• Rails, using jQuery without jrails

  - by ibuck

  Hello all, I have been trying to convert my rails 2.2.2 app over to jQuery, and would like so without using jrails. The only reference material I can find on the subject is Railscasts Episode 136. Ryan goes over how to use jQuery to post a form and handle the response in a .js.erb file. My questions is has anyone tried to use jQuery with .js.erb files with anchors as the trigger? As a replacement for "link_to_remote". I have gotten jQuery to do a .get to submit this link on click to the controller, but I cannot seem to get it to go into the .js.erb file. Thanks

• Is there any way to simplify a verbose SQL INSERT INTO(..) query?

  - by Soundar Rajan

  I have a table with one id (autonumber) field and 50 other fields. The table is normalized, these are 50 material properties etc. I want to copy a record from this table into the same table - only the autoincrement id will be different. The query I am using now is INSERT INTO tableName (field1,field2,....field50) SELECT field1,field2,....field50 from tableName WHERE autoid=1234; Note that I have to type in ALL the 50 field names, twice! Is there any way to shorten this query so I don't have to type all of them? Thanks.

• How to choose the right web application framework?

  - by thenextwebguy

  http://en.wikipedia.org/wiki/Comparison_of_web_application_frameworks Since we are ambitiously aiming to be big, scalability is important, and so are globalization features. Since we are starting out without funding, price/performance and cost of licences/hardware is important. We definitely want to bring AJAX well present in the web interface. But apart from these, there's no further criteria I can come up with. I'm most experienced with C#/ASP.net, PHP and Java, in that order, but don't turn down other languages (Ruby, Python, Scala, etc.). How can we determine from the jungle of frameworks the one that suits best our goal? What other questions should we be asking ourselves? Reference material: articles, book recommendations, websites, etc.?

• Android and SQLite using the SQLiteOpenHelper

  - by tunneling

  I have a SQLite database, and several tables within that database. I am developing a DBAdapter for each table within the database. (reference Reto Meier's Professional Android 2 Application Development, Listing 7.1). I am using the adb shell to interface with the database from the command line and see that the database is being populated as I expect. Occasionally, I want to drop a table so that I can ensure it's being built properly, from scratch. The problem is that SQLiteOpenHelper only checks to see if the database exists. Is there a typical solution to writing a helper to also see that the table(s) exists? Basically once I drop a table, the helper checks to see that the database exists and assumes all is well. Also, the CREATE_DATABASE string used in the reference above only creates the one table. Should I consider using the DBAdapter for an adapter to ALL of my tables? That doesn't seem as clean to me.

• How to use MOV instruction in ARM with an immediate number as the second operand

  - by Summer_More_More_Tea

  Hi everyone: I just begin to study ARM assembly language, and am not clear about how to use MOV to transfer an immediate number into a register. From both the ARM reference manual and my textbook, it's said that range of immediate number following MOV instruction is 0-255. But when I test on my own PC in ADS 1.2 IDE, instruction MOV R2, #0xFFFFFFFF performs well. Isn't number 0xFFFFFFFF out of range according to the specification? Hope someone can give me a hand. Regards.

• How to store or share live data between PHP Requests?

  - by Devyn

  Hi, I want to start a project for facebook and the application will be like real-time multiplayer chess game. The problem I'm having is I have no idea how to store the data when a player moves one piece and update the new position in player2 browser. I'm gonna use PHP, MySQL for server side and jQuery for Client Rendering. The simplest idea is to store the data in XML or MySQL and re-generate the result to player2 browser. But I know that when thousand of players are playing, it will not be an efficient way. Since I don't have time to study new language for this project, I'm gonna have to stick with PHP. I'm not going to use flash either because I want my client side light-weight and flash-free. So is there any way that will solve my problems?

