  • Quick and Dirty way to search for characters in a string

    - by mbcrump
    I saw this today on StackOverflow, all credit goes to Jon Skeet. I have always used RegEx or loops to check for special chars. This is a more human-friendly way of doing it.   Code Snippet using System;   class Program {     //field     private static readonly char[] SpecialChars = "!@#$%^&*()".ToCharArray();       static void Main(string[] args)     {         //text to search for         string text = "michael";         int indexOf = text.IndexOfAny(SpecialChars);               if (indexOf == -1)             {                 Console.WriteLine("no special char");             }               Console.ReadLine();     } }

  • build command by concatenating string in bash

    - by Lennart Rolland
    I have a bash script that builds a command-line in a string based on some parameters before executing it in one go. The parts that are concatenated to the command string are supposed to be separated by pipes to facilitate a "streaming" of data through each component. A very simplified example: #!/bin/bash part1=gzip -c part2=some_other_command cmd="cat infile" if [ ! "$part1" = "" ] then cmd+=" | $part1" fi if [ ! "$part2" = "" ] then cmd+=" | $part2" fi cmd+="> outfile" #show command. It looks ok echo $cmd #run the command. fails with pipes $cmd For some reason the pipes don't seem to work. When I run this script i get different error messages relating usually to the first part of the command (before the first pipe). So my question is whether or not it is possible to build a command in this way, and what is the best way to do it?

  • How does the build quality of laptops compare?

    - by pgwillia
    I'm looking to replace my 5 year old laptop. I want my next laptop to endure at least this long. I typically have Thunderbird, Firefox, Eclipse Java IDE, Skype, a ssh session, and Apache Tomcat running. I'm currently running Karmic Ubuntu, but am agnostic about operating system and would move to Win 7 or OS X. I frequently travel with this computer. I also value battery longevity and power conservation (if possible). Above all I'm looking to minimize cost. I think the hardware that best meets my needs is an Intel i7 processor, 8 GB RAM, 100GB @7200 rpm or SSD hardrive, and about 15 inch monitor. These specs are met by most brands. Does anyone know specific pros/cons and build quality for Macbook Pro, Lenovo Thinkpad (W510 or T510), Sony's VPC-F1190, and ASUS G Series G73JH-X1 NoteBook? Are all i7 processors created equal? Do you have other suggestion that meet my needs?

    I have a data set for employees that contains name and 3 attributes (job function, job grade and location). I then have a data set for open positions that contains the requisition number and 3 attributes (job function, job grade and job location). For every employee, i would like the three attributes associated with them compared to the same three attributes of the open positions and have the cooresponding requisition numbers displayed for each employee where there is a match.

  • How does BTRFS compare to ZFS?

    - by Zubair
    I am considering which OS and filesystem to use on some new servers I have and am considering either Free BSD with ZFS, or Linux with BTRFS. The programs I have run on both systems, so the only issue is reliability of the filesystems and performance, etc.

  • Active Directory problems while trying to perfom compare operation

    - by Alex
    I have CentOs 5.5 with Apache 2.2 and SVN installed. Also I have Windows 2003 R2 with Active Directory. I'm trying to authorize users via AD so each user have access to repo if he is a member of corespondent group in AD. Here is my apache config: LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so LDAPVerifyServerCert off ServerName svn.mydomain.com DocumentRoot /var/www/svn.mydomain.com/htdocs RewriteEngine On [Location /] AuthType basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthLDAPURL ldaps://comp1.mydomain.com:636/DC=mydomain,DC=com?sAMAccountName?sub?(objectClass=*) AuthLDAPBindDN [email protected] AuthLDAPBindPassword binduserpassword [/Location] [Location /repos/test] DAV svn SVNPath /var/svn/repos/test AuthName "SVN repository for test" Require ldap-group CN=test,CN=ProjectGroups,DC=mydomain,DC=com [/Location] When I'm using "Require valid-user" everything goes fine, "Require ldap-user" also works. But as soon as I use "Require ldap-group" authorization fails. Trere are no errors in apache logs, but Active Directory shows folowing error: Event Type: Information Event Source: NTDS LDAP Event Category: LDAP Interface Event ID: 1138 Date: 10/9/2010 Time: 1:28:52 PM User: MYDOMAIN\binduser Computer: COMP1 Description: Internal event: Function ldap_compare entered.

  • How does PhP internally represent string?

    - by Jim Thio
    UTF8? UTF16? Does the string in PhP also keep tracks the encoding used for that string? A good answer would give me a sample of Let's look at this script for example. Say I do $original = "??????????????"; What actually happen? Obviously I think $original will not contain just 7 characters. Those glyps must each be represented by several bytes there. Then I do $converted= mb_convert_encoding ($original , "UTF-8") What will happen to $converted? How will $converted be different than $original? Will it be just the exact same byte sequence with $original but with different encoding? Or what?

  • Unity: Assigning String value in inspector

    - by Marc Pilgaard
    I got an issue with Unity I can't seem to comprehend, and it is possibly very simple: I am trying to write a simple piece of code in JavaScript where a button toggles the activation of a shield, by dragging a prefab with Resources.load("ActivateShieldPreFab") and destroying it again (Haven't implemented that yet). I wish to assign this button through the inspector, so I have created a string variable which appears as intended in the inspector. Though it doesn't seem to register the inspector input, even though I changed the value through the inspector. It only provides the error: "Input Key named: is unknown" When the button name is assigned within the code, there is no issues. Code as follows: var ShieldOn = false; var stringbutton : String; function Start(){ } function Update () { if(Input.GetKey(stringbutton) && ShieldOn != true) { Instantiate(Resources.load("ActivateShieldPreFab"), Vector3 (0, 0, 0), Quaternion.identity); ShieldOn = true; } } Hope somebody can help, in advance... Thanks

  • pop up html as javascript string instead of hidden div for seo [closed]

    - by user1324762
    Possible Duplicate: How bad is it to use display: none in CSS? I have heard that using display:none or visibility:hidden css properties are not a very good idea for seo purposes. I have about 4 different pop up windows to display and each one has about 20 words inside it. I can create hidden divs. Another option is to store div html elements as javascript string. In this way pop up html elements will be generated from javascript string. This will be still faster than using ajax since the data is static. Is this method absolutely safe for SEO? P.S.: I was just asking about similar question on http://stackoverflow.com/questions/12389075/storing-data-in-javascript-array-for-further-use, but this one is different, it is about static data and about SEO.

