ONLINE CAR SERVICING SYSTEM PROJECT REPORT.pdfKamal Acharya
Our vision is to make ONLINE CAR SERVICING SYSTEM is needed for the country as technology grows fast in the world. The purpose is to develop this project to provide a better solution to the problems that the customers faces. This website will provide customers to reserve their car services from their home or from office. Customer feels hard to send their car for the service, either they need to reserve using mail system or walk in to send their car for service.
At the end of these project, a prototype of justified system will develop which will provide a solution for the identify problem to improve the organizations revenue and performance. This system will be web based system where it is able to conduct an overall process of online registration and bookings too. The data will be stored in keep as privacy for each customer who has register.
The Distributed Banking System is a client-server program which is implemented using RMI (Remote Method Invocation). The server manages all users’ account information.

The retail sales industry has undergone some noticeable transition in the array of payment methods over the years.
It is imperative that an innovative payment solution is introduced to replace an cashier checkout system especially when there is growing demand for it.
Assuredly, the addition of a mobile self-checkout application in industry will be more prominent in the next few years.
The aim is to develop a mobile self-checkout application for a retail store of a client.
Objective -
Develop a Mobile application having a barcode scanner facility, it will be used to scan the barcode given in product and add it to the cart.
Make the payment with multiple payments methods easily with app itself.
Once payment is done it give alert or message to store owner
Apart from this app will access current location of store and give the products details according to that particular store only.
Application Domain -
Through this application we can easy people’s life by not wasting their time to go through the cashier checkout point, and the product review are also there in the application.
There will be a great impact of this application as It helps in a great measure cut off the long line at the cashier checkout points
which can be frustrating at times for both customers and the cashier.
In this talk we will explore how to organize component-centric code splitting with server side rendering and universal data fetching in React, when your application becomes large enough.
Talk description: When you have a large enough application, a single large bundle with all of your code becomes a problem for startup time. You need to start breaking your app into separate bundles and load them dynamically when needed.
How to split a single bundle into multiple is a well-solved problem with tools like Browserify and Webpack.
But now you need to find places in your application where you can decide to split off into another bundle and load it asynchronously. You also need a way to communicate between server and client, and organize server side rendering and implement universal data fetching for your application.
Even React Router team failed with this task
“We’ve tried and failed a couple of times”(https://reacttraining.com/react-router/web/guides/code-splitting/code-splitting-server-rendering)
I will show you how to solve this problem, we will use a great library called React Loadable.
Also, we will look at some solutions which you can achieve with React Router v4 and why they are not the best one.
For this talk, you will need some knowledge in React, Babel (ES6), Node, Webpack 2, Redux, and little bit React Router v4.
These are the slides from our January presentation of our in-Flash payment solution.
It gives a brief overview of Social Gold as well as a technical presentation that shows how to integrate the our in-Flash solution with your Flash game.
Enjoy!
in this presentation we give a brief intro to Social Gold, an overview of the in-flash solution architecture followed by a step by step integration example.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Creating an Uber Clone - Part XXXI - Transcript.pdf
1. Creating an Uber Clone - Part XXXI
The last two "big ticket items" are billing and social login. I won't implement them with adherence to the way they were implemented by Uber. I want to keep both of
these features simple as they are both very volatile. Features and requirements within both of these API's can change literally overnight.
9. @Service
public class BraintreeService {
private final static BraintreeGateway gateway = new BraintreeGateway(
Environment.SANDBOX,
"your_merchant_id",
"your_public_key",
"your_private_key"
);
@Autowired
private RideRepository rides;
public String getClientToken() {
return gateway.clientToken().generate();
}
public void saveNonce(long rideId, String nonce) {
Ride r = rides.findOne(rideId);
r.setNonce(nonce);
rides.save(r);
}
public void pay(BigDecimal amount, String nonce) {
TransactionRequest requestT = new TransactionRequest()
.amount(amount)
.paymentMethodNonce(nonce)
.options()
.submitForSettlement(true)
.done();
}
}
BraintreeService
Next we add a `BraintreeService` class which is remarkably simple.
