• Starting socket server in ruby on rails on cloud environments (heroku)

  - by ElTren

  Hi, I'm using heroku, and I can push a Ruby on Rails app just fine, I'm trying to convert this to a Socket server, basically I would need to bind to an open port, in this case, I know Heroku only does 80 22 and 443. Is it possible to bind to port 80 on those environments? Also, how would I setup the entry point for this socket server, all I know is that when script/server it boots up the app. Do I have to put the function call there? How can a socket server start instead of the rails app on top of whatever webserver heroku has.

• Multiple Foriegn Keys from One Table linking to single Primary Key in second Table

  - by croker10

  Hi all, I have a database with three tables, a household table, an adults table and a users table. The Household table contains two foreign keys, iAdult1ID and iAdult2ID. The Users table has a iUserID primary key and the Adult table has a corresponding iUserID foreign key. One of the columns in the Users table is strUsername, an e-mail address. I am trying to write a query that will allow me to search for an e-mail address for either adult that has a relation to the household. So I have two questions, assuming that all the values are not null, how can I do this? And two, in reality, iAdult2ID can be null, is it still possible to write a query to do this? Thanks for your help. Let me know if you need any more information.

• How to double the size of 8x8 Grid whilst keeping the relative position of certain tiles intact?

  - by ke3pup

  Hi guys I have grid size of size 8x8 , total of 64 Tiles. i'm using this Grid to implement java search algorithms such as BFS and DFS. The Grid has given forbidden Tiles (meaning they can't be traversed or be neighbour of any other tile) and Goal and Start tile. for example Tile 19,20,21,22 and 35, 39 are forbidden and 14 an 43 are the Goal and start node when the program runs. My question is , How can i double the size of the grid, to 16x16 whilst keeping the Relative position of forbidden tiles as well as the Relative position of start and goal Tiles intact? On paper i know i can do this by adding 4 rows and columns to all size but in coding terms i don't know how to make it work? Can someone please give any sort of hints?

  21 --Primitive recursion constructor 22 pr :: ([Int] -> Int) -> ([Int] -> Int) -> ([Int] -> Int) 23 pr f g = \xs 0 -> f xs 24 pr f g = \xs (y+1) -> g xs y ((pr f g) xs y) I want the function this function creates to act differently on different inputs, so that it can create a recursive function. As expected, the above code doesn't work. How do I do something like pattern matching, but for the function it creates? Thanks

• How to limit SMTP delivery to hourly batches

  - by Jeremy W

  In an effort to keep us from being labeled spammers by major ISPs (in addition to SPF records, privacy policies, CANSPAM compliance and the like) - I wanted to limit the amount of mail we send out an hour. Is this possible in W2K3 SMTP server? I was looking at outbound connection properties in the SMTP virtual server config screens...It's just not that clear if tinkering with those settings are going to do what I want. In a nutshell, I'd love mail being sent by this server to queue up and send for example, 5,000 messages every 10 minutes or so. Is this possible?

• C# sending mails with images inline using SmtpClient

  - by WebDevHobo

  SmtpClient() allows you to add attachments to your mails, but what if you wanna make an image appear when the mail opens, instead of attaching it? As I remember, it can be done with about 4 lines of code, but I don't remember how and I can't find it on the MSDN site. EDIT: I'm not using a website or anything, not even an IP address. The image(s) are located on a harddrive. When sent, they should be part of the mail. So, I guess I might wanna use an tag... but I'm not too sure, since my computer isn't broadcasting.

• Image processing custom filter 7 by 7

  - by ladiesMan217

  Lets say I have a 7 by 7 neighborhood around a pixel that looks like this 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 and I wanna filter the above by replacing the pixel p by the average of those pixels whose value lie in the range -10<=p_value <=10. I am new to image processing and I think in this case p_value is 25 and around 25 that are many pixel values in that range but don't exactly know to construct a convolution filter out of it.

• Creating a border around cells with the same value.

  - by Liam

  I have a table like the one below. How can I get Excel to put borders around groups with the same number in the 4th column so that there is a border around the groups. I was thinking conditional formatting could do it but I can't think how. So I think the only option is a macro.

