    - by Ke

I got through this tutorial http://www.howtoforge.com/installing-php-5.3-nginx-and-php-fpm-on-ubuntu-debian But I now get the following error: unknown directive "fastcgi_split_path_info" in /etc/nginx/sites-enabled/default:28 Anyone know what might be causing the problem?

  • Is it still cheaper to build your own PC?

    - by Jeff Yates
    With many companies offering build-to-order PCs, where they can source components at bulk purchase prices, is there any value in building your own PC. Is it still a good option for everyone or is it only cost-effective for those building fringe equipment like high spec gaming platforms? Don't forget to factor in the time and effort you spend building and configuring the machine. I know that it is often worthwhile as it builds understanding of your machine, gets you exactly what you want, etc., but is it still good for your wallet or would you be better off paying someone else to do it and spend more time doing something else?

  • Dynamic expression tree how to

    - by Savvas Sopiadis
    Hello everybody! Implemented a generic repository with several Methods. One of those is this: public IEnumerable<T> Find(Expression<Func<T, bool>> where) { return _objectSet.Where(where); } Given to be it is easy to call this like this: Expression<Func<Culture, bool>> whereClause = c => c.CultureId > 4 ; return cultureRepository.Find(whereClause).AsQueryable(); But now i see (realize) that this kind of quering is "limiting only to one criteria". What i would like to do is this: in the above example c is of type Culture. Culture has several properties like CultureId, Name, Displayname,... How would i express the following: CultureId 4 and Name.contains('de') and in another execution Name.contains('us') and Displayname.contains('ca') and .... Those queries should be created dynamically. I had a look in Expression trees (as i thought this to be a solution to my problem - btw i never used them before) but i cannot find anything which points to my requirement. How can this be costructed? Thanks in advance

  • Char and Chr in Delphi

    - by JamesB
    The difference between Chr and Char when used in converting types is that one is a function and the other is cast So: Char(66) = Chr(66) I don't think there is any performance difference (at least I've never noticed any, one probably calls the other).... I'm fairly sure someone will correct me on this! Which do you use in your code and why?

  • C# How can I trigger an event at a specific time of day?

    - by Andrei
    Hello everybody. I'm working on a program that will need to delete a folder (and then re-instantiate it) at a certain hour of the day, and this hour will be given by the user. The hour will most likely be during the night, because that's when nobody is accessing the folder (it's outside working hours). Is there a way to trigger that event at that certain hour? I know about timers, but is there an easier way to do this without a timer that ticks and checks to see what time it is? Thanks.

  • How can I concatenate multiple rows in a matrix

    - by Matthijs
    In Java I would like to concatenate an array (a[], fixed length) to an array of the same length, to create a matrix M[2][length of a]. This way I would like to subsequently paste more of those arrays onto the matrix. (Comparable to the Matlab vertcat function..C=[A;B]) Is this possible? Thanks

  • Does the List in .NET work the same way as arraylist in Java?

    - by eflles
    When I learned Java, I was told that the arraylist works this way: It creates an array with room for 10 elements. When the 11th element is added, it is created a new list with room for 20 elements, and the 10 elements are copied into the new array. This will repeat as until there are no more elements to add, or to a maximum size. Is the List in .NET constructed the same way?

  • Unnecessary code...

    - by Martin Milan
    Suppose I have some code that looks like this: Private Sub MySub() dim blnFlag as Boolean blnFlag = False for each item in collection if item.Name = "Mike" then blnFound = true exit for endif next item End Sub Now - the blnFLag = False assignment is not actually necessary - booleans are initialised as false, but I think it's inclusion makes the code easier to read. What's your opinion?

  • Example of moving from MySQL to NoSQL?

    - by OverTheRainbow
    Hello, For a Facebook-like site, ie. which is write-intensive and delivers user-customized pages, I'd like to build a prototype to investigate whether the document-centric NoSQL architecture would be a good alternative to sharding and reduce the load on the single master (+ multiple slaves) that we currently use and is the bottleneck. Does someone know of a good article that would give actual, simple examples of going from a relational layout in MySQL to a NoSQL layout? Thank you.

