Notes:

I'm a software engineer, currently working for Xplain Hosting, A drupal hosting specialist, as Senior Drupal specialist. I was probably the first person to use Drupal in New Zealand!

I'm also very interested in web applications, for which I mainly use Eiffel. The most interesting class of web applications are business process systems, in which I specialise.

I'm also busy with Eiffel free software projects. I maintain the Cetus Links Eiffel pages.

Just had an ancient HP ProLiant dying on me: simultaneous failure of a memory bank, and a hard disk. Luckily hard disks were mirrored, phew.

As it was urgent, I bought a server I could pickup: an IBM Express x3100 M4. Warning: do not get this server. On a good day the thing takes 5 minutes to get to disk boot! Very time consuming to get that going. Also needed to apply an urgent firmware update, but no clue how that worked. Tried to run the IBM UpdateXPress ibm_utl_uxspi tool, but somehow that didn't seem to want to work on Ubuntu. Tried everything to get that going, booting OpenSUSE disk, booting SUSE EnterPrise Server 11 rescue disk, simply didn't want to work.

In the end I discovered that I had to use the IBM Bootable Media Creator utility. Doesn't run on Ubuntu. So installed a supported OS, SUSE Linux Enterprise Server 11 via my VMWare Workstation tool, and could then run BoMC. Once you know how updating firmware works, it works quite well, but boy is this hard to figure out. Took me a day of trying things, before I hit on this. And five minute boot times don't help. The IBM readme's are written by lawyers, not for people in a hurry.

This IBM X Server is apparently nice with something called Integrated Management Module II, but couldn't get that going, because I needed an activation key which I didn't have for some reason. I'll email IBM support, see if helps.

Pity I was in a hurry else I would have gotten a System76 or IX Systems box, they just work without getting in the way.

Always had lots of issues playing back HD content over minidlna or mediatomb to basically any player, i.e. my Android tablet/phone or chromecast: just stuttering all the time. First thought it may have been BubbleUPnP, or MX Player, but once I got a phone that had 5G I could confirm that the problem disappeared on 5G. Had read people saying it was WIFI interference, but didn't believe them as it didn't appear the case when checking WIFI networks with WIFI Analyzier. But what do I know, once I switched my channel from 1 to 6 all my issues disappeared. Just weird, performance of channel 1 was usually not a bottleneck (could download at 9MBits easily), but probably there was indeed enough congestion to cause stutter. Very happy to have this fixed, makes DLNA so much more enjoyable.

Weird issue with Apache 2.4 and the geoip module: geoip didn't properly detect the remote address, even though the remoteip module was enabled and working. Had to recompile the geoip module to get it too work. Bug in earlier version of issue with Ubuntu 14.04 perhaps.

Weirdest error today with printing. Upgraded my FreeBSD (source recompiled of 10.2p6), after that wanted to print from my recently upgraded Ubuntu 15.10 desktop. Didn't want to print, got: "Filter failed" in cups jobs screen. First I thought it was due to the FreeBSD upgrade, but after a while I figured out an Ubuntu 12.04 laptop still printed fine, as well as a PC-BSD 10.2 laptop.

Error messages on FreeBSD cups server were not very helpful, with things like:

(/usr/local/libexec/cups/filter/rastertopdf) stopped with status 1.
Or
prnt/hpcups/HPCupsFilter.cpp 530: cupsRasterOpen failed, fd = 0
Anyway, after I discovered it must be my recently upgraded Ubuntu 15.10, and I probably hadn't tried to print after that, tried to remove and reinstall the printer. That didn't help. The final magic was a suggestion:
lpadmin -p HP-LaserJet-cm1415fnw -m raw
After that thinks worked, weird, weird, weird.

Continually see this in svn 1.8.11 server log currently:

Provider encountered an error while streaming a REPORT response.  [500, #0]
A failure occurred while driving the update report editor [500, #103]

Get this when doing a checkout/update. Client says:

svn: E120190: Error retrieving REPORT: An error occurred during authentication

Many reports of same problem over many years over the internet. No solution.

The only thing that works is svn 1.6 client. Go figure.

Setup is apache 2.2 server, wandisco latest 1.8 svn, and svn repository is nfs mounted. But that doesn't matter, even when making the repository local it doesn't work.

Upgraded my Ubuntu 14.04 Trusty Tahr to the WanDisco 1.8.11 from 1.8.8, doesn't help.
