  • Subprocess statement works in python console but not work in Serverdensity plugin?

    - by maxigs
    in the python console the following statement works perfectly fine (i guess using eval that way is not really good, but its just for testing purpose in this case and will be replaced with proper parsing) $ python >>> import subprocess >>> r = subprocess.Popen(['/home/kupferwerk/sd-agent-plugins/plugin1.rb'], stdout=subprocess.PIPE, close_fds=True).communicate()[0] >>> data = eval(r) >>> data {'test': 1} when i convert this into a Serverdensity plugin however it keeps crashing the agent.py daemon everytime it executes the plugin. i was able to narrow it down to the subprocess line but could not find out why. exception catching did not seem to work also. here how the plugin looks like: class plugin1: def run(self): r = subprocess.Popen(['/pathto/plugin1.rb'], stdout=subprocess.PIPE, close_fds=True).communicate()[0] data = eval(r) return data I'm quite new to work with python and cant really figure out why this wont work. Thanks a lot for ideas :)

    I have 2 tables "user", "contact", the relation between two tables is one user has many contact Table member m_id name ------------ Table Contact c_id c_m_id value in zend model class, i do it in this way /* Member.php */ class Default_Model_DbTable_Member extends Zend_Db_Table_Abstract { protected $_name = 'member'; protected $_dependentTables = array('Default_Model_DbTable_Contact'); } /* Contact.php */ class Default_Model_DbTable_Contact extends Zend_Db_Table_Abstract { protected $_name = 'contact'; protected $_referenceMap = array( 'Member' => array( 'columns'=> array('c_id'), 'refTableClass'=> 'Default_Model_DbTable_Member', 'refColumns'=> array('c_m_id') ) ); /* IndexController.php */ class IndexController extends Zend_Controller_Action { public function indexAction() { $m= new Default_Model_DbTable_Member(); $row = $m->find(1); $data = $row->current(); $data = $data->findDependentRowset('Default_Model_DbTable_Contact'); print_r($data->toArray()); } } But i just get Invalid parameter number: no parameters were bound , my goal is to search a member detail record, and it also contains a array which store all contact info (i can use join method to do that, but i just want to try zend feature)

  • Question about how AppFabric's cache feature can be used.

    - by Kevin Buchan
    Question about how AppFabric's cache feature can be used. I apologize for asking a question that I should be able to answer from the documentation, but I have read and read and searched and cannot answer this question, which leads me to believe that I have a fundamentally flawed understanding of what AppFabric's caching capabilities are intended for. I work for a geographically disperse company. We have a particular application that was originally written as a client/server application. It’s so massive and business critical that we want to baby step converting it to a better architected solution. One of the ideas we had was to convert the app to read its data using WCF calls to a co-located web server that would cache communication with the database in the United States. The nature of the application is such that everyone will tend to be viewing the same 2000 records or so with only occasional updates and those updates will be made by a limited set of users. I was hoping that AppFabric’s cache mechanism would allow me to set up one global cache and when a user in Asia, for example, requested data that was not in the cache or was stale that the web server would read from the database in the USA, provide the data to the user, then update the cache which would propagate that data to the other web servers so that they would know not to go back to the database themselves. Can AppFabric work this way or should I just have the servers retrieve their own data from the database?

  • jQuery::Ajax success never occurs

    - by Legend
    I have an ajax call in the head section of my index.html $.ajax({ method: 'get', url : 'php/getRecord.php?color=red', dataType: "json", success: function (data) { alert(data); } }); For some reason, that alert never gets called. Am I doing something wrong? The PHP file does give me data when testing it directly.

  • Architecture for analysing search result impressions/clicks to improve future searches

    - by Hais
    We have a large database of items (10m+) stored in MySQL and intend to implement search on metadata on these items, taking advantage of something like Sphinx. The dataset will be changing slightly on a daily basis so Sphinx will be re-indexing daily. However we want the algorithm to self-learn and improve search results by analysing impression and click data so that we provide better results for our customers on that search term, and possibly other similar search terms too. I've been reading up on Hadoop and it seems like it has the potential to crunch all this data, although I'm still unsure how to approach it. Amazon has tutorials for compiling impression vs click data using MapReduce but I can't see how to get this data in a useable format. My idea is that when a search term comes in I query Sphinx to get all the matching items from the dataset, then query the analytics (compiled on an hourly basis or similar) so that we know the most popular items for that search term, then cache the final results using something like Memcached, Membase or similar. Am I along the right lines here?

