Couchbase Multi-Get over HTTP? Is it possible. Unable to install SDK - couchbase

Can Multi-Gets in Couchbase by performed via an HTTP Request? If so what is the Request/URL pattern? For installation restriction reasons I am unable to install the SDK

This will probably help you, http://www.couchbase.com/communities/cn/q-and-a/rest-api-getting-data
What installation restrictions mean you can't use the SDK? I would recommend the SDK over circumventing the standard couchbase interaction methods.

How we can monitor a service status using Zabbix?

We are using Zabbix for server monitoring and its working fine for system resources like disk, CPU, memory etc.
Now we want to monitor some services also whether they are running fine or not like Apache, Nginx, Puma, Sidekiq etc.
Can you please help me how we can monitor such services using Zabbix?
Any guidance will be appreciated.
Thanks in advance.
You should refer to the documentation, it covers windows service monitoring and generic process monitoring with proc.* items.
Here you can find the supported item by platform matrix.
There's an external template for systemd lld, you can find it on Zabbix Share
for Nginx monitoring you can use that template
also take a look this repository, probably you can find there something useful
For sidekiq specifically, using
proc.num[,,,sidekiq]
seems to work. It uses the cmdline -argument.

Does ejabberd community edition support rest API

I can't find clear information about the differences between Ejabberd Business and Ejabberd community (apart from the list of RFC/XEP here : https://www.process-one.net/en/ejabberd/protocols/).
Especially about the rest API : does community edition support it ?
In the documentation (https://docs.ejabberd.im/developer/ejabberd-api/) there is no info about which functionnality is supported by which version.
I also found this page : https://feedback.process-one.net/support/solutions/folders/6000076557 on the Business edition features but it seems to be outdated.
Thank you for your help.
Regards
If you enable mod_http_api, it provides ReST API in JSON format. Alternatively, if you install mod_rest from ejabberd-contrib git repository, you can execute commands with HTTP POST queries.

How to use GRUB2 with UEFI for secure booting Ubuntu?

I have a mirco computer board such as BeagleBone black.How I can make secure boot of Ubuntu in it using Grub2 and UEFI?
You cannot use GRUB/UEFI with BBB.
You have to use U-Boot since that's the only officially (and actually) supported boot loader.
Please refer the user guide.
However, if you explain what kind of security you need, people here may suggest different solutions.

Does Graphhopper embedded code start a web server on local host?

At present I have a graphhopper instances running on server and use API from java application. I was thinking on migrating to embedded version as described here https://github.com/graphhopper/graphhopper/blob/0.4/docs/core/quickstart-from-source.md for various reasons.
It is not clear to me yet if I go this way would it actually start a graphhopper server on localhost? I have used some other products by embedding in java app and many of these products don't start server to speed up the app.
Anyone has tried this?
You can use GraphHopper as a library or as a web service that is started on localhost.
Please do not use version 0.4 it is very old. Use the most recent - 0.10 - instead.

JRuby SAML Authentication

I'm trying to set up a JRuby application to use SAML 2.0 Authentication against a simpleSAMLphp IdP. The intention is to eventually authenticate against Microsoft ADFS, but that solution is still being built.
I've tried a couple of different SAML solutions so far (ruby-saml, samlr), and they all seem to fail under JRuby (but work fine under MRI). I'm specifically using JRuby to utilise the JMS API and JDBC Connectors, so I can't really go back to MRI.
Does anyone know of a SAML implementation that works properly under JRuby? I'm quite happy to go down the path of using native Java classes if that's required, but it'd really help to have a starting point that I can build upon.
Thanks in advance!
Is this application customer facing? If so, check out PingOne Application Provider Services. It's a hosted SAML SP from Ping Identity. You connect via a REST APS from your application and the service handles aol the complex SAML. Very simple to setup. The first connection is free as a bonus. [Note: I work for Ping]