These values should be updated from Braintree and SANDBOX should be updated to production once everything is working
10. @Service
public class BraintreeService {
private final static BraintreeGateway gateway = new BraintreeGateway(
Environment.SANDBOX,
"your_merchant_id",
"your_public_key",
"your_private_key"
);
@Autowired
private RideRepository rides;
public String getClientToken() {
return gateway.clientToken().generate();
}
public void saveNonce(long rideId, String nonce) {
Ride r = rides.findOne(rideId);
r.setNonce(nonce);
rides.save(r);
}
public void pay(BigDecimal amount, String nonce) {
TransactionRequest requestT = new TransactionRequest()
.amount(amount)
.paymentMethodNonce(nonce)
.options()
.submitForSettlement(true)
.done();
}
}
BraintreeService
This is the client token that we use to identify the transaction. Notice we generate a new one for every request
11. @Service
public class BraintreeService {
private final static BraintreeGateway gateway = new BraintreeGateway(
Environment.SANDBOX,
"your_merchant_id",
"your_public_key",
"your_private_key"
);
@Autowired
private RideRepository rides;
public String getClientToken() {
return gateway.clientToken().generate();
}
public void saveNonce(long rideId, String nonce) {
Ride r = rides.findOne(rideId);
r.setNonce(nonce);
rides.save(r);
}
public void pay(BigDecimal amount, String nonce) {
TransactionRequest requestT = new TransactionRequest()
.amount(amount)
.paymentMethodNonce(nonce)
.options()
.submitForSettlement(true)
.done();
}
}
BraintreeService
We save the nonce into the Ride object. This assumes payment authorization happens before the ride is completed. Once the ride is finished the nonce is instantly
available to do perform the charge
12. @Controller
@RequestMapping("/pay")
public class BraintreeWebservice {
@Autowired
private BraintreeService payment;
@RequestMapping(method=RequestMethod.GET,value = "/token")
public @ResponseBody String getClientToken(long id) {
return payment.getClientToken();
}
@RequestMapping(method=RequestMethod.GET,value="/nonce")
public @ResponseBody String nonce(
@RequestParam(name="ride", required = true) long rideId,
@RequestParam(name="nonce", required = true) String nonce) {
payment.saveNonce(rideId, nonce);
return "OK";
}
}
BraintreeWebservice
Before we proceed further the obvious next step is the webservice to match.
It's mostly trivial but I'd like to point out a small nuance: pay isn't mapped. We invoke pay in the server so we don't need to expose it to the client side.
13. private String nonce;
public String getNonce() {
return nonce;
}
public void setNonce(String nonce) {
this.nonce = nonce;
}
Ride
That code required some unexpected changes which I will get to shortly. The first change was pretty predictable though. We just had to add a nonce field to the Ride
class
14. private Long currentRide;
public Long getCurrentRide() {
return currentRide;
}
public void setCurrentRide(Long currentRide) {
this.currentRide = currentRide;
}
Ride
Here's the part I didn't expect. I need to add the ride id to the User object. A driver has a reference to the Ride object which is why we didn't need this up until now.
However, when the user tries to pay he can't set this anywhere else...
Unfortunately there is no other place where the nonce would fit. Since it's transient we can't add it to the User as we'd want some logging. The Ride object is the "right
place" for the nonce.
15. public long acceptRide(String token, long userId) {
User driver = users.findByAuthToken(token).get(0);
User passenger = users.findOne(userId);
if(!passenger.isHailing()) {
throw new RuntimeException("Not hailing");
}
passenger.setHailing(false);
passenger.setAssignedUser(driver.getId());
driver.setAssignedUser(userId);
Ride r = new Ride();
r.setDriver(driver);
r.setPassenger(passenger);
rides.save(r);
driver.setCurrentRide(r.getId());
passenger.setCurrentRide(r.getId());
users.save(driver);
users.save(passenger);
return r.getId();
}
acceptRide
To get this to work I had to make a few changes to the acceptRide method.
I added the ride reference to both the driver and passenger for future reference.
