I have looked everywhere but cannot seem to figure out how to setup cloud coding on the Parse Open Server using Heroku.
I see this link which tells me what to put in the Index.js and Main.js file: Implementing Cloud Code on Open Source Parse Server. However, I cannot seem to find those files. Nor can I find the "cloud" folder.
How do I find the cloud folder?
I created the Parse Server on MongoDB using the "Deploy to Heroku" link on this page: https://github.com/ParsePlatform/parse-server-example. After creating my application by filling out all the information, I ran the command heroku git:clone -a yourAppName to clone the application files. However, when I use the command I obtain a empty repository and get the following message in my terminal:
Cloning into 'hyv3-moja'...
warning: You appear to have cloned an empty repository.
So, how/where do I find the cloud folder with main.js? Did I miss any step in creating the Parse Server?
I also tried using the Parse Command Line. However, when I try to use the parse new command, it requires me to login to a Parse account. However, since Parse is going down, they are not accepting new accounts and I did not have an account before. Regardless, this seems like a deadend.
So can someone please explain to me how to set up Cloud Code?? I want to create a code that decrements a column in the database every second so it operates like a timer. Basically, I want my application to create objects on the database that last a certain amount of time chosen by the user. For this example, ill say 24 hours. So from the moment it is created, I want to decrement those 24 hours in the database. That way when a user of my application clicks to view the object, I translate the time remaining from the database and just output that value to the user to show how much time is remaining for the life of the object.

I've spent 3 days beating my head against this before coming here in desperation.
So long story short I thought I'd fire up a simple PHP site to allow moderators of a gaming group I'm in the ability to start GCP servers on demand. I'm no developer so I'm looking at this from a Systems perspective to find the simplest solution to do the job.
I fired up an Ubuntu 18.04 machine on GCP and set it up with the Google SDK, authorised it for access to the project and was able to simply run gcloud commands which worked fine. Had some issues with the PHP file calling the shell script to run the same commands but with some testing I can see it's now calling the shell script no worries (it broadcasts wall "test") to console everytime I click the button on the PHP page.
However what does not happen is the execution of the gcloud command. If I manually run this shell script it starts up the instance no worries and broadcasts wall, if I click the button it broadcasts but that's it. I've set the files to have execution rights and I've even added the user nginx runs as to have sudo rights, putting sudo sh in front of the command in the PHP file also made no difference. Please find the bash script below:
#!/bin/bash
/usr/lib/google-cloud-sdk/bin/gcloud compute instances start arma3s1-prod --zone=australia-southeast1-b
wall "test"
Any help would be greatly appreciated, this coupled with an automated shut down would allow our gaming group to save money by only running the servers people want to play on.
Any more detail you want about the underlying system please let me know.
So I asked a PHP dev at work about this and in two seconds flat she pointed out the issue and now I feel stupid. In /etc/passwd the www-data user had /usr/sbin/nologin and after I fixed that running the script gcloud wanted permissions to write a log file to /var/www. Fixed those and it works fine. I'm not terribly worried about the page or even server being hacked and destroyed, I can recreate them pretty easily.
Thanks for the help though! Sometimes I think I just need to take a step back and get a set fresh of eyes on the problem.
When you launch a command while logged in, you have your account access rights to the Google cloud API but the PHP account doesn't have those.
Even if you add the www-data user to root, that won't fix the problem, maybe create some security issues but nothing more.
If you really want to do this you should create a service account and giving the json to the env variable, GOOGLE_APPLICATION_CREDENTIALS, which only have the rights on the compute instance inside your project this way your PHP should have enough rights to do what you are asking him.
Note that the issue with this method is that if you are hacked there is a change the instance hosting your PHP could be deleted too.
You could also try to make a call to prepared cloud function which will create the instance, this way, even if your instance is deleted the cloud function would still be there.
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.
This is a continuation of
https://community.h2o.ai/questions/2165/error-logging-in.html
and
https://community.h2o.ai/questions/1665/can-not-login-to-steam-osx.html
from my original post on community.h2o:
"""
Hi there, I am currently trying to set up an an API on my local machine using steam.
The documentation is out of date on http://docs.h2o.ai/steam/latest-stable/steam-docs/Installation.html#steam-start-flags which says to start the steam service for the first time, execute ./steam serve master --admin-name=admin --admin-password=admin the first time around to set the password. The current command is ./steam serve master --superuser-name=admin --superuser-password=admin but when I try to log in to 0.0.0.0:9000 (which is what it asks me to point the browser to) I get 2017/06/14 13:03:48 User admin does not exist I tried using single, double and no quotes.
Thank you for your time!
"""
The default username/password is superuser/superuser. The flags are not honored by steam server command and looks like its a bug. See config.toml file in the folder.
This breaks the very first developer experience with h2o/steam and is not encouraging.
./steam serve master --superuser-name=superuser --superuser-password=superuser works fine
Good Day.
I've been developing with meteorJS which uses mongodb. No problems there. I've been using the mongo shell to access the database on my dev machine (osx 10.11). This is my first project with mongo and when the shell would load, it would connect to db.test and I'd always show dbs and get the list of database, then use myApp.
Yesterday whenever I go into the shell and I type show dbs the only one shown is local 0.078GB. However my app is still working and pulling and pushing data to the database.
I've checked the dbpath in the mongod.conf and that seems ok. I'm not entirely sure about the exact order of things, but two things where different (I'm not sure if these happened prior to the show dbs not showing everything or after, and I'm not sure which came first):
when loading the mongo shell I was getting this error:
WARNING: soft rlimits too low. Number of files is 256, should be at least 1000"
I followed these directions which seemed to stop that error from appearing (https://github.com/basho/basho_docs/issues/1402 )
I use Meteor Toys and for the first time I update user.profile.companyName (which is a custom field within the standard profile from within the Meteor Toys widget.
Just odd that the app can still access the database and collections, but that the mongo shell doesn't show. I've update mongod via brew upgrade mongodb from 3.0.2 to 3.0.7 to no avail.
Any ideas?
If you want to use the regular mongo console you have to specify the port to be 3001 for meteor apps instead of the default 27017. Otherwise it's much simpler to just type meteor mongo and connect that way. Then you can type 'show collections' and it will show them all just like normal.
MongoDB do not show the database unless if there is minimum of one collection with a document in it.

