H2O Steam deploy can't connect to Prediction Service Builder - h2o

I am trying to use h2o steam (running on localhost) to deploy a model. After importing the model from h2o flow, clicking the "deploy model" option in the "models" section of the project, filling out the resulting dialog box, and clicking the "deploy" button, the following messages are displayed:
At first I thought that it was because maybe I needed to start up the service builder on my own, so I started it up following the docs here, but still got the same error. Any suggestions would be appreciated. Thanks :)

Just make sure jetty HTTP server is running locally by executing the following in your shell:
java -jar var/master/assets/jetty-runner.jar var/master/assets/ROOT.war

Looking here, it seems like I would need to "override" some kind of default browser restriction for accessing localhost:8080 (which is what I assume steam is trying to do to launch the service builder (I don't know much about networking related stuff)). I got around this by launching steam with the command:
$ ./steam serve master --prediction-service-host=localhost --prediction-service-port-range=12345:22345
where the ports are some arbitrary range between (1025, 65535) which I got by word-searching the a page of the steam source code (line 182 as of the date of this posting).
Doing this lets me deploy the models through the steam dialog without any error messages. Again, I don't know much about networking related stuff, so if anyone has a better way to solve this problem (ie. allow access of localhost:8080) please post or comment. Thanks.

Internal Server Error- http://localhost:1080/webTours/home.html

Application: http://localhost:1080/webTours/home.html [I intend to use it for Jmeter testing]
Below error is displayed when I am trying to click on "sign up now" link. Kindly help to fix it. Pls note, I have strawberry-perl-5.30.0.1-64bit.msi also installed and path is set to the environment.
Internal Server Error The server encountered an internal error or
misconfiguration and was unable to complete your request.
Please contact the server administrator, admin#localhost and inform
them of the time the error occurred, and anything you might have done
that may have caused the error.
More information about this error may be available in the server error
log.
Thanks.
Probably, you need to do the correlation for the dynamic parameters like sessionID etc.
Record two scripts using tools like fiddler or LR or any other sniffing tool and compare two scripts to find out dynamic variables required. Then correlate them. For correlation, identify the first occurrence of the variable in the response then extract them using post processor and pass them further below/to all the request that requires it.
Hope this helps.
It appears that your Web Tours Sample Application installation is broken, looking into MICRO FOCUS SUPPORTED stanza in the application details you should contact Micro Focus Support or ask the question in Micro Focus Community Forums.
In the meantime you can use http://blazedemo.com/ page and Getting Started with JMeter - A Basic Tutorial as the alternative test application for your JMeter training
If you are not getting internal server error while sign up (or) accessing administration link then follow the below,
a. close the server from the cmd
b. In the Web Tours 1.0 parent folder, find the file .msi file: strawberry-perl-5.10.1.0
c. Double click on strawberry-perl-5.10.1.0 msi file to install
d. Once it is installed, Now re-start the server (Double click on StartServer.bat file) under WebTours sub-folder
e. Now, Go to link http://localhost:1080/webtours/home.html

Unable to Create Common Data Service DB in Default Environment Power Apps

I am unable to create a new Common Data Service Database in my Power Apps default environment. Please see the error text below.
It looks like you don't have permission to use the Common Data Service
in this environment. Switch to a different environment, or create your
own.
Which as I understand I should be able to create after the Microsoft Business Application October 2018 update as listed in the article available at following link.
https://community.dynamics.com/365/b/dynamicscitizendeveloper/archive/2018/10/17/demystifying-dynamics-365-and-powerapps-environments-part-1
Also when I try to create a Common Data Service app in my default environment, I encounter following error.
The data did not load correctly. Please try again.
The environment 'Default-57e1485d-1197-4afd-b792-5c423ab508d9' is not
linked to a new CDS 2.0 instance. The operation 'ListInstanceMetadata'
is forbidden for unlinked environments
Moreover I am unable to see the default environment on https://admin.powerapps.com/environments, I can only see the Sandbox environment there.
Any ideas what I am missing here?
Thank you.
Someone else faced a similar issue and I read in one of the threads about deleting the browser cache and trying it again or trying it in a different browser resolved the issue. Could you try these first level steps and check if you still have these issues?
Ref: https://powerusers.microsoft.com/t5/Common-Data-Service-for-Apps/Default-Environment-Error-on-CDS/m-p/233582#M1281
Also, for your permission error ref: https://powerusers.microsoft.com/t5/Common-Data-Service-for-Apps/Common-Data-Service-Business-Flows/td-p/142053
I have not validated these findings. But as these answers are from MS and PowerApps team, hope it helps!

Unable to use activator on my Mac - get a timeout exception when I try and make an app from template

So I'm following this tutorial:
https://www.playframework.com/documentation/2.3.x/Installing
It all seems installed - i.e. all the commands work but when I try and call:
activator new my-first-app play-scala
I get the following:
Fetching the latest list of templates...
Could not fetch the updated list of templates. Using the local cache.
Check your proxy settings or increase the timeout. For more details see:
http://typesafe.com/activator/docs
OK, application "another-app" is being created using the "play-scala" template.
akka.pattern.AskTimeoutException: Ask timed out on [Actor[akka://default/user/template-cache#1575831997]] after [10000 ms]

at java.lang.Thread.run(Thread.java:744)
And nothing happens.
I just installed it on a PC in my house under the same network so I don't think my connection is the issue. I'm not using a proxy either..
Got any ideas? I've been trying to get this working for over a day now.
I'm on OSX Yosemite by the way.
I sometimes have timeouts too, especially while working in the university on some sloppy WLAN.
There are two types of activator, the usual light-weight one and the offline version. In the second, all repositories are present so the activator does not need to gather anything from the internet.
When you go to https://www.playframework.com/download ... look for the offline distribution (around 400MB) and install it like the normal activator.
If this solves your problem, there was something wrong with the activator trying to get something from a repository (you said that you can run the project but get server timeouts).
[EDIT]: You can also set the timeout to 30 seconds and see if this helps
activator -Dactivator.timeout=30s new "project name"

CodeIgniter error - unable to connect to database using the provided settings

I have a CodeIgniter setup that has been running fine for the past 2 months and recently I keep getting:
CodeIgniter error- unable to connect to database using the provided settings
I've recently added a new domain that has a landing page for the database login (zPanel), but I don't see how that could have caused a problem--maybe the page keeps getting directory attacked or something, but I'm not sure.
Is there a way to check if this is the problem through logs? I'm at dead ends with this problem, as when I restart the server (DigitalOcean) it works fine again.
Really not sure. If anyone else has had a similar problem, I'd love to hear your solution.
Thanks.
I think your mysql is going down so Codeigniter can't connect to your database settings.
Please login to SSH and check processes by "TOP" comment. See what is using resources ram or cpu.
And check your mysql conf settings, be sure that everything written if its empty it will cause alot of problems.

Docpad Livereload plugin + Cloud9 IDE

Has anyone successfully got this combination working?
It seems to run correctly on the client side, but there's something about Cloud9's file system that means changes aren't detected when files are saved, so I'm having to restart the app every time.
problem is that cloud 9 gives u only one port(process.env.PORT) and you are using this port for running web server and you don't any have additional port for live-reload server.
for CSS you can use Live.js
Safareli is correct that Cloud 9 gives you only one port, but Live.js, the website Safareli linked in fact does work with refreshing everything, although I don't know how taxing it is to C9 since it is refreshing for headers pretty much all the time.
