How can we get stock market data? How do Google Finance and Yahoo Finance do it?

As all other financial portals do: from market data vendors. There are only few truly international market data vendors: Thomson Reuters, Bloomberg (not counting here as they do provide raw data without their terminal - btw: very smart!), Interactive Data, SIX Telekurs. There are many 2nd tier market data vendors with a specific focus (usually a national). Overall this is a rather dirty complex environment that is mostly transparent to end users as private investors and their professional robbers aehm, I mean the financial advisors ;-)The complexity in a nutshell: the exchanges own the data, so the portals have to pay licenses for displaying data in various qualities as real-time, delayed or end-of-day. Depending on the specific markets and target audience the price range starts at zero and stops somewhere in the outer orbit (of another planet). Violating the terms of the content owner qualifies a financial portal for instant pain so correct permissioning and reporting is a must-have to minimize this business risk. Next is the data itself. Each market has its own model and its own feed format. Parsing this and especially normalizing to a common model is complex. Everywhere outside the states financial portals have to cope with some dozens of international markets. Next is the storage and bandwidth. The inbound traffic of a market data vendor is higher as the output. The latest quote is nice, but end users will need to see charts. To provide the required time-series high-performance specialized data base systems are required able to balance high read and write throughput. Last not least: it is a moving target in any aspect spiced with expensive auditing from time to time. That is the reason why financial portals will also pay license fees to market data vendors.The trend is to provide cloud-like market data services. This way a financial portal developer can pull meaningful building blocks supporting end users in their decisions without the cost to truly understand the data from the technical viewpoint, without the knowledge how to visualize, without the cost of the infrastructure and without the risk of violating the terms and conditions of the content owners.

What are some of the best QR code generators?

The best QR Code generator will depend on what your use case is.If you are using a free QR Code generator, you are probably using static QR Codes -QR Codes that display content like barcodes. Static QR Codes cannot be edited and do not have tracking capabilities. While these work alright in basic cases (such as for teachers in classrooms) they do have very limited capabilities.I am listing the advantages of using Dynamic QR Codes and additional features that every good/professional QR Code generator should have:No limit on scansNo ads (Yes. Some generators include ads)Edit content without changing the design of the code (Dynamic QR Codes)Track number of scans by time, geography, and deviceAbility to create simple mobile landing pages with the QR CodesActivate/De-activate codes as per campaign needsUse advanced design effects to create personalized QR CodesDownload and export vector images (required for printing)Bulk generation of QR CodesLead generation feature to know who is scanning the QR CodeAPI integration for adding QR Code generation to your own app or information systemHere is quick comparison of the popular QR Code Generators on the web for your reference:This data has been sourced from the information available on each website as of Jan 2017.[Full Disclosure: I am a Cofounder of Scanova]

If I have app and I have 10000 users using this app, how much I will earn from admob?

Well, I guess if you have 10000 active user and they generate multiple impression of ads, let suppose 2 impression per user. Then you got approx 20000 impression per day. If you are implementing only banner ads and as the banner ads have very less CTR like 0.5% you will get approximately 100 click on ads. This is just an approximation, actual value may differ. Now it all depends on CPC of ads that you get. Now a days, admob ads CPC is not high as it was before. You will only get high quality ads( ads with higher CPC) when you have a more no. of downloads. Currently its about 0.03 $. So, you will be making aprox 3–6$ per day. Note that this is only assumption as my app has also generated 1$ in only 4 clicks on ads. This can vary from time to time.Meanwhile you can try my app.Music Player - Android Apps on Google PlayHope you would like this app :)

How do I do load testing of my API calls?

Hi,To be able to load test your API calls, you will need of course a load testing solution but also the proper method.Regarding the load testing solution, as you can see there are many solutions available on the market.Load testing API requires the following features from a loadtesting solution:- support of SOAP, REST, JSON, etc.- integration with Continuous Integration servers- ability to import external datasets- ability to create SLAs- Monitoring of all the different layers of the architecture (OS, webserver, application server, etc.)- ability to integrate with any profiling tools- ability to generate load from the CloudRegarding the methods, it really depends if you are working in an agile environment. Testing all APIs doesn't make sense. That's why defining the scope of your performance testing strategy with a method such as ATAM is important.I recommend that you read the following blog post: Load Testing at the Speed of Agile: Q&A with Henrik RexedIt presents lots of interesting best practices regarding component testing (API testing).Best regards,Henrik Rexed

Is there a way to aggregate bandwidth from multiple accessible internet connections into a bigger, faster connection?

Not exactly; while it is possible to have multiple connections to your system, the bandwidth is not aggregated.Remember that each interface on your PC has a separate IP address; traffic sent out via one will generate a return response via the same address.Software solutions perform 'load balancing' to try and distribute traffic across the interfaces, in a variety of ways, for example you might favour one interface for a VPN connection to the office, and another for VoIP traffic, and route general traffic to the third, or even change things dynamically.But what you cannot easily do is present all the interfaces as a single connection with a bandwidth equal to the sum. Most routers that support multiple WAN connections in hardware will simply offer some form of load balancing like this - though in many cases that's sufficient.If you want to aggregate multiple connections, you really need to start with a provider that makes that possible; for example, some providers offer solutions where two or more DSL lines can be 'bonded' together to provide extra capacity, or where an ISDN channel can be added to a connection to provide extra bandwidth on demand. These, however, typically present one IP address at each endpoint, and so appear to the network as a single connection, regardless of the number of physical links.In the scenario in the question, you would have three different IP addresses, from three different providers. If you are engaged in, say, a high bandwidth download and want to use the total bandwidth available, you would need the remote system to send some of the packets to different IP addresses, which just isn't the way the network works.