• Evaluating a function at a particular value in parallel

  - by Gaurav Kalra

  Hi. The question may seem vague, but let me explain it. Suppose we have a function f(x,y,z ....) and we need to find its value at the point (x1,y1,z1 .....). The most trivial approach is to just replace (x,y,z ...) with (x1,y1,z1 .....). Now suppose that the function is taking a lot of time in evaluation and I want to parallelize the algorithm to evaluate it. Obviously it will depend on the nature of function, too. So my question is: what are the constraints that I have to look for while "thinking" to parallelize f(x,y,z...)? If possible, please share links to study.

• Using Website Information Without WebView

  - by Mr. Monkey

  I am very new to this, and I more looking for what information I need to study to be able to accomplish this. What I want to do is use my GUI I have built for my app, but pull the information from a website. If I have a website that looks like this: (Sorry, can't post pics yet) http:// dl.dropbox.com/u/7037695/ErrorCodeApp/FromWebsite.PNG (full website can be seen at http://www.atmequipment.com/Error-Codes) What would I need from the website so that if a user entered an error code here: http:// dl.dropbox.com/u/7037695/ErrorCodeApp/InApp.PNG It would use the search from the website, and populate the error description in my app? I know this is a huge question, I'm just looking for what is actually needed to accomplish this, and then I can start researching from there. -- Or is it even possible?

• issue about Concept of JFrame, JLabel and ContentPane

  - by Sun Hong Kim

  I just study window programming with awt. I see through several codes but I can not get concepts of JFrame, JLabel and ContentPane. I think JFrame only make outer Frame. ContentPane is container that contain JLabel that has contents(text, button, radio etc...). I don't know this is correct T.T Why I ask this is I failed combine the contents. I can not make TextField and InternalFrame at a time. I want to know the concept. I hope you take my question right.

• Recommend an algorithms exercise book?

  - by Parappa

  I have a little book called Problems on Algorithms by Ian Parberry which is chock full of exercises related to the study of algorithms. Can anybody recommend similar books? What I am not looking for are recommendations of good books related to algorithms or the theory of computation. Introduction to Algorithms is a good one, and of course there's the Knuth stuff. Ideally I want to know of any books that are light on instructional material and heavy on sample problems. In a nutshell, exercise books. Preferably dedicated to algorithms rather than general logic or other math problems. By the way, the Parberry book does not seem to be in print, but it is available as a PDF dowload.

• Upload files with java

  - by Marius

  I'd like to upload a few files to a http server. Basically what i need is some sort of a post request to the server with a few parameters and the files. I've seen examples of just uploading files, but didn't find how to also pass additional parameters. So the question would be what's the simplest and free solution of doing this? Does anyone have any file upload examples that i could study? I've been googling for a few hours, but (maybe it's just one of those days) couldn't find exactly what i needed. The best solution would be something that doesn't involve any third party classes or libraries. Thank you

• What is more interesting or powerful: Curry/Mercury/Lambda-Prolog/your suggestion.

  - by Bubba88

  Hi! I would like to ask you about what formal system could be more interesting to implement from scratch/reverse engineer. I've looked through some existing and rather open (open in the sense of free/open-source) projects of logical/declarative programming systems. I've decided to make up something similar in my free time, or at least to catch the general idea of implementation. It would be great if some of these systems would provide most of the expressive power and conciseness of modern academic investigations in logic and it's relation with computational models. What would you recommend to study at least at the conceptual level? For example, Lambda-Prolog is interesting particularly because it allows for higher order relations, but AFAIK (I might really be mistaken :)) is based on intuitionist logic and therefore lack the excluded-middle principle; that's generally a disatvantage for me.. I would also welcome any suggestions about modern logical programming systems which are less popular but more expressive/powerful. I guess, this question will need refactoring, but thank you in advance! :)

• Tutorials/Books on using Mono to develop RESTful webservices?