16. public long acceptRide(String token, long userId) {
User driver = users.findByAuthToken(token).get(0);
User passenger = users.findOne(userId);
if(!passenger.isHailing()) {
throw new RuntimeException("Not hailing");
}
passenger.setHailing(false);
passenger.setAssignedUser(driver.getId());
driver.setAssignedUser(userId);
Ride r = new Ride();
r.setDriver(driver);
r.setPassenger(passenger);
rides.save(r);
driver.setCurrentRide(r.getId());
passenger.setCurrentRide(r.getId());
users.save(driver);
users.save(passenger);
return r.getId();
}
acceptRide
I moved these lines downward because the ride ID will only be available after the rides.save() call
17. public void finishRide(long rideId) {
Ride current = rides.findOne(rideId);
current.setFinished(true);
if(current.isStarted() && current.getNonce() != null) {
Set<Waypoint> s = current.getRoute();
Iterator<Waypoint> i = s.iterator();
if(i.hasNext()) {
long startTime = i.next().getTime();
long endTime = -1;
while(i.hasNext()) {
endTime = i.next().getTime();
}
if(endTime > -1) {
BigDecimal cost = BigDecimal.valueOf(endTime - startTime).
divide(BigDecimal.valueOf(60000));
current.setCost(cost);
payments.pay(current.getCost(), current.getNonce());
}
}
}
rides.save(current);
}
finishRide
Since payment is handled on the server side we can go directly to it even before we do the client side... I've decided to do this in the finishRide method.
A ride that was finished before it was started is effectively canceled. A ride without a nonce can't be charged
18. public void finishRide(long rideId) {
Ride current = rides.findOne(rideId);
current.setFinished(true);
if(current.isStarted() && current.getNonce() != null) {
Set<Waypoint> s = current.getRoute();
Iterator<Waypoint> i = s.iterator();
if(i.hasNext()) {
long startTime = i.next().getTime();
long endTime = -1;
while(i.hasNext()) {
endTime = i.next().getTime();
}
if(endTime > -1) {
BigDecimal cost = BigDecimal.valueOf(endTime - startTime).
divide(BigDecimal.valueOf(60000));
current.setCost(cost);
payments.pay(current.getCost(), current.getNonce());
}
}
}
rides.save(current);
}
finishRide
I use the route which is ordered based on time to find the start time of the ride
19. public void finishRide(long rideId) {
Ride current = rides.findOne(rideId);
current.setFinished(true);
if(current.isStarted() && current.getNonce() != null) {
Set<Waypoint> s = current.getRoute();
Iterator<Waypoint> i = s.iterator();
if(i.hasNext()) {
long startTime = i.next().getTime();
long endTime = -1;
while(i.hasNext()) {
endTime = i.next().getTime();
}
if(endTime > -1) {
BigDecimal cost = BigDecimal.valueOf(endTime - startTime).
divide(BigDecimal.valueOf(60000));
current.setCost(cost);
payments.pay(current.getCost(), current.getNonce());
}
}
}
rides.save(current);
}
finishRide
I then go to the last element and find the end time of the ride
20. public void finishRide(long rideId) {
Ride current = rides.findOne(rideId);
current.setFinished(true);
if(current.isStarted() && current.getNonce() != null) {
Set<Waypoint> s = current.getRoute();
Iterator<Waypoint> i = s.iterator();
if(i.hasNext()) {
long startTime = i.next().getTime();
long endTime = -1;
while(i.hasNext()) {
endTime = i.next().getTime();
}
if(endTime > -1) {
BigDecimal cost = BigDecimal.valueOf(endTime - startTime).
divide(BigDecimal.valueOf(60000));
current.setCost(cost);
payments.pay(current.getCost(), current.getNonce());
}
}
}
rides.save(current);
}
finishRide
Assuming the ride has more than one Waypoint (otherwise endTime would be -1) we can just charge 1USD per 60 seconds. And payment is effectively done on the
server. Again I oversimplified a lot and ignored basic complexities like the driver forgetting press “Finish".
