• Sharing config settings between 2 cocoa apps

  - by bitboxer

  I am new to cocoa development and want to create a little app. For that app I need a background worker that is running all the time and a prefpane-app that gives the user the opportunity to change the settings for that background worker. The gui for the prefpane is ready, the background worker is ready, too. One of the few missing things is how to share the preferences between both apps. How do I notify the worker about changes of the preferences? And how do I store it in a way that both can read/write to it?

• Can't select database table even though the code is right

  - by Lisa

  I am trying to display a list of my vbulliten threads on a non-vbulliten portion of my site. However I can't select the vbulliten database: <?php $host = "localhost"; $user = "my username"; $pass = "my password"; $dbname = "tableprefix_forum"; mysql_connect($host, $user, $pass) or die ("Could not connect to database server."); mysql_select_db($dbname) or die ("Could not select database."); ?> I am substituting some things here in this example but all my credentials are correct including my db server username, password and forum db name. So what is the problem? Is it due to some internal security feature in vbulliten, does this system not allow you to connect to it's db if the page trying to connect to it is a non-vbulliten page?

• .save puts NULL in user_id field in Ruby on Rails

  - by mathee

  Here's the model file: class ProfileTag < ActiveRecord::Base def self.create_or_update(options = {}) id = options.delete(:id) record = find_by_id(id) || new record.id = id record.attributes = options puts "record.profile_id is" puts record.profile_id record.save! record end end This gives me the correct print out in my log. But it also says that there's a call to UPDATE that sets profile_id to NULL. I'm not sure I understand why the INSERT puts the value into profile_id properly, but then it sets it to NULL on an UPDATE. If you need more specifics, please let me know. I'm thinking that the save functionality does many things other than INSERTs into the database, but I don't know what I need to specify so that it will properly set profile_id.

• How to get information about a Windows executable (.exe) using C++

  - by ereOn

  Hi, I have to create a software that will scan several directories and extracts information about the executables found. I need to do two things: Determine if a given file is an executable (.exe, .dll, and so on) - Checking the extension is probably not good enough. Get the information about this executable (the company name, the product name, and so on). I never did this before and thus am not aware if there is a Windows API (or lightweight C/C++ library) to do that or if it is even possible. I guess it is, because explorer.exe does it. Do you guys know anything that could point me in the right direction ? Thank you very much for your help.

• Projects to learn Python

  - by Andrew

  I know this isn't a question about a specific snippet of code or anything, but here goes - I've been messing around with the idea of learning Python since I'm pretty bored with PHP (and web development in general), but I can't think of any projects to help me learn. I've already worked through some of Project Euler with Python, but it's getting old. I know the basics, and I want to write something more fun that will introduce me to new things in Python. Is there a cliche beginner project for Python? (for example, PHP's would be a blog or something similiar) Are there any common Python projects for newcomers, or any uncommon ones that you'd suggest? Any ideas would help.

• Interview Question: What are the characteristics of a good programmer?

  - by froadie

  I was asked this question on an interview a few months ago - "What would you say are the characteristics of a good programmer?" What would you answer to this? What, as a hiring manager, would you be looking for in an answer? I did get the job and am currently working with this company, although I don't know if that means I answered what they wanted to hear, but here were a couple of the points I mentioned: Passion PATIENCE Logic Teamwork etc. I'm especially curious to hear from the hiring side of things what would impress as an answer...

• Design pattern for data entry forms with LINQ2SQL

  - by petebob796

  I am about to start a new winforms data entry application, it already has the database designed which I am comfortable with. I was going to use LINQ2SQL to access the tables to keep things type safe but am now wondering about design patterns, something I am just getting into. Since LINQ is giving me objects to use should I still create classes in between to hold the validation code and helper methods or should these just go in with the UI? It just seems I will end up with classes sat in between with little code which will cause the UI classes to have code just getting and setting values in the intermediate class and returning from validation to flag errors... Any good reading on this? Should I consider the entity framework (or similar) instead?

• What features of Scala cannot be translated to Java?

  - by Paul

  The Scala compiler compiles direct to Java byte code (or .NET CIL). Some of the features of Scala could be re-done in Java straightforwardly (e.g. simple for comprehensions, classes, translating anonymous/inner functionc etc). What are the features that cannot be translated that way? That is presumably mostly of academic interest. More usefully, perhaps, what are the key features or idioms of Scala that YOU use that cannot be easily represented in Java? Are there any the other way about? Things that can be done straightforwardly in Java that have no straightforward equivalent in Scala? Idioms in Java that don't translate?

