  • How can I pass environment variables to a WSGI script, using uWSGI?

    - by orokusaki
    I've added the following line to /etc/environment: FOO_DEPLOYMENT_ENV="vbox" Upon logging in via SSH, I can echo $FOO_DEPLOYMENT_ENV and, of course, see vbox output to the shell. If I open a Python shell and run os.getenv('FOO_DEPLOYMENT_ENV'), it will return 'vbox', but the same code in my Python application, when run by uWSGI (as the www-data user), it does not see the environment variable. Clearly, this isn't a problem of uWSGI, and is rather a problem with my understanding of environment variables, or how they're properly set, and the contexts in which they can be retrieved. What am I doing or understanding incorrectly?

  • Do CDNs actually dump the data to the client or pass the URL of the content?

    - by zengr
    I am curious, say for example: Facebook is the client of Akamai CDN. So, now when I login to my FaceBook page, I see all the content (vid, image, text etc) and I click on a video to view it. Now, Facebook is the client to Akami to get the content. So, when a request is made from Facebook to Akami, does Akamai dump the vid/image from their data centers to Facebook's data centers where they reside for a while (depending on their heuristics) and flushed after some time? Or, I see that video (stream it) directly from Akamai's server? UPDATE Data resides in CDN permanently (agreed), but is a copy of the content sent to Facebook's data centers too

  • How to pass $_GET variables to a PHP script via the command line?

    - by George Edison
    I am trying to create a webserver that serves PHP scripts. Currently, it works as follows: The client requests /index.php?test=value The server invokes php index.php The server feeds the HTTP request headers as STDIN to the PHP process The server reads the output of php from STDOUT and returns it to the client All of this is working except that the parameters are not being passed to the PHP script because: var_dump($_GET); returns: array(0) { } How do $_GET parameters get passed to the PHP binary when it is invoked?

  • Why do partially failed/failing switches fail to pass DHCP?

    - by David Mackintosh
    I've noticed this several times: a switch starts to behave oddly. Usually if the switch doesn't fail outright, what tends to get noticed is that DHCP doesn't work. We had a Linksys SRW-224P fail today. Systems which were still connected worked properly, until it came time to renew their DHCP lease. Once the lease expired, they stopped working, but up until then we couldn't detect a failure. This includes PoE VoIP phones -- they work fine until their lease is up, at which point they're done. I've noticed this on the above-mentioned Linksys, three varieties of 3Com, and possibly half a dozen dumb switches. What is it about DHCP that makes it sensitive to failing switches?

  • How to pass AppleScripts display dialog to Growl or growlnotify?

    - by pattulus
    I have this simple AppleScript which takes the text in the clipboard and outputs the amount of words and characters used. What I'm trying to do is passing "display dialog" to Growl or growlnotify. I know how to use growlnotify in the shell - it's great and highly customizable (stick note, assign app icon or an image, etc) - but the point is: I don't know how to do it in AppleScript. I google a bit but now time has passed and I decided to post my question here. So, here's the script: set myCount to count (the clipboard) set myWords to count words of (the clipboard) set myParas to count paragraphs of (the clipboard) display dialog "Characters: " & myCount & " Words: " & myWords & " Paragraphs: " & myParas Thanks.

  • Office documents on intranet all requiring second login and can't pass auth? Disable webdav?

