• Breaking out of .emacs script

  - by prosseek

  I use two emacs (Aquamcs and text based emacs) on my Mac. I normally use text based emacs for just editing something, so I don't want to load anything with it. What I came up with is to have the checking code in .emacs to exit/break if it's text based emacs (darwin system but not aquamacs). (when (and (equal system-type 'darwin) (not (boundp 'aquamacs-version))) (exit) ??? (break) ???? ) It seems to work, but I don't know how to break out of .emacs. How to do that? ADDED I just wanted to speed up in loading text based emacs on my mac, and I thought about breaking out as a solution. Based on the helpful answers, I came up with the following code that runs .emacs only when it's not a text based emacs. (setq inhibit-splash-screen t) (unless (null window-system)

• Is there a ways to make google store coordinates in the android map?

  - by Pavel

  Hi. I'm in the middle of developing android app using google map. My question is - how to store coordinates with google map and display them later on?

When I log in I can see points I've put on the map straight away. Can someone please tell me how to do that? There must be a way. Any answers greatly appreciated!

• MySQL: Selecting One Record When Others Have Same Data

  - by LoganFrederick

  I have a table of cities that all share the same area code: 367 01451 Harvard Worcester Massachusetts MA 978 Eastern 368 01452 Hubbardston Worcester Massachusetts MA 978 Eastern 369 01453 Leominster Worcester Massachusetts MA 978 Eastern The table has multiple area codes, all with multiple cities. What I'd like to do is only select one city from each area code and delete any extra cities from duplicate area codes. What would be the best query to accomplish this? I believe: http://stackoverflow.com/questions/596629/mysql4-sql-for-selecting-one-or-zero-record Is coming close to what I need but didn't quite get what/how those answers were working. Note The "978" row is the "area_code" row, table name is "zip_code".

• An elegant / simple way to check whether internet is available or not.

  - by Trainee4Life

  I did a quick search on how to check whether Internet is available or not. Most of them talked about making InterOp calls to wininet.dll. One of the answers pointed towards System.Net.NetworkInformation namespace. Exploring the namespace I found a class Ping which could be used to pinging to our servers from code, and checking whether server is available or not. What I want to ask is how this solution compares to other solutions? Ping soPing = new Ping(); var soPingReply = soPing.Send("www.stackoverflow.com"); if (soPingReply.Status != IPStatus.Success) { // SO not available }

• iPhone SDK: How do I programatically change the background image of a UIButton added to a NIB?

  - by user304583

  I've seen several questions/answers related to entirely creating a button in code, but not one which would let me know how to change the button image in code, when I originally added the button to my NIB in Interface Builder. I know how to change the background in Interface Builder.. but I want to change it in code, so I can change it automagically. Any help really appreciated! Perhaps the answer is so obvious nobody needs to ask.. if so please forgive the dweeb that I am and help! :-)

• C# Spawn Multiple Threads for work then wait until all finished

  - by pharoc

  just want some advice on "best practice" regarding multi-threading tasks. as an example, we have a C# application that upon startup reads data from various "type" table in our database and stores the information in a collection which we pass around the application. this prevents us from hitting the database each time this information is required. at the moment the application is reading data from 10 tables synchronously. i would really like to have the application read from each table in a different thread all running in parallel. the application would wait for all the threads to complete before continuing with the startup of the application. i have looked into BackGroundWorker but just want some advice on accomplishing the above. Does the method sound logical in order to speed up the startup time of our application How can we best handle all the threads keeping in mind that each thread's work is independent of one another, we just need to wait for all the threads to complete before continuing. i look forward to some answers

• How can I use a carriage return in a HTML tooltip ?

  - by ip

  Hi, I'm currently adding verbose tooltips to our site, and I'd like (without having to resort to a whizz-bang jQuery plugin, I klnow there are many!) to use carriage returns to format the tooltip. To add the tip I'm using the 'title' attribute. I've looked around the usual sites and using the basic template of: <a title='Tool?Tip?On?New?Line' >link with tip</a> I've tried replacing the '?' with: <br /> &013; / &#13; \r\n Environment.NewLine (I'm using C#) Neither work. Is it possible ?? WOW! Thanks all - 6 different answers in less than an hour. Thanks indeed!!