  - by max

  Hi, anyone out there got any pointers to good links/tutorials/books on developing webservices with Mono? In more detail, I am interested in using Mono from project start on a Linux host developing in C# using Visual Studio for development, ideally with remote debugging if that is realistic developing web-services in MONO accessible in a RESTful manner, returning JSON hiding the services processes behind an Apache access the services either via javascript/AJAX or from a thin script layer written in PHP scalability is important for me unit-testing of webservices Any recommendations for material I could sift through to get a good head-start? I might add that I'm C#/.NET savvy, but not in the context of web development. I've been using it since it came out, but mainly for internal server-client applications where the clients were Windows desktop apps and the communication layer was remoting or, sometimes, more low-level socket-based. Thanks, max

• Preserve data in .net mvc

  - by Wei Ma

  I am implementing a search module with result page support paging. The example provided by NerdDinner passes pagenumber as a parameter for the Index action, and the action uses the pagenumber to perform a query each time the user hit a different page number. My problem is that my search take many more criteria such as price, material, model number etc. than just simple pagenumber. Therefore, I would like to preserve the criteria after users' first submission, so that I only have to pass the pagenumber back and forth. Using ViewData is not possible because ViewData get cleared once it is sent to the View. Is there any good way to preserve the criteria data as I wish?

• Connection to DB2 in Python

  - by Mestika

  Hi, I'm trying to create a database connection in a python script to my DB2 database. When the connection is done I've to run some different SQL statements. I googled the problem and has read the ibm_db API (http://code.google.com/p/ibm-db/wiki/APIs) but just can't seem to get it right. Here is what I got so far: import sys import getopt import timeit import multiprocessing import random import os import re import ibm_db import time from string import maketrans query_str = None conn = ibm_db.pconnect("dsn=write","usrname","secret") query_stmt = ibm_db.prepare(conn, query_str) ibm_db.execute(query_stmt, "SELECT COUNT(*) FROM accounts") result = ibm_db.fetch_assoc() print result status = ibm_db.close(conn) but I get an error. I really tried everything (or, not everything but pretty damn close) and I can't get it to work. I just need to make a automatic test python script that can test different queries with different indexes and so on and for that I need to create and remove indexes a long the way. Hope someone has a solutions or maybe knows about some example codes out there I can download and study. Thanks Mestika

• Linq2Sql Best Practices

  - by this. __curious_geek

  I'm recently migrating to Linq2Sql and all my future projects will be using Linq2Sql. Having said that, I researched a lot on how to properly plug-in Linq2Sql in application design. what to put at what layer ? How do you design your repositories and business layer services ? Should I use DTOs over Linq2Sql entities on interaction layer ? what things should I be careful about ? what problems did you face ? I did not find any rock-solid material that really talked about one single thing and everyone have their own opinions. I'm looking forward to your ideas on how to integrate/use Linq2Sql in projects. My priority is maintenance[it should be maintenable and when multiple people work on same project] and scalabilty [it should have scope of evolution]. Thanks.

• java tool for debugging

  - by user269723

  Hi experts, Currently we are studying the java based tool which is primararily Reporting tool.It was developed in 2000/2001 period and uses many open source libraries like Apache Avalon/Mx4J.Adaptor/edu.Oswego(java concurrent package) etc. Tool uses jdk 1.3.1 and goal is to upgrade to jdk 1.5.We have also been asked to remove these 'outdated' packages and replace by standard java packages if possible. Unfortunately we have the code available for study but lacks any documentation and really difficult to track the flow(Total number of classes written might be more than 1000) during debugging. Whats the best way to understand this kind of tool? any Graphical tool to see the relationship between the classes? Thanks SR

• Where can I take an online programming aptitude test/exam?

  - by nbolton

  A potential employer requires me to take an online aptitude test before my interview (in this case the test is for C, from Previsor). Where can I take the same (or similar) test so I have a rough idea on what I should brush up on? I've taken a similar test for C++ previously, so I have some idea of what to expect. I've also been studying my C books thoroughly (especially the required material as described in the PDF), but I feel it would be a good idea to get a feel for the particular test before taking it. I did a quick search on Brainbench, but they don't seem to have a C test, unless I'm mistaken (only C++). Note: I'm happy to pay to take a test if no decent free ones are available.
