• How do I flip a column in mysql that has data structured: 'last name, first name'?

  - by ggg

  I want to create a new column in a MYSQL table that has Fn Ln instead of Ln, Fn. Most of my data is printed Fn Ln. Another idea is to incorporate a string function each time there is an output (php based) but that seems to waste resources. Finally, I couldn't find the syntax (loop or foreach) for my php function anyway. Here is the working php function that I got from a previous post: $name = "Lastname, Firstname"; $names = explode(", ", $name); $name = $names[1] . " " . $names[0];

• Adding LDAP OU using Net::LDAP

  - by lupindeterd

  What is the correct syntax of adding an OU using Net::LDAP, I tried the following: #!/usr/bin/perl -w use 5.10.1; use strict; use Net::LDAP; use Data::Dumper; my $ldap = Net::LDAP->new("192.168.183.2") or die "$@"; my $mesg = $ldap->bind( "cn=admin,dc=lab,dc=net", password => 'xxx' ); $mesg = $ldap->add( "ou=Users,dc=lab,dc=net", attrs => [ 'ou' => 'dc=Users', 'objectClass' => [ 'top', 'organizationalUnit' ] ] ); say $mesg->error; say $mesg->code; And got the following error: value of naming attribute 'ou' is not present in entry 64 However using the ldapmodify command line, and using this following ldif, works: dn: ou=Users,dc=lab,dc=net changetype: add objectclass: top objectclass: organizationalUnit ou: Users

• What is prefered method to set consistence font-size and line height for website using em?

  - by metal-gear-solid

  What is the best method to set cross-browser consistence typography (font-size and line height) for whole site using em for Fixed width {Width:970px}, centered website? I usually get design from client with multiple font size and line heights at various places in design. for some good reason i still use em without getting nested element problem and font-size inconsistencies in IE and others. then after setting how to manage and update easily ,and how to calculate ems I want to set easily manageable font sizes and I want to set Line height manually (because it can be different for various places in design. And for which things we should define line-height or for which not? How to set font-size and line-height to get consistent result. and if i'm using em for font-sizing then should i also use bottom-margin of h1, p, li etc in em? HTML {} BODY {} P {} a {} ul li a {} ul li ul li a {} p img {float:left} td,th { }

• ZeroC Ice "checked casts" in Scala

  - by Alexey Romanov

  ZeroC Ice for Java translates every Slice interface Simple into (among other things) a proxy interface SimplePrx and a proxy SimplePrxHelper. If I have an ObjectPrx (the base interface for all proxies), I can check whether it actually has interface Simple by using a static method on SimplePrxHelper: val obj : Ice.ObjectPrx = ...; // Get a proxy from somewhere... val simple : SimplePrx = SimplePrxHelper.checkedCast(obj); if (simple != null) // Object supports the Simple interface... else // Object is not of type Simple... I wanted to write a method castTo so that I could replace the second line with val simple = castTo[SimplePrx](obj) or val simple = castTo[SimplePrxHelper](obj) So far as I can see, Scala's type system is not expressive enough to allow me to define castTo. Is this correct?

• findManyToManyRowset with Zend_Db_Table_Select

  - by Typeoneerror

  Hello. I'm trying to use a select object to filter the results of a many to many rowset. This call works great: $articles = $this->model->findArticlesViaArticlesUsers(); This however does not: $articles = new Default_Model_Articles(); $articleSelect = $articles->select(); $articleSelect->where("status = 'published'") ->order("date_published DESC") ->limit(1); $articles = $this->model->findArticlesViaArticlesUsers($articleSelect); That throws the following error: exception 'Zend_Db_Select_Exception' with message 'You cannot define a correlation name 'i' more than once' I can't figure out how to successfully get "articles that have the status of 'published'" using the magic many-to-many relationship (nor findManyToManyRowset). I'm at the end of my rope and thinking of just writing the sql manually. Any ideas?

