• Suspension of Gmail account [closed]

  - by Ifeanyi Agu

  I have a Joomla site with my gmail account (google apps) being used as the SMTP server for sending mails. I also have a newsletter component on this site. I tried sending newsletter to all my subscribers and I noticed that the SMTP server could not be connected to. I then checked the emails of my company and noticed that the one I used to set it up was suspended. I cannot really explain why Google suspended the email account. Please could anyone tell me if Google saw the mails that were being sent as spam.

• What is the purpose of Process class in Java?

  - by Nitesh Panchal

  Runtime objRuntime = Runtime.getRuntime(); String strBackupString = "mysqldump -u " + userName + " -p" + password + " " + dbName; Process objProcess = objRuntime.exec(strBackupString); This is used for backup of database. But what exactly happens? Can anybody make me explain, what is the purpose of Runtime and Process class? Is this class used to act as if we are typing command from command prompt? Then what should i pass to objRuntime.exec() if i want to open notepad? And is the command executed as soon as we call exec method? If yes, then what purpose does Process serve here? I really can't understand these two classes. Please make me understand. Thanks in advance :)

• the problem of redirecting stdout in c#

  - by Mher

  Could you please explain why the shell redirection doesn't work with System.Diagnostics.Process class? I am trying to redirect the output streams to file with the following snippet: Process p = new Process(); p.StartInfo = new ProcessStartInfo(); p.StartInfo.FileName = "java.exe"; p.StartInfo.Arguments = @"> c:\Temp\test.log 2>&1"; p.StartInfo.UseShellExecute = true; p.Start(); The similar code works without problems with Python. Reading the output streams programmatically doesn't seem a preferable solution in my case because there will be a bunch of processes launched by my application.

• Counting values in data frame subject to conditions

  - by unixsnob

  I have been searching around and I cannot figure out how to sumarise the data I have in my data frame (subject to some ranges). I know that it can be done when applying some combination of daaply/taaply or table but I haven't been able to get the exact result I was expecting. Basically I want to turn this: part_no val1 val2 val3 2 1 2 3 45.3 2 1 3 4 -12.3 3 1 3 4 99.3 3 1 5 2 -3.2 3 1 4 3 -55.3 Into this: part_no val3_between0_50 val3_bw50_100 val3_bw-50_0 val3_bw-100_-50 2 1 0 0 1 0 3 0 1 0 1 1 This is dummy data, I got a lot more rows, but the idea is the same. I just want to count the number of values for a participant that meet certain condition. If anyone could explain it sort of step by step, I would really appreciate it. I saw lots of different little posts around, but none do exactly this and my attempts only got me half way there. Like using table, etc. Thanks!

• Graphics Question: How do I restrict the mouse cursor to within a circle?

  - by Dan

  I'm playing with XNA. When I click the left mouse button, I record the X,Y co-ordinates. Keeping the mouse button held down, moving the mouse draws a line from this origin to the current mouse position. I've offset this into the middle of the window. Now, what I'd like to do is restrict the mouse cursor to within a circle (with a radius of N, centred on the middle of the screen). Restricting the mouse to a rectangular region is easy enough (by adjusting the origin by the difference of the mouse position and the size of the region), but I haven't a clue on how to start doing it for a circular region. Can anyone explain how to do this? Any advice on where to start would be helpful.

• jquery plugin pattern using jquery.data

  - by web_dev

  I have seen this piece of code in jquery plugin patterns and the notes section mention that we could attach the plugin to the DOM element using the jQuery.data function. What I don't understand is how do I make use of this piece of code. Can somebody provide examples of how to use this functionality and explain its significance? $.fn[pluginName] = function (options) { return $Extend(this).each(function () { if (!$.data(this, 'plugin_' + pluginName)) { $.data(this, 'plugin_' + pluginName, new Plugin( this, options )); } }); };

• Postfix evaluation in C

  - by Andrewziac

  I’m taking a course in C and we have to make a program for the classic Postfix evaluation problem. Now, I’ve already completed this problem in java, so I know that we have to use a stack to push the numbers into, then pop them when we get an operator, I think I’m fine with all of that stuff. The problem I have been having is scanning the postfix expression in C. In java it was easier because you could use charAt and you could use the parseInt command. However, I’m not aware of any similar commands in C. So could anyone explain a method to read each value from a string in the form: 4 9 * 0 - = Where the equals is the signal of the end of the input. Any help would be greatly appreciated and thank you in advance :)

• sending data to the server via port 5555 C#

  - by numerical25

  I am wanting to send some data to a server from a client application to the server via port 5555. I don't have a window's server. My question is if I purchase a .Net Framework hosting service. Would I be able to connect the client application to this server. and could I do it by sending a Post. I am new to this, so excuse me if it doesn't entire make sense. but I am looking for just some little direction. If someone could explain what port 5555 is used for that would be great.