  • Symmetric Encryption: Performance Questions

    - by cam
    Does the performance of a symmetric encryption algorithm depend on the amount of data being encrypted? Suppose I have about 1000 bytes I need to send over the network rapidly, is it better to encrypt 50 bytes of data 20 times, or 1000 bytes at once? Which will be faster? Does it depend on the algorithm used? If so, what's the highest performing, most secure algorithm for amounts of data under 512 bytes?

  • Rearrange array

    - by bradenkeith
    Array starts like this: Array ( [SMART Board] => Array ( [0] => sb1 [1] => sb2 [2] => sb3 ) [Projector] => Array ( [0] => pr1 [1] => pr2 [2] => pr3 ) [Speakers] => Array ( [0] => sp1 [1] => sp2 [2] => sp3 ) [Splitter] => Array ( [0] => spl1 [1] => spl2 [2] => spl3 ) [Wireless Slate] => Array ( [0] => ws1 [1] => ws2 [2] => ws3 ) ) The keys are used as my table columns titles. Their individual arrays are to carry the column information. I have split it up even further with array_slice and array_merge_recursive to look pretty as 2 arrays - 1 holds the column names, the other looks like this: Array ( [0] => sb1 [1] => sb2 [2] => sb3 [3] => pr1 [4] => pr2 [5] => pr3 [6] => sp1 [7] => sp2 [8] => sp3 [9] => spl1 [10] => spl2 [11] => spl3 [12] => ws1 [13] => ws2 [14] => ws3 ) However, when trying to write the table I'm getting keys 0, 1, 2 as the column data, then row break then 3, 4, 5 then row break... etc. I need it to be 0, 3, 6, 9, 12 row break 1, 4, 7, 10, 13 row break etc... How can I either rearrange my array to allow for this, or rewrite how the data goes into the table so that the correct information lines up with the appropriate column? foreach(unserialize($dl->data) as $data){ //first 3 are specialinstructions, system, and room $uniques = array_slice($data,0,3); $rows = array_slice($data,3); $rows2 = array_merge_recursive($rows2, $rows); //get the specialinstructions, system, and room foreach($uniques as $unique){ echo $unique."<br/>"; }///foreach uniques echo "<br>"; }///foreach unserialized $numberofrooms = count($rows2[key($rows2)]); $numberofproducts = count($rows2); print_r($rows2); unset($rows); //write the individual rows foreach($rows2 as $header=>$rowset){ $headers[] = $header; foreach($rowset as $row){ $rows[] = $row; }//foreach rowset }//foreach rows2 echo "<p>"; print_r($rows); echo '<table class="data-table"> <caption>DL</caption> <thead><tr>'; foreach($headers as $header){ echo "<th>".$header."</th>"; } echo '</tr></thead>'; echo '<tbody>'; $i = 0; foreach($rows as $row){ if($i == 3 || $i == 0){ echo "<tr>"; $i = 1; } echo '<td>'.$row.'</td>'; if($i == 2){ echo "</tr>"; } $i++; } echo '</tbody></table>';

  • How to convert a byte array of 19200 bytes in size where each byte represents 4 pixels (2 bits per p

    - by Klinger
    I am communicating with an instrument (remote controlling it) and one of the things I need to do is to draw the instrument screen. In order to get the screen I issue a command and the instrument replies with an array of bytes that represents the screen. Below is what the instrument manual has to say about converting the response to the actual screen: The command retrieves the framebuffer data used for the display. It is 19200 bytes in size, 2-bits per pixel, 4 pixels per byte arranged as 320x240 characteres. The data is sent in RLE encoded form. To convert this data into a BMP for use in Windows, it needs to be turned into a 4BPP. Also note that BMP files are upside down relative to this data, i.e. the top display line is the last line in the BMP. I managed to unpack the data, but now I am stuck on how to actually go from the unpacked byte array to a bitmap. My background on this is pretty close to zero and my searches have not revealed much either. I am looking for directions and/or articles I could use to help me undestand how to get this done. Any code or even pseudo code would also help. :-) So, just to summarize it all: How to convert a byte array of 19200 bytes in size, where each byte represents 4 pixels (2 bits per pixel), to a bitmap arranged as 320x240 characters. Thanks in advance.

