  • Generic IP Camera LAN Default IP Settings DVR


    If you are converting a generic wifi IP camera to ethernet, it may not be that simple as many are default hard coded to a static IP of 192.168.1.168 and login info admin/admin. From there you can login to the camera and assign it to DHCP by going to http://192.168.1.168 For security these cameras +DVR should be on a separate untagged VLAN or if possible a physically isolated non-internet connected switch/network.

  • Cannot Print PDF Solution and Howto Resize


    If you can print other PDFs but not a particular one it is very likely that the PDF size is A4 (the longer, skinnier Asian paper size) instead of the North American letter size ( 8.5" x 11"). This breaks printing in most cases. Or it may print if you find a program that ignores the size issue. Here is an example of an A4 being rejected by a printer in Ubuntu Linux via CUPS Cannot print PDF CUPS Samsung C460: Processin........

  • Adobe Acrobat Reader for Linux to use and view XFA Fillable Forms


    The reason for not being able to read one of these dreaded/ fillable "XFA" forms is because no Linux PDF reader that I'm aware of supports them. Part of this reasoning is for security. It is really silly, they should ban these XFA forms or at least replace the Please Wait with the non-fillable version. Download Adobe Reader 9.5 for Linux from here: This is the solution but only so much, at least for me I was able to view th........

  • imagemagick convert to chop off top of image


    This is useful if you have a bunch of images/scans where the same area at the top needs to be chopped. Sometimes the -trim option (such as the case of white space on top)is wrong and ends up cropping the image and losing some text. ImageMagick's convert is very useful but tricky to find some things out as I find it to be less than intuitive sometimes. Chopping off the bottom convert -crop -0-400 image.jpg image.pdf........