  • Thread-safe data structures

    - by Inso Reiges
    Hello, I have to design a data structure that is to be used in a multi-threaded environment. The basic API is simple: insert element, remove element, retrieve element, check that element exists. The structure's implementation uses implicit locking to guarantee the atomicity of a single API call. After i implemented this it became apparent, that what i really need is atomicity across several API calls. For example if a caller needs to check the existence of an element before trying to insert it he can't do that atomically even if each single API call is atomic: if(!data_structure.exists(element)) { data_structure.insert(element); } The example is somewhat awkward, but the basic point is that we can't trust the result of exists call anymore after we return from atomic context (the generated assembly clearly shows a minor chance of context switch between the two calls). What i currently have in mind to solve this is exposing the lock through the data structure's public API. This way clients will have to explicitly lock things, but at least they won't have to create their own locks. Is there a better commonly-known solution to these kinds of problems? And as long as we're at it, can you advise some good literature on thread-safe design? Thank you.

  • jQuery .get appends an unknown variable to URL

    - by ILMV
    I'm using this code as the starting point to an overhaul of our JavaScript framework: $("#get").click(function(){ $("#result").html(ajax_load); $.get( "http://www.google.com", {}, function(responseText){ $("#result").html(responseText); }, "html" ); }); But when the request is made it includes a variable within the URL that I am unfarmiliar with, here is what Firebug says it's requesting: http://www.google.com/?_=1268993359215 How do I get rid of this, when we target our internal scripts it's firing a 404 error :-( Cheers!

  • Get content of a single cell from a DataGrid in Flex 3

    - by Captain Phoenix
    I want to select information in a single cell from my DataGrid in Flex 3. Specifically, I'm displaying three phone numbers per line and the user needs to be able to select one of those numbers, from any row, but not the whole row. While similar to this, I am displaying the DataGrid to the user. The answer for that question was to manipulate the dataProvider, how can I know what cell I've selected in order to do that?

  • Subversion unable to merge changes when using Dreamweaver

    - by neilc
    I've got a project running and we're using SVN as the version control. There are 3 devs on it. Dev1 = OSX + Textmate Dev2 = Windows 7 + Dreamweaver (plus tortoise svn) Dev3 = OSX + Coda Case 1 (expected): Dev1 and dev3 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev3 updates their copy. signup.php is merged as expected. All good. Case 2 (not expected): Dev1 and dev2 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev2 updates their copy. signup.php is always in conflict even though different parts of the file are worked on. This is not the expected behaviour experienced by dev1 and dev3. This works boths ways and each time dev1 updates dev2's changes he gets conflicts too. But never with dev3. Could this be down the way Dreamweaver is saving files ? Perhaps character encoding. We are all working in UTF8. These constant and unnecessary conflicts are becoming a massive distraction. Help !

  • Best practice to maintain source code under version control with multiple companies?

    - by lastcosmonaut
    Hey, I'm wondering if there is any best practice for maintaining your source code under version control among different companies. In Open Source there is a maintainer, who receives patches, decides on them and applies them. But what about closed sourced projects where different companies get different workloads and just commit them to the trunk and branches? Is this maintainer concept applicable to a project on which multiple companies work on?

  • How to disable dragging from a Rich Edit Control

    - by John
    I use a subclass of CRichEditCtrl to provide a CEdit+ type control. One thing I want is to disable drag-drop functionality, which the base class provided by default. Disabling dropping is easy: ::RevokeDragDrop(m_hWnd); But I can't see a simple way to disable the control being a drag-source. Is there an easy way?

  • POCO Best Practice

    - by Paul Johnson
    All, I have a series of domain objects (project is NHibernate based). Currently as per 'good practice' they define only the business objects, comprising properties and methods specific to each objects function within the domain. However one of the objects has a requirement to send an SMTP message. I have a simple SMTP client class defined in a separate 'Utilities' assembly. In order to use this mail client from within the POCO, I would need to hold a reference to the utilities assembly in the domain. My query is this... Is it a departure from best practice to hold such a reference in a POCO, for the purpose of gaining necessary business functionality. Kind Regards Paul J.
