  • Why won't anyone accept public fields in C#?

    - by Dmitri Nesteruk
    Seems like every C# static analyzer wants to complain when it sees a public field. But why? Surely there are cases where a public (or internal) field is enough, and there is no point in having a property with its get_ and set_ methods? What if I know for sure that I won't be redefining the field or adding to it (side effects are bad, right?) - shouldn't a simple field suffice?

  • Finding inline style with lxml.cssselector

    - by ropa
    New to this library (no more familiar with BeautifulSoup either, sadly), trying to do something very simple (search by inline style): <td style="padding: 20px">blah blah </td> I just want to select all tds where style="padding: 20px", but I can't seem to figure it out. All the examples show how to select td, such as: for col in page.cssselect('td'): but that doesn't help me much.

  • java double[][] - display as image

    - by joe_shmoe
    Hi all, just wondering if there is a simple way in java to display the contents of say 16x16 array of doubles [0..1] as a greyscale image (ala matlab)? using an unfamiliar matrix library, so I'd like to check that I'm on the right track. don't really care if it is slow or ugly, or if it requires external library - it's just there for a quick look, so as long as it works, I'm fine.

  • How to trim whitespace from bash variable?

    - by too much php
    I have a shell script with this code: var=`hg st -R "$path"` if [ -n "$var" ]; then echo $var fi But the conditional code always executes because hg st always prints at least one newline character. Is there a simple way to strip whitespace from $var (like trim() in php)? or Is there a standard way of dealing with this issue? I could use sed or awk, but I'd like to think there is a more elegant solution to this problem.

  • Django - Better evaluation of relationship at the model level

    - by Brant
    Here's a simple relational pair of models. class Shelf(models.Model): name = models.CharField(max_length=100) def has_books(self): if Book.objects.filter(shelf=self): return True else: return False class Book(models.Model): shelf = models.ForeignKey(Shelf) name = models.CharField(max_length=100) Is there a better (or alternative) way to write the "has_book" method? I'm not a fan of the double database hit but I want to do this at the model level.

  • Silverlight project fails to compile

    - by AngryHacker
    I have a Silverlight 3 project in VS2008. Today, for whatever reason, I get an error when compiling. Configuration system failed to initialize It reports the error on Line 1, Column 1 for every .xaml file in the project. I did a repair on VS2008, reinstalled all the Silverlight 3 bits (e.g. SDK, VS2008 tools and the Controls Toolkit), but the problem still persists. Am I missing something simple?

  • Problem with y-axis in Matlab Diagram

    - by Claus
    Hi, I am drawing a simple bar diagram in Matlab. The problem is, that the value at x = 0 lets the y-axis disappear partially. Is there a way to bring the y-axis to the front instead of hiding between the y-value for x=0? Is there any option I can make sure the y-axis is always in the front? Many thanks, Claus

  • once more: .htaccess - RewriteRules working, but browser address bar displaying full (unfriendly) URL

    - by audio.zoom
    Hi, I can't seem to find my problem with this really simple .htaccess file: Options -Indexes Options +FollowSymLinks RewriteEngine on RewriteBase /d/ #drupal style url rewriting RewriteRule ^([^.]*)$ index.php?path=$1 [L] It works as intended for everything except the root url with no slash. So it rewrites and passes the hidden get querystring to my pages for localhost/d/x/y/z as ?path=x/y/z and localhost/d/ as ?path= (blank) but... localhost/d works, but now appears in the address bar as this ugly monster: http://localhost/d/?path=/Users/audiozoom/Documents/webroot/d What could be the problem?

  • groovyx.net.ws.WSClient is having problems with ''soapenc:Array' Any workaround?

    - by ?????
    I'm trying to call a webservice (implemented with a .NET/ASP system) from groovy/grails using WSClient. I have no trouble accessing this service using the SOAPClient debugger (Todd Ditchendorf's program for OSX), but when i try it via groovy/grails, I get the error undefined simple or complex type 'soapenc:Array' Is there any solution? Looking at it with wireshark: It seems to have thrown this error even before it gets a chance to perform the transaction. The error is thrown right after WSClient has downloaded the second of two schemas referenced in he WSDL.

  • Quartz Cron Trigger with Spring - triggering new cron before last ended

    - by Trick
    Simple question, I think. I have org.springframework.scheduling.quartz.CronTriggerBean triggering one job once a day. Because this method can last a long time (over 24 hours), will the next day at the same time a new job be executed if the last one is not ended yet? If yes - is it possible to turn off executing new jobs until the last one is finished? My method is trans-coding videos and some days there a lot of videos and could last long.

  • NHibernate (3.1.0.4000) NullReferenceException using Query<> and NHibernate Facility

    - by TigerShark
    I have a problem with NHibernate, I can't seem to find any solution for. In my project I have a simple entity (Batch), but whenever I try and run the following test, I get an exception. I've triede a couple of different ways to perform a similar query, but almost identical exception for all (it differs in which LINQ method being executed). The first test: [Test] public void QueryLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .FirstOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.FirstOrDefault(IQueryable`1 source) The second test: [Test] public void QueryLatestBatch2() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .OrderBy(x => x.Executed) .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.SingleOrDefault(IQueryable`1 source) However, this one is passing (using QueryOver<): [Test] public void QueryOverLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.QueryOver<Batch>() .OrderBy(x => x.Executed).Asc .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); Assert.That(batch.Executed, Is.LessThan(DateTime.Now)); } } Using the QueryOver< API is not bad at all, but I'm just kind of baffled that the Query< API isn't working, which is kind of sad, since the First() operation is very concise, and our developers really enjoy LINQ. I really hope there is a solution to this, as it seems strange if these methods are failing such a simple test. EDIT I'm using Oracle 11g, my mappings are done with FluentNHibernate registered through Castle Windsor with the NHibernate Facility. As I wrote, the odd thing is that the query works perfectly with the QueryOver< API, but not through LINQ.