• How should I store Dynamically Changing Data into Server Cache?

  - by Scott

  Hey all, EDIT: Purpose of this Website: Its called Utopiapimp.com. It is a third party utility for a game called utopia-game.com. The site currently has over 12k users to it an I run the site. The game is fully text based and will always remain that. Users copy and paste full pages of text from the game and paste the copied information into my site. I run a series of regular expressions against the pasted data and break it down. I then insert anywhere from 5 values to over 30 values into the DB based on that one paste. I then take those values and run queries against them to display the information back in a VERY simple and easy to understand way. The game is team based and each team has 25 users to it. So each team is a group and each row is ONE users information. The users can update all 25 rows or just one row at a time. I require storing things into cache because the site is very slow doing over 1,000 queries almost every minute. So here is the deal. Imagine I have an excel spreadsheet with 100 columns and 5000 rows. Each row has two unique identifiers. One for the row it self and one to group together 25 rows a piece. There are about 10 columns in the row that will almost never change and the other 90 columns will always be changing. We can say some will even change in a matter of seconds depending on how fast the row is updated. Rows can also be added and deleted from the group, but not from the database. The rows are taken from about 4 queries from the database to show the most recent and updated data from the database. So every time something in the database is updated, I would also like the row to be updated. If a row or a group has not been updated in 12 or so hours, it will be taken out of Cache. Once the user calls the group again via the DB queries. They will be placed into Cache. The above is what I would like. That is the wish. In Reality, I still have all the rows, but the way I store them in Cache is currently broken. I store each row in a class and the class is stored in the Server Cache via a HUGE list. When I go to update/Delete/Insert items in the list or rows, most the time it works, but sometimes it throws errors because the cache has changed. I want to be able to lock down the cache like the database throws a lock on a row more or less. I have DateTime stamps to remove things after 12 hours, but this almost always breaks because other users are updating the same 25 rows in the group or just the cache has changed. This is an example of how I add items to Cache, this one shows I only pull the 10 or so columns that very rarely change. This example all removes rows not updated after 12 hours: DateTime dt = DateTime.UtcNow; if (HttpContext.Current.Cache["GetRows"] != null) { List<RowIdentifiers> pis = (List<RowIdentifiers>)HttpContext.Current.Cache["GetRows"]; var ch = (from xx in pis where xx.groupID == groupID where xx.rowID== rowID select xx).ToList(); if (ch.Count() == 0) { var ck = GetInGroupNotCached(rowID, groupID, dt); //Pulling the group from the DB for (int i = 0; i < ck.Count(); i++) pis.Add(ck[i]); pis.RemoveAll((x) => x.updateDateTime < dt.AddHours(-12)); HttpContext.Current.Cache["GetRows"] = pis; return ck; } else return ch; } else { var pis = GetInGroupNotCached(rowID, groupID, dt);//Pulling the group from the DB HttpContext.Current.Cache["GetRows"] = pis; return pis; } On the last point, I remove items from the cache, so the cache doesn't actually get huge. To re-post the question, Whats a better way of doing this? Maybe and how to put locks on the cache? Can I get better than this? I just want it to stop breaking when removing or adding rows.

• How to bundle C code in C shell script?

  - by eSKay

  I have a C shell script that calls two C programs - one after the another with some file handling before, in-between and afterwards. Now, as such I have three different files - one C shell script and 2 .c files. I need to give this script to other users. The problem is that I have to distribute three files - which the users must keep in the same folder and then execute the script. Is there some better way to do this? [I know I can make one C code file out of those two... but I will still be left with a shell script and a C code. Actually, the two C codes do entirely different things... so I want them to be separate]

• Modify bash variables with sed

  - by Alexander Cska

  I am trying to modify a number of environmental variables containing predefined compiler flags. To do so, I tried using a bash loop that goes over all environmental variables listed with "env". for i in $(env | grep ipo | awk 'BEGIN {FS="="} ; { print $1 } ' ) do echo $(sed -e "s/-ipo/ / ; s/-axAVX/ /" <<< $i) done This is not working since the loop variable $i contains just the name of the environmental variable stored as a character string. I tried searching a method to convert a string into a variable but things started becoming unnecessary complicated. The basic problem is how to properly supply the environmental variable itself to sed. Any ideas how to properly modify my script are welcome. Thanks, Alex

• Dynamic Dropdown menu through php

  - by Code_Ed_Student

  I visited a website a few weeks ago and came across a dynamic drop down menu. I came across a functionality that I am now trying to replicate but do not know how. In the dropdown you picked the desired number of cars and then it reiterated input fields according to the number of cars chosen. I believe this was done through javascript and a loop was involved. Is there a term for this action or way to display things? Also an example of how to accomplish something similar would help?

