  • What is the best language to use for building a fulfillment engine [on hold]

    - by John Stapleton
    I asked this on stack overflow and was suggested to move it here. I do understand it is a matter of opinion which is exactly what I aim to achieve here... I wanted to know what you think is the best language to write a fulfillment engine in? I cannot provide much detail but I am trying to build a control interface for servers and i wanted to build a program daemon that would process data on the authoritative server and the slave servers( the backbone of the network) with their own daemons running would check regularly(every 5 minutes or so) with the authoritative server and process the commands(securely) I am trying to build this with a minimal footprint(cpu and ram wise for the slaves, authoritative is going to be scalable) and to make it automated so that the user does not have to configure the daemon(installation is automated by the authoritative server) I am leaning away from my usual php set up for simplicity sake. Edit: I am not an expert in any particular language but flexible enough and willing to learn another.

  • Plans for Certifying Oracle Database 12c with E-Business Suite

    - by Steven Chan (Oracle Development)
    The Oracle Database 12c is now officially released.  We're as excited about this new database release as you are.  In fact, we've been testing a wide variety of E-Business Suite releases and configurations with internal DB 12c betas for some time.  This testing is going well, but as usual, Oracle's Revenue Recognition rules prohibit us from discussing certification and release dates You're welcome to monitor or subscribe to this blog. I'll post updates here as soon as soon as they're available.

  • How to make an object move again after being stopped by collision in Unity?

    - by Matthew Underwood
    I have a player object which position is always centered on the main camera's viewport. This object has a Rigidbody 2D, a box and circle collider. The player moves around a level, the level has a polygon collider attached. I move the camera until the object hits against the collider, which stops the movement of the camera by setting its speed to 0. The problem happens when I want to move the camera / player object away from the collider. As the speed is already at 0, it cannot move away from the collider. The script attached to the player object, checks for collisions and applies the speed to 0 on the main camera's test script. using UnityEngine; using System.Collections; public class move : MonoBehaviour { public float speed; public test testing; // Use this for initialization void Start () { speed = 10F; testing = Camera.main.GetComponent<test>(); } // Update is called once per frame void FixedUpdate () { Vector3 p = Camera.main.ViewportToWorldPoint(new Vector3(0.5F, 0.5F, Camera.main.nearClipPlane)); transform.position = new Vector3(p.x, p.y, -1); } void OnCollisionEnter2D(Collision2D col) { testing.speed = 0; } void OnCollisionExit2D(Collision2D col) { testing.speed = 10F; } } This is the script attached to the main camera; just a simple script that changes the camera's position. using UnityEngine; using System.Collections; public class test : MonoBehaviour { public float speed; public float translationY; public float translationX; // Use this for initialization void Start () { speed = 10F; } void FixedUpdate () { translationY = Input.GetAxis("Vertical") * speed * Time.deltaTime; translationX = Input.GetAxis("Horizontal") * speed * Time.deltaTime; transform.Translate(translationX, translationY, 0); } } The player object isn't kinematic and is a fixed angle, the colliders aren't triggers and the polygon collider isn't a trigger either. The player is the red square, the collider is the pink area. -- EDIT -- From the latest change the collider set up for the player So if the X speed was disabled. It wouldnt move into the side of the polygon colider which is good, but yet you couldnt move away from it. And moving down would move inside the colider.

