Noob compiling tip - "make -j" is your friend

In today's super duper processor world if you are still only running the standard trio:

./configure 
make
make install

.. then you're really missing out. Well, that is unless you like having more time to drink your coffee while waiting for compilation jobs to finish.

Cataloging Spatial Assets - A Metadata Script Approach

Years ago I started writing some scripts with the end goal of doing a wholesale migration of my data into open source spatial databases. I since left that job and didn't have much need for the scripts, but recently picked them back up again. I never made it to the migration part, but decided instead to focus on cataloging my GIS data so I could then create other apps to use the catalog for looking things up, creating overview maps, and ultimately to fuel migration scripts.

When copy with force doesn't work in Linux bash...

Hidden feature alert! I guess I have been a good boy and use sudo more than I do log in as root, or I would have discovered this much earlier on. While updating some website software with a new version, I wanted to recursively copy files from a new tar ball into the old web site vhost location - while also forcing it to overwrite existing files.

Naturally, I used the cp command, but hit some interesting glitch...

Ingres db access in QGIS via GDAL/OGR VRT

My title was already long enough, but I should have added the subtitle "...on Windows". Up until this week you had to be a Windows compiling guru and a GDAL/OGR master to get the driver for Ingres to build. With a wave of his hand, Frank fixed that this week and now I (a mere Windows padowan) was able to get it running. Here are a few of the things that transpired and some examples of the end result. Things are easier on Linux (what's new?), but I needed to crack the Windows nut for a few reasons since it wasn't quite as ready.

Onto Actian, Ingres db and a New Book

A few people were wondering what I've been up to since I stopped working for OSGeo back in November. There are two big things going on that I'm excited about.

High resolution screenshots (SOLVED!)

Ever want to take a screenshot at higher-than-your-monitor supports resolutions? I do! I laser print quality, e.g. 300-600 DPI (dots per inch) not a measly 70-90DPI like my screen supports. So if aiming for a 10" wide print out, I'd need a 3000 pixel wide image. I don't know about you but my monitor hasn't gotten up to 2000 yet :)

I found (at least) two particular approaches that I am using now to help with this task...

An OSGeo Marketplace?

I've mentioned before about the OSGeo Service Providers Directory. It's nothing fancy but quite useful, especially if you're trying to get a feel for the ecosystem of providers out there. Currently there are 196 providers registered (are you?) for 25 software projects. I haven't done the country or language calculations, but I took a look at the cumulative number of service providers saying they support a given GFOSS project.
