Act all suspicious.

Just did some minor testing after trying the Georeferencing toolbar in ArcGIS to create some world files (.jpgw, .pngw, .ecww, .tfw, etc.) and wanted to see how these two GIS suites treat the result. Normally I use MapWindow GIS to georeference aerial photos but its Image to Map Image Registration Plug-in is very slow and has some strange bugs that might deserve another blog post. The aerial photos were received from the provincial agency as MrSID files and were converted to ecw using IrfanView. Neither the original SID files or the ECW files had embedded projection information. In ArcGIS, I used the georeferencing toolbar and added five control points then chose Projective Transformation rather than the default Affine 1st Order Polynomial method to transform the raster. Upon clicking Update Georeferencing (Save the current warp to the dataset) from the toolbar, two files are created with the same name prefix as the .ecw file but with different extensions. They are photoname.ecw...

Though the design and compounds have been around a few years now, it was surprisingly difficult to find tires that are truly All-Weather (good for every season) per Transport Canada standards and meet or exceed the Rubber Association of Canada performance requirements. Since my tires need replacing and I'm not looking for soft winter-specific tires, I have compiled a list of tyres that have the mountain/snowflake rating based upon my search. Perhaps you'll find this list useful and that it saves you time. Nokian pioneered this class of tires and was the first to market but there are now a number of brands with a limited selection. http://www.wheels.ca/news/all-weather-tires-are-not-the-same-as-all-season-and-heres-why/ These makes include: Kumho, Toyo, Falken, Michelin, Vredestein, Hankook, Yokohama, and Nankang, Michelin, Multi-Mile, and Muteki.  Additionally, some are exclusively sold at certain retailers. Tires that have the 3PMSF icon and are all-weather cap...

Upon pressing "undo" accidentally in File Explorer on my Surface Pro 3, Windows 8.1 performs bad behaviour.  See details and frustration others have had here:  answers.microsoft.com thread It seems Windows 8.1 made all the contents of the folder disappear as a consequence of undoing a previous rename of the folder from "New Folder".  That is, the file entry in the Master File Table was lost. Hopefully the entries were deleted and the space is reusable (I'm not sure what how Windows manipulates the MFT in this case). So, I wanted to recover the files from that folder.  I first found out that Windows 8 has two kinds of "backup" systems, one called File History that is intended to make regular replicas of the tracked Libraries to a separate physical disk or to a network share.  Since this File History wasn't configured and not turned on by default on my SP3, I looked toward Volume Shadow Copy, which appears to be enabled by default on the C: drive...
