Hi! I''ve got 2 tables: products and images. Product has_many images, image belongs_to product. In images table i store product_id and name of the image (not the image itself). I''ve created a single form, where user can add any number of images for a product he/she is creating (new fields are created using javascript). The images that are uploaded are saved to public/images

I've written a piece of code (see below) to do a wavelet image decomposition, during the evaluation of this code I would like to write the results of some calculations back to the R root directory. I used assign() to do so because the names should vary when going thrue a while() loop. For some unknown reason I get an error that says: Error in assign(varname[i], imwrImage) :

I am trying to use CentOS 8 host to boot an image (OS X) that I created using dd. First I tried fdisk -l image_file.img - all looks good so I did fdisk image_file.img - this works - but seems in CentOS 8 fdisk there is no longer a toggle bootable flag option. How do I do that ? Thanks, Jerry

Good evening! I''m currently trying to submit some data and a file upload through Ajax. I''m using rails & prototype, and somewhere there''s a disconnect. I''m reasonably convinced the file upload isnt being sent at all, or if it is, Rails has absolutely no idea. The form itself heads with: <form onsubmit="new

I am new to RoR. I am trying to use file_column and rmagick to resize images uploaded to my RoR app. The problem is that only images larger than the dimensions specified in my code will resize. For instance, if the uploaded image is 98x98, then the new images will remain that size. How can I enlarge images using file_column and rmagick? Here is the code in my model: file_column

Hi, So the case is, now I''ve got a btrfs image file, which is created from a raid0 btrfs fs. And if I run ''btrfs-image -r image_file /dev/sdf'', then I have to mount it with ''degraded'' mode, and that still fails because raid0 requires two disks at least. So any ideas how to make it work? thanks, liubo -- To unsubscribe from this list: send the line

Hello, First off, many thanks for libguestfs... very useful! I'm trying to run libguestfs as an RPC service by using a python daemon with the python libguestfs bindings. With this service I'm "centrally" editing VM images, and often running many GuestFS() on the same image file in a short amount of time to edit the image's contents. The problem I'm running across is

Hey guys, So I was able to modify dlltool to produce the exact same layout as lib.exe with the same section numbers etc. I've first managed to first create the correct section so that lld gives me link errors and then resolve those errors to create an exe.
