Where is my free space, windows, where is my free space?

I had a strong wish to install Autodesk Revit 2013 just a days ago. Besides it needs 38 GB of free space, it did not fit on my clogged 100 GB system drive.
Too bad. Ok, my drive is oldish 160 GB Seagate, but still, windows7 seems like a disc hog.

So i’ve decide to investigate the case. Using RidNac, i made a small tour to the HDD space. Read the rest of this entry »

Using Revit Server 2012 by non-domain members

The last issue in the Migration Hell was Revit Server. To be precise, not the application itself, but the client authentification.
With all it’s bells-n-whistles, it lacks most part of the documentation. The application itself runs on IIS, uses Windows (NTLM) or Basic authentification, but nothing is said about the Revit client. The only thing you can find – you must login as domain member to use the Revit Server.

It’s not true. You should, but must not.

Two things must be done on the client to use Revit Server:

  1. authenticate in the domain and every server you will need to use. You must use your domain login credentials to authentificate. The AD domain uses trust relations to authentificate you in the domain servers. If you prefer not to login to AD domain, you must take care of it by yourself
  2. change environment variables.
    • %USERDOMAIN% point to the current domain, if logged as domain member. If not, it’s pointing to the computer name. Setting the variable to the domain name needed (eg. SET USERDOMAIN=MYCOMPANY) will do the job. You should not use DNS domain name, eg. MyCompany.COM, it’s set in %USERDNSDOMAIN% and is useless in the case of Revit Server
    • %USERNAME% must be set to your AD’s username, without AD prefix or FQDN suffix. Eg. if your AD domain login is mycompany.com\PerfectUser or PerfectUser@Mycompany.COM, use “SET USERNAME=PerfectUser”.

That’s all. Enjoy.

PS: if you use Local Revit Server, and Central Server is located somewere in the Other Domain, you will probably need to authentificate to the Central Revit Server too. Not sure about this.

pull

is the only missing keyword, OpenVPN client-to-server config need to work correctly on the client.
It took me 3 days to figure this out, a lot of RTFM’ing and head-banging.

Full client config looks this way:

Get rid of removed packages in Debian

Every time package is removed via `apt-get remove`, a tiny piece of its configuration can be kept in your system. If you ever need to reinstall the package, this information can be re-used. These packages has status ‘rc’ in the output of `dpkg -l`. But if you want to keep your system tidy and clean, you may want them to be removed.

The miraculous command is

dpkg -l | egrep ^r | cut -d ‘ ‘ -f 3 | xargs apt-get remove –purge -y

Running VirtualBox guests from physical drive

Dual boot is perfect solution in most cases.

On the other hand, if you need to peep into the other system’s files, you need to re-boot. Or use sometimes not so stable filesystem utilities.
Running fully virtualized OS, using eg Xen as supervisor, creates additional load an hardware, maybe not too big when running multiple OS’es on the pretty new server, but significant, if it is a laptop. And yes, you NEED to keep data in-sync between virtual and real OS. Read the rest of this entry »

Migration hell: moving printers in Windows

Our campus, Faculty of Architecture, VGTU is moving to the totally new subnet. As we use DHCP for IP distribution, no real problems except `sed` are going to appear.
The pleasing moment is we are getting a fresh IP range.
The headache is TCP/IP printers.

WPKG has good printer addition/ installation guide in http://wpkg.org/Printer_configuration , but it does not cover changing IP port numbers.
As a CEO on all computer infrastructure, I need to find any solution to make the movement smoothly.

I was unable to find a ready-made solution, and in-house tool appeared after several hours in the Net.
I need to apologize for bugs and errors, as it is the first (and hopefully the last) VB script. It uses WMI. Testing box was W7, x64.
Maybe someone will find it useful.

Localised fonts

The very first try on “Flux-the-Architect“. Added Ą,Č,Ę,Ė,Į,Š,Ų,Ū,Ž glyphs and some minor symbols (°, ±, ², ³). The font is OpenType in TrueType encoding. OpenType fonts in PS encoding does not work in AutoCAD.

Troubles in Virtual World

For testing OpenOffice.org i’ve set up a VirtualBox, running Debian/testing in x86and amd64 architectures.
In some cases, mouse integration does not work correctly. Although mouse works perfectly in the Guest window, it’s impossible to move it out without pressing Host key (left Ctrl in MS Windows).
VirtualBox guest additions are installed, guest resizing and shared folders works perfectly.
The solution was found in VirtualBox forums :
/etc/X11/xorg.conf must contain

Section “InputDevice”
Identifier “Configured Mouse”
Driver “vboxmouse”
Option “CorePointer”
EndSection

note two lines: vboxmouse tells X.org to use mouse driver from VirtualBox guest additions, and CorePointer instructs to use this pointer as primary. Without CorePointer line the vboxmouse driver is used, but it’s still impossible to move it outside guest’s window.

How to start multisite Gallery2 on Debian

I had a little disc and database crash, so the site was not updated recently.

Well, WordPress was updated easily, but i had problems with Gallery2.

I need a multisite deployment of Gallery2. Although it is supported from the installer, some important steps are missing.

In order multisite Gallery2 to work, you will need to add some symlinks to every deployment of the Gallery2:
