I am new to Apache Arrow and want to run some tests re IPC setup (java or python).
Any other Arrow resources I should be looking at?
There is a pull request under review demonstrating the basics of java.
Similar python documentation is available on the Apache Arrow Website

I'm trying to figure out a good way for my company to have a local repository/package manager (something a little more user friendly than git). I like Teacup and we are using ActiveState Tcl anyways (Tcl 8.5, we have legacy systems using this version).
Can I use Teacup to make my own offline package manager repo? Sort of like how you can do that with Anaconda in Python. It has to be totally offline but I want to be able to upload packages to it when I make them and let Teacup handle the installation of them for other users in my company.
I've read through this page a little bit but it is missing some content.
You are looking for the server-side component to the "teaparty": teapot as the server providing for the teacup client:
https://wiki.tcl-lang.org/page/Teapot
While there is a dedicated teapot (server) implementation available from ActiveState, the client/ server protocol is straight forward: It is about generating markup (HTML) resources delivered via HTTP (containing table DOM structures) and processed by the teacup client. As always, these resources can be generated statically or dynamically, or anything inbetween.
Watch the examples at:
http://teapot.rkeene.org/index.html
Better:
view-source:http://teapot.rkeene.org/index.html
Assuming your Tcl projects are hosted using some SCM repo, you may provide some repository (CD, pipeline) action to produce a static resource structure served by a HTTP server of your choice? The original teacup client can be used against this resource collection.
I am new to Istio service mesh. I have to integrate/configure appdynamics in istio. I have no clue how to do that. Anything related to this would help. Any example or related links or video...anything.
From checking out the code for Istio - https://github.com/istio - this appears to be an application with components written in Go and C++ which are deployed to containers using Kubernetes.
This would mean that for monitoring you should be looking at:
Go SDK - https://docs.appdynamics.com/display/PRO21/Go+SDK - To instrument Go elements
C/C++ SDK - https://docs.appdynamics.com/display/PRO21/CCPP+SDK - To instrument C++ elements
Cluster Agent - https://docs.appdynamics.com/display/PRO21/Monitor+Kubernetes+with+the+Cluster+Agent - to monitor the containers
You have you work cut out for you here - both SDK's would require changes to the code being ran to get visibility.
Really new to graphhopper and an inexperienced java programmer so I need a little help extending graphhopper core. What I've done so far is install the graphhopper core from the link on the quickstart guide found here. I'm then able to follow the rest of the instructions and get a local instance up and running just fine and interact with it using R and the API instructions. I would like to add support for bike, foot, and transit routing. As per the answer found here, I first attempted to modify graph.flagEncoders=car to graph.flagEncoders=car,foot, bike in the "config-example.properties" file. And that's where things fail. When attempting to run the program in the command prompt, it then fails at this point. Any help and direction would be greatly appreciated.
Edit: 8/24/2018
Below is a screenshot of the command prompt when using graph.flagEncoders=car,foot, bike in the "config-example.properties" file. Note that I'm using the example osm data found on the quickstart guide.
As per Karussell's comment, in this instance all you have to do is delete the *.osm-gh cache folder that's created by Graphhopper.
I've recently purchased a Mac Mini with the only purpose of being a server.
I'm a C programmer, learning Lua and Obj-C at the moment. I'm trying to set up a website, a kind of CV/Personal Promotion site.
I've been looking at MAMP for a while however, I would like to use nginx and Lua in place of Apache and PHP.
My thought is using Lua instead of PHP would help accelerate my learning curve.
Does anyone have experience with this setup or using lua as server scripting?
Cheers
There is Jan Kneschke's lua magnet of which I maintain a fork on github. I use this in conjunction with FastCGI (and luasql.sqlite3) for a small message board, which was previously written in PHP, then python.
The PHP and python versions each performed so-so (which may be due to me not being a good PHP/Python programmer at that time), and each took about 10-40MB of RAM. The Lua version runs within 1MB and is measurably faster. Also the code is easier to read, IMHO.
Note that you will need some helper modules to work with POST requests. The download files to the book Lighttpd contain a version of cgi.lua that does the trick. If there is interest, I can make it available on my GitHub.
I am looking to build an educational web service where the end user can type up the code in some language (say Java or python) for a given problem and the service should be able to tell if the code compiles and show output of the code for a few test cases. I am trying to get an idea from the community about a) if something like this exists b) how to build it.
Obviously this service will support a very limited subset of the language for security reasons. It would be cool to be able to do majority of this on the client side, but I'd be happy with doing this on the server side as well.
Are there any such frameworks that I can use for creating a sandbox environment?
Is there any particular language for which it would be particularly easier?
