  • Nobody owner (99 99) in FTP caused by php functions !

    - by hacen
    I have a script (Joomla) that creates files and directories on the server. The problem is that it creates them under owner 99 99 (nobody) and after I can't delete or modify them by FTP without the help of the server admin. I think that is move_uploaded_file function of php. Is there any solution of this problem by the WHM or by the server admin? Can I modify the default owner in ftp?

  • Security of executing a command from php

    - by Nicolò Martini
    I'm writing a web application in which i use several thirdy party commands calling them with the exec function in PHP (for example, I render Latex formulas through a command-line program). My question is: what are the security issues of executing external command-line programs in php? What I have to be aware of? Can you give me a list of points to check? Thanks in advance.

  • Rails: three most recent comments with unique users

    - by Dennis Collective
    what would I put in the named scope :by_unique_users so that I can do Comment.recent.by_unique_users.limit(3), and only get one comment per user? class User has_many :comments end class Comment belongs_to :user named_scope :recent, :order => 'comments.created_at DESC' named_scope :limit, lambda { |limit| {:limit => limit}} named_scope :by_unique_users end on sqlite named_scope :by_unique_user, :group = "user_id" works, but makes it freak out on postgres, which is deployed on production PGError: ERROR: column "comments.id" must appear in the GROUP BY clause or be used in an aggregate function

  • How to catch 'exceptions' for out of order execution in Workflow Foundation 4?

    - by Alex Key
    Hi, I am attempting to model a worklfow using a "WCF Workflow Service" in .net / vs 2010 that needs to handle out of order execution gracefully (but not allow it - if thath makes sense!?) For example I have 2 receive activities one called Initialize and the other called GetValue inside a FlowChart. In most cases Initialize should be called first and GetValue after (as modled in the flow chart). However if GetValue is executed before Initialize I do not want to return an "out of order" exception (although when I look at the WCF test client, I can't actually see an exception). But instead a custom exception saying something like "you must initialize first". In theory I could model this with lots of parallel activities and conditions to check if Initialized / Running / Terminated etc. But the business process I am modelling if very very similar to a state machine... except it must handle people executing things in the wrong order. Ideally I would like to catch the "out of order" exception (thought I don't think it's really an exception as such), check the 'exception' to see which function was attempted to run and then handle it. I have done some research around enabling AllowBufferedReceive. However I don't want to be able to execute out of order (I don't think), but instead give a detailed response if it does happen. I've looked at the new beta state machine template for WF 4 - but i'm not sure if it does what i'm after? I'm not sure if I have the wrong end of the stick, so any help would be greatly appreciated. [EDIT] To help clarify... Sorry it's a tricky one to explain. The standard I am trying to implement (the e-learning standard SCORM RTE) is structured like a state machine i.e. certain functions can only be executed in certain states. However the standard specifies that if the calling clients tries to execute a function that it is not meant to, then a warning should be issued... for example "you cannot use GetValue(), because you have not yet Initialized". Ideally I'd like to structure the workflow as the theoretical state machine and not need to have to use multiple if/else's to handle all the scenarios where something could be executed out-of-order. I'd like to catch a out-of-order exception (but I don't think there is such an exception - as it's not in the debugger) and rethrow it.

  • Copy call signature to decorator

    - by Morgoth
    If I do the following def mydecorator(f): def wrapper(*args, **kwargs): f(*args, **kwargs) wrapper.__doc__ = f.__doc__ wrapper.__name__ = f.__name__ return wrapper @mydecorator def myfunction(a,b,c): '''My docstring''' pass And then type help myfunction, I get: Help on function myfunction in module __main__: myfunction(*args, **kwargs) My docstring So the name and docstring are correctly copied over. Is there a way to also copy over the actual call signature, in this case (a, b, c)?

  • WPF: Can I use VisualStateManager to change alignment?

    - by kennethkryger
    Hi, I've got this "object-stack" - Window --- Grid (VerticalAlignment = Stretch) ----- Border (VerticalAlignment = Stretch OR Top) The Border a primitive UserControl right now to keep things simple for me. I'd like to be able to use the VisualStateManager to toggle the VerticalAlignment-property of the Border, so that the "Normal-state" equals VerticalAlignment.Top and "Expanded-state" equals VerticalAlignment.Stretch. Is this possible? Also, I'd like to use an easing function, when swithing between the two states.

  • How to tell whether a font is monospace using GTK and Pango?

