Has anyone done a comparison between R connect Server and Power BI. We are trying to work on the benefits of R Connect server over Power BI in order to convince our super strict IT management to go with R Connect Server.
Thank you.
You should figure out what decision variables are important to you. This RStudio thread goes into detail about the benefits, mostly if you are going lightweight it is better. Most likely your users are more technical and want more ability to build powerful tools themselves.
Power BI seems to be better for the Excel "power" users. It does not handle large datasets well, and most likely this is for a non-technical crowd.
Consider the end users before all else, then work backward from there.

I have included an R Script in a PowerQuery in Power BI to transform data. This works in Power BI Desktop, however when I push to Power BI Server I receive the following error message when looking at the (Enterprise) gateway:
Extension{"extensionDataSourceKind":"R","extensionDataSourcePath":"R"} Cannot be added to gateway
Doing some Googling / looking at the Power BI Community pages suggests that the Enterprise Gateway does not support R Scripts - something to do with it being too memory intensive for Microsoft to want to support running R on the cloud server. But I can find very little concrete documentation on this (more opinion):
https://www.sqlgene.com/2018/09/25/power-bi-error-r-cannot-be-added-to-gateway/
https://community.powerbi.com/t5/Power-Query/Refresh-R-Scripts-with-Personal-Gateway/m-p/445494#M17917
Has anyone found a solution to this or developed any suitable workarounds? e.g. can the Personal Gateway be used as an alternative or does the Enterprise Gateway support the running of Python Scripts?
I'm keen to hear of any strategies that people have found to running R scripts on the Power BI Service.
You cannot use the enterprise gateway for R Scripts in Power Query. You can use the personal gateway, it will work on that, that is the current work around.
One client I have transforms the data on SQL Server using R Services module, then loads the data from there, that is one possible work around.
I am currently working in computer networking area, more specifically working in developing real time application for ad hoc network.Recently I have worked in machine learning and I love it.I want to know is there any way I could work with both (Computer network and machine learning).I have tried a lot but did not find yet.
Machine learning is tricky, most people just think of it as using library functions. One needs to develop differentiation across ML algorithms (not only use cases). So make sure to join university course and some hands on at problem solving not program writing.
I'm interested in using a statistical programming language within a web site I'm building to do high performance stats processing that will then be displayed to the web.
I'm wondering if an R compiler can be embedded within a web server and threaded to work well with the LAMP stack so that it can work smoothly with the front-end and back-end of the web site and improve the performance of the site.
If R is not the right choice for such an application, then perhaps there is another tool that is?
The general rule is that webserver should do NO calculations -- whatever you do, it will always end in a bad user experience. The way is that the server should respond to calculation request by scheduling the job for some worker process, give the user some nice working status and then push the results obtained from worker when they are ready (most likely with AJAX polling or some more recent COMET idea).
Of course this requires some RPC protocol to R and some queuing agent -- this can be done either with background processes (easy yet slow), R HTTP servers (more difficult yet faster), or real RPC like Rserve or triggr (hard, yet fast to ultra-fast).
You are confusing two issues.
Yes, R can be used via a webplatform. In fact, the R FAQ has an entire section on this. In the fifteen+ years that both R and 'the Web' have ridden to prominence, many such frameworks have been proposed. And since R 2.13.0 R even has its own embedded web server (to drive documentation display).
Yes, R scripts can run faster via the bytecode compiler, but that does not give you orders of magnitude.
Voxeo provide a free IVR for development purposes, but I was wondering if there is a much simpler form of test IVR, perhaps which runs on the local machine and uses your microphone and speakers instead of the telephony network?
You should be able to do this with any VoiceXML IVR that supports SIP in combination with a softphone. There are a variety that do, including Voxeo. For a lower cost solution, you might be able to do something with Asterisk and the VXI* based browser that runs on the platform.
Note, be aware that VoiceXML browsers vary from platform to platform. This may or may not be an issue for you when developing and testing your application. You can write fairly portable applications with just a bit of experience across platforms, but if you are new to VoiceXML, knowing how just one platform has implemented the specification can get you into trouble.
