  • Strange Array#each Ruby behaviour

    - by with a dot.
    The question is a bit vague, but I am not really sure why this happens: I have the following code: p user.room.users.length user.room.users.each {|usr| puts "b" } user.room.users.each {|usr| puts "a"; usr.enter(Room[Config::entrance]) } which outputs: 5 b b b b b a a a I also made User#enter count how many times it's been called and it returns 3! I am completely baffled by this behaviour. I doubt the code within User#enter is the cause, but if someone thinks it might be relevant I can provide it (I don't want to clutter the question unnecessarily). Edit If it's relevant I am using ruby-1.9.3-p125

  • Drupal: create a node with employee working hours

    - by JMarshall
    I have a bit complicated task. 1. I need to create a node with employee working hours (it's gonna be created for all users with role "employee"), which looks like this: Monday: From __ : __ To __ : __ Tuesday: From __ : __ To __ : __ Wednesday: From __ : __ To __ : __ etc. So, I'll have to create probably 14 CCK fields (monday_from, monday_to, tuesday_from...) or more to store the day of the week and workging hours (hours and minutes). 2. I need to add a view with exposed filters, where visitors can filter employees by day of the week and working hours. What kind of field should I use for working hours? How could views filtering described above be achieved? Any suggestions are greatly appreciated. Thank you!

  • Split Entire Hash Range Into n Equal Ranges

    - by noxtion
    Hello. I am looking to take a hash range (md5 or sha1) and split it into n equal ranges. For example, if n=5, the entire hash range would be split by 5 so that there would be a uniform distribution of key ranges. I would like n=1 to be from the beginning of the hash range to 1/5, 2 from 1/2 to 2/5, etc all the way to the end. I am new to hashing and a little bit unsure of where I could start on solving this for a project. Any help you could give would be great.

  • Broadcast message or file to nearby Bluetooth devices

    - by Medjeti
    Hiya, A client of ours is attending a business fair and would like to push some sort of "welcome message" to people visiting their space. I'm not too familiar with Bluetooth, so I have a few questions: What kind of content can you transfer via Bluetooth? (Is it files only or is it possible to send a simple text message?) Is it possible to push content only to recipients within a certain distance? (ie. based on signal strength or similar) Can anybody recommend a piece of software that can do some or all of the above? If necessary we could program a custom solution ourselves (.NET), but I'm sure there must be a program out there that can do the job. I've googled a bit and came across the 32feet.NET framework - does anybody have any experience with this framework? Thanks in advance for any suggestions!

  • BATCH - wait for executable to finish before starting next result

    - by user3697573
    I'm pretty much a noob at this, so any help is appreciated. I'm trying to run the video transcoding executable REDline on all .R3D files in a given folder. REDline only accepts single files, which is the issue. I finally got it to search recursively for the files I need, but my problem is the search function passes the next result to REDline before the first one is finished transcoding. I have the search results that need to run in a variable inside REDline. Here's the code: for /r D:\folder\ %%a in (*) do ( "C:/Program Files/REDCINE-X PRO 64-bit/REDLine.exe" --exportPreset "Prores_Intermediate" --i "%%~dpnxa" --useRSX 2 --masterRMDFolder "" -s 0 -e 95 ) After about .7 seconds, REDline reports 'received stop message from client'. I don't think this is a REDline error, as I have been able to transcode single files successfully. Thanks.

  • Why do C# and Java require everything to be in a class?

    - by Javier Badia
    It seemed like this question should have been asked before, but searching found nothing. I've always wondered what's the point of making us put every bit of code inside a class or interface. I seem to remember that there were some advantages to requiring a main() function like C, but nothing for classes. Languages like Python are, in a way, even more object oriented than Java since they don't have primitives, but you can put code wherever you want. Is this some sort of "misinterpretation" of OOP? After all, you can write procedural code like you would in C and put it inside a class, but it won't be object oriented.

