CouchDB - Replication Test - between CouchDB servers on Android 2.2.1 and Windows 7

Manish Agrawal — Thu, 18 Nov 2010 03:10:32 GMT

Step 1:

Download CouchDB on your Android phone from Android Market Place:

info available at: http://www.couchone.com/android

Step 2:

Download CouchDB on your Windows machine

info available at: http://www.couchone.com/get#win

Download link: http://dl.couchone.com/dl/6d2f7222ef93871d5151d1462f002941/couchdb_1-1.00%20erlangR14A%20delayed-commits-false.zip

after unzip, it looks like this:

Step 3:

Check IP of your Windows machine

Note: Your Android phone and Windows machine shall be on the same network (in case of local network).

Step 4:

On your Windows machine, Goto etc/couchdb folder in the CouchDB directory and change the IP from 127.0.0.1 to your Windows machine IP in local.ini file

Step 5:

On your Windows machine, Goto bin/ folder in the CouchDB directory,

Run the couchdb.bat file, it will show the following log

Erlang R14A (erts-5.8) [source] [smp:2:2] [rq:2] [async-threads:0]

Eshell V5.8 (abort with ^G)

1> Apache CouchDB 1.0.0 (LogLevel=info) is starting.

Apache CouchDB has started. Time to relax.

[info] [<0.44.0>] Apache CouchDB has started on http://192.168.0.2:5984/

Step 6:

Access http://192.168.0.2:5984/_utils URL from your Android phone browser

It should show the CouchDB page with database names.

And immediately it will show this log in the Erlang server window:

[info] [<0.107.0>] 192.168.0.3 - - 'GET' /_utils 301

[info] [<0.107.0>] 192.168.0.3 - - 'GET' /_all_dbs 200

[info] [<0.169.0>] 192.168.0.3 - - 'GET' /_session 200

[info] [<0.107.0>] 192.168.0.3 - - 'GET' / 200

[info] [<0.169.0>] 192.168.0.3 - - 'GET' /_users/ 200

[info] [<0.168.0>] 192.168.0.3 - - 'GET' /xyz/ 200’

Step 7:

Now Open the CouchDB on Android phone Notification bar. (You will see the local IP of the phone i.e. 127.0.0.1:5984)

Create a new database… (in my case database name was xyzA)

Go to Replicator link on the right side of the page

In From DB, fill the http url of your CouchDB running on your Windows desktop

for e.g. http://192.168.0.2:5984/xyz (xyz was the database name on my Windows CouchDB)

In To DB, select the newly created database from the dropdown which shows _replicator as selected by default.

or in case if the newly created db is not there in the dropdown list,

fill the http URL, for e.g. http://127.0.0.1:5984/xyzA

Note: even though new database is created, it may not appear on the Local Database dropdown on the Replicator page

Remember to Reload/Refresh the page in your Android Browser always, you may have to do it at many different times on various pages.

You can select Continuous check box for continuous replication between the two.

Press Replicate button

Immediately it will show this log in the Erlang server window:

[info] [<0.742.0>] 192.168.0.3 - - 'GET' /xyz/ 200

[info] [<0.743.0>] 192.168.0.3 - - 'GET' /xyz/_local%2F34c99c134a502c2cd41d6df7775902e2 404

[info] [<0.744.0>] 192.168.0.3 - - 'GET' /xyz/_local%2F6ed566d89c8c3c6b5c00ddb810717b2d 404

[info] [<0.745.0>] 192.168.0.3 - - 'GET' /xyz/_changes?style=all_docs&heartbeat=10000&since=0&feed=continuous 200

[info] [<0.746.0>] 192.168.0.3 - - 'GET' /xyz/e63b8aa6b2685686199c7e131900052f?open_revs=["1-6371fc9e2fa97f39bd567a3649b3a825"]&revs=true&latest=true&att_encoding_info=true 200

[info] [<0.749.0>] 192.168.0.3 - - 'GET' /xyz/f1ca5a35948b802b82a346a792000e20?open_revs=["2-a73c0007b41ce0b84b6960cd55b2d487"]&revs=true&latest=true&att_encoding_info=true 200

[info] [<0.750.0>] 192.168.0.3 - - 'POST' /xyz/_ensure_full_commit?seq=3 201

[info] [<0.757.0>] 192.168.0.3 - - 'PUT' /xyz/_local%2F34c99c134a502c2cd41d6df7775902e2 201

Problems identified during this exercise:

1. In CouchDB web UI, to change any field value, one has to double click, but if you have opened CouchDB Web UI in Android Browser, double click/double tap work as zoom feature!!

2. Continuous Replication stopped working, once my Android phone moved from WiFi to EDGE and back, I had to restart CouchDB on Android and again set up the replication!!

Voice Message (VM)

Manish Agrawal — Fri, 13 Nov 2009 00:33:24 GMT

I have posted a Poll on Linked IN, to study about the pattern of usage of Voice Message and its awareness.

I request you, to kindly spare few seconds of yours to provide your valuable answer.

Poll Question is:

What do U do, when the Person U are calling is not reachable / not picking & a Voice Prompts u to leave a Voice Message (VM)?

You can answer the Poll on Linked IN site (recommended, as it will give very good comparitve analysis) by clicking on this link: http://polls.linkedin.com/p/65807/ugsqd

Or if that is not possible, then by leaving your answer (from below mentioned options) as comment to this post:

1. Leave a VM
2. Don't leave VM & wait for callback
3. Don't leave VM & later send a SMS
4. Don't leave VM & try calling again later
5. Don't know, What is Voice Message (VM)

Thanks in advance...

UUI - Ubiquitous User Interface

Manish Agrawal — Tue, 28 Jul 2009 22:32:30 GMT

Finally, The world is evolving towards a new mode of interaction.

Where human doesn't haveto give inputs to machines using some input devices like keyboard, mouse, touch etc. rather machines are made capable to understand human body movements and take inputs accordingly.

I will like to give it a new name UUI - i.e. Ubiquitous User Interface

Some examples of this are Accelerometer based inputs in many devices, Microsoft's new Project Natal for XBOX 360 .

Refer my previous blog posts on Sixth Sense, iPhone SDK showing accelerometer based input. And now have a look at this demo of Microsoft's Project Natal for XBOX 360:

It shows, how technology is gradually evolving

from Punch Card based instructions to Command line based instructions to Mouse / Digital Pen / Joystick to Voice / Touch / Accelerometer and now to Observation

for interfaces, from Console to GUI to IVR to UUI

What's Next ?? TUI -- Thought User Interface User can just think of an action and machine will understand :)

Sixth Sense -- What a Demo!!

Manish Agrawal — Mon, 16 Mar 2009 13:20:22 GMT

When you think out of the box, this is what is the possibility, you can make something so advanced with something so simple... and that also cheaper than the current available options....

Thanks to Parnav Mistry and Pattie Maes for such a brilliant work they have done.

I bet you will not be able to stop yourself from clapping after looking at the video / future.

Convert PDF to Word for Free

Manish Agrawal — Tue, 30 Dec 2008 01:33:42 GMT

Got a good link to convert PDF to Word and that too free.

I checked converting one PDF with Image and Page Header / Footer Margins. And bang it goes... it has converted it very nicely.

Only trade-off was the size of the document, it converted 386kb PDF file to 1.42 mb MS Word file. But never mind, as the quality of output was very good.
