• Is there any library to represent SQL queries as objects in Java code?

  - by Pregzt

  I was wondering if there is any library that can be used to represent SQL queries as objects in Java. In the code I have plenty of static variables of type java.lang.String that are hand written SQL queries. I would be looking for library having a nice fluent API that allows me to represent the queries as objects rather than strings. Example: Query q = select("DATE", "QUOTE") .from("STOCKMARKET") .where(eq("CORP", "?")) .orderBy("DATE", DESC);

• Django context processor gets AnonymousUser

  - by myfreeweb

  instead of User. def myview(request): return render_to_response('tmpl.html', {'user': User.objects.get(id=1}) works fine and passes User to template. But def myview(request): return render_to_response('tmpl.html', {}, context_instance=RequestContext(request)) with a context processor def user(request): from django.contrib.auth.models import User return {'user': User.objects.get(id=1)} passes AnonymousUser, so I can't get the variables I need :( What's wrong?

• 64-bit integers in Cython

  - by Homayoon

  I'm trying to interface a C++ library (pHash) with Python using Cython, but I have trouble with some of the types. The library functions use "unsigned long long" and I can't find a way to declare variables and parameters with this type. I searched for a list of the types that I can use with cdef but I found nothing. Can anyone point me to such a list (if it exists) or otherwise suggest a way to use 64 bit types in Cython? Thanks.

• C++: Unsigned negative primitives?

  - by Martijn Courteaux

  In C++ we can make primitives unsigned. But they are always positive. Is there also a way to make unsigned negative variables? I know the word unsigned means "without sign", so also not a minus (-) sign. But I think C++ must provide it.

• Change default global installation directory for node.js modules in Windows?

  - by gremo

  In my windows installation PATH includes C:\Program Files\nodejs, where executable node.exe is. I'm able to launch node from the shell, as well as npm. I'd like new executables to be installed in C:\Program Files\nodejs as well, but it seems impossible to achieve. Setting NODE_PATH and NODE_MODULES variables doesn't change anything: things are still installed in %appdata%\npm by default. How can I change the global installation path?

• How do I push `sed` matches to the shell call in the replacement pattern?

  - by rassie

  I need to replace several URLs in a text file with some content dependent on the URL itself. Let's say for simplicity it's the first line of the document at the URL. What I'm trying is this: sed "s/^URL=\(.*\)/TITLE=$(curl -s \1 | head -n 1)/" file.txt This doesn't work, since \1 is not set. However, the shell is getting called. Can I somehow push the sed match variables to that subprocess?

• How to implement IDisposable properly

  - by Vince

  Hi, I've seen so much C# code in my time as a developer that attempt to help the GC along by setting variables to null or calling Dispose() on classes (DataSet for example) within thier own classes Dispose() method that I've been wondering if there's any need to implement it in a managed environment. Is this code a waste of time in its design pattern? class MyClass : IDisposable { #region IDisposable Members public void Dispose() { otherVariable = null; if (dataSet != null) dataSet.Dispose(); } #endregion }

  I am experimenting with Less Css, and I am using Visual Studio 2010. It would be nice if the editor provided support for syntax highlighting and Intellisense for Less, for instance coloring and suggesting variables. What are my options to get that to work ? Do I need to write a plugin for it, or how would one go about adding this to VS ? Does anything exist for this already ?

• Critiquing PHP-code / PerlCritic for PHP?

  - by jeekl

  I'm looking for an equivalent of PerlCritic for PHP. PerlCritc is a static source code analyzer that qritiques code and warns about everything from unused variables, to unsafe ways to handle data to almost anything. Is there such a thing for PHP that could (preferably) be run outside of an IDE, so that source code analysis could be automated?
