Socket.IO

Connect

 

var io = require(‘socket.io’).listen(80); io.sockets.on(‘connection’, function (socket) { socket.on(‘message’, function (data) { console.log(data); }); });

• on message need to parse
• and on send stringify.

Managing Log Level

 

io.set(‘log level’, 1);

Maintaining connection of same user with socket.io in multiple tab of Browser

 

• use the same port for both node.js and socket.io server by passing server to listen method of socket.io

Class

__init__(self)

The instantiation operation (“calling” a class object) creates an empty object. Many classes like to create objects with instances customized to a specific initial state. Therefore a class may define a special method named __init__(), like this:
def __init__(self):
self.data = []

When a class defines an __init__() method, class instantiation automatically invokes __init__() for the newly-created class instance. So in this example, a new, initialized instance can be obtained by:

Ref :http://docs.python.org/tutorial/classes.html

Inheritance

class DerivedClassName(BaseClassName): <statement-1> . . . <statement-N>

Multiple Inheritance

 

class DerivedClassName(Base1, Base2, Base3): <statement-1> . . . <statement-N>

Super

For new-style classes, the method resolution order changes dynamically to support cooperative calls to super(). This approach is known in some other multiple-inheritance languages as call-next-method and is more powerful than the super call found in single-inheritance languages.

*args and **kwargs

Putting *args and/or **kwargs as the last items in your function definition’s argument list allows that function to accept an arbitrary number of anonymous and/or keyword arguments.
For example, if you wanted to write a function that returned the sum of all its arguments, no matter how many you supply, you could write it like this:

def sum(*args): return sum(args)

It’s probably more commonly used in object-oriented programming, when you’re overriding a function, and want to call the original function with whatever arguments the user passes in.
You don’t actually have to call them args and kwargs, that’s just a convention. It’s the * and ** that do the magic.

class Super( object ): def __init__( self, this, that ): self.this = this self.that = that class Sub( Super ): def __init__( self, myStuff, *args, **kw ): super( Sub, self ).__init__( *args, **kw ) self.myStuff= myStuff x= Super( 2.7, 3.1 ) y= Sub( “green”, 7, 6 )

This way Sub doesn’t really know (or care) what the superclass initialization is. Should you realize that you need to change the superclass, you can fix things without having to sweat the details in each subclass.

you can also call functions with *mylist and **mydict to unpack positional and keyword arguments:

def foo(a, b, c, d): print a, b, c, d l = [0, 1] d = {“d”:3, “c”:2} foo(*l, **d)

Will print: 0 1 2 3

Handling Exceptions¶

 

while True: …    try: …        x = int(raw_input(“Please enter a number: “)) …        break …    except ValueError: …        print “Oops!  That was no valid number.  Try again…”

for arg in sys.argv[1:]: try: f = open(arg, ‘r’) except IOError: print ‘cannot open’, arg else: print arg, ‘has’, len(f.readlines()), ‘lines’ f.close()

Raise

The raise statement allows the programmer to force a specified exception to occur. For example:

getattr

Import

__init__.py:

An empty file that tells Python that this directory should be considered a Python package. (Readmore about packages in the official Python docs if you’re a Python beginner.)

Replace into

 

Please note that REPLACE INTO is a much slower performer than an UPDATE statement. Keep in mind that a REPLACE INTO requires a test on the keys, and if a matching unique key is found on any or all columns, a DELETE FROM is executed, then an INSERT is executed. There’s a lot of management of rows involved in this, and if you’re doing it frequently, you’ll hurt your performance unless you simply cannot do with any other syntax. The only time when I can see where you’d actually need a REPLACE INTO is when you have multiple unique constraints on a table, and need to drop any rows that would match any of the constraints. Then REPLACE INTO becomes more efficient from DELETE FROM… INSERT INTO…

http://www.webs05.com/2008/04/06/mysql-difference-between-update-and-replace.html

INSERT INTO user (userid,birthday,first_name,last_name) VALUES (1234,’1980-03-07′,’Joe’,’Smith’) ON DUPLICATE KEY UPDATE birthday = ‘1980-03-07’, first_name = ‘Joe’, last_name = ‘Smith’;