• Irregular layout ItemsControl

  - by firoso

  I have a strange layout for an ItemsControl. I have a 4x6 grid with the following pattern: 1 2 3 4 13 14 15 16 5 6 7 8 17 18 19 20 9 10 11 12 21 22 23 24 Is there an easy way to do this? should I be using 6 Items Controls and take "sections" of my list? is there a good way to do this? What about notification? It's important to note that I may, or may not, have all 24 entries present, but the layout needs to be maintained (think of it like filled slots on a bingo card or something)

• updating a shape in scene with a for loop using javafx

  - by Susanta

  Following is a code fragment. I am updating a rectangle using a for loop when a button is pressed. This is a model for my ultimate intention of showing visualization of data model as it changes large number of times inside a for loop. It works but I see only one change. Now since I am changing the width randomly I should see large number of changes. It seems I am making a wrong assumption on something basic. The code goes below: 7 var rec: Rectangle = Rectangle { 8 x: 10, y: 10 9 width: 140, height: 90 10 fill: Color.BLACK 11 } 12 13 Stage { 14 title: "MyApp" 15 scene: Scene { 16 width: 200 17 height: 200 18 content: [ 19 rec, 20 Button { 21 text: "Button" 22 action: function () { 23 for (i in [1..999]) { 24 rec.width = 25 + java.lang.Math.random()*50; 25 } 26 } 27 } 28 ] 29 } 30 }

• Use of WebDAV to access OWA (exchange 2003) mails with Basic authentication and SSL

  - by Mayuresh

  I have got a working C# code for accessing OWA mails using WebDAV against a FBA enabled exchange 2003 (http://support.microsoft.com/kb/891748/en-us/) But my client's OWA (exchange 2003) has Basic authentication and SSL (i-e when I try to access the web mail link through browser I get a grey login box instead of a web page I can log into the mail box once I enter the correct details) But my same fails with a 401 error against this mailbox. I got the simple request working for the Basic authentication using – String usernamePassword = strUserName + ":" + strPassword; WebReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword))); But the subsequent WebDAV SEARCH request fails with 404 (resource not found) error. Can we use WebDAV against an exchange 2k3 with SSL and Basic authentication?

• Construct Numpy index given list of starting and ending positions

  - by Abiel

  I have two identically-sized numpy.array objects (both one-dimensional), one of which contains a list of starting index positions, and the other of which contains a list of ending index positions (alternatively you could say I have a list of starting positions and window lengths). In case it matters, the slices formed by the starting and ending positions are guaranteed to be non-overlapping. I am trying to figure out how to use these starting and ending positions to form an index for another array object, without having to use a loop. For example: import numpy as np start = np.array([1,7,20]) end = np.array([3,10,25]) Want to reference somearray[1,2,7,8,9,20,21,22,23,24])

• Maven/Ivy: Identical artifact with different name in dependency

  - by ThiamTeck

  Currently I am using Ivy for dependency management. And quite often I come across problem of getting identical jar files with different name due to transitive dependency. Example: <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>org.apache.geronimo.specs</groupId> <artifactId>geronimo-javamail_1.4_spec</artifactId> <version>1.4</version> </dependency> I am thinking of trying out Maven as well. Any best practice to eliminate these identical artifact in either Ivy or Maven?

• Getting data from JFrame AFTER the form is filled

  - by mary jane

  I'm trying to get data for my application from a form set in an external window (getDataWindow extends javax.swing.JFrame). The problem is that functions are executed before form is filled in. getDataWindow dataW=new getDataWindow(); dataW.setVisible(true); size=dataW.returnSize(); I've tried also adding additional boolean variable to getDataWindow getDataWindow dataW=new getDataWindow(); dataW.setVisible(true); while(!dataW.checkIfReady()){wait();} size=dataW.returnSize(); But it makes also the window wait (it appears but it's black inside and nothing happens). I think i should create some threads for that - I've tried to call a window making function getDataWindow in java.awt.EventQueue.invokeLater(new Runnable()) but I had to initialize dataW earlier so dataW.checkIfReady() could be called, so it is a catch 22.