• Need Insight - What is the best practice for syncing up a production database that will be used on a

  - by james

  I have a site set up using CakePHP and MySQL and I want to work on a test database without disrupting my live site in case something goes wrong. I have another busy site, but my test site runs off the live database which can be occasionally nerve wracking. What do I do if I change a table name in the test db and I want it changed in the live database? Or if I remove a record from the test database. Is there a way to diff the changes? How do I even merge those changes? How does this interfere with live user edits and things of that nature? Hopefully some of you working devs can share some insight!

• How can one change the primary key using NHibernate.

  - by mark

  Dear ladies and sirs. I want to change the primary key of an entity in database, so that all the relevant foreign key constraints are updated as well./We are using NHibenate as our ORM. Is it possible to do it? Thanks. P.S. I know the practice of changing the primary key is highly discouraged. My problem is that my primary key is backed by a natural Id of the entity, which may sometimes change. We could, theoretically, utilize a unique primary key, unrelated to the natural key of the entity, but this complicates things too much in other places, so this is not an option.

• Getting started with a facebook application

  - by Cyclone

  I'm really new to Facebook application development, and I'm quite confused about application permissions and why the php sdk is so limiting and has so few precoded functions. First off, how do I check if a user has set proper permissions for my application, and if not, display that standard dialog immediately instead of using FBML and making them click the link? Secondly, how do I publish to a user's stream with the php apis? Finally, are there any good tutorial sites for making a php based canvas application that use the latest versions of all the sdks? Thank you for your help! I really don't see why so much of this is Javascript, it would really make much more sense to me to have things like: if(!$facebook->appHasPerm('publish_stream'){$facebook->showPermDialog('publish_stream');} I'd feel like I have much more control over the application if it worked like that.

• How to share common css and other resources among grails projects?

  - by Troy

  I'm working on a grails-based web application that will be composed of a couple of different grails projects, each developed by a separate team, which will eventually all be unified under a common "portal." So they need to have the same look and feel, at least to some degree. Is there a "blessed" way to share resources like this among projects? Something using the grails plugin architecture maybe? Would it make sense to just create a separate lightweight project containing nothing but the css and any shared resources? How have the rest of you handled sharing things between different grails projects?

• Detect at runtime which country's App Store my iPhone app was downloaded from?

  - by Mike McMaster

  I have a feature in my iPhone application that, for business reasons, should only be shown/available to customers in the US. If I want to release this app to App Stores outside the US, what's the best way to figure out which country I'm in without relying on user-defined settings such as language and locale? In my mind, the ideal solution is that there's some runtime property that can tell me which App Store country the app was downloaded from, and I can take action accordingly. Looking through the docs and searching the web, I'm not coming up with anything in this department. I don't expect the solution to be 100% foolproof as far as users not being in the country they say they're from, but as close as possible would be nice. I suppose one solution would be to make a separate build for a new product on the App Store and have two versions, one for the US and one for the others, but that doesn't seem ideal. I'm hoping it can be the same product on the App Store to prevent things like fragmentation of user reviews. Thanks in advance!

• scala xml rewrite rule (or, simple pattern help)

  - by williamstw

  I'm missing some fairly simple syntax I gather. I'm trying to rewrite an element label to something else and keep everything else intact. object htmlRule extends RewriteRule { override def transform(n: Node): Seq[Node] = n match { case Elem(prefix, "document", attribs, scope, child@_*) => Elem(prefix, "html", attribs, scope, child) case other => other } } Now, I ask for an explanation of two things: 1) What exactly does "child@_*" mean in plain English? 2) How can I capture the value of "child@_*" and just let it pass right through to the new element? Currently, I get the following error, which makes sense. [error] found : Seq[scala.xml.Node] [error] required: scala.xml.Node [error] Elem(prefix, "html", attribs, scope, child) I'm not wedded to this either, so if there's a better way to simply change the element name of a specific node, let's here it... Thanks, --tim

• If you select an element in jQuery by ID is there still a speed improvement by giving it a parent to

  Imagine this simplified markup: <div id="header"> <!-- Other things.... --> <div id="detail"> </div> </div> and assume you already have this code: var $hdr = $("#header"); Is there any speed difference for jQuery to lookup "detail" this way: var $detail = $("#detail", $hdr); vs var $detail = $("#detail"); Since detail is being looked up by ID?