Programming

 

• The older I get, the more I believe that the only way to become a better programmer is by not programming. You have to come up for air, put down the compiler for a moment, and take stock of what you’re really doing. Code is important, but it’s a small part of the overall process.
• What I am proposing is that we spend less time coding and more time developing skills in other areas that complement our coding skills. Become a better writer. Become a better speaker. Improve your personal skills. Participate in the community.
• Programming, like all writing, is just another form of communication. Writing code that the compiler understands is easy. Writing code that other people understand is far more difficult.
• You won’t– you cannot– become a better programmer through sheer force of programming alone. You can only complement and enhance your existing programming skills by branching out. Learn about your users. Learn about the industry. Learn about your business.
• The more things you are interested in, the better your work will be.
• Try to spend some time talking to people instead of the compiler. That’s how you distinguish yourself from your peers. And that’s ultimately how you become a better software developer, too.
• Ideally, you’d write code, and then write or talk about the code in a way that inspires and illuminates other people.
• And even if productivity isn’t an issue, the inevitable tides of our economy will be. You will at some point in your career be dealing with a tight job market. And it’s not your technological skills that will determine how well you succeed at those times.
• It’s your personal skills that will count. How well do you communicate? You should know how to present your ideas both to individuals and small groups. Can you write clearly and somewhat grammatically. Do you come across as confident in yourself and your abilities? Do you have leadership skills (that often translate into management skills)? Are you responsible? Are you a nice person to have around (or at least not completely repulsive)? Yes, there are those who are so technologically brilliant they can get away with caring just about technology, but for most of us these other skills are essential.
• So, as you go off to college, don’t let your technical classes get in the way of getting a good education. Take a writing class. Take a class or get involved in an activity that forces you to do some public speaking. Do some drama or improv. Join a club. Do some volunteer work. Do some tutoring. This kind of experience will have long term benefits to your career that you wouldn’t believe.

back bone

Backbone.js

 

To declare User model :

 

App.Backbone.User = Backbone.Model.extend();

In above line i am assigning the Backbone model to App.Backbone.User variable .

To declare User Collection :

 

• we assign the model.

 

• we bind the add and remove event to collection

App.Backbone.Users = Backbone.Collection.extend({ model : App.Backbone.User, initialize: function(models, args) { this.bind(‘add’, this.renderone); this.bind(‘remove’, this.destroy); }, renderone:function(user){ var view = new App.Backbone.UserView({model: user}); view.render(); var view = new App.Backbone.UserCardView({model: user}); view.render(); }, destroy:function(user){ $(user.view.el).remove(); } });

• add event is bind with renderone function
• remove event with destroy funciton.
• we can render more than one view while adding .

initialise the Collection  of user

App.Users = new App.Backbone.Users();

add user in collection.

 

var data ={id:’rahul’, username:rahul,firstname:’Rahul’}; App.Users.add(data);

at this point automatically view will be rendered as we bind the add event in collection above.

remove a model

 

App.Users.remove(App.Users.get(‘rahul’));

so on remove view will also remove

User View

 

App.Backbone.UserView = Backbone.View.extend({ tagName: ‘li’, className: ‘pp-entry group’, template :_.template(‘<h6><%=username%></h6>’), // very simple can be complex initialize: function() { _.bindAll(this, ‘render’); this.model.bind(‘change’, this.render); // on any change in model the view will render again this.model.view = this; }, events:{ “click .addtowallet”:”addlinktowallet”, }, // Re-render the contents of the Card item. render: function() { $(this.el).append(this.templatedetails(this.model.toJSON())); } });

 

• model is binded with the change event , so on every change in model will render the view again automatically.

update a model

var data ={id:’rahul’, username:rahul,firstname:’Rahul’,lastname:’mehta’}; App.Users.get(‘rahul’).set(data);

• the view also render due to change event in view.

Channels

 

• for each gib there is two channel ,  ouside and inside.
• the structure of  channels in redis : the channels has users key , which is the comma seperated users list which are presents in the channel
• so for checking we need to split the comma separated list into an array  and perform the operations and then again save the comma separated list.

