Foor good luck

So Alfa Romeo race drivers put a cloverleaf on their cars for good luck. I think this needed a 21st century upgrade.

After 10 years of lease cars I am thrilled to actually OWN a car where I can slap stickers on or drill holes into it because… its MINE and no one can stop me ^ ^ (besides maybe the RDW)

ZFS and old hardware

I got my nands on an old Fujitsu MX microserver and decided to give proxmox a spin. Some notes:

4 x HDD from old laptops perform well without sync… use with caution and have backups.

root@proxmox:~# pveperf /XXX-raid/
CPU BOGOMIPS: 55998.56
REGEX/SECOND: 4163519
HD SIZE: 899.00 GB (XXX-raid)
FSYNCS/SECOND: 147.26
DNS EXT: 38.15 ms
DNS INT: 20.83 ms (home)

root@proxmox:~# zfs set sync=disabled XXX-raid

root@proxmox:
~# pveperf /XXX-raid/
CPU BOGOMIPS: 55998.56
REGEX/SECOND: 4173357
HD SIZE: 899.00 GB (XXX-raid)
FSYNCS/SECOND: 3986.33
DNS EXT: 39.74 ms
DNS INT: 21.05 ms (home

adding two SSDs in front of two slow harddisks have the same effect. (add them as ZIL for IOPS, add them as LOG to mitigate write delays / latency)

benchmark with pveperf first, then with fio

Mind your ashift. 12 == 4k, 9 == 512b

fastest way to zap disks to use them:
gdisk /dev/sda
'x' for extra commands
'z' for zap

upgrade time

nice example what some IKEA and a couple of days can make of a sad balcony

this year’s birthday project has been successfully executed.

the glowy stones are solar powered and are as useless as they are cool

rain

I don’t feel a thing
And I stopped remembering
The days are just like moments turned to hours
Mother used to say
If you want, you’ll find a way
But mother never danced through fire showers

I walk in the rain
Is it right or is it wrong
And is it here that I belong

I don’t hear a sound
Silent faces in the ground
The quiet screams, but I refuse to listen
If there is a hell
I’m sure this is how it smells
Wish this were a dream, but no, it isn’t

I walk in the rain
Why do I feel so alone
For some reason I think of home

The Seatbelts

The voice of Mai Yamane adds 20% more blue to this already sad piece. <3

Also: Pretty much my base emotion from November till March. Every year…

I immediately ordered a bunch.. that is almost as golden as the “Inshallah” stamp of a fellow consultant/project manager.

“if it works, it’s not stupid…”

#yolocolo attenuator – from twitter

“if it works, it’s not stupid” is the greatest shit the professional world has never needed and I am sick of it. This is not professional, it is maybe funny but it doesn’t belong in a business network. I can laugh about this on twitter but not on linkedin.

seriously, just go back to facebook or reddit or twitter. But pleaes keep this shit off linkedin.

I will block and unfollow all people who support, share or like this kind of crap from now on, zero tolerance.

Also: fuck you.

Mother should I trust…

fun error message that I received today.. citrix related (on Ubuntu 20.04, official citrix receiver install.. or workspace as it’s called now)

turns out the cert is valid, it’s just citrix looking in the wrong places. A simple symlink to the firefox cert store fixes this problem:

sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts

and another fix for a problem that I don’t really understand… :-/

shrink pdf scans for email

Scanning to PDF is kinda useful when signing a contract without being there physically but the file sizes are usually huge.

In my case a 8 page multipage file coming from xsane is ~12MB – which is a little too large to email back.

Luckily someone called Alfred Klomp has written a nice script that compresses the images inside the PDF using ghostscript. it is called… shrinkpdf ;)

The syntax expects a parameter after the destination file name, if not given, it defaults to 72 dpi which I found a little too blurry so I changed that to 120 dpi. A 2-page scan would then be 200kB which is still mail-able so my 8-page file became 1,2MB which is good for emailing and still looks readable. For archiving purposes I actually would keep the larger version.

so now to integrate this into an xsane workflow.. how to go about that?