• How do I create "undo" in c++?

  - by b3y4z1d

  I've got a couple of codes to do some things but I need to create a function that undoes the previous task/addition/change.How do I do this in Borland C++? (the program stores strings of text in a text file using "list",it is stored and then erased unless I use the save-function I've created) right,so I don't know if I've forgotten to mention anything of importance for you to be able to help me better,but if there's something you're wondering about the functions just ask. I meant creating an undo function in a simple consol application by the way.

• Including Libraries C++

  - by m00st

  How do I properly include libraries in C++? I'm used to doing the standard libraries in C++ and my own .h files. I'm trying to include wxWidgets or GTK+ in code::blocks and/or netbeans C/C++ plugin. I've included ALL libraries but I constantly get errors such as file not found when it is explicitly in the include! One error: test1.cpp:1:24: wx/msw/wx.rc: No such file or directory : Yes the .h file library is included; what am I missing? Do I need to be importing other things as well? Is there a tutorial for this? Obviously my shoddy textbook hasn't prepared me for this.

• How do I select an option using Spring's form:select tag?

  I'm using Spring 3.1.1.RELEASE. Using the form:select tag, how do I specify which option should be selected? I want the first one to be selected, but when I put <form:select path="parentOrganization"> <form:option value="" label="Select an Org Type or Parent Org" /> <form:options items="${orgTypesWoParents}" itemValue="id" itemLabel="description" /> <form:option value="" label="=======================" /> </form:select> the last one is selected. I want to preserve the order of how everything is displayed, which is why I've arranged things in this way.

• How to check for C++ copy ellision

  - by Steve

  I ran across this article on copy ellision in C++ and I've seen comments about it in the boost library. This is appealing, as I prefer my functions to look like verylargereturntype DoSomething(...) rather than void DoSomething(..., verylargereturntype& retval) So, I have two questions about this Google has virtually no documentation on this at all, how real is this? How can I check that this optimization is actually occuring? I assume it involves looking at the assembly, but lets just say that isn't my strong suit. If anyone can give a very basic example as to what successful ellision looks like, that would be very useful I won't be using copy ellision just to prettify things, but if I can be guaranteed that it works, it sounds pretty useful.

• Accessing 'data' argument of with() function?

  - by Ken Williams

  Is it possible, in the expr expression of the with() function, to access the data argument directly? Here's what I mean conceptually: > print(df) result qid f1 f2 f3 -1 1 0.0000 0.1253 0.0000 -1 1 0.0098 0.0000 0.0000 1 1 0.0000 0.0000 0.1941 -1 2 0.0000 0.2863 0.0948 1 2 0.0000 0.0000 0.0000 1 2 0.0000 0.7282 0.9087 > with(df, subset(.data, select=f1:f3)) # Doesn't work Of course the above example is kind of silly, but it would be handy for things like this: with(subset(df, f2>0), foo(qid, vars=subset(.data, select=f1:f3))) I tried to poke around with environment() and parent.frame() etc., but didn't come up with anything that worked. Maybe this is really a question about eval(), since that's how with.default() is implemented.

• What did they program this toy with?

  - by Trix

  A rather strange question: I'm often asking myself with what programming languages things were created. I recently found this toy mini computer I played with when I was 13 or so at home. (Note: It is not one of those toy "notebooks", it's really small and came as an extra with a magazine) "Features": Hadware: LCD with a small field of pixels where the games were going on, besides that some stats such as score, highscore etc. Sounds and horrible music when started A really small "keyboard" with a wire Software: At least 14 or so games, from Snake over Tetris and Breakdown to some abomination of a car racing game A calculator Game selecting menu An alarm clock Inside there is a really small circuit board, I don't want to open the thing up now, though. Can you imagine if the games and "Operating System" of this thing where actually programmed using a language? If yes, what language could it be? If not with a programming language, how else was it created?