• Require help with program for edutainment game

  - by Ender

  I am working on a factorisation problem and for small numbers it is working well. I've been able to calculate the factors (getting the answers from Wolfram Alpha) for small numbers, like the one on the Wikipedia page (5959). Along with the Wikipedia page I have been following this guide. Once again, as my Math knowledge is pretty poor I cannot follow what I need to do next. EDIT: It finally works! I'll post the working code up here once I've got it fully working so that others in my predicament can learn from it.

• Bitmap manipulation as a referenced object

  - by John Maloney

  I am working with a Bitmap object that I add annotations or copyright material to the image and then return the modified bitmap. My problem is that the Bitmap won't hold the changes made to it as it moves along the chain. I am treating it as a reference type and would assume that as it gets passed to each class it would carry the changes made to it. I have verified that the code inside of the MarkImage() classes does function, but which ever one gets called last is the one that has changes. Public Shared Function GetImage(ByVal imageDef As IImageDefinition) As Bitmap Dim image As Bitmap = Drawing.Image.FromFile(imageDef.Path) If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutCopyright) Then image = New MarkCopyrightImage(image).MarkImage() End If If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutAnnotations) Then image = New MarkAnnotateImage(image).MarkImage() End If Return image End Function How do I write changes to a bitmap object and then pass that object to another class while maintaining the changes? Answers in C# or VB are fine? Thanks

• overiding to_param of a nested attribute

  - by cbrulak

  I'm trying to create a perma link for a nested attribute. For example, look at the links for the answers in SO. I would like to do something similar in rails: I have Project model with multiple tasks and I would like to create a perma link to a task. The task can only viewed with the project, just like Q & A on SO. Ideally, i would do something like: task_helper.rb: def GetTaskURL project = Project.find(:project_id) return project_url(project,:html) + "#" + id end However, i get a method not found. So it seems the only way is to hard-code it: domain.com url + Projects/show/id.html#task.id Must be a better way?

• Actionscript 3.0 cross-project folder/package structure best practise

  - by dr_tchock

  I'm currently looking at structuring my teams projects into a consistent manner that properly utilises packages and is easily version-controlled (via SVN). I'm interested in any 'best practise' with regards to project structuring and how to use consistent packaging without lumping everything into a gigantic com.domainname.projects folder structure whilst maintaining that package structure. I'm also keen to use the src/bin/lib folder structure within each project. I guess I'm asking 'how do you do it?' and 'why?'. Sorry if this is a bit abstract for Stack Overflow but you guys give the best answers I've found.

• Any valid use of goto in PHP?

  - by nikic

  I know, there are other questions about the goto statement introduced in PHP 5.3. But I couldn't find any decent answer in there, all were of the type "last resort", "xkcd", "evil", "bad", "EVIL!!!". But no valid example. Only statements that there aren't any uses. Or statements that there are some rare use cases (again, without examples). So, the question is: "Which are the valid uses of goto in PHP". Answers for "Is goto evil" are not welcome and will get downvoted. Thanks :) Or does somebody have a link to an RFC where the decision is explained - I couldn't find one.

• Which are the current/emerging desktop development technologies worth looking into?

  - by heeboir

  Greetings, With all the existing development towards web development and emerging technologies in that area, I'm left wondering; what is a state of the art way to implement desktop applications in this day and age? If you were to start a new application of considerable size from scratch what technology would you invest your efforts in (focusing on cross platform portability, decent performance and interoperability with existing standards)? I've looked into the Adobe Air platform which appears quite impressive but seems rather limited to support a large application. Would something like Java/SWT still be the sensible choice? Do things like GWT fit the bill? Thanks P.S. I'm leaving my question a bit open-ended in an effort to gather diverse answers. Surely this a subjective matter and there is no right and wrong answer.

