  • Pass authentication between php and Ruby On Rails application

    - by Li
    Hi, I have a simple Ruby on rails application that I want to integrate with an existing php website. I only want that users who's been authenticated by the php application would have access to my Ruby on Rails application (it should appear to the user as the same website, in the same domain, though it can be a different sub-domain if I chose to) What's the best way to do that? Thanks for the help, Li

  • Limitations in running Ruby on windows7

    - by orkutscraps
    n the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows7, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself?

  • Converting upper-case string into title-case using Ruby

    - by wsb3383
    Hi, all. I'm trying to convert an all-uppercase string in Ruby into a lower case one, but with each word's first character being upper case. Example: convert "MY STRING HERE" to "My String Here". I know I can use the .downcase method, but that would make everything lower case ("my string here"). I'm scanning all lines in a file and doing this change, so is there a regular expression I can use through ruby to achieve this? Thanks!

  • Python/Ruby IDE (Windows)?

    - by Lee Tang
    Are there any Windows IDEs that support both Ruby and Python? I'm talking about the type of IDE that has syntax suggestions (auto-completion feature). I've tried Netbeans but it only seems to support Ruby (maybe there's a way to add Python support?)

  • Ruby on Rails Problem PotionStore

    - by David Schiefer
    Hello, I am trying to install the PotionStore on my Mac OS X 10.6 server with Ruby on Rails 3 installed. Upon launching the server on port 3000 and pointing safari to this address, I get this: NameError in Store/orderController#index uninitialized constant ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::PGconn What does this mean? I'm not too advanced with Ruby on Rails, so this throws me a bit.

  • What does @@variable mean in Ruby?

    - by Andrew
    What are Ruby variables preceded with double at signs (@@)? My understanding of a variable preceded with an at sign is that it is an instance variable, like this in PHP: PHP version class Person { public $name; public function setName($name) { $this->name = $name; } public function getName() { return $this->name; } } Ruby equivalent class Person def set_name(name) @name = name end def get_name() @name end end What does the double at sign @@ mean, and how does it differ from a single at sign?

  • Cross-platform embedded database/key-value store for C#

    - by Arne Claassen
    I'm looking for a fast, embeddable key/value store with cursor semantics over key collections (or a simple embeddable DB) that I can use in .NET and mono. Need it to be open-source, would prefer an MIT or Apache style license over a GPL license. Not opposed to a library that needs bindings to be written, as long as binaries are available for both windows and linux. Options considered: SQLite - has bindings and native implementation, but single-threaded and not all that fast Embedded InnoDB - no .NET bindings i can find and it's GPLv2 Berkley DB - no .NET bindings i can find Tokyo Cabinet - no .NET bindings i can find and problematic to build on windows MadCow Memory-mapped data structures - GPLv2 Is there an option better than the above that i'm missing, or bindings for the above i don't know about?

  • Embedded file system and sqlite

    - by Jeff Lamb
    I'm working on an embedded project that has no file system, and our kludge of a database has ballooned in functionality. It's now so inefficient, we can't stand it any longer. I'm trying to figure out if there's built-in support for a flat file system in SQLite. I've dug around http://sqlite.org for a while now, but haven't found anything specifically covering it. Has anyone found a supported implementation written in C? It seems like such a straightforward request, but I can't find anything written about it. We have plenty of memory available. In a perfect world, I'd like to just set aside a large portion of it, pass the FS a pointer, then let the FS/SQLite library just use what it wants.

  • Advantages of Thread pooling in embedded systems

    - by Microkernel
    I am looking at the advantages of threadpooling design pattern in Embedded systems. I have listed few advantages, please go through them, comment and please suggest any other possible advantages that I am missing. Scalability in systems like ucos-2 where there is limit on number of threads. Increasing capability of any task when necessary like Garbage collection (say in normal systems if garbage collection is running under one task, its not possible to speed it up, but in threadpooling we can easily speed it up). Can set limit on the max system load. Please suggest if I am missing anything.

  • Microsecond (or one ms) time resolution on an embedded device (Linux Kernel)

    - by ChrisDiRulli
    Hey guys, I have a kernel module I've built that requires at least 1 ms time resolution. I currently use do_gettimeofday() but I'm concerned that this won't work once I move my module to an embedded device. The device has a 180 Mz processor (MIPS) and the default HZ value in the kernel is 100. Thus using jiffies will only give me at best 10 ms resolution. That won't cut it. What I'd like to know is if do_gettimeofday() is based on the timer interrupt (HZ). Can it be guaranteed to provide at least 1 ms of resolution? Thanks!

  • Embedded Prolog Interpreter/Compiler for Java

    - by Sami
    I'm working on an application in Java, that needs to do some complex logic rule deductions as part of its functionality. I'd like to code my logic deductions in Prolog or some other logic/constraint programming language, instead of Java, as I believe the resulting code will be significantly simpler and more maintainable. I Googled for embedded Java implementations on Prolog, and found number of them, each with very little documentation. My (modest) selection criteria are: should be embeddable in Java (e.g. can be bundled up with my java package instead of requiring any native installations on external programs) simple interface to use from Java (for initiating deductions, inspecting results, and adding rules) come with at least a few examples on how to use it doesn't necessarely have to be Prolog, but other logic/constraint programming languages with the above criteria would suit my needs, too. What choices do I have and what are their advantages and disadvantages?

