• How to test unescaped &nbsps; as a whitespace

  - by gleery

  I use apache common lang to unescape a block of html text which contains &nbsp;, I want to filter out blocks that contains only whitespaces. But I can't test the   as a whitespace. It's not in the normal whitespace list(http://en.wikipedia.org/wiki/Whitespace_character), and I try to print its Hex form by calling Character.getNumericValue which return -1. &nbsp should be a whitespace,isn't? But How can I test it?

• Good practice : compare a value with a boolean?

  - by NLemay

  Most of the time, I prefer to write this : if(isWelcome() == true){} if(isWelcome() == false){} instead of this if(isWelcome()){} if(!isWelcome()){} Because I feel that it is easier to read (but I do understand that it doesn't make sense). I would like to know if there is a common agreement about this practice. What most developer do? And I'm wondering if the compiler is doing the extra comparaison, or if it understand that it is useless.

• Help needed to construct a SQL query

  - by song202y

  Need your help to get the list of suggested friends (who aren't friends of the current user but are friends of 2 or more of the current user's friends). The primary ordering should put people at the same school at the top, and the secondary ordering should put people with more common friends (that is, the number of people who are friends of that person and the current user) near the top. Users: user_id PK, user_name Profiles: user_id PK, school_name, ... Friendships: id PK, user_id FK, friend_id FK Thank you in advance. Joe

  - by goodan

  Is there a jquery way or plugin to detect the visitor's browser window size when they first come to the page and auto stretch the browser for them if it's too small? It's a pretty common thing that I've seen done a few times, so I'm guessing someone here will know about it.

• What is the most Interesting and innovative IDE?

  - by Branislav Abadjimarinov

  As every programmer knows tools are important and there is no tool more important for a developer than the IDE you use to code. In the last few years the IDE-s fall into standards and it is not common to see innovation in this area. What IDE-s you can recommend as innovative and what new ideas and paradigms they introduced?

• Updating an atom with a single value

  - by mikera

  I have a number of atoms in my code where a common requirement is to update them to a new value, regardless of the current value. I therefore find myself writing something like this: (swap! atom-name (fn [_] (identity new-value))) This works but seems pretty ugly and presumably incurs a performance penalty for constructing the anonymous closure. Is there a better way?

• How to implement automatic replacement of typos in Delphi2010

  - by sum1stolemyname

  I am looking for a way to develop a plugin for Delphi 2010IDE and have yet to find any information on that topic, not even on how to get started. What I want to accomplish is some kind of auto-spellchecker wich can be given a list of common typos (flase instead of false, .cerate instead of .create and the like) and replace them with the intended word. Do you know of a tutorial on plugin development, or maybe an open source plugin which i could base my work on?

• C#, XmlDocument, and special ISO Latin characters

  - by Trent

  I'm trying to load up xml into an XmlDocument, but it doesn't recognize the encoded '&eacute' and throws an error 'An error occurred while parsing Entity Name'. Now I can add a custom entity set in a DTD of my xml, so the XmlDocument loads properly. But what I'm hoping is that I can reference a url that has a common set of these ISO Latin encoded characters. Is this possible, or do I need to inject a custom list of DTD sets?

• Powershell interact with open Excel

  - by HKK

  To interact with excel in Powershell it is common to start a new excel as follows: $x = New-Object -comobject Excel.Application Instead of that I have an open Excel process already.

  What are the common design approaches taken in loading data from a typical Entity-Relationship OLTP database model into a Kimball star schema Data Warehouse/Marts model?

Where/How do you manage the transformation process - in the database as sprocs, dts/ssis packages, or SQL from application code?

• Reinject dependencies of a freshly deserialized object

  - by NathanE

  If a program has literally just deserialized an object (doesn't really matter how, but just say BinaryFormatter was used). What is a good design to use for re-injecting the dependencies of this object? Is there a common pattern for this? I suppose I would need to wrap the Deserialize() method up to act as a factory inside the container. Thanks!

• How to justify text on a TextView made easy- Android

  - by Juan

  I'm looking for a simple way to forget that I'm using a WebView to have justified text in my TextView. Has someone made a custom view for this? I'm well aware that I can do something like this: WebView view = new WebView(this); view.loadData("my html with text justification","text/html","utf-8"); But it gets ugly when you want to set the size, the color or other common properties of the TextView, there must be a more convenient way of doing it.

• Does content always have to be in chronological order in an RSS feed?

  - by Chris Henry

  I run a site where users can upload content that is displayed in a gallery where other users can sort and filter that content. While implementing RSS feeds, I was wondering how common it was for an RSS feed to display items in an order that's different from chronological. For example, displaying content by Most Views first. This could be useful for someone wanting to keep tabs on trending content. How do RSS readers handle this, since most RSS feeds are ordered chronologically?

• Database Patterns

  - by Onorio Catenacci

  Does anyone know of papers/books/etc. that document patterns for databases? For example, one common rule of thumb is that every table should have a primary key and that the key should be devoid of information content. So I was wondering if anyone had written a book or published papers regarding design patterns for designing relational databases?

• Question with "extern" in C

  - by why

  When programming, I would like to split one large file(which contains main function) to many small files, so there is one common case: functions in small files can modify the var from main file, so i think extern is very useful! for instance: in main.c extern int i = 100; in small.c extern int i; fprintf(stdout, "var from main file: %d\n", i); I just want to know is my understanding right?

I am wondering how to redirect stdout to all compiler consoles and also, how do I break when an error occurs while executing that external tool? Answers are sought for modern common compilers. If there is a generic process or if it can be done automatically let me know.

• Hibernate Lazy Loading Proxy Incompatable w/ Other Frameworks

  - by bowsie

  I've come across several instances where frameworks that take POJOs to do some work crap-out with proxied hibernate beans. For example if I xml annotate a bean for framework X and pass it to framework X it doesn't recognise the bean because it is passed the proxied object - which has no annotations for framework X. Is there a common solution to this? I'd prefer not to define the bean as eager loaded, or turn of lazy-loading anywhere in the application. Thoughts? Thanks.

• shared_ptr as class member

  - by idimba

  It's common to declared contained objects as a pointers to that class, while "forward declarating" them in header file. This in order to reduce physical dependencies in code. For example class B; // forward declaration class A { private: B* pB; }; Would it be good idea to declare such a member as shared_ptr, instead of naked pointer? I would prefer scoped_ptr, but AFAIKit it won't be in standard.

• How can I check if a Ruby array includes one of several values?

  - by Colen

  I have two Ruby arrays, and I need to see if they have any values in common. I could just loop through each of the values in one array and do include?() on the other, but I'm sure there's a better way. What is it? (The arrays both hold strings.) Thanks.
