  • La Maison-Blanche fait de l'open source et publie sa première application sur GitHub, We The People est sous Drupal et MongoDB

    La Maison-Blanche fait de l'open source Et publie sa première application sur GitHub, We The People est sous Drupal et MongoDB C'est une première. La Maison-Blanche vient de distribuer la première application open source créée par un gouvernement, disponible dans son dépôt GitHub officiel. Il s'agit d'une application permettant à tout citoyen de créer, voter et faire voter une pétition. C'est le code même qui propulse l'application « We The People » (nous le peuple) qu'on retrouve sur le site de la Maison-Blanche. C'est en fait la concrétisation d'un engagement pris par le président Barack Obama en septembre 2011 : « Parmi nos engagements, nous sommes en train de lancer un out...

  • How to create a view to manage associations between HABTM models? (Rails)

    - by Chris Hart
    Hello, I am using Ruby on Rails and need to create a view that allows the creation of records through a HABTM relationship to another model. Specifically, I have the following models: Customer and ServiceOverride, and a join table customers_serviceoverrides. Using the customer view for create/update, I need to be able to create, update and delete ServiceOverrides and manage the attributes of the associated model(s) from the same view. Visually I'd prefer to have something like a plus/minus sign to add/delete service overrides, and each serviceoverride record has two string entities which need to be displayed and editable as well. However, if I could just get the code (a kind of nested form, I'm assuming?) working, I could work out the UI aspects. The models are pretty simple: class ServiceOverride < ActiveRecord::Base has_and_belongs_to_many :customers end class Customer < ActiveRecord::Base has_and_belongs_to_many :serviceoverrides end The closest thing I've found explaining this online is on this blog but it doesn't really address what I'm trying to do (both manage the linkages to the other model, and edit attributes of that model. Any help is appreciated. Thanks in advance. Chris

  • manage.py runserver throws an ImportError with my appname, MacPorts issue on OSX?

    - by christmasgorilla
    I've been developing a Django app for weeks locally on OSX 10.6.3. Recently, I rebooted my machine and went to start my development environment up. Here's the error: cm:myApp cm$ python manage.py runserver Traceback (most recent call last): File "manage.py", line 11, in execute_manager(settings) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 360, in execute_manager setup_environ(settings_mod) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 343, in setup_environ project_module = import_module(project_name) File "/Library/Python/2.6/site-packages/django/utils/importlib.py", line 35, in import_module import(name) ImportError: No module named myapp I'm pretty new to Django / Python. Digging around, it's possible that this might be due to MacPorts. Initially, I had a rough time getting Django up and running and I no longer remember if I'm using the Django from a MacPorts install or from easy_install. How do I tell? (I'd prefer not to reinstall everything). Also, why is the camel casing in my app name gone in the ImportError message? When I search for "myapp" in my django project, I don't find it without camelcase anywhere. And what causes MacPorts to work for a while but then break? As a few other details, from settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', 'south', 'registration', 'pypaypal', 'notifier', 'myApp.batches', )

  • How to organize and manage multiple database credentials in application?

    - by Polaris878
    Okay, so I'm designing a stand-alone web service (using RestLET as my framework). My application is divided in to 3 layers: Data Layer (just above the database, provides APIs for connecting to/querying database, and a database object) Object layer (responsible for serialization from the data layer... provides objects which the client layer can use without worrying about database) Client layer (This layer is the RestLET web service... basically just creates objects from the object layer and fulfills webservice request) Now, for each object I create in the object layer, I want to use different credentials (so I can sandbox each object...). The object layer should not know the exact credentials (IE the login/pw/DB URL etc). What would be the best way to manage this? I'm thinking that I should have a super class Database object in my data layer... and each subclass will contain the required log-in information... this way my object layer can just go Database db = new SubDatabase(); and then continue using that database. On the client level, they would just be able to go ItemCollection items = new ItemCollection(); and have no idea/control over the database that gets connected. I'm asking this because I am trying to make my platform extensible, so that others can easily create services off of my platform. If anyone has any experience with these architectural problems or how to manage this sort of thing I'd appreciate any insight or advice... Feel free to ask questions if this is confusing. Thanks! My platform is Java, the REST framework I'm using is RestLET, my database is MySQL.