  • Get data from Joomla jos_users table

    - by RobertR
    Hello, world! I'm trying to build a little bit advanced users system using Joomla, but I stuck at one spot. I added new field on Joomla's jos_users table, but when I wanted to get that field out, like "echo" - it didn't worked at all. Any other data, even password field I can get without problems. Of course, I added new value in /var/www/<project>/libraries/joomla/user/user.php like this after line 40. /** * The users address name * @var string */ var $address = null; What might be the problem here? Or what I did wrong, or what I didn't do at all? Thanks for replies! Cheerio

  • Inserting text into a textarea using .load() in jQuery

    - by bateman_ap
    Hi, having a bit of a nightmare, I am trying to use jQuery to insert some text taken from a .load() call into a form field (textfield) after a user logs in (basically prefilling some known details) The code I am using is: $.ajax({ type: "POST", url: "/ajax/login.php", data: dataString, success: function(html) { if (html == 1) { $("#loginPanel").load("/ajax/login-panel.php"); $("#bookName").load("/ajax/getSessionDetails.php #userUsername"); $("#bookEmail").load("/ajax/getSessionDetails.php #userEmail"); $("#bookingLogin").hide("fast"); } else { $("#loginError").html("Sorry, login failed, please try again"); } } }); If I hardcode such as $("#bookName").html("Test Content"); it works OK so it must be a problem with the .load call. I looked around and found some guy suggest something like the following code but I couldn't get it to work: $.get(htmlBannerUrl, function(data){ $('textarea').val(data); });

  • Operations on 64bit words in 32bit system

    - by Vilo
    I'm new here same as I'm new with assembly. I hope that you can help me to start. I'm using 32bit (i686) Ubuntu to make programs in assembly, using gcc compiler. I know that general-purpose-registers are 32bit (4 bytes) max, but what when I have to operate on 64 bit numbers? Intel's instruction says that higher bits are stored in %edx and lower in %eax Great... So how can I do something with this 2-registers number? I have to convert 64bit dec to bin, then save it to memory and show on the screen. How to make the 64bit quadword at start of the program in .data section?

  • JBoss 4.0.5 startup takes 15 minutes deploying a single war file

    - by dkblinux98
    This instance of JBoss deploys several war files. The rest of the JBoss startup takes about 5 minutes or less. But when it gets to one particular war file, startup just hangs with no further output to the jboss log. It waits there for about 15 minutes and then suddenly the war starts deploying. The rest of the JBoss startup is then fine. What I want to know is what steps do you recommend I take to diagnose the cause of this condition? It is not possible to upgrade this site to a newer version of JBoss nor java (currently 1.5.0.7). It is running on 32-bit CentOS 5.3 Linux on 3 xen-based virtual servers in a load balanced configuration. The code is common to all three servers via an nfs share. This same issue was seen, however, when the 3 servers were physical and the code was local to each server. The servers are each 2 cpu, 4GB RAM servers.

  • Querying Same Lookup Table With Multiple Columns

    - by dmaruca
    I'm a bit confused on this. I have a data table structured like this: Table: Data DataID Val 1 Value 1 2 Value 2 3 Value 3 4 Value 4 Then I have another table structured like this: Table: Table1 Col1 Col2 1 2 3 4 4 3 2 1 Both columns from Table1 point to the data in the data table. How can I get this data to show in a query? For example, a query to return this: Query: Query1 Column1 Column2 Value 1 Value 2 Value 3 Value 4 Value 4 Value 3 Value 2 Value 1 I'm familiar enough with SQL to do a join with one column, but lost beyond that. Any help is appreciated. Sample sql or a link to something to read. Thanks! PS: This is in sqlite

  • How can I do a left outer join where both tables have a where clause?