  • IPS Package Groups

    - by Alan_Solaris_RE
    IPS group packages consist solely of dependencies on other packages that make up a logical grouping of software. These are similar to, but not the equivalent of, Solaris 10 metaclusters. The main difference is that metaclusters are nested subsets ranging from a minimal install to nearly all packages on the media. Group packages have no such hierarchy. They can overlap other groups, or be completely disjoint sets. A group dependency is set this way in an IPS package manifest file: depend fmri=full/pkg/name type=group Current Solaris Groups Solaris currently has 4 system groups defined. These are used for different types of installation, and are included in the xml manifest files used by the various Solaris installers: Package Name Summary Description Default Installation For:  group/system/solaris-desktop Oracle Solaris Desktop Provides an Oracle Solaris desktop environment Live Media  group/system/solaris-large-server Oracle Solaris Large Server Provides an Oracle Solaris large server environment Text Installer  group/system/solaris-small-server Oracle Solaris Small Server Provides a useful command-line Oracle Solaris environment  Zones  group/system/solaris-auto-install  Oracle Solaris Automated Installer Client  Provides an Oracle Solaris Automated Installer client  Automated Installer There are also several "feature" groups such as AMP and GNU Developer Tools. These are provided for convenience, but are not used directly by any installers. Retrieving Group Package Information A listing of all current groups can be found with the command: pkg info -r group/* A listing of all the packages in a group can be obtained with: pkg contents -o fmri -H -rt depend -a type=group groupname An example: $ pkg contents -o fmri -H -rt depend -a type=group solaris-desktop archiver/gnu-tar audio/audio-utilities codec/flac codec/libtheora codec/ogg-vorbis codec/speex communication/im/pidgin etc. You can determine which package group is currently installed on your system: $ pkg list group/system/\* Output would look like: NAME (PUBLISHER) VERSION IFO group/system/solaris-desktop 0.5.11-0.175.0.0.0.0.0 i-- Note that there are not version numbers associated with a group package dependency. The package version that best fits the system will be used, based on other dependencies such as what is listed in incorporation files. Installing a Group To Install a group, simple use the group package name as you would any other package: $ pkg install solaris-small-server  If you want to exclude a package from installing, you can use the --reject flag: $ pkg install --reject audio/audio-utilities solaris-desktop Creating Your Own Group To create your own group package, you can follow the pkg(5) documentation on how to create a package, and use this action for each package that is part of your group:   depend fmri=full/pkg/name type=group

  • What does private cloud Daas or DBaaS really mean ?

    - by llaszews
    Just had meeting with Fortune 1000 company regarding their private DBaaS or DaaS offering. Interesting to see what DBaaS really means to them: 1. Automated Database provisioning - Being able to 'one button' provision databases and database objects. This includings creating the database instance, creating database objects, network configuration and security provisioning. It is estimated that just being able to provision a new DB table in automated fashion will reduce time required to create a new DB table from 60 hours down to 8 hours. 2. Virtualization and blades - DBaaS infrastructure is all based upon VMs and blades. 3. Consolidation of database vendors - Moving from over ten database vendors down to three.

  • VLAN issues between linux kernels 2.6 / 3.3 in an ESX / Cisco environment

    - by David Griffith
    I shall attempt to explain an issue I have encountered - I have a VM running on esx 4.1 with an interface connected to VLAN800 via an access port on a cisco 3750. It runs linux - kernel 2.6.24, and has about 5 to 10 Mbit of chatter on 10.10.0.0/16 and various multicast addresses to look after. I needed to isolate certain devices from certain other devices on the network, with all of them having to talk to that one VM. No, the address space can't be separated, nor can the networks be easily vlan'd apart. The software on the VM listens to one interface only. Private vlans appear to be the way to go. So as a test, I built a bridge on the VM that globs together the vlans as needed. All good, everything works as expected. But occasionally (sigh) there's some latency that trips up a couple of profinet devices on the network because, you know, you're not really supposed to trunk real-time protocols around the place willy-nilly. I shift it to our test/backup server - works nicely, but I don't want it to be running on the test server as we muck around with that a lot. So I says to myself, "I'll put it on a new VM for testing and tweaking." I download a small linux distro with kernel 3.3, and install as a new VM with a the vlans as separate interfaces for testing. I power up the testing VM - ok. I bring up all the separate interfaces - ok. I can ping the production VM, see all sorts of traffic going past with tshark, etc. I build a bridge and put the primary vlan on it - the production VM running 2.6 immediately loses its multicast traffic - Unicast is fine. (?) I shut down the bridge - still no multicast traffic (!?) I power-cycle the production VM(!?!?) - multicast traffic returns. I trunk everything into the testing VM and create vlan interfaces under linux instead - same result, as soon as I start the bridge.... no multicast on the production VM. Ok, so I take a break and leave things alone. I decide to play with a couple of ubiquiti bullet radios - I'm testing various firmware as a side project. I flash a radio with Open-wrt-12.09. I enable a trunk on a port on a cisco on our network so I can muck around with multiple vlans and SSIDs I power up the radio and connect - ok. I create a vlan interface from the trunk.... the same vlan as the production VM wayyyyy over there, three cisco routers away. Ok. I bridge the vlan interface to the wifi interface and immediately get a phone call. The production VM has (suprise!) lost its multicast traffic. Again, nothing comes back until I power-cycle the VM. What the hell is going on?

