  - by ggfan

  I am still relatively new to programming and as I start to write longer and more complex codes, it gets very confusing and hard to reread. Are there some general good practices that every programmer should use?

• FOSS solution for a local machine: DNS

  - by Shyam

  Hi, I love my Mac. But I have always found that my DNS lookups are as slow, even while flushing caches and I travel over know roads on the Internet. I was wondering if someone would know something a bit more automatic/intelligent than /etc/hosts and less complex and iron forged as BIND. Thank you for your feedback and answers!

• Javascript: How to detect if a word is highlighted

  - by fterh

  I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.

• Setting custom SQL in django admin

  - by eugene y

  I'm trying to set up a proxy model in django admin. It will represent a subset of the original model. The code from models.py: class MyManager(models.Manager): def get_query_set(self): return super(MyManager, self).get_query_set().filter(some_column='value') class MyModel(OrigModel): objects = MyManager() class Meta: proxy = True Now instead of filter() I need to use a complex SELECT statement with JOINS. What's the proper way to inject it wholly to the custom manager?

  I have complex logic which is not possible (too slow) to run through PHP with Doctrine, so I need to create a stored procedure for this. The logic also includes inserting/updating records in a table using the Timestampable behavior. How do I preserve this behavior in the stored procedure?

• What's the difference between C and C++

  - by Dinah

  I know that C++ has the concept of objects but C doesn't. I also know that pretty much all there is to know about C fits into K & R but the C++ library is vastly more complex. There have got to be other big differences though. What are the major differences between C and C++?

• WPF Label vs TextBlock in Border ?

  - by PaN1C_Showt1Me

  If you know that you have to show tens of texts with a border, would you decide for a Label (which is much complex and resources consuming) or a TextBlock in a Border? . The performance aspect is the one interesting for me now. Thank you !

• Building a custom textbox in GTK

  - by CommuSoft

  I want to make my own GTK# Textbox, the textbox should draw the text and it's cursor on a special way. However keyboard and mouse-handling is quite complex and is also influenced by for instance the operating system (for instance the use of dead keys) Is there a way to build such a control without having to worry about keyboard input? I assume I have to make a textbox control that inherits the original textbox control. How can I handle drawing requests and mouse movements?

  I just finished coding a complex job assignment application where a lot of the work was done using priority queues. When I deployed, however, I discovered the web server ran PHP 5.2. Has there been an implementation for PHP<5.3 that can server as a drop-in replacement for SPLPriorityQueue?

• Combining foreach and using

  - by apoorv020

  I'm iterating over a ManageObjectCollection.( which is part of WMI interface). However the important thing is, the following line of code. : foreach (ManagementObject result in results) { //code here } The point is that ManageObject also implements IDisposable, so I would like to put "result" variable in a using block. Any idea on how to do this, without getting too weird or complex?

• How to build a database from an XSD schema and import XML data

  - by FreshCode

  I have a complex XSD schema and hundreds of XML files conforming to the schema. How do I automate the creation of related SQL Server tables to store the XML data? I've considered creating C# classes from the XSD schema using the xsd.exe tool and letting something like Subsonic figure out how to make a shiny database out of it, but not sure if it's the best way to approach it. Has anyone managed to elegantly import XSD files into SQL Server?

• How to take advantage of subprocess within Django? - Django

  - by RadiantHex

  Hi folks, I'm currently using os.popen() but have been recommended to use subprocess.popen() instead. Any ideas on how I can integrate this? It would be cool and fun to have a Python shell accessible on a Django app. But I reckon that it might be a bit complex to implement. I guess I would have to retrieve the subprocess, as a new request comes in. Any ideas?

• Autorun a removable device in Linux

  - by Zloy Smiertniy

  I have a removable device setup so it autoruns when plugged into a Windows machine and pops up a message giving the owner's information, so it can be returned if lost. Is there a way to do this in Linux as well? It doesn't need to be complex, it can be an option in a right-click menu, or a splashscreen, or anything.

• Which kind of changes can't I do with lightweight migration in Core Data?

  - by dontWatchMyProfile

  I recently tried a lot of different stuff with lightweight migration. These all work: 1) Rename attributes (with renaming identifier specified) 2) Add attributes 3) Add new entity + new attribute + inverse relationship to an already existing entity 4) remove existing entity + relationships to that entity = It almost looks like just about anything can be handled with LM. Did I miss something? In which cases am I getting into trouble and need an some more complex approach?

• AS3: why is this happening?

  - by Bin Chen

  Hi, I just encounter a strange problem: var a:ClassA = new ClassA; var b:ClassA = a; The program keeps running sometime, the a = null, b = null. The program is a complex one, I am sure that no part will touch a, and b. My question is, will the runtime(garbage collector) to collect the memory of "a" and then assign a and b to null? I am confused, thanks!

• How to get a random node from a tree?

  - by ooboo

  It looks easy, but I found the implementation tricky. I need that for a simple genetic programming problem I'm trying to implement. The function should, given a node, return the node itself or any of its children such that the probability of choosing a node is normally distributed relative to its depth (so the function should return mostly middle nodes, but sometimes the root itself or the lowest ones - but that's not really necessary if that makes it significantly more complex, if all any node is chosen with equal probability, that's good enough). Thanks

• How can I estimate server costs for creating an app?

  - by G Dottin

  Im writing up a business plan and im having some trouble with the finance part. I put an estimate on the cost of developers, web designers and everything but server costs. Im not a programmer so I dont know all the details. But how much would you think servers are going to cost for a complex app. I cant get into too many details but it keeps track of user preferences, stores data about the user and there is quite alot of back-end to it.