• IE 8 Error - What's the cause?

  - by DanCapitanDePlai

  I have two magento eshops that worked perfectly in the past on all major browsers except IE 7. After I installed WINDOWS XP on my computer and accessed my eshops with IE 8, I almost had a heartattack seeing that they aren't working as they should. Before installing Windows XP I was running Windows 7 and the websites were looking good on IE 8. Now, the same IE version, but on different operating systems, gives me headaches! Now, can someone explain me how to 'debug' the ie 8 parsing engine for seeing the errors and try to modify the templates? Thanks.

• Resetting a while loop

  - by Patrick Beardmore

  I have found a confusing thing in a php script I am writing to generate some javascript. Here it is below, slightly simplified. The second while loop won't run unless I comment out the entire first while loop. Can anyone explain why? Many thanks. <?php $listid = 2; //DEMO ONLY $result1 = mysql_query("SELECT words.wid,words.wordmd5,words.word FROM words,instances WHERE words.wid = instances.wid AND instances.lid = \"$listid\""); $result1copy = $result1; $count1 = 1; while( $row = mysql_fetch_object( $result1 ) ) { print "words_left[$count1] = \"".$row->word."\";\n"; //Increment the array counter (starts at 1) $count1++; } ?> //Some javascript <?php $count2 = 1; while( $row = mysql_fetch_object( $result1copy ) ) { print " $count2 then $row->wordmd5 "; $count2++; } ?>

• If I had to create a server farm what should I do? (how others companies work?)

  - by Michel

  I have a business idea but this is not really my field so I'm trying to understand what I'm really dealing with. I have a general understanding of how a web farm works, I'm a web developer and I understand the technology behind it, but I'm curious to know specifically how a web farm is set up and which professionals are involved. Things to consider probably are the hardware, the power supply, the software managment, the cooling system and if possible the usage of green technology/power recycling. Basically, can you explain me how a web hosting company is structured and how it works? A big question, I know, but from what I already read here about the subject a lot of you know this stuff. Thanks for your time guys!

• About memory and delete object in c++

  - by barssala

  I will give some examples and explain. First, I declare some object like CString* param = new CString[100] And when I declare this one, my memory would increase a little bit because it's some implemented string. Then I store this object in some list of CString just like List<CString> myList = new List<CString>; // new list of CString myList.add(param); This is my question: I wanna know, when I delete myList, my param isn't deleted, right? And memory in param still exists. Do I misunderstand?

• Can I use a single pointer for my hash table in C?

  - by aks

  I want to implement a hash table in the following manner: struct list { char *string; struct list *next; }; struct hash_table { int size; /* the size of the table */ struct list **table; /* the table elements */ }; Instead of struct hash_table like above, can I use: struct hash_table { int size; /* the size of the table */ struct list *table; /* the table elements */ }; That is, can I just use a single pointer instead of a double pointer for the hash table elements? If yes, please explain the difference in the way the elements will be stored in the table?

• Reading a bmp file and inverting it in C

  - by user1763396

  I have an assignment that deals with reading a bmp file into memory, inverts the pixels, and then saves the inverted image to a new file. From this description it seems fairly easy, however I don't think my professor did a great job in explaining the necessary steps to go about doing so. He taught us about fread and fwrite but there is so much more. Can anyone explain the process in going about this problem (I'm no looking for a direct answer just an explanation). Here is the link to the problem's description: https://engineering.purdue.edu/OOSD/F2012/Exercises/ex5.html Thanks in advance for any sort of help. NOTE: I actually have looked into this problem but since I don't have a good standing on this info it's not quite "clicking".

• SQL - logical AND among multiple rows

  - by potrnd

  Hello, First of all sorry that I could not think of a more descriptive title. What I want to do is the following using only SQL: I have some lists of strings, list1, list2 and list3. I have a dataset that contains two interesting columns, A and B. Column A contains a TransactionID and column B contains an ItemID. Naturally, there can be multiple rows that share the same TransactionIDs. I need to catch those transactions that have at least one item ID that exists whithin each list (list1, list2 AND list3). I also need to count how many times does that happen for each transaction. I hope that makes enough sense, perhaps I will be able to explain it better with a clear head. Thanks in advance

Can anyone explain me clearly over this.

• Problem building relationships between models

  - by Brian Roisentul

  Until now, I've been using acts_as_taggable_on plugin for tagging announcements. That plugin creates the following tables: taggings: relates tags and announcements table(for the tagged item, it has a field called taggable_id, which I rename to "announcement_id" for what I'll explain below). tags: has the tag ids and names. The other day, I discovered that I had no way of getting the announcements tagged with a certain tag, but doing Announcement.tagged_with(tag_name), and I don't want to search by name, but for id. So, as I'm using almost nothing of the functionality in that plugin, I decided to create the models for taggings and tags tables, to accomplish this: Announcement.tags. The models' relationships look as following: class Tagging < ActiveRecord::Base belongs_to :announcement belongs_to :tag end class Tag < ActiveRecord::Base has_many :announcements, :through => :taggings end class Announcement < ActiveRecord::Base has_many :tags, :through => :taggings Why can't I execute the command Announcement.tags? Because when I try, I get undefined method `tags'

• Alert Box Running First?