  • Compare Error logs across service fleet, find unique errors

    - by neuroelectronic
    I'm looking for a tool where I can list the servers to check, the location of the file and it would return a list of the most common errors across those servers (say like 2 or 3 servers for report brevity) and get a report something like this Server.A Server.B Server.C -------- -------- -------- 42 error.X 39 error.X 61 error.X 21 error.Y 7 error.Y 5 error.A 17 error.B 6 error.A 4 error.Y 4 error.A 2 error.R 3 error.S 3 error.R 1 error.S 1 error.R Of course, excluding timestamps and other error details and just grepping out the common sub-strings and listing them like so. I'd be able to look at the table and see that error.B is unique to Server.A and conclude that there is something up with Server.A. Does something like this already exist? Is this something I'll have to code myself? I'm not necessarily looking for this specific report, just the functionality to find unique errors across a set of error logs.

  • Record Matching Software to Compare two tables and match on % Based

    - by Crazyd
    So I have some table with Name, Address, and Zip with no record data attached; and I have a table which has all the same, but has more information and I need a way to merge the tables when they don't match 100%. How do I match them up if they aren't Identical? I'm a newb @ SQL, but I know they won't match up for the most part and I can't be the only one with this issue. However software which will do this has proven to be difficult. Writing software to do this would even be worse than having to do it in the first place. I know I can do this in excel; kinda, but with the amount of records I have its proving to be difficult over a million.

  • compare windows server for patch/update/hotfix installs

    - by user12002221
    Are there any tools that can be used to connect to windows 2008 servers, and get a comparison of the installed patches/updates on the servers, showing what is installed on one and not on the other? This is to help isolate an issue we are seeing on a specific windows server, in a load balanced setup. There is a certain performance/locking issue, which is mitigated whenever one of the servers is disabled. Please share, if you have any suggestions. Thanks in advance!

  • Excel: How to Compare Column Values in a Row

    - by spazzie
    I have a bunch of comparison data and a lot of entries being compared. As an example, say my sheet looks like this, give or take a few columns: Item Price1 Quantity1 Price2 Quantity2 Price3 Quantity3 001 $123 12 $456 24 $789 48 002 $100 95 $200 5 $300 51 For each item (row), I want to be able to look at all of the Quantity columns and find which one has the highest quantity. Ideally I'd be able to run a condition of some sort on the entire excel sheet at once, and it would highlight in red the highest quantity. So the results would be a red "48" (qty3) for Item 001 and a red "95" (qty1) for Item 002. Only the color would change, not any data, and no new rows would need to be created. Let me know if you need more info

  • Sorting arrays with cyclic compares (infinite loop?)

    - by Tiago
    Hi, I have some objects that have 3 sorting options: quality, quatity and a compare against the other object, sorted by that order. - (NSComparisonResult) compare: (MyObject *) obj { if (self.quality > obj.quality) return NSOrderedAscending; else if (self.quality < obj.quality) return NSOrderedDescending; if (self.quantity > obj.quantity) return NSOrderedAscending; else if (self.quantity < obj.quantity) return NSOrderedDescending; if ([self betterThan: obj]) return NSOrderedAscending; if ([obj betterThan: self]) return NSOrderedDescending; return NSOrderedSame; } My problem is that, the betterThan: method might cause a cyclic compare if the objects have the same quality and quantity, and I want to return any sort order in that case. For example, A, B and C have the same quality/quantity, but A betterThan: B => YES B betterThan: C => YES C betterThan: A => YES Solutions? Thanks.

  • iPhone contacts app styled indexed table view implementation

    - by KSH
    My Requirement: I have this straight forward requirement of listing names of people in alphabetical order in a Indexed table view with index titles being the starting letter of alphabets (additionally a search icon at the top and # to display misc values which start with a number and other special characters). What I have done so far: 1. I am using core data for storage and "last_name" is modelled as a String property in the Contacts entity 2.I am using a NSFetchedResultsController to display the sorted indexed table view. Issues accomplishing my requirement: 1. First up, I couldn't get the section index titles to be the first letter of alphabets. Dave's suggestion in the following post, helped me achieve the same: http://stackoverflow.com/questions/1112521/nsfetchedresultscontroller-with-sections-created-by-first-letter-of-a-string The only issue I encountered with Dave' suggestion is that I couldn't get the misc named grouped under "#" index. What I have tried: 1. I tried adding a custom compare method to NSString (category) to check how the comparison and section is made but that custom method doesn't get called when specified in the NSSortDescriptor selector. Here is some code: `@interface NSString (SortString) -(NSComparisonResult) customCompare: (NSString*) aStirng; @end @implementation NSString (SortString) -(NSComparisonResult) customCompare:(NSString *)aString { NSLog(@"Custom compare called to compare : %@ and %@",self,aString); return [self caseInsensitiveCompare:aString]; } @end` Code to fetch data: `NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"last_name" ascending:YES selector:@selector(customCompare:)] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"lastNameInitial" cacheName:@"MyCache"];` Can you let me know what I am missing and how the requirement can be accomplished ?
