't compete with a photo inkjet (e.g. 6-colour), but it'll compete with a typical CYMK juuuuust fine.
@JourneymanGeek 404
 
6:08 AM
 
Bob
The main difference is how much you pay. A basic colour inkjet is $20. A basic colour laser is $80+. But the latter lasts far longer too.
(I actually prefer a colour laser for image printing... sharper lines and the gloss actually gets a photo-ish feel without photo paper.)
@JourneymanGeek Almost as messy as my desk :P
Currently using brother.com.au/products/printers/colour-laser-led-printers/… - was ~$120 retail at the time, and the starter toner is still going o.O
Been almost three years so far.

6:21 AM
Oh, I did replace the black toner once apparently o.O
I don't remember that at all
 
6:31 AM
@allquixotic: I even remember what that is
 
The new printer is giving me nothing but trouble.
The carriage seems to be jamming.
This is before I even put in the initial cartridges.
It's giving me different error messages (0xF1, 0xEA, 0xE8) and is reporting paper jams otherwise with nothing in the paper path.
Seems to be an issue with the carriage docking mechanism at the far right of the printer.
 
@DragonLord If it's new, take it back.
 
It's been sitting there for a while as a reserve printer.
It's still under warranty.
 
Consumer grade printers are not worth the time it takes to look into repairing them.
 
Seems to be a common issue with this model printer.
 
6:58 AM
@JourneymanGeek Wow, you hung pictures of yourself on the wall? Kinda weird!

Q: Epson WorkForce WF-3640 mechanical issue during initial setup; error codes 0xF1, 0xEA, or 0xE8, or "paper jam" reported with no paper in paper path

DragonLordI'm trying to set up a brand-new Epson WorkForce WF-3640 printer and it seems there are some weird mechanical issues. It would seem the carriage is not moving freely. This is before I get to install the ink cartridges. The printer may make a odd grinding noise and return errors 0xF1, 0xEA, or 0x...

LG Tone+ HBS730 Bluetooth Stereo Headset

^ My E6420 Dell came without bluetooth so I purchased 1 cheap Chinese. I wonder if bluetooth headphones successfully pair with Chinese bluetooth device. Actually my device does not have all features available because it works on generic Windows bluetooth driver. Yet it is said to work with licensed driver that certain company sells. Actually it's BlueSoleil software that costs like $20: http://www.bluesoleil.com/bssoftware/BSoftware.aspx
So what seemed to cost cheap in the end costs like normal bluetooth device...

Q: NTFS compression ate all disk space with no possibility to recover

VincentTo increase available space on a HDD (Windows Server 2012 Standard x64), I tried to enable NTFS compression on that drive. While doing the compression, it ran out of available space (despite having like 200GB on that HDD available at the beginning of the process). Compression process was interrup...

that sounds like a pretty serious bug
@bertieb wait, you expect to be able to do that? :P
 
@Bob Why not? :D
(I actually cannot connect in any way from this machine it seems, ping was just my first choice of troubleshooting)
 
cause I don't think android has a proper console, or a ping command ;p