 

Get

 

• keys channels*
• hgetall channels.7-O

Delete

 

• deleting particular channel

 

• del channels.7-O

Django Admin

One of the most powerful parts of Django is the automatic admin interface. It reads metadata in your model to provide a powerful and production-ready interface that content producers can immediately use to start adding content to the site. In this document, we discuss how to activate, use and customize Django’s admin interface.

• Adding custom validation to the admin.

Django Forms

Form.cleaned_data

Each field in a Form class is responsible not only for validating data, but also for “cleaning” it — normalizing it to a consistent format. This is a nice feature, because it allows data for a particular field to be input in a variety of ways, always resulting in consistent output.

>>> data = {‘subject’: ‘hello’, …        ‘message’: ‘Hi there’, …        ‘sender’: ‘foo@example.com’, …        ‘cc_myself’: True} >>> f = ContactForm(data) >>> f.is_valid() True >>> f.cleaned_data {‘cc_myself’: True, ‘message’: u’Hi there’, ‘sender’: u’foo@example.com’, ‘subject’: u’hello’}

Model.__unicode__()¶

he __unicode__() method is called whenever you call unicode() on an object. Django uses unicode(obj) (or the related function, str(obj)) in a number of places. Most notably, to display an object in the Django admin site and as the value inserted into a template when it displays an object. Thus, you should always return a nice, human-readable representation of the model from the __unicode__() method.

class Person(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50)def __unicode__(self): return u’%s %s’ % (self.first_name, self.last_name)

softw. business

a) You are targetting a new or underserved niche market. Old or saturated market means a lot of powerful competitors fighting for same customers.
b) You will be providing a new, cheap or better solution than existing ones. If not why will anyone buy your solution?
c) Using new distribution channels to provide solutions more efficiently( e.g., bookmyshow, IRCTC use internet to distribute movie and railway tickets)
d) There is demand of your solution in market.
e) The idea is feasible(you have or can arrange the capital, man power and technical/business skills to implement your idea)
f) Your idea is profitable. i.e. You earn more than you expend.

Think about your idea, take feedback about it from others in your social circle, improve and finalize it.

2. Startup Team/ Board of Advisors – The next logical step will be to look for co-founders who can compliment to your skills and are as enthusiastic about your idea as you are. It is good to have a technology geek, a design expert and a marketing guy in your team. Also, form a board of advisors (experienced industry experts who will share their advice when needed).

3. Create a business plan – a detailed one for your own use and a short customized one if needed for raising capital. Remember that a good plan is one that is flexible to change coz most of the time it will be never done exactly as planned.

4. Develop Product prototype(if hardware product) or beta version(if software) of your product (If possible in garage. :p).

5. Register your company. Hire a Charted Accountant and he will do it for you.

Simply put, chances are you won’t think of the next big thing. Even if you do, you probably won’t have the resources, experience, or contacts, to turn your idea into billions. We were not expecting miracles but were on the lookout many months in advance. One thing we learned while reading Founders At Work is that many software startups are formed without the faintest clue of what the product/service will be. The most important part of the company is not the idea but the people. A small and closely knit team of people who’ve worked together in the past is a recipe for success, regardless of the idea. Indeed, execution is key! Partnering with people who have a track record of bringing ideas to reality is, in our opinion, the most important part of the business.

We are very happy that we did not wait on having a brilliant breakthrough idea and started our company immediately. We evaluated opportunities and picked the one that made the most business sense, knowing we can adapt along the way. Having made the plunge early in our careers, we felt we didn’t have anything to lose because we didn’t have that many constraints such as leaving a high paying job, a mortgage and student loans to pay, kids to feed, etc. The more acquainted you get with stable employment, the harder it is to leave. Still, it is worth mentioning that while we were very comfortable with our technical skills, our network of contacts is not as large as it would have been if we had been under someone else’s employment for 5-10 years. On the bright side, we don’t have 10 year of accumulated bitterness to carry around and we’re in the best phase of our development careers (from a production standpoint).
