• What is __path__ useful for?

  - by Jason Baker

  I had never noticed the __path__ attribute that gets defined on some of my packages before today. According to the documentation: Packages support one more special attribute, __path__. This is initialized to be a list containing the name of the directory holding the package’s __init__.py before the code in that file is executed. This variable can be modified; doing so affects future searches for modules and subpackages contained in the package. While this feature is not often needed, it can be used to extend the set of modules found in a package. Could somebody explain to me what exactly this means and why I would ever want to use it?

• Excel VBA : Changing string in cells

  - by user1265125

  I have cells with data like these: ABCD123XYZ MPOP345MLU . . . . What I want to do is, to remove the 3rd and 4th character from all these cells, hence giving AB123XYZ MP345MLU How do I do this in VBA? I have no idea about this language, and if someone can guide me in the right direction, it'd be great :) I understand I have to: 1. Declare 2 string variables st1 and st2 2. Store data from cell A1 into the variable st1 3. Copy all but the 2nd and 3rd char into str2 4. Output Str2 into B1 5. Move to A2

• Selecting an option with javascript

  - by Fibericon

  I have a drop down menu that I want to have selected on page load. This is what I'm using at the moment: var selector = document.getElementById("action_person").firstChild; var n = 0; while(selector.options[n] != null) { if(selector.options[n].value == "person") { selector.options.selectedIndex = n; } n++; } I've also tried replacing selector.options.selectedIndex = n with selector.options[n].selected = true. However, it never selects for me. It always shows the item at the top of the drop down. I've verified that the value "person" does exist in the drop down, and that the variable "selector" does point to a valid drop down. What am I doing wrong here?

• what are the differences in the WebKit nightly build binary and in the Safari binary?

  - by Albert

  I know what the projects are about: Safari is Apples browser. WebKit is the engine used in Safari (and in many other browsers) which is open source. The WebKit source code contains also code to compile it as a standalone application. You can download the nightly build of WebKit here: http://nightly.webkit.org/ I have compared some of those nightly builds of WebKit to the official Safari application. And besides the slightly different logo and the different name, I haven't really seen any difference. Are there any? Or is it just the branding? Edit: I just tried again with the current nightly build of today and it even names itself "Safari" now.

• Javascript function returning number with two decimals...?

  - by muzzledBYbrass

  I have a function to return points along a line and my return comes back with two decimal points...? For example, a return of my variable px will be something like -88.4029.032940598. vx is the x vector and mult is the distance of the line plus distance to calculate the point. Here is the operation that is returning these values: var mult = parseFloat(mag + theUnit); var px = coord_one.x_point + (vx * mult); console.log(px); Never have seen this before- I appreciate any and all help!

• Proper programming procedure?

  - by Rob

  I am creating a scoring application which is dependent upon what a user selects at the beginning menu. Example: If a user clicks 18, I want it to base itself off 18 holes of golf. If a user clicks 9, I want it to base itself off 9 holes of golf. Is it better to create a separate class for the code for 9 holes, and then another for 18 holes and then launch whichever depending on what the user selects? Or should I keep everything in 1 file and use a global variable to define different parameters? Still very new to android programming (or programming in general) so not sure of the proper "etiquette" if you will... Also what would be the pro's and con's of doing it either way? (If any) Thanks in advance!

• Struts 1 - problem in showing ActionMessages through a JSP page

  - by Yatendra Goel

  I am using Struts 1.3.10. I am trying to display ActionMessage and ActionError set by Action class through a JSP page. The problem is that the ActionErrors are displaying well but ActionMessages are not displaying. When I debug the application, I found that the messages (reference variable of ActionMessages) contains messages. I also saved those messages through saveMessages(request, messages) method of Action class. So, I think that the problem is in the JSP code through which I am trying to display those messages. The JSP code is as follows: <logic:messagesPresent> <ul id="messsages"> <html:messages id="msg" message="true"> <li><bean:write name="msg"/> </li> </html:messages> </ul> </logic:messagesPresent>

• Accessing php $_SESSION from python (wsgi) - is it possible?

  - by Bill Zimmerman

  Hi, I've got a python/WSGI app which needs to check to see if a user has logged on to a PHP web app. The problem is that the PHP app checks if a user has logged on by comparing a value in the $_SESSION variable to a value in the cookie from the user's browser. I would prefer to avoid changing the behavior of the php app if at all possible. My questions: Is there anyway I can access the session variables from within python? Where should I start to look? Are there any obvious security/performance issues I should be aware of when taking this approach?

• Coarse classing based on weight of evidence in r

  - by user3619169

  How can we use weight of evidence for binning continuous data in R. For e.g. I have a data: Recency 364 91 692 13 126 4 40 93 13 33 262 12 136 21 88 16 4 19 24 89 36 5 274 125 740 6 13 715 591 443 104 853 260 125 62 357 559 155 163 16 433 91 1380 96 374 130 574 101 5 11 34 401 13 215 168 So, what should be the command to bin this variable in different groups, based on Weight of evidence, or you can say coarse classing. Output I want is: Group I: Recency <200 Group I: Recency 200-400 Group I: Recency 400 Thanks

• Problem with url_for in ActionMailer template

  - by macek

  I'm attempting to provide a confirmation link in my user welcome email and I'm getting the following Rails error: Need controller and action! It makes a fuss about this line: <p>Please take a moment to activate your account by going to: <%= link_to confirm_user_url(:id => @user.confirmation_code) %>.</p> In my development.rb environment, I have the following line: config.action_mailer.default_url_options = { :host => "localhost", :port => 3000 } There's no problem with the @user variable. I've tested the email with things like @user.username and @user.confirmation_code. I'm only getting trouble with url_for and named routes like confirm_user_url. When I check my routes with rake routes, confirm_user shows up, so it's not an issue with the named route not existing. I can't seem to figure it out. What gives?