• Mongomapper query collection problem

  - by kylemac

  When I define the User has_many meetings, it automatically creates a "user_id" key/value pair to relate to the User collections. Except I can't run any mongo_mapper finds using this value, without it returning nil or []. Meeting.first(:user_id = "1234") Meeting.all(:user_id = "1234") Meeting.find(:user_id = "1234") All return nil. Is there another syntax? Basically I can't run a query on the automatically generated associative ObjectId. # Methods class User include MongoMapper::Document key :user_name, String, :required = true key :password, String many :meetings end class Meeting include MongoMapper::Document key :name, String, :required = true key :count, Integer, :default = 1 end # Sinatra get '/add' do user = User.new user.meetings "foobar") #should read: Meeting.new(:name = "foobar") user.save end get '/find' do test = Meeting.first(:user_id = "4b4f9d6d348f82370b000001") #this is the _id of the newly create user p test # WTF! returns [] end

• gcc-4.2 failed with exit code 1 iphone

  - by SKayser

  Hi, I've seen this error with different variations on discussion forums but being a non programmer I'm not sure how to progress this. Basically I have code which I found to help me with changing the background colors of cells on a grouped uitableview. The code introduced a line as such: CGContextAddArcToPoint(c, minx, miny, midx, miny, ROUND_SIZE); This gave an error indicated that it wasn't declared, so I added to my .h file the following under import uikit: #import <UIKit/UIKit.h> #define ROUND_SIZE 10 Now it shows that I have an error: Command/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1 iphone Some discussions talk about libraries but because I don't have a programming background I don't understand what to do. I also see that some people show a log output but I'm not sure where that comes from as I don't get any debug windows because I'm guessing it doesn't get that far. I simply click 'Build and Go' and I get this error in the Message window. Any thoughts?

• Delphi 7: how to execute shell command and check the result?

  - by mawg

  I'm using Delphi 7 and can't predict the target version of Windows. I need to create a database (probably MySql, but might be something else) and define some table structures. I do not need to populate any data. Unfortunately, all of the ADO components seem to expect that a database already exists and they will then allow you to manipulate it. So, since it's only a few simple commands, I thought that I might as well use ShellExectute(). Agree? Disagree? Can anyone give me a sample code which will attempt to run "MySql --version" and let me check the result? After that I should be able to figure it out for myself. Thanks.

• Teradata equivalent of persisted computed column (in SQL Server)

  - by Cade Roux

  We have a few tables with persisted computed columns in SQL Server. Is there an equivalent of this in Teradata? And, if so, what is the syntax and are there any limitations? The particular computed columns I am looking at conform some account numbers by removing leading zeros - an index is also created on this conformed account number: ACCT_NUM_std AS ISNULL(CONVERT(varchar(39), SUBSTRING(LTRIM(RTRIM([ACCT_NUM])), PATINDEX('%[^0]%', LTRIM(RTRIM([ACCT_NUM])) + '.' ), LEN(LTRIM(RTRIM([ACCT_NUM]))) ) ), '' ) PERSISTED With the Teradata TRIM function, the trimming part would be a little simpler: ACCT_NUM_std AS COALESCE(CAST(TRIM(LEADING '0' FROM TRIM(BOTH FROM ACCT_NUM))) AS varchar(39)), '' ) I guess I could just make this a normal column and put the code to standardize the account numbers in all the processes which insert into the table. We did this to put the standardization code in one place.

• built-in schema datatype for html / xhtml

  - by John Clements

  Is there a built-in schema datatype for xhtml data? Suppose I want to specify a "boozle" element that contains two "woozles", each of which is arbitrary xhtml. I want to write something like this, using the relax NG compact syntax: namespace nifty = "http://brinckerhoff.org/nifty/" start = element nifty:boozle {woozle, woozle} woozle = element nifty:woozle {xhtml} Unfortunately, xmllint then signals this error: ./lab.rng:43: element ref: Relax-NG parser error : Reference xhtml has no matching definition ./lab.rng:43: element ref: Relax-NG parser error : Internal found no define for ref xhtml So my question is this: is there something sensible that I should put in place of "xhtml" above?

• How to get real Integer Overflows in Matlab/Octave

  - by marvin2k

  Hi there. I'm working on a verification-tool for some VHDL-Code in Matlab/Octave. Therefore I need datatypes which generate "real" overflows: intmax('int32') + 1 ans = -2147483648 Lateron, it would be helpfull if i can define the bitwidth of a variable... But that is not so important... When I build a C-like example, where a variable gets increased until it's smaller than zero, it spins forever and ever... test = int32(2^30); while (test > 0) test = test + int32(1); end Another approach i tried was a custom "overflow"-routine which was called everytime after a number is changed. This approach was painfully slow, not practicable and not working in all cases at all...

