  • How can I configure apigee to fail stale if the backend is unavialble?

    - by Anurag Kapur
    We have an API proxy configured with cache ttl of 2mins. Is it possible to configure apigee to serve stale cached content if the backend goes down so that our end users don't see errors? We would rather have our end users get copies of stale cached content (even after the configured ttl of 2mins expires) instead of errors when the backend goes down. Would appreciate if someone could point me to the relevant documentation if this is possible.

  • How to save the world from your computer?

    - by Francisco Garcia
    Sometimes I miss the "help other people" factor within computer related careers. Sure that out there I could find many great projects improving society, but that is not common. However there are little things that we all can do to make this a better place beyond trying to erradicate annoynig stuff such as Visual Basic. You could join a cloud computing network such as World Community Grid to fight cancer. Write a charityware application such as Vim, improve an office IT infrastructure to support telecommuting and reduce CO2 emissions, use an ebook reader for saving paper... what else would you? which projects do you think can have an impact?

  • Java, JavaCC: How to check if a char (or char pair) is inside a given UTF32 range?

    - by java.is.for.desktop
    Hello, everyone! I am referring to the XML 1.1 spec. Look at the definition of NameStartChar: NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF] If I interpret this correctly, the last range (#x10000-#xEFFFF) goes beyond the UTF16 range of Java's char type. So it must be UTF32, right? So, I need to check pairs of char against this range, instead of single chars, right? My questions are: How do I check for such character ranges using standard Java methods? How is it possible to define such ranges in JavaCC? JavaCC complains about \u10000 and \uEFFFF Thank you! NOTE: Don't worry, I am not trying to write an own XML-parser. I need those character ranges for other reasons.

  • How would you create a notification system like on SO or Facebook in RoR?

    - by Justin Meltzer
    I'm thinking that notifications would be it's own resource and have a has_many, through relationship with the user model with a join table representing the associations. A user having many notifications is obvious, and then a notification would have many users because there would be a number of standardized notifications (a commenting notification, a following notification etc.) that would be associated with many users. Beyond this setup, I'm unsure how to trigger the creation of notifications based on certain events in your application. I'm also a little unsure of how I'd need to set up routing - would it be it's own separate resource or nested in the user resource? I'd find it very helpful if someone could expand on this. Lastly, ajax polling would likely improve such a feature. There's probably some things I'm missing, so please fill this out so that it is a good general resource.

  • Asp.Net Impersonation Fails On First Try But Succeeds on Second

    - by KevDog
    We are using RDLC's in a Asp.net web application. For reasons beyond our understanding, the first call to the database server fails with the following error: An error has occurred during report processing. Cannot open database "TryParkingIt2" requested by the login. The login failed. Login failed for user 'EXTRANET\OurServerNameHere$'. Run the report again, it works. Huh? Update Click the button the first time, it fails. Click the button again, it works. The account being impersonated is a domain account.

  • Using USB PS2 hand controller in C#.NET

    - by rross
    I'm attempting to create a program that takes input from a usb ps2 hand controller, translate and passes the info to a rs232 device. I already have everything working for the rs232 device. The problem is interfacing with a usb controller. There doesn't seem to be any good documentation out there and on top of that .NET3.0/3.5 doesn't have any libs to help you out. How would one even get started?

  • How does Symfony pass members set in an action to a template?

    - by Martin Chatterton
    How does a member set inside an action... $this->foo = 'bar'; ...become a variable accessible from a template... echo $foo; // bar I would like to know how it is achieved at a framework level. There is a lot of documentation on how to use Symfony, but I've not managed to find much about how it all fits together behind the scenes (class structure/inheritance etc). Thanks in advance for your help!

  • How to install new modes in emacs 23 on OS X?

    - by estanford
    I just downloaded the Haskell and J modes off of SourceForge, and I'm having trouble figuring out how to make them interface with emacs 23. Google searches yield detailed instructions for emacs 22, but it looks like changes have been made that make it hard to figure out where I'm supposed to stick the binaries. The internal documentation seems to assume more experience with emacs internals than I currently have, and the problem has resisted solution for several days. Does anyone know how to get these modes up and running?

  • .Net regex: what is the word character \w?

    - by tanascius
    Simple question: What is the pattern for the word character \w in c#, .net? My first thought was that it matches [A-Za-z0-9_] and the documentation tells me: Character class Description Pattern Matches \w Matches any \w "I", "D", "A", "1", "3" word character. in "ID A1.3" which is not very helpful. And \w seems to match äöü, too. What else? Is there a better (exact) definition available?

  • Should I cast variables that use a typdef'd type?

    - by mesorismo
    If I have something like: typedef int MyType; is it good practice to cast the operands of an operation if I do something like this: int x = 5; int y = 6; MyType a = (MyType)(x + y); I know that I don't need to do that but wondering if it's better for intent/documentation/readability concerns.

  • How do you programmatically move the caret of a Flex TextArea to the end?

