• Google App Engine, Java, and HTTP Performance

  - by polyclef

  A friend and I are currently working on a turn-based game with chat with both desktop browser and Android clients, with Google App Engine as the server. We're using the Java API for GAE and using HTTP for communication with the server. We've implemented simple chat functionality, and we're getting undesirable latencies 1-3 seconds from both the browser and Android clients while just posting simple one-word chat messages. My friend thought it would be best to use XMPP instead of HTTP, but we want to use a Google Accounts cookie for authentication from the Android client, and according to the GAE documentation, XMPP clients cannot use a Google Accounts cookie and must use the user's password. Does anyone have any suggestions as to where the latency might be coming from, how to troubleshoot it, and/or what to do about it? Also, is anyone aware of any opensource implementations of chat (or something similar) on GAE done in Java? Can't seem to find any.

• Why do contains()/indexOf() in a Java collections use o.equals(e) and not e.equals(o)?

  Why are the methods contains() and indexOf() in the Java collections framework defined using o.equals(e) and not e.equals(o) (where o is the argument of the methods and e is the element in the collection)? Anyone know the reasons of that?

• .net 3.5 message framing

  - by Rob

  We have message framing working by using a lengh prefix but using .NET 2.0 beginSend/BeginReceive. Is message framing any different in 3.5, if so how should we implement it using the new framework? Are there any useable examples out there which focus purely on message framing using 3.5? Many thanks

• Transitioning from the web to the desktop

  - by Paul Anderssen

  Can anyone recommend a language, library, framework or book which focuses on GUI programming from the perspective of a web developer? I have experience in web development, for example HTML/AJAX/PHP/MySQL among similar technologies. However, I have never programmed my own back-end, or any kind of standalone program. Does anyone have experience making this transition, and what would I best study to help make the leap from the browser to creating programs with GUIs (primarily for Windows)?

• Automatic form generation software

  - by Jonathan

  Hi! I'm using winforms. I spend a lot of time drawing forms (maybe not a lot, but it is a boring task). To sum up... I want to develop a simple aplication that connect to a sql server database, let the user to select a table, and put the controls in a form for me (generate the designer code), based on the tipe of each column. Then my app will name each control like the column of the table, set the maxlengh property (if the type is varchar), and create a label with the same text near the control. If the column is a FK, then the app will draw a combobox and so on. I saw that Telerik Open ORM make something like this, but I only need a simple app for the IU Generation. If the same day I finish my little application I discover a tool that make the same... I will feel myself stupid :D Are there any tool out there that do this work for me? Thanks

• How do I get jquery & mootools to play nice?

  - by Vic

  I've been using Mootools 1.2.4 as my JS framework of choice. I've added Checkout by Amazon to one of my pages, and they inject jQuery 1.2.6 into the page and messes up my dollar function (among other things). I have control over Mootools, but not jQuery. I would rather not rewrite my existing code to accomodate jQuery since Checkout by Amazon was an afterthought and plug-in element. Any thoughts or suggestions are recommended. Thanks!

• Difference between a Deprecated and Legacy API?

  - by Vaibhav Bajpai

  I was studying the legacy API's in the Java's Collection Framework and I learnt that classes such as Vector and HashTable have been superseded by ArrayList and HashMap. However still they are NOT deprecated, and deemed as legacy when essentially, deprecation is applied to software features that are superseded and should be avoided, so, I am not sure when is a API deemed legacy and when it is deprecated.

• Best Performing ORM for .NET

  - by steve_c

  I'm curious if anyone has done any performance comparisons with any or all of the main players in the .NET ORM space. Specifically I'm interested in comparisons between the following: Linq to SQL NHibernate LLBL Gen Entity Framework Though it seems people don't really consider Linq to SQL a true ORM, I am still including it in this list. Some performance metrics would be nice to see.

• How are get and set methods on javabeans called by frameworks?

  - by testymctesttesttest

  If you have a bean with a getFoo method, how does whatever framework you're using know how to call the getFoo method when you ask for the value of foo? Is this done using the reflection API? Or is it somehow done using annotations? Obviously I know how you can derive the method given the name of the property, I just don't know how the method is invoked.

• how to turn visual studio windows forms project into an application?

  - by Pieter888

  Hey everyone, I programmed an hour-sheet application and now I would like to publish it so people can install and run it. I've tried the publish function of visual studio 2008 but this gives me a clickOnce application/installer that's really confusing, but it works when I run it, but when I export the installer to another pc it installs it crashes at the end of the install. so I tried just coping the installed files but then the program crashes at startup. Is there a simple way to compile the application to a simple standalone executable or maybe containing a separate folder containing the resources (images/classes)?

• Why is numpy c extension slow?

  - by Bitwise

  I am working on large numpy arrays, and some native numpy operations are too slow for my needs (for example simple operations such as "bitwise" A&B). I started looking into writing C extensions to try and improve performance. As a test case, I tried the example given here, implementing a simple trace calculation. I was able to get it to work, but was surprised by the performance: for a (1000,1000) numpy array, numpy.trace() was about 1000 times faster than the C extension! This happens whether I run it once or many times. Is this expected? Is the C extension overhead that bad? Any ideas how to speed things up?

• MySQL sorting: NULL to the end & use index? Not possible?

  - by Vojto

  Hello fellow experts, I have a huge table and I want simple sorting. It could be so easy. I could just create an index and do some really fast sorting thanks to that index. But my client wants to put NULLs to the end, which is complicates the whole situation. Instead of simple: SORT BY name ASC I have to do SORT BY name IS NULL ASC, name ASC. That would be ok, but it because of that my index is useless, and the sorting is very slow. I don't know if there's a way to solve this problem, but if there is one, I desperately ask for help. :'(
