Ubuntu :: Software That Can Compare And Find Similar & Duplicate Images For Ubuntu?
Apr 1, 2011Here's the problem I hope to solve: I had to recover a hard drive with pictures and other data on it after the file system was erased. Now, in some cases there are 5 or more instances of the same image with different sizes and different file names. Sometimes the images are also in different formats such as jpeg or pnm...
Some of these images may be duplicates of images in a backup hard drive. I am just asking to see if there is a software that can visually compare images, find visual similarities, and ask me which to keep.
Software :: Download Some Images From A Website - Single Column Of Links To The Images?
Jul 26, 2010I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.

May 2, 2011I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.
General :: Replace DVD / CD Install Images With USB Images
Sep 21, 2009I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.

View 1 Replies View RelatedProgramming :: MD5 Algorithm Implementation
Apr 27, 2011I have a copy of the MD5 algorithm and I'm taking a look at the source. It's pretty interesting but there are a few things that I'm curious about and I was wondering if anyone a bit more intuitive than I could help me out.The function declarations in the MD5 files are a bit unfamiliar to me. There is a macro used called PROTO_LIST, which I'm still not sure as to what this thing is doing exactly, but it's littered everywhere throughout the source.The signature here isn't too unfamiliar to me with the exception of the position of the PROTO_LIST macro. So here is a function with an unnamed argument of type MD5_CTX*.To me, this resembles an initializer list found in C++ with constructors but I certainly don't think that is the case here. So my questions about this are (1) how is this legal code in C and (2) what functionality has the PROTO_LIST macro provided for the function?

Jan 3, 2011there are 3 nodes..A,B and C. Node A wants to send information to Node B but it does so by sending it to Node C first which then sends to B. And similarly Node B sends to A. In this simultaneously C doesn't send to both A and B. This is the in built algorithm..but i want to change it to: A and B send their packets to C and C sends both these packets to A and B..by ORing... In the receiver side...node A can receive the wanted packet and also B. Where do i change the algorithm?

Programming :: Which Is Scheduling Algorithm Which Will Make Thread O?
May 4, 2011I have a timer thread, and when it expires, it sets a flag. The only problem is, if any higher priority thread comes in between, then the timer is not expired in real time.Thus i want to set a highest priority to my thread. Now, i know 2 algos, which can make my thread in real time are: SCHED_FIFO and SCHED_RR.
So, here are my queries: 1) Which scheduling algo is best suited for this purpose? 2) Is it guaranted to work in real time if i use that algo (you suggest in 1) and set the max_priority by getting the maximum settable priority for that particular algorithm using, int sched_get_priority_max(int policy);
Programming :: Algorithm For Binary Frequency Search?
Jul 16, 2010I've got a bit of an obscure question for you to test your brains a wee bit. I'm trying to implement a search program to find areas of high density in a binary string.
E.g.
Code:
[0001001010
0001110001
0000001000
1001000010
0101100100]
Where density is the number of 1's / number of digits with a maximum number of digits being the current number in a buffer (in this example 50). So for the example the density for the whole buffer is 15/50. But the density of Buffer[14..20]=[1110001]=4/7. So if looking for areas of density = 1/3 it would find the longest sequences of density over 1/3.So in the example. Buffer[4..9]=[100101]=3/6=1/2 which is above 1/3 but it is within the Buffer[4..48]=[100101000011100010000001000100100001001011001]=15/45=1/3

Programming :: Algorithm For Finding The Shortest Path Between Geocoordinates?
Jun 27, 2011AStar works on the basis of straight lines, AFAIK. In my case, we have geocoordinates and I can get the straight line distance between the waypoints. But I am wondering how approximate will the route calculated on this basis be? The actual distance "by road", which actually matters can be different.
Example. Assuming A and B are on the same plane, and will be equidistant from the goal point, if we consider a straight line between A and the goal point and, B and the goal point. The distance "by road" between A and the goal point may be greater or lesser than B. But because the AStar works on the basis of straight lines, it will return both the routes as the shortest. If yes, then which algo should be considered , if we want the results on the basis of actual distance in Km/m?

Jun 5, 2010upgrading my notebook from Slackware 13.0 to 13.1. There are always some tricky things to wrap around when such upgrade times come, but now I think I caught a bug in mkinitrd, if I'm not wrong. mkinitd doesn't return when I run:
[code]...
After some debugging, I found that the routine copy-libs() is stuck in an infinite loop, because the statement "while [ "$COUNT" != "0" ]; do" does hold always (that is, COUNT never reaches zero). This, by its side, happens because the set of libs whose dependencies should be checked against are regenerated integrally after each step, and the algorithm doesn't converge. I could fix the problem adding some code, which removes the libraries found in the iteration "i-1" from the list of files found in the iteration "i". A patch in provided below. This done, I could build my first initrd image for Slack 13.1 and put it to run with kernel 2.6.33.4.

OpenSUSE Install :: Passwd -S Output \ Ran The Command But Nothing About The Algorithm Is Returned?
Mar 23, 2010I read that passwd -S spits out informationabout a user's password including the encryption algorithm used to encrypt the password in /etc/shadow. I ran the command but nothing about the algorithm is returned. Is this a quirk in openSUSE?On another note, I've determined through other means that I've selected blowfishryption as evidenced by the $2blah$2blahblah format of the /etc/shadow entry. However, if I look at /etc/default/passwd it lists CRYPT=md5. If I'm using blowfish why would that variable be set to md5. onversely, if it is set to md5 why is the blowfish algorithm being invoked?

Programming :: Algorithm - File System Block Number For Immediate Read
May 20, 2010algorithm:breada
input: file system block number for immediate read
file system block number for asynchronous read
output:buffer containing data for immediate read {
if(first block not in cache) {
get buffer for first block
if(buffer data not valid)
initiate disk read }
if(second block not in cache) {
get buffer for second block)
if(buffer data valid) //line 1
release buffer else
initiate disk read //line 2 }
if(first block was originally in cache) //line 3 {
read first block
return buffer }
sleep (event first buffer contains valid data)
return buffer }
Here is an algorithm for block read algorithm. I have problem in
line 1: If buffer data is valid why is it releasing the buffer?
line 2: If buffer data valid why is it initiating disk read. It should have read directly from buffer?
line 3: It should be the first condition as if it is there in cache then it should return it without delay?
