A class is a code template for creating objects. Objects have member variables and have behaviour associated with them. In python a class is created by the keyword class.
An object is created using the constructor of the class. This object will then be called the instance of the class.

Hands-on Demonstrations
All data values in Python are encapsulated in relevant object classes. Everything in Python is an object and every object has an identity, a type, and a value. Like another object-oriented language such as Java or C++, there are several data types which are built into Python. Extension modules which are written in C, Java, or other languages can define additional types.
To determine a variable's type in Python you can use the type() function. The value of some objects can be changed. Objects whose value can be changed are called mutable and objects whose value is unchangeable (once they are created) are called immutable.

As the amount of metrics, software that produce and process them, and people involved in them continue to increase, we need better ways to organize them, to make them self-describing, and do so in a way that is consistent. Leveraging this, we can then automatically build graphs and dashboards, given a query that represents an information need, even for complicated cases. We can build richer visualizations, alerting and fault detection. This talk will introduce the concepts and related tools, demonstrate possibilities using the Graph-Explorer interface, and lay the groundwork for future work.
Do you gather metrics from your application? Can you combine them and easily generate custom graphs out of them? Can your developers measure whatever they want at any point of your application without breaking it or making it slower?
In our next itnig friday, Víctor Martínez will show us how easy it is to roll on your own Graphite installation and how to use Etsy's statsd collector to flush your metrics. You will learn what Graphite is, how all of its components work, how to get your real time&historic metrics into Carbon, Graphite's database, and how to plot them in different manners. Víctor will show us some Graphite dashboards, alternative statds implementations, detailed common Graphite configuration gotchas, design limitations and how to deal with them.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
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.

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

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.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
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.

Python DateTime modules:
In this article, we will see the Python DateTime module. We will learn how to create
current time, how to calculate the time gap and how to produce time difference?
According to Python docs
“The python DateTime module supplies classes for manipulating dates and times in
both simple and complex ways”.
So, python DateTime modules contain several classes. Let us discuss one by one.
Python DateTime Modules — The Datetime.datetime
Let us discuss the useful methods of the DateTime.datetime class.

But if you provide time zone then the datetime.datetime.now() returns the current
time according to time zone.
>>>
>>> import pytz
>>> pytz.utc
>>> print datetime.datetime.now(pytz.utc)
2018–08–19 17:23:34.614000+00:00
If you provide the time zone information in string then interpreter throws an error.
>>> print datetime.datetime.now(‘US/Eastern’)
Traceback (most recent call last):
File “<stdin>”, line 1, in <module>

datetime.strptime(date_string, format)
The datetime.strptime(date_string, format) take date_string and format as argument
and returns the datetime object. As shown below.
>>> import datetime
>>> datetime.datetime.strptime(“May 12 2018”, “%B %d %Y”)
datetime.datetime(2018, 5, 12, 0, 0)
>>> print datetime.datetime.strptime(“May 12 2018 13:03:29”, “%B %d %Y
%H:%M:%S”)
2018–05–12 13:03:29
Strftime(format)
The strftime(format) is used generate the formatted date from datetime object.
>>> print datetime.datetime.now().strftime(“%d %b, %Y”)
22 Aug, 2018

Ctime()
Converts the seconds to a 24-character string of the following form: “Mon Jun 20
23:21:05 1994”.
>>> datetime.datetime.now().ctime()
‘Thu Aug 23 00:07:28 2018’
>>>
isoformat()
Return a string representing the date in ISO 8601 format, ‘YYYY-MM-DD’. For example
>>> datetime.datetime.now().isoformat()
‘2018–08–23T00:11:32.393000’

datetime.date
Let us discuss new class datetime.date.
datetime.today()
The method returns today’s date. For example.
>>> import datetime
>>> print datetime.datetime.today()
2018–08–23 23:18:22.044000
>>>
datetime.date.fromtimestamp()
The method converts Unix stamp or epoch to date.
For example
>>> print datetime.date.fromtimestamp(0)
1970–01–01
9. Copyright @ 2018 Learntek. All Rights Reserved. 9
>>>
>>> import time
>>> time.time()
1535047001.754
>>>
>>> print
datetime.date.fromtimestamp(1535047001.754)
2018–08–23