• C++ DWORD* to BYTE*

  - by NomeSkavinski

  My issue, i am trying to convert and array of dynamic memory of type DWORD to a BYTE. Fair enough i can for loop through this and convert the DWORD into a BYTE per entry. But is their a faster way to do this? to take a pointer to DWORD data and convert the whole piece of data into a pointer to BYTE data? such as using a memcpy operation? I feel this is not possible, im not requesting an answer just an experienced opinion on my approach, as i have tried testing both approaches but seem to fail getting to a solution on my second solution. Thanks for any input, again no answers just a point in the right direction. Nor is this a homework question, i felt that had to be mentioned.

• Preparing for the next C++ standard

  - by Neil Butterworth

  The spate of questions regarding BOOST_FOREACH prompts me to ask users of the Boost library what (if anything) they are doing to prepare their code for portability to the proposed new C++ standard (aka C++0x). For example, do you write code like this if you use shared_ptr: #ifdef CPPOX #include <memory> #else #include "boost/shared_ptr.hpp" #endif There is also the namespace issue - in the future, shared_ptr will be part of the std, namespace - how do you deal with that? I'm interested in these questions because I've decided to bite the bullet and start learning boost seriously, and I'd like to use best practices in my code. Not exactly a flood of answers - does this mean it's a non-issue? Anyway, thanks to those that replied; I'm accepting jalfs answer because I like being advised to do nothing!

• OSError: [Error 1] Operation not permitted

  - by user1357576

  I am trying to run a python script which uses a binary file (xFiles.bin.addr_patched) created by a postlinker. However, I am getting this error. File "abc.py", line 74, in ParseCmd shutil.copy(gOptions.inputX, gWorkingXFile) File "/usr/lib/python2.6/shutil.py", line 89, in copy copymode(src, dst) File "/usr/lib/python2.6/shutil.py", line 66, in copymode os.chmod(dst, mode) OSError: [Errno 1] Operation not permitted: 'myPath/xFiles.bin.addr_patched' When I checked the permissions of this xFiles.bin, by ls-l, it shows that -rwxrwxrwx 1 nobody nogroup I presume the error is because this file was created by some other application, the python script I am running does not have access to it. Since I am beginner wrt ubuntu, I don't really know how to fix it. Any suggestions on how to fix this? SOLVED: As one of the answers Suggested : chown username:groupname file name fixes this issue

• IE 8 and text fading

  - by DMIL

  I have a problem with fading text in IE 8, 7 and 6 (obviously). The text has a black outline during the animation that completely ruins the effect. Is there a workaround? I've read a bunch of answers about this problem and none made sense. Please take a look at this simple jsFiddle http://jsfiddle.net/LhSK7/ in IE 8, and show me how to fix it if possible. Edit: screenshot of the problem: http://i43.tinypic.com/1z6h1th.png I thought it might be because of the VirtualBox, but all other browsers display it correctly in VirtualBox. Edit #2: the problem can sort of be solved by setting the background color of the element being faded, which while still pretty ugly in IE 8 and below, at least gets rid of the black outline.

• Handling the distinction between undefined- and null-parameters in JavaScript

  - by Jakob

  I know very well that null and undefined are distinct in JavaScript. However, I can't seem to decide whether or not use that fact when my own functions are passed one of those as its argument. Or, expressed in a different way, should myFoo(undefined) return the same thing as myFoo(null) or is everything fine if it doesn't? Or, in yet another case, since myBar(1, 2, 3) is the same thing as myBar(1, 2, 3, undefined, undefined), should myBar(1, 2, 3, null, null) return the same thing as myBar(1, 2, 3)? I feel that there's potential for confusion in both cases and that a library should probably follow a convention when handling null/undefined. I'm not really asking for personal opinions (so please express those as comments rather than answers). I'm asking if anyone knows if there is a best practice that one should stick to when it comes to handling this distinction. References to external sources are very welcome!

• How to transition from PHP to Python Django?