  • Which version of Debian are Ubuntu LTS releases based on?

    - by barnac1e
    This answer says: The base of the operating system, Debian, comes in three versions: Stable, Testing and Unstable. Normally, Ubuntu is based on Testing; the LTS releases are based on Stable. That cannot be true then for 12.04 because Debian Stable (Squeeze) is almost going to be old-stable, and it's obvious that the kernel versions in 12.04, packages, etc. cannot have come from Debian Squeeze. So then what other Debian Stable is there for Precise to be based on?

  • C/C++ canonicaliser?

    - by A T
    Are there any C/C++ automated canonicallisers? - Something like astyle but which makes your code more concise, rather than formats it? For example, to go from: float foo() { float a; float b; a = 9455.34; b = 3543.8; return a*b; } int main(void) { float b; b = foo(); return 0; } To: float foo(); // Automated prototype creation int main(void) { float b = foo(); return 0; } float foo() { return 9455.34*3543.8; } (this is my coding style FYI: to reduce the lines-of-code without sacrificing readability)

  • Synchronizing Mysql Table Schema [on hold]

    - by user1122069
    I have some difficulty keeping track of my SQL changes in a text file in SVN. One solution that I am aware of is to put the SQL queries in files (1.sql, 2.sql...) and to manually load each file at the proper time. Besides missing commas, the process is too cumbersome when builds become more frequent. I have actually taken to asking a co-worker to send me his SQL changes on Skype and we just apply the changes immediately on our local, development, and production servers (using three PhpMyAdmin tabs). I have seen several GUI tools mentioned in similar questions on SO, but these are actually more work and less automated than the aforementioned methods. Is there any standardized process by which this is done in an automated way? I can only guess that large companies build their own mechanisms of keeping track of database schema changes (yet I can't find a word about it - maybe they use files?). This question was closed as off-topic on Stack Overflow, so I am re-posting it here.

  • Load Test Manifesto

    - by jchang
    Load testing used to be a standard part of the software development, but not anymore. Now people express a preference for assessing performance on the production system. There is a lack of confidence that a load test reflects what will actually happen in production. In essence, it has become accepted that the value of load testing is not worth the cost and time, and perhaps whether there is any value at all. The main problem is the load test plan criteria – excessive focus on perceived importance...(read more)

  • Is Running programs by address common?

    - by dgood1
    I have read some of the things posted here and I keep reading about people running stuff like /foldername/executable -cmd NAME (was reading about a programmer using Eclipse, so he was testing something he made) I don't see things like that when I run things here (Ubuntu 12.04) because of the launcher and the Ubuntu button at the very top. That and Eclipse indigo has a button for running and testing things it makes. Just asking how and why it's common? (assuming it's the Terminal[Ctrl+alt+T] but I'm not sure)

  • Puppet Decentralized Setup

    - by paul.tw
    I want to migrate my existing Puppet setup from master/client to a decentralized solution. I know other solutions, such as Ansible are easier to setup for that purpose, but I really want to stay with Puppet. I found "supply_drop"(https://github.com/pitluga/supply_drop) on github, so I followed the instructions and did the following: rvm gemset create testing rvm use 1.9.3@testing gem install supply_drop The output is the following: [m@ms-MacBook-Pro:~ $ irb 1.9.3-p547 :001 require 'supply_drop' NameError: uninitialized constant Capistrano from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop/tasks.rb:1:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop.rb:10:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `rescue in require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:144:in `require' from (irb):1 from /Users/m/.rvm/rubies/ruby-1.9.3-p547/bin/irb:12:in `' Since that doesn't work without problems, I was wondering which alternatives are there available to do the same. Do you have any suggestings?

