• Bash script to replace spaces in file names

  - by armandino

  Can anyone recommend a safe solution to recursively replace spaces with underscores in file and directory names starting from a given root directory? For example, $ tree . |-- a dir | `-- file with spaces.txt `-- b dir |-- another file with spaces.txt `-- yet another file with spaces.pdf becomes $ tree . |-- a_dir | `-- file_with_spaces.txt `-- b_dir |-- another_file_with_spaces.txt `-- yet_another_file_with_spaces.pdf

• Is pdf virus proof? [closed]

  - by Jonathan

  I am creating a secure document portal for a client. One of the things that they are worried about is having someone upload a document with a virus. One solution that might work is to enforce that they only upload pdf files. My question is two fold: Most importantly, is a pdf document virus proof? How can you determine in a *nix environment that a file is a pdf, besides just looking at the extension. Thanks! Jonathan

• PHP Compare Two Arrays?

  - by Sjwdavies

  I'm trying to compare two entries in a database, so when a user makes a change, I can fetch both database entries and compare them to see what the user changed, so I would have an output similar to: User changed $fieldName from $originalValue to $newValue I've looked into this and came accross array_diff but it doesn't give me the output format I need. Before I go ahead and write a function that does this, and returns it as a nice $mtextFormatDifferenceString, can anyone point me in the direction of a solution that already does this? I don't want to re-invent the wheel..

• Visual Studio 2010 -- how to reduce its memory footprint

  - by GregC

  I have a solution with just under 100 projects in it, a mix of C++ and C# (mostly C#). When working in VS2005, the working set of Visual Studio is considerably smaller than that of VS2010. I was wondering if there are some things that can be turned off, so I can develop in VS2010 under 32-bit OS without running out of memory.

• c++ dynamic_cast error handling

  - by Nazgob

  Is there any good practice related to dynamic_cast error handling (except not using it when you don't have to)? I'm wondering how should I go about NULL and bad_cast it can throw. Should I check for both? And if I catch bad_cast or detect NULL I probably can't recover anyway... For now, I'm using assert to check if dynamic_cast returned not NULL value. Would you accept this solution on a code review?

• filtering directly and indirectly connected things from list

  - by Andreas Romeyke

  Hello, if you have a function "test a b" which returns true if a and b are connected directly and if you have a given unordered list of things, what would be an elegant and fast solution to filter all connected things from given list? Example: let test a b = let diff = a - b in diff == 0 ;; let lst = [4;1;7;3;8;9;2;0] ;; filter_connected 2 lst ;; - [4;1;3;2;0] Any hints?

• Can you reverse order a string in one line with LINQ or a LAMBDA expression

  - by Student for Life

  Not that I would want to use this practically (for many reasons) but out of strict curiousity I would like to know if there is a way to reverse order a string using LINQ and/or LAMBDA expressions in one line of code, without utilising any framework "Reverse" methods. e.g. string value = "reverse me"; string reversedValue = (....); and reversedValue will result in "em esrever" EDIT Clearly an impractical problem/solution I know this, so don't worry it's strictly a curiosity question around the LINQ/LAMBDA construct.

• How do you rotate a two dimensional array?

  - by swilliams

  Inspired by Raymond Chen's post, say you have a 4x4 two dimensional array, write a function that rotates it 90 degrees. Raymond links to a solution in pseudo code, but I'd like to see some real world stuff. [1][2][3][4] [5][6][7][8] [9][0][1][2] [3][4][5][6] Becomes: [3][9][5][1] [4][0][6][2] [5][1][7][3] [6][2][8][4] Update: Nick's answer is the most straightforward, but is there a way to do it better than n^2? What if the matrix was 10000x10000?

• Is there a way to change the color of plots in jQuery flot without redrawing the whole chart?

  - by Sam Lee

  I have a chart that I'm drawing using flot. I want to change the colors of the data plots when someone hovers over text. Currently, I am doing this by redrawing the entire chart each time I need to highlight something. This is pretty slow (about 30 milliseconds for a simple chart, as much as 100 for a more complicated chart). Since all I want to do is change the color, is there a faster solution?

• Algorithm for multiple word matching in a text, count the number of every matched word

  - by 66

  I have noticed that it has solutions for matching multiple words in a given text, such as below: http://stackoverflow.com/questions/1099985/algorithm-for-multiple-word-matching-in-text If I want to know exactly the number of appearances of each matched word in the text, my solution is like this: step 1: using ac-algorithm to obtain the maching words; step 2: count the number of each word obtained in step 1 is there a faster way? Thx~