    - by DOTang
    I am not sure what is going on, but recently all the Office documents on our intranet get prompted a second time for login and according to the error logs it looks like it's trying to use webdav to open (an editable?) version of the document to save directly on the server? We have no sharepoint server setup or anything, but this shouldn't be happening. All I want is for the document to be saved or opened from a local copy in temp like normal. Here is the log: Line 57499: 2011-04-12 15:57:10 (ip) OPTIONS (address) - 443 (username) (user ip) Microsoft-WebDAV-MiniRedir/6.1.7601 - 401 1 1326 1525 238 0 Line 57500: 2011-04-12 15:57:10 (ip) OPTIONS (address) - 443 (username) (user ip) Microsoft-WebDAV-MiniRedir/6.1.7601 - 401 1 1326 1525 238 0 Line 57501: 2011-04-12 15:57:10 (ip) OPTIONS (address) - 443 (username) (user ip) Microsoft-WebDAV-MiniRedir/6.1.7601 - 401 1 1326 1525 238 0 The log basically contains a bunch of these. How can I disable this behavior so that office documents that are downloaded aren't attempted to be used through webdav?? Edit: I should clarify behavior, it asks if you want to save or open it, upon choosing open open, it asks to re-authenicate, you put in the user information and the login box comes up 3 times acting like you entered the wrong password. For some users, after passing the login box the third time, it still opens up, for others their browser just locks up. It also doesn't even look like webdav is installed on our server, I see no config options in IIS for it as outlined on this page: http://learn.iis.net/page.aspx/350/installing-and-configuring-webdav-on-iis-7/#001

  • IIS asks for login/pass when accessed using hostname but not when ‘localhost’ is used. Why?

    - by sb
    Hi All, I have setup IIS on my xp machine and have setup a default homepage (that comes with the IIS installed). It is a help page I think. when I access the page with http : // localhost it works fine (IE/Chrome or FF) but when I access it using http://hostname it prompts for a loging/password and works when I enter my domain id and password on the intranet. I have ensured that "anonymous access" is enabled in the properties window of the default site and "websites" node. I searched stack overflow for similar queries but some indicate I need to change the IE/FF settings to allow "integrated security" etc and some suggest to look at the "log file". I don't want to change the IE setting and there is nothing unusual in the log file of the IIS Server. Can anybody help me figure out why this is happening? thank you sb

  • So long and thanks for the fish&hellip;

    - by Geoff N. Hiten
    This marks my last post as a SQLPASS Board member.  I learned a lot during my year of service and I thank everyone involved for this opportunity.  I would especially like to thank the Chapter leaders and Regional Mentors for Virtual Chapters who (mostly) patiently taught me about Virtual Chapters.   I hope the changes I put in place will help strengthen and grow VCs and PASS going forward.  I would also like to thank every one who encouraged me to reach beyond my comfort zone and accept a leadership position within the PASS organization.  My overall principle was to be a good steward of the PASS community.  Could I have done more?  Always. Did I do enough?  I hope so.  But PASS is a volunteer organization and my time, like yours, is limited.  I have other obligations in life that supersede PASS.  Now I have more time for some of those.  I won’t be going away or leaving the SQL Community.  I will still contribute to the community and support PASS, just in a different role.  Time to let somebody else enjoy the hot seat for a while. Finally, everyone who voted (not just for me) deserves a thanks.  More voters and more engaged voters, strong candidates, and a vigorous debate were all I wanted out of declaring as a candidate last year. This year the SQL community got exactly that. Thank you..

  • SQLRally Nordic gets underway

    - by Rob Farley
    PASS is becoming more international, which is great. The SQL Community has always been international – it’s not as if data is only generated in North America. And while it’s easy for organisations to have a North American focus, PASS is taking steps to become international. Regular readers will be aware that I’m one of three advisors to the PASS Board of Directors, with a focus on developing PASS as a more global organisation. With this in mind, it’s great that today is Day 1 of SQLRally Nordic, being hosted in in Sweden – not only a non-American country, but one that doesn’t have English as its major language. The event has been hosted by the amazing Johan Åhlén and Raoul Illyés, two guys who I met earlier this year, but the thing that amazes me is the incredible support that this event has from the SQL Community. It’s been sold out for a long time, and when you see the list of speakers, it’s not surprising. Some of the industry’s biggest names from Microsoft have turned up, including Mark Souza (who is also a PASS Director), Thomas Kejser and Tobias Thernström. Business Intelligence experts such as Jen Stirrup, Chris Webb, Peter Myers, Marco Russo and Alberto Ferrari are there, as are some of the most awarded SQL MVPs such as Itzik Ben-Gan, Aaron Bertrand and Kevin Kline. The sponsor list is also brilliant, with names such as HP, FusionIO, SQL Sentry, Quest and SolidQ complimented by Swedish companies like Cornerstone, Informator, B3IT and Addskills. As someone who is interested in PASS becoming global, I’m really excited to see this event happening, and I hope it’s a launch-pad into many other international events hosted by the SQL community. If you have the opportunity, thank Johan and Raoul for putting this event on, and the speakers and sponsors for helping support it. The noise from Twitter is that everything is going fantastically well, and everyone involved should be thoroughly congratulated! @rob_farley