  - by corymathews

  I have some jQuery/JS below. The first thing to run is the alert box at the end. $(document).ready(function() { $("#id1 img , .msg").stop().animate( { width: '300px', height: '300px'}, { duration: 'slow', easing: 'easeInSine' }).pause(3000); $(".msg").animate( { width: '50px', height: '50px' }, { duration: 498, easing: 'easeOutSine' }); $("#id1 img").animate( { width: '50px', height: '50px' }, { duration: 500, easing: 'easeOutSine' }); $("#id1 img , .msg").animate( { width: '300px',height: '300px'}, { duration: 'slow', easing: 'easeInSine' }).pause(3000); alert('eh?'); }); I do have a easing plugin. If I run this the alert will show, and then the first animate will happen in the background but not be shown. It will just appear at the final size. Shouldn't the alert run at the end of all the animation? Can anyone explain why this is happening?

• Skeleton framework spacing

  I tried to ask this question late lastnight but I was so sleepy i typed the question completely wrong. I'm looking to float my navigation to the right of its current position around 200px more, there is room but it wont move over. You can view the live code here - www.xronn.co.uk/hosting and here is an image to explain my issue a little more http://i.stack.imgur.com/JtL0C.png purple lines the 960px width of the site blue line shows the space free for the navigation to go and the red arrows of course shows which direction i want the navigation to go in (the right) Anyone got any clue why when I push to more to the right, the list starts to sit under each other

• What machine learning algorithms can be used in this scenario?

  - by ExceptionHandler

  My data consists of objects as follows. Obj1 - Color - shape - size - price - ranking So I want to be able to predict what combination of color/shape/size/price is a good combination to get high ranking. Or even a combination could work like for eg: in order to get good ranking, the alg predicts best performance for this color and this shape. Something like that. What are the advisable algorithms for such a prediction? Also may be if you can briefly explain how I can approach towards the model building I would really appreciate it. Say for eg: my data looks like Blue pentagon small $50.00 #5 Red Squre large $30.00 #3 So what is a useful prediction model that I should look at? What algorithm should I try to predict like say highest weightage is for price followed by color and then size. What if I wanted to predict in combinations like a Red small shape is less likely to higher rank compared to pink small shape . (In essence trying to combine more than one nominal values column to make the prediction)

• C++ inheritance doubt

  - by Poiuyt

  Can you explain why this is not allowed, #include <stdio.h> class B { private: int a; public: int a; }; int main() { return 0; } while this is? #include <stdio.h> class A { public: int a; }; class B : public A{ private: int a; }; int main() { return 0; } In both the cases, we have one public and one private variable named a in class B.

• Eclipse debug - line: not available

  - by Mike

  I can't seem to find anything on google telling me why this might be and what the resolution is. I'm Stepping through third party code (that I have the source for) and would really like to see the current line being executed... Looking at javac compile flags, I see the -g:none flag. If this flag is set, would this be enough to explain why I'm not able to see line numbers? If so, why would someone do this, are there performance implications? Do I need to recompile the jar myself to attach the missing debug info (if possible)? Thanks!

• XCode Project Code Changes Not Updating 100% After Save-Build-Run

  - by Greg

  When I make code changes to my iPhone game project in XCode, and then do CMD-B + Enter, I expect the project to be saved, build and run on the simulator with the latest. What is happening though, sometimes, is that it doesn't pick up a small change I make unless I clean the project and then build. I'm a long time Java person and newish to C-based languages and it's compiler. Can someone explain to me what is cached after each build that does this and how to change my project settings to avoid having to clean everytime? Or tell me the bad news that this is part of C development? Not trying to bash it - I get compiled JSPs stuck in the working cache often in Java, too. :P

  hi here's my question : well I want build a wp7 control,so I write it and all go well, but the problem is that I can intercept on write(see onItemsSourcePropertyChanged)but not on read I would like explain better: public static readonly DependencyProperty ItemsSourceProperty= DependencyProperty.Register( "ItemsSource", typeof(ObservableCollection<ObjWithDesc>), typeof(HorizontalListBox), new PropertyMetadata(OnItemsSourcePropertyChanged) ); static void OnItemsSourcePropertyChanged(DependencyObject obj,DependencyPropertyChangedEventArgs e) { ((HorizontalListBox) obj).OnItemsSourcePropertyChanged(e); } OnItemsSourcePropertyChanged is called when I use SetValue(dp,..) but there isn't onItemsSourcePropertyRead ? that is called when I Use GetValue()? thanks
