  • Find largest value of integer in repeating string

    - by dotancohen
    I have a script log file that looks a bit like this: 2012-9-16 Did something Did 345 things Script time: 244 seconds 2012-9-17 Did yet something Did another thing 23 times Script time: 352 seconds 2012-9-18 Did something special for 34 seconds 51 times Did nothing at all Script time: 122 seconds I would like to find the largest value of N in the lines Script time: N seconds. However, I need to keep the context, so simply removing all lines that don't contain Script time in them is not a viable solution. Currently, I am grepping for lines with Script time, then sorting those to find the highest value, then going back to the original file and searching for that value. However, if there is a more straightforward way then I would love to know. This is on Vim 7.3 on a recent CentOS. I would prefer to remain in VIM if possible. Thanks.

  • copying program arguments to a whitespace separated std::string

    - by PaulH
    I have a Visual Studio 2008 C++ application where I would like to copy all of program arguments in to a string separated by a whitespace " ". i.e., if my program is called as foo.exe \Program Files, then my folder string below would contain \Program Files Below is an example of what I'm doing now. I was wondering if there was a shorter or easier method of doing this. Is there an easy way to eliminate the std::wstringstream variable? int _tmain( int argc, _TCHAR* argv[] ) { std::wstringstream f; std::copy( argv + 1, argv + argc, std::ostream_iterator< std::wstring, wchar_t >( f, L" " ) ); std::wstring folder = f.str(); // ensure the folder begins with a backslash if( folder[ 0 ] != L'\\' ) folder.insert( 0, 1, L'\\' ); // remove the trailing " " character from the end added by the std::copy() above if( *folder.rbegin() == L' ') folder.erase( folder.size() - 1 ); // ... } Thanks, PaulH

  • nginx rule to capture header and append value as query string

    - by John Schulze
    I have an interesting problem I need to solve in nginx: one of the sites I'm building receives inbound traffic on port 80 (and only port 80) which may have a certain header set in the request. If this header is present I need to capture the value of it and append that as a querystring parameter before doing a temporary redirect (rewrite) to a different (secure) server, while passing the paramater and any other querystring params along. This should be very doable, but how!? Many thanks, JS

  • Database schemas WAY out of sync - need to get up to date without losing data

    - by Zind
    The problem: we have one application that has a portion which is used by a very small subset of the total users, and that part of the application is running off of a separate database as well. In a perfect world, the schemas of the two databases would be synced up, but such is not the case. Some migrations have been run on the smaller database, most haven't; and furthermore, there is nothing such as revision number to be able to easily identify which have and which haven't. We would like to solve this quandary for future projects. During a discussion we've come up with the following possible plan of action, and I am wondering if anyone knows of any project which has already solved this problem: What we would like to do is create an empty database from the schema of the large fully-migrated database, and then move all of the data from the smaller non-migrated database into that empty one. If it makes things easier, it can probably be assumed for the sake of this problem specifically that no migrations have ever removed anything, only added. Else, if there are other known solutions, I'd like to hear them as well.

    - by ungalnanban
    I have a log file which has first few characters of every line as a timestamp. 2010-06-01 04:56:02,802 DEBUG {Thread-27} Some text message 2010-06-01 04:56:02,802 DEBUG {Thread-27} Some text message 2010-06-01 04:56:02,802 DEBUG {Thread-27} Some text message 2010-06-01 04:56:02,802 DEBUG {Thread-27} Some text message 2010-06-01 05:22:02,802 DEBUG {Thread-27} Some text message 2010-06-01 05:22:02,802 DEBUG {Thread-27} Some text message 2010-06-01 05:22:02,802 DEBUG {Thread-27} Some text message 2010-06-01 05:22:02,802 DEBUG {Thread-27} Some text message 2010-06-01 06:43:02,802 INFO {Thread-27} Some text message 2010-06-01 06:43:02,803 INFO {Thread-27} Some text message 2010-06-01 06:43:02,804 INFO {Thread-27} Some text message 2010-06-01 06:43:02,804 INFO {Thread-27} Some text message 2010-06-01 06:43:02,809 DEBUG {Thread-27} Some text message 2010-06-01 06:43:02,809 DEBUG {Thread-27} Some text message 2010-06-01 06:43:02,809 DEBUG {Thread-27} Some text message 2010-06-01 07:08:02,809 DEBUG {Thread-27} Some text message 2010-06-01 07:08:02,809 DEBUG {Thread-27} Some text message My aim to find all such lines which have the timestamp of 1 hr before the current time.