  • Nvidia dual monitor configuration gets lost every time I reboot

    - by sunwukung
    I've recently updated (well, borked then completely reinstalled) to 12.04. I'm running a dual monitor setup, with a Dell U2410 / Dell 2007WFP combination on an HP Elite Book 8560W. The graphics card is an NVIDIA GF108 [Quadro 1000M]. My problem is as follows. I can get the dual monitor setup working fine, but every time I reboot, my machine appears to lose the settings (specifically, the U2410 is disabled, the mouse pointer is locked in the launcher). I have to restate the settings after every launch. I've tried running nvidia-settings as sudo, I've save the changes to my xorg.conf file (see below) but nothing seems to be sticking. Has anyone had similair issues, or know of a fix?

  • Using MVVM, how to pass SelectedItems of a XamDataGrid as parameter to the Command raised by the Co

    - by saddaypally
    Hi, I'm trying to pass the item on XamDataGrid on which I do a mouse right click to open a ContextMenu, which raises a Command in my ViewModel. Somehow the method that the Command calls is not reachable in debug mode. This is the snipped from the view <ig:XamDataGrid DataSource="{Binding DrdResults}" Height="700" Width="600"> <ig:XamDataGrid.ContextMenu> <ContextMenu DataContext="{Binding RelativeSource={RelativeSource Mode=Self}, Path=PlacementTarget.DataContext}" AllowDrop="True" Name="cmAudit"> <MenuItem Header="View History" Command="{Binding ViewTradeHistory}" CommandParameter="{Binding Path=SelectedItems}"> </MenuItem> </ContextMenu> </ig:XamDataGrid.ContextMenu> <ig:XamDataGrid.FieldSettings> <ig:FieldSettings AllowFixing="NearOrFar" AllowEdit="False" Width="auto" Height="auto" /> </ig:XamDataGrid.FieldSettings> </ig:XamDataGrid> My code in the corresponding ViewModel for this View is as follows public WPF.ICommand ViewTradeHistory { get { if (_viewTradeHistory == null) { _viewTradeHistory = new DelegateCommand( (object SelectedItems) = { this.OpenTradeHistory(SelectedItems); }); } return _viewTradeHistory; } } And lastly the actual method that gets called by the Command is as below private void OpenTradeHistory(object records) { DataPresenterBase.SelectedItemHolder auditRecords = (DataPresenterBase.SelectedItemHolder)records; // Do something with the auditRecords now. } I'm not sure what am I doing incorrectly here. Any help will be very much appreciated. Thanks, Shravan

  • How to pass a parameter to jQuery UI dialog event handler?

    - by bebraw
    I am currently trying to hook up jQuery UI dialog so that I may use it to create new items to my page and to modify ones existing already on the page. I managed in the former. I'm currently struggling in the latter problem, however. I just cannot find a nice way to pass the item to modify to the dialog. Here's some code to illustrate the issue better. Note especially the part marked with XXX. The {{}} parts are derived from Django template syntax: $(".exercise").click(function() { $.post("{{ request.path }}", { action: "create_dialog", exercise_name: $(this).text() }, function(data) { $("#modify_exercise").html(data.content); }, "json" ); $("#modify_exercise").dialog('open'); }); $("#modify_exercise").dialog({ autoOpen: false, resizable: false, modal: true, buttons: { '{% trans 'Modify' %}': function() { var $inputs = $('#modify_exercise :input'); var post_values = {}; $inputs.each(function() { post_values[this.name] = $(this).val(); }); post_values.action = 'validate_form'; //XXX: how to get the exercise name here? post_values.exercise_name = 'foobar'; $.post('{{ request.path }}', post_values, function(data) { if( data.status == 'invalid' ) { $('#modify_exercise').html(data.content); } else { location.reload(); } }, "json" ); } } }); Here's some markup to show how the code relates to the structure: <div id="modify_exercise" class="dialog" title="{% trans 'Modify exercise' %}"> </div> <ul> {% for exercise in exercises %} <li> <a class="exercise" href="#" title="{{ exercise.description }}"> {{ exercise.name }} </a> </li> {% endfor %} </ul>

  • How can I pass an arbitrary object to jasper report as parameter?