    - by cdeszaq
    Here's the scenario: I have 2 tables: CREATE TABLE dbo.API_User ( id int NOT NULL, name nvarchar(255) NOT NULL, authorization_key varchar(255) NOT NULL, is_active bit NOT NULL ) ON [PRIMARY] CREATE TABLE dbo.Single_Sign_On_User ( id int NOT NULL IDENTITY (1, 1), API_User_id int NOT NULL, external_id varchar(255) NOT NULL, user_id int NULL ) ON [PRIMARY] What I am trying to return is the following: is_active for a given authorization_key The Single_Sign_On_User.id that matches the external_id/API_User_id pair if it exists or NULL if there is no such pair When I try this query: SELECT Single_Sign_On_User.id, API_User.is_active FROM API_User LEFT OUTER JOIN Single_Sign_On_User ON Single_Sign_On_User.API_User_id = API_User.id WHERE Single_Sign_On_User.external_id = 'test_ext_id' AND API_User.authorization_key = 'test' where the "test" API_User record exists but the "test_ext_id" record does not, and with no other values in either table, I get no records returned. When I use: SELECT Single_Sign_On_User.id, API_User.is_active FROM API_User LEFT OUTER JOIN Single_Sign_On_User ON Single_Sign_On_User.API_User_id = API_User.id WHERE API_User.authorization_key = 'test' I get the results I expect (NULL, 1), but that query doesn't allow me to find the "test_ext_id" record if it exists but would give me all records associated with the "test" API_User record. How can I get the results I am after?

  • Updating counters through Hibernate

    - by at
    This is an extremely common situation, so I'm expecting a good solution. Basically we need to update counters in our tables. As an example a web page visit: Web_Page -------- Id Url Visit_Count So in hibernate, we might have this code: webPage.setVisitCount(webPage.getVisitCount()+1); The problem there is reads in mysql by default don't pay attention to transactions. So a highly trafficked webpage will have inaccurate counts. The way I'm used to doing this type of thing is simply call: update Web_Page set Visit_Count=Visit_Count+1 where Id=12345; I guess my question is, how do I do that in Hibernate? And secondly, how can I do an update like this in Hibernate which is a bit more complex? update Web_Page wp set wp.Visit_Count=(select stats.Visits from Statistics stats where stats.Web_Page_Id=wp.Id) + 1 where Id=12345;

  • Load a CSV file into a DataGrid

    - by Calanus
    I'm having a go at moving one of our simpler apps to Silverlight (a bit of a learning exercise). I've quickly come unstuck as I can't figure out how to load (or bind maybe?) a csv file to a datagrid (i.e. so you can point the app at a local csv file and display it to the user). I do have boilerplate code to parse a csv file and return a datatable but I'm shocked to discover that Silverlight doesn't even support DataTable (wtf!). Any ideas at all how to do this? How do people bind data to a datagrid anyhow? I'm using Silverlight 3.0 included in VS2010.

  • Using an ActiveX object from an Outlook hosted webpage - possible?

    - by Nic Wise
    I'm trying to do the following: We have an outlook plugin, written in .NET (and C++). It does various things, and is manually installed on the end users machines (usually via AD deployment or similar) We are changing our search to use a webpage-based search, but from within outlook. That part is ok, however we want to communicate from the webpage to the surrounding outlook application. We can call into outlook by exposing an ActiveX object from our plugin, however we get security warnings, even if it's signed and marked as safe for scripting. Is this even possible? Has anyone done it? Anyone have a better way of doing it? We only need to pass in a small amount of data (a message id), and only from the webpage to outlook [update]: This is the error: automation server can't create object. We can get around it a bit by turning things off in IE, but thats not a good way to do it! Thanks

  • How can code in a JavaScript file get the file's URL?

    - by dalbaeb
    I need to dynamically load a CSS stylesheet into a page that's on a different domain. How can I get the complete URL of the JS file to use in the href attribute of the stylesheet? For instance, here is the structure: http://bla.com/js/script.js http://bla.com/css/style.css I want to dynamically load the stylesheet into a page http://boo.net/index.html. The problem is, I don't know the bla.com bit in advance, just the fact that the stylesheet is in ../css/ relative to the JS file. The script is, of course, included on index.html. jQuery's fine too.

  • Win32: Reading WS_VSCROLL style from a combo box (or list box)

    - by Adam Tegen
    I'm iterating through the controls in a dialog and I'm trying to determine if a combobox was created with the WS_VSCROLL style. The style, obtained from GetWindowLong(hwnd, GWL_STYLE), doesn't contain the WS_VSCROLL bit (0x200000), even when I know it was set on create. Clarification: I am looking to see if the ComboBox was created with the WS_VSCROLL style. Calling GetWindowLong() (or using spy++) to get the style of the combo's listbox will include WS_VSCROLL if a scrollbar is needed to based on the current contents of the list. I am trying to determine if the ComboBox was created with WS_VSCROLL, not if a scrollbar is currently visible.