• HTML text-area editor for code that traps TAB key

  - by Cristi Cotovan

  Hello, I have looked for months now, for JavaScript-based HTML editor I can embed onto my web pages to replace a TEXTAREA, but to enable me to edit CODE in a friendly, closer to a real editor, way. All editors I've tried (RadEditor from Telerik, FCKEditor, TinyMCE, etc etc), do not trap the TAB key, very useful when editing HTML code onto a page, to help format the code properly. I'm not talking about syntax highlighting, as that would be an awesome plus. But I am mainly wondering if there is such an editor. I'd appreciate being pointed in the right direction.

• More pythonic way to iterate

  - by fmark

  I am using a module that is part of a commercial software API. The good news is there is a python module - the bad news is that its pretty unpythonic. To iterate over rows, the follwoing syntax is used: cursor = gp.getcursor(table) row = cursor.Next() while row: #do something with row row = cursor.next() What is the most pythonic way to deal with this situation? I have considered creating a first class function/generator and wrapping calls to a for loop in it: def cursor_iterator(cursor): row = cursor.Next() while row: yield row row = cursor.next() [...] cursor = gp.getcursor(table) for row in cursor_iterator(cursor): # do something with row This is an improvement, but feels a little clumsy. Is there a more pythonic approach? Should I create a wrapper class around the table type?

• Best Practice to write Connection string for heavy traffic ASP.NET Web Application

  - by hungrycoder

  What is the best way to define connection string for a web application that has minimum 500 live users on the internet in terms of connection pooling. And load factors to consider? Suppose I have connection string as follows: initial catalog=Northwind; Min Pool Size=20;Max Pool Size=500; data source=localhost; Connection Timeout=30; Integrated security=sspi" as Max Pool Size is 500 and as live users exceed 500 say 520 will the remaining 20 users experience slower page load?? Or what if I have connection string as follows which doesn't talks anything about pooling or Connection time out? How the application behaves then? initial catalog=Northwind; data source=localhost; Integrated security=sspi" I'm using "Using statements" however to access the MYSQL database.

• "The left hand side of an assignment must be a variable" due to extra parentheses

  - by polygenelubricants

  I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parentheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?

• Csharp component which generates fragmens with highlights for diffs for 2 strings

  - by MicMit

  I need C# equivalent ( ideally open source ) which is similar to Delphi DLL. I am currently using the wrapper ( C# syntax is provided , but it is a call from a different language ) zdiff( string ref str1, string ref str2, int range , int trim ) it calls inside str1 = GetHiDiff(@str1,1,trim) str2 = GetHiDiff(@str1,2,trim) where function GetHiDiff(s:pchar; sIndex:integer; wtrim:integer): pchar; stdcall; What it does it returns a left fragment html of str1 and a right html fragment of str2 with diffs highlighted as strings are passed by reference. Range parameter determines the size of html fragment. Not sure what trim 0 does.

• Castle Windsor config pointing to connectionStrings section in web.config

  - by Georgia Brown

  I want to inject a connection string into my repository but ideally, I want this connection string to be in my web.config connectionStrings section rather than in my windsor config. Is this possible? I know I can use the fluent interface and achieve this easily but my bosses want an xml config file. I also know that I can define a property and use that in my windsor config to pass the parameter in, but I have other code that reads the connectionstring from the web.config directly and do not really want two places with the same connectionString.

• How do I access variables with hyphenated names in Smarty?

  - by abeger

  I've got a PHP page that parses an XML file with SimpleXml, then passes that object to a Smarty template. My problem is that the XML file has hyphens in its tag names, e.g. video-player. In PHP, this is no problem, I just use $xml->{'video-player'} and everything's fine. Smarty, on the other hand, throws a fit when I try to use that syntax. The only solution I've come up with so far is to use a variable to store the name, e.g., { assign var=name value="video-player" } { $xml->$name } But this isn't terribly graceful to say the least. Is there another, better, approach to referring to a hyphenated variable name in Smarty?

• How can I reuse my javascript code between client and server?

  - by Chris Farmer

  I have some javascript code that includes an ANTLR-generated lexer and parser, and some associated syntax tree evaluation functionality. This code runs in the browser in my web app to support users who author code snippets which process scientific data. Now I'd like to do some additional background processing on the server using the same generated parser. I would prefer not to have to re-implement this stuff in C# and have multiple bits of code that did the exact same thing. Performance isn't as critical to me as eliminating duplication, since this is a background process. So, how can I call into my javascript code from C#? And how can I format my script so that it plays nicely with my .NET web app?