datetime.timedelta
The class datetime.timedelta is used to create time difference between two dates
or times.
The class DateTime.timedelta takes keyworded arguments. According to py docs
All arguments are optional and default to 0. Arguments may be ints, longs, or floats,
and may be positive or negative.
Only days, seconds and microseconds are stored internally. Arguments are
converted to those units:
Let us create different-2 exercises for delta.
11. Copyright @ 2018 Learntek. All Rights Reserved. 11
Let us create time delta of 10 seconds.
>>> import datetime
>>> delta1=datetime.timedelta(seconds=10)
Subtract the time delta to the current time.
>>> now1 = datetime.datetime.now()
>>> now1
datetime.datetime(2018, 8, 24, 22, 53, 56, 488000)
>>> print now1
2018–08–24 22:53:56.488000
12. >>> print now1 — delta1
2018–08–24 22:53:46.488000
Add the time delta to the current time.
>>> print now1 + delta1
2018–08–24 22:54:06.488000
>>>
Let us do one complete exercise.
1. Create a Unix time means an epoch of 10 days ago.
2. Create a Unix time 10 days later.
Let us do step by step
>>> import datetime
>>> import time
Copyright @ 2018 Learntek. All Rights Reserved.
13. Create two deltas for time difference one for 10 days ago and one for 10 days later.
>>> delta1=datetime.timedelta(days=10)
>>> delta2=datetime.timedelta(days=-10)
Add both the deltas to the current time.
>>> now1 = datetime.datetime.now()
>>> ten_days_ago = now1+delta2
>>>
>>> ten_days_later = now1+delta1
>>>
>>> print ten_days_ago
2018–08–14 23:09:04.861000
>>>
Copyright @ 2018 Learntek. All Rights Reserved.
14. >>> print ten_days_later
2018–09–03 23:09:04.861000
>>>
In order to remove floating point use, strftime method has been used.
>>> date1 = ten_days_ago.strftime( “%Y-%m-%d %H:%M:%S” )
>>> date1
‘2018–08–14 23:09:04’
By the use time module, the Unix time or epochs have been created.
>>> int(time.mktime(time.strptime(date1, ‘%Y-%m-%d %H:%M:%S’) ) )
1534268344
>>>
>>> date2 = ten_days_later.strftime(“%Y-%m-%d %H:%M:%S”)
>>>

Python Calendar module
Now we’ll use calendar module to print the calendar of a particular month. In order to
print a particular month, calendar.month(year, month) would be used as shown below.
>>> import calendar
>>> print calendar.month(2018,8)
August 2018
Mo Tu We Th Fr Sa Su
1 2 3 4 5
6 7 8 9 10 11 12
16. 13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30 31
>>>
Let us print the calendar for the 2018 year.
>>> import calendar
>>> print calendar.calendar(2018)
Consider if you want to find out whether a particular year is a leap year or not.
You can use calendar.isleap(year)
See the example below.
>>> calendar.isleap( 2000 )
True
Copyright @ 2018 Learntek. All Rights Reserved.
17. >>> calendar.isleap( 2001 )
False
>>> calendar.isleap( 2016 )
True
>>> calendar.isleap( 1992 )
Consider you want to find out the number of leap year in the range of y1 to y2.
See the example below.
>>> calendar.leapdays( 1992 , 2016 )
6
>>> calendar.leapdays( 1991 , 2015 )
6
>>>
Copyright @ 2018 Learntek. All Rights Reserved.
18. Copyright @ 2018 Learntek. All Rights Reserved.
The last year is not included in the range.
Consider you might want to know the time of the different countries.
By default, time-related modules return the time according
to your time zone. Let see how to get the time of the different country
>>> import datetime
>>> import pytz
Let us check the current time of ‘US/Eastern’.
>>> print datetime.datetime.now(pytz.timezone(‘US/Eastern’))
2018–08–25 14:25:34.712000–04:00
>>>
Let us check the current time of India.
19. Copyright @ 2018 Learntek. All Rights Reserved.
>>> print datetime.datetime.now(pytz.timezone(‘Asia/Kolkata’))
2018–08–25 23:56:40.564000+05:30
If you don’t know the name of the timezone, then you can use search the
timezone using the country name.
>>> pytz.country_timezones.get(“NZ”)
[u’Pacific/Auckland’, u’Pacific/Chatham’]
>>>
New Zealand has two timezones.
Let us check the name of the timezone of India
20. >>> pytz.country_timezones.get(“IN”)
[u’Asia/Kolkata’]
>>>
pytz.country_timezones.keys()
The above line returns the list of country abbreviations as a shown example below.
[u’BD’, u’BE’, u’BF’, u’BG’, u’BA’, u’BB’, u’WF’, u’BL’, u’BM’, u’BN’, u’BO’, u’BH’, u’BI’, u’BJ’,
u’BT’, u’JM’, u’BW’, u’WS’, u’BQ’, u’BR’, u’BS’, u’JE’, u’BY’ So on…….]
If you want to be confirmed whether ‘abbreviation IN’ belongs to India or other
countries like Iran. You can use Syntax pytz.country_names.get( ‘IN’ )
>>> print (pytz.country_names.get( ‘IN’ ) )
India
if you want to check all the countries and its abbreviations. Use the following piece of
code.
Copyright @ 2018 Learntek. All Rights Reserved.
21. >>> for each in pytz.country_names.iteritems():
… print each
…
(u’BD’, u’Bangladesh’)
(u’BE’, u’Belgium’)
(u’BF’, u’Burkina Faso’)
(u’BG’, u’Bulgaria’)
So, on.