    - by Akinwale
    I'm trying to move the caret in a Flex TextArea to the end after appending some text from my code. I've looked through the reference documentation for TextArea and its underlying TextField but it appears there is no method provided to handle this. One approach I've tried is to set focus to the text area and dispatch a KeyUp KeyboardEvent with the event's key code set to the "End" key, but this doesn't work. Any ideas on how to do this? Thanks.

  • Unit testing with serialization mock objects in C++

    - by lhumongous
    Greetings, I'm fairly new to TDD and ran across a unit test that I'm not entirely sure how to address. Basically, I'm testing a couple of legacy class methods which read/write a binary stream to a file. The class functions take a serializable object as a parameter, which handles the actual reading/writing to the file. For testing this, I was thinking that I would need a serialization mock object that I would pass to this function. My initial thought was to have the mock object hold onto a (char*) which would dynamically allocate memory and memcpy the data. However, it seems like the mock object might be doing too much work, and might be beyond the scope of this particular test. Is my initial approach correct, or can anyone think of another way of correctly testing this? Thanks!

  • Passing a hostname of over 255 characters to getaddrinfo causes a getaddrinfo failed: memory allocat

    - by darrickc
    I am currently upgrading our software to support ipv6 and in the meantime I'm expanding hostname/ip fields to the max hostname size. In sun documentation it seems like this can be up to 1025 (netdb.h:#define NI_MAXHOST 1025 - this is the recommended hostname allocation define), but when I pass a hostname of over 255 to getaddrinfo I get "getaddrinfo failed: memory allocation failure". I am testing on a Sol10 box. Ideas?

  • can some one give me a sample gzip code for htaccess?

    - by Haroldo
    I'm keen to get started experimenting with gzip, but like i used to find php.net when i first started learning php, the apache documentation confuses me a bit. http://httpd.apache.org/docs/2.0/mod/mod_deflate.html I'd really appreciate a sample htaccess file to have a look at if anyone's got one? Also are there things which should be changed in the htconf file instead of htaccess if I'm enabling gzipping server-wide? Sorry i'm a newb with apache!

  • What is the "proper" method for determining if a swf is running within an AIR application?

    - by Michael Prescott
    I've got a Flex Web project and a Flex AIR project that use a common code-base. The common code defines several run-time loaded Flex Modules. I want the Flex Modules to behave differently depending on whether the running base application is WEB or AIR. What is the proper method for determining from the module code whether the module is running in a WEB or AIR application? (I found that Security.sandboxType.toString() returns "application", but I haven't found anything better in the documentation, yet.)

  • make script output link to code in Visual Studio

    - by JoelFan
    I sometimes need to search code for patterns in a way that goes beyond the regex capabilities of Visual Studio (e.g. patterns that depend on what was seen previously in the file or on the contents of other files). So I use Perl to analyze the source and output matching lines, along with the file name and line number. Since this is the exact same format as is produced by the search feature of Visual Studio, I wonder if there is a way to duplicate the functionality where I can double-click on a line and it will display that line in context in Visual Studio. Any ideas?

  • Which jQuery/css menu library for working with ASP.NET TreeView or Menu controls.

    - by ProfK
    I'm looking for a good jQuery or CSS, or combo, library to enance my left side menu in an an intranet application. I don't like the 'hover only' expand/collapse style of the ASP.NET Menu control on its own, and I don't like the 'icon-click only' expand/collapse style of the TreeView control on its own. I plan on trying the CSS Control Adapters, to render the menu with some self-respect, i.e. as nested <ul> or <ol> elements instead of the usual orgy of tables. Beyond that, I need something to give a bit of style and menulike behaviour to these nested lists, and I would prefer a jQuery plugin for this. Which should I use?

  • remove a varchar2 string from the middle of table data values

    - by Michelle Daniel
    Data in the file_name field of the generation table should be an assigned number, then _01, _02, or _03, etc. and then .ldf (example 82617_01.pdf). Somewhere, the program is putting a state name and sometimes a date/time stamp, between the assigned number and the 01, 02, etc. (82617_ALABAMA_01.pdf or 19998_MAINE_07-31-2010_11-05-59_AM.pdf or 5485325_OREGON_01.pdf for example). We would like to develop an SQL statement to find the bad file names and fix them. In theory it seems rather simple to find file_names that include a varchar2 data type and remove it, but putting the statement together is beyond me. Any help or suggestions apprecuiated. Something like ........... UPDATE GENERATION SET FILE_NAME (?) WHERE FILE_NAME (?...LIKE '%STRING%');?

  • Receiving Text From Another Application

    - by Garry
    Hi, I'm building some home automation software with Cocoa/Objective-C. The main application will have a minimal GUI and will most likely be represented by a status bar icon only. I'm using proprietary speech-to-text software (MacSpeech Dictate) that takes my voice command and converts it to plain text. I then need to send this plain text to my app for parsing. Is there a way to send a string to a Cocoa application? Could AppleScript achieve this? How would I make the NSString string in my app "available" to receive the passed string? For reasons that are beyond the scope of this question - it is not possible to dictate the command directly into my app. Many thanks in advance,