• Java, searching within a list of objects?

  - by Rick

  I'm a bit lost on the way to make this happen the fastest. I have a large list of objects that have basic variable attributes (with getters / setters) and I need to do a search in this list to find the objects within the list that match a given parameter I have found how to do a regular list search but I need to, for example search for the value of the result of doing a call getName() for each object in the list and get objects that have a result that matches my input. Something like below where the third argument is the result of the method call and the second is what I am trying to find. int index = Collections.binarySearch(myList, "value", getName()); Any advice is appreciated

• Concatenating a Text in front of Individual Database Records with Tcl

  - by DFM

  Hello: In short, currently I am using the following code to pull records from multiple tables in a Sqlite Db and insert them in a single combobox ($SearchBar): set SrchVals1 [db eval {SELECT DISTINCT Stitle From Subcontract Order By Stitle ASC}] set SrchVals2 [db eval {... set SrchVals3 ... set SrchValsALL [concat $SrchVals1 $SrchVals2 $SrchVals3] $SearchBar configure -value $SrchValsAll For the variable "SrchVals1", I am trying to figure out a way to concatenate the text "Sub: " to each individual record in SrchVals1. For example, if SrchVals1 shows the following records in the combobox: First Title Second Title Third Title I would like to concatenate so that the records in the combobox look like this: Sub: First Title Sub: Second Title Sub: Third Title I understand that I might have to use a foreach statement; however, I am having no luck writing one that adds "Sub: " in front of each record, as opposed to one. This seems like something that should be pretty easy, but I cannot seem to figure it out. Does anyone know how I can achieve these results? Thank you, DFM

• Creating hashmap/map from XML resources

  - by KimAMartinsen

  Hi! I'm making an application where a web service fetches (amongst other) a bunch of codes from a webservice (I.e BEL, FRA, SWE). During runtime I want to translate these codes to their apporiate names to display to users (I.e Belgium, France, Sweden). There can be a lot of these codes, so i'm wondering if there is any approriate way to store the (code, name) entry as a some sort of map in the XML resources in Android, so I can quickly fetch the name by the given code? It's all about speed here, since the map can have a few hundred entries.

  This is the code for my array (which is working) Public numUsers As Integer Public fNameUsers As String = ("..\..\..\users.txt") Public UserRecords As Usersclass() 'note... this line is in a module ' reader = New System.IO.StreamReader(fNameUsers) numUsers = 0 'Split the array up at each delimiter of "," and add new objects ' Do While reader.Peek <> -1 ReDim Preserve UserRecords(numUsers) oneline = reader.ReadLine fields = oneline.Split(",") UserRecords(numUsers) = New Usersclass UserRecords(numUsers).AccountNumber = fields(0) UserRecords(numUsers).CourseName = fields(1) UserRecords(numUsers).FirstName = fields(2) UserRecords(numUsers).LastName = fields(3) UserRecords(numUsers).DOB = fields(4) UserRecords(numUsers).Email = fields(5) UserRecords(numUsers).CourseProgress = (6) UserRecords(numUsers).AdminCheck = fields(7) numUsers = numUsers + 1 Loop reader.Close() My problem is that I don't know how to lookup the index of an array where the .accountNumber = a variable. For example the acccountNumber is 253, what is the code to find the index this relates to???? Thanks in advance

• C - memset segfault for statically allocated char array

  - by user1327031

  I get a segfault when trying to memset an array of chars that was allocated statically, but not for an array of the same length that was allocated using malloc. variable definitions: //static char inBuff[IN_BUFF_LEN]; //dynamic char * inBuffD; function call: //static, cast used because char** != char (*) [n] serverInit(portNum, (char**) &inBuff, &serv_addr, &sockfd) //dynamic serverInit(portNum, &inBuffD, &serv_addr, &sockfd) use within the function: memset(*inBuffAdr, 0, IN_BUFF_LEN); I suspect that my problem is in the difference of the function calls, or to be more precise, my incomplete understanding of the "char** != char (*) [n]" situation. But I have been banging at this for too long and can't see the forest from the trees so any hints and advice would be very appreciated.

• drop-down combo box-like functionality for queries.

  - by Frank Developer

  Is it possible to provide the following type of fuctionality with informix client tools? As the user types the first two characters of a name, the drop-down list is empty. At the third character, the list fills with just the names beginning with those three characters. At the fourth character, MS-Access completes the first matching name (assuming the combo's AutoExpand is on). Once enough characters are typed to identify the customer, the user tabs to the next field. The time taken to load the combo between keystrokes is minimal. This occurs once only for each entry, unless the user backspaces through the first three characters again. If your list still contains too many records, you can reduce them by another order of magnitude by changing the value of constant conSuburbMin from 3 to 4.

• [java] Threading socket handler for two sided communication in tcp port

  - by raven

  I want to make a chat which will be programed in java. one computer will host the server and the other one will initiate the socket [tcp port]. now from what I read there should be a loop that will constantly read the socket which means it will make the code stuck. I have a button that is 'actionperformed' on mouse release, I want to know if it will work along with the loops that constantly reads the socket so that it will also send the infromation I wrote. If I must thread it, I want to know if the run() method must be void because if I thread it it will mean creating a new class, and the whole GUI is one big class which includes a text area, and it's private. also how can I extract the information from the socket directly to the text area? lets say the textarea variable is called "chatOutput". thx :)

• From Fraction to Decimal and Back?

A bonus question ;) - Is there an easy way to calculate a decimal value to a fraction? Thanks..