I built an Analysis that displayed Results, error free. All is well.
Then, I added some filters to existing criteria sets. I also copied an existing criteria set, pasted it, and modified it's filters. When I try to display results, I see a View Display Error.
I’d like to revert back to that earlier functional version of the analyses, hopefully without manually undoing the all of filter & criteria changes I made since then.
If you’ve seen a feature like this, I’d like to hear about it!

Great question. There are many times in the past when we wished we had some simple SCM on the Oracle BI Web Catalog. There is currently no "out of the box" source control for the web catalog, but some simple work-arounds do exist.
If you have access server side where the web catalog lives you can start with the following approach.
Oracle BI Web Catalog Version Control Using GIT Server Side with CRON Job:
Make a backup of your web catalog!
Create a GIT Repository in the web cat
base directory where the root dir and root.atr file exist.
Initial commit eveything. ( git add -A; git commit -a -m
"initial commit"; git push )
Setup a CRON job to run a script Hourly,
Minutely, etc that will tell GIT to auto commit any
adds/deletes/modifications to your GIT repository. ( git add -A; git
commit -a -m "auto_commit_$(date +"%Y-%m-%d_%T")"; git push )
Here are the issues with this approach:
If the CRON runs hourly, and an Analysis changes 3 times in the hour
you'll be missing some versions in there.
No actual user submitted commit messages.
Object details such as the Objects pretty "Name" (caption), Description (user populated on Save Dialog), ACLs, and object custom properties are stored in a binary file format. These files have the .atr extension. The good news though is that the actual object definition is stored in a plain text file in XML (Without the .atr).
Take this as a baseline, and build upon it. Here is how you could step it up!
Use incron or other inotify based file monitoring such as ruby
based guard. Using this approach you could commit nearly
instantly anytime a user saves an object and the BI server updates
the file system.
Along with inotify, you could leverage the BI Soap API to retrieve the actual object details such as Description. This would allow you to create meaningfull commit messages. Or, parse the binary .atr file and pull the info out. Here are some good links to learn more about Web Cat ATR files: Link (Keep in mind this links are discussing OBI 10g. The binary format for 11G has changed slightly.)
