Like my original image is of dimensions (610 by 406) but on being read using opencv::imread function, its dimensions are 406 by 610. Also, if I rotate my original image before passing it to the function then also, no change. The image read still has original dimensions.\n\nPlease see example code and images for clarification:\nSo, below I have provided the input images: one is original and second one is rotated (I rotated it using windows rotate command, by right-clicking and selecting 'rotate right'). Output I get for both the images is same. It seems to me that rotating image did not actually change its shape. I think so because, when I try to put the rotated image here then also, it was showing the un-rotated version of it only (in the preview) so, I had to take a screen-capture of it and then, paste it here.\n\nThis is the code:\n\nimport cv2\nimport numpy as np\nimport sys\nimport os\n\nimage = cv2.imread(\"C:/img_8075.jpg\")\nprint \"image shape: \",image.shape\ncv2.imshow(\"image\",image)\ncv2.waitKey(0)\nimage2 = cv2.imread(\"C:/img_8075_Rotated.jpg\")\nprint \"image shape: \",image2.shape\ncv2.imshow(\"image\",image2)\ncv2.waitKey(0)\n\n\nThe result I get for this is: image shape: (406,610,3)\n image shape: (406,610,3)\nfor both the images.\n\nI am unable to paste input/output pictures here since, it says you should have '10 reputations' and I have just joined.\nAny suggestions would be helpful. thanks!" ]

The problem is, I'm not sure how to keep the listener alive indefinitely (just want it sitting there in a loop only taking action when it receives a packet).\n\nCurrently, I'm able to use the go-fastping library and can send and receive packets if it's a two way communication (I send it, they respond, I process the remote response). The question is how do I make this asymmetrical?\n\nMy attempt at a listener was:\n\nfor {\n conn, err := icmp.ListenPacket(\"ip4:icmp\", \"192.168.1.8\")\n if err != nil {\n fmt.Println(err)\n }\n}\n\n\nbut this doesn't work. My logic here was that I want a while true loop to keep the listener alive (in this case that's the for {), then I listen for new packets with ICMP's ListenPacket but I don't seem to be getting anything using this approach. \n\nAny ideas or help would be greatly appreciated.

I have researched this and I've added the remote heroku repo using this:\n\ngit remote add heroku-remote [email protected]:project.git\n\n\nOf course to modify it for my code would be like this:\n\ngit remote add heroku-remote [email protected]:morning-stream-6357.git\n\n\nBut I'm still not able to push from the command line, I've been pushing using the heroku deploy button that lets me deploy the master branch but I think that's not a good idea otherwise I think it would be mentioned in the book. Any help at all would be greatly appreciated. \n\nEDIT: In case anyone is wondering,I did install the heroku tool belt.\n\nEDIT: I should have noted before that I have indeed already tried running this command:\n\ngit push heroku master\n\n\nBut it still gives me an error:\n\njose@jose-desktop:~/Workspace/sample_app$ git push heroku master\nTo [email protected]:morning-stream-6357.git\n !

Integrate the remote changes (e.g.\nhint: 'git pull ...') before pushing again.\nhint: See the 'Note about fast-forwards' in 'git push --help' for details.\n\n\nI'm not sure what's causing this, it should be up to date.

[ "Doesn't PIC mean no relocations?", "I'm building an ELF SO for bada on ARM using GCC. The compiler options include -fpic. Yet in the built file, when I do readelf -r, there's a whole lot of relocation records, of following types:\n\n\nR_ARM_RELATIVE\nR_ARM_REL32\nR_ARM_ABS32\nR_ARM_GLOB_DAT\nR_ARM_JUMP_SLOT\n\n\nWhat am I misunderstanding here?\n\nEDIT: from what I can see, the PIC implementation in the compiler doesn't use GOT. Instead, they use PC-relative addressing with stored constants being offsets from point of use to the symbol address; that's resolved by the linker. Like this, to read a global variable:\n\n ldr r12, OffsetToVar\nPointOfUse:\n ldr r0, [r12, pc] \n# r0 now has the value of MyVar\n\n#...\n\n# At function's end...\nOffsetToVar:\n .long MyVar-PointOfUse-8\n# Compiler can't resolve this, since it doesn't know\n# the address of MyVar, but linker can\n\n\nSimilar idea for cross-module function calls. When a project mixes ARM and Thumb code though, the latter may misfire. But I've worked around that." ]