  • how many dojo fliteringselect can I have on a form?

    - by Grant Collins
    I have a quick question How many dojo filteringselects can I have on a form? I have a form with 2 filteringselects on it, both getting data from different json datastores to populate the values. However only the first filteringselect is being populated, the other grabs no data. I am using Zend Framework and Zend_Dojo_Form to create the form elements for this. Many thanks. Ok looks like my code is broken somewhere then. The element that is failing in my form is: $location = new Zend_Dojo_Form_Element_FilteringSelect('location'); $location->setAutocomplete(true) ->setStoreId('countiesstore') ->setStoreType('dojo.data.ItemFileReadStore') ->setStoreParams(array('url' => $baseUrl.'/dojo/counties')) ->setAttrib('searchAttr', 'title') ->setRequired(true) ->removeDecorator('DtDdWrapper') ->removeDecorator('label') ->removeDecorator('HtmlTag') ->removeDecorator('Error'); When I go to http://localhost/dojo/counties I get the json file to read, but the element isn't populated with any data. Any ideas?

  • Object reference not set to an instance of an object- Linked List Example

    I am seeing following errors : Object reference not set to an instance of an object! Check to determinate if the object is null before calling the method! I'am new with C#,and I made a program for Sorted Linked Lists. Here is the code where the error comes! public void Insert(double data) { Link newLink = new Link(data); Link current = first; Link previous = null; if (first == null) { first = newLink; } else { while (data > current.DData && current != null) { previous = current; current = current.Next; } previous.Next = newLink; newLink.Next = current; } } It says that the current referenc is null while (data current.DData && current != null), but I assigned it current = first; Please Help ! The rest is the complete code of the Program! class Link { double dData; Link next=null; public Link Next { get { return next; } set { next = value; } } public double DData { get { return dData; } set { dData = value; } } public Link(double dData) { this.dData = dData; } public void DisplayLink() { Console.WriteLine("Link : "+ dData); } } class SortedList { Link first; public SortedList() { first = null; } public bool IsEmpty() { return (this.first == null); } public void Insert(double data) { Link newLink = new Link(data); Link current = first; Link previous = null; if (first == null) { first = newLink; } else { while (data > current.DData && current != null) { previous = current; current = current.Next; } previous.Next = newLink; newLink.Next = current; } } public Link Remove() { Link temp = first; first = first.Next; return temp; } public void DisplayList() { Link current; current = first; Console.WriteLine("Display the List!"); while (current != null) { current.DisplayLink(); current = current.Next; } } } class SortedListApp { public void TestSortedList() { SortedList newList = new SortedList(); newList.Insert(20); newList.Insert(22); newList.Insert(100); newList.Insert(1000); newList.Insert(15); newList.Insert(11); newList.DisplayList(); newList.Remove(); newList.DisplayList(); } }

  • How use AppEngine's Datastore Admin: Copy to Another App Feature

    - by Nick Siderakis
    I recently enabled AppEngine's Datastore Admin. I do not understand the instructions on how to copy my data to another app. Note: The target application must enable remote_api and must include this application’s ID in its HTTP_X_APPENGINE_INBOUND_APPID list. WARNING This application’s data is writable. We can only guarantee a consistent copy when the data being copied is read-only. Note: Blobs (binary data) will not be copied. To enable the remote_api I included the following in the app.yaml: builtins: - remote_api: on I have no idea what HTTP_X_APPENGINE_INBOUND_APPID is, and a Google search yields no results....any ideas?