  • How can I manage building library projects that produce both a static lib and a dll?

    - by Scott Langham
    I've got a large visual studio solution with ~50 projects. There are configurations for StaticDebug, StaticRelease, Debug and Release. Some libraries are needed in both dll and static lib form. To get them, we rebuild the solution with a different configuration. The Configuration Manager window is used to setup which projects need to build in which flavours, static lib, dynamic dll or both. This can by quite tricky to manage and it's a bit annoying to have to build the solution multiple times and select the configurations in the right order. Static versions need building before non-static versions. I'm wondering, instead of this current scheme, might it be simpler to manage if, for the projects I needed to produce both a static lib and dynamc dll, I created two projects. Eg: CoreLib CoreDll I could either make both of these projects reference all the same files and build them twice, or I'm wondering, would it be possible to build CoreLib and then get CoreDll to link it to generate the dll? I guess my question is, do you have any advice on how to structure your projects in this kind of situation? Thanks.

  • Which browser does my computer use to open a Web page? [on hold]

    - by msh210
    I know little about networking the Internet, but, from what I understand, it works — very approximately — as follows: I, sitting at the computer example.com, send a message saying, roughly, "get http://s.tk" to my ISP, which passes the message along, eventually to the machine at s.tk. The s.tk machine gets "example.comhas sent 'gethttp://s.tk'", so sendssomefileto its ISP which passes the file along, eventually to the machine atexample.com`. When the file gets back to example.com, my computer, how does my computer know what to do with it? I'm sure the headers (or something else) indicate it's a Web page rather than, say, a Usenet post — that's not my question. My question is: how does it know whether to display the Web page in my open Opera window or my open Firefox window, or my other open Firefox window, or, heck, to open a new browser instance?

  • Since upgrading to Windows 8.1, I can't open any files on a SMB share shared by my OS X Mavericks Mac

    - by Gary
    I have a PC with Windows 8.1 and a Mac with Mavericks. I have a folder on the Mac that is shared with the PC. When I'm on the PC and I try to open a file that is shared by the Mac, such as an ISO file (a disk image), then I get a message saying that I cannot open the file, or the file is in use (it depends on the app/filetype). I have the same problem when I open a video file. Strangely, text files and PDF files are just fine. And if I copy any of the problematic files to the local Windows disk, then I can open them just fine. The specific error messages are: AVI files opened in VLC: "Your input can't be opened. VLC is unable to open the MRL." ISO files opened by Windows Explorer: "Sorry, there was a problem mounting the file." This only started happening after I upgraded to Windows 8.1 on the PC and Mavericks on the Mac. Mavericks upgraded its SMB version from SMB1 to SMB2, so perhaps that is related? Does anyone know what the problem might be, and how I could fix it? Thanks in advance!

  • How do you duplicate current open Finder view in new tab (Mavericks)?

    - by magoo
    In a thread on this forum there is an interesting solution on how to open a duplicate of an already open Finder window with the help of an AppleScript: How do you duplicate current open Finder view? With the new tabbed Finder in OS X 10.9 Mavericks, I am wondering if there is a way to implement an AppleScript that opens the duplicate in a new Finder tab instead of a new Finder window? Did anybody succeed in finding a solution?

  • How can I configure firefox to open links in the same window, but requests from external application

    - by Mnementh
    I hate it, when sites decide for me, which links should open in a new window, and which in the same. The back-button doesn't work. Good thing is, firefox has the option browser.link.open_newwindow. If I set this to 1, all links with target=blank open in the same window, as it should be. But now also clicks in external programs (like the email-client or newsreader) on links open this in the same window, destroying the already opened website. How can I configure firefox to open links in a website always in the same window, but in external programs opened URLs always in a new one?

  • How can I restore "Open With" context menu item in Windows 7?

    - by Izzy Helianthus
    I tried various way to fix this problem but ended up with a dead end. My problem would be the missing "Open With" context menu items (or subitems?). It did not appear even though I hovered it for a minutes or two. Below is a screenshot of the respective right-click menu. Note: The only problem with "Open With" is at the right-click menu (as well as FILE menu). Edited: The "Open With" context submenu that only accessible at the top, while the typical right click menu doesn't work. Repaste from Comment. I don't think it's involved with any windows files because other user in the same computer doesn't affected at all. I can see the "Open With" context submenu. I believe this must have involved with current user's registry. It happens to all files (any file types, except folder). I can only use Open With by clicking at the file and select it manually at the top of Explorer window. (Refer to the link for the screenshot)

  • How to know currently open ports on the Windows Firewall?

