authorization - Cloud Foundry API access credentials for Custom Service

I'm developing a custom cloud foundry service for IBM Bluemix. When the service is provisioned by a user, I need my service to call the Cloud Foundry API and retrieve some information about the org for which the service is being provisioned. I see that I can do that by calling an API endpoint such as this one. Where do I get the Authorization token that my service will use to access the CF API? I don't want to use the token for my user account, which is all I seem to have access to....Read more

service - Upstart server killed using -9 or -15 but child processes are still alive

Upstart service is responsible for creating a gearman workers which run in parallel as number of cpus with the help of gnu-parallel. To understand the problem you can read my stackoverflow post which describes how to run workers in parallel. Fork processes indefinetly using gnu-parallel which catch individual exit errors and respawnUpstart service: workon.conf# workondescription "worker load"start on runlevel [2345]stop on runlevel [!2345]respawnscript exec seq 1000000 | parallel -N0 --joblog out.log ./workerend scriptOright. so above service...Read more

service - Fork processes indefinetly using gnu-parallel which catch individual exit errors and respawn

I guess the title gives you this thought. Another duplicate questionWell, let me explain this in detail.Okay, here we go.I am using gearman to handle stack of tasks. I have a gearman client which send this task to workers. To run these task concurrently, there must be more workers to handle a task at a time. Presently, I create workers as per number of cpus. In my case, its 4. So, 4 processes../worker & ./worker & ./worker & ./worker.I have same file running concurrently. But, I don't have their respective PIDs & their exit co...Read more

service - systemd can not import environment variables like $SSH_AUTH_SOCK

I wrote a service file in user space of systemd for starting up emacs daemon. This works quite well. But on startup of emacsclient I let decrypt my diary file. For that I have running gpg-agent. Normally when emacs is started pineentry-gtk pops up and prompts me for my private key password. But started the daemon with systemd the environment variables $SSH_AUTH_SOCKET, $GPG_AGENT_INFO and SSH_AGENT_PID are not known. Therefore no pineentry-gtk pops up. Several approaches to feed systemd from the system arround got stucked. I want to use a dynam...Read more

service - Where does DTOS as InputModel / ViewModel Fit in Layered Archicture

I'm trying to understand where does InputModel and ViewModels fit at the 4 Layer Architecture.Presentation | Application | Domain | InfrastructureGiven that the Application Layer takes care about exchange data beteween Presentation Layer and Domain Layer, I supposed that, they must live inside this layer, as well the adapter to convert It back to Domain Entity and vice versa.InputModels, also know as Commands, in ASP.NET MVC they can coincide with ViewModels.Makes no sense to me ViewModels inside the Presentation. From the Application Layer I s...Read more

OSGi Declarative services filter references at runtime

I've been trying some examples with OSGi Declarative Services (among other things, such as Blueprint) on Karaf. The problem I am trying to solve now, is how to get references to certain services at runtime (so annotations and/or XML are not really an option here)I will explain my use case:I am trying to design (so far only in my head, that's why I am still only experimenting with OSGi :) ) a system to control certain automation processes in industry. To communicate with devices, a special set of protocols is being used. To make the components a...Read more