  • Windows7 corrupted profile - prevention exists?

    - by Radek
    I have dedicated Windows7 (not on domain) virtual machine for overnight automation testing. Some commands (mySQLdump, tscon.exe) must be run under administrator account. Last week administrator account's profile was corrupted. I fixed it by renaming it in the registry and logging in as administrator. And today it is corrupted again. I use administrator account only to run above commands via runas. Also the computer is restarted via cmd - shutdown command - quite often. Especially every night before automation testing starts. I checked the comp for viruses - did full scan using avast although I believed that the comp is clean. Any idea how to prevent the profile to get corrupted again? update So the first log entry in event log is today from 1.15am and one of my scripts ran runas command as administrator exactly at 1.15am. It was second time that runas war executed though after the testing started. The same happened second day in a row. Before the testing starts I need to copy one file that is locked. So I run handle.exe from runas to unlock it. That is what I think causing the profile to get corrupted. I am not able to reproduce it by myself. The message from event viewer is Windows cannot load the locally stored profile. Possible causes of this error include insufficient security rights or a corrupt local profile. DETAIL – The process cannot access the file because it is being used by another process.

  • Business Case for investing time developing Stubs and BizUnit Tests

    - by charlie.mott
    I was recently in a position where I had to justify why effort should be spent developing Stubbed Integration Tests for BizTalk solutions. These tests are usually developed using the BizUnit framework. I assumed that most seasoned BizTalk developers would consider this best practice. Even though Microsoft suggest use of BizUnit on MSDN, I've not found a single site listing the justifications for investing time writing stubs and BizUnit tests. Stubs Stubs should be developed to isolate your development team from external dependencies. This is described by Michael Stephenson here. Failing to do this can result in the following problems: In contract-first scenarios, the external system interface will have been defined.  But the interface may not have been setup or even developed yet for the BizTalk developers to work with. By the time you open the target location to see the data BizTalk has sent, it may have been swept away. If you are relying on the UI of the target system to see the data BizTalk has sent, what do you do if it fails to arrive? It may take time for the data to be processed or it may be scheduled to be processed later. Learning how to use the source\target systems and investigations into where things go wrong in these systems will slow down the BizTalk development effort. By the time the data is visible in a UI it may have undergone further transformations. In larger development teams working together, do you all use the same source and target instances. How do you know which data was created by whose tests? How do you know which event log error message are whose?  Another developer may have “cleaned up” your data. It is harder to write BizUnit tests that clean up the data\logs after each test run. What if your B2B partners' source or target system cannot support the sort of testing you want to do. They may not even have a development or test instance that you can work with. Their single test instance may be used by the SIT\UAT teams. There may be licencing costs of setting up an instances of the external system. The stubs I like to use are generic stubs that can accept\return any message type.  Usually I need to create one per protocol. They should be driven by BizUnit steps to: validates the data received; and select a response messages (or error response). Once built, they can be re-used for many integration tests and from project to project. I’m not saying that developers should never test against a real instance.  Every so often, you still need to connect to real developer or test instances of the source and target endpoints\services. The interface developers may ask you to send them some data to see if everything still works.  Or you might want some messages sent to BizTalk to get confidence that everything still works beyond BizTalk. Tests Automated “Stubbed Integration Tests” are usually built using the BizUnit framework. These facilitate testing of the entire integration process from source stub to target stub. It will ensure that all of the BizTalk components are configured together correctly to meet all the requirements. More fine grained unit testing of individual BizTalk components is still encouraged.  But BizUnit provides much the easiest way to test some components types (e.g. Orchestrations). Using BizUnit with the Behaviour Driven Development approach described by Mike Stephenson delivers the following benefits: source: http://biztalkbddsample.codeplex.com – Video 1. Requirements can be easily defined using Given/When/Then Requirements are close to the code so easier to manage as features and scenarios Requirements are defined in domain language The feature files can be used as part of the documentation The documentation is accurate to the build of code and can be published with a release The scenarios are effective to document the scenarios and are not over excessive The scenarios are maintained with the code There’s an abstraction between the intention and implementation of tests making them easier to understand The requirements drive the testing These same tests can also be used to drive load testing as described here. If you don't do this ... If you don't follow the above “Stubbed Integration Tests” approach, the developer will need to manually trigger the tests. This has the following risks: Developers are unlikely to check all the scenarios each time and all the expected conditions each time. After the developer leaves, these manual test steps may be lost. What test scenarios are there?  What test messages did they use for each scenario? There is no mechanism to prove adequate test coverage. A test team may attempt to automate integration test scenarios in a test environment through the triggering of tests from a source system UI. If this is a replacement for BizUnit tests, then this carries the following risks: It moves the tests downstream, so problems will be found later in the process. Testers may not check all the expected conditions within the BizTalk infrastructure such as: event logs, suspended messages, etc. These automated tests may also get in the way of manual tests run on these environments.