    - by QIU Quan
    On Windows XP and Windows Server 2003, I can know currently open ports on the Windows Firewall using the following command: netsh firewall show state However, on Windows 7 and Hyper-V Server 2008 R2, when I give that command, it says: No ports are currently open on all network interfaces. IMPORTANT: Command executed successfully. However, "netsh firewall" is deprecated; use "netsh advfirewall firewall" instead. Apparently there are ports open because services such as NetBIOS NS, Remote Desktop, and Hyper-V remote administration are functioning. I tried a few 'netsh advfirewall' show commands, but didn't get a way to find out which ports are permit by Windows Firewall. Knowing the currently open ports, I can be sure that I'm permitting necessary and sufficient traffic to pass in, no more, no less. Going through the whole set of advanced firewall rules is so tedious and error-prone. Is there a command on Windows 7 and Windows Server 2008 to do this efficiently?

  • Is it possible to open Adobe Illustrator files from last close?

    - by ksy
    Say you have three files open in Adobe Illustrator, but you exit out of the program. Is there a way that you can have those three files opened back up when you open up Illustrator again? Similar to how most text editor programs are set up -- so when you open up the program again all your last stayed-open files are there. Also, does anyone know what the terminology for this saving-behavior is? State-saving? Googling to find the answer is difficult within the sea of Illustrator 'saving files' questions.

  • How to open first n bytes of file in hexadecimal and edit it?

    - by Larssend
    I want to edit some .avi videos (cut them, to be precise) in VirtualDub but it failed to open the files. They are encoded in xvid, which I have installed, and play in KMPlayer without problem. Also, all other xvid videos can be opened and cut just fine by VirtualDub. I suspect there's something wrong in the first few bytes of these particular videos (the magic number?). This means I have to open the offending files in a hex editor and make some necessary adjustments to the header. Problem is, they are very large ( 3 GB each) and take very long time to open in UltraEdit. Can UltraEdit open just the first few bytes of a file? If not, do you know of an application that can do that? Edit: I'm using Windows XP.

  • Windows Photo Viewer can't open this picture because you don't have the correct permissions to access the file location

    - by Software Monkey
    My system in Windows 7 and fully up to date with all patches and options (except for Microsoft Silverlight, which I refuse to install). I get this error whenever I try to open an image using Windows Photo Viewer, such as when previewing from Explorer or when opening an image attachment to an email. I have already verified correct permissions to the file and all folders in the path. The strange thing is that every other program I have seems to open the images fine, including "Slideshow" from Windows Explorer. Even more strange, in WPV there is an "Open" menu that lists the other programs for images including GIMP and MS Paint and they open the very file that WPV is complaining about just fine. That should eliminate permissions as being the problem, especially since (logically at least) they are read/write while WPV is read-only. I have even edited and saved the images that WPV does not open. I am out of ideas, and searching for answer on the Web has resulted only in the same tired repitition of some flavor of "take ownership and reset permissions for the entire drive", which I have already done. And which is counter-indicated by the fact that only Windows Photo Viewer seems to have a problem. The one thing which is slightly unusual is that for normal files they are all on a second HDD mounted into C:, however for email attachments the temporary folder is C:\Temp\, which is directly on that drive.

  • nagios: trouble using check_smtps command

    - by ethrbunny
    I'm trying to use this command to check on port 587 for my postfix server. Using nmap -P0 mail.server.com I see this: Starting Nmap 5.51 ( http://nmap.org ) at 2013-11-04 05:01 PST Nmap scan report for mail.server.com (xx.xx.xx.xx) Host is up (0.0016s latency). rDNS record for xx.xx.xx.xx: another.server.com Not shown: 990 closed ports PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp 110/tcp open pop3 111/tcp open rpcbind 143/tcp open imap 465/tcp open smtps 587/tcp open submission 993/tcp open imaps 995/tcp open pop3s 5666/tcp open nrpe So I know the relevant ports for smtps (465 or 587) are open.

