Slackware64-current and udev 1.82

by on Jul.24, 2012, under Software

Some days after tinkering for a little bit you come to the realization that it might be better to stop doing anything with devices and just wait for the day to pass, because everything you touch breaks in the most spectacular ways. Of course this never stopped me from breaking even more, but I’m stupid like that.
Today is a day like that it seems. First our ADSL line at home received an upgrade to FTTH (aka a fiber connection), boosting our internet speed from a lousy 8Mbit down to 50Mbit down, and from less than 1Mbit upstream to 50Mbit upstream. (continue reading…)

FFmpeg versions and VLC 2

by on Jul.16, 2012, under Software

Another round of updates came along on Slackware64-current and since I was playing around with ffmpeg I figured I might as well update that. Since ffmpeg is one of those products that has a bunch of really active developers it gets updated about every 5 seconds.
This means that whenever they release a new version it’s instantly obsolete. However, that also means that when you’re trying to run the latest version from git, you’ll often run into software that uses the older functions/symbols/garbage and therefore won’t compile. (continue reading…)

Slackware 14 getting closer

by on Jul.01, 2012, under Software

So I still run Slackware Linux on pretty much all of my machines, which I often smile upon when I see another Ubuntu/Debian/Pokemon update break stuff (that I then get to fix, details). However, running bleeding edge Slackware-current also draws some blood every now and then. (continue reading…)

Why I hate windows

by on Jun.14, 2012, under Software

Today at work our windows 2008 server is trying to be funny.
First it had updates so it required a reboot. After that reboot it didn’t come back, so my not so computer literate colleague rebooted the windows machine, but unfortunately he also rebooted the (linux) fileserver.
Oh well.

Now for some reason WSUS doesn’t work anymore.
When trying to start the WSUS management console it simply crashes with no explanation whatsoever:

WSUS Management Console crashes

WSUS Management Console crashes when started. Great.

So, I figured, let’s check the logs. Ahaha. So, after browsing through the eventviewer for about half an hour and reading tons of fascinating (but useless) descriptions of successful security things, application notices and other garbage I finally ran into the corresponding event.
Here goes:

De WSUS-beheerconsole heeft een onverwachte fout aangetroffen. Deze fout kan van tijdelijke aard zijn; probeer de fout te verhelpen door de beheerconsole opnieuw te starten. If Als het probleem blijft bestaan:

Probeer de ingestelde voorkeuren voor console te verwijderen door het bestand wsus onder %appdata%\Microsoft\MMC\ te verwijderen.

Microsoft.UpdateServices.Administration.WsusInvalidServerException — Er is een uitzondering opgetreden van het type Microsoft.UpdateServices.Administration.WsusInvalidServerException.


Stack Trace:
bij Microsoft.UpdateServices.Administration.AdminProxy.GetUpdateServer()
bij Microsoft.UpdateServices.UI.AdminApiAccess.AdminApiTools.GetUpdateServer()
bij Microsoft.UpdateServices.UI.SnapIn.Wizards.OOBE.OOBEWizard.get_AdminApiTools()
bij Microsoft.UpdateServices.UI.SnapIn.Wizards.OOBE.OOBEWizard.get_ServerState()
bij Microsoft.UpdateServices.UI.SnapIn.Wizards.OOBE.OOBEWizard.SetNavigationItemEnabledStates()
bij Microsoft.UpdateServices.UI.SnapIn.Wizards.OOBE.OOBEWizard.OOBEWizardInitialize()

Suggestions 1 (restarting the console) and 2 (removing some file) obviously didn’t do shit.
Yeah, they reproduced the image above 😉
Suggestion 3 … oh wait, there is no suggestion 3. Fsck.

Just for the heck of it I clicked “Help Online”. What follows is a dailyWTF if you ask me, here’s the screenshot (click it to be able to read the details):

Windows "Help Online"

“Help Online”

Apparently when you click ‘Online Help’ they write a Visual Basic Script file to start a shell which launches a url FROM A FILE … and it fails (color me surprised).
Wonder who came up with this shit.
Oh yeah, the error message the script comes with basically says “Unspecified error”, or literally “Not further described error”.

Anyhow, I still have the WSUS issue. After trying to figure out how the heck IIS is supposed to function with WSUS (I thought the logs might give some insight, silly me) I gave up on that and decided to go with the solid “If it doesn’t work, just reinstall!” approach that normally fixes about every windows problem.

Here goes the uninstaller:

WSUS uninstaller

WSUS uninstaller

For those who don’t speak dutch, it says “Setup is not complete. Microsoft WSUS SP2 has not been removed because an error has occurred. Click Finish if you want to close the wizard.

Mind you, this problem didn’t exist last week. WSUS worked fine, computers received updates, everything was fine. My guess is that this morning’s updates included some .NET update that broke it.
However, due to the lack of useful error messages this is impossible to debug for now.
Thanks Micro~2, another swell piece of garbage you have there.

Check_MK diskstats on Xen virtual hosts

by on Jun.14, 2012, under Software

Hej look! A new WordPress release…. 3.4…. and it automagically updates, nice going guys 🙂
What’s new? A bunch of stuff I don’t care about, a few more rounded corners … meh.
And apparently they’re green. Oh well. I can be green too, see? 😉

Back to stuff I do care about: Check MK released a new major version a few days ago – it’s now on version 1.2p1.
Among the new stuff some shiny interface updates (you know, rounded corners and the like), a ton of fixes and new agents/checks (postgresql is among them), a Logwatch Pattern Analyzer and tons more.

Libgphoto retarded limits

Today Digikam didn’t quite want to do what I wanted. Yesterday I made a bunch of new photos and all I wanted was to transfer the new photos to my disk. (continue reading…)

Windows Firewall blocking applications

by on Mar.10, 2012, under Software

These days windows has a built-in firewall that’s good enough for most people. However, other than nagging you about “OH NOES YOU’RE ON A NEW NETWORK!!! ALERT!!! ALERT!!!” you need to go through quite a hassle to manually say “Don’t allow this program to make outbound connections“, something that I often want. (for example when running pirated^Wnetwork tests). (continue reading…)

World of Warcraft patch 4.3.3 and wine64

by on Mar.04, 2012, under Software

Seems like they released a new patch for World of Warcraft, increasing the version to 4.3.3 build 15354.
Obviously this broke on my wine64 installation of the game:
* Start wine64 Wow-64.exe
* Login
* “Patch required” -> OK
* “Downloading Update” -> OK

Patch 4.3.3 under wine64

Windows 7 hiberfil.sys

by on Feb.25, 2012, under Software

My windows partition was low on free disk space so I looked around for what game to remove.
Until I noticed C:\hiberfil.sys taking a whopping 12 GIGABYTES of disk space.
For a feature that I never use. (I either play games on windows or don’t run it at all, sleep mode etc was already disabled).
Seems like turning off the hiberfil.sys takes more effort than in XP (where it was a checkbox hidden in the power management options).

To disable it:
1. Start a command prompt as administrator
2. powercfg -H off

Voila, diskspace.

Slackware64 and Digikam

by on Feb.22, 2012, under Software

Last week we bought a new toy — a Canon EOS 600D (including a lens with about the same pricetag). So far I’m happy with it, it’s nice to play with a ‘real’ camera for a change. (our previous one is a simple Samsung TL205. Apples and oranges.) (continue reading…)