  - by ggfan

  Here's my background: Decent experience with PHP/MySql. Beginner's experience with OOP Why I want to learn Python Django? I gave in, based on many searches on SO and reading over some of the answers, Python is a great, clean, and structured language to learn. And with the framework Django, it's easier to write codes that are shorter than with PHP Questions Can i do everything in Django as in PHP? Is Django a "big" hit in web development as PHP? I know Python is a great general-purpose language but I'm focused on web development and would like to know how Django ranks in terms of web development.

• How can an SQL query return data from multiple tables

  - by Fluffeh

  I would like to know how to get data from multiple tables in my database, what types of methods are there to do this, what are joins and unions and how are they different from one another? When should I use each one compared to the others? I am planning to use this in my (for example - PHP) application, but don't want to run multiple queries against the database, what options do I have to get data from multiple tables in a single query? Note: I am writing this as I would like to be able to link to a well written guide on the numerous questions that I constantly come across in the PHP queue, so I can link to this for further detail when I post an answer. The answers cover off the following: Part 1 - Joins and Unions Part 2 - Subqueries Part 3 - Tricks and Efficient Code

• iPhone Gestures Adding 2 at once

  - by BahaiResearch.com

  Objective C answers are fine too. Currently I am using this code to add 2 gestures (left / right) to my WebView. Works fine. Can I combine this into less code though to indicate that both gestures go to the same action? //LEFT UISwipeGestureRecognizer sgr = new UISwipeGestureRecognizer (); sgr.AddTarget (this, MainViewController.MySelector); sgr.Direction = UISwipeGestureRecognizerDirection.Left; sgr.Delegate = new SwipeRecognizerDelegate (); this.View.AddGestureRecognizer (sgr); //RIGHT UISwipeGestureRecognizer sgrRight = new UISwipeGestureRecognizer (); sgrRight.AddTarget (this, MainViewController.MySelector); sgrRight.Direction = UISwipeGestureRecognizerDirection.Right; sgrRight.Delegate = new SwipeRecognizerDelegate (); this.View.AddGestureRecognizer (sgrRight);

• SQL query help - merge a value to all rows in a column

  - by Tommy

  I'm trying to migrate a site from a joomla system to a drupal. The problem is that drupal needs filename and sourcepath in the same row, but joomla only has filename. I'm looking for a way to add sourcepath before the filename in all the rows in that column. I'm figuring it's the UPDATE statement that I should use, but I can't figure out how to construct the query. There's a person with a similar problem here, but I don't find the answers in that thread helpful to my problem: http://www.daniweb.com/forums/showth...t+value&page=2 Any suggestions?

• SSRS 2008: How to do multiple values report?

  - by Shimrod

  Hi everyone, Right now I have an application which uses Reporting Services to render reports. This is working nicely, I call each report with a given value (e.g. a ClientId), and the report gets rendered correctly. However, what I'd like to do now is being able to send multiple ClientIDs to the report, and would like to get 1 pdf file with count(ClientsIDs) pages, each containing the report, according to the ClienID. How is that possible? I don't really know how to name what I want to do, so I don't really find answers on the net right now. Maybe someone has a tutorial for me? Thanks in advance !

• JavaScript eval() with `this`

  - by mojuba

  If I define a JavaScript code snippet in my HTML, like so: <div id=myElem onMyUpdate="alert('Update called for ' + this.id)">... then what is the most elegant way of evaluating it from within JavaScript with this properly assigned? What I came up with so far is something like this: if (elem.hasAttribute('onMyUpdate')) (function () { eval(elem.getAttribute('onMyUpdate')) }).call(elem); which looks terrible (to me), but works. Any better/more elegant alternatives? MDN says there used to be the second argument to eval() for doing just that but it's deprecated now; MDN then suggests to use operator with() instead, which, if you follow the link provided, turns out to be made deprecated by the latest standard. Dead end, in other words. (As a side note, StackOverflow ignores the word this in search terms and thus it may miss relevant answers - is there a way of telling it not to?) Edit: I forgot to mention: no jQuery please, just vanilla JavaScript