As a different approach, you could look at Voiyager that also allows you to drive the call flow with text input or via a programming interface. Disclaimer: I am part of the development team and company that produces Voiyager.
I would like to develop a Network Inventory application that works on any operating system.
Reports on every possible resource attacehd to a network.
Reports all pertinent details of hardware and software.
Thats (and i hate to use the phrase) my "End Game".
However I am running before i can crawl here.
I have no experience of this type of development, e.g. discovering a computers hardware and software settings.
I've spent almost two weeks googling and come up short! :-(.
So I am turning to you to ask these questions:-
My first step is to find an existing open source project i can incorporate into my own code that extracts the fine grained details i am after, e.g. EVERYTHING there is to know about the hardaware and software on a single machine.
Does this project exist? or do i have to develop that first?
Have i got to write all this in C?
I am guessing getting this information about a computer is going to be easier than for printers, scanners, routers etc... e.g. everything else you would find attached to a network.
Once i have access to a single computers details i then need to investigate how i can traverse an entire newtork of printers, scanners, routers, load balancers, switches, firewalls, workstations, servers, storeage devices, laptops, monitors, the list goes on and on
One problem i have is i dont have a 1000 machine newtork to play on!
Is there any such resource available on theinternet? (is that a silly question?)
Anywho, if you dont ask you wont find out!
One aspect iam really looking forward to finding out how to travers the entire network,
should i be using TCP/IP for this?
Whats a good site, blog, usergorup, book for TCP/IP development?
How do i go about getting through firewalls?
How many questions can i ask in one go? :-)
My previous question on this topic ended up with PYTHON being championed as the language/script to go with to develop this application in.
Having looked at a few PYTHON examples they all seemed to be related to WINDOWS networks
and interrogating Windows Management Instrumentation (WMI). I had the feeling you cant rely on whats in WMI, and even if you can that s no good for UNIX netwrks.
Surely there exist common code for extracting hardware and software details from a computer? Why cant i find it on the internet?
Pease help?
Theres no prizes though :-(
Thanks in advance
I would like to appologise if i have broken forum rules or not tried hard enough on my own before asking for assistance.
I just would like to start moving forward with this as its one of the best projects i have been involved with.
I am inspired by the many differnt number of challenges involved and that if i manage to produce a useful application at the end of it it would hopefully be extremely helpful to many people.
That sit
Thanks in advance

as a software vendor of a discovery solution, I can just say: Respect, that you want to start a new one :-). Just in case you are interested in what it could look like: http://www.jdisc.com
Now to some of our experience:
Programming Language:
I wouldn't write it in C. Use Java or .NET. Those languages have great advantages when it comes to tracking down errors or problems. For instance, in Java (and I guess also in .NET), you can see the stack trace when something is failing. For some pieces of code (e.g. WMI access), you might need to use C++ or C (e.g. access to native APIs from Microsoft). Use a native interface or a COM bridge from Java. In .NET, it should even be easier to access the Windows APIs).
Devices:
well, network printers, router, and switches are actually easier to discover. They usually expose their information via SNMP. SNMP is pretty easy to use and pretty robust. Getting information from Windows (or even Unix) systems is a bit trickier. Protocols can be blocked, misconfigured, messed up... We had cases, where WMI was simply hanging when requesting data from a remote device.
Test Devices:
Since we are also a smaller company, we also do not have 1000 different devices to test with. But, there are some things that might help:
a) For SNMP devices use a SNMP simulator. We use MIMIC 9.0 from Gambit Solutions and we are pretty happy with it. You can import SNMP walks from network devices and simulate the device as if it would be in your network.
b) Secondly, use virtualization whenever possible. With VMware, you can install Windows, Linux, or even Solaris. We also use a project called GNS3 to emulate Cisco Routers, Firewalls or Juniper routers.
c)You can test the rest of the devices only, if you have a customer that helps you with testing and implementing new devices.
This are just some ideas to start with. But I have to tell you, that it is not trivial and it takes a lot of time....
Hope that you got some ideas to start with...
I don't know that it's open source, but we use Spiceworks (http://www.spiceworks.com) here as an IT management platform. You may get some use out of exploring that.