  • Can I rename a file that is open on Windows XP?

    - by Radek
    I want to programatically rename a file and it could be open. It's a log file. When I was testing my code the rename part didn't work because the log file TestPro.log was open by the TAF (Test Automation Framework). When TestPro is running and I try to delete the file I get the error "Cannot delete because is being used by another person or program." Is there any way how to rename a file (programatically) that is open the way the log file was?

  • How to stop iPhone's safari browser from silently dropping tabs when you open a 9th tab?

    - by MattH
    Currently in the iPhone safari mobile browser, if you have 8 tabs open and open a new tab, the new tab opens as requested, but one of the existing tabs is silently discarded. Is there any known way to change this behaviour, e.g. to prompt me first and allow me to choose which tab to close, or to open the 9th tab, or to at least have visibility of what tab was closed? When I open something in a new tab it's because I want to come back to the previous tab later, so this conflicts with the way I usually browse the web. My current workaround is to manually monitor the tab count -- i.e. to check that the count is 7 or less before opening a new tab.

  • Is there a way to force/manage file locking in windows?

    - by JPbuntu
    I have a 2 Windows machines networked and I am having trouble with simultaneous access to files. I would like only one user to be able to open a file at a time, which I thought was automatic, using file locks.... if the program used to access the file is locking the file. I believe the problem I am having is some of the programs I use, don't lock the file, and there for can be modified simultaneously by multiple users, which is very much not desired. Currently I am having this problem with only two computers, although as soon as I can figure out a solution to this problem the network is going to be expanded to 6 computers, which will include Windows 7, Vista, and XP, as well as a central file server (Samba). Is there a way to ensure that all files opened in windows get locked? Any suggestions are appreciated, thanks.

  • What are your favorite open source tools? (that is not very famous)

    - by sucuri
    I believe every system administrator is used to open source by now. From Apache to Firefox or Linux, everyone uses it at least a little bit. However, most open source developers are not good in marketing, so I know that there are hundreds of very good tools out there that very few people know. To fill this gap, share your favorite open source tool that you use on your day by day that is not very famous. *I will post mine in the comments.

  • How can I open a shared sub calendar in Outlook 2010?

    - by Matt Love
    There is a team in my office that has a shared calendar (the team calendar is set up as a user in Active Directory/Exchange, so treat the team as a user). The team also has 3 sub-calendars for the different team members. Other people in the office need to be able to access this team's calendar. They can go to Open Calendar in Outlook and see the main calendar, but they cannot see the sub-calendars. The sub-calendars all have the Default user permissions set to Reviewer. If you go to File → Account Settings → Change [logged in Exchange account] → More Settings → Advanced and add the team's mailbox, it does show the calendars in Outlook, but it comes up under My Calendars instead of Shared Calendars. We need to be able to go to Open Calendar and open the calendar and open all the sub-calendars this way. How is this possible?

  • Add a right click context menu in certain WIndows folders that will open a web browser URL?

    - by jasondavis
    In a Windows Explorer window where you browse files in Windows 7, I would like to add a new context menu that will allow me to open a file on my local Dev Server. So it would have to open a browser like Google Crome and the URL would have to be the file path but slightly different removing part of it and prepending my localhost URL. For example if the file I am right clicking on, the path for that file might be... E:\Server\htdocs\labs\php\testProject\test.php I would need a button to click in the context menu Open in Browser and it would open my Web Browser with a URL like this... http://localhost/labs/php/testProject/test.php I would love to be able to do this, any ideas or help would greatly be appreciated! To go one step further, would to be able to somehow make the context menu item only show up on File that are under this folder.... ``E:\Server\htdocs` but this is far less important.

  • Safari: how to re-open MULTIPLE previously closed tabs?

    - by courteous
    CMD + Z in Safari (6.0.1) will re-open the last closed tab. Is there any way to re-open multiple previously closed tabs (as in, say, Chrome)? A closely related question from 2011: Are there any extensions or tricks to reopen several closed tabs in Safari Update Safari is now at 6.0.2: having the ability to re-open multiple closed tabs would still very much improve usability (i.e. not having to go searching the History). Is the answer still "impossible"?