    - by spderosso
    Hi, I would like to pass as a parameter to my .jrxml an arbitrary object of my domain, e.g a Person. InputStream reportFile = MyPage.this.getClass().getResourceAsStream("test.jrxml"); HashMap<String, Person> parameters = new HashMap<String, Person>(); parameters.put("person", new Person("John", "Doe")); ... JasperReport report = JasperCompileManager.compileReport(reportFile); JasperPrint print = JasperFillManager.fillReport(report, parameters, new JREmptyDataSource()); return JasperExportManager.exportReportToPdf(print); And on the .jrxml do something like: <?xml version="1.0" encoding="UTF-8"?> <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="test" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20"> <property name="ireport.zoom" value="1.0"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <parameter name="PERSON" isForPrompting="false" class="myApp.domain.person"/> <background> <band splitType="Stretch"/> </background> <title> <band height="20"> <staticText> <reportElement x="180" y="0" width="200" height="20"/> <text><![CDATA[$P{PERSON.lastName}]]></text> </staticText> </band> </title> ... Is something like this possible? Where can I find more complex tutorials that show more than just passing a java.lang.String? Thanks

  • How do I pass a cookie to a Sinatra app using curl?

    - by Brandon Toone
    I'm using the code from the example titled "A Slightly Bigger Example" from this tutorial http://rubylearning.com/blog/2009/09/30/cookie-based-sessions-in-sinatra/ to figure out how to send a cookie to a Sinatra application but I can't figure out how to set the values correctly When I set the name to be "brandon" in the application it creates a cookie with a value of BAh7BiIJdXNlciIMYnJhbmRvbg%3D%3D%0A which is a url encoding (http://ostermiller.org/calc/encode.html) of the value BAh7BiIJdXNlciIMYnJhbmRvbg== Using that value I can send a cookie to the app correctly curl -b "rack.session=BAh7BiIJdXNlciIMYnJhbmRvbg==" localhost:9393 I'm pretty sure that value is a base64 encoding of the ruby hash for the session since the docs (http://rack.rubyforge.org/doc/classes/Rack/Session/Cookie.html) say The session is a Ruby Hash stored as base64 encoded marshalled data set to :key (default: rack.session). I thought that meant all I had to do was base64 encode {"user"=>"brandon"} and use it in the curl command. Unfortunately that creates a different value than BAh7BiIJdXNlciIMYnJhbmRvbg==. Next I tried taking the base64 encoded value and decoding it at various base64 decoders online but that results in strange characters (a box symbol and others) so I don't know how to recreate the value to even encode it. So my question is do you know what characters/format I need to get the proper base64 encoding and/or do you know of another way to pass a value using curl such that it will register as a proper cookie for a Sinatra app?

  • How do I pass data from a BroadcastReceiver through to an Activity being started?

