“user3245549” is right: All of the above answers with “for loops” and nested bat files are mumbo jumbo. All you need is to just use “findstr” – example: C:\temp> findstr /S /C:”/work” * | more <– this will find the string “/work” in any file or C:\temp> findstr /S /C:”/work” “*.*” | more or C:\temp> … Read more
An addition to Jon Skeets post: The potential faster implementation is actually not hard to implement and adds only 2 lines of code, here is how I’d do it: if (midVal < key) low = mid + 1; else if (midVal > key) high = mid – 1; else if (low != mid) //Equal but … Read more
Since it is unlikely that you have to retrieve the same 500 books every day: store the data retrieved from isbndb.com in a database and fill it up book by book.
The new InnoDB full-text search feature in MySQL 5.6 helps in this case. I use the following query: SELECT MATCH(column) AGAINST(‘(word1* word2*) (“word1 word1”)’ IN BOOLEAN MODE) score, id, column FROM table having score>0 ORDER BY score DESC limit 10; where ( ) groups words into a subexpression. The first group has like word% meaning; … Read more
Read up on the Aho-Corasick algorithm and the Rabin-Karp algorithm. If the input is not too large, you don’t want to repeat the search many times and you do not have many patterns, it might be a good idea to use a single pattern algorithm several times. The Wikipedia article on search algorithms gives many … Read more
The forfiles command works without resorting to PowerShell. The article is here: Find files based on modified time Microsoft Technet documentation: forfiles For the example above: forfiles /P <dir> /S /D +12/07/2013 /P The starting path to search /S Recurse into sub-directories /D Date to search, the “+” means “greater than” or “since”
As Russel and Norvig point out in Artificial Intelligence: A Modern Approach (the most commonly used AI textbook) it is challenging to come up with a heuristic that is admissible but not consistent. Obviously, you can select values for nodes in a graph such that the heuristic they represent is admissible but not consistent. This … Read more
If you want to find all commits where the commit message contains a given word, use $ git log –grep=word If you want to find all commits where “word” was added or removed in the file contents (to be more exact: where the number of occurrences of “word” changed), i.e., search the commit contents, use … Read more

Scannned images converted to PDF which have been OCR’ed in the aftermath to make text searchable do normally contain the text parts rendered as “invisible”. So what you see on screen (or on paper when printed) is still the original image. But when you search successfully, you get the hits highlighted that are on the … Read more
