Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
2. What is Django
Django is a MVC like framework ( Django
community call it as MTV - Model, View, Template
) written in pure python
Django can be used with databases like
Postgresql, MySQL, sqlite, MongoDB, Oracle etc..
3. Who are using Django
Mozilla ( support.mozilla.com, addons.mozilla.org )
Google ( developers.google.com, app engine cloud sql
)
Disqus
Pinterest
Instagram
bitbucket
newyorktimes.com (represent)
washingtonpost.com
guardian.co.uk
developer.vodafone.com
nationalgeographic.com
4. Creating a django project
Start a new project from
django-admin.py startproject projectname
It will create project folders in the following
structure
projectname/
manage.py
projectname/
__init__.py
settings.py
urls.py
wsgi.py
6. settings.py
This contains all the settings related to the
project. Like DB username-password-connection-
port, middlewares, logs, dev
settings, media path etc.
The settings.py file is used as default
configuration file while running the server. If you
have some other settings file then you can tell
the server to use that by setting the environment
vairable DJANGO_SETTINGS_MODULE
7. urls.py
• URL patterns are definied in this file.
• URL patterns will be made up of regular
expressions of the url patterns.
• The function/view that needs to be called are
mapped here.
• Best Practice : Maintain a urls.py inside each app
to avoid the global urls.py mess
8. A typical urls mapping looks like this
from django.conf.urls import patterns, url
urlpatterns += patterns('',
urlpatterns = (
url(r'^$', views.index, name='index'),
)
9. views.py
The request lands here after the url requested is mapped to
a view through middlewares.
There are two types of view. That a user can opt for
depending on the requirement.
1. Function Based View
2. Classbased view
Function based views are normal python functions that take
request and curresponding custom parameter if any.
Class Based views are the special views that is required to
be inheriting the django's predefined view/any other class
that satisfy the condition to map the url to a class based
view ( Better to inherit the view class given by django :) )
10. • There are lot of built in views that can be used
accordingly. ( e.g. listview - if you want just to list
the objects of a model that satisfy a queryset )
• url definition will take function based view ( FBV
) as second argument. This will make the view
function gets called for that url. Where as Class
based view's as_view() function should be feed
to url definition. The reason is given below.
• Class Based Views ( CBV ) has the intelligence
to find the method used in request ( get, post or
any other ) and dispatche the data come along
with the request to curresonding method.
11. • Each view must return a response or raise the relevant
exeption if any.
• response can contain the django template, file, JSON
objects or even just HTTP Status codes.
12. A typical Django FBV would look like this
from django.http import HttpResponse
import datetime
def current_datetime(request):
now = datetime.datetime.now()
html = "<html><body>Its now %s</body></html>"
% now
return HttpResponse(html)
13. A typical Django CBV would look like this
import datetime
from django.http import HttpResponse
from django.views.generic import View
class ShowDateView(View):
def get(request):
now = datetime.datetime.now()
html = "<html><body>Its now %s</body></html>"
% now
return HttpResponse(html)
14. models.py
Models.py file is the place to put the details about
the DB tables that we need in our app.
Models can be imagined as DB Table - definition
written in python :)
Models are the normal python classes that inherit
from the Django "Model" class found in
django.db.models module.
The class attributes/member-variables defines the
columns and data type of their curresponding db
tables.
15. • models will have thier own "manager" objects
that will be used to query the table.
• Django ORM provides the "query functions" in
each models through thier "manager" objects.
• Each model object will have their save() method
to save the model "instance" into database.
• models have built in validators which will validate
the model object values against their datatype
and constraints.
16. A typical django model would look like
from django.db import models
class UserProfile(models.Model):
first_name = models.CharField(max_lenght=10)
last_name = models.CharField(max_lenght=10)
phone_number = models.IntegerField(null=True)
17. Availble Built in Fields in Django models
AutoField
BigIntegerField
BooleanField
CharField
CommaSeparatedIntegerField
DateField
DateTimeField
DecimalField
EmailField
FileField
18. forms.py
Django forms which is used to process web form
data are similar to django model classes. But
django froms deal with the incoming data from
client rather than database.
Similar to Django models django forms are python
classes inheriting from Django's django.form
module
19. A django form declaration would look like
from django import forms
class LoginForm(forms.Form):
username = forms.CharField(max_length=12)
password = forms.CharField(max_lenght=12, att)
20. Django Forms built in Fields
BooleanFieldCharField ChoiceField
DateField DateTimeField
EmailField FileField
FloatField ImageField
IPAddressField GenericIPAddressField
TypedMultipleChoiceField NullBooleanField
SlugField TimeField
TypedChoiceField DecimalField
FilePathField IntegerField
MultipleChoiceField RegexField
URLField
21. templates
Django templates are the files (Usually HTML ) which allow
us to insert the django variables inside them and write very
minimalistic processing like iterating over a loop, trimming
the string, adding integers inside them etc.
Django templates are designed to make it reusable. Like a
class, you can inherite a template and override the portions
of it.
Django template engine comes with built in tags and filters
which can be used to process the data before rendering.
Even django allows you to create your own custom tags
and filters. So that you can define your custom behaviors in
the template.
22. Django templates should be written in such a way that only
rendering process will be held in that. No complex logical
algorithm shoul be handled inside the templates.
Django template are designed such that it uses the less of
programming language, and more of the designing part so
that any web designer knowing only creating
HTML/CSS/Javascript can develop it without having the
exposure to the python.
23. Django Principles
DRY ( Don't Repeat Yourself )
Loose Coupling
Less Code
Explicit is better than implicit
Infinite flexibility in url
Separate logic from presentation
Be decoupled from HTML
24. Benifits/Pros of using Django
Easy to understand and easily maintainable
code
Write less do more with python-django
combination.
Lot of opensource plugins available that can be
used along with django. You just need to
import and use it in your code.
25. Django has lot of built-ins which are more
commonly needed functionalities in a web app
along with additional goodies.
• User authentication and password management
• Pagination
• Form-Model validation
• Caching
• Admin Panel
• Session management
• Protection via clickjacking and cross site
