Subject: [Chennaipy] need help on making english-tamil transliteration using
 quillpad
Message-ID: <CAND2794N19YsaMKvjoJ8ZUc4JLpTjcY2cGg0W3x4hWvKuB5qLg@mail.gmail.com>

We are working on a telegram bot to translate all the strings on
openstreetmap.org to tamil

for that we get strings from osm, use google translator to get tamil
transliterations, use telegram bot to show the translations to users.
user can verify a tamil translation or give new translation.

code - https://github.com/Dineshkarthik/OSM-Translate-TelegramBot

demo video on bot - https://www.youtube.com/watch?v=dJkeRKuu1F8

Now, we think to remove google translation.

http://www.quillpad.in/index.html gives better tamil transliteration
than google.

it is based on python.
code - https://github.com/CognirelTech/Quillpad-Server

Need help on explore it and convert or guide us on how to use it as a
module or function in python so that we can get tamil transliteration
for a given english noun.

Can anyone help on this?

Reply here if you are interested.

Thanks.

Hi everyone,

This November 17th and 18th, "State Of The Map - Asia" is scheduled to
happen at Bangalore, Karnataka. This event is all about bringing together
the mappers as well as users of OpenStreetMap to discuss and learn from
each other about our works around OSM.

Some of us are actively contributing and improving OSM in our region
(Pondicherry, Villupuram & Chennai). I think this will be a good
opportunity to show and inspire others of what we have been doing and also
get inspired by the work of others too.

I will be participating in this event, If anyone else would like to join,
do reply here. Let's plan.

Also here is the website: http://stateofthemap.asia

They are also providing Scholarship (i.e helping us financially) if we
cannot afford to travel to Bangalore.

the audio file

Hi,

I built Quillpad-Server and run it on my local machine. It provides Json
based
web api for transliteration

When I tried to translate sholinganallur
http://localhost:8090/processWordJSON?inString=sholinganallur&lang=tamil

Response text
{"twords": [{"optmap": {"???????????????": ["?", "", "?", "?", "?", "??",
"?", "?", "?", "", "??", "?", "?", "??"], "???????????????": ["?", "", "?",
"?", "?", "??", "?", "?", "?", "", "??", "?", "?", "??"]}, "word": true,
"options": ["???????????????", "???????????????", "?????????"]}], "itrans":
"??????????????", "inString": "sholinganallur"}

Json value for the key itrans is most matching transliteration.
And options providing other matching transliterations.
So we could easily parse the response using python requests.

Regards,
Aravindhan K

Subject: [Chennaipy] Mutli- threading in cython
Message-ID: <CACWTKSr0p6Mf5PkxnOiZhUhmLySb0ff0iO4R4PZB8SpPrQs_BQ@mail.gmail.com>

Dear all,
I was programming for Andor CCD using SDK libraries in python using cython.
I have a piece of code within my .pyx script which does the function of
storing the data into a 3D array. While acquiring n frames, each of them is
stored in a 3D array named data, which later I would be displaying. But
this creates a bottleneck in my code.
Hence I need to introduce threading, such that for each frame to be stored
there are individual threads for the same and the frames could be displayed
simultaneously without creating a performance lag.
Since I have never worked on multithreading, could anyone please help me.
PFA of the code. (LiveAcquisition code)

Hi,

You could try using PyArray_NewFromDescr NumPy C-API function for creating
nd-array
in function capturing frames.
than doing nested loops to do copy byte by byte. (This could be the
bottleneck)

Hi,
Thank you for the suggestion. I was trying out an example code using
PyArray_NewFromDescr*.* PFA of the code.I compiled the file using :python
setup.py build_ext --inplace.
When compiled I get the following error :
fatal error : numpy/arrayobject.h :No such file or directory.
I would be realy gratefull if you could do the edit in the file I sent in
my first mail.

?

Minutes for python meetup


1) Introduction by Vijay

- reiterated for newcomers on the purpose of the meetup

- networking

- learning etc etc etc

2) Talk#1

by Srini and Nitya Sandhi Checker for Tamil

Talk was in tamil - spell checking in Tamil.


Speaker went through a couple of sample data points with images to
illustrate the problem we were solving.

e.g ?ik?, ?iv? , ?ith? etc addition completely changes the meeting

Syllables in tamil -ka sa ta tha pa ra- some basic rules to check using
open tamil library.


The solution  seems to address only cases where adding the syllable changes
the meaning completely.

Requires  some understanding of tamil grammar is required to appreciate the
solution and understanding of unicode characters for tamil

Otherwise seems to be some basic string formatting - split and
comparison????



We dived right into the code which showed the different rules that were
being considered....



