Sun Tech Days 2008 - Day 1 Disappoints!

This was 10th anniversary of Sun Tech Days and expectations were running understandably very high. Having attended the event last year, I was expecting higher standards both in content as well as event organization.

HICC's 5000 capacity hall is huge and I still remember the last year's keynote which had entire hall packed and still people were standing. But this year the keynote took place in only Hall 3 and 4 combined (entire hall is composed of 4 halls), which is nearly 60% of the entire hall. Was the attendance this low this year?

Address by Sun India CTO Divyeshwar Shah was ok, but it was Rich Green, EVP Sun Microsystems, whom everyone was waiting for. And was the person on stage really Rich Green I have heard about? This person seemed to be some marketing guy from Sun Microsystems who showed marketing slides about almost ALL Sun products! What a yawn!

Technology demos were tiresome, stale and unimpressive! Snow and rain effects on Solaris desktop and creating an application using jMaki are Sun's ideas of 'Tomorrow's Technologies'? Compared to the technology showcase last year which launched JavaFX with a bang, this was stale as a fungus infected bread!

Most of the other technical sessions are mediocre at best. The sessions on AJAX, jMAKI and RIA were 'oh so yesterday' and the one of JRuby was over before you can spell 'Ruby On Rails' (ok, it lasted more than that!). But I have heard that NetBeans Profiling and JavaFX were pretty good.

I am going tomorrow as well. Let's hope things turn out better!

How to upload to Google Cloud Storage buckets using CURL

Signed URLs are pretty nifty feature given by Google Cloud Platform to let anyone access your cloud storage (bucket or any file in the bucket) without need to sign in. Official documentation gives step by step details as to how to read/write to the bucket using gsutil or through a program. This article will tell you how to upload a file to the bucket using curl so that any client which doesn't have cloud SDK installed can do this using a simple script. This command creates a signed PUT URL for your bucket. gsutil signurl -c 'text/plain' -m PUT serviceAccount.json gs://test_bucket_location Here is my URL: https://storage.googleapis.com/test_sl?GoogleAccessId=my-project-id@appspot.gserviceaccount.com&Expires=1490266627&Signature=UfKBNHWtjLKSBEcUQUKDeQtSQV6YCleE9hGG%2BCxVEjDOmkDxwkC%2BPtEg63pjDBHyKhVOnhspP1%2FAVSr%2B%2Fty8Ps7MSQ0lM2YHkbPeqjTiUcAfsbdcuXUMbe3p8FysRUFMe2dSikehBJWtbYtjb%2BNCw3L09c7fLFyAoJafIcnoIz7iJGP%2Br6gAUkSnZXgbVjr6wjN%2FIaudXIqA...

Running Apache Beam pipeline using Spark Runner on a local standalone Spark Cluster

The best thing about Apache Beam ( B atch + Str eam ) is that multiple runners can be plugged in and same pipeline can be run using Spark, Flink or Google Cloud Dataflow. If you are a beginner like me and want to run a simple pipeline using Spark Runner then whole setup may be tad daunting. Start with Beam's WordCount examples which help you quickstart with running pipelines using different types of runners. There are code snippets for running the same pipeline using different types of runners but here the code is running on your local system using Spark libraries which is good for testing and debugging pipeline. If you want to run the pipeline on a Spark cluster you need to do a little more work! Let's start by setting up a simple standalone single-node cluster on our local machine. Extending the cluster is as easy as running a command on another machine, which you want to add to cluster. Start with the obvious: install spark on your machine! (Remember to have Java a...

Example of Using SimpleHttpOperator to make POST call

Airflow has SimpleHttpOperator which can be used to invoke REST APIs. However using this operator is not exactly straightforward. Airflow needs to be told about the connection parameters and all the other information that is needed to connect to external system. For this we need to create Connections. Open 'Connections' page through Admin->Connections link. Expand the dropdown to see the various types of connection options available. For a REST call, create an HTTP connection. Give the host URL and any other details if required. Now when we write our task using SimpleHttpOperator we will need to refer to the connection that was just created. The task below is making a post call to https://reqres.in/api/users API and passing it some data in JSON format. myHttpTask = SimpleHttpOperator( task_id='get_op', method='POST', http_conn_id='dcro', data=json.dumps({ "name":"Morpheus", " job ":" L...