• How to write scripts that can run in bash and csh?

  - by Victor Liu

  I'm not sure if this is even possible, but is there a way to write shell scripts that can be interpreted by both the Bourne shell as well as C shell? I want to avoid simply checking for the shell and running a shell-specific code. If this is possible, are there any guides on how to do it? I have always written my scripts for Bourne shell syntax, and I know next to nothing about csh, so this may be a stupid question. I have Google'd for the differences between shells, but there is little information (as far as I can tell) on its implications for scripting.

• Regular expression in BASH

  - by Ryan

  Hello everyone, I was hoping someone could answer my quick question as I am going nuts! I have recently started learning regular expressions in my Java programming however am a little confused how to get certain features to work correctly directly in BASH. For example, the following code is not working as I think it should. echo 2222 | grep '2\{2\}' I am expecting it to return: 22 I have tried variations of it including: echo 2222 | grep '2{2}' echo 2222 | grep -P '2\{2\}' echo 2222 | grep -E '2\{2\}' However I am completely out of ideas. I'm sure this is a simple parameter / syntax fix and would love some help! P.S I've done tons of googling and every reference I find does not work in BASH; regex's can run on so many different platforms and engines =/

• Can I have a shell alias evaluate a history substitution command?

  - by Brandon

  I'm trying to write an alias for cd !!:1, which takes the 2nd word of the previous command, and changes to the directory of that name. For instance, if I type rails new_project cd !!:1 the second line will cd into the "new_project" directory. Since !!:1 is awkward to type (even though it's short, it requires three SHIFTed keys, on opposite sides of of the keyboard, and then an unSHIFTed version of the key that was typed twice SHIFTed), I want to just type something like cd- but since the !!:1 is evaluated on the command line, I (OBVIOUSLY) can't just do alias cd-=!!:1 or I'd be saving an alias that contained "new_project" hard-coded into it. So I tried alias cd-='!!:1' The problem with this is that the !!:1 is NEVER evaluated, and I get a message that no directory named !!:1 exists. How can I make an alias where the history substitution is evaluated AT THE TIME I ISSUE THE ALIAS COMMAND, not when I define the alias, and not never? (I've tried this in both bash and zsh, and get the same results in both.)

• Mixin or Trait implementation in AS3?

  - by Brian Heylin

  I'm looking for ideas on how to implement a Mixin/Trait style system in AS3. I want to be able to compose a number of classes together into a single object. Of course this is not a language level feature of AS3, but I'm hoping that there is maybe some way to do this using prototype based techniques or maybe some bytecode hacking that I believe AsMock uses to implement it's functionality. An existing Java example is Qi4J where the user define interfaces that the Qi4j framework implements based on metadata tags and coding by convention. Has anyone any ideas on how to get the Mixin/Trait concept working within AS3?

• How to localize HeaderText in GridView or validation controls?

  - by Janusz

  I cannot figure out why HeaderText or validation controls always fallback to default culture - even though rest of the controls are in correct culture. I have a gridView with HeaderText specified in this way <asp:BoundField DataField="totalSales" HeaderText="<%$ Resources:Strings,TotalSales %>" /> In the same way I have validation controls and they can't be localized. Only this syntax does work <%= Resources.Strings.Payments %> I set different culture in Master page using this statement in Page_Init Me.Page.Culture = "pl-PL" Me.Page.UICulture = "pl-PL" Can anyone spot what's wrong? I have been Googling it for last few days without success. Thanks!

• How do people prove the correctness of Computer Vision methods?

  - by solvingPuzzles

  I'd like to pose a few abstract questions about computer vision research. I haven't quite been able to answer these questions by searching the web and reading papers. How does someone know whether a computer vision algorithm is correct? How do we define "correct" in the context of computer vision? Do formal proofs play a role in understanding the correctness of computer vision algorithms? A bit of background: I'm about to start my PhD in Computer Science. I enjoy designing fast parallel algorithms and proving the correctness of these algorithms. I've also used OpenCV from some class projects, though I don't have much formal training in computer vision. I've been approached by a potential thesis advisor who works on designing faster and more scalable algorithms for computer vision (e.g. fast image segmentation). I'm trying to understand the common practices in solving computer vision problems.