    - by sfactor
    i am trying to get some data from the user and send it to another function in gcc. the code is something like this. printf("Enter your Name: "); if(!(fgets(Name, sizeof Name, stdin) != NULL)) { fprintf(stderr, "Error reading Name.\n"); exit(1); } However, i find that it has an \n character in the end. so if i enter John it ends up sending John\n. so how do i remove that \n and send a proper string.

  • How to generate a random alpha-numeric string in Java

    - by Todd
    I've been looking for a simple java algorithm to generate a pseudo-random alpha-numeric string. In my situation it would be used as a unique session/key identifier that would "likely" be unique over 500K+ generation (my needs don't really require anything much more sophisticated) . Ideally I would be able to specify a length depending on my uniqueness needs. For example, a generated string of length 12 might look something like "AEYGF7K0DM1X". Answers: I like @Apocalisp and @erickson's answers equally well. The only downside to @Apocalisp's answer is it requires an apache class. Thanks to both for the help!

  • Construct a LPCWSTR on WinCE in C++ (Zune/ZDK)

    - by James Cadd
    What's a good way to construct an LPCWSTR on WinCE 6? I'd like to find something similar to String.Format() in C#. My attempt is: OSVERSIONINFO vi; memset (&vi, 0, sizeof vi); vi.dwOSVersionInfoSize = sizeof vi; GetVersionEx (&vi); char buffer[50]; int n = sprintf(buffer, "The OS version is: %d.%d", vi.dwMajorVersion, vi.dwMinorVersion); ZDKSystem_ShowMessageBox(buffer, MESSAGEBOX_TYPE_OK); That ZDKSystem_ShowMessageBox refers to the ZDK for hacked Zunes available at: http://zunedevwiki.org This line of code works well with the message box call: ZDKSystem_ShowMessageBox(L"Hello Zune", MESSAGEBOX_TYPE_OK); My basic goal is to look at the exact version of WinCE running on a Zune HD to see which features are available (i.e. is it R2 or earlier?). Also I haven't seen any tags for the ZDK so please edit if something is more fitting!

  • Android - Loop Through strings.xml file

    - by Alexis Cartier
    I was wondering if there is anyway to loop through the strings.xml file. Let's say that I have the following format: <!-- FIRST SECTION --> <string name="change_password">Change Password</string> <string name="change_server">Change URL</string> <string name="default_password">password</string> <string name="default_server">http://xxx:8080</string> <string name="default_username">testPhoneAccount</string> <!-- SECOND SECTION --> <string name="debug_settings_category">Debug Settings</string> <string name="reload_data_every_startup_pref">reload_data_every_startup</string> <string name="reload_data_on_first_startup_pref">reload_data_on_first_startup</string> Now let's say I have this: private HashMap<String,Integer> hashmapStringValues = new HashMap<String, Integer>(); Is there a way to iterate only in the second section of my xml file? Maybe wrap the section with a tag like <section2> and then iterate through it? public void initHashMap(){ for (int i=0;i< ???? ;i++) //Here I need to loop only in the second section of my xml file { String nameOfTag = ? // Here I get the name of the tag int value = R.string.nameOfTag // Here I get the associated value of the tag this.hashmapStringValues.put(nameOfTag,value); } }

  • DB4o Linq query - How to check for null strings

    - by Dave
    Hey there - simple query: var q = (from SomeObject o in container where o.SomeInt > 8 && o.SomeString != null //Null Ref here select o; I always get a null reference exception. If I use String.IsNullOrEmpty(o.SomeString) the query takes about 100 times as long, as if I use && o.SomeString != "" (which is way faster, but obviously not correct). I'm guessing because DB4o needs to activate the objects, in order to pass them in to the IsNullOrEmpty call, and can't use the indexes. My question is, what's a better way to check for nulls in this situation? Is there something like: mystring != Db4o.DBNull.Value, or something? Cheers, Dave

  • Separating null byte separated UNICODE C string.

