comment GDAL virtual file system, how to create your own
It depends on what you are asking for and the driver. gdalinfo /vsicurl/... will download what the driver needs to display the info. If you pass -stats, it would have to donwload the image data.

You can probably use the /vsicurl/ handler. If not, it would be a perfect example for you.

comment GDAL virtual file system, how to create your own
There are VSI implementations that can use memory buffers and 'subfiles' (files within files). See: gdal.org/cpl__vsi_8h.html#af9c1b931449d423e7a80bacb75ff0717 and gdal.org/cpl__vsi_8h.html#abaee4232440e012b4b9920934fc571cc

comment Python Band.SetNoDataValue(), sets all bands at once
GeoTiffs only support one no data value for all bands. The GDALData model suggests support for band specific no data, but some (probably many) formats and dataset specific. There is a ticket open in trac: trac.osgeo.org/gdal/ticket/2083

comment different data range of raster file in mapserver and qgis
Probably not. GDAL typically operates on images and pixel values. Scale and offsets are typically associated with displaying pixel data. A quick search turned up a github pull request with no doc changes that I can see, although I don't know how QGIS does such things: github.com/qgis/QGIS/pull/1066

QGIS and IDV are applying the offset and scale values, gdalinfo gives raw pixel values.

comment Raster created by python GDAL interpreted upside down
The affine geotransform uses the upper left corner as the origin, this is typically minx, maxy. See: gdal.org/gdal_datamodel.html

comment Add band to GDAL VRT dataset and convert to TIFF
Use a different filename for the final tiff, the vrt needs the original, when you overwrite it, the vrt can't find it.

comment Use GDAL command line to copy projections
Ah. You can use gdal_edit.py to edit corners and srs. It just overwrites data: gdal.org/gdal_edit.html

comment gdalwarp won't export AAIGrid
It's not gdalwarp, it's the driver for AAIGrid. It's ascii and is written sequentially, so you can't update existing datasets, only copy them.

comment Rasterizing polyline data with QGIS/GDAL: custom line width
You could potentially use a buffered geometry to get your results, although that is not a certain solution.

comment gdalwarp increase resolution
COMPRESS and gdalwarp may not always work, see: trac.osgeo.org/gdal/wiki/UserDocs/GdalWarp although I'm not sure this applies to your version. You can also use -wo NUM_THREADS=ALL_CPUS or -wo NUM_THREADS=N to (possibly) speed things up.
