Ok, here is the deal. With announcing of new PS3 Slim and lowering price in US to 299$ i decided to get one from US. However our family budget is not expandable anymore due to finishing our house (furniture, building materials, paint, own, washing machine, endless list at all) I started little campaign to rise funds for PS3 (Slim). Now, if You find this blog and my job putted in editing it somehow usefull/etertaining/funny – please make little donation with the button at the right side of the post. PayPal will care of the rest. If You read this from RSS here is screen shot:

Wczoraj oficjalnie potwierdzono PS3 Slim wydanie PS3 Slim oraz obniżenie cen do 299$ za sztukÄ™ (299 euro w Europie lub okoÅ‚o 1350 zÅ‚ w Polsce – bogaci jesteÅ›my :/). Z tego powodu postanowiÅ‚em w koÅ„cu dopiąć celu posiadania tej konsoli. Aktualnie jednak nasz budżet domowy jest tak napiÄ™ty, że wiÄ™cej siÄ™ już nie da. Tak to już jest jak siÄ™ wykaÅ„cza dom. Niestety konsola nie ma posiada argumentów, że jest absolutnie niezbÄ™dna w nowym miejscu :) Dlatego też rozpoczÄ…Å‚em zbieranie drobnych dotacji na ten cel. Jak widzisz w tym poÅ›cie i w sidebarze obok (obrazek powyżej jeÅ›li czytasz przez RSS) jest przycisk i pasek postÄ™pu. JeÅ›li zatem wpadÅ‚eÅ› tu z wyszukiwarek lub jesteÅ› staÅ‚ym czytelnikiem i co wiÄ™cej uznaÅ‚eÅ› tego bloga za przydatny/pomocny/zabawny lub nawet przydaÅ‚ Ci siÄ™ do rozwiÄ…zania jakiegoÅ› problemu lub dziÄ™ki informacjom tutaj zgromadzonym zarobiÅ‚eÅ› mnóstwo kasy ;) – proszÄ™ przekaż dowolny datek mój szczytny cel :) PÅ‚atnoÅ›ci realizowane sÄ… za pomocÄ… PayPala.

Każdy kto przekaże dowolną kwotę zasłuży na moją dozgonną wdzięczność oraz zostanie wpisany w Hall of Fame (chyba że nie będzie chciał)

I got new HP Proliant DL160 G5 with three sata disk. For You interested in details here is a dmesg. Box setup wen’t smooth but disk operations performance was very low. Copy big file wrom disk to disk was around 6Mb/sec, fetching src from cvs stops from time to time for a while. To show how slow this is look how long take inserting backup of this blog to mysql again:

cancer@quad/usr/home/cancer[52]22:34#mysql -uroot -p cancerwp < /usr/home/cancer/cancer_blog_17.08.2009.sql
Enter password:
cancer@quad/usr/home/cancer[53]22:54#

Yup, 20 minutes and sql file was 85 Mb.

After checking dkctl against disks, I found (with help of morr) that write cache is disabled.

dkctl wd0 getcache
/dev/rwd0d: read cache enabled
/dev/rwd0d: read cache enable is not changeable
/dev/rwd0d: write cache enable is changeable
/dev/rwd0d: cache parameters are not savable

After enabling…

dkctl wd0 setcache rw
/dev/rwd0d: read cache enabled
/dev/rwd0d: write-back cache enabled
/dev/rwd0d: read cache enable is not changeable
/dev/rwd0d: write cache enable is changeable
/dev/rwd0d: cache parameters are not savable

… performance went to satisfying level. Copying is now about 40Mb/sec and restoring database above in less than minute.

Unfortunettly saving this settings is not possible for now.

dkctl wd0 setcache rw save
dkctl: /dev/rwd0d: setcache: Operation not supported

Maybe this have to be turned on in bios of server. For now i put cache enablers into /etc/rc.local.

System is NetBSD 5.0.1_PATCH i386 with FFSv2 and WAPBL.

Time to time comes need to update whole bunch of pkgs in NetBSD. Dealing with pkg_rolling-replace (which is very good script to update packages) I’ve found that sometimes it won’t update package when its dependencies are broken or missing. Unfortunettly I had some of this things like:

WARNING: No devel/p5-Compress-Zlib/Makefile - package moved or obsolete?
WARNING: No devel/p5-IO-Compress-Base/Makefile - package moved or obsolete?
WARNING: No devel/p5-IO-Compress-Bzip2/Makefile - package moved or obsolete?
WARNING: No devel/p5-IO-Compress-Zlib/Makefile - package moved or obsolete?
WARNING: No net/p5-INET6/Makefile - package moved or obsolete?

or:

security/py-denyhosts - py25-denyhosts-2.6nb2 missing
textproc/py-xml - py25-xml-0.8.4nb2 missing

The simplest way to resolve this is pkg_delete it, but when package is depend of other package or other package depend on missing package it’s hard to tell what You can delete first.

With help may come two packages:

pkgtools/pkgdepgraph: Visual representation of installed NetBSD packages
graphics/graphviz: Graph Drawing Programs from AT&T Research and Lucent Bell Labs

First, You have to generate file with Your installed packages:

pkgdepgraph > pkg

Then plot nice graph in png format:

dot pkg -Tpng -o graph.png

And here it is, my personall dependencies hell ;) (You have to view it in full size, becouse it’s to detailed to gave nice thumbnail – 2,5 MB PNG:)

I’ve not posted in English since a while. This entry will be a warmup. So here it is – my blog on fresh WP 2.7.1. Update went smooth enough so I not went offline. I also updated outdated plugins. Now have all grean plugins instead of 31 yellow :) One thing which is still riddle to me is that Wordpress claim to be 2.7.1 but still want me to update it to … 2.7.1 (see screenshot). Anyway, I didn’t notice any odd behavior so far. I think also speed of blog was slighty improved with upgrade. Also, with this upgrade I’m looking for new theme which will better fit to 2.7.1 (for example gravatars stops working now). Any recomendations? And last but not lease – new theme will welcome new visitors redirected from lama’s blog. I feel I win bet (RC4 on the cvs already :)

Unsure WP what version it is ;)