  • Qt: QAbstractItemModel and 'const'

    - by Eye of Hell
    Hello. I'm trying to use a QTreeView for a first time, with a QAbstractItemModel. And instantly it's a problem: QAbstractItemModel interface declares methods as 'const', assuming they will not change data. But i want a result of SQL query displayed, and returning data for a record with specified indeq REQUIRES to use QSqlQuery::seek() that is a non-const. Is it any 'official' guideline to use a QAbstractItemModel with data that MUST be changed in order to get number of items, data per item etc? Or i must hack C++ with const casts?

  • How to build a LINQ query from text at runtime?

    - by Danvil
    I have a class A { public int X; public double Y; public string Z; // and more fields/properties ... }; and a List<A> data and can build a linq query like e.g. var q = from a in data where a.X > 20 select new {a.Y, a.Z}; Then dataGridView1.DataSource = q.ToList(); displays the selection in my DataGridView. Now the question, is it possible to build the query from a text the user has entered at runtime? Like var q = QueryFromText("from a in data where a.X > 20 select new {a.Y, a.Z}"); The point being, that the user (having programming skills) can dynamically and freely select the displayed data.

  • Allowing Xform controls for optional XML elements

    - by Cam
    Hi, In designing an XForm interface to an XML database (using eXist and XSLTForms), I'd like to include an input control for an optional element. The XML data records already exist and while some contain the optional element, others don't. To update a record, I'm using the existing XML record as the model instance. The problem is that the form control is not displayed when the optional element is not present, which is logical, but presents a problem when a user wants to add data to the optional element. To be more explicit, here's an example data record, data.xml: <a> <b>content</b> </a> with RNC schema: start = element a { element b { text }, element notes { text }? } XForms model: <xf:model> <xf:instance xmlns="" src="data.xml"/> <xf:submission id="save" method="post" action="update.xq" /> </xf:model> And control: <xf:input ref="/a/notes"> <xf:label>Notes (optional): </xf:label> </xf:input> The problem is that the 'Notes' input control is simply not displayed. An obvious solution is to add a trigger button to allow the user to insert the element if needed, but it is preferable to just have the input control appear, and be empty. My question is: is there some subtle combination of lesser-know attributes/binds/multiple instances/xpath expressions that will cause the control to always be displayed? Thanks

  • EGODatabase does not retain inserted record

    - by user135775
    Hi Guy! I'm using EGODatabase to process my data. When I tried to insert data into the database which I created with Base and attached to the project, the data that was inserted programmatically will not show up when I restart my app.However the data inserted manually using Base will show up just fine. Following is the code for inserting data into the database: NSString *path = [[NSBundle mainBundle] pathForResource:@"Database" ofType:@"db"]; db = [EGODatabase databaseWithPath:path]; if ([db open]) { NSLog(@"Database is opened successfully!"); } else { NSLog(@"Database is failed to open!"); } NSArray *params = [NSArray arrayWithObjects:[aFeed feedID], [aFeed title], nil]; [db executeUpdate:@"Insert INTO Feed (FeedID, Title) VALUES (?, ?)" parameters:params]; EGODatabaseResult *results = [db executeQuery:@"SELECT * FROM Feed"]; for ( EGODatabaseRow * row in results) { NSLog(@"ID: %@ Title: %@", [row stringForColumn:@"FeedID"], [row stringForColumn:@"Title"]); } I appreciate if anyone can share me a working sample code for EGODatabase. I'm using EGODatabase because I might have multi-threading code that write to the database. Thank in advance.

  • Javascript Shift+Enter (Firefox)

    - by Stephen MCGinley
    Hi guys, Had a look and found some things on this, but nothing seems to work as I'd like it. Initially I had my solution working with internet explorer and chrome, but not firefox (which is unsatisfactory for me to not have working) What I'm looking for is a simple text area, which sends data on enter key, but creates a new line on Shift+Enter. The following is what I have function goReturn(e,str) { var e = (window.Event) ? e.which : e.keyCode; if (e.shiftKey && e=="13") { document.getElementById("wall").value = document.getElementById("wall").value+"\n"; } else if(e=="13"){ // ...continue to send data } } This sends the data on enter, but also sends the data on shift and enter (which is the problem I have). Thanks for any assistance