    - by ptomato
    I have a PangoFontDescription and I want to know whether it describes a monospace font. I have seen the function pango_font_family_is_monospace() in the Pango API documentation but after several hours of puzzling it is still not clear to me what the relationships are between PangoFontFamily, PangoFontMap, PangoFont, PangoFontset, PangoContext, and PangoFontDescription and whether I need any or all of these to achieve what I want. So far, PangoFontDescription is the only part of Pango I've needed to use, as GTK manages to abstract everything else away. Can anyone who has done this before help me out?

  • programmatically unset a default application

    - by dystroy
    I made a Home application and I'd like to offer the ability to exit it and unset it as the default application. Exit is easy (just starting an intent) but the problem is I don't want my program to be launched again the next time the user click the Home button. I know that this can be done by going in the parameters / Applications / my app / erase default actions but I would like to do it from my program so that the user doesn't have to search this function. How can it be done ?

  • Great programming quotes

    - by epatel
    There are a lot of great programming quotes out there. Which do you like? Today (Sept 12, 2008) I heard a new one from a friend, Lars-Gunnar, he said "Gud finns i Emacs" (in Swedish). This basically means "God is in Emacs". Still laughing about it here :) What he meant was that a function "gud is grand-unified-debugger" is in Emacs. A great one I think all programmers should know is The Three Great Virtues of a Programmer.

  • PHP Echo a large block of text

    - by Thomas
    Im new to PHP and I can't figure out what the rules are for using the echo function. For example, if I need to echo a large block of css/js, do I need to add echo to each line of text or is there a way to echo a large block of code with a single echo? When I try to echo a big block of code like this one, I get an error: if (is_single()) { echo '<link type="text/css" rel="stylesheet" href="http://jotform.com/css/styles/form.css"/><style type="text/css"> .form-label{ width:150px !important; } .form-label-left{ width:150px !important; } .form-line{ padding:10px; } .form-label-right{ width:150px !important; } body, html{ margin:0; padding:0; background:false; } .form-all{ margin:0px auto; padding-top:20px; width:650px !important; color:Black; font-family:Verdana; font-size:12px; } </style> <link href="http://jotform.com/css/calendarview.css" rel="stylesheet" type="text/css" /> <script src="http://jotform.com/js/prototype.js" type="text/javascript"></script> <script src="http://jotform.com/js/protoplus.js" type="text/javascript"></script> <script src="http://jotform.com/js/protoplus-ui.js" type="text/javascript"></script> <script src="http://jotform.com/js/jotform.js?v3" type="text/javascript"></script> <script src="http://jotform.com/js/location.js" type="text/javascript"></script> <script src="http://jotform.com/js/calendarview.js" type="text/javascript"></script> <script type="text/javascript"> JotForm.init(function(){ $('input_6').hint('ex: [email protected]'); }); </script>'; }else { } Is there a better way to echo large blocks of code without a lot of work (adding echo to each line for example)?

  • Sanity check on this idea for an Image Viewer in a web app

    - by Charlie Flowers
    I have an approach in mind for an image viewer in a web app, and want to get a sanity check and any thoughts you stackoverflowers might have. Here's the whirlwind nutshell summary: I'm working on an ASP.NET MVC application that will run in my company's retail stores. Even though it is a web application, we own the store machines and have control over them. We have a "windows agent" running on the store machine which we can talk to via http post (it is a WCF service, and our web app has permission to talk to it from the browser). One of the web pages needs to be an "image viewer" page with some common things like Rotate & Zoom. Now, there are some WebForms controls that offer Rotate and Zoom. However, they take up server resources and generate a good bit of traffic between the server and the browser. For example, the Rotate function would cause an ajax call to the server, which would then generate a new image written to a .NET Canvas object, which would then be written to a file on the server, which would then be returned from the ajax call and refreshed inside the browser. Normally, that's a pretty good way of doing things. But in our case, we have code running on the store machine that we can communicate with. This leads me to consider the following approach: When the user asks to view an image, we tell our "windows agent" to download it from our image server to the store machine. We then redirect our browser to our image viewer page, which will pull the image from the local file we just wrote to the store machine. When the user clicks "Rotate", we cause JavaScript code in the browser to call our "windows agent" software, asking it to perform the "Rotate" function. The "windows agent" does the rotation using the same kind of imaging control that would formerly have been used on the server, but it does so now on the store machine. Javascript in the browser then refreshes the image on the page to show the newly rotated image. Zoom and similar features would be implemented the same way. This seems to be much more efficient, scalable, and responsive for the end-users. However, I've never heard of anything like it being done, mostly because it's rare to have this combination of a web app plus a "windows agent" on the client machine. What do you think? Feasible? Reasonable? Any pitfalls I overlooked or improvements / suggestions you can see? Has anyone done anything like this who would like to offer the wisdom of experience? Thanks!