    - by Tom Hume
    I've got an Android application which needs to be woken up sporadically throughout the day. To do this, I'm using the AlarmManager to set up a PendingIntent and have this trigger a BroadcastReceiver. This BroadcastReceiver then starts an Activity to bring the UI to the foreground. All of the above seems to work, in that the Activity launches itself correctly; but I'd like the BroadcastReceiver to notify the Activity that it was started by the alarm (as opposed to being started by the user). To do this I'm trying, from the onReceive() method of the BroadcastReceiver to set a variable in the extras bundle of the intent, thus: Intent i = new Intent(context, MyActivity.class); i.putExtra(wakeupKey, true); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(i); In the onResume() method of my Activity, I then look for the existence of this boolean variable: protected void onResume() { super.onResume(); String wakeupKey = "blah"; if (getIntent()!=null && getIntent().getExtras()!=null) Log.d("app", "onResume at " + System.currentTimeMillis() + ":" + getIntent().getExtras().getBoolean(wakeupKey)); else Log.d("app", "onResume at " + System.currentTimeMillis() + ": null"); } The getIntent().getExtras() call in onResume() always returns null - I don't seem to be able to pass any extras through at all in this bundle. If I use the same method to bind extras to the PendingIntent which triggers the BroadcastReceiver however, the extras come through just fine. Can anyone tell me what's different about passing a bundle from a BroadcastReceiver to an Activity, as opposed to passing the bundle from an Activity to a BroadcastReceiver? I fear I may be doing something very very obvious wrong here...

  • How do I pass arguments to pages in a WPF application?

    - by Rod
    I'm working on upgrading a really old VB6 app to a WPF application. This will be a page-based app, but not a XBAP. The old VB6 app had a start form where a user would enter search criteria. Then they would get results in a grid, select a row in the grid and then click on one of 3 buttons. I am thinking that what I'll do is use hyperlink controls on the WPF app. No matter what button the user clicked on the old VB6 app, it would go to a second form. What it did on the second form was dependent upon which button the user clicked on the first form. So, I want the first page in my WPF app to do the same thing, but depending upon which hyperlink they click on will dictate what happens on the second page. They will either (a) go to the second page to edit the details as well as a lot more information, related to what they selected on the first page, or (b) enter a new record and all associated data (a new client, in this case), or (c) create a new case for the same client, selected on the first page. For me the hard thing is I don't know how to pass that information along to the second page. Is there something in WPF like in HTML where there's a query string? Or how do you get information from the first page to the second page, in WPF? I'm working in VS 2008.

  • MYSQL Data -> PHP arrays -> Javascript (or Jquery) How can I pass the data with JSON ?

  • How do I pass a const reference in C#?

    - by Maciek
    In C++, passing const references is a common practice - for instance : #include <iostream> using namespace std; class X { public : X() {m_x = 0; } X(const int & x) {m_x = x; } X(const X & other) { *this = other; } X & operator = (const X & other) { m_x = other.m_x; return *this; } void print() { cout << m_x << endl; } private : int m_x; }; void main() { X x1(5); X x2(4); X x3(x2); x2 = x1; x1.print(); x2.print(); x3.print(); } This very simple example illustrates how it's done - pretty much. However I've noticed that in C# this doesn't seem to be the case. Do I have to pass const references in C# ? what do I need the "ref" keyword for? Please note that I know and understand what C# reference and value types are.

  • jQuery HOW TO?? pass additional parameters to success callback for $.ajax call ?

    - by dotnetgeek
    Hello jQuery Ninjas! I am trying, in vain it seems, to be able to pass additional parameters back to the success callback method that I have created for a successful ajax call. A little background. I have a page with a number of dynamically created textbox / selectbox pairs. Each pair having a dynamically assigned unique name such as name="unique-pair-1_txt-url" and name="unique-pair-1_selectBox" then the second pair has the same but the prefix is different. In an effort to reuse code, I have crafted the callback to take the data and a reference to the selectbox. However when the callback is fired the reference to the selectbox comes back as 'undefined'. I read here that it should be doable. I have even tried taking advantage of the 'context' option but still nothing. Here is the script block that I am trying to use: <script type="text/javascript" language="javascript"> $j = jQuery.noConflict(); function getImages(urlValue, selectBox) { $j.ajax({ type: "GET", url: $j(urlValue).val(), dataType: "jsonp", context: selectBox, success:function(data){ loadImagesInSelect(data, $j(this)) } , error:function (xhr, ajaxOptions, thrownError) { alert(xhr.status); alert(thrownError); } }); } function loadImagesInSelect(data, selectBox) { //var select = $j('[name=single_input.<?cs var:op_unique_name ?>.selImageList]'); var select = selectBox; select.empty(); $j(data).each(function() { var theValue = $j(this)[0]["@value"]; var theId = $j(this)[0]["@name"]; select.append("<option value='" + theId + "'>" + theValue + "</option>"); }); select.children(":first").attr("selected", true); } From what I have read, I feel I am close but I just cant put my finger on the missing link. Please help in your typical ninja stealthy ways. TIA