This code is one of the components tamilpesu.us


3) Talk#2

by Naren  - Demystifying Magic Methods

Software consultant @ Tarka Labs



Started with what are magic methods

a) predefined methods for all classes - like __init__ - constructor??

b) eg len() min() max() are magic methods????


How are they implemented

a) eg + operator is a magic method __add__ that is part of every class

'a' + 'b' = 'ab'

is the same as

'a'__add__('b')  = 'ab'

this means you can implement your own __add__ method for your class and the
+ operator will automatically call it when used in conjunction with your
classed

b) e.g 2 transactions - len function , sum function etc

c) __repr__ and __str__ implementation of a class  - str is called  the
print statement? repr is like len(list)

d) __getitem__ makes an object iterable

e) __gt__ and __lt__ implement greater than and lesser than

h) __call__ allows us to make the object callable

i) more than 50 magic methods available in python  - allows you to make
your code pythonic?

j) Caution - over use of magic methods will create very complex - unreadable

www.dudewho.codes/talks




4) Talk#3

by Vijay, Human Learning with Machines - educativ.



Problems with human learning

# memory?

rote does not help understanding

e.g salt experiment in chemistry labs

chemistry lab experiment simulator -

creating games to make learning easy and fun

current android apps and

closed source

require access to camera etc

notifications

distracting ads

Open Source learning frameworks

eudActive8 -  used pygame

- puzzles etc for learning

- extensible allows you to add your own game by programming in python

- e.g game developed sorting words alphabetically (dived into code)

- some pointers

Board extends board game

Create a grid - boxes

create game objects - all the buttons in the various toolbars

Ship is an object that creates a gui icon that can be moved around the
board 1

Doors is an object that creates a gui icon which is a goal position- where
the draggable object must reside finally

Obstacle is an object that creates a gui icon which creates an obstacle on
the board

5) Lightning Talks

#1 Sam - chatops - getting information from a server via chatting to a bot.

use cases

help dev teams to run commands on other servers and stream the output

e.g. erbot server can have ssh logins to your production server and we can
ask over chat to run some commands and send the output back to us

get documentation

#2 Srinivasan - call for collaboration

Requirement for publishers - translation

creating a portal - marketplace for translators and publishers

6) Vote of Thanks

Akshara School for giving us the space

7) A brief talk on the conference

 Hi,
Yes, I was able to make use of  PyArray_NewFromDescr in my code. Storing
into a 3D array has now become a lot faster. Thank you!But the CCD images
stored using this method looks quite different from the ones
acquired earlier.
In the older method at the end of for loop there is incrementing using
 _puc_image
+= aoiStride, I'm not very sure on how to do it with new method. Could you
please take a look at it? I'm not very sure what am I missing here.
?

Hey,
I have written a login script in python for logging into a remote SSH. That
is running successfully. I wrote the code in two ways using thread and
threadpool. But, I'm unable to understand the exact difference of these two
executions. I also want to know which function is more preferred.
(login_thread or login_threadpool). What are the advantages and the
drawbacks?

Hi Rohit,
Threads would be slightly slower than multiprocessing. You might have
issues with sharing variables or GIL. Hence usually multiprocessing is
preferred over threads in python.

So to answer your question, you can use the second method
login_threadpool() shown in the code shared, which uses multiprocessing.

(That being said the first method that uses threads could work just fine
for most purposes)

Regards,
Yacko

Thanks for replying. Are there any issues with using multiprocessing? And
do we need to give the argument for the number of threads in
multiprocessing.pool() function?

I have been using multiprocessing in production for a while and haven't
observed any issues.

Leaving multiprocessing.pool() with no arguments would mean it would take
the number of cpu cores available by default.

Hi ChennaiPy members,

I am really happy to join the community of fellow Python enthusiasts today. 

I registered for the PySangamam Event in the website and was returned to a 405 Method Not Allowed page after the payment. I was worried for a second, but then got the confirmation mail from TownScript right away.

I just wanted to let people know about the issue.

Message-ID: <CA+zm3UPLcX1BowzGMO+bbJPzzmx_qtyqOkhd_Z9n06P3yE90Ng@mail.gmail.com>

Meetup started
Brief intro on the meetup by Vijay.
The purpose of the meetup is to network with other python enthusiasts and
to get inspired by the various talks. The talks also provide some exposure
to the different facets of development and the various problems that are
being tackled. A meetup is not a workshop.