  • Drupal and Back-End Complexity

    - by Brian
    Currently I am working on a school website, and we are still in the decision-making process of choosing a framework (we know that we're not using Joomla! or hand-coding). Drupal came up as a viable choice, and currently, that is my best bet for the site. However, I have an issue with CMS's in general. I would like to develop a quite complicated and specifically custom-suited back-end application for teachers to interact with individual students, including the design of shared/custom calendars, announcement privileges, etc. I currently have a bit of expertise with HTML, CSS, PHP, MySQL, and I could wrap my head around some JavaScript and AJAX stuff if need-be. However, would such a complicated application work with Drupal (in that I could create it to specifically suite my purposes)?

  • ValueError: setting an array element with a sequence.

However, this code works: import numpy as p a=range(24) b = p.reshape(a,(6,4)) c=p.array(b,dtype=p.float64)[:,2] I re-arranged the code a bit to put it into a cogent posting, but it should more or less have the same result. Can anyone show me what to do to fix the problem in the broken code above so that it stops throwing an error message?

  • movedown method not saving new position - cakephp tree

    - by Ryan
    Hi everyone, I am experiencing a problem that has popped up recently and is causing quite a bit of trouble for our system. The app we have relies on using the movedown method to organize content, but as of late it has stopped working and began to generate the following warning: Warning (2): array_values() [<a href='function.array-values'>function.array-values</a>]: The argument should be an array in [/usr/local/home/cake/cake_0_2_9/cake/libs/model/behaviors/tree.php, line 459] The line being referenced: list($node) = array_values($Model->find('first', array( 'conditions' => array($scope, $Model->escapeField() => $id), 'fields' => array($Model->primaryKey, $left, $right, $parent), 'recursive' => $recursive ))); The line calling the method: $this->movedown($id,abs((int)$position)); I have exhausted every idea I could come up with. Has anyone else crossed this issue before? Any help, or pointing in a direction would be much appreciated!

  • Framework for creating mock objects in Java

    - by Amir Rachum
    This is NOT a question about which is the best framework, etc. I have never used a mocking framework and I'm a bit puzzled by the idea. How does it know how to create the mock object? Is it done in runtime or generates a file? How do you know its behavior? And most importantly - what is the work flow of using such a framework (what is the step-by-step for creating a test). Can anyone explain? You can choose whichever framework you like for example, just say what it is.

  • Data validation between SQL replicated tables

    - by Vikram
    Hi All, I am trying to figure out a way to validate the data in my publisher and subscriber in SQL 2005 replication. I thought of using sp_publication_validation, but it needs db_owner permission and we are not allowed to have it in our company. So I did bit more reading and found out about two other SPs that I think work for me. First one is sp_article_validation, which I plan to run on the publisher. For each article that I call this SP, its gonna give the row count and a checksum. With that info, I intend to call sp_table_validation on the subscriber, passing the row count and checksum from the previous SP, there by validating both tables. What do you guys think? Is this a proven way to validate data in replication? There is very little documentation on these SPs. Here is the link: sp_table_validation - http://msdn.microsoft.com/en-us/library/aa239370(v=sql.80).aspx sp_article_validation - http://msdn.microsoft.com/en-us/library/ms177511(v=SQL.90).aspx Thanks for

  • UITableView not showing background image.

    - by K.Honda
    I have a uitableview with 2 cells (custom tableviewcells) and a button for login. I made them programmatically. Now I want to put a background image behind the 2 custom cells and the button. I went into IB and put the image view on top of the tableview and then put a picture on it which I want as the background. Then I went into viewDidLoad and put this bit of code tblSimpleTable.backgroundColor = [UIColor clearColor]; to clear the tableviews background colour. It now looks like this: But the background does not appear. Does anyone know how to fix this? Thanks.