  • Create a new embedded language using PHP

    - by dino beytar
    I am trying to develop an administration panel and I have a command line. When a user send a command like below, i need to recognize it using PHP. My aim is simplifying tasks in the admin panel. create page -attr1 90 -attr2 'page title'; or update category 90 -name 'Technology'; There are two main things: Verb and subject (ie. create page, update category) Attributes (can be both STRING and INT) and more complex example: create page -name EN:'Static Page' CA:'Staticna Stranica' -category 3,6,12,15; Where can I start to create this very small embedded language, or how can I do it well really? Clever answers, please.

  • IAR Embedded Workbench - setting endian-ness of variable

    - by Seidleroni
    I'm using IAR Embedded Workbench for ARM (ARM7TDMI-S) and the majority of my work is done using little-endian format. However, I saw in the manual that I can do something like : __big_endian int i, j; to declare those two variables as big endian (while the rest of the app as little endian). This seems like a fantastic feature, but when I try to compile, I always get the errror: Error[Pa002]: the type attribute "__big_endian" is not allowed on this declaration. The big endian line above is copied directly from the manual, but it does not work. This is a great feature of the compiler and would make life a big easier. Any ideas how to get it working? I have my language conformance set to 'Allow IAR extensions' on the C/C++ Compiler options tab on the IDE options.

  • using Eclipse to develop for embedded Linux on a Windows host

    - by Travis
    I got a question of using Eclipse to develop for embedded Linux on a Windows host Here are now I have and where I am. 1. a Windows host that have the latest Eclipse + CDT (c/c++ development tools) installed 2. a Ubuntu host (ssh + samba installed) that contains sources and toolschain to build the project. (the windows and ubuntu hosts are sitting within one network segment (In LAN).) 3. I can use the following commands to build this project under Ubuntu. # chroot dummyroot # cd /home/project/Build # sh Build date +%Y%m%d%H%M%S 4. I am now trying to create an eclipse C++ project to achieve the goad of the step 3, but I have been stuck here for a while. any ideas of how it can be done?

  • Embedded MongoDB when running integration tests

    - by seanhodges
    My question is a variation of this one. Since my Java Web-app project requires a lot of read filters/queries and interfaces with tools like GridFS, I'm struggling to think of a sensible way to simulate MongoDB in the way the above solution suggests. Therefore, I'm considering running an embedded instance of MongoDB alongside my integration tests. I'd like it to start up automatically (either for each test or the whole suite), flush the database for every test, and shut down at the end. These tests might be run on development machines as well as the CI server, so my solution will also need to be portable. Can anyone with more knowledge on MongoDB help me get idea of the feasibility of this approach, and/or perhaps suggest any reading material that might help me get started? I'm also open to other suggestions people might have on how I could approach this problem...

  • Rapid Prototyping for Embedded Systems

    - by dr_pepper
    For doing prototyping on small embedded projects that require physical motion, what hardware prototyping tools are available? For my projects, I tend to spend more time finding parts (i.e. wood, aluminum, etc.) and making the proper cuts, measurements, and connections than writing the software and configuring the electrical hardware. Are there any affordable products that will enable me to create physical hardware that is strong enough to support motion? If not, what techniques or tools are available to help develop the physical hardware more quickly? Currently, I typically build my projects from wood and plastic scraps that I have lying around. What types of materials enable you to prototype more quickly? CLARIFICATION: By motion, I mean something that has to bear stress like a robot arm powered by a servo motor and could handle moving or carrying 1-2 lbs.

  • How to write configurable Embedded C code which can run on multihardware platform

    - by Adnan
    Hello all , What are the techniques used to write an embedded C software which has multi features. Features can be configurable for multi-hardware platform. I have developed a firmware based on a RTOS for ARM7. Now i want to make it a baseline firmware which can be used with similar, more or less features (configurable) on different microcontrollers, like MSP, or AVR etc. Being more specific, if i want to change different features of firmware for one hardware and others for the second. What technique should i adopt and is there any study material available. Regards

  • Connection to embedded device with Windows and .Net

    - by tim
    I am building a .net application(xp, vista, 7) that will communicate with an embedded device. I will be able to connect via IP, serial port and modem. Question: Should I allow some type of open connection within my application that will allow me to connect to the device through some other channels that may be set up in the operating system just to allow future extensibility without really having to change anything on the device? I was just imagining that the operating system would be able to serve all communication channels that may be setup through the operating system to the device. Like would an admin setup some channel through SMTP or other protocol. I just didn’t want to box myself in and ignore some more open architecture. Thanks.

  • Description format for an embedded structure

    - by praetorian20
    Hi, I have a C structure that allow users to configure options in an embedded system. Currently the GUI we use for this is custom written for every different version of this configuration structure. What I'd like for is to be able to describe the structure members in some format that can be read by the client configuration application, making it universal across all of our systems. I've experimented with describing the structure in XML and having the client read the file; this works in most cases except those where some of the fields have inter-dependencies. So the format that I use needs to have a way to specify these; for instance, member A must always be less than or equal to half of member B. Thanks in advance for your thoughts and suggestions.