    - by sameer
    Here is my code: The jewellery class is my main class in which i am inheriting a connection string class. class Jewellery : Connectionstr { string lmcode; public string LM_code/**/Here i want to access the value of the method ReadData i.e displaystring and i want to store this value in the insert query below.** { get { return lmcode; } set { lmcode = value; } } string mname; public string M_Name { get { return mname; } set { mname = value; } } string desc; public string Desc { get { return desc; } set { desc = value; } } public string ReadData() { OleDbDataReader dr; string jid = string.Empty; string displayString = string.Empty; String query = "select max(LM_code)from Master_Accounts"; Datamanager.RunExecuteReader(Constr, query); if (dr.Read()) { jid = dr[0].ToString(); if (string.IsNullOrEmpty(jid)) { jid = "AM0000"; } int len = jid.Length; string split = jid.Substring(2, len - 2); int num = Convert.ToInt32(split); num++; displayString = jid.Substring(0, 2) + num.ToString("0000"); dr.Close(); } **return displayString;** I want to pass this value to the above property procedure above i.e LM_code. } public void add() { String query ="insert into Master_Accounts values ('" + LM_code + "','" + M_Name + "'," + "'" + Desc + "')"; Datamanager.RunExecuteNonQuery(Constr , query);// } If possible can u edit this code!

  • Is there a way to pass another parameter in the preg_replace_callback callback function?

    - by DaNieL
    mmmh guys, i really hope my english is good enaught to explain what i need. Lets take this example (that is just an example!) of code: class Something(){ public function Lower($string){ return strtolower($string); } } class Foo{ public $something; public $reg; public $string; public function __construct($reg, $string, $something){ $this->something = $something; $this->reg = $reg; $this->string = $string; } public function Replace(){ return preg_replace_callback($this->reg, 'Foo::Bar', $this->string); } public static function Bar($matches){ /* * [...] * do something with $matches and create the $output variable * [...] */ /* * I know is really useless in this example, but i need to have an istance to an object here * (in this example, the Something object, but can be something else!) */ return $this->something->Lower($output); } } $s = new Something(); $foo = new Foo($myregexp, $mystring, $s); $content = $foo->Replace(); So, the php manual say that to use a class method as callback in preg_replace_callback(), the method must be abstract. I need to pass an instance of a previuosly initialized object (in the example, an instance of the Something class) at the callback function. I tryed to use call_user_func(), but doesnt work (becose in this way i miss the matches parameter). Is there a way to do that, or have i to separate the process (doing before preg_match_all, for each match retrieve the replace value, and then a simple preg_replace)?

  • Why can't I pass an argument to create this window using wxpython?

    - by somefreakingguy
    I am trying to learn how to make a GUI in python! Following an online tutorial, I found that the following code 'works' in creating an empty window: import wx from sys import argv class bucky(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(300, 200)) if __name__=='__main__': app=wx.PySimpleApp() frame=bucky(parent=None,id=-1) frame.Show() app.MainLoop() That gives me a window, which is great. However, what if I want to get an argument passed onto the program to determine the window size? I thought something like this ought to do the trick: import wx from sys import argv script, x, y = argv class mywindow(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x, y)) if __name__=='__main__': app=wx.PySimpleApp() frame=mywindow(parent=None,id=-1) frame.Show() app.MainLoop() But, alas, that does not work! Nor does the raw_input() function pass on the value. I keep getting the following error: C:/Python26/pythonw.exe -u "C:/Documents and Settings/Owner/Desktop/wz.py" File "C:/Documents and Settings/Owner/Desktop/wz.py", line 8 wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x y)) ^ SyntaxError: invalid syntax Thanks for the help!