TALK#1
How python is making astrophysical research easier
- by Manjari Bagchi, Professor at IMSc

Used python for her research!!! Wants to generate interest in astrophysics.
Studies cold dead stars that emit radio waves thanks to their magnetic
fields
They are also known neutron stars - about 10 times heavier than the sun -
very dense and regular gravitational physics cannot be used to explain
their gravitational behavior? (not clear how they  are different from black
holes)
Require huge dishes to capture data. Uses python for data analysis

First encounter in 2010 - to analyze pulsar data
Was using unix command line utilities to do this - basically shell
scripting. used the sigproc package developed by her mentor.
Popular library - astropy
There were some interesting asto terms that we were exposed to - right
ascension, galactic center, declination etc

Showed a few examples -
(#1) A file contained latitudes and longitudes of areas of interest which
exhibited strong radio bursts.
Python3 script to read this data and plot the positions on the globe - 3d
earth image projects on to a 2d oval shaped earth on the screen.
Used galpy for plotting(matplotlib?)

(#2) Downloaded some data on a nebula captured by the Hubble telescope.
Python script was used to plot this data.

(#3) Astro plan  - have the coordinate of most of the stars. Based on that
and the longitude, latitude and time in a particular location this module
will tell us if if that star is observable or not, rise time, set time and
a trajectory

(#4) galpy - a module for galactic dynamics


Call for contribution!!!
Project SKA - Square Kilometer Array. Huge sets of telescopes etc in
Australia and South Africa are used to capture data. Entire world is
involved in this project. A lot of programming is required for this. Those
interested can contact her

Link to the National Center for Radio Astrophysics (also contains links to
the SKA Indian team???)

TALK#2
Introduction to NLP & Spacy
- by Vishal  /  Student @SSN

Natural Language Processing
- parsing and mining information from natural language(as it is spoken or
written)

2 libraries in python - NLTK and Spacy
NLTK - created in Stanford purely for educational purposes. Its only for
English.

spaCy
Supports more than 28 languages
Much faster than NLTK.
Developed for the industry
Uses a lot of memory(RAM)

Terms
Corpus - large data set for training and experimenting.
NLTK has a lot of built in corpora

Basic Pre-processing
1) Convert everything to lower case.
2) regex - to extract specific data out (remove dates from a text)
3) Provision to handle special characters and encoding
4) Tokenization break it down to chunks that can be processed
5) Stopword elimination

Language Based Pre-processing
POS - parts of speech - tagging each work as a noun/verb/ajective etc
Stemming and lemmantization - get to the original word
stemming -car cars, car's invariably mean car
lematizer - more useful, allows you to get words that do not have any
common alphabets,but actually mean the same

Dived into code
An example of NLTK and spaCy were shown.
link to the code:




TALK#3
Sultan and Errbot(last months lightning talk expanded upon)
- by Samuel Vijaykumar(Freshworks)
Interacting with server via chat
e.g Ask chatty? - what is the status of a particular build, current load on
the server
ChatOps - currently used for managing infastructure.
- Devops through chatting -but not limited to it, usage limited by your
imagination.
Before developing, requirements were
# Conversational - not yet reached NLP
# Operational - manage operations based on user rights and security
# Extensible -
# Pythonic -
Demo -
create a slack channel, a plugin will allow you to execute your commands
errbot to create a bot.
sultan python library to ssh to servers and execute commands/ also create
agents that act on your behalf?
bot configuration
1) BACK END - POINTS TO  SLACK
2) BOT_IDENTITY -  POINTS TO THE SLACK CHANNEL?



Lightning Talk by #Prasanth   for microservices - lambda on aws  and an
alternative project called pywren to help with scaling.

Subject: [Chennaipy] Minutes of May meetup: corrections in the astro
 talk.
Message-ID: <CAHAx3-fi_+YHSTOUuvi1x3=zFE4GUew4HP9GHJ7Za0Z1d=GcMA@mail.gmail.com>

Hi all,

Thanks for inviting me to give a talk in your meet-up, and also thanks to
Vivek for a summary of an astrophysics talk!
However, I would like to clarify a few issues (kept with "?") with Vivek's
summary:


> 1) They are also known neutron stars - about 10 times heavier than the sun
> - very dense and regular gravitational physics cannot be used to explain

 Neutron stars are not 10 times heavier than the sun. They are 1 to 2 times
of the solar mass. They are formed when stars 10 times or more die (a
significant amount of mass is lost during the death or the supernova
explosion).

Yes, galpy did all the calculations but the plotting window was called by
matplotlib.

 Not me, I am basically a theoretician. Interested people might think to
contact relevant persons in NCRA.

 Yes, but the team involves theoreticians also.

 Thanks and regards,
Manjari

Hi Manjari,
Thanks for the clarification. And thanks for the talk as well. You 
definitely kindled the interest in astronomy in all of us. :-)

Regards,
Vijay
