Today i am working on a batch operation registering several sensors on IBM Watson IoT.
Using curl you need to encode de API KEY and API TOKEN
It easy using the MAC terminal console
To encode just type on terminal: echo -n ‘user:password’ | base64
the result is —> dXNlcjpwYXNzd29yZA==
To decode just type: echo ‘dXNlcjpwYXNzd29yZA==’ | base64 -D
the result is —> user:password
I setup the connection to cloudant service to store historical data of my IoT devices. When i click “done” an pop up window appears asking to authorize the connection to Cloudant Service. I confirm to authorize and i get the message 502 Bad Gateway: Registered endpoint failed to handle the request. and i can’t store iot device data on cloudant. I tried several times.
I search a lot about this error message with no luck . To solve the problem erase all IBM cookies from you browser and restart it.
At a high-level, a hybrid cloud is a mixture of private and a public cloud environments that work in tandem to run your workloads and apps. That definition sounds straight-forward, but when you dive in and start to work, you can find hybrid cloud architectures difficult to manage without the right tools.
You can watch a video of a real-world example to clearly understand what works well on a public cloud environment and what is best in a private environment.
I found it today when googling for some solution for my mac and it works!
The web is moving to HTTPS, preventing network attackers from observing or injecting page contents. But HTTPS needs TLS certificates, and while deployment is increasingly a solved issue thanks to the ACME protocol and Let’s Encrypt, development still mostly ends up happening over HTTP because no one can get an universally valid certificate for localhost.
This is a problem because more and more browser features are being made available only to secure origins, and testing with HTTP hides any mixed content issues that can break a production HTTPS website. Developing with HTTPS should be as easy as deploying with HTTPS.

With the launch of Domino 10 knowledge of JavaScript and how to work with JSON Objects will be required for the new development model.
As i am working on a IoT project i need to learn JSONata to manipulate lots of JSON objects.
JSONata is underpinned by the semantics of the location path inspired by XPath, the ability to format the output into any JSON structure inspired by XQuery, and the functional programming model inspired by Scheme.
The semantics of the location path inspired by XPath
The ability to format the output into any JSON structure inspired by XQuery
The functional programming model inspired by Scheme.
The lightweight footprint of the runtime processor enables it to run in the web browser or as a node.js module with no package dependencies.

Today I gave a presentation about machine learning and IoT focusing on industrial maintenance. The event was the third industrial maintenance workshop in Belo Horizonte. An opportunity to talk about IBM Watson and IIoT to the industry in my region.
Domino 10 beta 2 started last week. I download the files and wish to run it on docker.
I follow Tim Clark’s blog series about Domino 9.0.1 on Docker.
I change a few lines on dockerfile (just change the installation file name).
Another difference was the line to start the container. I add the port 8585 to do a remote setup
docker run -it -p 1352:1352 -p 8888:80 -p 8443:443 -p 8585:8585 –name Domino10Beta -v domino_data:/local/notesdata kenio:Domino10Beta2
I ordered two servers from SoftLayer to host some wordpress sites.
I tried to update the server using yum update but i got the error bellow
Loading mirror speeds from cached hostfile
http://mirrors.service.networklayer.com/centos/7/os/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://mirrors.service.networklayer.com/centos/7/os/x86_64/repodata/repomd.xml: (28, ‘Connection timed out after 30001 milliseconds’)

The first problem: DNS server is not correct on resolv.conf
The second problem: The repos for yum was changed by softlayer and you need to revert the file CentOS-Base.repo to the original file.