    - by Ramblingwood
    First off, this is NOT a duplicate of: http://stackoverflow.com/questions/1911053/turn-a-c-string-with-null-bytes-into-a-char-array , because the given answer doesn't work when the char *'s are Unicode. I think the problem is that because I am trying to use Unicode and thus wchar_t instead of char, the length of each character is different and thus, this doesn't work (it does in non-unicode): char *Buffer; // your null-separated strings char *Current; // Pointer to the current string // [...] for (Current = Buffer; *Current; Current += strlen(Current) + 1) printf("GetOpenFileName returned: %s\n", Current); Does anyone have a similar solution that works on Unicode strings? I have been banging my head on the this for over 4 hours now. C doesn't agree with me.

  • PHP preg_replace() pattern, string sanitization.

    I have a regex email pattern and would like to strip all but pattern-matched characters from the string, in a short I want to sanitize string... I'm not a regex guru, so what I'm missing in regex? <?php $pattern = "/^([\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+\.)*[\w\!\#$\%\&\'\*\+\-\/\=\?\^\`{\|\}\~]+@((((([a-z0-9]{1}[a-z0-9\-]{0,62}[a-z0-9]{1})|[a-z])\.)+[a-z]{2,6})|(\d{1,3}\.){3}\d{1,3}(\:\d{1,5})?)$/i"; $email = 'contact<>@domain.com'; // wrong email $sanitized_email = preg_replace($pattern, NULL, $email); echo $sanitized_email; // Should be [email protected] ?> Pattern taken from: http://fightingforalostcause.net/misc/2006/compare-email-regex.php (the very first one...)

  • Remove all problematic characters in an intelligent way in C#

    - by J. Pablo Fernández
    Is there any .Net library to remove all problematic characters of a string and only leave alphanumeric, hyphen and underscore (or similar subset) in an intelligent way? This is for using in URLs, file names, etc. I'm looking for something similar to stringex which can do the following: A simple prelude "simple English".to_url = "simple-english" "it's nothing at all".to_url = "its-nothing-at-all" "rock & roll".to_url = "rock-and-roll" Let's show off "$12 worth of Ruby power".to_url = "12-dollars-worth-of-ruby-power" "10% off if you act now".to_url = "10-percent-off-if-you-act-now" You don't even wanna trust Iconv for this next part "kick it en Français".to_url = "kick-it-en-francais" "rock it Español style".to_url = "rock-it-espanol-style" "tell your readers ??".to_url = "tell-your-readers-ni-hao"

  • SQL Server Command Timeouts Timeout expired. The timeout period elapsed prior to completion of the o

    - by user104295
    Hi there, we've had a ASP.NET web application deployed for a number of years now.... last week we migrated to a slightly slower server to save some money. Now we're frequently getting command timeouts: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding This is understandable in that a slower server will take longer to produce results; take longer time and produce a timeout. Is there any system-wide way to get SqlClient to set a longer timeout? We cannot change the code, as it's everywhere... we're using multiple data access technologies as well. Maybe there's a default command timeout setting on a connection string? We just need to increase it by 30 seconds; we're happy to wait a bit longer for queries to return. thanks

  • xquery expression to return a link text only if it contains within it a specific string

    - by Arvind
    I want to extract some links from a XML document (links are in same format as on html pages). Now for eg a link is "http://xyz.com/start/tyu/a.html" and another is "http://ert.com/tyu/b.html" while a third link is "http://asdf.com/ghjk/c.html" From the above 3 links (which I have with me using a for clause in a FLWOR expression)...I want only the links which contain within them a string "tyu" to be selected-- I thought of using substring for this, but substring requires start and end positions to be specified- whereas in my scenario, I dont know at which position the desired string will be. How do I do substring matching in such a scenario, i.e. where exact position for occurrence of substring, is not known? I can use XQuery 1.0 for this purpose. Finally, I want to extract the link URL, as well as link text...