The code is all C++ but fairly complex. I'm looking for a way to automated / semi-automated generation of equivalent Makefiles out of my Xcode projects, after getting tired to do this by manual trial-and-error. Thanks for any hints.

  • QuickBuild: How can I create a builder to open a tarball package (tar.gz) whose name will change wit

    - by Jin Kim
    I'm using PMEase QuickBuild to perform automated builds of our Maven2 projects and a nightly sanity test to ensure nothing is broken. The test needs to untar packages which are created by the automated Maven2 projects. The problem is that the package names change frequently due to project versions being incremented all the time. Does anyone know how I can configure QuickBuild to pick up the version (ideally from the POM file of the individual components), if this is possible at all?

  • How can I limit the number of registrants to an event?

    - by user356900
    I've set up a basic html/php submission form where people can register for our event, but need a way to replace the submission form webpage with one that reads something like "We have reached our registration limit" when we reach a certain number of submitted forms. Our database is MySQL (if that makes a difference) I've looked around on the web but people either say to count the entries by hand, or the ones that do have an automated system use CMS like drupal or joomla. Is it possible to setup an automated script that will do this?

  • Hardware asset management systems

    - by Dave
    I need to track a bunch of specialized testing tools, They are hardware devices used for testing other equipement. Each device has a serial number and is sent out for use in testing. Occasionally they break and have to be sent to the manufacture for repair. I'm looking for an open source application (preferably a webapp) to help manage them. Right now we're using Excel and it's not scaling as we get more tools. They aren't computers so all the standard IT asset management systems don't really fit the bill. I found h-harmony, but that project seems dead?

  • Mobile Phone Browser Emulators/Simulators

    - by Jessie
    I work in QA in a .NET shop and recently part of my testing process has started to involve testing our company website on mobile devices. At least one of our techs uses an HTC Desire. After tons of googling I still can't find a good online emulator for testing websites on different types of mobile devices. Is anyone aware of a website that I can test across multiple mobile platforms? Or even an online HTC or Blackberry browser emulator? I've found an iphone/opera mini simulator, but that's about it. Also, I realize there are a lot of SDK's that include emulators, but I'd rather not have to set up an entire SDK just to use an emulator.

  • Asterisk does not recognise DTMF tones from mobile phones

    - by Eugene van der Merwe
    We have an Asterisk 1.8.7.0 (the Elastix derivative) switchboard. Every since a month ago, seemingly out of the blue, the switchboard does not recognise DTMF tones any more from mobile phones. Testing the switchboard using 7777 works. Testing the switchboard from a normal phones works. Testing the switchboard from a mobile phone fails. Looking at the log file I can't see anything. I used 'asterisk -rvvvv' and 'tail -f /var/log/asterisk/full' to see the live output and scan the logs. I guess I don't see anything because it's simply not recognising the DTMF tones. I did brief research and found an old setting for SIP phones, 'rfc2833compensate=yes', and tried adding this to 'sip_general_custom.conf'. After that I did 'core restart when convenient' but that didn't make any difference. Could anyone give me some additional troubleshooting steps?
