  • Ruby open-uri open method loses file extension opening images

    - by Jimmy
    I'm using ruby 1.9.2 along with Rails 3.1.4 and Paperclip 2.4.5. My issue is trying to save a paperclip attachment from a URI loses the file extension and saves the file without one resulting in issues with things like fancybox that require an extension. Some example code: uri = "http://featherfiles.aviary.com/2012-06-13/bbe5f0de1/0c5a672b88ea47ecb4631ac173e27430.png" open(uri) #=> #<File:/var/folders/zc/d69gxhzx10x_bvjrkqgyjgxr0000gn/T/open-uri20120613-27204-i6cldv> Because there is no extension on the temp file paperclip is saving the file without one resulting in issues. Has anyone run into this issue? I've seen multiple answers about using paperclip to store images from a URI but none seem to address the same problem we're running

  • How to open different App version for one given file extension

    - by Erik Lenaerts
    We have a data files with an extension ".ppx" for our business app here. Users will typically have multiple versions of the application installed (side by side) for example version 1 and version 2. The ppx files are xml files and they contain the version of the app they were created from (v1 or v2). Lets say that we have AFileCreatedWithAppv1.ppx and AFileCreatedWithAppv2.ppx opens with version 1 or version 2 of our app respectivly when they both have the same file extension? It must be doable since that is what Visual Studio does. In fact, they even provide different icons for the same .sln extension to indicate what Visual Studio version it will open with. I learned that Visual Studio is using the Selector or Launcher in between, but then again, how do they change the icons in Windows? cheers :)

  • OpenSSL: SessionTicket TLS extension problem

    - by rursw1
    Hello, I'm using an application which uses OpenSSL for client TLS side. We upgrade the OpenSSL version from 0.9.8e to 0.9.8k. And then TLS doesn't work... Wireshark shows that the new version (with OpenSSL 0.9.8k) sends the client hello packet with a SessionTicket extension - and the server side responds with a fatal internal error. The previous version sends an almost identical hello packet, but without the SessionTicket ext. When I replaced TLSv1_client_method with SSLv23_client_method, everything worked fine - the sent client hello packet was a SSLv2 one (In the sniffer) without any extension (as it wasn't TLS but SSL?) Is there a better way to disable this extension or to solve the problem in another way? Thanks in advance, rursw1

  • Running a packaged exe in the same folder as the installed firefox extension

    - by mustafabar
    I have read this thread, and some other How to run a local exe in my firefox extension The problem is, at deployment and using firefox 4.0.1, if I install the .xpi extension, the xpi is put inside the \Profiles...\extensions as **.xpi, which is a compressed format All the solutions assume that the the extension is put in a folder, thus they are accessing the folder as is, which I cannot do for example this guy says //**** get profile folder path **** var dsprops = Components.classes['@mozilla.org/file/directory_service;1'] .getService(Components.interfaces.nsIProperties); var ProfilePath = dsprops.get("ProfD", Components.interfaces.nsIFile).path; //**** initialize file **** var file = Components.classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile); file.initWithPath(ProfilePath); //**** append each step in the path **** file.append("extensions"); file.append("guid"); file.append("sample.exe"); guid in my case is installed as {f13b157f-b174-47e7-a34d-4815ddfdfeb8}.xpi which cannot be accessible this way

  • Using wget to save sequential files as well as renaming the file extension

    - by Ian
    I run a cron job that requests a snapshot from a remote webcam at a local address: wget http://user:[email protected]/snapshot.cgi This creates the files snapshot.cgi, snapshot.cgi.1, snapshot.cgi.2, each time it's run. My desired result would be for the file to be named similar to file.1.jpg, file.2.jpg. Basically, sequentially or date/time named files with the correct file extension instead of .cgi. Any ideas?

  • Print the file name with another extension (Batch-program)

    - by Semyon Perepelitsa
    Batch-program launchs with 1 parameter (full path to file) program.cmd "C:\Path\To\File\Filename.txt" Now, this program consists of 1 command: echo %1 And it just prints an argument: C:\Path\To\File\Filename.txt for the upper example. But I want it to print an argument (full path) with another extension, e.g. .exe. For the upper example, I want it to print C:\Path\To\File\Filename.exe. How to make it do that?

  • Code optimizer extension for Dreamweaver?

    - by Vercas
    Due to my neat coding style, my pages take up like 30% more space on both my server and the output HTML. Is there any free extension for Dreamweaver to automatically optimize my pages when uploading them? I mean not only HTML, but also PHP, CSS and JS... Actually, removing unnecessary tabs, spaces and new lines will just do the trick. After removing the unnecessary spaces, tabs and new lines from my PHP code, the page loaded three times faster so this is important...

  • alternative to download them all extension for firefox

    - by Nrew
    Do you know of any good alternative for the firefox extension download them all. Because when I try to download the second time(after the first has been downloaded) in megaupload. There would be a temporary error, which is not really temporary. Because it will last until you clean the cache/history.

  • Setting objects (not users) inactive after period of time in asp.net mvc

    - by bastijn
    This question is mainly to verify my current idea. I have a series of objects which I want to be active for a specified amount of time. For instance objects like ads which are shown in the ad space only for the amount of time bought, objects in search results which should only pop up when active, and frontpage posts which should be set to inactive after a prespecified time. My current idea is to just give those type of objects a StartDate and EndDate and filter the search routines to only show results which fall in the range StartDate < currentDate < EndDate. Is this the normal structure or should there be some sort of auto-routine which routinely checks for objects which are "over-time" and set a property "inactive" to true or something. Seems like this approach is such a hassle since I need a checker which runs say, every 5 minutes, to scan all DB objects. Seems like a bad idea to me. So is the first structure the most commonly used or are there any other options? When searching on google or SO the search queries only return results setting users inactive.

  • Splitting a set of object into several subsets of 'similar' objects

    - by doublep
    Suppose I have a set of objects, S. There is an algorithm f that, given a set S builds certain data structure D on it: f(S) = D. If S is large and/or contains vastly different objects, D becomes large, to the point of being unusable (i.e. not fitting in allotted memory). To overcome this, I split S into several non-intersecting subsets: S = S1 + S2 + ... + Sn and build Di for each subset. Using n structures is less efficient than using one, but at least this way I can fit into memory constraints. Since size of f(S) grows faster than S itself, combined size of Di is much less than size of D. However, it is still desirable to reduce n, i.e. the number of subsets; or reduce the combined size of Di. For this, I need to split S in such a way that each Si contains "similar" objects, because then f will produce a smaller output structure if input objects are "similar enough" to each other. The problems is that while "similarity" of objects in S and size of f(S) do correlate, there is no way to compute the latter other than just evaluating f(S), and f is not quite fast. Algorithm I have currently is to iteratively add each next object from S into one of Si, so that this results in the least possible (at this stage) increase in combined Di size: for x in S: i = such i that size(f(Si + {x})) - size(f(Si)) is min Si = Si + {x} This gives practically useful results, but certainly pretty far from optimum (i.e. the minimal possible combined size). Also, this is slow. To speed up somewhat, I compute size(f(Si + {x})) - size(f(Si)) only for those i where x is "similar enough" to objects already in Si. Is there any standard approach to such kinds of problems? I know of branch and bounds algorithm family, but it cannot be applied here because it would be prohibitively slow. My guess is that it is simply not possible to compute optimal distribution of S into Si in reasonable time. But is there some common iteratively improving algorithm?
