Mini trick: Don't show printers in samba shares

Posted by coldtobi | 19 May, 2009, 22:24

To help Windows understanding, that your local samba server does not support a printer, add to your smb.conf in the [global] section

    disable spoolss = yes

Reload samba, add it will vanish ;-)

php based home inventory system

Posted by coldtobi | 19 Apr, 2009, 21:07

I'm currently looking for a system for keeping an overview over my electronic parts I have "on stock", storing the datasheets and keeping and especially where I put them.

During this I found "home-inventory". Looks ok, but also lacks some features, like it can only store images...

PS: I have to rethink about the "looks ok". The first peek on the source code reveals, that the author did not care about sanitizing user input:

                // delete first picture if exist
                $sSql = 'SELECT ITM_Picture FROM Item WHERE ITM_ID = ' . $_REQUEST['id'];
                $pictName = fetchFromDb($sSql, true);

RapRep -- Self replicating machine

Posted by coldtobi | 22 Feb, 2009, 13:17

A friend pointed me to an interesting (hardware) project: RepRap.

To quote the website:

A universal constructor is a machine that can replicate itself and - in addition - make other industrial products. Such a machine would have a number of interesting characteristics, such as being subject to Darwinian evolution, increasing in number exponentially, and being extremely low-cost.

A rapid prototyper is a machine that can manufacture objects directly (usually, though not necessarily, in plastic) under the control of a computer.

The RepRap project is working towards creating a universal constructor by using rapid prototyping, and then giving the results away free under the GNU General Public Licence to allow other investigators to work on the same idea. We are trying to prove the hypothesis: Rapid prototyping and direct writing technologies are sufficiently versatile to allow them to be used to make a von Neumann Universal Constructor.

All good projects have a slogan, and the best have a slogan that reeks of hubris. RepRap is no exception. Our slogan is:

"Wealth without money..."

Seamless integration Google Search into Lifetype (Part 1)

Posted by coldtobi | 16 Jul, 2008, 17:43 Some weeks ago, I integrated the Google Search into the blogging platform on this site. At this time I already planned to do a "how to", as this might be also interesting for others. Seamless integration means, that the search results are embedded in the look and feel of the blog: It should use the same templates and also present the search results matching to the design of the blog.

Of course, you don't want to maintain different template system, so best the search engine will use exactly the same template files also used for the rest of the blog.

How to check if you have ModRewrite

Posted by coldtobi | 12 Jul, 2008, 18:58

ModRewrite comes handy for SEO and other opportunites, where you want to change URL to something else. Lifetype uses this to assemble all the php parameters and make more search-engine and humanfriendly URLs. Also, you can do the RFI Protection I described earlier.
To find out, whether your webhoster's Apache supports ModRewrite, you have basically two options:
